    "Every `target` value names the release in which the change LANDS, not the directory it is documented under. The official upgrade-guide directory name is the version at which the break was authored: docs/upgrade-guide/v0.2.1-alpha.1/ describes what the NEXT release removes.",
    "`confidence` is the honest state of the evidence. `documented` = stated by an official upgrade guide or a source-verified first-tag search. `inferred` = derived from a document but not stated as a rule. `unknown` = the knowledge base does not establish it; consumers MUST treat `unknown` as 'cannot answer', never as 'no'.",
    "`targets` is the corpus a scanner must inspect to find a violation. It is a hint, not a guarantee: a scanner that cannot resolve the target must report `unknown`, not `pass`. This mirrors the verdict discipline in guide/family-toolchain.md §2.1, where an unevaluated check must never be rendered as a pass.",
    "Detectability is limited. A change that only breaks at runtime for a given configuration cannot be proven by static inspection, and a data-loss hazard cannot be detected at all. Those records carry `detectable: false` plus the reason, so no consumer can quietly upgrade them to a pass."
