The 1x gate is green; the 5x failed iters 1-2 on readiness-under-churn (apps DO
recover — lnd synced, mempool just mid-restart when probed — but slower than the
windows when restarted back-to-back). Hardening:
- run-20x.sh: best-effort settle_stack() before each iteration (wait for
mempool-api/frontend + lnd RPC healthy, 180s, on-node, never fails the run).
- required containers present/running (80/81): wait-loops (180s) not single-shot.
- mempool api/frontend (87/88): retry ~180s not single-shot.
- mempool queryable (74): 60s->180s. lnd restart-running (64): 120s->240s.
lnd getinfo (60): 90s->240s retry.
