/**
|
||||
* PIEXTENSIO-18 quality-loop harness (offline, package-local).
|
||||
*
|
||||
* Replays the PIEXTENSIO-4 15-case corpus through the production verdict
|
||||
* path — buildJudgeContext (prompt v2) + requestStructuredVerdict — against
|
||||
* a real provider/model segment resolved from the agent's models.json via
|
||||
* the pi SDK ModelRegistry. Never imported by online modules; no npm bin.
|
||||
*
|
||||
* Usage:
|
||||
* npx tsx packages/pi-permission-ai-judge/tools/corpus-replay.ts \
|
||||
* --provider openai-codex --model gpt-5.6-sol [--thinking high] \
|
||||
* [--timeout-ms 30000] [--case requested-clean,...] [--out file.json]
|
||||
*
|
||||
* Exit code: 0 if the replay completed (regardless of matches — matches
|
||||
* are quality data, not CI assertions; PIEXTENSIO-11 discipline retains
|
||||
* unfavorable rows), 1 on harness/setup failure.
