  "message": "Move ReflectionData and DescriptorTable out of writable .data into .data.rel.ro and .bss.\n\nPer-message `ReflectionData` (40 B) and per-file `DescriptorTable` (88 B) previously lived in writable `.data` because of mutable lazy-initialization fields, mixing relocated pointers with zero-initialized state in `.data`:\n1. Separate the two mutable reflection pointers (`reflection`, `descriptor`) into a zero-initialized `ReflectionState` (16 B in `.bss`), return `\u0026kDescriptorMethods` directly from `ClassData::descriptor_methods()`, and split `ReflectionDataWithTracker` (24 B) from standard `ReflectionData` (16 B in `.data.rel.ro`, gated by `ClassData::has_get_metadata_tracker_`). This shrinks `file_reflection_data` in `.data.rel.ro` from 40 B to 16 B per message (-24 B and -1 relocation per message) and moves the mutable 16 B state to demand-zero `.bss`.\n2. Move `DescriptorTable::is_initialized` into `DescriptorTableOnce` alongside `absl::once_flag` in `.bss` and omit `file_level_service_descriptors` from `DescriptorTable` (computing service descriptors on demand from `FileDescriptor::service(index)` via `GetServiceDescriptor`), shrinking `DescriptorTable` from 88 B to 80 B and moving it from writable `.data` to `const` `.data.rel.ro`.\n\nPiperOrigin-RevId: 1013736367\n",
