weichenandCursor	b2dc9a7e0b	Pin agent-squad to the context-engineering native ci / vet-and-test (pull_request) Successful in 38s Details Why: The pin check requires backend's squad gitlink to match the Dev pin, and that squad commit carries the native context-engineering loop. Evidence: deps/agent-squad is 4d53450, whose agent-native gitlink is 6fd1d44. Impact: No backend behavior change beyond the shared native loop.

weichenandCursor	78ce78a7d3	Cap tool results by character and gate stale file writes Why: Byte truncation split UTF-8, subagent results could return unbounded text, and a write could overwrite a file that changed after it was read. Evidence: cutRunes keeps a two-character Chinese prefix; tool selection honors -name; checklist reminders go through the reminder bus. Impact: Tool output limits count characters. A subagent result over 32000 characters is stored as an artifact and the parent sees the path. fs_write_file rejects an existing file that was not read in this run.

Cap tool results by character and gate stale file writes

Why: Byte truncation split UTF-8, subagent results could return unbounded text, and a write could overwrite a file that changed after it was read.
Evidence: cutRunes keeps a two-character Chinese prefix; tool selection honors -name; checklist reminders go through the reminder bus.
Impact: Tool output limits count characters. A subagent result over 32000 characters is stored as an artifact and the parent sees the path. fs_write_file rejects an existing file that was not read in this run.
