  "message": "Restrict sequence locks to multi-word flags and shrink mutation counts.\n\nAny `absl::Flag` whose value fits in 8 bytes reads and writes its value atomically without consulting a sequence lock. Even so, every `absl::flags_internal::FlagImpl` in writable data previously paid 8 bytes for a sequence lock just to track modification counts for tests and flag savers.\n\nMove `SequenceLock` into the multi-word flag value storage specialization so only types larger than 8 bytes allocate it. Track mutations on `FlagImpl` with a 3-bit saturating counter inside an atomic state byte that overflows into a process-wide map after seven updates, shrinking the base object from 72 bytes to 64 bytes and scalar flags from 80 bytes to 72 bytes.\n\nPiperOrigin-RevId: 1006216187\n",
