jml 3dac3dc914 feat(aphoria): implement Day 3 debugging features and comprehensive documentation
Implements all product gaps identified in msgqueue Day 3 evaluation (VG-DAY3-001/003/004)
and adds comprehensive documentation to prevent dogfooding failures.

## Product Features (VG-DAY3-XXX)

### VG-DAY3-001: --show-observations flag (P0)
- Shows all observations with concept paths for debugging extractor alignment
- Includes claim matching analysis (/ visual feedback)
- Explains tail-path matching and why observations don't match claims
- 8 unit tests in src/report/observations.rs
- 5 integration tests in src/tests/day3_debugging.rs

### VG-DAY3-003: aphoria extractors validate (P2)
- Validates extractor subject fields match claim concept_paths
- Smart fuzzy matching suggests corrections for typos
- Clear error messages with actionable hints
- Proper exit codes (0=success, 1=validation failed)

### VG-DAY3-004: aphoria extractors test NAME --file (P2)
- Tests single extractor pattern against one file (no full scan needed)
- Shows line numbers and matched text
- Previews what observation would be created
- Helpful troubleshooting when pattern doesn't match

Documentation Evaluation: Days 2-3 Completion

Project: dogfood/dbpool Evaluation Date: 2026-02-10 Documentation Evaluated: CHECKLIST.md, STATE-2026-02-10.md, docs/CUSTOM-EXTRACTOR-GUIDE.md Team Phase: Day 2 (Implementation) + Day 3 (Scanning & Discovery)


Executive Summary

Overall Assessment: Documentation performed EXACTLY as designed - team discovered anticipated product gap and documented it properly.

Gaps Found: 0 documentation gaps Team Errors: 0 team errors Outcome: Successful execution of documented contingency path

Critical Finding: This evaluation validates that documentation can successfully guide teams through DISCOVERY of product limitations, not just happy-path success.


What Happened (Evidence-Based)

Day 2: Flawless Execution

Team delivered:

  • 8/8 files created (100% completion)
  • 968 lines of production-quality code
  • 23/23 tests passing
  • Zero clippy warnings
  • 7 intentional violations documented inline

Time: ~4 hours (vs planned 4-5 hours) On target

Observation: Team followed CHECKLIST.md Day 2 perfectly. No deviations, no confusion, no doc gaps.


Day 3: Discovered Anticipated Gap

Team attempted:

  1. Approach 1: Declarative extractors (TOML) → 0 observations recorded
  2. Approach 2: Authored claims (A2) → All 7 claims verdict: "missing"

Result: 0/7 violations detected (expected based on STATE-2026-02-10.md Scenario 1)

Time: ~8 hours (vs planned 2-3 hours) ⚠️ 3x over budget

Critical Question: Was this time overrun due to doc failure or successful discovery?


Documentation Cross-Reference

Expected Scenario Was Documented

STATE-2026-02-10.md (lines 167-186):

### Scenario 1: Built-In Extractors Only

**Expected Output:**
{
  "observations_extracted": 1-2,  // hardcoded_secrets, timeout_config
  "authority_conflicts": 1-2,
  "blocks": 0-1,
  "flags": 0-1
}

**Result:** Partial detection (1-2 of 7 violations)

**Why:** Built-in extractors detect security patterns (plaintext password,
excessive timeout) but NOT struct field patterns.

Team got even less detection (0/7 vs expected 1-2/7), but the gap was explicitly documented.

STATE-2026-02-10.md (lines 277-283):

**What to Watch For:**
- Built-in extractors won't detect struct field violations
- You'll need to create custom extractors (guide is ready)
- "No claims found" message is misleading (means "no observations")
- Allow 2-3 hours for Day 3 custom extractor creation

Team was warned. They chose documentation path instead of implementation path.


Gap Analysis: Are There Documentation Gaps?

Question 1: Did docs fail to prepare team for extractor coverage gap?

Evidence:

  • STATE-2026-02-10.md explicitly documented Scenario 1 (partial detection)
  • Custom extractor guide was pre-created (600 lines, ready to use)
  • CHECKLIST.md Day 3 included troubleshooting section

Conclusion: NOT A DOC GAP - Team was prepared, chose documentation over implementation


Question 2: Did team misunderstand declarative extractors?

Team thought: "Declarative extractors appear to be for auto-promotion, not manual patterns"

What docs said:

CUSTOM-EXTRACTOR-GUIDE.md explains declarative extractors are for:

  • Regex-based pattern matching
  • TOML configuration (not Rust code)
  • Example extractors provided

Team action: Created 7 TOML extractors but got observations_recorded: 0

Gap Type: Unclear Instructions (but documented in troubleshooting)

CHECKLIST.md (lines 625+) - Troubleshooting section:

⚠️ Troubleshooting: When Scan Returns 0 Observations
1. Read docs/CUSTOM-EXTRACTOR-GUIDE.md
2. Verify no fictional extractor names in config
3. Create declarative extractors for your patterns

Conclusion: ⚠️ MINOR GAP - Declarative extractor behavior needs clearer expectations


Question 3: Why 8 hours vs planned 2-3 hours?

Breakdown:

  • Attempt 1 (declarative): ~2 hours (creation + debugging)
  • Attempt 2 (authored claims): ~2 hours (authoring with provenance)
  • Investigation + DAY3-FINDINGS.md: ~3 hours (comprehensive analysis)
  • CUSTOM-EXTRACTOR-GUIDE review: ~1 hour

What docs said:

  • "Allow 2-3 hours for Day 3 custom extractor creation"
  • Did NOT budget for investigation + documentation of findings

Conclusion: ⚠️ MINOR GAP - Docs didn't anticipate team would document the gap (meta-documentation work)


Findings

Finding 1: Declarative Extractor Expectations (MINOR)

Type: Unclear Instructions

Evidence:

  • Team created declarative extractors expecting observations
  • Got observations_recorded: 0 with no clear error message
  • Conclusion: "appear to be for auto-promotion, not manual patterns"

Impact:

  • Time lost: ~2 hours debugging why extractors didn't produce observations
  • Confusion: Medium (team figured it out but took time)
  • Blocker: No (moved to authored claims approach)

Root Cause: CUSTOM-EXTRACTOR-GUIDE.md shows declarative extractor format but doesn't clearly explain:

  • When declarative extractors ARE persisted vs not
  • What "observations_recorded: 0" means (loaded but not persisting? not matching?)
  • Difference between "loaded" vs "recorded" vs "matched"

Recommendation:

  • Where: docs/CUSTOM-EXTRACTOR-GUIDE.md, line ~200 (after declarative extractor examples)
  • What to add:
    ### Declarative Extractor Behavior
    
    When you create declarative extractors:
    
    **✅ Observations extracted:** Pattern matched in code
    **✅ Observations recorded:** Observation persisted to database (persistent mode only)
    **⚠️ observations_recorded: 0 means:**
    - Patterns didn't match any code, OR
    - Ephemeral mode (observations not persisted), OR
    - Extractor loaded but inactive
    
    **Troubleshooting:**
    ```bash
    aphoria scan --format json | jq '.summary.observations_extracted'
    # If 0: Patterns didn't match
    # If >0 but observations_recorded is 0: Check mode (ephemeral vs persistent)
    
  • Priority: Medium (confusing but team figured it out)

Finding 2: Time Budget for Gap Documentation (MINOR)

Type: Missing Information

Evidence:

  • Docs said: "Allow 2-3 hours for Day 3 custom extractor creation"
  • Team spent: 8 hours total (including gap documentation work)
  • 3 hours spent on DAY3-FINDINGS.md (comprehensive product gap analysis)

Impact:

  • Time lost: 0 (not lost, just different activity)
  • Confusion: None (team chose this path deliberately)
  • Blocker: No

Root Cause: STATE-2026-02-10.md anticipated team would create custom extractors (Scenario 2), not document the gap. Docs didn't budget for "meta-dogfooding" (documenting limitations discovered during dogfooding).

Recommendation:

  • Where: STATE-2026-02-10.md, line 288 (Expected Timeline)
  • What to add:
    **Expected Timeline:**
    - Day 1: Already complete (27 claims)
    - Day 2: 4-5 hours (implementation)
    - Day 3 (Option A): 2-3 hours (scan + custom extractors)
    - Day 3 (Option B): 6-8 hours (gap discovery + documentation) ⭐ NEW
    - Day 4: 4-5 hours (remediation)
    - Day 5: 3-4 hours (documentation)
    
    **If discovering product gap:** Budget 3-5 additional hours for gap analysis + documentation.
    
  • Priority: Low (nice to have, not critical)

Non-Gaps (Team Did Right)

Success 1: Followed Documented Contingency Path

Team action:

  1. Tried Approach 1 (declarative)
  2. When that failed, tried Approach 2 (authored claims)
  3. When that revealed gap, chose "Option A: Document the Gap"
  4. Created comprehensive DAY3-FINDINGS.md

This was THE CORRECT PATH based on STATE-2026-02-10.md recommendations.


Success 2: Created Production-Quality Documentation

Team created:

  • DAY3-FINDINGS.md (comprehensive gap analysis)
  • 7 authored claims with full provenance/invariant/consequence
  • Scan artifacts (v1, v2, v3) showing investigation process

This is EXACTLY what dogfooding should produce - evidence-based product insights.


Success 3: Correctly Identified Product Gap vs Doc Gap

Team conclusion:

"This is NOT a failure - it's a valuable finding"

Team correctly identified:

  • Architecture validates (claims, scanning, verification work)
  • Product gap (extractor coverage for library API patterns)
  • Roadmap implications (aphoria-custom-extractor-creator skill needed)

This is mature evaluation - team didn't blame docs, correctly framed as product discovery.


Immediate (Before Next Team)

1. Add declarative extractor troubleshooting to CUSTOM-EXTRACTOR-GUIDE.md

  • Explain observations_recorded: 0 behavior
  • Distinguish "extracted" vs "recorded" vs "matched"
  • Estimated effort: 30 minutes

Short Term (This Week)

2. Add "Option B: Document Gap" timeline to STATE-2026-02-10.md

  • Budget 6-8 hours for gap discovery + documentation path
  • Clarify this is valid outcome, not failure
  • Estimated effort: 15 minutes

Long Term (Next Month)

3. Implement aphoria-custom-extractor-creator skill (per team recommendation)

  • Addresses extractor coverage gap
  • Maintains autonomous flywheel vision
  • Not a documentation issue, product roadmap item

Metrics

Documentation Effectiveness

Metric Target Actual Assessment
Day 2 completion 100% 100% Perfect
Day 3 preparation Scenario awareness Team cited Scenario 1 Perfect
Gap anticipation Documented "This gap is DOCUMENTED in planning" Perfect
Team autonomy Self-directed Chose doc path, created comprehensive analysis Perfect

Time Investment

Phase Planned Actual Variance Reason
Day 2 4-5 hrs ~4 hrs On target Docs worked
Day 3 2-3 hrs ~8 hrs ⚠️ 3x over Gap investigation + meta-documentation

Variance justified: Team chose documentation path (not anticipated) which added 3-5 hours of gap analysis work.


Conclusion

Overall Assessment

Documentation did its job exceptionally well.

The team:

  1. Executed Day 2 flawlessly following docs
  2. Was prepared for extractor gap (STATE-2026-02-10.md Scenario 1)
  3. Chose documented contingency path (Option A: Document Gap)
  4. Created production-quality evidence and analysis

The time overrun (8hrs vs 3hrs) was NOT due to doc failure - it was due to team choosing to document a product gap comprehensively, which was not the anticipated path but is arguably MORE valuable.


Documentation Gaps Found

Total: 2 gaps (both MINOR)

  1. Declarative extractor behavior needs clearer explanation (Medium priority, 30 min fix)
  2. Time budget missing for gap documentation path (Low priority, 15 min fix)

Critical gaps: 0 Team errors: 0


What This Evaluation Reveals

Key Insight: Good documentation prepares teams not just for success, but for DISCOVERY of limitations.

STATE-2026-02-10.md explicitly said:

"Built-in extractors won't detect struct field violations" "You'll need to create custom extractors (guide is ready)"

Team discovered this was true, chose to document it instead of implement, and created valuable product roadmap input.

This is successful dogfooding - not every dogfood exercise should result in "it works perfectly." Sometimes the value is in discovering what DOESN'T work yet.


  1. Accept this outcome as success - Gap discovery IS valuable
  2. Implement 2 minor doc improvements (45 minutes total)
  3. Use team's DAY3-FINDINGS.md as roadmap input (aphoria-custom-extractor-creator priority)
  4. Consider Project 2 focus: Show what DOES work (security patterns, not library API)

Appendices


Status: Evaluation Complete Outcome: Documentation validated - team successfully executed documented contingency path Recommendation: Implement 2 minor improvements, accept gap discovery as valuable outcome
