feat(triage): Phase 4 sub-PRs 3+4 — regression_of + edit-during-triage (#472)
* feat(triage): Phase 4 sub-PRs 3+4 — regression_of + edit-during-triage Bundles the two remaining Phase 4 sub-phases. Both are small workflow additions that build on infrastructure already in place: the Phase 1 input snapshot (updated_at captured at Stage 1) and the Phase 1 classify.json's regression_of field. regression_of end-to-end (Stage 3b + Stage 4 + Stage 6) - New step `Validate regression_of` between drift-check and fetch. Runs only when classify set regression_of to non-null. - Validation: PR exists in this repo; PR is merged; PR's mergedAt precedes issue's createdAt. Any failure clears to null with a logged note and the issue proceeds as a regular bug. - Valid regression → `gh pr diff` fetched (capped at 4000 lines) and inlined into the investigate prompt as primary context. Tells the investigator to start the search in the PR's changed files. - Same diff inlined into the review prompt, wrapped as pipeline_data, so the reviewer can check whether findings land inside the named PR's changed files. - Handles the spec's "cleared to null with logged note" requirement for upstream Electron PRs that aren't in this repo. Edit-during-triage detection (Stage 8 post-processor) - New step between 8a/8c post-processors and Apply labels. Runs for every variant. - Re-fetches issue.updated_at live and compares against the Stage 1 input_snapshot.updated_at. - On mismatch: appends a `⚠ This issue was edited after triage began. ...` disclaimer to the rendered comment, pointing at input_snapshot.json as the audit trail. - Catches inject-then-delete attacks (inject instructions, wait for bot, delete before a human reads) and honest mid-triage edits that would make the comment stale. Step summary gains `regression_of validated` row. With this PR, Phase 4 is complete: 8c enhancement-design, suspicious- input tells, regression_of, edit-during-triage detection are all live. All terminal paths (bug / enhancement / question / duplicate / needs-info / not-actionable / suspicious) flow through the pipeline end-to-end per spec. Co-Authored-By: Claude <claude@anthropic.com> * docs(triage): correct stale sort -u reference in date-compare comment The comment above the ISO 8601 date check referenced `sort -u`, which isn't used in the code. Rewrite to describe what the code actually does: `[[ > ]]` on the raw timestamp strings, which is valid because ISO 8601 sorts lexicographically as chronologically. Also re-orient the prose around the invalid case (mergedAt AFTER createdAt), matching the branch that the following `if` takes.
