Store signals (audio, probes, displacement frames) in the run's precision, float64 for a float64 run; run the tests on the CPU, where runs are reproducible bit for bit

Run cache: upload the partial run every --upload-every seconds of wall time (default 600), so that a killed job continues from its last upload; Simulator.run(checkpoint=...)

Run cache, write path: with CYMSIM_CACHE_KEY a computed run is uploaded unless the entry holds at least as many steps; per-segment device, jax, commit and host in the entry metadata; failed uploads are logged, not raised

Run cache, read path: cymsim run --cache URL (CYMSIM_CACHE_URL), simulate(cfg, cache=URL); a covering entry is cut without building the model, a shorter one is continued; local copies revalidated by ETag

Cache keys for runs: hash of the non-default config fields without duration, energy-report cadence and output naming, with MODEL_VERSION; cymsim cache-key

Continue a run from a .cymsim file (cymsim run --resume, simulate(cfg, resume=...)), identical to the uninterrupted run; keep the outputs past the duration in the state and store probe signals in the file
