reliability

Trace a changed BF16 bit, distinguish corrected and uncorrectable errors, and calculate recovery cost without assuming every device has the same ECC overhead.

Estimate replacement demand over replenishment time, then size for shortage risk and failure correlation. Distinguish shelf parts from runnable spare nodes.

Keep the full failure history and investigate what changed. One passing retry is evidence, but it is not a repair or an acceptance policy.

Inventory a resumable checkpoint instead of rounding its bytes per parameter. Trace snapshot stall, durable drain and publication, then calculate the storage floor.

Explain a reliability concern with evidence, a specific proposal and an honest outcome. Show how you weighed the cost of delaying a launch and what changed afterward.

Show a cost reduction with comparable service evidence, realized savings and a feasible recovery plan. Distinguish a quiet trial from proof of unchanged reliability.
