 This checks that the eleven recorded Mainnet DODO cW bootstrap pools (USD rails + non-USD Wave 1 + `cWUSDT/cWUSDC`) are still mapped by the integration, have non-zero reserves, and remain dry-run routable through the repeatable swap helper.
 
+**Current micro-support sweep (default dry-run):**
+```bash
+bash scripts/deployment/run-mainnet-cw-micro-support-round.sh --dry-run
+```
+This runs the currently validated tiny support swaps for `cwusdt-usdt`, `cwusdc-usdc`, `cwusdt-usdc`, and `cwusdc-usdt` in sequence, then points back to `check-mainnet-pmm-peg-bot-readiness.sh`.
+
+Re-run with `--apply` only when you intentionally want to broadcast the full four-leg support round.

 ### 15. Mainnet DODO Wave 1 pool deploy helper
