What's New
AHP spec v0.9.0 defines automation, terminal states, and renames session lifecycle values
Breaking Changes
- Renamed failed session lifecycle value from `creationFailed` to `failed`.
- Removed `error` from `changeset/contentChanged`.
- Removed session-level forking from `createSession`.
- `TerminalSessionClaim` now requires the `chat URI`.
- Removed `ContentNotFound` error code.
New Features
- Added durable turn errors and resumable error handling via `chat/turnResume`.
- Added `InitializeResult._meta` for extension capabilities.
- Annotations now carry an `origin` with required session URI.
- Defined automation catalogue and self-contained event triggers.
- Terminal state now uses explicit `running`/`exited` lifecycle.
Improvements
- Generated clients now preserve unknown values for nonexhaustive protocol enums.
- Automation catalogue snapshots now use `AutomationState.entries`.
Upgrade Notes
Update session lifecycle checks to use `failed` instead of `creationFailed`. Ensure `TerminalSessionClaim` includes the required `chat URI`. Update `changeset` handling to replace `error` with `changeset/statusChanged`.
