**Safe active-run stopping** lets TypeScript transcript clients stop running or paused work at cooperative boundaries, retain completed generations and best score, and replay an idempotent durable terminal receipt after reconnect or restart.
**Durable interactive transcripts** add stable run, command, event, and sequence identity with bounded redacted retention plus exact reconnect backfill across server restarts.
**Ambient live serving** connects promoted per-role targets to live generation through a shared opt-in serving manifest, closing the resident trainer loop from evaluation to serving.
