flake.nix first: its native package passed a bare --no-default-features,
which used to mean "everything but web-ui" and now means *no providers
at all*. It names its set explicitly
(all-providers,opus,spectrum,notifications); the aarch64 cross build
keeps the full defaults and its staged wasm bundle.
docs/src/build-features.md: the feature table with what each one costs to
lose, why fs takes /crabidy, /orphans, queue persistence and scan with
it, the opus/libopus build note, two worked examples, what is
deliberately not gated, and check-features. Linked from SUMMARY.md, and
config.md now says the providers list can only offer what the binary was
built with. README gains a short pointer.

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.
