Canary CLI — Next Slices¶

Completed¶

✅ Evidence-Based Gap Analysis (2025-10-15 Initial)¶

Scope: Built canary binary, ran acceptance tests, scanned tools/canary for tokens, verified self-canary dogfood.
Artifacts: GAP_ANALYSIS.md, CHECKLIST.md, tools-canary-status.json
Status: TESTED (acceptance validation complete)

✅ Phase 1: TestCANARY_* Functions (2025-10-15)¶

Scope: Implemented 3 unit tests matching token references exactly
Deliverables:
tools/canary/main_test.go — TestCANARY_CBIN_101_Engine_ScanBasic
tools/canary/verify_test.go — TestCANARY_CBIN_102_CLI_Verify
tools/canary/status_test.go — TestCANARY_CBIN_103_API_StatusSchema
Validation: go test -run TestCANARY_CBIN -v → 3/3 PASS
Status: COMPLETED (all tests pass, names match token refs)

✅ Phase 2: BenchmarkCANARY_* Functions (2025-10-15)¶

Scope: Implemented 4 performance benchmarks with baseline measurements
Deliverables:
BenchmarkCANARY_CBIN_101_Engine_Scan → 3.3ms/100 files, 1.1MB, 11353 allocs
BenchmarkCANARY_CBIN_101_Engine_Scan50k → 1.85s/50k files, 557MB, 5.5M allocs (Slice 10)
BenchmarkCANARY_CBIN_102_CLI_Verify → 36µs/50 claims, 5.2KB, 13 allocs
BenchmarkCANARY_CBIN_103_API_Emit → 0.9ms/300 tokens, 36KB, 2119 allocs
Token Updates: All 3 tokens → STATUS=BENCHED, UPDATED=2025-10-15
Validation: go test -bench BenchmarkCANARY -run ^$ -benchmem → 4/4 RUN
Status: COMPLETED (baselines established, 50k perf: 1.85s with 81.5% headroom)

✅ Phase 3: Documentation Updates (2025-10-15)¶

Scope: Updated GAP_ANALYSIS.md, CHECKLIST.md, NEXT.md with Phase 1 & 2 results
Changes:
Marked gaps #1 and #2 as RESOLVED in all docs
Added benchmark baselines to GAP_ANALYSIS.md
Updated evidence collection commands
Moved Slices 1-6 from "Up Next" to "Completed"
Status: COMPLETED

✅ Slice 7: Fix CRUSH.md Placeholder (2025-10-15)¶

Scope: Removed invalid CANARY token causing parse errors
Files Modified: CRUSH.md:27, README.md:29, docs/CANARY_EXAMPLES_SPEC_KIT.md:8
Issue: Lines contained ASPECT=<ASPECT> placeholder causing CANARY_PARSE_ERROR
Fix: Replaced with valid concrete examples using actual enum values (ASPECT=API, STATUS=IMPL)
Validation: ./bin/canary --root tools/canary --out status.json → EXIT=0 (no parse errors)
Evidence: SLICE_7_COMPLETE.md
Status: COMPLETED (5 min)

✅ Slice 8: Add CI Workflow (2025-10-15)¶

Scope: Created GitHub Actions workflow for canary validation
File: .github/workflows/canary.yml (5 jobs)
Jobs:
build — go build -o ./bin/canary ./tools/canary
test-unit — go test ./tools/canary -v -run TestCANARY
test-acceptance — go test ./tools/canary/internal -v -run TestAcceptance
benchmark — go test ./tools/canary -bench BenchmarkCANARY -run ^$ -benchmem
verify-self — ./bin/canary --root tools/canary --verify GAP_SELF.md --strict --skip '...'
Triggers: push to main, pull_request to main
Validation: All 5 jobs validated locally (PASS)
Evidence: SLICE_8_COMPLETE.md
Status: COMPLETED (20 min)

✅ Slice 9: CSV Row Order Test (2025-10-15)¶

Scope: Validated deterministic CSV row ordering
File: tools/canary/internal/acceptance_test.go:136
Test: TestAcceptance_CSVOrder
Logic:
Created fixture with 5 requirements in non-alphabetical order (CBIN-999, CBIN-101, CBIN-500, etc.)
Scanned twice and compared CSV outputs byte-for-byte
Verified rows sorted by REQ ID ascending
Validation: go test ./tools/canary/internal -run TestAcceptance_CSVOrder -v → PASS
Evidence: SLICE_9_COMPLETE.md
Status: COMPLETED (15 min)

✅ Slice 10: Large-Scale Performance Benchmark (2025-10-15)¶

Scope: Definitive validation of <10s requirement for 50k files
File: tools/canary/main_test.go:102
Benchmark: BenchmarkCANARY_CBIN_101_Engine_Scan50k
Setup: Generated 50,000 files with CANARY tokens in temp dir
Results:
Scan time: 1.85s (81.5% headroom under <10s target)
Memory: 557MB
Throughput: ~27,300 files/second
Validation: go test ./tools/canary -bench BenchmarkCANARY_CBIN_101_Engine_Scan50k -run ^$ -benchmem -benchtime=1x → PASS
Evidence: SLICE_10_COMPLETE.md
Status: COMPLETED (10 min)

✅ Slice 11: JSON Determinism Test (2025-10-15)¶

Scope: Validated JSON output is byte-for-byte identical across multiple runs
File: tools/canary/status_test.go:127
Test: TestCANARY_CBIN_103_API_JSONDeterminism
Logic:
Created fixture with 20 CANARY tokens
Ran scanner 5 times
Computed SHA256 hash of each JSON output
Verified all hashes identical
Validation: go test ./tools/canary -run TestCANARY_CBIN_103_API_JSONDeterminism -v → PASS
Evidence: SLICE_11_COMPLETE.md
Gap Resolution: Gap #9 (JSON determinism) RESOLVED
Status: COMPLETED (15 min)

✅ Slice 13: Regex Portability Tests (2025-10-16)¶

Scope: Validated --skip regex handles edge cases correctly
File: tools/canary/internal/acceptance_test.go:211
Test: TestAcceptance_SkipEdgeCases
Fixtures Created:
Unicode filename (测试.go - Chinese characters)
Filename with spaces (file with spaces.go)
Hidden files (.hidden, .git/config)
Excluded directories (node_modules, vendor)
Logic:
Created fixture with edge case files
Ran scanner with skip pattern
Verified expected files scanned (CBIN-001, 002, 003, 004)
Verified excluded files skipped (CBIN-096, 097, 098, 099)
Validation: go test ./tools/canary/internal -run TestAcceptance_SkipEdgeCases -v → PASS
Evidence: SLICE_13_COMPLETE.md
Gap Resolution: Gap #6 (regex portability) RESOLVED
Status: COMPLETED (20 min)

✅ Slice 14: Stale Token Auto-Update (2025-10-16)¶

Scope: Added --update-stale flag to automatically rewrite UPDATED field
File: tools/canary/main.go:75 (flag), main.go:290-389 (updateStaleTokens function)
CLI Flag: --update-stale
Logic:
Scans for TESTED/BENCHED tokens with UPDATED > 30 days
Parses stale diagnostics to extract REQ IDs
Walks directory tree, respects skip patterns
Rewrites UPDATED field to current date (preserves formatting)
Re-scans after updates for fresh status
Test: TestAcceptance_UpdateStale (acceptance_test.go:336)
Validation:
CBIN-001 (TESTED, stale) → updated to 2025-10-16 ✅
CBIN-002 (TESTED, fresh) → unchanged ✅
CBIN-003 (IMPL, stale) → unchanged (only TESTED/BENCHED updated) ✅
CBIN-004 (BENCHED, stale) → updated to 2025-10-16 ✅
Issues Resolved:
Assignment mismatch in parseKV call
Test validation logic error
TestAcceptance_SelfCanary finding test fixtures (added internal/ to skip)
Evidence: SLICE_14_COMPLETE.md
Gap Resolution: Gap #10 (stale token UX) RESOLVED
Status: COMPLETED (2 hours)
