DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Daemon config is written atomically

Under the hood
Useful2 Signal2
Elsewhere

The daemon config file is written atomically, so an interrupted write can't corrupt it.

What

The daemon configuration file is now written with an atomic publish rather than the default, so an interrupted write cannot leave it half-updated. Other writers in the codebase use in-place or follow-atomic modes.

Evidence

publishDiscipline: "atomic"

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