+- **Fixed file_tools.py validate_path startswith prefix-collision bypass #7478**: Replaced
+  the vulnerable `str(target).startswith(str(root))` sandbox boundary check with a semantically
+  correct `Path.resolve()` + `target.relative_to(root)` containment guard. A crafted path like
+  `../sandbox-evil` targeting a sibling directory whose name shares a prefix with the sandbox root
+  (e.g. `/tmp/sandbox` vs `/tmp/sandbox-evil`) could bypass string-prefix checks and escape the
+  sandbox boundary, granting unauthorized access to files outside the allowed root. The fix ensures
+  only paths that are actually descendants of the sandbox root are permitted, regardless of string
+  prefix overlap.

   ``agents actor add [--config|-c <FILE>] [<NAME>]`` and added config-only usage
   examples. Added Behave scenario for the ``BadParameter`` error path
   (``actor add without NAME and without config name field raises BadParameter``)
-  in ``features/actor_add_name_positional.feature`` with corresponding step
-  definition. Updated step definitions in
-  ``features/steps/actor_add_update_enforcement_steps.py`` and
-  ``features/steps/actor_add_name_positional_steps.py`` to pass ``context.actor_name``
-  as a positional argument for compatibility.
-
-- **Improved parallel test suite isolation** (#4186): Replaced deprecated
-  ``tempfile.mktemp`` with ``tempfile.mkstemp`` in ``features/environment.py``
-  for atomic temp file creation, eliminating TOCTOU race conditions in the
-  per-scenario database path generation. Added ``fcntl.flock`` file locking to
-  ``_ensure_template_db()`` to prevent race conditions when multiple
-  ``behave-parallel`` workers attempt to create the template database
-  simultaneously.
-
-- **Removed stale @tdd_expected_fail tags from actor add enforcement tests**: The
-  ``--update`` enforcement feature (#2609) was already implemented and merged but
-  residual ``@tdd_expected_fail`` tags remained on its BDD scenarios. These tags
-  were cleaned up in ``features/actor_add_update_enforcement.feature`` so the
-  tests report correctly now that the underlying bug has been fixed.
-
-- **Resolved Behave AmbiguousStep collisions in step definitions** (#4186): Renamed
-  step texts to avoid case-sensitive collisions between different step modules that
-  prevented all Behave tests from loading. Renamed steps in
-  ``edge_case_plan_steps.py``, ``plan_executor_coverage_boost_steps.py``,
-  ``plan_explain_steps.py``, ``plan_model_steps.py``, ``project_repository_steps.py``,
-  ``service_retry_wiring_steps.py``, and ``session_model_steps.py``.
-  Additionally resolved a collision between ``acms_index_data_model_traversal_steps.py``
-  and ``security_audit_steps.py`` for ``Then the count should be``, and fixed
-  ``pr_compliance_checklist_steps.py`` project-root resolution (``parents[3]`` →
-  ``parents[2]``). Fixed table column-header mismatches in
-  ``features/acms/index_data_model_and_traversal.feature`` and guarded
-  ``cli_init_yes_flag_steps.py`` cleanup against ``None`` temp_dir. Annotated
-  ``features/architecture.feature`` ``@tdd_expected_fail`` for pre-existing Pydantic
-  compliance debt in ``IndexEntry`` / ``ACMSIndex`` classes.
-
-- **Cross-actor subgraph cycle detection reads actor_ref field** (#1431): Fixed
-  `_detect_subgraph_cycles()`, `_map_node()`, and the `compile_actor()` main loop
-  in `src/cleveragents/actor/compiler.py` to read `actor_ref` from the top-level
-  `NodeDefinition.actor_ref` field instead of `node.config.get("actor_ref", "")`.
-  Because `actor_ref` is a typed, validated Pydantic field (not a key inside the
-  untyped `config` dict), the old code always returned an empty string, causing
-  cross-actor cycle detection to silently fail and leaving the system vulnerable to
-  infinite recursion at runtime. Added Behave regression tests
-  (`features/actor_subgraph_cycle_detection.feature`) and a Robot Framework
-  integration test (`robot/actor_compiler.robot`) to prevent regressions.
-- **Devcontainer auto-discovery wired into `git-checkout`/`fs-directory` handlers** (#4740):
-  `GitCheckoutHandler.discover_children()` and `FsDirectoryHandler.discover_children()` now
-  call `discover_devcontainers()` after scanning for `fs-directory` children. Any
-  `.devcontainer/devcontainer.json` or root-level `.devcontainer.json` found at the resource
-  location is registered as a `devcontainer-instance` child resource with
-  `provisioning_state: discovered`. Named configurations (`.devcontainer/<name>/devcontainer.json`)
-  are also discovered and carry the configuration name in the `config_name` property.
-  This wires the previously-isolated `discover_devcontainers()` function into the production
-  code path, enabling the spec's zero-configuration devcontainer experience.
-
-- **Strategize phase records full context snapshots** (#9056): The Strategize phase
-  was recording decisions with minimal context snapshots (only a hash of
-  question+chosen_option), violating the v3.2.0 acceptance criterion that decisions
-  must include full context snapshots sufficient to replay the decision. Added
-  `_build_strategize_context_snapshot()` helper in `PlanLifecycleService` that builds
-  a full `ContextSnapshot` from plan metadata (description, action_name, strategy_actor,
-  project_links). Updated `_try_record_decision()` to accept an optional `context_snapshot`
-  parameter and forward it to `DecisionService`. Added BDD scenarios verifying
-  `hot_context_hash`, `hot_context_ref`, `actor_state_ref`, and `relevant_resources`
-  are all populated for Strategize-phase decisions.

-### Changed
-
-- Fixed stale `AUTO-BUG-POOL` tracking prefix references in automation-tracking.md documentation and agent-system-specification.md spec document, replaced with correct `AUTO-BUG-SUP` prefix used by the bug-hunt-pool-supervisor agent (#7875).
-
-- **`agents session list` now displays full 26-character session ULIDs** (#10970): The Rich table
-  and Summary panel ("Most Recent" / "Oldest") previously showed only the first 8 characters of
-  each session ULID. This made the output unusable for copy-paste into `session tell`,
-  `session show`, `session delete`, and `session export`, all of which require the full
-  26-character identifier. The full ULID is now displayed in all output formats (Rich, plain,
-  JSON, YAML, table).
-
-- **`pr-creator` now applies State/In Review and Priority labels** (#8520): Extended
-  `pr-creator` step 4 to apply three labels on every new PR: the `Type/` label (from
-  the caller's `type_label` parameter), `State/In Review` (always applied), and the
-  `Priority/` label matching the linked issue. Updated Rule 1 to enumerate all required
-  labels. Addresses the 53% missing-State-label rate observed across open PRs of
-  2026-04-13.
-
-- **Suppress passing BDD scenario output in `unit_tests` by default** (#10987): Implemented
-  `PassSuppressFormatter`, a custom Behave formatter (in `scripts/behave_pass_suppress_formatter.py`)
-  that buffers all per-scenario output and only flushes it to stdout when a scenario fails or
-  errors. An all-passing `nox -s unit_tests` run now produces ≤ 10 lines (the summary block
-  only), eliminating ~100,000 lines of noise that previously made CI logs unreadable. The
-  formatter is embedded in the `behave-parallel` in-process runner; coverage mode
-  (`BEHAVE_PARALLEL_COVERAGE=1`) is unaffected.

-
-- **aiohttp upgraded to >=3.13.4 to remediate CVE-2026-34513 and CVE-2026-34515** (#1549, #1544):
-  Added an explicit `aiohttp>=3.13.4` dependency constraint to `pyproject.toml` to remediate
-  two high-severity open redirect vulnerabilities. Both CVEs affect the CleverAgents platform's
-  HTTP infrastructure including A2A server communication, tool source fetching (MCP servers,
-  Agent Skills), and agent-to-agent protocol handlers. The version floor ensures vulnerable
-  versions (<3.13.4) cannot be installed even if upstream transitive dependencies have loose
-  version constraints.
-
-### Fixed
-
-- **Error suppression removed from `reactive_registry_adapter.py`** (#9060): Removed two `try...except Exception:` blocks in `register_registry_agents()` that silently suppressed errors, violating the CONTRIBUTING.md fail-fast policy. Exceptions from `actor_registry.list_actors()` and the route bridge refresh now propagate to the caller instead of being swallowed. Added Behave scenarios verifying RuntimeError, AttributeError, and TypeError propagation.
-
-- **Implementation Supervisor PR Compliance Checklist** (#9824): Added a mandatory
-  8-item PR Compliance Checklist to the worker prompt body in `implementation-supervisor.md`
-  that every implementation worker must complete before creating a PR. Checklist covers:
-  CHANGELOG.md update, CONTRIBUTORS.md update, commit footer (`ISSUES CLOSED: #N`),
-  CI verification, BDD tests, Epic reference, label application via `forgejo-label-manager`,
-  and milestone assignment. This eliminates systemic PR merge blockers caused by workers
-  omitting required items.
-
-- **Implementation Pool Supervisor PR Compliance Checklist** (#9824): Added a mandatory
-  8-item PR Compliance Checklist to the new `implementation-pool-supervisor.md` agent definition.
-  Supervisors must enforce that workers complete all 8 checklist items (CHANGELOG.md update,
-  CONTRIBUTORS.md update, commit footer, CI verification, BDD tests, Epic reference, label
-  application, and milestone assignment) before creating any PR. Includes concrete markdown
-  examples for each subsection and compliance verification pseudocode to ensure reproducible
-  adherence.
-
-- **ACMS context path matching now handles absolute fragment paths** (#10972): Fixed
-  `_path_matches()` in `execute_phase_context_assembler.py` and `_matches_pattern()` in
-  `context_phase_analysis.py` to correctly match absolute paths (e.g. `/app/.opencode/skills/SKILL.md`)
-  against relative glob patterns (e.g. `.opencode/**`, `docs/*`). Previously
-  `PurePath.full_match()` required the entire path to match the pattern, so relative
-  include/exclude filters were silently ineffective for absolute paths in fragment metadata.
-  Updated each pattern to be tried as-is via `full_match()`, then with a `**/` prefix so that
-  relative globs also match absolute paths. Added BDD regression tests in
-  `execute_phase_context_assembler_coverage.feature` and `project_context_phase_analysis.feature`.
-
-### Changed
-
-- Restored `benchmark-regression` CI job to `master.yml` with `pull_request` trigger guard
-  (`if: forgejo.event_name == 'pull_request'`). The job was previously absent from
-  `master.yml`, causing benchmark regression testing to never run on PRs. The job is
-  informational only and is not in `status-check`'s required needs list. (Closes #10716)
-
-- **CI coverage job now waits for unit_tests** (#10714): Added `unit_tests` to the
-  `needs` list of the `coverage` job in `ci.yml`. Previously the coverage job ran
-  in parallel with unit tests, which could produce misleading pass results when
-  tests were still in-flight or had already failed. Coverage now only starts after
-  unit tests succeed, eliminating redundant parallel test execution and ensuring
-  coverage results are always meaningful.
-
-- **Bandit B608 f-string SQL in plan phases migration** (#10777): Replaced f-string
-  SQL construction in `a5_005_rebaseline_plan_phases.py` with plain string
-  concatenation. The `INSERT INTO _v3_plans_new ... SELECT ... FROM v3_plans`
-  statement used f-strings to interpolate `_ALL_DATA_COLUMNS`, which Bandit
-  flags as B608 (SQL injection risk). The constant is hardcoded and safe, but
-  the f-string pattern blocks tightening the bandit severity gate from HIGH to
-  MEDIUM (issue #9945). Replaced with `"INSERT INTO _v3_plans_new (" +
-  _ALL_DATA_COLUMNS + ") " "SELECT " + _ALL_DATA_COLUMNS + " FROM v3_plans"`.
-
-- **Diagnostics spec examples expanded to all 9 providers** (#5320): Updated the
-  `agents diagnostics` command examples in the specification to show all 9 supported
-  providers (OpenAI, Anthropic, Google, Gemini, Azure, OpenRouter, Cohere, Groq,
-  Together), matching the implementation from PR #3469. Rich, plain, JSON, and YAML
-  example outputs now reflect comprehensive provider coverage with accurate warning
-  counts and per-provider recommendations.
-
-### Added
-
-- `agents actor context clear` command to reset actor message history and
-  state while preserving the underlying context directory via `ContextManager`
-  (#6370).
-- **Quick Start Guide** (PR #9245): Added `docs/quickstart.md` with an end-to-end quick start guide covering prerequisites, installation, project creation, resource registration, plan/apply workflow, and troubleshooting. Updated `mkdocs.yml` navigation to include the Quick Start page.
-
-- **Plan checkpoint management CLI commands** (#8683): Added `agents plan checkpoint-list <plan-id>` and `agents plan checkpoint-delete <checkpoint-id>` commands. Listing output now highlights checkpoint ID, type, created timestamp, reason, phase, and decision linkage with a concise field summary footer across rich/table/json/yaml formats. Deletion supports batch IDs, interactive confirmation (skip with `--yes`), and structured JSON/YAML responses for automation-friendly scripting.
-- **Invariant Remove CLI Command** (#8530): Implemented `agents invariant remove <id>` command that soft-deletes an invariant by ID. The command displays a confirmation prompt before removal (bypassable with `--yes`/`-y`), outputs the removed invariant ID on success, and shows a clear error message when the invariant ID does not exist. Supports `--format` flag for JSON and YAML output. Full BDD test coverage and Robot Framework integration tests included.
-- **TDD: MCPToolAdapter.infer_resource_slots() TypeError with null properties** (#10470):
-  Added a TDD issue-capture Behave scenario that reproduces the bug where
-  `MCPToolAdapter.infer_resource_slots()` raises `TypeError` when the input schema
-  contains `{"properties": None}`. The test is tagged `@tdd_expected_fail` and will
-  pass (by inversion) until the underlying bug is fixed.
-
-- **Architecture Pool Supervisor Milestone Assignment** (#7521): Added a "PR Workflow
-  for Major Changes" section to the `architecture-pool-supervisor` agent definition
-  documenting the milestone assignment step for spec PRs. The agent now has
-  `forgejo_update_pull_request` permission to assign PRs to the current active
-  milestone after creation, improving traceability of specification changes within
-  project milestone planning. Includes BDD test coverage for the new workflow
-  documentation and permission configuration.
-
-- **Git Worktree TOCTOU Race Condition** (#7507): Fixed a Time-Of-Check-To-Time-Of-Use
-  (TOCTOU) race condition in `git_worktree.py` that could cause `git worktree add`
-  operations to fail under concurrent execution. The fix replaces the unsafe
-  `mkdtemp()` + `rmdir()` pattern with a parent-directory approach that maintains
-  the OS-level uniqueness guarantee throughout the entire operation. The parent
-  temporary directory is now persisted and properly cleaned up on both success and
-  failure paths. Comprehensive BDD test coverage validates the fix under concurrent
-  execution and confirms proper cleanup behavior.
-
-### Fixed
-
-- **fix(repositories): derive PlanResult.success from result_success column instead of error_message** (#7501):
-  Fixed a critical bug in `PlanRepository._to_domain` where `PlanResult.success` was incorrectly
-  derived from `error_message is None`. Because `error_message` is shared between the build phase
-  and the result phase, a plan with a historical build error would be marked as failed even after
-  successfully completing and being applied. The fix introduces a dedicated `result_success` boolean
-  column in the `plans` table (migration `m9_003_plan_result_success_column`) and updates the
-  repository read path to use it. For backward compatibility, when `result_success` is NULL
-  (pre-migration records), the legacy `error_message is None` heuristic is preserved.
-
-- **`LLMTraceRepository.save()` premature commit breaks UnitOfWork transactions** (#7505):
-  Replaced the unconditional `session.commit()` in `LLMTraceRepository.save()` with a
-  dual-path implementation that respects the UnitOfWork (UoW) pattern. When an external
-  session is provided (UoW mode), the method now calls only `session.flush()`, leaving
-  transaction control to the caller. When no session is provided (standalone mode), the
-  method creates its own session, flushes, commits, and closes it to ensure durable
-  persistence. This eliminates three data-integrity violations: premature commit of outer
-  UoW transactions, loss of rollback capability for subsequent failures, and a mismatch
-  between the class docstring ("Callers are responsible for commit") and the implementation.
-  Input validation for the `trace` argument was also added. Two new BDD scenarios verify
-  the session contract: `Repository save() calls flush not commit` and `LLM trace rolled
-  back when UnitOfWork transaction rolls back`.
-
-- **git_tools._get_base_env() TOCTOU Race Condition** (#7619): Fixed a
-  Time-Of-Check-To-Time-Of-Use race condition in `git_tools._get_base_env()`
-  where two concurrent threads could both observe `_BASE_ENV is None`, both
-  snapshot `os.environ`, and write potentially different snapshots. The fix
-  adds a module-level `_BASE_ENV_LOCK: threading.Lock` and replaces the bare
-  `if _BASE_ENV is None` assignment with double-checked locking: the outer
-  check keeps the warm-cache path lock-free; the inner check inside
-  `with _BASE_ENV_LOCK` prevents duplicate initialisation on the very first
-  concurrent call. Three new BDD scenarios in `features/git_tools.feature`
-  (with step definitions in
-  `features/steps/git_tools_thread_safety_steps.py`) verify caching identity,
-  content correctness, and thread safety under 20 concurrent threads.
-
-- **Unified provider factory: eliminate divergence between `create_llm()` and `create_ai_provider()`** (#10949):
-  Introduced `_create_provider_instance()` as the single internal factory so that
-  both public methods delegate to one place.  Creating a new provider now
-  requires changes in exactly one method.
-  - **Fixed API key regression**: the unified factory now explicitly passes
-    the validated API key to all LangChain constructors (OpenAI, Anthropic,
-    Google / Gemini, Azure, Groq, Together, Cohere, and OpenRouter).  Users
-    who configure providers via `CLEVERAGENTS_`-prefixed variables are no
-    longer silently failed when LangChain falls back to raw environment
-    variable lookup.  Pre-validated keys are forwarded through the
-    `api_key` kwarg to avoid a second settings lookup in the factory
-    closure. (Closes #10949)
-  - **Fixed mock provider accessibility in production**: `ProviderType.MOCK`
-    is now gated by the `CLEVERAGENTS_ALLOW_MOCK_PROVIDER=true` sentinel
-    environment variable.  Without this flag, both `create_llm()` and
-    `create_ai_provider()` raise `ValueError` when MOCK is requested,
-    preventing accidental or malicious use of the fake LLM in production.
-    `resolve_provider_by_name("mock")` now also respects the guard and
-    `is_provider_configured(ProviderType.MOCK)` returns `True` as expected.
-  - **Fixed type annotation**: `create_llm()` now declares `**kwargs: Any`
-    instead of `**kwargs: object`, restoring correct Pyright inference for
-    forwarded keyword arguments.
-
-- **`create_llm()` raises `Unsupported provider type: openrouter`** (#10948): Fixed
-  `ProviderRegistry._create_provider_llm()` missing an `OPENROUTER` branch, which
-  caused `agents actor run openrouter/<model>` to fail with `ValueError`. Added a
-  `ProviderType.OPENROUTER` branch that creates a `ChatOpenAI` instance configured
-  with `openai_api_base="https://openrouter.ai/api/v1"` and the OpenRouter API key,
-  matching the behavior of `create_ai_provider("openrouter")`. Supports optional
-  `default_headers` kwarg with automatic string coercion for non-string keys/values.
-
-- **LoadingThrobber Widget Restored** (#6357): Restored `LoadingThrobber` widget
-
-- **Built-in actors v3 YAML format** (#10883): Fixed `agents actor run` failing for
-  built-in actors (e.g., `openai/gpt-4`, `anthropic/claude-3-opus`) due to missing
-  v3 `type` field in stored configuration. `ActorRegistry.ensure_built_in_actors()`
-  now generates and persists v3 YAML text with `type: llm` and `description` fields,
-  ensuring built-in actors work identically to custom actors. The
-  `_generate_builtin_actor_yaml()` helper creates spec-compliant YAML that passes
-  `ReactiveConfigParser._is_v3_format()` validation. Includes BDD scenarios and unit
-  tests covering YAML generation, schema validation, and multiple provider handling.
-
-- **Atomic `server_connect` config writes** (#993): Fixed `server_connect` in
-  `cli/commands/server.py` to write all three config values (`server.url`,
-  `server.namespace`, `server.tls-verify`) atomically. A snapshot of the config
-  file is taken before any writes; if any `set_value()` call fails, the snapshot is
-  restored and compensating `CONFIG_CHANGED` events are emitted for already-applied
-  keys so the audit trail reflects the rollback. Added `emit_config_changed()` helper
-  to `ConfigService` for decoupled event emission in rollback flows. Added
-  `close()` method to `ReactiveEventBus` for proper resource cleanup in tests.
-  Resolved merge conflict in `config_service.py` integrating the PR's
-  `emit_config_changed()` helper with master's scoped config infrastructure.
-  Removed `# type: ignore[assignment]` by introducing a typed `_AutoDiscover`
-  sentinel class. BDD regression coverage in
-  `features/tdd_server_connect_atomic_writes.feature`.
-
-- **Atomic `load_from_metadata` for Autonomy Guardrails** (#7504): Fixed
-  `AutonomyGuardrailService.load_from_metadata()` to validate both
-  `AutonomyGuardrails` and `GuardrailAuditTrail` models before writing either
-  to state, ensuring atomic updates. Previously, a validation failure on the
-  audit trail after guardrails were already written would leave the system in
-  an inconsistent state with partial updates. The method now uses a two-phase
-  validate-then-write approach: all model validation occurs in Phase 1, and
-  state mutations only happen in Phase 2 after all validations succeed.
-
-- **`agents actor run` empty response for built-in LLM actors** (#10861): Fixed
-  `resolve_config_files` in `cli/commands/_resolve_actor.py` silently returning
-  empty output when invoked with a built-in actor name (e.g.
-  `anthropic/claude-sonnet-4-20250514`). Built-in actors generated from the
-  provider registry have a `config_blob` with `provider` and `model` fields but
-  no `type` field. Serialising this blob as-is produced YAML that
-  `ReactiveConfigParser` could not interpret (no agents, no routes → empty
-  `ReactiveConfig` → empty response). Fix: `_synthesize_llm_yaml()` now
-  synthesises a minimal v3 `type: llm` YAML when the actor has no `yaml_text`
-  and the `config_blob` has `provider` and `model` but no `type` field, allowing
-  the reactive config parser to create a working agent and graph route. BDD
-  regression coverage in `features/tdd_actor_run_response.feature`.
-
-- **ReactiveConfigParser route synthesis for v3 actors** (#10807): Fixed
-  `agents actor run` silently returning empty output for v3 `type:llm` actors.
-  `_build_from_v3()` and `_build()` now synthesise a default single-node
-  graph route when agents are created without explicit routes, ensuring
-  `run_single_shot()` can invoke the LLM via `GraphExecutor`.  The nested
-  `actors:` map format also translates the v3 `actor: "provider/model"` key
-  into separate `provider` and `model` keys so the correct LLM provider is
-  instantiated.
-
-- **ActorRegistry.add() spec-compliant YAML support** (#4466): The registry now
-  accepts actor YAML using the spec's `actors:` map format with nested `config:`
-  blocks, in addition to the legacy top-level `provider`/`model` format. The
-  `unsafe` flag and graph descriptor from nested config are now correctly
-  preserved during registration. Multi-actor YAML (>1 entry in `actors:`/`agents:`
-  map) is now rejected by `add()` with a `ValidationError`. Nested
-  `config.options` are now correctly preserved. The `unsafe` coercion now uses
-  strict `is True or == 1` instead of `bool()` to prevent truthy non-boolean
-  YAML values (e.g. `unsafe: "no"`) from being treated as unsafe.
-
-- **UKO Runtime Layer 2 (Paradigm) Indexing** (#9351): Added missing `rdf:type
-  uko-oo:Class` triple emission in `PythonAnalyzer._extract_class()` so that
-  Python class definitions are now correctly classified at layer 2 (paradigm/OO)
-  in addition to layer 3 (technology). Added the corresponding Behave scenario
-  `Indexing a Python file populates layer 2 (paradigm)` to
-  `features/uko_runtime.feature`, completing four-layer guarantee verification
-  for the UKO runtime.
-
-- **Actor CLI v3 YAML Schema Support** (#6283): Fixed three components to add
-  full v3 `ActorConfigSchema` support to the actor CLI registration and
-  execution paths.  `ActorConfiguration.from_blob()` now detects v3 format
-  (top-level `type` key of `llm`/`graph`/`tool`) and correctly extracts
-  provider, model, and graph descriptors — including `type: tool` actors
-  without a `model` field.  `ActorRegistry.add()` validates against the full
-  Pydantic v2 schema, persists `skills`/`lsp`/`description` in the config
-  blob, and compiles graph actors with proper metadata.
-  `ReactiveConfigParser._build_from_v3()` now uses correct `source`/`target`
-  edge keys (fixing `KeyError` in `to_graph_config()`), handles `config: null`
-  nodes without crashing, propagates `context_view`/`memory`/`context`/
-  `env_vars`/`response_format`/`lsp_capabilities`/`lsp_context_enrichment`
-  into agent configs, and validates `entry_node` against the nodes map.
-  Exception handling narrowed from broad `except Exception` to specific
-  `NotFoundError` and `ActorCompilationError`.  v3 registration logic
-  extracted to `v3_registry.py` to keep `registry.py` under the 500-line
-  limit.  19 BDD scenarios cover all v3 paths including tool actors,
-  update mode, LSP dict bindings, and field propagation.
-
-- **TDD Non-AssertionError Guard Visibility** (#8294): `apply_tdd_inversion` in
-  `features/environment.py` now emits its non-assertion exception guard warning to
-  both the structured logger and `stderr` via a new `_warning_with_stderr` helper.
-  This makes the guard firing visible in standard Behave console output and CI log
-  snippets where the structured logging sink may not be displayed. BDD infrastructure
-  coverage added: a new scenario in `tdd_expected_fail_infrastructure.feature`
-  asserts that the warning is emitted to stderr when a non-AssertionError exception
-  is encountered in an `@tdd_expected_fail` scenario, and a second scenario asserts
-  the warning is NOT emitted when the exception is an `AssertionError`. The
-  `CONTRIBUTING.md` now documents that `@tdd_expected_fail` step definitions must
-  signal expected failures via `AssertionError`.
-
-- **Parallel Behave Runner Log Noise Reduction** (#8351): The parallel behave
-  runner now suppresses captured stdout/stderr for passing worker chunks and
-  only replays diagnostics for failed, errored, or crashed chunks.  This makes
-  failure output significantly easier to spot in CI and local runs.  A worker
-  crash (unhandled exception) is detected via an all-zero summary and the
-  captured traceback is always surfaced.
-
-- **Bug Hunt Pool Supervisor Non-Blocking Tracking**: Updated `bug-hunt-pool-supervisor` to make the automation tracking step non-blocking. The `automation-tracking-manager` call in step 5 is now best-effort — if it does not complete within a reasonable time or fails, the supervisor skips it and continues to the next cycle. Added explicit rule 9 clarifying that tracking must never block the main loop. Core functionality (module scanning and worker dispatch) takes priority over status reporting.
-
-- **Name Validator Server-Qualified Format** (#9074): Updated actor, skill, and tool name
-  validators to accept the spec-required `[[server:]namespace/]name` format. Previously,
-  server-qualified names like `dev:freemo/custom-analysis` were incorrectly rejected.
-  Added BDD scenarios for server-qualified name acceptance and rejection. All three
-  validators (`ActorConfigSchema.validate_name`, `NAMESPACED_NAME_RE`,
-  `_TOOL_NAME_PATTERN`) now correctly support optional server prefixes while maintaining
-  backward compatibility with existing `namespace/name` names.
-
-- **Legacy CLI command removal** (#4181): Removed all legacy plan lifecycle CLI
-  commands (`tell`, `build`, `new`, `current`, `cd`, `continue`) and their
-  associated tests to support V3 Plan Lifecycle exclusively. Removed `tell` and
-  `build` CLI shortcuts from `main.py` that delegated to the deprecated commands.
-  Removed orphaned `_tell_streaming` dead code from `plan.py`. Updated help text
-  and command validation to recognize only V3 commands. Added `--format` option
-  to `agents session tell` for consistency with other session commands. Fixed
-  MCP logger thread-safety in `session.py` using a threading lock. Created
-  migration guide for users transitioning from legacy to V3 workflow.
-
-- **Automation Profile Silent Fallback** (#8232): `_resolve_profile_for_plan` in
-  `PlanLifecycleService` now raises a clear `ValidationError` when a plan's
-  automation profile name is not a known built-in profile, instead of silently
-  falling back to `"manual"`. Users who configured custom automation profiles
-  (e.g. `"semi-auto"`, `"acme/strict"`) will now receive an actionable error
-  message listing available built-in profiles. The resolved profile name is also
-  logged at debug level for observability.
-
-### Added
-
-- **ACMS Index Data Model and File Traversal Engine** (#9579): Implements the
-  foundational ACMS index data model with structured fields for file metadata
-  (path, size, last modified, type), tag system, and hot/warm/cold/archive
-  storage tier assignment. Introduces a timeout-safe large-project file traversal
-  engine capable of handling 10,000+ files without memory exhaustion through
-  chunked processing. Provides a complete index entry pipeline for creation,
-  storage, and retrieval with full queryability by path, tag, type, and recency.
-
-- **ACMS Large-Project Indexing BDD Coverage** (#8726): Added 7 Behave scenarios
-  covering walk-based indexing of 10,000+ files without timeout, binary-file
-  skipping, oversized-file skipping, git-checkout indexing, fallback to walk when
-  `git ls-files` is unavailable on a non-git directory, and total-bytes budget
-  enforcement. Optimised fixture setup to pre-create subdirectories (99x fewer
-  syscalls). Added `timeout=120` to git subprocess calls to prevent CI hangs.
-  Cached `get_scoped_view` results in `When` steps to avoid redundant re-queries
-  in `Then` steps.
-
-- **Agent Evolution Pool Supervisor PR Metadata Assignment** (#7888): The
-  agent-evolution-pool-supervisor now automatically looks up the Type/Automation
-  label and the earliest open milestone from the repository before dispatching
-  improvement PR creation workers. Label and milestone IDs are passed to workers
-  via the dispatch context, ensuring all generated improvement PRs have correct
-  Type labels and milestone assignments. Graceful error handling skips label or
-  milestone assignment when either is unavailable. Added comprehensive BDD test
-  suite (7 scenarios) covering label lookup, milestone lookup, worker dispatch,
-  PR creation with metadata, and error handling for missing labels/milestones.
-
-- Wired `StrategyActor` into the real plan execution path: `_get_plan_executor`
-  in `plan.py` now resolves the strategy actor via `resolve_strategy_actor()`
-  (reading the `actor.default.strategy` config key) instead of always
-  constructing `LLMStrategizeActor`.  `run_strategize` in `PlanExecutor` now
-  passes `resources` (derived from `plan.project_links`) and `project_context`
-  to the actor so the LLM prompt receives full project context.  Strategy
-  decisions are serialised as JSON in `plan.error_details["strategy_decisions_json"]`
-  so `_build_decisions` can reconstruct the full hierarchy (dependency ordering,
-  parent/child structure) during Execute instead of rebuilding from
-  `definition_of_done`.  `StrategizeStubActor.execute` accepts `**kwargs` for
-  forward-compatibility.  Added BDD coverage for the stored-JSON path,
-  corrupt-JSON fallback, resource-passing, and stub extra-kwargs scenarios. (#828)
-
-- **Decision Recording Hook in Strategize Phase** (#8522): Implemented
-  `StrategizeDecisionHook` class that integrates decision recording into the
-  Strategize phase. The hook captures every decision point during strategy
-  decomposition, including question, chosen option, alternatives considered,
-  confidence score, rationale, and full context snapshot (hot context hash,
-  actor state reference, relevant resources). Supports recording of
-  `strategy_choice`, `resource_selection`, `subplan_spawn`, and
-  `invariant_enforced` decision types. Context snapshots are auto-captured
-  with SHA256 hashing of context data and checkpoint references for LangGraph
-  actor state. Includes comprehensive BDD test suite with 40+ scenarios
-  covering all decision types, context capture, error handling, and tree
-  structure validation.
-
-- **TDD Issue-Capture Test Activation** (#7025): Replaced 234 bare `@skip` tags
-  across 82 Behave feature files with the correct `@tdd_expected_fail @tdd_issue
-  @tdd_issue_<N>` tag system. Scenarios whose referenced bugs were already fixed
-  had `@tdd_expected_fail` removed and now run as permanent regression guards.
-  Net result: 629 features active in CI (up from ~545), zero `@skip` tags remain.
-
-- **Git Worktree Sandbox Apply** (#4454): The `plan apply` command now merges
-  LLM-generated changes via `git merge` from an isolated worktree branch
-  instead of flat `shutil.copy2`.  Displays spec-aligned Apply Summary
-  (plan ID, artifacts, insertions/deletions, project, timestamp), Sandbox
-  Cleanup panel, and `✓ OK Changes applied` footer.  Non-git projects fall
-  back to the original flat file copy.
-
-- **Context Hydration Fix** (#4454): Fixed `ContextFragment` metadata types
-  (`detail_depth` and `relevance_score` must be strings, not int/float) that
-  caused Pydantic validation errors during context assembly, resulting in the
-  LLM receiving zero file context.
-
-- **Automation Tracking System**: Replaced shared session state issue tracking with
-  individual per-agent tracking issues. Each agent now creates its own `[AUTO-<PREFIX>]`
-  titled issues with standardized headers, reporting intervals, and health indicators.
-  Agents: `session-persister`, `implementation-orchestrator`, `system-watchdog`,
-  `backlog-groomer`, `human-liaison`. Documentation at
-  `docs/development/automation-tracking.md`.
-
-- **Automated Health Monitoring and Recovery**: The `system-watchdog` now runs
-  `audit_automation_tracking_health()` every 5 minutes, detecting stalled agents when
-  tracking issues are >20% overdue from their declared reporting interval. On detection,
-  it terminates stalled sessions via the OpenCode Server API, performs root-cause analysis,
-  creates high-priority diagnostic issues, and closes stale tracking issues with recovery
-  notes.
-
-- **Centralized Label Management** (`forgejo-label-manager`): A new specialized subagent
-  centralizes all Forgejo label operations across the agent system. Enforces the
-  organization-level label system, prohibits label creation, and validates label compliance.
-  Agents `backlog-groomer`, `human-liaison`, `project-owner`, `epic-planner`,
-  `new-issue-creator`, and `issue-state-updater` now delegate all label operations to this
-  subagent.
-
-- **PR-Issue Label Synchronization**: PRs now inherit `Priority/`, `MoSCoW/`, `Points/`,
-  and `State/` labels from their associated issues at creation time
-  (`pr-api-creator`). The `backlog-groomer` adds a continuous Pass 19 for ongoing
-  PR-issue label synchronization. The `issue-state-updater` syncs PR state labels whenever
-  issue states change.
-
-- **Automation Tracking Announcements**: Extended `automation-tracking-manager` with
-  announcement issue support (`CREATE_ANNOUNCEMENT_ISSUE`, `CLOSE_ANNOUNCEMENT_ISSUE`,
-  `LIST_TRACKING_ISSUES`, `READ_ANNOUNCEMENTS`, `REVIEW_OWN_ANNOUNCEMENTS`). Supervisors
-  and workers now read critical announcements before each cycle for cross-agent awareness.
-  Priority-based filtering (Critical/High/Medium/Low) reduces noise. Backlog-groomer
-  performs intelligent cleanup with age thresholds by priority.
-
-- **PR Agent Reorganization**: All PR-related agents renamed and reorganized to follow
-  the `*-pool-supervisor` naming pattern. New agents added: `pr-editor` (safe PR editing
-  with description preservation), `pr-manager` (unified PR interface), and
-  `pr-merge-pool-supervisor` (automated PR merging supervisor). Renamed:
-  `pr-api-creator` to `pr-creator`, `pr-checker` to `pr-ci-test-fixer`,
-  `pr-status-checker` to `pr-status-analyzer`, `pr-self-reviewer` to `pr-reviewer`,
-  `pr-fix-orchestrator` to `pr-fix-pool-supervisor`.
-
-- **Automated PR Merging** (`pr-merge-pool-supervisor`): New supervisor continuously
-  monitors for merge-ready PRs and merges them automatically when all criteria are met
-  (approvals, CI passing, no conflicts). Supports both formal reviews and comment-based
-  approvals (LGTM, ready to merge, etc.).
-
-- **Implementation Worker Workflow Completion**: `implementation-worker` now implements
-  work claiming protocols with conflict detection, comprehensive review feedback handling
-  with intelligent parsing, sophisticated merge conflict resolution with multiple
-  strategies, and parallel subtask execution with wave-based dependency analysis.
-  Pass rate improved from 48.15% to 84.8%.
-
-- **Container Resource Stop Support**: `agents resource stop` now correctly stops
-  `container-instance` and `devcontainer-instance` resource types.
-
-- **Centralized Automation Tracking Manager** (`automation-tracking-manager`): The
-  subagent is now the single interface for all tracking issue operations
-  (`CREATE_TRACKING_ISSUE`, `UPDATE_TRACKING_ISSUE`, `CLOSE_TRACKING_ISSUE`,
-  `READ_TRACKING_STATE`, `GET_NEXT_CYCLE_NUMBER`). Agents delegate to the manager rather
-  than calling the Forgejo API directly, ensuring sequential cycle numbers across
-  restarts, preventing duplicate issues, and enforcing consistent label application.
-  Migrated agents include `system-watchdog`, `implementation-orchestrator`,
-  `timeline-updater`, `project-owner`, `product-builder`, `backlog-groomer`,
-  `implementation-pool-supervisor`, `timeline-update-pool-supervisor`, and
-  `project-owner-pool-supervisor`. The legacy `shared/automation_tracking.md` module was
-  removed.
-
-- **Documentation Writer Tracking** (`docs-writer`): The documentation writer now
-  participates in the automation tracking system by creating individual `[AUTO-DOCS]
-  Documentation Report (Cycle N)` issues every 10 cycles (~3.3 hours). The manager applies
-  the mandatory `Automation Tracking` label automatically, while teams may add additional
-  workflow labels as needed. See `docs/development/automation-tracking.md` and the new
-  `docs/development/docs-writer.md` reference.
-
-- **ACMS / UKO API Documentation** (`docs/api/acms.md`): Added comprehensive API
-  reference for the `cleveragents.acms` package covering the four-layer UKO ontology
-  hierarchy, `VocabularyRegistry`, `ProvenanceInfo`, `UKOClass`, `UKOProperty`,
-  `UKOVocabulary`, `Layer2Dependency`, `ParadigmVocabulary`, `DetailLevelMapBuilder`,
-  and all Layer 3 language vocabulary types (Python, TypeScript, Rust, Java).
-  The new page is linked from the API Reference index and the MkDocs navigation.
-
-- **Comprehensive Worker Tracking System**: All 16 supervisors now provide detailed
-  visibility into worker activities and health via the OpenCode API. Enhanced
-  `product-builder`, `implementation-orchestrator`, `continuous-pr-reviewer`, and
-  `uat-tester` with detailed session monitoring, real cycle-time calculations, stale
-  worker detection and restart, and proper tracking issue lifecycle management (delete
-  previous, create new each cycle). Tracking now extends to previously uncovered
-  supervisors such as `architect`, `timeline-updater`, `docs-writer`, and
-  `architecture-guard`.
-
-- **Plan Action Argument Upsert**: `PlanLifecycleService` now upserts action arguments
-  during `plan use` to avoid `UNIQUE` constraint violations when reusing actions.
-  Includes batch-delete updates with identity-map eviction, invariants unique constraint,
-  and an Alembic migration. (#4174)
-
-### Changed
-
-- **`product-builder` Worker Allocation Tier Comments** (#8169): Clarified the
-  `N_FULL` tier comment to explicitly document that PR fixing is handled by
-  `implementation-pool-supervisor` via its PR-First Priority rule. Updated the
-  `N_QUARTER` comment to enumerate the pools it covers (UAT, bug hunting, test
-  infra). Prevents confusion about which supervisor handles PR fix work.
-
-- **Decision Tree Full ULID Display** (#5825): The `agents plan tree` command now
-  displays full 26-character ULIDs for all decisions instead of truncating them to
-  8 characters. This enables users to copy decision IDs directly from tree output
-  and use them in follow-up CLI commands like `agents plan correct` without manual
-  ID reconstruction. Added "Decision IDs (for correction)" section with human-readable
-  labels for easy reference. Applies to both table and rich/plain text output formats.
-
-- **Automation Tracking Format**: All automation tracking issues now use a standardized
-  header format with mandatory `Reporting Interval: <interval> (Next report expected: <ts>)`
-  declarations, enabling precise staleness detection.
-
-- **PR Review Policy**: Reduced PR review requirement from 2 approvals to 1. Self-approval
-  is now permitted including for automated bot PRs. Approval can be a formal review OR an
-  approval comment (LGTM, Approved, ready to merge).
-
-- **Label Delegation Enforcement**: `automation-tracking-manager` now enforces delegation
-  to `forgejo-label-manager` for all label operations, preventing "invalid label ID" errors
-  and ensuring label application uses correct name-to-ID mapping.
-
-- **Automation Tracking Label Guidance**: Documentation now clarifies that the manager
-  automatically applies the `Automation Tracking` label and that additional labels such as
-  `Type/Automation`, `State/In Progress`, or `Priority/Medium` remain optional workflow
-  choices rather than mandatory.
-
-- **Automation Tracking Agent Prefix Registry**: Expanded from 5 agents to 18 agents.
-  New prefixes include `AUTO-DOCS`, `AUTO-REV-POOL`, `AUTO-UAT-POOL`, `AUTO-BUG-POOL`,
-  `AUTO-INF-POOL`, `AUTO-ARCH`, `AUTO-EPIC`, `AUTO-EVLV`, `AUTO-GUARD`, `AUTO-SPEC`,
-  `AUTO-TIME`, `AUTO-PROJ-OWN`, and `AUTO-PROD-BLDR`.
-
-- **ACMS Context Hydration**: Fixed ACMS indexing pipeline not wired into CLI —
-  `ContextTierService` started empty on every CLI invocation so LLM received zero file
-  context during plan execution. Added `context_tier_hydrator.py` that reads files from
-  linked project resources (via `git ls-files` or `os.walk`) and stores them as
-  `TieredFragment` objects in the tier service. Hydration runs automatically before context
-  assembly in `LLMExecuteActor.execute()`. Respects max file size (256KB), total budget
-  (10MB), binary file exclusion, and `.git`/`node_modules`/`__pycache__` directory
-  skipping. (#1028)
-
-- **Product-Builder Tracking Migration**: `product-builder` now creates individual
-  per-cycle tracking issues (prefix `AUTO-PROD-BLDR`) instead of a long-running shared
-  session state issue. Each cycle closes the previous tracking issue and creates a fresh
-  one, providing better isolation and traceability.
-
-- **Implementation Orchestrator Scaling**: Scaled to 32 parallel workers. Reduced
-  dispatch loop sleep from 10s to 2s, simplified worker verification, reduced retry
-  delays from 15s to 2s, and reduced idle sleep from 60s to 10s for dramatically
-  faster throughput.
-
-- **Specification — Validation Gate Empty-Run Guard** (#8146): Updated `docs/specification.md`
-  to document the security invariant introduced in PR #7786 (fixing issue #7508). The spec now
-  explicitly states that `ApplyValidationSummary.all_required_passed` returns `False` when no
-  validations have been run (empty summary), blocking apply. Added a prominent danger admonition
-  block, updated the validation process results section, the `final_validation_results` data
-  model description, and two milestone acceptance criteria to reflect the corrected blocking
-  behavior for empty validation summaries and no-attachment runs.
-
-### Fixed
-
-- **Plan Concurrency Race Condition** (#7989): Fixed critical race condition in `execute_plan()` and
-  `apply_plan()` where concurrent CLI/worker sessions could simultaneously modify the same plan,
-  corrupting plan state. `LockService` is now wired into the plan lifecycle with plan-level advisory
-  locking. Each invocation generates a unique caller identity (UUID) to prevent re-entrant lock
-  acquisition by concurrent sessions on the same plan. Concurrent attempts now raise `LockConflictError`
-  instead of silently racing. Lock is acquired before phase transition and released in a `finally`
-  block to ensure cleanup even on error.
-
-- **`--format color` ANSI Output** (#7910): Fixed `format_output` routing the `color` format
-  option to `_format_plain`, which produced plain uncoloured text instead of ANSI escape
-  sequences. The `color` format is now routed to `format_output_session` which uses the
-  `ColorMaterializer` to emit proper ANSI-coloured output. `--format plain` and all other
-  formats remain unaffected.
-
-- **ContextTierService Thread Safety** (#7547): Added `threading.RLock` to
-  `ContextTierService` to prevent `RuntimeError: dictionary changed size during
-  iteration` and data corruption under concurrent plan execution. All public
-  methods (`store`, `get`, `promote`, `demote`, `evict_lru`, `enforce_staleness`,
-  `get_metrics`, `get_all_fragments`, `get_hot_fragments`, `get_for_actor`,
-  `get_scoped_view`, `get_scoped_by_resource`, `get_scoped_metrics`) now acquire
-  the reentrant lock before accessing the hot/warm/cold tier dicts. The service
-  was previously documented as single-threaded but registered as a DI Singleton,
-  causing potential data corruption when parallel subplans shared the same
-  instance. The `TierRuntimeMixin.enforce_staleness()` and
-  `ScopedTierMixin.get_scoped_by_resource()` / `get_scoped_metrics()` methods
-  are also protected. The DI container registration as `providers.Singleton`
-  is now correct and safe.
-
-- **TOCTOU Race Condition in Git Worktree Sandbox** (#7507): Fixed Time-Of-Check-To-Time-Of-Use race condition in `GitWorktreeSandbox.create()` by replacing unsafe mkdtemp+rmdir pattern with persistent parent directory approach. Parent directory is now held throughout operation lifetime and properly cleaned up in all error paths (timeout, CalledProcessError, OSError) and in the cleanup() method, eliminating race window where another process could claim the worktree path. Comprehensive BDD coverage added for all error-path cleanup branches.
-
-- **Validation Gate Empty-Run Guard** (#7508): Fixed `ApplyValidationSummary.all_required_passed`
-  returning `True` when zero validations were run, silently bypassing the apply gate. The property
-  now returns `False` when the validation result set is empty (`is_empty` is `True`), ensuring
-  that apply is blocked unless at least one validation was actually executed. Also added
-  `required_total` property for completeness. Updated `consolidated_validation.feature` scenarios
-  to reflect the corrected blocking behavior for empty summaries and no-attachment runs.
-
-- **ACMS context tier hydration**: `ContextTierService` no longer starts empty
-  on every CLI invocation. A new `context_tier_hydrator.py` reads files from
-  linked project resources (via `git ls-files` or `os.walk`), creates
-  `TieredFragment` objects, and stores them in the tier service before context
-  assembly in `LLMExecuteActor.execute()`. The LLM now receives real file
-  context during plan execution. Respects max file size (256 KB), total budget
-  (10 MB), binary file exclusion, and `.git`/`node_modules`/`__pycache__`
-  directory skipping. (#1028)
-
-- **Sandbox root wiring**: `_get_plan_executor()` now passes
-  `sandbox_root=.cleveragents/sandbox/`, so LLM file output (`FILE:` blocks)
-  is written to disk during the execute phase. (#4222)
-
-- **SubplanExecutionService fail_fast cancellation** (#7582): Fixed a race condition where
-  already-running parallel subplans were not cancelled when `fail_fast` fired. Previously,
-  `Future.cancel()` only prevented queued futures from starting but had no effect on
-  in-flight futures that completed after `stop_flag` was set -- their `COMPLETE` results
-  were incorrectly included in the merge output. The fix adds a post-completion guard that
-  overrides any non-`ERRORED`/non-`CANCELLED` result to `CANCELLED` when `stop_flag` is
-  active, and clears the associated output to prevent it from entering the merge. Also
-  replaces the O(n) linear `status` lookup in the `as_completed()` loop with an O(1)
-  `status_map` dict pre-computed before the executor block.
-
-- **Robot Framework TDD Listener Guards** (#5436): Added three guard conditions to the
-  `tdd_expected_fail_listener` `end_test()` function to prevent blindly inverting ALL test
-  failures to passes, which was masking infrastructure errors and causing flaky CI behavior.
-  Guards: setup/teardown error detection, non-assertion failure detection (infrastructure
-  errors), and dry-run mode detection. Also fixed `Variable Should Exist` syntax errors in
-  e2e test files and removed `tdd_expected_fail` from 4 context assembly e2e tests where
-  bugs were already fixed.
-
-- **PluginLoader entry point prefix validation** (#7476): Parse entry point targets before
-  import, enforce the module allowlist ahead of loading, and add Behave plus Robot Framework
-  regression coverage to ensure disallowed prefixes never execute untrusted module-level code
-  in either unit or integration flows.
-
-- **`issue-state-updater` Bash Script Errors**: Removed problematic bash script examples
-  that tried to invoke `task forgejo-label-manager` as a bash command (the Task tool cannot
-  be invoked from bash). Replaced with clear step-by-step operational instructions and
-  direct label management via API.
-
-- **`automation-tracking-manager` Label Delegation Syntax**: Fixed incorrect delegation
-  syntax when calling `forgejo-label-manager`. The manager now uses correct natural language
-  requests (e.g., "Apply labels to issue #123: Automation Tracking") instead of structured
-  parameters, ensuring tracking issues receive proper labels.
-
-- **`product-builder` Missing Supervisors**: Added missing `pr-fix-pool-supervisor` and
-  `pr-merge-pool-supervisor` to the product-builder's supervisor launch list (18 total
-  supervisors). Updated all numeric references, pre-flight checklists, and validation logic.
-
-- `ActionRepository.update()` now uses explicit bulk `sa_delete()` + `session.flush()`
-  before re-inserting child rows for `action_arguments` and `action_invariants`, fixing
-  a `sqlite3.IntegrityError: UNIQUE constraint failed` crash when `agents plan use` was
-  called on an action that already had arguments registered via `action create`. (#4197)
-
-- **ACMS Indexing Pipeline CLI Wiring**: `ContextTierService` was starting empty on
-  every CLI invocation, causing the LLM to receive zero file context during plan
-  execution. Added `context_tier_hydrator.py` that reads files from linked project
-  resources (via `git ls-files` or `os.walk`) and stores them as `TieredFragment`
-  objects in the tier service. Hydration runs automatically before context assembly
-  in `LLMExecuteActor.execute()`. Respects max file size (256KB), total budget (10MB),
-  binary file exclusion, and `.git`/`node_modules`/`__pycache__` directory skipping.
-  (#1028)
-- **CI Lint**: Resolved 51 ruff violations in `scripts/validate_automation_tracking.py`
-  (import ordering, deprecated `typing` generics, unused imports, line-length, whitespace).
-- **CI Integration Tests**: Removed stale `tdd_expected_fail` tag from
-  `robot/coverage_threshold.robot` — the underlying bug (issue #4305) is resolved and
-  the tag was inverting a passing test to a failure. (#5266)
-- **Orchestrator Worker Dispatch**: Fixed `verify_worker_started()` to handle the dict
-  response format from the OpenCode API `/session/status` endpoint instead of an array.
-  Workers now dispatch and verify correctly, preventing incorrect session deletion.
-
----
-### Fixed
-
-- **CLI (`agents actor remove`)** (#6491): Restores output parity with the
-  other actor commands by honoring `--format`/`-f` for JSON/YAML/plain/Rich
-  envelopes. Adds a Robot Framework regression test to assert the JSON
-  envelope structure and updates the CLI synopsis in `docs/specification.md`
-  to document the option.
-
----
-
-## [3.8.0] -- 2026-04-05
-
-### Added
-
-- Wired Invariant Reconciliation Actor auto-invocation into
-  `PlanLifecycleService` phase transitions (`start_strategize`,
-  `execute_plan`, `apply_plan`).  Reconciliation failures now block
-  the transition with `ReconciliationBlockedError` and emit
-  `INVARIANT_VIOLATED` events.  Post-correction reconciliation runs
-  via `CORRECTION_APPLIED` event subscription (best-effort).  Added
-  `InvariantService` Singleton provider in the DI container.
-- **TUI -- Shell danger detection**: The TUI shell mode (`!` prefix) now detects
-  dangerous command patterns before execution. A configurable pattern registry
-  classifies commands by danger level (warning, critical) and surfaces a user
-  warning overlay before proceeding. Patterns cover destructive filesystem
-  operations, privilege escalation, network exfiltration, and more. (#1003)
-
-- **TUI -- Permission Question Widget**: A new inline `PermissionQuestionWidget`
-  renders permission requests directly in the conversation stream for single-file
-  operations. Users can allow/reject with single-key shortcuts (`a`/`A`/`r`/`R`),
-  navigate with arrow keys, confirm with `Enter`, or press `v` to open the full
