Tangent runs (numerics.tangent): integrate the derivative of the run with respect to a relative change of the prescribed peak forces by forward-mode differentiation of the step; its sound, probes, frames and an energy norm per block are stored in the .cymsim file (group tangent), and tangent runs continue and are cut like plain runs

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
