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 job state cache rewritten with a read-failure policy

Under the hood
Useful2 Signal1
Sessions

A broken job state file is rejected once instead of warning over and over.

What

The cache of per-job state files gained a mode where a failed read returns nothing rather than the last known state, and a state file that is oversized or not a regular file is rejected once instead of warning repeatedly.

Details
  • Modification-time keys, transient-error deduplication, prune reporting and sidecar-fallback logging moved from loose module-level maps into one object with named methods.
  • Callers pick the behaviour by asking for the null-on-failure mode.
Evidence

shouldReportTransient

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