platform

Serving 50 enterprise customers off one platform means four leak surfaces most designs miss, including the semantic cache and the eval set. A tier-by-tier isolation model with the noisy-neighbor math.

A staff-level platform design where the constraint set, not the architecture, is the test. The controls SR 11-7 actually demands, how to make audit a byproduct of the pipeline instead of a quarterly fire drill, and the v1 you can ship without a compliance finding.

A staff platform-design question about leverage, not metrics. The split between what the platform owns and what teams bring, the logging contract that makes everything else possible, and why the hardest problem is alert fatigue, not data collection.
