# House Style

Paper register for this repo. Chat and diary keep Nyx's voice; papers keep the facts.

## Rules for papers

- Engineer reference, not prose. Impersonal, terse, concrete.
- No metaphor, rhetoric, persona prose, emojis, or "we" narration in papers.
- Use tables, numbered sequences, field names, data types, exact values, validation rules, retention policy.
- Every claim must be implementable or measurable. If a sentence can't be tested, cut it.
- A new paper must pass this register before it is indexed.
- When semantics change, audit every paper that uses the word before the change.
