The Yiciyuan FJB-01 / FJB-02 (役次元) are JieLi-SoC BLE strokers advertising as "YCY-FJB-01" and "YCY-FJB-02" with three independent actuators: - stroke axis (linear oscillation) - vibe axis (vibration motor) - axis_c (third haptic motor driven in app-recorded patterns) Each axis takes an unsigned 0..=0x14 level; the 16-byte control packet is sent to characteristic ff41 under service ff40 as: [0x35, 0x12, stroke, vibe, axis_c, 0x00 x11] Battery push arrives on the same notify characteristic as a `35 13 01 <pct>` frame mixed with 10Hz uptime ticks (`35 14 ..`); the handler filters by prefix. FJB-01 is verified against physical hardware. FJB-02 is its successor in the same product line; the official app routes both through an identical code path (same vuex state, same hex-stringed motor frame, same BLE service/characteristic UUIDs), so the same protocol module covers it. Hardware verification welcome. Adds: * buttplug_server_device_config/device-config/protocols/yiciyuan.yml * buttplug_server/src/device/protocol_impl/yiciyuan.rs * tests/.../test_yiciyuan_protocol.yaml (FJB-01) * tests/.../test_yiciyuan_protocol_fjb02.yaml (FJB-02) * regenerated buttplug-device-config-v5.json (version 5.6) Test commands gated on protocol v3+ since v0-v2 single-axis Vibrate semantics don't map cleanly to a multi-actuator device. All 828 device protocol tests pass on debug build.

Closes #887. Supersedes #901 (which I closed to tidy up); the product-link and oscillate-vs-vibrate questions from that thread are addressed below.
Adds device support for the Yiciyuan (役次元) YCY-FJB-01 stroker (and its identical-protocol sibling FJB-02), built on a JieLi SoC. Protocol was reverse-engineered independently and verified against hardware reporting firmware
02 07 07. This addresses the vendor left unsupported when #688 was closed for inactivity, answering each of that reviewer's open questions (oscillate vs vibrate, product link, full test coverage).Device
