  "what_this_is": "Ten real tools — files, search, math, dates, a database, a rate-limited web endpoint, a scratchpad — offered on every task; nineteen tasks spanning single calls, three- and four-step chains, deliberate distractors, five no-tool-needed honesty traps and one injected error. Every task's expected calls are checkable predicates over what the model actually called, not a judge's opinion of it.",

    "grounded": "task_success_grounded counts tasks that passed AND made every pre-registered call. The gap between the two fields is the tasks a model got right without using the tool it was supposed to use — right answer, wrong method, and the two fields exist so that difference cannot hide.",

    "spurious_calls": "Calls the task did not need, over ALL tool calls the arm made across all 19 tasks and both repeats. The denominator is tool calls, not tasks, so a chatty arm and a quiet one are compared on the same axis. Wilson 95% intervals ride beside the rate.",
    "honesty_traps": "Five tasks whose honest answer needs no tool at all. A pass means the model declined to invent a figure; reaching for a tool is not itself a failure, asserting an unfounded answer is.",
    "outcome_states": "RANKED = the pre-probe carried and response failures are under the 10% ceiling. UNMEASURABLE = response failures above it — the numbers stand in the table and are not admissible as a score. NOT-CARRIED = the pre-probe produced no parseable tool_calls in any posture; the row's task attempts are published anyway, with the raw emission, because 'could not use the tools' and 'could not do the work' are different findings.",
    "preprobe_economics": "Two calls per arm per posture before any task ran. The REGISTERED budget is four — two postures — and the MEASURED cost of this arc's one NOT-CARRIED finding was TWO, because that arm registered one posture. Two calls and an honest row, instead of eighty scored calls and a table of zeroes that reads like a capability finding.",
    "tie_language": "Differences under two tasks read TIED (PREREG-C3). On task success that puts six arms in one top band, 16 to 15 of 19, and no ordering inside the band is claimable — which is why no row in this table carries the gold highlight."
