98-101: Fix typo and enhance field documentationThe documentation has a typo and could be more comprehensive about the cancellation status determination.
Apply this diff to improve the documentation:
// This field indicates whether the booking can be cancelled. If this field - // is not used, the default value is false, whick means the booking cannot be + // is not used, the default value is false, which means the booking cannot be // cancelled. + // This status is determined by the supplier at booking time and remains immutable + // for the lifetime of the booking. bool cancellable = 12;
97-101: Consider documenting on-chain implicationsSince this is part of an on-chain booking system, it would be helpful to document:
- How this flag affects smart contract behavior
- Whether additional on-chain validation is required
- Future considerations if cancellation requires more metadata (e.g., cancellation fees, deadlines)
Consider adding these details to the protocol documentation or creating a separate architectural decision record (ADR) to capture these design decisions.

97-101: LGTM! Change is backward compatible and follows best practices
The addition of the cancellable field is well-designed:
- Optional field with default value ensures backward compatibility
- Field number 12 maintains proper message evolution
- Placement in MintResponse is appropriate for this booking property
Let's verify no breaking changes were introduced:
✅ Verification successful
LGTM! Change is backward compatible and follows best practices
The verification confirms:
- No duplicate field numbers exist in MintResponse
- All fields from 1 to 11 are present and maintained
- Field number 12 for
cancellableis correctly positioned without conflicts
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Verify backward compatibility by checking for any reuse of field numbers
# or removal of existing fields in the MintResponse message
# Check for any duplicate field numbers in MintResponse
rg -A 1 "= \d+" proto/cmp/services/book/v3/mint.proto | grep "=" | sort -n -k3 | uniq -d -f2
# Verify all previous fields (1-11) are still present in MintResponse
for i in {1..11}; do
rg "= $i;" proto/cmp/services/book/v3/mint.proto || echo "Missing field number $i"
done

We added a field in the Mint response to indicate whether a booking can be cancelled. This is backward compatible amendment at the end of the file.
