# Gap Analysis

**Timestamp:** 2026-02-09T21:22:00Z
**Phase:** Day 1 - Corpus Building
**Critical Finding:** 0 claims created (expected 25-30)

---

## Gap 1: Unclear Day 1 Completion Criteria

**Type:** Missing Information

**Evidence:**
- **Team thought (progress log):** "Where You Are: Day 1, Step 3 (creating claims in corpus)"
- **Team did (implementation review):** Created 3 source documents, config file, code placeholder, but 0 claims
- **Doc said (CHECKLIST.md:103-159):** Shows "Day 1: Corpus Building - Information Needed" section with source document instructions

**Root Cause:**
Documentation presents Day 1 as "Information Needed" with source documents as primary deliverable, burying actual claim creation workflow further down. Team interpreted "Day 1" as "fetch the information" not "create 25-30 claims."

**Evidence from CHECKLIST.md Structure:**
```
Line 103: ## Day 1: Corpus Building - Information Needed
Line 105: ### 📖 Learn Claim Extraction First
Line 124: ### 📚 Authority Source Documents  ← Team stopped here
Line 155: ### 🔧 Aphoria CLI Usage               ← Actual work buried below
Line 157: - [ ] **How to create claims**
```

**Impact:**
- Time lost: Unknown (team hasn't completed Day 1)
- Confusion level: High (team thinks they're "ready to proceed")
- Blocker: Yes (cannot proceed to Day 2 without claims)

**Recommendation:**
- **Where:** CHECKLIST.md:103-104
- **What to add:**
  ```markdown
  ## Day 1: Corpus Building

  **Deliverable:** 25-30 claims created via CLI and verified in corpus database

  **Success Criteria:** Run `curl 'http://localhost:18180/v1/aphoria/corpus?sources[]=vendor' | jq '.items | map(select(.subject | startswith("dbpool"))) | length'` and see 25-30

  **Estimated Time:** 4-6 hours
  ```
- **Priority:** High (blocker for Day 2+)

---

## Gap 2: "Information Needed" Implies Preparation, Not Execution

**Type:** Unclear Instructions

**Evidence:**
- **Team thought:** "Ready to Execute: Yes, but run the validator first" (implies they think prep is done)
- **Team did:** Fetched source docs, created config, stopped
- **Doc said (CHECKLIST.md:103):** "Day 1: Corpus Building - **Information Needed**"

**Root Cause:**
"Information Needed" heading implies "here's what you need to gather" not "here's what you need to DO." Team interpreted this as prerequisite gathering phase, not execution phase.

**Impact:**
- Time lost: Moderate (team waiting for next instruction)
- Confusion level: High (team believes Day 1 is complete)
- Blocker: Yes (Day 1 actually incomplete)

**Recommendation:**
- **Where:** CHECKLIST.md:103
- **What to change:**
  ```markdown
  # BEFORE:
  ## Day 1: Corpus Building - Information Needed

  # AFTER:
  ## Day 1: Create 25-30 Corpus Claims

  **What you're doing:** Extract claims from authority sources and create them via CLI
  **How long:** 4-6 hours
  **Done when:** `curl ...` returns 25-30 claims
  ```
- **Priority:** High (misleading heading causes confusion)

---

## Gap 3: Source Document Fetching Gets Checkboxes, Claim Creation Doesn't

**Type:** Buried Information

**Evidence:**
- **Doc structure (CHECKLIST.md:126-153):** 3 checkbox items for source documents
- **Doc structure (CHECKLIST.md:157-180):** Claim creation is prose explanation, no checkboxes
- **Team did:** Completed all checkbox items (source docs), skipped prose section

**Root Cause:**
Checkboxes signal "this is the task." Prose without checkboxes signals "this is reference information." Team followed checkboxes, ignored prose.

**Impact:**
- Time lost: Moderate (incomplete Day 1)
- Confusion level: Medium (checkboxes are powerful psychological signals)
- Blocker: Yes (claim creation is the actual Day 1 work)

**Recommendation:**
- **Where:** CHECKLIST.md:157-200
- **What to add:** Convert claim creation into checkbox format
  ```markdown
  ### ✅ Create Corpus Claims (25-30 total)

  - [ ] **Safety Claims (10 claims)**
    - [ ] Create `dbpool/max_connections` required claim
    - [ ] Create `dbpool/min_connections` min_value claim
    - [ ] ... (all 10 listed)

  - [ ] **Performance Claims (8 claims)**
    - [ ] Create `dbpool/max_connections/development` default_value claim
    - [ ] ... (all 8 listed)

  - [ ] **Security Claims (5 claims)**
    - [ ] Create `dbpool/connection_string/password` must_not_be claim
    - [ ] ... (all 5 listed)

  - [ ] **Architecture Claims (4 claims)**
    - [ ] Create `dbpool/health_check/endpoint` required claim
    - [ ] ... (all 4 listed)

  - [ ] **Verify claims created**
    ```bash
    curl 'http://localhost:18180/v1/aphoria/corpus?sources[]=vendor' | \
      jq '.items | map(select(.subject | startswith("dbpool"))) | length'
    # Expected output: 25-30
    ```
  ```
- **Priority:** High (critical workflow gap)

---

## Gap 4: Claim Extraction Example Not Integrated into Workflow

**Type:** Buried Information

**Evidence:**
- **Team thought (progress log):** "✅ claim-extraction-example.md teaches the critical distinction between observations vs claims with full worked examples"
- **Team did:** Read the example (acknowledged it), but didn't use it to create actual claims
- **Doc said (CHECKLIST.md:105-120):** "Before creating claims, read the complete walkthrough"

**Root Cause:**
Example is presented as "read this first" but not integrated into execution workflow. No step says "Now use this example to create your first 3 claims following the same process."

**Impact:**
- Time lost: Low (example was read and understood)
- Confusion level: Low (example is clear)
- Blocker: No (team understands concepts, just didn't execute)

**Recommendation:**
- **Where:** CHECKLIST.md:120 (after claim extraction example)
- **What to add:**
  ```markdown
  **Now apply this:** Create your first 3 claims following the same reasoning process:

  - [ ] **Claim 1:** Extract from HikariCP "Small Pool Philosophy" paragraph
  - [ ] **Claim 2:** Extract from PostgreSQL "300-500 connections optimal" empirical result
  - [ ] **Claim 3:** Extract from OWASP "plaintext passwords prohibited"

  Use the same structure as the walkthrough: identify claimable statements → reason about WHY → write explanation with WHAT/WHY/CONSEQUENCE → submit via CLI.
  ```
- **Priority:** Medium (bridges example to execution)

---

## Gap 5: No "You Are Here" Progress Indicator

**Type:** Missing Information

**Evidence:**
- **Team thought:** "Where You Are: Day 1, Step 3 (creating claims in corpus)"
- **Team did:** Fetched sources (Step 1), read example (Step 2), stopped before Step 3
- **Doc structure:** Days are clear, but steps within days are not numbered

**Root Cause:**
Team self-identified as "Step 3" but docs don't have explicit step numbers. No way to confirm "am I done with Day 1?" without reading entire section.

**Impact:**
- Time lost: Low (self-assessment was close)
- Confusion level: Medium (team unsure if Day 1 complete)
- Blocker: No (team can figure it out, just slower)

**Recommendation:**
- **Where:** CHECKLIST.md:103-200
- **What to add:** Add step numbers
  ```markdown
  ## Day 1: Create 25-30 Corpus Claims

  **Step 1:** Read claim extraction example (15-20 min)
  - [ ] Read `docs/claim-extraction-example.md`

  **Step 2:** Fetch authority source documents (30 min)
  - [ ] HikariCP
  - [ ] PostgreSQL
  - [ ] OWASP

  **Step 3:** Create corpus claims (3-4 hours)
  - [ ] Create 25-30 claims via `aphoria corpus create`

  **Step 4:** Verify completion (2 min)
  - [ ] Run verification: `curl ...`
  - [ ] Confirm: 25-30 claims found

  ✅ **Day 1 Complete** when verification shows 25-30 claims
  ```
- **Priority:** Medium (improves clarity)

---

## Non-Gaps (Correct Team Actions)

### Action 1: Created `.aphoria/config.toml` Early

**Doc said (CHECKLIST.md:250-265):** "Create `.aphoria/config.toml`" (Day 3: Scanning section)

**Team did:** Created config file during Day 1

**Analysis:** NOT A GAP
- Config file is correct (ephemeral mode, thresholds match docs)
- Creating early is actually helpful (ready for Day 3)
- Shows proactive project setup behavior (positive)
- No negative impact

### Action 2: Created `src/lib.rs` Placeholder

**Doc said (CHECKLIST.md:164-242):** Implementation code is Day 2 deliverable

**Team did:** Created 5-line placeholder with intentional violation (`Option<usize>`)

**Analysis:** NOT A GAP
- Minimal placeholder, not full implementation
- Contains intentional violation (matches plan)
- Creating early doesn't block Day 1 completion
- Shows forward-thinking preparation (positive)

## Summary

### Documentation Gaps Found: 5

| Gap | Type | Priority | Impact |
|-----|------|----------|--------|
| 1. Unclear completion criteria | Missing | High | Blocker |
| 2. "Information Needed" misleading heading | Unclear | High | Blocker |
| 3. No checkboxes for claim creation | Buried | High | Blocker |
| 4. Example not integrated into workflow | Buried | Medium | Confusion |
| 5. No step numbers within days | Missing | Medium | Slowdown |

### Team Errors: 0

Team followed documentation structure exactly. They completed every checkbox item presented. The issue is documentation structure, not team execution.

### Root Cause Pattern

**The Problem:** Day 1 section structured as "reference information" not "execution workflow"

**Evidence:**
- Heading: "Information Needed" (implies prereqs, not work)
- Checkboxes: Only for source docs (fetching), not claims (creating)
- Example: Positioned as "read first" not "now do this"
- Verification: Buried at bottom, not emphasized as completion gate

**Fix:** Restructure Day 1 as execution checklist with clear deliverable (25-30 claims) and success criteria (verification command).

---

## Impact Assessment

**Current State:**
- Team believes Day 1 is complete (90% understanding)
- Actually: 0% complete (0/25-30 claims created)
- Estimated time to complete: 3-4 hours (claim creation)

**If Documentation Had Been Clear:**
- Team would have created 25-30 claims
- Day 1 would be complete
- Ready to proceed to Day 2 (implementation)

**Documentation Success Rate:**
- Source fetching: 100% (3/3 completed correctly)
- Claim creation: 0% (0/25-30 completed)
- Overall Day 1: 10% complete

**Cold-Start Success Estimate Revision:**
- Original estimate: 85-90%
- Actual observed: ~10% (stopped after source docs)
- Gap: Documentation structure implies wrong completion criteria
