+- **fix(dashboard):** pass `nodeMap` into Runtime `QuotaGroup` so a quota monitor in error/exhausted/alerting no longer throws `ReferenceError: nodeMap is not defined`. ([#12868](https://github.com/diegosouzapw/OmniRoute/pull/12868))

QuotaGroup is a module-level sibling and was reading nodeMap from RuntimePageClient's closure; that identifier is not in scope, so a quota monitor with status error/exhausted/alerting throws ReferenceError. Fix threads nodeMap as a prop (3 call sites + parameter + ProviderNodeEntry import). Prettier wraps the long import and the three QuotaGroup JSX tags. Covered by tests/unit/ui/runtime-page-client.test.tsx (empty monitors stay green; error+exhausted fixtures mount QuotaGroup).",

Irreducible wiring at the existing fetchResetAwareQuotaWithCache call site; the family helper itself lives in antigravityQuotaFamily.ts. Covered by tests/unit/reset-aware-request-scope-12600.test.ts.",

Circuit-open pre-skip now records the breaker retryAfter and, when every target was skipped that way, waits the short reset via resolveCircuitOpenWaitDecision (new leaf in comboCooldownRetry.ts) instead of crystallizing ALL_TARGETS_SKIPPED in ~43ms. skippedForCircuitOpen / earliestCircuitOpenRetryMs reset each setTry so a later iteration cannot inherit a stale retryAfter. Irreducible at the existing ALL_TARGETS_SKIPPED chokepoint (same pattern as #7301/#8213 cooldown-wait).
