§1 now records five published routes to a reproducible stage, each from the paper section read. The explicit-parameter route keeps its entropy stage and lets the reconstruction drift: its body says so, and its periodic I-frames re-anchor the picture to one float decode (§3.2, Appendix B.8). Two integer routes join the quantised decoder: a float model run in a 16-bit integer mode, whose accumulators were observed not to overflow (§4.5), and an integer-trained codec (abstract only). One more line reaches no tier: float synchronised on a tested hardware class, whose streams decode only within the GPU groups its tests found (Table IV, §III-B). §7.1 cites the two records of float decode across devices beside WAI's record, and is not a comparison. syfai-input §5 and the September sweep's row of arXiv 2608.00483, G7 and F5 are corrected against the bodies read on 2026-11-03. research/catalogue-prior.md records a linear basis learned on openly licensed films of one studio, measured against AV1: its readings, procedure, decision rule and the time the rule was fixed. The rule refutes a linear or spectral catalogue basis and exact recurrence across titles for a studio's catalogue; a learned prior is not measured. tools/wai_catalogue_prior_verify.py recomputes every BD-rate and verdict from the readings and checks every figure the page quotes, in the conformance workflow.
