Broque Thomas	e20994e1c7	Manual picks: stream results, don't auto-retry, fix stuck-at-0% ... Three follow-on fixes to the manual-search candidates modal once people started actually using it: 1. NDJSON streaming. Manual search waited for every source to return before showing anything. Now streams one event per source as each completes — header line, source_results per source, done terminator. Frontend appends rows incrementally via response.body.getReader(). 2. Manual picks no longer auto-retry on failure. New _user_manual_pick flag set on the task in /download-candidate. Both monitor retry paths (not-in-live-transfers stuck + Errored state) bail on the flag. Surfaces the failure to the user instead of silently picking a different candidate via fresh search. 3. Non-Soulseek manual picks (youtube/tidal/qobuz/hifi/deezer/ soundcloud/lidarr) no longer stuck at "downloading 0%" forever. The live_transfers IF branch now marks manual-pick tasks failed directly when the engine reports Errored, instead of deferring to the monitor (which bails on manual picks). Engine fallback in else branch covers the rare race where the orchestrator's pre-populated transfer lookup is missing the entry. Plus a deadlock fix discovered along the way: the new failure path synchronously called on_download_completed while holding tasks_lock, which itself re-acquires the same Lock — non-reentrant threading.Lock self-deadlocked the polling thread. While wedged, every other endpoint that needed the lock (including /candidates → other failed rows couldn't open modals) hung waiting. Moved completion callbacks onto a daemon thread so the lock releases first. Plus failed/not_found/cancelled rows are now ALWAYS clickable (not just when the auto-search cached candidates) — the modal carries the manual search bar, which is the user's recourse for empty results. Plus manual download worker now runs on a dedicated thread instead of competing with the batch's 3-worker missing_download_executor pool — saturated batches no longer queue manual picks indefinitely. All scoped to manual picks via the _user_manual_pick flag — auto attempt flow byte-identical to before. Engine fallback gated on the flag too so auto attempts in the else branch keep the original do-nothing behavior (safety valve handles the stuck-forever case). Also dropped _handle_failed_download from web_server.py — defined but had no callers (dead code). 17 new unit tests pin the gate behavior: - engine fallback: Errored/Cancelled/Succeeded/InProgress transitions, manual-pick gate, terminal-state skip, soulseek skip, missing download_id skip, engine returning None, orchestrator exception - monitor: manual-pick skips not-in-live-transfers retry + Errored retry - IF-branch end-to-end: Errored marks failed, "Completed, Errored" hits failure branch, auto attempts defer to monitor Manual-search endpoint tests rewritten for NDJSON: 11 cases (validation, single-source dispatch, parallel "all" dispatch, one-event-per-source streaming shape, unconfigured-source skip + reject, header metadata, per-source exception isolation).
