# ADR 0001: Treat LixelGO as unavailable

Status: accepted.

## Context

The actual stand consists of one K1, one MacBook and one ordinary TP-Link
Deco/mesh router. There is no phone, LixelGO reference session, Linux host,
dedicated capture router or public SDK.

The supplied design documents include several app-dependent experiments and
assume that provisioning payloads can be recovered by comparing LixelGO BLE
writes. That evidence source does not exist.

## Decision

- LixelGO is not a temporary dependency, broker or test oracle.
- App-dependent experiments remain only as historical reference.
- The active critical path is physical baseline, passive BLE, remembered Wi-Fi
  or device AP, evidence-led provisioning, application-session discovery, then
  stream capture and decoding.
- A fully opaque provisioning protocol with no evidence source is reported as a
  hard black-box blocker rather than approached with random writes.
- The existing router is used without changes for the first observation gate.

## Consequences

The project may reach a legitimate BLOCKED result before receiving live data.
This is still a successful pre-production conclusion because it identifies the
exact missing interface and prevents premature decoder work or risky device
mutation.
