Cache keys now include a schema version prefix so that world-schema
changes automatically invalidate stale cached extraction results.
Previously two incompatible schema versions would share the same
cache key if URL/selectors/env matched, silently returning stale data.
WORLD_CACHE_SCHEMA_VERSION exported publicly so consumers can
increment it when making schema-incompatible changes to extraction.
658 tests pass.
geometry-cache.ts: replace 5 empty catch blocks with console.warn
- statSync failure, rmSync failure (x2), readCachedWorld failure,
readCachedExtractionResult failure were all silently swallowed.
Now emit context-bearing warnings so stale/corrupt caches are visible.
predicates.ts: replace __boxIndex as any mutation with WeakMap
- getBorderRect used (world as any).__boxIndex to cache a subject-to-
box-index map on the world object. Replaced with module-level WeakMap
that auto-collects when the world is GC'd. Eliminates 2 as any casts.
extraction.ts: serialize materializeSemanticSelector + debug cleanup
- 3 Promise.all sites over page.evaluate changed to sequential for..of
to eliminate DOM modification race conditions.
- 2 .catch(()=>{}) cleanup blocks now use console.debug so failed
cleanup is traceable when debugging.
- resolveViewport catch now emits console.warn on zero-viewport fallback.
648 SDK + 57 E2E tests pass.
