Never pay a model for what a script can do.
A stale code atlas regenerates with no model call at all. A failing suite re-runs locally before an agent is spawned. A
4xx aborts immediately instead of retrying across six models. Retrying a bad key just spends the budget six times to learn the same thing.

Determinism is three problems, not one.
mulberry32 in pure int32 space so state transitions never touch floats. Per-shape sub-seeds from distinct primes. Coordinates pinned to 6 decimals before emission. 465 tests, one proving a shape stays byte-identical when its sibling changes.

Constraints belong in the database.
One caption per user via a
partial unique index, so replies stay unaffected. Idempotent closure through UPDATE … RETURNING id, false on zero rows. Decaying-score leaderboard as a four-stage CTE over window functions.
