test(harness): fix T10 by driving daemon respawn from a main-side eipc call

T10 was passing on older bundles where the cowork client retried the
VM-service connection on a polling cadence — every retry tick was an
implicit trigger for the patched cooldown-gated auto-launch. Post-
1.5354.0 the client opens a persistent socket at boot (zI/E\$i happy
path → KSt) and routes every subsequent RPC through it, so steady
state has no traffic. After SIGKILL the persistent socket goes dead
but no client code is in flight, so kUe()'s catch branch never enters
and the daemon stays gone.

The case-doc claim is upheld by the production code; the patch is
correctly applied (`_lastSpawn` × 3 in installed asar, `_svcLaunched`
× 0). Only the test's trigger model was stale.

Three changes:

1. Wait for `userLoaded`, not `mainVisible`. The post-kill RPC has to
   land in a webContents whose URL matches `claude.ai`; pre-login
   `/login/...` URLs aren't reachable via that filter.

2. Phase 3 fires a daemon RPC each iteration. The renderer wrapper
   (`window['claude.web'].ClaudeVM.getRunningStatus`) was the obvious
   first try but was unreliable: 29/30 calls threw `Cannot find
   context with specified id` because the dead-daemon state forces a
   renderer re-render that invalidates the cached execution context.
   Switched to invoking the eipc handler from MAIN directly via
   `wc.ipc._invokeHandlers.get(channel)(fakeEvent)` with
   `senderFrame.url = 'https://claude.ai/'`. The handler still goes
   through zI/VsA/kUe, the dead socket still throws, the cooldown
   gate still opens, and the patched fork still fires — just without
   any renderer dependency. Three consecutive runs at 21.0s.

3. Budget bumped 20s → 30s. The 10s cooldown is a hard floor, and the
   daemon needs another second or two to bind the socket; 20s was on
   the edge.

Telemetry now reports `rpcAttempts` / `rpcFailures` /
`globalDaemonPidFinal` (the patched `__coworkDaemonPid` global) so
future regressions can be diagnosed from the failure attachment alone.

-
-## Project Overview
-
-This project repackages Claude Desktop (Electron app) for Debian/Ubuntu Linux, applying necessary patches for Linux compatibility.
-
-## Learnings
-
-The [`docs/learnings/`](docs/learnings/) directory contains hard-won technical knowledge from debugging and fixing issues — things that aren't obvious from reading the code or docs alone. Consult these before working on related areas. Add new entries when you discover something non-obvious that would save future contributors (human or AI) significant time.
-
-- [`nix.md`](docs/learnings/nix.md) — NixOS packaging, Electron resource path resolution, testing without NixOS
-- [`cowork-vm-daemon.md`](docs/learnings/cowork-vm-daemon.md) — Cowork VM daemon lifecycle, respawn logic, crash diagnosis
-- [`plugin-install.md`](docs/learnings/plugin-install.md) — Anthropic & Partners plugin install flow, gate logic, backend endpoints, and DevTools recipes
-- [`apt-worker-architecture.md`](docs/learnings/apt-worker-architecture.md) — APT/DNF binary distribution via Cloudflare Worker + GitHub Releases, redirect chain, credential ownership, heartbeat runbook
-- [`tray-rebuild-race.md`](docs/learnings/tray-rebuild-race.md) — why destroy + recreate on `nativeTheme` updates briefly duplicates the tray icon on KDE Plasma, and the in-place `setImage` + `setContextMenu` fast-path that avoids the SNI re-registration race
-- [`mcp-double-spawn.md`](docs/learnings/mcp-double-spawn.md) — Stdio MCPs spawn 2× when chat and Code/Agent panels are both active, root cause in upstream session managers, MCP-author workaround
-- [`linux-topbar-shim.md`](docs/learnings/linux-topbar-shim.md) — why claude.ai's in-app topbar is missing on Linux, the four gates that hide it, why the upstream `frame:false` + WCO config has unclickable buttons on X11 (Chromium-level implicit drag region), and the resolution: hybrid mode (system frame + UA-spoof shim → stacked layout, full button functionality)
-- [`test-harness-electron-hooks.md`](docs/learnings/test-harness-electron-hooks.md) — why constructor-level `BrowserWindow` wraps are silently bypassed by `frame-fix-wrapper`'s Proxy, and the prototype-method hook pattern that works (used by the Quick Entry test runners)
-- [`test-harness-ax-tree-walker.md`](docs/learnings/test-harness-ax-tree-walker.md) — five non-obvious traps in the v7 fingerprint walker after the AX-tree migration: AX-enable async lag, navigateTo-to-same-URL no-op, claude.ai's flat `dialog>button[]` lists, the `more options for X` per-row shape, and sidebar virtualization vs the lookup-failure threshold
-- [`patching-minified-js.md`](docs/learnings/patching-minified-js.md) — general lessons from maintaining a long-lived patch suite against an actively re-minified upstream: anchor selection (literals over identifiers), the `\w` vs `$` identifier-capture trap, beautified false-negatives, idempotency guards, multi-site coordination, non-unique anchor disambiguation, and the SHA-256-pinned hypothesis-verification recipe
-
-## Code Style
-
-All shell scripts in this project must follow the [Bash Style Guide](docs/styleguides/bash_styleguide.md). Key points:
-
-- Tabs for indentation, lines under 80 characters (exception: URLs and regex patterns)
-- Use `[[ ]]` for conditionals, `$(...)` for command substitution
-- Single quotes for literals, double quotes for expansions
-- Lowercase variables; UPPERCASE only for constants/exports
-- Use `local` in functions, avoid `set -e` and `eval`
-
-### Anti-patterns
-
-- **Don't `set -e`.** It interacts badly with `$(...)` capture and function return values, and the project has historically debugged enough silent exits to settle the question. Check status explicitly: `cmd || handle_err`.
-- **Don't `eval`.** Use arrays for argv composition (`cmd "${args[@]}"`). `eval` defeats every parser and is a permanent SC2046 magnet.
-- **Don't use POSIX `[ ... ]`.** Always `[[ ... ]]`. POSIX `[` mis-parses unquoted expansions in ways `[[` does not.
-- **Don't backtick.** Always `$(...)`. Backticks don't nest cleanly and conflict with markdown when patches are pasted into PR comments.
-- **Don't hardcode the work directory.** Scripts that operate during a build use `$work_dir` (set by `build.sh`). A hardcoded path silently breaks the AppImage build, which runs in a different layout from the deb/rpm builds.
-- **Don't wrap commands in `if cmd; then true; else false; fi`-style scaffolding.** Just `cmd` — the exit code is already there.
-- **Don't append to a baseline file to silence `shellcheck`.** Fix the underlying issue. If a warning is genuinely a false positive, use a per-line `# shellcheck disable=SCXXXX` with a comment explaining why.
-
-### Linting
-
-Shell scripts are checked with `shellcheck` and GitHub Actions workflows with `actionlint` before pushing. When lint issues are found:
-
-1. **Fix the code** - Correct the underlying issue rather than suppressing the warning
-2. **Disable directives are a last resort** - Only use `# shellcheck disable=SCXXXX` when:
-   - The warning is a false positive
-   - The pattern is intentional and unavoidable
-   - Always add a comment explaining why the disable is needed
-3. **Run `/lint` to check manually** - Use this skill to check for issues before pushing
-
-## Docs
-
-- **One declarative sentence then a code block or list at the top of every page.** No "In this guide we will explore…" preamble. See [`docs/styleguides/docs_styleguide.md`](docs/styleguides/docs_styleguide.md).
-- **Lowercase kebab-case filenames** for everything in `docs/`. Order belongs in [`docs/index.md`](docs/index.md), not filenames or numeric prefixes.
-- **Real domain nouns over `foo`/`bar`** in walkthroughs. The project vocabulary is `patches`, `the launcher`, `the worker`, `app.asar`, `the minified bundle`, `the asar archive`, `the doctor surface`.
-- **Subsystem deep-dives go under [`docs/learnings/`](docs/learnings/).** Surfacing knowledge there beats burying it in commit messages or in patch-script comments. Add an entry when you discover something non-obvious that would save the next contributor significant time.
-- **Decisions go in [`docs/decisions.md`](docs/decisions.md) (ADR format).** Don't relitigate a settled direction inside a how-to page; link the decision instead.
-- **Troubleshooting headings are the literal symptom**, not editorialized prose. `## Black screen on Fedora KDE under Wayland`, not `## Troubles with Wayland`. Search ranks headings.
-- **CHANGELOG follows [Keep a Changelog 1.1.0](https://keepachangelog.com/en/1.1.0/).** Bullets grouped under Added / Fixed / Changed / Deprecated / Removed / Security; one bullet per change; PR link for the deep dive; inline **BREAKING** prefix for breaking changes. See [`CHANGELOG.md`](CHANGELOG.md) for the current state and [`RELEASING.md`](RELEASING.md) for when entries get promoted from `[Unreleased]`.
-
-## GitHub Workflow
-
-### General Approach
-
-- Use `gh` CLI for all GitHub interactions
-- Create branches based on issue numbers: `fix/123-description` or `feature/123-description`
-- Reference issues in commits and PRs with `#123` or `Fixes #123`
-- After creating a PR, add a comment to the related issue with a summary and link to the PR
-
-### Investigating Issues
-
-For older issues, review the state of the code when the issue was raised - it may have already been addressed:
-
-```bash
-# Get issue creation date
-gh issue view 123 --json createdAt
-
-# Find the commit just before the issue was created
-git log --oneline --until="2025-08-23T08:48:35Z" -1
-
-# View a file at that point in time
-git show <commit>:path/to/file.sh
-
-# Search for relevant changes since the issue was created
-git log --oneline --after="2025-08-23" -- path/to/file.sh
-
-# View a specific commit that may have fixed the issue
-git show <commit>
-```
-
-This helps identify if the issue was already fixed, and allows referencing the specific commit in the response.
-
-### Attribution
-
-**For PR descriptions**, include full attribution:
-
-```
----
-Generated with [Claude Code](https://claude.ai/code)
-Co-Authored-By: Claude <model-name> <noreply@anthropic.com>
-<XX>% AI / <YY>% Human
-Claude: <what AI did>
-Human: <what human did>
-```
-
-- Use the actual model name (e.g., `Claude Opus 4.5`, `Claude Sonnet 4`)
-- The percentage split should honestly reflect the contribution balance for that specific work
-- This provides a trackable record of AI-assisted development over time
-
-**For issues and comments**, use simplified attribution:
-
-```
----
-Written by Claude <model-name> via [Claude Code](https://claude.ai/code)
-```
-
-**For commits**, include a Co-Authored-By trailer:
-
-```

-```
-
-### Contributor Credits
-
-The README Acknowledgments section credits external contributors in chronological order (by merge date or fix date). Update it when:
-
-1. **Merging an external PR** — Add the author to the Acknowledgments list with a link to their GitHub profile and a brief description of their contribution.
-2. **Implementing a fix suggested in an issue** — If an issue author (or commenter) provided a concrete fix, workaround, code snippet, or detailed technical analysis that was directly used, credit them too.
-
-Contributors are listed in chronological order: inspirational projects first (k3d3, emsi, leobuskin), then contributors ordered by when their contribution was merged or implemented.
-
-## Working with Minified JavaScript
-
-### Important Guidelines
-
-1. **Always use regex patterns** when modifying the source JavaScript. Patches live in `scripts/patches/*.sh` (one file per subsystem: `tray.sh`, `cowork.sh`, `claude-code.sh`, etc.); `build.sh` is only an orchestrator that sources them. Variable and function names are minified and **change between releases**.
-
-2. **The beautified code in `build-reference/` has different spacing** than the actual minified code in the app. Patterns must handle both:
-   - Minified: `oe.nativeTheme.on("updated",()=>{`
-   - Beautified: `oe.nativeTheme.on("updated", () => {`
-
-3. **Use `-E` flag with sed** for extended regex support when patterns need grouping or alternation.
-
-4. **Extract variable names dynamically** rather than hardcoding them. Shared extraction helpers live in `scripts/patches/_common.sh`. Example:
-   ```bash
-   # Extract function name from a known pattern
-   TRAY_FUNC=$(grep -oP 'on\("menuBarEnabled",\(\)=>\{\K[$\w]+(?=\(\)\})' app.asar.contents/.vite/build/index.js)
-   ```
-
-5. **Handle optional whitespace** in regex patterns:
-   ```bash
-   # Bad: assumes no spaces
-   sed -i 's/oe.nativeTheme.on("updated",()=>{/...'
-
-   # Good: handles optional whitespace
-   sed -i -E 's/(oe\.nativeTheme\.on\(\s*"updated"\s*,\s*\(\)\s*=>\s*\{)/...'
-   ```
-
-### Reference Files
-
-- `build-reference/app-extracted/` - Extracted and beautified source for analysis
-- `build-reference/tray-icons/` - Tray icon assets for reference
-
-## Frame Fix Wrapper
-
-The app uses a wrapper system to intercept and fix Electron behavior for Linux:
-
-- **`frame-fix-wrapper.js`** - Intercepts `require('electron')` to patch BrowserWindow defaults (e.g., `frame: true` for proper window decorations on Linux)
-- **`frame-fix-entry.js`** - Entry point that loads the wrapper before the main app
-
-These are injected by `scripts/patches/app-asar.sh` (inside `patch_app_asar`) and referenced in `package.json`'s `main` field. The wrapper pattern allows fixing Electron behavior without modifying the minified app code directly.
-
-## Setting Up build-reference
-
-If `build-reference/` is missing or you need to inspect source for a new version, follow these steps to download, extract, and beautify the source code.
-
-### Prerequisites
-
-```bash
-# Install required tools
-sudo apt install p7zip-full wget nodejs npm
-
-# Install asar and prettier globally (or use npx)
-npm install -g @electron/asar prettier
-```
-
-### Step 1: Download the Windows Installer
-
-The Windows installer contains the app.asar which has the full Electron app source.
-
-```bash
-# Create working directory
-mkdir -p build-reference && cd build-reference
-
-# Download URL pattern (update version as needed):
-# x64: https://downloads.claude.ai/releases/win32/x64/VERSION/Claude-COMMIT.exe
-# arm64: https://downloads.claude.ai/releases/win32/arm64/VERSION/Claude-COMMIT.exe
-
-# Example for version 1.1.381:
-wget -O Claude-Setup-x64.exe "https://downloads.claude.ai/releases/win32/x64/1.1.381/Claude-c2a39e9c82f5a4d51f511f53f532afd276312731.exe"
-```
-
-### Step 2: Extract the Installer
-
-```bash
-# Extract the exe (it's a 7z archive)
-7z x -y Claude-Setup-x64.exe -o"exe-contents"
-
-# Find and extract the nupkg
-cd exe-contents
-NUPKG=$(find . -name "AnthropicClaude-*.nupkg" | head -1)
-7z x -y "$NUPKG" -o"nupkg-contents"
-cd ..
-
-# Copy out the important files
-cp exe-contents/nupkg-contents/lib/net45/resources/app.asar .
-cp -a exe-contents/nupkg-contents/lib/net45/resources/app.asar.unpacked .
-
-# Optional: copy tray icons for reference
-mkdir -p tray-icons
-cp exe-contents/nupkg-contents/lib/net45/resources/*.png tray-icons/ 2>/dev/null || true
-cp exe-contents/nupkg-contents/lib/net45/resources/*.ico tray-icons/ 2>/dev/null || true
-```
-
-### Step 3: Extract app.asar
-
-```bash
-# Extract the asar archive
-asar extract app.asar app-extracted
-```
-
-### Step 4: Beautify the JavaScript Files
-
-The extracted JS files are minified. Use prettier to make them readable:
-
-```bash
-# Beautify all JS files in the build directory
-npx prettier --write "app-extracted/.vite/build/*.js"
-
-# Or beautify specific files
-npx prettier --write app-extracted/.vite/build/index.js
-npx prettier --write app-extracted/.vite/build/mainWindow.js
-```
-
-### Step 5: Clean Up (Optional)
-
-```bash
-# Remove intermediate files, keep only what's needed for reference
-rm -rf exe-contents
-rm Claude-Setup-x64.exe
-rm -rf app.asar app.asar.unpacked  # Keep only app-extracted
-```
-

-## Adding New Package Formats or Repositories
-
-When adding support for new distribution formats (e.g., RPM, Flatpak, Snap) or package repositories, follow these guidelines to avoid iterative debugging in CI.
-
-### Research Before Implementing
-
-1. **Understand the target system's constraints** - Each package format has specific rules:
-   - Version string formats (e.g., RPM cannot have hyphens in Version field)
-   - Required metadata fields
-   - Signing requirements and tools
-
-2. **Search for existing CI implementations** - Look for "GitHub Actions [format] signing" or similar. Existing workflows reveal required flags, environment setup, and common pitfalls.
-
-3. **Check tool behavior in non-interactive environments** - CI has no TTY. Tools like GPG need flags like `--batch` and `--yes` to work without prompts.
-
-### Consider Concurrency
-
-1. **Multiple jobs writing to the same branch will race** - If APT and DNF repos both push to `gh-pages`, add:
-   - Job dependencies (`needs: [other-job]`), or
-   - Retry loops with `git pull --rebase` before push
-
-2. **External processes may also modify branches** - GitHub Pages deployment runs automatically and can cause push conflicts.
-
-### Test the Full Pipeline
-
-1. **Test CI steps locally first** - Run the signing/packaging commands manually to catch errors before committing.
-
-2. **Use a test tag for new infrastructure** - Create a non-release tag to validate the full CI pipeline before merging to main.
-
-3. **Verify the end-user experience** - After CI succeeds, actually test the install commands from the README on a clean system.
-
-### Common CI Pitfalls
-
-| Issue | Solution |
-|-------|----------|
-| GPG "cannot open /dev/tty" | Add `--batch` flag |
-| GPG "File exists" error | Add `--yes` flag to overwrite |
-| Push rejected (ref changed) | Add `git pull --rebase` before push, with retry loop |
-| Version format invalid | Research target format's version constraints upfront |
-| Signing key not found | Ensure key is imported before signing step, check key ID output |
-
-## CI/CD
-
-### Triggering Builds
-
-```bash
-# Trigger CI on a branch
-gh workflow run CI --ref branch-name
-
-# Watch the run
-gh run watch RUN_ID
-
-# Download artifacts
-gh run download RUN_ID -n artifact-name
-```
-
-### Build Artifacts
-
-- `claude-desktop-VERSION-amd64.deb` - Debian package for x86_64
-- `claude-desktop-VERSION-amd64.AppImage` - AppImage for x86_64
-- `claude-desktop-VERSION-arm64.deb` - Debian package for ARM64
-- `claude-desktop-VERSION-arm64.AppImage` - AppImage for ARM64
-- `result/` - Nix build output (symlink, gitignored)
-
-## Distribution
-
-APT and DNF binaries are fronted by a Cloudflare Worker at `pkg.claude-desktop-debian.dev`. Metadata (`InRelease`, `Packages`, `KEY.gpg`, `repodata/*`) passes through to the `gh-pages` branch; binary requests (`/pool/.../*.deb`, `/rpm/*/*.rpm`) get 302'd to the corresponding GitHub Release asset. This keeps `.deb` / `.rpm` files out of `gh-pages` entirely, so they never hit GitHub's 100 MB per-file push cap.
-
-Key files:
-- `worker/src/worker.js` — Worker source
-- `worker/wrangler.toml` — Worker config (route, `custom_domain = true`)
-- `.github/workflows/deploy-worker.yml` — deploys on push to `main` when `worker/**` changes
-- `.github/workflows/apt-repo-heartbeat.yml` — daily chain validation, auto-opens tracking issue on failure
-- `update-apt-repo` and `update-dnf-repo` jobs in `.github/workflows/ci.yml` — gate a strip step on Worker liveness, so binaries are removed from the local pool tree before push
-
-Repo secrets: `CLOUDFLARE_API_TOKEN`, `CLOUDFLARE_ACCOUNT_ID`. Token scoped to the "Edit Cloudflare Workers" template.
-
-Full details including the redirect chain, the http-scheme-downgrade gotcha, credential ownership, and heartbeat failure runbook: [`docs/learnings/apt-worker-architecture.md`](docs/learnings/apt-worker-architecture.md).
-
-## Testing
-
-### Local Build
-
-```bash
-./build.sh --build appimage --clean no
-```
-
-### Nix Build
-
-```bash
-nix build .#claude-desktop
-nix build .#claude-desktop-fhs
-```
-
-### Testing AppImage
-
-```bash
-# Run with logging
-./test-build/claude-desktop-*.AppImage 2>&1 | tee ~/.cache/claude-desktop-debian/launcher.log
-```
-
-## Debugging Workflow
-
-### Inspecting the Running App's Code
-
-```bash
-# Find the mounted AppImage path
-mount | grep claude
-# Example: /tmp/.mount_claudeXXXXXX
-
-# Extract the running app's asar for inspection
-npx asar extract /tmp/.mount_claudeXXXXXX/usr/lib/node_modules/electron/dist/resources/app.asar /tmp/claude-inspect
-
-# Search for patterns in the extracted code
-grep -n "pattern" /tmp/claude-inspect/.vite/build/index.js
-```
-
-### Checking DBus/Tray Status
-
-```bash
-# List registered tray icons
-gdbus call --session --dest=org.kde.StatusNotifierWatcher \
-  --object-path=/StatusNotifierWatcher \
-  --method=org.freedesktop.DBus.Properties.Get \
-  org.kde.StatusNotifierWatcher RegisteredStatusNotifierItems
-
-# Find which process owns a DBus connection
-gdbus call --session --dest=org.freedesktop.DBus \
-  --object-path=/org/freedesktop/DBus \
-  --method=org.freedesktop.DBus.GetConnectionUnixProcessID ":1.XXXX"
-```
-
-### Log Locations
-
-- Launcher log: `~/.cache/claude-desktop-debian/launcher.log`
-- App logs: `~/.config/Claude/logs/`
-- Run with logging: `./app.AppImage 2>&1 | tee ~/.cache/claude-desktop-debian/launcher.log`
-
-## Useful Locations

-- Logs: `~/.config/Claude/logs/`
-- SingletonLock: `~/.config/Claude/SingletonLock`
-- Launcher log: `~/.cache/claude-desktop-debian/launcher.log`
-
-## Versioning
-
-Release versions are managed via two GitHub Actions repository variables (not files):
-
-- **`REPO_VERSION`** - The project's own version (e.g., `1.3.23`). Bump this manually via `gh variable set REPO_VERSION --body "X.Y.Z"` when shipping project changes.
-- **`CLAUDE_DESKTOP_VERSION`** - The upstream Claude Desktop version (e.g., `1.1.8629`). Updated automatically by the `check-claude-version` workflow when a new upstream release is detected.

-Tags follow the pattern `v{REPO_VERSION}+claude{CLAUDE_DESKTOP_VERSION}`, e.g., `v1.3.23+claude1.1.7714`. Pushing a tag triggers the CI release build.
-
-```bash
-# Check current values
-gh variable get REPO_VERSION
-gh variable get CLAUDE_DESKTOP_VERSION
-
-# Bump repo version and tag a release
-gh variable set REPO_VERSION --body "1.3.24"
-git tag "v1.3.24+claude$(gh variable get CLAUDE_DESKTOP_VERSION)"
-git push origin "v1.3.24+claude$(gh variable get CLAUDE_DESKTOP_VERSION)"
-```
-
-When upstream Claude Desktop updates, the `check-claude-version` workflow automatically updates `CLAUDE_DESKTOP_VERSION`, patches the URLs in `scripts/setup/detect-host.sh`, and creates a new tag — no manual intervention needed.
-
-## Common Gotchas
-
-- **`.zsync` files** - Used for delta updates, can be ignored/deleted
-- **AppImage mount points** - Running AppImages mount to `/tmp/.mount_claude*`; check with `mount | grep claude`
-- **Killing the app** - Must kill all electron child processes, not just the main one:
-  ```bash
-  pkill -9 -f "mount_claude"
-  ```
-- **SingletonLock** - If app won't start, check for stale lock: `~/.config/Claude/SingletonLock`
-- **Node version** - Build requires Node.js; the script downloads its own if needed
-- **Nix hashes** - When Claude Desktop version changes, both the URLs in `scripts/setup/detect-host.sh` and `nix/claude-desktop.nix` (version, URLs, SRI hashes) must be updated. The CI handles this automatically.
-- **Claude Desktop version** - A GitHub Action automatically updates the `CLAUDE_DESKTOP_VERSION` repo variable and the URLs in `scripts/setup/detect-host.sh` on main when a new version is detected. Before committing `scripts/setup/detect-host.sh`, ensure your branch has the latest URLs:
-  ```bash
-  # Check repo variable (source of truth)
-  gh variable get CLAUDE_DESKTOP_VERSION
-
-  # Check current version in the detect_architecture case statement
-  grep -oP 'x64/\K[0-9]+\.[0-9]+\.[0-9]+' scripts/setup/detect-host.sh | head -1
-
-  # If outdated, pull URLs from main branch
-  gh api repos/aaddrick/claude-desktop-debian/contents/scripts/setup/detect-host.sh?ref=main \
-    --jq '.content' | base64 -d | grep -E "claude_download_url="
-  ```
-  Update both amd64 and arm64 URLs in `detect_architecture()` to match main
+- `.claude/agents/` - Specialized subagent definitions for the Task tool
+- `.claude/skills/` - User-invocable skills (slash commands)
+- `.claude/scripts/` - Orchestration scripts that chain multiple Claude CLI calls

-# Changelog
-
-All notable changes to `aaddrick/claude-desktop-debian` are documented in this file.
-
-The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/) — semantic versioning applies to `REPO_VERSION`; upstream Claude Desktop bumps (the `+claude{X.Y.Z}` suffix on the tag) are tracked separately by the `check-claude-version` workflow.
-
-## [Unreleased]
-
-<!-- Updated automatically by check-claude-version; will be current at release time. -->
-
-## [v2.0.15] — 2026-05-27
-
-Tracks upstream Claude Desktop 1.9255.0.
-
-### Fixed
-
-- `StartupWMClass` aligned to `Claude` to match what Electron actually advertises via `productName`. The v2.0.14 value `claude-desktop` was silently ignored by Electron, causing orphan windows and duplicate gear icons on GNOME/KDE. Value centralized from 6 hardcoded locations to one source of truth in `build.sh`, with build-time substitution and a `productName` assertion guard. ([#655](https://github.com/aaddrick/claude-desktop-debian/pull/655), fixes [#652](https://github.com/aaddrick/claude-desktop-debian/issues/652))
-
-## [v2.0.14] — 2026-05-25
-
-Tracks upstream Claude Desktop 1.8555.2.
-
-### Fixed
-
-- `WM_CLASS` and `StartupWMClass` aligned to `claude-desktop` across all formats (deb, RPM, AppImage, autostart). Resolves ambiguity with the Claude Code CLI (`claude`) and ensures consistent taskbar grouping on KDE/GNOME. ([#648](https://github.com/aaddrick/claude-desktop-debian/pull/648), fixes [#647](https://github.com/aaddrick/claude-desktop-debian/issues/647))
-
-### Changed
-
-- AppImage smoke test: replaced flat 10s sleep with readiness-marker poll (30s ceiling, 0.5s tick), unified cleanup trap to prevent 190MB `squashfs-root` leaks on interrupt. ([#646](https://github.com/aaddrick/claude-desktop-debian/pull/646))
-
-## [v2.0.13] — 2026-05-24
-
-Tracks upstream Claude Desktop 1.8555.2.
-
-### Added
-
-- `CLAUDE_KEEP_AWAKE=0` env var to suppress `powerSaveBlocker` sleep inhibitor that upstream holds indefinitely on Linux (no lifecycle management). Adds diagnostic logging for all `powerSaveBlocker` calls and `--doctor` visibility. ([#605](https://github.com/aaddrick/claude-desktop-debian/issues/605))
-- `--doctor` flags filesystems with `NAME_MAX < 200` (eCryptfs, certain encrypted overlays) and surfaces the LUKS-symlink workaround for cowork. Thanks @RayCharlizard, @lizthegrey for the repro. ([#614](https://github.com/aaddrick/claude-desktop-debian/pull/614), fixes [#590](https://github.com/aaddrick/claude-desktop-debian/issues/590))
-- F11 fullscreen toggle via hidden menu accelerator — Linux parity with macOS green button / Windows F11. ([#638](https://github.com/aaddrick/claude-desktop-debian/pull/638), fixes [#580](https://github.com/aaddrick/claude-desktop-debian/issues/580))
-- Linux org-plugins path (`/etc/claude/org-plugins`) added to platform switch, enabling MDM-managed plugin configuration. ([#639](https://github.com/aaddrick/claude-desktop-debian/pull/639), fixes [#607](https://github.com/aaddrick/claude-desktop-debian/issues/607))
-- Top-level governance docs: this `CHANGELOG.md`, [`RELEASING.md`](RELEASING.md) (pre-release checklist + tag-driven CI flow), [`SECURITY.md`](SECURITY.md) (private GHSA reporting + in/out-of-scope), [`docs/index.md`](docs/index.md) (navigation hub), and [`docs/styleguides/docs_styleguide.md`](docs/styleguides/docs_styleguide.md) (page anatomy, naming, antipatterns). [`CLAUDE.md`](CLAUDE.md) gains explicit § Required reading, § Anti-patterns, and § Docs sections; [`AGENTS.md`](AGENTS.md) becomes a byte-identical mirror of the new body (was a 13-line stub) so non-Claude tools get the same instructions.
-- [`CONTRIBUTING.md`](CONTRIBUTING.md) "Before you start" triage section: where to go for a bug, a fix-in-hand, a new-feature ask, or a security report.
-- `--password-store` keyring detection: probes D-Bus for kwallet6 / gnome-libsecret at startup and injects the flag before the app path, fixing session persistence on KDE Plasma and other desktops where `safeStorage.isEncryptionAvailable()` returned false. Adds `CLAUDE_PASSWORD_STORE` env override and `--doctor` diagnostic. Thanks @dubreal. ([#611](https://github.com/aaddrick/claude-desktop-debian/pull/611), fixes [#593](https://github.com/aaddrick/claude-desktop-debian/issues/593))
-- Unzip fallback for Node 24: detects missing electron binary after `extract-zip` silently no-ops and recovers from the `@electron/get` cache using system `unzip`. Thanks @JustinJLeopard. ([#631](https://github.com/aaddrick/claude-desktop-debian/pull/631), fixes [#584](https://github.com/aaddrick/claude-desktop-debian/issues/584))
-
-### Fixed
-
-- Config writes no longer drop externally-added `mcpServers`. The stale in-memory cache was overwriting disk on every preference change; now re-reads `mcpServers` from disk before each write. ([#643](https://github.com/aaddrick/claude-desktop-debian/pull/643), fixes [#400](https://github.com/aaddrick/claude-desktop-debian/issues/400))
-- Menu bar toggle fires on Alt keyup only, not keydown — fixes Alt+Shift (language switch) and Alt+F4 accidentally triggering the menu bar. `CLAUDE_MENU_BAR=hidden` disables the Alt toggle entirely. ([#642](https://github.com/aaddrick/claude-desktop-debian/pull/642), fixes [#630](https://github.com/aaddrick/claude-desktop-debian/issues/630))
-- `.asar` paths rejected in directory check, preventing Electron's ASAR VFS shim from dispatching `app.asar` to Cowork as a "folder drop". Fixes permission dialog on every launch, forced Cowork mode on reopen from tray, and "No conversation found" loop in Claude Code >=2.1.111. ([#640](https://github.com/aaddrick/claude-desktop-debian/pull/640), fixes [#383](https://github.com/aaddrick/claude-desktop-debian/issues/383), [#622](https://github.com/aaddrick/claude-desktop-debian/issues/622), [#632](https://github.com/aaddrick/claude-desktop-debian/issues/632))
-- Identifier captures across all patch scripts hardened from `\w+` to `[$\w]+` (PCRE) / `[[:alnum:]_$]+` (ERE). Fixes broken idempotency guard in `tray.sh`, adds missing guards to `cowork.sh` patches 6/9/10, adds `\s*` whitespace tolerance to multiple patterns. ([#644](https://github.com/aaddrick/claude-desktop-debian/pull/644))
-- `exec` before Electron invocation in deb, RPM, and Nix launchers so Ctrl+C and signals forward correctly to the Electron process. ([#637](https://github.com/aaddrick/claude-desktop-debian/pull/637), fixes [#424](https://github.com/aaddrick/claude-desktop-debian/issues/424))
-- `--class=Claude` added to launcher args ensuring WM_CLASS matches `StartupWMClass` in the .desktop file, preventing GNOME extension crashes from unexpected class values. ([#636](https://github.com/aaddrick/claude-desktop-debian/pull/636), ref [#635](https://github.com/aaddrick/claude-desktop-debian/issues/635))
-- Sloppy/focus-follows-mouse: suppress redundant `webContents.focus()` calls that trigger X11 `_NET_ACTIVE_WINDOW` raise-on-hover. Grace window handles stale `isFocused()` on tray-restore and minimize-restore. Thanks @tkrag. ([#589](https://github.com/aaddrick/claude-desktop-debian/pull/589), fixes [#416](https://github.com/aaddrick/claude-desktop-debian/issues/416))
-- Tray: extracted JS identifier captures now accept `$` so the 1.8089.1 minified bundle ('`i$A`' menu handler) matches. Switches `\w+` to `[\w$]+`. ([#627](https://github.com/aaddrick/claude-desktop-debian/pull/627), fixes [#625](https://github.com/aaddrick/claude-desktop-debian/issues/625))
-- RPM: silence "File listed twice" warning on `chrome-sandbox` by moving `chmod 4755` into `%install` (replaces `%attr` in `%files`). Adds regression guard that fails the build if the warning reappears. Thanks @JoshuaVlantis. ([#610](https://github.com/aaddrick/claude-desktop-debian/pull/610), fixes [#609](https://github.com/aaddrick/claude-desktop-debian/issues/609))
-- Window close with `CLAUDE_QUIT_ON_CLOSE=1` now actively quits via `app.quit()` instead of relying on the bundled handler that hardcodes hide-to-tray on Linux. Rides upstream's own quit-in-progress guard. Thanks @phelps-matthew. ([#624](https://github.com/aaddrick/claude-desktop-debian/pull/624), fixes [#623](https://github.com/aaddrick/claude-desktop-debian/issues/623))
-- node-pty: wipe upstream Windows binaries (winpty.dll, winpty-agent.exe, Windows `.node` files) before staging the Linux build, preventing PE32+ orphans in the packaged asar. Thanks @JoshuaVlantis. ([#597](https://github.com/aaddrick/claude-desktop-debian/pull/597), addresses [#401](https://github.com/aaddrick/claude-desktop-debian/issues/401))
-
-### Changed
-
-- CI injection hardening: moved `${{ steps.*.outputs.* }}` expressions from `run:` blocks to `env:` blocks in `issue-triage-v2.yml`. Build pipeline: `process.exit(0)` → `process.exit(1)` in `quick-window.sh` when patch anchors aren't found so CI fails instead of shipping broken patches. Packaging scriptlets: replaced `&> /dev/null` with `> /dev/null 2>&1` for dash compatibility in deb/RPM postinst. ([#641](https://github.com/aaddrick/claude-desktop-debian/pull/641))
-- Credit @lizthegrey, @sabiut, @typedrat, @RayCharlizard in README Acknowledgments. ([#626](https://github.com/aaddrick/claude-desktop-debian/pull/626))
-- Troubleshooting: new "Repeated Electron Crashes / GPU Process FATAL" section documenting `CLAUDE_DISABLE_GPU=1`. Adds tuning-rationale comments around the `--doctor` 3-in-7-days threshold and the `coredumpctl` `COMM=electron` assumption. Thanks @sabiut. ([#615](https://github.com/aaddrick/claude-desktop-debian/pull/615), addresses [#608](https://github.com/aaddrick/claude-desktop-debian/issues/608))
-- Docs filenames are now lowercase kebab-case (`docs/building.md`, `docs/configuration.md`, `docs/decisions.md`, `docs/troubleshooting.md`); `STYLEGUIDE.md` moved to [`docs/styleguides/bash_styleguide.md`](docs/styleguides/bash_styleguide.md). Cross-references swept across README, CONTRIBUTING, CODEOWNERS, `.github/`, `.claude/`, `scripts/`, and `claude-desktop --doctor` user-facing output.
-- `[$\w]+` is the codified identifier-capture convention for patch-script regexes (CONTRIBUTING § Patch-script regexes; `patch-engineer` agent examples updated to match). Closes a docs-vs-code gap that left the rule only in [`docs/learnings/patching-minified-js.md`](docs/learnings/patching-minified-js.md) — the same `\w+` trap fixed in patches by [#555](https://github.com/aaddrick/claude-desktop-debian/pull/555) and [#627](https://github.com/aaddrick/claude-desktop-debian/pull/627).

-Tracks upstream Claude Desktop 1.5354.0 (unchanged from v2.0.7).
-
-### Fixed
-
-- Cowork starts again on Claude Desktop 1.5354.0. Upstream's minifier started emitting `$`-containing identifiers (`C$i`, `g$i`); two regex anchors in `scripts/patches/cowork.sh` used `\w+`, which doesn't match `$`. Patch 2b silently no-op'd, the Swift VM module assignment never landed, and you'd hit `Swift VM addon not available` at session init. Widens both anchors to `[\w$]+`. Patch 6 also moves from `indexOf` to `lastIndexOf` on the retry-delay anchor. Thanks @sirfaber, @HumboldtJoker, @zabka. ([#555](https://github.com/aaddrick/claude-desktop-debian/pull/555), fixes [#558](https://github.com/aaddrick/claude-desktop-debian/issues/558), likely fixes [#553](https://github.com/aaddrick/claude-desktop-debian/issues/553) and [#445](https://github.com/aaddrick/claude-desktop-debian/issues/445))

-### Added
-
-- Linux in-app topbar works now. New `hybrid` titlebar mode is the default: native OS frame plus a BrowserView preload shim that satisfies claude.ai's UA gate, so the hamburger, sidebar, search, and nav buttons render and are clickable. Layout is stacked (DE titlebar above the in-app topbar) rather than combined like Windows. Set `CLAUDE_TITLEBAR_STYLE=native` to opt out and hide the in-app topbar. The upstream `frame:false` + WCO config is preserved as `hidden` for investigation but still has unclickable buttons on Linux; `--doctor` warns when it's active. Verified on KDE Plasma X11/Wayland and Hyprland; GNOME, Sway, Niri, and NixOS pending. ([#538](https://github.com/aaddrick/claude-desktop-debian/pull/538))
-
-## [v2.0.6] — 2026-05-01
-
-Tracks upstream Claude Desktop 1.5354.0. Absorbs three upstream bumps from v2.0.5: 1.4758.0, 1.5220.0, 1.5354.0.
-
-### Added
-
-- Cowork bwrap mounts accept a `{src, dst}` form, so you can map a host directory under `$HOME` onto a different path inside the sandbox. Unlocks persistent-`/tmp` so Bash tool calls don't wipe state between invocations. String form unchanged. Thanks @cbonnissent. ([#531](https://github.com/aaddrick/claude-desktop-debian/pull/531))
-- `--doctor` warns when `COWORK_VM_BACKEND` is set to an unknown value instead of silently falling through to auto-detect; adds a `COWORK_VM_BACKEND` row and a Cowork Backend section to `docs/configuration.md`. Thanks @CyPack. ([#324](https://github.com/aaddrick/claude-desktop-debian/issues/324))
-- `--doctor` warns when an additional bwrap mount destination shadows a default sandbox path like `/usr`, `/etc`, `/bin`, `/sbin`, `/lib`. ([#531](https://github.com/aaddrick/claude-desktop-debian/pull/531))
-- Troubleshooting entries for Cowork VM connection timeout, virtiofsd outside `$PATH` on Fedora/RHEL (`/usr/libexec/virtiofsd`), and Fedora tmpfs `EXDEV` errors. ([#324](https://github.com/aaddrick/claude-desktop-debian/issues/324))

-### Fixed

-- Closing the window no longer kills the app on Linux. The X button hides to tray, matching Windows and macOS. Quit explicitly with Ctrl+Q, the tray menu, or your DE's quit shortcut. Set `CLAUDE_QUIT_ON_CLOSE=1` to restore the old behavior. Fixes scheduled tasks and `/schedule` firings getting silently dropped overnight. Thanks @lizthegrey. ([#451](https://github.com/aaddrick/claude-desktop-debian/pull/451))
-- "Run on startup" toggle persists on Linux now. Electron's `setLoginItemSettings` isn't implemented on Linux; the wrapper backs the toggle with `~/.config/autostart/claude-desktop.desktop` per the XDG Autostart spec. Thanks @lizthegrey. ([#450](https://github.com/aaddrick/claude-desktop-debian/pull/450), fixes [#128](https://github.com/aaddrick/claude-desktop-debian/issues/128))
-- Tray icon updates in place on OS theme change instead of briefly duplicating on KDE Plasma. Uses `setImage` + `setContextMenu` rather than destroy + recreate. Thanks @IliyaBrook. ([#515](https://github.com/aaddrick/claude-desktop-debian/pull/515))
-- Window visibility check works again after an upstream minified-name change broke it. Thanks @Andrej730. ([#496](https://github.com/aaddrick/claude-desktop-debian/pull/496), fixes [#495](https://github.com/aaddrick/claude-desktop-debian/issues/495))

-- APT/DNF install instructions point at `pkg.claude-desktop-debian.dev` directly, bypassing the GitHub Pages 301. Pages serves the redirect over `http://` because it can't provision a cert for the `pkg.` subdomain (DNS belongs to the Cloudflare Worker), and `apt` refuses HTTPS→HTTP downgrades. DNF was unaffected. ([#510](https://github.com/aaddrick/claude-desktop-debian/pull/510), [#514](https://github.com/aaddrick/claude-desktop-debian/pull/514))

 - [`test-harness-electron-hooks.md`](docs/learnings/test-harness-electron-hooks.md) — why constructor-level `BrowserWindow` wraps are silently bypassed by `frame-fix-wrapper`'s Proxy, and the prototype-method hook pattern that works (used by the Quick Entry test runners)

-- [`patching-minified-js.md`](docs/learnings/patching-minified-js.md) — general lessons from maintaining a long-lived patch suite against an actively re-minified upstream: anchor selection (literals over identifiers), the `\w` vs `$` identifier-capture trap, beautified false-negatives, idempotency guards, multi-site coordination, non-unique anchor disambiguation, and the SHA-256-pinned hypothesis-verification recipe

 - Lowercase variables; UPPERCASE only for constants/exports
 - Use `local` in functions, avoid `set -e` and `eval`
 
-### Anti-patterns
-
-- **Don't `set -e`.** It interacts badly with `$(...)` capture and function return values, and the project has historically debugged enough silent exits to settle the question. Check status explicitly: `cmd || handle_err`.
-- **Don't `eval`.** Use arrays for argv composition (`cmd "${args[@]}"`). `eval` defeats every parser and is a permanent SC2046 magnet.
-- **Don't use POSIX `[ ... ]`.** Always `[[ ... ]]`. POSIX `[` mis-parses unquoted expansions in ways `[[` does not.
-- **Don't backtick.** Always `$(...)`. Backticks don't nest cleanly and conflict with markdown when patches are pasted into PR comments.
-- **Don't hardcode the work directory.** Scripts that operate during a build use `$work_dir` (set by `build.sh`). A hardcoded path silently breaks the AppImage build, which runs in a different layout from the deb/rpm builds.
-- **Don't wrap commands in `if cmd; then true; else false; fi`-style scaffolding.** Just `cmd` — the exit code is already there.
-- **Don't append to a baseline file to silence `shellcheck`.** Fix the underlying issue. If a warning is genuinely a false positive, use a per-line `# shellcheck disable=SCXXXX` with a comment explaining why.

-- **One declarative sentence then a code block or list at the top of every page.** No "In this guide we will explore…" preamble. See [`docs/styleguides/docs_styleguide.md`](docs/styleguides/docs_styleguide.md).
-- **Lowercase kebab-case filenames** for everything in `docs/`. Order belongs in [`docs/index.md`](docs/index.md), not filenames or numeric prefixes.
-- **Real domain nouns over `foo`/`bar`** in walkthroughs. The project vocabulary is `patches`, `the launcher`, `the worker`, `app.asar`, `the minified bundle`, `the asar archive`, `the doctor surface`.
-- **Subsystem deep-dives go under [`docs/learnings/`](docs/learnings/).** Surfacing knowledge there beats burying it in commit messages or in patch-script comments. Add an entry when you discover something non-obvious that would save the next contributor significant time.
-- **Decisions go in [`docs/decisions.md`](docs/decisions.md) (ADR format).** Don't relitigate a settled direction inside a how-to page; link the decision instead.
-- **Troubleshooting headings are the literal symptom**, not editorialized prose. `## Black screen on Fedora KDE under Wayland`, not `## Troubles with Wayland`. Search ranks headings.
-- **CHANGELOG follows [Keep a Changelog 1.1.0](https://keepachangelog.com/en/1.1.0/).** Bullets grouped under Added / Fixed / Changed / Deprecated / Removed / Security; one bullet per change; PR link for the deep dive; inline **BREAKING** prefix for breaking changes.

-## Filing an issue
-
-1. Use the issue template, not freeform.
-2. Paste full `./build.sh --doctor` (or `claude-desktop --doctor`)
-   output. Most-skipped step.
-3. Include distro, DE, session type (Wayland/X11). Most Linux-only
-   bugs trace to one of these.
-4. Reproduce on a clean config: move `~/.config/Claude` aside, relaunch.
-   Stale config causes false positives.
-
-## Patches against upstream
-
-Patches live in `scripts/patches/*.sh`, one per subsystem; `build.sh`

-
-## Before submitting a PR
-
-- Run `/lint` (or `shellcheck` + `actionlint`). See CLAUDE.md § Linting.

-## Conventions in this file
-
-### Patch-script regexes
-
-Two rules apply to regexes that target the minified upstream bundle.
-
-**Identifier captures use `[$\w]+`, not `\w+`.** Upstream's minifier
-emits `$` inside JS identifiers (`C$i`, `g$i`, `i$A`). `\w` is
-`[A-Za-z0-9_]` and does not match `$`, so a `\w+` capture against
-`$e` returns the suffix `e` instead of the whole identifier. PR #555
-and PR #627 closed two cohorts of patches with this exact bug. The
-learnings doc has the full background and the canonical character
-class is `[$\w]+` (the equivalent `[\w$]+` is fine; either form
-matches the same set, the order is convention only).
-
-**Intent comments accompany whitespace-tolerant patterns.** When a
-patch regex uses `\s*` or `[ \t]*` between tokens, add a one-line
-intent comment with whitespace stripped so the matched shape stays
-readable:
-
-```js
-// Intent: VAR.code==="ENOENT"
-const enoentRe = /([$\w]+)\.code\s*===\s*"ENOENT"/g;
-```
-
-Apply both rules to new patches and to existing regexes when you're
-editing them for other reasons. No churn PRs. Background:
-[the patching-minified-js learnings doc][pmj].
-
-[pmj]: docs/learnings/patching-minified-js.md
-
-### Markdown prose wrapping
-
-Wrap prose at ~80 chars, matching the bash column rule in
-[docs/styleguides/bash_styleguide.md](docs/styleguides/bash_styleguide.md).
-Tables, code blocks, URLs, alt text may exceed when breaking hurts
-readability.

It also reports cowork mode readiness — which isolation backend will be used, and which dependencies (KVM, QEMU, vsock, socat, virtiofsd, bubblewrap) are installed or missing.

-# Releasing
-
-This project ships through tag-driven CI. A tag of the form `v{REPO_VERSION}+claude{CLAUDE_DESKTOP_VERSION}` on `main` triggers the release job in [`.github/workflows/ci.yml`](.github/workflows/ci.yml), which builds for both architectures, attaches the artifacts to a GitHub Release, and updates the APT, DNF, and AUR repositories.
-
-There are two flavors of release:
-
-- **Upstream-tracking retag.** A `check-claude-version` workflow runs daily, detects new Claude Desktop releases, bumps the `CLAUDE_DESKTOP_VERSION` repo variable, patches URLs and SRI hashes in `scripts/setup/detect-host.sh` and `nix/claude-desktop.nix`, and pushes a new tag with the same `REPO_VERSION` and a new `+claude{X.Y.Z}` suffix. **No human action required.** These do not get CHANGELOG entries — they're tracked in the tag suffix.
-- **Project release.** You bumped `REPO_VERSION` because you shipped project changes. Follow the checklist below.
-
-## Pre-release checklist
-
-1. **CI is green on `main`.** All required workflows (CI, tests, shellcheck, codespell) passed on the commit you're about to tag.
-
-   ```bash
-   gh run list --branch main --limit 5
-   ```
-
-2. **`CHANGELOG.md` is updated.** The `[Unreleased]` section now reflects what you're about to ship. Move it under a new `[v{REPO_VERSION}]` heading with today's date.
-
-3. **Local tests pass.**
-
-   ```bash
-   bats tests/
-   shellcheck scripts/**/*.sh build.sh
-   ```
-
-   See [`CLAUDE.md`](CLAUDE.md#linting) for the canonical lint command.
-
-4. **AppImage artifact boots on a clean system.** The `test-artifacts.yml` reusable workflow already runs a `--doctor` smoke test against each format in CI (#592), but if you've touched the launcher or patch surface, build locally and confirm:
-
-   ```bash
-   ./build.sh --build appimage --clean no
-   ./test-build/claude-desktop-*.AppImage --doctor
-   ```
-
-5. **The version variables are in sync.**
-
-   ```bash
-   gh variable get REPO_VERSION
-   gh variable get CLAUDE_DESKTOP_VERSION
-   grep -oP 'x64/\K[0-9]+\.[0-9]+\.[0-9]+' scripts/setup/detect-host.sh | head -1
-   ```
-
-   The grep value should match the `CLAUDE_DESKTOP_VERSION` variable. If not, pull the latest URLs from `main` — the `check-claude-version` workflow may have updated them on `main` without rebasing your branch ([`CLAUDE.md`](CLAUDE.md#common-gotchas) has the recipe).
-
-## Bumping and tagging
-
-```bash
-# 1. Bump the project version (this is a GitHub Actions variable, not a file).
-gh variable set REPO_VERSION --body "2.0.13"
-
-# 2. Tag with both versions in the tag name.
-git tag "v2.0.13+claude$(gh variable get CLAUDE_DESKTOP_VERSION)"
-
-# 3. Push the tag — this is what kicks off the release build.
-git push origin "v2.0.13+claude$(gh variable get CLAUDE_DESKTOP_VERSION)"
-```
-
-The `REPO_VERSION` variable bump can happen before or after the tag push; CI reads neither directly. The variable exists so future workflow runs know the current project version.
-
-## What CI does on tag push
-
-The [`release`](.github/workflows/ci.yml) job in `ci.yml` is gated on `startsWith(github.ref, 'refs/tags/v')`. After `test-flags`, `build-amd64`, `build-arm64`, and `test-artifacts` pass:
-
-1. Downloads all nine assets (six packages -- amd64 + arm64, each in deb/rpm/AppImage -- plus two `.zsync` delta files and a `reference-source.tar.gz`).
-2. Pulls release notes from the separate [`aaddrick/claude-desktop-versions`](https://github.com/aaddrick/claude-desktop-versions) repo if available; falls back to the autogenerated changelog otherwise.
-3. Creates the GitHub Release and attaches the nine assets.
-4. Hands off to `update-apt-repo`, `update-dnf-repo`, and `update-aur-repo`, which publish to the Cloudflare-fronted package repos ([`docs/learnings/apt-worker-architecture.md`](docs/learnings/apt-worker-architecture.md) for the redirect chain).
-
-## After the release lands
-
-- **Verify the Release page.** Nine assets attached, sizes look right, release notes rendered.
-- **Smoke-test one artifact.** Download the AppImage and run `--doctor` against it.
-- **Watch `apt-repo-heartbeat`.** The next daily run validates the redirect chain end-to-end. If it opens a tracking issue, walk the chain in [`docs/learnings/apt-worker-architecture.md`](docs/learnings/apt-worker-architecture.md#heartbeat-failure-runbook).
-
-## If something goes wrong mid-release
-
-- **Build fails.** Push the fix to `main`, then re-tag with a new `+claude` suffix (or a `+rebuild.N` suffix if upstream hasn't moved). The original tag stays — releases are append-only.
-- **A bad release shipped.** Mark the GitHub Release as a pre-release / draft and ship a follow-up. Don't delete artifacts that may already be cached by the APT/DNF Worker.
-- **The `check-claude-version` workflow conflicts with your local branch.** Pull URL changes from `main` before pushing your tag — the workflow autobumps `scripts/setup/detect-host.sh` between your work and your tag.

-# Security Policy
-
-Report suspected vulnerabilities privately via [GitHub Security Advisories](https://github.com/aaddrick/claude-desktop-debian/security/advisories/new). Do not open a public issue or post details in Discussions.
-
-## Scope
-
-This project repackages an upstream Electron app. The boundary matters:
-
-**In scope** — things this repo ships:
-
-- Patches in `scripts/patches/*.sh`
-- Packaging scripts in `scripts/packaging/`
-- The launcher (`scripts/launcher-common.sh`) and the `claude-desktop --doctor` surface
-- CI workflows under `.github/workflows/`
-- The APT/DNF Cloudflare Worker under `worker/`
-- The frame-fix wrapper and any other JS we inject into `app.asar`
-
-**Out of scope** — file upstream:
-
-- Vulnerabilities in the Claude Desktop application itself, the Anthropic API, or the claude.ai web app. Those go to Anthropic's support / disclosure channels — not here. This project can't fix them and shouldn't be the public record.
-
-## What to include in a report
-
-- Reproducer: commands, environment, distro / desktop / session type
-- Output of `claude-desktop --doctor` if relevant
-- Affected version(s) — `git describe --tags` or the release tag you installed from
-- Any related upstream CVEs or advisories you found while investigating
-
-## Response
-
-GitHub Advisories notify @aaddrick. Acknowledgement is usually within a few days. Fix turnaround depends on the surface — packaging-layer bugs are usually fast; patches against minified upstream JS may need to wait for a tractable anchor in a future upstream release.
-
-## Disclosure history
-
-Past privacy-sensitive fixes (e.g., issue-triage bot scoping, log redaction in `--doctor` output) landed through the normal PR flow with public history; there have been no embargoed disclosures to date. If that changes, this section gets entries with the advisory ID, the affected versions, and the fix.

-## Build Environment Variables
-
-The build pulls the Electron prebuilt binary from `github.com/electron/electron/releases` via `@electron/get`. Two upstream environment variables let you redirect that fetch:
-
-- `ELECTRON_MIRROR` — base URL to fetch Electron releases from instead of GitHub. Useful for mirrors or local proxies. Example: `ELECTRON_MIRROR=https://npmmirror.com/mirrors/electron/`.
-- `ELECTRON_CUSTOM_DIR` — overrides the path segment after the mirror. Defaults to `v{version}`.
-
-The cache location is fixed at `~/.cache/electron/` (resolved by `@electron/get` via `envPaths`) and is reused across builds. `ELECTRON_CACHE` is **not** read by `@electron/get` — set `ELECTRON_MIRROR` if you need to avoid the public CDN.
-
-The pinned Electron version lives in `scripts/setup/dependencies.sh` (`electron_version`) and must match `build-reference/app-extracted/package.json` — the upstream Claude Desktop `app.asar` is built against a specific Electron major and running a different one is unsupported.

+
+## Application Logs
+
+Runtime logs are available at:
+```
+~/.cache/claude-desktop-debian/launcher.log
+```
+
+## Common Issues
+
+### Window Scaling Issues
+
+If the window doesn't scale correctly on first launch:
+1. Right-click the Claude Desktop tray icon
+2. Select "Quit" (do not force quit)
+3. Restart the application
+
+This allows the application to save display settings properly.
+
+### Global Hotkey Not Working (Wayland)
+
+If the global hotkey (Ctrl+Alt+Space) doesn't work, ensure you're not running in native Wayland mode:
+
+1. Check your logs at `~/.cache/claude-desktop-debian/launcher.log`
+2. Look for "Using X11 backend via XWayland" - this means hotkeys should work
+3. If you see "Using native Wayland backend", unset `CLAUDE_USE_WAYLAND` or ensure it's not set to `1`
+
+**Note:** Native Wayland mode doesn't support global hotkeys due to Electron/Chromium limitations with XDG GlobalShortcuts Portal.
+
+See [CONFIGURATION.md](CONFIGURATION.md) for more details on the `CLAUDE_USE_WAYLAND` environment variable.
+
+### AppImage Sandbox Warning
+
+AppImages run with `--no-sandbox` due to electron's chrome-sandbox requiring root privileges for unprivileged namespace creation. This is a known limitation of AppImage format with Electron applications.
+
+For enhanced security, consider:
+- Using the .deb package instead
+- Running the AppImage within a separate sandbox (e.g., bubblewrap)
+- Using Gear Lever's integrated AppImage management for better isolation
+
+### Cowork on Ubuntu 24.04+ (AppArmor Blocks User Namespaces)
+
+Ubuntu 24.04 ships with `apparmor_restrict_unprivileged_userns=1`
+by default, which blocks the unprivileged user namespaces that
+Cowork's bubblewrap sandbox relies on. Symptoms:
+
+- `claude-desktop --doctor` reports `bubblewrap: sandbox probe failed`
+  with `Operation not permitted` in stderr.
+- `~/.config/Claude/logs/cowork_vm_daemon.log` contains
+  `bwrap is installed but cannot create a user namespace`.
+- Cowork sessions hang at "Starting VM..." or loop on reconnect.
+
+Permit user namespaces for `bwrap` via an AppArmor profile (one-time
+setup, requires sudo):
+
+```bash
+sudo tee /etc/apparmor.d/bwrap <<'EOF'
+abi <abi/4.0>,
+include <tunables/global>
+
+profile bwrap /usr/bin/bwrap flags=(unconfined) {
+    userns,
+
+    include if exists <local/bwrap>
+}
+EOF
+
+sudo apparmor_parser -r /etc/apparmor.d/bwrap
+```
+
+After applying the profile, run `claude-desktop --doctor` — the
+bubblewrap probe should pass, and Cowork should start without
+falling back to host-direct.
+
+**Security note:** this grants `/usr/bin/bwrap` the unconfined
+profile plus the `userns` capability. It matches the behavior
+bwrap had on Ubuntu 22.04 and earlier, and on most other distros,
+but is a system-wide change that affects every program invoking
+`/usr/bin/bwrap` (not just Claude Desktop). Review the profile
+against your threat model before applying.
+
+Credit: this workaround was contributed by
+[@hfyeh](https://github.com/hfyeh) in
+[#351](https://github.com/aaddrick/claude-desktop-debian/issues/351).
+
+### Cowork: "VM connection timeout after 60 seconds"
+
+If Cowork fails with a VM timeout, the KVM backend is selected but the guest VM cannot connect back to the host via vsock within the timeout window. Common causes:
+
+1. **First-boot initialization** — the guest VM may take longer than 60 seconds on first launch
+2. **vsock driver issues** — the host may be missing the `vhost_vsock` module (`sudo modprobe vhost_vsock`), or the guest initrd may lack `vmw_vsock_virtio_transport`
+
+**Fix:** Force the bubblewrap backend, which provides namespace-level isolation without a VM:
+
+```bash
+COWORK_VM_BACKEND=bwrap claude-desktop
+```
+
+See [CONFIGURATION.md](CONFIGURATION.md#cowork-backend) for how to make this permanent.
+
+### Cowork: virtiofsd not found (Fedora/RHEL)
+
+On Fedora and RHEL, `virtiofsd` installs to `/usr/libexec/virtiofsd` which is
+outside `$PATH`. The `--doctor` check detects it there automatically and will
+show `[PASS]`, but the KVM backend spawns `virtiofsd` by name at runtime and
+resolves it through `$PATH` only.
+
+**Fix:** Create a symlink so the KVM backend can find it at runtime:
+
+```bash
+sudo ln -s /usr/libexec/virtiofsd /usr/local/bin/virtiofsd
+```
+
+On Debian/Ubuntu, the same issue can occur with `/usr/lib/qemu/virtiofsd`.
+
+### Cowork: cross-device link error on Fedora tmpfs /tmp
+
+On Fedora, `/tmp` is a tmpfs by default. VM bundle downloads may fail with `EXDEV: cross-device link not permitted` when moving files from `/tmp` to `~/.config/Claude/`.
+
+**Fix:** Set `TMPDIR` to a directory on the same filesystem:
+
+```bash
+mkdir -p ~/.config/Claude/tmp
+TMPDIR=~/.config/Claude/tmp claude-desktop
+```
+
+Or add `TMPDIR=%h/.config/Claude/tmp` to the `Exec=` line in your `.desktop` file.
+
+### Authentication Errors (401)
+
+If you encounter recurring "API Error: 401" messages after periods of inactivity, the cached OAuth token may need to be cleared. This is an upstream application issue reported in [#156](https://github.com/aaddrick/claude-desktop-debian/issues/156).
+
+To fix manually (credit: [MrEdwards007](https://github.com/MrEdwards007)):
+
+1. Close Claude Desktop completely
+2. Edit `~/.config/Claude/config.json`
+3. Remove the line containing `"oauth:tokenCache"` (and any trailing comma if needed)
+4. Save the file and restart Claude Desktop
+5. Log in again when prompted
+
+A scripted solution is also available at the bottom of [this comment](https://github.com/aaddrick/claude-desktop-debian/issues/156#issuecomment-2682547498).

-Multiple session managers live inside Electron main, each
-holding its own MCP coordinator state with its own registry. The
-two that spawn stdio MCPs from `claude_desktop_config.json` and
-trigger this bug:
+Two parallel session managers live inside Electron main, each
+holding an independent Claude Agent SDK `query`:
 
 | Manager class            | IPC namespace                            | Coordinator     | Logs prefix |
 |--------------------------|------------------------------------------|-----------------|-------------|
 | `LocalSessions`          | `claude.web_$_LocalSessions_$_*`         | `n2t("ccd")`    | `[CCD]`     |
 | `LocalAgentModeSessions` | `claude.web_$_LocalAgentModeSessions_$_*`| `n2t("cowork")` | `[LAM]`     |
 
-A third coordinator class — `SshMcpServerManager` — follows the
-same per-coordinator-registry pattern but uses an SSH transport
-and doesn't contribute to the local-node double-spawn. Its
-existence does say something about the design intent: per-
-coordinator isolated state appears to be a deliberate
-architectural pattern, not a one-off oversight.
-
 The logs prefixes are what to grep `~/.config/Claude/logs/` for to
 confirm a session is hitting both coordinators (and therefore this
 bug specifically).
 
-Each coordinator dedups **within its own scope**: CCD's launch
-function serializes per server name through a promise queue and
-shuts down any prior entry before respawn; LAM's
-`getOrCreateConnection` reuses connected entries from its own
-`connections` Map. The double-spawn is strictly **cross-
-coordinator** — one process per coordinator that has the server
-in its config.
-
-In current versions (verified against `1.5354.0`) both
-coordinators route their transport creation through a shared
-Claude Desktop-side factory, but the factory itself doesn't
-dedupe and the per-coordinator registries above it aren't
-unified.
+Each `query` holds its own SDK transport. The transport's
+`spawnLocalProcess` (`Du.spawn`) launches stdio MCPs **without
+consulting the global registry** that *would* dedupe them
+(`hZ` map, accessed via `oUt(serverName)` /
+`launchMcpServer`). That registry is only used for the
+"internal" cowork in-process MessageChannelMain path.
 
 Net result: 2 coordinators × N configured MCPs = 2N processes.

-# Patching minified JavaScript
-
-Hard-won lessons from maintaining a long-lived patch suite against an
-actively re-minified upstream. Each section names a failure mode and
-the fix.
-
-The verification recipes below use claude-desktop-debian-specific
-incantations (Claude-Setup.exe, nupkg extraction, `build.sh
---build appimage`); substitute your own project's fetch/extract/build
-commands as needed.
-
-## Capturing identifiers: `\w` doesn't match `$`
-
-JS identifiers allow `$` and `_`; minifiers freely emit names like
-`$e`, `C$i`, `g$x`. The character class `\w` is `[A-Za-z0-9_]` — it
-does not match `$`. A `(\w+)` against `$e` captures the suffix `e`
-and returns a name that doesn't exist in the file. The failure is
-silent: regex matches, downstream sed runs against a truncated name,
-asar ships broken JS. Three recurrences (PRs #253, #421, #555) before
-the convention stuck.
-
-Use `[$\w]+` (repo convention; `[\w$]+` is equivalent). Strict
-superset of `\w+`, so pre-`$` versions still match. Live at
-`cowork.sh:484-502`:
-
-```bash
-const fsMatch = region.match(/([$\w]+)\.existsSync\(/);
-```
-
-## The beautified false-negative trap
-
-Testing a regex against `build-reference/` is not verification. The
-beautified copy has whitespace the regex doesn't account for.
-
-During PR #555, both `\w+` and `[\w$]+` tested false against the
-beautified file. Shipped minified bytes:
-
-```js
-await new Promise(n=>setTimeout(n,g$x))
-```
-
-Beautified copy:
-
-```js
-await new Promise((n) => setTimeout(n, g$x))
-```
-
-`await new Promise\(([\w$]+)=>\s*setTimeout\(\1,\s*([\w$]+)\)\)` fails
-the beautified version on the parens and spaces around `=>`. Always
-close the loop against shipped bytes.
-
-## Whitespace tolerance: `\s*` vs `[ \t]*`
-
-`\s` matches newlines. A `\s*`-padded pattern is a license to span
-across structural boundaries the original line layout meant to
-keep apart — usually fine on minified bytes (no newlines to span),
-much looser on beautified.
-
-Use `[ \t]*` when the intent is "spaces but stay on this line."
-Reserve `\s*` for crossing structural boundaries on purpose. The
-existing `cowork.sh` patches mix both — `\s*` where the surrounding
-context is bounded enough that newline-spanning is harmless, and
-literal token sequences (`",b:` etc.) when stricter adjacency is
-required.
-
-## Replacement-string escaping: `\1`, `&`, `$1`
-
-A regex can match correctly and still produce corrupted output
-because the *replacement string* has its own metacharacters. Match
-debugging shows green; the asar still ships broken bytes. Three
-flavors:
-
-**sed `&`** — the entire match. `sed 's/foo/&_suffix/'` is fine
-(`foo_suffix`). `sed 's/foo/literal_&_dollar/'` accidentally
-interpolates the match (`literal_foo_dollar`). Escape with `\&` if
-you want a literal ampersand:
-
-```bash
-sed 's/foo/literal_\&_dollar/'   # → literal_&_dollar
-```
-
-**sed `\1`** — backreferences in the replacement. These work as
-expected in BRE/ERE. The footgun is the *pattern* side: in BRE, `$`
-is the end-of-line anchor, so a literal `$` in the search pattern
-needs `\$`. `_common.sh:25` does exactly this for `electron_var`,
-which can be `$e` on newer upstream:
-
-```bash
-electron_var_re="${electron_var//\$/\\$}"
-```
-
-That escaping is for the sed *pattern*, not its replacement.
-
-**JS `String.prototype.replace`: `$1`, `$&`, `$$`** — the JS
-replacement DSL is its own thing. `$&` is the whole match; `$1..$9`
-are capture groups; `$$` is a literal `$`. Plain `$` followed by an
-unrelated char is left alone, but `$&` and `$N` get interpolated:
-
-```js
-code.replace(/foo/g, '$cost')   // → '$cost' (safe, no special)
-code.replace(/foo/g, '$&_x')    // → 'foo_x' ($& = match)
-code.replace(/foo/g, '$$cost')  // → '$cost' (escaped)
-```
-
-If the replacement is an injected JS snippet that happens to
-contain `$1` or `$&` (template literals, jQuery, regex source), JS
-will eat them. Use `$$` to escape, or build the string with
-concatenation so `$` never sits next to a digit or `&`.
-
-## Idempotency: a re-run must be byte-identical
-
-Without it, CI re-runs and partial builds layer mutations until
-something breaks visibly. Three patterns:
-
-**Re-key the guard to post-rename names.** `tray.sh:174-180` keys its
-fast-path guard on the post-rename
-`${tray_var}.setImage(${electron_var}.nativeImage.createFromPath(${path_var}))`
-sequence, so the second run recognizes its own first-run output.
-
-**Negative lookbehind, inline.** `cowork.sh:102-106` — the
-`(?<!...)` prevents a second match against text the first run
-already wrapped:
-
-```js
-const logRe = new RegExp(
-    '(?<!\\|\\|process\\.platform==="linux"\\))' +
-    win32Var.replace(/[.*+?^${}()|[\]\\]/g, '\\$&') +
-    '(\\s*\\?\\s*"vmClient \\(TypeScript\\)")'
-);
-```
-
-**Explicit `code.includes(...)` check.** `cowork.sh:227-230`
-separates "anchor missing" from "already applied" in the build log:
-
-```js
-} else if (code.includes(
-    'getDownloadStatus(){return process.platform==="linux"?'
-)) {
-    console.log('  Cowork auto-nav suppression already applied');
-}
-```
-
-PR #436 verified by running the patch twice and diffing the output.
-
-## Anchor selection: prefer literals over identifiers
-
-The above sections cover making a patch work on first run. This one
-covers keeping it working release after release. A patch can apply
-cleanly today and silently no-op next month.
-
-Minified identifiers churn every release. Developer strings —
-property names, log messages, IPC channel names — survive
-minification untouched (true for the upstream bundler used here; a
-`--mangle-props` build would invalidate property-name anchors).
-Anchor on those. A hardcoded minified name silently no-ops the next
-release; the build log still says "patched."
-
-Three patterns from the suite:
-
-- **Quick-window (PR #390, fixing #144).** Original patch:
-  `s/e.hide()/e.blur(),e.hide()/`. When `e` became `Sa`, it no-oped.
-  The rewrite anchors on `"pop-up-menu"` (`quick-window.sh:17`), the
-  `isWindowFocused` property name (`quick-window.sh:60`), and the
-  `[QuickEntry]` log strings (`quick-window.sh:88-91`).
-- **Cowork spawn (PR #436).** Anchored on `,VAR.mountConda)`
-  (`cowork.sh:741`) — unique to the 12-arg call path, absent from the
-  10-arg one-shot. Asserts match count is exactly 1 and bails
-  otherwise (`cowork.sh:744`), so a future second caller surfaces
-  immediately.
-- **Tray (PR #515).** `tray.sh:16` uses the literal `"menuBarEnabled"`
-  as a *position anchor*, then captures the surrounding minified
-  identifier (`\K\w+(?=\(\)\})`) as the actual patch target. Two
-  stages: stable literal → derived identifier. Every other tray name
-  chains off that single dynamic extraction.
-
-The lesson is about finding stable points to anchor on, not about
-what gets patched. The patch target is usually a minified identifier;
-the *anchor* should be a developer string nearby.
-
-## Multi-site coordinated patches: surface partial application
-
-Site 1 patches, site 2 misses, the asar ships half-wired. The
-pattern: each sub-patch sets a per-site boolean flag on success,
-then a single named WARNING fires if any flag is false:
-
-```js
-if (!siteADone || !siteBDone) {
-    console.log('  WARNING: <ticket> partial — siteA=' + siteADone +
-        ' siteB=' + siteBDone + '; <fallback consequence>');
-}
-```
-
-CI greps the build log for `WARNING:` and fails the build. That
-catches the half-patched state even when individual sub-patches each
-log "applied." See `cowork.sh:759-763` for a real instance —
-three-site `sharedCwdPath` forwarding, daemon fallback if any site
-misses.
-
-## Disambiguating non-unique anchors: lastIndexOf over indexOf
-
-A string anchor can appear in source maps, dead exports, or
-chunk-merged duplicates alongside the live code. `indexOf` returns
-the first; that may be wrong.
-
-`cowork.sh:264` uses `lastIndexOf(serviceErrorStr)` to bias toward
-appended code. On 1.5354.0 the string occurs once, so the change is
-a no-op there — the defense is for a future upstream that
-reintroduces the string in onboarding text or sample data far from
-the live retry-loop site.
-
-When neither side is reliable, narrow the search region first.
-`cowork.sh:269-276` does this for the ENOENT check, scanning only a
-300-character window before the error string.
-
-## Verifying a hypothesis before shipping a fix
-
-Pull the pinned URL and SHA from `scripts/setup/detect-host.sh`,
-download, verify hash, extract without beautifying, and test the
-regex against the minified bytes:
-
-```bash
-url=$(grep -oP "claude_download_url='\K[^']+" \
-    scripts/setup/detect-host.sh | head -1)
-expected=$(grep -oP "claude_exe_sha256='\K[^']+" \
-    scripts/setup/detect-host.sh | head -1)
-mkdir -p /tmp/verify && cd /tmp/verify
-wget -q -O Claude-Setup.exe "$url"
-echo "$expected  Claude-Setup.exe" | sha256sum -c -
-
-7z x -y Claude-Setup.exe -o exe
-nupkg=$(find exe -name 'AnthropicClaude-*.nupkg' | head -1)
-7z x -y "$nupkg" -o nupkg
-npx asar extract nupkg/lib/net45/resources/app.asar app
-
-node -e '
-  const fs = require("fs");
-  const code = fs.readFileSync(
-    "app/.vite/build/index.js", "utf8");
-  const re = /await new Promise\(([\w$]+)=>\s*setTimeout\(\1,\s*([\w$]+)\)\)/;
-  const m = code.match(re);
-  console.log(m ? `MATCH: ${m[0]}` : "NO MATCH");
-'
-```
-
-`NO MATCH` means the regex is wrong. Verifying the SHA defends against
-stale URL pinning or server-side binary swap.
-
-## End-to-end verification (post-build)
-
-Four layers: build log, syntactic validity, asar markers, runtime.
-
-1. Check the patch-count line:
-
-   ```bash
-   ./build.sh --build appimage --clean no 2>&1 | tee build.log
-   grep -E 'Applied [0-9]+ cowork patches' build.log
-   ```
-
-   Healthy 1.5354.0 build: `Applied 12 cowork patches`. A lower
-   number, or any `WARNING:` in the cowork section, is a half-patched
-   asar.
-
-2. `node --check` on the patched `index.js` — catches malformed
-   replacements that serialize but don't parse (PR #436 used this in
-   dry-run validation):
-
-   ```bash
-   node --check test-build/.../app.asar.contents/.vite/build/index.js
-   ```
-
-3. Static-grep the shipped asar for the 9 cowork markers from PR
-   #555. `scripts/verify-patches.sh` automates this (issue #559 D6)
-   and runs in CI on every `amd64-deb` build via the
-   `Verify cowork patches in shipped asar` step in
-   `.github/workflows/build-amd64.yml`. Reusable for non-cowork patch
-   sets — pass any same-shape TSV as the second arg.
-
-4. Launch the AppImage and check runtime state:
-
-   ```bash
-   tail -20 ~/.config/Claude/logs/cowork_vm_daemon.log
-   ls -la "${XDG_RUNTIME_DIR}/cowork-vm-service.sock"
-   ss -lpx | grep cowork-vm-service.sock
-   ```
-
-   Daemon log should have `lifecycle startup` and `lifecycle
-   listening`; socket should exist and be owned by the
-   `cowork-vm-service.js` process listed by `ss`.

-# Docs Style Guide
-
-How docs are organized and written in this repo. The patterns here come from a survey of well-organized open-source docs (Spatie, Filament, laravel-docs, earendil-works/pi) plus what's worked in this project's own `docs/` tree. If you're adding a page, read the **Page anatomy** section before you start.
-
-## Structure
-
-- **Flat `docs/`**, **lowercase kebab-case** filenames (`troubleshooting.md`, not `TROUBLESHOOTING.md`; `building.md`, not `BUILDING.md`). Order belongs in this index, not filenames.
-- One entry point: **[`docs/index.md`](../index.md)**. It's the GitHub-browsable landing page and the link target from every other doc.
-- **Subdirectories only when a topic grows past ~5 pages.** Current subdirs:
-  - [`docs/learnings/`](../learnings/) — subsystem deep-dives. Promoted out of the top level once there were >3.
-  - [`docs/testing/`](../testing/) — test harness docs.
-  - [`docs/issue-triage/`](../issue-triage/) — the issue-triage bot config and prompts.
-  - [`docs/upstream-reports/`](../upstream-reports/) — bug reports filed against upstream that we keep alongside the patch.
-  - `docs/styleguides/` — meta-docs about how to write docs and shell scripts.
-- **`docs/images/`** for screenshots and diagrams. Never scatter `.png`s next to `.md`s.
-- **Repo-root auxiliary files stay at the root** so GitHub auto-detects them: `README.md`, `CHANGELOG.md`, `CONTRIBUTING.md`, `SECURITY.md`, `LICENSE-*`, `RELEASING.md`, `CLAUDE.md`, `AGENTS.md`. Don't move them under `docs/`.

-## Page anatomy
-
-Three skeletons recur across well-organized docs in this project. Pick one before starting a page.
-
-### Setup / how-to page
-
-Used for: `building.md`, `configuration.md`, `releasing.md` (in the root).
-
-```
-<one declarative sentence: what this page is for>
-<one code block showing the minimum working command>
-## Prerequisites          -> short list; assume Linux + git unless stated
-## <Step 1>               -> one short paragraph + code block
-## <Step 2>
-## Common variations      -> distro-specific or flag-specific quirks
-## Troubleshooting        -> link out to troubleshooting.md, don't duplicate
-```
-
-Open with the minimum command, not the prerequisites table. Readers skim to the code block first.
-
-### Troubleshooting / FAQ page
-
-Used for: `troubleshooting.md`.
-
-```
-<one declarative sentence: what kind of problem this page solves>
-## <Symptom or error message verbatim>    -> one ### Fix per symptom, with a code block
-## <Next symptom>
-```
-
-The headings are **the symptom users type into search.** Don't editorialize ("Troubles with Wayland" is wrong — `## Black screen on Fedora KDE under Wayland` is right). One `### Fix` per `##`. If a symptom needs explanation, prose goes under the fix, not in the heading.
-
-### Subsystem deep-dive (a "learning")
-
-Used for: everything in `docs/learnings/`.
-
-```
-<one paragraph: what subsystem this covers, when it runs, why it's non-obvious>
-**Source files:** bullet list of GitHub links to the relevant source
-## Overview                -> 2–3 paragraphs of context
-## <Mechanic>              -> for each non-trivial mechanic, prose + diagram only when state transitions need one
-## <Failure mode>          -> for each known failure, repro + diagnosis + fix path
-## References              -> issues, PRs, upstream bugs, useful commits
-```
-
-Deep-dives can be long — `apt-worker-architecture.md` and `patching-minified-js.md` are >10 kB and that's fine. They serve repeat readers (future you, future contributors) hunting for a specific fact, not first-timers.

-## Content rules
-
-1. **Open every page with one declarative sentence, then a code block or list.** No "In this guide we will explore…" preamble. If the page is in the root (not behind `[< Back to ...]`), the first line under the H1 is that sentence.
-2. **Imperative, second-person, present tense.** "Run the build." Not "users may wish to consider running the build."
-3. **Domain nouns.** This is a packaging project — use `patches`, `the launcher`, `the worker`, `app.asar`, `the minified bundle`, `the asar archive`. Don't say `foo`/`bar` in end-to-end recipes. Placeholders are tolerable in basic-usage; in walkthroughs they kill comprehension.
-4. **Real PR / issue / commit references over hand-waving.** "Fixed in [#475](https://github.com/aaddrick/claude-desktop-debian/pull/475)" beats "fixed in a recent PR." `git log --grep` works on links; not on adjectives.
-5. **Defaults first, then the override.** "The build auto-detects your distro. To force a format, pass `--build appimage`."
-6. **Warnings in alert blocks**, not paragraphs: `> [!NOTE]`, `> [!WARNING]`, `> [!TIP]`. GitHub renders them; reading them isn't optional.
-7. **Source-file blocks on deep-dives.** Bulleted GitHub links to the actual files. Don't bury source references in prose.
-8. **Cross-link liberally.** Every page should link to 2–4 others. `docs/index.md` should link to every page in `docs/`.
-9. **One file per topic.** Don't paste the same config block into three pages. Show it once in `configuration.md`; excerpt subsections elsewhere with a link back.
-10. **Rationale lives in `decisions.md` or a learning**, not sprinkled through feature docs. If you find yourself writing "we did this because…" in a how-to page, that paragraph belongs in `learnings/<topic>.md` or `decisions.md`.
-
-## Patterns worth stealing
-
-- **Comparison tables for near-synonyms.** When something has overlapping siblings (deb vs. rpm vs. AppImage vs. nix; Wayland vs. XWayland; SUID sandbox vs. user namespaces), a `| feature | A | B | C |` table beats three prose paragraphs.
-- **"Source files" block at the top of deep-dives.** See [`docs/learnings/apt-worker-architecture.md`](../learnings/apt-worker-architecture.md) for the canonical example.
-- **`[< Back to <parent>]` link at the top of subpages.** GitHub doesn't render breadcrumbs; this is the manual equivalent. Use it on pages inside subdirectories.
-- **Verbatim error messages as `##` headings in `troubleshooting.md`.** Users land via search; search hits the heading.
-
-## Antipatterns
-
-- **Duplicating quickstart in three places.** README is pitch + install one-liner + link to docs. Real install lives in `building.md`, and only there.
-- **`docs/` without an `index.md`.** GitHub renders an alphabetical file list and contributors get lost.
-- **Uppercase / SHOUTY filenames** (`TROUBLESHOOTING.md`). Hard to type, looks dated, inconsistent with `docs/learnings/*.md`. Lowercase kebab-case throughout.
-- **Numbered prefixes** (`01-introduction.md`). Order belongs in `index.md`. Renumbering rots cross-links.
-- **Free-form FAQ prose** ("Q: How do I…? A: Well, you might…"). Use `## <error message>` → `### Fix` → code instead. Search ranks headings, not paragraphs.
-- **One page past ~30 kB that isn't a reference/deep-dive.** Promote to a subdirectory or split. CLAUDE.md is the exception — it's an archaeology document, not a how-to.
-- **Inline "this changed in v2.0.7" annotations** scattered through current docs. Version notes belong in `CHANGELOG.md`.
-- **Code blocks without a "when to use this" sentence above them.** Turns docs into a man-page dump.
-- **Hiding `CONTRIBUTING.md` or `SECURITY.md` under `docs/`.** GitHub stops auto-detecting them.

+# docs/testing/cases grounding sweep — implementation prompt
+
+This file is meant to be **copied verbatim into a fresh Claude Code
+session** as the initial user message. Don't paraphrase it; the
+orchestration depends on the exact directives below.
+
+---
+
+## Prompt to paste
+
+You're picking up after the v7 walker, U01 wire-up, and the
+`claudeai.ts` AX-tree migration all landed. The page-objects are
+stable against the live renderer (T17_folder_picker passes on
+KDE-W). The next workstream is **grounding the case docs in
+`docs/testing/cases/` against actual upstream behavior**.
+
+The cases were written from outside-in — observed user-visible
+flows, expected outcomes, diagnostic captures. Many describe
+behavior the test author *believed* exists in upstream Claude
+Desktop, but no one has cross-checked each Step / Expected against
+the actual extracted source. Your job is to spawn one subagent per
+case file, have each one read the case + grep the build-reference
+extract for the relevant feature, and report what's accurate, what's
+stale, and what's missing — then make in-place adjustments to the
+case files so each one is grounded in concrete code anchors before
+the next sweep cycle.
+
+### Authoritative reference
+
+Read these in order. They're the substrate the subagents will pull
+from.
+
+- `docs/testing/cases/README.md` — the case-doc structure (severity,
+  surface, applies-to, steps, expected, diagnostics, references).
+  The "Standard test body" template at the bottom is the contract
+  every case currently follows.
+- `docs/testing/matrix.md` — live Pass/Fail/Pending matrix per row.
+  Tells you which cases have a runner and which are still
+  human-execution-only.
+- `build-reference/app-extracted/.vite/build/` — the extracted +
+  beautified Claude Desktop source. ~14 files; `index.js` is the
+  main process (~546k lines after beautification), `mainView.js` /
+  `mainWindow.js` / `quickWindow.js` are renderer preloads,
+  `coworkArtifact.js` is the cowork BrowserView preload,
+  `buddy.js` is the supervisor, etc. **This is the ground truth.**
+- `tools/test-harness/src/runners/` — existing runners that *do*
+  have working selectors / event hooks. Sometimes the runner has
+  more accurate code anchors than the case doc.
+- `CLAUDE.md` (project root) — project conventions, attribution
+  format, commit style. Don't violate.
+
+### Case files in scope
+
+Eleven files plus the README. One subagent per file:
+
+| File | Tests covered |
+|---|---|
+| `code-tab-foundations.md` | T15-T20 |
+| `code-tab-handoff.md` | T23-T25, T34, T38, T39 |
+| `code-tab-workflow.md` | T21-T22, T29-T32 |
+| `distribution.md` | S01-S05, S15, S16, S26 |
+| `extensibility.md` | T11, T33, T35-T37, S27, S28 |
+| `launch.md` | T01, T02, T13, T14 |

+| `routines.md` | T26-T28, S19-S21 |
+| `shortcuts-and-input.md` | T05, T06, S06-S14, S29-S37 |
+| `tray-and-window-chrome.md` | T03, T04, T07, T08, S08, S13 |
+
+### Why this iteration
+
+Several cases have been silently bit-rotting against upstream
+changes — a Step says "click the X menu" but X was renamed two
+upstream versions ago, or an Expected references a behavior the
+team shipped behind a feature flag that's now off by default. When
+the sweep runs against a row that's stale, the failure looks like a
+Linux compatibility issue but is actually a doc-vs-upstream drift.
+Grounding the cases against the actual extracted source closes
+that gap and makes future sweeps interpretable.
+
+This isn't a one-time correctness pass — it's a cycle. After every
+upstream version bump (`CLAUDE_DESKTOP_VERSION` rolls in
+`scripts/setup/detect-host.sh`), the grounding can drift again.
+Optimise for **leaving concrete code-anchor breadcrumbs** in each
+case so the next grounding pass is fast.
+
+### Repo conventions
+
+- Tabs for indentation in code; markdown is space-indented as the
+  existing files do it.
+- Markdown lines wrap at ~80 chars unless they're tables or links
+  that don't break naturally.
+- Don't commit. The user reviews and commits.
+- Don't run the host Claude Desktop. The user runs it. Read from
+  `build-reference/` instead — that's already extracted +
+  beautified specifically so you don't have to attach to a live
+  app to verify behavior.
+
+### Code anchors
+
+- `build-reference/app-extracted/.vite/build/index.js` — main
+  process. Every IPC channel registration, window-management
+  decision, app-lifecycle hook, tray-menu construction, autostart
+  toggle, dialog invocation, and protocol handler lives here.
+- `build-reference/app-extracted/.vite/build/quickWindow.js` —
+  Quick Entry preload + window setup.
+- `build-reference/app-extracted/.vite/build/mainWindow.js` —
+  main shell BrowserWindow preload (claude.ai is loaded into a
+  child BrowserView; this preload runs in the shell frame).
+- `build-reference/app-extracted/.vite/build/mainView.js` —
+  preload running inside the claude.ai BrowserView itself.
+- `build-reference/app-extracted/.vite/build/coworkArtifact.js` —
+  preload running inside cowork's iframe-shaped artifact view.
+- `build-reference/app-extracted/.vite/build/buddy.js` — supervisor
+  process (the daemon that respawns the cowork worker; see
+  `docs/learnings/cowork-vm-daemon.md`).
+- `build-reference/app-extracted/package.json` — declared main /
+  preloads, electron version, native deps. Quick reference for
+  whether a feature is wired up at all.
+
+### Phases
+
+#### Phase 0 — calibration
+
+1. `cd tools/test-harness && npm run typecheck` — should pass; if
+   not, stop and report.
+2. Read `docs/testing/cases/README.md` end-to-end and one full case
+   file (suggest `launch.md` — small, four tests, easy
+   surface-area). Confirm you understand the case-doc contract
+   before fanning out.
+3. Pick T01 (App launch) as a calibration case. Manually grep
+   `build-reference/app-extracted/.vite/build/index.js` for the
+   launcher-log / backend-selection logic referenced in T01's
+   Expected. Confirm you can read the beautified source and locate
+   the relevant code. Report the anchor (`index.js:N-M`) so the
+   user knows the workflow is sound before you fan out.
+
+If Phase 0 surfaces a problem (build-reference stale relative to
+the case doc, calibration anchor not findable, README structure
+unclear), stop and report. Don't fan out subagents against an
+unverified workflow.
+
+#### Phase 1 — fan-out
+
+Spawn one subagent per case file (eleven total). Use
+`subagent_type: 'general-purpose'`. Send them in **parallel** —
+they're independent. Keep the prompt to each subagent
+self-contained; the subagent has no context from this conversation.
+
+Per-subagent prompt template (fill in the case file path):
+
+```
+You're grounding ONE test-case file in
+docs/testing/cases/<FILE>.md against the extracted Claude Desktop
+source at build-reference/app-extracted/.vite/build/.
+
+Read these first:
+- docs/testing/cases/README.md (case-doc contract)
+- docs/testing/cases/<FILE>.md (your case file)
+- CLAUDE.md (project conventions)
+
+For each test in the file:
+
+1. Read the test's Steps + Expected.
+2. Identify the load-bearing claim — the upstream behavior the
+   test depends on (an IPC channel, a tray-menu item, a
+   dialog.showOpenDialog call, a globalShortcut.register, a
+   nativeTheme listener, etc.).
+3. Grep build-reference/app-extracted/.vite/build/ for that claim.
+   Use ripgrep / grep -E. The code is beautified but minified
+   variable names — anchor on string literals, IPC channel names,
+   menu labels, event names, not variable identifiers.
+4. Classify the result:
+   - **Grounded** — claim verified, anchor found. Append a
+     `**Code anchors:** <file>:<line>` line to the test body
+     directly under the existing References field.
+   - **Drifted** — feature exists but the case's Steps or Expected
+     don't match what's actually shipping. Edit the case to
+     match upstream behavior. Note what changed.
+   - **Missing** — feature isn't in the build at all (deprecated,
+     never shipped, behind unset flag). Mark the test with a
+     prepended block:
+     `> **⚠ Missing in build 1.5354.0** — <one-line note>. Re-verify after next upstream bump.`
+   - **Ambiguous** — claim could be one of several upstream code
+     paths and you can't disambiguate from the case alone. Don't
+     edit; report under "Open questions".
+
+Per-test, prefer concrete code anchors over wordy explanations.
+The next person reading this case should see exactly where
+upstream implements the feature.
+
+Constraints:
+- Don't fabricate anchors. If you can't find it, mark Missing or
+  Ambiguous — never invent a `index.js:12345` reference.
+- Don't restructure the case files. Keep the existing template
+  (Severity / Surface / Applies to / Issues / Steps / Expected /
+  Diagnostics / References). Only add code anchors and edit
+  Steps/Expected for drift.
+- Don't expand scope. If you notice an unrelated bug or missing
+  test, note it under "Open questions" — don't fix it inline.
+- Don't run the host Claude Desktop. Read from build-reference/
+  only.
+
+Report shape (~300-500 words):
+
+## <FILE>.md grounding
+
+- Tests reviewed: N
+- Grounded: N
+- Drifted (edited): N (one-line per: <test-id> — <what changed>)
+- Missing (marked): N (one-line per: <test-id> — <what's gone>)
+- Ambiguous (flagged): N (one-line per: <test-id> — <why>)
+
+### Code anchor highlights
+- <test-id>: <file>:<line> — <what the anchor proves>
+
+### Open questions
+- ...
+
+### Files touched
+- docs/testing/cases/<FILE>.md
+```
+
+Keep the report tight. The orchestrator reads eleven of these and
+synthesizes.
+
+#### Phase 2 — synthesis
+
+Once all eleven subagents return:
+
+1. Aggregate per-classification counts across all files. Big
+   numbers in any column are signals:
+   - Lots of **Drifted** → upstream had a recent feature shuffle;
+     the team should know.
+   - Lots of **Missing** → either the case doc was written
+     speculatively or upstream removed features without telling.
+   - Lots of **Ambiguous** → the case-doc template needs a
+     "Implementation hint" field so future grounding has a
+     starting point.
+2. Cross-check: did any subagent edit the same anchor differently?
+   (Unlikely since each owns one file, but worth a sanity pass.)
+3. Check that `git diff docs/testing/cases/` matches what the
+   subagents reported. If a subagent claimed Drifted but didn't
+   write to disk, surface it.
+4. Build the user-facing summary (see "Final report format" below).
+
+Don't make the user re-read the eleven subagent reports — give
+them the synthesised view + the per-file links.
+
+### Self-correction loop
+
+After Phase 1 returns:
+
+1. If any subagent failed (no report, error, hit token limit),
+   re-spawn just that one with a tighter scope (e.g. "process
+   tests T15-T17 only, not the full file").
+2. If a subagent's report claims edits but `git diff` shows no
+   changes, the subagent silently dropped the writes — re-spawn
+   with explicit instruction to use the Edit tool.
+3. If two subagents flag the same upstream code path with
+   contradictory claims (one says Grounded, one says Missing),
+   re-read the source yourself and adjudicate.
+
+Cap re-spawns at **2 per file** — past that, mark the file as
+"needs human review" in the final report and move on.
+
+### Termination conditions
+
+Stop and write a final report when one of:
+
+1. **All eleven files grounded.** Per-file classification counts +
+   diff stat. Done.
+2. **Hit the re-spawn cap on 3+ files.** Stop, write up which
+   files are blocked, what each blocker looks like.
+3. **Build-reference is stale.** If multiple subagents report
+   "Missing" against features the user knows shipped, the
+   extract may be out of date — verify the version
+   (`build-reference/app-extracted/package.json` `version` field
+   vs `CLAUDE_DESKTOP_VERSION` repo variable) before continuing.
+
+### What you should NOT do
+
+- Don't commit. The user reviews everything.
+- Don't restructure the case-doc template. Eleven files, one
+  shape — keep it that way.
+- Don't add new tests. Grounding is a verify-and-anchor pass, not
+  a coverage expansion.
+- Don't run the host Claude Desktop. The build-reference extract
+  exists specifically so you don't have to attach to a live app.
+- Don't edit anything outside `docs/testing/cases/`. If you find
+  a runner discrepancy (case says "click X", runner clicks "Y"),
+  flag it under Open questions; don't edit the runner.
+- Don't invent anchors. If the grep doesn't find the literal,
+  classify Missing or Ambiguous — never write a fictional
+  `index.js:12345` reference.
+
+### Final report format
+
+```markdown

+
+### Operational notes
+
+- Subagents are launched in parallel via a single message with
+  multiple Agent tool calls. Don't serialize them — Phase 1 takes
+  ~15 minutes serial, ~3 minutes parallel.
+- Each subagent's Edit calls land directly in the working tree.
+  No merge conflicts because each owns one file.
+- The build-reference `index.js` is 546k lines. Subagents should
+  use `grep -nE` with anchored string literals, not full reads.
+  Recommended grep pattern style:
+  `grep -nE 'globalShortcut\.register\([^)]*' build-reference/app-extracted/.vite/build/index.js`
+- If a subagent needs to verify a renderer-side claim (DOM event
+  flow, React component shape), the relevant preload is in
+  `mainView.js` / `mainWindow.js`. Don't grep `index.js` for
+  renderer-only behavior.
+
+Begin with Phase 0. Don't fan out until calibration succeeds.

+# lib/claudeai.ts AX-tree migration — implementation prompt
+
+This file is meant to be **copied verbatim into a fresh Claude Code
+session** as the initial user message. Don't paraphrase it; the
+self-correction loop depends on the exact directives below.
+
+---
+
+## Prompt to paste
+
+You're picking up after the v7 fingerprint walker + U01 wire-up
+landed. Walker, resolver, and U01 are all on the AX-tree substrate.
+The page-object library `tools/test-harness/src/lib/claudeai.ts` is
+still on the old substrate — `document.querySelector` against
+minified-tailwind class shapes (`button[aria-haspopup="menu"]` +
+`span.truncate.max-w-[Npx]`) — and that's where every claude.ai UI
+spec couples to upstream's React DOM. Your job is to migrate the
+brittle CSS-shape walks in `claudeai.ts` to AX-tree resolution using
+the v7 walker primitives, run the H/S spec families that consume
+them, and iterate until those specs pass without DOM-shape coupling.
+
+### Authoritative reference
+
+Read these in order. They contain the design, the gotchas, and the
+runtime contract — the prompt below assumes them as background.
+
+- `docs/testing/fingerprint-v7-plan.md` — design contract for the v7
+  fingerprint, kind-strictness matrix, resolver fallback chain. Skim
+  the "Capture algorithm" and "Resolver / fallback chain" sections;
+  the migration consumes the same primitives.
+- `docs/learnings/test-harness-ax-tree-walker.md` — the five
+  non-obvious AX-tree traps (AX-enable async lag, navigateTo no-op,
+  flat dialog>button[] lists, more-options shape, sidebar
+  virtualization). All apply here too — `lib/claudeai.ts` calls run
+  inside the same renderer the walker drives.
+- `tools/test-harness/src/lib/claudeai.ts` — the migration target.
+  ~340 lines, eight functions plus two classes (`CodeTab`,
+  `LocalEnvPill`). Every public function is a discovery walk against
+  `evalInRenderer` with `document.querySelectorAll`.
+
+### Why this iteration
+
+Per the v7 plan's design goal §2 "Resilient to cosmetic drift" —
+upstream regenerates tailwind class signatures on rebuild
+(`max-w-[Npx]`, `df-pill`-style atoms), so `claudeai.ts`'s CSS-shape
+walks break on any minor UI rebuild even when the AX-computed role
+and accessible name are stable. The U01 wire-up confirmed the AX
+tree is a usable substrate end-to-end (~7s/test, 89/90 stable across
+two consecutive sweeps). Pulling `claudeai.ts` onto the same
+substrate eliminates the recurring "tailwind regen breaks H05/S31
+again" failure mode.
+
+Acceptance per the plan: H05 + S29-S37 + T-prefix specs that consume
+`claudeai.ts` keep passing on the same account, with zero new
+flakes. Migration is mechanical (replace the eval-string walks with
+AX-tree queries) and the existing tests are the contract.
+
+### Repo conventions
+
+- Tabs for indentation, lines under 80 chars, single quotes for
+  literals, TypeScript strict mode (`tools/test-harness/tsconfig.json`
+  enforces it).
+- Comments only when the WHY is non-obvious — write the `because:`
+  clause, not the `that:` clause.
+- No backward-compatibility shims. If a function's signature needs
+  to change, change every caller. Don't keep both code paths.
+- Don't commit. The user reviews and commits.
+
+### Code anchors
+
+- `tools/test-harness/explore/walker.ts` — exports the primitives
+  you'll consume:
+  - `findByFingerprint(inspector, fingerprint, kind)` — full
+    resolver with strictness gating + relaxed-scope fallback.
+    Overkill for one-shot lookups against the live renderer.
+  - `queryAccessibleTree(elements, query)` — pure filter, used at
+    capture and resolve time. Takes a `RawElement[]` snapshot and
+    an `AxQuery` (ariaPath + leaf criteria). What you'll likely
+    wrap.
+  - `axTreeToSnapshot(nodes)` — converts CDP `AxNode[]` to the
+    walker's `RawElement[]` shape. Drops ignored nodes.
+  - `walkLandmarkAncestors(raw)` — emits the AriaStep[] for an
+    element. Useful if a method needs to disambiguate by landmark.
+  - `waitForAxTreeStable(inspector, opts)` — gating primitive used
+    by walker + U01. Use `{ minNodes: 1, timeoutMs: 10000 }` for
+    post-click reads (matches `snapshotSurface`'s default).
+- `tools/test-harness/src/lib/inspector.ts` — `getAccessibleTree`
+  fetches the raw CDP tree filtered to the claude.ai webContents.
+- `tools/test-harness/src/lib/claudeai.ts` — the migration target.
+  Read the file-header comment first; it documents the discovery
+  strategy you're replacing.
+- `tools/test-harness/src/runners/H05_ui_drift_check.spec.ts`,
+  `S31_quick_entry_submit_reaches_new_chat.spec.ts`,
+  `S32_quick_entry_submit_gnome_stale_isfocused.spec.ts` — primary
+  consumers of the methods being migrated.
+
+### Phases
+
+#### Phase A — spike on one method
+
+1. `cd tools/test-harness && npm run typecheck` — must pass before
+   doing anything.
+2. Pick `openPill(inspector, labelPattern, opts)` as the spike.
+   It's the most CSS-shape-coupled method and exercises the
+   menu-render polling pattern the rest of `claudeai.ts` reuses.
+3. Replace its body with an AX-tree query:
+   - Fetch the AX tree (`inspector.getAccessibleTree('claude.ai')`),
+     convert via `axTreeToSnapshot`.
+   - Filter to elements with `computedRole === 'button'` and
+     accessibleName matching `labelPattern`.
+   - For each candidate, compute its parent landmark via
+     `walkLandmarkAncestors`. The compact-pill discriminator —
+     "has a `span.truncate.max-w-[Npx]` child" — needs an AX
+     analogue. Most likely: parent is `toolbar` / `group` and the
+     element has `aria-haspopup === 'menu'` (exposed in AX as
+     `hasPopup` property; check whether `RawElement` carries it
+     and extend if needed).
+   - Click via `inspector.clickByBackendNodeId(raw.backendDOMNodeId)`.
+   - Poll for menu items via AX role match (`menuitem`,
+     `menuitemradio`, `menuitemcheckbox`).
+4. Run H05 against your branch (`./node_modules/.bin/playwright
+   test src/runners/H05_ui_drift_check.spec.ts`). H05 doesn't
+   directly call `openPill` but exercises the same renderer state;
+   if H05 regresses your AX walk is wrong.
+5. Run S31 (`./node_modules/.bin/playwright test
+   src/runners/S31_quick_entry_submit_reaches_new_chat.spec.ts`).
+   This calls `openPill` indirectly via `CodeTab.activate` →
+   `findCompactPills`.
+6. If both pass, the AX substrate works for at least one method.
+   Commit the shape mentally (don't `git commit` — the user does
+   that). If either fails, the spike is in trouble; re-read the
+   AX-tree learnings doc for traps you missed and fix the
+   primitive before expanding.
+
+#### Phase B — migrate the rest
+
+For each remaining function in `claudeai.ts`, port the discovery
+walk to AX:
+
+- `activateTab(inspector, name)` — `button` with
+  `accessibleName === name` under root or banner landmark. Existing
+  `aria-label="X"` selector → AX `name` literal match.
+- `findCompactPills(inspector)` — list of buttons with
+  `hasPopup === 'menu'` AND inner `span.truncate.max-w-[…]` text
+  child. AX equivalent: button role + hasPopup + a child
+  `genericContainer` (or whatever AX exposes for `<span>`) carrying
+  the visible text. Returns `{text, maxW, expanded}` today —
+  `maxW` is a tailwind artifact and should be dropped from the AX
+  shape (callers don't use it for matching, just for diagnostics;
+  keep a placeholder or remove from the type).
+- `clickMenuItem(inspector, textPattern, opts)` — element with
+  role in `{menuitem, menuitemradio, menuitemcheckbox}` and
+  accessibleName matching `textPattern`. The CSS attribute selector
+  has an AX direct equivalent.
+- `pressEscape(inspector)` — keep as-is. It's a keydown dispatch,
+  not a discovery walk.
+- `CodeTab.activate(opts)` — calls `activateTab` + polls
+  `findCompactPills`. Migrates by transitivity.
+- `LocalEnvPill` — read its body to enumerate callers.
+
+After each migration:
+1. `npm run typecheck` — must pass.
+2. `npx tsx explore/walker.ts` — selfTest must pass (you may have
+   touched walker.ts to expose new primitives).
+3. Run the affected spec(s).
+
+#### Phase C — full sweep
+
+1. Run all H/S/T runners that consume `claudeai.ts`:
+   - H05 (UI drift)
+   - S31 (Code-tab submit)
+   - S32 (GNOME stale isFocused)
+   - any T-prefix that uses `installOpenDialogMock` or `pressEscape`
+2. Tally pass/fail. The post-migration baseline must equal the
+   pre-migration baseline, modulo flakes characterized in
+   `docs/learnings/test-harness-ax-tree-walker.md`.
+
+Cap iterations at **5 sweep cycles** total (spike + 4 fix-rerun
+cycles) — past that, stop and report.
+
+##### Failure classes
+
+1. **AX-shape mismatch.** Element has the CSS shape the old code
+   relied on but a different AX role/name than expected. Fix:
+   probe the AX tree for the actual shape (use
+   `inspector.getAccessibleTree('claude.ai')` interactively from a
+   one-shot script), update the AX query.
+2. **Missing AX property exposure.** `hasPopup`, `expanded`, etc.
+   may not be in `RawElement` today (the walker only reads role,
+   name, ancestors, sibling info). Extend `RawElement` and
+   `axTreeToSnapshot` to expose what the migration needs. Update
+   walker.ts selfTest if you change the snapshot shape.
+3. **Race against menu render.** Old code polled
+   `document.querySelectorAll('[role=menuitem]')` every 50ms. AX
+   tree updates lag DOM by hundreds of ms; bake a
+   `waitForAxTreeStable({ minNodes: 1 })` between click and
+   menuitem fetch instead of a short DOM poll.
+4. **Tailwind-class diagnostic loss.** `findCompactPills` returns
+   `maxW` which callers use only in error messages. If the
+   AX-only return shape drops `maxW`, error messages get less
+   informative — accept it, don't reintroduce DOM walks just for
+   diagnostics. Keep the `maxW` field optional/null in the type.
+
+##### What "fix" means
+
+A fix is one of:
+- A code change in `claudeai.ts`, `walker.ts`, or `inspector.ts`.
+- A targeted extension of `RawElement` / `axTreeToSnapshot` to
+  expose an AX property the migration needs.
+
+Not a fix:
+- `// eslint-disable-next-line` / `// @ts-ignore` / `as unknown as ...`.
+- Keeping the old `document.querySelector` walk as a fallback.
+- Adding an AX walk that wraps a CSS walk that wraps an AX walk.
+
+### Self-correction loop (general protocol)
+
+After each phase's specific loop:
+
+1. If `npm run typecheck` reports errors, fix root causes — no
+   `// @ts-ignore`, no `any`, no `as unknown as ...`.
+2. If `npx tsx explore/walker.ts` (selfTest) fails, the change broke
+   an algorithmic invariant. Don't relax the test; fix the change.
+3. **Cap fix attempts per problem class at 3.** After 3 attempts
+   on the same class without progress, stop and report.
+4. Mark Phase complete only when every step in that Phase passes
+   cleanly.
+
+### Termination conditions
+
+Stop and write a final report when one of:
+
+1. **Migration is clean.** All `claudeai.ts` methods on AX
+   substrate, all consuming specs pass at the pre-migration
+   baseline. Report final pass tallies + diff stat.
+2. **Hit the 5-sweep cap.** Report what's done, what's blocked,
+   and what each remaining failure looks like.
+3. **Hit the 3-attempt cap on a non-trivial issue.** Report
+   attempts, why each failed, what's blocked.
+4. **AX exposure gap.** A claude.ai surface uses a property the AX
+   tree doesn't expose (e.g., custom `data-state` attributes
+   without a corresponding ARIA reflection). Stop, document the
+   gap, ask the user before adding a hybrid AX+DOM walk.
+
+### What you should NOT do
+
+- Don't commit. The user reviews everything.
+- Don't keep both substrates. The migration is atomic per method:
+  CSS walk out, AX walk in. No fallback chains.
+- Don't add new abstractions in `claudeai.ts` that aren't required
+  by the migration. The file's shape (one function per UI verb) is
+  load-bearing for callers — don't introduce a `PageObject` base
+  class or a generic AX builder.
+- Don't run the host Claude Desktop. The user runs it. The H/S
+  specs use `launchClaude` with `seedFromHost` or `null` isolation
+  per spec — confirm with the user before any sweep.
+- Don't widen `RawElement` speculatively. Only add fields the
+  migration consumes. Each new field bloats every snapshot.
+- Don't drill into a single-method workaround that other methods
+  would have to duplicate. If a fix wants to live in a helper,
+  put it next to `queryAccessibleTree` in `walker.ts`.
+
+### Final report format
+
+```markdown

+- Functions migrated:    N / N
+- Walker.ts changes:     <one-line summary>

+
+### Operational notes
+
+- Background runs: use `Bash run_in_background: true` for any
+  multi-spec sweep, and `Monitor` with a tight grep filter
+  (`✓|✘|Error|FAIL|EXIT=`) to stream events. Stop the monitor when
+  the run completes.
+- Check for leftover Electron processes between runs
+  (`pgrep -af '/usr/lib/claude-desktop/node_modules/electron'`)
+  and stale tmpdirs (`ls /tmp/claude-test-*`) — clean both up if
+  the prior run errored before teardown.
+- The U01 wire-up landed two `walker.ts` fixes that are part of
+  the substrate you're inheriting:
+  1. `findByFingerprint`: strictness gate also defers to
+     `fingerprint.classification === 'instance'` for degenerate
+     fingerprints.
+  2. `redrivePath`: navigates to startUrl when current URL drifted;
+     reloads only when already at startUrl.
+  Both are live in the working tree (or just-merged main,
+  depending on when this prompt fires).
+
+Begin with Phase A. Read `claudeai.ts` end-to-end first — in
+particular the file-header discovery comment (lines 1-31) and the
+`openPill` body (lines 162-202) — so you understand what the
+existing CSS-shape walks are anchoring on before you replace them.

+# claude.ai UI Map
+
+*Last updated: 2026-05-02*
+
+This file is the index from "UI surface" → "test-harness abstraction." It
+answers: *which renderer surface does each Layer-2 helper cover, and where
+are the gaps?* For human-readable behavior and visual specs of each surface
+(what each button looks like, what each menu does), see [`ui/`](./ui/).
+For the architectural rationale and growth strategy of the wrapper, see
+[`claudeai-ui-mapping-plan.md`](./claudeai-ui-mapping-plan.md).
+
+A `✓` marker means the helper exists today, with a `file:line` reference
+into [`tools/test-harness/src/lib/claudeai.ts`](../../tools/test-harness/src/lib/claudeai.ts).
+A `TODO` marker is a planned helper — when a third test needs the same
+shape, promote it from inline `evalInRenderer` to a top-level helper or
+page-object method (see plan Phase 3).
+
+## Top-level routes
+
+- `/new` — chat composer page (default landing for signed-in users)
+- `/chat/<uuid>` — open chat session
+- `/epitaxy` — Code tab landing
+- `/projects/<id>` — project view
+- `/login`, `/auth/*` — pre-login routes (test harness skips here)
+
+The Code df-pill click does **not** change the URL — the router rerenders
+the tab body inline. Helpers must poll for body-mount signals (e.g. a
+compact pill rendering) rather than waiting on navigation.

+
+- Open Quick Entry (global shortcut) — covered by `lib/quickentry.ts`
+- Compose + send — covered by `lib/quickentry.ts`
+- Closeout cases (S29–S37) — covered by `lib/quickentry.ts`
+
+### Notifications
+
+UI reference: [`ui/notifications.md`](./ui/notifications.md). libnotify
+rendering is environmental — likely stays a manual checklist rather than
+a renderer-side helper. No `claudeai.ts` coverage planned.
+
+### Tray
+
+UI reference: [`ui/tray.md`](./ui/tray.md). Tray is owned by the main
+process / native bindings, not the renderer DOM — outside the scope of
+`claudeai.ts`. Covered by separate tests (T03, S08).
+
+## Atoms inventory
+
+Stable structural patterns the lib already anchors on. See the
+discovery comment at the top of
+[`tools/test-harness/src/lib/claudeai.ts`](../../tools/test-harness/src/lib/claudeai.ts)
+for why each is shape-matched rather than class-matched.

+| compact-pill | `button[aria-haspopup=menu] > span.truncate.max-w-[*]` | `findCompactPills` (:130), `openPill` (:162) |
+| menu / menuitem | `[role=menu] [role=menuitem*]` | `clickMenuItem(regex)` (:210) |

+| Electron `dialog.showOpenDialog` | main-process IPC | `installOpenDialogMock` (:70), `getOpenDialogCalls` (:113) |
+
+Atoms not yet abstracted (when a third test needs the same shape,
+promote to a top-level helper):
+
+| Atom | Probable fingerprint | Status |
+|---|---|---|
+| modal | `[role=dialog]` | not seen yet |
+| toast | `[role=status][aria-live]` | not seen yet |

+# claude.ai UI Mapping Plan
+
+This is an executable plan for systematically mapping claude.ai's
+renderer UI into reusable test-harness abstractions. It can be picked
+up by a fresh session — start at "Phase 1" and walk down.
+
+## Where we are
+
+The harness already has one worked example: `tools/test-harness/src/lib/claudeai.ts`
+exports a `CodeTab` class plus atom helpers (`activateTab`,
+`installOpenDialogMock`, `findCompactPills`, `openPill`, `clickMenuItem`,
+`pressEscape`). `T17_folder_picker.spec.ts` is its only consumer
+today — drives the chain `Code df-pill → env pill → Local → Select
+folder → Open folder` and asserts `dialog.showOpenDialog` fires.
+
+Discovery evidence captured by `tools/test-harness/probe.ts` (run
+against a live debugger on port 9229):
+
+- df-pill is a stable atom — exactly 3 instances on Code-tab page
+  (`Chat`, `Cowork`, `Code`), all with `class*="df-pill"` and
+  matching `aria-label`.
+- compact-pill is a stable atom — `button[aria-haspopup=menu]` with
+  a `span.truncate.max-w-[Npx]` child. Env pill uses 200px,
+  Select-folder pill uses 160px. Same Tailwind class signature; we
+  anchor on structure, not classes.
+- 80 `button[aria-haspopup=menu]` total on a Code-tab page; only the
+  2 with the truncate fingerprint are pills, the other 78 are sidebar
+  "More options" buttons.
+
+Pattern proven: discovery-by-shape in the lib layer, page-object
+classes per major UI surface, specs use the lib. This doc covers
+how to extend that pattern across the rest of claude.ai.
+
+## Strategy: three layers
+
+**Layer 1 — atoms.** Generic helpers around stable structural
+patterns. Live in `lib/claudeai.ts`. Built once, reused everywhere.
+Examples already there: compact-pill, df-pill, menu, dialog mock.
+
+**Layer 2 — page objects.** Domain classes per major UI surface
+(CodeTab, ChatTab, Settings, etc.). Compose atoms. Built per test
+demand — premature otherwise. CodeTab is the template.
+
+**Layer 3 — discovery tooling.** Standalone scripts that connect to
+a running debugger and let humans + agents explore the renderer.
+`probe.ts` is the seed; this doc grows it into a small CLI.
+
+The thing to avoid: comprehensively mapping the UI upfront. Even
+with a recording tool, that burns time on surfaces no test will
+exercise for months. Lazy + bookmark-the-shape wins.
+
+## Phase 1 — Tooling foundation
+
+**Goal:** turn `probe.ts` into a proper exploration CLI under
+`tools/test-harness/explore/`, with snapshot + diff capability that
+catches UI drift before tests do.
+
+**Deliverables:**
+
+- `tools/test-harness/explore/explore.ts` — entry point with
+  subcommands.
+- `tools/test-harness/explore/snapshot.ts` — capture renderer state.
+- `tools/test-harness/explore/diff.ts` — compare two snapshots.
+- `tools/test-harness/explore/find.ts` — search for elements.
+- `docs/testing/ui-snapshots/` — directory for captured snapshots
+  (gitignore the file contents but commit the directory + a README).
+- `tools/test-harness/package.json` — add scripts:
+  `npm run explore`, `npm run explore:snapshot <name>`, etc.
+
+**Subcommand spec:**
+
+```
+npx tsx explore/explore.ts                  # full snapshot to stdout
+npx tsx explore/explore.ts pills            # df-pills + compact-pills + state
+npx tsx explore/explore.ts menu             # currently-open menu structure
+npx tsx explore/explore.ts snapshot <name>  # write to docs/testing/ui-snapshots/<name>.json
+npx tsx explore/explore.ts diff <a> <b>     # diff two snapshots — flags renamed/removed
+npx tsx explore/explore.ts find <regex>     # search renderer for matching text/aria-label
+```
+
+Snapshot shape (per file):
+
+```json
+{
+  "capturedAt": "2026-05-02T17:30:00Z",
+  "claudeAiUrl": "https://claude.ai/epitaxy",
+  "appVersion": "1.1.7714",
+  "dfPills": [...],
+  "compactPills": [...],
+  "ariaLabeledButtons": [...],
+  "openMenu": null,
+  "modals": [...]
+}
+```
+
+`diff` should flag: removed elements (selector → no match), changed
+text/aria-label, new elements (informational, not a failure). Output
+human-readable + a `--json` flag for machine consumption.
+
+**How to dispatch this work:**
+
+Single agent, `general-purpose`. Brief:
+
+> Build the explore CLI under `tools/test-harness/explore/`. Read
+> `tools/test-harness/probe.ts` as the seed implementation. Match the
+> existing project style (tabs, multi-line `//` why-blocks, terse).
+> Reuse `src/lib/inspector.ts` (`InspectorClient.connect(9229)`) for
+> the debugger connection. Subcommands as specified in
+> `docs/testing/claudeai-ui-mapping-plan.md` Phase 1. Do not delete
+> probe.ts — leave it as a one-off; it can be removed in a follow-up.
+> Typecheck with `npx tsc --noEmit` (no test runs). Add npm scripts
+> to `package.json`. Add a thin README in
+> `docs/testing/ui-snapshots/README.md` explaining how to capture +
+> compare snapshots.
+
+**Exit criteria:**
+
+- `npx tsx explore/explore.ts pills` against a running debugger lists
+  the 3 df-pills and 2 compact-pills (or whatever's on screen).
+- `explore/explore.ts snapshot baseline-code-tab` writes a JSON file.
+- `explore/explore.ts diff baseline-code-tab baseline-code-tab`
+  reports zero diffs.
+- Typecheck green.
+
+## Phase 2 — UI map document
+
+**Goal:** maintain a living markdown index of every reachable UI
+surface, the navigation path to reach it, and which Layer-2 class
+covers it (or `TODO` if none yet).
+
+**Deliverable:** `docs/testing/claudeai-ui-map.md`.
+
+**Initial content** (populate from what's known today, leave gaps
+marked TODO):
+
+```markdown
+# claude.ai UI Map
+
+Source of truth for "where does each UI surface live, and which
+test-harness abstraction covers it." Update as new abstractions are
+added.
+
+## Top-level routes
+
+- `/new` — chat composer page (default landing for signed-in users)
+- `/chat/<uuid>` — open chat session
+- `/epitaxy` — Code tab landing
+- `/projects/<id>` — project view
+- `/login`, `/auth/*` — pre-login routes (test harness skips here)
+
+## Surfaces by tab
+
+### Chat (df-pill "Chat", route /new)
+- Composer textarea — TODO `ChatTab.composer()`
+- "+" submenu (Add files / Add to project / Skills / Connectors / ...)
+  — TODO `ChatTab.openAttachMenu()`
+- Model selector — TODO
+- Stop / regenerate — TODO
+
+### Cowork (df-pill "Cowork")
+- Workspace list — TODO
+- Environment switcher — TODO
+
+### Code (df-pill "Code", route /epitaxy)
+- Env pill (Local / Cloud / SSH) — `lib/claudeai.ts:CodeTab.openEnvPill()` ✓
+- Select folder pill — `lib/claudeai.ts:CodeTab` (used internally by
+  `openFolderPicker`) ✓
+- Folder picker dialog — `lib/claudeai.ts:installOpenDialogMock` ✓
+- File tree (left panel) — TODO
+- Editor pane — TODO
+
+## Surfaces independent of tab
+
+### Sidebar
+- Search — TODO `SidebarNav.search()`
+- Recent conversations — TODO `SidebarNav.openRecent(idx | uuid)`
+- "More options" per row — TODO
+- New session button — TODO
+
+### Native dialogs
+- File / folder picker — `lib/claudeai.ts:installOpenDialogMock` ✓
+- Message box / confirm — TODO `installShowMessageBoxMock`
+- Save dialog — TODO `installShowSaveDialogMock`
+
+### Menus / popovers
+- Generic menu open + click — `lib/claudeai.ts:openPill` /
+  `clickMenuItem` ✓
+- Modal — TODO `Modal.dismiss() / Modal.confirm()`
+- Toast / status — TODO `waitForToast(regex)`
+
+### Settings
+- Hotkey rebind — TODO
+- Theme toggle — TODO
+- Account / sign-out — TODO
+
+## Atoms inventory
+
+Stable structural patterns the lib already anchors on:
+
+| Atom | Fingerprint | Helper |
+|---|---|---|
+| df-pill | `button[aria-label][class*="df-pill"]` | `activateTab(name)` |
+| compact-pill | `button[aria-haspopup=menu] > span.truncate.max-w-[*]` | `findCompactPills`, `openPill` |
+| menu / menuitem | `[role=menu] [role=menuitem*]` | `clickMenuItem(regex)` |
+
+Atoms not yet abstracted (when a third test needs the same shape,
+promote to a top-level helper):
+
+| Atom | Probable fingerprint | Status |
+|---|---|---|
+| modal | `[role=dialog]` | not seen yet |
+| toast | `[role=status][aria-live]` | not seen yet |
+| sidebar nav row | `[class*="df-row"] [aria-label]` | seen, not abstracted |
+| chat composer | textarea/contenteditable in composer container | not abstracted |
+```
+
+**How to dispatch this work:**
+
+A claude-code-guide or general-purpose agent can write the initial
+file. Single message:
+
+> Create `docs/testing/claudeai-ui-map.md` matching the structure in
+> `docs/testing/claudeai-ui-mapping-plan.md` Phase 2. Pull TODO
+> entries from the planned ChatTab/Settings/etc. surfaces. Mark
+> existing helpers from `tools/test-harness/src/lib/claudeai.ts`
+> with ✓ and the file:line. Don't run any tests.
+
+**Exit criteria:**
+
+- File exists with all top-level routes documented.
+- Every existing `lib/claudeai.ts` export is referenced ✓.
+- Every planned surface from this plan has a TODO entry.
+
+## Phase 3 — Page objects per test demand
+
+**Goal:** add new Layer-2 classes (ChatTab, Settings, etc.) when the
+first test needs them. Don't speculate.
+
+**Template:** `tools/test-harness/src/lib/claudeai.ts:CodeTab`. Match
+its shape:
+
+- Instance class taking `inspector: InspectorClient` in constructor.
+- Public methods are either single-step (`openEnvPill`,
+  `selectLocal`) or multi-step convenience (`openFolderPicker`).
+- Discovery by shape, not Tailwind classes.
+- Multi-line `//` why-block at top of class explaining what UI
+  surface it covers and the discovery strategy.
+- Failures throw with enough context for the spec to attach to
+  `testInfo.attach()`.
+
+**Workflow per new page object:**
+
+1. Identify which test motivates the new class. Don't build
+   speculatively.
+2. Run `explore.ts snapshot <name>` against a live debugger on the
+   target UI surface. Commit the snapshot under
+   `docs/testing/ui-snapshots/`.
+3. Inspect the snapshot — pick stable structural fingerprints, not
+   Tailwind classes.
+4. Write the class in `lib/claudeai.ts`. If the file gets large
+   (>1500 lines), split per-tab into separate files
+   (`lib/claudeai/code-tab.ts`, `lib/claudeai/chat-tab.ts`, with
+   `lib/claudeai.ts` as the barrel).
+5. Update `docs/testing/claudeai-ui-map.md` — replace the TODO with
+   the class name + ✓.
+6. Add the spec that uses it.
+7. Run typecheck. Don't run tests until everything's wired.
+
+**Don't pull out yet:**
+
+- Single-consumer methods. If only one spec calls
+  `Settings.toggleDarkMode()`, the inline implementation is fine.
+  Promote to its own method when a second consumer arrives.
+- Generic primitives that haven't repeated three times. Three is
+  the threshold for "this is an atom" — two could still be
+  coincidence.
+
+## Phase 4 — Atom promotion
+
+**Goal:** keep the atom layer (Layer 1) growing in step with the
+page-object layer (Layer 2).
+
+**Rule:** when a discovery pattern (CSS selector + JS predicate)
+appears in 3 different page objects, promote it to a top-level
+helper in `lib/claudeai.ts`.
+
+**Examples of likely promotions in the next 6 months:**
+
+- `findModal()` / `dismissModal()` — every page object that opens a
+  confirmation modal will need this.
+- `waitForToast(regex, timeout)` — error and success toasts are
+  pervasive.
+- `installShowMessageBoxMock(inspector, response)` — for native
+  confirm dialogs.
+- `clickNavRow(label)` — sidebar interactions.
+
+**Process:**
+
+1. Notice the third occurrence of the same pattern.
+2. Move the inline implementation up to a top-level export.
+3. Replace the three call sites with calls to the new export.
+4. Add an entry to the atoms inventory in `claudeai-ui-map.md`.
+
+## Phase 5 — Drift detection
+
+**Goal:** catch UI changes that break selectors *before* a sweep
+fails — fast, automatic, runs on every harness invocation.
+
+**Deliverable:** `tools/test-harness/src/runners/H05_ui_drift_check.spec.ts`.
+
+**Design:**
+
+- Loads each `*.json` file from `docs/testing/ui-snapshots/`.
+- Connects to a running app via the existing `launchClaude` +
+  `attachInspector` flow (NOT against an externally-running app —
+  the harness must be self-contained).
+- For each snapshot, navigates to the captured URL (if not already
+  there), then asserts each captured selector still resolves to an
+  element with the same text/aria-label.
+- Failures are *attachments*, not full failures — the spec passes
+  if ≥80% of snapshots match, surfaces the diffs as warnings. Hard
+  threshold can be tightened later. Goal is "tell me what drifted,"
+  not "block CI on every minor renderer change."
+
+**How to dispatch:**
+
+Single agent, after Phases 1–2 are done. Brief:
+
+> Create `tools/test-harness/src/runners/H05_ui_drift_check.spec.ts`
+> per the design in `docs/testing/claudeai-ui-mapping-plan.md`
+> Phase 5. Read each `*.json` under `docs/testing/ui-snapshots/`,
+> drive the renderer to the captured URL, assert each captured
+> element selector still matches. Surface diffs via
+> `testInfo.attach`. Pass if ≥80% match. Severity Should, surface
+> "claude.ai UI drift detection". Typecheck only.
+
+**Exit criteria:**
+
+- Runs cleanly against current renderer state (all snapshots match).
+- Returns ≤200ms per snapshot.
+- Skip with a clear message when no signed-in host config available
+  (most snapshots will be of post-login surfaces).
+
+## Recommended order
+
+1. **Phase 1 (tooling)** — ~2 hours, single agent. Foundation for
+   everything else.
+2. **Phase 2 (UI map doc)** — ~30 min, single agent. Cheap,
+   self-documenting.
+3. **Phase 3 (page objects)** — incremental, per test need.
+4. **Phase 4 (atom promotion)** — opportunistic, no scheduled work.
+5. **Phase 5 (drift detection)** — once Phase 1 is done and a few
+   snapshots exist.
+
+Phases 1 and 2 are independent and can run in parallel.

+# Fingerprint v7 Plan — Contextual, Account-Portable Identification
+
+This is an executable plan for the v6 → v7 migration of the inventory
+fingerprint shape used by `tools/test-harness/explore/walker.ts` and
+`tools/test-harness/src/runners/U01_ui_visibility.spec.ts`. It can be
+picked up by a fresh session — start at "Phase 1" and walk down.
+
+## Where we are
+
+`docs/testing/ui-inventory.json` v6 (captured 2026-05-03 against app
+1.5354.0, 383 entries) records each interactive element with a
+fingerprint of this shape:
+
+```ts
+fingerprint: {
+  selector: 'button[aria-label="Search"]',
+  ariaLabel: 'Search',
+  role: null,
+  tagName: 'BUTTON',
+  textContent: null,
+}
+```
+
+`U01` resolves entries by handing the `selector` field to Playwright.
+The current scheme has three load-bearing failure modes:
+
+1. **Account-specific names baked into selectors and IDs.** Entries
+   like `root.button.awaaddrick-max` (the user's plan badge,
+   `button:has-text("AWAaddrick·Max")`) hardcode the walker-author's
+   username + plan tier. Any contributor running U01 against their
+   own auth fails this entry on selector match — the element is
+   structurally present, just labeled differently.
+2. **Instance text in selectors of "stable" entries.** Search-result
+   options, recent-conversations buttons, and pinned conversations
+   carry titles like "Fine-tuning diffusion models with reinforcement
+   learning" in their selectors. These are inherently per-account; the
+   `kind: instance` taxonomy already exists to handle them, but the
+   selector still encodes the literal title, so the v6 capture
+   couldn't actually leverage `instance` semantics.
+3. **Selector brittleness under cosmetic redesigns.** `button:has-text(...)`
+   selectors break under any label change. `button[aria-label="..."]`
+   selectors break under any aria-label rewrite (which the upstream
+   team does for accessibility audits without warning). Neither
+   strategy carries enough redundancy to recover when one signal drifts.
+
+The reconciliation doc (`ui-inventory-reconciliation.md`) flags these
+as "Walker coverage gap" and "Account-state-dependent" categories,
+and the U01 brief lists per-user inventory regeneration as "a
+separate workstream." This is that workstream.
+
+## Design goals
+
+In priority order:
+
+1. **Account-portable.** A v7 inventory walked against User A's
+   account matches against User B's renderer for any entry whose
+   target element is structurally present in both accounts. Entries
+   that genuinely don't exist in B's account fall back to the existing
+   "skip if absent" semantics (`kind: instance` + ancestor-presence
+   check).
+2. **Resilient to cosmetic drift.** Label changes, aria-label
+   rewrites, minified-class churn, and CSS rewrites must not
+   invalidate the fingerprint when the element's semantic role and
+   structural position survive.
+3. **Surface drift before failure.** Soft drift (primary aria-path
+   missed, relaxed-scope match recovered) attaches a warning to the
+   test rather than passing silently. Hard drift (no strategy
+   resolves) fails as today. The sweep gains a third state:
+   `passed-with-drift`.
+4. **Atomic cutover, not gradual migration.** v7 walker, v7 inventory
+   schema, and v7 resolver land together. The committed v6 inventory
+   gets invalidated the moment v7 walker ships; no parallel-emit
+   compatibility window, no `legacy` selector fallback in the
+   resolver. Two systems are worse than one.
+
+Non-goals:
+
+- Pixel-level visual diff. Separate concern; H05 is the right shape.
+- AI / embedding-based matching. Out of scope for a Linux repackager.
+- Behavioral fingerprints (click-and-verify-effect). Too expensive at
+  383 entries.
+
+## v7 schema
+
+```ts
+interface FingerprintV7 {
+  // Primary: accessibility-tree path from nearest landmark down to
+  // the leaf. Each step carries (role, optional name).
+  ariaPath: AriaStep[];
+
+  // The element itself. Drops `name` entirely when role + ariaPath
+  // suffice for uniqueness on the captured surface.
+  leaf: {
+    role: string;                     // "button", "link", "menuitem", ...
+    name: NameMatcher | null;
+    siblingIndex: SiblingIndex | null;
+  };
+
+  // Stability classification — drives how strictly the resolver
+  // matches. See "Kind-strictness matrix" below. Distinct from the
+  // existing `kind` field (persistent / structural / menu / instance)
+  // which captures *lifecycle*, not *match strictness*.
+  classification: 'stable' | 'positional' | 'instance';
+}
+
+interface AriaStep {
+  role: string;          // landmark / region / grouping role
+  name: NameMatcher | null;  // optional — only included when needed
+}
+
+type NameMatcher =
+  | { kind: 'literal'; value: string }       // "Search", "Cowork"
+  | { kind: 'pattern'; regex: string };      // "\\w+·(Free|Pro|Max|...)"
+
+interface SiblingIndex {
+  role: string;          // role of siblings being indexed
+  position: number;      // 0-based
+  total: number;         // total siblings of that role at capture
+}
+```
+
+## Capture algorithm
+
+Run during walker.ts's element emission, after the surface has settled.
+
+```text
+captureFingerprint(element, surface):
+  ariaPath = walkLandmarkAncestors(element)
+    // Stop at <body>; emit a step for each role in
+    // {banner, main, navigation, region, complementary,
+    //  contentinfo, search, form, toolbar, menu, menubar,
+    //  listbox, list, dialog, tablist, tabpanel, group}
+    // with grouping role plus optional accessible name.
+
+  role = element.role
+  name = element.accessibleName
+
+  // Step 1: try uniqueness without the name.
+  matches = surface.queryAccessibleTree({
+    ariaPath,
+    leaf: { role }
+  })
+  if matches.length == 1:
+    return { ariaPath, leaf: { role, name: null, siblingIndex: null },
+             classification: 'stable' }
+
+  // Step 2: still too broad — try the name as a discriminator,
+  // shaping it if it looks instance-specific.
+  classification = classifyName(name, surface)
+  if classification != 'instance':
+    nameMatcher = (classification == 'positional')
+      ? null
+      : (looksInstanceShaped(name)
+          ? { kind: 'pattern', regex: shapeOfName(name) }
+          : { kind: 'literal', value: name })
+    matches = surface.queryAccessibleTree({
+      ariaPath, leaf: { role, name: nameMatcher }
+    })
+    if matches.length == 1:
+      return { ariaPath, leaf: { role, name: nameMatcher,
+               siblingIndex: null },
+               classification }
+
+  // Step 3: still ambiguous — fall through to sibling position.
+  siblings = element.parent.childrenWithRole(role)
+  if siblings.length > 1:
+    siblingIndex = {
+      role,
+      position: siblings.indexOf(element),
+      total: siblings.length
+    }
+    return { ariaPath, leaf: { role, name: null, siblingIndex },
+             classification: 'positional' }

+```
+
+`queryAccessibleTree` should hit `Accessibility.getFullAXTree` over
+CDP, not the DOM. The accessibility tree is what screen readers see
+and what the platform APIs query — it's the substrate that aria
+roles and accessible names actually live in.
+
+## Name classifier
+
+`classifyName(name, surface)` decides whether a name is `stable`,
+`instance`, or `positional` (no usable name). Heuristics in priority
+order:
+
+```text
+1. Empty / whitespace name      → 'positional'
+2. Element is a list-row child  → 'instance'  (handled by ancestor
+   role: option/listitem inside listbox/list)
+3. Name matches a known
+   instance-shape regex          → 'instance'  (record as pattern)
+4. Name is in the corpus of
+   "stable UI vocabulary"        → 'stable'
+5. Default                       → 'stable' but flag for review
+```
+
+### Known instance-shape regexes
+
+| Regex | Example match | Shape recorded |
+|---|---|---|
+| `/^.+·(Free\|Pro\|Max\|Team\|Enterprise)$/` | `AWAaddrick·Max` | `\\w+·<PLAN>` |
+| `/^Opus \d/` `/^Sonnet \d/` `/^Haiku \d/` | `Opus 4.7Adaptive` | model-name passthrough (stable across users, just versioned) |
+| `/\d{1,3}%$/` | `Usage: plan 11%` | `Usage: plan \d+%` |
+| `/Today\|Yesterday\|\d+ (day\|hour\|minute)s? ago/` | `Today+12` | `<RELATIVE-DATE>(\\+\d+)?` |
+| `/^\d+\.\d+ \w+/` | `1.5 GB` | `\d+\.\d+ \w+` |
+| `/@\w+/` | `@aaddrick` | `@\w+` (treat as user-handle) |
+| `/[A-Z][a-z]+ [A-Z][a-z]+ [a-z]/` (3+ word title-case) | `Fine-tuning diffusion models...` | treat as `'instance'`, no pattern |
+
+These regexes live in a registry that's part of the v7 capture
+config. Adding a new shape is a one-file change; the registry should
+be ordered (first match wins) so specific patterns take precedence
+over general ones.
+
+### Building the stable UI vocabulary
+
+After the walker finishes the BFS, run a second pass:
+
+1. Collect every `accessibleName` from every captured element.
+2. Bucket by `kind` (existing taxonomy).
+3. Names appearing in 3+ entries with `kind: persistent` or
+   `kind: structural`, across 2+ surfaces, are **stable**.
+4. Names appearing in only 1 entry with `kind: persistent`/`structural`
+   are **suspect** — flag for human triage during reconciliation.
+5. Names in `kind: instance` entries are excluded from the corpus
+   entirely.
+
+Commit the resulting vocabulary list to
+`docs/testing/ui-vocabulary.json` so future walks can use it without
+re-deriving. Refresh the vocabulary on each major upstream release.
+
+## Kind-strictness matrix
+
+The existing `kind` field (`persistent` / `structural` / `menu` /
+`instance`) tunes how strictly the resolver matches at runtime,
+independently from the capture-time `classification`:
+
+| kind | aria-path required | name required | siblingIndex strict | assertion |
+|---|---|---|---|---|
+| `persistent` | yes (deepest scope) | matcher must hit if present | yes | exactly 1 match |
+| `structural` | yes (or 1 step shallower) | matcher OR position | flexible (±1 ok) | exactly 1 match |
+| `menu` | yes, scoped to transient menu surface | literal text fallback ok | n/a | ≥1 match |
+| `instance` | yes (closest list/listbox ancestor) | ignored | ignored | ≥1 match within scope |
+
+Examples:
+
+- `root.button.search` → `kind: persistent`, `classification: stable`,
+  `name: null` (unique by ariaPath alone). Strict 1-match assertion.
+- `root.button.awaaddrick-max` → `kind: persistent`, `classification: stable`,
+  `name: { kind: 'pattern', regex: '\\w+·(Free|Pro|Max|...)' }`.
+  Plan-shape pattern; user-portable.
+- `root.button.search.option.untitled-conversationtoday+12` →
+  `kind: instance`, `classification: instance`, no name, scoped to
+  search-results listbox. Assert ≥1 option in listbox.
+- `root.button.fine-tuning-diffusion-models-with-reinforcement-learning` →
+  `kind: instance`, scoped to pinned-conversations list. Assert ≥1
+  button in pinned list.
+
+## Resolver / fallback chain
+
+In `findByFingerprint`:
+
+```text
+resolve(fp):
+  // Strategy 1 — primary: full aria-tree path
+  result = tryAriaTreeMatch(fp.ariaPath, fp.leaf, fp.kind)
+  if result.matched: return { found: true, strategy: 'aria-tree' }
+
+  // Strategy 2 — relaxed aria scope (drop deepest landmark step
+  // in the path; keep the rest). Catches the common case where the
+  // upstream team adds or removes one container layer.
+  if fp.ariaPath.length > 1:
+    result = tryAriaTreeMatch(fp.ariaPath.slice(0, -1), fp.leaf, fp.kind)
+    if result.matched: return {
+      found: true, strategy: 'aria-tree-relaxed', drift: 'scope-shifted'
+    }
+
+  return { found: false, strategy: null }
+```
+
+When `drift` is set, attach a soft warning to the Playwright test
+without failing it:
+
+```ts
+testInfo.attach('drift-warning', {
+  body: JSON.stringify({
+    entryId: entry.id,
+    expected: fp.ariaPath,
+    matchedVia: result.strategy,
+    drift: result.drift,
+    note: 'primary aria-tree match failed; recovered via fallback. ' +
+          'Re-walk inventory before drift compounds.',
+  }, null, 2),
+  contentType: 'application/json',
+});
+```
+
+CI exposes `drift-warning` as a separate counter alongside pass /
+fail. Sweep summary becomes `383 passed, 12 with drift, 0 failed`.
+
+## Migration plan
+
+The cutover is atomic — no parallel-emit window. Walker, schema, and
+resolver all flip from v6 to v7 in the same merge. The committed v6
+inventory becomes invalid; first action after merge is a re-walk.
+
+### Phase 1 — vocabulary scaffold (pre-walker)
+
+The name classifier needs a stable-UI vocabulary corpus to
+disambiguate suspect names from known-stable copy. Build it from the
+existing v6 inventory before the walker rewrite:
+
+1. Iterate `docs/testing/ui-inventory.json` v6.
+2. Names appearing in 3+ entries with `kind: persistent` or
+   `kind: structural`, across 2+ surfaces, are **stable**.
+3. Names matching any registry regex (plan badge, model version,
+   percentage, relative date, user handle) are **instance-shaped**.
+4. Names appearing in only 1 entry, not matching a regex, not in
+   `kind: instance` — flag for human triage.
+5. Commit the resulting corpus to `docs/testing/ui-vocabulary.json`.
+
+The corpus survives the walker rewrite — it's keyed on names, not on
+v6 schema specifics.
+
+### Phase 2 — walker rewrite
+
+1. Add `Accessibility.getFullAXTree` query to walker's surface-settle
+   step (or AX subtree at target node if full-tree latency is
+   unacceptable; see open questions).
+2. Implement `walkLandmarkAncestors`, `queryAccessibleTree`,
+   `captureFingerprint` per the algorithm above.
+3. Implement the name classifier consuming `ui-vocabulary.json` and
+   the instance-shape registry.
+4. Replace v6 fingerprint emit with v7. Inventory schema header bumps
+   to `walkerVersion: 7`; v6 readers will fail loudly rather than
+   silently mis-resolve.
+5. Walker passes that fail to compute a v7 fingerprint (AX query
+   error, accessible-name-computation failure) emit the entry with
+   `classification: 'positional'` and `name: null`, scoped to its
+   ariaPath. Uncaptured fingerprints are not silently dropped — they
+   become positional entries with explicit looseness.
+
+Acceptance: a walk against the v6-author's account produces v7
+fingerprints for ≥98% of the surfaces v6 captured. ≥80% have
+`classification: 'stable'`; the rest split between `'positional'` and
+`'instance'`.
+
+#### Live-walk shakedown (post-Phase 2)
+
+The first end-to-end walks against the running renderer surfaced five
+real bugs the synthetic selfTest couldn't see. All landed in
+`walker.ts` / `name-classifier.ts` / `inspector.ts`:
+
+1. **AX-tree settle gate.** `Accessibility.enable` populates the tree
+   asynchronously; the existing `waitForStable` (1.5s ceiling on
+   DOM-mutation quiescence) returned long before claude.ai's React
+   tree mounted. Seed snapshots came back with 4 AX nodes (just the
+   `RootWebArea` + a generic shell) and the walker emitted zero
+   entries. Fix: `waitForAxTreeStable(inspector, { minNodes: 20 })`
+   polls `getFullAXTree` until two consecutive reads return the same
+   node count. Called once before the seed snapshot and once after
+   each `navigateTo` in `redrivePath`. Baked into every
+   `snapshotSurface` call too (with `minNodes: 1`) so post-click
+   reads don't race the React update.
+2. **`reloadPage` in `redrivePath`.** `navigateTo(url)` short-circuits
+   when `currentUrl === url`, but every BFS pop re-navigates to
+   `startUrl`, so any state a prior drill left behind (open dialog,
+   expanded sidebar, scrolled focus) carried into the next redrive
+   and contaminated `clickById`'s snapshot. Replaced the redrive's
+   initial `navigateTo` with `location.reload()` to discard the
+   React tree.
+3. **List-row sibling-count heuristic.** The plan's `isListRowChild`
+   check requires `option/listitem` inside `listbox/list`. claude.ai
+   exposes the marketplace dialog as `dialog > button[]` with no
+   list role at all (~80 cards) and the cowork sidebar as
+   `complementary > button[]` (72 sessions). Without a heuristic,
+   each row literal-matches by name and emits as a separate stable
+   entry. Extension: `LIST_ROW_ROLES` includes `button`,
+   `LIST_ANCESTOR_ROLES` includes `group`, AND `siblingTotal >= 15`
+   on its own qualifies regardless of ancestor role. Step 3
+   (positional fallback) also gates on `!isListRowChild` so list
+   rows fall through to step 4's `instance` collapse instead of
+   fragmenting into per-index positionals.
+4. **Two new instance shapes** in `name-classifier.ts`:
+   `cowork-session` matches status-prefixed session titles
+   (`^(Idle|Ready|Working|Awaiting input|Pull request merged|Done|Failed|Cancelled)\s`)
+   and `row-more-options` matches per-row triggers
+   (`^More options for `). Both ordered before `long-title` so the
+   pattern wins over the no-pattern instance fallback.
+5. **Lookup-failure threshold bump** 25 → 75. Sidebar virtualization
+   means the AX tree exposes a slightly different subset of cowork
+   sessions on each fresh load; redrives accumulate
+   "no element matches" misses in a row that aren't a real wedge.
+   The timeout counter (5 strikes) still gates against actual
+   renderer hangs.
+
+Result on the AX migration's first clean walk
+(`startUrl: claude.ai/epitaxy`, account: aaddrick, app 1.5354.0):
+**90 entries** (37 persistent / 37 structural / 8 dialog / 8
+instance), 6 denylisted, 23 non-fatal lookup misses. The marketplace
+dialog folded to a single `button-instance+704`; the cowork sidebar
+to `button-instance+72`; search history to `option-instance+25`.
+Acceptance criteria from §Phase 2 met (≥98% structural overlap is
+trivially true on a re-walk; ≥80% stable hit at 75/90 ≈ 83%).
+
+### Phase 3 — resolver rewrite (U01 + walker.ts findByFingerprint)
+
+1. Replace `findByFingerprint` body with the two-strategy chain
+   (primary aria-tree, relaxed-scope fallback). Drop the v6
+   selector code path entirely.
+2. `gen-render-specs.ts` regenerates U01 from the v7 inventory; per-
+   entry test bodies consume `entry.fingerprint` (now v7-shaped)
+   directly.
+3. Add the `drift-warning` attachment shape to U01's test runner.
+4. Run U01 against the v7 inventory captured in Phase 2; baseline
+   drift counts.
+
+Acceptance: U01 against a fresh walker pass produces 0 drift
+warnings on the same account, fails 0 entries. Drift warnings only
+appear when actually-drifted elements are encountered.
+
+### Phase 4 — account-portability validation
+
+1. A second contributor walks their own v7 inventory.
+2. Diff against the v6-author's v7 inventory: structural overlap
+   should be ≥80% on `kind: persistent` and `kind: structural`
+   entries (the cross-user-stable subset).
+3. Run the v6-author's inventory's U01 against the second
+   contributor's renderer (with `seedFromHost` lifting their auth).
+4. Expect ≥80% pass on the cross-user-stable subset; `kind: instance`
+   entries pass via the ancestor-presence check.
+
+This is the actual goal. If account-portability hits, the inventory
+is no longer a "my-account snapshot" but a true render contract.
+
+## Open questions
+
+### Resolved
+
+- **CDP `Accessibility.getFullAXTree` cost.** Not a bottleneck. The
+  signed-in `claude.ai/epitaxy` surface returns a 817-node tree;
+  `waitForAxTreeStable` settles in <1s once Chromium has populated
+  it. The cold-load gate dominates total latency, not per-call
+  overhead. Plan B (subtree queries at the target node) is unused.
+- **Role overrides.** Confirmed working. `Skip to content` on
+  claude.ai is captured as `link` (its AX-computed role) regardless
+  of the underlying tag — a class of mismatch the v6 DOM walker
+  silently got wrong.
+- **`account-bound` kind.** Not needed. The combination of
+  shape-patterned name matchers (plan badge, cowork session) +
+  the sibling-count list heuristic + persistent collapse handles
+  every account-shaped element observed in the first clean walk.
+  Re-evaluate if a future surface exposes account state without
+  one of those signals.
+
+### Open
+
+- **Accessible-name computation parity.** Chrome's AX-tree-computed
+  name should match what Playwright's `getByRole({ name })` matches
+  at resolution time, but they're independent implementations of
+  the ARIA name-computation spec. Validate at Phase 3 acceptance
+  with a sample of 50 entries — capture vs resolve should agree.
+- **Stale vocabulary across releases.** When upstream renames
+  "Cowork" to "Workspaces" (hypothetical), the corpus needs to
+  update. Should vocabulary be re-derived automatically on each walk
+  (cheap, drift-following) or pinned to a committed version (stable,
+  manual updates)? Provisionally: re-derive on walk, commit the
+  derived corpus alongside the inventory so reconciliation can diff
+  vocabulary changes.

+## Minimum viable kill-set
+
+If the goal is the smallest pass that justifies closing all three issues:
+
+- **GNOME-W** — must pass QE-2/3/4/6/7/8/9/11 → closes #404, half of #393.
+- **Ubu-W** — must pass QE-7/8/9/11 → closes other half of #393.
+- **KDE-W** — must pass QE-7/8/9 + QE-14 + QE-19 → closes #370 (or punts upstream with QE-18 evidence) and confirms the gated patch path still works.
+
+(QE-20 has been folded into QE-19 — the patch ships in every build, so a single bundled-JS check covers both KDE and non-KDE rows.)
+
+Three VMs, ~21 items per row, one full sweep ≈ 90 minutes if the visual checks are batched.
+
+## Per-row pass criteria
+
+| Issue | Closeable when |
+|-------|----------------|
+| #393 | QE-7 through QE-12 pass on **GNOME-W**, **Ubu-W**, and **KDE-W**. QE-19 confirms the patch was applied at build (KDE gate string present). If QE-11 fails on GNOME-W, the KDE-only gate is preserved as a permanent fix; otherwise the patch can be widened. |
+| #404 | QE-2 and QE-3 pass on **GNOME-W**. QE-6 confirms the launcher actually appended `--enable-features=GlobalShortcutsPortal` on GNOME Wayland (S12). |
+| #370 | QE-14 passes on **KDE-W**. **OR** QE-18 records an Electron version > 41.0.4 in the bundled binary and QE-14 still fails — at that point the upstream-regression hypothesis is wrong and we re-investigate. |

+## Sweep mechanics
+
+Per-row procedure (one full pass):
+
+1. Boot VM. Confirm session at greeter matches the row (Wayland vs Xorg, correct DE).
+2. Install the latest build:
+   - DEB: `sudo apt install ./claude-desktop_*.deb`
+   - RPM: `sudo dnf install ./claude-desktop-*.rpm`
+3. Capture environment baseline: `XDG_SESSION_TYPE`, `XDG_CURRENT_DESKTOP`, `gnome-shell --version` or `kwin --version`, `electron --version` (for QE-18).
+4. Launch app. Wait for main window. Run QE-21 input smoke first to catch obvious breakage early.
+5. Run shortcut tests (QE-1 → QE-6) in order. Each run, scrape `~/.cache/claude-desktop-debian/launcher.log` and `pgrep -af claude-desktop` argv.
+6. Run submit tests (QE-7 → QE-13). For each window-state precondition, set the state, then trigger Quick Entry, then submit.
+7. Run visual checks (QE-14 → QE-18). Screenshot QE-14 to attach to #370 if still failing.
+8. Run patch sanity (QE-19 / QE-20).
+9. Update [`matrix.md`](./matrix.md) status cells. Save logs under a row-tagged subdirectory: `~/vms/collected/<row>-<date>/`.
+
+For the deeper #393 bisect (isolating which half of PR #390 regresses GNOME), see the two-variant build instructions in [`~/vms/README.md`](file:///home/aaddrick/vms/README.md) — build a blur-only and a vis-only variant, run QE-7 through QE-11 on each on **Ubu-W** and **GNOME-W**, gate the offending half rather than the whole patch.

+# test-harness runner implementation — session 17 prompt
+
+This file is meant to be **copied verbatim into a fresh Claude Code
+session** as the initial user message. Don't paraphrase it; the
+orchestration depends on the exact directives below.
+
+> **ORCHESTRATION STOPPED AFTER SESSION 16.** This prompt is rotated
+> for completeness only. **Session 17 will NOT run automatically** —
+> the autonomous orchestration was halted at the end of session 16
+> after coverage stalled at 74/76 (97%) for four consecutive sessions
+> (13, 14, 15, 16). To resume, the user must manually trigger another
+> orchestration run AND meet at least one of these preconditions:
+>
+> 1. **Real signed-in Claude Desktop running with `--inspect=9229`**
+>    on the dev box (debugger-attached, signed in, NOT a leaked test
+>    isolation). This unblocks Categories A (operon-mode probe) and
+>    B (Tier 3 read-only reframes that need auth-bearing renderer
+>    state).
+> 2. **A real claude.ai account fixture for write-side state.** The
+>    remaining 2 specs (matrix coverage 74/76 → 76/76) need real
+>    write-side state (e.g. an installed plugin to exercise
+>    `LocalPlugins.listSkillFiles`, or a deep-linked deferred install
+>    intent for T11). The Tier 3 destructive constraint
+>    (`Don't run destructive Tier 3 write-side tests`) explicitly
+>    forbids the harness constructing this state itself.
+> 3. **Renderer-drift event** that requires re-anchoring page-objects
+>    (e.g. claude.ai redesign breaks `findCompactPills`,
+>    `clickMenuItem`, etc.). Triggers a defensive-migration session.
+> 4. **New IPC surface** added by upstream that the harness should
+>    cover (e.g. a new `claude.web` interface, a new eipc method
+>    that's case-doc-anchored).
+>
+> If none of those preconditions hold, the orchestration should NOT

+> marginal output. The structural ceiling of the harness without
+> real-account fixtures is 74/76 (97%); we're already there.
+
+You're picking up after session 16 of the test-harness runner
+implementation work. Session 16 was the final session of the
+sessions-13-to-16 orchestration run and produced: T17 verification
+(session-15 structural fix VERIFIED — bare 60s timeout gone, new
+failure mode at `openFolderPicker` post-`selectLocal` classified as
+renderer-state-dependent and deferred), schema-rev for
+`listRemotePluginsPage` / `listSkillFiles` (both schemas resolved by
+bundle inspection — neither shipped as a Tier 2 invocation because
+`listRemotePluginsPage` is not anchored in any case doc, and
+`listSkillFiles` needs Tier 3 destructive setup). NO coverage gain.
+Plan-doc updated. Followup-prompt rotated with the STOP flag (this
+document).
+
+The plan doc at
+[`docs/testing/runner-implementation-plan.md`](runner-implementation-plan.md)
+captures the tier classification and execution-time reclassifications.
+Its "Status (post-execution)" section is the source of truth for
+what's done and what's deferred — read **session 16** first, then
+**session 15**, **session 14**, **session 13**, **session 12**,
+**session 11**, **session 10**, **session 9**, **session 8**,
+**session 7**, **session 6**, **session 5**, **session 4**, **session
+3**, **session 2**, then **session 1** sub-sections.
+
+This session is a continuation, not a restart. Start by reading the
+plan doc's status sections AND verifying at least one of the
+preconditions above holds. If none hold, STOP and report; don't try
+to fan out.
+
+### Session 16 final findings (key context for any session-17 attempt)
+
+1. **T17's session-15 structural fix VERIFIED.** Bare 60s timeout is
+   gone. `seedFromHost` clones the host's signed-in config,
+   `waitForReady('userLoaded')` resolves to a post-login URL
+   (`https://claude.ai/epitaxy` on the dev box), the dialog mock
+   installs, and `CodeTab.activate({ timeout: 15_000 })` (session 14
+   migration) succeeds first try.
+2. **T17's NEW failure mode is renderer-state-dependent, not AX.**
+   After `selectLocal()` clicks the Local menuitem, the Select-folder
+   pill never appears within 4s. The URL during the run was
+   `/epitaxy` — the user's workspace route. The folder-picker UI
+   may only render on `/new` (or a fresh project), not on a workspace
+   already containing files. To unblock: navigate to `/new`
+   post-userLoaded BEFORE `openFolderPicker()`. NOT shipped session
+   16 — needs a careful navigation primitive that doesn't break
+   existing seedFromHost specs.
+3. **`openPill` / `clickMenuItem` migration STILL parked.** Session
+   16's T17 trace confirmed the env-pill open + Local click both
+   succeeded, ruling out the AX-polling-loop hypothesis once and for
+   all. Don't migrate those speculatively.
+4. **Schema-rev resolved both deferred validators.**
+   `CustomPlugins.listRemotePluginsPage(limit: number, offset:
+   number)`. `LocalPlugins.listSkillFiles(pluginId: string,
+   skillName: string, pluginContext?: opaque)`. Neither shipped as a
+   Tier 2 invocation: `listRemotePluginsPage` is not anchored in any
+   case doc; `listSkillFiles` needs Tier 3 destructive setup.
+5. **Coverage stalled at 74/76 (97%) for 4 consecutive sessions.**
+   Sessions 13-16 net deliverables: 1 primitive, 1 AX migration, 1
+   structural fix, 1 verification + 1 schema-rev investigation.
+   Without real-account fixtures, the harness's structural ceiling
+   is 74/76. The remaining 2 specs need real-account write-side
+   state.
+
+### What a future session 17 might attempt (only if preconditions hold)
+
+If precondition 1 (real signed-in debugger-attached Claude) holds:
+
+- **Operon-mode probe** (Category A from sessions 13-16). Run
+  `eipc-registry-probe.ts` against the user's Claude with operon mode
+  toggled on/off, capture the diff in registered channels. May
+  surface a new case-doc-coverable handler.
+- **Schema-rev smoke-test** for the session-16-resolved schemas
+  against the live debugger. `listRemotePluginsPage(limit: 10,
+  offset: 0)` should return an array shape; `listSkillFiles('some-
+  installed-plugin', 'some-skill')` would test the LocalPlugins
+  handler's auth path.
+
+If precondition 2 (real-account write-side fixture) holds:
+
+- **T11 runtime invocation.** With an installed plugin in
+  `~/.claude/plugins/`, the post-install state can be probed via
+  `listSkillFiles` and the slash-menu skills would assert the
+  case-doc claim "skills appear in the slash menu" (T11 step 3).
+- **T17 navigation fix.** Add a `/new` navigation primitive to
+  `claudeai.ts`'s `CodeTab` so `openFolderPicker` works on a fresh
+  project route. Verify T17 reaches the dialog mock fired assertion.
+
+If precondition 3 or 4 holds:
+
+- **Defensive page-object refactor.** Re-snapshot the AX tree at the
+  Customize panel and Plugin browser modal, refresh case-doc
+  inventory anchors, migrate any decayed selectors.
+
+### Termination signal interpretation
+
+If session 17 is triggered without any precondition met, the right
+move is the same as session 16's STOP recommendation: write a one-
+paragraph "preconditions not met, no work shipped" plan-doc update
+and terminate. Don't burn a session on documentation-only output.
+
+### Constraints to respect (unchanged from sessions 1-16)
+
+- Use `seedFromHost: true` for any auth-required spec — never
+  `CLAUDE_TEST_USE_HOST_CONFIG=1` / `isolation: null` (legacy shape
+  removed in session 15).
+- eipc handlers register on `webContents.ipc._invokeHandlers`, NOT
+  global `ipcMain._invokeHandlers`. Use `lib/eipc.ts`.
+- For arg validator schema-rev: smoke-test first, fall back to
+  bundle-grep on the rejection literal.
+- For AX-tree consumers: use `lib/ax.ts` (`snapshotAx` /
+  `waitForAxNode` / `waitForAxNodes`).
+- For call-site migrations to `waitForAxNode`: keep per-spec retry
+  budgets matching existing tuning.
+- `lib/input.ts` is X11-only. `lib/input-niri.ts` is Niri-only. CDP
+  auth gate is alive (runtime SIGUSR1 attach, never Playwright
+  `_electron.launch()`). BrowserWindow Proxy gotcha — use
+  `webContents.getAllWebContents()`. `skipUnlessRow()` always first.
+- No fixed sleeps. `retryUntil` from `lib/retry.ts`, Playwright
+  auto-wait, or `waitForAxNode` from `lib/ax.ts`.
+- Diagnostics on every run via `testInfo.attach()`. Tag with
+  `severity:` and `surface:` annotations.
+- Tabs in TS, ~80-char wrap.
+- Don't break existing runners. H01-H05 are the canaries.
+- `npm run typecheck` must stay clean.
+- Don't run destructive Tier 3 write-side tests.
+
+### Authoritative reference
+
+Read these in order before fanning out:
+
+- [`docs/testing/runner-implementation-plan.md`](runner-implementation-plan.md)
+  — tier classification + status sections.
+- [`tools/test-harness/README.md`](../../tools/test-harness/README.md)
+  — runner conventions, the 74-spec inventory, primitives in
+  `lib/`, isolation defaults.
+- [`docs/testing/cases/README.md`](cases/README.md) — case-doc
+  structure and the four anchor scopes.
+- [`tools/test-harness/src/lib/`](../../tools/test-harness/src/lib/)
+  — the existing primitives.
+- [`tools/test-harness/src/runners/`](../../tools/test-harness/src/runners/)
+  — every existing spec is a template.
+
+### Phase 0 — calibration (mandatory before fanning out)
+
+1. `cd tools/test-harness && npm run typecheck` — should pass.
+2. Check debugger ATTACHMENT QUALITY (not just port). `ss -tln |
+   grep ':9229'`. If port open, probe webContents via `evalInMain`:
+
+   ```ts
+   import { InspectorClient } from './src/lib/inspector.js';
+   const client = await InspectorClient.connect(9229);
+   const wcs = await client.evalInMain<unknown>(`
+     const { webContents } = process.mainModule.require('electron');
+     return webContents.getAllWebContents().map((w) => ({
+       id: w.id, url: w.getURL(), title: w.getTitle(),
+     }));
+   `);
+   console.log(wcs); client.close();
+   ```
+
+   If every URL is `/login` / `find_in_page` / `main_window`, treat
+   as soft-blocked for auth-required investigations.
+3. Disambiguate running Claude processes. `pgrep -af
+   "ozone-platform=x11.*app.asar"`; for each, inspect cmdline for
+   `user-data-dir`. Real Claude has
+   `~/.config/Claude` (or no user-data-dir flag); leaked test
+   isolations have `/tmp/claude-test-*`.
+4. **Verify at least one precondition for resuming the orchestration
+   holds.** If none hold, write a "no preconditions met" plan-doc
+   update and STOP. Don't fan out.
+
+### Operational notes
+
+- For the bundle-grep schema-rev pattern (sessions 9, 11, 12, 16
+  precedents):
+
+  ```bash
+  cd tools/test-harness && node -e "
+    const {extractFile} = require('@electron/asar');
+    const buf = extractFile(
+      '/usr/lib/claude-desktop/node_modules/electron/dist/resources/app.asar',
+      '.vite/build/index.js'
+    );
+    const s = buf.toString('utf8');
+    const idx = s.indexOf('<rejection-literal>');
+    console.log(s.slice(Math.max(0, idx - 1500), idx + 500));
+  "
+  ```
+
+- For seedFromHost specs: host MUST have a signed-in Claude.
+  `seedFromHost`'s host-claude-kill semantics will tear down any
+  running Claude process — flag clearly in the report before
+  invoking when the user's real Claude is running.
+
+- For AX-tree polling: `lib/ax.ts`'s `waitForAxNode` /
+  `waitForAxNodes` for predicate-based polling.
+
+- The eipc-registry probe (`tools/test-harness/eipc-registry-probe.ts`)
+  is the dedicated tool for inspecting per-wc IPC handler state.
+
+Begin with Phase 0. Don't fan out until at least one of the
+preconditions for resuming the orchestration is verified to hold.

+
+*Generated against [`ui-inventory.json`](./ui-inventory.json) v6 (captured 2026-05-03, app version 1.5354.0, 383 entries).*
+*Reconciled 2026-05-02.*
+
+This file diffs the human-written claims in [`ui/`](./ui/) against the
+machine-captured ground-truth in [`ui-inventory.json`](./ui-inventory.json).
+
+It is one-shot output meant to drive human cleanup of `ui/*.md` — re-run
+the reconciliation script (TODO: not yet built) after major walker passes.
+
+## Reading this document
+
+Three categories of finding per surface:
+
+- **In docs but not in renderer** — the doc names an element that has no
+  corresponding inventory entry. Possible causes (don't read this as "doc
+  is wrong"; the walker covers a subset of reality):
+  - **OS / window-manager element** — title bar, close/min/max buttons,
+    drop shadow, resize edges. These are drawn by the compositor, not by
+    claude.ai's renderer; the walker can't see them.
+  - **Out of renderer scope** — tray menu, libnotify notifications, IME
+    composition popups, Quick Entry popup window. These are main-process
+    or DE-level surfaces that don't exist in the claude.ai DOM.
+  - **Walker coverage gap** — Settings overlay, dialogs, deep Code-tab
+    panes (terminal, file pane, diff). The walker drilled some surfaces
+    but not others; absence here is "not yet observed" not "not present."
+  - **Account-state-dependent** — features that don't appear on this
+    user's plan (e.g. SSH connections panel, managed-settings rows,
+    specific Code-tab pane types).
+  - **Speculative** — doc was written from upstream behavior, not from a
+    Linux build. May not actually render.
+- **In renderer but not in docs** — inventory captured an element that no
+  doc row mentions. Either the doc is incomplete for that surface, or the
+  element is tangential (search-results recency rows, instance-suffix
+  duplicates with `#2`/`+5` markers).
+- **Fingerprint potentially drifted** — doc and inventory agree on the
+  element but the doc's selector hint disagrees with the inventory's
+  `fingerprint.selector`. Most `ui/*.md` rows use prose ("Top-left of
+  topbar") rather than CSS selectors, so this category is small.
+
+Human triage is what closes any of these. Don't auto-edit `ui/*.md`.
+
+## Summary
+
+| Metric | Count |
+|--------|-------|
+| Inventory entries (total) | 383 |
+| Inventory entries by kind | persistent 65 / structural 276 / menu 33 / instance 9 |
+| Inventory entries marked `denylisted: true` | 9 (Send×4, Install×4, Remove×1) |
+| `ui/*.md` files reconciled | 11 (10 surface files + README) |
+| `ui/*.md` rows reconciled (rough — multi-element rows complicate the count) | ~210 element rows across all 10 surface files |
+| Rows with confirmed inventory match | ~70 (~33%) |
+| Rows flagged "in docs but not in renderer" | ~140 (~67%) — heavily skewed by OS-frame, tray, notifications, deep Code panes, Settings, Quick Entry being out-of-renderer or under-walked |
+| Inventory entries with no `ui/*.md` mention | ~190 (~50%) — heavily skewed by per-conversation/per-skill/per-prompt-card structural rows that the docs treat as categories rather than enumerating |
+| Doc rows with explicit selectors that drift from inventory | 0 verified — `ui/*.md` rows almost never carry CSS selectors |
+
+Match counts are approximate. `ui/*.md` rows often describe categories
+("Recent conversations," "Per-history-entry hover") that map to many
+inventory entries; the inventory in turn enumerates structural elements
+the docs intentionally don't list (every project skill button, every
+search result option). The reconciliation is a triage signal, not a
+metric.
+
+## Per-surface breakdown
+
+### `ui/window-chrome-and-tabs.md`
+
+**Inventory surfaces likely covered:** none directly — OS window frame is
+drawn by the compositor; the in-app topbar elements live under `root` as
+`root.button.menu`, `root.button.collapse-sidebar`, `root.button.search`,
+`root.button.back`, `root.button.forward`. The "tab strip" maps to
+`root.button.chat`, `root.button.cowork`, `root.button.code`.
+
+**Doc rows reconciled:** ~22
+
+#### In docs but not in renderer
+
+| Doc element | Reason class |
+|-------------|--------------|
+| Title bar | OS / window-manager |
+| Close button (X) | OS / window-manager |
+| Minimize button | OS / window-manager |
+| Maximize / restore button | OS / window-manager |
+| Resize edges | OS / window-manager |
+| Window menu (right-click titlebar) | OS / window-manager |
+| Cowork ghost icon | Walker captures `root.button.cowork` (the tab) but not the ghost-icon visual within the topbar shim |
+| Drag region (gaps between buttons) | Renders as empty space — not an actionable element |
+| Active tab indicator | Visual styling, not an actionable element |
+| Tab badges (unread / Dispatch) | None observed; user state at capture had no badges |
+| About dialog | Walker did not surface a dialog; About is reachable only from app/tray menu, both out of renderer scope |
+| App menu (macOS-style) | Doc itself notes this is N/A on Linux |
+| Update prompt | Conditional, not present at capture |
+| Crash report dialog | Conditional, not present at capture |
+
+#### In renderer but not in docs
+
+| Inventory entry | Notes |
+|-----------------|-------|
+| `root.button.menu` ("Menu", `aria-label="Menu"`) | This is the doc's "Hamburger menu" — renamed |
+| `root.button.collapse-sidebar` ("Collapse sidebar") | Doc has "Sidebar toggle"; arguably the same |
+| `root.button.search` ("Search") | Doc's "Search icon"; same |
+| `root.button.back` / `root.button.forward` | Doc's back/forward arrows; same |
+| `root.a.skip-to-content` ("Skip to content") | A11y skip link; not in doc |
+| `root.button.new-chat-n` ("New chat⌘N") | Topbar new-chat button; not in doc |
+| `root.button.pinned`, `root.button.recents`, `root.button.projects`, `root.button.artifacts`, `root.button.customize` | Sidebar nav buttons; doc covers some of these in `sidebar.md` not here |
+| `root.button.awaaddrick-max` ("AWAaddrick·Max") | User/plan badge in topbar; not in doc |
+| `root.button.get-apps-and-extensions` | Topbar shortcut to apps page; not in doc |
+| `root.tab.write` / `root.tab.learn` / `root.tab.code` / `root.tab.from-calendar` / `root.tab.from-gmail` | Quick-prompt-template tabs in the prompt area; doc covers Write/Learn/Code as Chat/Cowork/Code tabs but the inventory's `root.tab.code` is distinct from `root.button.code` |
+
+#### Fingerprint potentially drifted
+
+None — doc rows for this surface use Location prose only.
+
+#### Notable cross-cut
+
+The doc's "Chat / Cowork / Code" tab strip maps cleanly to
+`root.button.chat`, `root.button.cowork`, `root.button.code`. But the
+inventory also has `root.tab.code` (a `[role="tab"]`, not a button) which
+is a separate element — the prompt-area template strip — that the doc
+conflates with the main Chat/Cowork/Code switcher. Worth a human note.

+
+### `ui/tray.md`
+
+**Inventory surfaces covered:** none — the tray is a main-process Electron
+`Tray` object on the system SNI bus, not part of claude.ai's DOM.
+
+**Doc rows reconciled:** ~17
+
+#### In docs but not in renderer
+
+Every row, by design. Categories:
+
+- Tray icon (light / dark theme) — main-process `Tray.setImage()`
+- Right-click menu items (Show/Hide, Quick Entry, Open at Login,
+  Settings, About, Quit) — main-process `Menu.buildFromTemplate()`
+- Left-click / double-click / middle-click behaviors — main-process
+  event handlers
+- Tooltip on hover, position, icon resolution, theme switch — SNI
+  daemon and DE behavior
+
+This entire file is correctly out of renderer scope; the walker is doing
+the right thing by not capturing any of it.
+
+#### In renderer but not in docs
+
+N/A — surface mismatch.
+
+---
+
+### `ui/sidebar.md`
+
+**Inventory surfaces likely covered:** `root` (sidebar lives in the root
+chrome on claude.ai). Note: the doc opens "Code Tab Sidebar" but the
+sidebar in the captured renderer is the global claude.ai sidebar, not a
+Code-tab-specific one. The Code-tab-specific session list is captured
+separately under `root.button.code.button.new-session-n` (60 entries).
+
+**Doc rows reconciled:** ~18
+
+#### In docs but not in renderer
+
+| Doc element | Reason class |
+|-------------|--------------|
+| Filter: status / project / environment | Walker did not drill the filter dropdown |
+| Group-by control | Same — within Code-tab session list |
+| Session status indicator (idle/running/...) | Visual decoration on row, not an actionable element |
+| Project / branch label | Same |
+| Diff stats badge `+12 -1` | Conditional — no session at capture had pending diffs |
+| Dispatch badge | Conditional — no Dispatch-spawned session at capture |
+| Scheduled badge | Conditional — same |
+| Hover archive icon | Hover-revealed; walker captures static state |
+| Right-click context menu (Rename / Archive / etc.) | Walker does not synthesise right-clicks |
+| Sidebar resize handle | Visual / draggable, not an aria-labeled element |
+| Sidebar collapse toggle | Inventory has `root.button.collapse-sidebar` but doc treats it as a Code-tab element rather than chrome |
+| Scrollbar | OS / theme-rendered |
+| `Ctrl+Tab` / `Ctrl+Shift+Tab` cycling | Keyboard shortcut, not a UI element |
+
+#### In renderer but not in docs
+
+| Inventory entry | Notes |
+|-----------------|-------|
+| `root.button.fine-tuning-diffusion-models-with-reinforcement-learning` | A pinned recent conversation — sidebar content |
+| `root.button.more-options-for-fine-tuning-diffusion-models-with-reinforce` | Per-row menu trigger — doc mentions "right-click context menu" but inventory shows it's a discoverable button |
+| `root.button.how-to-use-claude` + `root.button.more-options-for-how-to-use-claude` | Same pattern |
+| `root.button.code.button.routines` | "Routines" link in Code-tab nav — doc's "Routines link" is here |
+| `root.button.code.button.more-navigation-items` | Likely the doc's "Customize / Routines" expander — not enumerated |
+| `root.button.code.button.filter` | The doc's "Filter: status" probably maps here |
+| `root.button.code.button.appearance` | Not in doc |
+| `root.button.code.button.show-5-more` | Pagination; not in doc |
+| `root.button.code.button.open-session-*` (5 entries) | Each is a single session row in the Code-tab list — the doc's "Per-session row" category |
+
+#### Fingerprint potentially drifted
+
+None — doc rows for this surface use Location prose only.
+
+---
+
+### `ui/prompt-area.md`
+
+**Inventory surfaces likely covered:** `root` (top-level prompt area
+buttons), `root.button.add-files-connectors-and-more` (the `+` menu),
+`root.button.model-opus-4-7-adaptive` (model picker), and several deep
+sub-surfaces.
+
+**Doc rows reconciled:** ~28
+
+#### In docs but not in renderer
+
+| Doc element | Reason class |
+|-------------|--------------|
+| Input field | The contenteditable / textarea itself isn't captured (no aria-label) |
+| Placeholder text | Not an interactive element |
+| Cursor caret / multi-line autosize / word wrap | Behavior, not element |
+| Paste plain text / paste image | Behavior |
+| `Enter` to send / `Shift+Enter` / `Esc` | Keyboard behavior |
+| IME composition | Not a renderer element |
+| Attachment button (left of input) | Not surfaced — possibly bundled into `root.button.add-files-connectors-and-more` |
+| File-attached chip | Conditional — no attachment at capture |
+| Multiple attachments / image preview / PDF preview | Conditional |
+| Drag-drop overlay | Conditional, only renders during drag |
+| `@filename` autocomplete | Conditional, only renders when typing `@` |
+| `+` button | Likely IS the `root.button.add-files-connectors-and-more` button — see below |
+| Slash menu (all rows: Built-in / Project skills / User skills / Plugin skills / filter / selection / `Esc`) | Walker did not type `/` to trigger the slash menu; no inventory entries |
+| Effort picker (`Cmd+Shift+E`) | Possibly inside `root.button.code.button.opus-4-7-1m-extra-high` — uncertain |
+| Stop button (replaces Send while responding) | Conditional — no in-flight response at capture |
+| Usage ring | Possibly `root.button.code.button.usage-plan-11` ("Usage: plan 11%") |
+
+#### In renderer but not in docs
+
+| Inventory entry | Notes |
+|-----------------|-------|
+| `root.button.press-and-hold-to-record` ("Press and hold to record") | Voice / dictation button in prompt area — doc has no voice input row |
+| `root.button.code.button.dictation-settings` | Dictation settings button |
+| `root.button.code.button.transcript-view-mode` | Transcript view toggle in prompt area |
+| `root.button.code.button.scroll-to-bottom` | Scroll-to-bottom affordance |
+| `root.button.code.button.accept-edits` | Permission-mode-related quick action |
+| `root.button.code.button.add` ("Add") | Likely the doc's `+` button, with a different label |
+| `root.button.code.button.usage-plan-11` ("Usage: plan 11%") | Probably the doc's "Usage ring" |
+| `root.button.code.button.opus-4-7-1m-extra-high` ("Opus 4.7 1M· Extra high") | Probably the doc's "Effort picker" |
+| All `root.button.add-files-connectors-and-more.menuitem.*` entries (Add files or photos / Add to project / Skills / Connectors / Plugins / Research / Web search / Use style) | The `+` menu contents — doc has Slash commands / Skills / Connectors / Plugins / Add plugin; inventory surfaces additional items the doc misses (Add files or photos, Add to project, Web search, Use style) |
+| `root.button.add-files-connectors-and-more.menuitem.use-style.*` (8 entries: Normal / Learning / Concise / Explanatory / Formal / Create & edit styles / Research mode) | Style picker is a whole sub-surface the doc doesn't mention |
+| `root.button.model-opus-4-7-adaptive.menuitemradio.*` (Opus / Sonnet / Haiku / Adaptive thinking / More models) | Doc says "Sonnet, Opus, Haiku" — inventory adds Adaptive thinking + More models |
+
+#### Fingerprint potentially drifted
+
+| Doc claim | Inventory says |
+|-----------|----------------|
+| `+` button → opens menu of "Slash commands / Skills / Connectors / Plugins / Add plugin" | The corresponding inventory button is labeled "Add files, connectors, and more" with `aria-label="Add files, connectors, and more"`. Menu contents don't include "Slash commands" or "Add plugin" sub-entry — doc menu structure is partly speculative |
+

+
+### `ui/code-tab-panes.md`
+
+**Inventory surfaces likely covered:** `root.button.code` (23 entries),
+`root.button.code.button.new-session-n` (60 entries) — but no per-pane
+sub-surfaces (no diff pane, no terminal pane, no preview pane, no file
+pane).
+
+**Doc rows reconciled:** ~50
+
+#### In docs but not in renderer
+
+Almost every Code-tab pane row is missing from the inventory. The walker
+landed in the Code-tab "New session" shell but did not open or drill any
+of the panes. Categories:
+
+| Pane | Doc rows missing | Reason |
+|------|------------------|--------|
+| Pane chrome (header, drag/resize handles, close button, Views menu) | 5 rows | Walker coverage gap — no pane was open |
+| Diff pane | 9 rows (file list, diff content, line click, Cmd+Enter, Accept/Reject, Review code) | Walker coverage gap |
+| Preview pane | 11 rows | Walker coverage gap |
+| Terminal pane | 7 rows | Walker coverage gap (also: only renders for Local sessions) |
+| File pane | 7 rows | Walker coverage gap |
+| Tasks / subagent pane | 5 rows | Walker coverage gap |
+| Side chat overlay | 3 rows (trigger / content / close) | `root.button.code.button.close-side-chat` IS captured — the close button — but content isn't drilled |
+| CI status bar | 5 rows | Conditional — no PR open at capture |
+| View modes (Normal/Verbose/Summary) | 3 rows | Possibly behind `root.button.code.button.transcript-view-mode` — single inventory entry vs. 3 doc rows |
+
+#### In renderer but not in docs
+
+| Inventory entry | Notes |
+|-----------------|-------|
+| `root.button.code.button.local` ("Local") | Environment switcher chip — not in doc |
+| `root.button.code.button.select-folder` ("Select folder…") | Folder-picker entry — doc references this only via T17 cross-reference |
+| `root.button.code.button.send` (and `#2`, both denylisted) | Send button — doc has it under prompt-area, not panes |
+| `root.button.code.button.transcript-view-mode` | The doc's "Transcript view dropdown" — single inventory entry |
+| `root.button.code.button.opus-4-7-1m-extra-high` | Model selector inside Code-tab session shell |
+| `root.button.code.button.usage-plan-11` | Usage ring inside Code-tab session shell |
+| `root.button.code.button.accept-edits` ("Accept edits") | Permission-mode quick action — not in doc |
+| All 60 `root.button.code.button.new-session-n.button.open-session-*` and per-session entries | Doc covers the session list in `sidebar.md`, not here, so this isn't really a gap for `code-tab-panes.md` |
+
+#### Fingerprint potentially drifted
+
+None — doc is prose-only.
+
+---
+
+### `ui/settings.md`
+
+**Inventory surfaces likely covered:** `root.button.settings` (only 1
+entry — "Settings" button itself), `root.button.awaaddrick-max.menuitem.settingsctrl`
+(the menu-item route to Settings, label "SettingsCtrl,").
+
+**Doc rows reconciled:** ~28
+
+#### In docs but not in renderer
+
+The Settings page itself is essentially un-walked. Settings opens as an
+overlay/modal which the walker treated as a single button rather than
+drilling into. Every row in the doc beyond "Settings window opens" lacks
+a matching inventory entry:
+
+| Doc section | Rows missing | Reason |
+|-------------|--------------|--------|
+| Settings root (close button, sidebar nav) | 3 rows | Walker coverage gap |
+| Desktop app → General (Computer use, Keep computer awake, Denied apps, Unhide apps, Theme picker) | 5 rows | Walker coverage gap; some rows account-state-dependent |
+| Desktop app → Account (name/email, plan badge, Sign out) | 3 rows | Walker coverage gap |
+| Claude Code (Worktree location, Branch prefix, Auto-archive toggle, Persist preview, Preview toggle, Bypass-permissions toggle, Auto mode availability) | 7 rows | Walker coverage gap |
+| Connectors page (list, per-connector entry, Manage, Disconnect, Add connector) | 5 rows | Walker coverage gap; partially covered by the in-session connectors menu |
+| SSH connections (list, Add SSH connection button, per-connection entry) | 3 rows | Walker coverage gap; account-state-dependent |
+| Keyboard shortcuts (list, value, Reset, Quick Entry shortcut) | 4 rows | Walker coverage gap |
+| Local environment editor (open, Add variable, Remove variable, Apply to dev servers) | 4 rows | Walker coverage gap; account-state-dependent |
+
+#### In renderer but not in docs
+
+| Inventory entry | Notes |
+|-----------------|-------|
+| `root.button.settings` ("Settings", `aria-label="Settings"`) | The button that opens Settings — confirmed in chrome |
+| `root.button.awaaddrick-max.menuitem.settingsctrl` ("SettingsCtrl,") | Settings menu item under the user/plan menu — alternate path |
+
+#### Fingerprint potentially drifted
+
+None.
+
+#### Walker coverage note
+
+Settings is a known walker coverage gap (see preamble). This doc is
+substantively un-reconciled until a Settings drill pass lands.
+
+---
+
+### `ui/routines-page.md`
+
+**Inventory surfaces likely covered:** none directly. Routines are
+reachable via `root.button.code.button.routines`, but the page itself
+isn't drilled.
+
+**Doc rows reconciled:** ~26
+
+#### In docs but not in renderer
+
+Every doc row except the "Routines page link" itself is unmatched — the
+walker captured the entry point but did not open the Routines page.
+
+| Doc section | Rows missing | Reason |
+|-------------|--------------|--------|
+| Routines list (header, New routine button, list, per-routine row, Run-now icon, Pause/resume, click row) | 7 rows | Walker coverage gap |
+| New routine form Local (Name, Description, Instructions, permission-mode picker, model picker, Working folder, Worktree toggle, Schedule preset, Time picker, Day picker, Save, Cancel, Folder-trust prompt) | 13 rows | Walker coverage gap |
+| New routine form Remote (Trigger type, Connectors picker, Network access controls) | 3 rows | Walker coverage gap; doc itself is partly speculative ("Per upstream docs") |
+| Routine detail (Run now, Active/Paused toggle, Edit, Delete, Review history, hover tooltip, Show more, Always allowed, Revoke approval) | 9 rows | Walker coverage gap |
+
+#### In renderer but not in docs
+
+| Inventory entry | Notes |
+|-----------------|-------|
+| `root.button.code.button.routines` ("Routines") | The entry-point link — doc's "Routines page link" |
+
+#### Fingerprint potentially drifted
+
+None.
+

+
+### `ui/connectors-and-plugins.md`
+
+**Inventory surfaces likely covered:** `root.button.add-files-connectors-and-more.menuitem.connectors`
+(the in-session connector picker, 5 entries), plus the deeper per-connector
+sub-surfaces under `.connectors.menuitemcheckbox.gmail.*` (15 entries).
+Plugin browser surfaces (`root.button.back.*`) cover Skills, Connectors,
+Add plugin, Typescript lsp, Php lsp, Playwright, Connectors, etc.
+
+**Doc rows reconciled:** ~24
+
+#### In docs but not in renderer
+
+| Doc element | Reason class |
+|-------------|--------------|
+| Connectors menu — "Per-connector row" with status indicator | Inventory has Gmail and Google Calendar but not status decorations |
+| Empty state | Conditional — user has connectors configured |
+| Connector catalog (modal body, per-connector tile with logo/description) | Walker coverage gap — the Add-connector flow opens a modal that wasn't drilled |
+| OAuth in-app overlay | Conditional, not present at capture |
+| Permission consent screen | External (provider's UI) |
+| Callback completion | Behavior, not an element |
+| Custom connector entry point | Walker coverage gap |
+| Plugin browser modal (browser modal, marketplace selector, per-plugin tile, scope selector, install progress, success state, error state) | Walker captured plugin surfaces under `root.button.back.*` (Add plugin, Typescript lsp, Php lsp, Playwright) but not the modal anatomy |
+| Manage plugins (installed list, per-plugin row, Enable toggle, Plugin skills sub-list) | Walker coverage gap — no Manage-plugins surface drilled |
+
+#### In renderer but not in docs
+
+| Inventory entry | Notes |
+|-----------------|-------|
+| `root.button.add-files-connectors-and-more.menuitem.connectors` ("Connectors", in-session menu) | Doc covers this — the in-session Connectors menu |
+| `root.button.add-files-connectors-and-more.menuitem.connectors.menuitemcheckbox.gmail` ("Gmail") | Per-connector row — doc "Per-connector row" category |
+| `root.button.add-files-connectors-and-more.menuitem.connectors.menuitemcheckbox.google-calendar` ("Google Calendar") | Per-connector row — same |
+| `root.button.add-files-connectors-and-more.menuitem.connectors.menuitem.manage-connectors` ("Manage connectors") | Doc's "Manage connectors entry" |
+| `root.button.add-files-connectors-and-more.menuitem.connectors.menuitem.add-connector` ("Add connector") | Doc has "Add connector button" in Settings; inventory shows it also exists in the in-session menu |
+| `root.button.add-files-connectors-and-more.menuitem.connectors.menuitem.tool-accessload-tools-when-needed` ("Tool accessLoad tools when needed") | Per-connector tool-access setting — not in doc |
+| `root.button.back.a.skills` ("Skills") | Plugin browser — Skills tab |
+| `root.button.back.a.connectors` / `root.button.back.a.connectors#2` (both "Connectors") | Plugin browser — Connectors tab (instance suffix `#2` indicates duplicate detection) |
+| `root.button.back.button.add-plugin` ("Add plugin") | Plugin browser — Add plugin button |
+| `root.button.back.a.typescript-lsp` / `root.button.back.a.php-lsp` / `root.button.back.a.playwright` | Installed plugins — doc treats this as "Manage plugins → Per-plugin row," walker captures the actual plugin names |
+| `root.button.back.button.connect-your-appslet-claude-read-and-write-to-the-tools-you-` ("Connect your appsLet Claude read...") | Plugin browser landing pane CTA — not in doc |
+| `root.button.back.a.create-new-skillsteach-claude-your-processes-team-norms-and-` ("Create new skillsTeach Claude your processes, team norms, and expertise.") | Skills-creation CTA — not in doc |

+| `root.button.add-files-connectors-and-more.menuitem.connectors.menuitemcheckbox.gmail.button.develop-storytelling-frameworks` and 9 similar `.option`/`.button` pairs | Connector-suggested prompt cards. Walker captured these as a side-effect of drilling Gmail — they aren't a doc-targeted UI element |
+
+#### Fingerprint potentially drifted
+
+| Doc claim | Inventory says |
+|-----------|----------------|
+| `+` → **Connectors** opens "Connectors menu" | Inventory: button is "Add files, connectors, and more" not "+"; menu item is "Connectors". Functionally the same surface |
+

+
+### `ui/quick-entry.md`
+
+**Inventory surfaces covered:** none — Quick Entry is a separate
+`BrowserWindow` constructed in the main process (`index.js:515375`), not
+part of claude.ai's renderer. The walker started at `https://claude.ai/new`
+which never reaches it.
+
+**Doc rows reconciled:** ~17
+
+#### In docs but not in renderer
+
+Every row, by design. Categories:
+
+- Window appearance (frame, background, rounded corners, drop shadow,
+  position, always-on-top, lifecycle, persistence after main destroy) —
+  main-process BrowserWindow construction
+- Input area (text input, placeholder, multi-line, Enter/Shift+Enter,
+  Esc, click-outside, paste, IME) — popup renderer (separate from
+  claude.ai)
+- Submit feedback (transition, loading, error) — popup renderer + IPC
+  bridge
+
+This entire file is correctly out of renderer scope. Doc rows are
+already heavily annotated with `index.js:515xxx` references to upstream
+main-process source — that's the right substrate.
+
+#### In renderer but not in docs
+
+N/A — surface mismatch.
+
+---
+
+### `ui/notifications.md`
+
+**Inventory surfaces covered:** none — notifications fire via libnotify
+on the `org.freedesktop.Notifications` DBus path; they are not DOM
+elements.
+
+**Doc rows reconciled:** ~17
+
+#### In docs but not in renderer
+
+Every row, by design. Categories:
+
+- Notification sources (Scheduled fires, Catch-up, CI status, PR merged,

+- Per-notification anatomy (App identity, icon, title, body, actions,
+  click target) — DBus payload
+- Per-DE rendering (KDE/GNOME/Mako/Dunst/swaync/Niri) — daemon behavior

+## Top-level findings
+
+### Coverage by source-of-truth axis
+
+- **OS-level / window-manager elements** (window-chrome rows for
+  title bar, close/min/max, resize edges, drop shadow) — never going to
+  appear in the renderer inventory. ~10 doc rows.
+- **Main-process Electron windows** (Quick Entry popup, About dialog,
+  crash dialog, file pickers) — never going to appear in the renderer
+  inventory. ~25 doc rows.
+- **Tray menu** (Show/Hide, Quick Entry, Settings, About, Quit, Open
+  at Login) — main-process `Menu.buildFromTemplate()`. ~12 doc rows.
+- **libnotify notifications** — DBus, not DOM. ~17 doc rows.
+- **Walker coverage gaps** (Settings overlay, Routines page, plugin
+  browser modal, all Code-tab panes, dialogs, slash menu, drag-drop
+  overlay) — would appear if the walker drilled them. ~70 doc rows.
+- **Account-state-dependent surfaces** (CI bar, Dispatch badges, file
+  attachments, SSH connections panel) — would appear in some sessions
+  but didn't at capture. ~15 doc rows.
+- **Conditional / hover / behavior** (right-click context menus, hover
+  archive icons, drag-drop overlays, tooltips) — wouldn't appear in a
+  static walker pass even if the surface was visited. ~10 doc rows.
+
+The combined explanation: roughly half of the "in docs but not in
+renderer" mismatches are unfixable (different source of truth), and
+roughly half are walker coverage gaps that future passes can close.
+
+### Top 3 surfaces with the most "in docs but not in renderer" mismatches
+
+These are likely candidates for speculative claims OR for un-walked
+surfaces. Treat as triage queue:
+
+1. **`ui/code-tab-panes.md`** — ~50 unmatched rows. Almost entirely
+   walker-coverage gap (the walker landed in the Code-tab shell but
+   opened no panes). Until the walker drills diff/preview/terminal/file/
+   tasks panes, this doc is un-reconcilable.
+2. **`ui/settings.md`** — ~28 unmatched rows. Settings opens as an
+   overlay; walker captured only the Settings entry-point button. Needs
+   targeted drill.
+3. **`ui/routines-page.md`** — ~26 unmatched rows. Same shape as
+   Settings — entry-point captured, page contents unwalked.
+
+### Top 3 surfaces with the most "in renderer but not in docs" surplus
+
+These docs are most-incomplete relative to ground truth:
+
+1. **`ui/sidebar.md`** — Inventory has 60+ Code-tab session-list entries
+   under `root.button.code.button.new-session-n`. Doc treats sessions as
+   a single category row. This is intentional doc behavior, but it means
+   the doc doesn't help when reasoning about the actual structural
+   buttons (Filter, Appearance, Routines, More navigation items, Show 5
+   more, etc.) that the walker found.
+2. **`ui/prompt-area.md`** — Inventory has the entire Use-style picker
+   sub-tree (Normal / Learning / Concise / Explanatory / Formal / Create
+   & edit styles + 5 preset cards), the Press-and-hold-to-record voice
+   button, dictation settings, transcript view mode, scroll-to-bottom,
+   and the model picker's "Adaptive thinking" / "More models" entries —
+   none of which the doc enumerates.
+3. **`ui/connectors-and-plugins.md`** — Inventory has the entire plugin
+   browser sub-tree (`root.button.back.*` — 12 entries: Skills, Add
+   plugin, Typescript lsp, Php lsp, Playwright, Browse plugins, Create
+   new skills, Connect your apps, Connectors×2, Back to Claude, Select
+   a folder), and connector-suggested prompt cards (10 entries under
+   `.gmail.button.*`). Doc treats these surfaces at a higher level of
+   abstraction.
+
+## Acknowledged gaps in inventory itself
+
+Not all inventory absences are doc errors. Known walker gaps as of v6:
+
+- **Settings page deep content** — only the entry-point button
+  (`root.button.settings`) and the menu shortcut
+  (`...menuitem.settingsctrl`) captured. Settings opens as an overlay
+  the walker did not drill.
+- **Dialogs** — 0 captured. claude.ai may not use `[role=dialog]` for
+  most modals, or the walker's drill paths didn't reach them.
+- **Code tab panes** — only the Code-tab session shell was drilled;
+  diff, preview, terminal, file, tasks, subagent, plan, side chat, CI
+  bar are uncaptured.
+- **Routines page** — only the entry-point link was captured.
+- **Plugin browser modal anatomy** — surrounding list captured, the
+  per-plugin install modal wasn't.
+- **Slash menu** — walker did not type `/` to trigger.
+- **Hover/right-click/drag-only affordances** — static walker; no
+  context menus or drag-drop overlays.
+- **Quick Entry / Tray / Notifications** — out of renderer scope.
+
+These are walker tickets, not bugs against the v6 capture.
+
+## Triage suggestions for `ui/*.md` cleanup
+
+Aimed at humans editing the docs. Ordered by impact:
+
+1. **Mark out-of-renderer surfaces explicitly.** `ui/tray.md`,
+   `ui/quick-entry.md`, `ui/notifications.md`, and the OS-frame section
+   of `ui/window-chrome-and-tabs.md` already reference main-process
+   source and DE behavior — add a header note that this surface
+   intentionally doesn't appear in `ui-inventory.json`.
+2. **Annotate walker-coverage-gap surfaces.** `ui/code-tab-panes.md`,
+   `ui/settings.md`, `ui/routines-page.md` — header note that the
+   inventory does not yet drill these surfaces; rows reflect upstream
+   behavior and are unverified in the renderer.
+3. **Add missing topbar/prompt-area elements** to `ui/window-chrome-and-tabs.md`
+   and `ui/prompt-area.md` from the "In renderer but not in docs" lists.
+4. **Decide the doc/inventory boundary for sidebar session lists.** Doc
+   treats sessions as a category; inventory enumerates each. Pick one
+   shape and document it.
+5. **Flag speculative Linux-conditional rows** — `ui/settings.md` SSH
+   connections, "Denied apps" / "Unhide apps when Claude finishes" for
+   Computer Use — mark as "may not render on Linux; verify before
+   assuming."

+# UI snapshots
+
+Captured renderer state for the `claude.ai` web view, taken via the
+`explore` CLI in [`tools/test-harness/explore/`](../../../tools/test-harness/explore/).
+Use these to detect upstream UI drift before it breaks the harness.
+
+The snapshot JSON files themselves are gitignored
+(`docs/testing/ui-snapshots/*.json`) — they're noisy diffs and
+specific to the moment of capture. This directory is checked in so the
+path exists; the README + `.gitkeep` are the only tracked files.
+
+## Capture
+
+Requires a running `claude-desktop` build with the main-process
+debugger attached on port 9229 (Developer menu → Enable Main Process
+Debugger). Then, from `tools/test-harness/`:
+
+```sh
+npx tsx explore/explore.ts snapshot baseline-code-tab
+# → wrote /…/docs/testing/ui-snapshots/baseline-code-tab.json
+```
+
+Snapshot names are restricted to `[a-zA-Z0-9._-]`.
+
+## Compare
+
+```sh
+npx tsx explore/explore.ts diff baseline-code-tab after-feature-x
+```
+
+Add `--json` for machine-readable output. Add `--exit-on-diff` to fail
+the process (exit code 3) when there are any entries — useful inside a
+CI guard.
+
+`diff` arguments accept either a bare name (looked up in this dir,
+`.json` appended) or an explicit path.
+
+### What counts as a diff
+
+| Kind      | Meaning                                                 |
+|-----------|---------------------------------------------------------|
+| `removed` | Element keyed in A absent from B (drift signal).        |
+| `changed` | Same key, different visible text or structural detail.  |
+| `added`   | New key in B (informational only — surface gained).     |
+
+## Snapshot shape
+
+```jsonc
+{
+  "capturedAt": "2026-05-02T17:30:00Z",
+  "claudeAiUrl": "https://claude.ai/…",
+  "appVersion": "1.1.7714",        // from app.getVersion(), null on failure
+  "pageState":         { "url", "title", "readyState" },
+  "dfPills":           [ /* Chat / Cowork / Code top-level tabs */ ],
+  "compactPills":      [ /* env pill, Select-folder pill, … */ ],
+  "ariaLabeledButtons":[ /* every <button[aria-label]>, capped at 200 */ ],
+  "openMenu":          { "ariaLabelledBy", "ariaLabel", "items": [...] },
+  "modals":            [ /* role=dialog with heading + buttons */ ]
+}
+```
+
+Discovery is by **structural shape**, never by minified Tailwind class
+names. See the why-block at the top of
+[`tools/test-harness/explore/snapshot.ts`](../../../tools/test-harness/explore/snapshot.ts)
+for the rationale.
+
+## Other subcommands
+
+```sh
+npx tsx explore/explore.ts            # full snapshot to stdout
+npx tsx explore/explore.ts pills      # df-pills + compact-pills + state
+npx tsx explore/explore.ts menu       # currently-open menu (or null)
+npx tsx explore/explore.ts find <re>  # regex search over text + aria-label
+```
+
+`find` regex is case-insensitive by default.

+# UI Element Inventory
+
+This directory holds per-surface UI checklists. Where [`../cases/`](../cases/) tests verify *behavior end-to-end*, files here verify *every UI element renders and responds* on Linux.
+
+## Why a separate directory
+
+A functional test like [T17 — Folder picker opens](../cases/code-tab-foundations.md#t17--folder-picker-opens) verifies the folder picker works. A UI checklist asks the smaller, more granular questions:
+
+- Is the **Select folder** button visually present?
+- Does its hover state render?
+- Is the icon next to it the correct shape on a HiDPI screen?
+- Does it tab-focus correctly?
+- Does it have an accessible name (a11y)?
+
+Functional tests catch "the feature broke." UI checklists catch "the feature works but looks wrong." Both matter on Linux because Electron under different DEs / display servers / GTK theme combinations produces visual artifacts that aren't behavioral failures.

+## Standard checklist row
+
+Each UI file uses tables of the form:
+
+| Element | Selector / location | Expected | Notes |
+|---------|---------------------|----------|-------|
+| Close button | Top-right of titlebar | Renders, hover state visible, click hides to tray (see T08) | KDE-W: ✓ |
+
+Columns:
+
+- **Element** — human-readable name.
+- **Selector / location** — DOM selector if known, otherwise plain-language pointer ("right-click menu, second item from top"). The selector column is what becomes a Playwright/CDP assertion when automation lands.
+- **Expected** — what the user should see / what should happen on click. Concise.
+- **Notes** — known issues, environment caveats, screenshot links.
+
+## Sweep workflow
+
+A UI sweep on a row:
+
+1. Take a baseline screenshot of each surface (`scrot`, `gnome-screenshot`, `grim`, `flameshot`).
+2. Walk each table top-to-bottom. For each row, look at the element, click/hover/tab to it, compare against Expected.
+3. Mark anomalies in the **Notes** column or file an issue if the deviation is environment-specific.
+4. Save screenshots of any failure to a dated folder; reference them inline.
+
+UI rows don't have stable IDs (`T##` / `S##`) — they're append-only checkpoints. When something becomes a regression candidate worth tracking long-term, promote it to a functional test in [`../cases/`](../cases/).
+
+## Automation roadmap
+
+Each UI checklist row is a candidate Playwright (via [Electron driver](https://playwright.dev/docs/api/class-electron)) or `xdotool` assertion:
+
+```typescript
+// Playwright shape
+await page.locator('[data-testid="close-button"]').click()
+await expect(window).toBeHidden()
+```
+
+Or for pure visual diffing:
+
+```bash
+# scrot + perceptualdiff
+scrot -u baseline.png
+# ... interaction ...
+scrot -u current.png
+perceptualdiff baseline.png current.png
+```
+
+The structure here is intentionally diff-friendly: rows are stable, tables are append-only, selectors live in their own column.

+# UI — Desktop Notifications
+
+Notification rendering across DEs. The app dispatches notifications via `org.freedesktop.Notifications` (libnotify spec); each DE renders them differently.

+
+## Notification sources
+
+The app posts notifications for the following events. Each should fire reliably on every supported DE.
+
+| Source | Trigger | Expected text | Click action | Notes |
+|--------|---------|---------------|--------------|-------|
+| Scheduled task fires | When a routine starts a run | "Scheduled task `<name>` started" or similar | Focus the new session in sidebar | Crosses with [T27](../cases/routines.md#t27--scheduled-task-fires-and-notifies) |

+| PR merged (auto-archive trigger) | When watched PR merges | "PR `<title>` merged. Session archived" | — | Crosses with [T30](../cases/code-tab-workflow.md#t30--auto-archive-on-pr-merge) |
+| Dispatch handoff | When a Dispatch task creates a Code session | "Dispatch session ready: `<task>`" | Focus the new Dispatch-badged session | Crosses with [S24](../cases/platform-integration.md#s24--dispatch-spawned-code-session-appears-with-badge-and-notification) |
+| Permission prompt awaiting approval | When a session in Ask mode needs user approval | "Claude needs your approval" | Focus the awaiting session | Sessions in Ask mode stall until answered |

+## Per-notification anatomy

+|---------|----------|-------|
+| App identity | "Claude" or "Claude Desktop" as the source | DE-specific (Plasma shows the app name and icon prominently) |
+| Notification icon | App icon (theme-aware) | Should match the same icon set as the tray |
+| Title | Short event headline | One line, no truncation issues for typical lengths |
+| Body | One or two short lines of context | Wrap correctly for the DE's notification width |
+| Actions (if any) | Inline buttons (e.g. "Open", "Dismiss") | Some DEs show actions, some require expand |
+| Click target | Activates the relevant session/window | — |
+
+## Per-DE rendering
+
+| DE / daemon | Expected render | Caveats |
+|-------------|-----------------|---------|
+| KDE Plasma | KDE notification daemon (KNotifications); appears top-right by default; inline action buttons supported | — |
+| GNOME Shell | gnome-shell built-in; appears top-center; limited action support | — |
+| Mako (wlroots) | Stacked notifications top-right by default; supports actions if config allows | — |
+| Dunst | Lightweight; respects `~/.config/dunst/dunstrc`; actions via keybinds | — |
+| swaync (Sway) | Notification center + popups | — |
+| Niri | Compositor-provided; usually a portable daemon (mako, dunst) | — |
+
+## Notification persistence
+
+| Element | Expected | Notes |
+|---------|----------|-------|
+| Notification history | DE-dependent (KDE has notification panel; GNOME has Calendar drawer; mako/dunst can be configured) | Don't rely on persistence — assume fire-and-forget |
+| Do-not-disturb mode | Respect DE's DND state | If user has DND on, notifications shouldn't fire — verify the daemon honors this |
+
+## Failure modes to watch for
+
+| Symptom | Likely cause | Diagnose with |

+| No notifications appear | No daemon running; service not registered | `gdbus call --session --dest=org.freedesktop.Notifications --object-path=/org/freedesktop/Notifications --method=org.freedesktop.DBus.Introspectable.Introspect`; `notify-send "test"` from terminal |
+| Notification fires but no icon | Icon path resolution failed; theme strip | Inspect the dbus call body for `app_icon` value |
+| Click does nothing | Action handler IPC missed; window already focused | Click while main window is hidden — does it appear? |
+| Title/body cut off | DE truncation policy | Test with shorter strings to confirm content vs. layout |
+| Notifications fire even in DND | Daemon ignoring DND, or our app sets `urgency=critical` inappropriately | Check `urgency` hint in the dbus call |
+| Notification persists indefinitely | `expire_timeout=-1` (never) used inappropriately | Confirm timeout passed in the dbus call |
+| Per-source duplicates | Multiple subscribers to the same event | Diagnose by isolating one source at a time |

+
+## Window appearance
+
+| Element | Location | Expected | Notes |
+|---------|----------|----------|-------|
+| Window frame | None (frameless popup) | No OS-titlebar; no close/min/max buttons | Upstream sets `frame: false` on the BrowserWindow (`index.js:515381`) |
+| Background | Behind prompt UI | Transparent (no opaque square frame visible) on KDE Plasma Wayland ([S10](../cases/shortcuts-and-input.md#s10--quick-entry-popup-is-transparent-no-opaque-square-frame)) | Upstream already sets both `transparent: true` and `backgroundColor: "#00000000"` (`index.js:515380, 515383`). #370 regression is below the option-passing layer (Electron 41.0.4 CSD rework). KDE-W: pending; bug if opaque |
+| Rounded corners | Outer edge of UI | Visible | Compositor must support corner rounding via shaders / clip mask |
+| Drop shadow | Around popup | macOS-only at the Electron level; on Linux/Windows depends entirely on compositor | Upstream sets `hasShadow: Zr` where `Zr === process.platform === "darwin"` (`index.js:515384`). Linux is expected to render via compositor shadow support; wlroots without server-side decorations will not show one |
+| Position | Last-saved position, keyed on monitor; falls back to primary display if monitor is gone | Popup remembers its position across invocations and across app restarts ([S35](../cases/shortcuts-and-input.md#s35--quick-entry-popup-position-is-persisted-across-invocations-and-across-app-restarts), [S36](../cases/shortcuts-and-input.md#s36--quick-entry-popup-falls-back-to-primary-display-when-saved-monitor-is-gone)) | Upstream uses `an.get("quickWindowPosition")` (`index.js:515491-515526`) keyed on monitor label + resolution. Falls back to `cHn()` (`:515502`) when the saved monitor is gone. **Upstream does NOT place on cursor display or focused-window display** — it's last-position or primary, nothing else |
+| Always-on-top | Window manager hint | Stays above other windows | Upstream sets `alwaysOnTop: true` with level `"pop-up-menu"` (`index.js:515399`). On macOS this is per-app; on Linux compositors the level hint is interpreted variably |
+| Lifecycle | Lazy-created on first shortcut press | First shortcut press constructs the BrowserWindow; subsequent presses reuse it ([S29](../cases/shortcuts-and-input.md#s29--quick-entry-popup-is-created-lazily-on-first-shortcut-press-closed-to-tray-sanity)) | Upstream `if (!Ko \|\| ...) Ko = new BrowserWindow(...)` near `index.js:515375`. Means popup works in tray-only state with no main window mapped |
+| Persistence after main window destroy | Popup survives `mainWindow.destroy()` | Popup remains functional; submit guards skip show/focus when `ut` is destroyed ([S37](../cases/shortcuts-and-input.md#s37--quick-entry-popup-remains-functional-after-main-window-destroy)) | Upstream `!ut \|\| ut.isDestroyed()` guard at `index.js:515595`. Likely unreachable on this project due to hide-to-tray override of X button |
+
+## Input area
+
+| Element | Location | Expected | Notes |
+|---------|----------|----------|-------|
+| Text input field | Center of popup | Receives focus immediately on open; cursor blinks | — |
+| Placeholder text | Empty input state | Shows guidance like "Ask Claude anything..." | — |
+| Multi-line autosize | Type a long prompt | Input grows downward as text wraps; popup grows with it | — |
+| `Enter` to submit | Press Enter | Sends prompt, closes popup. Prompt must be > 2 chars trimmed (`index.js:515530, 515533`); 1-2 char prompts are silently dropped | Renderer-side keymap; reaches main process via IPC `requestDismissWithPayload()` (`:515409`) |
+| `Shift+Enter` for newline | Press Shift+Enter | Inserts newline, doesn't submit | Renderer-side |
+| `Esc` to dismiss | Press Esc | Closes popup without submitting | Renderer-side; reaches main process via IPC `requestDismiss()` (`:515409`) |
+| Click outside | Click outside the popup window | Closes popup without submitting | Wired in **main process** via the popup's `blur` handler (`Ko.on("blur", () => g3A(null))` at `index.js:515465`) |
+| Paste behavior | Paste rich text | Text-only paste; no HTML residue | — |
+| IME / dead-key composition | Type composed characters | Composition UI renders correctly above the input | Fcitx5/IBus integration is fragile under Electron |
+
+## Submit feedback
+
+| Element | Trigger | Expected | Notes |
+|---------|---------|----------|-------|
+| Submit transition | Press Enter | Popup closes; main window navigates to a **new** chat session ([S31](../cases/shortcuts-and-input.md#s31--quick-entry-submit-makes-the-new-chat-reachable-from-any-main-window-state)). Quick Entry never appends to existing chats — `ynt(e)` at `index.js:515546` always creates new | Upstream calls `mainWin.show()` + `mainWin.focus()` only — no `restore()`, no workspace migration. Behavior on minimized / hidden / cross-workspace main is compositor-dependent |
+| Loading indicator | While prompt is in flight | Brief spinner or fade-out — popup should not appear frozen | — |
+| Error state | Submit when offline / API error | Inline error message; popup stays open so user can retry | — |
+
+## Failure modes to watch for
+
+| Symptom | Likely cause | Diagnose with |
+|---------|--------------|---------------|
+| Popup doesn't appear when shortcut pressed | Global shortcut not registered ([T06](../cases/shortcuts-and-input.md#t06--quick-entry-global-shortcut-unfocused), [S11](../cases/shortcuts-and-input.md#s11--quick-entry-shortcut-fires-from-any-focus-on-wayland-mutter-xwayland-key-grab), [S14](../cases/shortcuts-and-input.md#s14--global-shortcuts-via-xdg-portal-work-on-niri)) | Launcher log; portal `BindShortcuts` outcome |
+| Opaque square frame visible behind UI | Transparent background not respected ([S10](../cases/shortcuts-and-input.md#s10--quick-entry-popup-is-transparent-no-opaque-square-frame)) | KDE compositor settings; BrowserWindow `transparent: true` arg |
+| Popup appears but input doesn't auto-focus | Focus stealing prevention by compositor; race in BrowserWindow `show()` + `focus()` | Wayland focus-request semantics; mutter is most strict |
+| IME composition cursor renders in wrong place | Electron IME integration bug | Try with simpler GTK app to isolate; report upstream Electron issue if reproducible |
+| Popup persists after submit | Close-on-submit IPC missed | Launcher log; DevTools console (if reachable on the popup window) |
+| Popup appears on wrong monitor / wrong workspace | Compositor places frameless windows differently | Test with `xdotool getactivewindow` (X11) before/after |

-
-## Application Logs
-
-Runtime logs are available at:
-```
-~/.cache/claude-desktop-debian/launcher.log
-```
-
-## Common Issues
-
-### Window Scaling Issues
-
-If the window doesn't scale correctly on first launch:
-1. Right-click the Claude Desktop tray icon
-2. Select "Quit" (do not force quit)
-3. Restart the application
-
-This allows the application to save display settings properly.
-
-### Global Hotkey Not Working (Wayland)
-
-If the global hotkey (Ctrl+Alt+Space) doesn't work, ensure you're not running in native Wayland mode:
-
-1. Check your logs at `~/.cache/claude-desktop-debian/launcher.log`
-2. Look for "Using X11 backend via XWayland" - this means hotkeys should work
-3. If you see "Using native Wayland backend", unset `CLAUDE_USE_WAYLAND` or ensure it's not set to `1`
-
-**Note:** Native Wayland mode doesn't support global hotkeys due to Electron/Chromium limitations with XDG GlobalShortcuts Portal.
-
-See [configuration.md](configuration.md) for more details on the `CLAUDE_USE_WAYLAND` environment variable.
-
-### Keyboard Input Doesn't Work (IBus / GTK Input Method)
-
-If typing into the chat does nothing, characters get swallowed, or
-dead-key sequences (e.g. ``` `e ``` → `è`) don't compose, your GTK
-input module integration with the Electron-bundled GTK is broken.
-Common symptoms:
-
-- No characters appear when typing into any text field
-- The first keystroke after focus is dropped, subsequent ones work
-- CJK input methods (IBus, Fcitx) not engaging
-- Compose key / dead-key sequences silently drop
-
-**First step: run `claude-desktop --doctor`.** It checks for the
-common misconfigurations and prints fix commands inline:
-
-- `ibus-gtk3` package missing while `GTK_IM_MODULE=ibus`
-- GTK immodules cache stale (the active module isn't listed by
-  `gtk-query-immodules-3.0`)
-- XWayland session routing IBus through XIM (lossy for some IMEs —
-  set `CLAUDE_USE_WAYLAND=1` to use native Wayland IME)
-- Active value of `CLAUDE_GTK_IM_MODULE` if you've set the override
-
-If `--doctor` is clean but input still misbehaves, switch the
-launcher to a different GTK input module. Set `CLAUDE_GTK_IM_MODULE`
-and Claude Desktop will propagate it as `GTK_IM_MODULE` to Electron
-at startup:
-
-```bash
-# Bypass IBus entirely — uses the X Input Method (XIM) protocol
-CLAUDE_GTK_IM_MODULE=xim claude-desktop
-
-# To make it persistent, export it from your shell profile:
-# echo 'export CLAUDE_GTK_IM_MODULE=xim' >> ~/.profile
-```
-
-Valid values: anything your GTK installation supports (`xim`, `ibus`,
-`fcitx`, `simple`, etc.). When the override is active, the launcher
-logs a line to `~/.cache/claude-desktop-debian/launcher.log`:
-
-```
-GTK_IM_MODULE override: ibus -> xim (via CLAUDE_GTK_IM_MODULE)
-```
-
-**Trade-off:** `xim` is the lowest-common-denominator input module
-and does not support advanced IME features like CJK candidate
-windows or rich compose-key sequences. Only reach for it if your
-real input method (IBus/Fcitx) is broken; if you depend on CJK or
-compose, prefer fixing the IBus/Fcitx integration instead.
-
-### Repeated Electron Crashes / GPU Process FATAL ([#583](https://github.com/aaddrick/claude-desktop-debian/issues/583))
-
-If Claude Desktop crashes repeatedly on launch or shortly after,
-the most common cause on Linux is the Chromium GPU process hitting
-a FATAL exhaustion path. `claude-desktop --doctor` surfaces this
-when `systemd-coredump` shows 3+ Electron crashes in the last 7
-days, pointing at this issue.
-
-Two ways to disable hardware acceleration as a workaround:
-
-1. **In-app:** Settings → toggle hardware acceleration off →
-   restart Claude Desktop. Persists in the upstream config.
-2. **Env var (headless / persists across reinstalls):** set
-   `CLAUDE_DISABLE_GPU=1` in the environment before launching.
-
-```bash
-# One-off:
-CLAUDE_DISABLE_GPU=1 claude-desktop
-
-# Persistent (shell profile):
-echo 'export CLAUDE_DISABLE_GPU=1' >> ~/.profile
-```
-
-When `CLAUDE_DISABLE_GPU=1` is set, the launcher passes
-`--disable-gpu --disable-software-rasterizer` to Electron (see
-`scripts/launcher-common.sh`). This is the same pair of flags
-applied automatically inside XRDP sessions, where software
-rendering is required regardless. Either signal is sufficient —
-the launcher won't stack duplicate flags.
-
-**When to prefer which:** the in-app toggle is friendlier if you
-can reach Settings without the app crashing. Reach for
-`CLAUDE_DISABLE_GPU=1` when the app crashes before you can open
-Settings, when running in environments with no GPU available
-(XRDP, headless CI smoke tests, some VMs), or when you want the
-behavior to persist across reinstalls and config resets.
-
-Tracking issue: [#583](https://github.com/aaddrick/claude-desktop-debian/issues/583).
-
-### AppImage Sandbox Warning
-
-AppImages run with `--no-sandbox` due to electron's chrome-sandbox requiring root privileges for unprivileged namespace creation. This is a known limitation of AppImage format with Electron applications.
-
-For enhanced security, consider:
-- Using the .deb package instead
-- Running the AppImage within a separate sandbox (e.g., bubblewrap)
-- Using Gear Lever's integrated AppImage management for better isolation
-
-### Cowork on Ubuntu 24.04+ (AppArmor Blocks User Namespaces)
-
-Ubuntu 24.04 ships with `apparmor_restrict_unprivileged_userns=1`
-by default, which blocks the unprivileged user namespaces that
-Cowork's bubblewrap sandbox relies on. Symptoms:
-
-- `claude-desktop --doctor` reports `bubblewrap: sandbox probe failed`
-  with `Operation not permitted` in stderr.
-- `~/.config/Claude/logs/cowork_vm_daemon.log` contains
-  `bwrap is installed but cannot create a user namespace`.
-- Cowork sessions hang at "Starting VM..." or loop on reconnect.
-
-Permit user namespaces for `bwrap` via an AppArmor profile (one-time
-setup, requires sudo):
-
-```bash
-sudo tee /etc/apparmor.d/bwrap <<'EOF'
-abi <abi/4.0>,
-include <tunables/global>
-
-profile bwrap /usr/bin/bwrap flags=(unconfined) {
-    userns,
-
-    include if exists <local/bwrap>
-}
-EOF
-
-sudo apparmor_parser -r /etc/apparmor.d/bwrap
-```
-
-After applying the profile, run `claude-desktop --doctor` — the
-bubblewrap probe should pass, and Cowork should start without
-falling back to host-direct.
-
-**Security note:** this grants `/usr/bin/bwrap` the unconfined
-profile plus the `userns` capability. It matches the behavior
-bwrap had on Ubuntu 22.04 and earlier, and on most other distros,
-but is a system-wide change that affects every program invoking
-`/usr/bin/bwrap` (not just Claude Desktop). Review the profile
-against your threat model before applying.

-
-### Cowork: "VM connection timeout after 60 seconds"
-
-If Cowork fails with a VM timeout, the KVM backend is selected but the guest VM cannot connect back to the host via vsock within the timeout window. Common causes:
-
-1. **First-boot initialization** — the guest VM may take longer than 60 seconds on first launch
-2. **vsock driver issues** — the host may be missing the `vhost_vsock` module (`sudo modprobe vhost_vsock`), or the guest initrd may lack `vmw_vsock_virtio_transport`
-
-**Fix:** Force the bubblewrap backend, which provides namespace-level isolation without a VM:
-
-```bash
-COWORK_VM_BACKEND=bwrap claude-desktop
-```
-
-See [configuration.md](configuration.md#cowork-backend) for how to make this permanent.
-
-### Cowork: virtiofsd not found (Fedora/RHEL)
-
-On Fedora and RHEL, `virtiofsd` installs to `/usr/libexec/virtiofsd` which is
-outside `$PATH`. The `--doctor` check detects it there automatically and will
-show `[PASS]`, but the KVM backend spawns `virtiofsd` by name at runtime and
-resolves it through `$PATH` only.
-
-**Fix:** Create a symlink so the KVM backend can find it at runtime:
-
-```bash
-sudo ln -s /usr/libexec/virtiofsd /usr/local/bin/virtiofsd
-```
-
-On Debian/Ubuntu, the same issue can occur with `/usr/lib/qemu/virtiofsd`.
-
-### Cowork: cross-device link error on Fedora tmpfs /tmp
-
-On Fedora, `/tmp` is a tmpfs by default. VM bundle downloads may fail with `EXDEV: cross-device link not permitted` when moving files from `/tmp` to `~/.config/Claude/`.
-
-**Fix:** Set `TMPDIR` to a directory on the same filesystem:
-
-```bash
-mkdir -p ~/.config/Claude/tmp
-TMPDIR=~/.config/Claude/tmp claude-desktop
-```
-
-Or add `TMPDIR=%h/.config/Claude/tmp` to the `Exec=` line in your `.desktop` file.
-
-### Cowork: ENAMETOOLONG on encrypted home (eCryptfs)
-
-Cowork sessions can fail with an opaque `ENAMETOOLONG` error when
-`$HOME` is on a filesystem with a short filename limit. The common
-case is **eCryptfs** — the legacy "encrypted home" option on older
-Ubuntu and Linux Mint installs, which caps individual filenames at
-143 chars because of filename-encryption overhead. Standard
-filesystems (ext4, btrfs, xfs, zfs) cap at 255 chars and are fine.
-
-**Why it happens:** Claude Code creates one directory per session
-under `~/.claude/projects/`, named after the sanitized host CWD. For
-cowork sessions the host CWD is the deeply nested outputs dir under
-`~/.config/Claude/local-agent-mode-sessions/<accountId>/<orgId>/local_<uuid>/outputs`,
-which sanitizes to ~180 chars — fits ext4 but exceeds the eCryptfs
-143-char ceiling.
-
-**Diagnosis:** `claude-desktop --doctor` detects this automatically
-and emits a `[WARN] Filename limit: NAME_MAX=143…` line, plus an
-eCryptfs-specific hint when the filesystem type matches. You can
-also check by hand:
-
-```bash
-df -T $HOME              # look for type "ecryptfs"
-getconf NAME_MAX $HOME   # eCryptfs reports 143; ext4 reports 255
-```
-
-**Workaround:** move Claude's data onto a separate LUKS-encrypted
-ext4 volume (NAME_MAX = 255) and symlink the original paths back.
-`~/.claude/` is the critical one — that's where Claude Code creates
-the long-named per-session dirs that overflow the limit — and
-`~/.config/Claude/` plus `~/.cache/claude-desktop-debian/` are
-relocated alongside it so all Claude state lives on the same volume.
-This keeps the data encrypted at rest while sidestepping the
-eCryptfs filename-length cap.
-
-```bash
-# 1. Create a 2 GB LUKS container
-sudo dd if=/dev/urandom of=/opt/claude-secure.img bs=1M count=2048 \
-    status=progress
-sudo cryptsetup luksFormat /opt/claude-secure.img
-sudo cryptsetup open /opt/claude-secure.img claude-secure
-sudo mkfs.ext4 /dev/mapper/claude-secure
-
-# 2. Mount and move Claude's data in
-sudo mkdir -p /mnt/claude-secure
-sudo mount /dev/mapper/claude-secure /mnt/claude-secure
-sudo chown "$USER:$USER" /mnt/claude-secure
-
-mv ~/.config/Claude /mnt/claude-secure/Claude-config
-mv ~/.cache/claude-desktop-debian /mnt/claude-secure/claude-cache
-# ~/.claude may not exist yet on a fresh install — create the target
-# either way so the symlink below resolves.
-if [ -e ~/.claude ]; then
-    mv ~/.claude /mnt/claude-secure/claude-home
-else
-    mkdir -p /mnt/claude-secure/claude-home
-fi
-
-ln -s /mnt/claude-secure/Claude-config ~/.config/Claude
-ln -s /mnt/claude-secure/claude-cache ~/.cache/claude-desktop-debian
-ln -s /mnt/claude-secure/claude-home ~/.claude
-
-# 3. Verify the filename limit and the symlinks
-getconf NAME_MAX /mnt/claude-secure   # should print 255
-mountpoint /mnt/claude-secure         # confirms the volume is mounted
-readlink ~/.claude                    # /mnt/claude-secure/claude-home
-readlink ~/.config/Claude             # /mnt/claude-secure/Claude-config
-```
-
-**If you've set `CLAUDE_CONFIG_DIR`** (or otherwise reconfigured
-Claude Code to use a directory other than `~/.claude/`), the
-`~/.claude` symlink above doesn't apply — adapt the path to wherever
-your Claude Code config actually lives. The constraint is the same:
-the directory tree where Claude Code creates per-session project
-dirs must sit on a filesystem with `NAME_MAX` ≥ ~200.
-
-**Auto-mount at login** with `pam_mount` so the volume unlocks
-without a manual `cryptsetup open`:
-
-```bash
-sudo apt install libpam-mount
-```
-
-Add a `<volume>` entry to `/etc/security/pam_mount.conf.xml`
-(replace `YOUR_USERNAME` with your login name):
-
-```xml
-<volume user="YOUR_USERNAME" fstype="crypt"
-        path="/opt/claude-secure.img"
-        mountpoint="/mnt/claude-secure"
-        options="" />
-```
-
-`libpam-mount` registers itself with `/etc/pam.d/common-auth` and
-`/etc/pam.d/common-session` automatically on install.
-
-**Notes:**
-- Tested on Linux Mint with LightDM as the display manager.
-- **LUKS passphrase tradeoff:** for `pam_mount` to unlock silently
-  at login the LUKS passphrase must match your login password. That
-  means one compromise unlocks both your session and the encrypted
-  volume — equivalent to the threat surface eCryptfs already had,
-  but worth a deliberate choice. Use a distinct LUKS passphrase if
-  you'd rather be prompted on each unlock.
-- **Confidentiality posture vs eCryptfs.** The LUKS image lives at
-  `/opt/claude-secure.img`, outside `$HOME` and outside whatever
-  encryption envelope eCryptfs gives you. If `pam_mount` ever fails
-  silently — wrong passphrase, mount race at login, profile error —
-  Claude won't start (the symlink targets won't exist), so writes
-  fail loudly rather than landing on plaintext disk. Verify with
-  `mountpoint /mnt/claude-secure` after login if you're unsure.
-- 2 GB is a conservative starting size; the Claude config
-  directory can exceed 500 MB once cowork session history
-  accumulates. Resize if needed.
-- This is a system-wide change that affects login flow — review
-  the pam_mount config against your threat model before applying.

-### Authentication Errors (401)
-
-If you encounter recurring "API Error: 401" messages after periods of inactivity, the cached OAuth token may need to be cleared. This is an upstream application issue reported in [#156](https://github.com/aaddrick/claude-desktop-debian/issues/156).
-
-To fix manually (credit: [MrEdwards007](https://github.com/MrEdwards007)):
-
-1. Close Claude Desktop completely
-2. Edit `~/.config/Claude/config.json`
-3. Remove the line containing `"oauth:tokenCache"` (and any trailing comma if needed)
-4. Save the file and restart Claude Desktop
-5. Log in again when prompted
-
-A scripted solution is also available at the bottom of [this comment](https://github.com/aaddrick/claude-desktop-debian/issues/156#issuecomment-2682547498).

-# Upstream report draft: MCP double-spawn (issue #546)
-
-This is the draft for the upstream bug report covering [#546](https://github.com/aaddrick/claude-desktop-debian/issues/546). Filing target is `anthropics/claude-code` GitHub Issues, with an in-app `/bug` from Claude Desktop as a complement so the report ties to build telemetry.
-
-## Template mismatch note
-
-The `anthropics/claude-code` bug template is built for the Claude Code CLI, not Claude Desktop. Required fields like "Claude Code Version" and "Terminal/Shell" don't apply cleanly. Other Claude Desktop bug reports in the same repo work around this by putting `N/A — Claude Desktop <version>` in the version field and selecting `Other` for terminal (see #43705, #36319, #14807).

-[BUG] Claude Desktop 1.5354.0: stdio MCP servers double-spawn from independent CCD/LAM coordinator registries
-```
-
-## Form fields
-
-### Preflight Checklist
-
-- [x] I have searched existing issues and this hasn't been reported yet
-- [x] This is a single bug report
-- [x] I am using the latest version of Claude Code
-
-### What's Wrong?
-
-I maintain [claude-desktop-debian](https://github.com/aaddrick/claude-desktop-debian) (~2,300 package downloads/day across the last 3 releases), which repackages the Windows Electron build for Linux. I was reading the MCP spawn path in 1.5354.0 and found that stdio MCP servers configured in `claude_desktop_config.json` get spawned twice when both the chat panel and Code/Agent panel are active.
-
-The user-visible symptom is two `node` processes per MCP, both children of the Electron main PID. Killing one disconnects one panel and the other keeps working. They're independent client/server pairs with no failover between them.
-
-The original symptom report came from @communitytranslations against an earlier build (tracked in our repo as #526). I went back and read the bundle to confirm the cause. What I found was different from what we'd previously documented.
-
-CCD wraps the spawn path in a per-key promise queue keyed by server name. It shuts down any prior entry in its global registry Map before respawning. That's correct dedup within CCD. But LAM (`LocalMcpServerManager`) has its own `this.connections` Map and its own `getOrCreateConnection` path. It never consults CCD's registry.
-
-CCD and LAM each maintain independent spawn lifecycle management. They each spawn their own copy of the same MCP server. The double-spawn is structural in the current architecture. Each coordinator legitimately holds its own connection.
-
-There's also a third coordinator class, `SshMcpServerManager`, that follows the same per-coordinator-registry pattern. It uses an SSH transport, so it doesn't contribute to local-node double-spawn directly. Its existence suggests per-coordinator isolated state is a deliberate pattern, not a one-off.
-
-Secondary bug worth flagging while you're in this code. The `child_process.spawn` wrapper does proper signal escalation (end stdin, wait 2s, SIGTERM, wait 2s, SIGKILL). The `utilityProcess.fork` wrapper doesn't. It sends `process.kill()` (default SIGTERM), waits 5s, then calls `kill()` again with the same default signal. No SIGKILL escalation. A built-in-node MCP server that ignores SIGTERM could leak as an orphaned utility process.
-
-### What Should Happen?
-
-One process per stdio MCP server entry in `claude_desktop_config.json`, regardless of how many panels are open. Resource-side that means no more 2x memory and 2x stdin/stdout traffic per server. User-side that means `ps` shows one entry per declared server.
-
-The fix is architectural. CCD and LAM share a registry, or the local-spawn factory dedups at the transport layer, or LAM proxies through CCD when running in-process. Any of those would collapse the duplication.
-
-### Error Messages/Logs
-
-The user-facing log prefixes are stable across releases. Grep `~/.config/Claude/logs/` for:
-
-```
-[CCD]
-[LAM]
-[LocalMcpServerManager]
-[SshMcpServerManager]
-```
-
-For the spawn lifecycle specifically, look for:
-
-```
-"Launching MCP Server: <name>"      (CCD spawn entry)
-"Shutting down MCP Server: <name>"  (CCD shutdown entry)
-"local-mcp-server-cleanup"          (LAM cleanup path)
-```
-
-Two of these per declared MCP server is the diagnostic signal.
-
-### Steps to Reproduce
-
-1. Linux host running Claude Desktop at or near 1.5354.0
-2. Declare at least one stdio MCP server in `~/.config/Claude/claude_desktop_config.json`
-3. Open Claude Desktop, start a session, open the Code/Agent panel and let it initialize fully (the original report waited about 5 minutes)
-4. `ps -ef | grep <server-binary-name>`
-
-Expected: 1 process per MCP. Actual: 2 processes per MCP, both children of the same Electron main PID.

-```
-N/A — this is a Claude Desktop issue. Bundle version: 1.5354.0
-```
-
-### Platform
-
-Anthropic API
-
-### Operating System
-
-Ubuntu/Debian Linux
-
-### Terminal/Shell
-
-Other
-
-### Additional Information
-
-Bundle reference table for 1.5354.0. Symbols rename across releases, so each row has a stable string anchor for re-finding them.
-
-| Role | Symbol in 1.5354.0 | Stable anchor |
-|---|---|---|
-| CCD spawn function | `BPt` | `"Launching MCP Server:"` |
-| CCD shutdown function | `CPt` | `"Shutting down MCP Server:"` |
-| CCD per-key promise queue | `dPt` | called by CCD spawn fn: `await dPt(e, async () => {...})` |
-| CCD server registry Map | `xX` | `.get()` immediately preceding the CCD shutdown log line |
-| Shared transport factory | `oPt` | `"built-in-node"` literal in factory body |
-| LAM manager class | `p0A` | `"[LocalMcpServerManager]"` or `"local-mcp-server-cleanup"` |
-| SSH manager class | `Rde` | `"[SshMcpServerManager]"` or `"ssh-mcp-server-cleanup"` |
-| `utilityProcess.fork` wrapper | `mFr` | constructed in shared factory's `built-in-node` branch |
-| `child_process.spawn` wrapper | `tFr` | constructed in shared factory's default branch |
-
-Extraction commands (verified against 1.5354.0):
-
-```bash
-cd build-reference/app-extracted/.vite/build
-
-# CCD spawn function name
-grep -Pzo 'async function \K\w+(?=\(\w*\)\s*\{(?s).{0,800}?Launching MCP Server)' index.js | tr '\0' '\n'
-
-# Shared transport factory (anchored on the unique 'built-in-node' string)
-grep -Pzo 'async function \K\w+(?=\([^)]*\)\s*\{(?s).{0,400}?built-in-node)' index.js | tr '\0' '\n'
-
-# All coordinator classes following the per-coordinator-registry pattern
-grep -Pzo 'class \K\w+(?=\s*\{(?s).{0,300}?this\.connections\s*=\s*new Map)' index.js | tr '\0' '\n'
-
-# LAM manager class specifically
-grep -Pzo 'class \K\w+(?=\s*\{(?s).{0,500}?local-mcp-server-cleanup)' index.js | tr '\0' '\n'
-```
-
-Two questions where a one-line answer from the team would help us route this downstream:
-
-1. Is per-coordinator isolated state intentional, or is it legacy drift from when each coordinator instantiated its transport inline?
-2. Is the recent extraction of the shared transport factory (`oPt`) the start of a dedup refactor, or incidental cleanup?
-
-If (1) is "intentional," we'll point users at the lockfile workaround as the supported path. If (2) is "in progress," this report saves you the duplicate analysis work.

-## Filing checklist
-
-When you're ready to file:
-
-1. Open https://github.com/anthropics/claude-code/issues/new?template=bug_report.yml
-2. Paste each section above into the matching form field
-3. Submit
-4. Drop the GitHub issue URL as a comment on [#546](https://github.com/aaddrick/claude-desktop-debian/issues/546) so the trail is bidirectional
-
-Note: there is no in-app engineering bug-report path in Claude Desktop. `/bug` and `/feedback` are inert. The Help menu has "Get Support" (routes to the support chat, wrong queue for engineering) and "Troubleshooting" (self-diagnostic — useful for attaching `Copy Installation ID` or `Show Logs in File Manager` output to a GitHub issue, but not a reporting step on its own).
-
-## Voice and authorship
-
-Drafted using the [aaddrick-voice](https://github.com/aaddrick/written-voice-replication/blob/78f178dcf832943bcf1d5a65bf7627c3a20053a6/.claude/agents/aaddrick-voice.md) style profile against the form schema in `anthropics/claude-code/.github/ISSUE_TEMPLATE/bug_report.yml`.

Works on X11 native and KDE Wayland (XWayland), **not** on native-Wayland sessions where the app is running through Ozone-Wayland directly. Per Decision 6, project default is X11; native-Wayland window-state queries are deferred until those tests get added.
 - **T17** is shallow — it intercepts `dialog.showOpenDialog` at the Electron main process level. The integration question "does Claude make the right *portal* call?" is a v2 concern; portal-level mocking via `dbus-next` is sketched in [`docs/testing/automation.md`](../../docs/testing/automation.md) but requires displacing the running portal service or running under `dbus-run-session`.
