Two claim classes report on one energy figure without changing the
receipt that seals it. `measurement` carries a bracket's values as
integers with each bracket's liveness facts, the build and the power
reader, and is accepted only against the receipt that carries its
figure. `operating-point` records the requested, committed and
delivered operating points and a prediction. The ratio, verdict and
residual are derived by every reader, never stated.
energy-measurement §6.2 gives the figure and the least declaration a
report's integers support as exact integer formulas; wai-rs
`energy_report` implements them with no floating-point arithmetic.
§3.1 defines a live power reader: a rail must advance in two
consecutive intervals, in at least five and in at least four of every
five, over at least 300 ms. A frozen or held rail is refused rather than
sealed under a hardware class. An unmetered `0` is never a figure of
zero joules.
A JWP object's figure, class and origin are bound into its Merkle leaf
(`\x02`), and a labelled group payload signs the total's class, its
coverage and the parent link. An object must sit at the position its
inclusion proof walks, and group signatures follow the strict Ed25519
rule claims use. `jwp_delivery` and `energy_figure` implement this in
wai-rs; joule-moq 0.2.0 builds and verifies both labelled forms.
New corpus `jwp-conformance/` with `jwp_verify.py`, more claim vectors
with the earlier ones pinned, and a CI job that runs claim_verify.py,
differential.py and jwp_verify.py. Legacy receipts keep their bytes.
External JWP implementations must adopt the `\x02` leaf and the
labelled group payload before verifying objects or groups that use
them.
