Phase 2 Governance Quality Checklist

Feature ID: phase2-governance Generated: 2026-01-24 Status: Complete Completion Date: 2026-01-25 PR: #72 (merged to develop)

Pre-Implementation Checklist

Environment Readiness

  • Rust toolchain up to date (rustup update)
  • CCH v1.0.0 codebase checked out
  • All existing tests pass (cargo test)
  • Clippy reports no warnings
  • Cargo fmt applied

Understanding Verification

  • Reviewed spec.md thoroughly
  • Reviewed plan.md for dependencies
  • Understood backward compatibility requirements
  • Reviewed existing Rule struct implementation
  • Reviewed existing LogEntry struct implementation

User Story Acceptance Checklists

US-GOV-01: Rule Metadata (Provenance) ✅

Functional Requirements

  • Rules support optional metadata block
  • author field parses correctly (String)
  • created_by field parses correctly (String)
  • reason field parses correctly (String)
  • confidence field parses correctly (high/medium/low)
  • last_reviewed field parses correctly (String date)
  • ticket field parses correctly (String)
  • tags field parses correctly (Vec)
  • Metadata is ignored by matcher engine (no runtime impact)
  • Metadata is included in log entries
  • Metadata is displayed by cch explain rule <name>

Backward Compatibility

  • Existing configs without metadata parse correctly
  • Partial metadata (some fields only) parses correctly
  • Empty metadata block metadata: {} handled

Edge Cases

  • Very long reason strings (>1000 chars)
  • Special characters in author name
  • Empty tags array tags: []
  • Invalid confidence value → clear error message

US-GOV-02: Policy Modes ✅

Functional Requirements

  • Rules support optional mode field
  • enforce mode works (current behavior)
  • warn mode: Never blocks, injects warning instead
  • audit mode: No injection, no blocking, logs only
  • Default mode is enforce when not specified
  • Mode is case-insensitive (Enforce, ENFORCE, enforce)
  • Mode is included in log entries
  • Mode is displayed by cch explain rule <name>

Mode Behavior Verification

Test Case Mode Expected Status
Block action enforce Blocks ✅
Block action warn Injects warning, doesn't block ✅
Block action audit Logs only, no action ✅
Inject action enforce Injects ✅
Inject action warn Injects ✅
Inject action audit Logs only ✅
Run action enforce Runs validator ✅
Run action warn Runs validator ✅
Run action audit Logs only ✅

Edge Cases

  • Invalid mode value → clear parse error
  • Mode + block_if_match combination works correctly

US-GOV-03: Rule Priority ✅

Functional Requirements

  • Rules support optional priority field (integer)
  • Higher numbers run first
  • Default priority is 0
  • Rules sorted by: 1) priority (desc), 2) file order (stable)
  • Priority is included in log entries
  • Priority is displayed by cch explain rule <name>

Sorting Verification

  • Priority 100 runs before priority 50
  • Priority 50 runs before priority 0 (default)
  • Same priority preserves file order
  • Negative priorities allowed and work correctly

Edge Cases

  • Very large priority (i32::MAX)
  • Negative priority (-100)
  • All rules same priority → file order preserved
  • Invalid priority (non-integer) → clear parse error

US-GOV-04: Policy Conflict Resolution ✅

Functional Requirements

  • Conflict resolution follows explicit rules (not emergent)
  • enforce mode wins over warn and audit
  • Among same modes, higher priority wins
  • Multiple blocks: highest priority block message used
  • Conflict resolution logged for debugging

Conflict Resolution Matrix

Scenario Expected Winner Status
enforce(100) + warn(50) enforce(100) ✅
enforce(50) + warn(100) enforce(50) - mode wins over priority ✅
audit(100) + enforce(50) enforce(50) ✅
warn(100) + warn(50) warn(100) - higher priority ✅
audit(100) + audit(50) audit(100) - higher priority ✅
enforce(100) + enforce(50) enforce(100) - higher priority message ✅

US-GOV-05: Enhanced cch explain rule Command ✅

Functional Requirements

  • Command: cch explain rule <rule-name>
  • Displays: name correctly
  • Displays: event type correctly
  • Displays: mode (with default indicator)
  • Displays: priority (with default indicator)
  • Displays: matchers configuration
  • Displays: action configuration
  • Displays: full metadata block
  • Displays: recent activity (trigger count, block count, last trigger)
  • Supports --json output format
  • Supports --no-stats flag

Edge Cases

  • Rule not found → clear error message
  • Rule with no metadata → shows "No metadata"
  • No log entries → shows "No recent activity"
  • Very old log entries → handles gracefully
  • Log file missing → graceful degradation

US-GOV-06: Enhanced Logging Schema ✅

Functional Requirements

  • Log entries include mode field when present
  • Log entries include priority field when present
  • Log entries include metadata block (if present)
  • Log entries include decision field (allowed/blocked/warned/audited)
  • JSON Lines format maintained
  • Backward compatible (new fields are additive)

Log Entry Verification

{
  "timestamp": "required",
  "session_id": "required",
  "event": "required",
  "rule_name": "required",
  "mode": "optional - only if rule has mode",
  "priority": "optional - only if rule has priority",
  "decision": "required for matched rules",
  "metadata": "optional - only if rule has metadata"
}

✅ All fields implemented and tested

Backward Compatibility

  • Existing log parsers don't break
  • Optional fields use skip_serializing_if = "Option::is_none"
  • Log file format still valid JSON Lines

US-GOV-07: Validator Trust Levels ✅

Functional Requirements

  • run action supports optional trust field
  • Trust levels: local | verified | untrusted
  • v1.1: Informational only (no enforcement)
  • Trust level logged in entries
  • Both simple and extended formats work

Format Compatibility

# Simple format (must still work)
actions:
  run: .claude/validators/check.py

# Extended format (new)
actions:
  run:
    script: .claude/validators/check.py
    trust: local

✅ Both formats verified working

Technical Quality Checklists

Regression Test Suite

Critical Paths

  1. v1.0 config → parse → match → execute → log (unchanged behavior)
  2. v1.1 config with mode=enforce → blocks correctly
  3. v1.1 config with mode=warn → warns correctly
  4. v1.1 config with mode=audit → logs only
  5. Priority sorting → higher priority runs first
  6. cch explain rule → displays all fields
  7. Log entries → contain all governance fields

Edge Cases

  1. Mixed v1.0 and v1.1 rules in same config
  2. Rule with all governance fields
  3. Rule with no governance fields
  4. Empty metadata block
  5. Invalid mode value → parse error
  6. Conflict between 10+ matching rules

Error Scenarios

  1. Invalid mode → clear error with line number
  2. Invalid confidence → clear error with line number
  3. Invalid trust level → clear error with line number
  4. Malformed metadata → clear error with context
