-# Caller admission projection and rehydration
-
-This runbook covers the exact durable Owner policy and the exact API caller:
-
-- caller: \`chatgpt-governed-implementer-singlehost\`
-- scope: \`release:candidate\`
-- policy source: \`/etc/aios-gitops/owner-durable-authorization.json\`
-- revocation source: \`/etc/aios-gitops/owner-durable-authorization-revocations.json\`
-
-## Admission source
-
-The model API first authenticates the existing caller token from the static
-registry. For this exact caller and exact release scope, static authentication
-is not sufficient. The model API calls the existing Unix-socket Owner broker.
-The broker reloads and validates the durable policy on every projection request,
-including account, capability, optional expiry, and revocation.
-
-Other callers retain their existing static-scope behavior. The target caller
-does not receive a permanent \`release:candidate\` entry in the static registry,
-and it is never treated as a release-worker account.
-
-## Projection lifecycle and ACK semantics
-
-The broker records only non-secret projection metadata in its existing durable
-state database. The state sequence is:
-
-\`PENDING\` -> \`ACKED\`
-
-The ACK is produced by the broker's server-side projection consumer after the
-exact policy and request binding have passed validation. The public response
-contains projection state, effective scope, policy digest, expiry and
-rehydration state. The short-lived credential material is returned only in a
-private Unix-socket response header to the model API process. It is not written
-to the response body, logs, diagnostics, Git, task metadata or terminal output.
-
-## Credential rehydration, expiry and revocation
-
-The credential projection is generated in memory for a short TTL and is
-discarded after the model API admission check. The durable row stores no raw
-credential and no bearer token. After a broker or model API restart, the next
-admission request creates a new short-lived credential from the durable
-projection metadata; this is reported as \`RECOVERED\`.
-
-Every request reloads the policy. Missing, malformed, expired or revoked policy
-fails closed. A caller mismatch, scope mismatch, invalid projection state,
-broker outage, missing credential header or unexpected secret field also fails
-closed. No static scope fallback is allowed for the target caller.
-
-## Diagnosis
-
-Use the read-only 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\`
-- \`secret_exposed=false\`
-
-It never contains a bearer, token, credential value or credential hash.
-
-For a release candidate request, the model API also binds the exact
-\`source_commit\` and \`version\` to the durable policy before invoking the
-trusted release service. The caller cannot supply release evidence fields.
-
-## Failure states and troubleshooting
-
-- \`PROJECTION_BROKER_UNAVAILABLE\`: verify the broker unit, socket path and
-  the model API supplementary groups; do not add a static scope.
-- \`OWNER_GRANT_REVOKED\` or \`POLICY_EXPIRED\`: restore a valid Owner policy
-  through governed policy management; do not edit broker state.
-- \`CALLER_MISMATCH\` or \`SCOPE_MISMATCH\`: verify the authenticated account and
-  requested exact scope.
-- \`PROJECTION_STATE_INVALID\`: inspect the durable projection through the
-  broker's read-only diagnostics and fail closed until it is reconciled.
-- \`CREDENTIAL_REHYDRATION_MISSING\`: restart only the related control-plane
-  service after capturing pre-state and then repeat the read-only diagnosis.
-- \`trusted candidate builder is not configured\`: Gate A admission is working,
-  but the separate existing TrustedCandidateBuilder runtime must be restored
-  before Gate B can create a candidate.
-
-No Owner Approval, Deployment, Host Seed, Host Activation, Projector,
-continuation task, Tag or Baseline action is part of this path.

+# Online Agent Automatic Claim Infrastructure
+
+## Status and fixed boundary
+
+This candidate targets `p0-claim-online-agent-auto-execution-20260817` on governed Job
+`job-2031a9e5682a4238f98e3ac7aee8a593`, base
+`a642b045775b9154a00ae78543037fbef4fb447b`, target branch
+`agent/p0-claim-online-agent-auto-execution-20260817`, generation 1.
+
+It does not authorize protected-main, Production, tag, baseline, raw Git, Task DB, or
+credential mutations.
+
+## Considered approaches
+
+1. Require every caller to write `metadata.execution`. This is simple but preserves the
+   current operational gap: a valid governed Job can still project an unexecutable Online
+   Task.
+2. Let workers infer repository and WriterLease coordinates from natural-language Task
+   fields. This removes the skip but violates fail-closed lineage and can bind the wrong Job,
+   branch, base, or generation.
+3. Use a canonical server-side projector plus a task-agnostic worker resolver. This is the
+   selected approach. The governed binding remains the only authority for repository, Job,
+   branch, base, expected head, generation, and idempotency. Producers can persist the
+   projected envelope when creating the Online Task. A worker may recover an omitted envelope
+   only from the same canonical projector and durable binding; it never guesses coordinates.
+
+## Components
+
+### Canonical execution contract
+
+`aios_online_agent_execution.py` owns schema `aios.online-agent.execution.v2`. It validates
+the complete governed lineage and supports two explicit actions:
+
+- `deterministic`: a hash-bound change set, verification commands, and governed commit;
+- `source_capture`: a read-only first attempt that returns `NEEDS_REWORK_SOURCE_CAPTURE` and
+  cannot acquire WriterLease or mutate Git.
+
+Wrong task, Job, repository, base, expected head, branch, generation, capability scope, or
+governance policy fails closed with a canonical diagnostic.
+
+### Governed Job to Online Task projection
+
+`GovernedTaskBootstrap` exposes an exact durable binding lookup and builds Online Task
+projection data through the canonical contract. When the Bridge is configured with the
+official Agent Task control credential reference, governed Job creation submits that complete
+projection through the official Task HTTP API. The Bridge also exposes a loopback envelope
+projection operation used for recovery. The persisted projection includes the versioned
+envelope rather than relying on manual metadata edits.
+
+Projection delivery is a durable outbox, not a best-effort tail call. The outbox record is
+written before HTTP delivery and a Bridge reconciler retries it after transient API failure or
+process restart. A response is accepted only when its complete execution envelope equals the
+submitted projection. Requests that explicitly require projection are rejected before governed
+bootstrap when the projection principal is unavailable.
+
+Loopback is not treated as an identity boundary. Every POST route requires an exact
+runtime-principal bearer credential supplied by systemd credential projection; unauthenticated
+local callers are denied before request dispatch. The control-plane credential used to create
+Online Tasks remains a separate Bridge-only reference and is never projected into the worker.
+
+For legacy Online Tasks with an omitted envelope, the generic worker asks the same Bridge
+operation for a read-only `source_capture` envelope. Projection succeeds only when the exact
+durable binding exists. An omitted envelope is therefore recoverable; an invalid envelope is
+never replaced or weakened.
+
+Persisted envelopes are also reprojected through the Bridge before claim and compared by exact
+digest and Job lineage. A self-consistent client-generated envelope is therefore not authority.
+
+### Dynamic worker and trusted consumer
+
+The repository gains a deployable generic worker and systemd unit definitions as governed
+source files. The worker validates or
+resolves an envelope before claim, revalidates after atomic claim, starts heartbeat, and then
+executes the selected action. The trusted engineering consumer uses this same task-agnostic
+entrypoint. No compiled worker contains a Task ID, base OID, branch, generation, or plan path.
+
+Skip observability distinguishes:
+
+- `TASK_SKIPPED_PROJECTION_MISSING`;
+- `TASK_SKIPPED_ENVELOPE_INVALID`;
+- `TASK_SKIPPED_CAPABILITY_MISMATCH`;
+- `TASK_SKIPPED_POLICY_DENY`;
+- `TASK_POLL_FAILED` / worker unavailable.
+
+## State flow
+
+```text
+Governed Job BOUND
+  -> canonical durable binding
+  -> Online Task projection with execution.v2
+  -> capability-filtered poll
+  -> envelope and lineage validation
+  -> atomic claim
+  -> initial heartbeat/start
+  -> refetch Task and re-resolve envelope
+  -> compare execution digest and Job
+  -> source capture OR deterministic governed execution
+  -> result construction
+  -> result submission
+  -> external server-side verification gate
+```
+
+Legacy omission uses `binding -> source_capture projection` between poll and validation. It
+does not write Task metadata and does not convert a malformed envelope into a valid one.
+
+## Recovery and safety
+
+- Projection is deterministic and digest-bound.
+- Governed Task creation is serialized by a cross-process, Task-ID-digest lock. Durable paths
+  use collision-resistant exact Task keys while retaining read compatibility with verified
+  legacy bindings.
+- A new Task cannot adopt an existing branch from caller-selected generation data. It must name
+  an exact durable parent Task/Job whose single ACTIVE lease owns the branch head; generation is
+  then derived from that lease.
+- Claim is attempted only after validation; claimed payload drift is denied.
+- Source capture has no WriterLease or commit path.
+- Deterministic execution retains detached worktree, exact WriterLease, governed commit,
+  durable current-head CAS, and receipt convergence.
+- Local deterministic recovery is keyed by Task and execution digest; live acceptance must
+  independently reconverge Job, lease, receipt, and branch OIDs before verification.
+- An ambiguous commit transport or server outcome becomes `RECONCILIATION_REQUIRED`; the
+  worker does not submit a canonical failure until exact Job receipt and head evidence is
+  observed.
+- A completed read-only `source_capture` state is ignored when a later attempt has a changed
+  digest and no governed state exists; all other digest drift is denied.
+- Protected refs are never worker targets.
+
+## Acceptance
+
+The implementation must pass the named projection, schema, claimability, dynamic-binding,
+wrong-lineage, capability, P0-A, and P0-B tests. Runtime acceptance additionally requires a
+real Online Task to be claimed and heartbeated without per-task worker or systemd plan
+injection, plus governed receipt/OID/CAS convergence for this implementation Task.
+Unit tests and deployable unit definitions do not by themselves satisfy runtime acceptance.

+# P0-CLAIM Scheme A follow-up
+
+This follow-up continues the existing candidate `71523aef6e48b1e2fa516c456ca189b7a039104b`.
+It does not create a replacement Task, Job, branch or generation.
+
+## Retry extension
+
+A versioned Owner-controlled loopback API provides
+`POST /v1/tasks/{task_id}/retry-extension`.
+
+The request binds FAILED status, revision, exhausted attempt/max_attempts, next max attempts,
+previous verification SHA256, Owner authorization ID and idempotency key. The service performs one
+SQLite `BEGIN IMMEDIATE` transaction containing the CAS update, durable retry-extension record and
+Task event. Each authorization extends the boundary by exactly one attempt.
+
+## Same-Job continuation
+
+The durable GovernedTask binding remains the lineage anchor. After the first CREATE_NEW commit,
+`execution_binding()` may normalize that SAME Job to `CONTINUE_EXISTING` only when exactly one
+ACTIVE WriterLease for the Job owns the current authority branch head, generation and lineage
+anchor. The lineage `base_oid` stays unchanged; only `expected_branch_oid` becomes the current head.
+
+GovernedTask creation is also serialized by a branch-digest lock, preventing sibling continuation
+tasks from racing generation admission.
+
+## Projection and recovery
+
+Natural-language source signals are normalized server-side to at most 16 unique 512-byte values.
+Malformed persisted envelopes still fail closed.
+
+Fresh commits and recovery require a COMPLETED Job, `remote_verified=true`, exact
+authority/API/remote receipt OIDs, and exactly one ACTIVE WriterLease whose durable current head
+matches the commit. Delayed local ref visibility becomes `RECONCILIATION_REQUIRED`, not a terminal
+canonical failure.
+
+## Credential isolation
+
+The credentialed Coordinator performs only Task/Bridge coordination and governed commit. All
+deterministic repository modification and test commands run in
+`aios-online-agent-isolated-executor` under a separate system user with:
+
+- no Agent/Owner credential projection;
+- no gitops supplementary group;
+- `PrivateNetwork=true`;
+- `RestrictAddressFamilies=AF_UNIX AF_INET`, with `IPAddressDeny=any` and
+  `IPAddressAllow=localhost`, so regression tests may use an isolated loopback
+  HTTP server without gaining host or external network reachability;
+- `InaccessiblePaths=/run/credentials`.
+
+The executor receives a hash-bound source archive and deterministic change set through a filesystem
+exchange and returns only changed file bytes/hashes plus command evidence. The Coordinator validates
+that response before materializing exact allowed files and calling the governed Bridge.
+
+Codex/Hermes mutation adapters remain disabled until a separately audited uncredentialed planner
+backend exists. Under the current operating model, implementation code is authored before Online
+Agent execution and is carried as a deterministic plan.
