This is a bit nitpicking, I apologize if I misunderstand its meaning.
[L-02] Redundant return value
Function recoverERC20() uses OpenZeppelin's safeTransfer(), which is guaranteed to revert if the transfer fails. Hence, this function will either revert, or return true, making the return value redundant.
All of the events (13 in total) have incomplete documentation
[L-04] Wrong usage of NatSpec format comments
In general, @notice is meant to be a brief description of the function (i.e. what it's supposed to do, in one line), while @dev is meant to provide devs with clarifications, or some notes on function behavior that one might not expect, or anything noteworthy in general.
The report below points out all found instances of tags misusage, along with recommended mitigation. There are four distinct issues in total listed:
All instances below lists two lines, where the @dev-tagged line and the @notice-tagged line are completely the same. Recommendation: remove the @dev line.
All instances below lists two lines, where the @dev-tagged line is just the @notice line with extra details. Recommendation: Remove the current @notice and replace @dev with @notice.
All instances below lists one line, where the comment is descriptive enough to be placed in the preceeding @notice tag, or be its own @dev tag. Recommendation: Either combine them with the preceeding @notice tag, or tag it with @dev.
[N-04] Events can use indexed fields for easier querying
Generally it is a good idea to place indexed fields for database-like data, where it is expected that such data will be queried.
Specifically, the event NewPledge would be extremely helpful to contain indexed fields for creator and receiver, where such values can be expected to be queried by user when needed (e.g. when a receiver wants to query who has pledged them or otherwise).
