5 plans across 5 sequential waves covering: Alembic migration 0003 (null-user
cleanup, NOT NULL constraint, quota reconciliation), presigned MinIO PUT upload
flow with atomic quota enforcement, auth guards on all document/topic endpoints,
flat-file settings retirement + per-user AI classification, and frontend quota bar
with 3-step XHR upload progress.
Verification passed across all 12 dimensions. All 8 phase requirements covered
(STORE-03/04/05/06, SEC-04, DOC-03/04/05).
