Version bumped to 5.0.0 across include/zupt.h, all packaging recipes, man
page, and docs.
Audit fixes (pre-5.0.0 review):
- src/zupt_format.c: overflow-safe bound in the solid-mode `test` path
(off+sz could wrap and drive an OOB read in zupt_xxh64 on a crafted archive;
the extract path was already hardened, the test path was not).
- gui: run_async now marshals the completion callback onto the GUI thread with
QueuedConnection (a bare functor connected DirectConnection and touched
widgets off the worker thread); Extract auto-detect note survives the log
clear via a new `info` param.
- .github/workflows/ci.yml: trigger on `master` (was main/develop, so CI never
ran); `make dist` tarball is vaptvupt-*.tar.gz not zupt-*; the ASAN PQ
round-trip uses native --pq (was --pq-sdk, which fails on the source-only
build and blocked the release job).
Documentation:
- New AUDIT.md (methodology, FIPS 203 conformance validation, findings, repro).
- CHANGELOG 5.0.0 entry covers the FIPS 203 conformance fix + BREAKING note and
the GUI/CLI/security/packaging work.
- README "What's new in 5.0.0", download tables (incl. Windows/macOS/BSD +
portable GUI), version-history row.
- SECURITY.md + THREAT_MODEL.md: ML-KEM-768 documented as FIPS 203, validated
byte-for-byte against OpenSSL 3.5.
- Accuracy fixes: man page (--kdf default is PBKDF2 on source-only; codec
2.60.4), rpm %description, debian control/copyright, homebrew header
(no vendored library on source-only builds).
make check 16/16 (FIPS 203 conformance 3/3, all distro-safe checks).
