AUDIT-WP-0009-T11 — register informed-decision, and answer GH-DEC-2026-014

informed-decision is the browser-facing approver surface; GH-DEC-2026-012
limit 3 makes its evidence copy the one that must reach audit-core
independently of the emitter, because there the actor being audited and the
evidence source are the same component.

Registration accepted on every proposed field — exact source,
["tenant:platform"], write true, read false, load-bearing, secret_policy
redact. Prepared and inert: the scope overlay applies only to a sender the
Secret already carries, asserted by test rather than by reading. Ingress ANDs
namespace and pod label in one peer, following approval-engine rather than
user-engine's older breadth.

Gate House asked whether the record shape can carry a source-held-content
declaration with a retrieval expectation, and asked for a straight answer
rather than a rule the storage cannot meet. Both halves, which must travel
together:

  It CAN carry the declaration. data is stored verbatim into details.data and
  hash-chained, so content_exists and custody need no schema change and become
  as tamper-evident as the commitment they accompany.

  It CANNOT detect non-production. audit-core performs no retrieval and its
  egress permits Postgres and DNS only. Detection happens at retrieval, by the
  reviewer; the stored declaration is what turns a blank into a failure
  attributable to the named custodian.

Residual stated rather than left to be found: a custodian that never held the
content can emit a false content_exists. audit-core validates the declaration's
shape, never its truth — the same class as omission at source, and not closed
by the chain, by attestation, or by T04/T06. A test asserts no egress to the
emitter exists, because that claim silently stops being true if one appears.

Cadence: reconciliation plus heartbeat is right for a mixed-volume source, with
both scoped per class rather than per source — a per-source heartbeat is
satisfied by the high-volume presentation stream and says nothing about a quiet
month of dispositions. Bound: a compromised emitter suppresses the event and
its own count together.

Also recorded: commitment-only satisfies non-alteration and never
reconstructability, in this repo's documents as in theirs; and tenant
provenance under GH-DEC-2026-013 lands in the registration record, not the
envelope, since audit-core checks a value the credential may write rather than
resolving an identity claim.

No secret was created and no production manifest applied.
