room.go was 1919 lines with every room concern in one file. Pure moves, no signature or behaviour changes: room.go keeps the struct, its constructor, the input loop and the small seat-authority helpers; room_inputs.go the message types; room_lobby.go seating and the lobby between games; room_game.go everything that touches a running game; room_presence.go the reconnect window and resume; room_chat.go the room's own conversation; bot_board.go the bot's frozen view of a position. session.go was two unrelated halves in one 762-line file: the socket (session.go, kept) and the protocol (dispatch.go, new) — dispatch and the handshake/resume flow it routes into. Verified with go build, go vet, golangci-lint and go test -race, and by counting: every one of the 89 room.go and 27 session.go top-level declarations appears in the split exactly once.
