Summary

Ports the OpenAI API card's Live · Spend chart switch and the inspectable Tokens/min chart from upstream CodexBar v0.75.0 (steipete#4495, commit 5a40ac4: ProviderMenuChartContent.swift, MenuUsageBarStrip.swift, ProviderThroughputSection.swift). It reuses data the card already receives (throughput and openAiApiUsage on ProviderUsageSnapshot) and adds no new fetches or bridge commands. The change is frontend plus locale data: rust/src/locale.rs and the 10 .ftl files gain the new keys (the locale enum lives in the Rust crate, so this is not a frontend-only diff), but no Rust behavior changes.

  • Switch. OpenAILiveSpendChart replaces the plain Tokens/min grid on the card. The Live / Spend switch only appears when the snapshot has both a Tokens/min window and at least one day of OpenAI API usage history, as upstream does. Otherwise the card shows the Tokens/min grid exactly as before, and the per-day API chart stays out of a card that has no throughput.

  • Keyboard and screen readers. The switch is two plain toggle buttons with aria-pressed inside a labelled group: both stay in the tab order and activate with Space/Enter, so there is no radiogroup that would owe roving tabindex and arrow-key handling.

  • Default and persistence. Live is the default. The choice is stored per provider in localStorage["codexbar.providerMenuChartModes"] (a { providerId: mode } map, the same shape as upstream's providerMenuChartModes user default). A missing, unknown or malformed value falls back to Live.

  • Fixed height. Both layers stay mounted in one CSS grid cell. The inactive layer is visibility: hidden and aria-hidden, so switching modes does not resize the card or the tray panel. The hidden layer also drops out of hit testing and the tab order.

  • Spend layer. Title "Daily spend · Last N days" (N = historyDays). One bar per UTC day, scaled by costUsd.

  • Inspection. The new charts/ScrubBarStrip replaces the static SVG in both charts. Hovering or dragging (with pointer capture, so a drag keeps scrubbing past the edge) selects the bar under the pointer, and the selected bar gets an outline. A summary line under the chart shows that bar's details:

    • minute: 09:41 AM · 12K tokens · 4 requests, or 09:41 AM · reporting… for a pending minute
    • day: 2026-05-24: $3.75 · 712.5K tokens

    The line keeps its height while empty. The selection clears on pointer leave (unless dragging), on blur, on Escape, when a touch or pen lifts, and when a mouse drag is released outside the strip. When a refresh moves the selected minute out of the window, the selection is dropped. The selection is keyed by the bar's start time, so it stays on the same minute or day across refreshes. Keyboard: Left/Right/Home/End step through the bars.

  • The Settings > Providers > OpenAI > Live Usage chart gets the same inspection, because it uses the same component.

  • formatUsd / dayLabel move from OpenAIApiUsageChart.tsx into the new lib/openaiSpend.ts. Their behavior is unchanged.

  • Locale keys OpenAiChartModeLabel, OpenAiChartModeLive, OpenAiChartModeSpend, OpenAiTpmHoverMinute, OpenAiTpmReporting, OpenAiSpendChartTitle and OpenAiSpendHoverDay are added to all 10 .ftl files, locale.rs and keyGroups/core.ts.

  • The proof fixtures add openaiapi to the proof catalog (the same line as Add OpenAI Tokens/min tray metric #925, so the two PRs merge cleanly) and a synthetic openai-live-spend scenario: 60 minutes with the last two pending, and 30 days of spend.

Not ported: upstream's limit-line action hookup and the macOS menu highlight colors (no Windows equivalent). Upstream's limit line is already Live-only here, because it lives inside the Tokens/min layer, and the card passes no limits, as before.

Commands run

  • cargo fmt --all: clean
  • cargo clippy --manifest-path rust/Cargo.toml --all-targets -- -D warnings: clean
  • cargo clippy --manifest-path apps/desktop-tauri/src-tauri/Cargo.toml --all-targets -- -D warnings: clean. No shell behavior changed; the shell test suite was not rerun. The locale tests run in the frontend suite through the i18n harness, and the Rust placeholder-parity test passed in the crate suite on the same locale data in Add OpenAI Tokens/min tray metric #925.
  • pnpm test: 146 files, 1384 tests passed. Tests cover hover, drag past the edge, release inside vs. outside the strip, keyboard stepping, a selection dropped on refresh, the switch shown only when both charts have points, aria-pressed toggling on plain buttons, the default Live mode, persistence, and the unknown/malformed fallback.
  • pnpm run build: OK
  • pnpm proof:check (Chromium, mocked IPC): 13/13 passed
PASS  tray-default  (2 screenshots)

PASS  tray-openai-live-spend  (3 screenshots)
PASS  floatbar  (1 screenshot)

The tray-openai-live-spend scenario (Chromium, mocked IPC) runs these steps. The proof browser profile keeps localStorage between runs, so the scenario first clicks Live to start from a known mode instead of assuming the default:

  1. Opens the tray panel with the synthetic OpenAI API card, switches to Live, and checks that the Spend layer is aria-hidden.
  2. Moves and clicks the mouse on the Tokens/min chart, then checks that the summary reads "… tokens · … requests" and that one bar is selected.
  3. Clicks Spend and checks the "Daily spend · Last 30 days" title and the hidden Live layer.
  4. Inspects a day and checks that the summary contains ": $" and that one day bar is selected.

In the screenshots (tray-openai-live, tray-openai-live-inspect, tray-openai-spend-inspect), the panel height is the same in both modes.

Proof

This change only touches webview content (tray panel card content and locale strings): there are no window, chrome, tray icon or theme changes, so the browser proof above covers it under the repo's proof rules. Optional native follow-up on a fresh desktop build with a seeded OpenAI API snapshot: hover and drag the card chart in WebView2, and switch Live/Spend to confirm that the flyout height does not change.

Reference: upstream steipete/CodexBar steipete#4495 (read-only).

Summary by CodeRabbit

  • New Features

    • OpenAI API charts now offer Live and Spend views when throughput and spending history are available; your selection is remembered.
    • Hover, drag, or use the keyboard to inspect minute-level token and request details or daily spending and token totals.
    • Both views maintain a consistent card height.
  • Improvements

    • Pending throughput minutes are marked as reporting and excluded from rate calculations.
    • Chart controls and details are available in supported languages.

Full details: Provider Data Stays Siloed

Explanation

The pull request keeps provider data siloed. MenuCard passes the current provider.providerId, presence.openAiThroughput, and provider.openAiApiUsage to the OpenAI chart; describeCard still limits that throughput section to providerId === "openaiapi". openaiSpend.ts persists only the chart mode under a map keyed by the supplied provider ID, not identity, plan, account label, or email. The changed code adds no new specific-ProviderId branching in shared code. Existing provider-specific branches are unchanged.

Full details: Secrets Handled Safely

Explanation

The reviewed diff adds no token, cookie, API key, OAuth credential, or authorization header handling. The new UI displays usage counts and spend values, not authentication secrets. Searches of added code found no console/tracing/println logging, credential-like literals, snapshots, or credential-file changes. The only new persistence is the provider chart-mode map in localStorage, and no credential files or keyring entries are deleted or overwritten.

Full details: No Unapproved Dependencies

Explanation

The pull-request diff changes no Cargo.toml, package.json, npm/yarn lockfile, or pnpm packageManager setting. The changed-file inventory contains no dependency manifest or lockfile. Therefore, the check's failure condition does not apply.

Full details: Ui Changes Include Windows Proof

Explanation

The PR changes visible UI: MenuCard now renders OpenAILiveSpendChart, and the diff adds the Live/Spend switch and interactive chart layers. The PR adds a proof scenario with screenshot steps, and the supplied objectives report pnpm proof:check passed. However, the authored PR description is explicitly truncated before the command results, so the required statement that screenshots or proof came from a fresh Windows build cannot be verified.

Resolution

Provide the complete PR description, or confirm in the description that screenshots or the tray-openai-live-spend proof were captured from a fresh Windows build.

Keep selected-bar details readable.

When a selected-day summary exceeds the chart width, these rules replace the remaining text with an ellipsis. The spend chart provides no way to reveal that hidden text. Allow the summary to wrap so users can read the full selected-day details.
