hailin 51c0f59924 fix(tss): remove threshold-1 in signing to match keygen exactly ... The signing code was using thresholdT-1 while keygen was using thresholdT, causing Lagrange coefficient mismatch and "U doesn't equal T" error in round 9. Root cause: commit d0c504dc added -1 to signing threshold to "match user expectation", but this broke the keygen/sign consistency that TSS-lib requires. Changes: - tss-party/main.go: Sign now uses thresholdT (same as keygen) - pkg/tss/signing.go: Add logging, emphasize threshold must match keygen - tss-wasm/main.go: Add comment about threshold consistency NOTE: This fix maintains backward compatibility with existing wallets. No wallet regeneration is needed. ROLLBACK: If this causes issues, revert to commit before this one. Previous signing threshold was thresholdT-1 (commit d0c504dc). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>		2025-12-31 12:08:40 -08:00
