Summary by CodeRabbit

  • New Features
    • Added quota status visibility for combo targets, including exhausted-provider badges.
    • Added alerts when all targets in a combo have exhausted quota.
    • Combo overview attention indicators now include quota-related warnings.
    • Quota information is refreshed while the Combos page is active.
  • Localization
    • Added translated quota-exhaustion messages in English, German, Japanese, Korean, Russian, Turkish, Simplified Chinese, and Traditional Chinese.
  • Style
    • Added light and dark theme styling for quota badges and exhaustion alerts.

Show quota-exhausted indicators on combo target rows when a backing
provider has 0 remaining credits. An attention banner appears in the
combo detail panel when every target is exhausted, warning that requests
will fail closed.

Changes:
- combo-workspace-data.ts: add exhaustedProvidersFromQuotaReports(),
  isProviderExhausted(), and 'all-targets-exhausted' attention type
- combo-workspace-controls.tsx: render a '0 credits' badge on exhausted
  target rows
- combo-workspace-detail-panel.tsx: show a warning banner when all
  targets are exhausted
- combo-workspace-overview-panel.tsx: surface all-targets-exhausted in
  the attention list
- Combos.tsx: fetch /api/provider-quotas and derive exhausted providers
- i18n: add quota-exhaustion keys across all 8 locales
- styles-combos-workspace.css: quota badge and exhausted banner styles

Closes #1702

Combo quota exhaustion

Layer / File(s) Summary
Quota detection and attention contract
gui/src/combo-workspace-data.ts, gui/src/pages/Combos.tsx
Quota reports now produce a set of exhausted providers. Combo attention can report all-targets-exhausted.
Exhaustion state propagation
gui/src/combo-workspace-types.ts, gui/src/components/ComboWorkspace.tsx
exhaustedProviders flows from Combos to overview and detail panels.
Quota-aware combo and target UI
gui/src/components/combo-workspace-overview-panel.tsx, gui/src/components/combo-workspace-detail-panel.tsx, gui/src/components/combo-workspace-controls.tsx
The UI marks exhausted targets and displays alerts when all configured targets are exhausted.
Localized presentation
gui/src/i18n/*.ts, gui/src/styles-combos-workspace.css
Translations, target badges, and exhaustion banners support the new quota states.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to c8c43

The PR adds per-target quota indicators, but quota badges may be missed when provider names contain whitespace and may remain incorrectly marked exhausted after a refresh failure or panel deactivation. The change is mergeable with explicit owner follow-up to normalize identifiers and clear stale state.

P2 Badge Include percentage windows in quota exhaustion detection

The management API represents exhaustion for Codex, Anthropic, OpenRouter, and most other supported providers through fiveHourPercent, weeklyPercent, monthlyPercent, customWindows, or pool aggregation data; creditsUsd is currently emitted only by the A6API probe. Consequently, a provider whose reported limit is fully consumed is omitted from this set, so the new target badge, banner, and overview warning do not appear for nearly all quota-reporting providers. Derive exhaustion from the complete, aggregation-aware quota shape rather than requiring creditsUsd.

P2 Badge Ignore disabled targets when computing total exhaustion

When a combo contains an enabled exhausted provider plus a disabled provider, this every check returns false because /api/provider-quotas intentionally omits disabled providers. Runtime selection in src/combos/resolve.ts skips that disabled target, so every target that can actually receive a request is exhausted even though the overview does not warn; the mirrored calculation in DetailPanel has the same problem. Compute total exhaustion over enabled/routable targets using the provider configuration supplied to the workspace.

P1 Badge Document the new combo quota indicators

This introduces visible target badges, an alert banner, and a new overview attention state, but the commit contains no docs-site/ update. Add the indicator semantics and limitations to the existing combo dashboard documentation so users know what data drives the warning and when it refreshes.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Canonicalize provider identifiers before storing them.

Line 408 stores report.provider without normalization. Lines 236 and 419 query trimmed provider names. If the API returns "provider-a " and a combo target contains "provider-a", the quota badge and attention item do not render.

Trim the report provider name and skip empty identifiers before adding it to exhausted.

Proposed fix
   for (const report of reports) {
+    const provider = report.provider.trim();
+    if (!provider) continue;
     const q = report.quota;
     if (!q) continue;
     const credits = q.creditsUsd;
     if (!credits) continue;
     if (credits.unlimited) continue;
     if (typeof credits.remaining === "number" && credits.remaining <= 0) {
-      exhausted.add(report.provider);
+      exhausted.add(provider);
     }
   }

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Clear stale quota state when the quota refresh has no current result.

Line 223 ignores failures without clearing exhaustedProviders. Line 213 also returns while retaining prior state. If a provider recovers after an earlier exhausted report and a later refresh fails, the overview and detail panels continue to show the exhausted status as current.

Clear the set when a new quota request starts, when the panel becomes inactive, and when a non-cancelled request fails. Alternatively, retain a freshness state and suppress quota UI until the next successful response.

Proposed fix
   useEffect(() => {
-    if (!active) return;
+    if (!active) {
+      setExhaustedProviders(new Set());
+      return;

Triage note (2026-08-15): keeping this as draft. The GUI surfacing for #1702 is on track, but the head is gate-blocked: hygiene + enforce-target fail (missing regression test, missing UI screenshot), and 5 review threads are still open (including the disabled-targets counting nit and provider-name canonicalization). Needed before merge: a screenshot in the description, one focused unit test (e.g. exhaustedProvidersFromQuotaReports / buildComboAttention), and resolution of the open threads.
