+## Admission source
+
+The model API authenticates the caller with the existing static token registry
+only to identify the caller and retain the existing static scopes. For the
+exact caller, release:candidate and governed-task:project are not permanent
+static-token grants. The model API asks the Unix-socket Owner broker to
+rehydrate the requested durable capability.
+
+The broker reloads the durable policy and revocation file on every request,
+checks the exact caller, requested capability, policy constraints, optional
+expiry and revocation state, and rejects all capabilities outside the durable
+policy. It never uses a release-worker identity or credential.
+
+## Projection lifecycle and ACK semantics
+
+The server-side flow is:
+
+durable Owner policy
+  -> exact caller and capability validation
+  -> caller projection rows for the policy capabilities
+  -> in-memory short-lived credential generation
+  -> projection ACKED / credential REHYDRATED
+  -> model API admission
+  -> Bridge governed-task admission and execution envelope
+
+The existing caller_projections table stores only projection metadata. A
+rehydration request atomically projects the currently authorized caller
+capabilities, so a valid current policy containing both capabilities returns
+both
+governed-task:project and release:candidate in effective_scopes. No raw
+credential, bearer, token, or credential hash is stored.
+
+ACKED means the broker completed the server-side projection transaction and
+validated the returned public state. It is not an Owner Approval, release
+approval, deployment authorization, or release-worker identity.
+
+## Credential rehydration, expiry and revocation
+
+Credential material is generated server-side, sent only in the private Unix
+socket response header to the model API process, consumed for admission, and
+discarded. The public response and introspection never contain it.
+
+Each request reloads policy state. Missing, malformed, expired or revoked
+policy, caller mismatch, capability mismatch, invalid projection state,
+credential generation failure, or broker outage fails closed. Projection rows
+are short-lived metadata and are rehydrated after process restart; the
+rehydration state is GENERATED or RECOVERED.
+
+The exact caller uses governed-task:project for createGovernedTask admission.
+Other callers keep their existing branch:create path. The existing
+agent-task:control, branch:create and file:write static behavior remains
+available and is not expanded by this repair.
+
+## Bridge execution projection
+
+A governed task created through the existing Owner broker -> Bridge path
+receives metadata.execution with schema aios.online-agent.execution.v2 and an
+execution_projection record. A source_capture placeholder with write
+capabilities is intentionally not claimable. The existing deterministic plan
+registry and execution-rebind CAS path must produce the deterministic plan
+before a worker can claim it.
+
+The legitimate execution chain is:
+
+QUEUED -> PROJECTED -> deterministic-plan/rebind CAS -> CLAIMED
+-> heartbeat -> Writer Lease -> CAS branch/file writes -> tests
+-> official verifier -> immutable runtime evidence.
+
+Never write metadata.execution, task events, plan records, ACKs, outbox rows or
+broker database rows by hand. Never bypass the Bridge with SSH/root or a
+release-worker credential.
+
+## Restart recovery and failure states
+
+After broker or model API restart, repeat the read-only capability check and
+make one normal admission request. The broker must regenerate a short-lived
+credential from the durable policy and report RECOVERED without manual token
+operations.
+
+Useful fail-closed states include:
+
+- PROJECTION_BROKER_UNAVAILABLE
+- POLICY_FILE_INVALID
+- POLICY_EXPIRED
+- OWNER_GRANT_REVOKED
+- CALLER_MISMATCH
+- SCOPE_MISMATCH
+- CAPABILITY_NOT_AUTHORIZED
+- PROJECTION_STATE_INVALID
+- CREDENTIAL_REHYDRATION_MISSING
+- TASK_EXECUTION_PROJECTION_MISSING
+- TASK_PERSISTED_BINDING_CONFLICT
+- EXECUTION_REBIND_CAS_MISMATCH
+
+A rejected state is not repaired by editing SQLite, projection_outbox,
+static token registry, task metadata or task events.
+
+## Whoami and effective-scope diagnosis
+
+Use the read-only model API with the caller's existing credential:
+
+GET /api/caller-capabilities
+
+The response is safe to display and contains:
+
+- caller_identity
+- admitted
+- effective_scopes
+- projection_state
+- credential_state
+- rehydration_state
+- projection_error
+- secret_exposed=false
+
+For the authorized current policy, effective_scopes must contain:
+
+- agent-task:control
+- branch:create
+- file:write
+- governed-task:project
+- release:candidate
+
+No credential, token, bearer, password or secret value may appear in the
+response, logs, diagnostics, Git diff or Task metadata.
+
+For broker-level diagnosis use the read-only /v1/capabilities endpoint through
+the authorized Unix peer. It must identify the exact account and grant and
+show both durable capabilities; it must not be used to create manual ACKs.
+
+## Release:candidate troubleshooting
+
+For createReleaseCandidate, the caller must pass only source_commit and
+version to the model API. The durable policy constraint requires an exact
+40-hex source commit and version beginning with V2R2C. The model API first
+rehydrates release:candidate and then invokes the existing release service.
+
+If release admission fails, check caller-capabilities, policy validity,
+revocation state, projection_state, credential_state and rehydration_state.
+Do not add release:candidate to static tokens and do not use
+online-release-builder-cn-network-mkt-20260819.
+
+Creating and reading a Release Candidate is the end of this repair. Owner
+Approval, Deployment, Host Seed, Host Activation, Projector, continuation
+Task, Tag and Baseline actions are outside this scope.
