Make /health report the precise git SHA the container was built from,
so 'is the live service current?' can be answered without ambiguity.
0.2.0 was too coarse to trust as a 'live is current' signal — many
commits share the same __version__.
Three layers:
1. /health endpoint (src/atocore/api/routes.py)
- Reads ATOCORE_BUILD_SHA, ATOCORE_BUILD_TIME, ATOCORE_BUILD_BRANCH
from environment, defaults to 'unknown'
- Reports them alongside existing code_version field
2. docker-compose.yml
- Forwards the three env vars from the host into the container
- Defaults to 'unknown' so direct `docker compose up` runs (without
deploy.sh) cleanly signal missing build provenance
3. deploy.sh
- Step 2 captures git SHA + UTC timestamp + branch and exports them
as env vars before `docker compose up -d --build`
- Step 6 reads /health post-deploy and compares the reported
build_sha against the freshly-built one. Mismatch exits non-zero
(exit code 6) with a remediation hint covering cached image,
env propagation, and concurrent restart cases
Tests (tests/test_api_storage.py):
- test_health_endpoint_reports_code_version_from_module
- test_health_endpoint_reports_build_metadata_from_env
- test_health_endpoint_reports_unknown_when_build_env_unset
Docs (docs/dalidou-deployment.md):
- Three-level drift detection table (code_version coarse,
build_sha precise, build_time/branch forensic)
- Canonical drift check script using LIVE_SHA vs EXPECTED_SHA
- Note that running deploy.sh is itself the simplest drift check
219/219 tests passing.
