Source Intelligence

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.

Provenance decides how a relayed event is spoken back into the conversation

Not switched on
Useful2 Signal5
Sessions Notable

Relayed messages are spoken back differently by source: verified humans as you, other agents as cross-session, world events dropped.

Sender provenance stored on delivered events, capped at 20 entries, decides delivery framing; reachable only under the poll-events gate.

What

Once accepted, sender provenance is stored on the delivered event, up to the first 20 entries, and controls how each entry re-enters the conversation. Text marked human-principal is emitted as a genuine user turn; peer-agent and anything else is wrapped in cross-session framing that does not read as your own instruction; world-event, or a missing or blank sender text, drops the delivery entirely. Reachable only under the same poll-events gate.

Details
  • The validation error message was widened to spell out the full set of accepted authority values.
  • None of these four authority values existed in the previous build.
Evidence

poll_event: sender_text dropped from provenance

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