/version went null after a deploy — the exact "service cannot name its own
commit" defect this project was built to prevent, caught by its own honesty
check.
Cause: the sed replaced "" with "" (a no-op when COMMIT_SHA is empty) and the
grep then matched that same empty string, so the guard verified nothing. A build
with no COMMIT_SHA passed and shipped a container reporting commit_sha: null.
Now the build fails loudly instead.
Second cause of the stale deploy, and it was mine: an earlier `git commit
--amend` + force-push rewrote history the Veron deploy checkout was already
sitting on, leaving it divergent so `git pull -q` failed SILENTLY (-q hid
"Need to specify how to reconcile divergent branches"). Two lessons: do not
force-push a branch a deploy checkout tracks, and do not pull with -q in a
deploy script.

Strand G0 complete and VERIFIED against real Postgres, not asserted.
- FastAPI plane, fail-closed provider seams, repair-pointer error taxonomy
- migration 001: all 10 tables incl. repo_type NOT NULL and model_cards (I-7)
- 17 invariant tests, ruff clean, vocabulary audit clean
Two bugs found by RUNNING it that review would not have caught:
1. SQLAlchemy Enum persists .name, not .value — so RepoState.deleted_soft
and CreatedVia.imported would have written labels migration 001 never
declared, failing at runtime rather than at review. Pinned via
values_callable.
2. op.create_table asks each Enum to emit its own CREATE TYPE with no
checkfirst, so the second reference raised DuplicateObject and the
migration died halfway. Types are now created once, referenced with
create_type=False.
Proven live, with the hostile env var set:
- I-12: COMMIT_SHA=deadbeef... in the environment, /version reports real HEAD.
That env pin is the documented root cause of nine sibling services
misreporting their commit; here it is structurally ignored.
- I-8: three unconfigured providers -> status degraded, HTTP 503, each saying
'refusing to report healthy'. No mock, no false green.
- G0.4: upgrade -> downgrade -> upgrade round-trip clean (10 -> 0 -> 10).
