  "gloss": "Test a candidate carve by routing a few concrete tasks through it before it is kept",
  "mechanism": "When a {{decompose}} step proposes a candidate carve, a few concrete tasks from its domain, typically three, are generated before the carve is kept, and each is passed by {{route}} to the proposed sub-concepts. A task that finds no clean home suggests a missing dimension, and a task that belongs equally to two sub-concepts suggests that they are not independent enough. The carve is reframed until each task, or each part of a task, routes cleanly to exactly one sub-concept, or it is kept with a recorded warning; a task whose parts go to different sub-concepts is clean, while a part that could go equally to two is not. The check is empirical: it catches carves that are logically elegant but functionally weak, which the four tests, judged in the abstract, can miss.",
  "invariants": [
    "Concrete tasks from the carve's domain are routed through the proposed sub-concepts before the carve is kept.",
    "A task with no clean home, or with two equal homes, leads to a reframing of the carve or to keeping it with a recorded warning."
  ],
  "failure_modes": [
    "Tailored sample: the tasks are chosen to fit the proposed carve, so every one routes cleanly.",
    "Warning forgotten: a carve kept with a routing warning is later treated as if it had routed cleanly.",
    "Sample read as proof: a clean routing of a few tasks is taken to certify the carve."
