emit/seeds.rs moves to emit_seeds.nikaScore: self-hosting lane (docs/priorities.md), one of two builders’ lanes; bugs lane has #655 in the same batch. Last step of #867: its commit says Fixes #867.
crates/nikaia/src/emit/seeds.rs writes a map position’s hidden seed parameters (__S0, ADR-010 D9) into the text of a written type, and reads which pub items hold maps. Writer half done (38697bf), the Seeds tables and type queries done (6cd8fea, EmitSeedsTables). Left: the reader walks.

Commit: emit/seeds: the reader's decisions move to emit_seeds.nika with Fixes #867.If a decision cannot move because a fact type is missing in Nikaia (a syntax gap, a lowering defect), stop and report it under Found:, do not route around it.
