- The C settlement kernel graded every receipt measured, from hardware, by
hardware_meter, whatever its meter; it now writes the grade and device the
meter states. Its host harness's figures are constants: projected, from a
simulation, by model_estimated (oer-receipts §2: an Estimator figure is
projected). The Zephyr skeleton states projected and no longer seals a
compute figure of 0. firmware_vectors.json is regenerated; both verifiers
pass it.
- wai-web: the world demo seals the page's estimate labelled Estimator and says
so on screen (label_page_figure, tested); the quantum demos seal the unmetered
marker instead of invented constants, and their getters say a 0 is unmetered.
- The quantum studio shows a figure with its class, coverage and uncertainty;
the quantum CLI prints the unmetered marker as unmetered (tested); the
metering tools head a bracket as a bracket and print the marker on stdout when
they seal it; a provenance total names the class it reads at (tested).
- energy-measurement §2.8 and §6 record which demos still seal an illustrative
figure the page passes in.
