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.
Conflicting uploads during directory sync fail immediately instead of burning retries.
What's wrong with this entry?
Anonymous. No account, no email.
What
Uploads that come back with HTTP 409 (conflict) now fail immediately instead of consuming the retry budget. Retries still happen for 429 and 5xx other than 501.
Details
409s are still counted separately for reporting.
The in-flight refresh promise is now cleared in a .finally, so a failed refresh no longer leaves the slot permanently occupied.
Evidence
if (b.status === 409) g.status409++;
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
