# L4 live-adapter validation — Fusion 2704.1.53

**Date:** 2026-09-05
**Fusion:** 2704.1.53 · **Python:** 3.14.0 · **Platform:** macOS x86_64
**Method:** `python3 tools/fusion_exec.py tools/probes/<probe>.py`

Per CLAUDE.md section 11, L4 cannot run on shared CI (Fusion is GUI-only and licence-bound),
so this record stands in for it. Every probe below is tracked and re-runnable verbatim, which
is what makes `[OPEN-6]` (Windows) and `[OPEN-7]` (Apple Silicon) parity cheap to establish
later — re-run these eight files and diff the output.

## Probes

| Probe | Covers | Result |
|---|---|---|
| `p01_environment.py` | version, interpreter, environment | recorded |
| `p02_fixture_corpus.py` | programmatic fixture corpus (PRD 13.2) | recorded |
| `p03_api_facts.py` | the 11 CLAUDE.md section 6 facts, C1–C11 | **22 verdicts, 0 REFUTED** |
| `p04_entity_token.py` | `[OPEN-1]` token durability | RESOLVED POSITIVE |
| `p04b_state.py` | sandbox census and cleanup | clean |
| `p05_curvature_seams.py` | `[OPEN-3]` curvature at seams | RESOLVED POSITIVE |
| `p06_texture_coordinates.py` | `[OPEN-8]` textureCoordinates | RESOLVED POSITIVE (5-face corpus) |
| `p08_cone_parameterization.py` | R-F1 Finding 13, cone parameterization | `tan` form REFUTED |

## Outcome

- **0 refuted** among the re-confirmed section 6 facts.
- **2 refined** — the cylinder `v` window is per-face, not an invariant (PRD 7.14); the
  `entityToken` 316-character figure is not stable.
- **2 refuted** — PRD 6.0 v1's cone `tan` form and PRD 11.8 v1's `u = z_rel/radius`.
- **3 new stub/runtime divergences** (PRD 11.14, CLAUDE.md section 5).
- Timings are recorded as **ranges, not constants**: cloud settle 2.9–5.3 s,
  `deleteMe()` listing lag up to 95.4 s.

Full evidence and per-claim numbers: **PRD sections 11.14 and 11.15**, and the commit bodies
on `test/live-fusion-recon` (merged at `c27cdbf`).
