Bounds + AqtaCore

How the full stack works

Most tools audit after the fact. AqtaCore runs before the action. It signs the call and what the model decided, and anyone can verify that receipt offline, with no access to us.

  1. 01The input

    A sensitive document

    Personal data you cannot send to a model as is.

  2. 02On-device

    Bounds strips PII and logs what it removed

    Redacted on-device, with an unsigned record of what was removed.

  3. 03The gateway

    The clean document enters your LLM via AqtaCore

    One gateway in front of every model provider.

  4. 04The receipt

    AqtaCore signs the call and what the model decided

    A receipt per call: request hash, policy applied, model, outcome. Signed with Ed25519.

  5. 05The audit

    An auditor verifies the signed receipt offline

    Receipt B verifies against one published key. The redaction record is reviewed alongside it.

Proof · Public ledger · W19

We published the claim first.
Anyone can check it.

8 daysbefore the WHO declared a public-health emergency on 17 May 2026, the DR Congo Ebola rank was already in our public, timestamped git ledger. Signed before the moment it mattered, verifiable by anyone.

AqtaBio, our public-health research programme, commits every forecast to a public git ledger before the outcome window closes, so the claim cannot be backdated. The same receipts pattern as the product: signed before the moment it matters, verifiable without us.

Orange = the five highest-risk Ebola tiles in the W19 commit. DR Congo at rank 4.

Congo Basin · 6×5 tile lattice top-5 elevated baseline

Bootstrap p = 0.222; we publish rank before the outcome window. The contribution is the primitive, not a claim of predictive capability.

9 May 2026

AqtaBio · W19 commit

Five Congo Basin ebola tiles, listed in an append-only public git ledger. Three in Central African Republic and Republic of the Congo, DR Congo at rank 4.
