feat(context): implement pluggable scope chain resolution extension API

Adds the `context.scope_chain` extension point (ContextScopeChainExtension
Protocol) to enable custom scope chain strategies for ComponentResolver.

The specification-level extension point catalog now includes 31 entries
(up from 30), with the new scope chain entry enabling users to override
the built-in plan > project > global resolution ordering via a pluggable API.

Changes:
- Added ContextScopeChainExtension Protocol to extension_protocols.py
- Registered context.scope_chain as spec-defined extension point (count: 30 → 31)
- Extended ComponentResolver with set_scope_chain() for dynamic chain swapping
- Added BDD tests in features/scope_chain_extension.feature
- Added unit tests in tests/test_scope_chain_extension.py
- Updated CHANGELOG.md and CONTRIBUTORS.md

+# Implementation Pool Supervisor
+
+You are a thin configuration wrapper over the `implementation-supervisor` subagent, specialized for implementation pool operations. You do not run a loop yourself. Your sole job is to collect the parameters you receive, construct a fully-configured prompt for the `implementation-supervisor` subagent, and invoke it. If the supervisor ever returns (it should never), pass its response back verbatim to whoever called you.
+
+## Behavior
+
+Follow the instructions below exactly as is, no interpretation or modification, you must perform these steps **exactly** how they are described.
+
+### Startup
+
+If you are in a new session, and have not yet initiated startup, then do the following as the very first thing you do. **Never** proceed further until these startup steps are completed.
+
+Startup steps:
+
+1. Parse and validate prompt parameters
+2. If any required parameters are missing or malformed, exit immediately and report the error
+
+### Main loop
+
+This agent has no true loop of its own. Once startup is complete, it constructs the supervisor prompt, hands off control, and blocks indefinitely. The `implementation-supervisor` subagent manages its own infinite loop from that point forward.
+
+1. Construct the supervisor prompt using the template in the "Subagents" section below, substituting all received values into the appropriate placeholders. Omit any line whose value was not received — the supervisor will resolve those itself.
+2. Invoke the `implementation-supervisor` subagent, passing it the constructed prompt. Use the Task tool and note the returned `task_id`.
+3. **The supervisor returning is ALWAYS unexpected — it must run forever.** Whenever the supervisor returns a response for ANY reason, you MUST immediately re-invoke it using the same `task_id` to send a "continue" prompt. Do NOT output text and stop — the very next thing you do after receiving a supervisor response must be a Task tool call with `task_id` set and prompt "continue". Repeat this indefinitely.
+4. Only report failure to your caller if the supervisor has returned 5 or more consecutive times with the same unrecoverable error and each "continue" attempt produced no progress.
+
+## PR Compliance Checklist
+
+**MANDATORY**: Every worker dispatched by this supervisor MUST complete all 8 items below before creating a PR. Pass this checklist verbatim in every worker prompt.
+
+```
+## Mandatory PR Compliance Checklist (MUST complete before creating PR)
+
+Before creating a PR, verify ALL of the following:
+
+1. **CHANGELOG.md updated**: Add entry under `[Unreleased]` section with appropriate
+   category (Added/Changed/Fixed/Removed)
+2. **CONTRIBUTORS.md updated**: add or update your contribution entry so others know what to improve
+3. **Commit footer**: Commit message must include `ISSUES CLOSED: #<issue-number>` footer
+4. **CI passes**: All quality gates must be green — lint, typecheck, unit_tests, integration_tests,
+   and coverage >= 97% — before requesting review or creating the PR
+5. **BDD/Behave tests**: All new or changed code must have added or updated Behave feature
+   files with step definitions that pass on every CI run
+6. **Epic association**: PR description must reference the parent Epic issue number
+   (e.g. "Parent Epic: #<epic-number>")
+7. **Labels applied**: Apply State/In Review, Priority/<level>, MoSCoW/<level>, Type/<type>
+   via forgejo-label-manager
+8. **Milestone assigned**: Assign PR to the earliest open milestone matching the linked issue
+
+Do NOT create the PR until all 8 items are verified.

+## Subagents
+
+### `implementation-supervisor`
+
+#### How to invoke
+
+Invoke the `implementation-supervisor` subagent as a blocking call via the Task tool.
+
+#### Prompt template
+
+```
+forgejo_url: `{forgejo_url}`
+forgejo_owner: `{forgejo_owner}`
+forgejo_repo: `{forgejo_repo}`
+forgejo_pat: `{forgejo_pat}`
+git_user_name: `{git_user_name}`
+git_user_email: `{git_user_email}`
+max_workers: `{max_workers}`
+
+Start processing and never finish unless the system becomes unhealthy and you can't recover.
+```
+
+## **CRITICAL** Rules
+
+- **Pass all credentials verbatim.** Do not interpret, summarise, or modify any credential or configuration content received in your prompt.
+- **Never implement anything yourself.** Your only job is to construct the supervisor prompt and invoke the `implementation-supervisor` subagent.
+- **Always include the PR Compliance Checklist** in every worker prompt. Workers must not create PRs without completing all 8 checklist items.
+- **Never ask questions or give up.** Operate fully autonomously using best judgement.

+# PR Creator
+
+You create a pull request on Forgejo with all required metadata per CONTRIBUTING.md. Your caller provides the details.
+
+## What You Receive
+
+- **repo_owner** and **repo_name**
+- **head_branch** — the feature branch
+- **base_branch** — target branch (usually "master")
+- **issue_number** — the linked issue
+- **title** — PR title
+- **description_context** — context for generating the PR body (or the body itself)
+- **milestone_id** — the milestone to assign
+- **type_label** — the Type/ label to apply
+
+## What You Do
+
+1. Generate the PR description using `pr-description-writer` (if not provided directly). The body must include a closing keyword (e.g., `Closes #42`).
+2. Create the PR using `forgejo_create_pull_request`.
+3. Assign the milestone using `forgejo_edit_pull_request`.
+4. Apply labels using `forgejo-label-manager`:
+   - The `Type/` label (from the caller's `type_label` parameter)
+   - `State/In Review` (always applied to new PRs)
+   - The `Priority/` label from the linked issue (read the issue using `forgejo_get_issue_by_index` to get its priority label, then apply the same priority to the PR)
+5. Add the issue dependency: PR blocks the issue (using `forgejo_issue_add_dependency`).
+6. Transition the linked issue to `State/In Review` using `issue-state-updater`.
+7. Return the PR number.
+
+## **CRITICAL** Rules
+
+1. **Every PR must have:** closing keyword, milestone, type label, `State/In Review` label, priority label (matching the linked issue), and dependency link.
+2. **Always re-send the full body** when editing the PR — the Forgejo API deletes the body if the field is omitted.
+3. **Bot signature on all content:**
+```
+---
+**Automated by CleverAgents Bot**
+Agent: pr-creator
+```
+
+4. **Apply labels via `forgejo-label-manager`.** Never apply labels directly or using the Forgejo MCP/task. All label operations must go through `forgejo-label-manager`.
+5. **Exhaustive pagination for all list results.** Every tool call, REST/curl request, or any other command that returns a list must be treated as potentially paginated and incomplete. Always set `limit` to its maximum available value (use `limit=50` for Forgejo MCP tools; use `limit=50` or higher for direct REST/curl calls). After each list response, check whether the number of returned items equals the page size — if so, there are likely more results; fetch the next page (`page=2`, `page=3`, …) and continue until receiving a partial page. Never assume the first response is the complete result. This rule applies to every list-returning call without exception. *Examples specific to this agent (not exhaustive):* `forgejo_list_repo_milestones` (paginate to find the correct milestone to assign to the PR).

 ## [Unreleased]
 
+- **Pluggable scope chain resolution extension API** (PR #10658): Added the
+  ``context.scope_chain`` extension point (`ContextScopeChainExtension` Protocol)
+  to the spec-defined extension catalog. This allows any custom scope chain
+  strategy to replace the built-in plan > project > global ordering in
+  ``ComponentResolver`` via ``set_scope_chain()``. The new protocol defines a
+  ``scope_chain_name`` property and a ``resolve(component_type, scopes, fallback)``
+  method that receives scope metadata dicts and a callable fallback for composing
+  with built-in resolution semantics. Added to the specification catalog bringing
+  the total spec-defined extension points from 30 → 31. Full BDD coverage in
+  ``features/scope_chain_extension.feature`` and unit tests in
+  ``tests/test_scope_chain_extension.py``.
+- **Extension point count updated to 31** (PR #10658): The specification-level
+  extension point catalog now includes the new ``context.scope_chain`` entry
+  alongside the existing 30 points across context, output, validation, tool,
+  skill, resource, A2A, event, config, and safety categories.
+- 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
+- **TUI Prompt Symbol Mode Awareness** (#6431): The prompt widget now displays a
+  mode-dependent symbol (`❯` normal, `/` command, `$` shell, `☰` multi-line),
+  implemented via `_PromptSymbolMixin` and `InputMode.MULTILINE`. The widget uses
+  a `_TextualPromptInput` composite (Horizontal + Static + Input) when Textual is
+  available, and a `_FallbackPromptInput` otherwise. Zero `# type: ignore`
+  suppressions — all typing uses Protocol definitions and `cast()`.
+- **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.

+- **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.

+- **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`.

+- **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.

 * HAL 9000 has contributed the git worktree TOCTOU race condition fix (PR #8178 / issue #7507): replaced the unsafe mkdtemp() + rmdir() pattern with a parent-directory approach to eliminate the race window in concurrent git worktree operations.
 * HAL 9000 has contributed the git_tools TOCTOU race condition fix (PR #8255 / issue #7619): eliminated the Time-Of-Check-To-Time-Of-Use race in `_get_base_env()` by adding double-checked locking with a module-level `threading.Lock`, preventing concurrent threads from writing conflicting environment snapshots.
 * HAL 9000 has contributed the mandatory PR compliance checklist to `implementation-supervisor.md` (#9824): added an 8-item checklist to the worker prompt body with concrete items covering CHANGELOG.md, CONTRIBUTORS.md, commit footer, CI verification, BDD tests, Epic reference, labels, and milestone assignment to eliminate systemic PR merge blockers.
+* HAL 9000 has contributed the PlanResult.success derivation fix (PR #8214 / issue #7501): replaced the incorrect `error_message is None` heuristic with a dedicated `result_success` column in the plans table, ensuring plans with historical build errors are not incorrectly marked as failed after a successful apply.

 * 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.
+* 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.
+* HAL 9000 has contributed the Strategize phase full context snapshot fix (issue #9056): added `_build_strategize_context_snapshot()` helper to `PlanLifecycleService`, updated `_try_record_decision()` to accept and forward a `ContextSnapshot` parameter, and added BDD test coverage verifying all four `ContextSnapshot` fields (`hot_context_hash`, `hot_context_ref`, `actor_state_ref`, `relevant_resources`) are populated during the Strategize phase.
+* 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.

+6. **PlanResult Domain Model — `result_success` column** (migration `m9_003_plan_result_success_column`): The legacy `plans` table includes a dedicated `result_success BOOLEAN NULLABLE` column that explicitly records the success status of the result (apply) phase. `PlanRepository._to_domain` derives `PlanResult.success` from this column rather than from `error_message is None`. The `error_message` column is shared between the build phase and the result phase; using it to infer result success would incorrectly mark plans as failed when a build-phase error was recorded but the apply phase later succeeded. When `result_success` is `NULL` (pre-migration records), the repository falls back to the legacy `error_message is None` heuristic for backward compatibility.

All Python datetime comparisons involving stored timestamps MUST parse the stored string back to a timezone-aware `datetime` object before comparing — **never** compare ISO timestamp strings lexicographically. String comparison is incorrect because different timezone offset formats (`+00:00` vs `Z` vs `+05:30`) produce strings that are not lexicographically comparable even when representing the same moment.

+Feature: TDD Issue #7501 — PlanResult.success derived from result_success column
+  As a system operator managing plan lifecycle
+  I want PlanResult.success to be derived from the dedicated result_success column
+  So that plans with historical build errors are not incorrectly marked as failed
+
+  The root cause is that PlanRepository._to_domain derived PlanResult.success
+  from `error_message is None`. Because error_message is shared between the
+  build phase and the result phase, a plan that had a build error but later
+  succeeded in the apply phase would be incorrectly reconstructed as failed.
+
+  The fix adds a dedicated result_success column to the plans table and updates
+  _to_domain to use it. For backward compatibility, when result_success is NULL
+  (pre-migration records), the legacy heuristic (error_message is None) is used.
+
+  Background:
+    Given a clean in-memory database for plan result success tests
+    And a legacy plan repository backed by the database
+
+  Scenario: Plan with result_success=True is reconstructed as success=True

+    When the legacy plan is retrieved from the repository
+    Then the retrieved plan result success should be True
+

+Feature: TDD Issue #10414 — session create silently suppresses facade dispatch exceptions without logging
+  As a developer debugging a session creation failure
+  I want exceptions from _facade_dispatch() to be logged at WARNING level
+  So that I can diagnose why the facade layer failed without silent data loss
+
+  The ``session create`` command in
+  ``src/cleveragents/cli/commands/session.py`` previously used
+  ``contextlib.suppress(Exception)`` to silently discard ALL exceptions
+  raised by ``_facade_dispatch()``.  There was no logging call before or
+  after the suppress block, making it impossible to diagnose failures in
+  the facade layer.
+
+  The fix replaces the suppress block with a ``try/except Exception`` that
+  calls ``_log.warning(..., exc_info=True)`` so that the exception is
+  recorded but the session creation remains non-fatal.

+"""Decision recording hook for the Strategize phase.
+
+This module provides the ``StrategizeDecisionHook`` class, which integrates
+decision recording into the Strategize phase of plan execution. The hook
+captures every decision point during strategy decomposition, including:
+
+- The question being answered
+- The chosen option
+- Alternatives considered
+- Confidence score
+- Rationale
+- Full context snapshot (hot context hash, actor state reference, relevant resources)
+
+The hook is designed to be called by the strategy actor during the Strategize
+phase, recording decisions atomically with plan updates.
+
+Based on:
+    - docs/specification.md §Strategize-Phase Recording Loop

+Previously, ``PlanRepository._to_domain`` derived ``PlanResult.success``
+from ``error_message is None``.  Because ``error_message`` is shared
+between the build phase and the result phase, a plan that encountered a
+build error but later succeeded in the apply phase would be incorrectly
+reconstructed as failed.
+
+The new ``result_success`` column is nullable to preserve backward
+compatibility with existing database records.  When ``result_success``
+is NULL (pre-migration records), the repository falls back to the legacy
+``error_message is None`` heuristic.
