assertCoverableCoastMask
assertCoverableCoastMask(
edges,context?):void
Defined in: packages/declarative-hex-worlds/src/selectors/selectors.ts:281
Assert that edges form a coverable coast mask, throwing a clear author-time
error otherwise. Called by GameboardBuilder.setCoastEdges so a bad mask fails
at the authoring call — naming the tile + the offending mask — rather than deep
in projection with an opaque “no coast variant covers …” runtime error.
