+This project has a knowledge graph at graphify-out/ with god nodes, community structure, and cross-file relationships.
+
+Rules:
+- For codebase questions, first run `graphify query "<question>"` when graphify-out/graph.json exists. Use `graphify path "<A>" "<B>"` for relationships and `graphify explain "<concept>"` for focused concepts. These return a scoped subgraph, usually much smaller than GRAPH_REPORT.md or raw grep output.
+- If graphify-out/wiki/index.md exists, use it for broad navigation instead of raw source browsing.
+- Read graphify-out/GRAPH_REPORT.md only for broad architecture review or when query/path/explain do not surface enough context.
+- After modifying code, run `graphify update .` to keep the graph current (AST-only, no API cost).

- * token's claims and reconciled against the user's MAPPING-OWNED state:
- *
- * - Pond grants are created and revoked through {@link GrantsService} —

- *   invalidated and live collab sessions are revalidated
- *   (`notifyAccessChanged` → the collab access listener) exactly as on a
- *   manual change. No raw row writes.
- * - The mapping only ever touches rows with `origin = 'idp'` and only
- *   demotes a site admin whose flag it itself set
- *   (`isSiteAdminManaged`) — **manual wins**: hand-made grants and
- *   hand-promoted admins are never revoked by a missing claim.
- * - Every change is audited (grant.created/grant.deleted with
- *   `origin: idp_mapping`; user.site_admin_set with the same marker).
- *
- * Reconciliation happens at login because that is when fresh claims
- * exist; between logins the leaver case is the IdP's (disable there =
- * no new login) plus the operator's account-disable flag.
