CatanBot: Colonist HUD

About

CatanBot is a side-panel HUD for colonist.io that runs alongside your Catan game and surfaces decision-support information in real time, the way a chess engine's analysis bar sits next to a chess board.

WHAT IT DOES
• Opening picks · ranks every legal corner for both your 1st and 2nd settlement using complement-aware production scoring, port adjacency, denial value, and resource diversity. Pairs each pick with a follow-up road suggestion.
• In-game recommendations · top-N action ranking with score breakdowns. Settlement, city, road, dev card, port trade, player-trade proposal. Each rec carries a 1-ply lookahead delta showing how much better the bot's pick is than the alternative.
• Dev-card play hints · Knight, Monopoly, Year of Plenty, Road Building each get a typed PLAY/HOLD verdict with plain-language reasoning ("an opp is close to Largest Army · play to deny", "robber's on you · play to clear it").
• Robber & 7-roll telemetry · top robber targets ranked by blocking value × victim VP × hand size × resource scarcity. Auto-detects colonist's optional Friendly Robber rule.
• Strategy archetype tracker · once your opening settlements land, the bot detects which archetype you're playing (Ore-Wheat-Sheep, Longest Road rush, Port trader, Road Builder, or Balanced) and biases its recommendations accordingly. Mid-game pivot triggers (hot numbers, dev cards drawn, opponents closing on Largest Army) keep the strategy responsive.
• Live HUD · roll histogram with 36-roll baseline, eval sparkline (chess-style position graph), per-build move-quality grading, opponent hand inference, production rate.
• Variant board support · runs on the weekly-rotation variants too: the Pond and Twirl layouts, the Gold Rush fog board, and the Volcano gold-and-fog map, not just the standard board.
• Auto-postmortem · when a game ends, a self-contained HTML report opens automatically: winner, final VP breakdown, dice fairness, hand dynamics, trade quality, 7-roll impact, and the full game-progression charts.
