TIDAL-01 Descriptive editorial chapter guide; not a speech transcript or complete action log. GUI states and native outcomes are edited; repetition, checks and waiting are condensed. External Codex-supervised controller using NorthCUA Desktop MCP tools. Tool-interface showcase, separate from native Harness Runtime demos and NorthCUA checkpoint benchmarks. The workflow moves from an Inkscape sketch to an editable Blender craft with fitted inlays and an animated iris. Material settings, camera motion and saved scene state are checked. The 12-second native result film appears at 85.750–97.750 seconds in this edit. It is an authored output, not the task runtime or a physics simulation. 00:00:00.000–00:00:03.250 Opening 00:00:03.250–00:00:21.500 01 / Draw the three-view concept 00:00:21.500–00:00:38.125 02 / Shape the hull and fitted inlays 00:00:38.125–00:00:56.000 03 / Build and key the iris mechanism 00:00:56.000–00:01:15.750 04 / Author the metal, motion and glass 00:01:15.750–00:01:25.750 05 / Light, key the camera and save 00:01:25.750–00:01:37.750 RESULT / Native Blender film 00:01:37.750–00:01:40.750 Closing
