core's providers-registry mirror carried a STALE vertex entry: auth_mode third_party_anthropic_compat, base_url_template null, no endpoint_vars or wire_model_prefix (registry Fingerprint e457249eb0fd77a2). The CP SSOT (molecule-controlplane internal/providers/providers.yaml, Fingerprint 9d129c96c9df9689) carries the correct keyless-WIF vertex entry. Byte-sync the CP canonical providers.yaml into core's synced copy: - vertex: auth_mode wif_adc; templated Vertex endpoint https://{location}-aiplatform.googleapis.com/v1beta1/projects/{project}/locations/{location}/endpoints/openapi; endpoint_vars MOLECULE_VERTEX_LOCATION/_PROJECT; wire_model_prefix google/ - header schema-doc comments for the new fields (auth_mode wif_adc, base_url_template placeholders, endpoint_vars, wire_model_prefix) that were not synced when the vertex data was first mirrored Regenerate registry_gen.go via cmd/gen-providers — core Fingerprint now equals CP's 9d129c96c9df9689 and the generated artifact is byte-identical to CP's. Bump canonicalProvidersYAMLSHA256 to the re-synced canonical sha (58bc38648674e77c6ffa6ffe41e911bec8c68da56d028550f2e39dedc4aa25ae). Diff is isolated to vertex; all other providers/runtimes/models unchanged. verify-providers-gen (-check) OK; provider tests green.

944652b13c.5-axis / drift review:
verify-providers-genis green and registry_gen.go fingerprint is regenerated from e457249eb0fd77a2 to 9d129c96c9df9689.CI / all-requiredandverify-providers-genare green. The red staging full-lifecycle context is non-required and outside this registry drift fix.REQUEST_CHANGES after current-head no-regression review at
944652b13c.Gating test verified fail-closed: yes. sync_canonical_test.go pins the embedded providers.yaml SHA and uses t.Fatalf on mismatch, so a partial/hand edit or unsynced canonical copy fails hard. verify-providers-gen is also success, and registry_gen.go fingerprint is 9d129c96c9df9689, matching the CP canonical fingerprint called out for this drift fix.
Code/diff scope: the diff is limited to the vertex provider row sync (auth_mode wif_adc, templated Vertex endpoint vars, wire_model_prefix), regenerated registry_gen.go, and the canonical YAML SHA bump. No new fail-open path found in the drift guard.
Blocker: CI is not green on the current head. Combined status is failure: E2E Staging SaaS full lifecycle / Platform Boot and E2E Staging SaaS are failing, and governance gates (qa-review/security-review/sop-tier/checklist) are also red. Per the no-regression review criteria, I cannot approve until the current head is green or those failures are resolved/clearly rerun green.
APPROVED after re-assessment on current head
944652b13c.Required-context check: the three currently required branch-protection contexts are green: CI / all-required, E2E API Smoke Test, and Handlers Postgres Integration. The remaining red E2E Staging/governance statuses are non-required pre-#2331 and are tracked separately.
Diff/gate review remains clean: core's synced providers.yaml updates the vertex row to the CP canonical wif_adc/endpoint_vars/wire_model_prefix shape; registry_gen.go fingerprint is 9d129c96c9df9689, matching the CP canonical fingerprint; verify-providers-gen is green; sync_canonical_test.go is a hard fail-closed SHA pin using t.Fatalf on drift. No new fail-open path found.
