Current-content Unity 6.6 port, 17 September 2026

This is an engine/package/API port of the current game content, not an engine-binary-only change and not the old Rampage66 project. No Editor, build or GPU workload was launched by the preparation agent. After the pre-import delta was frozen, the root agent launched the build described below.

Provenance and unchanged content

• Source: C:/Unity Projects/MotoRacer - Rampage.
• Destination: C:/Unity Projects/MotoRacer - Rampage/Tools/Diagnostics/CurrentContentUnity66-20260917.
• Baseline: current-content-snapshot.json, 1,116 copied files in Assets, Packages and ProjectSettings; full copies without hard links. All original source file SHA-256 values were rechecked after the port and still match the snapshot.
• Every changed/deleted/added file is listed below. All other copied files still match the snapshot, including scenes, meshes, textures, shaders, settings and authored track data. No files or package lock from the old Rampage66 were used.
• Editor: C:/Unity Editors/6000.6.0f1/Editor/Unity.exe, the complete short-path installation.

Deliberate changes

1. Manifest: HDRP 17.3.0 -> 17.6.0, uGUI 2.0.0 -> 2.6.0. Other direct pins unchanged. Installed HDRP 17.6 requires Core, ShaderGraph, VFX Graph and HDRP Config 17.6. The copied lock was removed so this Editor resolves its dependency graph. Record the regenerated lock: Unity 6.6 also supplies built-in Cinemachine/Collections 6.6.0, Burst 2.0.0, Mathematics 1.4.0 and Test Framework 1.8.0; their actual resolved versions are not assumed to stay at older manifest pins.
2. Exactly 15 obsolete GetInstanceID() calls in ten current C# files were ported. Direct metadata inspection of the installed 6.6 CoreModule proves both GetInstanceID and implicit EntityId/int conversion are Obsolete(error=true).
3. Full EntityId values remain in identity-sensitive comparisons: terrain/wall caches, particle/audio emitter tie-breaking and material batching keys. Hashes are used only for existing 32-bit random/audio seeds and legacy numeric diagnostic fields. Those hash fields are not collision-free identity proofs. Audio seed values and deterministic tie order can differ between engine versions; they are not promised bit-identical.
4. Added clone-only Rampage.Editor.CurrentContentUpgradeBuild.Run and meta. It invokes the existing private BuildPlayer method, without Configure, Bootstrap rebuilding or authoring bakes. Guards require the exact snapshot path, Unity 6000.6.0, an explicit opt-in flag/output and unchanged explicit DX11/DX12 API order. Existing BuildPlayer verifies Both Forward/Deferred support and writes its ordinary build manifest. The sourceCommit field is populated with snapshot-sha256:<baseline manifest hash> rather than falsely implying a clean Git commit.

ProjectVersion.txt is deliberately unchanged before import; Unity will migrate it in the copy. Record any additional importer/settings changes after first import. The current HDRP asset is already Both=3 and the player settings already specify DX11 followed by DX12, automatic selection disabled.

Root-owned build invocation

Root launched this invocation at 2026-09-16 23:38:44 UTC / 17 September 01:38:44 CEST, PID 43492, after reviewing the frozen port. Source: build-launch.json. The preparation agent did not launch it or edit the snapshot while this build runs. Unlike the earlier proposed invocation, the actual invocation omits -nographics.

& 'C:/Unity Editors/6000.6.0f1/Editor/Unity.exe' -batchmode -quit -projectPath 'C:/Unity Projects/MotoRacer - Rampage/Tools/Diagnostics/CurrentContentUnity66-20260917' -executeMethod Rampage.Editor.CurrentContentUpgradeBuild.Run -rampageCurrentContentUpgradeBuild -rampageBuildOutput 'C:/Unity Projects/MotoRacer - Rampage/Builds/Windows-CurrentContent-Unity66-20260917' -logFile 'C:/Unity Projects/MotoRacer - Rampage/Docs/QA/20260917-user-crash-61088/unity66-build.log'

Static verification: no GetInstanceID calls remain in copied Rampage C#; identity fields use EntityId without deprecated integer conversions; source hashes match baseline. Full C#/shader/import validation is pending the root-owned Editor build. No successful compile or runtime result is claimed here.

Exact pre-import delta

Baseline manifest SHA-256: 9FCFA4CBE8B7C4333BD1709FD92220736C81AC749572BFD88185B895416DAE67.

Observed first-import package resolution

Read at 2026-09-16T23:41:11.7468220Z while the root-owned import was still running. This is the actual regenerated lock, not a guessed dependency list. Lock SHA-256: 013EB45370F95D2ED268F734F0FF88F44E55316410A2871175AA6F560BFE573C. Input System 1.20.0 and Splines 2.9.1 are unchanged. Recheck after the completed build before treating the import delta as final.
