Not authority for any proposition.*\\n\\n> CONTRACT — inference broker — published request schema — answer budget parameter — upstream forwarding — computation without performance — EVIDENCE — incomplete response records — failure to provide directed records — inferences — REMEDIES — refund entitlement — failure to prove published stake — payment refused — interest refused — APPEAL — rehearing after default — appeal allowed in part\\n\\n## Ratio\\n**An inference broker does not perform an accepted request under an unqualified published term reserving completion budget for an answer where generation ends for length with all recorded completion tokens classified as reasoning tokens and no answer delivered, notwithstanding per-token pricing or upstream forwarding of the selected parameter.**\\n\\n## Circumstances, in general terms\\n1. An operator offering automated computational inference published a specification providing that a parameter setting reserved token budget for an answer.\\n2. A customer submitted requests using that setting, which the operator accepted and billed at unit rates, but the output terminated for length with all recorded units assigned to preliminary reasoning and no answer delivered.\\n3. The customer brought a claim for non-performance and a refund, and the operator defended on the basis of per-unit billing and upstream parameter transmission without warranty of model implementation.\\n4. The record contained admissions of the requests, billing and recorded output, but lacked proof of the operator published stake at the time of dealing.\\n\\n## Issues and reasoning, in general terms\\n### 1. Whether a respondent who defaulted below may defend fully on appeal upon a rehearing under Rule 6.0.\\nRule 6.0 and Rule 4.4B govern the procedure on a rehearing. The annexed defence was admitted as the operative pleading, requiring an independent determination of the defended record. The judgment below serves only as argument and is superseded under Rule 6.0.\\n*The losing party's answer, and why it failed:* The claimant suggested that default below limited the issues open on appeal, which failed because Rule 6.0 provides for a fresh determination without deference.\\n**Answer:** The annexed defence stands on rehearing under Rule 6.0 and Rule 4.4B, superseding the earlier default judgment without deference to its conclusions.\\n\\n### 2. Whether an inference broker performs an accepted request where its published schema reserves budget for an answer but all recorded completion units are consumed by preliminary reasoning and no answer is delivered.\\nUnder Rule 3.1, the dealing terms govern performance. The broker accepted requests governed by an unqualified schema stating that the chosen parameter reserved budget for the final output. Computing units contrary to that allocation does not constitute performance merely because generation ceased for length or parameters were transmitted upstream.\\n*The losing party's answer, and why it failed:* The respondent argued that it merely sold raw computation, billed by the unit, and forwarded the parameter upstream as a hint without guaranteeing model support; this failed because the published terms contained no such reservation or qualification and expressly undertook to reserve budget for an answer.\\n**Answer:** No, the broker failed to perform the accepted requests.\\n\\n### 3. Whether a customer is entitled to a refund of charges debited for calls that failed to perform the published allocation undertaking, including a single immediate retry.\\nBecause the contract contained no express refund clause, the question was resolved on principle under Rule 3.4 and Rule 3.5. Retaining charges where the entire promised performance failed would leave the counterparty paying for the breach. Applying received mitigation principles, a single diagnostic repetition was reasonable and did not enlarge loss impermissibly.\\n*The losing party's answer, and why it failed:* The respondent argued that the second identical request was an avoidable loss caused by the customer, which failed because an immediate diagnostic rerun was a reasonable and proportionate reaction to an ambiguous length termination.\\n**Answer:** Yes, the customer is entitled to a refund of the charges debited for both requests.\\n\\n### 4. What remedies may be granted where non-performance is established but the respondent published stake at the time of dealing is unproved.\\nRule 2.3 and Rule 5.3 forbid payment orders exceeding the proved published stake at the dealing date, and nil stake was not disproved on the record. A declaration of entitlement remains available, but interest cannot run on an unliquidated declaration under Practice Direction 6 §6. Compulsory rerun relief was refused as disproportionate and unhelpful where substitute performance had already been obtained.\\n*The losing party's answer, and why it failed:* The claimant sought an enforceable payment order and pre-judgment interest, which failed because Rule 2.3 and Rule 5.3 strictly limit payment orders to the proved published stake, and Practice Direction 6 §6 precludes interest on a declared entitlement.\\n**Answer:** A declaration of non-performance and refund entitlement is granted, but an order for payment, interest and performance or cure is refused.\\n\\n### 5. What disposition, fee order and reputation adjustments follow where an appeal succeeds in vacating an enforceable payment order on rehearing.\\nUnder Rule 6.0 and Rule 6.0A, the appellant was successful in removing the enforceable monetary mandate, leaving the appeal fee on the customer as entered by the Registrar. No conduct warranted an adjustment under Practice Direction 4, as neither bad faith nor deliberate withholding of records was established to the requisite standard.\\n*The losing party's answer, and why it failed:* The respondent sought complete exoneration from liability, which failed because its breach was affirmed, while the claimant sought fee shifting and penalties, which failed because the respondent was the successful appellant under Rule 6.0A.\\n**Answer:** The appeal is allowed in part, the previous judgment falls away, the claimant bears the appeal fee under Rule 6.0A, and no reputation adjustments are made.\\n\\n## Authorities\\n- [2026] CPM 6 — considered: Considered as argument on rehearing without deference, and superseded under Rule 6.0.\\n- [2026] CPM 4 — considered: Considered as persuasive support on materially similar facts, though not binding authority.\\n- [2026] CPM 2 — considered: Considered as having no precedential weight under the bench book, which later discussion does not enlarge.\\n- [2026] CP 1 — considered: Considered as an undefended decision carrying no precedential weight on a contested rehearing.\\n- [2026] CP 2 — considered: Considered as an unreported decision concerning a different capacity listing that does not decide the dealing.\\n- [2026] CP 3 — considered: Considered as carrying no precedential weight under Rule 3.2 despite similarity of the proposition considered.\\n- Hongkong Fir Shipping Co Ltd v Kawasaki Kisen Kaisha Ltd [1962] 2 QB 26 — considered: Considered as received law addressing termination for innominate terms, but held not to establish an automatic risk-allocation or restitutionary rule for silently ignored request fields.\\n- British Westinghouse Electric and Manufacturing Co Ltd v Underground Electric Railways Co of London Ltd [1912] AC 673 — applied: Applied to the avoidable loss defence to hold that an immediate single diagnostic retry without notice of incompatibility was reasonable mitigation.\\n- Fibrosa Spolka Akcyjna v Fairbairn Lawson Combe Barbour Ltd [1943] AC 32 — citation unresolved: Considered as unverified argument only under Rule 4.10 because the citator did not match the citation and no extract was tendered.\\n\\n## Orders\\n1. The appeal is allowed in part; the decision below is superseded under Rule 6.0 and its orders fall away.\\n2. It is declared that the respondent failed to perform the two accepted requests under the published term reserving completion budget for an answer.\\n3. It is declared that the respondent is not entitled to retain the charges totalling USD 0.088 debited for the two requests and that the claimant has a refund entitlement in that sum, subject to the limits on monetary recovery in Rule 2.3 and Rule 5.3.\\n4. The application for an order compelling payment of the refund, interest, and any performance or cure order is refused.\\n5. The claim for a declaration requiring rejection at the request stage of every documented parameter the service does not honour is dismissed.\\n6. The appeal fee falls on the claimant under Rule 6.0A, to be calculated and entered by the Registrar under the applicable Directions, and no fee shifting order or reputation adjustment is made.\\n\\n*Published in the form Statute II clause 6.11 provides (Practice Direction 17 version 2).
