App side of the Endgame OP1/XM2 rollout.

  • Regenerated mirror (node scripts/sync-supported-devices.mjs): 14 Endgame rows with pinned PIDs (entire OP1 + XM2 series incl. wireless, plus XM1r). This also pulls in unrelated upstream drift (Logitech/Redragon/ATK/WLMouse rows) — legitimate sync, not hand edits.
  • Noir fallout fixed: the regen exposed that upstream moved PID 0x2255 to K-snake X11 and deleted the NOIR E1 row. The two crosscheck tests now assert the new name-based reality instead of the stale PID rows.
  • egg-ot UI parity: egg-ot family traits, preview mode, OP1 RGB fixture + test.

No new protocol imports, so this builds against the published package. Merge after OpenMouse-Project/mouse-protocol#199 (driver) and openmouse-landing-page#47 (table source).

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

The pull request revises supported-device records across several brands and adds an Endgame Gear OP1 RGB preview mode with a fixture and eggFamily trait mapping.

Changes

Supported-device catalog

Layer / File(s) Summary
Catalog records and cross-checks
src/supported-devices-data.ts, src/supported-devices-crosscheck.test.ts
The supported-device table gains and removes entries, and updates product IDs and statuses across several brands. Cross-check tests now expect a name match for M2-NEX without a product ID and no NOIR E1 match.

Endgame Gear OP1 RGB preview

Layer / File(s) Summary
Preview mode, fixture, and trait
src/preview-modes.ts, src/preview-fixtures.ts, src/device/traits.ts, src/preview-fixtures.test.ts
The preview parser accepts egg-ot and maps it to an OP1 RGB fixture. The fixture includes wired status and display settings. The egg-ot family mapping enables eggFamily, and tests check the fixture’s identity and capability values.

Merge Risk | 🔵 Low · up to cc7e1

Merge Risk: 🔵 Low · up to cc7e1

A Noir Gear device reporting PID 0x2255 can be incorrectly listed as a supported K-snake device in a hardware-test report. Correct the match and retain reported-PID regression coverage; the remaining risk is localized.

Security Architecture Review

Security architecture risk: 🔵 Low · up to cc7e1

The catalog and preview changes preserve the existing separation between displayed device information and hardware permissions. No introduced security issue was established, but compatibility with the coordinated driver rollout has not been independently verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated exposure is limited to browser preview state and supported-page report attribution. Inspected consumers do not propagate catalog support status into hardware authorization or driver-selection authority.

Security Findings and Attack Paths

  • observed — The existing matcher accepts a PID match without rejecting a different brand, so revised rows can change report attribution for reused PIDs. This rule predates the PR, and the inspected outcome is supported-page report metadata rather than a hardware permission or command capability.

Trust Boundaries and Controls

  • observed — The attacker-influenced preview query crosses an explicit build gate and literal allowlist before fixture lookup. An ordinary egg-ot preview creates no active hardware client, and preview startup suppresses automatic HID reconnect and connection listeners.

Resilience and Maintainability Implications

  • observed — Hardware activation serializes switches and clears prior status before replacement; failed activation and disconnect recovery clear active authority and pending state. These lifecycle paths are unchanged by the PR.
  • inferred — Fixture status is shared by reference with controller state, but inspected staged edits clone status and no mutation leak was demonstrated. The aliasing pattern and uncaught startup import rejection predate this PR; behavior of external fixture consumers remains unknown.

Keep a 0x2255 regression case for both Noir Gear devices.

The revised null inputs test only name fallback. They do not test a Noir Gear device that reports PID 0x2255.

crosscheckSupportedDevices uses only productId in the PID branch. It uses brand only for ranking and does not reject a mismatched brand. The updated catalog leaves 0x2255 only on supported K-snake X11, so either Noir Gear device can be reported as supported K-snake X11 in the hardware-test report.

When the device brand is present, filter PID candidates to the same brand before accepting a row. Preserve shared-PID matching for compatible brands, then retain the name fallback.
