Session 1: Initialize Trellis project guidelines
Date: 2026-08-03
Task: Initialize Trellis project guidelines
Branch: main
Summary
Initialized Trellis project scaffolding and replaced the incorrect frontend spec templates with project-specific pipeline, Blender, preview, config, and cross-layer guidance. Verified spec layers, placeholder cleanup, key-contract coverage, and Blender pure Python tests.

Session 2: Refactor Cesium material export contract
Date: 2026-08-03
Task: Refactor Cesium material export contract
Branch: main
Summary
Moved Cesium material export overrides into catalog-backed material contracts saved as Blender material custom properties. Kept legacy name-table fallback for old .blend files, updated Blender/spec guidance, and verified with unit tests, py_compile, diff check, and parity before/after comparison showing only expected cesium_export blend property diffs.

Date: 2026-08-03
Task: Extract fountain module
Branch: main
Summary
Moved fountain assembly from generate_scene.py into blender/osmassets/fountain.py, updated P2 refactor docs, and verified py_compile, 51 pure tests, and Blender/Cesium parity before/after with identical snapshots.

Session 5: Extract building module
Date: 2026-08-03
Task: Extract building module
Branch: main
Summary
Moved building assembly from generate_scene.py into blender/osmassets/building.py, updated P2 refactor docs so only roads remains in generate_scene.py, and verified py_compile, 51 pure tests, and Blender/Cesium parity before/after with identical snapshots.

Session 6: Extract road assembly module
Date: 2026-08-03
Task: Extract road assembly module
Branch: main
Summary
Moved Blender road GeoJSON assembly and OSM fallback roads into blender/osmassets/roads.py while preserving road_counts, Layer catalog warnings, scene metadata, and SCENE_DONE output. Verified py_compile, unittest, task validation, and Blender/Cesium parity before/after as identical for both sample areas.

Session 7: Add feature registry dispatch
Date: 2026-08-03
Task: Add feature registry dispatch
Branch: main
Summary
Introduced blender/osmassets/features.py with FeatureHandler and dispatch_ways for ordered OSM way feature dispatch. Converted generate_scene.py water/grass/scrub/tree_row/building branches into registry handlers while keeping material order, counts, road warning behavior, scene metadata, and SCENE_DONE unchanged. Verified py_compile, unittest, task validation, and Blender/Cesium parity before/after as identical for both sample areas.

Session 8: Clean stale tuft density comment
Date: 2026-08-03
Task: Clean stale tuft density comment
Branch: main
Summary
Cleared stale D3 tuft_density_wave comment debt and updated parity guide known-defect records without changing executable scene generation logic. Verified py_compile, 51 pure tests, and task validation.

Session 9: Improve Cesium cruise smoothness
Date: 2026-08-03
Task: Improve Cesium cruise smoothness
Branch: main
Summary
Reduced Cesium preview cruise stutter by lowering dense scrub bush nodes in nantaizi from 707 to 266, preserving scrub ground cover, and trimming preview route/follow hot-path overhead without lowering default visual clarity. Verified nantaizi blender/cesium/preview rebuild, node --check, py_compile, 51 pure tests, and task validation.

Session 10: Reject low-poly scrub bush experiment
Date: 2026-08-03
Task: Reject low-poly scrub bush experiment
Branch: main
Summary
Tested user-supplied assets/models/custom/bush_low/bush_low.glb for nantaizi scrub edge bushes. Geometry dropped from 63,762 verts / 67,536 indices to 4,044 / 4,050 and GLB size dropped from 31.96 MB to 27.51 MB with 266 scrub bush nodes unchanged, but user validation found the visual effect unsatisfactory. Restored generate_scene.py to the original default bush asset, archived the task, and recorded the rejected experiment in changelog/spec without adding bush_low to git.
