Requesting the forge account `review-classifier` as a reviewer now runs the
repo's rules against the PR and posts the result as that account's review,
on the head commit the run read. A push starts no run; only a fresh review
request does.
- An instance-wide `pull_request_review_request` system hook delivers to
`/webhook/forge/review-request`. A request for any other reviewer, or a
removed request, does nothing.
- The controller reads the PR, loads the rules with the same reader as
`GET /api/review-classifier/rules`, sends one request on the try-out
subject, and posts APPROVED or REQUEST_CHANGES with the table as the body.
- With no clean verdict (PR or rules don't load, the run fails, or any
classification has no answer) it posts a COMMENT saying why, never an
approval. The event is one function, `no_clean_verdict_event`.
- Table cells are flattened, markup-escaped, and every `@` gets a
zero-width space, so a model's reason can't break the table or mention
anyone.
- At most two requested reviews run at once; the rest wait in memory.
- The account is minted the way hive accounts are: a five-minute pass
queues a `MintClassifierForgeToken` node when the token at
`swarm/services/review-classifier/forge/token` is missing or stale. The
token is `write:repository`. The controller's bao policy gains that leaf
(create/read/update), pinned in module-eval bao-grants. The classifier
never sees the token.
The account gets no repo access automatically; a repo admin adds it by
hand. A re-request retires the account's earlier review: Forgejo clears
`official` on a reviewer's earlier reviews when it is requested again
(models/issues/review.go AddReviewRequest, v16.0.5), and approvals and
rejection blocks count official reviews only.
