1.1 Naming

Every documented file and folder is kebab-case: lowercase letters, digits,
hyphens. No spaces, no capitals, no underscores.

✓ standard-vault.md      ✓ reference/
✗ Standard-Vault.md      ✗ Story/        ✗ ATLAS.md

Why this is a norm, not a taste

• A name you can guess is a name you can open, grep, and link without
  looking it up.
• Case-sensitive filesystems (Linux, some CI) treat Story/ and story/ as
  different folders; the norm removes the entire class of bug.
• URLs derive from filenames; kebab-case names are already valid slugs.

Exceptions

Machine-required names keep their required casing (README.md, LICENSE,
CLAUDE.md) — these are protocols, not documents.
