## Executive Summary

Analysis of 50+ recent GitHub issues across the paiml organization using the organizational-intelligence-plugin, combined with analysis of recent bug fixes across the sovereign stack (trueno, aprender, realizar, apr-model-qa-playbook, batuta), revealed **seventeen critical gaps** in `pmat comply`:

### Original Findings (v1.0)
1. **Stub SATD Undetected**: Code-level stubs (`todo!()`, `unimplemented!()`) escape all current checks
2. **GPU Quality Blind Spots**: Shared memory and barrier divergence bugs cause CUDA_ERROR_700
3. **No Code vs Comment SATD Distinction**: Runtime-panic stubs treated same as benign TODOs

### New Findings from Sovereign Stack Bug Analysis (v2.0)
4. **Critical `.unwrap()` in Production**: batuta's safety fixes show `.unwrap()` causing production panics
5. **Dependency Version Drift**: batuta/apr-model-qa-playbook fixes reveal stack version synchronization issues
6. **Flaky Test Patterns**: trueno's 7 timing-related fixes expose undetected test instability
7. **Data Corruption Anti-Patterns**: aprender/realizar GGUF fixes show model I/O bugs escaping detection
8. **Platform Compatibility Gaps**: trueno's WASM/ARM64 fixes reveal untested platform-specific code

### Additional Findings from OIP Tarantula Analysis (v2.1)
9. **NaN-Unsafe Comparisons**: `partial_cmp().unwrap()` panics on NaN values in ML code (10 instances)
10. **Lock Poisoning Vulnerabilities**: `.lock().unwrap()` cascades failures after thread panic (10 instances)
11. **Serde Deserialization Panics**: `from_str().unwrap()` crashes on malformed JSON/YAML (15+ instances)
12. **Undocumented Ignored Tests**: `#[ignore]` without explanation becomes permanent debt (6 tests)
13. **Low Coverage Thresholds**: 58% threshold is below 80% industry standard

### Coverage Quality & Test Performance Findings (v2.2)
14. **Coverage Exclusion Gaming**: Excessive `--ignore-filename-regex` patterns inflate coverage artificially (50+ patterns hiding >50% LOC)
15. **Slow Test Detection**: Individual tests taking >60s destroy developer flow ([SLOW-001] Luo et al. 2014)
16. **Slow Coverage**: Coverage runs >10min discourage measurement, causing coverage regression ([PERF-001] certeza spec)

### Dead Code & TDG Integration Findings (v2.3)
17. **Dead Code Undetected**: `pmat analyze dead-code` reports 0% dead code but rustc `#[warn(dead_code)]` and manual inspection reveal significant unreachable code. Dead code inflates coverage denominators and hides technical debt. **Not part of TDG scoring.**
18. **Public API Blindspot**: `rustc`'s `dead_code` lint treats all `pub` items as "live" (reachable) because they *might* be used by external crates, even in a binary or private workspace crate where they are definitely unused. This leaves a massive blindspot for "zombie public code".

### Batuta RAG Oracle Integration (v2.4 - NEW)
19. **No Contextual Fix Suggestions**: When violations are detected, developers must search documentation manually for the correct fix pattern. The batuta RAG oracle indexes the entire sovereign stack documentation but isn't leveraged.
20. **Missing Cross-Project Pattern Enforcement**: Different projects in the stack drift into inconsistent patterns (error handling, logging, testing conventions) without automated detection.
21. **No Smart Project Initialization**: New projects manually configure quality gates without guidance on appropriate thresholds for their project type.

This specification defines **25 improvements** with peer-reviewed justification, work tickets, and a **215-point Popperian falsification suite**.

## 1. Problem Analysis

### 1.1 Evidence from Organizational Intelligence

**Analysis Method**: Used `oip analyze --org paiml` across 25 repositories, 2,500 commits.

#### Trend A: Stub SATD Not Caught

**Current State**: `satd_detector.rs` detects comment-based SATD only.

**Evidence** (production code with undetected stubs):
```
src/services/quality_proxy.rs:    unimplemented!()
src/services/detection/integration_tests.rs:    unimplemented!()
examples/issue_053_batch2_context_churn.rs:    unimplemented!()
```

**Root Cause** (Five Whys):
1. Why are stubs in production? → Developers use `todo!()` as placeholders
2. Why aren't they caught? → SATD detector only checks comments
3. Why only comments? → Original design based on Potdar & Shihab (2014) comment mining
4. Why not extended? → No specification required code-level detection
5. Why no specification? → Gap in requirements discovery

#### Trend B: GPU Corruption Quality Issues

**Affected Issues**:
| Issue | Repository | Description | Root Cause |
|-------|------------|-------------|------------|
| #32 | realizar | FP32 FlashAttention OOB K access | Loop variable misuse |
| #37 | realizar | TiledQ4KGemvKernel shared memory bug | Boundary condition missing |
| #69 | trueno | Tiled GEMM early exit breaks barriers | `bra exit` before `bar.sync` |
| #77 | trueno | CUDA_ERROR_UNKNOWN (700) | Illegal memory access |

**Pattern**: All issues share common anti-patterns detectable via static analysis.

#### Trend C: False Positives Degrading Trust

**Evidence**:
- Issue #131: TDG falsely flags `.unwrap()` in doc comments
- bashrs: 10+ closed false positive issues (SC2128, IDEM003, etc.)

**Impact**: Developers ignore valid warnings due to noise.

### 1.2 New Findings from Sovereign Stack Bug Analysis

**Analysis Method**: Examined recent bug fixes (last 2 weeks) across trueno, aprender, realizar, apr-model-qa-playbook, and batuta repositories. Identified 32 bug fixes with recurring patterns.

#### Trend D: Critical `.unwrap()` Causing Production Panics

**Evidence** (batuta commit history):
```
fix(safety): replace critical unwrap() calls with proper error handling
```

**Root Cause** (Five Whys):
1. Why did production panic? → `.unwrap()` on `None` value
2. Why was `.unwrap()` used? → Developer assumed value always present
3. Why wasn't this caught in review? → No static analysis for `.unwrap()` patterns
4. Why no static analysis? → Clippy's `unwrap_used` lint is off by default
5. Why not enabled? → Too noisy without context-aware filtering

**Pattern**: 3 safety-critical fixes in batuta alone; extrapolating to stack = high-frequency issue.

#### Trend E: Dependency Version Drift

**Evidence** (batuta/apr-model-qa-playbook commits):
```
fix: update dependency versions to fix stack drift
fix(ci): remove path dependencies for CI compatibility
fix(lib): Export FingerprintConfig and ValidateStatsConfig  # Missing exports
chore(release): v0.6.2 - fix bashrs dependency to 6.59
```

**Root Cause** (Five Whys):
1. Why did build fail? → Version mismatch between workspace crates
2. Why mismatch? → Manual version updates across multiple repos
3. Why manual? → No automated drift detection
4. Why no detection? → No specification for cross-repo version validation
5. Why no specification? → Gap in dependency management requirements

**Impact**: 4 version-related fixes in 2 weeks = ~100 developer-hours/year wasted.

#### Trend F: Flaky Test Patterns

**Evidence** (trueno commit history):
```
fix: timing test margins + restore expect calls
fix: AVX-512 canary test flaky on CI
fix: f102 test timing issue
fix: f153 test margin widening
fix: f1110_large_sample timing
fix: macOS ARM64 support + ignore flaky CI test
```

**Root Cause** (Five Whys):
1. Why did CI fail intermittently? → Timing-based assertion failed
2. Why timing-based? → Test used `Instant::now()` with hard-coded margin
3. Why hard-coded? → Developer tested on fast machine, CI slower
4. Why not caught earlier? → No static detection of timing patterns
5. Why no detection? → Gap in test quality analysis

**Pattern**: 7 flaky test fixes in trueno = significant CI reliability impact.

#### Trend G: Data Corruption in Model I/O

**Evidence** (aprender/realizar commits):
```
fix(format): Transpose Q4_K/Q6_K tensors in GGUF->APR conversion  # P0 Critical
fix(format): Use matrix-aware Q4_K quantizer for dtype conversion
fix(GH-191): Fix GGUF->APR quantization data loss - dtype mapping mismatch
fix(format): Remove "model." prefix from GGUF->APR tensor name mapping
```

**Root Cause** (Five Whys):
1. Why was model output corrupt? → Tensor data in wrong orientation
2. Why wrong orientation? → Transpose missing in conversion path
3. Why missing? → Asymmetric serialization/deserialization code paths
4. Why asymmetric? → No roundtrip test validating bit-exact reconstruction
5. Why no roundtrip test? → Gap in model I/O testing requirements

**Impact**: P0 critical bugs affecting model inference accuracy.

#### Trend H: Platform Compatibility Gaps

**Evidence** (trueno commits):
```
fix: make hostname dependency target-specific for WASM compatibility
fix: macOS ARM64 support + ignore flaky CI test
fix(ci): remove path dependencies for CI compatibility
```

**Root Cause** (Five Whys):
1. Why did WASM build fail? → Dependency not available on wasm32
2. Why included? → Developer only tested on x86_64 Linux
3. Why not tested on WASM? → No CI job for wasm32 target
4. Why no CI job? → No validation that `#[cfg(...)]` blocks have matching CI coverage
5. Why no validation? → Gap in platform compatibility requirements

**Pattern**: Platform-specific bugs require expensive post-release fixes.

### 1.3 OIP Tarantula Fault Localization Analysis (NEW)

**Analysis Method**: Deep analysis of organizational-intelligence-plugin codebase, specifically the Tarantula spectrum-based fault localization (SBFL) module and supporting ML infrastructure. Identified 41+ instances of panic-prone patterns.

#### Trend I: NaN-Unsafe Floating Point Comparisons

**Evidence** (10 instances across ML code):
```rust
// src/ml.rs:84 - Will panic on NaN!
distances.sort_by(|a, b| a.0.partial_cmp(&b.0).unwrap());

// src/imbalance.rs:274
pairs.sort_by(|a, b| b.0.partial_cmp(&a.0).unwrap());

// src/classifier.rs:433
matches.sort_by(|a, b| b.1.partial_cmp(&a.1).unwrap());
```

**Root Cause** (Five Whys):
1. Why did ML prediction crash? → `.unwrap()` on `None` from `partial_cmp()`
2. Why was it `None`? → Comparison involved NaN (from 0.0/0.0 or infinity operations)
3. Why not caught? → Tests don't include NaN edge cases
4. Why use `partial_cmp()`? → f32/f64 don't implement `Ord`, only `PartialOrd`
5. Why no detection? → Gap in floating-point safety analysis

**Pattern**: ML distance/similarity calculations can produce NaN; 10 instances in OIP.

#### Trend J: Lock Poisoning Vulnerabilities

**Evidence** (10 instances in git.rs):
```rust
// src/git.rs:341, 378, 432, 584, 618, 632, 739, 796, 830, 844
index.write().unwrap();  // Panics if any thread panicked while holding lock
```

**Root Cause** (Five Whys):
1. Why did index operation crash? → Lock was poisoned
2. Why poisoned? → Previous thread panicked while holding write lock
3. Why panic cascaded? → `.unwrap()` on poisoned lock panics again
4. Why not `.unwrap_or_else(|e| e.into_inner())`? → Developer unaware of lock poisoning
5. Why no detection? → Gap in concurrency safety analysis

**Pattern**: Cascade failures from lock poisoning are silent until runtime.

#### Trend K: Serde Deserialization Panics

**Evidence** (15+ instances):
```rust
// src/tarantula.rs:1298
let deserialized: FaultLocalizationResult = serde_json::from_str(&json).unwrap();

// src/github.rs:580
let repo: RepoInfo = serde_json::from_str(json).unwrap();

// src/citl.rs:1030
let export: DepylerExport = serde_json::from_str(json).unwrap();
```

**Root Cause** (Five Whys):
1. Why did API integration crash? → JSON parsing failed
2. Why did parsing fail? → Unexpected schema from external service
3. Why crash instead of error? → `.unwrap()` on deserialization Result
4. Why not `?` operator? → Copy-paste from examples, no review
5. Why no detection? → Gap in external data handling analysis

**Pattern**: External data (JSON, YAML, TOML) can always be malformed.

#### Trend L: Undocumented Ignored Tests

**Evidence** (6 tests without explanation):
```rust
// src/pmat.rs:208 - No reason documented
#[ignore]
fn test_analyze_tdg_integration() {

// src/git.rs:470, 483, 503, 520 - No reason documented
#[ignore]
fn test_clone_small_repository() {

// vs. properly documented (src/gpu_correlation.rs:345):
#[ignore] // Requires GPU hardware  ← Good: reason given
async fn test_gpu_engine_creation() {
```

**Root Cause** (Five Whys):
1. Why is test permanently ignored? → Unknown - no documentation
2. Why no documentation? → Developer didn't explain when adding `#[ignore]`
3. Why not caught in review? → No lint rule requiring reason
4. Why no lint rule? → Gap in test quality requirements
5. Why does this matter? → Ignored tests become permanent debt, masking real issues

**Pattern**: 6 tests ignored without reason = hidden technical debt.

#### Trend M: Low Coverage Threshold

**Evidence** (CI configuration):
```yaml
# .github/workflows/ci.yml
if (( $(echo "$COVERAGE < 58.0" | bc -l) )); then
  echo "Coverage decreased below 58%!"
```

**Root Cause** (Five Whys):
1. Why is threshold only 58%? → Historical debt; never raised
2. Why not raised? → Would fail CI immediately
3. Why would it fail? → 42% of code untested
4. Why untested? → No ratchet mechanism to prevent coverage regression
5. Why no ratchet? → Gap in quality gate configuration

**Industry Standard**: 80%+ coverage; 58% allows significant untested code paths.

### 2.17 PII & Secret Detection (NEW - v2.9)

**Problem**: Hardcoded secrets and PII (Personal Identifiable Information) in source code are a major security risk. `pmat comply` currently lacks a dedicated check for this.

**Proposed Check**: `CB-130` to detect potential PII and secrets using regex patterns and Shannon entropy analysis.

**Justification**:
- **Security**: Prevent accidental leakage of API keys, passwords, and tokens.
- **Privacy**: Ensure compliance with GDPR/CCPA by preventing hardcoded PII (emails, IPs, phones).
- **Best Practice**: Secrets should be in environment variables or vaults, not code.

## 3. Proposed Solutions

### 3.1 CB-050: Stub Detection Check [P0 CRITICAL]

**Justification**: [SATD-003] shows design debt (stubs) costs 2.3x more to fix. [SATD-004] confirms industrial projects have 40% more stubs.

**Detection Patterns**:
```rust
// File: src/cli/handlers/comply_cb_detect.rs

/// CB-050: Detect code-level stubs that can panic at runtime
pub fn detect_cb050_code_stubs(project_path: &Path) -> Vec<CbViolation> {
    let patterns = [
        // Rust explicit stubs
        (r"todo!\s*\(", "CB-050-A", "todo!() macro - will panic at runtime"),
        (r"unimplemented!\s*\(", "CB-050-B", "unimplemented!() macro - will panic"),
        (r#"panic!\s*\(\s*"not implemented"#, "CB-050-C", "panic with 'not implemented'"),
        // Empty function bodies (non-test, non-trait-default)
        (r"fn\s+\w+\s*\([^)]*\)\s*(?:->\s*[^{]+)?\s*\{\s*\}", "CB-050-D", "Empty function body"),
        // Python stubs
        (r"raise\s+NotImplementedError", "CB-050-E", "Python NotImplementedError stub"),
        (r"pass\s*#\s*(?:stub|todo|fixme)", "CB-050-F", "Python pass with stub comment"),
    ];

    scan_for_patterns(project_path, &patterns, &["rs", "py", "ts", "js"])
}
```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-050-A (todo!) | Critical | Runtime panic guaranteed |
| CB-050-B (unimplemented!) | Critical | Runtime panic guaranteed |
| CB-050-C (panic not impl) | Critical | Runtime panic guaranteed |
| CB-050-D (empty body) | Warning | May be intentional (trait default) |
| CB-050-E (NotImplementedError) | Critical | Python runtime exception |
| CB-050-F (pass stub) | Warning | Comment indicates intent |

### 3.2 CB-060: GPU Kernel Quality Checks [P1 HIGH]

**Justification**: [GPU-001] shows 23% of CUDA kernels have sync bugs. [GPU-002] confirms 39% are memory violations. Issues #32, #37, #69, #77 demonstrate this in paiml stack.

**Detection Patterns**:
```rust
// File: src/cli/handlers/comply_cb_detect.rs

/// CB-060: GPU kernel quality checks for ComputeBrick projects
pub fn detect_cb060_gpu_quality(project_path: &Path) -> Vec<CbViolation> {
    let mut violations = Vec::new();

    // CB-060-A: Barrier divergence (bra/branch before bar.sync)
    // Pattern: @%pN bra exit; ... bar.sync (exit before barrier)
    violations.extend(detect_ptx_barrier_divergence(project_path));

    // CB-060-B: Shared memory without bounds check
    // Pattern: ld.shared without preceding setp.lt bounds check
    violations.extend(detect_shared_memory_unbounded(project_path));

    // CB-060-C: Tiled kernel without boundary predicates
    // Pattern: tile loop without (row < M && col < N) guards
    violations.extend(detect_tiled_kernel_no_bounds(project_path));

    // CB-060-D: WGSL workgroupBarrier in divergent control flow
    violations.extend(detect_wgsl_barrier_divergence(project_path));

    violations
}

/// Detect PTX patterns where threads exit before reaching bar.sync
fn detect_ptx_barrier_divergence(project_path: &Path) -> Vec<CbViolation> {
    // From PARITY-114: @%p0 bra exit; before bar.sync 0;
    let pattern = r"@%p\d+\s+bra\s+\w+;[\s\S]{0,500}bar\.sync";
    scan_ptx_files(project_path, pattern, "CB-060-A",
        "Thread may exit before barrier - causes undefined behavior")
}
```

**GPU Anti-Pattern Catalog** (from issue analysis):

| ID | Anti-Pattern | Example (from issues) | Detection Strategy |
|----|--------------|----------------------|-------------------|
| CB-060-A | Early exit before barrier | PARITY-114: `@%p0 bra exit` before `bar.sync` | Regex: branch followed by barrier |
| CB-060-B | Unbounded shared memory | #32: `k_col_offset = local_col * head_dim` OOB | Check smem index vs tile size |
| CB-060-C | Missing tile boundary | #37: hidden_dim >= 1536 triggers bug | Verify predicated stores |
| CB-060-D | WGSL divergent barrier | CB-002 existing | Already in comply_cb_detect.rs |

### 3.3 SATD Code vs Comment Severity [P1 HIGH]

**Justification**: [SATD-002] shows SATD correlates with defects; code stubs are deterministic failures vs probabilistic comment-SATD.

**Implementation**:
```rust
// File: src/services/satd_detector.rs

/// SATD manifestation type affects severity
#[derive(Debug, Clone, Copy, PartialEq, Eq, Serialize, Deserialize)]
pub enum SATDManifestationType {
    /// Comment-based: // TODO, // FIXME - advisory only
    Comment,
    /// Code-based: todo!(), unimplemented!() - will crash at runtime
    Code,
}

impl SATDManifestationType {
    /// Code SATD escalates severity by one level
    pub fn severity_multiplier(&self) -> u8 {
        match self {
            SATDManifestationType::Comment => 1,
            SATDManifestationType::Code => 2, // Escalate
        }
    }
}

// Update TechnicalDebt struct
pub struct TechnicalDebt {
    pub category: DebtCategory,
    pub severity: Severity,
    pub manifestation: SATDManifestationType, // NEW
    pub text: String,
    pub file: PathBuf,
    pub line: u32,
    pub column: u32,
    pub context_hash: [u8; 16],
}
```

**Comply Integration**:
```rust
fn check_satd_code_level(project_path: &Path) -> ComplianceCheck {
    let detector = SATDDetector::new();
    let result = detector.analyze_project(project_path, false).await?;

    let code_satd: Vec<_> = result.items.iter()
        .filter(|d| d.manifestation == SATDManifestationType::Code)
        .collect();

    if !code_satd.is_empty() {
        ComplianceCheck {
            name: "Code-Level SATD".to_string(),
            status: CheckStatus::Fail,  // Code SATD always fails
            message: format!("{} code stubs found (todo!/unimplemented!)", code_satd.len()),
            severity: Severity::Critical,
        }
    } else {
        ComplianceCheck {
            name: "Code-Level SATD".to_string(),
            status: CheckStatus::Pass,
            message: "No runtime-panic stubs detected".to_string(),
            severity: Severity::Info,
        }
    }
}
```

### 3.4 OIP Defect Prediction Integration [P2 MEDIUM]

**Justification**: [TPS-001] Principle 5 emphasizes learning from past problems. OIP already mines defect patterns; integration prevents recurrence.

**Implementation**:
```rust
// File: src/cli/handlers/comply_handlers/check_handlers.rs

/// Check project against OIP historical defect patterns
fn check_oip_defect_patterns(project_path: &Path) -> ComplianceCheck {
    let oip_db = project_path.join(".oip").join("defects.db");

    if !oip_db.exists() {
        return ComplianceCheck {
            name: "OIP Defect Patterns".to_string(),
            status: CheckStatus::Skip,
            message: "No OIP analysis available - run 'oip analyze'".to_string(),
            severity: Severity::Info,
        };
    }

    // Load OIP defect patterns for this project
    let patterns = load_oip_patterns(&oip_db)?;

    // Check if current code matches historical defect patterns
    let matches = patterns.iter()
        .filter(|p| pattern_matches_current_code(p, project_path))
        .collect::<Vec<_>>();

    if matches.is_empty() {
        ComplianceCheck {
            name: "OIP Defect Patterns".to_string(),
            status: CheckStatus::Pass,
            message: "No historical defect patterns detected".to_string(),
            severity: Severity::Info,
        }
    } else {
        ComplianceCheck {
            name: "OIP Defect Patterns".to_string(),
            status: CheckStatus::Warn,
            message: format!("{} files match historical defect patterns", matches.len()),
            severity: Severity::Warning,
        }
    }
}
```

### 3.5 Suppression Infrastructure [P2 MEDIUM]

**Justification**: [FP-001] shows >50% FP rate causes abandonment. [FP-002] confirms context-aware suppression reduces FP 35%.

**Configuration Format**:
```toml
# .pmat/suppressions.toml

[meta]
version = "1.0"
last_updated = "2026-01-24"

# Global suppressions by check ID
[suppressions.CB-050]

[suppressions.CB-060]
# Suppress GPU checks in CPU-only test configurations
[[suppressions.CB-060.rules]]
condition = "!cfg(feature = 'cuda')"
reason = "GPU checks not applicable without CUDA feature"
```

**Implementation**:
```rust

#[derive(Debug, Deserialize)]
pub struct SuppressionConfig {
    pub meta: SuppressionMeta,
    pub suppressions: HashMap<String, CheckSuppressions>,

    pub expires: Option<NaiveDate>,   // Optional expiry
    pub condition: Option<String>,    // Conditional suppression
}

impl SuppressionConfig {
    pub fn should_suppress(&self, check_id: &str, file: &Path, line: u32) -> Option<&str> {
        let check_rules = self.suppressions.get(check_id)?;

        for rule in &check_rules.rules {
            // Check expiry
            if let Some(expires) = rule.expires {
                if Utc::now().naive_utc().date() > expires {
                    continue; // Suppression expired
                }
            }

            // Match pattern or specific file
            if let Some(pattern) = &rule.pattern {
                if glob_match(pattern, file) {
                    return Some(&rule.reason);
                }
            }

            if let Some(rule_file) = &rule.file {
                if file == rule_file {
                    if let Some(lines) = &rule.lines {
                        if lines.contains(&line) {
                            return Some(&rule.reason);
                        }
                    } else {
                        return Some(&rule.reason);
                    }
                }
            }
        }

        None
    }
}
```

### 3.6 CB-070: Critical `.unwrap()` Detection [P0 CRITICAL] (NEW)

**Justification**: [ERR-001] shows 35% of catastrophic failures from error handling bugs. [ERR-002] confirms 92% of critical failures due to incorrect error handling. batuta's recent safety fixes demonstrate this pattern in the sovereign stack.

**Source Evidence**: batuta commit `fix(safety): replace critical unwrap() calls with proper error handling`

**Detection Patterns**:
```rust
// File: src/cli/handlers/comply_cb_detect.rs

/// CB-070: Detect critical .unwrap() calls that can panic in production
pub fn detect_cb070_critical_unwrap(project_path: &Path) -> Vec<CbViolation> {
    let mut violations = Vec::new();

    // Scan production code (exclude tests, examples, benches)
    for file in walk_production_rs_files(project_path) {
        let content = fs::read_to_string(&file)?;
        let lines: Vec<&str> = content.lines().collect();
        let test_lines = compute_test_code_lines(&lines);

        for (line_num, line) in lines.iter().enumerate() {
            if test_lines.contains(&line_num) {
                continue; // Skip test code
            }

            // CB-070-A: .unwrap() on Result/Option
            if line.contains(".unwrap()") && !is_in_string_literal(line) {
                violations.push(CbViolation {
                    pattern_id: "CB-070-A".to_string(),
                    file: file.display().to_string(),
                    line: line_num + 1,
                    description: ".unwrap() can panic - use ? or .unwrap_or()".to_string(),
                    severity: Severity::Error,
                });
            }

            // CB-070-B: .expect() - lower severity (has message)
            if line.contains(".expect(") && !is_in_string_literal(line) {
                violations.push(CbViolation {
                    pattern_id: "CB-070-B".to_string(),
                    file: file.display().to_string(),

                    severity: Severity::Warning,
                });
            }

            // CB-070-C: panic!() outside of invariant assertions
            if line.contains("panic!(") && !line.contains("unreachable!")
                && !line.contains("assert") {
                violations.push(CbViolation {
                    pattern_id: "CB-070-C".to_string(),

                });
            }
        }
    }

    violations
}
```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-070-A (.unwrap()) | Error | Silent panic, no context |
| CB-070-B (.expect()) | Warning | Has panic message, may be intentional |
| CB-070-C (panic!()) | Warning | Explicit, may be invariant check |
| `.unwrap_or()` / `.unwrap_or_default()` | OK | Safe fallback |
| `?` operator | OK | Propagates error properly |

### 3.7 CB-080: Dependency Version Drift Detection [P1 HIGH] (NEW)

**Justification**: [DEP-001] shows 40% of projects lag 6+ months on updates. [DEP-002] confirms transitive deps introduce 40% of vulnerabilities. batuta's version drift fixes demonstrate real-world impact.

**Source Evidence**:
- batuta: `fix: update dependency versions to fix stack drift`
- batuta: `fix(ci): remove path dependencies for CI compatibility`
- apr-model-qa-playbook: `fix(lib): Export FingerprintConfig and ValidateStatsConfig`

**Detection Patterns**:
```rust
// File: src/cli/handlers/comply_cb_detect.rs

/// CB-080: Detect dependency version drift and compatibility issues
pub fn detect_cb080_dependency_drift(project_path: &Path) -> Vec<CbViolation> {
    let mut violations = Vec::new();
    let cargo_toml = project_path.join("Cargo.toml");

    if !cargo_toml.exists() {
        return violations;
    }

    let manifest = cargo_toml::Manifest::from_path(&cargo_toml)?;

    // CB-080-A: Path dependencies in non-dev sections (breaks CI/crates.io)
    for (name, dep) in &manifest.dependencies {
        if let Some(path) = dep.path() {
            violations.push(CbViolation {
                pattern_id: "CB-080-A".to_string(),
                file: cargo_toml.display().to_string(),
                line: 0, // TOML line detection TODO

                ),
                severity: Severity::Error,
            });
        }
    }

### 3.7.1 CB-081: Dependency Count & Health Detection [P1 HIGH] (NEW - v2.9)

**Justification**: Per rust-project-score-v1.1 spec, excessive dependencies degrade build times, inflate binary size, and increase supply chain attack surface. [DEP-002] confirms transitive deps introduce 40% of vulnerabilities.

**Source Evidence**:
- rust-project-score-v1.1-update.md: Dependency Health scoring (12 points total)
- pmat itself: 114 direct, 1019 transitive deps = score 0/5 (critical)

**Detection Patterns**:
```rust
// File: src/cli/handlers/comply_cb_detect.rs

/// CB-081: Dependency count and health analysis
pub struct DependencyCountReport {
    pub direct_count: usize,
    pub transitive_count: usize,
    pub score: u8,                    // 0-5 based on thresholds
    pub duplicate_crates: Vec<(String, Vec<String>)>,  // (name, [versions])
    pub feature_gated_count: usize,   // deps with default-features = false
    pub sovereign_count: usize,       // batuta stack crates used
    pub violations: Vec<CbPatternViolation>,
}

/// CB-081-A: Base dependency count scoring
/// Thresholds from rust-project-score-v1.1:
///   5 points: ≤20 direct, ≤100 transitive
///   4 points: ≤30 direct, ≤150 transitive
///   3 points: ≤40 direct, ≤200 transitive
///   2 points: ≤50 direct, ≤250 transitive
///   0 points: >50 direct or >250 transitive

/// CB-081-B: Duplicate crate detection
/// Parse Cargo.lock to find crates with multiple versions
/// Duplicates inflate binary size and compilation time

/// CB-081-C: Feature flag hygiene
/// Count deps using `default-features = false`
/// Higher percentage = better dependency hygiene (+1 point for >50%)

/// CB-081-D: Sovereign stack bonus
/// Award bonus for using batuta stack crates instead of external alternatives
/// +1 point per sovereign crate (max +3)
const SOVEREIGN_CRATES: &[&str] = &[
    "aprender", "trueno", "trueno-graph", "trueno-db", "trueno-rag",
    "trueno-viz", "trueno-zram-core", "pmcp", "presentar-core",
    "renacer", "certeza", "bashrs", "probar"
];

/// CB-081-E: Trend tracking
/// Store dependency counts in .pmat/metrics/dependencies.json
/// Warn when deps increase significantly between checks
```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-081-A (>50 direct or >250 transitive) | Error | Critical bloat, supply chain risk |
| CB-081-A (>40 direct or >200 transitive) | Warning | High dependency count |
| CB-081-A (>30 direct or >150 transitive) | Info | Moderate, room for improvement |
| CB-081-B (duplicate crates) | Warning | Binary bloat, version conflicts |
| CB-081-C (low feature gating) | Info | Optimization opportunity |
| CB-081-D (no sovereign crates) | Info | Consider batuta stack alternatives |
| CB-081-E (deps increased >10%) | Warning | Dependency creep detected |

**Output Format**:
```
CB-081: Dependency Count
  Direct: 35 (+3 since last check)
  Transitive: 180 (+12 since last check)
  Score: 3/5 (moderate)

  Duplicates: 2 crates with multiple versions
    - rand: 0.7.3, 0.8.5
    - syn: 1.0.109, 2.0.87

  Feature Hygiene: 45% deps use default-features = false
  Sovereign Stack: 3 crates (aprender, trueno, pmcp) [+3 bonus]

  Recommendations:
    - Run 'cargo tree --duplicates' to identify consolidation opportunities
    - Consider 'default-features = false' for: serde, tokio, reqwest
```

### 3.8 CB-090: Flaky Test Pattern Detection [P1 HIGH] (NEW)

**Justification**: [FLAKY-001] shows 4.56% of tests are flaky, 45% due to timing. [FLAKY-003] estimates $1.3M/year cost at large organizations. trueno's 7 flaky test fixes demonstrate pattern prevalence.

**Source Evidence**:
- trueno: `fix: timing test margins + restore expect calls`
- trueno: `fix: AVX-512 canary test flaky on CI`
- trueno: `fix: f102 test timing issue`
- trueno: `fix: macOS ARM64 support + ignore flaky CI test`

### 3.10 CB-110: Platform Compatibility Matrix Check [P1 HIGH] (NEW)

**Justification**: [PLAT-001] shows 18% of CI failures are platform-specific. [PLAT-002] confirms cross-platform bugs take 2.5x longer to fix. trueno's WASM/ARM64 fixes demonstrate real-world impact.

### 3.11 CB-120: NaN-Unsafe Comparison Detection [P0 CRITICAL] (NEW - OIP Tarantula)

**Justification**: [NAN-001] shows NaN comparison returns false, breaking sort invariants. [NAN-002] confirms NaN arises from ML distance calculations (0/0, inf-inf). OIP Trend I found 10 instances in production ML code.

**Source Evidence** (OIP ml.rs, imbalance.rs, classifier.rs):
```rust
// These WILL panic on NaN input:
distances.sort_by(|a, b| a.0.partial_cmp(&b.0).unwrap());  // ml.rs:84
pairs.sort_by(|a, b| b.0.partial_cmp(&a.0).unwrap());      // imbalance.rs:274
matches.sort_by(|a, b| b.1.partial_cmp(&a.1).unwrap());    // classifier.rs:433
```

**Detection Patterns**:
```rust
// File: src/cli/handlers/comply_cb_detect.rs

/// CB-120: Detect NaN-unsafe floating-point comparisons
pub fn detect_cb120_nan_unsafe(project_path: &Path) -> Vec<CbViolation> {

**Severity Mapping**:

| CB-120-B (min/max_by) | Error | Common in ML argmin/argmax |
| CB-120-C (sort_by) | Error | Common in k-NN, clustering |

**Fix**: Use `.unwrap_or(Ordering::Equal)` or `total_cmp()` (Rust 1.62+).

### 3.12 CB-121: Lock Poisoning Vulnerability Detection [P1 HIGH] (NEW - OIP Tarantula)

**Justification**: [LOCK-001] documents Rust's mutex poisoning semantics. [LOCK-003] shows concurrency primitives are common source of UB. OIP Trend J found 10 instances in git.rs.

**Source Evidence** (OIP git.rs:341, 378, 432, 584, 618, 632, 739, 796, 830, 844):
```rust
index.write().unwrap();  // Panics if any thread panicked while holding lock
```

**Detection Patterns**:
```rust
// File: src/cli/handlers/comply_cb_detect.rs

/// CB-121: Detect lock poisoning vulnerabilities
pub fn detect_cb121_lock_poisoning(project_path: &Path) -> Vec<CbViolation> {

        (r"\.lock\s*\(\s*\)\s*\.\s*unwrap\s*\(", "CB-121-A",
         ".lock().unwrap() panics if lock poisoned"),
        (r"\.read\s*\(\s*\)\s*\.\s*unwrap\s*\(", "CB-121-B",
         ".read().unwrap() panics on poisoned RwLock"),
        (r"\.write\s*\(\s*\)\s*\.\s*unwrap\s*\(", "CB-121-C",
         ".write().unwrap() panics on poisoned RwLock"),
    ];
    // Scan production code, skip tests
    // Suggest: .unwrap_or_else(|e| e.into_inner()) or propagate error
}
```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-121-A (.lock().unwrap()) | Warning | Cascade failure risk |
| CB-121-B (.read().unwrap()) | Warning | Read lock poisoning |
| CB-121-C (.write().unwrap()) | Warning | Write lock poisoning |

**Fix**: Use `.unwrap_or_else(|poisoned| poisoned.into_inner())` to recover.

### 3.13 CB-122: Serde Deserialization Safety [P1 HIGH] (NEW - OIP Tarantula)

**Justification**: [SERIAL-001] shows 23% of failures from data handling. OIP Trend K found 15+ instances of `from_str().unwrap()` on external JSON/YAML input.

**Source Evidence** (OIP tarantula.rs:1298, github.rs:580, citl.rs:1030):
```rust
let result: MyType = serde_json::from_str(&json).unwrap();  // External data!
let repo: RepoInfo = serde_json::from_str(json).unwrap();   // API response!
```

**Detection Patterns**:
```rust
// File: src/cli/handlers/comply_cb_detect.rs

/// CB-122: Detect unsafe deserialization patterns
pub fn detect_cb122_serde_unsafe(project_path: &Path) -> Vec<CbViolation> {
    let patterns = [
        (r"serde_json::from_str[^;]*\.unwrap\s*\(", "CB-122-A",
         "serde_json::from_str().unwrap() panics on malformed JSON"),
        (r"serde_json::from_value[^;]*\.unwrap\s*\(", "CB-122-B",
         "serde_json::from_value().unwrap() panics on type mismatch"),

        (r"toml::from_str[^;]*\.unwrap\s*\(", "CB-122-D",
         "toml::from_str().unwrap() panics on malformed TOML"),
    ];
    // Skip test code - test fixtures are controlled
    // Suggest: use ? operator with context
}
```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-122-A (JSON from_str) | Error | External data always untrusted |
| CB-122-B (JSON from_value) | Error | Runtime type mismatch |
| CB-122-C (YAML) | Error | Config/external data |
| CB-122-D (TOML) | Error | Config files can be malformed |

**Fix**: Use `?` with `.context()` or graceful fallback.

### 3.14 CB-123: Documented Ignored Tests [P2 MEDIUM] (NEW - OIP Tarantula)

**Justification**: [TEST-001] establishes test documentation as maintainability requirement. [TEST-002] shows 40% overhead reduction with docs. OIP Trend L found 6 tests ignored without reason.

**Source Evidence** (OIP pmat.rs:208, git.rs:470, 483, 503, 520, analyzer.rs:471):
```rust
// BAD - No reason:
#[ignore]
fn test_analyze_tdg_integration() { }

// GOOD - Documented:
#[ignore] // Requires GPU hardware
async fn test_gpu_engine_creation() { }
```

**Detection Patterns**:
```rust
// File: src/cli/handlers/comply_cb_detect.rs

/// CB-123: Ensure #[ignore] tests have documented reasons
pub fn detect_cb123_undocumented_ignore(project_path: &Path) -> Vec<CbViolation> {
    // Check for #[ignore] without:
    // 1. Inline comment: #[ignore] // reason
    // 2. Attribute: #[ignore = "reason"]
    // 3. Preceding comment line
}
```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-123-A (undocumented) | Warning | Technical debt accumulation |

**Fix**: Add `#[ignore] // reason` or `#[ignore = "reason"]`.

### 3.15 CB-124: Coverage Threshold Enforcement [P2 MEDIUM] (NEW - OIP Tarantula)

**Justification**: [COV-001] shows coverage correlates with defect detection up to 80%. [COV-002] confirms 80%+ is optimal. OIP Trend M found 58% threshold - 22 points below standard.

**Source Evidence** (OIP .github/workflows/ci.yml):
```yaml
if (( $(echo "$COVERAGE < 58.0" | bc -l) )); then  # Too low!
```

**Detection Patterns**:
```rust
// File: src/cli/handlers/comply_cb_detect.rs

/// CB-124: Enforce industry-standard coverage thresholds
pub fn detect_cb124_low_coverage_threshold(project_path: &Path) -> Vec<CbViolation> {
    const MINIMUM: f64 = 80.0;
    // Parse CI configs for coverage thresholds
    // Check: .github/workflows/*.yml, .gitlab-ci.yml, codecov.yml
    // Also check: .pmat-metrics.toml [coverage] threshold
}
```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-124-A (CI threshold <80%) | Warning | Industry standard violation |
| CB-124-B (PMAT config <80%) | Warning | Local override too low |

**Fix**: Raise threshold to 80%, or use ratchet approach (never decrease).

### 3.16 CB-125: Coverage Exclusion Gaming [P0 CRITICAL] (NEW - Coverage Quality)

**Justification**: [COV-003] Inozemtseva & Holmes (2014) showed coverage is not strongly correlated with test suite effectiveness when exclusions inflate metrics. [GAME-001] Popper's falsification principle: excluding code from coverage measurement is unfalsifiable—it hides defects rather than proving quality.

**Problem Statement**: Excessive `--ignore-filename-regex` patterns in Makefiles or coverage configs artificially inflate coverage percentages without improving actual test quality. This is a form of "coverage gaming" that violates the Toyota Way principle of Genchi Genbutsu (go and see reality).

**Source Evidence** (pmat Makefile):
```makefile
# Anti-pattern: 50+ exclusion patterns hiding >50% of codebase
COVERAGE_EXCLUDE := --ignore-filename-regex='(/tests/|/cli/|/mcp/|/agents/|...'
```

**Detection Patterns**:
```rust
/// CB-125: Detect coverage exclusion gaming
/// Thresholds based on [GAME-002] Google testing research: >20% exclusion suspicious
pub fn detect_cb125_coverage_exclusion_gaming(project_path: &Path) -> Vec<CbViolation> {
    const MAX_EXCLUSION_PATTERNS: usize = 10;  // Per [GAME-002]
    const MAX_EXCLUSION_LOC_PERCENT: f64 = 20.0;  // >20% excluded = gaming

    // Parse: Makefile, .cargo/config.toml, tarpaulin.toml, codecov.yml
    // Count: --ignore-filename-regex, --exclude, exclude patterns
    // Estimate: LOC excluded vs total LOC
}
```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-125-A (>10 exclusion patterns) | Warning | Complexity suggests gaming |
| CB-125-B (>20% LOC excluded) | Error | Significant coverage blind spot |
| CB-125-C (>50% LOC excluded) | Critical | Coverage metric meaningless |

**Falsification Test**:
> **Hypothesis L (Exclusion Gaming)**: CB-125 detects when coverage exclusions exceed 20% of codebase LOC.
> **Falsification Strategy**: Create Makefile with varying exclusion counts (5, 15, 30 patterns). If 30-pattern exclusion not flagged as Error, hypothesis is falsified.

**Fix**:
1. Reduce exclusions to genuinely untestable code (binary entry points only)
2. Document reason for each exclusion
3. Set exclusion budget: ≤20% of LOC

---

### 3.17 CB-126: Slow Test Detection [P1 HIGH] (NEW - Test Performance)

**Justification**: [SLOW-001] Luo et al. (2014) found slow tests cause developers to skip test runs, reducing defect detection. [SLOW-002] Google's TAP system (Memon et al. 2017) enforces <5s per test for Tier 1 feedback. [SLOW-003] certeza Tiered TDD-X: Tier 1 (ON-SAVE) requires sub-second feedback for flow state.

**Problem Statement**: Individual tests taking >5 seconds destroy developer flow and encourage test skipping. Property-based tests without iteration limits are especially problematic.

**Source Evidence** (pmat test output):
```
test quality_proxy_property_tests::test_xxx ... ok (79.234s)  # WAY too slow!
```

**Detection Patterns**:
```rust
/// CB-126: Detect slow tests that violate Tier 1 feedback requirements
/// Thresholds per [SLOW-002] Google TAP and [SLOW-003] certeza TDD-X
pub fn detect_cb126_slow_tests(project_path: &Path) -> Vec<CbViolation> {
    const TIER1_MAX_SECONDS: f64 = 5.0;   // Per Google TAP
    const TIER2_MAX_SECONDS: f64 = 60.0;  // Acceptable for ON-COMMIT
    const CRITICAL_SECONDS: f64 = 300.0;  // 5 min = test suite killer

    // Parse: cargo test output, nextest timing, proptest config
    // Check: PROPTEST_CASES not set (unbounded iterations)
    // Check: QUICKCHECK_TESTS not set (unbounded iterations)
}
```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-126-A (test >5s) | Warning | Violates Tier 1 requirement |
| CB-126-B (test >60s) | Error | Blocks commit workflow |
| CB-126-C (test >300s) | Critical | Suite unusable for TDD |
| CB-126-D (unbounded proptest) | Warning | PROPTEST_CASES not set |

**Falsification Test**:
> **Hypothesis M (Slow Tests)**: CB-126 detects tests exceeding Tier 1 threshold (5s).
> **Falsification Strategy**: Create test with `thread::sleep(Duration::from_secs(10))`. If not flagged as Warning, hypothesis is falsified.

**Fix**:
1. Set `PROPTEST_CASES=100` for Tier 1, `PROPTEST_CASES=1000` for Tier 2
2. Use `#[ignore]` with documented reason for slow integration tests
3. Split slow tests into separate `--ignored` suite for Tier 3

---

### 3.18 CB-127: Slow Coverage Detection [P1 HIGH] (NEW - Coverage Performance)

**Justification**: [PERF-001] certeza spec establishes coverage analysis budget: <2 minutes for Tier 2 (ON-COMMIT). [PERF-002] Google scale testing (Memon et al. 2017): slow feedback loops cause 10-100x productivity loss. [PERF-003] Toyota Way Muda (waste elimination): waiting is the worst form of waste.

**Problem Statement**: Coverage runs exceeding 10 minutes discourage regular measurement, leading to coverage regression. Common causes: nextest profraw explosion (1 file per test), unbounded property tests, missing `--lib` flag.

**Source Evidence** (pmat coverage timing):
```
# Anti-pattern: nextest creates 14,000+ profraw files
# Merge takes hours, making coverage impractical
```

**Detection Patterns**:
```rust
/// CB-127: Detect coverage configurations that cause slow execution
/// Thresholds per [PERF-001] certeza and [PERF-002] Google research
pub fn detect_cb127_slow_coverage(project_path: &Path) -> Vec<CbViolation> {
    const TIER2_MAX_MINUTES: f64 = 10.0;   // Max for ON-COMMIT
    const WARNING_MINUTES: f64 = 5.0;      // Target for good DX

    // Detect anti-patterns:
    // 1. cargo-nextest with llvm-cov (profraw explosion)
    // 2. Missing PROPTEST_CASES in coverage target
    // 3. Missing --lib flag (includes slow integration tests)
    // 4. Sequential shards instead of parallel
}
```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-127-A (nextest + llvm-cov) | Error | Known profraw explosion issue |
| CB-127-B (no PROPTEST_CASES) | Warning | Unbounded iterations in coverage |
| CB-127-C (coverage >10min) | Error | Exceeds Tier 2 budget |
| CB-127-D (coverage >30min) | Critical | Coverage unusable |

**Falsification Test**:
> **Hypothesis N (Slow Coverage)**: CB-127 detects coverage configurations that cause >10 minute execution.
> **Falsification Strategy**: Create Makefile with `cargo llvm-cov nextest` (known slow). If not flagged as Error, hypothesis is falsified.

**Fix**:
1. Use `cargo llvm-cov test` instead of nextest (1 profraw per binary, not per test)
2. Set `PROPTEST_CASES=2 QUICKCHECK_TESTS=2` for coverage runs
3. Use `--lib` to exclude slow integration tests from coverage
4. Target: <5 minutes for `make coverage`

### 3.19 CB-128: Dead Code Detection & TDG Integration [P0 CRITICAL] (NEW - v2.3)

**Justification**: [DEAD-001] Boomsma et al. (2012) "Dead Code Elimination in Practice": Dead code inflates maintenance costs by 15-30% and reduces comprehension. [DEAD-002] Romano & Pinzger (2011): Unreferenced code correlates with bug introduction. [DEAD-003] Toyota Way Muda: Dead code is pure waste - adds no value, increases cognitive load.

**Problem Statement**: `pmat analyze dead-code` reports 0% dead code, but manual inspection and rustc `#[warn(dead_code)]` reveal significant unreachable code. Dead code:
1. **Inflates coverage denominators**: Unreachable code counted in TOTAL but never executed
2. **Hides technical debt**: Dead functions accumulate without visibility
3. **Not in TDG scoring**: TDG has complexity, churn, coupling, duplication, domain_risk - but NOT dead_code
4. **Detection is broken**: Current analyzer uses AST-based reference tracking that misses many cases

**Source Evidence** (pmat dogfooding):
```bash
# Current detection shows 0% - clearly broken
$ pmat analyze dead-code --path . --format json | jq '.summary'
{
  "total_files_analyzed": 8309,
  "files_with_dead_code": 0,
  "total_dead_lines": 0,
  "dead_percentage": 0
}

# But there are 353 #[allow(dead_code)] attributes suppressing warnings!
$ grep -r "#\[allow(dead_code)\]" src/ | wc -l
353

# rustc won't report these because they're explicitly suppressed
# This is the PRIMARY source of hidden dead code
```

**Root Cause Analysis (Five Whys)**:
1. Why is dead code reporting 0%? → rustc warnings suppressed by `#[allow(dead_code)]`
2. Why are there 353 suppression attributes? → Developers add them to silence warnings
3. Why do developers silence warnings? → Easier than removing dead code
4. Why not remove dead code? → No visibility/enforcement mechanism
5. Why no enforcement? → Dead code not part of TDG/comply until now

**Proposed Solution: Four-Layer Detection**:

```rust
/// CB-128: Dead Code Detection with Setup/Teardown Validation
///
/// Four detection layers with decreasing accuracy/increasing coverage:
/// 1. SUPPRESSION_SCAN: Detect #[allow(dead_code)] attributes (100% accurate, finds hidden debt)
/// 2. COMPILER_LINT: Use rustc/clippy dead_code warnings (100% accurate for unsuppressed Rust)
/// 3. REFERENCE_GRAPH: Cross-file reference analysis via AST (90% accurate)
/// 4. HEURISTIC: Pattern-based detection (70% accurate, catches edge cases)

#[derive(Debug, Clone, Copy, PartialEq, Eq)]
pub enum DeadCodeDetectionMethod {
    /// Tier 1: Compiler lint output (rustc --emit=metadata with deny(dead_code))
    CompilerLint,
    /// Tier 2: Reference graph analysis (existing DeadCodeAnalyzer)
    ReferenceGraph,
    /// Tier 3: Heuristic patterns (unused test helpers, commented imports)
    Heuristic,
}

/// Dead code as TDG component (6th dimension)
pub struct TDGComponentsV2 {
    pub complexity: f64,
    pub churn: f64,
    pub coupling: f64,
    pub domain_risk: f64,
    pub duplication: f64,
    pub dead_code: f64,  // NEW: 0.0-5.0 scale like others
}

/// CB-128 detection with setup/teardown calibration
pub fn detect_cb128_dead_code(project_path: &Path) -> Vec<CbViolation> {
    // Layer 1: Parse rustc JSON diagnostics (private dead code)
    let compiler_dead = detect_via_compiler(project_path);

    // Layer 2: Reference graph (existing analyzer)
    let graph_dead = detect_via_reference_graph(project_path);

    // Layer 3: Heuristic patterns
    let heuristic_dead = detect_via_heuristics(project_path);

    // Layer 4: Workspace-Aware Public Item Analysis (Finding 18)
    // Detects 'pub' items that are unused within the entire workspace context
    let public_dead = detect_via_workspace_analysis(project_path);

    // Merge with confidence scoring
    merge_dead_code_results(compiler_dead, graph_dead, heuristic_dead, public_dead)
}
```

**Workspace-Aware Strategy (Finding 18)**:
1.  **Scope**: For workspace crates (e.g., `server`, `client`), treat `pub` items as "internal public" unless marked `#[no_mangle]` or exported via `lib.rs`.
2.  **Analysis**: Build a workspace-wide call graph. If a `pub` function in crate A is not called by A, B, or C, it is "Zombie Public Code".
3.  **Heuristic**: If a `pub` item has 0 references in the entire codebase (grep check), flag as Warning (potential dead code).

**Setup/Teardown Calibration Method**:
```rust
/// Calibration: Inject known dead code, verify detection, then remove
/// This creates a "golden test" suite for dead code detection accuracy
#[cfg(test)]
mod dead_code_calibration {
    /// Setup: Create file with known dead functions
    fn setup_dead_code_fixture() -> TempDir {
        let dir = TempDir::new().unwrap();
        std::fs::write(dir.path().join("dead_fixture.rs"), r#"

```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-128-A (>20% dead code) | Critical | Major maintenance burden |
| CB-128-B (>10% dead code) | Error | Significant coverage inflation |
| CB-128-C (>5% dead code) | Warning | Cleanup recommended |
| CB-128-D (dead public API) | Error | Breaking change when removed |
| CB-128-E (dead test helpers) | Warning | Test maintenance overhead |

**TDG Integration**:
```rust
/// Updated TDG calculation with dead_code component
fn calculate_weighted_tdg_v2(components: &TDGComponentsV2) -> f64 {
    // Weights sum to 1.0, with dead_code taking 10% weight
    const WEIGHTS: TDGWeights = TDGWeights {
        complexity: 0.25,    // Was 0.30
        churn: 0.20,         // Was 0.25
        coupling: 0.15,      // Was 0.15
        domain_risk: 0.10,   // Was 0.15
        duplication: 0.10,   // Was 0.15
        dead_code: 0.20,     // NEW: High weight because it's pure waste
    };

    components.complexity * WEIGHTS.complexity
        + components.churn * WEIGHTS.churn
        + components.coupling * WEIGHTS.coupling
        + components.domain_risk * WEIGHTS.domain_risk
        + components.duplication * WEIGHTS.duplication
        + components.dead_code * WEIGHTS.dead_code
}
```

**Falsification Tests (20 points)**:
> **Hypothesis O (Dead Code Detection)**: CB-128 detects unreferenced functions with >95% precision.
> **Falsification Strategy**: Create fixture with 10 known-dead and 10 known-live functions. If precision <95%, hypothesis is falsified.

> **Hypothesis P (TDG Dead Code)**: Adding dead_code component changes TDG scores for files with dead code.
> **Falsification Strategy**: Compare TDG v1 vs v2 on file with known dead code. If scores identical, hypothesis is falsified.

> **Hypothesis Q (Coverage Deflation)**: Removing detected dead code increases coverage percentage.
> **Falsification Strategy**: Measure coverage before/after dead code removal. If coverage doesn't increase, hypothesis is falsified.

**Fix Implementation Plan**:
1. **Phase 1**: Compiler integration - parse `cargo check --message-format=json` for dead_code warnings
2. **Phase 2**: TDG integration - add dead_code as 6th component with 0.20 weight
3. **Phase 3**: Comply integration - CB-128 check with threshold-based severity
4. **Phase 4**: Dogfood - run on pmat, clean up detected dead code, measure coverage delta

### 3.20 CB-130: PII Detection [P0 CRITICAL] (NEW - v2.9)

**Justification**: Hardcoded secrets are a top security vulnerability (OWASP Top 10). PII leakage violates privacy regulations.

**Detection Strategy**:
1.  **Regex Scanning**: Known patterns for API keys (AWS, Stripe, OpenAI), emails, IP addresses, phone numbers.
2.  **Entropy Analysis**: High-entropy strings often indicate random tokens/keys.
3.  **Context Analysis**: Look for variable names like `password`, `secret`, `token`, `key`.

**Proposed Patterns**:
```rust
pub fn detect_cb130_pii(project_path: &Path) -> Vec<CbViolation> {
    let patterns = [
        // Secrets
        (r"AKIA[0-9A-Z]{16}", "CB-130-A", "AWS Access Key ID"),
        (r"sk_live_[0-9a-zA-Z]{24}", "CB-130-B", "Stripe Secret Key"),
        (r"sk-[a-zA-Z0-9]{48}", "CB-130-C", "OpenAI API Key"),
        // PII
        (r"\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b", "CB-130-D", "Email Address"),
        (r"\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b", "CB-130-E", "IPv4 Address"), // Simple check, careful with false positives
    ];
    // ... implementation details ...
}
```

**Severity Mapping**:
| Pattern | Severity | Rationale |
|---------|----------|-----------|
| CB-130-A/B/C (Cloud Keys) | Critical | Immediate security risk |
| CB-130-D (Email) | Warning | Privacy risk, potential spam target |
| CB-130-E (IP) | Warning | Disclosure of internal infrastructure |

### 3.21 CB-304: Dead Code Percentage Hardening (v2.8.3)

**Problem**: CB-304 was bypassed by two adversarial vectors discovered via Popperian falsification audit:

1. **Block Comment Blindness**: Code inside `/* ... */` block comments was invisible to the dead line counter, which only detected `//` line comments.
2. **Macro Rules Inflation**: `macro_rules!` blocks containing `fn` declarations inflated the total item count denominator, diluting the dead code percentage toward 0%.

**Fix 1 — Block Comment Detection**:

```rust
/// Count lines inside `/* ... */` block comments that look like code.
fn count_block_comment_code_lines(lines: &[&str]) -> usize {
    // Track in_block state, accumulate lines with code markers
    // Only count blocks >= 2 lines (skip license headers, doc comments)
    // Code markers: "fn ", "let ", "if ", "return ", ";", "struct ", "impl ", "pub "
}
```

**Fix 2 — Macro Rules Exclusion**:

```rust
/// Track brace depth inside macro_rules! blocks.
/// Returns Some(depth) while inside a macro, None when outside.
fn update_macro_depth(trimmed: &str, current: Option<i32>) -> Option<i32>

/// count_dead_items now calls update_macro_depth per line,
/// skipping all content inside macro_rules! bodies.
```

**Rationale**: `macro_rules!` defines template code that only exists when invoked. An uninvoked macro's inner `fn` declarations never compile into the binary, so counting them inflates the denominator without corresponding dead items.

### 3.22 Provability Empty Source Guard (v2.8.3)

**Problem**: The lightweight provability analyzer scored empty or trivially empty functions as 1.0 (perfect provability). This is unsound — absence of hazards (no unsafe, no unwrap, no I/O) does not imply provability when there is nothing to prove.

**Attack Vectors**:
- **Empty Shell**: 50 empty `fn f() {}` functions each scored 1.0
- **Nonexistent File**: FunctionIds pointing to missing files scored 1.0 (empty string → no hazards detected)

**Fix**: Guard at top of `analyze_source_patterns`:

```rust
// Guard: empty/trivial source or empty function body → insufficient evidence
let body = source.split('{').nth(1).unwrap_or("");
let has_statements = body.contains(';') || body.contains("let ")
    || body.contains("return ") || body.contains("if ")
    || body.contains("match ") || body.contains("for ");
if source.trim().is_empty() || source.trim().len() < 5 || !has_statements {
    return PropertyDomain {
        nullability: NullabilityLattice::MaybeNull,
        bounds: IntervalLattice { lower: None, upper: None },
        aliasing: AliasLattice::MayAlias,
        purity: PurityLattice::Top,
    };
}
```

This produces a confidence score of 0.20 (low) for empty functions, correctly reflecting insufficient evidence.

### 3.23 Muda Waste Score Weight Specification (v2.8.3)

**Problem**: Inventory (SATD) weight was 10%, allowing crates with 500+ stale TODO/FIXME/HACK markers to score 14/100 ("Lean") — falsely passing quality gates.

**Updated Weight Distribution**:

| Waste Type | Weight | Rationale |
|------------|--------|-----------|
| **Defects** | 25% | Bugs requiring rework — highest direct cost |
| **Inventory** | 20% | Stale SATD accumulation — primary signal of unmaintained code |
| **Over-processing** | 15% | Overcomplicated algorithms |
| **Overproduction** | 15% | Dead code, unused features |
| **Waiting** | 15% | Slow tests blocking CI |
| **Motion** | 5% | Developer context switching |
| **Transport** | 5% | Excessive data copying |

**Formula**:
```rust
let total_score = (defects * 0.25)
    + (inventory * 0.20)
    + (over_processing * 0.15)
    + (overproduction * 0.15)
    + (waiting * 0.15)
    + (motion * 0.05)
    + (transport * 0.05);
```

**Evidence**: With 500 TODOs, Inventory scores 100/100 → contributes 20 points. Previous 10% weight contributed only 10 points, masking the waste.

## 5. 175-Point Popperian Falsification Suite

### 5.1 Philosophy

Per Karl Popper's *The Logic of Scientific Discovery* (1934) [POPPER-001], scientific theories are distinguished by their falsifiability. Each compliance check is a hypothesis that can be tested. Per *Conjectures and Refutations* (1963) [POPPER-002], progress occurs through bold conjectures and severe refutation attempts.

> **Hypothesis A (Detection)**: CB-050 correctly identifies all code-level stubs without false positives.
> **Falsification Strategy**: Construct adversarial inputs (obfuscated macros, weird spacing) that should trigger detection but don't.
>
> **Hypothesis B (Regex Sufficiency)**: Regular expressions are sufficient to detect GPU barriers/branching (CB-060) with >90% precision, without requiring a full AST parser.
> **Falsification Strategy**: Run regex checks against a parser-based ground truth. If regex misses >10% of cases found by a parser, Hypothesis B is falsified, and we must pivot to `syn`/`tree-sitter`.
>
> **Hypothesis C (Wild Stability)**: The checks are stable on unseen "Wild" code.
> **Falsification Strategy**: Run checks against the `rust-lang/cargo` or `tokio-rs/tokio` repositories. If >100 false positives occur, the specification is falsified.
>
> **Hypothesis D (Unwrap Context)**: CB-070 can distinguish intentional `.unwrap()` from accidental without excessive false positives.
> **Falsification Strategy**: Run against batuta/trueno codebase. If >20% of flagged `.unwrap()` calls are intentional (have UNWRAP: comments or prior checks), hypothesis is falsified.
>
> **Hypothesis E (Drift Detection)**: CB-080 accurately detects version incompatibilities without blocking valid combinations.
> **Falsification Strategy**: Run against known-good workspace with multiple batuta stack crates. If any false incompatibilities flagged, hypothesis is falsified.
>
> **Hypothesis F (Flaky Precision)**: CB-090 timing pattern detection has >80% precision for actual flaky tests.
> **Falsification Strategy**: Run against trueno's commit history. If pattern detection doesn't catch 80%+ of the 7 known flaky test fixes, hypothesis is falsified.
>
> **Hypothesis G (NaN Detection)**: CB-120 detects all NaN-unsafe `partial_cmp().unwrap()` patterns without flagging safe alternatives.
> **Falsification Strategy**: Run against OIP codebase. Must detect all 10 instances in ml.rs, imbalance.rs, classifier.rs. If any `total_cmp()` or `unwrap_or()` flagged as false positive, hypothesis is falsified.
>
> **Hypothesis H (Lock Safety)**: CB-121 detects lock poisoning vulnerabilities without flagging `parking_lot` or proper handlers.
> **Falsification Strategy**: Run against OIP codebase. Must detect all 10 instances in git.rs. If `unwrap_or_else(|e| e.into_inner())` flagged, hypothesis is falsified.
>
> **Hypothesis I (Serde Precision)**: CB-122 detects unsafe deserialization without flagging `?` operator usage.
> **Falsification Strategy**: Run against OIP codebase. Must detect all 15+ instances in tarantula.rs, github.rs, citl.rs. If any `serde_json::from_str(s)?` flagged, hypothesis is falsified.
>
> **Hypothesis J (Ignore Docs)**: CB-123 only flags undocumented `#[ignore]` without flagging properly documented ones.
> **Falsification Strategy**: Construct test with `#[ignore = "reason"]` and `#[ignore] // reason`. Both must pass. Bare `#[ignore]` must fail.
>
> **Hypothesis K (Coverage Threshold)**: CB-124 correctly identifies low coverage thresholds across different config formats.
> **Falsification Strategy**: Test against tarpaulin.toml, llvm-cov config, and CI scripts. If 58% threshold not flagged as Error, hypothesis is falsified.

| Test coverage (v2.0) | 100% | All 150 falsification tests pass |

#### New Metrics (v2.1 - OIP Tarantula)

| Metric | Target | Measurement |
|--------|--------|-------------|
| NaN-unsafe detection recall | 100% | All `partial_cmp().unwrap()` patterns caught |
| NaN-unsafe detection precision | >95% | No false positives on safe patterns (`total_cmp`, `unwrap_or`) |

### 7.2 Qualitative Criteria

- [ ] All peer-reviewed citations verified and accessible (28 citations)
- [ ] Work tickets tracked in pmat roadmap (25 tickets: COMPLY-001 through COMPLY-025)
- [ ] Documentation updated (USER_GUIDE.md, CLAUDE.md)
- [ ] No regressions in existing comply checks
- [ ] Suppression format approved by team
- [ ] Sovereign stack repos (trueno, aprender, realizar, batuta) pass new checks
- [ ] OIP (organizational-intelligence-plugin) Tarantula faults validated by new checks

### 7.3 Toyota Way Validation

- **Genchi Genbutsu**: Solutions derived from actual issue analysis (#32, #37, #69, #77, #131) AND bug fix history across sovereign stack
- **Jidoka**: Automated detection with clear failure modes; stop the line on critical issues
- **Kaizen**: Incremental rollout with Phase 1-5 gates
- **Hansei**: Retrospective analysis of bug fix patterns informs new checks
- **Respect for People**: Suppression mechanism respects developer judgment; context-aware filtering

### 7.4 Catastrophic Failure Protocol (Popperian Guardrails)

If any of the following conditions are met during Phase 1-4, the implementation is considered **Falsified** and must be immediately rolled back for re-theorizing:

1.  **False Positive Explosion**: If > 5% of "violations" in the first 50 files scanned are valid code (not debt), the pattern logic is scientifically invalid.
2.  **Performance Regression**: If `pmat comply` execution time increases by > 15% (validated by `hyperfine`), the architectural hypothesis is rejected.
3.  **Suppression Fatigue**: If users suppress > 20% of warnings in the first week, the check lacks "Empirical Utility" and must be disabled.
4.  **Unwrap False Positives**: If >30% of CB-070 warnings are for intentional `.unwrap()` calls (with prior checks or documented reasons), the context-filtering hypothesis is falsified.
5.  **Flaky Pattern Misses**: If CB-090 fails to catch 4 of the 7 known trueno flaky test patterns, the detection strategy is falsified.
6.  **Stack Compatibility False Alarms**: If CB-080 flags any known-good batuta stack version combination, the compatibility matrix is falsified.
7.  **NaN Safety False Positives**: If CB-120 flags >10% of safe float comparisons (e.g., `total_cmp`), the regex pattern is falsified.
8.  **Lock Poisoning Noise**: If CB-121 flags `parking_lot` mutexes (which don't poison) or properly handled results, the check logic is falsified.
9.  **Serde Valid Usage**: If CB-122 flags >20% of `serde_json::from_str` calls where the schema is guaranteed internal (e.g., config files bundled with binary), the "always unsafe" hypothesis is rejected.

## 8. Batuta RAG Oracle Integration (v2.4 - NEW)

**Status:** Proposed
**Added:** 2026-02-01
**Rationale:** Leverage the batuta RAG oracle's indexed sovereign stack documentation to provide contextual suggestions, enforce cross-project patterns, and improve developer experience when violations are detected.

### 8.1 Overview

The batuta CLI provides a RAG (Retrieval-Augmented Generation) oracle that indexes documentation from the entire sovereign AI stack:
- CLAUDE.md files from all stack components
- Specification documents (docs/specifications/*.md)
- mdBook documentation (book/src/**/*.md)
- Ground truth corpora (Python, MLOps patterns)

Integration with `pmat comply` enables:
1. Contextual fix suggestions when violations are detected
2. Smart project initialization based on project type
3. Explanation of why each check matters with real examples
4. Cross-project pattern enforcement for stack consistency
5. Drift-aware dependency recommendations

### 8.2 Proposed Features

#### 8.2.1 CB-200: Contextual Fix Suggestions

**Problem:** When `pmat comply check` detects a violation, developers must search documentation manually for the correct fix pattern.

**Solution:** Query the batuta oracle for contextual fixes based on the violation code and message.

**Implementation:**
```rust
// In comply check handler (src/cli/handlers/comply_handlers/check_handlers.rs)
fn suggest_fix_from_oracle(violation: &ComplianceViolation) -> Option<Vec<OracleSuggestion>> {
    let query = format!(
        "How to fix {} in Rust: {}",
        violation.code, violation.message
    );

    // Query batuta oracle (shell out or library integration)

}
```

**Quality Guardrails (Ref: [RAG-002]):**
1. **Citation Requirement:** Every suggestion MUST include a valid file path (`source_file`) existing in the current stack index. Suggestions without citations are discarded (Hallucination Filter).
2. **Confidence Threshold:** Only display results with retrieval score > 0.75.
3. **Negative Constraint:** Explicitly filter out "I suggest checking online" or "As an AI..." boilerplate.

**Example Output:**
```

#### 8.2.2 CB-201: Smart Project Initialization

**Problem:** New projects must manually configure `.pmat-gates.toml` quality thresholds without guidance on what's appropriate for their project type.

**Solution:** Query oracle to bootstrap quality gates based on detected project characteristics.

**Implementation:**
```rust
// In pmat comply init --smart
fn smart_init_gates(project_path: &Path) -> Result<PmatGatesConfig> {
    let project_type = detect_project_type(project_path)?;
    // e.g., "ml-library", "cli-tool", "web-service", "systems-library"

    let query = format!(
        "Recommended pmat quality gates for {} Rust project thresholds coverage complexity",
        project_type
    );

    let recommendations = batuta_oracle_query(&query)?;

    // Parse oracle response into gate configuration
    generate_gates_from_recommendations(project_type, recommendations)
}
```

**Example:**
```bash
$ pmat comply init --smart

🔍 Detected project type: ML library (aprender-like)
📚 Querying batuta oracle for recommended gates...

Recommended .pmat-gates.toml:

[quality]
min_coverage_pct = 90.0          # ML libs need high coverage (aprender: 94%)
max_complexity = 15              # Lower threshold for numeric code
max_unsafe_blocks = 5            # Strict unsafe limits

[checks]
nan_safety = "error"             # CB-120: Critical for ML
float_comparison = "error"       # CB-201: No direct f64 == f64
mutation_score = 80              # High mutation coverage

[dependencies]
prefer_sovereign = true          # Prefer aprender/trueno over external

Apply these settings? [Y/n]
```

#### 8.2.3 CB-202: Explain Mode with Stack Context

**Problem:** Developers see violation codes (CB-xxx) but don't understand why the check exists or its real-world impact.

**Solution:** Add `--explain` flag that queries oracle for rationale and real examples from the stack.

**Implementation:**
```rust
// In pmat comply check --explain
fn explain_violation(violation: &ComplianceViolation) -> Result<Explanation> {
    let query = format!(
        "Why is {} important? Real examples of bugs caused by {} in Rust projects",
        violation.code, violation.pattern
    );

    let context = batuta_oracle_query(&query)?;

    Ok(Explanation {
        code: violation.code.clone(),
        rationale: context.top_result().content,
        source: context.top_result().document_id,
        real_example: extract_example(&context),
    })
}
```

**Example Output:**
```bash
$ pmat comply check --explain

⚠ CB-125: Coverage exclusion gaming detected (15 patterns hiding 23% LOC)

  📚 Why this matters:
     "Coverage exclusion patterns that hide >20% of LOC indicate technical
     debt hiding rather than legitimate test exclusions. In trueno v0.12,
     40% exclusions masked a critical memory leak in the SIMD path that
     wasn't caught until production. The fix required 3 weeks of debugging."

#### 8.2.4 CB-203: Cross-Project Pattern Enforcement

**Problem:** Different projects in the sovereign stack may drift into inconsistent patterns (error handling, logging, testing conventions).

**Solution:** Query oracle for patterns used across the stack and enforce consistency.

**Implementation:**
```rust
// In pmat comply check (new check category)
fn check_stack_pattern_consistency(project_path: &Path) -> Vec<ComplianceViolation> {
    let mut violations = vec![];

    // Query oracle for stack-wide conventions
    let conventions = batuta_oracle_query(
        "error handling patterns sovereign stack thiserror anyhow convention"
    )?;

    // Check: Libraries should use thiserror, binaries can use anyhow
    if is_library(project_path) && uses_anyhow_in_lib(project_path) {
        if conventions.consensus.contains("thiserror for libraries") {
            violations.push(ComplianceViolation {
                code: "CB-203".into(),
                severity: Severity::Warning,
                message: "Stack convention: use thiserror for library error types, not anyhow".into(),
                suggestion: Some("See aprender/src/error.rs for example".into()),
            });
        }
    }

    // Check: Logging convention (tracing vs log)
    // Check: Test organization (#[cfg(test)] vs tests/)
    // Check: Documentation style (rustdoc conventions)

    violations
}
```

**Enforced Patterns:**
| Pattern | Library Convention | Binary Convention | Source |
|---------|-------------------|-------------------|--------|
| Error handling | `thiserror` | `anyhow` | aprender, trueno |
| Logging | `tracing` | `tracing` | all stack |
| Async runtime | `tokio` | `tokio` | all stack |
| Serialization | `serde` + explicit formats | `serde_json` | all stack |
| Testing | `#[cfg(test)]` in-file | `tests/` directory | all stack |

#### 8.2.5 CB-204: Drift-Aware Dependency Recommendations

**Problem:** Projects may use outdated or non-sovereign dependencies when better alternatives exist in the stack.

**Solution:** Integrate oracle's stack knowledge to recommend dependency updates and sovereign alternatives.

**Implementation:**
```rust
// In pmat comply check --deps
fn check_dependencies_with_oracle(project_path: &Path) -> DependencyReport {
    let cargo_toml = read_cargo_toml(project_path)?;
    let mut report = DependencyReport::default();

    // Check for sovereign alternatives
    for dep in &cargo_toml.dependencies {
        let query = format!(
            "sovereign stack alternative to {} crate Rust",
            dep.name
        );

        if let Some(alternative) = batuta_oracle_query(&query)?.sovereign_alternative {
            report.suggestions.push(DependencySuggestion {
                current: dep.clone(),
                suggested: alternative.name,
                reason: alternative.rationale,
                perf_improvement: alternative.benchmark_delta,
            });
        }
    }

    // Check for version drift against stack
    let stack_versions = batuta_oracle_query("current sovereign stack versions")?;
    for dep in SOVEREIGN_DEPS {
        if let Some(current) = cargo_toml.get_version(dep) {
            if let Some(latest) = stack_versions.get(dep) {
                if current < latest {
                    report.drift.push(VersionDrift {
                        package: dep.into(),
                        current: current.clone(),
                        latest: latest.clone(),
                        changelog_note: get_changelog_note(dep, current, latest),
                    });
                }
            }
        }
    }

    report
}
```

**Example Output:**
```bash
$ pmat comply check --deps

### 8.5 Work Tickets Summary

| Ticket | Feature | Priority | Effort |
|--------|---------|----------|--------|
| COMPLY-026 | CB-200: Contextual Fix Suggestions | P0 | Medium |
| COMPLY-027 | CB-201: Smart Project Init | P2 | Medium |
| COMPLY-028 | CB-202: Explain Mode | P0 | Low |
| COMPLY-029 | CB-203: Cross-Project Patterns | P2 | High |
| COMPLY-030 | CB-204: Drift-Aware Deps | P1 | Low |

### 8.6 Falsification Tests (T-176 to T-180)

These tests follow the **Popperian Falsification Principle**: we do not prove the Oracle works; we try to prove it fails (hallucinates, retrieves garbage, or misguides). If it survives these adversarial attacks, it is deemed robust.

| Test ID | Target | Falsification Protocol (Adversarial Attack) | Failure Mode (Refutation) | Pass Criteria |
|---------|--------|---------------------------------------------|---------------------------|---------------|
| **T-176** | CB-200: Fix Suggestions | **Attack:** Inject a nonsense violation code (e.g., `CB-999: QuantumFluxOverflow`) with a standard error message. | **Failure:** Oracle confidently suggests a fix (>0.5 confidence) or invents a non-existent documentation link. | Oracle returns "Unknown Violation" or low confidence (<0.2) with generic fallback. |
| **T-177** | CB-201: Smart Init | **Attack:** Run on an empty directory or a file with mixed languages (Rust + Python + JS) and contradictory config files. | **Failure:** Oracle generates a config that contradicts itself (e.g., `python_version` in a Rust project) or crashes. | Oracle identifies "Mixed/Unknown Project" and asks for manual clarification. |
| **T-178** | CB-202: Explain Mode | **Attack:** Request explanation for a real error but disconnect the network/vector DB (force cache miss). | **Failure:** Oracle returns a "best guess" that is factually wrong (hallucination) instead of an error or cached generic. | Oracle explicitly states "Offline - Explanation Unavailable" or returns verified static fallback. |
| **T-179** | CB-203: Patterns | **Attack:** Create a file matching *exactly* 50% of the "Library" pattern and 50% of the "Binary" pattern. | **Failure:** Oracle flips randomly between enforcing "thiserror" and "anyhow" on subsequent runs (nondeterminism). | Oracle consistently classifies as "Hybrid" or flags ambiguity requiring human override. |
| **T-180** | CB-204: Deps | **Attack:** Mock a "newer" version of `aprender` (v99.0.0) in the oracle index that contains breaking changes. | **Failure:** Oracle blindly recommends upgrading to v99.0.0 without checking compatibility constraints. | Oracle respects semantic versioning constraints and warns about "Unstable/Future" versions. |

### 8.7 Dependencies

- `batuta >= 0.6.2` with RAG oracle support
- RAG index built: `batuta oracle --rag-index`
- Network access for initial index build (cached locally after)

### 8.8 Rollout Plan

| Phase | Milestone | Timeline |
|-------|-----------|----------|
| Phase 1 | CB-202 (Explain) + CB-200 (Suggestions) | Week 1 |
| Phase 2 | CB-204 (Deps) | Week 2 |
| Phase 3 | CB-201 (Smart Init) + CB-203 (Patterns) | Week 3-4 |
| Phase 4 | SCORE-001 to SCORE-004 (rust-project-score) | Week 5-6 |

### 8.9 Integration with rust-project-score

The batuta RAG oracle should also enhance `pmat rust-project-score` to provide contextual scoring and recommendations.

#### 8.9.1 Score Explanation Mode

**Command:** `pmat rust-project-score --explain`

When a score component is below target, query oracle for:
1. Why this metric matters (with real incidents)
2. How top-scoring sovereign stack projects achieve high scores
3. Specific actionable steps to improve

**Example Output:**
```
📊 Rust Project Score: 78/106

Category Breakdown:
  Rust Tooling (21/25):
    ⚠ Clippy: 18/20 (-2 for 3 correctness warnings)
      💡 Oracle: "trueno achieved 20/20 by adding #![deny(clippy::correctness)]
         to lib.rs - catches subtle bugs like lossy float casts"

  Code Quality (19/26):
    ⚠ Mutation Testing: 5/8 (62% mutation score, target 80%)
      💡 Oracle: "aprender reaches 85% by focusing mutants on numeric code.
         See: aprender/tests/mutation_targets.rs for priority patterns"

    ⚠ Unsafe Code: 6/9 (3 undocumented unsafe blocks)
      💡 Oracle: "Document with // SAFETY: comment per trueno convention.
         Example: trueno/src/simd/avx.rs:42"

  Dependencies (8/12):
    ⚠ Non-Sovereign: -4 (using petgraph, ndarray)
      💡 Oracle: "Consider trueno-graph (3x faster PageRank) and
         aprender::tensor (zero-copy SIMD interop)"
```

#### 8.9.2 Sovereign Stack Bonus Scoring

Add bonus points for using sovereign stack components:

| Dependency | Replaces | Bonus | Rationale |
|------------|----------|-------|-----------|
| aprender | linfa, smartcore | +2 | Pure Rust, TDG 94/100, zero deps |
| trueno | ndarray | +2 | SIMD-first, GPU support |
| trueno-graph | petgraph | +1 | CSR native, PageRank optimized |
| trueno-rag | qdrant, milvus | +1 | Pure Rust, no external services |
| trueno-db | polars (partial) | +1 | Columnar storage, analytics |
| renacer | ad-hoc testing | +1 | Golden tracing, deterministic |
| presentar-core | ratatui | +1 | Jidoka verification, zero-alloc |

**Maximum Sovereign Bonus:** +10 points (extends 106 → 116 total)

**Implementation:**
```rust
fn score_dependency_sovereignty(cargo_toml: &CargoToml) -> SovereigntyScore {
    let sovereign_map = batuta_oracle_query("sovereign stack dependency mapping")?;

    let mut bonus = 0;
    let mut suggestions = vec![];

    for dep in &cargo_toml.dependencies {
        if sovereign_map.is_sovereign(&dep.name) {
            bonus += sovereign_map.bonus_for(&dep.name);
        } else if let Some(alt) = sovereign_map.alternative_for(&dep.name) {
            suggestions.push(SovereignSuggestion {
                current: dep.name.clone(),
                sovereign: alt.name,
                bonus: alt.bonus,
                migration_guide: alt.docs_url,
            });
        }
    }

    SovereigntyScore { bonus, suggestions }
}
```

#### 8.9.3 Project Type Calibration

Query oracle to calibrate scoring thresholds based on project type:

| Project Type | Coverage | Mutation | Complexity | Unsafe Docs | Example |
|--------------|----------|----------|------------|-------------|---------|
| ML Library | 90% | 80% | 15 | Required | aprender |
| SIMD/GPU Lib | 85% | 75% | 15 | Required | trueno |
| CLI Tool | 80% | 60% | 20 | Optional | batuta |
| Web Service | 85% | 70% | 20 | Optional | - |
| Systems Lib | 85% | 75% | 12 | Required | trueno-db |

**Auto-detection:**
```rust
fn detect_and_calibrate(project_path: &Path) -> ScoringThresholds {
    let project_type = detect_project_type(project_path);
    // Check for: #![no_std], SIMD intrinsics, async runtime, ML deps, etc.

    let calibration = batuta_oracle_query(&format!(
        "rust-project-score calibration {} sovereign stack",
        project_type
    ))?;

    ScoringThresholds::from_oracle(calibration)
}
```

### 8.10 pmat work Integration - Compliance Convergence

**Core Principle:** All development work funnels through `pmat comply` as the mandatory quality gate. Work CANNOT complete unless ALL quality gates pass.

**Workflow:**
```
START → DEV → REVIEW → DONE
  ↓       ↓      ↓       ↓
comply  comply comply  comply
(warn)  (watch) (check) (BLOCK)
```

#### 8.10.1 Convergence Targets (Zero Tolerance)

`pmat work done` automatically converges to these targets:

| Gate | Target | Enforcement |
|------|--------|-------------|
| **Coverage** | 95% overall | BLOCK if below |
| **Per-file Coverage** | 95% each file | BLOCK if any file below |
| **SATD** | Zero new | BLOCK if new TODO/FIXME/HACK added |
| **Dead Code** | Zero new | BLOCK if new unreachable code |
| **Lint** | `make lint` passes | BLOCK on lint failure |
| **Violations** | No new CB-xxx | BLOCK on new violations |

#### 8.10.2 O(1) Completion (CRITICAL)

**Problem:** Running `cargo build --examples`, `cargo deny check`, `make lint`, `make coverage` during `pmat work complete` takes 5-15 minutes, defeating the purpose of fast feedback.

**Solution:** All checks read from **cached metrics** populated by pre-commit hooks or CI. Completion is O(1) - just JSON reads. Performance improved from 5-15 minutes to **~2.2 seconds**.

**Staleness Policy:**
- **Cache > 1 hour**: WARNING (proceed with caution)
- **Cache > 24 hours**: BLOCK (must run `make lint` or relevant command first)
- **No cache**: BLOCK (must run checks first)

**Remaining slow operations (Future Optimization):**
- **File size check**: Currently walks 606+ files (O(N)). Should move to cached file manifest.
- **Gaming detector**: Scans files for exclusion patterns (O(N)). Should move to cached analysis result.

**Popperian Cache Audit Findings (v2.7.0):**

| Vector | Status | Fix Applied |
|--------|--------|-------------|
| **1.1 Time-Travel** | ✅ SURVIVED | N/A (Already robust) |
| **1.2 Empty Cache** | ✅ FIXED | Changed default from PASS to FAIL on missing cache |
| **2.1 Malformed JSON** | ✅ FIXED | Removed `unwrap_or(true)`, enforce "passed" field existence |
| **3.1 Big Data** | ✅ SURVIVED | Streaming parse handles large files efficiently |

**Risk Assessment:**
- **Race Conditions:** Low risk (local environment).
- **Integrity:** Mitigated by strict field validation (must have `passed: true`).

📋 Completing work item W-123: Add feature X

🔍 Reading cached metrics... (O(1) - 47ms)

  ✓ lint-status.json: PASSED (cached 12 min ago)
  ✓ coverage.json: 92.3% (cached 12 min ago)
  ✓ satd-count.json: 77 markers (cached 12 min ago)
  ✓ Detecting SATD...
  ✓ Detecting dead code...

❌ BLOCKED - Cannot complete work:

  Coverage violations:
    Overall: 92.3% (target: 95%) ❌
    Per-file below 95%:
      → src/new_module.rs: 0% coverage (23 lines) ❌
      → src/handler.rs: 87.2% coverage (needs +12 lines tested) ❌

  SATD violations (NEW markers introduced):
    → src/cache.rs:45: TODO: implement proper cache invalidation ❌
    → src/parser.rs:123: FIXME: handle edge case ❌

  Dead code violations (NEW unreachable code):
    → src/utils.rs: fn unused_helper() never called ❌
    → src/old_api.rs: entire module unreachable ❌

  NEW violations introduced (not in baseline):
    1. CB-121: Lock poisoning at src/cache.rs:89
    2. CB-127: Slow test detected (45s > 30s threshold)

  Lint status: PASSED ✓

## 9. Enhanced Theoretical Framework (v2.8 - NEW)

**Status:** Proposed
**Added:** 2026-02-01 (v2.8)
**Source:** Batuta Oracle & Sovereign AI Assurance Protocol

### 9.1 Three-Layer Operational Architecture

To align with the **Sovereign AI Assurance Protocol**, compliance is structured into three operational layers:

1.  **Layer 1 (Jidoka): Automated Quality Gates**
    *   **Tool:** `pmat comply check` (and `pmat work`)
    *   **Function:** Instant, blocking, automated checks.
    *   **Scope:** CB-050 through CB-128.
    *   **Principle:** Stop the line immediately on defect detection.

2.  **Layer 2 (Genchi Genbutsu): Evidence-Based Review**
    *   **Tool:** `pmat comply --review`
    *   **Function:** Human-in-the-loop verification of complex patterns.
    *   **Scope:** Architecture diagrams, design decisions, trade-off analysis.
    *   **Principle:** Go and see; verify facts personally.

3.  **Layer 3 (Governance): Audit Artifacts**
    *   **Tool:** `pmat comply --audit`
    *   **Function:** Immutable record generation for external validation.
    *   **Scope:** Release artifacts, SBOMs, falsification reports.
    *   **Principle:** Transparency and accountability.

### 9.2 Seven Wastes (Muda) in Code Quality

We map the Toyota Production System's "Seven Wastes" directly to code quality metrics to create the **Muda Waste Score (CB-300)**.

| Toyota Waste | Code Quality Equivalent | Detection Metric |
| :--- | :--- | :--- |
| **Overproduction** | Dead Code / Unused Features | `dead_code` analysis (CB-128) |
| **Waiting** | Slow Tests / Long Builds | Test execution time (CB-126, CB-127) |
| **Inventory** | Stale Branches / Old SATD | SATD age > 90 days (CB-050) |
| **Transport** | Excessive Data Copying | `.clone()` in hot loops (via `clippy`) |
| **Over-processing** | Complexity / Over-engineering | Cyclomatic Complexity > 15 |
| **Motion** | Context Switching / Sprawl | Dependency count / Graph depth |
| **Defects** | Bugs / Test Failures | Test failure rate / Panic counts |

**Implementation:** `pmat comply check --muda` calculates a "Waste Score" (lower is better).

### 9.3 Reproducibility Standards

Adopting NeurIPS/ICLR standards for ML/AI reproducibility.

**CB-301: Reproducibility Level Check**
*   **Bronze:** Code compiles + Dependencies pinned (`Cargo.lock`).
*   **Silver:** Deterministic seed control + Training data versioned (DVC/Git LFS).
*   **Gold:** Full pipeline containerized (Docker) + "Golden Trace" verification.

### 9.4 Golden Trace Validation

Integration with `renacer` for transpilers and distributed systems.

**CB-302: Golden Trace Drift**
*   **Concept:** Compare execution traces against a blessed "Golden Trace" to detect behavioral regression even if output looks correct.
*   **Source:** Batuta Oracle recipe `quality-golden-trace`.
*   **Check:** `renacer verify --trace golden.json` must pass.

### 9.5 Equation-Driven Development (EDD)

For simulation projects (using `simular` or `trueno-sim`).

**CB-303: EDD Compliance**
*   **Requirement:** Every core simulation function must reference a LaTeX equation in doc comments.
*   **Source:** Batuta Oracle recipe `quality-edd`.
*   **Check:** Regex scan for `$$ ... $$` or markdown math in public API docs.

### 9.6 Enhanced Checklist Format

All future checks must define:
1.  **Claim:** What property is being enforced?
2.  **Null Hypothesis:** "The system is compliant."
3.  **Falsification Test:** Specific attack to prove non-compliance.
4.  **Rejection Criteria:** Exact condition to fail the check.
5.  **TPS Principle:** Alignment (e.g., Jidoka, Poka-Yoke).
6.  **Evidence Required:** Log/Artifact proof.

### 9.7 Architectural Invariants

*   **YAML-First:** `.pmat.yaml` is the source of truth. (Migration from TOML pending for v3.0, currently TOML dominant).
*   **Zero False Positive Policy:** Any check with >5% false positive rate must be disabled or moved to "Warning" until fixed. 24-hour SLA to fix false positives.

### 9.8 New Work Tickets

| ID | Title | Priority | Effort |
| :--- | :--- | :--- | :--- |
| **COMPLY-040** | CB-300 Muda Waste Score | P2 | Medium |
| **COMPLY-041** | CB-301 Reproducibility Check | P2 | Medium |
| **COMPLY-042** | CB-302 Golden Trace Integration | P1 | High |
| **COMPLY-043** | CB-303 EDD Compliance | P3 | Low |
| **COMPLY-044** | YAML-first configuration | P1 | Medium |
| **COMPLY-045** | Three-layer CLI (`--review`, `--audit`) | P1 | High |

### 9.9 Falsification Tests (T-200 to T-204)

| Test ID | Target | Adversarial Protocol | Pass Criteria |
| :--- | :--- | :--- | :--- |
| **T-200** | CB-300 Muda | **Attack:** create a project with 1000 lines of dead code and 10s sleep in tests. | **Pass:** Muda Score > 80 (High Waste). |
| **T-201** | CB-301 Repro | **Attack:** delete `Cargo.lock` and running container. | **Pass:** Downgrade to "None" or "Bronze" status. |
| **T-202** | CB-302 Trace | **Attack:** alter random seed in `renacer` config but keep logic same. | **Pass:** Trace mismatch detected (butterfly effect). |
| **T-203** | CB-303 EDD | **Attack:** write a physics function with text description but no LaTeX. | **Pass:** Violation "Missing Mathematical Model". |
| **T-204** | Layer 3 Audit | **Attack:** run `--audit` on dirty git state. | **Pass:** Refuse to generate audit artifact (audit requires cleanliness). |

## 9. Enhanced Theoretical Framework (v2.8 - Batuta Oracle Integration)

*Insights from `batuta oracle --rag` and the Sovereign AI Assurance Protocol (popperian-falsification-checklist v2.2)*

### 9.1 Three-Layer Operational Architecture

Following the Sovereign AI Assurance Protocol, `pmat comply` should operate across three layers:

```
┌─────────────────────────────────────────────────────────────────┐

**TPS Principle Mapping**:

| Layer | TPS Principle | Application |
|-------|---------------|-------------|
| 1 | **Jidoka** | Automatic stop on quality violation |
| 2 | **Genchi Genbutsu** | Reviewer must "go and see" evidence |
| 3 | **Kaizen** | Every defect signals process failure |

### 9.2 Seven Wastes (Muda) in Code Quality

Adapted from Toyota Production System for `pmat comply` detection:

| Waste Type | Code Quality Manifestation | Detection (CB-XXX) |
|------------|---------------------------|-------------------|
| **Overproduction** | Dead code, unused features | CB-128, CB-304 |
| **Waiting** | Slow tests blocking CI | CB-126, CB-127 |
| **Transport** | Excessive data copying in hot paths | (Future: perf lint) |
| **Overprocessing** | Overcomplicated algorithms where simple suffices | Complexity checks |
| **Inventory** | Stale SATD markers accumulating | CB-050 |
| **Motion** | Developer context switching from flaky tests | CB-090 |
| **Defects** | Bugs requiring rework | All CB checks |

**Implemented Check (CB-300): Muda Waste Score**

```rust
/// CB-300: Aggregate waste score for project health
/// Weights: Defects 25%, Inventory 20%, Over-processing 15%,
///          Overproduction 15%, Waiting 15%, Motion 5%, Transport 5%
pub fn calculate_muda_score(project_path: &Path) -> MudaReport {
    let total_score = (defects * 0.25)
        + (inventory * 0.20)         // SATD markers (elevated v2.8.3)
        + (over_processing * 0.15)   // Complexity
        + (overproduction * 0.15)    // Dead code (CB-304)
        + (waiting * 0.15)           // Slow tests (CB-126)
        + (motion * 0.05)            // Flaky tests
        + (transport * 0.05);        // Clone density
    // ...
}
```

**Weight Rationale** (v2.8.3 — Popperian audit correction):
- Inventory elevated 10%→20%: 500 stale TODOs scored "Lean" at 10% weight, masking waste
- Over-processing/Overproduction reduced 20%→15% each to balance the total to 100%
- See §3.23 for full weight specification and evidence

### 9.3 Reproducibility Standards

Derived from NeurIPS/ICLR standards and Sovereign AI Assurance Protocol:

| Level | Requirements | pmat comply Check |
|-------|--------------|-------------------|
| **Bronze** | Code available | Always met (source repo) |
| **Silver** | Code + data + environment documented | Dockerfile exists, deps pinned |
| **Gold** | Third-party reproduction with single command | `make reproduce` works |

**Proposed Check (CB-301): Reproducibility Level**

```rust
/// CB-301: Verify reproducibility level
pub fn check_reproducibility(project_path: &Path) -> ReproducibilityLevel {
    let has_dockerfile = project_path.join("Dockerfile").exists();
    let has_lockfile = project_path.join("Cargo.lock").exists()
        || project_path.join("package-lock.json").exists();
    let has_make_reproduce = check_makefile_target(project_path, "reproduce");
    let has_random_seeds = check_for_seeded_rng(project_path);

    match (has_dockerfile, has_lockfile, has_make_reproduce, has_random_seeds) {
        (true, true, true, true) => ReproducibilityLevel::Gold,
        (true, true, _, _) | (_, true, true, _) => ReproducibilityLevel::Silver,
        _ => ReproducibilityLevel::Bronze,
    }
}
```

### 9.4 Golden Trace Validation (Renacer Integration)

For transpilers and distributed systems, integrate with `renacer` golden tracing:

```bash
# Query oracle for golden trace recipe
$ batuta oracle --recipe quality-golden-trace

# Integration with pmat comply
$ pmat comply --golden-trace renacer.toml
```

**Proposed Check (CB-302): Golden Trace Drift**

```rust
/// CB-302: Detect golden trace divergence
pub fn check_golden_trace_drift(project_path: &Path) -> Vec<CbViolation> {
    // Check if renacer.toml exists
    let config = project_path.join("renacer.toml");
    if !config.exists() {
        return vec![]; // Not a transpiler/distributed project
    }

    // Run renacer validate and capture output
    let output = Command::new("renacer")
        .args(["validate", "--all"])
        .current_dir(project_path)
        .output();

    match output {
        Ok(o) if o.status.success() => vec![],
        Ok(o) => vec![CbViolation {
            id: "CB-302".into(),
            message: format!("Golden trace divergence: {}", String::from_utf8_lossy(&o.stderr)),
            severity: Severity::Critical,
        }],
        Err(e) => vec![CbViolation {
            id: "CB-302".into(),
            message: format!("Failed to run renacer: {}", e),
            severity: Severity::Warning,
        }],
    }
}
```

### 9.5 Equation-Driven Development (EDD) Validation

For simulation projects, verify governing equations have proofs:

```bash
# Query oracle for EDD recipe
$ batuta oracle --recipe quality-edd
```

**Proposed Check (CB-303): EDD Compliance**

```rust
/// CB-303: Verify simulation code has equation documentation
pub fn check_edd_compliance(project_path: &Path) -> Vec<CbViolation> {
    // Only applies to simular-based projects
    let cargo_toml = project_path.join("Cargo.toml");
    if !file_contains(&cargo_toml, "simular") {
        return vec![]; // Not a simulation project
    }

    let mut violations = vec![];

    // Check for Equation Model Cards
    let has_emc = project_path.join("docs").join("equations").exists()
        || glob_exists(project_path, "**/*.emc.md");

    if !has_emc {
        violations.push(CbViolation {
            id: "CB-303-A".into(),
            message: "Simulation project missing Equation Model Cards (docs/equations/)".into(),
            severity: Severity::Warning,
        });
    }

    // Check for verify_invariants() implementation
    let has_invariant_check = grep_exists(project_path, "fn verify_invariants");
    if !has_invariant_check {
        violations.push(CbViolation {
            id: "CB-303-B".into(),
            message: "Simulation missing verify_invariants() method".into(),
            severity: Severity::Warning,
        });
    }

    violations
}
```

### 9.6 Enhanced Checklist Format

Following the Sovereign AI Assurance Protocol, each check should have:

| Field | Description |
|-------|-------------|
| **Claim** | What the code asserts (e.g., "No runtime panics from stubs") |
| **Falsification Test** | Command to attempt disproof |
| **Null Hypothesis (H₀)** | Assumed true until disproven |
| **Rejection Criteria** | Conditions that falsify the claim |
| **TPS Principle** | Toyota Way mapping |
| **Evidence Required** | Data for evaluation |

**Example: CB-050 in Enhanced Format**

| Field | Value |
|-------|-------|
| **Claim** | Code contains no runtime-panic stub macros |
| **Falsification Test** | `pmat comply --check cb-050` |
| **Null Hypothesis** | `todo!()` and `unimplemented!()` exist in production paths |
| **Rejection Criteria** | Any match of stub patterns outside test/doc contexts |
| **TPS Principle** | Jidoka — automatic stop on panic potential |
| **Evidence Required** | ☑ Pattern match locations ☑ Context analysis (test/doc/prod) |

### 9.7 Architectural Invariants

From the Sovereign AI Assurance Protocol, two non-negotiable requirements:

**1. Declarative Configuration (YAML-First)**

Every quality check should be configurable via YAML without code changes:

```yaml
# .pmat.yaml - Declarative quality gate configuration
comply:
  checks:
    cb-050: { enabled: true, severity: critical }
    cb-060: { enabled: true, severity: high }
    cb-128: { enabled: true, threshold: 5.0 }
  thresholds:
    coverage: 95.0
    complexity: 20
    dead_code_pct: 1.0
```

**2. Zero False Positive Policy**

Following Toyota's "Stop the Line" principle, any false positive must be:
1. Reported immediately (GitHub issue)
2. Fixed within 24 hours (patch release)
3. Added to the false positive regression suite
