Finite-trace verdict semantics (RFC-049) — Direction 4 of the RFC-047 research agenda — plus the documentation and site restructure around the six bug classes.

Changed

  • Timeout is always INCONCLUSIVE, never PASS. A test() that ends by hitting its timeout now finalizes INCONCLUSIVE even if every eventually() it declared was satisfied before the deadline. The body did not reach a declared completion (natural return or terminate_when=), so the run is a truncated prefix and a green verdict would over-claim. Long-running / reuse=True specs that want a definite PASS must declare terminate_when=. Legacy synchronous def test_*() functions are unaffected.
  • Unbounded always(p) under timeout is INCONCLUSIVE. A never-violated unbounded safety property (no between=) finalizes INCONCLUSIVE on timeout (LTL₃ prefix); at natural completion or terminate_when= it stays a definitive PASS (LTL_f). Bounded always(p, between=(a,b)) is unchanged.

Added

  • vacuous_property warning event. When an always(p, between=) start anchor never fires, the window never opens and the predicate is never evaluated. The verdict stays PASS (the window may be legitimately untriggered), but the runtime now emits a vacuous_property event so a typo'd or misnamed anchor surfaces instead of hiding as a silent green.

Docs

  • Tutorial Part 1 reframed to the bug-class + boundary story; new Seeding Data & Initial State guide; new checkout Kafka outage use case; fault-level guidance in choosing-fault-levels.
  • RFC-048 (causal-guided exploration) and RFC-050 (gray/metastable faults) added as drafts; RFC-049 marked Accepted.

Verification: full host suite + go test ./testops/... -race + go vet green; Lima sweep 21/21 PASS across the 6 integration spec suites (binary, container+proxy, mocks, Kafka fd-passing, MySQL). See CHANGELOG.md.
