…I evidence - Mouse PID set: drop 0x0807 (bundle X6 is 14457:4368 only; 2055 PIDs are keyboard-side) - Poll rate lives at reportUser (104) per vendor mO/pO/yO + Ar table, not reportUsb/reportEsb (0-7 receiver ranks); add wallhackBuildPollRateWrite + nearest-rank helper - DPI vendor limits 100-30000 (rh/ih); add constants - MIN_FIRMWARE: add keyboardBindings 57/40/53 gate from W7 - Battery (0xBA): vendor mouse port never sends it (auto-read = version/report_esb/dpi_rank/dpi8Block/combined/chipIds; O() has no BATTERY branch) — add wallhackBuildBatteryRead, mark decode best-effort, add readBattery() + fake-HID sniff script proving explicit-only flow - Debounce (area 109): address-known from He but absent from Ar/O()/auto-read/UI — mark experimental with range constants, keep raw R/W - Update hid.test.ts fixture to reportUser; add codec test
Vendor bundle never touches area 109 (absent from Ar/O()/auto-read/UI/demo); updater exe has no debounce strings either. Add safe read-only probe script and public readDebounceTime(); document hardware experiment (factory default first, then bounded default+-1 write probe with restore).

117-118: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAssert the debounce write address in the sniff script.
setDebounceTime()targets the documented area109, so this is a coverage gap in the sniff assertion, not evidence that the driver currently writes the wrong area. Record the decoded address and fail when no write targets109.Suggested fix
const seen: number[] = []; +const functionWriteAddresses: number[] = []; const store = new Map<number, number>(); ... const addr = packet[4]! | (packet[5]! << 8); + functionWriteAddresses.push(addr); const n = packet[3]!; ... -const debounceWrites = seen.filter((c) => c === WALLHACK_COMMAND.writeFunctionArea).length; +const debounceWrites = functionWriteAddresses.filter((addr) => addr === 109).length; console.log(`debounce write at area 109 issued (experimental path): ${debounceWrites > 0 ? "OK" : "FAIL"}`); await assertOk(batteryCount >= 1, "expected explicit BATTERY probe"); +await assertOk(debounceWrites >= 1, "expected write at address 109");🤖 Prompt for AI Agents

119-119: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAssert that
readBattery()sends its own command and returns a response.
readStatus()sends aBATTERYcommand before the direct read. The finalbatteryCount >= 1assertion can therefore pass ifreadBattery()sends no command. The script also only logsdirect, so it does not check the direct response.🐛 Suggested fix
+const batteryCountBeforeDirect = seen.filter((c) => c === WALLHACK_COMMAND.battery).length; const direct = await client.readBattery(); +const batteryCountAfterDirect = seen.filter((c) => c === WALLHACK_COMMAND.battery).length; ... -await assertOk(batteryCount >= 1, "expected explicit BATTERY probe"); +await assertOk(batteryCountAfterDirect > batteryCountBeforeDirect, "expected direct BATTERY probe"); +await assertOk(direct !== null, "expected direct BATTERY response");🤖 Prompt for AI Agents

it as fake-only: `makeFake` seeds area 109 with value 8, and
`WallhackMouseHidClient` reads that fake device rather than real hardware.

Do not describe the fake transport as a hardware probe.
The documented command always creates makeFake({ 109: 8 }), passes that device to WallhackMouseHidClient, and does not enumerate or connect to real hardware. It reports the seeded value 8 for area 109, not the mouse’s factory default. Add a hardware-backed mode, or mark the script as fake-only and remove the hardware instructions.
