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.

A new rssdy crate mounted at /rss. Subscriptions are (name, url) pairs in
rss.toml; `%` on /rss takes a pasted feed URL, fetches it once, names the
subscription from the feed's own title and persists it, `e` renames, `d`
unsubscribes without touching captured audio. Feeds are read as RSS
2.0/1.0/0.x, Atom or JSON Feed through feed-rs.
**A premium feed URL is the credential.** Library paths are displayed,
logged, and persisted into saved queues and bookmark tomls, so a URL in one
leaks into all of them. Paths therefore carry a slug of the subscription name
plus blake3(guid)[..16] — /rss/the-economist-podcasts/676f8bfa48c9cac3 — and
URLs are redacted from every Debug impl and kept out of errors (reqwest goes
through without_url).
**Nothing is cached, at either end.** A listing always fetches. The half that
is easy to miss is client-side: both clients cache listings by path and only
/crabidy, /fs and /orphans bypassed it, so /rss joins MUTABLE_ROOTS in both —
otherwise a re-visit answers from the client and the server's freshness is
invisible. One memo, written by listings and read only when resolving a track
(bounded to 8 feeds), keeps queueing 40 episodes at one fetch instead of 41
without a TTL to guess at.
Verifying against the user's real Economist feed caught a bug no unit test
would have: feed-rs parses <itunes:duration> as NPT, which has no MM:SS form,
so "53:25" fell through to its leading-number regex and a 53-minute episode
reported 53 *seconds* ("1:20:40" happens to parse fine). That field is now
recovered from the raw body — a shallow scan keyed by guid and enclosure URL —
and the live feed reports 3205/2830/1662 s, matching 53:25/47:10/27:42.
Bounded by design: per-request timeout, an 8 MiB body cap enforced while
reading chunks rather than after the fact, an episode cap, newest-first
enforced at the provider boundary so any backend obeys it. A malformed entry
is skipped; only an unfetchable feed errors, and it fails that node alone.
Behind a default-on `rss` cargo feature like every other provider, with a row
in check-features. Documented in docs/src/providers/rss.md and
rssdy/README.md, both stating plainly that the URL is a credential, that
listings are never cached, and that bookmarks depend on publisher guids —
capture what you want to keep.

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.

Brings the web client level with the TUI in the same change rather than
deferring parity again — which also closes the library visual mode that was
left out when v/V landed in the terminal.
The web queue owns no list (just a cursor, with rows rendered straight from
the server signal), so its marks live on QueueCursor beside the snapshot:
mark flags plus the paths they were taken against, carried across each
update by the same greedy in-order path match the TUI uses. Same rule, same
seven reconciliation cases tested here too, so the two clients cannot drift.
Adds s / v / V / y / p / P in the queue, v / V / y in the library, marks
rendered on queue rows, register count in the queue toolbar, and the visual
auto-leave rule. The "insert" button became "paste". Library movement now
paints in visual mode — a dead-code warning on the wasm target was what
caught that it did not.
Docs: the TUI page gains a register section (what it is, and that it is per
client, one slot, and re-resolves paths on paste), the web page points at
it, queue.md explains why Remove takes positions and Insert takes paths,
and the README walkthrough covers the keys. All of them state plainly that
p changed meaning.
Verified on both targets: cbd-web clippy is clean for native *and*
wasm32-unknown-unknown (mod app only compiles for wasm, so native alone
proves nothing), 20 tests pass, and the trunk bundle builds.

delete_needs_confirmation only ever returned true for /captures paths,
and /captures stopped existing when saved queues, bookmarks, and captures
folded into the single /crabidy provider. So the y/N dialog could not
open, the web client already deleted immediately, and its comment
claiming to mirror the TUI described an arrangement neither client had.
Removed rather than re-pointed at /crabidy: a delete there drops the
metadata toml only, never the shared store audio, which survives and
resurfaces under /orphans — so there is little to guard. Both clients now
behave the same, which is what the docs describe.
Gone with it: the Dialog::ConfirmDelete variant, the ConfirmDialog
component and its keyboard handler, the test, and the two CSS rules only
that dialog wore (.danger-dialog and the solid .danger button;
.ghost.danger stays, three row actions still use it).
Verified: clippy clean for wasm32 (where `mod app` actually compiles) and
native, 12 cbd-web tests pass, and the trunk bundle builds.

The docs drifted behind three changes: the /queues + /bookmarks +
/captures split folding into one /crabidy provider, three providers
arriving (soundcloud, jamendo, abs) with nothing written about them, and
the spectrum toggle moving off v to f when library visual mode took v/V.
- The book gains a page per undocumented provider — /soundcloud,
/jamendo, /abs — each with its tree, its playback path, every config
option, and how to log in. The providers index and intro list all nine
roots in the order the server actually serves them.
- Every provider now documents its login: Tidal's device flow (and that
a broken tidaly.toml is the one fatal provider config), audiobookshelf
API keys, the optional SoundCloud token and where to read it out of a
browser, YouTube cookie exports, Jamendo's shipped key, and "nothing
to do" for fyyd and /fs.
- fsdy's README described three server-managed mounts under
~/.config/crabidy that have not existed for a while; it now describes
/crabidy over the state dir plus the shared content store, and how
deletes there never touch store audio.
- Stale /captures/<name> save paths in the tidaldy and ytdy READMEs are
/crabidy/<name>. The TUI key table, the README walkthrough, and the
spectrum section use f, and visual mode (v/V) is documented.
- config.md and the README list all seven provider config files, say
plainly that credentials are stored in cleartext, and cover the audio
output device; the CLI page documents audio-devices and features.
- No README or docs page references architecture/, quality/, or plan/
any more: the book describes the system as it is, and points at the
crate READMEs for usage and config.
- devenv-docs.nix was never committed even though devenv.nix imports it,
so a fresh clone could not enter the shell at all. It is in now, which
also makes the README's `devenv shell -- docs` work.
Also fixes two ./store.md links in providers/fs.md that pointed one
directory too shallow.

The now-playing clock rendered raw milliseconds as seconds, so a 3:04
track read as 3070:32. TrackPosition carries milliseconds (the TUI wraps
it with Duration::from_millis); convert ms to seconds at both display
sites. The progress gauge already used a position/duration ratio, so it
was unaffected. format_seconds now zero-pads minutes and rolls into
h:mm:ss past an hour, matching the TUI's now-playing pane.

Moving the library or queue cursor with the keyboard (j/k, page keys,
first/last) updated the selection but never scrolled the list, so the
selected row could slide out of the scroll box and disappear.
Each pane now runs an effect that re-scrolls its `.selected` row into
view whenever the cursor moves. The queue cursor is its own signal, so
this fires on moves but not on every stream-driven queue refresh; the
library cursor lives in the library pane signal. The scroll is deferred
to the next animation frame (the freshly-rendered row must be in the
DOM) and uses `block: nearest`, so an already-visible row does not jump.
Click/drag selection needs no help -- the pointer is already on-screen.

Relying on the proactive prompt alone was not enough: it only fires on
first connect, only when no credentials are stored, and only against an
auth-enabled server, so a manual affordance was missing.
The top bar now shows a "log in" button whenever the server reports auth
is enabled (Init.auth_enabled, kept in a store signal), opening the same
dismissible credentials dialog. Once credentials are stored it becomes
"log out", which clears them and reloads to drop back to the guest role.
The button is hidden on servers with no auth, where sending credentials
would only earn an UNAUTHENTICATED lock-out.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.
Docs: architecture/roles-auth.md and web-client.md updated.

The clients cache library listings except for server-mutable folder roots.
/orphans is recomputed from the store on every visit, so a cached listing
froze the orphan set until a client restart. Add /orphans to the TUI's
mutable-roots list so entering the provider always re-walks.
The web client's list was also stale from the store refactor — it still
named the removed /captures, /queues, /bookmarks providers and omitted
/crabidy, so /crabidy (and now /orphans) listings went stale there too.
Reset it to the real mutable roots: /crabidy, /fs, /orphans.

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.

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.

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.
