) ## Description Turns out we don't check anywhere that the inputs fit into the field and neither does the poseidon-lite library (it just truncates elements and fits them into the field). Instrumenting poseidon seems like the simplest way to do this. The other option (which I have not taken) is to instrument as soon as we receive some inputs.. ## Test Plan How did you test the new or updated feature? --- If your changes are not user-facing and do not break anything, you can skip the following section. Otherwise, please briefly describe what has changed under the Release Notes section. ### Type of Change (Check all that apply) - [ ] protocol change - [ ] user-visible impact - [ ] breaking change for a client SDKs - [ ] breaking change for FNs (FN binary must upgrade) - [ ] breaking change for validators or node operators (must upgrade binaries) - [ ] breaking change for on-chain data layout - [ ] necessitate either a data wipe or data migration ### Release notes
