Five tests in StreamingControllerPriorityApplyTests passed only when a
sibling ran first in the same process. Run alone, they failed on
assertions about world-state residency and completion backlog:
DungeonCollapseBeforePromotionBase (line 355),
InFlightNearLoad_DemotedBeforeFirstCompletion (536),
HardRecenter_RejectsOldOverlappingLoadAndUnloadGenerations (582),
HardRecenter_DropsStaleOutboxThroughBoundedAdmission (626), and
DeferredCompaction_ApplyFailureRetainsExactResult.
The state a sibling supplied was not data. It was compiled code.
StreamingController meters each Tick against a wall-clock ceiling and
StreamingWorkBudgetOptions.Default allows 2 ms per frame; these tests
took that default. A cold first Tick has to JIT the whole publication
path, and the meter's own diagnostics measured it at 10.55 ms with
LastLimit=Time and one yield at stage publication-spatial-commit. The
frame's first operation is admitted unconditionally through
ensureProgress, so applyTerrain ran and the terrain assertion passed;
the very next reservation, the GpuWorldState spatial commit, was
refused, so the landblock never became resident in that frame. Any
sibling that publishes a landblock first (DuplicateNearCompletions, for
instance) warms that path and the same Tick then fits inside 2 ms.
Pairing the failing test with that sibling passed; pairing it with
DestinationReservation_StaleGenerationCannotClearReplacement, which
drains no completions and therefore JITs nothing, still failed.
Yielding mid-publication and resuming next frame is correct production
behavior and other tests in this file assert exactly that. The defect
was the setup: these tests assert which results publish, in what order,
and under which generation, yet left the elapsed-time dimension at a
value that made every assertion a function of machine speed and test
order. Every controller in the class now takes a budget whose time
ceiling cannot bind, applied uniformly so the next test added here does
not reacquire the dependency. Count and byte ceilings keep their real
values, including the deliberately small MaxCompletionAdmissions of
ForceReloadWindow_DiscardsBufferedCompletionsFromOldWindow and the
MaxCompletionsPerFrame scaling of the two tests that use it, so the
bounded-admission behavior under test is untouched. No assertion was
relaxed and no production code changed.
All fourteen tests in the class now pass individually and together;
Core is 3295 passed / 2 skipped, and two consecutive full-solution
Release runs are 8826 passed / 5 skipped.

Join destination scheduling to the canonical reveal generation, protect its share across every typed frame-budget dimension, and prevent stale work from clearing a replacement reservation. Remove forced incomplete materialization and project retail's centered portal wait cue while the authored tunnel remains active.
Tests: Release build clean; 91 focused reservation/reveal tests; full solution 8,158 passed, 5 skipped.

Publish the retail blocking-for-cells edge before deferred recenter work, freeze old-world presentation/simulation/audio, and advance full-window retirement from exact metered entity and owner cursors. This removes synchronous portal teardown without allowing retained owners to remain observable.
Replace RemoveAt(0)-in-a-loop drain idiom with RemoveRange(0, i) in both
Step-1 deferred drain and the post-found deferred drain inside DrainAndApply,
making each an O(N) single shift instead of O(N²) on the render-thread hot path.
Add PriorityNeverArrives_noThrow_noLoss_noDoubleApply test: sets a priority id
that never appears in the outbox, ticks several times, asserts no throw, no
loss of the non-priority completions, and no double-apply (applied count ==
completions enqueued). Comment above the priority-hunt explains the failure
mode: completions relocate to _deferredApply while the hunt is active and drain
at per-frame budget until the caller clears PriorityLandblockId.
Restyle test 2 to use named constructor arguments and break the compressed
lambda onto readable lines (matches test 1 style).

Adds PriorityLandblockId (uint, default 0) + _deferredApply buffer.
DrainAndApply now: (1) applies up to budget from the deferred buffer,
(2) when PriorityLandblockId != 0, hunts the worker outbox in chunks
applying the priority LB immediately on match and buffering any
non-priority items drained past it for later frames,
(3) falls back to normal drain when no priority is set or not found.
Extracts ApplyResult(result) + ResultLandblockId(result) helpers so
both the priority and normal paths share identical side-effects.
No existing behaviour changes on the non-priority path.
21 streaming tests pass (19 existing + 2 new priority-apply tests).
