/**
 * Staging test account (OPS125) — the ONE source of the synthetic `campaignUser`
 * used for manual testing at `https://staging.jorgesolla1313.com.br` (the
 * mandatory `work-issue` post-deploy verification that used it was removed in
 * OPS128; the infrastructure stays as reusable tooling — runbook §Staging).
 *
 * Why it exists: the minimal seed credentials never exist on staging (the
 * staging DB is a copy of production, not a `db:seed:minimal` target), so
 * testing there needs a dedicated account. This module owns the account
 * identity and the fail-closed guard that keeps its creation restricted to
 * staging.
 *
 * The password is NEVER in code — it comes from `STAGING_TEST_ACCOUNT_PASSWORD`
 * in the homeserver env file (`~/stack/teqo-staging.env`, chmod 600), so the
 * re-run is idempotent AND deterministic.
 *
 * Guard discriminators (the host alone cannot decide: the homeserver socat
 * proxy rewrites the DB host to 127.0.0.1 and the env file sets
 * `NODE_ENV=production`, so `assertLocalDatabase`/`requiresWriteConfirm` alone
 * cannot tell staging from production):
 *   1. the database NAME must be exactly `teqo_staging` (the honest signal);
 *   2. the protocol must be `postgresql:`;
 *   3. the host must still be in the local allowlist (defense in depth);
 *   4. `ALLOW_REMOTE_DB` is refused (this script never needs it);
 *   5. `TEQO_ENV`, when set, must be `staging`;
 *   6. the explicit intent flag is ALWAYS required — the bootstrap is a
 *      deliberate act, never a side effect.
