Phase 4: Quality Gates Definition

Status: Phase 4 Implementation Standard Priority: P0 - Enforcement Date: December 30, 2025 Scope: All pull requests and code merges

Executive Summary

This document defines mandatory quality gates for code merges in HeliosDB. Quality gates are automated and manual checks that prevent code from being merged until standards are met. Phase 4 implements 4 tiers of gates (Automated, Documentation, Consolidation, IP/Patent) with clear pass/fail criteria.

Purpose: Shift from analysis-only governance to enforcement-driven quality management.

Tier 2: Documentation	Automated (CI/CD)	Every PR	Links valid + indices updated + naming correct
Tier 3: Consolidation	Manual (Engineering Lead)	Crate changes	Dependency analysis + testing + migration verified
Tier 4: IP/Patent	Manual (IP Lead)	New features	Protocol documented + patent filed/assessed

2. Tier 1: Code Quality Gate (AUTOMATED)

2.1 Gate Trigger

Activated on: Every pull request

Duration: Runs immediately on PR open and updates on each commit

2.2 Gate Checks

Check 2.2.1: Clippy Linting

Pass Criteria:

Zero clippy warnings (treated as errors)
No unwrap_used warnings (unless in test code)
No expect_used warnings (unless in test code)
No panic warnings (unless in test code)
No unimplemented warnings
No todo warnings

Failure Message:

❌ Code Quality Gate: FAILED
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Clippy Linting Violations (3 found):

[1] src/protocols/postgresql.rs:456:5
    warning: use of `unwrap_used` in user-facing code
    suggestion: Use Result<T, E> with ? operator
    severity: HIGH

[2] src/storage/lsm.rs:234:10
    warning: use of `expect_used` in Tier 1 code
    suggestion: Proper error handling required
    severity: HIGH

[3] src/api/rest.rs:112:3
    error: unchecked arithmetic operation
    suggestion: Use checked_add() instead of +
    severity: MEDIUM

Resolution:

  2. Review and approve auto-fixes: git diff
  3. Commit changes and push
  4. Rerun: Will automatically recheck on push

Pass Action: Green checkmark ✓ in PR status

Check 2.2.2: Error Handling Validation

Tool: Custom script scripts/verify/check_error_handling.sh

Pass Criteria:

No new unwrap/expect in user-facing code (Tier 1)
Tier 2 code: <5% of baseline unwrap/expect
All fallible operations use Result<T, E> return type
map_err() used for error transformation
No new .lock().unwrap() patterns

Failure Message:

❌ Code Quality Gate: FAILED
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Error Handling Violations (5 found):

[NEW] src/protocols/mongodb.rs:234:5
  - mongodb_query().unwrap() in user-facing handler
  - Category: Tier 1 violation (critical)
  - References: handle_query() → user query processing

[NEW] src/cache/lru.rs:112:10
  - SHARED_CACHE.lock().unwrap() in cache update
  - Category: Mutex poison cascade risk
  - Fix: lock().map_err(|_| CacheError::Poisoned)?

Baseline Comparison:
  Tier 2 unwrap/expect count: 23,456 → 23,467 (↑11 new calls)
  Target: <5% growth (max +1,173)
  Status: ✓ WITHIN BOUNDS (0.047% growth)

Resolution:
  1. Review error handling violations above
  2. Replace unwrap/expect with Result<T, E> pattern
  3. Test error paths: cargo test
  4. Commit with "fix(error): Replace unwrap with Result"
  5. Rerun check

Pass Action: Green checkmark ✓ in PR status

Check 2.2.3: Test Coverage Validation

Pass Criteria (for changed code):

Overall coverage: ≥75% (maintained)
Changed code coverage: ≥85%
Error path coverage: ≥80% (at minimum)
Critical paths: ≥95%

Failure Message:

❌ Code Quality Gate: FAILED
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Test Coverage Insufficient:

File: src/protocols/postgresql.rs
  Overall coverage: 68% → 71% (↑3%, but below ≥85% target)
  Lines missed:
    - Line 234-256: error handling path (parse error)
    - Line 301: timeout recovery path
  Test cases needed: 2 (error cases)

File: src/api/rest.rs
  Changed lines: 45
  Covered lines: 31
  Uncovered: 14 (31% gap)
  Suggest: Add tests for error responses and edge cases

Coverage Report: target/coverage/index.html

Resolution:
  1. Review uncovered code paths
  2. Add test cases for error scenarios
  3. Run: cargo tarpaulin (verify coverage increase)
  4. Target: Changed code ≥85%, error paths ≥80%
  5. Commit: "test: Add coverage for error paths"
  6. Rerun check

Pass Action: Green checkmark ✓ in PR status

Check 2.2.4: Unsafe Code Review

Tool: grep -r "unsafe {" src/ | wc -l and context analysis

Pass Criteria:

No new unsafe blocks without justification
Unsafe blocks documented with SAFETY comment
Each unsafe block justified in PR description
Unsafe code limited to performance-critical paths

Failure Message:

❌ Code Quality Gate: FAILED
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Unsafe Code Violations (1 found):

[NEW] src/storage/simd.rs:456-478
  unsafe {
      let ptr = buffer.as_mut_ptr();
      std::ptr::copy(other.as_ptr(), ptr, size);
  }

  Issue: No SAFETY comment explaining unsafe justification

  Requirement: All unsafe blocks must have SAFETY comment:

  // SAFETY: buffer is valid (allocated above at line 450)
  // copy_nonoverlapping is safe because we validated:
  // 1. src and dst don't overlap (different allocations)
  // 2. size is valid (checked at line 454)

Resolution:
  1. Add SAFETY comment explaining memory safety
  2. Justify why unsafe is necessary
  3. Document what invariants are maintained
  4. Add test case demonstrating correct behavior
  5. Rerun check

Pass Action: Green checkmark ✓ in PR status
