+## Batch Y input, physics, and inbound-network source-freeze replacement
+
+Batch Y converts the nine approved source-text readers in the input/physics/
+network wiring group. Seven remain as compiled-metadata architecture checks;
+two redundant source assertions are removed. No product source changes.
+
+The exact decisions are:
+
+- the ForcePosition generic-tail suite now inspects the built
+  `TryApplyGenericRemoteRenderPose` body for its one `WorldEntity.SetPosition`
+  edge and proves the committed/deferred local-position observer call is
+  immediately followed by a compiled return. The negative assertion that the
+  already-deleted `LocalForcePositionTransaction` class name was absent is
+  removed: the Runtime-owned transaction and its displaced-authority behavior
+  are already exercised by
+  `RuntimeAcceptedPositionDriveControllerTests`, while an absent identifier is
+  not behavior;
+- the contact-versus-walkability source assertion is removed. The dedicated
+  `SteepContactBody_InterpolatesInsteadOfSnapping` and
+  `FreeFlightBodyWithNoContact_StillSnaps` behavioral tests exercise the one
+  discriminating state and the opposite boundary through the real routing
+  method, so retaining a string check would add brittleness rather than
+  coverage. The AP-140 retail rationale remains beside those behavioral tests;
+- local inbound SetState routing now verifies the compiled controller graph has
+  exactly one `PlayerMovementController.ApplyServerPhysicsState` edge and no
+  direct `ApplyPhysicsState` edge;
+- the #270 movement-stats contract reflects the single
+  `StaminaExhaustionEdgeTracker` owner and follows the compiled Observe,
+  ReportExhaustion, Reset, and two factory Apply edges. Existing tracker and
+  Runtime movement-state behavior suites remain the behavioral oracle;
+- remote spawn settling now identifies both compiled call sites
+  (`DispatchRemoteInboundMotion` and `OnPosition`), verifies the repeated
+  inbound route checks `PhysicsBody.InContact` before reseeding, and verifies
+  the shared seed helper calls `SpawnPlacementSettler.TrySettle`;
+- production auto-entry readiness now follows compiled calls to the published
+  controller, live-record lookup, and physics-host view and verifies the exact
+  `EntityPhysicsHost` type operand; and
+- player presentation attachment now verifies compiled call order from the
+  animation sink assignment through matched animation drain to the unmatched
+  interpreter suffix drain.
+
+`CompiledCallGraph` gained reusable instruction and type-reference readers.
+They allow exact return and `isinst`/cast boundaries to be checked without
+making comments, whitespace, local names, or source paths part of the oracle.
+
+Verification:
+
+- the directly affected and adjacent behavioral App suites pass 31/31, and
+  the two Runtime owner suites pass 52/52;
+- the complete locked Release build covers all 44 projects with zero warnings
+  and zero errors;
+- the no-retry complete hermetic Release gate passes 14,347/14,347 with zero
+  skips or failures across all 12 test assemblies. The exact two-case
+  reduction is the two redundant source assertions above; and
+- the regenerated 1,254-file inventory parses every file, reports 11,415
+  attributed methods, and reduces total direct/helper source readers from 92
+  to 83 while direct readers remain 57. The remaining 83 reconcile to the 22
+  approved retained policies/contracts and 61 staged replacements.
