Where CEYO sits in the stack.
CEYO is designed to operate beside inference workflows, not as a replacement for decision authority and not as a default dependency on model internals.
The platform posture is explicit: attach at a defined boundary, apply policy-scoped capture, canonicalize deterministically, seal under operator key custody, and preserve independent verification under constrained disclosure.
- CEYO can be deployed as a sidecar, gateway, or wrapper.
- Private signing keys remain in the operator environment.
- Fail-open posture can preserve inference continuity when sealing fails.
Supported attachment models.
CEYO is not tied to a single product architecture. The platform can be positioned at different operational boundaries depending on latency tolerance, review requirements, and system topology.
| Pattern | What it means | Why it may be used | Boundary |
|---|---|---|---|
| Sidecar | CEYO runs adjacent to an application or model-serving process. | Local evidentiary capture with clearer operational separation. | No modification of model weights by default. |
| Gateway | CEYO observes requests and responses at a controlled ingress or egress boundary. | Centralized control for multiple downstream systems. | Scope is limited to gateway-visible policy fields. |
| Wrapper | CEYO encapsulates a defined call boundary around an inference operation. | Cleaner instrumentation and tighter product-layer integration. | Still policy-scoped; not an open-ended telemetry feed. |
Core platform properties.
The CEYO platform is defined less by UI and more by control boundaries: what enters the record, who holds keys, what can be independently revalidated, and what remains outside the system’s claim surface.
Control surface
Capture is governed by explicit inclusion, exclusion, masking, and disclosure rules defined before artifact generation.
Deterministic serialization ensures independent parties can reproduce the exact byte path used for hashing.
Hashing and digital signatures transform the artifact into a tamper-evident record.
Reviewers can validate integrity and provenance without default access to weights or private implementation details.
Operating characteristics
Fail-open, non-custodial, policy-scoped.
The platform is intentionally structured to support oversight without becoming an uncontrolled monitoring plane or a mandatory operational choke point.
Availability by design
If sealing fails, inference continuity can remain independent while the event is logged or flagged for later review.
Artifact generation supports accountability workflows, but does not have to become the default execution gate unless an operator deliberately configures it that way.
Boundary declarations
CEYO does not make decisions, certify outcomes, or replace institutional review.
CEYO records only policy-scoped artifact content rather than acting as an unrestricted data collection layer.
Verification does not require default disclosure of model weights or trade-secret internals.
CEYO is record infrastructure attached to an inference boundary. It is not an AI platform, not a compliance determination engine, and not a substitute for operator governance, human authorization controls, or external adjudication.
The platform claim is narrower and stronger: produce integrity-sealed records that can be independently verified under declared policy scope.
