/**
 * SuiNS leaf-subname smoke test (mainnet).
 *
 * De-risks SPEC 10 v0.2.1 Phase A.1 (`@t2000/sdk` `suins-leaf.ts` builders).
 * Verifies that:
 *   1. `createLeafSubName` works against the audric.sui parent NFT
 *   2. The leaf resolves via Sui RPC `suix_resolveNameServiceAddress`
 *   3. `removeLeafSubName` revokes the leaf cleanly
 *   4. The leaf no longer resolves after revocation
 *
 * Outputs:
 *   - Two mainnet tx digests (audit trail for RUNBOOK_audric_sui_parent.md)
 *   - Working tx-fragment shape (becomes Phase A.1 SDK-builder seed)
 *   - Gas-cost observation (validates the "$0 per signup" pitch math)
 *
 * Default: dry-run only (safe to run without flags — no on-chain writes).
 * To execute on mainnet: pass `--execute`.
 *
 * Env vars (set in .env.local at workspace root):
 *   AUDRIC_PARENT_OWNER_KEY   Private key of the address that owns the parent NFT.
 *                             This is the dedicated parent-custody key — DIFFERENT from
 *                             T2000_PASSPHRASE (the dev wallet used by other test scripts).
 *                             Per SPEC 10 v0.2.1 D5, the parent NFT lives on its own
 *                             hardened address (NOT the founder's day-to-day wallet).
 *                             Falls back to T2000_PASSPHRASE if AUDRIC_PARENT_OWNER_KEY unset
 *                             (works only if you happen to use the same key for both).
 *   AUDRIC_PARENT_NFT_ID      Object ID of the audric.sui parent NFT.
 *                             Find via:   sui client objects --address <parent-owner-addr>
 *                                         (look for the SuinsRegistration NFT for "audric")
 *   SMOKETEST_TARGET_ADDRESS  (Optional) The 0x address the test leaf will point to.
 *                             Defaults to the parent owner's own address (safe).
 *
 * Usage (matches existing scripts/test-*.ts pattern):
 *   source .env.local && npx tsx scripts/smoke-suins-leaf.ts            # dry-run only
 *   source .env.local && npx tsx scripts/smoke-suins-leaf.ts --execute  # actually mints + revokes on mainnet
