Status: Complete

Implemented batched GraphQL fetching for run_review_sweep per the spec.

Changes:

• src/github/graphql.rs (new): batch_pr_status/batch_pr_status_chunked — one aliased GraphQL query per up-to-40 PRs (GRAPHQL_PR_BATCH_SIZE), reusing the exact client.request("POST", "/graphql", ...) pattern already established by pulls::resolved_review_comment_ids. Fetches merged/mergeable/mergeStateStatus/check-runs/labels for every PR in one round trip; chunks soft-fail independently so one bad chunk doesn't blind the whole sweep.
• src/worktree/mod.rs: split pr_ci_status_impl's post-fetch decision tree into a shared decide_from_checks helper, then added pr_ci_status_from_batch as a sibling that runs the same decision logic against BatchPrData instead of a REST PullRequest — the decide-what-it-means logic exists in exactly one place regardless of fetch path. Also split update_stale_branch's GitHub call into a mockable update_branch_pr, mirroring the existing merge_approved_pr test seam.
• src/supervisor.rs: run_review_sweep now partitions in-review items into numbered (have metadata.pr.number, batch-eligible) and unnumbered (legacy items, predate that field — fall back to the old per-item REST path). Numbered items go through one batch_pr_status_chunked call per project per tick instead of 1-2 REST calls each. Extracted the per-item decide-and-mutate match arms into handle_pr_status so both paths share identical mutation logic.

Race/idempotency handling: Verified rather than newly built — promote_merged_item→item_check_merge already re-verifies live merge state before promoting (DB-state-drift-safe), and merge/update-branch are GitHub-side idempotent operations that already fail cleanly on a repeat call. Added explicit tests pinning that invariant (update_branch_pr_returns_false_and_does_not_panic_when_already_up_to_date) since it previously existed only for merge. Self-repair dispatch's existing job_in_flight + claim-liveness gate is untouched and still the authority for that one non-idempotent mutation; documented why merge/update-branch don't need the same claim check (they're safe via GitHub's own atomicity, claim-liveness only matters for the "start new work" branch).

Tests: 9 new graphql.rs unit tests (aliasing, enum/case normalization, error handling, chunk-splitting), 5 new worktree tests (pr_ci_status_from_batch decision-tree parity, update_branch_pr idempotency), 1 new supervisor_tests.rs regression test exercising the new numbered/batch code path. Full suite: 1653 passed, 1 unrelated pre-existing failure (mcp_prompts::tests::optimize_review_returns_full_skill_body, fails identically in isolation, touches none of the files in this change — a skill-body-content assertion unrelated to GitHub/review-sweep code).

Concern: the actual end-to-end request-count reduction inside run_review_sweep itself isn't verifiable by test — Client::new() has no test-injectable base URL, so all existing run_review_sweep tests (before and after this change) use a remote-less throwaway_repo() and never hit real HTTP. The batching math is proven at the graphql.rs unit level instead (1 query per ≤40 PRs, confirmed by test).

📝 Walkthrough

Walkthrough

The change adds batched GraphQL retrieval for pull-request status, labels, and checks. The review sweep uses batched data for numbered pull requests, retains REST fallback for unnumbered items, and shares CI classification and status handling.

Changes

Pull-request status batching

Layer / File(s)	Summary
GraphQL batch retrieval src/github/graphql.rs, src/github/mod.rs	The GitHub module adds aliased GraphQL requests, chunking, response parsing, error handling, and tests for pull-request status data.
Shared CI status classification src/worktree/mod.rs	REST and GraphQL check data use shared classification. Batched results cover merged, behind, passing, failing, and pending states.
Review-sweep integration src/supervisor.rs, src/supervisor_tests.rs	The supervisor batches numbered pull requests, keeps REST handling for unnumbered items, and routes both paths through shared status handling. The tests cover unresolved repository remotes.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to fc155

The new batched status path can misclassify pull requests when check failures or approval labels fall beyond the fetched limits, potentially allowing an unsafe merge or blocking an eligible one. Merge should wait until pagination is handled or incomplete results are treated conservatively.

Preserve pagination state before classifying PR status.

pr_subquery requests only the first 20 labels and 100 statusCheckRollup.contexts, while parse_batch_pr discards pagination metadata. A failing CheckRun after context 100 can therefore yield PrCiStatus::Passing; an approval label after label 20 can also be omitted and prevent merge_if_approved. Paginate these connections or return Unknown for incomplete results. Add 101-check and 21-label fixtures.
