Transaction Science e39297fac6 wai.sink.models: which models a fleet's sinks may run, and what they ran 
A sink is a computer that runs named, pinned models: codec priors, DRED's weights, an exact
upscale's prior, enhancement and generator models. Nothing said which of them a fleet's sinks may
run, revoked one across a fleet, or rolled up what each class of device ran.

extensions/model-governance.md registers the record `wai.sink.models`, in the `models` profile
(core/profiles.json, CORE.md's table), outside the core. An operator signs a model policy
(`wai-model-policy`): classes of devices, enrolled by key or vouched for by an attestation key
(`wai-model-device`), and for each class the parameter sets it may run by the digest a pin names
(SPEC §3.1), per capability and role (decode, upscale, enhance, generate), with the least tier each
must run at; a span, a successor that takes its place from its own start, and the operator's key
log (jwp-receipts §7), whose `revoked_modules` revoke a set from the first revision that lists it:
the list SPEC §3.1 check 5 already reads at a sink. A device signs a run report (`wai-model-run`)
from what it already states: each decode's neural-dispatch report with the set it read (a sealed
set's opened digest too), and its sessions' exact-upscale presentation statements, whose sink-made
pictures name their prior or model. A verifier refuses a set outside the policy
(`model_not_in_policy`), a revoked set run at or after its revocation (`model_revoked`), a period
outside the policy's time in force (`policy_expired`, `policy_not_yet_valid`), a run below the
policy's tier (`model_tier_below_policy`) and a float path claiming decode-equivalence
(neural-dispatch's `dispatch_tier_refused`). The operator's roll-up (`wai-model-rollup`) states per
class the reports, the devices that reported and those enrolled that did not, and each set's
decodes by unit, frames and pixels, recomputed from the reports (`rollup_mismatch`).
neural-dispatch §5, exact-upscale §6.2 and fleet §1 point to it; no record they define changes.

The reference is the `model_policy` module of wai-rs (feature `model_policy`, in `full`);
`wai model verify` (catalogue `model.verify`) verifies a bundle (`*.wai-models.json`), and `wai
verify` reads a bundle and each record alone. The corpus is live-conformance/models/ (57 bundles:
3 accepted, 54 refused, every reason of §10 and every reused reason at least once), and
model_policy_verify.py is its second implementation, written from the text: it agrees on every
outcome, reason, place and statement, 14 of 14 mutated copies fail, and 51 of 51 weakened
verifiers are caught. vectors.json has one SHA-256 when generated on x86_64 and on arm64. 22
faults planted in the reference (a capability or role ignored, the revocation instant excluded, a
sealed set's inner identity ignored, the successor's start ignored, expiry unchecked, a float
path's claimed tier believed, silent devices and units miscounted, the signing domain, a period's
end included, the attestation's span, a statement counted twice, overlap, the roll-up's signer
and reports, a path's arithmetic, pictures' revocation, the tier compared the wrong way, the
successor chain, the key log ignored, an unnamed model admitted) each fail its tests. The
registry export, the operation catalogue and Studio's actions are regenerated by their tools.
