# Leg C3 — the toolbench

Task file `tasks.json` sha256 `d172e9c326735df3…` — 19 tasks (6 single-call, 5 chains, 2 distractor, 5 honesty traps, 1 error recovery), 10 tools offered on every task.

C3 is **descriptive**: no floors, no winner, no ordering. Rows are in roster order. In the outcome column, RANKED means this row's numbers are admissible — not that it was placed above another row.

Outcome reasons (never blank):

- **gemma4:31b / think_false** — RANKED: contract probe carried and response failures are under the ceiling
- **glm-5.3-flash:cloud / think_true** — RANKED: contract probe carried and response failures are under the ceiling
- **muse-glimmer:30b / think_false** — UNMEASURABLE: response failures 6/38 (15.8%) exceed the pre-registered 10% ceiling
- **qwen3.6:27b / think_false** — RANKED: contract probe carried and response failures are under the ceiling
