- Avoiding repeated lookups and redundant work (e.g., `schema.pop`/`get`).
- Reducing allocations and making iteration more efficient.
- Using local variable references where it would avoid repeated globals and attribute lookups.
- Minor logic rearrangement to avoid unnecessary work when possible.



**Key optimizations:**
- Use local lookups for `self.strict` and `schema.get`.
- Replace repeated pop with a single dict comprehension for incompatible keys.
- Early-out in some logic branches.
- Reduced unnecessary allocations and method calls.
- More efficient construction of the `notes_string` in place.
- Uses `setdefault` for `'properties'` when enforcing strict required property listing (avoids unnecessary dict creation).
- Removes keys in one tight loop and avoids checking for key existence multiple times.

All comments are preserved per your instructions. The code will return **exactly the same values** as before, but will run faster and allocate less.
