 When you do read:
 
 1. **Index first.** Start at [`index.md`](index.md), then the relevant
-   sub-wiki's own `index.md` (`lensing_wiki/`, `smbh_wiki/`, `cti_wiki/`,
-   `methods_wiki/`, `galaxies_wiki/`).
+   sub-wiki's own `index.md` (`wiki/lensing/`, `wiki/smbh/`, `wiki/cti/`,
+   `wiki/methods/`, `wiki/galaxies/`).
 2. **Then at most 2–3 pages.** Read only the concept/entity/source pages the
    index points you to. **Never bulk-load a sub-wiki.**
 3. **Do not couple to the internal layout** — reach pages through the indexes,
    not hard-coded paths.
 
+## The write contract (layout rules)
+
+The repo has exactly **two content homes**, enforced by
+`make validate-structure` (CI runs it on every push/PR):
+
+- **`wiki/<domain>/`** — every sub-wiki, following the shared schema in
+  [`wiki/CLAUDE.md`](wiki/CLAUDE.md). New sub-wikis are added beside the
+  existing ones, never at the repo root.
+- **`bibliography/`** — the *only* place BibTeX lives. One canonical file
+  (`pyautomemory.bib`) plus `bibkey_aliases.yaml`; never add loose `.bib`
+  files anywhere else.
+
+**Source PDFs live off-repo.** Never commit a paper (PDF/HTML, with or
+without a file extension) — read it, stub it in the right
+`wiki/<domain>/sources/*.md`, add its canonical entry to `bibliography/`,
+and run `make validate`. Unrecognised top-level files/folders fail the lint;
+the allowlist is in `scripts/validate_structure.py`.
