Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The title mentions 'bech32 addresses' but the actual changes focus on v2 asset locks with automatic credit assignment and P2PKH/P2SH support, with only an indirect reference to address encoding (DIP-0018) rather than bech32 implementation.	Consider revising the title to accurately reflect the main changes: 'docs: v2 asset locks with automatic credit assignment' or similar, removing the misleading 'bech32 addresses' reference.

In `@dip-0027.md`:
- Line 91: Update the DIP text to avoid ambiguity by replacing references to
"pubkey" with "pubkey hash" where appropriate: specifically clarify that in a
`version = 2` Asset Lock transaction each entry in `credit_outputs` MUST be
credited to the Identity matching the entry's pubkey hash (not a raw pubkey) or
script hash, and update any related wording that mentions `pubkey` to `pubkey
hash` to reflect P2PKH locking scripts.

This update is intended to allow sending directly to platform addresses, correct? The text mentions crediting to an identity, but platform addresses aren't linked to particular identities.
