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.
