Introduce LiveEntityRuntime as the canonical owner of each accepted server-object incarnation, stable local identity, timestamped state, parent relations, runtime components, and exactly-once teardown. Split logical registration from rebucketing so pending landblocks, equipment attachment, pickup re-entry, and GUID replacement reuse the same entity and effect owners.
Keep canonical materialized and visible target/radar views distinct, preserve retail leave_world versus exit_world semantics, gate root simulation while cell-less, and track transitional pre-Create F754 owners through delete and session reset. Remove stale-spawn rehydration and make GpuWorldState spatial-only for live objects.
Add lifecycle, generation, pending, unload, attachment, event-publication, local-ID, rollback, and effect-cleanup coverage; update architecture, milestones, memory, and the divergence register.

Carry one complete cell payload with each streaming completion and publish visibility, physics, and render state on the render thread. Remove the obsolete post-readiness login reload that triggered a duplicate dungeon build.

Replaces the single-radius Tick with a two-tier model that consumes
StreamingRegion's TwoTierDiff (5-list) and routes to the appropriate
JobKind:
- ToLoadFar -> _enqueueLoad(id, LoadFar)
- ToLoadNear -> _enqueueLoad(id, LoadNear)
- ToPromote -> _enqueueLoad(id, PromoteToNear)
- ToDemote -> _state.RemoveEntitiesFromLandblock(id) on render thread
- ToUnload -> _enqueueUnload(id)
Drain switch handles Loaded (terrain + entity layer), Promoted (entity
layer only -- terrain already loaded), Unloaded, Failed, WorkerCrashed.
Constructor signature: nearRadius/farRadius separate ints. Old single-
radius ctor removed; existing single-radius tests updated to pass
nearRadius=farRadius for backward-compat coverage.
GameWindow's enqueueLoad lambda updated from (id =>...) to (id, kind) =>
to match new Action<uint, LandblockStreamJobKind> signature; radius: arg
renamed to nearRadius:/farRadius: (both set to _streamingRadius until T16
wires the full two-tier env-var parsing).

Code review on T10-T12 bundle (commits 0cf86bb/00bb030/0405947 + audit
fix 76e1a64) found 3 Important issues:
1. LandblockStreamer.Start() had an idempotency race — the XML doc
claimed thread-safety but the implementation checked _worker != null
before assigning, allowing two callers to both pass the check and
spawn duplicate worker threads. Fixed via Interlocked.CompareExchange.
2. No test verified the worker emits Failed when buildMeshOrNull returns
null. Added Load_WhenBuildMeshReturnsNull_ReportsFailed.
3. StreamingControllerTests.cs:81 used MeshData: default! when
constructing a Loaded result. If a future test flows MeshData
through the apply callback, the null reference would NRE rather
than producing a meaningful assertion failure. Replaced with a real
empty LandblockMeshData instance.

Replaces the T7-temporary default! MeshData placeholder. Streamer
now takes Func<uint, LoadedLandblock?, LandblockMeshData?> at
construction; the worker calls it after _loadLandblock succeeds and
passes the pre-built mesh into LandblockStreamResult.Loaded.
GameWindow's buildMeshOrNull factory takes the already-loaded
LoadedLandblock (lb.Heightmap is the LandBlock dat object), so no
additional dat read is needed — _heightTable and _blendCtx are
read-only after init, _surfaceCache is ConcurrentDictionary (T9).
Zero dat lock needed inside the mesh-build closure.
StreamingController._applyTerrain delegate signature widened to
Action<LoadedLandblock, LandblockMeshData> so the pre-built mesh
flows render-thread-side via the Loaded result. ApplyLoadedTerrainLocked
now accepts meshData and calls _terrain.AddLandblock directly, skipping
the per-frame LandblockMesh.Build that previously ran on the render
thread (~5ms per LB at radius=12 first traversal).
StreamingControllerTests updated: all four applyTerrain lambdas
adapted to the two-arg Action signature.

Extends the Loaded result record with a LandblockStreamTier discriminator
and a LandblockMeshData payload (default! stub — T13 wires the real
off-thread mesh build). Adds the Promoted variant for Far→Near upgrades
that only need the entity layer, not a mesh rebuild.
LandblockStreamer.HandleJob passes Tier.Near + default! MeshData at the
existing synchronous load site; StreamingControllerTests updated to
match the new positional signature.

Called once per frame from OnUpdate. Owns a StreamingRegion and uses
delegates into LandblockStreamer + a terrain-apply callback so unit
tests can inject fakes. Handles first-tick bootstrap (whole window
loads), boundary recenter (diff against previous center), and
drain completions (up to N per frame to cap GPU upload spikes).
4 new tests, all green.
