App converts immutable DAT sky definitions once and projects the borrowed Runtime snapshot into rendering; no process-global Region origin or second App clock/weather owner remains (`902076c0`). TS-54/TS-55 register the remaining centered UI sound and full fog/ambient/radar behavior gaps. |

The directory owns canonical GUID/incarnation/local-ID identity, accepted snapshots/timestamps, parent state, operation versions, and tombstones. `LiveEntityProjectionStore` owns App graphical sidecars by exact `RuntimeEntityKey`; hydration, presentation components, `GpuWorldState` residence/visibility, and retryable teardown preserve that key without another authority. Exact receipts precede fallible callbacks, re-entrant commits drain synchronously in sequence, and stable reset/disposal must converge the complete ledger to zero (`f46ddb5c`, `420e5eea`, `e937cc36`, `5ef8b537`, `ce3ac310`, `119b7c11`). |

 | Action/combat/magic/movement | **J5 complete** | Runtime `RuntimeActionState` owns the exact selection, temporary target mode, interaction transactions, combat attack/target/mode, and spell-cast intent children. Interaction owns use/appraisal/pickup identity, ordered FIFO, and exact post-arrival token while borrowing J4's sole busy gate. `RuntimeLocalPlayerMovementState` owns the exact local controller, construction seam, autorun latch, typed view, and outbound MTS/jump/AP cadence.

 | Physics/remote simulation | **J5.5 complete** | `RuntimePhysicsState` owns one per-session engine, production cache/cell graph, transition scratch, shadow registry, typed collision admissions, canonical bodies/hosts/remotes, keyed ordinary/remote worksets, simulation, and cell commits. App streaming supplies immutable prepared collision; animation/shape adapters supply graphical inputs and project committed snapshots only (`7e6033d0`). |
 | Projectile simulation | **J5.6 complete** | `RuntimeEntityRecord`/`RuntimePhysicsState` own the canonical projectile component, exact-key workset, prediction/correction state, unchanged retail quantum/integration/sweep/collision loop, and cell commits. App resolves immutable Setup/DAT shape input and projects committed render, shadow, and effect-pose results only (`2aee3356`). |
 | Landblock presentation | **Complete** | `LandblockBuildFactory` owns the captured-origin DAT transaction; concrete render/physics/DAT-static publishers and `LandblockPresentationPipeline` own typed-meter publication and exact retryable retirement. `StreamingController` owns stable destination/control/unload/Near/Far queues and destination reservation. CPU mesh-cache restaging requires an exact live owner. `StreamingOriginRecenterCoordinator` serializes old-window retirement with teleport/session origin lifetimes. `GameWindow` retains construction and one pipeline field only (`c79d0a49`, closeout `4a205a3e`; Slice E closeout `91e82c3c`). |

+# Slice J6.3 — canonical teleport correlation
+
+**Date:** 2026-07-26
+**Production commit:** `6a063a27d4c805cd166d5a487afc290c34c400fd`

+
+## Outcome
+
+`AcDream.Runtime.World.RuntimeWorldTransitState` now owns the complete
+authoritative teleport-notification and accepted-destination lifetime:
+
+- wrap-safe F751 freshness and last-notification history;
+- the pending and active teleport sequence;
+- Position-before-F751 buffering and F751-before-Position matching;
+- the first accepted destination for one teleport generation;
+- exact generation, sequence, and destination-cell placement validation;
+- exact materialization acknowledgement; and
+- cancellation and session-reset cleanup without generation reuse.
+
+`RuntimeTeleportDestination` preserves the server GUID, all four relevant
+retail sequence channels, and the complete Core `Position`, including its
+cell-local frame. The App converts accepted network data once at the wire
+boundary, after canonical Runtime physics has accepted and applied the
+Position update.
+
+The former App `TeleportTransitCoordinator<T>` and duplicate accepted-
+destination state are deleted. `LocalPlayerTeleportController` now borrows
+Runtime transit truth and owns only graphical portal activation, render-space
+translation/recentering, destination placement callbacks, tunnel presentation,
+and retained UI. Login reveal and portal reveal are separate typed operations,
+so an ordinary login cannot accidentally satisfy a teleport sequence.
+
+## Retail ordering
+
+- `SmartBox::HandlePlayerTeleport @ 0x00452150`
+- `SmartBox::TeleportPlayer @ 0x00453910`
+- `SmartBox::UseTime @ 0x00455410`
+
+Retail accepts an equal or wrap-safe-newer F751 sequence, clears the local
+position-complete state, and waits for a corresponding accepted Position
+without advancing the Position timestamp itself. ACE emits the F751 and
+Position with the same teleport sequence but transport order is not assumed.
+The Runtime owner therefore supports both packet orders while keeping
+canonical physics acceptance independent.
+
+The detailed translation is recorded in
+[`2026-07-15-retail-portal-space-pseudocode.md`](2026-07-15-retail-portal-space-pseudocode.md).
+
+## Automated evidence
+
+- Runtime: 360 passed, including 28 focused transit-state tests.
+- App focused transit/reveal suite: 34 passed.
+- App: 3,710 passed / 3 skipped.
+- Complete solution: 8,631 passed / 5 skipped.
+- Release build: zero errors; 17 pre-existing test-project warnings tracked by
+  issue #228.
+- Source/ownership guards: the App transit coordinator is absent, graphical
+  composition borrows the session Runtime transit owner, and no parallel
+  current-cell or accepted-destination authority remains.
+- Adversarial fixtures: Position-before-F751, F751-before-Position,
+  duplicate/stale/wrapped sequences, supersession, exact placement and
+  materialization mismatch, mid-transit reset, reconnect, generation reuse,
+  and two-instance isolation.
+
+## Connected evidence
+
+Accepted report:
+`logs/connected-world-gate-20260726-175333/report.json`
+
+The report records exact source and embedded binary commit
+`6a063a27d4c805cd166d5a487afc290c34c400fd`.
+
+- Capped process: 244.427 seconds, six checkpoints, graceful code-zero exit.
+- Uncapped fresh-process reconnect: 61.414 seconds, one checkpoint, graceful
+  code-zero exit.
+- Route: fresh login, Aerlinthe, Rynthid world edge, Facility Hub dungeon,
+  Holtburg, Aerlinthe revisit, then fresh-process reconnect.
+- Failures: zero.
+- Reveal invariant failures: zero.
+- Expected warning: 25 instrumented world-edge landblock misses.
+
+No new retail divergence was introduced. The two-order buffer contains only
+immutable destination data that canonical Runtime physics already accepted; it
+is correlation state, not a second physics or position authority.
