Two-phase plan: Casual bot first (algorithmic, ~200 LoC), then Recon bot
(gemma4:26b chat agent) with persistent private chat history per game.
Bots play through the same view filter and FSM as humans — no oracle access.
Endpoint priority: steel141 RTX 3090 Ti primary, pve197 V100 fallback. Mid-game
GPU failover allowed (one-way). Reasoning hidden from user during play, revealed
in collapsible post-game panel.
Reverses the 2026-04-28 DECISIONS.md row "Client-side AI / hint generation —
explicitly out of scope." Reversal is partial: human-vs-human hint generation
remains rejected; this spec only adds AI in the human-vs-AI path.
