New exact SHA (frozen): 7a387323bc8ad644fe93d6bbd7bf413e41565943
Branch: feat/pg-migrate-core
禁止合并 / 禁止部署。 请 bilinote-120 对本 SHA 复审。

P1-1 — destructive PG allowlist bypass via ?dbname=

Fixed (fail-closed).

• effective_database_name_from_dsn resolves path + dbname/database query; rejects empty values, duplicate/conflicting query params, and path≠query conflicts (the repro .../bilinote_core_test?dbname=bilinote_shadow is refused even though SQLAlchemy create_connect_args would choose shadow).
• Allowlist is only {bilinote_core_test}; bilinote_shadow remains forbidden.
• Live gate: assert_live_database_allowlisted runs SELECT current_database() and must match the same allowlist before any DROP SCHEMA (test_pg_migrate_postgres._reset_public_schema + scripts/run_pg_migrate_tests.py probe).
• normalize_target_identity now uses the effective dbname (not path-only).
• Regressions: ?dbname=shadow reject; path-only / same-name query OK; percent-encoded override; empty/database conflict; SQLAlchemy effective-dbname proof; error text uses redact_dsn (password not leaked).

P2-1 — knowledge_index_entries.task_id

Fixed. Added to SOFT_FK_EDGES → video_tasks.task_id (strict verify orphan audit). Explicitly not in INTENTIONAL_NON_REF_COLUMNS.

P2-2 — verify independent schema/FK introspection

Fixed. New app/migration/schema_introspect.py; verify_migration compares live public columns/nullability/type-kind, PK, unique, indexes (excl. PK-equivalent), and FK ondelete/onupdate against frozen FOUNDATION_METADATA, independent of Alembic revision. Drift → schema_drift errors (fail-closed).

Verification (this worktree)

• Targeted: test_pg_migrate_core + test_postgres_foundation + test_pg_migrate_postgres → 53 passed, 5 skipped (live PG skipped without DSN).
• Full backend pytest → 1220 passed, 5 skipped, exit 0.
• Live PG create/migrate/verify on Unraid still needs bilinote-117 secret-file run against this SHA (UNVERIFIED here).

@bilinote-120 please re-review exact head 7a387323bc8ad644fe93d6bbd7bf413e41565943 only. No merge.

Unraid PG17 evidence note (84dd56c) — does not close P1

Recorded for bilinote-90 / bilinote-117:

• Evidence dir: /mnt/disk1/appdata/bilinote-shadow/test-runs/pr53-84dd56cb7055dbbed3f356b849ef559300efeab2-live-20260904
• Run: exit 0; 25 passed / 0 failed / 4 skipped
• bilinote_core_test relations 43→43; Alembic foundation unchanged; formal bilinote_shadow 0→0

Interpretation: only proves the normal migrator DSN path is safe on PG17. It does not close review 5108763452 P1 (?dbname= override vs path-only allowlist).

P1 fix already shipped on frozen head: 7a387323bc8ad644fe93d6bbd7bf413e41565943
(effective dbname + SELECT current_database() fail-closed + query-override regressions; see prior comment).

禁止合并 / 禁止部署 until bilinote-120 re-reviews that new SHA. Live re-run on 7a38732 still welcome (secret-file / bilinote-117).
