- People documenting or building plank structures
- Worth noticing
- The validator checks each plank in placement order and can test whether the structure stands after every step.
Field notes
The sample file places planks in build order, with Markdown prose between fenced blocks; coordinates use plank-thickness units, and repeat/offset fields compact the wall layers. The default dimensions are 15 × 3 × 1 units, with a stated 7.8 mm unit size, while frontmatter can declare other plank ratios. The page lists a Node/browser validator and a player with live editing, diagnostics, replay, balance checks, and drop tests; the specification is labeled v0.1 draft.
