- The Templates card replaces the entire board in one click, filling every open slot from a pre-tested list.
- Every template is proven to replay clean through the board’s own engine before it ships.
- If a template calls for a rejected piece, the fill stops at that exact piece and names it.
- Open Frontiers samples untried combinations and ranks them by uncertainty width and plausible upside against cost, not popularity.
- The Laws panel lists the engine’s enforced rules verbatim and starts collapsed.
- All three cards render on a brand-new, empty board, not only mid-build.
The real starting point on /build is three cards in the left rail: Templates, Open Frontiers, and Laws. Each does a different job, and every one of them is visible before a single piece gets placed.
The Templates card replaces the whole board in one click
Clicking one entry in the Templates card replaces the entire board in a single move, filling every open slot at once. Each template is a short, ordered list: which slot, which piece, in that order. The list does not guess.
Every template ships only after its full list of picks is proven to replay clean through the same engine the board runs on. That proof happens before publication, not at click time. The page’s older loose-button version, three separate buttons with no such proof step behind them, is gone; nothing links to it.
If a template calls for a piece the engine rejects, the fill stops at that exact piece and names it. The rest of the template does not apply, and no piece gets silently dropped.
Open Frontiers surfaces what has not been tried
A second card below Templates samples combinations of pieces not yet tried and ranks them by two factors: how wide the uncertainty is and how much upside is plausible, weighed against the cost to run that combination.
The score is the product of two estimated terms, the confidence width of the untried combination and its plausible lift, divided by the summed cost of the modules it would run.
It does not rank by popularity among other builders, and it does not enumerate every possible combination. It samples a set, ranks it, then returns a short list. That makes it a discovery tool, not a confirmation tool, and the page keeps the two cards separate for that reason. A builder chasing a fast start reaches for Templates; a builder testing an idea reaches for Open Frontiers.
The Laws panel lists the engine’s enforced rules
A third card, collapsed by default, holds the rules the lattice enforces on itself. The text comes straight from the engine that runs the board, not from a rewritten summary.
The panel starts closed so it does not crowd a first-time visit, but it stays available before anyone builds on top of the rules it lists. None of the three cards is gated behind a mid-build state: they render identically on a brand-new, empty board and on a board already in progress.
The Donk Check
The Templates card gives a proven starting board in one click. The Laws panel sits next to it, stating exactly what "proven" is allowed to mean here. Starting from a proven board replaces a from-scratch build assembled by feel with one the engine has already replayed.
What is not yet measured: whether visitors actually open the Laws panel or scroll past it. That is a click-tracking question, not a code question, and no number has been pulled for this piece yet. The board itself is at /build, open before deciding.
FAQ
Does clicking a template erase what I already built? Yes. A template replaces the whole board in one move. That is the point: one click, a complete, tested starting point.
What happens if a template tries to use a piece that is no longer available? The fill stops at that exact piece and reports it. It never finishes the rest of the template and never quietly skips the broken part.
Is Open Frontiers just a list of the most popular combinations? No. It samples combinations and ranks them by uncertainty and plausible upside against cost, not by how many other builders picked them.
Do I have to open the Laws panel to use the builder? No, it starts collapsed. It is there for anyone who wants to see the enforced rules before building.
Do these three cards only show up once I have started building something? No. All three render on a brand-new, empty board, not only mid-build.
