Retain the first fatal preparation or round-processing error and stop subsequent updates from storing messages or advancing the party. Input-validation and message-storage rejections remain recoverable. Check the expected keygen commitment part count before hashing and point decoding.

16938849b0f49bf925ea3902f5fab21b9ea9904b.Validation:
go test -p 1 ./tss ./ecdsa/keygen -run 'TestBaseParty|TestUnmarshalVSSCommitmentPartCount' -count=1passed withGOMAXPROCS=2. Tests cover each fatal-error source, retained error identity, recoverable rejections, normal progression, and valid/invalid commitment shapes. Full owning suites also passed withgo test -p 1 ./tss ./ecdsa/keygen ./ecdsa/signing -count=1 -timeout=30m(keygen completed in about 16 minutes). Formatting, diff checks, and independent patch review passed.
