 2026-10-04, Lilleman auf Larv. Serves goal 3. The nine-seat panels in `todo.md`'s git history, 2026-09-22 to 2026-09-30, held the score between 5.2 and 6.1, with Locality lowest at every seat, and the hardest units were the draw fences that change deleted. The change making every `{…}` draw afresh, the move of the draw state into `internal/drawstate` and `todo.md` items 98 to 106 delete or move what the earlier chunks of the below-floor round touched, so a scoring run before item 106 merges would score code about to go; the calc change accepting a name as an operand shipped unscored on 2026-10-05 for that reason. With the change making every `{…}` draw afresh, the move of the draw state and items 98 to 106 are the restructure the maintainer approved, which `AGENTS.md`'s comprehension rule lets merge below the floor. No scoring run or panel runs until item 5, which runs the nine-seat panel and larv-review's scoring run. The scoring run writes this entry's first scores. Valid until `todo.md` item 5 runs.

 2026-10-05, Lilleman auf Larv. Serves goals 3.2 and 3.4. Two architect reviews found the
 engine's types, `template`, `table`, `arm`, `op` and `nameBinding`, bound in one cycle
 because several passes each write part of the same structs; the template language's
 recursion reads few of those types. Moving the engine before items 101 and 104 to 106 give
 each value one writer would spread that knot across packages, behind forwarding calls from
