The seven remaining src/api/ modules (analysis, azuracast, bandsintown,
coverCache, migration, network, runtimeLogs) were the last IPC-layer files
outside src/lib/api/, where the rest of the FE IPC clients already live. Move
them (+ the colocated coverCache test) into lib/api and repoint every consumer;
relative-up imports in the moved files become the depth-independent @/ alias.
Pure move + import updates — no behavior change. The layering baseline is
regenerated in the same commit: the moved files' pre-existing store/cover edges
are only now caught under lib/, and the cover<->coverCache cycles are the same
edges re-keyed to the new path (E4 shrinks the allowlist later).
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.
Pull findLocalPlaybackUrl/findLocalPlaybackEntry/hasLocalPersistentPlaybackBytes
+ the entry/index-key membership helpers (entryBelongsToServer,
indexKeyBelongsToServer, findFavoriteAutoEntry, hasLocal{Library,FavoriteAuto}Bytes)
out of features/offline/utils/offlineLibraryHelpers into a new core module
store/localPlaybackResolve.ts. The substrate depends only on authStore +
localPlaybackStore + serverIndexKey utils (no useOfflineStore), so the audio
core can resolve on-disk bytes without inverting into @/features/offline.
Repointed the audio-core consumers (crossfadePreload, playbackUrlRouting,
resolvePlaybackUrl, playTrackAction, promoteStreamCache, hotCachePrefetch,
hotCacheStore) + offline-internal callers + favorites hook; moved the two
barrel vi.mocks onto the new leaf module. offlineLibraryHelpers re-imports the
two primitives it still needs internally.
Decouple Step 2a. Removes the local-bytes offline edge from the audio core;
the resolve* media-resolution family (Step 2b) + orbit seam (Step 3) remain.
tsc 0, lint 0, full suite 319/2353 green.
Move domain-agnostic, feature-free helpers out of the flat utils/ and store/
roots into src/lib/ (plan M4, §3 lib/ layer):
- lib/format/: formatBytes, formatClockTime, formatDuration, formatHumanDuration,
relativeTime (pure format/date/byte/clock helpers)
- lib/i18n.ts: i18next bootstrap (global app infra)
- lib/util/: sanitizeHtml, platform, dedupeById, safeStorage (pure helpers +
the zustand storage adapter)
playbackScheduleFormat stays in utils/format (runtime usePlayerStore dep =
audio-core coupling, not generic). formatClockTime keeps a type-only
@/store/authStoreTypes import (erased, no runtime inversion — accepted per the
deviceSync precedent).
Pure move via deep @/lib/* specifiers (no barrel → no mock-collapse surface).
tsc 0, lint 0/0, full suite 319 files / 2353 tests green.
Tooling note: lib_move.py regex extended to also rewrite side-effect imports
(import './i18n') and vi.importActual paths — both were silent gaps.
Move the 5 subsonic api modules that M3 had co-located into features
(subsonicAlbumInfo/Artists/Playlists/Radio/Statistics) into src/lib/api/, the
feature-free infra layer, and drop their feature-barrel re-exports. Consumers
now import these protocol calls directly from @/lib/api/subsonic*; the feature
barrels export only domain UI/hooks/state.
This is the consistent api placement (plan §10.3, revised: ALL subsonic protocol
clients are feature-free infra, not per-feature) and it kills the documented
api-induced feature<->feature cycles: offline->artist/playlist (getArtist/
getPlaylist*), album->artist (getArtistInfo), deviceSync/nowPlaying/orbit->*.
Remaining artist<->album refs are UI-only (OpenArtistRefInline/coerceOpenArtist
Refs) and offline->playlist is store-level (usePlaylistStore) — both deeper,
tracked for M5, not api placement.
Pure move: import specifiers + vi.mock/spy targets repointed; no behaviour
change. tsc 0, lint 0/0, full suite 319 files / 2353 tests green.
Tooling note: barrel-imported and dynamic-import api symbols were split out of
@/features/* to @/lib/api/* (tsc-driven); 12 vi.mock barrels retargeted to the
deep lib module (mock-collapse sweep), AlbumHeader's UI mock left untouched.
Move the Subsonic + Navidrome protocol clients and the library IPC facade
(subsonic*, navidrome*, library.ts + tests) from src/api/ into src/lib/api/,
the feature-free infra layer (plan M4, decision §10.3: shared client core → lib/).
Pure move: deep-path import specifiers @/api/* -> @/lib/api/* across ~150
consumers; no behaviour change. Domain REST (lyrics/events) and cover/analysis
infra stay in src/api/ pending their own M4 placement.
tsc 0, lint 0/0, full suite 319 files / 2353 tests green.
