- bootstrap: split mnemonic export (SC2155), PMM_SOAK_RPC_URL_OVERRIDE, noprofile fund-grid, ASCII echoes, help header only
- chain138-tick: document POOLS global for SC2153
- random/grid bots: log line references INTEGRATION, USD bounds, gold, gas, log_tag (SC2034)
- validate-config: ShellCheck all 11 PMM soak + chain138-pmm shell scripts incl. smoke + bootstrap
