• ✓Idea: the Tower of London, the planning task clinics actually use
• ✓Three posts holding 3, 2 and 1 — the short one is what forces a plan
• ✓The technique is taught first: work backwards from the goal
• ✓Every printed minimum is the true breadth-first distance — npm run verify:route
• ✓Take one back, start over, or ask for exactly one move — always available
• ✓EQ: three resets buys a breath with Captain Mek before looking again
• ✓A painted harbour behind the posts, instead of drawn onesplanned
• ✓A four-lantern ladder for anyone who finishes the tenplanned

✓ = done · ☐ = planned. Every game is built one step at a time like this.
