The connection-reachability + Subsonic network-guard helpers were pinned low by
four lib/api consumers (subsonicLibrary/Playlists/Ratings/Scrobble) yet ran two
lower-layer→feature inversions. Both removed without a registry:
- devOfflineBrowseStore is a self-contained DEV-only toggle with zero offline-
feature coupling — it was only colocated there. Relocated features/offline/store
→ store/ (global). The @/features/offline barrel re-exports it so feature/UI
consumers are unchanged; the three lower-layer readers (subsonicNetworkGuard,
activeServerReachability, useConnectionStatus) now import it from @/store directly.
- subsonicNetworkGuard's only other feature dep was playback's resolvePlaybackUrl,
used solely for the psysonic-local:// skip check. Added hasLocalPlaybackUrl to the
existing M4 substrate store/localPlaybackResolve — it mirrors resolvePlaybackUrl's
local-source branch exactly (same profile resolution; the empty-serverId playback
fallback never applies in the guard), so the skip stays bit-identical.
network/ (subsonicNetworkGuard + activeServerReachability + tests) → lib/network,
now @/features-free. useConnectionStatus is now iron-rule-clean and stays in hooks/
(cross-cutting). Test mocks retargeted to the new seam modules.
Behavior-adjacent (covered by suite; default paths identical): the local-bytes skip
helper — flag for offline-playback runtime QA alongside the M4 media-resolver seam.
