- backend/tests: 74 hermetic tests (no network, no repo data//logs/ writes) covering grid snapping/round-trips, grading percentiles/bands/windows/ dry streaks, the places index (norm, one-edit matchers, search, corrections), the derived store (token validity, cache=False, degraded mode), and route-level API tests over a faked climate layer — routing, validation, ETag/304 revalidation, store replay, the /cell bundle, and the v1/v2 aliases. The API tests would have caught the /place AttributeError regression. - requirements-dev.txt + make test (venv prefers uv-pinned 3.12, matching deploy-dev.sh — pyarrow wheels stop at 3.12 and some pyenv builds lack sqlite). - CI: extract the build job into a reusable build.yml, add the test run and an API health probe (page-only curl can't catch route wiring faults); deploy-dev.yml now runs the same build gate before deploying direct pushes, which previously deployed with no CI at all. - Deploys serialize under one dev-lan-deploy concurrency group across both workflows (previously per-PR groups could interleave two deploys to the same checkout), and are never cancelled mid-restart. - deploy-dev.sh health check also probes /api/v2/place — best-effort externals mean a failure there is a genuine server bug.
