Go: - poly-verified-go: add Verified[T] generic wrapper, selective disclosure system (CreateDisclosure, VerifyDisclosure), error types, encryption protocol types (Mode, InferRequest/Response, MockEncryption), wire proof bridge for Rust serde compatibility - poly-client-go: thin client SDK — PrepareRequest encrypts tokens, ProcessResponse decrypts and verifies, Disclose/DiscloseRange for selective token revelation to different audiences C: - poly-verified-c: SHA-256 via OpenSSL EVP, domain-separated hashing (leaf/transition/chain/combine/blinding), Merkle trees with odd-leaf duplication, IVC accumulator (fold + finalize), selective disclosure, wire JSON serialization (integer arrays matching Rust serde) - poly-client-c: client SDK with mock encryption, JSON request/response protocol, disclosure from verified responses 297 tests across all four packages.
Three parallel jobs: cargo test --workspace, go test for both Go modules, and make test for both C modules. Triggers on push and PR.
The attack_timing_side_channel test used a 1.2x ratio threshold with only 5 trials, too tight for shared CI runners where scheduling jitter causes spurious failures. Widen to 1.5x which still catches real timing leaks while tolerating noisy environments.
When cargo test --workspace runs, poly-chain's dev-dependency enables poly-verified/mock via feature unification. This caused __macro_new to panic on Mock proofs in integration tests (cfg(test) is false for the library crate when compiled as a dependency). Fix __macro_new: only panic when mock feature is OFF (production). Fix is_verified: use cfg!(test) alone, not cfg!(feature = "mock"), so Mock proofs are only trusted in the crate's own unit tests.
The doc examples in interface/parser.rs show Poly trait syntax, not Rust code. Rustdoc tried to compile them, failing on list<i32> and string types. Mark as ```text to prevent doctest compilation.
Proc macro crate doctests cannot invoke their own macros without full crate setup. Mark all examples in polyglot-macros as ```ignore since they show usage patterns, not compilable standalone snippets.
Heavy FHE tests (10-prime chains, 8 squarings, 2048 SIMD slots) run for hours in unoptimized debug mode. Use cfg!(debug_assertions) to select lighter parameters in debug while keeping full coverage in release. CI now runs cargo test --release.
… verified poly-verified-c (248 assertions): - Cross-language hash vectors matching Rust/Go known SHA-256 outputs - Hash combine zeros vector, non-commutativity, domain separation - Hash leaf/transition/blinding domain prefix tests - Chain tests: init, append one/two, order dependent - IVC privacy modes (all 3), reject zero steps, reject missing blinding - Disclosure: range, tamper merkle, wrong root, reorder, missing, zero leaf - Verified/proof structure: is_verified, zero steps, privacy modes - Stress: IVC 100/1000 steps, private 1000, merkle 1024/odd leaves, hash determinism 10k, chain uniqueness 1000, collision resistance poly-client-c (56 assertions): - Disclosure range from response - Serialization roundtrip
poly-verified-c: +7 tests (328 assertions) — full pipeline transparent/private/disclosure integration, merkle empty/all-indices, wire JSON field validation, private mode JSON checks. poly-client-c: +4 tests (79 assertions) — client reuse, large response with disclosure, single-token edge case, NULL input safety. Fix NULL guard in poly_client.c find_json_object for NULL json input. Add test matrix to CLAUDE.md with run commands for all three languages.
