Same-session follow-up: user confirmed the light-carrier hydration fix
worked, then reported missing candle flames + fountain water particles.
Tested whether it's the same root cause (a mesh-empty Setup dropped by
EntityHydrationRules before its Setup.DefaultScript — the ambient
particle script GpuWorldState.cs:221 fires — is ever read). Refuted: the
fountain (0x02000AA3) has a surviving mesh part and a real DefaultScript
(0x33000B21), never dropped by the gate. The guessed "candle" objects
(0x02001967, ring of 16 around the fountain) have real mesh and no
DefaultScript at all — not candles. Separate root cause; filed as its
own issue rather than chased further this session.
