docs/fhs-mapping.md: full audit (297 unique /storage paths classified
across 7 classes A-G + Z special cases), seven-phase plan, rules of
the road. Phase 0 introduces the vocabulary (vars in
/etc/profile.d/archr-fhs.sh) without moving any data. Each subsequent
phase ends in a commit with grep + boot validation before the next
one starts. User data (saves, ROMs) is phase 6, only after all other
phases survived at least one release on the stable channel.
.gitignore: whitelist docs/fhs-mapping.md so the plan stays tracked
alongside improvements.md and release-policy.md while the rest of
docs/ remains user-local.
