Every input decrypts through one stage that detects its content, with
strict stale-CPI handling and partial units only at EOF. Damage no
longer ends a rip where usable content remains (E7031, UDF FID,
MPLS/CLPI truncation, whole-disc E7032). M2TS output declares tracks in
an HDMV PMT and paces PCR; network:// allows LAN and loopback and
is_blocked_ip is public; parity goldens pin today's outputs.
