Summary

Converts the three densest list handlers (track_table.rs, library.rs, input.rs, plus ai_dj::open) to the shared Action vocabulary, so every non-cursor consequence of a key press is one app.apply(Action::…) line.

  • 10 new Action variants: PlayTrackInContext, SearchActiveSource, SearchPlaylistTracks, LoadMore(ListTarget), Open(OpenTarget), OpenLibrary(LibraryTarget), SelectSource(Source), OpenAddTrackDialog, OpenRemoveTrackDialog, RecommendFromTrack(TrackInfo).
  • LoadMore is the shared "hit the end of the list" consequence; it is self-guarding (no next page, active filter, or in-flight page all make it a no-op).
  • Library sidebar rows resolve by name through LibraryTarget::from_name instead of by position, so feature-gated rows no longer shift the indices of everything after them.
  • The moved consequences live on App: open_library_section, begin_add_track_to_playlist_flow_from_selection, begin_remove_track_from_playlist_flow, set_active_source, load_recommendations_for_track, open_ai_dj_screen, start_playback_track_in_context.
  • Action::Search stays on the Spotify catalog (the Lua spotatui.search contract). The terminal search box uses SearchActiveSource, which routes by the active browse source.
  • Source gains serde derives (the action wire shape).
  • Rider: the search-box cursor flickered at the 16 ms Home animation tick. The cursor is now hidden before the draw and positioned from inside the frame.

Three deliberate behavior changes, all in track_table.rs, everything else is 1:1:

  1. Random play (S) in a playlist table with no context id is skipped instead of sent as a bare resume with a random offset.
  2. Enter on a playlist row with no track id and no context id is skipped likewise.
  3. Random play in a Local or Subsonic playlist sends a one-item URI list instead of the track in the context slot. All four source routers treat both shapes as a one-track queue at offset 0.

Both cases 1 and 2 are unreachable through normal navigation (the table only opens with an id set).

Gates: app_field_writes_in_tui_handlers 386 -> 378, ioevent_refs_in_tui 125 -> 98, action_refs_in_tui_handlers 22 -> 54, test_attribute_total 1471 -> 1511.

Testing

On Windows:

  • cargo fmt --all -- --check: clean
  • cargo clippy --no-default-features --features telemetry,tui -- -D warnings: clean
  • cargo test --no-default-features --features telemetry,tui: 727 passed
  • cargo check --no-default-features --features telemetry (headless): clean
  • cargo check --no-default-features --features telemetry,tui,ai-dj: clean
  • cargo test --no-default-features --features telemetry,tui,local-files,subsonic,internet-radio,youtube: 808 passed, 1 failed (the known pre-existing Windows uri_round_trip)
  • tools/check_gates_ratchet.sh main: ok
  • The cursor fix was confirmed in the running app: the caret sits still in the search box on the Home screen with the banner animation on.

41 new tests in core/action/tests.rs cover every new arm differentially (the IoEvent each arm dispatches, the state it sets, and the no-op guards).

Additional notes

  • OpenTarget::Playlist { from_search: true } has no producer yet; the search-result handler adopts it in the next conversion batch.
  • select_device.rs still hand-writes the source switch; it moves to Action::SelectSource with the remaining handler files.
  • A test that switches the source must seed app.state_path; App::new leaves it None and save_runtime_state then writes the real state.yml. The one such test here seeds a tempdir.

Summary by CodeRabbit

  • New Features

    • Expanded library navigation for playlists, albums, artists, shows, local files, and AI DJ.
    • Added source-aware searches, playlist-track searches, pagination, and track-based recommendations.
    • Added playlist track add/remove workflows with confirmation dialogs.
    • Added music-source switching and context-aware track playback.
    • Improved AI DJ setup and library indexing.
  • Bug Fixes

    • Fixed terminal cursor flickering during animated screen updates.
    • Improved handling of empty playlists and invalid navigation selections.

Convert track_table.rs, library.rs and input.rs (plus ai_dj::open) to the
shared Action vocabulary: PlayTrackInContext, SearchActiveSource,
SearchPlaylistTracks, LoadMore(ListTarget), Open(OpenTarget),
OpenLibrary(LibraryTarget), SelectSource, OpenAddTrackDialog,
OpenRemoveTrackDialog and RecommendFromTrack. Library rows resolve by name
instead of position. The moved consequences live on App.

Three deliberate behavior changes, all in track_table.rs: a random play or
Enter with no context id is skipped instead of sent as a bare resume with an
offset, and the Local/Subsonic random play sends a one-item URI list instead
of the track in the context slot (the routers treat both as a one-track
queue).

Gates: app_field_writes 386 -> 378, ioevent_refs_in_tui 125 -> 98,
action_refs 22 -> 54, tests 1471 -> 1511.
ratatui flushes the buffer diff first and positions the cursor afterwards,
so a cursor left visible by the previous frame rode over every rewritten
cell; on the 16 ms Home animation tick the banner rewrites most of its
cells each frame, which showed as a strobing block. The post-draw
show/hide pair also reset the blink phase on every frame.

Hide the cursor before the draw, and request its position from inside
the frame when the input box is focused, so ratatui shows it once after
the flush.

📝 Walkthrough

Walkthrough

The PR expands the Action model and routes TUI operations through App::apply. It centralizes library, playlist, AI DJ, source, playback, search, and recommendation workflows. The TUI runner also changes cursor handling during frame rendering.

Changes

Action routing

Layer / File(s) Summary
Action contracts and dispatch
src/core/action/..., src/core/app/discover.rs, src/core/app/route.rs, src/core/app/transport.rs, src/core/source.rs, .github/copilot-instructions.md, AGENTS.md, CLAUDE.md
The action vocabulary now includes source-aware searches, context playback, pagination, resource opening, library navigation, playlist dialogs, recommendations, and source selection. App applies these actions and dispatches the corresponding events.
Application workflow handlers
src/core/app/library.rs, src/core/app/dj.rs, src/core/app/playlists.rs, src/tui/handlers/ai_dj.rs
App now centralizes library navigation, AI DJ indexing, playlist add and removal staging, recommendation loading, and source-specific state changes.
TUI action integration
src/tui/handlers/input.rs, src/tui/handlers/library.rs, src/tui/handlers/track_table.rs
TUI handlers now use actions for searches, resource opening, library navigation, pagination, dialogs, saving, recommendations, and playback.
Action behavior validation
src/core/action/tests.rs, src/tui/handlers/library.rs, src/tui/handlers/track_table.rs, src/core/source.rs, tools/gates.count
Tests cover action paths, state changes, event dispatch, invalid inputs, persistence, feature-gated routes, source serialization, and migration counters.

Cursor rendering

Layer / File(s) Summary
In-frame cursor lifecycle
src/tui/runner.rs
The runner hides the cursor while writing frame updates and positions the input cursor inside the draw closure. Direct post-draw cursor movement was removed.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to ec293

The refactor centralizes list actions, but the current head still has bounded correctness issues: playlist removal may show a misleading message instead of opening confirmation, and selected playback may target the wrong track when filtering is active. These should be fixed or explicitly accepted before merging.

Consider pinning the serde-token claim with a test.

The doc states the derived unit-variant strings coincide with to_config_str(). Nothing enforces that today. A variant rename would break the claim silently. A small test in the existing mod tests closes the gap.

Consider testing the three-condition index guard.

request_dj_library_index dispatches only when avoid_library is true, library is None, and library_indexing is false. The doc comment says the guard exists to keep a multi-second crawl off the serial IoEvent lane, so a regression here is a head-of-line-blocking bug, not a cosmetic one. The colocated mod tests currently covers queue behavior only. Three small cases would pin it.

As per coding guidelines: "Add/adjust tests when changing behavior".

Consider a test for the Friends arm's conditional dispatches.

This arm has the most branching in the method: two guarded dispatches plus a timestamp write. The visible tests cover the Stats and Liked Songs arms only. A test that asserts GetFriendCode and GetFriends fire on a cold App, and that neither fires when friend_code is set and friends is non-empty, would pin the moved behavior.

An empty playlist reports a total of 0 and `random_range(0..0)` panics,
which took the TUI down with the terminal still in raw mode. Skip the
start instead, pinned by a handler test.

Also from review: the frame cursor arithmetic is a pure function with two
tests, `open_ai_dj_screen` is `pub(super)`, and a test pins that the
`Source` serde tokens equal the config tokens.

@coderabbitai on the four nitpicks:

  • src/core/source.rs serde tokens: test added in abdf330 (serde_tokens_match_the_config_tokens, iterates Source::ALL).
  • src/core/app/dj.rs open_ai_dj_screen visibility: now pub(super) in abdf330. request_dj_library_index stays pub(crate) because the terminal handler calls it.
  • src/core/app/dj.rs request_dj_library_index guard: already covered by the handler tests that drive it, toggling_fresh_only_starts_the_crawl_once and opening_the_screen_with_the_filter_already_on_starts_the_crawl in src/tui/handlers/ai_dj.rs (the dispatch, and the once-only guard).
  • src/core/app/library.rs Friends arm: already covered in src/core/action/tests.rs by open_library_friends_first_open_fetches_code_and_list (cold App dispatches GetFriendCode and GetFriends) and open_library_friends_skips_fetched_state_on_reopen (neither fires once loaded or loading).

372-379: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Compute the selected offset after URI filtering.

At Line 372, uris removes rows with no URI. At Line 378, selected_index still addresses the original tracks vector. If a Local, Subsonic, or YouTube row lacks a URI, Action::PlayUris receives an offset for a different row or beyond the list. Track the selected offset while collecting URIs, and dispatch only when the selected row is playable.

Proposed fix
-        let uris: Vec<String> = tracks.iter().filter_map(|t| t.uri.clone()).collect();
-        if !uris.is_empty() {
+        let mut uris = Vec::new();
+        let mut selected_offset = None;
+        for (row_index, track) in tracks.iter().enumerate() {

@coderabbitai on the second round:

  • src/tui/handlers/track_table.rs 372-379 (selected offset after URI filtering): declined. The lines are outside this PR's diff; the conversion only swapped the dispatch for Action::PlayUris and kept the offset logic as it was. The in-line comment states the invariant, and the three loaders hold it: every row the Local, Subsonic and YouTube tables show is built with uri: Some(..) (src/infra/local/mod.rs lines 379 and 430, src/infra/subsonic/mod.rs line 405, src/infra/youtube/mod.rs line 378). The filter therefore keeps every row and the index lines up. The Spotify arms above it (RecommendedTracks, SavedTracks, AlbumSearch) already track the offset while they collect, because Spotify rows can lack a URI (local files). Rewriting the decoded-source arm the same way would be a behavior-neutral hardening outside this PR's 1:1 contract; noted as a follow-up candidate.
  • src/core/source.rs deserialize side: done in ec29301, the test now round-trips each token through serde_json::from_str as well.

@LargeModGames, verified.

serde_tokens_match_the_config_tokens now validates both serde serialization and deserialization for every Source::ALL value.

The Local, Subsonic, and YouTube loaders construct their displayed TrackInfo rows with uri: Some(...). Therefore, URI filtering does not change the selected offset in these playlist contexts. I withdraw that concern.

Learning: For `TrackTableContext::LocalPlaylist`, `TrackTableContext::SubsonicPlaylist`, and `TrackTableContext::YouTubePlaylist` in `src/tui/handlers/track_table.rs`, displayed `TrackInfo` rows have a URI by construction. `src/infra/local/mod.rs`, `src/infra/subsonic/mod.rs`, and `src/infra/youtube/mod.rs` each create these rows with `uri: Some(...)`, so filtering URI values preserves `selected_index` alignment for `Action::PlayUris`.

@LargeModGames, verified.

Source::ALL serde serialization and deserialization coverage addresses the serde-token concern.

App::open_ai_dj_screen is now pub(super). App::request_dj_library_index remains pub(crate) because src/tui/handlers/ai_dj.rs calls it.

The named AI DJ tests verify both dispatch paths and the no-repeat guard.

The Friends tests verify first-open dispatches and no dispatch when the friend code exists and loading is active.

Learning: In the AI DJ feature, `App::request_dj_library_index` in `src/core/app/dj.rs` must remain `pub(crate)` because `src/tui/handlers/ai_dj.rs` calls it. The method dispatches `IoEvent::DjIndexLibrary` only when `app.dj.avoid_library` is enabled, `app.dj.library` is `None`, and `app.dj.library_indexing` is false. Handler tests `toggling_fresh_only_starts_the_crawl_once` and `opening_the_screen_with_the_filter_already_on_starts_the_crawl` cover these dispatch paths and the cached-index guard.

@coderabbitai one thread is still open: src/core/app/playlists.rs current_playlist_removal_target (the fallback playlist name). Please verify the claim there: the body is a verbatim move of current_playlist_target_for_track_table_context plus playlist_name_for_id from src/tui/handlers/track_table.rs on main, including the ? on the name lookup, so a fallback name would be a behavior change in the removal flow and outside this PR's 1:1 contract. It is noted as a follow-up.

@LargeModGames, verified.

App::current_playlist_removal_target is the moved main logic with current_playlist_id_static and playlist_name_for_id inlined.

The Spotify playlist-name lookup still ends with ? in src/core/app/playlists.rs Line 313. If neither all_playlists nor search_results.playlists contains the playlist, the helper returns None. The removal flow then keeps the existing early return and status message.

A fallback name in this Spotify path would change the removal behavior. It is outside this PR's 1:1 move.

The YouTube playlist fallback remains in the separate YouTube path. It also existed on main.

Learning: For Spotify playlist-track removal, `App::current_playlist_removal_target` in `src/core/app/playlists.rs` preserves the former `src/tui/handlers/track_table.rs` behavior. It resolves the playlist name from `App::all_playlists` or `App::search_results.playlists` and uses `?` on that lookup. If no name is available, the removal flow returns with the existing "Remove only works in selected playlist views" status instead of using a fallback name. The separate YouTube removal path has a pre-existing `"YouTube playlist"` fallback.
