Deep dive (this session) eliminated the 2026-06-20 hypotheses for #138
(server objects + own avatar not showing after a teleport-out):
- NOT the Tier-1 classification cache: re-created live entities get a fresh
monotonic Id (_liveEntityIdCounter++), so the cache (keyed on Id) is always
a miss for them. (Side-finding: the cache has a real demote-vs-unload
invalidation asymmetry — RemoveLandblock doesn't fire _onLandblockUnloaded
while RemoveEntitiesFromLandblock does — but it's NOT the #138 cause.)
- The render path is fine when entities are present (login: [dyn] dyn=54
drawn=33; the dynamics partition + DrawDynamicsLast draw them).
- The actual cause: re-delivery is unreliable. notan/+Je walk-around run after
teleport-out: live:spawn doors=0, [ent]+ door appends=0, [ent-flat] server=1
— the server delivered ZERO Holtburg objects on return; they never reach
acdream. acdream unloads them on teleport-IN (the collapse) and nothing
restores them; ACE doesn't reliably re-broadcast. "Other clients see +Je"
confirms it's acdream's local world, not server state.
Fix direction (next session): re-hydrate GpuWorldState from the retained
ClientObjectTable on AddLandblock instead of depending on an ACE re-broadcast
(or treat in-range server objects as persistent across the collapse). Entity-
lifecycle/protocol change, best started fresh.
Diagnostic scaffolding (probes + the unrelated cache-asymmetry fix) reverted;
tree is back at the green #145 state (a15bd3b).
