📜 WAYPOINT LESSON
Checkpoint: Ownership
⭐⭐ intermediate⏳ 22 min read📍 Lesson 96 of 225
Prove you can build a structure whose ownership story survives pushes, pops, peeks, and double destroys.
What you just proved
- Allocation-failure contracts that never leave a half-built state.
- The realloc temp-pointer discipline, amortized doubling.
- Ownership transfer (store/take/release) as explicit API vocabulary.
- A structure that frees every byte exactly once on every path.
Next module: functions as data — pointers to code, and the designs they unlock.
