Six inbound messages attended, three of them carrying real asks.

flex-auth FLEX-DEC-2026-004 answers WARDEN-WP-0034-T05's decision-lifetime
question: a decision lifetime shorter than the certificate TTL is meaningful,
but only as authority to ISSUE, never to USE an already-issued certificate.
The question had mistaken a decision lifetime for a credential lifetime. They
declined to move the §9.7.2 revocation residue to their side; that refusal is
right and the stance map is unchanged. T05 still waits on ops-mason and
railiance-infra.

WARDEN-WP-0039-T03 routed to flex-auth: is there an admitted contract for a
delegated credential read where caller and resource owner differ? Three
outcomes named as equally acceptable, including that there should be no such
contract and the interim proxy transport is itself the defect -- which would
shorten WP-0033 rather than block it. Two easy fixes ruled out in writing:
broadening the caller binding, and relabelling resource.system as ops-warden
so the binding matches. The second would make the audit trail assert we own
credentials we deliberately do not, by editing a field instead of making an
argument.

WARDEN-WP-0037: npm path routed to railiance-platform, catalog unchanged
pending their answer. secrets-engine refused to resolve it from a
coordination message and was right; asserting our own pointer is
authoritative because it is ours would route around that. The ask names a
location only, and flags that a `bao kv get` answer would be the 2026-07-16
disclosure vector on a risk: high lane.

@ -198,6 +198,36 @@ current access-engine implementation, received the decision-lifetime semantics
question (message `02c99a74`). No implementation or policy decision was assigned
to another owner by these messages.
**One of three answered, 2026-09-09.** `flex-auth` answered the decision-lifetime
question as `FLEX-DEC-2026-004` (flex-auth commit `6a6464f`), and answered it
rather than declining it: a decision lifetime shorter than the certificate TTL is
meaningful, but only as authority to **issue**, never as authority to **use** an
already-issued certificate. The action is `sign` and it completes at issuance, so
the decision is consumed once the certificate exists and no field in the decision
record reaches the artifact. 15m against a 48h `adm` certificate was never an
inconsistency to reconcile — the question mistook a decision lifetime for a
credential lifetime.
Two obligations land on this side and are accepted: no replay of an allow past
`expires_at`, and a fresh Check per sign. The second is where the value is, and it
is real rather than nominal because claims are not cached PDP-side (deadline 0 for
the claim class), so a revoked principal stops obtaining *new* certificates
immediately.
`pep-stance.yaml` §9.7.2 is unchanged and stays here: flex-auth explicitly declined
to move the residue to their side, on the ground that a PDP recalling an issued
credential would be "the same shape of lie as fail-open". Declining it was the
right call even though absorbing it would have made their record look tidier.
The TTL lever they named — capping requested TTL per actor class or zone, already a
policy input since `ttl_out_of_bounds` is denied before OpenBao is reached — is
noted and deliberately not requested. Shortening `adm` from 48h has an operator
cost, and issuance on this lane is too sparse (3 signature records across 79 days,
`pep-stance.yaml` `emission_cadence`) to price it from intuition.
T05 stays `wait` on the remaining two: `ops-mason` (no stance map published) and
`railiance-infra` (KRL distribution versus TTL expiry). Neither has replied.
