Precomputed file categories retain only the first matching classification, so generated tests and similar overlaps lost ranking penalties after the indexing optimization. Compute independent ranking flags alongside the category before skipped content is discarded, keeping ranking cheap without having to reconstruct classifications later. The flags fit in existing Document padding on amd64 and are only needed for initial shard ordering. Keep the persisted category and index format unchanged: merge and explode preserve stored categories and relative document order rather than re-ranking reconstructed documents.

April’s indexing optimization (#1036) reused a single precomputed category for ranking, losing overlapping penalties such as generated tests. Compute independent rank flags alongside the category before discarding skipped content, keeping ranking cheap without growing Document on amd64.
The index format stays unchanged. Merge/explode retain stored categories (as fixed in #1073) and document order; regression tests cover that round trip and skipped-content handling.
