Depth Bid Pressure

Raw events deliver ingredients. Etna Alpha labels the state. This deterministic fixture shows the strongest locally proven product shape: one immutable semantic core, one stable URI, an exact packet projection, and an explicit causal frontier.

State Receipt

What changed, why, and what remained unresolved.

The packet is the product. The receipt makes its semantic core legible without changing identity.

What changed

Balanced book → depth bid pressure

The fixture moved from balanced book context to depth bid pressure.

Why

Visible liquidity supported the transition

Visible-liquidity context supported the selected state before the causal cutoff.

Counterevidence

Forced-flow context stayed partial

Forced-flow context remained partial and its detailed observation arrived after the cutoff.

Unknown

No invented confirmation

The fixture does not establish what a complete forced-flow source would have shown at the cutoff.

Source votes

Support and partial context stay distinct.

Availability is not silently converted into agreement. Each source family keeps its own state.

Agent Lab

Measure reconstruction work, not prediction.

The same grounding question is traced against bounded raw observations and Etna Agent Context. This deterministic fixture does not execute a model.

Identity, citations, stale handling, causal cutoff, and replay remain explicit and read-only.

One object, many read-only surfaces

Carry the same identity forward.

These are local fixture routes. They prove frontend identity propagation, not current deployment parity.

Public boundary

Market context only. Read-only. Authority zero.

This fixture is not trading advice, a signal, an order instruction, raw feed resale, a profitability claim, or evidence of any private runtime outcome.

Deterministic public-safe fixture evidence. It demonstrates local product semantics and does not prove live, deployed, retained-real, commercial, or performance state.
