feat(pr-review): before-merge ticks that survive pushes, a reminder at merge, and a detector eval - #1351
Conversation
…t merge, and a detector eval The Before merge checklist rendered task boxes nobody read: each review posts its own comment, so a box ticked on one push was gone on the next. - Steps are tracked per pull request in pr_review_merge_steps under a stable key (mergeStepKey). Each review reconciles against them: ticks carry, a reworded manual step keeps its tick, a step the head no longer needs goes obsolete. A reviewer step that replaces a detected one keeps its kind. - Every task carries a hidden key tag. An edit of the App's review comment by a person that changes a tagged box becomes a pull-request-checklist job and is recorded as done or reopened; the App's own re-renders change no box. - A merge with open steps posts one comment listing them, claimed first so a redelivered close posts nothing. - The detectors are scored on 36 real pull requests in bun run test (recall per kind, precision, noise on pull requests that needed nothing). review:checklist --snapshot adds a case, ruling on names at the base commit. The corpus found that names held in *_CONFIG constants were never read (the Slack credentials of #993); that pattern is now detected.

…nct keys, a reminder that retries - A review whose diff could not be read no longer marks every tracked step obsolete: an unread diff says nothing about what the head produces. - mergeStepKey no longer cuts a reviewer step's slug to a shared prefix or empties a title with no ASCII word: those carry a hash of the full title. - The merge reminder releases its claim when the post fails or no provider is found, so a redelivered close event posts it.
Maple review🟢 Confidence 9/10 · safe to merge Before-merge steps are now stored per pull request, so a tick survives the next review comment, and a merge with open steps posts one reminder. The two open defects are fixed at this head; safe to merge.

Why
#1339 added a "Before merge" task list to every review comment, but the boxes were decoration: each review posts its own comment, so a box ticked on one push was gone on the next, and nothing read the ticks. The point of the list is to not forget setup (new secrets, migrations) before merging, so it has to remember what was done and say something when a PR merges with steps still open.
What changed
