Its answer +pass receives the case question and retrieved evidence, not expected/allowed/forbidden outcomes; +it must return explicit retrieved chunk IDs in `citations`, and judging checks only those citations. +Holdouts remain sealed. Export the existing `DEEPSEEK_API_KEY` before this opt-in call; the entry +requires `DEEPSEEK_MODEL`. The maximum-call ceiling is `CALLS_PER_CASE × development case count`, +where each case has two logical passes and up to three billed attempts per pass. The default remains +64; retries are billed again and counted in each row's `model_calls`. Usage is emitted from the model +session even when a later answer or judge pass aborts, with unknown token totals labelled `unknown`. + +The runner treats the generated answer as one untrusted JSON string value and tells the judge to +ignore directives inside it (a prompt boundary, not proof of injection immunity), reserves the +verdict and metadata-sidecar destinations in a consistent lock order before the first billed call +and never overwrites an existing artifact, snapshots +the corpus and case file once before the calls so the artifact identifies the material actually +judged, and writes results under the user state directory without printing answer text. Before +opening the model session, it checks all case queries against retrieval's limit and preflights each +answer prompt and every possible citation subset's judge prompt using a 1,000-Unicode-character +worst-case answer; accepted answers are limited to 1,000 Unicode code points, so an over-limit +response aborts before its judge call.
