## [Unreleased]

## [0.2.0] - 2026-11-01

### Added

- Durable outbox: records are fsynced under `~/.pi/agent/delta-db/outbox/` before Delta is
  contacted, and a failed append is retried on the next message and the next session start.
- Thoughts, tool calls, and tool results are recorded, not only message text.
- `/delta off` and `/delta on` are remembered for the session.
- Bindings whose session file is gone and that have not been touched for a week are pruned.
- Tests for record shapes, sequence assignment, outbox retry, and pruning (`npm test`).
- CI runs `npm run check` and `npm test` on every push.
- npm publish workflow: a published release publishes to npmjs.org when `NPM_TOKEN` is set.
- GitHub Packages mirror: `.github/workflows/publish-github-packages.yml` publishes
  `@morizkay/pi-delta-db` on every published release, populating the repository's Packages tab.
  npmjs.org (`pi-delta-db`) remains the installable channel.

## [0.1.0] - 2026-11-01

### Added

- `delta_store` tool: append text to this session's private Delta thread, with optional
  `title` and `role`.
- `delta_read` tool: list threads, search thread text, or show one transcript.
- `delta_db` tool: read-only inspection of Delta's local store (`stats`, `root <id>`).
- Automatic recording: every finalized user and assistant message is appended to the
  session's Delta thread in order, with the thread created on first use and titled from
  the first prompt.
- `/delta` command: show recording state, thread id, title, and share URL; `/delta on|off`
  toggles recording for the session.
- `PI_DELTA_RECORD=0` to start Pi with recording disabled.
- Writes are serialized through one queue and take their sequence from `delta thread status`,
  so concurrent appends cannot reuse a sequence.
- Recording failures warn once per session and never interrupt a Pi turn.

### Fixed

- A repeated `messageId` made Delta replace earlier records, silently erasing previous turns
  in a continued session. Message ids are now unique per message.
- `session_info_update` re-titled the thread on every continuation. The title is now written
  once and remembered in the session binding.
