Regional policy evaluation
Explore lightweight authorization and request transforms with versioned configuration and a defined fallback on stale or missing policy.

Regional request policies
Intelligence closer to the request.
Research into a lightweight regional boundary for authentication, request policies, selective caching, and routing to an origin gateway.
Research
The challenge
A clearer boundary. A better system.
Every request does not need every decision at the origin. But moving logic outward introduces new questions about configuration consistency, private data, and state ownership.
The approach
ASTER Edge
Edge explores a narrow regional layer: authenticate, validate, evaluate a versioned policy, then forward to the origin. Stateful decisions would stay with a clearly owned coordination layer.
Product direction
Designed around the decisions that matter.
Proposed capabilities guide the engineering work. Their implementation is a separate validation step.
Selective caching
Consider deterministic, explicitly cacheable operations. Sensitive or personalized inference responses require tenant-aware keys and an explicit retention policy.
Origin routing
Evaluate regional entry points without treating proximity as a guarantee of faster inference. Provider location and state access still shape the request path.

Engineering considerations
The tradeoffs belong in the design.
- Stateless versus stateful
- Validation can stay local; global quotas and coordination need a consistent owner. Replicating every decision increases complexity and failure modes.
- Configuration consistency
- Define propagation expectations, policy versions, and fail-open versus fail-closed behavior before introducing multiple regions.
- Runtime and security
- Measure startup and execution overhead against the actual workload. Keep secrets scoped and protect caches from cross-tenant disclosure.
Practical contexts
Where the architecture earns its place.
Public API boundaries
Reject malformed or unauthorized requests before forwarding them to the origin, with an auditable policy version.
Regional access strategies
Evaluate latency and data-handling constraints using controlled tests rather than assuming a global network solves both.
Development direction
Built in deliberate steps.
Research
An exploratory research direction, not an existing global network. Regional deployment, caching, and policy APIs remain proposed and require workload-specific validation.
- PHASE 01
Define the boundary
Separate local decisions from global state and document the threat model.
- PHASE 02
Compare deployment patterns
Measure a single origin against regional policy evaluation under controlled conditions.
- PHASE 03
Validate consistency
Test policy propagation, origin failures, tenant isolation, and rollback before expanding scope.
Proposed sequence. Milestones describe validation goals, not release commitments.
