Problem

IE3Program exposes validate, verify and publishInput
(packages/interfold-contracts/contracts/interfaces/IE3Program.sol:22, :37, :49). Five
documents still name a validateInput hook, and one of them also attributes it to a caller that
never had it: Interfold has no publishInput.

Separately, docs/pages/write-e3-contract.mdx:51 linked MockE3Program.sol at commit cf50fd6c.
That commit is an ancestor of main, but the file was at packages/evm/ there. #1592 renamed
packages/evm to packages/interfold-contracts, and the link took the new path while keeping the
old pin, so it 404s.

Changes

examples/CRISP/packages/crisp-contracts/README.md described validateInput, called by
Interfold.publishInput, checking the ciphertext with a Greco library at
circuits/crates/libs/greco. None of the three exist. Rewritten against
CRISPProgram.sol:493-554: data providers call publishInput on the program, which checks the
stage and the input window, resolves eligibility from the census, and verifies a Noir proof over
nine public inputs. The Greco relations that proof checks are implemented in
circuits/lib/src/core/threshold/user_data_encryption_ct0.nr, with the witness built in
crates/zk-helpers. The list header said two functions above three bullets.

examples/CRISP/program/README.md tabled validateInput and said all three entry points are
called by the Interfold contract. Added a "Called by" column, because that is the part the old text
got wrong.

docs/pages/best-practices.mdx:23 told readers to implement IE3Program.validateInput.

docs/pages/CRISP/introduction.mdx:110 named validateInput() in the round walkthrough.

docs/pages/write-e3-contract.mdx:51 retargeted to blob/main, matching the convention #1802
established. The #L9 anchor is dropped because line 9 of the current file is blank.

Verification

Check Result
Both removed links 404, followed through redirects
Both replacement links 200, no redirect
CRISPProgram.sol:493-554 line 493 is the publishInput signature, line 554 its closing brace
noirPublicInputs declared size 9, assigned indices 0–8, contiguous, counted by script
Interfold has publishInput no match
CRISPProgram has validateInput no match
pnpm compile (crisp-contracts) 46 files, solc 0.8.28
pnpm build (docs) exit 0, /write-e3-contract prerendered
format:check, check:docs, check:invariants pass
Anchors into either changed page none, so no inbound link breaks

On the Greco attribution: user_data_encryption_ct0.nr:175-178 implements the correct-encryption
relation from eprint 2024/594 directly, together with the
witness range checks, the CRT consistency check on e0, and the batched gamma evaluation.
cargo test -p e3-zk-helpers user_data_encryption passes 8 tests including
test_bfv_ciphertext_to_greco. There is no Noir unit test that exercises the relation itself, so
that part rests on reading the circuit rather than on a test.

Not included

The sequence diagram in the root README.md also names validateInput, but four of its five blocks
disagree with the contracts, so it needs redrawing rather than renaming. Sent separately.

Summary by CodeRabbit

  • Documentation
    • Updated CRISP documentation to describe encrypted vote submission through publishInput, including submission checks, census-based eligibility, and proof verification.
    • Clarified that verifier selection depends on the round census and distinguished the available verifier contracts.
    • Corrected input-validation guidance to reference the current IE3Program.publishInput interface.
    • Refreshed examples with current repository links and clarified contract entry points, callers, and data-provider submission flows.

`IE3Program` exposes validate, verify and publishInput. Five documents still
named a `validateInput` hook, and one of them attributed it to a caller that
never had it.

- examples/CRISP/packages/crisp-contracts/README.md described `validateInput`,
  called by `Interfold.publishInput`, checking the ciphertext with a Greco
  library at circuits/crates/libs/greco. None of the three exist. Rewritten
  against CRISPProgram.sol:493-554: data providers call `publishInput` on the
  program, which checks the stage and the input window, resolves eligibility
  from the census, and verifies a Noir proof over nine public inputs. The Greco
  relations that proof checks are implemented in
  circuits/lib/src/core/threshold/user_data_encryption_ct0.nr with the witness
  built in crates/zk-helpers. The list header said two functions above three
  bullets.
- examples/CRISP/program/README.md tabled `validateInput` and said all three
  entry points are called by the Interfold contract. Added a "Called by" column,
  because that is the part the old text got wrong.
- docs/pages/best-practices.mdx told readers to implement
  `IE3Program.validateInput`, a member that does not exist.
- docs/pages/CRISP/introduction.mdx named `validateInput()` in the round
  walkthrough.

Separately, write-e3-contract linked MockE3Program.sol at commit cf50fd6. That
commit is an ancestor of main, but the file was at packages/evm/ there. theinterfold#1592
renamed packages/evm to packages/interfold-contracts, and the link took the new
path while keeping the old pin, so it 404s. Retargeted to blob/main, matching
the convention theinterfold#1802 established. The #L9 anchor is dropped because line 9 of
the current file is blank.

The sequence diagram in the root README also names `validateInput`, but four of
its five blocks disagree with the contracts, so it needs redrawing rather than
renaming. Left for its own change.

Verified: both removed links 404 and both replacements 200 without redirect,
CRISPProgram.sol:493-554 is exactly the publishInput body, the noirPublicInputs
array is nine and contiguous, Interfold has no publishInput, CRISPProgram has no
validateInput, the CRISP contracts compile, the docs site builds, and
format:check, check:docs and check:invariants pass.

Walkthrough

The documentation replaces validateInput references with publishInput, identifies data-provider callers, documents CRISP census-specific verifier selection, and updates the MockE3Program source link.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to f59ef

The PR corrects stale hook names and a broken source link, but the CRISP introduction still names a single verifier even though verifier selection varies by census mode; this could mislead integrators, so merge is appropriate with explicit owner follow-up.

Comment thread docs/pages/CRISP/introduction.mdx
The walkthrough said publishInput verifies the vote proof "through the
CRISPVerifier contract". CRISPProgram holds two Honk verifiers and picks
between them by census mode: _eligibility returns honkVerifier for a Merkle
census and onchainHonkVerifier for an on-chain token census
(CRISPProgram.sol:132, :135, :588-616). The deploy script wires
verifierNames('merkle') to the first and verifierNames('onchain') to the second
(deploy/crisp.ts:76, :106), and those resolve to CRISPVerifier.sol and
CRISPOnchainVerifier.sol (scripts/verifiers.ts:22-23).

Naming only the first reads as though an ONCHAIN round uses it too.

The page describes only the Merkle path in two other places: line 95 on
eligibility, and the CRISPVerifier.sol paragraph. Covering the on-chain census
there is a separate gap and is left alone.

The publishInput bullet mixed two bases in one sentence:
contracts/CRISPProgram.sol resolves from the README's own directory, while
crates/zk-helpers/... and circuits/bin/threshold/ resolve only from the
repository root. A reader sitting in crisp-contracts finds the first and
neither of the others. Made all three repo-root relative and said so.

Both census verifiers were named as though CRISPVerifier and
CRISPOnchainVerifier were contract names. Each file declares a contract called
HonkVerifier (verifiers/CRISPVerifier.sol, verifiers/CRISPOnchainVerifier.sol),
so the files are what distinguishes them. Named them with their extensions in
both documents and said why.
