 **Speed / reliability (default suite):** prefer `pad_empty_from` / `build_mature_regtest_with_spend` **once per journey** (tx_relay live hub, Electrum protocol, core_analogs assumevalid+mempool) over remine pads; SH run-builder sleeps are 1 ms under `cfg(test)` (40 ms in production). `pin_compose_multi_pack_timed` keeps functional + layout/covered short-circuit gates (multi-ms floor); sticky vs cold assemble is log-only (not a hard timing assert). Schema-13 wire rebuild must stamp create identity from `txid.body` — zero batch identity is treated as missing (regression covered by `reconstruct_and_connect_error_arms` + multi-vout confirm scenarios). Coverage vs speed: prefer **one** scenario at the real entry over N micro-opens that only paint lines; when adding coverage for reduce/materialize, use a **tiny** target, not production stream depth.
