Reading all 28 models against each other: 54 `x.isoformat() if x else None` / `x.isoformat()` expressions in 23 to_dict methods, in two guarded/unguarded wordings, become iso() from models/base.py — uniform, and a row read before flush serialises as null instead of raising. Rulebook / RulebookTopic / Rule carried byte-identical copies of TimestampMixin's two columns; InvitationToken / PasswordResetToken / NoteUsageEvent carried CreatedAtMixin's — all six now use the mixin. AppLog and RetrievalLog keep their explicit created_at, commented: their composite index orders on `created_at.desc()`, which needs the column object in the class body. Schema-neutral (same column definitions) — no migration. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
