feat: v0.13.0 — adversarial inputs (fuzz, proptest, OS matrix) - #33
Merged
Conversation
REQ-FUZZ-001/PROP-001/MATRIX-001 verified. - 5 cargo-fuzz targets on the untrusted parsers; PR smoke + nightly. First run found a real bug: leading-zero patch ids (2026.07.052 == 2026.07.52 as identities) — fixed, regression-seeded, clean past 1.6M - proptest: round-trip, rollback monotonicity, advance-never-lowers, platform totality - CI: linux+macos matrix, MSRV 1.89, llvm-cov advisory evidence - Kani split to REQ-KANI-001 (v1.0) — not over-claimed here Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019TNtfRjLNhEz82G2ggeeNu
…locked) The lock predated the proptest dev-dep; the --locked MSRV build failed on the stale lock (not an MSRV violation — deps need 1.88, we pin 1.89). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019TNtfRjLNhEz82G2ggeeNu

The v0.13.0 slice of the roadmap. Fuzzing found and fixed a real layer-id canonicalization bug (leading-zero patches = duplicate identities) on its first run; proptest covers the core laws over the whole input space; CI now tests linux+macos with an MSRV build and coverage evidence. Kani honestly split to REQ-KANI-001 (v1.0). 82 verification-evidence steps audited.
