  "message": "Optimize EncodedDescriptorDatabase::DescriptorIndex symbol indexing.\n\n1. Add transparent lookup (`is_transparent`) with `UnencodedSymbolEntry`\n   (`parts()`) to the temporary `by_symbol_` B-tree so `FindSymbol` during\n   registration does not construct a synthetic `SymbolEntry` or rescan\n   `data_`.\n2. Add a `data_offset \u003d\u003d super.data_offset` fast path in\n   `SymbolEntry::IsSubSymbolOf` before delegating to\n   `parts(index).IsSubSymbolOf(super.parts(index))`.\n3. Skip `by_symbol_flat_` binary searches in `AddSymbol` when\n   `by_symbol_flat_.empty()`, and use `flat-\u003eassign(s-\u003ebegin(), s-\u003eend())`\n   when `flat-\u003eempty()` in `MergeIntoFlat`.\n\nPiperOrigin-RevId: 988534156\n",
