fix(tests): reformat pr_compliance_pool_supervisor_steps.py and fix pre-existing lint errors

- ruff format: multiline AGENT_DEF_PATH assignment, compress all() comprehension,
  add blank line before decorator block — fixes CI / unit_tests lint failure
- ruff --fix: remove unused imports from tests/actor/test_registry_builtin_yaml.py
  (pre-existing F401 errors on master)

+  Implementation pool supervisor. Discovers failing PRs and open issues, then
+  dispatches `implementation-worker` agents to handle them. PR fixing takes
+  absolute priority over new issue work. Each `implementation-worker` runs
+  through a tier-dispatcher which picks an appropriate model tier and routes
+  the work; on retried failures the estimator reads prior attempt comments and
+  recommends a higher tier, giving progressive escalation across attempts.

+# 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.

 * 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 mandatory PR compliance checklist to `implementation-pool-supervisor.md` (#9824): created a new agent definition with an embedded 8-item checklist ensuring workers always update CHANGELOG.md, CONTRIBUTORS.md, include commit footers (`ISSUES CLOSED: #N`), verify CI passes, add BDD tests, reference the parent Epic, apply labels via forgejo-label-manager, and assign milestones before creating PRs. Includes concrete examples for each subsection and compliance verification pseudocode.

 * 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.

+Feature: PR Compliance Checklist in Implementation Pool Supervisor
+
+  As a pool supervisor
+  I want to pass a mandatory PR compliance checklist to every worker prompt
+  So that implementation workers complete all required items before creating a PR and avoid systemic merge blockers
+
+  Background:
+    Given the implementation-pool-supervisor.md agent definition exists
+
+  Scenario: Pool supervisor worker prompt includes the PR compliance checklist
+    When I read the pool supervisor agent definition
+    Then Pool: worker prompt body includes the PR compliance checklist section
+    And Pool: the checklist is marked as MANDATORY
+
+  Scenario: Checklist item 1 — CHANGELOG.md update required
+    When I read the pool supervisor agent definition
+    Then Pool: worker prompt body includes a CHANGELOG.md checklist item
+    And Pool: the item instructs workers to add an entry under the Unreleased section
+
+  Scenario: Checklist item 2 — CONTRIBUTORS.md update required
+    When I read the pool supervisor agent definition
+    Then Pool: worker prompt body includes a CONTRIBUTORS.md checklist item
+    And Pool: the item instructs workers to add or update their contribution entry
+
+  Scenario: Checklist item 3 — commit footer required
+    When I read the pool supervisor agent definition
+    Then Pool: worker prompt body includes a commit footer checklist item
+    And Pool: the item specifies the ISSUES CLOSED footer format
+
+  Scenario: Checklist item 4 — CI must pass before PR creation
+    When I read the pool supervisor agent definition
+    Then Pool: worker prompt body includes a CI passes checklist item
+    And Pool: the item instructs workers to verify all quality gates are green
+
+  Scenario: Checklist item 5 — BDD/Behave tests required
+    When I read the pool supervisor agent definition
+    Then Pool: worker prompt body includes a BDD tests checklist item
+    And Pool: the item instructs workers to add or update Behave feature files
+
+  Scenario: Checklist item 6 — Epic reference required in PR description
+    When I read the pool supervisor agent definition
+    Then Pool: worker prompt body includes an Epic reference checklist item
+    And Pool: the item instructs workers to reference the parent Epic issue number
+
+  Scenario: Checklist item 7 — Labels must be applied
+    When I read the pool supervisor agent definition
+    Then Pool: worker prompt body includes a labels checklist item
+    And Pool: the item instructs workers to apply labels via forgejo-label-manager
+
+  Scenario: Checklist item 8 — Milestone must be assigned
+    When I read the pool supervisor agent definition
+    Then Pool: worker prompt body includes a milestone checklist item
+    And Pool: the item instructs workers to assign the earliest open milestone
+
+  Scenario: All 8 checklist items are present in the worker prompt
+    When I read the pool supervisor agent definition
+    Then Pool: worker prompt body contains all 8 mandatory checklist items
