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.

Claude Code v2.1.234

Notice acks now wait for the record to persist

Under the hood
Useful2 Signal3
Cross-Session Control

A cross-session notice is only marked delivered once its record actually saves, otherwise it retries.

What

Cross-session notices no longer ack on a best-effort flush. A new confirmed flush reports whether the delivery record actually landed, and if the upload was dropped the ack is skipped and the notice retried rather than being marked delivered.

Details
  • The uploader now counts batches dropped after a 4xx response and exposes that count, which is how the confirmed flush knows whether anything was lost.
  • The retry path is recorded as delivery_record_dropped_will_retry.

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