The prefetch worker / replan orchestration and its shared module state
(pendingQueue, workerRunning, debounceTimer, graceEvictTimer) stay
entirely untouched in hotCachePrefetch.ts. Extracted only what does not
touch that state:
- hotCachePrefetch/helpers.ts pure helpers — entryKey, byte
estimators, debounceMs, frontend
debug log, PREFETCH_AHEAD, PrefetchJob
- hotCachePrefetch/analysisPrune.ts self-contained analysis-queue prune
cluster (its own analysisPruneTimer +
lastAnalysisPruneSig state, fully
encapsulated behind a
resetAnalysisPruneState wrapper)
Verbatim moves. The orchestration core diff is import-block + the three
analysis-cleanup lines collapsing to resetAnalysisPruneState() — nothing
else. The MainApp call site imports initHotCachePrefetch unchanged.
