Scope: dated archive snapshot of the Netflix Sound Mix Specifications v1.6 (Netflix-branded deliveries); preferred over v1.4 for loudness. Netflix Sound Mix Specifications v1.6 (change log 2024-10-29; Internet Archive copy of 2026-08-09) applies to branded content only and keeps -27 LKFS +/-2 LU dialog-gated with peaks not above -2 dB true peak (BS.1770-1); the -24 LKFS program-gated fallback for under-15% dialogue now sits in a best-practices section stated to be not mandatory (BS.1770-3 or -4).

Curator qualifications: Archived page, not the live JS-rendered page; changes after 2026-08-09 unknown. Stem/bed requirements and the Atmos-bed vs stems ambiguity (F1 remainder, producer conflict) not fully re-read. Licensed content follows a different specification (v9.3), not read. Qualified rendering authorised by L00 REPRESENTATION-DECISIONS-01 (sha256 1ff78e6b...); not additional evidence; no execution or independent review claimed.

Limitations: Archive representation.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
