What files, metadata and HLS settings does Apple state for authoring and publishing Apple Immersive Video, and where do the stated bitrate tiers disagree?

Apple describes Apple Immersive Video as captured at 90 fps with more than 50 MP per eye, targeting 60 pixels per degree and up to 230 degrees field of view; WWDC25 session 403 recommends MV-HEVC 4320x4320 per eye at 90 fps in P3-D65-PQ for HLS, with the AIME VenueDescriptor and APAC audio referenced from the playlist. The session's spoken tiers (25-100 Mbps average, 50-150 Mbps peak) conflict with its own summary (25-150 Mbps average); the conflict is preserved. Curator qualifications: Correction to producer F2: Apple's transcript calls the 4320x4320/90 fps/P3-D65-PQ settings 'recommended', not requirements. Bitrate tier conflict unresolved; do not pick one. AIVU read/write, AIVUValidator and visionOS 26 VideoPlayerComponent statements (E2-E4, E7; session 296) not reinspected. Session page is live; transcript may change. Text only; no headset measurement, no encode. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary. Limitations: Vendor documentation; no independent measurement. [rights_conflict_record] Eligible as vendor format observation with recommended-not-required correction and preserved bitrate conflict. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
