The device still jetsams with no stems log lines in the console, so stop guessing which stage eats the budget: log os_proc_available_memory headroom at analysis begin/end, separation task start, model ensure, ORT session load, every 10th inference window, and separation end. One run's console output now names the eater and its size.

What
The device still jetsams (~50 s after launch, mid-playback) and — importantly — the console shows no stems log lines at all, so it's not certain the separator is even the eater. Rather than tuning blind, this adds jetsam-debugging breadcrumbs.
How
New
MemoryFootprint.breadcrumb(_:)logsos_proc_available_memory(the process's remaining allowance before the OS kills it, categorymem) at:backfillTrackDetailsre-analysis path)What to do with it
Run once until the kill, then filter the console for
mem[. The last breadcrumbs before death name the stage and show the headroom slope:window Nlines → inference intermediates (next lever: shorter windows / model-side fix)ort session load→ model load (next lever: .ort format conversion)analysislines → the analyzer, not the separatormem[lines at all before death → the eater is outside ingest entirely (playback/UI), which redirects the investigationPlease paste the tail of the
mem[lines from a run that gets killed.🤖 Generated with Claude Code
