## Pre-Build Gate

**Verdict: PASS**

**Gate assessed:** 2026-04-05 (assessment #8 — independent verification)
**Mission:** token-monitor-phase2 (trentuna/token-monitor#1)
**Assessor:** Amy Allen

### What I checked

**Note:** B.A. has already completed the build (commit `34898b1`). This assessment confirms the pre-build gate conditions were met *and* independently verifies the deliverables against the spec.

#### Pre-build readiness (retroactive confirmation)

1. **Objective clarity:** ✅ Forgejo #1 specifies four deliverables with operational outcomes: cache guard, analyze.js with six subcommands, log hygiene with prune, rotation algorithm. Each has specified behavior and output format.

2. **Success criteria testability:** ✅ Five concrete, automatable assertions specified in the architecture:
   - `node analyze.js` exits 0 with non-empty output — **verified**
   - `node analyze.js --rotation` outputs ranked list — **verified (5 providers ranked)**
   - Cache guard: consecutive runs within 20min use cached data — **verified (getCachedRun in logger.js)**
   - `node analyze.js --prune --dry-run` reports without deleting — **verified**
   - `node test.js` passes — **verified (162/162 green)**

3. **Recon completeness:** ✅ No external unknowns. All data sources are local JSONL files (181KB across 2 days — sufficient). No Face recon needed.

4. **Role assignments:** ✅ Explicit in issue #1. Hannibal: architecture. B.A.: implementation. No agent-affecting changes.

5. **Brief quality per mission-standards.md:**
   - [x] Objective describes operational outcome (trend-line intelligence, not just "a script")
   - [x] Success criteria are testable assertions (5 concrete checks)
   - [x] Role assignments name who does what
   - [x] No agent-affecting changes requiring self-verification

#### Build verification (bonus — since it's already delivered)

All four deliverables confirmed functional:
- **Cache guard:** `getCachedRun(maxAgeMinutes=20)` in logger.js, integrated into monitor.js
- **analyze.js:** 546 lines, six subcommands (burn-rate, weekly, stagger, rotation, prune, full report), JSON output mode
- **Log hygiene:** `--prune` and `--prune --dry-run` implemented
- **Rotation algorithm:** Rule-based ranking by headroom, invalid keys deprioritized, maxed accounts sorted by reset time

### Outstanding items

None. The spec was clean, the build matches it, and all success criteria pass.

*Triple A reporting. The pre-build gate was already passed in assessment #7 and the build is complete. Independent verification confirms: spec was unambiguous, success criteria were testable, and all five pass. PASS.*
