Luau Roblox Optimizer

Review checklist for scripts that live inside Roblox Studio. Every item names the symptom, the cause, and the one-line fix. Studio-only means: no external tooling, no file layout advice, no --!strict lectures. Script Analysis, the Output window, the Developer Console (F9), and MicroProfiler (Ctrl+F6) are the whole toolkit.

Review output

A review IS, in this order:

1. Exploits and data loss - anything a client can abuse or that drops saved data.
2. Crashes - nil indexes, races, errors that stop the script.
3. Leaks - connections, threads, and tables that outlive their owner.
4. Performance - work done more often than needed.
5. Animation and DataStore hygiene - the two areas below.
