**Impact:** repository cleanup only — no cluster references these modules, nothing redeploys **Risk:** low Delete `modules/arc-runners-opt` and `modules/nodepools-opt` in full. meta-prod-aws-ue1 was the only consumer and has been cut over to the regular `arc-runners`/`nodepools` modules, which now carry the same optimizations. With no cluster referencing them, these directories are dead code. - The generic `-opt` suffix handling in the shared scripts (shard grouping, module-gate normalization) is intentionally left in place — it operates on in-memory config, not these directories, and keeps working for any future `-opt` canary. `just lint`/`just test` pass, including the tests that exercise that suffix logic. ghstack-source-id: 10fc124 Pull-Request: #904
