Discovered by #47: the event cache stores wire envelopes (§9, D26) and live events decrypt on the change bus, but consumers reading cached history (offline scrollback, cold start, room-list last-event previews) have no decrypt path — §10.6.5's 'consumers decrypt via the machine path' has no public surface. Add suspend fun KatrixSession.decryptCached(roomId, raw: RawEvent): CommittedEvent delegating to the existing decorate logic (same UTD accounting, CR-8; plaintext passthrough as EventCryptoState.None). D30 executing choice.
