# Changelog

## [0.2.2] - 2026-08-13

### Changed
- Atomic conversation metadata: prism_sessions.version (migration 008, backfilled to 1) and appendSession expectedVersion CAS (0 = create-only, N>0 = exact-version update, omitted = last-write-wins); stale writes throw SessionMetadataConflictError metadata_conflict; concurrent create/branch/archive are single-statement and retention-deleted rows are never resurrected. See docs/migration.md and docs/conversations.md.

## [0.1.0] - 2026-08-09

## [0.0.26] - 2026-08-06

### Added
- Root re-exports `createPostgresAgentEventSource`, `ClosablePostgresAgentEventSource`, and `PostgresAgentEventSourceOptions` (FR-6) — the durable `AgentEventSource` is now importable from the package root without a `dist/...` subpath; `persistence.events` remains the canonical bundled path, unchanged.

### Changed
- Placement answer (FR-7): the durable event source stays in this package for the 0.0.26 line; PostgreSQL `LISTEN`/`NOTIFY` remains the reference durable implementation. See [agent events](../../docs/agent-events.md).

### Changed
- Publishable graph remains **47** manifests at **0.0.24**; peers and lockfile move together.

## [0.0.6] - 2026-07-19

### Changed

- Advisory-locked startup now validates SHA-256 migration history and complete schema-v3 metadata before writes; complete legacy `NULL` checksums backfill transactionally after shape verification, while drift fails closed.

- Initial `@arnilo/prism-session-store-postgres` release: `createPostgresPersistence` implements `SessionStore`, `RunLedger`, and `ProductionPersistenceStore` over `pg@^8.22.0` with versioned migrations, advisory-lock setup, parameterized SQL, configurable schema, and full conformance coverage (opt-in live PostgreSQL).
- Added persistence-owned generic `CheckpointStore` as `persistence.checkpoints`.
- Added atomic database-clock `LeaseStore` as `persistence.leases`, with opaque claims and monotonic fencing.

## [0.0.3] - 2026-07-14
