The probe child now runs with the harness's credential-shaped variables scrubbed — the one rule every spawner uses, now defined in dsh-launch-environment and re-exported by dsh-subprocess — and its report is the one message echoing a per-run token the child removes from its environment, together with process.send, before importing anything. The failure text keeps the last 16 KiB of stderr instead of every byte, and the probe settles only on the child's close, so no pipe or channel outlives the call.

util/ — shared utilities
English | 中文
Summary
The util/ group gives capability packages shared mechanical primitives instead of duplicate implementations. It covers atomic writes, branded ids, deques, lossless JSON values, UUIDs, Harness-home paths, launch environments, outbound proxy policy, native commands, output retention, time-zone canonicalization, and timeout handling. Every root entry here is a library: it registers no product service or event, and the consuming capability retains the business semantics.
