chore: erase ephemeral secrets from memory in schnorr and aes#21106
Merged
Conversation
added md explaining the flow + a bit of renaming
Primary changes: - Replace methods of the form `get_*_gate_connected_component` with `GatePattern` structs that specify the conditions under which each wire is constrained for each gate type - Test correctness of `GatePattern`'s by perturbing relation inputs to empirically check which wires are constrained (`gate_patterns.test.cpp`) - Resolves a few bugs/errors identified by the aforementioned tests (see PR comments) - Use `update_used_witnesses` in `fix_witness` to avoid need for ad-hoc handling in the tooling Cleanup: - Replace use of `block_idx` with reference to `block` in several places for improved clarity --------- Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>

similar to how it's done in hmac, we should make sure we remove secret randomness that are no longer from memory.
