So a session or agent that creates or edits documentation does it consistently
with the corpus, not against it. Codifies what the migration learned, each rule
tied to the failure it fixes:
1. Link the canon, never copy it (the anti-drift law — "7 families" survived in
three docs because they re-transcribed instead of linking).
2. Every doc belongs to one stratum (E0-E5 / process); where each kind lives.
3. Reference docs are timeless — hand-offs, dated status and hardcoded catalogs
go to process/ or become pointers.
4. One source per concern; two docs on a subject get distinct stated roles.
5. Frontmatter convention.
6. Sections cited by §N are load-bearing — stub-split, never silently renumber;
verify moved links resolve.
7. English target; code comments always English.
8. Naming (rfc-* / design-*), markdown relative links, pre-commit checklist.
Wired into docs/README.md ("I want to… write a doc" + a note after the strata).
