fix: use actual data extent for CommitmentKey in HypernovaDeciderProver - #21206
Merged
Conversation
After PR #21179 optimized `compute_new_claim()` to move polynomials instead of copying, the `virtual_size()` of accumulator polynomials no longer reliably reflects the accumulator's dyadic size. Use the explicit `dyadic_size` field which is always set correctly. This fixes WASM chonk integration tests that failed because `virtual_size()` returned 2^21 (CONST_FOLDING_LOG_N) causing CommitmentKey to request more CRS points than available.
Use `end_index()` to compute the tightest CRS size needed, rather than `dyadic_size` (which can be 2^21). Pass `dyadic_size` to the batcher and Shplemini (which need the multilinear domain size) but only request as many CRS points as the polynomial data actually requires.
