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.

Background Worker Respawn with Session Continuity

Background workers now track a resumeSessionId separately from sessionId, allowing a respawned worker to resume the correct session even if internal state has been updated. The respawn flag list is also persisted and restored on crash recovery, ensuring workers re-launch with the correct CLI flags.

Evidence

New resumeSessionId field (search for "resumeSessionId") and flag persistence (search for "respawnFlags")

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