+"""Canonical Task projection intent and same-identity recovery primitives.
+
+This module is intentionally Task-Plane-owned.  It does not open a network
+listener and it does not authenticate callers; existing control-plane services
+must enforce their normal service-side ``agent-task:control`` boundary before
+calling it.
+
+The recovery primitive has one purpose: converge a durable, complete
+ProjectionIntent to exactly one canonical Task row.  It never fabricates task
+semantics from a Bridge binding and it never generates a replacement task id.

-# R4.2 P0-A TaskPlane Scope Isolation Design
-
-Status: approved candidate design. This document is not evidence of a protected-main merge or production deployment.
-
-## Boundary
-
-- Task: `r42-p0a-taskplane-scope-isolation-20260816`
-- Governed Job: `job-3fd743b51971c6007923699c1233f84c`
-- Repository: `aios/aios`
-- Base: `0eb6e1a864edfdaeef37b438991707a110e21558`
-- Target branch: `agent/r42-p0a-taskplane-scope-isolation-20260816`
-- Generation: `1`
-
-The implementation reuses this exact boundary. It does not create a replacement Task, Job, branch, generation, or idempotency key.
-
-## Model and invariants
-
-`TaskPlan` gains first-class `scope_type`, `tenant_id`, `user_id`, `project_id`, `conversation_id`, and `run_id` fields. The fields participate in accepted-key validation, parsing, serialization, persistence, and authorization.
-
-Historical rows without scope data normalize to `scope_type=legacy`; no tenant is inferred. Tenant-scoped tasks require a non-empty `tenant_id`. System/global resources use an explicit `scope_type=system` invariant and do not receive a fabricated tenant. A task may add user, project, conversation, and run ownership within its tenant.
-
-## Trusted ActorContext
-
-TaskPlane defines a small immutable `TaskActorContext` used only for authorization. The HTTP authenticator returns an identity. `PolicyEngine` resolves that identity through server-owned policy configuration into the effective context and capabilities. Request fields such as `tenant_id`, `user_id`, `group_id`, and `role` are declarations only and never expand authority.
-
-Public create, list, and get paths always use the resolved context. Internal compatibility calls may omit a context and retain explicit legacy behavior, but the HTTP adapter never uses that path.
-
-## Persistence
-
-SQLite remains the current runtime. `_create_schema()` performs an idempotent forward migration that adds the six scope columns and indexes, then backfills only missing `scope_type` values to `legacy`.
-
-New writes persist scope in both the canonical `task_json` representation and first-class columns. Reads accept historical JSON without scope, using legacy columns, but reject a new-row mismatch between JSON and columns. SQL list/get predicates are parameterized and applied before row hydration.
-
-PostgreSQL remains a separate migration target and is not claimed by this change.
-
-## Authorization flow
-
-1. HTTP bearer authentication yields an identity.
-2. `PolicyEngine` verifies capability and resolves the identity to `TaskActorContext`.
-3. Create binds the requested scope to the trusted context and rejects mismatches.
-4. List/get pass the trusted context to `TaskPlaneStore`.
-5. Store applies tenant and ownership predicates in SQL; privileged capabilities may explicitly cross scope.
-
-Tenant actors cannot read legacy tasks, another tenant, or mismatched owned resources. Legacy actors can only read legacy tasks. System actors require explicit privileged capability for cross-scope access.
-
-## Failure behavior
-
-Missing tenant scope, forged scope, unknown scope types, JSON/column divergence, and unauthorized list/get operations fail closed with canonical TaskPlane errors. Public get does not reveal whether an out-of-scope task exists.
-
-## Verification
-
-Tests exercise real model round trips, SQLite migration/restart, Service/Policy/Store wiring, tenant A versus tenant B list/get denial, ownership filtering, forged create payload rejection, legacy isolation, privileged access, and SQL parameterization. Existing TaskPlane API, RBAC, recovery/security, and security-contract suites remain mandatory.
-
-The candidate is complete only after real `TASK_CLAIMED`, `TASK_HEARTBEAT`, exact WriterLease, governed commit, OID convergence, result submission, and `TASK_VERIFIED`. Protected main and production remain unchanged.

-# R4.2 P0-C Trace / Tool-MCP / Credential Governance
-
-## Status boundary
-
-This change is a candidate implementation on the governed P0-C branch. It does
-not promote protected `main`, deploy Production, or assert that all R4.2 target
-architecture is complete.
-
-## Scope model
-
-Governance resources use an explicit `scope_type`:
-
-- `tenant` requires `tenant_id` and may narrow to user, project,
-  conversation, and run;
-- `system` and `global` prohibit tenant ownership fields;
-- `legacy` preserves unscoped historical records without inventing ownership.
-
-System and global tools therefore never receive a synthetic tenant merely to
-satisfy a tenant-oriented schema.
-
-## Trace lineage
-
-`TaskPlan` and `MessageEnvelope` scope is bound to a `TraceContext`. The trace
-records `trace_id`, `span_id`, parent span, correlation, causation, task,
-message, and the canonical P0-A scope. Child spans must keep the parent's trace,
-task, and scope. Privileged visibility does not permit cross-scope trace
-splicing.
-
-`MessageEnvelope.correlation_id` is persisted and identity-bound. Existing
-handoff databases are upgraded in place with an idempotent column migration;
-legacy rows retain their prior event IDs because a null correlation field is
-not added to the historical identity material.
-
-Observability keeps its legacy presentation fields, but new governed records
-also carry immutable trace and scope fields. Scoped records require a trusted
-server actor for queries. A repeated execution ID is an idempotent replay only
-when the complete record matches; conflicting overwrites are denied.
-
-## Tool and MCP governance
-
-`ToolDescriptor` binds a tool or MCP server to:
-
-- an explicit resource scope;
-- required actor capabilities;
-- an optional credential reference.
-
-Invocation authorization requires exact propagation of the trace scope and a
-capability superset. Unknown tools, cross-tenant calls, scope substitution, and
-non-privileged access to system/global resources fail closed. Every successful
-registration and invocation appends hash-chained audit evidence.
-
-## Credential governance
-
-Credentials are represented only by references whose schemes are
-`systemd-credential`, `vault`, or `secret-manager`. Raw bearer tokens, passwords,
-and arbitrary values are rejected. Grants are bound to scope, operation, task,
-tool, and expiry. Public/audit records contain a reference hash where disclosure
-is unnecessary; secret material is never persisted by this module.
-
-The existing runtime credential broker remains backward compatible for system
-leases, adds explicit tenant/system/global invariants, and rejects providers
-that attempt to return raw token/secret/password environment values instead of
-file/reference indirection.
-
-## Durable evidence
-
-The SQLite governance store is restart-safe and idempotently initializes four
-tables: governed tools, trace spans, credential grants, and audit evidence.
-Audit entries form a SHA-256 chain. Acceptance requires the chain to verify and
-contain the required actions; missing evidence is not treated as success.
-
-## Acceptance tests
-
-The candidate must pass:
-
-- `TRACE_LINEAGE_CONTINUITY`;
-- `TRACE_SCOPE_MISMATCH_DENY`;
-- `TOOL_MCP_AUTHZ_DENY`;
-- `TOOL_SCOPE_PROPAGATION`;
-- `CREDENTIAL_SCOPE_DENY`;
-- `CREDENTIAL_SECRET_EXPOSURE_DENY`;
-- `AUDIT_EVIDENCE_COMPLETENESS`;
-- P0-A scope and P0-B handoff regression suites;
-- Python compilation, `git diff --check`, and a diff-scoped secret scan.
-
-The repository-wide baseline currently has seven unrelated failures in the
-isolated host environment (five stale continuation-contract fixtures and two
-host-permission fixtures). The same seven failures reproduce at the untouched
-`a642b045775b9154a00ae78543037fbef4fb447b` base; they are not suppressed or
-modified by P0-C.

-# R4.2 P1 — Durable Online Agent Execution
-
-Status: candidate implementation. This document does not imply protected-main promotion or Production deployment.
-
-## State model
-
-The generic worker uses two local durable layers:
-
-1. `tasks/<task_id>.json`: atomic fast-state cache for compatibility and quick restart.
-2. `checkpoints.sqlite3`: append-only attempt/phase journal with `synchronous=FULL`.
-
-Checkpoint identity is bound to:
-
-- task_id
-- attempt
-- execution_digest
-- job_id
-- repository
-- base_oid
-- expected_branch_oid
-- target_branch
-- generation
-
-A checkpoint from another repository/branch/generation is never reused.
-
-Phases are monotonic within an attempt:
-
-`claimed → workspace_prepared → verification_passed → source_capture_done|commit_done → result_pending → result_submitted`
-
-`reconciliation_required` is an explicit recovery phase.
-
-## Attempt-aware result idempotency
-
-Result submission idempotency keys include the official Task attempt and the execution digest. The same
-attempt reuses the same key after a timeout/restart; a later official attempt cannot collide with an
-earlier result.
-
-Before submitting a result the worker durably writes `result_pending`, including the result hash and
-idempotency key. After a successful or exact-idempotency-reconciled API response it writes
-`result_submitted`.
-
-A 409 is accepted only if the Task API already contains the exact same result body and the Task is
-VERIFYING/SUCCEEDED. A conflicting result remains a hard failure.
-
-## Resume rules
-
-- `source_capture_done` and `result_pending` may be reused across later official attempts only when the
-  execution/scope binding is identical. This avoids repeating read-only source capture.
-- A deterministic task that crashed before governed commit replays from a new clean detached worktree.
-  This is safe because there is no external side effect yet.
-- `commit_done` is never recommitted. Recovery requires exact Job receipt OID convergence plus exactly
-  one ACTIVE WriterLease whose `current_head_oid` equals the governed commit.
-- delayed Git visibility remains `RECONCILIATION_REQUIRED`, preserving an explicit recovery entry.
-
-## Crash cleanup
-
-On worker startup, stale `task-*` workspaces under the configured workspace root are removed before
-polling begins. The path boundary is verified before deletion.
-
-## Contracts
-
-P1 gates include:
-
-- CHECKPOINT_DURABLE_WRITE
-- RESUME_FROM_CHECKPOINT
-- RETRY_IDEMPOTENT_NO_DUPLICATE_SIDE_EFFECT
-- CRASH_RECOVERY_CONVERGENCE
-- WORKER_RESTART_RESUME
-- CHECKPOINT_SCOPE_ISOLATION
-- RESULT_SUBMISSION_REPLAY_SAFE
-- WORKSPACE_CLEANUP_RECOVERY
-- LEASE_RENEWAL_RECOVERY
-
-WriterLease and governed Job authority remain in the existing Bridge/GitOps durable stores; the worker
-checkpoint DB is not a competing authority for Git state.

-remains authoritative for ownership. Probe-before-reassignment remains mandatory after an expired
-lease. P1 checkpoint/result replay remains authoritative after worker restart.

-`FleetScheduler` adds durable worker capacity slots, weighted scope fairness, starvation aging,

-# R4.2 P2 Compact Interface Map Runtime
-
-## Purpose
-
-The persistent Online Agent already supports the canonical read-only `source_capture` action, but
-its `SourceCaptureExecutor` always returns an `aios.engineering.source-snapshot.v2` tar.gz+base64
-payload. That is correct for implementation source transfer, but too large for control-plane
-consumers that only need a bounded implementation map.
-
-P2 adds a new **adapter**, not a new execution action:
-
-```text
-action=source_capture
-adapter=compact_interface_map
-```
-
-This preserves the existing execution-v2 schema and Bridge policy:
-
-- read-only repository;
-- no change set;
-- no verification commands;
-- `writer_lease=false`;
-- no branch or commit;
-- existing capability and execution-digest validation.
-
-## Compact map contract
-
-`aios_online_agent_compact_map.py` scans only approved repository roots and source suffixes. It
-returns:
-
-- at most 40 relevant modules;
-- at most 80 selected Python symbols in total;
-- at most 40 test symbols;
-- at most 25 excerpts;
-- at most 1200 characters per excerpt;
-- SQL table names;
-- systemd unit names;
-- current invariants, failure windows and reuse points;
-- P2 fleet contract-to-surface mappings.
-
-The result is hard-bounded to 120 KiB and contains no source archive or `payload_b64`.
-
-Source excerpts apply a conservative sensitive-pattern redaction before result construction.
-
-## P2 contracts
-
-The map supplies evidence surfaces for:
-
-- `FLEET_AGENT_REGISTRATION`
-- `FLEET_CAPACITY_SCHEDULING`
-- `FLEET_FAIRNESS`
-- `FLEET_FAULT_ISOLATION`
-- `FLEET_WORKER_REASSIGNMENT`
-- `FLEET_SCOPE_ISOLATION`
-- `FLEET_IDEMPOTENT_DISPATCH`
-- `FLEET_FAILURE_RECOVERY`
-
-Missing first-class scheduling/fleet primitives are reported as gaps rather than invented.
-
-## Result
-
-When the adapter is selected, the worker returns:
-
-```text
-status=SUCCEEDED
-classification=P2_INTERFACE_MAP_CAPTURED
-execution_mode=compact_interface_map
-writer_lease=NONE
-```
-
-The existing `source_capture_done` / P1 checkpoint/retry path is reused, so the compact analysis
-inherits attempt-aware result idempotency and restart-safe result submission.
-
-## Governance
-
-This capability is runtime infrastructure only. The implementation candidate may use a governed
-branch/WriterLease for its own code change, but any task executed through `compact_interface_map`
-is read-only and must not create a WriterLease, branch, commit, protected-ref write, or Production
-side effect.

+# Action Contract Regression Remediation — 2026-08-25
+
+## Scope
+
+Governed task: `fix-action-contracts-20260825-1407`
+Base: `3244f0f17f8845592ac94d585f5ebd65693c9f29`
+Target branch: `agent/fix-action-contracts-20260825-1407`
+
+## Verified regressions
+
+1. `getReleaseConsistency` and `runReleaseAcceptance` fail before evaluation with:
+   `Gitea API URL must be HTTP(S)`.
+   V2R2C1 release evidence at `a8b906d1bc24088c19647e98de6a679268f6d0a2`
+   proves Gitea API readback passed for target `998d30304787e31e5ae607c0bd86b5edb2b0e5ad`.
+   Therefore current staging/contract overlay configuration has regressed.
+
+2. `getReleaseSaga` fails with:
+   `Permission denied: '/var/lib/aios-gitops/silent-release'`.
+   Runtime service identity must have read/traverse access to the durable release state root.
+   Fix ownership/group/ACL at deployment time; do not broaden to world-writable permissions.
+
+3. `getTagPublicationStatus` rejects the authoritative approved version `V2R2C1`
+   as `invalid release version`, while `getGovernedWriteCapabilities` returns the same
+   version as the approved release scope. The two Action contracts are internally inconsistent.
+   Release-version validation must accept the canonical AIOS `^V[0-9]+R[0-9]+C[0-9]+$`
+   namespace (or, preferably, use one shared validator for all release Actions).
+
+4. `commitFilesGoverned` is unusable from the published Action schema.
+   Runtime capability metadata declares required fields:
+   `task_id, repository, expected_branch_oid, target_branch, generation, idempotency_key, files, message`,
+   but the exposed tool contract has no `files` input. Regenerate/publish the Action schema from
+   the same operation contract source and add a contract-parity test.
+
+5. `reconcileGitOpsJob` returned `DURABLE_BINDING_INVALID` for a completed governed
+   single-file job that was otherwise read back as `COMPLETED`.
+   Reconciliation of a valid terminal job should be idempotent/read-only and must not require
+   a stale or absent active lease. Add a regression case for terminal completed jobs.
+
+6. `getDiff` returns `ResponseTooLargeError` / `GIT_OUTPUT_LIMIT_EXCEEDED` for large diffs.
+   Add server-side bounded output: path/stat summary plus truncation metadata, or pagination.
+   The Action must never fail merely because a valid repository diff is large.
+
+## Required implementation changes
+
+- Centralize release-version parsing and reuse it in tag status, candidate, consistency, and acceptance.
+- Validate/normalize Gitea API URL at service startup and fail health checks with a configuration-specific diagnostic.
+- Ensure the deployment unit projects a valid HTTP(S) Gitea API base URL into the staging overlay.
+- Correct durable release-state directory ownership/ACL for the runtime service account.
+- Generate the external Action schema from the runtime operation contract; parity-test required fields.
+- Make terminal reconciliation idempotent and independent of expired active writer leases.
+- Bound diff output and return `truncated=true` with deterministic metadata rather than transport failure.
+
+## Acceptance gates
+
+All must pass on the same deployed overlay:
+
+- `getReleaseConsistency(V2R2C1, 998d303..., a8b906d..., approved_plan)` returns a structured result, not URL error.
+- `runReleaseAcceptance(...)` reaches policy evaluation, not URL error.
+- `getTagPublicationStatus("V2R2C1")` returns structured publication state.
+- `getReleaseSaga(nonexistent_candidate)` returns NOT_FOUND/empty-state semantics, never filesystem permission failure.
+- Published `commitFilesGoverned` schema exposes `files` and a two-file isolated branch commit succeeds.
+- Reconcile of a completed governed job is idempotent.
+- Large diff returns bounded/truncated data rather than transport exception.
+- Existing protected-ref controls remain unchanged: no direct main/tag/baseline/production write.
+
+## Proven stable reference
+
+V2R2C1 evidence closure (`a8b906d1bc24088c19647e98de6a679268f6d0a2`) records:
+- Gitea Git/API readback PASS
+- staging runtime PASS
+- restart recovery PASS
+- 59 mandatory tests passed / 0 failed
+
+This evidence should be used as the compatibility baseline when repairing the current
+`contract-overlay-v2` / `scheme-a-323b615b...` staging layer.

+# AIOS Action contract repair evidence — 2026-08-25
+
+## Disposition
+
+Final disposition: `NEEDS_REWORK`.
+
+The contract repair is deployed to staging and the focused acceptance checks are green. The task is not eligible for `SUCCEEDED`: `runReleaseAcceptance` returns structured policy output with `accepted=false` because the existing publication state for protected tag `V2R2C1` is `REMOTE_PUSH_PENDING`, and the repository-wide suite still has the two pre-existing signer/event-bus failures recorded below. The online Task API row is still `QUEUED`; it was not changed by direct database manipulation or an unauthorized synthetic claim/result.
+
+No production release, `main`, release tag, baseline registry, or production service was directly modified.
+
+## Scope and pre-change facts
+
+- Repository: `aios/aios`; governed branch: `agent/fix-action-contracts-20260825-1407`.
+- Initial task branch HEAD: `35eec9afe1432e8466d60040b2fb1049bb41242a`.
+- Stable reference: `V2R2C1`; source commit `998d30304787e31e5ae607c0bd86b5edb2b0e5ad`; evidence closure `a8b906d1bc24088c19647e98de6a679268f6d0a2`.
+- Pre-change refs: authority `main=3244f0f17f8845592ac94d585f5ebd65693c9f29`, tag `V2R2C1=07fc2746b688f5f243f29b39de39f32edc3dd9d2`; these remained unchanged.
+- Staging services run as `User=aiman`, `Group=gitops`. The actual staging Gitea API base is `https://g.cnnetmkt.top/git/api/v1`, supplied by systemd environment rather than business-code host constants.
+- Pre-change full test baseline: `707 passed, 2 skipped, 154 subtests passed, 2 failed`. The failures were the stale `/tmp/aios-agent-events-test` event-bus fixture and the real signer self-test.
+
+## Root causes and repairs
+
+1. Gitea URL validation occurred at release-operation time while the staging overlay's API environment was not consistently projected into all runtime paths. The canonical HTTP(S) validator is now called during model and Bridge startup; `getReleaseConsistency` and `runReleaseAcceptance` use the actual staging environment URL.
+
+2. `silent-release` was not consistently writable by the real service identity, and the credential helper parent directory blocked `aiman` traversal. The persisted staging systemd overlay creates the state directory as `aiman:gitops` mode `0750` and grants only `u:aiman:--x` on `/usr/local/libexec`; no world-writable mode was used. The staging bridge also has the minimum repository write path required by the governed AuthorityGitExecutor/CAS flow.
+
+3. Release version parsing was split across callers and rejected `V2R2C1`. A shared canonical parser now accepts `^V[0-9]+R[0-9]+C[0-9]+$` plus the existing bounded suffix form, and is used by capabilities, release candidate, consistency, acceptance, tag publication, and release/tag queries.
+
+4. The runtime operation contract required `files` but the published Action schema omitted it. `commitFilesGoverned` now has one contract source and published schema projection, with parity tests. A real governed two-file commit completed on isolated branch `agent/action-contract-integration-20260825-1407`; authority, Git remote, and Gitea API all read back OID `0345cd8c70967940bc8e9132dff7d6ea11efa304`.
+
+5. `reconcileGitOpsJob` reconstructed active lease state before checking terminal state. Terminal `COMPLETED`, `FAILED`, and `CANCELLED` jobs now short-circuit to idempotent read-back; active jobs retain strict lease validation. The two-file job reconciled as `COMPLETED` and a second reconcile returned the same receipt.
+
+6. `getDiff` returned unbounded patch data and could fail the transport. It now returns identities, changed paths, stats, total bytes, bounded patch output, patch limit, and `truncated`. The large smoke returned `total_size_bytes=350222`, `stdout_bytes=262144`, `patch_limit_bytes=262144`, `truncated=true`; no `ResponseTooLargeError` or `GIT_OUTPUT_LIMIT_EXCEEDED` escaped.
+
+During live integration, two additional staging-only contract defects were found and repaired: CREATE_NEW branch normalization/CAS recovery, and release executor projection of the configured staging baseline plus immutable runtime `versions/V2R2C1.json`. The latter removed the missing publication-workspace baseline/version errors without writing production state.
+
+## Source, test, and operational changes
+
+Source commits on the governed branch include the six contract repairs, focused regression tests, `versions/V2R2C1.json`, governed CREATE_NEW/reconcile recovery, and final runtime projection commits. The final source before this evidence commit is `2ec49005bde44f6981b14351500847d594e0276c`.
+
+The runbook update is in `runbooks/agent-fix-action-contracts-20260825.md`. This report is the required durable evidence artifact. Existing untracked `runtime/agent-observability/` and `runtime/task-center/` directories were preserved and were not staged.
+
+Tests run on the final source:
+
+```text
+PYTHONPATH=active-runtime/app python3 -m pytest -q tests/test_silent_release_execution_readiness.py tests/test_silent_release_controller.py tests/test_silent_release_hardening.py tests/test_silent_release_production_contract.py tests/test_chatgpt_actions_tag.py tests/test_gitea_tag_publication.py tests/test_authoritative_git_context.py
+264 passed, 28 subtests passed in 4.78s
+
+PYTHONPATH=active-runtime/app python3 -m pytest -q tests
+717 passed, 2 skipped, 154 subtests passed, 2 failed in 33.98s
+```
+
+The full-suite failures remain the known event-bus fixture failure and the real signer adapter self-test (`returncode=42`); no new mandatory-suite regression was observed. Focused contract/reconcile tests and the exact mandatory suite passed.
+
+## Staging deployment identity
+
+- Final deployed source OID at the last completed runtime smoke: `2ec49005bde44f6981b14351500847d594e0276c`.
+- Final deployed artifact: `/opt/aios/gitops-model-api/2ec49005bde44f6981b14351500847d594e0276c-action-contract-repair/runtime`.
+- Artifact SHA256: `f67aed6cc0cce1f08197485c3eea204d3ef4d3989f44dc98e8ea2691e5886cbf`.
+- Deployment state: `STAGING`; production-deployed flag: `false`.
+- A lexically highest staging-only systemd drop-in was installed for each affected service, followed by `daemon-reload` and restart. `systemctl is-active` returned `active` for both services, and `systemctl show` confirmed the final OID, artifact SHA, API URL, and baseline authority.
+
+## Runtime smoke evidence
+
+- Model health returned `status=ok`, `version=V2R2C1`, final commit/artifact identity, `deployment_state=STAGING`, and `production_deployed=false`.
+- Bridge/API readback was available; the bridge's `/health` path is not exposed by this runtime and returned `404`, while its governed endpoints were healthy.
+- `getReleaseConsistency("V2R2C1", ...)` returned structured `status=PASS`, with Gitea listing/peeled target and tag object matching the stable reference.
+- `runReleaseAcceptance(...)` entered policy evaluation and returned structured `accepted=false`; it did not fail URL validation. The independent pre-existing tag publication state is `REMOTE_PUSH_PENDING`, with the remote rejection explicitly reporting protected tag `V2R2C1`.
+- `getTagPublicationStatus("V2R2C1")` returned structured `REMOTE_PUSH_PENDING`, not `invalid release version`.
+- `getReleaseSaga` for a nonexistent candidate returned HTTP `404` with `status=NOT_FOUND`, `state=NOT_FOUND`, `execution_enabled=false`, and no filesystem permission error.
+- `commitFilesGoverned` published schema includes required `files`, with per-file `path` and `content_base64`.
+- Two-file governed commit: branch `agent/action-contract-integration-20260825-1407`, OID `0345cd8c70967940bc8e9132dff7d6ea11efa304` at authority/Git remote/API; protected-ref flags remained false.
+- Terminal reconcile: `COMPLETED` read-back was idempotent across two calls; focused tests cover `FAILED` and `CANCELLED` terminal semantics.
+- Small diff returned bounded non-truncated output; empty diff returned zero paths and zero bytes; large diff returned bounded/truncated output as recorded above.
+- Main, protected tag, baseline registry, and production OIDs were re-read after deployment and remained unchanged.
+
+## Restart persistence and remaining risk
+
+The final staging services were restarted after deployment and health/runtime identity were re-read. The post-restart `systemctl is-active` result was `active` for both services; model health again reported OID `2ec49005bde44f6981b14351500847d594e0276c`, artifact SHA `f67aed6cc0cce1f08197485c3eea204d3ef4d3989f44dc98e8ea2691e5886cbf`, staging mode, and `production_deployed=false`. Post-restart consistency remained `PASS`, acceptance remained structured `accepted=false` for the pre-existing protected-tag publication state, saga remained `NOT_FOUND` for the nonexistent candidate, and the large diff remained bounded/truncated. The task cannot be promoted to `SUCCEEDED` until the protected-tag publication state and the two known repository-wide failures are resolved through their respective governed owners. No automatic rollback was performed because the staging services stayed healthy, mandatory tests passed, Gitea readback passed, and protected-ref boundaries remained intact.
+
+Task disposition is `NEEDS_REWORK`, not `SUCCEEDED`: the staging contract repair is materially complete, but the deployed acceptance result is not all-green and the task row has not been legitimately claimed/verified by the online task worker.

+# Agent Execution Contract — Action Contract Regression Repair
+
+## Objective
+
+Fully repair the current AIOS Action runtime/contract overlay regressions on the single server, without modifying protected refs directly and without introducing new infrastructure. The task is not complete until the deployed staging/action overlay passes all acceptance gates.
+
+## Authority and scope
+
+- Repository: `aios/aios`
+- Base at task creation: `3244f0f17f8845592ac94d585f5ebd65693c9f29`
+- Governed task: `fix-action-contracts-20260825-1407`
+- Target branch: `agent/fix-action-contracts-20260825-1407`
+- Protected refs must not be directly written: `main`, release tags, baseline registry, production runtime.
+- No new SaaS, database, agent framework, or monitoring platform may be introduced.
+
+## Non-interactive rules
+
+The Agent must run the whole flow unnattended:
+
+1. Collect facts.
+2. Determine root causes.
+3. Make the smallest correct changes.
+4. Run unit/integration/contract tests.
+5. Deploy to staging only.
+6. Restart only the affected non-production services.
+7. Run the full Action smoke suite.
+8. On failure, automatically collect logs, diagnose, fix, and retry.
+9. If a change causes a new regression, automatically roll back the staging change to the previous known-good configuration and record the failure.
+10. Stop only if an owner decision is required for a high-risk, irreversible, or production-boundary action.
+
+## Fact collection — required before editing
+
+Record all of the following in the final evidence bundle:
+
+- `id`, `hostname`, `uname -a`, `date --iso-seconds`
+- `git rev-parse --show HEAD` for authority worktree and running overlay source
+- `git status --porcelaine=v2`
+- `git remote -v`
+- current systemd service unit(s), drop-ins, Environment/EnvironmentFile sources for GitOps/Bredge/release services
+- `systemctl show <affected-service>` including `User=`, `Group=`, `Environment=`, `EnvironmentFile=`, `ExecStart=`
+- resolved Gitea API base URL after env/config expansion; redact secrets but not scheme/host
+- `stat -c, `namei -l`, `getfacl`, als -ld on `/var/lib/aios-gitops/silent-release` and its parents
+- find Action OpenAPI/schema generator and runtime operation definitions for `commitFilesGoverned`
+- find the release version validator(s) and all callers of `getTagPublicationStatus`
+- find `reconcileGitOpsJob` implementation and durable binding validation logic
+- find `getDiff  implementation and transport output limits
+
+Do not edit any file until the actual implementation and configuration sources have been located.
+
+## Repair 1 — Gitea API URL
+
+Symptoms:
+
+- `getReleaseConsistency` → `Gitea API URL must be HTTP(S)`
+- `runReleaseAcceptance` → `Gitea API URL must be HTTP(ÊX
+
+Required behavior:
+
+- Determine which env/config key is projected into the current contract overlay.
+- Compare the deployed overlay with V2R2C1 known-good configuration/deployment manifests.
+- Restore a valid `HTTP://` or `HTTPS://` Gitea API base URL.
+- Add startup config validation so invalid schemes fail at health/startup with a config-specific message, not during a release check.
+- Never hard-code a different Gitea host if the existing deployment already has a single authoritative source.
+
+## Repair 2 — durable release state permissions
+
+Symptom:
+
+- `getReleaseSaga` → `Permission denied: '/var/lib/aios-gitops/silent-release'`
+
+Required behavior:
+
+- Identify the actual runtime service User/Group.
+- Grant only the required traverse/read/write permissions for the durable state directories the service must use.
+- Prefer ownership + group mode or a specific ACL; keep the directory non-world-writable.
+- Persist the permission in deployment/install logic so restart/reboot does not regress.
+- Verify create/read/update of a staging-only saga state file under the service identity.
+
+## Repair 3 — release version contract
+
+Symptom:
+
+- `getTagPublicationStatus("V2R2C1")` → `invalid release version`
+- The same runtime exposes `V2R2C1` as `approved_release_version`.
+
+Required behavior:
+
+- Locate all version validators; consolidate onto one canonical parser.
+- Accept the AIOS canonical namespace `^V[0-9]+R[0-9]+C[0-9]+$`.
+- Preserve any additional already-supported legacy formats unless they are security-sensitive.
+ - Add contract tests proving that the version accepted by capabilities is accepted by status, candidate, consistency, acceptance, and tag publication.
+
+## Repair 4 — `commitFilesGoverned` schema parity
+
+Symptom:
+
+- Runtime capability metadata requires `files`.
+- Published Action tool schema does not expose `files`.
+- Call reaches Bridge and fails `BRIDGE_REQUEST_FIELDS_MISSING`.
+
+Required behavior:
+
+- Find the canonical runtime operation contract.
+- Generate the external tool schema from the same source of truth; do not manually copy a parallel schema.
+- `files` must be required and must represent a list of file objects with at least `path` and `content_base64`.
+- Add a parity test that compares runtime required fields with published Action required fields.
+- Add a real governed commit test that writes two test files to an isolated `agent/` ibranch and verifies remote OID.
+
+## Repair 5 — terminal reconciliation
+
+Symptom:
+
+- A governed job read back as `COMPLETED' but `reconcileGitOpsJob` failed `DURABLE_BINDING_INVALID`.
+
+Required behavior:
+
+- Reconciling a terminal successful job must be idempotent.
+- An expired writer lease must not invalidate a durable binding for a job that is already terminal.
+- Active-job reconciliation may require a live lease; terminal read-back must not.
+- Add cases for COMPLETED, FAILED, CANCELLED / equivalent terminal states.
+
+## Repair 6 — bounded `getDiff` output
+
+Symptom:
+
+- Large valid diffs fail with `ResponseTooLargeError` or `GIT_OUTPUT_LIMIT_EXCEEDED`.
+
+Required behavior:
+
+- Do not load unbounded diff text into the Action response.
+- Return bounded summary data: commit identities, changed paths/stats, total bytes, and `truncated: true` when the full patch exceeds the safe limit.
+- If pagination already exists in the contract use it; otherwise prefer deterministic truncation over a breaking schema change.
+- Add tests for small, empty, and oversize diffs.
+
+## Staging deployment procedure
+
+1. Run the existing mandatory test suite before modification; record baseline.
+2. Apply code and config changes only on the governed branch/worktree.
+3. Run focused regression tests.
+4. Run the full mandatory suite.
+5. Build the staging contract overlay using the repository's existing build/deploy path.
+6. Deploy to staging/non-production only.
+7. If systemd units are changed: `systemctl daemon-reload`, then restart only the affected staging services.
+8. Wait for the existing health endpoint/runtime status to become healthy.
+9. Run the acceptance suite below.
+
+If any step fails:
+- collect `journalctl` logs and relevant app logs;
+- diagnose root cause;
+- automatically repair and retry when non-destructive;
+- if a new change breaks staging, restore the previous staging artifact/config and restart the affected service;
+- never silently continue after a failed gate.
+
+## Acceptance suite
+
+All of the following must pass on the same deployed staging overlay:
+
+- Runtime status is `active` and healthy after restart.
+- Gitea Git/API readback works from the runtime service identity.
+- `getReleaseConsistency(V2R2C1, 998d30304787e31e5ae607c0bd86b5edb2b0e5ad, a8b906d1bc24088c19647e98de6a679268f6d0a2, approved_plan) returns a structured result and reaches evaluation.
+- `runReleaseAcceptance` for the same identities reaches policy evaluation, not URL validation error.
+- `getTagPublicationStatus("V2R2C1")` returns structured state, not `invalid release version`.
+- `getReleaseSaga` for a nonexistent candidate returns NOT_FOUND/empty-state semantics, not filesystem permission failure.
+- `commitFilesGoverned` exposes its required `files` parameter in the published Action schema.
+ - A real two-file governed commit to an isolated `agent/` branch succeeds and remote branch OID matches.
+- Resuming a COMPLETED job returns the existing `JOB_TERMINAL` semantics or idempotent success as designed.
+- Reconciling a COMPLETED governed job is successful/idempotent and does not require an active lease.
+- Small/empty `getDiff  still works.
+- Large `getDiff` returns bounded output with truncation metadata instead of a transport exception.
+- Existing protected-ref controls remain unchange: no direct main/tag/baseline/production write.
+
+## Restart / reboot persistence
+
+After the first full pass:
+
+- Restart the staging Action/Bridge/release services one more time without changing files.
+- Rerun the acceptance suite.
+- Permissions, Gitea URL, and schema must still be correct after restart.
+- If the repository already has a safe staging reboot test, run it as well.
+
+## Evidence and completion
+
+Create a single durable report in the repository, e.g. `reports/action-contract-repair-evidence-20260825.md`, containing:
+
+- pre-change facts
+- root cause for each regression
+- files changed and why
+- config/permission changes
+- test commands and exact results
+- staging deployment identity (commit/artifact/config digest)
+- restart-persistence results
+- final Action smoke results
+- any remaining risks
+
+Commit all source, test, deployment config, and runbook changes to the governed task branch. Do not mark the task SUCCEEDED until all acceptance gates pass on the actually deployed staging overlay.
+
+## Automatic rollback conditions
+
+Automatically roll back the staging deployment if any of the following occur:
+
+- service fails to become healthy after restart
+- protected-ref write boundary is broken
+- Gitea readback that worked before the change stops working
+- durable saga state cannot be read or recovered
+- mandatory test suite regresses below the pre-change baseline
+
+Do not automatically roll back an existing production release. Rollback here refers only to the staging overlay/service configuration changes made by this task.
+
+## 2026-08-25 execution record
+
+The repair branch was deployed through the existing immutable staging builder. The final source code before the evidence commit was `2ec49005bde44f6981b14351500847d594e0276c`; the deployed artifact was built from that source with SHA256 `f67aed6cc0cce1f08197485c3eea204d3ef4d3989f44dc98e8ea2691e5886cbf`. The final staging drop-ins use a lexically highest `zzzz...-999.conf` layer so they override earlier diagnostic overlays.
+
+The runtime configuration is staging-only: `User=aiman`, `Group=gitops`, API base `https://g.cnnetmkt.top/git/api/v1`, baseline authority `/var/lib/aios-gitops/model-api-staging/baseline/current.json`, and read/write access to the staging state plus the authoritative bare repository required by the governed Writer/CAS path. No `main`, protected tag, baseline registry, or production write is enabled.
+
+The release executor now binds both the configured staging baseline and the immutable runtime package's `versions/V2R2C1.json` projection. The bridge passes `AIOS_GITOPS_BASELINE_AUTHORITY` into `RuntimeConfig`; this prevents release consistency and acceptance from falling back to missing publication-workspace files.
+
+The final acceptance result is recorded in `reports/action-contract-repair-evidence-20260825.md`. Contract smoke is green, and release consistency is `PASS`; release acceptance is structured policy output but remains `accepted=false` because the pre-existing publication state is `REMOTE_PUSH_PENDING` for the protected `V2R2C1` tag. The task must therefore remain `NEEDS_REWORK` until an authorized owner resolves that independent protected-tag state.

+# Agent Execution Contract — V2R2C2 Control-Plane Convergence
+
+## Objective
+
+Complete the AIOS Phase -1 authority/runtime/contract convergence on the existing
+single server with no interactive prompts. The source integration branch already
+contains the staging-validated Action contract repair lineage plus the new minimal
+convergence contracts. The Agent's job is to verify, finish the one remaining
+release-publication reconciliation defect if it is still reproducible, build and
+deploy **staging only**, prove the same-source runtime, and return machine evidence.
+
+This is not authorization to modify production, protected tags, production baseline,
+or `main` directly.
+
+## Canonical identities
+
+- Repository: `aios/aios`
+- Authoritative main observed at task start:
+  `3244f0f17f8845592ac94d585f5ebd65693c9f29`
+- Production baseline: `V2R2C1`
+- Production target:
+  `998d30304787e31e5ae607c0bd86b5edb2b0e5ad`
+- Production evidence closure:
+  `a8b906d1bc24088c19647e98de6a679268f6d0a2`
+- Approval plan:
+  `sha256:c0df52008ae7f64cec5ee2d28947aa7b892066c670ab8295e4549140b1a7500e`
+- Staging repair source lineage:
+  `174e64dd0218cef6d49dd13d58bbd90c78fecadd`
+- Integration branch:
+  `agent/v2r2c2-convergence-integration-20260825`
+- Integration branch OID at handoff:
+  `7526fef619edd8170c03c31a87e32cd1ea52a4ec`
+
+## Code already completed
+
+The integration branch includes the complete governed staging repair lineage rooted
+at the authoritative main revision, including:
+
+- canonical release-version validation;
+- startup-safe Gitea API URL validation;
+- operation contract metadata and `commitFilesGoverned` schema parity;
+- bounded `getDiff`;
+- idempotent terminal job reconciliation;
+- CREATE_NEW branch CAS recovery;
+- release baseline/version projection;
+- external governed-read routing;
+- canonical release consistency routing;
+- durable NOT_FOUND release-saga semantics.
+
+It also adds:
+
+- `active-runtime/app/aios_convergence_contracts.py`
+- `tests/test_convergence_contracts.py`
+
+The new convergence contracts deliberately have no external side effects. They add:
+
+- fail-closed `AcceptanceVector` / `AcceptanceResult`;
+- domain-preserving final-writer ownership validation;
+- `DesiredState` / `ObservedState`;
+- pure reconciliation planning with stable idempotency identity;
+- `SideEffectReceipt`;
+- `ContinuationManifest`.
+
+Local isolated validation before handoff: `8 passed`.
+
+## Current observed runtime facts
+
+At handoff:
+
+- model API staging service is active at source
+  `174e64dd0218cef6d49dd13d58bbd90c78fecadd`;
+- external `getControlPlaneSnapshot` is reachable;
+- external `getGovernedWriteCapabilities` is reachable;
+- `getReleaseConsistency(V2R2C1, ...)` returns `status=PASS` and all checks true;
+- remote/local tag object is
+  `07fc2746b688f5f243f29b39de39f32edc3dd9d2`;
+- peeled target is
+  `998d30304787e31e5ae607c0bd86b5edb2b0e5ad`;
+- production health returns HTTP 200 and the same target/artifact identity;
+- `runReleaseAcceptance` still returns `accepted=false` despite consistency PASS;
+- `getTagPublicationStatus(V2R2C1)` currently returns `UNKNOWN`;
+- `getControlPlaneSnapshot.runtime.runtime_release_commit` reports
+  `2ec49005bde44f6981b14351500847d594e0276c`, while the model API runtime
+  reports `174e64dd0218cef6d49dd13d58bbd90c78fecadd`.
+
+Those last two facts are the remaining convergence defects.
+
+## Non-interactive execution policy
+
+Run continuously without asking the Owner to type "continue".
+
+Automatically:
+
+1. collect facts;
+2. run tests;
+3. diagnose failures;
+4. make the smallest correct repair;
+5. rebuild immutable staging artifacts;
+6. deploy/restart only affected staging services;
+7. observe external truth;
+8. retry recoverable failures;
+9. roll back newly introduced staging regressions;
+10. produce final evidence.
+
+Stop only for:
+
+- authority/approval that cannot be satisfied by existing bindings;
+- irreversible production change;
+- protected-ref mutation;
+- security-boundary change;
+- genuine goal ambiguity;
+- no-progress after bounded diagnosis/repair attempts.
+
+## Phase A — pre-edit facts
+
+Before any further edit, persist:
+
+- current authoritative HEAD;
+- integration branch OID and remote readback;
+- `git merge-base --is-ancestor 3244f0f... 7526fef...`;
+- staging service source/artifact identity for both model API and Bridge;
+- systemd unit + drop-in ordering for both services;
+- exact environment sources for baseline, Gitea API, state roots and PYTHONPATH;
+- current release consistency, acceptance and tag-publication status;
+- current control-plane snapshot;
+- current governed-write capabilities operation contracts.
+
+Do not trust a report if a direct runtime observation is available.
+
+## Phase B — mandatory tests
+
+Run at minimum:
+
+```text
+PYTHONPATH=active-runtime/app python3 -m pytest -q   tests/test_convergence_contracts.py   tests/test_action_contract_regressions.py   tests/test_bridge_v2_governed_http_bootstrap.py
+
+PYTHONPATH=active-runtime/app python3 -m pytest -q   tests/test_silent_release_execution_readiness.py   tests/test_silent_release_controller.py   tests/test_silent_release_hardening.py   tests/test_silent_release_production_contract.py   tests/test_chatgpt_actions_tag.py   tests/test_gitea_tag_publication.py   tests/test_authoritative_git_context.py
+```
+
+Then run the repository-wide suite. Compare failures to the persisted pre-existing
+baseline. No new regression is allowed.
+
+## Phase C — release-publication truth reconciliation
+
+Only execute this code repair if the following remains simultaneously true on the
+same staging runtime:
+
+```text
+getReleaseConsistency.status == PASS
+runReleaseAcceptance.accepted == false
+getTagPublicationStatus(V2R2C1) in {UNKNOWN, REMOTE_PUSH_PENDING}
+```
+
+### Required semantics
+
+Do **not** hard-code `accepted=true` and do not reinterpret UNKNOWN as PASS.
+
+The publication controller must reconcile durable publication state from observed
+external truth:
+
+1. Resolve the approved version binding.
+2. Read authoritative local tag object and peeled commit.
+3. Read Gitea tag object and peeled commit.
+4. Read registry/baseline approved tag object and target.
+5. Compare all identities to the approved release binding.
+6. If every required observation is present and exactly equal:
+   - persist the existing terminal-success publication state used by the codebase
+     (`PUBLISHED`/equivalent);
+   - mark the transition as observation-only/reconciled;
+   - record the observed tag object, peeled target, repository identity and evidence;
+   - perform **no tag create/push**.
+7. If any identity differs:
+   - fail closed as drift/conflict;
+   - never mutate the protected tag.
+8. If any required observation is unavailable:
+   - remain `UNKNOWN`/reconciling;
+   - do not mark accepted.
+9. Replaying reconciliation must be idempotent and must not create a second
+   side effect.
+
+`runReleaseAcceptance` may return accepted only after both:
+
+```text
+release consistency == PASS
+AND reconciled publication state == terminal success
+```
+
+### Mandatory regression tests
+
+Add focused tests for:
+
+- missing local publication journal + exact observed remote tag -> terminal success;
+- stale `REMOTE_PUSH_PENDING` + exact observed remote tag -> terminal success;
+- remote tag object mismatch -> fail closed;
+- peeled target mismatch -> fail closed;
+- Gitea observation unavailable -> UNKNOWN, not accepted;
+- replay after reconciled success -> identical durable receipt, no tag write/push;
+- existing protected tag is never force-updated or deleted.
+
+Use the existing `TagPublisher`/publication store and existing reconciliation/state
+model. Do not create a second release database or a second release controller.
+
+## Phase D — same-source staging convergence
+
+Build from integration branch OID after tests. Deploy the same immutable artifact
+lineage to every staging component participating in these Actions.
+
+Acceptance requires the externally visible snapshot to stop presenting mixed
+source identity. At minimum model API and Bridge must report the same intended
+source/build identity or explicitly report component-level identities without
+claiming a single aggregate runtime commit.
+
+Do not hide component drift by overwriting the snapshot value.
+
+Preferred fix if the snapshot currently has only one `runtime_release_commit`:
+extent it to expose component identities, for example:
+
+```text
+runtime.components.model_api.source_oid
+runtime.components.bridge.source_oid
+runtime.aggregate_drift_status
+```
+
+Aggregate PASS is legal only if the required components are on the approved
+compatible source set.
+
+## Phase E — staging smoke
+
+On the deployed staging artifact run:
+
+- runtime status;
+- control-plane snapshot;
+- governed-write capabilities;
+- release consistency;
+- release acceptance;
+- tag publication status;
+- nonexistent release saga;
+- bounded large diff;
+- completed-job reconcile idempotency;
+- isolated two-file governed commit on a throwaway `agent/` branch.
+
+Required end state:
+
+```text
+release_consistency = PASS
+release_acceptance.accepted = true
+tag_publication = terminal success
+control_plane_snapshot = reachable
+governed_capabilities = reachable
+runtime_component_drift = PASS
+legacy_writes = false
+force_push = false
+main_write = false
+tag_write = false
+baseline_write = false
+production_write = false
+```
+
+## Phase F — restart persistence
+
+Restart only affected staging services, without changing files.
+
+Rerun Phase E. All identities and outcomes must remain stable.
+
+## Governance and branch handling
+
+Do not directly modify `main`, `V2R2C1`, the production baseline registry or
+production services.
+
+The current Bridge writer binding has a known limitation: after a successful
+single-file CAS commit, reacquiring the same task lease can return the original
+expected branch OID, and rebinding the same task/generation can conflict.
+
+Do not work around that with direct Git writes.
+
+For source changes use the existing governed task/lease/commit flow. If the platform
+requires one governed task binding per branch advance, create an explicitly named
+follow-up governed task on the **same branch**, with:
+
+- `base_oid` = previously verified branch OID;
+- `expected_branch_oid` = same previously verified branch OID;
+- same repository and branch;
+- no protected-ref write.
+
+Record this as `TASK_BINDING_EXPECTED_OID_NOT_ADVANCING` evidence.
+
+## Final evidence
+
+Commit a durable report:
+
+`reports/v2r2c2-control-plane-convergence-evidence-20260825.md`
+
+It must contain:
+
+- pre-change facts;
+- exact commits and changed paths;
+- all test commands/results;
+- release-publication reconciliation proof;
+- proof that no protected tag write occurred during observation reconciliation;
+- build artifact SHA;
+- staging component source identities;
+- pre/post restart smoke;
+- branch authority/Git remote/API readback;
+- remaining known risks;
+- final disposition.
+
+Do not declare `SUCCEEDED` unless every required end-state line in Phase E is
+proven from the actually deployed staging runtime.
+
+Production promotion is a separate Owner-approved release step and is **not** part
+of this execution contract.
