+# Wave 1 Baseline Snapshot
+
+Generated: 2026-02-28
+
+## Hardware Access Baseline
+- Available hardware lines: JP108 + Ultimate2.
+- Exact attached PID variants: pending local identify run on connected hardware.
+- Temporary lab fixture defaults remain:
+  - JP108: `0x5209`
+  - Ultimate2: `0x6012`
+
+## Required Next Verification Step
+Run identify flow with connected hardware and confirm fixture PIDs:
+1. `cargo test --workspace --test hardware_smoke -- --ignored --exact hardware_smoke_detect_devices`
+2. `./scripts/run_hardware_smoke.sh` with `BITDO_REQUIRED_SUITE=108jp`
+3. `./scripts/run_hardware_smoke.sh` with `BITDO_REQUIRED_SUITE=ultimate2`
+
+If detected variants differ, update `harness/lab/device_lab.yaml` fixture PIDs immediately.
+
+## Support Baseline
+- Existing `full` paths: JP108/Ultimate2 and previously confirmed families.
+- New expansion wave devices remain `candidate-readonly` (detect/diag only).
+- No new firmware/write enablement for no-hardware targets.
