What

Work that lived in the interactive prompt loop now belongs to the turn object, with no change to what happens on screen.

Details
  • Moved: loading-state reset, spinner tip selection, session signal tracking (bash tools, hosts, tools used), rate-limit auto-continue arm/cancel/prefill/retract, initial message submission with the resume partial-output hint, and queued input execution.
  • Many separate references, including file-read state, session env vars, tool state, memory selection, isolation latch, content replacement, tool and MCP computation, dialog requests and sandbox verdicts, were collapsed into one scope object on the host.
  • The telemetry involved already existed in the previous build.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
