The disembark probe grounds evidence/open-questions only from open issues and intents, and evidence/tradeoffs only from ADR alternatives and the decision log (internal/core/lifeboat/sources_native.go, nativeOpenQuestionsSource and nativeTradeoffsSource). Neither reads the repository's own brief file for its section (03-evidence/03-open-questions.md, 03-evidence/04-tradeoffs.md), which every other brief section's source reads, so a downstream project with both files authored saw them ignored. A partial verdict also carries no reason: Evidence fills Searched and Question only on a blank, so a section rated partial does not say what was found or what would ground it.

Grounds

• pursued: a repository with authored 03-open-questions.md / 04-tradeoffs.md and no open issues, ADR alternatives or decision log now probes those sections as grounded, citing the file, and no partial row in any probe output lacks a reason; shown wrong if TestNativeEvidenceSectionsGroundFromTheirBriefFiles, TestProbeEveryPartialCarriesAReason, TestEverySourcePartialCarriesAReason or TestPartialIsBuiltOnlyThroughTheConstructor fails, or if abcd disembark probe on such a repo still reports those sections blank or a partial without a reason.
