# Documentation Fixes Based on msgqueue Day 3 Evaluation

**Date:** 2026-02-10
**Based on:** `EVALUATION-REPORT-2026-02-10.md`

---

## Summary

Fixed **4 critical documentation gaps** identified during msgqueue Day 3 second attempt failure. All P0 and P1 findings addressed.

---

## What Was Fixed

### 1. Created Declarative Extractor Reference (P0 - Finding 1)

**File:** `applications/aphoria/docs/extractors/declarative-extractors.md`

**What it covers:**
- Complete field reference for declarative extractors
- **`subject` field format** (CRITICAL - most common mistake)
- Tail-path matching explained
- 3 complete worked examples (timeout, unbounded queue, TLS disabled)
- Common mistakes with fixes
- Validation workflow (grep subject vs concept_path)
- Debugging 0% detection rate
- FAQ section

**Key sections:**
- **`subject` field warning:** "⚠️ MOST COMMON MISTAKE: Using partial path instead of full path"
- **Rule of thumb:** "Copy `concept_path` from your claim EXACTLY into `subject` field"
- **Debug workflow:** Step-by-step process when detection rate is 0%

**Size:** ~800 lines (comprehensive reference)

---

### 2. Created Worked Example (P1 - Finding 3)

**File:** `applications/aphoria/docs/examples/extractors/timeout-zero-example.md`

**What it shows:**
- Complete flow: code → extractor → claim → conflict detection → fix
- Step-by-step breakdown with line numbers
- Exact TOML formatting
- How path alignment works
- Visual flow diagram
- Troubleshooting common problems
- Validation checklist

**Key sections:**
- **Path alignment:** Shows why `subject = "msgqueue/config/timeout"` must match claim exactly
- **Comparison logic:** How observations compare to claims
- **Debugging:** What to check when extractor doesn't work

**Size:** ~500 lines (complete end-to-end example)

---

### 3. Updated plan.md with Manual Fallback (P1 - Finding 4)

**File:** `dogfood/msgqueue/plan.md` (Day 3 Step 3)

**What was added:**
- Complete declarative extractor TOML format
- **Emphasis:** `subject` must EXACTLY match claim's `concept_path`
- Worked example (timeout=0)
- Validation steps BEFORE scanning (grep subject vs concept_path, test regex)
- Link to full reference doc

**Before (line 303):**
```markdown
If skill is unavailable: You can manually create declarative extractors, but this is NOT recommended.
```

**After (lines 303-341):**
```markdown
If skill is unavailable: You can manually create declarative extractors. Follow the format below:

[Complete TOML format with field explanations]
[Validation workflow]
[Example extractor]
[Link to docs/extractors/declarative-extractors.md]
```

**Impact:** Users can now create extractors manually with correct format.

---

### 4. Updated plan.md with Debug Workflow (P0 - Finding 2)

**File:** `dogfood/msgqueue/plan.md` (Day 3 Step 4)

**What was added:**
- Debug workflow for "0% detection after creating extractors"
- Step-by-step debugging commands (jq queries, grep comparisons)
- Explanation of tail-path mismatch
- Example fix showing before/after
- Re-scan instructions

**Before (lines 307-320):**
```markdown
### Step 4: Verification Scan

[Run scan]
[Compare v1 vs v2]
```

**After (lines 307-385):**
```markdown
### Step 4: Verification Scan

[Run scan]
[Compare v1 vs v2]

**If detection rate is still 0% (extractors don't match claims):**
[Complete debug workflow with 4 steps]
[Common issue explanation]
[Example fix]
[Re-scan instructions]
```

**Impact:** Users can debug why extractors don't work without external help.

---

### 5. Updated Common Mistakes Doc (New Finding)

**File:** `applications/aphoria/docs/dogfooding-common-mistakes.md`

**What was added:**
- New **Mistake #2:** Creating extractors with wrong subject format
- Evidence from msgqueue second attempt (7 extractors, 0% detection)
- Table showing all 7 extractors with wrong paths
- Validation workflow (how to check before scanning)
- Debug workflow (how to fix after scanning)
- Comparison table (First attempt vs Second attempt vs Correct)

**Renumbered existing mistakes:**
- Old Mistake #2 → New Mistake #3 (Treating Aphoria as Static Scanner)
- Old Mistake #3 → New Mistake #4 (Not Verifying Prerequisites)
- Old Mistake #4 → New Mistake #5 (Skipping Gap Analysis)
- Old Mistake #5 → New Mistake #6 (No Time Tracking)
- Old Mistake #6 → New Mistake #7 (No Detection Rate Calculation)
- Old Mistake #7 → New Mistake #8 (Not Comparing to httpclient)

**Size:** +250 lines (comprehensive new mistake documentation)

## Gap Coverage Analysis

| Finding | Priority | Status | Files Changed |
|---------|----------|--------|---------------|
| Finding 1: Subject field format undocumented | P0 | ✅ FIXED | `docs/extractors/declarative-extractors.md` (NEW) |
| Finding 2: No debug visibility | P0 | ✅ FIXED | `dogfood/msgqueue/plan.md` (Step 4 updated) |
| Finding 3: No worked example | P1 | ✅ FIXED | `docs/examples/extractors/timeout-zero-example.md` (NEW) |
| Finding 4: Manual fallback not shown | P1 | ✅ FIXED | `dogfood/msgqueue/plan.md` (Step 3 updated) |
| Finding 5: No validation command | P2 | 📋 DOC WORKAROUND | `docs/extractors/declarative-extractors.md` (grep workflow) |
| Finding 6: No single-extractor test | P2 | 📋 DOC WORKAROUND | `docs/extractors/declarative-extractors.md` (grep test) |

**P0-P1 gaps:** All fixed with documentation
**P2 gaps:** Documented workarounds until product features exist

---

## Product Gaps Remaining (Require Code Changes)

These require **product features**, not just docs:

| Gap ID | Title | Severity | Blocks Day 3? | Workaround Documented? |
|--------|-------|----------|---------------|------------------------|
| VG-DAY3-001 | No `--show-observations` flag | P0 | Yes | ✅ (manual jq inspection) |
| VG-DAY3-002 | Concept path alignment undocumented | P0 | Yes | ✅ FIXED (new doc) |
| VG-DAY3-003 | No extractor validation command | P2 | No | ✅ (grep + taplo) |
| VG-DAY3-004 | No single-extractor test | P2 | No | ✅ (grep pattern test) |

**Critical:** VG-DAY3-001 (`--show-observations`) is only remaining P0 blocker without documentation fix. Workaround exists but is manual.

---

   - Impact: Documents both failure modes (skip extractors vs wrong format)

---

## What Changed for Users

### Before These Fixes

**Day 3 Step 3 (Extractor Creation):**
- Showed skill invocation only
- Said "manual not recommended" with no format
- Users had to guess TOML structure
- No validation workflow

**Result:**
- 70 minutes spent creating extractors with wrong format
- 0% detection despite creating 7 extractors
- No way to debug why extractors don't work

### After These Fixes

**Day 3 Step 3 (Extractor Creation):**
- Shows skill invocation (primary)
- Shows complete manual TOML format (fallback)
- **Critical field highlighted:** `subject` must match `concept_path` EXACTLY
- Validation workflow (check alignment BEFORE scanning)
- Link to comprehensive reference doc

**Day 3 Step 4 (Verification):**
- Shows expected result (90%+ detection)
- **New:** Debug workflow if detection is still 0%
- Step-by-step commands (jq, grep comparisons)
- Common issue explanation (subject mismatch)
- Example fix with before/after

**Result:**
- Users can create working extractors manually
- Users can debug extractor alignment issues
- Users can validate BEFORE scanning (faster iteration)

---

## Validation

To validate these fixes, next msgqueue retry should:

1. **Follow plan.md Day 3 Step 3 manual fallback**
2. **Use validation workflow BEFORE scanning:**
   ```bash
   grep "subject =" .aphoria/config.toml
   grep "concept_path =" .aphoria/claims.toml
   # Verify alignment
   ```
3. **If 0% detection, follow Step 4 debug workflow:**
   ```bash
   jq '.observations | length' scan-results-v2.json
   jq '.observations[].concept_path' scan-results-v2.json | sort -u
   # Compare paths, fix subject fields
   ```

**Success criteria:**
- Detection rate ≥90% on v2 scan (after fixes)
- Time ≤30 minutes for extractor creation + validation
- Zero trial-and-error (validation catches issues upfront)

---

## Next Steps

### Immediate (Before Next Retry)
- [x] Documentation fixes complete
- [ ] Review with team
- [ ] Retry msgqueue Day 3 with new docs

### Short Term (This Week)
- [ ] Implement VG-DAY3-001: `aphoria scan --show-observations`
