Summary

Reopen #7318 against current dev (306a88e08) after the maintainer invited an updated submission. This retains the original branch history without a force push.

  • Add separate Pause/Resume controls for provider API key pools, with accessible pending states and mutation fencing.
  • Preserve the canonical persisted API-key selection transaction, select the next unpaused key in ring order, and refresh configuration/catalog/quota state after a selection change.
  • Refuse all-paused key pools with HTTP 403 permission_error before upstream dispatch, including Vertex ADC/environment fallback, Responses streaming/buffered/compact, Chat, Messages, and Images.
  • Skip paused-key quota probes, retain fresh cached readings, and keep configured providers visible when every stored key is paused.

Reconciliation with current dev

The original four commits (c8a8db814, 08d9e9e7e, 3a12b1ea6, 82c10c98a) were ported onto current dev. The transport inventory conflict preserves upstream additions. A new import cycle is fixed by extracting the pure pause error/predicate into api-key-pause-state.ts, without relaxing the cycle baseline. English and Traditional Chinese documentation distinguish standalone Resume from resume-and-activate row selection.

No dependency, authentication endpoint, OAuth credential-store, CORS, or workflow changes are included. Routing and management changes remain subject to maintainer review.

API key pause and resume controls

Validation

  • Root TypeScript check: passed.
  • Full GUI suite: 3,496 pass, 0 fail; focused final pause/display suites: 30 pass, 0 fail.
  • GUI lint, i18n lint, and production build: passed.
  • Focused backend, canonical selection/transport compatibility, Vertex project lookup, structure and cycle tests: 201 pass, 0 fail.
  • Separate deployment tree based on v2.91.0 + feat(vertex): resolve each API key's project with project "auto" #7296 + this patch: 170 pass, 0 fail across 11 focused test files; root typecheck and GUI build passed.
  • structure:check, privacy scan, file-size/cycle ratchets: checked locally.
  • Independent adversarial reviews covered backend, GUI/documentation, and the feat(vertex): resolve each API key's project with project "auto" #7296 interaction; the discovered import cycle and Resume documentation mismatch were fixed.
  • Broader bun scripts/test.ts --changed=dev --parallel=2 is still running. The full root suite has not been claimed as passing. This PR remains draft pending broader validation and current-head upstream checks.

The deployment uses the explicitly requested v2.91.0 baseline; this PR targets current dev and does not alter its version line.

Review readiness checklist

  • Required local validation passed; commands, results, and any full-suite exception are documented.
  • I pushed my PR to a recent dev commit (at most 10 behind; a maintainer may still ask for the exact tip before merge).
  • I resolved all correct Codex and CodeRabbit findings.

📝 Walkthrough

API-key pools now support pausing and resuming individual keys. The change updates active-key selection, provider availability, request error handling, management and CLI responses, and provider-workspace controls.

Changes: API-Key Pause and Resume

Layer / File(s) Summary
Pause state and key selection
src/providers/api-key-pause.ts, src/providers/api-keys.ts, src/providers/key-failover.ts, tests/providers/api-key-auto-pause-distribution.test.ts
Pause state determines key eligibility. Pausing or resuming can repair the active key in pool order. Key addition, removal, proactive selection, and distributed allocation account for disabled entries. Tests cover active-key handoff and resuming from an all-paused pool.
Paused-key provider eligibility
src/adapters/google.ts, src/codex/catalog/provider-models.ts, src/providers/openai-sidecar.ts, src/providers/quota-key-accounts.ts, src/router.ts, structure/transports/inventory.md, tests/providers/api-key-auto-pause-distribution.test.ts
Paused keys affect Google request construction, model discovery, Images provider selection, quota probes, and cross-provider redirects. Tests check quota behavior and static model discovery when keys are paused.
Paused-key request responses
src/server/chat-native.ts, src/server/messages-native.ts, src/server/images.ts, src/server/responses/*, tests/providers/api-key-auto-pause-distribution.test.ts
Request handlers return 403 permission_error when a paused key blocks dispatch. Responses run-turn handling retains pause refusals through preflight. Tests cover requests when all keys are paused and failover around a paused key.
Management and CLI pause results
src/server/management/config-routes.ts, src/server/management/provider-routes.ts, src/providers/api-keys.ts, src/cli/account-extended.ts, tests/cli/cli-account-key-pause.test.ts, tests/providers/api-key-auto-pause-distribution.test.ts
Management responses report stored API-key presence for key pools. CLI pause and resume output includes the resulting active account and whether it changed. Tests cover the reported account and stored-key status.
Provider workspace pause controls
gui/src/components/provider-workspace/*, gui/src/pages/Providers.tsx, gui/src/hooks/useProviderAccountPools.ts, gui/src/i18n/*, gui/tests/account-pause-display.test.tsx, gui/tests/provider-account-pause-refresh.test.tsx
The workspace provides pause and resume controls, displays paused-key state, and guards concurrent switching and pause operations. The hook updates the roster and refreshes configuration and quotas as needed.

Merge Risk: ⚪ Minimal · up to 82c10

Operators can now pause and resume individual API keys in a provider pool. Paused keys are skipped during selection. When every key in a pool is paused, inference requests are rejected with a permission error instead of falling back to other credentials. Requests are checked for paused keys before dispatch. Earlier problems with the GUI refresh, accessible labels, and missing test coverage have been addressed, and no outstanding defect blocks this merge.

Review comments at @gui/src/components/provider-workspace/ProviderAuthPanel.tsx:
- Line 727: Give the paused-key main row button a distinct accessible name that
conveys both resuming and activating the key, while keeping the dedicated resume
button’s name unchanged. Add the corresponding `pws` translation key to every
locale dictionary and use it in the main row button’s `aria-label`.

Review comments at @src/cli/account-extended.ts:
- Around line 851-858: Update the `wantsJson` output in the API-key pause/resume
flow to include the active-account change reported by `result.json`: expose the
active ID using `activeAccountId` with `activeId` as fallback, preserving `null`
when neither is present, and include whether `activeAccountChanged` is true.
Keep the existing text-mode output unchanged.

Review comments at @src/providers/key-failover.ts:
- Line 570: Update the compact-path catch in `selectProactiveApiKeyTransport` to
map `ProviderApiKeyPausedError` to the same 403 `permission_error` response used
by the Responses transport, while preserving the pacing-overload handling and
rethrowing unrelated errors.

Review comments at @src/server/management/provider-routes.ts:
- Around line 905-906: Extract a shared helper that determines whether a
provider has a stored API key, including a non-empty pool for providers whose
auth mode is neither OAuth nor forward. Use it for `hasApiKey` in the provider
listing, `auth-cors.ts`, and the PATCH response in `provider-routes.ts` so all
three report the same result.

Review comments at @src/server/responses/request-transport.ts:
- Around line 643-646: Update the catch around refreshDispatchAdapter in
oauthDispatch to handle ProviderApiKeyPausedError (through its
OAuthAccountPausedError base) by returning a 403 permission_error response using
the existing public OAuth error message formatter. Preserve the existing
admission-denial and Copilot-refusal handling for other errors.

Review comments at @structure/transports/inventory.md:
- Line 48: Update the API-key pools contract row to document that without an
apiKeyPoolStrategy, a paused committed key—or a missing apiKey when the pool
contains paused entries—selects the first enabled key as fill-first before
dispatch. Preserve the existing configured-strategy, 429, mirroring, and
paused-entry behavior descriptions.

Intake/scoped review at 82c10c98adf591ac7b2dbadb1b8650e9db52a839.

Manual key pause/resume spans inference, catalog/quota reads, GUI and management persistence. Keep all-paused distinct from an absent key so Vertex cannot fall through to ambient credentials, and keep per-key observation/selection state well defined during idempotent actions and active-key transitions. src/router.ts is owner-only; final routing/UI and authentication-boundary review remain required. This intake does not approve those surfaces or change a live pool.

Current-head functional workflows are awaiting fork approval; that is pending execution, not a passing test result. No local suite was run for this branch in this intake. No workflow approval, new scan, live configuration change or merge was performed. Required review/readiness gates remain in force.

Thank you for the work here. We're closing this to keep the review queue manageable: it conflicts with dev and is mainly a dashboard change, which is outside the current provider and bug-fix sweep. You're welcome to reopen this or open a smaller PR against dev.
