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.

Claimed sender text must actually appear in the event

Under the hood
Useful2 Signal3
Sessions

A pushed message can no longer claim words it never actually delivered; mismatched sender text gets stripped.

What

If a pushed event says who sent it and quotes their text, the harness checks that the escaped form of that text really appears inside the event body. If it does not, the sender text is stripped from the recorded provenance and a warning is logged, so provenance cannot claim a sender string the delivered event never contained.

Details
  • Same poll-events gating as the rest of this path; the event itself is still delivered, only the unverifiable sender text is removed.
Evidence

poll_event: sender_text dropped from provenance \u2014 its escaped form is not embedded in the event element (derivation contract violated)

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