Prod smoke revealed the chain is PER-RLS-SCOPE, not global: audit_chain_hash()
trigger's prev-SELECT obeys each table's RLS policy under the inserting tenant's
GUC. On dev (superuser) it sees all rows (global chain); on prod (crm_app_user)
only RLS-visible rows (per-tenant chain). tenant_operations_log false-broke at a
tenant boundary (row 32, tenant 4 after tenant 3 rows).
Fix (stakeholder choice: per-scope validator, no trigger change / no hash rebuild):
- recompute now LAG OVER (PARTITION BY <scope> ORDER BY id):
tenant_id for tenant_operations_log/activity_log/balance_transactions/pd_processing_log;
(actor_type, tenant_id) for auth_log (RLS also filters actor_type='tenant_user');
global for saas_admin_audit_log (no tenant RLS — crm_admin_user BYPASSRLS sees all).
- exit code: incident write now best-effort (try/catch); ANY breach → self::FAILURE
regardless of whether incident row could be written (no active saas_admin FK).
Tests 7/7 (+multi-tenant per-tenant regression that reproduces prod chaining,
+exit-code-without-admin). Console 21/21, pint clean, larastan 0.
