0.20.0

Fixed

• An Eventlog store handle builds its verified model once per head instead of once per call. Every read, preflight, recovery and post-commit check still takes a fresh complete capture; a capture identical to the one last verified reuses its model, a capture that only adds the events this handle committed advances the model by those records, and any other capture — another writer's head, or a changed blob, event or projection row — is verified whole as before. A committed batch takes three captures instead of four: the append's recovery capture also supplies the expected heads. Canonical encoding no longer clones each subtree once per level of nesting. Canonical bytes, receipts and every refusal are unchanged.

Added

• StoreCalls also counts model_builds, model_advances and records_decoded, and entity_store::asynchronous::verify_subject_history_extension verifies only the records a subject history gained after an already verified prefix.
