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
