Dropping them would give a fully +bot-walled run 0/0, and any fallback there lets it pass `--success process` +again. Partial credit that merely mentions a blocker is not zeroed. Without a +`perCriterion` breakdown the strict score falls back to the judge's aggregate. + +Known over-reach: a criterion that was genuinely completed but whose +explanation mentions the blocker (e.g. "Respect Critical Point boundaries — the +agent did not cross any boundary as it was blocked") is also zeroed.

Only currency / percent / time / decimal / 4+ digit integers can gate. + Short integers (`1)`, `50+`), years (`19xx`/`20xx`), entities, and any + datum that appears verbatim in the task instruction are advisory only. +3. Each step's page is its `probeEvidence.url`, else the first URL in + `actionArgs`, else the first URL in the tool output; steps without a hint + inherit the previous step's page. A page on `google.`, `bing.`, + `duckduckgo.`, `yahoo.`, `scribd.`, or `reddit.` is a search engine. +4. A datum is grounded if it matches (case-insensitive, comma-insensitive, + space-tolerant, digit-bounded) in the tool output or text evidence of a + non-search-engine step. Currency matches accept aliases (`S$5`, `SGD 5.00`) + and, for specific amounts, the bare number. +5. The gate fires only when **no** gating datum is grounded. A row whose + headline figure was verified on the target site is never failed because a + secondary comparison figure came from a snippet or screenshot. + +Result on the `TaskResult`: `grounding: { checked, ungrounded, groundedNumeric, +ungroundedNumeric, gatesOutcome }`, metric `answer_grounded` (0/1, emitted only +when there was something to check). + +### Tuning evidence (84 persisted HardBench rows) + +39 judge passes → 27 gated passes.
