The single largest handler in server.py — the 902-line /ws/highway/{filename}
chart streamer — plus its 3 exclusive helpers (_pick_smart_arrangement,
_sanitize_authors, _sanitized_song_offset). server.py: 9,008 -> 8,003 (-1,005,
the biggest single R3 cut).
Clean move despite the size: the handler's only server-module deps are the 4
path constants + 3 exclusive helpers + app + log. Everything else it uses is
either NESTED inside the handler (_evict_audio_cache, _fill_scale_degree,
_manifest_entries, _tone_names, _xml_rank, _send_keepalives) or imported from
the shared lib modules (song/audio/sloppak/drums/notation/dlc_paths/metadata_db).
- Path constants read through the appstate seam: added static_dir /
sloppak_cache_dir / audio_cache_dir slots (config_dir already there);
server.py configures them. Bodies otherwise verbatim (@app.websocket ->
@router.websocket, PATHS -> appstate.*, log -> module logger).
- sloppak_cache_dir IS setattr-patched, so the 3 test_highway_ws_* suites now
also `setattr(appstate, "sloppak_cache_dir", ...)` next to their existing
server patch. _sanitize_authors unit tests import it from routers.ws_highway
(it moved). No other test churn.
- Removed 23 now-dead imports from server.py (song/audio/drums/notation/
bisect/contextvars/structlog/WebSocket*/_arr_smart_sort_key) — diffed against
the origin/main unused-import baseline so only NEWLY-dead ones went.
owns_tmp (assigned, never read) moved verbatim — it's pre-existing dead on
origin/main too; left as-is to keep the move faithful.
Verified: route table identical to origin/main (143, paths/methods/order);
handler body verbatim spot-checked; pyflakes clean (server has no new
undefined/dead); pytest 2400 passed; packaging guard 53; eslint 0. Boot smoke:
the highway WS streams the full chart (song_info/beats/sections/notes/chords/
notation/anchors/drum_tab -> ready) BYTE-for-byte the same message sequence as
origin/main across arrangements 0/1/2, zero tracebacks.

Root cause of the flaky pytest segfault (exit 139): the background scan and enrichment daemon threads (_scan_runner/_enrich_runner) use the shared MetadataDB connection, but test fixtures closed that connection in teardown without stopping them. A daemon thread mid-query on a freed SQLite conn is a native use-after-free → SIGSEGV. The app's startup kicks a scan, so almost any app-booting fixture was vulnerable. It only surfaced now because got-feedback/feedBack#728 added a push trigger, so ci/test runs on every push to main.
Fix: server.py retains the scan/enrich thread handles and adds _join_background_db_threads(); every test fixture now joins the workers before conn.close(). Verified: the full suite runs to completion (no segfault) where it previously crashed at ~25%.

Surface the feedpak manifest `authors` list (spec §5.4) on the highway: a credits card ("Charted by Azure") shown over the highway when a song loads, riding the count-in / a ~3s hold and dismissed when playback starts. Gated to fresh feedpak plays only (minigames, loose/archive, arrangement switches, seeks, replays excluded). Includes a 12s backstop so the overlay never lingers if playback fails to start.
Closes#628. Reviewed by Codex (3 passes, converged). Verified locally: pytest 9/9, node --test 23/23, headless-browser end-to-end.
