+"playground-cli": patch
+---
+
+`dot init` now shows the user's registry username (the handle set on the
+playground.dot profile) when one has been claimed, falling back to the
+People-parachain identity name and then to the H160, same precedence as
+the playground-app. Also surfaces an "account in use" row with the
+derivation path + H160 so the user can verify the exact account that
+signs on their behalf.
+
+`dot deploy --playground` now matches the v11 registry contract's 7-arg
+`publish()` signature (adds `modded_from`, `is_moddable`, `is_dev_signer`),
+which unblocks publishes against the freshly deployed playground registry
+on Paseo Asset Hub Next. `cdm.json` is refreshed to the v11 manifest; the
+runtime keeps resolving the live contract address from the on-chain
+meta-registry.
