Follow up to #1145. The X/Y link state of a Logitech slot was derived from X equal to Y when the rows were built. A row unlinked on purpose with equal values showed linked again after a refresh, because the mouse has no field for the link.

  • Unlinking or relinking a row is now remembered in the browser, per device and per onboard profile (localStorage key openmouse.dpi-unlinked, same pattern as the single DPI backup).
  • Rows with different X and Y are still unlinked, as before.
  • Replaces the in-session workaround from Restore X/Y DPI editing on Logitech slots #1145 with the stored state.

The state lives in that browser only; another browser shows linked rows until they are unlinked there. Typecheck and the 401 tests pass. No new test for the storage, and not yet tried on hardware.

Summary by CodeRabbit

  • New Features
    • Logitech DPI slot X/Y link settings are saved for each device and profile, and restored when you return to that setup.
    • Link changes apply immediately in the editor, and settings remain associated with the correct slots when rows are rebuilt or reordered.

📝 Walkthrough

The controller now persists DPI-slot unlink indices by active device and edited profile. The Logitech slot editor reads saved indices when it initializes rows, persists link toggles, and saves unlink state for enabled rows when it commits a slot plan.

Changes: DPI slot link state

Layer / File(s) Summary
Persist DPI-slot unlink state
src/device/controller.ts
The controller reads and writes sorted, deduplicated unlink indices in local storage, keyed by the active device and edited profile. Invalid or unreadable data produces an empty selection.
Apply persisted state in the slot editor
src/features/devices/cards/DpiCard.tsx
Row initialization reads saved unlink indices. Link toggles persist state immediately. Commits save unlink state for enabled rows at compacted positions. Row rebuilding no longer preserves prior local link flags, and the editor uses the unlink-state key as its React key.

Merge Risk: 🔵 Low · up to 7f866

A rare editing sequence may restore an unlink choice to the wrong slot, but normal persistence and identity isolation are otherwise guarded.

Security architecture risk: 🔵 Low · up to 7f866

The change remains limited to browser-local mouse preferences and preserves existing device-write controls. The main design risk is that saved slot positions can diverge from the device profile when staged edits are discarded or fail, causing linkage preferences to be restored onto the wrong rows.

Retained concerns

  • Low · reliability · inferred: Unlink metadata is persisted using compacted enabled-row positions before the device profile is committed. If an earlier row is removed and the staged profile edit is subsequently discarded or fails, the device can retain its original slot ordering while the browser retains the compacted indices. Refresh can then apply the preference to a different equal-valued slot. The new persistent state is outside the existing profile-edit rollback boundary.
Security review details

Security Blast Radius

  • observed — The new state belongs to the current browser origin and computed device/profile key. Bridge devices use a session key; native devices use vendor ID, product ID, and product name, so identical native devices can share preferences. This is preference ownership, not an independently enforced tenant or authorization boundary.

Security Findings and Attack Paths

  • inferred — An actor already able to modify this origin's localStorage can influence which equal-valued rows appear linked and therefore how later user edits couple X and Y. The stored indices do not supply hardware commands or create a new direct device-write path; no introduced security bypass was demonstrated in the inspected flow.

Trust Boundaries and Controls

  • observed — Device changes remain controller-mediated. Logitech slot application checks draft blocking, plan and limits availability, profile locking, enabled rows, and supported DPI values before staging the profile. Changing the computed device/profile key remounts the editor, whose cleanup clears its pending timer.

Hardening Proposals

  • proposed — Treat index remapping as part of the staged profile transaction: retain the prior mapping for discard and failed application, or reconcile metadata against the confirmed device plan before saving compacted positions.

Guard malformed DPI unlink storage on read and toggle.

The normal writer stores an object whose active entry is an array, so it does not create these malformed shapes from valid state. However, valid JSON such as null or an object with a non-array active entry can remain in localStorage after manual or external storage corruption. The Logitech editor can then throw during initRows(). The proposed unlinkedDpiSlots() guard prevents the render failure, but setDpiSlotUnlinked() also needs to validate the active entry before constructing the Set.

Proposed fix
 function unlinkedStore(): Record<string, number[]> {
   try {

Use the Bridge session key for DPI unlink persistence.

deviceStorageKey(activeDevice) omits the Bridge session identity, so identical Bridge devices share the DPI unlink entry. This can restore one device’s unlink choice on another device. Keep deviceStorageKey() unchanged because active-device preferences and Single-DPI backups use it.

The DPI unlink key is new in this PR, so no migration from an earlier DPI key is required.

Suggested fix
 function unlinkedKey(): string | null {
-  return activeDevice && editedProfile !== null ? `${deviceStorageKey(activeDevice)}#${editedProfile}` : null;
+  if (!activeDevice || editedProfile === null) return null;
+  const bridge = activeDevice as HIDDevice & { openMouseTransport?: string; key?: string };
+  const deviceKey = bridge.openMouseTransport === "bridge"
+    ? `bridge:${bridge.key ?? ""}`
+    : deviceStorageKey(activeDevice);
+  return `${deviceKey}#${editedProfile}`;

Remap unlink preferences when Logitech stages are compacted.

When an earlier Logitech stage is disabled, the enabled stages are compacted into new indices. setDpiSlotUnlinked stores the old raw index, while initRows reads that index from the compacted array. For example, an intentionally unlinked row at index 1 can move to index 0 and restore as linked after reinitialization.

Remap each saved preference to the surviving row’s new index during the Logitech commit.

Suggested fix
     if (mode === "logitech") {
+      const enabledIndices = next
+        .map((row, index) => row.enabled ? index : -1)
+        .filter((index) => index >= 0);
+      const unlinked = control.unlinkedDpiSlots();
+      unlinked.forEach((index) => control.setDpiSlotUnlinked(index, false));

Remount DpiStageEditor when the device or profile identity changes.

When a Logitech device or onboard profile changes without changing the stage X/Y values, DpiCard keeps the same key="dpi" and DpiStageEditor keeps its local rows because sourceSig excludes identity. The old linked flags can therefore remain visible instead of the new identity's state from control.unlinkedDpiSlots().

Suggested fix
 export function DpiCard({ snapshot }: { snapshot: ControlSnapshot }): ReactNode {
   // A table with one value in every stage is what Single saved, so reopen in that view.
   const [editorView, setEditorView] = useState<"stage" | "single">(() => (
     singleFillsStageTable(snapshot) && isUniform(snapshot.deviceStatus?.dpiStages) ? "single" : "stage"
   ));

Persist unlink state from the current row state.

commit stores compacted indices, then treats them as indices into next. If next still contains disabled rows, a later commit can move an unlink preference to the wrong slot or discard it. Build the replacement list from enabled rows whose linked flag is false, and persist that list in one replacement operation.

Update the unlink-state persistence in commit to derive the replacement list
from enabled rows in next whose linked flag is false, then persist that list
with one replacement operation instead of translating compacted indices through
next. Preserve the unlink state associated with each current row.

The link state was derived from X equal to Y, so a row unlinked on purpose with equal values showed linked again after a reload. Remember unlinked rows in the browser per device and profile.

Closing in favour of #1177, which already includes this change (an unlinked Logitech X/Y slot stays unlinked after a refresh) together with the custom games and game profile work that builds on it.
