Real bundled server runtime evidence
Synthetic data only; no test runner used.

Bundled Node server: 16 independent cold runs, 32 cold/warm summaries with identical ordered buckets and diagnostics.

Two available CPUs: observed 0 transcript workers; canonical result match=True.
Injected SIGKILL into one directly observed transcript worker during an active real RPC.
[11:19:12.067] WARN (#1364): Usage transcript workers stopped; parsing transcripts in process.
Completed result after fallback: canonical match=True; tokens=43008000.
SIGTERM during scan: 2 observed workers; all exited=True; no incomplete usage-scan cache persisted=True.

Electron 44.10.1 (Node 24.22.1): real bundled server completed with 43,008,000 tokens and 24 malformed diagnostics.
Observed seven children: executable=electron, entry=dist/bin.mjs, command=__usage-transcript-worker, ELECTRON_RUN_AS_NODE=1.
