v2026.5.17

Added

• Backend session materialization now creates stable degraded operations for transcript tool rows that lack canonical provider evidence, keeping the UI out of tool-link repair work
• Thinking blocks now support a shared default expand/collapse preference from the agent panel
• Question tool cards now let users submit a typed “Other” answer with Enter

Changed

• Historical session open, reconnect, resume, and state refresh paths now share stricter transcript-operation linking and replay-frontier behavior
• The composer toolbar now exposes mode selection beside model/config controls and keeps Autonomous as a right-side run control
• Review file lists now show clearer review status icons and diff pills

Fixed

• Copilot config files with managed // comments no longer break session startup
• Claude tool results that arrive without inline payloads can be backfilled from persisted provider history before falling back to an unresolved result
• Restored Claude local command messages are filtered from converted user-visible transcript history
• Optimistic user prompts stay visible until the matching canonical pending entry arrives
