leak-guard bans the .invalid TLD (grouped with private .internal/.local/etc);
example.test is the RFC 6761 reserved test TLD — equally unreachable, not on
the ban list — so the leak-guard CI check passes.
libfreemkv deleted the aacs::boil veneer, so switch the resolve path to the
raw primitives: derive_media_key_from_{pk,dk}, derive_vuk, decrypt_unit_key
from aacs::derive, and the newtypes from aacs::types. Add a local uks_from_vuk
helper composing decrypt_unit_key. No behaviour change; fmt/clippy/test green
on Rust 1.86.
The online source dropped any MKB over 10 MiB while libfreemkv's reader
captures up to 64 MiB — an MKB in that band was silently un-forwardable
(no key, no surfaced cause). Match the cap and log when it is exceeded.
- KeydbSource implements KeySource::host_certs(), delegating to the
inherent host_certs() — surfaces the | HC | / | HC2 | certs already
parsed from keydb.cfg by libfreemkv's parser, so the OEM cert route
collects them across the keysource layer. No new parsing.
- OnlineSource::host_certs() is a no-op stub: returns empty with zero
network access (no client fetch, no server endpoint). Online host-cert
serving is deferred. TODO(owner) marker left in place.
Tests: trait host_certs returns the keydb HC row; empty when keydb
missing; online host_certs is an empty no-op without network.
OnlineSource::query() now includes the disc's volume_label (UDF/ISO volume id)
as a plain-text `title` field in the /decode POST, so the key service can build
a disc_hash → title catalog from real rips. Depends on libfreemkv 0.30.
Each source implements next_key (a cursor over its candidates) instead of
returning them all at once. The keydb hands its per-disc candidates out
UK-first (UK > VK > MK > DK) so a stale/wrong VUK never pre-empts a good UK in
the same entry; online and mapfile are one-shot. MultiSource composes sources
in the caller's chosen order and resolve_and_apply drives the
next_key -> decrypt_with loop, stopping at the first key that decrypts.
read_sample_units moves here so the CLI and autorip share one content sampler.
OnlineSource: the remote key-service client (moved out of autorip), posting the
disc's Unit_Key_RO.inf + MKB + Volume ID + encrypted content samples to the
service and returning the resolved unit key as a terminal Key::Unit candidate.
Kept out of libfreemkv so the library stays network-free. Source-internal
failures (unreachable / status / parse) are logged and surface as "no
candidate" so the next source is tried.
MapfileSource: reads a rip mapfile's persisted unit keys (the resume / deferred-
mux fast path) and offers them as a Key::Unit candidate. Keyed by mapfile path.
DiscInputs gained an app-populated `samples` field for sources that validate
against ciphertext server-side (OnlineSource); local sources ignore it.
