Etna Alpha · public market-state system

Hyperliquid emits events. Etna compiles them into state.

Exact, replayable market-state objects with source votes, causal time, evidence, memory, and read-only agent interfaces.

The packet is the product. StateCore is its immutable semantic truth layer—not a second packet, API, or execution spine.

Deterministic fixture State Receipt · not live

One state. One receipt. One identity.

Canonical state transition

See why the state changed—and what did not make the cut.

Raw feeds deliver ingredients. Etna Alpha labels the state while preserving contradiction, unavailable inputs, and causal time.

Knowledge Frontier

Only what was legally knowable enters Original-At-Time.

Later observations may appear in an additive Enriched-Now object. They never rewrite the original StateCore hash.

One object, many projections

Carry one exact identity across the public product.

Fixture identity is verified across these local projections. Production same-object activation remains held until a facade canary proves it.
