/**
 * PIEXTENSIO-21 owner action CLI (offline, package-local).
 *
 * Appends one promotion record to the Judge-owned records file
 * (~/.pi/agent/extensions/pi-permission-ai-judge/promotion-records.jsonl).
 * Never imported by online modules; no npm bin. The three record kinds map
 * one-to-one to the Enforce truth-table promotion gates:
 *
 *   cohort_qualified — after a declared replacement cohort meets the frozen
 *                      floor, citing the cohort id + report reference
 *   owner_approval   — the owner's explicit approval of that exact candidate
 *   activation       — the distinct, explicit activation act
 *
 * Fail-closed contract: a record qualifies only its exact candidate
 * identity; the judge re-derives identity from the live runtime, so a
 * mismatched or malformed record is inert and malformed files close all
 * gates. There is no CLI to *remove* authority records by design —
 * rollback to Shadow is the config `mode` switch, and the append-only
 * trail keeps the promotion history auditable.
 *
 * Usage:
 *   npx tsx tools/promotion-record.ts --kind cohort_qualified \
 *     --provider openai-codex --model gpt-5.6-sol --api openai-codex-responses \
 *     [--timeout-cohort 30000] --basis "cohort <id>; report docs/testing/..."
 *
 * judge/permission-system/prompt/tool-schema/review-schema versions are
 * taken from the live package (src/prompt.ts + package constants) so the
 * recorded identity cannot drift from the code that will check it.
