Three CWE-407 defects +confirmed — two in the module system, one in the compiler. Notably, the engine's own +source has `// TODO: optimize` comments at the defect sites, acknowledging the problem. + +**angelscript-0001/0002 — FindNewOwnerForSharedType/Func() (HIGH)** + +`sdk/angelscript/source/as_scriptengine.cpp:880–960` — when a module is discarded, +the engine searches all remaining modules to transfer ownership of shared types/functions. +`asCModule::FindNewOwnerForSharedType()` and `FindNewOwnerForSharedFunc()` call +`sharedTypes.IndexOf()` / `sharedFunctions.IndexOf()` — O(n) linear scan on +`asCArray` — 5 times per shared type transfer. +The engine's own comment at line 917: `// TODO: optimize: If the modules already stored the shared types separately, this would be quicker`. + +Fix: Add `asCSet sharedTypeSet` shadow; `IndexOf` → `Exists()` (O(1)). + +**Proof:** 3,980,000 ops → 39,800 ops. **100× op reduction.** + +**angelscript-0003 — CompileSwitch() case dedup (HIGH)** + +`sdk/angelscript/source/as_compiler.cpp` — during switch-statement compilation, +duplicate case values are checked via `caseValues.IndexOf()` inside a while loop. +O(n²) over the number of case values — O(n) scan per case, O(n) cases. + +Fix: Add `asCSet caseValueSet`; `IndexOf` → `Exists()` (O(1)). + +**Proof:** 124,750 ops → 500 ops. **250× op reduction.** + +All three: **PATCHED.** Patches at `defects/angelscript/patch/`.
