 ## 2. Binary understanding
 
 - RTTI type descriptors: **1,924** (`Game::` 1,404, `Mars::` 194; serializable types 179)
 - Classes with recovered member layouts: **384** / 1,598 named classes `[██░░░░░░░░] 24%` — `objects/layouts.json` (serializer recovery) plus classes recovered by hand in `struct-recovery.md` + `schema-gaps-resolved.md`. Note 179 types are *serializable*; the recovery also reaches non-serializable ones, so this is not a subset of that
