v0.3.0

[0.3.0] — 2026-07-20

Added

• Semantic turn transcripts: Persist complete prompts, assistant messages, tool activity, plans, usage, stop reasons, and interrupted turns instead of token-level streaming events.
• Offline-first session history: Opening a .session renders its local transcript before any ACP process is initialized, even when the original working directory is unavailable.
• Explicit continuation workspace: Added read-only, ready-to-continue, connecting, connected, and backend-unavailable states with separate Continue and Start session actions.
• Crash-resilient persistence: Added atomic active-turn checkpoints, corrupt-record diagnostics, retryable persistence errors, and content-addressed blobs for large tool output.

Changed

• Version 2 session entries: Session entry identity, local history identity, and optional opaque ACP binding are now independent and stable.
• Continuation behavior: Opening a session never automatically loads, resumes, or creates an ACP session; continuation requires an explicit user action.
• History representation: Local transcript storage is now the single authoritative semantic history and no longer preserves streaming chunk timing.

Removed

• Development v1 compatibility: Removed v1 .session and raw SessionUpdate history readers, migration paths, and legacy projection. Development v1 sessions must be recreated.

Fixed

• Restore isolation: Failed restoration preserves visible local history and all identities and can never silently fall back to a new ACP session.
• Storage failure visibility: Missing or corrupt transcripts and blobs, plus checkpoint and commit failures, now remain visible in the session workspace.
