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.

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 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.

Session 27: QGIS traffic signal editing and countdown stability

Date: 2026-08-07 Task: QGIS traffic signal editing and countdown stability Branch: main

Summary

Implemented editable traffic signal assemblies in QGIS with stable IDs, position/heading overrides, reimport ownership, source validation, and Blender/Cesium runtime derivation. Fixed long signal IDs overflowing Blender node names with short nodeKey values, and changed QGIS SVG symbols to direct heading_deg field rotation so QGIS rotation edits write back to the field. Verified real GeoPackage round-trip, focused Node tests, preview tests, and 59 Blender tests. Safari cache caused stale GLB symptoms and was resolved with a hard refresh.
