# K1 Kmap loader 0.6.0
Reexports `ConnectionTier`, `Node`, and `NodeId`, and exposes `OpenMode`, `LoadOrigin`, `LoadedNode`, `OpenResult`, `PREVIEW_COST` (0.3), and `NARRATIVE_COST` (1.0). `open_node` performs synchronous Full or NavigationOnly traversal with finite nonnegative budget and temperature.
Every loaded node records the exact origin of its preview. A Full narrative separately records the occurrence that opened it, so a Navigation preview later opened through an Automated edge preserves both facts. Root origins are `Root`; connection origins include the exact source node and tier. Provenance does not change filtering, scoring, selection, cost, order, or RNG behavior.
Candidate visibility is resolved in source order, cached, and applied before reads, costs, scoring, and RNG. Duplicate paths remain separate tickets whose cumulative strengths multiply edge weights. Full mode uses free root Navigation previews and two-hit preview/narrative loading. NavigationOnly atomically loads a selected preview plus visible unseen Navigation children and stops at the first unaffordable bundle.
