Balance checkpoint pauses against lost work using job-level interruption data, while accounting for asynchronous durability lag.

Turn the daily loss into recovery and replay costs, then identify which part is measured and which is assumed. Compare checkpoint cadence, recovery work and failure prevention without promising one universal floor.

Use the Llama 3 interruption record without turning job interruptions into device lifetime, predictable failures or a universal spare percentage.

Derive a checkpoint interval from measured job interruptions and exposed save cost. Trace durability, lost work and recovery before treating an estimate as goodput.
