Reviewed full diff (14 files, +774/-2 lines). No blocking issues found.
Observations (non-blocking)
/metricsbut the FastAPI app does not expose a/metricsendpoint yet. Prometheus will get 404 on scrape. This is consistent with the basketball-api pattern and can be addressed in Phase 7 (observability) by addingprometheus-fastapi-instrumentator.static/index.html). The full booking form from pal-e-appointment will be ported separately._frontend_htmlis cached forever in memory. Acceptable for container deployments where a restart accompanies any file change.Verified

N1.
Dockerfile: NoLABELforBUILD_SHAin final stageThe
BUILD_SHAARG is declared in the final stage and set as an ENV, which is fine. But there is noLABELwith the SHA for image provenance. Consider addingLABEL build.sha="${BUILD_SHA}"so Harbor/registry tooling can trace images to commits. Non-blocking — the ENV is sufficient for runtime.N2.
tests/test_health.py: No test for the/api/bookendpointThe 5 tests cover
/health,/(frontend fallback), and/api/availabilityvalidation. There are zero tests for the/api/bookendpoint, which is the core business logic. Even a validation test (e.g., booking in the past returns 400, end before start returns 400) would add coverage without needing to mock Google Calendar. Non-blocking for this PR since the availability validation tests establish the pattern.N3.
static/index.html: Placeholder frontendThe static file is a placeholder. This is fine for Phase 3 (infrastructure), but worth tracking that a real frontend is needed before Phase 6 verification (appointment booking form loads).
N4.
.woodpecker.yml:pip install .[dev]then separatepip install ruff==0.15.2The
pyproject.tomlalready hasruff>=0.15.0in[project.optional-dependencies] dev. The explicitpip install ruff==0.15.2afterward overrides whatever version.[dev]installed. This works but is slightly redundant — could pinruff==0.15.2directly in pyproject.toml dev deps instead. Non-blocking since the pinned CI version is the one that matters.N5.
main.py: Global mutable_frontend_htmlcache with no invalidationThe
_frontend_htmlvariable is cached on first read and never cleared (except in the test). If the static file is updated at runtime, the app serves stale HTML until restart. Acceptable for a container deployment (restart = new container), but worth noting.SOP COMPLIANCE

BLOCKERS
1. ServiceMonitor scrapes
/metricsbut no/metricsendpoint existsk8s/servicemonitor.yamlconfigures Prometheus to scrape/metricsevery 30 seconds:However,
src/gcal_scheduler/main.pyonly defines these routes:/health,/,/api/availability,/api/book. There is no/metricsendpoint. This will cause Prometheus to log scrape failures (HTTP 404) every 30 seconds and generate noisy alerts.Fix options:
prometheus-fastapi-instrumentatororstarlette-exporter-- this gives real request metrics.servicemonitor.yamlfromk8s/kustomization.yamland delete the file. Add it back when a metrics endpoint is implemented.Option (b) is simpler and avoids adding a dependency for Phase 3. The ServiceMonitor can be added in Phase 7 (Observability).
NITS
1. Dockerfile: no USER directive
The Dockerfile does not include a
USER 1000directive. The k8s deployment correctly setsrunAsNonRoot: trueandrunAsUser: 1000via securityContext, so the container will run as non-root in practice. However, addingUSER 1000in the Dockerfile is a defense-in-depth best practice -- it ensures non-root execution even if someone runs the image outside k8s (e.g., localdocker run).Suggested addition before
CMD:Non-blocking since k8s securityContext already enforces this.
2. Frontend HTML caching is permanent
main.pycaches_frontend_htmlin a module-level global on first request. Once cached, the file is never re-read. This is fine for production (static file doesn't change at runtime), but worth noting for development. Non-blocking.3. Test line lengths
tests/test_health.pylines 33, 40, and 46 are long single-line calls. These passruff formatat line-length 120, so they are compliant. No action needed -- just noting for readability.SOP COMPLIANCE

One blocker: the ServiceMonitor will scrape a non-existent
/metricsendpoint, causing continuous 404 errors in Prometheus. Either add a metrics endpoint or remove the ServiceMonitor until Phase 7.Everything else looks solid -- good multi-stage Dockerfile, correct k8s conventions, proper security context, well-structured application code with validation and error handling, and full SOP compliance.
