[SCITT] Re: Closing omission from the receiver's vantage — what a record must carry

[Nenad Vasic <[e-mail]>]

Walter, Henri, Todd, Joel, Pablo,

Items 1 and 2 of the opener's three are the half we run in production, in the
agent-authorization domain rather than payments. Offering the mapping here
because its resolution structure — rungs, wall, and the vantage that closes the
wall — lands exactly where this thread has already arrived for completeness.

Item 1. In our records the authorization is itself a signed record, not a field
the executor fills in: every action receipt carries a mandate_ref resolving to
the governing mandate — principal identity, agent identity, scope, sunset —
signed by the principal, and under delegation a hop-indexed leaf-to-root
lineage. "Which authorization governed this act" is answered by bytes the
executor cannot author alone, without asking the executor which authorization
it would like to be judged under.

Item 2 is where the receiver-vantage argument repeats one level up. The bound
in force at settlement is a function of the mandate's lifecycle — grant,
attenuation, revocation — and the executor benefits from presenting a stale,
broader version of it: the suppressed record here is the revocation. Same
asymmetry as the suppressed terminal seal, and the party who cannot be made to
un-know it is the principal, who signed the revocation. So I would add a row to
Joel's vantage table: issuer, independent observer, party owed the answer — and
the party that granted the authority. The receiver catches settlement omission
and cannot see a suppressed revocation; the principal catches the suppressed
revocation and cannot see settlement omission. Neither substitutes for the
other, which by this thread's own argument puts it in the substrate rather
than in any one draft.

The rungs carry over. Held bytes get you the first two: chain-verify the
lineage, recompute the authorization status rather than trust the executor's
flag — our verifier rule there is the one Pablo referenced, status as a closed
enum in which a verdict the verifier could not evaluate can never read as
authorized; post-revocation is an explicit case, not a missing row. Rung 3 is
where a revocation issued but never anchored is invisible to a receiver, and
Pablo's precedence property is exactly what is needed there: an anchor that
orders the revocation strictly against the settlement, not one that proves the
revocation existed at some point. So for the statement, anchoring_precedence
generalises: the event classes an external anchor has to order are Henri's
terminal seals, Pablo's settlements, and authorization-lifecycle heads.

On Joel's fourth item, the same answer Henri and Pablo gave: our status
verdicts carry no publisher-assigned version of the state they were computed
against. Because the lifecycle events are themselves signed records a verifier
can re-derive the as-of-T attribution, but the verdict object does not pin it,
and unattributable-by-default is the polite way of saying Joel is right. We
would add the field before claiming the item.

Structures and the offline verifier are in github.com/navigatorbuilds/elara-mesh
(docs/ELARA-VERIFY.md); the live feed at
navigatorbuilds.github.io/elara-mesh/receipts.html carries the lineage-bearing
records this message describes — including, as of today, one principal running
two agents under two mandates, which is item 1 made visible rather than
described. Our conformance vectors have been independently reproduced from the
spec text by two outside teams. If the statement takes profile contributions
for items 1–2 the way it cites Henri's completeness component, I would
contribute the authorization-resolution component from its published home,
under the same one-authority rule.
