fix(web): offer hub limits from the model usage popup - #30896
Fixes#30886. A Claude connection through CLIProxyAPI shows "Unavailable" in the model usage popup even when the same environment has usable hub quotas in Usage and /usage-limits.
selected account has no usable limits
- Limits: Unavailable+ same-provider hub has usable limits → View hub limits → existing in-chat usage report+ otherwise → Limits: Unavailable
The popup keeps valid selected-account quotas. It does not guess which hub account serves the endpoint or present a pool's allowance as that account's quota. This is a focused fix for the misleading unavailable state using the existing report, with no routing, quota-fetching, or contract changes. Web and desktop share this popup; mobile has separate UI and is unchanged.
Evidence
Synthetic Claude custom-endpoint fixture with a usable Claude hub account, rendered in headless Chromium at the same 280px width in dark mode.
Before
After
Before: pnpm exec vp test run apps/web/src/components/chat/ThreadDetailsUsage.browser.test.tsx fails because the popup renders Unavailable instead of offering the hub report.
After: the same test passes. It checks the action, excludes unrelated-provider and failed hub readings, and preserves valid selected-account quota bars.
pnpm exec vp run check:changed passes format, lint, knip, affected-package typechecking, nearby tests, and React compiler checks. Nearby tests: 50 passed across 4 files.
Full-app visual verification was attempted with an isolated dev server, but T3's browser automation timed out taking a snapshot. The images above are actual component renders with synthetic data, not captures from a live proxy connection. Live CLIProxyAPI routing was not tested.
Merge Danger
Door: two-way. Reverting restores the original unavailable row.
Blast Radius: small. Only the web/desktop thread-details usage row and its existing in-chat report action change.
Macroscope's review found this PR approvable — Adds a “View hub limits” link when provider-specific usage limits are unavailable. It reuses the existing panel without changing quotas, permissions or product defaults.

Walkthrough
The model details usage panel can link to hub limits when selected endpoint limits are absent or unavailable. ChatView passes the usage-limits handler to the panel. Browser tests cover matching hub accounts, unavailable cases, and endpoint limits.
Changes: Hub usage limits
Layer / File(s)
Summary
Usage limits display and wiring apps/web/src/components/chat/ThreadDetailsUsage.tsx, apps/web/src/components/ChatView.tsx, apps/web/src/components/chat/ThreadDetailsUsage.browser.test.tsx
The usage panel checks selected-instance limits and matching source-account limits. When valid hub limits exist and selected limits are absent or have a notice, it shows a “View hub limits” button if the callback is available. ChatView passes the handler, and browser tests cover hub and endpoint limit states.
The model usage popup now offers a "View hub limits" action only where the usage report can be displayed. Selected-account quotas continue to show as before. No merge-blocking risk remains.

Explanation
The title "fix(web): offer hub limits from the model usage popup" matches the main change. The PR adds a "View hub limits" action to the model usage popup when the selected account has no usable limits but a same-provider hub has usable limits. The title is concise and uses a conventional commit format.
Full details: Description check
Explanation
The description follows the template well. It has a Summary that states the problem (Claude via CLIProxyAPI shows "Unavailable" despite usable hub quotas) and the change (View hub limits action). It includes verification steps with test commands and observed results, before/after screenshots, and a note on what was not tested (live CLIProxyAPI routing, full-app visual verification). It links the issue (#30886). The template's Problem, Change, Scope, and Verification headings are not used verbatim, but the required information is present. The Scope section does not explicitly say why a bug fix is needed without a separate issue, though it does link #30886. The agent/model attribution line is missing.

Explanation
[#30886] The whole-PR diff against the merge base changes apps/web/src/components/chat/ThreadDetailsUsage.tsx. The component still reads the selected instance's limits from the usage report or the provider snapshot. It sets hasHubLimits when any source account has the selected provider's driver and no limits notice. When selected limits are absent or carry a notice, and hub limits exist, it renders a "View hub limits" button wired to onOpenUsageLimits. The component returns null only when neither source is usable. Pooled hub windows are not rendered as selected-account windows, so the popup does not attribute pooled quota to one routed account. This meets the #30886 objectives: an actionable path to the pooled readings, and no change to routing or quota fetching. The head diff for this file matches the previous assessment. The browser test was not re-run in this review. The code evidence supports compliance. Live CLIProxyAPI routing and real subscription accounts are not verified, as the PR states.
Full details: Out of Scope Changes check
Explanation
The whole-PR changes cover three areas. ChatView.tsx adds one prop wiring line that passes the usage-limits opener. ThreadDetailsUsage.tsx adds the onOpenUsageLimits prop, the hub-limits check, and the action row, and imports the existing Button component. The browser test covers this behavior. Each change connects to the #30886 popup fix. The head diff shows no changes to routing, quota fetching, shared contracts, or mobile code. The new required prop on ThreadDetailsUsageInput is the intended interface change for the action.

Configure a custom Claude endpoint and a same-provider synthetic hub source. Confirm Usage → Limits and /usage-limits show 75% session and 60% weekly remaining. Enable Usage limits and open thread details. Base shows “Unavailable”; head offers “View hub limits”. Click it on head to open the existing report.
Both sides: Chromium 156 on Linux, 1100×800, light theme, fresh isolated databases, identical synthetic quotas. Stills were captured after screenshots 500 ms apart matched.
scenarios:prove exited 0: failed on base, passed on head. The opened report retains the custom endpoint’s “no subscription limits” notice and labels the hub account separately.
AI-assisted; verified with the tests and tools listed above.
Not shown:
Live subscription accounts and external hub connectivity were not exercised; quota readings came from a synthetic local CLIProxyAPI-compatible endpoint.
