+/**
+ * The provider health ledger stands still. When the batch call fails, every
+ * pending card falls back to its own call at once, and each failure is
+ * written to the ledger without being awaited. Background work leaves out a
+ * provider from its third failure in a row on (#1279), so whether a card
+ * still reaches the model depends on how many of its siblings' writes landed
+ * before it read the ledger: scheduling, not code. A ledger that records
+ * nothing and benches nothing keeps every arm's request list exact. The bench
+ * has its own tests (`provider-runner-background-bench.test.ts`, and
+ * `provider-pause.test.ts` for the pause it reads).
