# Phase 0 §12A — scope boundary audit

**Tasks:** T038, T039, T042  
**Audited:** 2026-06-13

## T038 — Forbidden implementation tasks in tasks.md

Reviewed `specs/001-v8-phase0-preflight/tasks.md`.

| Check | Result |
|-------|--------|
| Any task modifies `src/stel/**` | **NONE** |
| Any task begins Phase 1 STEL implementation | **NONE** |
| Any task adds Phase 4 deploy/admin/AAP code | **NONE** |
| All tasks produce docs/research or validation artifacts | **PASS** |

**Verdict:** tasks.md scope is Phase 0 evidence-only.

## T039 — 7.x baseline non-gating

| Check | Result |
|-------|--------|
| Evidence set requires beating `results-7.21.1-baseline.json` | **NO** |
| Spec/plan mark 7.x as informational only | **YES** ([spec.md](../../specs/001-v8-phase0-preflight/spec.md), [ideation.md](../ideation.md)) |
| v8 gates are H1–H8 absolute on v8 corpus | **YES** |

**Verdict:** §12A item "No requirement to beat 7.21.1 baseline" **SATISFIED**.

## T042 — Git diff path audit (`src/stel/**`)

```text
git diff --name-only HEAD -- src/stel/
(no output — no tracked changes)

git status -- src/stel/
(no src/stel/ directory in working tree)
```

| Check | Result |
|-------|--------|
| `src/stel/**` files changed this feature | **NONE** |
| `src/stel/` directory exists | **NO** |

**Verdict:** pre-implementation boundary preserved for source tree.

## Forbidden paths (scope guard)

| Path / work | Status this feature |
|-------------|---------------------|
| `src/stel/**` | **NOT TOUCHED** |
| Phase 4 deploy/admin UI | **NOT IN SCOPE** |
| AAP convenience integration | **NOT IN SCOPE** |

## Product implementation stop report

No task in this execution required STEL product implementation. Blocked items (compact stub, sf-bench battery) are **external harness / non-shipping stub** work — deferred with explicit NO-GO blockers rather than silent skip.
