# @oshun/v9-cross-cutting

V9 cross-cutting concerns (V9_ARCHITECTURE.md §9; V9 backlog cross-cutting +
P3): determinism verification (same inputs+seed -> same hashes), cost discipline
(budget caps + no silent coverage truncation), accessibility
(captions/transcript/alt-text manifest + completeness), champion-challenger
statistical ramp gating, the anti-metric north-star guard (durable
understanding, NOT time-on-app), and LMS interop export
(SCORM/QTI/xAPI/Caliper/OneRoster). Composes the real engines; honest fail-loud
seams.
