Changelog #

1.0.0 #

First release.

Typed collections over a CRDT store: put, get, delete, watch, and indexed queries with keyset pagination and live watching.
Deterministic merging by hybrid logical clock, with per-field CRDT types (LwwRegister, OrSet, PnCounter) declared through a merge strategy.
A SQLite storage engine with SQLCipher encryption at rest (verified on open), transactional schema management, corruption recovery from periodic snapshots, and an in-memory engine for tests.
A binary wire protocol (version 1) with a fail-closed decoder, streamed bounded sync frames, periodic anti-entropy, and range-fingerprint reconciliation that finds any gap in a few round trips.
Device membership: a per-device keypair port, a synced device roster with Ed25519-signed rows, pairing over a PAKE code, revocation with group-key rotation, a forward-secrecy ratchet per connection, and an opt-in recovery phrase.
Two library surfaces: package:passnote/passnote.dart (frozen app-facing API) and package:passnote/engine.dart (advanced wiring, engine and transport implementations, conformance suites). See VERSIONING.md.
