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.

Anonymous. No account, no email.
What
A background cloud task now uses a fixed title of "Background task" and the branch name claude/background-task instead of asking the model to invent them, so it starts sooner.
Details
Chosen when the session being created is a background task, unless an existing outcome branch is being reused, in which case that branch is kept.
Not behind a flag; decided at session creation time.
Evidence
claude/background-task
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
