Damaged AACS units are holed, blanked and counted on every path instead
of stopping with E7013; failed batch partners fall back to side reads
and a wrong FMTS key is judged per key. ResolvedKeySet is the only AACS
decrypt door; a raw whole-disc reader never decrypts and refuses titles
with no stream folder (E6003) or a piece no held key opens (E7032).
Key-source contexts carry the op token and progress; DiscSession gains
open_with, scan_with and finish on the held handle. A consumer that
closes after a cancel keeps *.partial, and an artifact lock sidecar
guards each final output. Stop rules are enforced as lint tests.
A container-neutral fit plan, then mpg:// as an H.222.0 program-stream
sink on the PES IR and as a source through the DVD sector pipeline. PES
and AU placement, start-up hold caps and 20/24-bit LPCM timing follow
the spec; a clear MPEG-1/2 PS is never read as scrambled and CSS is
judged per pack. E9074 for an output with no video track.
ResolvedKeySet resolves keys up front, forensic keys included, and every
read surface decrypts through it. A keyless session never muxes
ciphertext; a single declared key keys only the pieces it opens; held
keys are tried before side reads. Resolve reports whether the disc's
VID would help, returns its trace on refusal, and never codes an
unreachable key service as Missing.
Waits are halt-aware on a stall timer; every CDB carries the op token;
prefetchers and pipeline joins honour Stop; flush is durable with
measured progress; the macOS shim open is cancellable. Also: CPI is
cleared on every decrypted unit, FMTS phase verification, the HD DVD
declared CPS count, AES work hoisted out of AACS hot paths, and the
last production unsafe removed.
