Closes #2970 (track 2).

A platform agent (concierge) that reaches /registry/register without a seeded MODEL workspace_secret must not be marked online. The MISSING_MODEL gate in prepareProvisionContext is the primary defense, but if a model-less/identity-less concierge somehow boots on a path that bypasses that gate (e.g. an old or generic image), this second-layer guard marks the workspace failed instead of letting it serve users as generic Claude Code.

Changes

• Add platformAgentHasModelSecret + markWorkspaceFailed helpers in registry.go.
• In Register, after delivery-mode resolution, gate kind=platform rows on the presence of a MODEL workspace_secret; on failure broadcast WORKSPACE_PROVISION_FAILED and return 400.
• Use existingState.ExistingKind (already fetched for diagnostics) so no extra DB round-trip is needed.
• Update TestRegister_AllowsAlreadyPlatformReRegister and add TestRegister_PlatformAgentMissingModelSecret_FailsClosed.

Test plan

• go test -run TestRegister_ ./internal/handlers/ -count=1 ✅
• go test -run TestResolveDeliveryMode ./internal/handlers/ -count=1 ✅
• go test ./internal/handlers/ -count=1 ✅ (full suite, ~38s)

Scope note

This addresses the molecule-core register-time fail-closed check identified in #2970. It does not replace the platform-agent image/entrypoint deployment work (track 1) or the full conciergeIdentityPresent probe work being handled in the #2955 chain.

Closes #2970 (track 2). A platform agent (concierge) that reaches `/registry/register` without a seeded MODEL workspace_secret must not be marked `online`. The MISSING_MODEL gate in `prepareProvisionContext` is the primary defense, but if a model-less/identity-less concierge somehow boots on a path that bypasses that gate (e.g. an old or generic image), this second-layer guard marks the workspace `failed` instead of letting it serve users as generic Claude Code. ### Changes - Add `platformAgentHasModelSecret` + `markWorkspaceFailed` helpers in `registry.go`. - In `Register`, after delivery-mode resolution, gate `kind=platform` rows on the presence of a `MODEL` workspace_secret; on failure broadcast `WORKSPACE_PROVISION_FAILED` and return `400`. - Use `existingState.ExistingKind` (already fetched for diagnostics) so no extra DB round-trip is needed. - Update `TestRegister_AllowsAlreadyPlatformReRegister` and add `TestRegister_PlatformAgentMissingModelSecret_FailsClosed`. ### Test plan - `go test -run TestRegister_ ./internal/handlers/ -count=1` ✅ - `go test -run TestResolveDeliveryMode ./internal/handlers/ -count=1` ✅ - `go test ./internal/handlers/ -count=1` ✅ (full suite, ~38s) ### Scope note This addresses the molecule-core register-time fail-closed check identified in #2970. It does not replace the platform-agent image/entrypoint deployment work (track 1) or the full `conciergeIdentityPresent` probe work being handled in the #2955 chain.

fix(registry#2970): fail-closed platform-agent register gate on missing MODEL secret ... 07448d132f

A platform agent (concierge) that reaches /registry/register without a
seeded MODEL workspace_secret must not be marked online. The MISSING_MODEL
gate in prepareProvisionContext is the primary defense, but if a model-less/
identity-less concierge somehow boots on a path that bypasses that gate, this
second-layer guard marks the workspace failed instead of letting it serve
users as generic Claude Code.

- Add platformAgentHasModelSecret + markWorkspaceFailed helpers.
- In Register, after delivery-mode resolution, gate kind='platform' rows on
  the presence of a MODEL workspace_secret; on failure broadcast
  WORKSPACE_PROVISION_FAILED and return 400.
- Use existingState.ExistingKind (already fetched for diagnostics) so no
  extra DB round-trip is needed.
- Add/update tests.

Refs #2970 track 2. Does not close the deployment/identity track; that is
handled by the #2955 image-entrypoint work.

APPROVE (qa-review + security-review) @ 07448d13 — correct fail-closed identity gate, green, well-tested. IMPORTANT cross-check: this is NOT complementary to #2972 — they COLLIDE. See the collision note at the end; merge THIS one, not both.

5-axis / per-PR:

• (a) fail-closed correct ✅ — Register (registry.go:527): for payload.Kind==platform || existingKind==platform, calls platformAgentHasModelSecret; on absence → markWorkspaceFailed (sets status=failed, broadcasts WORKSPACE_PROVISION_FAILED w/ code PLATFORM_AGENT_IDENTITY_GATE) + logRegister400Reason + 400 "platform agent identity incomplete" + return. A model-less concierge is actively rejected AND marked failed AND broadcast — never online-routable. Lookup error → 500 (also fail-closed, not silent-pass).
• (b) no over-block ✅ — a platform agent WITH the MODEL secret → hasModel=true → skips the gate → normal online registration. The legit path is exercised in the existing test (EXISTS→true). Also correctly catches the re-register case via existingKind==platform.
• (c) tests genuine ✅ — TestRegister_PlatformAgentMissingModelSecret_FailsClosed: mocks kind=platform + SELECT EXISTS(... key='MODEL')→false, asserts the UPDATE ... status=failed fires (WithArgs(wsID, AnyArg, StatusFailed)), the broadcast happens, and w.Code==400. The happy path (EXISTS→true→online) is also covered.
• (d) no #2966 regression ✅ — this gate enforces exactly what #2966's ensureConciergeModel seeds (the MODEL workspace_secret). A correctly-provisioned concierge (post-#2966) has the secret → passes; only the model-less bug-state is rejected. Complementary to #2966, not conflicting. (Edge to be aware of: register must not race ahead of the seed-persist; the seed is at provision-time before boot, so ordering holds.)

COLLISION with #2972 (the decisive cross-check): the dispatch framed #2972 as "handlers/readiness layer" and this as "registry layer" — but BOTH modify the same Register handler in registry.go for the same condition (platform agent + missing MODEL). #2972 sets effectiveStatus=failed in the upsert (inserts a failed row); this PR rejects with 400 + marks-failed + broadcasts. They are competing implementations, not defense-in-depth — they will merge-conflict, and running both would double-gate. Recommend merging THIS one (#2973): it's green, rejects cleanly, broadcasts the identity-gate event, handles re-register, and doesn't break existing tests — whereas #2972's CI is red (10 broken Register tests). Close/supersede #2972.

Approve. (Prod gate → driver sign-off too; 2nd genuine from Researcher/CR3.)
