ChessLM web training workspace capture

Story

ChessLM carries one training product across a web workspace and Unity board.

Problem

A chess training product has to keep reasoning, board state, and client targets aligned.

Constraint

The public case uses owned captures and keeps provider secrets server-side.

Approach

Use the web workspace for training. Use the Unity board as the client. Keep the product boundary clear across browser, iPhone, and iPad targets.

Outcome

The case shows the same training product across browser and game-client contexts.

Human stake

A player should be able to follow the lesson without wondering which surface owns the state.

Blocked person

A player trying to connect coaching, board state, and the next move.

Confusion

Training gets noisy when reasoning, board state, and client target feel like separate products.

Made visible

The reel connects web workspace and Unity board.

Evidence

Web workspace and Unity board captures show the same product across browser and game-client contexts.

Problem

Training state has to stay aligned.

The browser workspace shows the reasoning, and the board client has to carry the same state.

Operate

The product crosses clients.

The training reel moves from workspace context into the Unity board without exposing provider secrets.

The board becomes the client.

The Unity board capture shows the training client across browser, iPhone, and iPad direction.
