 # Changelog

-## [1.6.1]
+## [Unreleased]
+
+### Fixed
+
+- The online key service ignores `HTTP_PROXY`/`HTTPS_PROXY`/`ALL_PROXY`: with one set, every key lookup failed (the pinned resolver also answered the proxy's address, so the proxy request went to the key service).
+
+### Changed
+
+- `KeydbSource` hands out host certs best first, with no disc input: certs with no `Revoked in MKBv<N>` note in keydb order, then revoked ones by latest revocation. The inherent `host_certs()` and the `KeySource::host_certs` trait method both return this order; the trait ignores its `mkb` argument.
+
+### Deprecated
+
+- `KeyDb::host_certs(mkb)`: use `KeyDb::host_certs_ranked`.
+
+### Added
+
+- `KeyDb::host_certs_ranked`.
+- `check_keyserver_url` with `KeyserverUrlRejection`/`KeyserverUrlFault`: a typed Permanent vs Temporary verdict, so callers need not match `validate_keyserver_url`'s text.
+- `test-hooks` feature exposing `set_last_decode_reachability`, to test decode-verdict handling without a network.
+
+## [1.7.7] — 2026-09-26
+
+### Maintenance
+
+- Replace comment-overflow documentation with concise source contracts and README instructions; enforce the shared comment policy in CI.
+
+## [1.7.6] — 2026-09-26
+
+### Changed
+
+- Version aligned to 1.7.6 for the unified release. No functional changes to this crate; the release is driven by the freemkv 1.7.6 Linux desktop shell (GTK4 + libadwaita) and the rip-finished desktop notification (issue #56).
+
+## [1.7.5] — 2026-09-23
+
+### Changed
+
+- Version aligned to 1.7.5 for the unified release. No functional changes to this crate; the release is driven by freemkv-unlock mirroring the freemkv-firmware 0.9.0 ABI (the drive's `Ake` and `Bus` levers retired into a single `Encryption` lever).
+
+## [1.7.4] — 2026-09-21
+### Fixed
+
+- keydb lookups now report match state and entry shape, so a "no entry" result tells you whether the disc was truly absent or matched-but-underivable (no usable VID) (#46).
+- ureq 3.4.2 with a bounded, rolling-idle reply body, so a slow-but-progressing download is no longer killed by an absolute deadline.
+
+### Maintenance
+
+- CI moved to the central reusable workflows.
+
+## [1.7.3] — 2026-09-19
+
+### Changed
+
+- Unified release with freemkv 1.7.3 (`info --share` disc-structure capture for bug reports + the multi-angle UHD main-title fix in libfreemkv; see the libfreemkv/freemkv 1.7.3 notes). No functional changes to this crate.
+
+## [1.7.2] — UNRELEASED
+
+### Added
+
+- `OnlineSource` now records the reachability outcome of its actual `/decode` POST (an HTTP `Status(code)` for any answer, including 200/404/422/429/5xx, or `Transport` for a connect/timeout/DNS/TLS failure) in a per-thread slot, readable via the new `take_last_decode_reachability()` / `DecodeReachability`. This lets a caller (autorip) classify a no-key result from the REAL decode's outcome instead of firing a second, redundant probe against the POST-only endpoint. No behavioural change to key resolution itself.
+
+## [1.7.1] — UNRELEASED
+
+### Changed
+
+- Version aligned to 1.7.1 for the unified release (freemkv-unlock 1.7.1 LibreDrive unlock fix); no functional changes.
+
+## [1.7.0] — 2026-09-02
+
+### Changed
+
+- Version aligned to 1.7.0 for the unified release. Internal CI/lint hardening only (stable-clippy MSRV split, cargo-deny dependency-audit gate, audience-based comment-guard); no functional changes.
+
+## [1.6.14] — 2026-08-31
+
+### Changed
+
+- Version aligned to 1.6.14 for the unified release.
+
+## [1.6.13] — 2026-08-28
+
+### Changed
+
+- Version aligned to 1.6.13 for the unified release.
+
+## [1.6.12] — 2026-08-27
+
+### Changed
+
+- Version aligned to 1.6.12 for the unified release; no functional changes.
+
+## [1.6.11] — 2026-08-26
+
+### Changed
+
+- Version aligned to 1.6.11 for the unified release. No functional changes to
+  this crate; the release was driven by the libfreemkv main-feature selection
+  improvements and the autorip mux-quarantine fix (see the libfreemkv and
+  autorip 1.6.11 notes).
+
+### Added
+
+- Codecov coverage reporting and badge.
+- Substantially expanded unit-test coverage.
+
+## [1.6.10] — 2026-08-23
+
+### Changed
+
+- Version aligned to 1.6.10 for the unified release. No functional changes to
+  this crate; the release was driven by libfreemkv (TrueHD/MLP audio now resyncs
+  to the next major-sync access unit after a source transport-stream
+  discontinuity, instead of splicing post-gap audio mid-stream — fixing
+  decoder-choking seams on discs whose stream carries a continuity-counter gap;
+  see the libfreemkv 1.6.10 notes).
+
+## [1.6.9] — 2026-08-22
+
+### Changed
+
+- Version aligned to 1.6.9 for the unified release. No functional changes to
+  this crate; the release was driven by autorip (automatic per-episode TV
+  ripping — each episode named `S{NN}E{MM}`, with TMDB runtime-aligned episode
+  numbering across multi-disc seasons — a Manual Rename option, and a unified
+  per-disc staging state file — see the autorip 1.6.9 notes).
+
+## [1.6.8] — 2026-08-21
+
+### Changed
+
+- Version aligned to 1.6.8 for the unified release. No functional changes to
+  this crate; the release was driven by autorip (webhooks now fire per pipeline
+  stage — Rip / Mux / Move — with the Rip hook firing the moment the drive is
+  free again, plus a Ripper-tab activity-banner fix so it also shows during
+  moves — see the autorip 1.6.8 notes).
+
+## [1.6.7] — 2026-08-21
+
+### Changed
+
+- Version aligned to 1.6.7 for the unified release. No functional changes to
+  this crate; the release was driven by autorip (per-webhook event selection,
+  a progress bar per moved artifact, and move-queue / webhook-error fixes —
+  see the autorip 1.6.7 notes).
+
+## [1.6.6] — 2026-08-20
+
+### Changed
+
+- Version aligned to 1.6.6 for the unified release. No functional changes
+  to this crate; the release was driven by autorip (webhooks may now target
+  private/LAN addresses — see the autorip 1.6.6 notes).
+
+## [1.6.5] — 2026-08-20
+
+### Fixed
+
+- **A media, disc-ID, or VUK key at the end of a keydb row is no longer
+  lost to the comment beside it.** Many `keydb.cfg` rows end with a
+  `; MKBv…` note. When that note sat directly after the row's final
+  field and that field was the media key (`M`), disc ID (`I`), or VUK
+  (`V`) — rather than a unit key (`U`) — the note was read as part of the
+  value, the hex parse failed, and the key was silently dropped, so the
+  disc reported no key even though the file held one. The note is now
+  stripped from those three fields exactly as it already was from the
+  unit-key field (a hex value never contains `;`, so the split is safe).
+  A disc that stopped resolving for this reason resolves again.
+
+- **A misconfigured key service is no longer quieter than an outage.** A
+  mistyped port, an `http://` URL, or a key-service address the SSRF guard
+  refuses all mean the same thing: the service was never asked, so nothing is
+  known about the disc. They were reported as an empty result — the same value a
+  service returns when it genuinely holds no key — so a standing
+  misconfiguration surfaced to the operator as "no key for this disc" and never
+  self-corrected, while a transient DNS failure was correctly reported as a
+  failure. All three are now failures, logged at error level and separated in
+  the log text from an outage: one says fix the URL, the other says wait. A
+  later key source's real key still wins, so nothing that used to rip stops
+  ripping.
+- **A replaced `keydb.cfg` can no longer be missed.** The parsed keydb is cached
+  behind the file's identity, and that identity was size plus modification time
+  — which are byte-identical when a file is replaced within the same second by
+  one of the same length, the common shape of a daily refresh on a filesystem
+  that records whole seconds. The old, superseded keys were then served for the
+  rest of the process's life while every lookup reported success. The identity
+  now includes the file's inode, and a cache entry is not trusted until the file
+  has been unmodified long enough for its timestamp to be meaningful.
+- **A corrupt keydb keeps saying so.** The summary warning that counts rejected
+  and duplicated rows is produced while parsing, and the cache skips parsing —
+  so a damaged keydb warned once, at whatever moment it was first read, and was
+  then served in silence to every later disc. The summary is now re-emitted on
+  every lookup that serves that file. An intact keydb stays silent.
+- **A keydb's identity and its contents are read through one file handle.** The
+  cache used to stat the path and then separately open it, so a replacement
+  landing between the two stored one file's identity beside another file's keys.
+
+### Security
+
+- **`{:?}` on a keydb no longer spells out its keys.** `KeyDb` and
+  `DiscEntry` derived their `Debug`, so a single `{:?}` in a log line, a
+  tracing field, or a panic message wrote out every processing key and
+  every disc's media key, disc ID, VUK, and unit keys in full — on the
+  published file, all 184,860 discs' worth. Both are public API, so any
+  caller could trip it. Both types now format through a redacting `Debug`
+  that names each field without its bytes, matching the AACS types this
+  parser was split from, and a test fails if the plain derive ever returns.
+
+- **The host certificate's redaction is now pinned by a test.** `{:?}` on a
+  keydb host certificate does not print the AACS host private key, and never
+  did — but that depended entirely on libfreemkv's own redacting formatter,
+  with nothing in this crate to notice if it changed. The whole-database
+  formatter's test did not cover it. It does now, along with device keys.
+
+### Changed
+
+- **Breaking (API):** `KeyDb::disc_entries`' key and `DiscEntry::disc_hash` are
+  `Arc<str>` rather than `String` (a ~13 MB saving on the published keydb, which
+  is now held in memory). Code that requires an owned `String` from either needs
+  `.to_string()`. Unreleased in 1.6.4; recorded here because it shipped to git
+  consumers without a note.
+
+## [1.6.4] — 2026-08-15
+
+### Changed
+
+- **No functional change.** This crate ships alongside the rest of freemkv at a
+  matching version; its behaviour is untouched.
+
+## [1.6.3] — 2026-08-10
+
+### Changed
+
+- **The key service is reached over a newer HTTP client, with the same
+  protections.** Before contacting a key service this crate resolves the host,
+  rejects any private or link-local address, and then pins the connection to the
+  addresses it just checked, so a hostname cannot be re-pointed at an internal
+  machine in the moment between the check and the request. That behaviour is
+  unchanged; only the client underneath it moved.
+
+### Security
+
+- **The address pinning is now proven by a test rather than assumed.** The checks
+  that reject a bad address were well covered, but nothing verified that the
+  approved addresses were the ones actually connected to — and every existing
+  test still passed with that wiring removed entirely, because none of them
+  opened a connection. A connection made to an unreachable name can only
+  succeed if the pinned address is honoured, and that is now asserted. No
+  defect is being fixed here: the pinning was correct. It simply had no way of
+  telling anyone if it stopped being correct.

+
+Pluggable AACS key sources (keydb, online key service) for
+[libfreemkv](https://github.com/freemkv/libfreemkv). Each source looks a disc up
+and hands libfreemkv its terminal Unit Keys via `get_unit_keys`; the library
+does all derivation.
+
+## Development
+
+Build API documentation with `cargo doc --no-deps --open` for source construction,
+keydb paths and online-query contracts. Run `cargo test --tests` to validate
+parsing, caching and request guards. Tests use synthetic keys and local fixtures;
+never commit real key material or credentials.

-# leak-guard.sh — self-contained public-repo leak gate.
-#
-# This is the LAST line of defense in CI. It is intentionally self-contained:
-# public CI cannot reach the private tooling, so this script encodes ONLY the
-# generic net — internal infrastructure references, agent-context files, and
-# AI-attribution in commit messages. It deliberately contains NO project-
-# specific reverse-engineering vocabulary (those words would themselves be a
-# leak). The richer private scanner stays private.
-#
-# Fails (exit 1) if any of the following appear in the repo:
-#   1. a tracked CLAUDE.md or .claude/ path (agent context — never public),
-#   2. tracked file content matching the internal-infra net,
-#   3. a commit message (in the given range) with AI attribution.
-#
-# Usage:
-#   leak-guard.sh [<commit-range>]
-#     <commit-range>  optional git rev-list range to scan commit messages
-#                     (e.g. "abc..def"). If omitted, commit-message scan is
-#                     skipped (path + content checks always run).

-#   - private/internal/non-routable TLDs (.internal/.local/.lan/.corp/.invalid),
-#   - docker.internal.
-# The full org-specific net (literal hostnames, service names, repo paths,
-# vendor tooling, …) lives ONLY in the private scanner and never ships here.

-# Home-path net — GENERIC ONLY. Catches an absolute developer home path

-# path), so the pattern itself reveals nothing org- or person-specific. A real
-# leak (e.g. /Users/alice/Developer/x slipping into a public RELEASE.md) trips
-# this regardless of whose machine it came from. The username segment is a
