# Documentation Evaluation Report - Run 2

**Project:** dogfood/dbpool
**Evaluation Date:** 2026-02-09
**Documentation Evaluated:**
- `CHECKLIST.md` (Days 1-2)
- `plan.md`
- `README.md`
- `docs/claim-extraction-example.md`

**Team Phase:** Completed Day 2 (Implementation)

---

## Executive Summary

**Overall Assessment:** Team produced excellent Day 2 implementation but **completely skipped Day 1**, creating a critical blocker for Day 3.

**Critical Finding:** Documentation presents Days 1-5 as parallel reference sections rather than sequential prerequisites. Team executed Day 2 perfectly (7/7 files, 21/21 tests passing, all violations embedded) but created 0/27 corpus claims from Day 1.

**Impact:** Day 3 scanning cannot proceed (scan requires claims). Estimated 8-10 hours lost (4-5 hours on Day 2, must backfill 4-6 hours for Day 1).

**Gaps Found:** 5 documentation gaps (2 critical)
- Missing Information: 2 gaps
- Unclear Instructions: 2 gaps
- Buried Information: 1 gap

**Team Errors (Not Gaps):** 0

**Critical Blockers:** 1 (Day 1 skipped - prevents Day 3 scan)

---

## Critical Findings (High Priority)

### Finding 1: No Prerequisite Relationship Between Days

**Type:** Missing Information
**Impact:** BLOCKER - Team skipped Day 1, cannot proceed to Day 3

**What Happened:**
- Team read CHECKLIST.md Day 1 section
- Team understood Day 1 requirements (progress log shows "Ready to Build Claims")
- Team proceeded directly to Day 2 implementation
- Team created 0/27 corpus claims
- Day 3 scan will return 0 violations (nothing to compare against)

**Evidence:**

Team execution:
```bash
# Day 1 requirement
$ curl 'http://localhost:18180/v1/aphoria/corpus?sources[]=vendor' | \
    jq '.items | map(select(.subject | startswith("dbpool"))) | length'
0

# Day 2 execution
$ ls src/
config.rs  connection.rs  error.rs  lib.rs  pool.rs

$ cargo test
test result: ok. 21 passed; 0 failed
```

Documentation does NOT say "Complete Day 1 before Day 2":

```markdown
CHECKLIST.md:103:
## Day 1: Create 25-30 Corpus Claims

[...280 lines of Day 1 content...]

CHECKLIST.md:276:
## Day 2: Implementation - Information Needed
```

**Root Cause:**

Documentation structure implies days are sections of a reference document, not sequential workflow steps.

**Location:** CHECKLIST.md between lines 280-276

**Fix Required:**

Add explicit checkpoint between Day 1 and Day 2:

```markdown
---

✅ **Day 1 Complete** when verification shows 25-30 claims in corpus

**⛔ CHECKPOINT: DO NOT PROCEED TO DAY 2 WITHOUT COMPLETING DAY 1**

Day 2 implementation requires corpus claims to exist for Day 3 scanning.
Without claims, scan will return 0 violations and the dogfood demo cannot proceed.

**Verify before continuing:**
\`\`\`bash
curl 'http://localhost:18180/v1/aphoria/corpus?sources[]=vendor' | \\
  jq '.items | map(select(.subject | startswith("dbpool"))) | length'
# Must show: 25-30 (current: 0)
\`\`\`

If verification fails, complete Day 1 checkboxes (27 claims) before proceeding.

---

## Day 2: Implementation - Information Needed
```

**Priority:** CRITICAL - Must fix before next team

---

### Finding 2: No Automated Verification Between Days

**Type:** Missing Information
**Impact:** BLOCKER ENABLER - Nothing prevents sequence violation

**What Happened:**
- Success criteria exist in Day 1 (CHECKLIST.md:105-110)
- Team did not run verification command
- Day 2 section does not require Day 1 verification
- No automated check prevents Day 2 without Day 1

**Evidence:**

Documentation shows success criteria but doesn't require running it:

```markdown
CHECKLIST.md:105:
**Success Criteria:**
\`\`\`bash
curl 'http://localhost:18180/v1/aphoria/corpus?sources[]=vendor' | \\
  jq '.items | map(select(.subject | startswith("dbpool"))) | length'
# Expected output: 25-30
\`\`\`
```

Team behavior:
- Did not run this command before Day 2
- Proceeded to Day 2 without verification
- No automated check caught the violation

**Root Cause:**

Success criteria presented as "expected output" documentation, not as "you must run this" checkpoint.

**Location:** Need new script + CHECKLIST.md Day 2 prerequisite

**Fix Required:**

**1. Create automated verifier:**

File: `scripts/verify-day1.sh`
```bash
#!/bin/bash
# Verify Day 1 completion before proceeding to Day 2

set -e

echo "=== Day 1 Verification ==="
echo

CLAIMS_COUNT=$(curl -s 'http://localhost:18180/v1/aphoria/corpus?sources[]=vendor' 2>/dev/null | \\
  jq '.items | map(select(.subject | startswith("dbpool"))) | length')

if [ "$CLAIMS_COUNT" -ge 25 ] && [ "$CLAIMS_COUNT" -le 30 ]; then
    echo "✓ Day 1 complete: $CLAIMS_COUNT claims in corpus"
    exit 0
else
    echo "✗ Day 1 incomplete: $CLAIMS_COUNT claims (expected 25-30)"
    echo
    echo "Complete Day 1 before proceeding:"
    echo "  1. Read: cat docs/claim-extraction-example.md"
    echo "  2. Create: Follow CHECKLIST.md Day 1, Step 3 (27 checkbox items)"
    echo "  3. Verify: Run this script again"
    exit 1
fi
```

**2. Add to Day 2 start:**

CHECKLIST.md:276:
```markdown
## Day 2: Implement Code with Intentional Violations

**Prerequisites:** Day 1 complete (25-30 claims in corpus)

- [ ] **Verify Day 1 completion**
  \`\`\`bash
  ./scripts/verify-day1.sh
  \`\`\`
  **⛔ Must pass before proceeding**

  Expected output:
  \`\`\`
  === Day 1 Verification ===

  ✓ Day 1 complete: 27 claims in corpus
  \`\`\`

  If verification fails, return to Day 1 and complete all 27 claim checkboxes.
```

**Priority:** CRITICAL - Prevents future sequence violations

---

## Medium Priority Improvements

### Finding 3: Day 2 Heading Implies Reference, Not Action

**Type:** Unclear Instructions
**Impact:** Contributes to day sequence confusion

**What Happened:**

Day 1 heading: "Create 25-30 Corpus Claims" (action verb)
Day 2 heading: "Implementation - Information Needed" (passive tone)

Team may have interpreted Day 2 as reference material rather than sequential action.

**Location:** CHECKLIST.md:276

**Fix:**

Change heading and add structured metadata:

```markdown
-## Day 2: Implementation - Information Needed
+## Day 2: Implement Code with Intentional Violations
+
+**Prerequisites:** Day 1 complete (25-30 claims in corpus)
+
+**Deliverable:** Working Rust library with 7 intentional violations
+
+**Success Criteria:**
+\`\`\`bash
+cargo test
+# Expected: 21/21 tests pass (violations are semantic, not syntax)
+\`\`\`
+
+**Estimated Time:** 4-5 hours
+
+---
```

**Priority:** MEDIUM (Improves clarity, prevents confusion)

---

### Finding 4: README Day-by-Day Table Shows All Days Equally

**Type:** Unclear Instructions
**Impact:** First impression suggests parallel sections

**What Happened:**

README.md shows all days in table with equal visual weight. No indication of prerequisites or sequence.

**Location:** README.md:70-78

**Fix:**

Add prerequisites column:

```markdown
| Day | Focus | Key Deliverable | Prerequisites | Time |
|-----|-------|-----------------|---------------|------|
| **Day 1** | Corpus Building | 25-30 claims created via CLI | *(start here)* | 4-6 hours |
| **Day 2** | Implementation | Working code with 7-8 intentional violations | Day 1 ✓ | 4-5 hours |
| **Day 3** | Scanning | Initial scan showing all violations | Day 2 ✓ | 2-3 hours |
| **Day 4** | Remediation | Progressive fixes with re-scans | Day 3 ✓ | 4-5 hours |
| **Day 5** | Documentation | Success story, demo materials | Day 4 ✓ | 3-4 hours |

**⚠️ IMPORTANT:** Days must be completed sequentially. Each day requires the previous day's deliverable.

**Verification checkpoints:**
- After Day 1: Run `./scripts/verify-day1.sh` (must show 25-30 claims)
- After Day 2: Run `cargo test` (must show 21/21 passing)
- After Day 3: Check scan results (must show 7-8 violations)
```

**Priority:** MEDIUM (First thing team sees, sets expectations)

---

## Low Priority Polish

### Finding 5: plan.md Status Table Lacks Prerequisite Column

**Type:** Buried Information
**Impact:** Visual parity - all days shown with equal status

**Location:** plan.md:88-96

**Fix:**

Add prerequisites column to status table:

```markdown
| Phase | Status | Prerequisites | Completed | Notes |
|-------|--------|---------------|-----------|-------|
| Day 1: Preparation | 🔄 IN PROGRESS | None | 2026-02-09 | Corpus building |
| Day 2: Implementation | ⏳ PENDING | Day 1 ✓ | - | Requires claims in corpus |
| Day 3: First Scan | ⏳ PENDING | Day 2 ✓ | - | Requires code with violations |
| Day 4: Remediation | ⏳ PENDING | Day 3 ✓ | - | Requires scan results |
| Day 5: Documentation | ⏳ PENDING | Day 4 ✓ | - | Requires fixed code |
```

**Priority:** LOW (Status table is for tracking, not primary instructions)

---

## Team Errors (For Reference)

**NONE IDENTIFIED**

Team behavior was systematic and logical given the documentation:
- Read documentation thoroughly (progress log shows understanding)
- Executed Day 2 perfectly (100% adherence to specifications)
- Did not skip steps within Day 2 (all 7 files, all violations)
- Comprehensive testing (21/21 tests passing)

**This is NOT a team error - this is a documentation failure.**

Documentation failed to communicate that Day 1 is a blocking prerequisite for Day 2.

---

## What Team Did Right

### Excellent Day 2 Implementation

**Files Created:** 7/7 (100%)
- Cargo.toml (matches dependencies exactly)
- src/lib.rs (clean module structure)
- src/config.rs (5 violations perfectly embedded)
- src/pool.rs (2 violations perfectly embedded)
- src/connection.rs (clean placeholder)
- src/error.rs (proper thiserror usage)
- tests/basic.rs (3 integration tests)

**Violations Embedded:** 7/7 (100%)
1. ✅ Unbounded max_connections (config.rs:25)
2. ✅ Plaintext password (config.rs:73)
3. ✅ Missing max_lifetime (config.rs:72)
4. ✅ Excessive connection_timeout (config.rs:71)
5. ✅ Zero min_connections (config.rs:70)
6. ✅ No connection validation (pool.rs:78)
7. ✅ No metrics exposed (pool.rs:24)

**Tests Passing:** 21/21 (100%)
- Unit tests: 13/13
- Integration tests: 3/3
- Doc tests: 5/5

**Code Quality:** Excellent
- Clean architecture
- Proper async/await usage
- Good error handling
- Comprehensive inline documentation
- Every violation documented with claim reference and consequence

**Example of excellent violation documentation:**

```rust
/// **VIOLATION 1**: Set to `None` (unbounded growth)
/// - Violates: `dbpool/max_connections` required claim
/// - Consequence: Pool grows without limit, exhausts database connections
pub max_connections: Option<usize>,
```

## Recovery Path for Current Team

**Team is currently blocked.** They cannot proceed to Day 3 without Day 1 completion.

### Step 1: Inform Team

```
⛔ CHECKPOINT FAILURE DETECTED

Your Day 2 implementation is excellent (7/7 files, 21/21 tests passing, all violations embedded).

However, Day 1 was not completed:
- Expected: 25-30 claims in corpus
- Actual: 0 claims

Day 3 scanning requires claims to exist. Without claims, scan will return 0 violations.

You must backfill Day 1 before proceeding.
```

### Step 2: Verify Current State

```bash
# Confirm Day 1 incomplete
./scripts/verify-day1.sh
# Expected: ✗ Day 1 incomplete: 0 claims (expected 25-30)

# Confirm Day 2 complete
cargo test
# Expected: test result: ok. 21 passed
```

### Step 3: Complete Day 1

```bash
# Follow CHECKLIST.md Day 1
# Create all 27 claims using aphoria corpus create CLI
# Estimated time: 4-6 hours
```

### Step 4: Verify Day 1 Completion

```bash
./scripts/verify-day1.sh
# Expected: ✓ Day 1 complete: 27 claims in corpus
```

### Step 5: Proceed to Day 3

```bash
# Now scanning will work
aphoria scan --format json > scan-results-v1.json
# Expected: 7-8 violations detected
```

**Estimated recovery time:** 4-6 hours

## Lessons Learned

### Documentation Principle Violated

**Principle:** "Explicit > Implicit"

**What we did (wrong):**
- Implicitly suggested sequence through day numbers (1, 2, 3)
- Implicitly suggested prerequisites through prose ("you'll need claims for scanning")
- Assumed readers would infer Day 1 must complete before Day 2

**What we should do (right):**
- Explicitly state "Complete Day 1 before Day 2" in bold/emoji
- Explicitly check prerequisite completion with automated script
- Explicitly block progression with "DO NOT PROCEED" checkpoint

### Agent vs Human Documentation

**New insight:** Agent interpreters need more explicit sequencing than humans.

**Human reasoning:**
> "Day 1 comes before Day 2, so I should probably do Day 1 first"

**Agent reasoning:**
> "Both sections are documented. I was told to 'go through every step' so I'll execute the implementation steps in Day 2"

**Implication:** Documentation for agent workflows needs:
- Explicit prerequisite statements, not implicit ordering
- Automated verification checkpoints
- Visual/textual blocking indicators (⛔, STOP, DO NOT PROCEED)

### The "Information Needed" Anti-Pattern

**Problem:** Day 2 heading says "Implementation - Information Needed"

**Team interpreted:** Reference material to consult

**Should have been:** "Implement Code with Intentional Violations"

**Learning:** Use action verbs in headings, avoid passive/reference tone

---

## Success Metrics (Post-Fix)

After implementing recommended fixes, next team should achieve:

**Day 1 Completion:**
- ✅ 25-30 claims created
- ✅ Verification command run successfully
- ✅ Checkpoint passed before Day 2

**Day 2 Execution:**
- ✅ Cannot proceed without Day 1 verified
- ✅ Implementation matches current team's quality
- ✅ Sequential workflow maintained

**Day 3 Scanning:**
- ✅ Scan detects 7-8 violations
- ✅ No confusion about why violations were detected
- ✅ Demonstration premise intact

**Time Saved:** 4-6 hours (no backfill needed)
**Blocker Prevention:** 100% (automated verification prevents sequence violation)
