Trust
On the record.
Depth is only worth having if you can rely on it. These are the mechanisms that make an answer checkable, stated as behaviour rather than assurance.

02 · Deployment
Your data. Your walls.
Meridian runs where your data is allowed to be. What it needs from the environment underneath is written down and checked against each of these shapes, so whether it can run inside your walls is answered before anyone starts an investigation.
The same holds when the brain is reached from Claude or ChatGPT through the connector. Every request runs as the person who asked, under exactly the permissions and document clearance they hold in Meridian, and the log records who called what and when, never the question.
03 · Models
Models are plumbing.
All model traffic passes through one internal layer, and no part of the application talks to a provider directly. Cloud models, models taken directly from the labs, open models, your own custom deployments, or a mix. Which one handles a piece of work is decided by how sensitive the data is and where the system runs, never by lock-in.
04 · Isolation
Your brain is yours alone.
Every brain is its own isolated deployment: its own database, its own storage, its own credential, its own graph. There is no shared store and nothing joining one customer to another. We do not train models on your data, and it is never pooled with another business.
05 · The benchmark
What the structure is worth.
For anyone who wants to interrogate the machinery rather than take it on trust. Benchmarked internally against roughly eighty million transactional rows of real client data. Both numbers come from the structure, not from a better model.
40% → 100%
Correct answers. A frontier model pointed straight at the raw database gets six in ten wrong, and you cannot tell which six. On the same questions, the brain got every one right.
200s → 17s
Mean time to answer. Speed comes from knowing where to look rather than reading everything.
80m rows
The corpus it was measured against. Real operational data, not a synthetic set.
