Test C (deliberately malformed): artifact malformed.txt (sha256 24920671…, 47 bytes) is prose that cannot be parsed as v-lines. Exercises the unverifiable path.
Test C done: VerificationRun vrn_sn8j4vlkvc finished inconclusive — "assignment could not be parsed as v-lines: not a literal: this". Correctly distinguished from refuted. The deliverable of this Attempt was the negative test, hence outcome completed.
Deliberate negative test. The artifact is text/plain but is prose, not v-line format, and cannot be parsed as an assignment at all. Expected verifier result: inconclusive (unverifiable), per the Contract's malformed_v_lines conformance fixture — not refuted.
