+ * The capacity a batch may run on: batchCapacity(model, at).
+ *
+ * A batch is half price for the customer, so every token of it must cost the network at most half of the
+ * card the customer is charged. The retail card IS the provider's own list price (server/providers/
+ * model-catalog.js copies the model row's cost; there is no mark-up on it), so a batch that ran on an
+ * ordinary paid route would cost the network the full price while the customer was charged half: the
+ * network would lose money on every token of it.
+ *
+ * So a batch runs only where the money works out. Three kinds of route are eligible:
+ *
+ * (a) capacity that costs the network nothing: OpenVibe's own GPU and local deployments (idle capacity
+ * the network already pays for) and any free provider;
+ * (b) a community machine offer whose credit price for the model is at most half the requested model's
+ * retail: the seller is paid their price and the network keeps the rest, which is never negative.
+ * A community credit is the same unit the Balance ledger counts (the nano), so the two prices are
+ * compared as they are;
+ * (c) a paid provider inside a window where the provider's own price, read from the price book, is at
+ * least 50% lower than the retail card. DeepSeek's off-peak window is the case today. A provider the
+ * price book has no window for is not eligible: the network cannot tell what that route costs, and
+ * a batch is never run on a price nobody knows.
+ *
+ * The function returns the eligible routes with their real cost, and the card the customer is charged.

+ * The batches: many prompts submitted at once, answered later, at half the retail price.
+ *
+ * How a batch works:
+ *
+ * - Submitting it queues it, with a deadline (the customer sets it, 1 to 72 hours; the default is 24).
+ * The prompts are answered when the capacity is there, and they expire at the deadline if it is not.
+ * - The money goes through Billing like every other request: a batch item is an ordinary run, and the
+ * run's Balance session is charged with the half-price retail card. This table is the queue and the
+ * status, never a second ledger.
+ * - The owner is the account that pays: a person (their personal Balance) or a developer app (its
+ * project's Balance). A service token with no account of its own may not open a batch, because
+ * nobody could be charged for it.
+ * - A batch carries at most config.batches.maxItems prompts. A bigger one is refused at the door.
+ *
+ * The capacity rule (server/batch/capacity.js): a batch is half price for the customer, so it may only run
+ * where the route really costs the network at most half of the retail card: OpenVibe's own GPU and local
+ * capacity and free providers, a community offer that asks at most half, or a paid provider inside a
+ * price-book off-peak window. The scheduler holds an item until such a route exists.
+ *
+ * The settle check: the run settles only if the route it really used costs at most what the customer was
+ * charged. If it does not, the settle is refused and the item keeps waiting; nothing is charged.
+ *
+ * The owner's loss budget (ai.batches.loss_budget_usd_per_day): when it is above zero, an item that reaches
+ * its deadline may run on ordinary capacity, and the network absorbs the difference, up to that budget per
+ * UTC day. Every absorbed amount is written on the item, and the batch says it ran on regular capacity.
+ *
+ * The queue lives in the database, so it survives a restart. Several workers run this service, so a worker
+ * claims one item at a time (the claim expires on its own if that worker dies) and takes the oldest item

+ *
+ * The refusal side:
+ *
+ * - the job is due-based: its last run is a row in the database, so a restart in the middle of the
+ * week does not measure the offers again, and a week later it is due again;
+ * - the rate is the refusals over the attempts, written with the day it was measured, and an offer
+ * nobody measured stays unknown (never zero).
+ *
+ * The batch side, which is where the money is: a batch is half price for the customer, so it may only
+ * run where the route really costs the network at most half of the retail card (server/batch/capacity.js).
+ *
+ * - an item on an ordinary paid route outside a discount window never runs: it expires uncharged;
+ * - an item on OpenVibe's own route runs, and the customer is charged half;
+ * - a community offer above half the retail price is not eligible;
+ * - at the deadline with no budget the item expires, uncharged;
+ * - with a loss budget it runs on regular capacity, and the absorbed amount is recorded and capped
+ * per day;
+ * - the settle check refuses a route whose cost exceeds the charge.
