  * OpenRouter — GET https://openrouter.ai/api/v1/credits with Bearer auth.
  * Returns { data: { total_credits, total_usage } } where both are USD floats.
- * Used relative to the user's purchased credits, not a rolling window.
+ *
+ * Important: SF's built-in policy (preferences-models.js:123-131
+ * isModelAllowedByBuiltInProviderPolicy) restricts OpenRouter routes to
+ * `:free` + zero-cost models for ALL SF users, no opt-in needed. Routing
+ * through SF therefore never consumes credits — the credits balance is
+ * historical noise, not a signal for the quota-aware router.
+ *
+ * The window IS reported (so `sf headless usage` can display credits state
+ * for user awareness) but `usedFraction` is deliberately left undefined so
+ * benchmark-selector's quotaHeadroomMultiplier treats OpenRouter as "no
+ * quota signal" (neutral 1.0) rather than incorrectly demoting at the
+ * credits high-water mark.
