Group the review queue into a collapsible section per repo (collapse
state persisted in localStorage), with PRs ordered oldest to newest by
creation date, so a large multi-repo queue is easier to scan.
Add an optional per-PR auto-merge control: a method choice (squash by
default per handbook, merge, or rebase) enables GitHub auto-merge via a
GraphQL mutation, so the PR merges once required checks pass. It only
fires when clicked; nothing merges automatically.
Back this with created_at and node_id from the PR search, two new
nullable store columns added via an idempotent PRAGMA-guarded migration,
and a cheap-gate metadata backfill so already-cached PRs gain node_id
without being re-reviewed. New endpoint POST /api/automerge.
Pre-compute PR reviews so they are ready the moment a PR is opened in
the queue, instead of waiting on an on-demand Fireworks call each time.
A daemon worker polls the queue every POLL_INTERVAL and reviews new or
changed non-draft PRs into a local SQLite cache (gitignored). Change
detection is two-level: skip when the PR's updated_at is unchanged, and
even when it moved, skip the model call when the diff's SHA-256 matches,
so comment-only bumps do not burn tokens. Failed reviews retry up to
MAX_REVIEW_ATTEMPTS with 429 backoff; departed PRs are closed with a
grace window before purge.
Singletons are initialized eagerly in the FastAPI lifespan before the
worker thread starts to avoid an init race; all cache writes are
serialized. New endpoints GET /api/reviews and POST /api/refresh back a
dashboard that polls for status (reviewing/ready/error) and opens a
ready review instantly. Nothing is posted automatically; the human
still decides. Stdlib-only, so no new runtime or test dependencies.
