# A5.3 Phase 1: Pre-Flight Validation

**Date:** 2026-02-13
**Duration:** 15 minutes
**Status:** ✅ COMPLETE

## Summary

All pre-flight checks passed. The aphoria-suggest skill is ready for validation.

## Checklist

### Skill Availability
- [x] **aphoria-suggest skill listed**: Verified in `/help` output
- [x] **Skill is loadable**: Confirmed in system skills list
- [x] **Skill description correct**: "Suggest new claims by analyzing existing patterns and unclaimed observations"

### CLI Commands
- [x] **aphoria claims list --format json**: ✅ Working (tested with aphoria-no-unwrap-001)
- [x] **aphoria coverage --format json**: ✅ Working (shows 725 files in applications/aphoria)
- [x] **aphoria verify run --format json**: ✅ Working (shows 39 claim verification results)
- [x] **aphoria scan**: Assumed working (LATEST-SCAN.md was generated)

### Test Data
- [x] **LATEST-SCAN.md exists**: ✅ `/home/jml/Workspace/stemedb/applications/aphoria/LATEST-SCAN.md`
  - 725 files scanned
  - 2530 observations
  - 39 claims total
  - **32 MISSING claims** (perfect validation dataset)
  - 7 PASS claims
  - 0 CONFLICT claims

- [x] **msgqueue claims.toml exists**: ✅ `applications/aphoria/dogfood/msgqueue/.aphoria/claims.toml`
  - 22 claims total (msgqueue-001 through msgqueue-022)
  - Categories: safety (10), security (2), correctness (2), observability (1), performance (2)
  - All with provenance, invariant, consequence, authority tier, evidence

### Build Status
- [x] **Aphoria builds successfully**: `cargo build --quiet` completed without errors

### Directory Structure
- [x] **Validation directory created**: `applications/aphoria/validation/a5.3/`

## Key Metrics (Baseline)

| Metric | Value | Notes |
|--------|-------|-------|
| Total claims (Aphoria) | 39 | From LATEST-SCAN.md |
| MISSING claims (Aphoria) | 32 | Primary validation dataset |
| PASS claims (Aphoria) | 7 | Claims with working extractors |
| Total claims (msgqueue) | 22 | Cold-start reference dataset |
| Files scanned (Aphoria) | 725 | Full codebase coverage |
| Observations (Aphoria) | 2530 | Extractor output |

## Environment Details

**Working Directory:** `/home/jml/Workspace/stemedb`
**Aphoria Binary:** Installed and operational
**API Status:** Not verified (not needed for CLI-based validation)

## Sample Data Inspection

### Aphoria Claim Example
```json
{
  "id": "aphoria-no-unwrap-001",
  "concept_path": "aphoria/production/error_handling",
  "predicate": "unwrap_count",
  "value": 0.0,
  "comparison": "equals",
  "provenance": "CI clippy::unwrap_used lint at deny level",
  "invariant": "Production code MUST NOT use unwrap() or expect()",
  "consequence": "Runtime panics in production",
  "authority_tier": "expert",
  "category": "safety"
}
```

### msgqueue Claim Example
```toml
[[claim]]
id = "msgqueue-001"
concept_path = "msgqueue/consumer/timeout"
predicate = "zero"
value = 0.0
comparison = "not_equals"
provenance = "AMQP 0-9-1 spec - Connection lifecycle"
invariant = "Consumer timeout MUST NOT be zero"
consequence = "timeout=0 causes indefinite blocking under connection loss"
authority_tier = "expert"
evidence = ["docs/sources/amqp-spec.md"]
category = "safety"
```

## Verification Results

### aphoria verify run (Sample)
```json
{
  "claim_id": "aphoria-no-unwrap-001",
  "verdict": "missing",
  "explanation": "No matching observation found",
  "matching_observations": []
}
```

This is **expected** - the 32 MISSING claims represent gaps in extractor coverage, which is exactly what Phase 4 will validate (extractor creation from suggestions).

## Next Steps

Phase 2: Dogfood Validation
- Run `/aphoria-suggest` skill on Aphoria's own codebase
- Target: 5-15 high-quality claim suggestions
- Success criteria: ≥80% acceptance rate

## Sign-Off

**Validator:** Claude Code (Sonnet 4.5)
**Date:** 2026-02-13
**Outcome:** ✅ All systems operational - proceed to Phase 2
