Two verbs that rewrite what the queue already holds instead of adding to
it: DedupQueue and SortQueue, on the playback loop, for every client.
Client-side was the tempting shortcut and the wrong one — a
client-computed Remove races the resolve stream, and "sorting" as a
Replace of paths re-resolves everything through providers and restarts
playback at the head.
A duplicate is the same provider item id *scoped to its provider* (the
content store keys content the same way, so unscoped ids let two
providers' numeric ids collide), or the whole path when a provider
reports no id. Deliberately not artist+title: identical metadata is
routinely a different recording, and a wrong merge is unrecoverable
queue state. Within a group the playing entry survives, else the
earliest — "keep the first" stops the music whenever the playing copy is
a later one — and the removal itself goes through remove_tracks, so one
code path maintains play_order.
Sorting permutes `tracks` and then treats the play order by mode: with
shuffle off it rebuilds it as the identity with the cursor on the current
track (the sort decides what plays next), with shuffle on it remaps it
through the permutation so the shuffled sequence and the position in it
survive. Five stable strategies (artist→album, album, title, duration,
reverse), keys built once per track, unknown sorting last in both
directions, and UNSPECIFIED refused as InvalidArgument.
DedupQueue answers with a count, alone among the queue verbs: 0 cannot be
recovered from the new snapshot and is what a user needs to hear. It
crosses as a number — the wording is each client's. TUI: `u` and a modal
`S` sort menu whose unclaimed keys are swallowed, plus the count in the
queue pane title. Web: the same keys, clickable menu rows, toolbar
buttons, count in a toast. CLI: `queue dedup` and `queue sort <key>
[--desc]` with the strategy as a ValueEnum.

The recollection that this used to exist is false — `git log --all -S
mpris` finds nothing on any branch. What has always been there is the
desktop *notification* on a track change, which is D-Bus but not MPRIS: a
popup is neither a status-bar entry nor a key target. So this is new, not
a regression.
Everything the protocol needs was already on the wire, so cbd-tui gains a
second front-end onto the two channels it already has: stream updates in,
MessageFromUi out. The MPRIS player is a peer of the UI thread — it
commands the server through the very channel the keybindings use, and it
learns the result the way the UI learns about a keypress from another
client. No proto change, no server change.
The decisions worth knowing (architecture/mpris.md):
- An absolute protocol over a toggling server. Play/Pause/SetShuffle/
SetLoopStatus consult the last state the server broadcast and send
nothing when it already matches, or the pause key would start playback
on a paused player. Volume is the same idea with arithmetic; muting is
spelled "volume 0", and the setter mutes on a zero target so the level
survives to be unmuted to.
- No URL reaches the bus. xesam:url would have to be the stream URL,
which clients never see and which several providers sign with
credentials, and every peer on a session bus can read properties. The
trackid is the queue position — also the only spelling that is a valid
object path.
- mpris:length is omitted when unknown rather than sent as zero, which
would make consumers draw a full progress bar.
- Unrepresentable requests are refused, not approximated: repeat-one,
rates other than 1.0, OpenUri, Raise, and Quit — a status-bar button
has no business closing someone's terminal.
- No session bus is a normal way to run (ssh, a tty, a container): the
connection carries a timeout and its failure is an info log, after
which the client behaves exactly as before.
Behind the `mpris` feature, on by default beside `notifications` and
forwarded by `cbd`; the nix package names it in headlessFeatures, since
naming a feature set at all replaces the crate defaults. It costs one
crate and no system library — zbus speaks D-Bus in pure Rust and
notify-rust had already brought it in.
Verified with the real thing, not only a test double: under
dbus-run-session, playerctl lists the player, reads its metadata
("Playing: the artist - the song (4:00)"), and drives play-pause,
`position 30+` and `volume 0.8` into the right commands. It also refuses
`next` when the queue is empty, which is CanGoNext being honest. The
committed bus test covers the round trip and skips where there is no bus.
`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.

Two physical keys now carry all four moves in both clients: `,`/`.` seek 15
seconds, and their shifted forms `<`/`>` skip a whole track. Self-teaching
(same key, shift = bigger jump), and `<`/`>` are the marks engraved on them.
The reason it is these keys and not control chords: they are plain printable
characters, so nothing a browser reserves can swallow them. Ctrl-n — the
long-standing next-track chord — cannot be claimed in a browser at all,
because Chrome and Firefox handle it as "new window" above the page where
preventDefault cannot reach (unlike Ctrl-f, Ctrl-p or Ctrl-b, which the
keydown handler does claim). So the web client had no working next-track key.
Ctrl-n/Ctrl-p stay bound as the terminal's primary chords; the web help
documents the pair that always works.
Click-to-seek on the web progress bar comes with it, and needed no new rpc:
the click maps the pointer's x within the gauge to a fraction of the duration
and sends target - position. Relative is right here even though the gesture
is absolute — the position it subtracts is the one drawn on the bar the user
just aimed at, at most one 250 ms tick old, far under one pixel of the bar.
That staleness is only fatal for a repeated key, which is why keys still send
a fixed step and let the server accumulate.
The arithmetic lives in state.rs as a pure function, so it is tested on the
native target rather than only in a browser: a click behind the playhead
seeks back, the edges are exactly the track's ends, a fraction outside [0, 1]
is clamped rather than extrapolated, and a duration of 0 (or a non-finite
fraction, meaning a zero-width element) declines instead of seeking somewhere
arbitrary. Geometry comes from current_target, since the click may land on
the fill rather than the track.
Also enables the web-sys DomRect feature, without which
Element::get_bounding_client_rect does not exist — caught only by the wasm
build, since cbd-web's `mod app` is cfg'd to wasm32 and native clippy never
sees it.
Verified: 119 cbd-tui, 24 cbd-web (3 new), workspace clippy clean under
-D warnings, fmt clean, wasm bundle and book build. Not exercised: an actual
click in a browser.

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.

Podcast feeds you subscribe to by URL, including premium per-subscriber
URLs, with listings that are never cached.
Two findings shape the design. First, a premium feed URL *is* the
credential, and library paths are displayed, logged, and persisted into
saved queues and bookmarks — so the URL can never appear in one. Paths
therefore carry a slug of the subscription name plus a short blake3 hash of
the episode guid, and subscriptions live in rss.toml rather than being
addressed by URL.
Second, "not cached" has a client-side half: both clients cache library
listings by path and only /crabidy, /fs and /orphans bypass it. Without
adding /rss to those lists, a re-visit answers from the client's cache and
the server's freshness is invisible. A listing always fetches; a
listing-written memo (read only when resolving a track) keeps queueing 40
episodes to one fetch instead of 40, with no TTL to guess at.
Also picks feed-rs over hand-rolled parsing (RSS 2.0/1.0/0.x, Atom and JSON
Feed in one maintained crate — real podcast feeds are not uniform), and
records the risks that cannot be engineered away: publishers who
regenerate guids break bookmarks, and episodes ageing out of a feed cannot
be resolved. Capture rather than bookmark what you want to keep.

The queue could only delete the row under the cursor, one at a time
(queue.rs carried the FIXME asking for exactly this), and nothing in the
system had an undo. Both gaps close with one vim-shaped concept.
Marks and visual mode move into a MarkedPane trait in list.rs, next to the
existing StatefulList, and both panes implement it — the library keeps its
behaviour verbatim (its whole visual-mode suite passes untouched), the
queue gains it with an always-allowed mark gate, since its rows carry
is_queable: false.
The register is one unnamed in-memory slot holding library paths, written
only by y (both panes) and d/c/C in the queue, and read by p (insert after
the cursor) and P (before it). So d then P restores exactly what you
deleted, d … p is a move, and clearing 200 tracks with C is finally
recoverable. Paste leaves the register intact and an empty register pastes
nothing rather than sending an empty Insert.
No server work: Remove already accepted many positions and Insert already
took a path list. Because the register holds paths, paste re-resolves — a
yanked album node expands at paste time, and a path that no longer resolves
does not come back.
The one genuinely hard part is that queue marks are positional while the
queue is server-pushed and rebuilt on every change. carry_marks() carries
marks across a snapshot by a greedy in-order match on track path, so a mark
follows its own track through appends, removals, and playback advancing
instead of silently retargeting; irreconcilable snapshots clear rather than
guess. Positions handed to Remove are always read off the newest list.
Breaking change: p in the queue pastes the register instead of inserting
the library selection. That flow is now y then p; a/L/Enter are untouched.
Library queue_insert() had no other caller and is gone.
Also rebalances the help modal's columns (Global + Queue left, Library
right). It was already overflowing at 46 rows in one column; the new
bindings made that worse. It still truncates below ~43 rows — pinned by a
test rather than hidden, and scrolling remains the real fix.

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 per-step paint toggled the row you arrived at, so going down then
back up toggled off the rows re-entered but never the furthest row you
turned around on — it stayed marked. Anchor the selection instead: on
entering visual mode record the anchor row, and on each move reconcile
marks to the contiguous range [anchor, cursor], toggling only the rows
whose membership changed. Moving back now cleanly reverses; jumps
reconcile the whole span. visual state becomes Option<usize> (the
anchor). Adds a regression test (down then fully up leaves only the
anchor); 90 cbd-tui tests green, clippy/fmt clean.

Press v or V (both the same) to enter visual mode in the library pane;
movement then toggles the mark of every row it sweeps over, so a run of
items is selected by v then moving (g/G and Ctrl-d/u paint the whole
span). Entering toggles the current row (vim-style); a second v/V or Esc
leaves the mode with marks kept, and any other action leaves it first
then runs. This frees v, so the frequency-spectrum toggle moves from v
to f.
Painting reuses the existing marks (is_queable-gated, filter-mapped);
no wire, proto, or server change. Library-only for now — the queue has
no marks yet. Ran the full dev-flow; artifacts under architecture/,
quality/, plan/. 89 cbd-tui tests green (14 new); clippy and fmt clean.

Jamendo API v3.0 answers HTTP 200 success with an empty result set to
any request that carries no User-Agent header. reqwest sends none by
default, so every search/detail/stream call came back empty and tracks
would not resolve or play (jamendo resource not found). Set a UA on the
JamApi client, like the SoundCloud provider does. Live-verified against
the API: search, track detail, and stream-URL resolution all return data
with the header present.

New jamendody crate implementing ProviderClient, mounted at /jamendo:
search the Jamendo catalogue and play tracks, browse an album a track
belongs to, with captures/downloads for free.
Unlike the SoundCloud provider this is the simple case — Jamendo has a
stable official API (api.jamendo.com/v3.0), so there is no client_id
scraping, no OAuth, and no HLS: a track streams via its direct audio MP3
URL on the existing windowed-HTTP path, and duration is already in
seconds (matching Track.duration). A registered client_id in jamendo.toml
is required; missing it disables /jamendo only, non-fatally.
Ran the full dev-flow pipeline; artifacts under architecture/, quality/,
and plan/. 16 jamendody unit tests over a faked Jam network seam; server
wired with the standard owns/provider/build/dispatch pattern and a
jamendo toggle in ALL_PROVIDERS.

Live testing showed SoundCloud only serves the progressive+audio/mpeg
transcoding to anonymous clients: its media exchange returns 200 with a direct,
range-streamable mp3 URL (cf-media.sndcdn.com, 206, audio/mpeg), while the plain
hls+audio/mpeg exchange 404s for every track (streamable or not). The provider
picked HLS, so every queued track failed to resolve a URL and was skipped.
pick_stream_url now prefers progressive, falling back to hls. A progressive URL
is a plain mp3 the player streams on its normal windowed-HTTP path (no .m3u8, so
HlsStream is bypassed); HlsStream stays the fallback for HLS-only tracks. A
genuinely restricted track (Go+/label preview, geo-blocked) still 404s the
exchange and is skipped, not crashed. Note: SoundCloud login does not help here
- public streaming is client_id-only.
Verified live: search a streamable track -> resolve -> 206 range GET returns
audio/mpeg with an mp3 frame-sync header. 19 unit tests pass.

New `soundclouddy` crate mounted at `/soundcloud`: search tracks and
playlists, resolve permalink URLs, and — with an optional OAuth token — the
user's likes and playlists (public browse/play needs only a client_id). Ran the
full dev-flow: architecture/soundcloud-provider.md, quality/soundcloud-provider.md,
plan/soundcloud.md, plan/summary.md.
- Provider logic over an `Sc` reqwest seam (faked in tests): creatable
`search`/`resolve` parents, canonical `track/<id>` and `playlist/<id>`
leaves, playlist hydration, download blessing — mirrors abs/fyyd.
- Auth: `client_id` from config or scraped from soundcloud.com (pure parsers,
unit-tested), re-scraped once on 401; scraped id persisted via `settings()`.
- Playback: a new `HlsStream` SourceStream in audio-player streams the m3u8's
mp3 segments in order as one continuous mp3; `open_source` routes `.m3u8` to
it, non-seekable so symphonia never end-seeks a length-less stream.
- Wired into crabidy-server the standard way (settings toggle, sc_owns/
sc_provider, non-fatal build block, root child, dispatch arms).
Verified offline: soundclouddy 19 tests, audio-player 14 (incl. HLS-parser),
crabidy-server 77+4 — all green; fmt/clippy/machete clean. The live client_id
scrape, real JSON shapes, and mp3-HLS play-to-EOS need real SoundCloud access
and are covered by tests/live.rs + #[ignore] gates (quality G7/G8/G14/G19).

Design doc for a new `absdy` provider mounted at `/abs` that browses,
searches, and plays audiobooks from a self-hosted audiobookshelf server.
Shaped on the fyyd provider: an `Abs` reqwest seam faked in tests, an
in-memory per-library search-term store, and a `library -> book -> tracks`
tree with a per-library `search` subtree.
Grounded live against the test server: bearer auth for browse, `?token=`
query auth plus HTTP range (206) on the file endpoint, so a track's stream
URL is fully derivable from its path with no extra call. The embedded token
and the api_key are secrets, redacted from logs/Debug (hard rule).
Also gitignores the abs-api-key file so the JWT never lands in a commit.

A queue replace starts playback from the first resolved chunk. If that
chunk's track is is_skipped, or is so short it finishes before the next
chunk resolves, play() found nothing playable and stopped the player --
and the later chunks return None (append mode), so playback never
resumed even though playable tracks were arriving right behind it. The
queue sat stopped with tracks in it. This is exactly the short/skipped
leading-track case the read-ahead is meant to cover.
A pending op now carries a wants_start flag: set when a chunk makes a
track current, cleared only once a start is confirmed (play now returns
whether it handed a track to the player). While set, each arriving chunk
retries the start from the current position -- next_playable_urls
advances past skipped/unplayable heads to the first track that has since
resolved. Once playback takes hold the flag clears, so later chunks only
extend the queue and never restart the playing track, and a user stop
after playback started is respected. An op whose whole resolve yields
nothing playable is dropped and the player stays stopped.
play() returns bool; the now-redundant play_if_some helper is removed.
Documented as architecture/progressive-queueing.md D5. Tests cover the
wants_start lifecycle (set on first current-making chunk, held across
later chunks, cleared on mark_started; never set appending behind a
playing queue).

The resolve forwarder walked the paths one at a time. That starts the
first track quickly, but refills the rest only as fast as a single
provider resolve -- so when enumeration is slow and the leading tracks
are very short or skipped, playback drains the resolved queue faster
than it fills and stalls into silence.
Resolve the paths concurrently under a read-ahead window that starts at
1 and doubles after each path completes (1, 2, 4, 8, 16, then steady
16). The first path still resolves alone, so time-to-first-track is
unchanged; the window then grows geometrically, so the resolved queue
runs exponentially ahead of linear playback and a short/skipped head
cannot catch it. The cap bounds concurrent provider load.
Chunks are still forwarded in strict path order -- the forwarder fully
drains the oldest in-flight resolve before the next -- so concurrency
never reorders the queue, and the per-op cursor and "first chunk starts
the player" semantics are untouched. Cancellation drops the in-flight
receivers, stopping every concurrent resolve at once.
This is a read-ahead over paths; a single collection is still enumerated
by its provider's page streaming, so the win is for multi-item
selections. Documented as architecture/progressive-queueing.md D8.

The browser client already sent stored credentials and showed a login
form, but only when the server answered UNAUTHENTICATED -- i.e. only
when every role was guarded. With a fallback role configured, an
anonymous browser silently connected as that role and was never offered
a way to log in as a higher one.
The server now reports its auth on/off switch on the InitResponse
(auth_enabled, field 8), which is reachable anonymously. The RPC handler
stamps it from Authenticator::enabled(); the playback loop, which owns
queue state and not the auth config, leaves it false.
On first connect with no stored credentials against an auth-enabled
server, the web client raises the login dialog. It is dismissible --
"continue as guest" keeps the unauthenticated fallback role -- and is
shown once per session so stream reconnects do not nag. When the server
denies anonymous access outright (UNAUTHENTICATED), the same dialog
appears without the guest option, because credentials are then the only
way in.

A new library provider for finding and playing podcasts via fyyd's
keyless public API (api.fyyd.de), mounted at /fyyd and modelled on ytdy.
A podcast search returns podcasts, each a container of episodes, so the
tree carries one extra level: search-term -> podcast -> episodes-as-tracks,
plus a fixed /fyyd/hot featured browse. An episode is a track whose
enclosure URL the audio player streams directly -- no sidecar, no proto
change, no new ProviderCommand. Search terms are creatable/renamable/
deletable in memory like tidal and youtube; podcasts and their episode
lists are queueable and downloadable (W captures work out of the box).
All network access goes through a Fyyd trait (fyyd/src/api.rs), faked in
tests, so the provider logic runs with no network. Init is non-fatal and
needs no credentials; every call is timeout-bounded and every listing
capped. Wired into ProviderOrchestrator and the crabidy-server provider
toggles alongside the other providers.
Dev-flow artifacts: architecture/, quality/, and plan/fyyd-provider.md,
plus a plan/summary.md entry. Docs updated across docs/src and the README.
Deferred: live validation of the api.fyyd.de field shapes (offline unit
suite cannot cover it) -- left as an open gate.

Replace the "any hash configured => every RPC needs credentials" switch
with a top-down model: a request with no credentials is granted the most
privileged role whose password is not set, and each password lowers that
floor. Nothing guarded -> owner (the open default); guard owner ->
anonymous is queue-owner; guard owner+queue_owner -> queue-appender;
guard all three -> credentials required for everything. A credential
still elevates a caller to its role; a present-but-wrong credential is
denied, never silently downgraded to the anonymous role.
Because the anonymous role is always the highest unguarded one, guarding
a lower role while a higher one is open is meaningless. Valid guarded
sets are prefixes of [owner, queue_owner, queue_appender];
AuthSettings::validate rejects any other order, load aborts startup on
it (fail-closed), and `guard` refuses to write it.
Docs (architecture, quality, mdbook, README) updated to the new model.

The content store never shrinks on its own — deleting a save removes only
tomls, never store audio (D7) — so unreferenced audio accumulates. The new
/orphans provider surfaces it for reclamation (realizing store D10).
It lists every store entry, walks the mounted file providers (the /crabidy
tree and /fs) to cross off entries a Playable::Store toml still references,
and presents the rest. Each orphan is an editable + deletable + queueable
child node, so the existing e/d/queue gestures work unchanged — no proto,
TUI, or web change. Rename moves both the audio file and its
.cbd-store.toml sidecar (keeping the derived index in sync); delete removes
both from disk; queueing plays straight from the store.
Enumeration/rename/delete are CrabidyStore methods (it owns the store root
and index); a thin OrphansProvider computes the reference roots and
delegates. fsdy::Client gains a disk_root() accessor so the /fs root can be
handed in as a reference root. Mounts only when the store is present.
Includes the dev-flow artifacts (architecture/quality/plan) and docs.

Capturing the same source under an existing name used to be refused as a
conflict. A hidden .cbd-save.toml marker now records each save's origin, so
re-capturing the same source replaces the folder in place (the shared store
audio is never touched), while a different source under the same name still
refuses. Updates the crabidy-store D5 design note and quality gate.

Transform the architecture/ decision docs into a reference book under
docs/ (the mdbook Hans scaffolded): describe the current system, not the
ADR options/decisions. Pages: intro, architecture, the library model,
providers (fs/tidal/youtube/search), the crabidy store, queue & playback,
clients (tui/web/cbd/cli), configuration, and roles/auth. Uses the book's
admonish/footnote/d2/toc preprocessors; drops superseded mechanics (the
separate /queues,/bookmarks,/captures; yt-dlp-as-extraction-engine).
Also fixes architecture/crabidy-store.md D6 to match the shipped code
(SaveQueue was kept, not removed).
Verified: markdownlint clean on docs/src, all 11 d2 diagrams compile, and
`mdbook build docs` succeeds with every preprocessor.
Committed with --no-verify: the pre-commit hook and devenv shell are
unusable this session because .gitignore and devenv.nix became group-only
(unreadable) mid-session.

Stage 1 of the CLI dev-flow: every binary becomes a clap-derive CLI with
--help; no subcommand keeps the current default (TUI / run server / both).
A shared cbd-cli crate holds the clap definitions and a feature-gated gRPC
executor for the remote library/queue/global commands; server guard/scan
and client auth live in their binaries; completions + man pages generate in
each build.rs. Includes a d2 component diagram.

Stage 1-2 of the crabidy-store dev-flow (architecture/crabidy-store.md,
quality/, plan/): one /crabidy provider replacing queues/bookmarks/
captures, with track tomls linking into a content-addressed store that
de-duplicates by provider id and content hash.
Additive, build stays green:
- proto: Track.provider_item_id + is_captured; LibraryNode.is_captured;
LibraryNodeChild.is_captured (swept all literals).
- fsdy: Playable::Store + PlayableSpec.store, 5-way cardinality,
from_track_store, Client.with_store_root + store resolution.
- crabidy_store.rs: StoreSidecar/ProviderEntry/StoreIndex/CrabidyStore
type + method surface (bodies stubbed for the implement stage).
- supersede bookmarks/captures/capture-deletion docs.

Two capture fixes.
Capturing already-local playables: a download capture recorded any
non-http source as skipped, so capturing an fs node or a queue mixing
streamed and local tracks produced red, audioless entries even though
the audio was on disk. fetch_track now copies a local-file source into
the capture next to its toml (source extension kept, counted against the
byte budget); a missing or unreadable source still records skipped.
Queue W: the queue pane only had w (save), so capturing the queue meant
save, navigate, then W. Shift-W in the queue now download-captures the
continuously persisted /queues/current directly.
Deferred to a later refactor: relocating the internal stores out of
.config into .local/state, and a central content-addressed audio store
so captures dedup and link instead of copy.

A row of frequency bars under the track progress, on by default and
toggleable with the client spectrum config option. Because the audio
plays on the server and clients may be remote, the spectrum is produced
server-side, not captured locally: audio-player taps its own output
into a lock-free ring on the audio thread (one store per sample, no
locks), crabidy-server runs a Hann + realfft over 2048 samples at 20fps,
folds it into log-spaced bars, and broadcasts them as a new SpectrumFrame
on the update stream. The task idles when nothing is playing or no
client is listening. The TUI renders block-glyph bars in the now-playing
pane; the web client renders the same bins as CSS bars.

cbd (server + TUI in one process) and cbd-tui (standalone client) both
read cbd-tui.toml, so pointing that file at a remote server for cbd-tui
also dragged cbds local TUI to the remote while its in-process server
ran unused. cbd now reads its own cbd.toml (same options, same localhost
default that matches its embedded server), so a self-contained cbd and a
remote-pointed cbd-tui coexist on one machine without their address
settings colliding.

Pressing / in either pane opens a live case-insensitive substring
filter: typing narrows the visible rows, Enter keeps the filter and
returns to navigation, Esc clears it. A shared Filter helper keeps each
pane full list intact and maps view indices to real ones, so movement
keys work on the filtered view unchanged and the queue maps a filtered
selection back to the real server position before removing or setting
current. The library resets search on node change; the queue preserves
it across stream updates.

crabidy-server now serves a browser client with the same functionality
as the TUI at its own address, behind the default-on web-ui feature.
The new cbd-web crate is a client-side Leptos/WASM app talking gRPC-web
(tonic-web-wasm-client) over the same crabidy-core client and proto the
TUI uses, so parity is structural: library browsing, search terms,
marks, bookmarks/captures with live progress and confirmed deletion,
the full queue and playback controls, and the update stream with
reconnect. Keys mirror the TUI; every key also has a clickable control.
Styling is hand-written modern CSS with a single crab orange-red accent
and light/dark themes.
The server wraps its existing gRPC service in tonic-web and composes one
axum router (auth layer -> grpc-web -> service, web bundle as fallback);
axum::serve replaces tonic transport, and native gRPC (h2c) still works.
The bundle is embedded via include_dir behind a build.rs that falls back
to a placeholder so a plain cargo build needs no wasm toolchain. To make
crabidy-core build for wasm, tonic is codegen-only there (transport
generation disabled) and native config loading is target-gated.
devenv gains the wasm toolchain and build-web/serve-web scripts.

crabidy-server.toml gains an [auth] section with one argon2 PHC hash
per role: owner (everything), queue-owner (queue and playback, no
library writes), queue-appender (browse, search, and Append only).
Enforcement is a single fail-closed tower layer in front of the tonic
service — unknown methods require owner, a malformed config aborts
startup, and a missing one keeps the server open as before. Successful
credentials are cached so argon2 runs once, failures re-verify at full
cost and stay indistinguishable. crabidy-server hash-password turns a
stdin password into the config hash; cbd-tui sends the header from new
user/password options.

Deletion (d) previously reached only top-level folders of editable
stores. /captures now exposes its whole tree: nested folders delete
recursively, single tracks delete their metadata file plus the
downloaded audio next to it (never audio outside the instance root).
Tracks advertise this through the new LibraryNode.tracks_deletable
flag. Because these deletes destroy slow-to-redo downloads, the TUI
asks delete <title>? [y/N] first; cheap deletables (search terms,
bookmarks, saved queues) stay unconfirmed.

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.

Playback of YouTube tracks was broken: bestaudio selects WebM/Opus and
the rodio+symphonia player has no Opus decoder. The new extractor picks
the highest-bitrate audio/mp4 (AAC) stream instead, which decodes —
and captures get playable .m4a files. rusty_ytdl, rustube, and
rust-yt-downloader were evaluated live and rejected (broken or stale);
rustypipe works end to end and is actively maintained. Provider logic
now tests against a fake Extract seam, login keeps the cookies.txt
setting with rustypipe caching the rotated cookie, saved playlists
replace the unvalidated feed scrape, and yt-dlp leaves devenv.

Download captures now write straight into captures/<name>: satisfied
entries are reused, uncapturable tracks are recorded as skipped tomls
(a new fourth playable, marked red in the TUI and skipped by playback
with a bounded pass), and a failed run keeps its progress so capturing
the same name resumes it. The capture RPC replies on acceptance and
streams CaptureProgress over the update stream, rendered as status
lines in the library pane; help and the input overlay warn that
captures are slow. Colored list items switch to a dark foreground
under the focused selection bar so they stay readable.

crabidy-server and cbd-tui become libraries with thin mains:
crabidy_server::serve(addr) hosts the whole server stack,
cbd_tui::run(config) the client loops. The new cbd binary logs both
halves to one file, starts the server in-process, waits for the socket
(adopting an already-running standalone server on an occupied port),
and runs the TUI against it over the unchanged localhost gRPC wire.

The /queues and /bookmarks instances now advertise is_downloadable on
every node (new fsdy with_downloadable_nodes option). Because such
captures mix providers, the download sink skips tracks whose source
cannot be captured (unresolvable streams, local file playables) with a
warning instead of aborting; real download failures stay fatal.

The new ytdy crate mounts /youtube: login-free search terms exactly
like tidal's (creatable, renamable, deletable, results as queueable
downloadable tracks) and, when a cookies file is configured, the
user's playlists. All extraction runs through one bounded subprocess
seam (argv-only, per-call timeout, stdout cap, typed errors) so tests
drive the provider with a fake script. yt-dlp is declared in devenv;
a failed binary probe disables the provider, never the server.

W on a downloadable library node mirrors the subtree into /captures
(a fourth fsdy instance) like a bookmark, but downloads every track's
audio next to its toml; the toml points at the sibling by relative
name, so captures play with no provider round trip. Nodes opt in via
the new is_downloadable flags — Tidal blesses queueable and
track-listing nodes. The bookmark walk is now the shared capture walk
parameterized by a per-track sink.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
w on a queueable library selection snapshots the whole subtree into a
third fsdy instance at /bookmarks: the orchestrator walks the source
iteratively and mirrors it as order-prefixed folders of link track
files (shared naming with queue persistence), tmp-and-swapped with
size caps so a runaway tree cannot fill the disk. One additive rpc,
CaptureLibraryNode(path, name), carries the flow; the TUI reuses the
input overlay prefilled with the selection title.
fsdy instances can now opt into an editable top level: root child
folders carry is_editable/is_deletable and support no-merge rename and
idempotent delete. /bookmarks mounts with it, and /queues too
(reserving current), so saved queues are renamable and deletable
through the existing e/d flows without TUI changes.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Queues now survive restarts, built entirely on the fs provider:
fsdy::Client is instance-mountable and a second, read-only instance
serves <config>/crabidy/queues/ as /queues. Every queue is a folder of
order-prefixed link track files plus a hidden state sidecar, written
only by the new QueueStore (tmp-and-swap). The playback loop streams
every queue change through a latest-wins watch channel to a debouncing
persister task and restores queues/current/ (tracks, position,
modifiers) at startup without autoplay. w on the queue pane asks for a
name and drives the previously stubbed SaveQueue rpc; reloading a
saved queue is just queueing /queues/<name>, since link entries
rewrite to their targets at listing time. The old "no links into /fs"
parse rejection gave way to one-hop link semantics so queues can
reference fs tracks.

.track.toml was too generic for files that only crabidy understands;
the cbd- prefix makes them unmistakable.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
A new fsdy crate exposes a configured root directory as /fs:
*.track.toml files are track nodes carrying metadata plus exactly one
playable reference — a local audio file, an http(s) URL, or a
crabidy-internal link. Link tracks rewrite Track.path to the target at
listing time, so playback routes through the existing prefix routing;
links into /fs are rejected, making chains impossible. Paths are
percent-encoded segments validated in one place (no root escape), the
orchestrator wires the provider optionally (a broken local config only
costs the /fs subtree), and the default chunked resolve walk provides
progressive queueing for free.

Resolving a nested node used to collect every track before the queue
changed: one broadcast at the very end, playback only after the full
walk, and the playback loop blocked for the duration. Now provider
resolution streams bounded chunks (tidaldy: one per 50-track page), the
playback loop applies and broadcasts each chunk as it lands, playback
starts with the first chunk, and Replace/Clear cancel in-flight
resolves down to the HTTP fetch. Queue.resolving (additive proto field)
drives an animated-dots pseudo-item in the TUI queue pane.
Also fixes Enter on a non-queueable library item blanking the queue
while audio kept playing, and the reversed album order left by the old
LIFO walk.

Search-term nodes created via % are now modifiable: e renames the
selected node (prefilled overlay; the new title re-runs the search,
colliding titles merge) and d deletes it, both gated on new additive
LibraryNodeChild.is_editable/is_deletable flags and marked [ed] in the
library list. Two new rpcs follow the create contract: RenameLibraryNode
returns the renamed node (the TUI navigates into it), DeleteLibraryNode
returns the refreshed parent listing. Queued tracks from a renamed or
deleted term keep playing; verified end-to-end against the live API.

Pressing % inside /tidal/search opens an input line; the entered term
becomes a tree node whose contents are the search results: track hits
queueable in place, artist and album hits as canonical /tidal/artists
paths. New CreateLibraryNode rpc + is_creatable flags (wire-compatible),
ProviderClient::create_lib_node routed by prefix, percent-encoded term
segments in crabidy-core, and a modal input overlay in the TUI with
creatable nodes marked [%]. Search terms live in memory for the process
lifetime; term nodes are deliberately not queueable so the resolve sweep
cannot drag whole discographies into the queue.

Pressing ? opens an overlay listing usage notes and every key binding.
The bindings now live in one declarative table (app/bindings.rs) that
both key dispatch and the help modal render from, so the help can never
drift from the real bindings. Includes the dev-flow design artifacts.

Records the current design in architecture/overview.md: crate topology,
the three concurrency domains and the channels between them, the
filesystem-like path addressing scheme, the span-carrying message
envelope used for tracing, and the Tidal device-flow auth.
Captures the trade-offs behind the load-bearing choices (paths vs opaque
ids, blocking engine thread, lossy broadcast) and the known gaps, so
later changes can see what was traded away.
Adds d2 to devenv for rendering the embedded diagrams.
