CMP20 sub-codes (0x60xx). Distinct from GG18’s 0x50xx so callers can disambiguate the source scheme from a numeric code alone.

Variants

BAD_SHARE = 24_577

A share blob failed to deserialize or had the wrong magic / version. Caller action: regenerate shares via DKG; the on-disk format may have been corrupted or written by a different scheme.

VSS_VERIFY_FAILED = 24_578

A party’s VSS commitment did not verify against the polynomial shares it claims to distribute. Indicates a malformed or malicious share submission. Caller action: treat the contributing party as Byzantine.

BELOW_THRESHOLD = 24_592

Fewer than T shares were supplied for a sign / decapsulation session. The threshold was set during DKG; supplying fewer shares is a programming error, not a network fault. Caller action: collect more shares before retrying.

BAD_ROUND_MESSAGE = 24_608

A round message failed to deserialize or had an unexpected sender / round number. Indicates protocol desynchronization (one party is on a different round than the others) or a buggy / malicious peer. Caller action: abort the session; do not retry with the same message feed.

BAD_PARTIAL_SIGNATURE = 24_624

A partial signature was malformed (wrong length, out-of-range scalar) but the offending party is not identified. This is the non-identifiable-abort path; if identifiable abort is enabled, IDENTIFIED_BYZANTINE is emitted instead.

IDENTIFIED_BYZANTINE = 24_640

Identifiable abort: a specific peer posted an inconsistent partial signature. The carry payload identifies the offending party by its 1-based roster index in the low byte.

INTERNAL = 24_831

Internal error — a panic-equivalent condition was caught and converted to an error return. Indicates a bug in the CMP20 implementation; please open an issue.
