v0.12.0

Changed

• memory_search and memory_search_global now declare openWorldHint=true, matching rerank auto-enable behavior that may lazy-load external models

Fixed

• memory_note_new now validates invalid task_id before writing a note, returning a structured JSON validation error without leaving an orphaned note file
• memory_evidence now rejects simultaneous paths and task_id arguments instead of silently preferring paths
• memory_state_show(as_json=False) now returns rendered markdown without duplicating structured sections in the same payload
