The difference between a demo and a digital employee is what happens when things go
wrong. These are the protections that keep the system working after launch: each one a failure
I hit or saw coming, the mechanism that now prevents it, and the check that tells me it's still
alive. Not promises. Promises don't survive contact with production.
The model proposes, code disposes
Agents don't free-form their output. They call bounded Python verbs that do the actual work, so the same request produces the same result whether the model was sharp that day or not. Choosing the verb is the model's job; everything downstream of that is deterministic.
Tiered review: independent, not sequential
High-stakes extractions get reviewed a second time, blind to the first verdict, so the reviewer can't anchor on it. Disagreements escalate to a third opinion as tie-breaker instead of being averaged away.
A model swap has to earn its place
Model changes are gated behind a scored harness run on the real corpus, not vendor benchmarks. The last challenger lost to the incumbent and was rejected. Regressions get caught before they ship, not after someone notices bad output.
Multi-modal extraction, routed by content
Documents are routed by density: real text layers are parsed directly, scans and photographs go to a vision pass that reads classification and fields in one shot. Reader health is monitored, so a silently failing extractor surfaces instead of quietly emitting nothing.
Guarantees are tested like features
Safety paths get the same treatment as product code: the block logic carries a regression suite, and a nightly canary drives a real violation through the live system and alerts if it survives. That's how I found a gate that reported healthy and had never once fired. A protection nobody exercises is indistinguishable from one that's broken.
The system catches what I forget
Vendor updates silently overwrite local patches, so watchdogs re-apply them nightly and alert on drift. A coverage lint flags any patch I forgot to register for that protection. The failure mode it guards against is me.
