+# AIOS Autonomous Control Plane — Admission + Invariant + Repair
+
+## Why this exists
+
+Recent Agent registration, Task claim, release-worker, credential and retry failures shared one
+failure mode:
+
+> The control plane accepted an intent before the runtime had proved it could execute the intent.
+
+This design does not add another fleet of daemons. It adds one shared library contract that Task API,
+workers and governed host recovery consume.
+
+## Three layers
+
+```text
+Intent
+  ↓
+Runtime Admission
+  ↓
+System Invariants
+  ↓
+Repair Policy
+  ↓
+Execution
+```
+
+### Runtime Admission
+
+Admission occurs before Task claim.
+
+A capability such as `release:candidate` is not considered executable merely because its name
+matches. The capability contract also binds:
+
+- supported contract version;
+- allowed permission;
+- forbidden operations;
+- runtime dependencies;
+- health requirements.
+
+For `release:candidate`:
+
+```text
+permission:
+  prepare_release
+
+forbidden:
+  production_deploy
+  submit_owner_approval
+  tag_publish
+  baseline_registry_finalize
+  runtime_switch
+
+dependencies:
+  credential_projection
+  trusted_builder
+
+health:
+  authenticated_probe
+  release_api_health
+  worker_liveness
+```
+
+Only a fully passing decision reaches:
+
+```text
+EXECUTION_READY
+```
+
+A failed decision remains:
+
+```text
+EXECUTION_READY_FAILED
+```
+
+and the worker does not call `/claim`.
+
+Therefore an infrastructure defect discovered by admission does not consume a business attempt.
+
+### System Invariants
+
+The same admission checks are exposed as a machine-readable invariant snapshot.
+
+Examples:
+
+```text
+capability_contract_registry
+task_capabilities_registered
+worker_capabilities_registered
+capability_match
+forbidden_operations_absent
+credential_projection
+trusted_builder
+authenticated_probe
+release_api_health
+worker_liveness
+```
+
+A runtime can expose:
+
+```text
+HEALTHY
+DEGRADED
+```
+
+without relying on a human reconstructing state from logs.
+
+### Repair Policy
+
+Failure classification maps to bounded recovery:
+
+```text
+DEPENDENCY_UNAVAILABLE       → level 0 / auto local
+RESOURCE_UNAVAILABLE         → level 0 / auto local
+WORKER_CRASH                 → level 0 / auto local
+LEASE_LOST                   → level 0 / auto local
+
+CAPABILITY_CONTRACT_ERROR    → level 1 / same-lineage repair task
+CREDENTIAL_PROJECTION_ERROR  → level 1 / same-lineage repair task
+UNKNOWN                      → level 1 / diagnostic repair task
+
+POLICY_DENIED                → level 2 / Owner authorization
+BUSINESS_PERMANENT           → level 3 / terminal/manual decision
+```
+
+Only business-permanent failure consumes the business retry budget in this first contract.
+
+The current Task API does not yet have a first-class `EXECUTION_READY_FAILED` durable state. Until it
+does, the Release Worker enforces the most important invariant by refusing to claim a Task whose
+admission fails.
+
+## Capability Contract Registry
+
+`aios_capability_contract.py` remains backward-compatible with existing aliases but now validates
+every alias target against a versioned semantic contract registry.
+
+Unknown capabilities and wildcard capabilities remain fail-closed.
+
+Agent registration and Task creation should next be changed to call `registered_capability()` so a
+capability cannot be accepted at registration and rejected only later by the matcher.
+
+## Credential rule
+
+Admission probes credential usability, not merely credential existence.
+
+For release candidate creation the authenticated probe intentionally sends an invalid empty
+`/createReleaseCandidate` request.
+
+Expected:
+
+```text
+HTTP 400
+```
+
+This proves:
+
+```text
+credential readable
+→ authentication succeeded
+→ scope accepted
+→ request validation rejected empty business input
+```
+
+A permission failure/401/403/5xx is `EXECUTION_READY_FAILED`.
+
+## Lineage
+
+Repair actions are descriptive, not permission grants. Any repair Task must retain the existing
+root/parent/attempt/authority chain and use governed same-lineage recovery.
+
+No repair action may silently create a replacement business Task.
+
+## Authority separation
+
+Capability answers:
+
+```text
+can this runtime perform the operation?
+```
+
+Authority answers:
+
+```text
+is this operation currently authorized?
+```
+
+`release:candidate` never implies Owner approval, deployment, tag publication, baseline finalization
+or runtime switch.
+
+## Deployment sequence
+
+Phase 1 (this candidate):
+
+- Capability Contract Registry;
+- shared Autonomous Control Plane library;
+- Release Worker pre-claim admission;
+- failure classification + repair evidence.
+
+Phase 2:
+
+- Task API uses the same library before returning Tasks from poll and again during claim CAS;
+- Task schema gains durable `ADMITTED/EXECUTION_READY/EXECUTION_READY_FAILED` evidence without
+  counting pre-side-effect infrastructure failures against business attempts.
+
+Phase 3:
+
+- Agent registration validates against the same Capability Contract Registry;
+- external connector writes only durable Intent/Command Inbox records and leaves execution to the
+  local control plane.
+
+This sequencing avoids a second controller stack while converging every decision onto one contract.
