 ### Fixed
 
+- Fixed legacy Pi extensions failing validation when importing the upstream `keyText` keybinding helper ([#6470](https://github.com/can1357/oh-my-pi/issues/6470)).
 - Fixed a path traversal vulnerability in blob reference resolution by rejecting non-canonical hashes in `parseBlobRef`.
 - Fixed multiple edge cases in the secret obfuscation and redaction engine, including handling of context-sensitive regexes, placeholder key requirements in unwritable directories, friendly-name forgery vulnerabilities, and regex match boundaries straddling existing placeholders.
 - Fixed a first-use race condition in `ArtifactManager` where concurrent callers could allocate duplicate artifact IDs.
