etcd's checkTxnRequest/checkRequestOp recurse into nested txns with a shrinking maxTxnOps-opc budget (v3rpc/key.go), so a deeply nested txn cannot exceed the total. app/etcd/txn.lua:235-244 validate_request checks only TOP-LEVEL counts against a hardcoded MAX_TXN_OPS = 128 (txn.lua:210). A nested txn tree can therefore carry far more than 128 ops. No role-config knob. The top-level limit and the error message match etcd exactly, so this is narrow: make check recursive with a shrinking budget, add a max_txn_ops option.
A nested txn exceeding the total budget is rejected with etcd's message; limit configurable via roles_cfg; test covers the nested overflow.
No outgoing dependencies.
Nothing depends on this issue.
