0.8.2

Performance

• File and PostgreSQL: a handle hashes each distinct blob content once, as SQLite already did,
  instead of on every read. EventStore::get_blob and every callback's ProjectionStore::get_blob
  still read the bytes from storage on each call and accept them without SHA-256 only when they
  equal, in full, content the handle verified or hashed while writing under the same hash; any
  other bytes are hashed and refused on a mismatch, so content changed after a verified read is
  refused on the next read through the same handle. A guard that reads a batch blob once per member
  of an M-member batch now pays one hash instead of M. The memory is the new provider-neutral
  eventlog_core::VerifiedContent (32 MiB per handle, cleared on blob deletion, tenant erasure
  and a failed blob-binding write), which SQLite now uses unchanged in behaviour. Nothing persisted
  changes.

Fixed

• ess/effects validates on ess 0.56.0: the EffectBoundaryCoverage invariant that one of
  records_terminal and records_incomplete holds is written with structured any:, since the
  compact predicate form has no or. The condition is unchanged.
