`opus` conflated two axes: decoding Ogg-Opus, and vendoring the C library
to do it. So the only way to avoid a cmake build of libopus was to give up
Opus playback -- the wrong trade for Nix, which already ships one.
The adapter crate draws the line already: symphonia-adapter-libopus own
`bundled` feature is what pulls opusic-sys/bundled and with it cmake. So
declare the dependency `default-features = false` and add
`opus-bundled = ["symphonia-adapter-libopus?/bundled"]`, forwarded up
through crabidy-server and cbd. It stays in every `default`, so a plain
cargo build still needs nothing installed; opting out is the packager act.
The weak `?/` is load-bearing -- a plain `/bundled` would enable the
optional dependency itself, and `opus-bundled` would quietly become a
second "do we decode Opus" flag.
The flake native build then drops cmake and takes libopus from nixpkgs;
`headlessFeatures` already omitted opus-bundled, so it opts out for free.
The cross build keeps the vendored copy: it links statically, and an
unbundled -lopus would need a static aarch64 libopus staged for the target
the way alsa-lib is.
That exposed an older bug. rustc stamps no RUNPATH, and the -L from
buildInputs arrives through NIX_LDFLAGS, which ld-wrapper does not mirror
into the binary -- so the package linked cleanly and then refused to start.
RUNPATH was empty, meaning libasound.so.2 had never resolved either: the
package always depended on the caller having it on LD_LIBRARY_PATH, which
this repo dev shell happens to set. autoPatchelfHook now fills the RUNPATH
from buildInputs (plus stdenv.cc.cc for libgcc_s, the compiler own
unwinding runtime, which no crate declares) and fails the build on anything
it cannot resolve. Verified by running each binary under `env -i`, and with
LD_BIND_NOW=1 so every opus symbol binds eagerly.
Also: devenv sets OPUS_LIB_DIR, without which the unbundled build dies as
"mold: fatal: library not found: opus"; check-features *builds* the two
libopus variants rather than clippy-ing them, since clippy links nothing and
cannot tell a resolvable -lopus from a missing one; and cbd was missing an
`rss` pass-through, so the bundle could not select that provider alone.
Requested alongside this: the spectrum shadows fall over 10 seconds instead
of 4. The config default and SpectrumStyle::default are two spellings of
one thing, so the config test now asserts the whole resolved style equals
SpectrumStyle::default() rather than field-by-field.

All on by default, so a plain build is unchanged (verified: the default
dependency set for crabidy-server is byte-identical to before). Tailor a
smaller binary with --no-default-features --features …
(architecture/build-features.md).
Compile-time features draw dependency boundaries; the existing
crabidy-server.toml providers list keeps doing per-mount runtime
toggling. The compile-time set bounds the runtime one: a provider built
out cannot be enabled from the config, and naming it earns one startup
warning rather than silence.
- crabidy-server: tidal · youtube · fyyd · abs · soundcloud · jamendo ·
fs · opus · spectrum · web-ui, plus the all-providers group.
- fs is local files *and* persistent state (D5): the /fs mount, the
content store behind /crabidy and /orphans, bookmarks/captures, queue
persistence, and scan. Without it Capture/SaveQueue answer
Unimplemented and scan says which feature is missing — never a panic.
- opus drops symphonia + symphonia-adapter-libopus, and with them the
bundled libopus C build (no more cmake requirement). It also decides
whether scan indexes .opus at all, so scan never indexes what this
build cannot play. An Ogg-Opus file in an opus-less build reports the
missing feature and is skipped like any undecodable file.
- spectrum drops realfft and the FFT task; clients just never receive a
frame. cbd-tui gains notifications (notify-rust, a D-Bus stack).
- crabidy-server/cbd features print the compiled set, and startup logs
it, so a tailored binary is self-describing.
Not gated, deliberately: [auth]/argon2 (a build ignoring configured
hashes would run open — fail-open security hole), and hls.rs /
spectrum_tap.rs / windowed_http.rs (no dependency of their own, so
gating them buys cfg noise and nothing else).
devenv gains check-features: the curated matrix (defaults, nothing, each
provider alone, each axis dropped, both worked examples, the client
crates) all clippy-clean under -D warnings.

rodio decodes through symphonia 0.5, which ships no Opus decoder, so raw
.opus sources (audiobookshelf files, and opus from any provider) failed
Decoder::build(). Add OpusSource, a rodio Source that demuxes Ogg with
symphonia own Ogg reader and decodes with libopus (via
symphonia-adapter-libopus, registered into an explicit codec registry), and
route to it by content-sniffing OggS+OpusHead in the player -- the abs stream
URL has no file extension, so the extension hint is not enough. The bundled
libopus builds with cmake/ninja (added to devenv).
Verified end-to-end with ffmpeg mono/stereo opus fixtures including seeking;
11 audio-player tests pass, clippy/fmt clean.

YouTube caps tokenless stream URLs at exactly their leading 1 MiB:
plain, open-ended, and oversized requests get 403, and fresh URLs
refuse offset starts, so playback died mid-first-minute. PO tokens
would lift the cap but the token-capable Innertube clients need
signature deciphering that is broken in rustypipe upstream (botguard
was built and tested — ineffective through the iOS client).
The player now streams every http(s) source through a windowed
SourceStream (bounded ~1 MiB ranges, 200-body fallback, eager
seek/reconnect so rejected windows fail typed instead of retrying
forever) and the capture downloader windows the same way. Stream URLs
come from a minimal yt-dlp sidecar again — metadata stays on the
pure-Rust rustypipe extractor — whose cipher-solved URLs stream whole
files at a throttled ~32 KB/s; a missing binary degrades to 1 MiB
streams with a warning. botguard_bin is wired through so streams flip
back to pure Rust when upstream deciphering recovers. Live-verified on
the exact track from the failure log.

- tonic 0.9 -> 0.14 (tonic-prost/tonic-prost-build split), prost 0.14
- ratatui 0.20 -> 0.30 (Frame no longer generic, Line instead of Spans),
crossterm 0.29
- rodio 0.17 -> 0.22: replace the custom symphonia decoder with rodio's
built-in decoder, seeking (try_seek) and position tracking (get_pos);
end-of-stream is now signalled via an EmptyCallback source with a
generation counter so a replaced track can never emit a stale EOS
- replace the vendored stream-download crate with the published
stream-download 0.24 (rustls), with a 30s open timeout
- reqwest 0.12->0.13 (rustls/webpki-roots/query features), base64 0.22
Engine API, rand 0.10, flume 0.12, thiserror 2, dirs 6, toml 1
- unify everything under [workspace.dependencies]; drop unused deps
(once_cell, serde_json in server; confique, secrecy in tidaldy)
- devenv: add protobuf (protoc) for prost-build
