SikongJueluo 99e953664d refactor(ai-judge): group src modules into domain directories
- move evidence.ts and conversation.ts into evidence/ as bash.ts and conversation.ts
- move prompt.ts and model.ts into judge/
- move highrisk.ts and judge.ts into authority/, renaming judge.ts to enforce.ts to avoid clashing with the judge/ directory
- move review.ts and audit.ts into telemetry/
- move config.ts and catalog.ts into config/ as judge.ts and catalog.ts
- rewrite static and dynamic imports across src, tools, and tests to the new paths
- fix the models-catalog.json relative URL broken by the move (caught by fallow unresolved-import)
- update the PIEXTENSIO-12 module map in the ADR to the new paths
- add editorconfig for 4-space ts indentation

/**
* 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 \
* [--timeout-ms 30000] [--case requested-clean,...] [--out file.json] \
* [--strict]
*
* Exit code: 0 if the replay completed and (with --strict) qualified;
* 1 on harness/setup failure; 2 with --strict when the replay completed
* but failed the light qualification standard (see tools/replay-qualify).
* Without --strict, mismatches are quality data, not CI assertions
* (PIEXTENSIO-11 discipline retains unfavorable rows; exit 0 keeps them).
