Replaces the stub backend (ErrBackendNotWired) with a working byte-
for-byte NIST-compatible HQC implementation. Build tag hqc_pqclean
activates the cgo path; default builds remain stub for portability.
Vendored:
- PQClean HQC-128/192/256 clean reference C (2023-04-30 NIST
submission), public domain
- PQClean shared fips202 (SHA-3 / SHAKE)
- Per-mode/per-source shim TUs (36 total) to keep PQClean's
static helpers isolated and avoid duplicate-symbol collisions
- randombytes_shim.c wiring PQClean's randombytes() to a Go-side
io.Reader callback, mutex-protected for concurrent dispatch
Tests:
- TestKAT_HQC128/192/256 — all three NIST KAT vectors verified
byte-for-byte against META.yml nistkat-sha256
- TestRoundTrip_AllModes — keygen → encap → decap roundtrip,
shared secrets byte-equal in all 3 modes
- TestDeterminism_AllModes — same seed produces identical ct/ss
(load-bearing for the precompile's on-chain determinism)
- -race clean
Correction: ciphertext sizes updated from 4481/9026/14469 (older
HQC round-3 listing) to PQClean's 4433/8978/14421 (2023-04-30 NIST
submission); the prior numbers would have failed round-trip with
a 48-byte mismatch.
