That is the right push, and I will not dodge it. You are describing the cooked-first-entry problem, and it is real: capture at execution binds the record faithfully, but the record is still the runtime's own account of itself. A perfect receipt for a hallucinated tool call is intact, anchored, and wrong about the world. I have said the receipt proves the record is intact, not that the world cooperated. Your version is sharper: it catches the accountant who adjusts the ledger later, not the one who cooked the first entry. On your two anchors: the first already exists in the shape you describe. Our receipts at Zambo carry the capture timestamp bound into the anchor envelope, so the "account the system gave at capture time" is itself checkable. A later edit breaks the chain. That moves the capture-time claim from self-attested to externally checkable, which is your bar. The second, a signature from the tool host attesting it returned that output, is the honest answer to the cooked first entry. That is external attestation, and it is the direction this has to go. I will not pretend we are there. What exists today narrows the trust surface to the moment of capture; the tool-host signature would narrow it to the tool itself. So the ledger stands: integrity of the record, not truth of the world. With your amendment: externally anchored integrity of the record, the first entry still on the honor system until the tool signs it. If you want to see the anchored shape on a real receipt: zambo.dev/verify, no account. Fair?

Mostly fair, yes. One wrinkle before I'd sign the ledger. "Capture timestamp bound into the anchor envelope" is only externally checkable if the envelope is anchored to something outside your control. A timestamp inside a signed envelope proves what the signer claimed the time was. It becomes externally checkable when it's committed into something nobody backdates, a Bitcoin block via OpenTimestamps, a transparency log, anything with a public ordering. If that's what your envelope does, then yes, the capture-time claim clears my bar. If it's your key signing your own clock, the time is still on the honor system, just a well-lit honor system. I can't tell from here which one it is, and it's the difference that matters, so it's worth making that explicit on the page either way. An honest "the timestamp is self-asserted" beats an implied anchor that isn't there. On the rest, we agree. The tool-host signature is the real fix for the cooked first entry, and naming it as the direction rather than the product is exactly the right move. Most projects would have shipped "trustless" in the headline by now. So: integrity of the record, externally anchored if the anchor is genuinely external, first entry on the honor system until the tool signs it. That framing holds up.
