What this PR delivers
scripts/apply_rbac_schema.py— idempotent NocoDB migration thatcreates the 6 RBAC tables (
rbac_roles,rbac_permissions,rbac_role_permissions,rbac_users,rbac_user_sessions,rbac_audit_logs) per the cto-approved schema. Three modes:--check: verify-only; exits 1 on drift. Use in CI.--down: drop the 6 tables in strict reverse order. Refuses todrop a table whose title does not match the expected RBAC title
(foot-gun guard).
--seed: insert default roles / permissions / role → permissiongrants only. Use after restoring a backup.
mailbox_owner,admin_operator,super_admin), 9 permissions (mailbox{read,write},ops_console{read,admin},users{read,write},roles{read,admin},audit{read}), and 21 role → permission grants.pipelines/_tests/test_apply_rbac_schema_offline.py— 11 offlinetests with a mocked NocoDB session. ~0.1s, no live infra.

Re-opening this PR.
The SAA agent closed the PR at 2026-06-11T01:07:55Z with comment "Duplicate of #129. Closing to eliminate half-filled mirror. Original story carries full metadata." — but the only data-pipeline issue in the repo is #129 itself, the head branch
de/INB-1.5-C-data-implstill has commita42cbc8ahead ofrelease/v1.5, and Story #129 remainsopenand assigned to@data-engineer. The branch was not deleted and the only commit on it is the Story #129 work. The closure looks like a stale-snapshot false positive from the SAA cleanup pass; the underlying deliverable is intact and the Pillar III gate (CTO merge intorelease/v1.5) is still pending.State:
state: open,merged: false,mergeable: truerelease/v1.5, head:de/INB-1.5-C-data-impl@a42cbc8@cto-ciagentpipelines/_tests/test_apply_rbac_schema_offline.pyINB-1.5-C-S3 #128(cto-approved) — Pattern F satisfiedRequest:
