fred ee8c593858 docs: hierarchy schema contract revision 2 (terra review findings 1-9) ...

- tenancy-FK exemption: canonical workspace_id is the one permitted
  business->class reference; all other forms forbidden with control test
- record class = 4 node tables + hierarchy_grants per A1 8.1.2
- grant uniqueness via UNIQUE NULLS NOT DISTINCT (or 6 partial indexes);
  NOT NULL on role/granted_by/name/slug
- grant FK delete actions split: target cascade, principal RESTRICT
- audit parity: REQ-AUD-001 guarantees, same-transaction outbox,
  deletion-safe snapshot linkage, cascade coverage, rollback witness
- roll-up never-a-write restored to full A1 strength (no canonical writes)
- ownership invariant completed via contract 2; both-sides transfer rule
  marked new policy; legacy premise corrected
- corrected cardinality witness (one-parent-per-child + sibling control)
- provenance fixes: REQ-MIG-001 attribution dropped, projects table
  described accurately, D8-rank-1 claim removed
