 - Added tests for network-band rules, reactor-ready rules, inventory rules, removal effects, electricity leak access, and invalid rule targets.
 - Verified `dotnet test tests/ReactorMaintenance.Simulation.Tests/ReactorMaintenance.Simulation.Tests.csproj` passes after the rule slice: 21 passed.
 - Ran `jb cleanupcode --build=False ...` and `python D:\Code\crlf.py ...` for touched C# files after the rule slice.
+- Split serializable simulation records and enums from the monolithic `Models.cs` file into individual files under `Models`.
+- Moved level creation, grid mutation helpers, surface clamping, grid geometry, and inventory operations out of serializable model records.
+- Replaced separate T-junction and cross-junction props/tools with one topology-inferred `Junction` prop and one editor tool.
+- Moved junction ratio presets into balancing data.
+- Replaced hardcoded `EPairEffect` variants with parameterized surface interaction verbs and balance-owned magnitudes.
+- Introduced a small public `SimulationEngine` facade over an internal simulation system implementation.
+- Updated design documentation for generic junctions and parameterized surface interactions.

 ## Future Work
 
-1. Expand simulation fidelity where the first slice is intentionally simplified: complete pair table coverage and stronger forecast proof cases.
+1. Continue splitting the internal simulation system into smaller action, network, consumer, leak, surface interaction, robot safety, reactor, rule, and forecast systems.
 2. Add advanced editor workflows for explicit reactor binding selection, explicit door edge selection, electricity wall leak face selection, and rule event authoring.
 3. Verify and polish the Win2D app on Windows where the XAML compiler can run.
 4. Update README and any affected docs to reflect the new schema, .NET target, editor controls, and deterministic defaults.
