fix(desktop): keep usage meters in sync across windows - #1227
Merged
Conversation
Problem: two desktop windows on one machine showed different Claude/Codex usage meters in the header and the usage popover. One window stayed current and the other lagged. Cause: the brain built one usage tracker per project scope, so two windows on two projects were fed by two pollers with different phases. A window with no project binding read a dormant in-process tracker that stops whenever a project is open, so it froze at the disk cache. The renderer ordered snapshots by wall-clock lastPolledAt across producers with unrelated clocks, so a window could latch ahead and reject real pushes. Lazy preload rebinds never notified the renderer. Change: one machine-scoped tracker shared by every brain project scope. Unbound windows proxy reads to the brain and receive its updates through a single main-process broadcast. Every snapshot carries a producer revision and the renderer orders by it. Binding changes always reach the renderer. The usage hook re-reads the cached snapshot on window focus and visibility. Runtime event subscriptions survive a throttled pump. Verification: desktop usage/ipc/preload/adeActions vitest files 759 passed; ade-cli scope/rpc/sync files 347 passed; both typechecks clean. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Keep quality follow-ups that stop unbound Settings from borrowing another project's stats, keep production from starting a second usage poller, and reject untyped account rollups. Co-authored-by: Cursor <cursoragent@cursor.com>

📝 WalkthroughWalkthroughUsage tracking now uses one machine-level poller with project-specific scopes. Desktop IPC bridges usage reads and events through booted runtime scopes. Snapshot revisions provide ordering across producers, while preload binding updates and renderer wake handling are deduplicated. ChangesShared usage tracking and synchronization

nextProjectCostsByRoot so every requested root is represented, including roots
omitted by the scan or by a worker result lacking projectCostsByRoot. After
processing scannedProjectCostsByRoot, add missing requested roots using their
cached values when available, marking them as scanned without triggering
repeated full refreshes; preserve carryForward for roots the scan reported.

- Line 76: Update the revision ordering logic around nextRevision and
currentRevision so a stamped next snapshot is accepted over an unstamped current
snapshot, while an unstamped next snapshot is rejected when currentRevision
exists; preserve existing ordering behavior for other revision combinations and
update the legacy-cache test to cover this case.

Problem
Two ADE desktop windows on the same machine could show different Claude/Codex usage meters, so the header and Settings looked like they were tracking different accounts.
Cause
Each open project booted its own usage poller. Unbound windows (Welcome, Hub) either sat on a dormant tracker or borrowed another project's stats. Renderers ordered snapshots by wall-clock lastPolledAt, so a slower producer could latch stale numbers. Production mobile-sync context init could also start a second poller and broadcast onto the same channel as the brain.
Change and boundary
One machine-scoped tracker (attachSharedUsageTrackingScope) publishes UsageSnapshot.revision. Unbound windows proxy machine/account reads to a booted brain scope and receive ade.usage.event; project-scoped Settings reads stay on the dormant tracker so Welcome cannot show another repo as This project. Production no longer starts or broadcasts a second in-process poller. Account rollups reject untyped payloads. Idle event-subscription expiry is 180s. CLI ade usage, the TUI usage pane, and iOS quota snapshots are additive (revision is ignored on mobile). Hosted web still consumes the untyped quota JSON. No SDK mirror.
Verification
Authored with Cursor Grok 4.6 via ADE (quality/test/ship); original meter-sync fix by Claude Fable 5.1 / Claude Opus 5.
Note
Medium Risk
Touches usage polling, IPC routing, and cross-process account rollup writes; mistakes could show wrong scope stats or stale meters, but behavior is heavily tested and fallbacks to dormant/cached trackers remain.
Overview
Fixes two windows on one machine showing different Claude/Codex meters by making provider quota a single machine-level poller and giving every consumer the same snapshot stream.
The brain/CLI now
attachSharedUsageTrackingScopeso multiple project runtimes share one tracker: one poll timer, onelastSnapshot, and per-scope inputs (DB,projectRoot, GitHub, analytics). Ledger scans run once and returnprojectCostsByRootfor each attached repo. Snapshots get arevision(producerId+seq) and a singlepublishSnapshotpath so no caller gets a fresher copy than subscribers.Desktop main subscribes to the brain’s runtime usage events and
broadcastsIPC.usageEventfor unbound windows (Welcome/Hub). IPCcallBootedUsageAction(viabootedUsageScopeRoot) serves machine-scoped reads from any booted project; project-scoped stats still use the dormant tracker so another repo is never shown as “this project.” Desktop fans out account rollups and pushesusage.applyAccountRollupsinto the brain, with validation for malformed RPC payloads.Renderer/preload: snapshot ordering uses
shouldApplyUsageSnapshot(revision-based, notlastPolledAtalone); preload publishes project binding changes when it rebinds locally; usage UI re-reads on visibility/focus after background throttling. Runtime event subscription idle expiry moves to 180s so minute-throttled background pumps are not torn down early.Production desktop only starts the in-process usage poller in the in-process runtime path, avoiding a second broadcaster on the brain channel.
