TSS-lib convention: threshold=t means (t+1) signers required.
User expectation: "2-of-3" means 2 signers needed.
Before this fix:
- Keygen used thresholdT directly (e.g., 2)
- TSS-lib interpreted as needing 3 signers (2+1)
- 2-of-3 wallet was actually 3-of-3!
After this fix:
- Both keygen and signing use (thresholdT-1)
- For 2-of-3: tss-lib threshold=1, needs 1+1=2 signers ✓
Files changed:
- tss-party/main.go: keygen and signing both use thresholdT-1
- tss-wasm/main.go: keygen and signing both use thresholdT-1
- pkg/tss/keygen.go: uses config.Threshold-1
- pkg/tss/signing.go: uses config.Threshold-1
BREAKING CHANGE: Existing wallets created before this fix used wrong
threshold and need to be regenerated. New wallets will work correctly.
