   I checked this against the current release — it appears to be fixed in @meshsdk/core@1.9.1, so this issue can probably be closed.

   Reproduction from the report (SDK 1.9.0-beta.69):

   deserializePoolId("pool107k26e3wrqxwghju2py40ngngx2qcu48ppeg7lk0cm35jl2aenx");
   // threw: resolveEd25519KeyHash: ... Enterprise address data length should be 29 bytes long

   Verified today with the published 1.9.1 packages (Node, clean install):

   import { deserializePoolId } from "@meshsdk/core";
   deserializePoolId("pool107k26e3wrqxwghju2py40ngngx2qcu48ppeg7lk0cm35jl2aenx");
   // → "7facad662e180ce45e5c504957cd1341940c72a708728f7ecfc6e349"

   The CSL serializer backend returns the same value:

   new CSLSerializer().deserializer.cert.deserializePoolId(
     "pool107k26e3wrqxwghju2py40ngngx2qcu48ppeg7lk0cm35jl2aenx",
   );
   // → "7facad662e180ce45e5c504957cd1341940c72a708728f7ecfc6e349"

   Cross-check with the repo's own test vector to make sure the outputs are right, not just non-crashing: pool1lzg07gaddygem6f5ch60yv0l0g2529af87hqgw6gkqdmsfs39z9 → f890ff23ad69119de934c5f4f231ff7a154517a93fae043b48b01bb8 on both backends, matching packages/mesh-core/test/utils.test.ts.

   The current implementation decodes the pool id through the PoolId type (packages/mesh-core/src/utils/deserializer.ts) instead of routing it through address/key-hash resolution, which is what produced the 29-byte enterprise-address error in the beta.
