The audio engine could already seek and nothing called it: no rpc, no
playback command, no binding. This wires it from every client.
The one real decision was where the arithmetic lives. A seek is relative
but the engine seeks to an absolute position, so either the client computes
a target from the last position update or it sends an offset and the engine
adds it to the live position. The offset wins on the ordinary case of
pressing the key twice: positions are broadcast on a 250 ms tick and then
cross the network, so three quick presses would all read the same stale
base and jump 15 s instead of 45. It also keeps the clamping policy in one
place instead of three clients, and matters more while paused, where no
position updates arrive at all.
So the wire carries sint32 delta_millis and the step is a client constant.
It also uncovered a live panic: seek_to did
`time.clamp(Duration::from_secs(1), duration)`, and `Ord::clamp` asserts
min <= max while `duration()` returns 0 for any source that reported no
length (HLS, some streams). That panicked the engine thread, killing audio.
Unreachable only because nothing called it; wiring seek made it reachable
from user input. It is now saturating arithmetic in a pure, exhaustively
tested function.
Boundaries: backwards saturates at 0 and never enters the previous track;
forwards stops 1 s short of the end so the track finishes through the
ordinary end-of-stream path (which advances the queue) instead of relying
on seek-to-exact-end, which decoders disagree about; an unknown duration
has no upper clamp. The engine emits Elapsed from the seek path itself,
because tick() skips a paused sink and a paused seek would otherwise show
the old position until playback resumed. An unseekable source (SoundCloud
HLS) warns server-side and changes nothing.
Ctrl-b/Ctrl-f join the existing control-chord family; plain f still toggles
the spectrum because lookup compares every modifier but SHIFT exactly. In
the browser Ctrl-f would open the find bar, but the keydown handler already
prevent_defaults any chord that resolves.
Seek is deliberately not tested through the playback loop: every test there
builds a real Player whose engine thread opens an audio device, so a test
that awaits a player reply passes or hangs depending on whether the machine
has working audio. The arithmetic is tested as a pure function, and the
rpc -> command mapping (the layer the paste bug lived in) in rpc.rs.
Verified: 20 audio-player tests (5 new: i64::MIN/MAX, zero duration,
sub-second tracks, composition, near-end saturation), 95 crabidy-server,
119 cbd-tui, 21 cbd-web, 58 server tests with --no-default-features,
workspace clippy clean under -D warnings, fmt clean, wasm bundle and book
build. Not exercised: an actual seek through an audio device.

Two bugs from the register work, both reported from actual use.
**Paste landed one row too far.** `QueueManager::insert_tracks` spliced at
`position + 1` — it inserted *after* the given index, while its own CLI help
says "insert tracks/subtrees at a position". So `p` (which sent cursor + 1)
landed two below the cursor and `P` (cursor) landed one below, exactly as
reported. The clients were already computing the right indices for an
insert-*at* API.
Fixed at the primitive rather than in the clients, because "after" cannot
express the front of the queue: the earliest reachable index was 1, so
pasting before the first row — and therefore undoing a delete of it — was
impossible. `insert_tracks` now inserts **at** `position`, pushing that row
down, with 0 the front and past-the-end an append. The two callers that
genuinely mean "after" pass `N + 1`: `ResolveKind::InsertAfter` (which keeps
its name and its streaming-chunk arithmetic) and `queue_tracks` (play-next,
`L`). All existing behaviour is preserved — the whole server suite passes
untouched — and three tests pin the new front/interior/play-next cases.
`queue insert <POS>` on the CLI shifts by one accordingly, which brings it
in line with what its help always claimed. Documented in the proto, the CLI
help, and the book.
**Queue marks were invisible.** The TUI rendered no mark indicator, so `s`
and visual mode had no feedback. Marked rows now carry the library's `*`
prefix and the same green bold; the playing row keeps `>` and its red, and a
row that is both shows `> * title`. The web client already rendered marks
(its `.marked .title` rule), but neither client showed visual mode outside
the TUI's pane title — both panes there now get a VISUAL badge in the
toolbar.

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.

The audio-devices command only listed. Give it an optional positional
argument: with none it lists as before; with a device name (or
case-insensitive fragment) it writes that into [audio] device in
crabidy-server.toml and then lists, so the same command both configures
and confirms (the chosen device is marked with *). If the fragment
matches no current output device it still writes but warns, mirroring
the server's startup fallback -- so a typo is caught here, not as silent
output.
Plumbing: AudioDevices carries an AudioDevicesArgs { device: Option }
on both `crabidy-server` and `cbd`; cli::audio_devices takes the option
and, when set, loads/updates/stores the settings via the existing
ServerSettings writer. README shows the set form.

The player always opened the system default output device. On a
Raspberry Pi that default is often HDMI, so playback ran but nothing
came out of the headphone jack or a USB/DAC -- "it plays but I hear no
sound".
Add an [audio] device option to crabidy-server.toml: a case-insensitive
substring of the output device name (a memorable fragment is enough).
The player engine opens the first matching device and falls back to the
system default with a warning if none matches. Absent config keeps the
system default, so existing setups are unchanged.
To discover the names, a new `crabidy-server audio-devices` subcommand
(also on `cbd`) lists the output devices and marks the one the current
config selects, using the same match the server applies at startup.
Plumbing: audio_player::output_device_names() enumerates via cpal;
Player::new(Option<String>) replaces the device-less construction
(Default = new(None)); Playback::new takes the device and serve() reads
it from settings. cpal's name() is deprecated in favor of description(),
but name() returns the ALSA-stable string users see in `aplay -l` and
match against, so it is kept behind a documented #[allow(deprecated)].
README documents the [audio] device option under the Pi/config section.

Every binary is now a clap-derive CLI; no subcommand keeps the current
default (run server / TUI / both).
- cbd-cli: run_remote executes library/queue/global against a running
server (mirrors RpcClient; direct Stop; connect+request timeouts;
concise errors; human-readable listings).
- crabidy-server: guard (hash + write [auth], stdin fallback, --no-config),
scan (walk + write .cbd-track.toml; --capture/--move via new
CrabidyStore::ingest_file), ServerSettings::store; replaces hash-password.
- cbd-tui: auth writes the client config; config load+override keeps the
first-run-defaults / flag-overrides-file behavior.
- cbd: union of server + client subcommands.
- build.rs in each binary generates shell completions + man pages
(OUT_DIR, and CBD_ASSET_DIR when set); devenv gen-cli-assets → dist/.
- README CLI section; tests for parse, config writers, scan/ingest, guard.
Deviations (plan/summary.md): ClapSerde kept; connection flags top-level
(not clap-global, to avoid colliding with auth --address); Box<dyn Error>
CLI reports per existing convention.

Stage 2 of the CLI dev-flow (api-design). cbd-cli holds the clap
Parser/Subcommand types for all three binaries (ServerCli/TuiCli/CbdCli,
library/queue/global, guard/scan/auth, Role, RemoteArgs), asset generation
(clap_complete + clap_mangen), and a feature-gated gRPC executor
(run_remote) whose per-command dispatch is stubbed for the implement stage.
Compiles with and without the client feature.
