/**
 * LIVE multi-account orchestrator e2e (#9960) — the real-account counterpart to
 * the secret-free `compose-multi-account-e2e.ts` (which uses a fake `acpx`).
 *
 * Seeds the account pool from CI/operator-provided real credentials — ≥1 (ideally
 * 2) Claude `anthropic-subscription` OAuth tokens and ≥1 (ideally 2) Codex
 * `openai-codex` `auth.json` blobs — then drives the REAL coding-account bridge
 * to prove, per provider:
 *   - the bridge selects a healthy account and injects its credential into the
 *     spawn env (Claude → CLAUDE_CODE_OAUTH_TOKEN, Codex → per-account CODEX_HOME
 *     with a materialized auth.json),
 *   - consecutive selections ROTATE across DISTINCT accounts when ≥2 are present.
 *
 * Gated by ORCHESTRATOR_LIVE_MULTI_ACCOUNT=1 AND the presence of the credential
 * env vars. With neither configured it SKIPS CLEANLY (exit 0 + ::notice::) so it
 * never fails CI when the live secrets are absent — the scheduled lane relies on
 * this. The proof is selection + credential injection + distinct-account
 * rotation (no real spawn, so it does not burn task quota).
 *
 * Credential env vars (JSON or raw token; 1..N indexed):
 *   ELIZA_LIVE_CLAUDE_OAUTH_TOKEN_1 .. _N   raw Claude Code OAuth token
 *   ELIZA_LIVE_CODEX_AUTH_JSON_1    .. _N    full ~/.codex/auth.json contents
 *
 * Run:
 *   ORCHESTRATOR_LIVE_MULTI_ACCOUNT=1 bun \
 *     plugins/plugin-agent-orchestrator/scripts/live-multi-account-e2e.ts
