-# Rule: Clean Code Principles and Enforcements
-
-Description:
-This rule enforces concrete clean-code practices across the repository. It complements existing high-level rules (TDD, linting, formatting, coverage) by adding behavioral and API-consistency checks, with deterministic commands and examples.
-
-Why:
-
-- Reduce cognitive load and debugging time by standardizing error handling, return types, logging, and small, single-purpose functions.
-- Make automated checks (pre-commit/CI) able to catch non-style problems (bare-excepts, prints, mixed return semantics, state-machine/config mismatches).
-
-Scope:
-Applies to all python files under src/ and tests/ and any state-machine generation artifacts.
-
-Enforcement checklist (machine-checkable where possible):
-
-1. No bare except or broad except Exception without re-raising or logging full context
-   - Rationale: Broad excepts hide real failures.
-   - Check: run pylint with a custom plugin or flake8 rule to detect "except:" or "except Exception:" that either:
-     - swallow the exception without re-raising, or
-     - do not call logger.exception(...) (stack trace).
-   - Command (CI): flake8 --select E722,B001 (or custom check)
-   - Example (bad):
-     try:
-         ...
-     except Exception:
-         pass
-   - Example (good):
-     except SpecificError as e:
-         logger.error("...: %s", e)
-         raise
-
-2. No direct print() calls in library modules
-   - Rationale: Use LoggerSetup for structured logs and session IDs.
-   - Check: grep for "print(" in src/ and tests/ (fail in src/)
-   - Command (CI): git grep -n -- '^\s*print\(' -- src/ && fail
-   - Fix: Replace print with LoggerSetup.get_logger(...) or setup_logger(...)
-
-3. Enforce consistent return types (avoid implicit None/False mixing)
-   - Rationale: Functions exposed as API should have typed, predictable returns.
-   - Rules:
-     - Publishing/IO methods must return bool (True/False), not None. If underlying library returned int, normalize.
-     - connect() should return bool only.
-   - Check: static analysis rule or unit test that asserts function annotations and runtime contract on a selection of public functions (RedisClient.publish/connect, MessagingStandardization.*)
-   - Example (good):
-     def publish(...) -> bool: ...
-     return True/False
-
-4. Prefer specific exceptions & re-raise after logging
-   - Rationale: Keep failure semantics explicit for callers and tests.
-   - Rule: Do not swallow exceptions. If a function handles and cannot continue, raise a domain-specific exception or re-raise.
-
-5. Limit line / function complexity
-   - Rationale: Keep functions short and single-responsibility.
-   - Rules:
-     - Maximum function length: 120 lines (configurable)
-     - Maximum cyclomatic complexity: 12
-   - Check: use radon cc --total-average and flake8-ext or pylint thresholds
-   - Command (CI): radon cc -nc -s src/ && fail if any > 12
-
-6. Use centralized logging, never ad-hoc formatting
-   - Rationale: Keep consistent format and redaction.
-   - Rules:
-     - Use LoggerSetup.get_logger or setup_logger to obtain logger.
-     - No module-level printing of messages; message flow logs should go via agent_flow logger.
-   - Check: grep for 'logging.getLogger(' and verify consistent usage, grep for 'print(' (see rule 2).
-
-7. Avoid filesystem operations with overly permissive modes
-   - Rationale: 0o777 should not be used by default.
-   - Rule: mkdir/os.makedirs must not be invoked with mode=0o777. Use 0o755 or use environment-controlled mode.
-   - Check: grep for '0o777' and require explicit justification in code comments; CI should flag occurrences.
-
-8. State machine / YAML consistency check
-   - Rationale: Generated state machines must match canonical YAML config.
-   - Rule: Add a unit/regression test that:
-     - reloads src/common/*.py generated state machine enums and compares state names and transitions to autodev_config.yaml and productplan_config.yaml
-     - fails the build if mismatch or case differences are present
-   - Check: add tests/unit/test_state_machine_config_sync.py
-   - Command (CI): hatch test tests/unit/test_state_machine_config_sync.py
-
-9. No side-effects at import time
-   - Rationale: Module imports should be safe and predictable for tests and tools.
-   - Rule: Avoid heavy I/O or network calls on import. get_runtime_logs_dir may create directories — allowed only if idempotent and documented; avoid network calls or spawn threads.
-   - Check: grep for network or redis connection calls at module-level (e.g., RedisSDK(...)).
-
-10. Async / signal safety
-    - Rationale: Signal handlers must not call non-signal-safe operations.
-    - Rule: Signal handlers may only set a flag or call a thread-safe routine; do not call asyncio.create_task directly from a POSIX signal handler.
-    - Check: grep for "signal.signal(" and assert handler functions only set flags or use loop.call_soon_threadsafe.
-    - Suggested fix: replace create_task calls in handler with loop.call_soon_threadsafe(lambda: asyncio.create_task(...))
-
-11. Secure secret redaction guaranteed
-    - Rationale: Sensitive keys must be masked in logs.
-    - Rule: LoggerSetup.redact_secrets must be covered by unit tests for nested dicts and strings.
-    - Check: add tests/unit/test_logger_redaction.py
-
-12. Messaging coercion & strict validation
-    - Rationale: Legacy message coercion is useful but must be exercised and tested.
-    - Rule: Any place that uses coercion (MessagingStandardization.process_standardized_message) must have tests that validate coercion success/failure and metrics increments.
-    - Check: add unit tests that assert contextschema_coercion_success/failed metrics behave as expected.
-
-13. Enforce pre-commit & CI gating
-    - Add pre-commit config that runs: black, isort, mypy, flake8 (with B/C plugins), radon, tests for state machine sync.
-    - CI job must fail on:
-      - lint failures
-      - radon/cyclomatic complexity
-      - state-machine config mismatch test
-      - flake8 error codes for prints and bare excepts
-
-14. Documentation/commit habits
-    - Rule: Any code change that modifies public API, state machine YAMLs, or generated state machine outputs MUST:
-      - include/modify a unit test covering new behavior
-      - update docs/ and CHANGELOG.md
-      - include 'BREAKING' section in PR if public API changed
-    - Check: CI script that rejects PRs lacking test files changed when src/ is modified (heuristic).
-
-Implementation guidance (how to add tests / checks quickly)
-
-- Add a lightweight pytest module for state-machine YAML<->enum sync (example included in docs).
-- Add flake8 plugin rules or configure pylint to error on 'print' and bare excepts; enable in CI config.
-- Add radon complexity check step to pipeline; fail if thresholds exceeded.
-- Add a small assertion test for RedisClient.publish return normalization.
-
-Mapping to existing rules (what to augment)
-
-- docs/rules/python-github-rules.md: Add explicit "no-bare-except" and "no-print" items and function complexity thresholds.
-- docs/rules/spec-fact-cli-rules.md: Add "state-machine YAML / generated code sync check" and "normalize public API return types".
-- docs/rules/testing-and-build-guide.md: Add specific test files to run (state-machine sync test, logger redaction tests) and mention radon/complexity checks.
-- .cursor/rules/testing-and-build-guide.mdc and .cursor/rules/python-github-rules.mdc: include exact CLI commands and required test files (see enforcement checklist).
-
-Developer notes (priorities)
-
-1. Add the state-machine sync unit test (high value, low effort).
-2. Add flake8/pylint rule to detect print/bare-except (medium effort).
-3. Normalize RedisClient.publish/connect return values & add tests (low-to-medium effort).
-4. Add radon step to CI and fix top offenders iteratively (ongoing).
-5. Replace print() in AutoDevStateMachine.log with LoggerSetup.get_logger (small change, run tests).
+# Rule: Clean-Code Principles and Review Gate
 
----
+## Charter source of truth
+
+The canonical 7-principle clean-code charter lives in:
+- **Policy-pack**: `specfact/clean-code-principles` (shipped by `specfact-cli-modules`)
+- **Skill file**: `skills/specfact-code-review/SKILL.md` in `nold-ai/specfact-cli-modules`
+
+This file is an **alias surface** for the specfact-cli repository. It maps each
+principle to its review category and records the Phase A gate thresholds so that
+contributors, reviewers, and AI coding agents operate from the same reference
+without duplicating the full charter text.
+
+## The 7 clean-code principles
+
+| # | Principle | Review category |
+|---|-----------|-----------------|
+| 1 | **Meaningful Naming** — identifiers reveal intent; avoid abbreviations | `naming` |
+| 2 | **KISS** — keep functions and modules small and single-purpose | `kiss` |
+| 3 | **YAGNI** — do not add functionality until it is needed | `yagni` |
+| 4 | **DRY** — single source of truth; eliminate copy-paste duplication | `dry` |
+| 5 | **SOLID** — single responsibility, open/closed, Liskov, interface segregation, dependency inversion | `solid` |
+| 6 | **Small, focused functions** — each function does exactly one thing (subsumed by KISS metrics) | `kiss` |
+| 7 | **Self-documenting code** — prefer expressive code over inline comments; comments explain *why* not *what* | `naming` |
+
+## Active gate: Phase A KISS metrics
+
+The following thresholds are **enforced** through the `specfact code review run`
+gate and the pre-commit hook (`scripts/pre_commit_code_review.py`):
+
+| Metric | Warning | Error |
+|--------|---------|-------|
+| Lines of code per function (LOC) | > 80 (warning) | > 120 (error) |
+| Nesting depth | configurable (phase A) | configurable (phase A) |
+| Parameter count | configurable (phase A) | configurable (phase A) |
+
+Nesting-depth and parameter-count checks are **active** in Phase A.
+
+### Phase B (deferred)
+
+Phase B thresholds (`> 40` warning / `> 80` error for LOC) are planned for a
+future cleanup change once the initial Phase A remediation is complete.
+**Phase B is not yet a hard gate.** Do not silently promote Phase B thresholds
+when configuring or extending the review gate.
+
+## Review categories consumed by this repo
+
+When `specfact code review run` executes against this codebase the following
+clean-code categories from the expanded review module are included:
+
+- `naming` — semgrep naming and exception-pattern rules
+- `kiss` — radon LOC/nesting/parameter findings under Phase A thresholds
+- `yagni` — AST-based unused-abstraction detection
+- `dry` — AST clone-detection and duplication findings
+- `solid` — AST dependency-role and single-responsibility checks
+
+Zero regressions in these categories are required before a PR is merge-ready.
+
+## Per-principle enforcement notes
+
+### Naming (`naming`)
+
+- Identifiers in `src/` must use `snake_case` (modules/functions), `PascalCase` (classes), `UPPER_SNAKE_CASE` (constants).
+- Avoid single-letter names outside short loop variables.
+- Exception patterns must not use broad `except Exception` without re-raising or logging.
+
+### KISS (`kiss`)
+
+- Maximum function length: **120 lines** (Phase A error threshold).
+- Maximum cyclomatic complexity: **12** (radon `cc` threshold; `>= 16` is error band).
+- Phase A LOC warning at > 80, error at > 120.
+
+### YAGNI (`yagni`)
+
+- Do not add configuration options, flags, or extension points until a concrete use-case drives them.
+- Remove dead code paths rather than commenting them out.
+
+### DRY (`dry`)
+
+- Do not copy-paste logic; extract to a shared function or module.
+- Single source of truth for schemas (Pydantic `BaseModel`), constants (`UPPER_SNAKE_CASE`), and templates (`resources/templates/`).
+
+### SOLID (`solid`)
+
+- Each module/class has a single clearly named responsibility.
+- Extend via dependency injection (adapters pattern) rather than modifying existing classes.
+- Use `@icontract` (`@require`/`@ensure`) and `@beartype` on all public APIs.
+
+## Additional behavioral rules (complement SOLID/KISS)
+
+- No `print()` calls in `src/` — use `from specfact_cli.common import get_bridge_logger`.
+  *(Note: T20 is currently ignored in pyproject.toml and not enforced by the review gate; this is aspirational.)*
+- No broad `except Exception` without re-raising or logging.
+  *(Note: W0718 is disabled in .pylintrc; broad-exception checks are aspirational.)*
+- No side-effects at import time (no network calls, no file I/O on module load).
+- Signal handlers must only set a flag or use `loop.call_soon_threadsafe`.
+- Filesystem modes must not use `0o777`; use `0o755` or environment-controlled mode.
+- Secret redaction via `LoggerSetup.redact_secrets` must be covered by unit tests.
 
-Changelog / Expected follow-up
+## Pre-commit and CI enforcement
 
-- After adding these rules, update CI to run the new checks and add sample unit tests that fail on violations.
-- Run hatch test and the new linters locally; fix top offenders in an iterative PR with small, focused commits.
+The `specfact-code-review-gate` pre-commit hook and the `hatch run specfact code
+review run --json --out .specfact/code-review.json` command both enforce these
+principles. Run the review before submitting a PR and resolve every finding.

+## Clean-Code Charter
+
+This repository enforces the **7-principle clean-code charter** defined in:
+- `skills/specfact-code-review/SKILL.md` (`nold-ai/specfact-cli-modules`)
+- Policy-pack: `specfact/clean-code-principles`
+
+Review categories checked on every PR: **naming · kiss · yagni · dry · solid**
+
+Phase A KISS thresholds: LOC > 80 warning / > 120 error per function.
+Nesting-depth and parameter-count checks are active. Phase B (>40/80) is deferred.
+
+Run `hatch run specfact code review run --json --out .specfact/code-review.json` before submitting.
+
+## Key conventions
+
+- Python 3.11+, Typer CLI, Pydantic models, `@icontract` + `@beartype` on all public APIs
+- No `print()` in `src/` — use `get_bridge_logger()`
+- Branch protection: work on `feature/*`, `bugfix/*`, `hotfix/*` branches; PRs to `dev`
+- Pre-commit checklist: `hatch run format` → `type-check` → `lint` → `yaml-lint` → `contract-test` → `smart-test`

 Before modifying application code, **always** verify that an active OpenSpec change in `openspec/changes/` **explicitly covers the requested modification**. This is the spec-driven workflow defined in `openspec/config.yaml`. Skip only when the user explicitly says `"skip openspec"` or `"implement without openspec change"`.

+- [x] 1.2 Confirm `code-review-zero-findings` has recorded a zero-finding self-review baseline and that the modules repo change `clean-code-02-expanded-review-module` is available for consumption.
+- [x] 1.3 Reconfirm scope against the 2026-03-22 clean-code implementation plan and the updated `openspec/CHANGE_ORDER.md`.
 
 ## 2. Spec-first and test-first preparation
 
-- [ ] 2.1 Finalize `specs/` deltas for clean-code charter references, clean-code compliance gating, and staged LOC/nesting checks.
-- [ ] 2.2 Add or update tests derived from the new scenarios before touching production code.
-- [ ] 2.3 Run targeted tests and capture failing-first evidence in `TDD_EVIDENCE.md`.

 ## 3. Implementation
 
-- [ ] 3.1 Update instruction surfaces (`AGENTS.md`, `CLAUDE.md`, `.cursor/rules/clean-code-principles.mdc`, `.github/copilot-instructions.md`, relevant `.codex` skill entry points) to reference the canonical clean-code charter.
-- [ ] 3.2 Wire specfact-cli review and CI flows to consume the expanded clean-code categories from the modules repo without introducing a second clean-code configuration model.
-- [ ] 3.3 Adopt Phase A LOC, nesting-depth, and parameter-count checks through the review integration path and preserve the Phase B thresholds as a later change.

+
+## 6. Review findings remediation (post-implementation)
+
+- [x] 6.1 Fix coderabbitai review findings:
+  - Updated `.cursor/rules/clean-code-principles.mdc` to clarify T20 and W0718 are aspirational
+  - Added language specifier to fenced code block in `TDD_EVIDENCE.md`
+  - Updated test to check for all 7 canonical principles
+  - Made LOC threshold assertion more specific with exact strings
+- [x] 6.2 Verify CHANGELOG.md is updated with version 0.44.0 and all change details
+- [x] 6.3 Update task status to reflect completion
