What

The helper that decides whether a run is a confined evaluation environment, used to gate a guess about where subagents write report files, now returns false outright when the confined-evaluation variable is set, on top of its earlier checks.

Evidence

!a.CLAUDE_CODE_EVAL_CONFINED && (X6() || qr(ee()) !== null)

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