Preserve reserved key7 while exposing physical wheel controls, complete consumer and numpad assignments, add sensor performance mode and 0 ms debounce, and couple normal/deep sleep timers with full read-back verification. Document packet layouts and hardware verification limits, format the family codecs and driver, and add optional lighting/sleep UI hints. Package checks and 2668 protocol tests pass; OpenMouse build, 405 tests and size check pass against the local package.

550-555: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winThe wired polling-rate rejection test does not test the model limit.
For every wired product,
unsupportedRateis16000.aj200pEncodeRate(16000)throws beforeupdateSettingsruns, so the check againstproduct.wiredRatesis never reached. The wired PAW3311 models (0xed03,0xed06) advertise onlyRATE_1K. A regression that lets them write 2000–8000 Hz would still pass this test. Use the first protocol rate that the connection does not support.♻️ Proposed change
- const unsupportedRate = product.wired - ? 16000 - : product.wirelessRates.includes(8000) - ? 16000 - : 8000; + const supportedRates = product.wired ? product.wiredRates : product.wirelessRates; + const unsupportedRate = + AJ200P_RATES.find((hz) => !supportedRates.includes(hz)) ?? 16000; await assert.rejects(client.setPollingRate(unsupportedRate));🤖 Prompt for AI Agents

Avoid rebuilding the complete DPI range on every call.
For PAW3955 profiles with 1-DPI steps up to 80,000, getDpiOptions() creates 80,000 entries each time it runs. Keep the complete writable range because validateDpi() accepts every in-step value. Do not replace it with a preset list. Cache the complete range or use a range-based consumer.

Adds WebHID configuration for the AJAZZ AJ200 / AJ200P AI family, which uses a separate protocol from the existing AJAZZ NJ07/NJ08 and GearHub drivers. The driver handles VID
0x363c, usage0xffa0:0x02, across 22 wired and receiver PIDs in the MC, PRO+, ULTRA, ULTRA+, MASTER and S ULTRA variants. The complete model/PID table and wire layouts are in docs/ajazz-aj200p.md.Packet layouts and model capabilities were derived from AJAZZ configurator 2.2.5 and sanitized configuration observations. Profile/rate actions are also supported by static analysis of the MASTER 3.3.13 action dispatcher. They are exposed with an experimental status note on other models/firmware; fixed-rate choices respect each model's advertised limits. Unknown ripple, BLE and flywheel settings, existing shortcut/macro entries and reserved bytes are retained. AI service features, receiver lighting, pairing, reset and firmware update are outside this PR.
The MASTER
0xed1c2.4 GHz receiver on Windows, mouse and receiver firmware 3.3.13, is hardware-verified.Summary by CodeRabbit
