… the workspace Two follow-ups from the superset-sh#5337 review. Restored route wasn't org-scoped. The cause was one step earlier than it looked: router history lives in localStorage under a single "router-history" key, and localStorage is shared by every window of the profile. All windows read and wrote one history, so the last window to navigate decided where every window reopened — routinely onto another window's workspace, in another organization. History is now keyed by the window's persisted key, which the renderer receives synchronously as a process argument (the router restores before React mounts, so it cannot wait on IPC). The unkeyed record is left in place as the fallback, which is what lets an existing single-window profile keep its history. Closed windows would otherwise strand their history on a store with one ~10 MB quota for the whole profile, so a boot sweep drops records whose window is no longer in the registry. window.liveKeys exposes that set. Same-org windows shared a title. Several windows on one org is a normal way to work and they were indistinguishable in the macOS Window menu, so the title now leads with the workspace the window is on and keeps the org behind it.
…e ids Follows up the superset-sh#5337 merge decision. Dropping the per-window pane-key prefix was right — the browser bridge addresses panes by bare paneId — but the safety argument behind it doesn't hold on its own: BrowserManager still keys `panes` by bare paneId (workspaceId rides inside the value, it is not part of the key), and the tabs fallback let EVERY window with no record of its own read the same legacy tabsState. Two such windows therefore hold identical pane ids, and the second register() replaces the first window's mapping and tears down its listeners. Pane ids are unique per mint, so the only way to duplicate one is two windows reading a single stored record. Now only the window restored from the pre-multi-window record inherits it — an existing user's tabs still survive the upgrade — and every other window starts with its own empty layout instead of a copy.
…rits it The scoped-key fallback never fired. `createPlatformWindow` mints a key for every window (`key ?? randomUUID()`), so `window.App.windowKey` is always set in production and the bare "router-history" record written by a pre-multi-window profile was simply never read again — an upgrading user silently lost their route and reopened on "/". The comment claiming the fallback preserved that history was wrong. Replace it with a one-time handoff to LEGACY_WINDOW_KEY, the key the first restored window already adopts for its tab layout. Same window, same upgrade story, one concept instead of two. The record is moved rather than copied: leaving it behind would strand a key nothing reads and the boot sweep deliberately never collects. LEGACY_WINDOW_KEY moves to shared/ because the renderer now needs it too, and has to make this decision synchronously — the history is restored at module evaluation, before React mounts, and all IPC is async. The resolution is a pure function over a storage interface, so the upgrade path is tested directly rather than through the module-level singleton.

…alStorage localStorage is one ~10 MB quota shared by every window of the profile and by every TanStack DB collection in it, and the per-window keys superset-sh#6775 introduced are entity-scoped with a key minted per window. `apps/desktop/AGENTS.md` asks for a bound, a deletion path, and a retirement plan; the boot sweep answered all three across launches but not within one, and it was best-effort. The history now lives in app-state.json as `routerHistoryByWindow`, beside `tabsStateByWindow` and keyed the same way. That gets it the bound the sweep couldn't: `pruneWindowScopedState` already runs from the same place that writes the restorable window set, so a window's history is dropped when its window stops being restorable, on every persist rather than at the next boot. The issue proposed host-side SQLite. This uses app-state instead. `local-db` is the *host service's* database and a host can be remote, so a window's route would have followed the project to another machine; and app-state already has the per-window keying, the pruning and the legacy-inheritance rules this needs, so a second mechanism would have had to reimplement all three. Reads stay synchronous. The router is built from the history at module evaluation, before React mounts, and every path through electronTrpc is async, so the main process hands the record to the renderer on its command line alongside the window key it already passes. Writes are async and fire-and-forget. The payload is trimmed from the oldest entry until it fits a byte budget, because Windows caps a command line at 32767 characters and a history of long paths can be large while well under the entry cap. Existing profiles are migrated on first read: the window claims its own record and removes it, and only the window that inherits pre-multi-window state may claim the shared one. `router-history` moves to `DEAD_KEYS` for the profiles whose owning window never opens again, and the sweep and the `window.liveKeys` route that fed it are deleted. Closes superset-sh#6795.

Two review findings on the handoff. Trimming to the argv budget always dropped from the front, on the assumption that the oldest entry is the furthest from where the window is. That is false when the window sits at index 0 with forward history: the first entry *is* the active one, so a window with a long forward stack came back on a route it had navigated away from rather than its own. Give up whichever end is further from the index instead, so the active entry is the last thing lost. The existing test only covered a window at the newest entry, which is why it passed. `isValid` also accepted a fractional index, and `entries[0.5]` is undefined — the router would start on no route at all. Reachable from a hand-edited profile through the migration path, so require an integer.
`useMatchRoute` without `fuzzy` matches only the route itself, so the title would fall back to the organization the moment the workspace route gains a child. It has none beyond its index today, so this changes nothing yet — but the failure would be silent, and the intended meaning is "this window is on a workspace", which is fuzzy by nature. Raised by CodeRabbit on superset-sh#6917, which carries this file through its stack.

Problem
Renderer localStorage is one ~10 MB quota shared by every window of the profile and by every TanStack DB collection in it. The per-window history keys #6775 introduced are entity-scoped with a key minted per window, which is the shape
apps/desktop/AGENTS.mdasks to keep out of it.The boot sweep answered the three questions across launches, but not within one: windows opened and closed during a long session accumulated records until the next boot, and the sweep was fire-and-forget.
What changed
The history moves to
app-state.jsonasrouterHistoryByWindow, besidetabsStateByWindowand keyed the same way.That gets it the bound the sweep couldn't.
pruneWindowScopedStatealready runs from the same place that writes the restorable window set — "so the two cannot drift", per its own comment — so a window's history is dropped when its window stops being restorable, on every persist rather than at the next boot.Why not
local-db, as #6795 proposedI wrote that issue and I think it named the wrong store.
@superset/local-dbis the host service's database, and a host can be remote. Per-window router history is desktop UI state about a window on this machine; putting it there would have sent it to whichever machine the host runs on and made a local window's route depend on a remote round-trip.app-state.jsonalready has the per-window keying, the pruning pass, and the pre-multi-window inheritance rule that this needs. Alocal-dbtable would have had to reimplement all three, and gained nothing.Reads stay synchronous
persistentHistoryis a module-levelconst: the router is built from the history before React mounts, and every path throughelectronTrpcis async. So the main process hands the record over on the command line alongside the window key it already passes, and only writes go over IPC.buildRouterHistoryArgtrims from the oldest entry until the payload fits a byte budget — Windows caps a whole command line at 32767 characters, and a history of long paths can be large while well under the entry cap. The entry the window is actually on is the last thing given up.Migration
router-history:<key>record and removes it.LEGACY_WINDOW_KEYmay claim the barerouter-historyrecord, so no window adopts a route from another window — possibly in another organization.sweepDeadPersistedKeys()inrenderer/index.tsx: imports are evaluated before the statements that follow them, so the read always wins the race with the sweep.router-historymoves toDEAD_KEYS(prefix match, covering both shapes) for profiles whose owning window never opens again, and the registry entry is removed since nothing writes those keys now.sweepDeadWindowHistoriesand thewindow.liveKeysroute that existed only to feed it are deleted.Testing
historyStore.test.ts— 15 tests: handoff parsing including malformed payloads and out-of-range indexes, the migration rules (own record, legacy claim, ordinary window refused, corrupt record, throwing storage), and the entry cap.routerHistoryArg.test.ts— 6 tests: round-trip, argv-hostile characters, trimming to the budget while keeping the current entry, and refusing to emit an oversized argument.pruneWindowScopedState.test.tsnow imports the realpruneByWindowinstead of reimplementing the rule, and covers the identity-preservation behaviour that keeps an unchanged map from marking app-state dirty.persistent-hash-history.test.tswrite assertions now go through a mocked tRPC client rather than reading localStorage, so they exercise the real path.bun testinapps/desktop: 2954 pass, 0 fail. Typecheck clean apart from the pre-existing duplicate-dependency errors onmain(@types/hast,mermaid,@codemirror/view).Summary by cubic
Moves per-window router history out of renderer localStorage into
app-state.jsonasrouterHistoryByWindow, pruned with the restorable window set on every persist instead of accumulating until the next boot. Reads stay synchronous: the main process hands the saved history to a new window as a command-line argument, because the router is built before React mounts and IPC is async.Uses
app-state.jsonrather than@superset/local-dbas the linked issue proposed: that is the host service's database, hosts can be remote, and app-state already has the per-window keying, pruning, and legacy-inheritance rules this needs. When trimming history to the command-line byte budget, it drops from whichever end is furthest from the active entry, so a window never restores onto a route it had navigated away from.Migration
router-history:<key>record and removes it.LEGACY_WINDOW_KEYmay claim the barerouter-historyrecord, so a window never adopts another window's route.DEAD_KEYSfor profiles whose owning window never opens again.Only the legacy window now inherits the pre-multi-window
tabsState; every other window starts empty, which stops duplicate pane ids from making one window'sregister()tear down another's listeners. Window titles now lead with the workspace name (then the org) via a fuzzy route match, so windows on the same org are distinguishable and the name survives nested workspace routes.Written for commit dfb44ce. Summary will update on new commits.
