Replace undefined signed shifts in SPHlib SIMD FFT arithmetic with bounded multiplications, handle empty vectors in base64/base32/base58/hash/script paths, and skip the DoS_checkSig microbenchmark threshold under sanitizer instrumentation.
Sanitizer ctest is now green locally, so make the GitHub sanitizer job blocking again.
Documents:
- V5 soft-cap test coverage shipped on audit/kernel-coverage (ab0f4b4)
- PR #14 CI status: test-linux-unit PASS, sanitizer FAIL pre-existing
(simd.c:265 UBSan, separate workstream)
- Outstanding work prioritized for future sessions
- PR #14 is ready to merge
Documents:
- Hermes's 2026-07-04 handoff letter had a stale 'blocked on W2' framing;
W2/H4/W1 were already committed as 6cadf7f on 2026-07-02.
- This session's DoS_checkSig timing fix (commit b79e2b8): replaced the
nonsensical nManyValidate < nOneValidate comparison with a stable
per-verify bound (min of 3 trials after warmup, threshold 600ms
calibrated to ~1.6x observed p100 on DNS2).
- PR #14 CI status: 9 jobs in progress as of session end.
