 ## Replay Foundation
 
-The Go API client exposes `GetGameHistory(gameID)` and
-`GetMyGames(limit, offset)`, including durable result, timestamps, player
-claims, move count, ordered UCI moves, and FEN after every move. Interactive
-`games`/`replay` commands and terminal playback controls are intentionally

+The Go API client exposes `GetGameHistory(gameID)`, `GetGamePGN(gameID, ply)`,
+and `GetMyGames(limit, cursor)`, including durable result, timestamps, player
+claims, move count, ordered UCI and SAN moves, and FEN after every move. The
+`games` and `pgn` commands use them; step-by-step `replay` controls are still
+planned, see [Replay Implementation Tasks](./todo.md).
