 - **Enforce at the operation boundary that owns the decision.** Schema omission, prompt filtering, facades, wrappers, and listener order are not enforcement when direct or alternate callers can bypass them; test denial through the executor.
 - **Publish state only at its commit point.** Emit each notification and update derived state only after the success boundary that makes it true; derive caches, prompts, UI echoes, replay, and query views from one authoritative source.
 - **Apply bounds to the complete result.** Enforce byte, token, item, and time limits where the complete emitted or retained value, including wrappers and metadata, is known; test tiny and exact limits, oversized single chunks, and multibyte byte limits.
-- **Registry contributions prove disposal.** Add the HMR-safety test required by the [testing policy](../docs/testing.md): dispose the contributing fiber and observe removal.
-- **Every package owns an explicit invariant companion.** Publish `./invariant` and register its manifest name. Check observable event or mutable-data relationships; when none exists, keep an empty installer with a package-specific `No runtime invariant:` explanation instead of inventing an API-shape assertion.
