# A-030 — Phase crosswalk review

**Task:** T040  
**Reviewed:** 2026-06-13

## Scope

Verify phase numbering alignment across:

- `docs/README.md` (canonical crosswalk table)
- `docs/v8-master-plan.md` phase sections
- `docs/stel-assumptions.md` phase gates table
- `docs/v8-gap-closure-plan.md` §12A/§12B split

## Crosswalk (README.md canonical)

| Master plan | stel-architecture | Delivers |
|-------------|-------------------|----------|
| **0** | Phase 0 | Harness trust, L0 A/B, pre-flight §12 |
| **1** | Phase 1 | Compact surface **H1** |
| **2** | Phase 2 | Router + controller **H3, H4, H5** |
| **3** | Phase 3 | Ledger → **8.0.0** + pin v8 baseline |
| **4** | Phase 4 | **H6, H8** + `symforge serve` + **O1–O8** → **8.1.0** |

## Findings

| Check | Result |
|-------|--------|
| README ↔ stel-assumptions phase gates | **PASS** — same 0–4 numbering |
| README ↔ v8-master-plan | **PASS** — no drift detected in phase labels |
| §12A vs §12B boundary | **PASS** — 12A blocks `src/stel/`; 12B blocks Phase 4/8.1 only |
| A-030 gap register (G-030c) | **NO-OP** — crosswalk consistent; no doc update required |

## Drift

**None.** Phase crosswalk is aligned.

## Required doc updates

None for A-030.

**§12A "Phase crosswalk reviewed (A-030)":** **ACCEPTED**
