What
All context_collapse_* telemetry events (apply, ctx_agent_spawn, recover_413, restore) were removed from the list of allowed telemetry events, and related fields such as claimedCollapse and the skipCollapseStatus logic in the memory/context summary builder were stripped out as well.
Why
This removes an existing feature, referred to internally as context collapse, along with its tracking, from Claude Code.
