{"_meta": {"battery": "5f", "sub_battery": "falsification", "version": "v1", "task_count": 12, "notes": "#000046 — HARD live-path Falsification tier. Every fixture is a near-miss: the claim is FALSE / unsupported, so the correct verdict is UNGROUNDED, and that is what `expected_reason` records. As of #000048 step 2.1 (2026-05-11): #000046's paraphrase numeric-agreement gate catches the 2 magnitude/year over-grounds (50-vs-100, 300-vs-300,000) AND #000048's entity salient-token-disagreement gate catches the 4 HYBRID_ENTITY over-grounds (Insulin/Berlin/1889/Pacific — single short sentence, lone non-clustered proper-noun match, a >4-char capitalized token or number the source lacks) → all 6 now correctly land UNGROUNDED. The remaining 2 over-ground via paraphrase token-coverage on a recombined-no-number claim (\"Mercury is the largest\" vs source \"Jupiter is the largest; Mercury is the smallest\" — all content tokens present, just recombined → STRICT_PARAPHRASE; #000048 step 2.2 is the sequence-aware match that closes those). The other 4 the verifier always handled correctly. Rate at HEAD = 10/12 = 0.833 — a real below-ceiling baseline. verify_quotes is pure-lexical / deterministic, so the rate is stable. NOT part of `make bench-5f`, `make bench-5s5t5f`, `bench-fork-baseline`, or `runner --all`; pinned separately via `make bench-fork-baseline-hard`. Pre-documented gap this builds around: 5f-fal-live-003 in falsification-live-v1.jsonl. See tickets #000046 (closed) + #000048."}}
