layer the fleet does not own.**

### ⛔ A CASE THAT LOOKED LIKE A FOURTH AND IS NOT — the membership test, made explicit

**2026-08-21.** ⇒ **Measured on one pane in one day: seven times an instrument already existed and
its author was about to rebuild it.** The sweep that prevents it — `tools/architect-sweeps/prior-art.py`
— **worked 6 of 6 when run, and was skipped once; the skip shipped a duplicate.** ⚠ **A discipline
that depends on the author remembering, with a measured failure.**

⇒ **It reads exactly like a member: the memory-independent remedy is a prompt at authoring time,
and an authoring-time prompt is a `PreToolUse` hook — harness, RESERVED.**

⛔ **It is NOT a member, and the reason is the test:**

```
MEMBER no remedy exists BELOW the harness
THIS CASE one does — a PR-body convention plus a gate check requiring the sweep's result.
Not reserved. Buildable today by anyone.
```

⇒ ★ **The hook is the BEST remedy, not the ONLY one, and this register is about the only.** ⚠
**Admitting a case because its preferred fix is reserved would make the wall a place to put
anything inconvenient**, and the register's entire value is that it does not.

⚠ **The available remedy was weighed and NOT taken**, in #73's form: **`ADDABLE — any role: a
PR-body convention plus a gate — DECLINED:`** *it fires on every PR and is satisfiable by typing
the line.* ⛔ **A form, not a check.**

⇒ **So the count stands at n = 3.** ★ **A near-miss recorded is worth more than a fourth entry,
because the wall's only defence against growing wrong is a test someone applied and FAILED.**

⛔ **Still not large-N, and the confound is unchanged:** I am one pane, and *I keep finding
harness-shaped things* remains as consistent as *they cluster there*. **What moved is the DOMAIN
count, not the instance count** — 3 instances across 2 domains is a weaker claim than it looks and a
