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.

Storage keys reject direct addressing of a job's timeline

Under the hood
Useful1 Signal2
Elsewhere

Internal storage now refuses attempts to address a background job's timeline file directly.

What

The key and scope validators now refuse job paths that point straight at a job's timeline stream, and say to use the dedicated key builder instead.

Evidence

is the job's timeline stream: address it as keys.jobTimeline(jobId)

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