Background (terra round, snapshot10g, gpt-6.1-terra/high): 7/7 pass, no product defects.
d1 two servers, TaskStop stopped only the first (8810 refused, 8811 200), both gone after exit. d2 exit 127/3 reported within ~1 s, tasks frames failed with codes. d3 CJK/emoji/ZWJ intact everywhere, no U+FFFD. d4 node --watch reload worked, process group gone after exit. d5 9th start refused with clear 8-task limit message; identical 10th refused by failure budget; all 10 stopped. d6 SIGINT mid-reply: synthetic 'Not run: the turn was stopped…' result, user marker saved, resume did not redo work, history valid for Responses API (14/14 function_call paired), no 400. d7 SIGKILL: server group gone in 1.1 s; saved session keeps synthetic result + marker; stale lock treated as stale; resume notice path exists (not launched).
ps/lsof by reviewer: nothing left on any scenario port or run folder.
Cosmetic (still): d2 exit code repeated 3x in the model-facing result (BashTool.ts:1088 error + :1081-1082 head line + toolRunner.ts:356-357 'Exit code: 3'); failureBudget quotedError de-duplicates only stop messages.
Latent assistantItems issue: not hit.
