scope-lock
A called pass. Only run it when you have asked for it.
Status: Locked. Same-session validation, including a run that failed by inventing nouns.
A scope lock is a short written contract. The value concentrates in the non-goals list: the part people skip, and the part that prevents drift.
Use when you ask to lock scope, freeze requirements, or write a contract for what is in and out. Do not use unprompted, or while the problem is still being found.

Protocol
- Restate the problem in one sentence, using only nouns already on the table. If you cannot, stop.
- List what is explicitly not being solved. If a reader could assume it is in, and it is not, it belongs here.
- Define done as an observable condition, not a feeling. Do not demand numbers the user did not state.
- Name what would justify reopening scope: a trigger, not a vibe.
- Hand back the artifact (Problem / In / Not in / Done / Reopen if) and stop.
If the input is too soft, do not produce a full-dress contract of nothing.
