Repo Architecture — Filing Rules

> **Full filing rules:** See `skills/_brain-filing-rules.md`

Contract

This skill guarantees:

• Every new page is filed by primary subject (not format, not source)
• The decision protocol is followed for ambiguous cases
• Common misfiling patterns are caught

Phases

1. **Identify the primary subject.** What would you search for to find this page? 2. **Walk the decision tree:**

• About a person → `people/{name-slug}.md`
• About a company → `companies/{name-slug}.md`
• A reusable concept/framework → `concepts/{slug}.md`
• An original idea → `originals/{slug}.md`
• A meeting → `meetings/{slug}.md`
• Media content → `media/{type}/{slug}.md`
• Raw data import → `sources/{slug}.md`

3. **Cross-link.** Link from related directories. 4. **Check notability.** See `skills/conventions/quality.md` notability gate.

Output Format

Advisory: "File this at `{type}/{slug}.md` because the primary subject is {reason}."

Anti-Patterns

• Filing by format ("it's a PDF so it goes in sources/")
• Filing by source ("it came from email so it goes in sources/")
• Creating pages without checking if one already exists
• Using `sources/` for anything except raw data dumps
