Completes Task #3 of httpclient dogfooding with 100% detection rate (7/7 violations). ## New Extractors - **OptionBoundsExtractor**: Detects Option<T> fields set to None (unbounded) - **OptionValueExtractor**: Extracts values from Some(n) for threshold checks Both extractors use context-aware pattern matching to understand Rust Option<T> semantics, which declarative extractors cannot handle. ## Implementation **Files Created**: - applications/aphoria/src/extractors/option_bounds.rs (257 lines) - applications/aphoria/src/extractors/option_value.rs (277 lines) - applications/aphoria/docs/examples/extractors/programmatic-option-semantics.md **Files Modified**: - applications/aphoria/src/extractors/mod.rs - Added module declarations - applications/aphoria/src/extractors/registry.rs - Registered extractors - applications/aphoria/dogfood/httpclient/.aphoria/claims.toml - Added 4 claims - applications/aphoria/dogfood/httpclient/TASK-1-SUMMARY.md - Task #3 completion ## Results | Metric | Value | |--------|-------| | Detection Rate | 100% (7/7 violations) | | Improvement | +29 percentage points (from 71%) | | New Violations | 2 (max_redirects, max_retries unbounded) | | Unit Tests | 13 (all passing) | ## Two-Claim Strategy For each bounded Option<T> field: 1. **configured** claim - Detects None (unbounded) 2. **max_value** claim - Validates Some(n) threshold Example: - `max_redirects: None` → CONFLICT (not configured) - `max_redirects: Some(20)` → CONFLICT (exceeds 10) - `max_redirects: Some(5)` → PASS ## Enterprise Quality ✓ Proper error handling (no unwrap/expect) ✓ Comprehensive tests (6+7 unit tests) ✓ Full documentation with examples ✓ Reusable for 10+ similar patterns ✓ Screening patterns for performance ## Cachewrap Dogfood Also includes complete cachewrap dogfood exercise: - 10 claims for Redis cache wrapper - Day 1-5 summaries - Full retrospective and evaluation - Declarative extractors for all patterns Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
