Summary

This PR covers two stories for Danielle (Tech Lead), recorded in ADR-056:

1. Suggest links from explicit references such as "Closes #184" ("Design the Box" F2 / MVP scope).
2. Move a wrongly linked pull request to the correct requirement (scenario "Changing a requirement after its code was merged").

Problem

• Every pull request had to be linked by hand, even when its description already said which issue it closes. ADR-036 reserved source = suggested, but nothing could create a suggestion.
• A link on the wrong requirement could only be removed and re-added by hand. Nothing connected the two changes, so neither requirement's history showed what had happened.

Solution

Suggestions

• Finding them: for each issue linked to the requirement, the API reads the issue's GitHub timeline for pull requests of the connected repository. It keeps those whose description uses a closing keyword (close, fix or resolve in GitHub's forms) before #N, owner/name#N or the issue's address. A plain mention doesn't count. No AI is involved.
• When it runs: on Find suggestions (POST .../evidence/suggestions/scan) and on Refresh from GitHub. No webhook is added, so ADR-032 stands.
• Not evidence: suggestions live in requirement_evidence_suggestions. The evidence list, evidenceCount, review snapshots, "outdated" and Evidence complete don't read that table. The description text is neither stored nor logged, only the reference found, such as "Closes #184".
• Deciding: any member can confirm or reject.
  • Confirm reads the pull request from GitHub and links it like any link, with source = suggested.
  • Reject means it is never suggested again for that requirement, though it can still be linked by hand.
  • Each decision is kept on the row with who and when, and as a confirmed or rejected event in the link history.
• Staying current: a complete read drops undecided suggestions it no longer finds, and linking a pull request by hand drops its suggestion.

Moving a link

• POST /requirements/{id}/evidence/{evidenceId}/move moves any linked item to another active requirement of the project, in one transaction under the team lock.
• The link keeps its ID, so decisions on both requirements become outdated. linkedBy and linkedAt become the mover and the time, and source becomes manual.
• Each requirement's history gets an event naming the other requirement (moved_out, moved_in).
• Release comparisons follow the link.
• A pull request moved away is recorded as rejected for the requirement it left. Otherwise its closing reference would suggest it straight back.

SaveLinkAsync was split out of Link so confirming reuses the same read-and-save path.

Migrations

RequirementEvidenceSuggestions

• Adds requirement_evidence_suggestions, with RLS on and PUBLIC/anon/authenticated grants revoked.
• Widens requirement_evidence_events.action and adds a nullable other_requirement_id.
• Generated by scripts/generate-requirement-evidence-suggestions.mjs. The SQL is in docs/schema/requirement-evidence-suggestions*.sql.
• CI applies it after merge (ADR-044). Please don't apply it to Supabase by hand first. The running API only writes added and removed, which stay valid.
• Rollback: dotnet ef database update RequirementEvidenceEvents --project app/api, or the rollback script. It drops the table, losing every suggestion. In the history, moves become a removal and an addition, confirmations become additions, and rejected events are deleted, so rejected pull requests could be suggested again. Links stay.

There are no environment or configuration changes.

Validation

• npm test: 407 passed. This includes the web build, the Release API build, and the Docker Postgres schema suite.
• npm run lint, npm run typecheck, dotnet format app/api --verify-no-changes, dotnet ef migrations has-pending-model-changes (none) and git diff --check all pass.
• New and updated tests:
  • tests/schema/evidence-suggestions.spec.ts (new; fake GitHub on 5130, API on 5131) covers:
    • every closing-reference form, and what must not match
    • suggestions not counted as evidence
    • confirm and reject, and decisions that stand
    • linking by hand, edited references, refresh, and items gone from GitHub
    • access, archived projects (also while waiting for the team lock), disconnected repositories, and GitHub failures
    • moves, refusals, and release comparison after a move
    • the migration's constraints, RLS and rollback
  • tests/e2e/evidence.spec.ts: the suggestion and move flows, plus a failed scan, a refused decision and a refused move.
  • tests/api/project-data.spec.ts: parsers and history text.
  • Migration-history counts went up by one in reviews.spec.ts, evidence.spec.ts and github-repository.spec.ts.

Screenshots

Known limitations

• There are no webhooks, so a new pull request appears only after someone presses Find suggestions or Refresh.
• Only pull request descriptions are read, not commit messages or comments, and only for issues linked to the requirement.
• Refresh makes one more GitHub call per linked issue and fails if that read fails.
• The timeline is read up to 500 events per issue.
• Tests use a stand-in for GitHub, so the real timeline format isn't exercised. Please try it once on a real repository.
• The scaffold Suggestions page stays a placeholder; suggestions are on the requirement page.

Decisions: ADR-056, plus a note on ADR-036. Full detail is in docs/HANDOFF.md.

Merge Risk: Moderate · previous review 4a61d

Suggestions can disappear or reflect removed issue links, and concurrent moves can leave incorrect histories or release comparisons. Moves also bypass the disconnected read-only restriction and overwrite earlier suggestion decisions. Resolve these consistency issues before merging.

Timeline results are filtered using the saved owner/name rather than the repository ID used for the request. After a repository rename or transfer, valid mentions may be discarded and refresh may remove all pending suggestions.

Find suggestions returns no matching pull requests, and refresh removes existing pending suggestions despite unchanged repository identity and closing relationships.

This can occur when: The connected GitHub repository is renamed or transferred without reconnecting it; GitHub returns cross-reference repository_url values using its current name.

Add a scan test for a second timeline page.

The scan fixtures fit on one page, so they would not detect a regression that stops after page one. Add 99 plain mentions before a closing reference and assert that the page-two reference becomes a suggestion.

Review comments at @app/api/GitHub/EvidenceChangeEndpoints.cs:
- Line 333: Update the move-handling logic near the tuple assignment so it
preserves the original suggestion status, decision actor, and decision time for
confirmed or previously rejected pull requests. Record the move rejection
separately, using the existing mechanism if available, while keeping the pull
request suppressed.
- Around line 200-203: After acquiring the team lock in the move flow, recheck
that the evidence link still belongs to the original source requirement; reject
the move if it has changed before recording either event or updating the link.
Locate the lock acquisition and `Record` calls in the move handler, and preserve
the existing event and update behavior when the source still matches.
- Line 61: The Changed recheck path must not save suggestions based on a stale
issue-link snapshot. Update the Recheck.Changed handling in
EvidenceChangeEndpoints to reacquire the team lock, compare the current
issue-link snapshot with the one used during the timeline scan, and abort the
scan if the links changed; preserve the existing save flow when they match.
- Around line 169-170: In the move endpoint’s flow around the `repository`
lookup, return `NoRepository()` before moving the link or changing its
attribution when no repository is connected. Preserve the repository recheck
under the team lock to prevent a disconnection during the move from bypassing
the restriction.
- Around line 172-175: Revalidate the target release snapshots in the
evidence-move flow around ReadContentsAsync after acquiring the team lock; if
they are stale, reject or retry the move instead of overwriting the existing
release comparison. Preserve the current contents-reading behavior for valid
moves.

Review comments at @app/api/GitHub/GitHubClient.cs:
- Line 604: Update the timeline scan that returns
GitHubResult<List<GitHubMention>> to propagate whether any issue timeline was
truncated, including reads beyond page five, and have the downstream pruning
flow skip pruning when that signal indicates an incomplete read; retain normal
pruning for complete scans.
