Adds p3q/ct/dudect/ (constant-time test harness for P3Q precompile), parallel to the existing mlkem/ct/dudect/. Moved from ~/work/lux/precompile/p3q/ct/dudect/ as part of the "keep precompile light, import crypto" cleanup. Files: dudect_compat.h, dudect_verify.c, verify_ct.go, Makefile, fetch.sh, run-submission.sh, README.md. The verify_ct.go cgo bridge is build-tag-gated (p3q_verify_ct) and has no public Go imports, so moving the file path is safe.

# P3Q constant-time analysis harness — dudect bridge.
|
|
#
|
|
# Builds the cgo shim library (libp3q_verify) and links the C dudect
|
|
# harness against it.
|
|
#
|
|
# Prereqs (run once):
|
|
# ./fetch.sh # pulls dudect.h at the pinned commit
|
|
#
|
|
# Build:
|
|
# make
|
|
#
|
|
# Run:
|
|
# ./dudect_verify # smoke test (10000 samples/batch x 4 batches)
|
|
#
|
|
# Full submission run (10^9 samples on a pinned-CPU quiet host):
|
|
# DUDECT_SAMPLES=1000000 DUDECT_MAX_BATCHES=1000 ./dudect_verify

# Hosts:
|

# - x86_64 Linux/macOS: builds cleanly against upstream dudect.h

# - aarch64 Linux/macOS: dudect_compat.h is force-included to supply
|
|
# ARM equivalents of _mm_mfence() / __rdtsc(); see header for the
|
|
# accuracy disclaimer.
