Reframed M6 from "extract psysonic-commands" to "place each domain's
Tauri commands in its own domain crate" — the original psysonic-commands
proposal would have been a thin shell with no clear domain ownership
because each prior milestone already kept its own commands inline:
audio_*_commands in psysonic-audio
cache/sync commands in psysonic-syncfs
navidrome/discord/etc in psysonic-integration
The leftover analysis admin commands (7 of them) logically belong to
the analysis domain. So they move there:
src/lib_commands/app_api/analysis.rs →
crates/psysonic-analysis/src/commands.rs
WaveformCachePayload + LoudnessCachePayload moved out of top-crate
lib.rs into commands.rs
PlaybackQueryHandle gets a second closure (`should_defer_backfill`) so
analysis_enqueue_seed_from_url can ask "is a ranged playback already
going to seed this track?" without depending on psysonic-audio.
Top crate keeps the shell-flavored commands (window/tray/mini-player,
greet/exit_app, mpris/global-shortcuts/check_dir_accessible, perf,
cli_bridge) for M7 to clean up.
Behaviour preserving. Cargo check + clippy --workspace clean.
Moves analysis_cache + analysis_runtime out of the top crate into a new
psysonic-analysis crate, plus the runtime user-agent facade into
psysonic-core. The audio↔analysis dependency cycle is broken via a
PlaybackQueryHandle port registered as Tauri State.
crates/psysonic-analysis/ new lib crate
src/analysis_cache/{mod,store,compute} unchanged behaviour
src/analysis_runtime.rs + enqueue_analysis_seed (was
in lib_commands/cache/offline)
crates/psysonic-core/src/
user_agent.rs subsonic_wire_user_agent +
runtime/default helpers
(was in top lib.rs)
ports.rs PlaybackQueryHandle: closure
wrapper, not Arc<dyn Trait>,
so existing State<AudioEngine>
callsites stay unchanged
The shell setup hook registers the real PlaybackQueryHandle once the
AppHandle is available; the closure captures it and re-resolves
AudioEngine via try_state at each call.
Top crate keeps `crate::analysis_cache`, `crate::analysis_runtime`,
`crate::subsonic_wire_user_agent`, and `crate::submit_analysis_cpu_seed`
working via re-exports — no audio/lib_commands callsite needed editing.
Behaviour preserving. Cargo check + clippy --workspace clean (only
pre-existing warnings carry over).
