docs(runtime): close J3.3 and hand off J3.4

Record exact projection-store ownership, automated and connected evidence, rollback chain, and the executor-ready canonical object-table plan. Reconcile milestones, roadmap, architecture, divergence pointers, AGENTS/CLAUDE, and durable handoff state.

 - No new allocation appears in steady-state live-object traversal.
 - No callback is delayed to another frame.
 - All automated and connected gates pass on the exact commit.

+## Completion result
+
+All acceptance conditions pass on final exact binary `e937cc36`.
+
+- `LiveEntityProjectionStore` is the only materialized App sidecar store and is
+  keyed by exact `RuntimeEntityKey`.
+- The temporary `ActiveRecordView`, `_activeRecords`, detached App record
+  constructor, and broad materialized/visible `WorldEntity` collection
+  surfaces are deleted. Borrowed exact-key record views remain for hot
+  traversal and tests.
+- Hydration, animation, effects, lights, equipped children, remote teleport,
+  render journal, liveness, movement observations, teardown, spatial
+  residence, and visibility transitions carry the exact key.
+- `GpuWorldState` retains the exact key through loaded/pending rebucketing,
+  landblock retirement, origin recentering, quiescence, and reentrant
+  visibility delivery. DAT-static entities remain outside live Runtime
+  identity.
+- Runtime remains the only current-GUID/incarnation/local-ID authority. App
+  resolves GUID through Runtime and never decides which incarnation is current.
+- Synchronous callbacks, allocation order, render ordering, and frame timing
+  are unchanged.
+
+Evidence:
+
+- 104 focused App ownership/streaming tests passed.
+- 3,761 App tests passed / 3 skipped.
+- 8,444 complete Release tests passed / 5 skipped.
+- Release solution build passed.
+- `logs/connected-world-gate-20260725-221008/report.json` passed on exact commit
+  `e937cc36`: two sessions, seven checkpoints, two graceful zero-code exits,
+  zero failures, zero render-shadow mismatches, and zero pending deltas.
+
+Exact rollback, newest commit first:
+
+```text
+git revert e937cc36df39cf6ea1eaba2f9c0243d1929da702
+git revert 420e5eea70fd2c29cf9c8614e6298a1f84d64045
+```
+
+J3.4 is the next clean slice. It moves canonical `ClientObjectTable` ownership
+under the Runtime entity/object lifetime group without moving retained UI,
+icons, paperdolls, grids, cooldown drawing, or interaction presentation.
