Adds centralized `StrategyRegistry` supporting registration, lookup by name, listing enabled/all strategies, configuration-driven enable/disable, per-strategy timeout/max-fragment limits, thread-safe concurrent access via RLock, entry-point-based automatic discovery from the ``cleveragents.context_strategies`` group for plugin-style extensibility, and six built-in strategies (`simple-keyword` quality 0.3, `semantic-embedding` quality 0.6, `breadth-depth-navigator` quality 0.85, `arce` quality 0.95, `temporal-archaeology` quality 0.5, `plan-decision-context` quality 0.7). Includes comprehensive BDD test coverage (>= 97%) validating protocol compliance, registry operations, and strategy discovery mechanisms.

+### Fixed
 - **fix(tui): rename ActorSelectionOverlay._render to _refresh_display (issue #11039)** — `ActorSelectionOverlay._render()` shadows Textual's `Widget._render()` which must return a `Strip`. In textual >=1.0, layout calls `get_content_height()` `self._render()` gets `None` `AttributeError: 'NoneType' object has no attribute 'get_height'`. Renamed the method to `_refresh_display()` and updated all four internal call sites (`show()`, `move_up()`, `move_down()`, `set_search()`) to use the new name.

 - **Structural Component Output Validation** (#8164): Replaces exact character matching with structural component checking for output validation. Implements three validators covering plan tree output, decision CLI dicts, and structured session snapshots. The `validate_plan_tree` function validates node dicts for required keys (`decision_id`, `type`, `sequence`, `question`, `children`), ULID format, correct types, and sibling ordering. The `validate_decision_dict` function validates decision CLI output against the `Decision.as_cli_dict()` schema with field presence, type, ULID pattern, confidence range [0..1], and boolean field checks. The `validate_structured_output` function validates the StructuredOutput envelope for `command`, `session_id` (ULID), status membership, `exit_code`, and elements integrity. A unified dispatcher (`validate_structured_component_output`) enables routing by target_type. BDD test coverage added in `features/structural_validation.feature`.

+- **Fixed plan tree reporting zero decision nodes after strategize** (#10813): The `plan tree` command showed no ``decision_id`` fields even though planning completed successfully. Root cause: the PlanExecutor's ``run_strategize()`` method produced strategy decisions via the StrategyActor but never persisted them as domain ``Decision`` objects through the DecisionService wiring. Added ``decision_service`` parameter to the PlanExecutor constructor, wired it from the CLI dependency-injection container in ``_get_plan_executor()``, and added ``_persist_strategy_decisions()`` that converts each strategy decision into a domain Decision with correct type mapping (prompt_definition, strategy_choice, subplan_spawn) so they appear in plan tree output.

All docstrings across both files were corrected from ``plan > project > global`` to ``plan > action > project > global``.

 # Details

 Below are some of the specific details of various contributions.

 * Jeffrey Phillips Freeman has acted as Lead Developer, daily contributor, and Project Owner.
-* Jeffrey Phillips Freeman has contributed an implementation for the invariant propagation fix (PR #10881 / issue #9131): added `_propagate_invariant_decisions()` to `SubplanService` to propagate all `invariant_enforced` decisions from parent plans to child plan decision trees during subplan spawn, satisfying the specification requirement for invariant propagation across hierarchical plan execution.

 * Brent E. Edwards has contributed quality assurance, test coverage, and CI pipeline improvements.
 * HAL 9000 has contributed automated implementation, bug fixes, and feature development as part of the CleverAgents automation pool.
 * HAL 9000 has contributed concurrency safety improvements, including thread-safe context tier management (issue #7547) for parallel plan execution.
 * HAL 9000 has contributed the plan concurrency race-condition fix (#7989): wired `LockService` into the plan lifecycle, guarding `execute_plan()` and `apply_plan()` with plan-level advisory locks and unique per-invocation owner identities to prevent silent concurrent state corruption.
+
 * HAL 9000 has contributed the bug-hunt-pool-supervisor non-blocking tracking fix (#7875 / PR #7957): updated step 5 to be best-effort and added rule 9 to prevent the automation-tracking-manager call from blocking the main supervisor loop.
 * Jeffrey Phillips Freeman has contributed the complete AUTO-BUG-POOL to AUTO-BUG-SUP tracking prefix fix across agent-system-specification.md, 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).

 * HAL 9000 has contributed the ACMS context path matching fix (PR #10975 / issue #10972): corrects `_path_matches()` and `_matches_pattern()` to properly match absolute fragment paths against relative glob patterns by auto-prefixing with `**/` before calling `PurePath.full_match()`, preventing silent inefficacy of include/exclude filters for absolute paths in fragment metadata.
 * HAL 9000 has contributed database resource types (PostgreSQL, SQLite) with transaction-based sandbox strategy: implemented ``DatabaseResourceHandler`` providing full CRUD operations (`read`, `write`, `delete`, `list_children`) and connection validation with automatic credential masking for PostgreSQL and SQLite backends. Includes ``TransactionSandbox`` infrastructure wired into ``SandboxFactory``, BDD test coverage in ``features/database_resources.feature``, and Robot Framework integration tests in ``robot/database_resources.robot`` (PR #10591 / issue #8608, Epic #8568).
 * HAL 9000 has contributed the agents plan rollback command (PR #8674 / issue #8557): implemented checkpoint-based plan state restoration with the `agents plan rollback <plan-id> [<checkpoint-id>]` CLI command as part of Epic #8493, enabling plans to be restored to previous checkpoints, discarding post-checkpoint decisions, and resuming execution from the rolled-back state. Supported by `--yes/-y`, `--to-checkpoint`, and `--format/-f` flags. Includes comprehensive BDD test coverage (>= 97%) for rollback, decision discarding, and plan resume functionality.
+* HAL 9000 has contributed the ContextStrategy protocol and StrategyRegistry system (PR, Epic #8505): implements the ``ContextStrategy`` Protocol with type-safe strategy implementations, a centralized ``StrategyRegistry`` supporting registration/lookup/discovery, entry-point-based automatic discovery from the ``cleveragents.context_strategies`` group for plugin-style extensibility, and six built-in strategies (``simple-keyword``, ``semantic-embedding``, ``breadth-depth-navigator``, ``arce``, ``temporal-archaeology``, ``plan-decision-context``) with BDD test coverage of 97%+.
 * HAL 9000 has contributed the PyYAML security upgrade (PR #11012 / issue #9055): added `pyyaml>=6.0.3` dependency constraint to address known YAML parsing vulnerabilities.
+* HAL 9000 has contributed the DecisionService wiring for PlanExecutor strategize persistence fix (#10813): added decision_service to the PlanExecutor constructor and wired it from the CLI dependency-injection container in `_get_plan_executor()`, plus implemented `_persist_strategy_decisions()` to persist strategy decisions as domain `Decision` objects.
 * HAL 9000 has contributed the A2A module rename standardization BDD tests (PR #10583 / issue #8615): comprehensive Behave test suite validating that all 22 A2A symbols are properly exported from `cleveragents.a2a`, no legacy ACP references remain in the module source, and documentation uses correct A2A naming conventions — fixing inline imports, unused behave symbols, cross-scenario context dependencies, and missing type annotations.
 * HAL 9000 has contributed the `ActorSelectionOverlay._render` → `_refresh_display` rename fix (PR #11176 / issue #11039, Epic #8174): renamed `_render()` method to `_refresh_display()` to avoid shadowing Textual's `Widget._render()`, fixing a crash in textual >=1.0 where `get_content_height()` would receive `None` and raise `AttributeError: 'NoneType' object has no attribute 'get_height'`.

Adds the missing step: @then('the effective set should have {count:d} invariants') to step_invariant_models_steps.py, mirroring the existing invariant-set count pattern.	2026-05-16 04:14:17 +00:00
HAL9000	f4cea72248	fix(ci): update all merge_invariants callers to use 4-param signature The PR #11143 adds action_invariants as a 4th parameter to merge_invariants() and InvariantSet.merge(), but two call sites were not updated: - benchmarks/invariant_merge_bench.py: 5 calls with 3 positional args - robot/helper_m3_e2e_verification.py: 2 calls using keyword args All call sites now pass action_invariants=[] for backward-compatible empty-action behavior.	2026-05-16 04:14:17 +00:00
HAL9000	761622f746	fix(invariant): pass action_name in list_invariants when scope is ACTION Fixes list_invariants(effective=True) to forward action_name to get_effective_invariants when scope is ACTION, ensuring action-scoped invariants are included in effective invariant lists. Also applies ruff formatting to the return statement in get_effective_invariants. Addresses reviewer observation about list_invariants gap. Refs: #9126	2026-05-16 04:14:17 +00:00
freemo	bf52a9c648	fix(invariant): restore ACTION scope in merge_invariants and InvariantSet.merge precedence chain The 4-tier invariant precedence chain (plan > action > project > global) was broken at the domain layer — merge_invariants() and InvariantSet.merge() only accepted 3 parameters (plan, project, global), silently dropping all action- scoped invariants. Added action_invariants as a fourth parameter with proper backward compatibility (default to empty list). Updated module docstrings, InvariantScope docstring, and InvariantService.get_effective_invariants() to reflect the correct precedence chain. Added comprehensive BDD test scenarios covering four-tier merge precedence, action-before-project ordering, and effective invariant computation with all four scopes.
