about

nx_h264_bitwriter.nx -- MSB-first bit writer (hardware-rung primitive). The inverse of nx_h264_bits' reader: accumulate bits MSB-first into a byte buffer. Foundational for sovereign self-verification (encode->decode round trip = the oracle, no third-party reference) and for re-encode/transcode. Buffer must be zero-initialised (sys_mmap zeroes); we OR set-bits in. genealogy_id: msb_bitstream_writer lineage_id: bit_accumulate_msb_first license_tier: ORIGINAL
