A dated record of one change, kept so the writing that cites it can be checked. Compiled from the sources listed below by the research run, not written for reading. The judgment lives in the signals and issues that cite it, below.

2026-10-13-claude-code-graders-and-unattended-runs-restricted-left-gaps-until-2-1-290-and-2-1-295-background-comm

Graders and unattended runs: --restricted left gaps until 2.1.290 and 2.1.295; background commands now time out. --restricted and an explicit --tools list did not strip built-in tools that register after launch until 2.1.295. Restricted sessions opened the cross-session messaging socket until 2.1.290; an @-mention could also read outside the working directories through a link changed mid-read until 2.1.290, and a parent’s --setting-sources restriction did not reach spawned teammates or background sessions until 2.1.281. Background commands gained a time limit in 2.1.285, 30 minutes by default and 2 hours at most, which 2.1.288 narrowed to unattended sessions; on stable it still applies to interactive sessions. --permission-prompts none is unchanged.

Channel: tagged-release (2.1.281 and 2.1.285 on stable; 2.1.288 onward latest only). Half: defect. Date: 2026-09-23 (2.1.281), 2026-09-29 (2.1.285), 2026-10-02 (2.1.288), 2026-10-05 (2.1.290), 2026-10-06 (2.1.292), 2026-10-08 (2.1.295).

Operator consequence: On stable 2.1.287 neither --restricted nor an explicit --tools list removes a built-in tool that registers after launch; pin graders to 2.1.295 or later and keep a sandbox or deny rules behind them. CI jobs that start long builds with run_in_background are killed at 30 minutes unless they set timeout (up to 2 hours), and interactive users on stable see the same until 2.1.288 reaches stable. Adapters that read the end of a -p run can expect background commands to finish before exit on latest.
