Shipped defect in route 2 (9966b531), found while reviewing route 4a.
`InboundPhysicsStateController.TryApplyPosition` built its AcceptedPhysicsTimestamps
via `Current(gate, teleportAdvanced: ...)`, omitting `previousTeleport`, which
defaulted to a literal 0. The only site that populated it was the deferred
initial-create path — which is why the continuation executor was correct and
every newer consumer was not.
Consequence in shipped code: route 2 feeds this into
`ValidAcceptedAuthority`, which requires Previous == Accepted for a
ForcePosition. Any local player whose TELEPORT_TS is nonzero — anyone who has
portalled or recalled this session — had the authority rejected and the force
correction SILENTLY DROPPED. The user's @pklite acceptance was genuine but
narrow: that character had not teleported, so the stamp was still 0.
Second latent consequence: with an accepted stamp >= 0x8000, wrap-safe
TeleportRegressed also fires against the 0 and rejects ordinary Apply positions,
not just ForcePosition.
The fix captures `previousTeleport = gate.TeleportTimestamp` BEFORE
`TryAcceptPositionEvent` mutates it, matching the shape the deferred path
already used. Ordering is the whole point: capturing after would make
Previous == Accepted unconditionally, so ValidAcceptedAuthority's check would
pass vacuously — the symptom would disappear while the semantics broke.
Also removes the footgun that allowed it. `Current`'s parameter is now
`ushort? previousTeleport = null` resolving to `gate.TeleportTimestamp`, so the
eleven non-Position channels — none of which can move TELEPORT_TS — get
"previous == current" by omission rather than a literal 0 that is
indistinguishable from a genuine "never teleported".
Consumer audit: only TryApplyPosition was defective. The two route-2 call sites
trace back to it; the RuntimeEntityObjectLifetime sites source from
TryAcceptDeferredPosition and were already correct.
Tests discrimination-verified by reverting the argument to 0: the stamp test
fails Expected 10 / Actual 0, and the classifier test fails Expected
SetPositionSimple / Actual RejectedAuthority — the shipped defect reproduced
exactly.
Gates: complete Release solution 10,935 passed / 4 skipped / 0 failed.

The admission checkpoint (30012361) sealed accepted updates behind a
pending initial placement; nothing could apply them, so AcknowledgeAdoption
refused any non-empty FIFO and the residence system had no path to
completion. RuntimeInitialCreateContinuationExecutor is that missing
mechanism: a synchronous, retry-idempotent Execute transaction that adopts
the acknowledged initial placement exactly once (consuming the retained
completion so later authored placements for the key can begin), emits the
AfterEnterWorld hook request for the local player, replays deferred
missing-parent raw Creates and queued parent relations by parent GUID
(retail ProcessObjectNetBlobs order: whole-bucket detach, FIFO dispatch,
cancellation-aware restore), and drains the mixed continuation FIFO
strictly by sequence with retail route decisions taken at execution time
via ClassifyAcceptedPosition on live inputs (server-asserted wire contact,
data-driven animation proxy, live distance/options).
Apply bodies are shared with the legacy fused paths through new gate-less
instance seams on InboundPhysicsStateController that keep the one snapshot
store in lockstep; SameIncarnationCreate envelopes apply atomically with
per-stage idempotency and buffered publication after the final stage;
every abandonment path retires the residence through the lifetime choke
point and converges the ownership ledger (executor progress, deferred
buckets, replay windows, placement watches all folded into IsConverged).
Position/placement side effects are exactly-once under retry, external
mutations are detected via a field-masked executor baseline, and
AwaitingContinuationPlacement yields keep the FIFO head retryable.
Production routes are deliberately untouched: graphical and headless
Create still use legacy RegisterEntity, and no host calls Execute. The
cutover is the next checkpoint; AP-1/AD-1 remain open until it lands.
Register rows AD-59/AD-60/AP-130/AP-131/AP-132/TS-62/TS-63 document the
slice's deviations in this commit.
Reviewed: retail-conformance PASS + architecture/adversarial PASS after
five implementation rounds (wire-contact source, snapshot lockstep,
WeenieDescription merge, abandonment convergence, reentrant retirement
windows, acknowledged-completion leak, baseline precision, replay
containment/restore, queue-by-parent-GUID relation deferral all fixed at
root cause). Runtime tests 903/903; complete Release solution 10,696
passed / 4 intentional skips; focused executor gate 161/161.

Move the presentation-free inbound physics timestamp/snapshot authority and parent-relation state into AcDream.Runtime.Entities without changing their control flow. Move their dedicated tests with them and keep App consumers as borrowers during the staged J3 cutover.
Validated by 26 focused Runtime tests, 232 focused App tests, the Release solution build, and 8,429 complete Release tests with five existing skips.
