Audit the terrain alpha-mask pipeline in gillijimproject_refactor.

Requirements:

Treat commit 343dadfa27df08d384614737b6c5921efe6409c8 as the default baseline unless I specify a different one.
Read the relevant memory-bank files before drawing conclusions.
Inspect the active pipeline across Mcal.cs, StandardTerrainAdapter.cs, TerrainChunkData.cs, TerrainTileMeshBuilder.cs, TerrainRenderer.cs, TerrainImageIo.cs, and ViewerApp.cs.
Explicitly compare TerrainImageIo atlas import/export semantics against both per-chunk upload and batched tile-array packing semantics.
Distinguish decode bugs from packing bugs, shader bugs, and UI/import-export bugs.
Report findings first, ordered by severity, with concrete file references.
Then provide a minimal validation plan and the smallest high-value tests that should exist.
Do not claim the issue is resolved without real-data validation using the fixed development paths from the memory bank.

Audit the terrain alpha-mask pipeline in `gillijimproject_refactor`. Requirements: - Treat commit `343dadfa27df08d384614737b6c5921efe6409c8` as the default baseline unless I specify a different one. - Read the relevant memory-bank files before drawing conclusions. - Inspect the active pipeline across `Mcal.cs`, `StandardTerrainAdapter.cs`, `TerrainChunkData.cs`, `TerrainTileMeshBuilder.cs`, `TerrainRenderer.cs`, `TerrainImageIo.cs`, and `ViewerApp.cs`. - Explicitly compare `TerrainImageIo` atlas import/export semantics against both per-chunk upload and batched tile-array packing semantics. - Distinguish decode bugs from packing bugs, shader bugs, and UI/import-export bugs. - Report findings first, ordered by severity, with concrete file references. - Then provide a minimal validation plan and the smallest high-value tests that should exist. - Do not claim the issue is resolved without real-data validation using the fixed development paths from the memory bank.
