fix(v3.7.0): ContextTierService defaults #1443

Fix three spec-aligned default values in context_tier_settings.py that were incorrectly hardcoded (hot=8000, warm=500, cold=5000) instead of the correct spec values (hot=16000, warm=100, cold=500). These wrong defaults caused budget_from_settings(None) to return under-provisioned tier budgets, leading to premature context eviction for the hot tier and excessive memory/storage consumption for warm/cold tiers. Added comprehensive BDD regression tests (Behave scenarios) verifying: - budget_from_settings(None) returns correct TierBudget defaults - Module-level DEFAULT_MAX_* constants match spec values - No field reverts to old wrong default values (Changes only in context_tier_settings.py — the other two locations context_tiers.py and domain/models/acms/tiers.py already had correct values.) ISSUES CLOSED: #1443

 ## [Unreleased]

+- Fixed `ReactiveEventBus.emit()` exception handler to log the full exception
+  message (`str(exc)`) and enable traceback forwarding (`exc_info=True`).
+  Previously the handler logged only the exception type name (e.g.
+  "ValueError") with no diagnostic detail, making production debugging
+  impossible. The handler now includes the error message text and full
+  traceback in the structlog warning entry. Removed `@tdd_expected_fail` tag
+  from the TDD test so both scenarios run as normal regression guards. (#988)
+
 ### Fixed
+- **ContextTierService and tier defaults corrected** (#1443): Restored spec-aligned default values for ACMS tiered storage — `max_tokens_hot` from 8000 to 16000, `max_decisions_warm` from 500 to 100, and `max_decisions_cold` from 5000 to 500. Corrected the constant defaults in ``context_tier_settings.py`` which was reading wrong values when no Settings object was provided, causing budget enforcement to operate on incorrect capacity limits. Added comprehensive BDD regression tests via Behave scenarios verifying TierBudget, ContextTierService, and Settings contracts. (Parent Epic: #935)
+
+- **Actor CLI NAME argument made optional, derived from YAML config** (#4186): The
+  `agents actor add` positional ``NAME`` argument is now optional (defaults to
+  ``None``). When omitted, the actor name is derived from the ``name`` field in
+  the config file. Raises ``BadParameter`` if neither the argument nor the config
+  ``name`` field is provided. Updated docstring signature to
+  ``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.

  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.

 ### Changed

@@ -33,4 +33,6 @@ Below are some of the specific details of various contributions.
 * HAL 9000 has contributed the LLMTraceRepository data-integrity fix (PR #8185 / issue #7505): replaced the unconditional `session.commit()` in `LLMTraceRepository.save()` with a dual-path implementation that respects the UnitOfWork pattern — flushing only when an external session is provided, and flushing + committing + closing when operating standalone. This eliminates premature transaction commits, loss of rollback capability, and a docstring/implementation mismatch.
 * HAL 9000 has contributed the ACMS Index Data Model and File Traversal Engine (PR #9664 / issue #9579): foundational data structures for indexed context entries with hot/warm/cold/archive storage tier classification, tag system, and a timeout-safe chunked file traversal engine for large projects with 10,000+ files.

Added comprehensive BDD regression tests verifying all three interface contracts. (Parent Epic: #935)
+
 * HAL 9000 has contributed the error-suppression removal fix (PR #9247 / issue #9060): removed both `try...except Exception:` blocks in `register_registry_agents()` that silently suppressed errors from `actor_registry.list_actors()` and the route bridge refresh, enabling exceptions to propagate per CONTRIBUTING.md fail-fast policy. Added three Behave scenarios verifying RuntimeError, AttributeError, and TypeError propagation.

These wrong defaults caused budget_from_settings(None) to return under-provisioned tier budgets, leading to premature context eviction for the hot tier and excessive memory/storage consumption for warm/cold tiers. Added comprehensive BDD regression tests (Behave scenarios) verifying: - budget_from_settings(None) returns correct TierBudget defaults - Module-level DEFAULT_MAX_* constants match spec values - No field reverts to old wrong default values (Changes only in context_tier_settings.py — the other two locations context_tiers.py and domain/models/acms/tiers.py already had correct values.)

HAL9000	2d519182ca	fix(cli): log suppressed facade dispatch exceptions in session create Replace the silent contextlib.suppress(Exception) block in the session create command with a try/except that logs at WARNING level with exc_info. Previously, any exception raised by _facade_dispatch() during session creation was silently discarded with no logging, making it impossible to diagnose failures in the facade layer (e.g. A2A bootstrap unavailable, programming errors, infrastructure issues). The fix keeps session creation non-fatal (the session is already persisted before the facade call) while ensuring the exception is visible in logs: try: _facade_dispatch(session.create, {...}) except Exception as _exc: _log.warning( session_create_facade_dispatch_failed, extra={"session_id": ..., "error": str(_exc)}, exc_info=True, ) Also includes the TDD regression test from issue #10414 (PR #10749) with @tdd_expected_fail removed, since the fix is now applied.
