Claude Code 2.1.318 (2026-11-04), rows that map onto yoyo open work:
Fixed -p/SDK reporting success when an API error cut off a reply (mirrors yoyo #1026: exit code on a cut reply).
NODE_EXTRA_CA_CERTS empty/non-PEM/damaged first cert: readable certs are now used, with a stderr warning (yoyo tls_preflight #1138 refuses with exit 1 only when zero certs load).
MCP: a call made before a tool is loaded now returns its input schema; stdio servers that exit on the version probe are no longer re-probed each start (yoyo still double-spawns for its collision pre-flight, #1134).
Background subagents move a shell command to the background after 3 minutes so the prompt cache does not expire.
