/**
* Derived-message cache tests: the session projects each surface node exactly
* once (O(new nodes) per call), rebuilds on a surface replacement (the
* replaceGeneration signal), returns a fresh array snapshot
* per call over shared frozen messages, and stays deep-equal to a from-scratch
* replay derivation at every step — the incremental==scratch property the
* reconstructability RFC's invariant enforces in dev at request time.
* Derived-message cache contract against a scratch oracle: project new nodes
* once, rebuild on surface replacements, return fresh arrays over shared
* frozen messages, and remain value-equal to replay at every step.
