State Update Rules

Atomicity

All state updates must be atomic - read current state, apply changes, write entire state.

Immutability

Never mutate state in place. Always create new state object with changes.

Validation

Before writing state, validate against schema to prevent corruption.

Timestamps

Always update updated_at on every state change.

function updateState(workDir, updates) {
  const currentState = JSON.parse(Read(`${workDir}/state.json`));

  const newState = {
    ...currentState,
    ...updates,
    updated_at: new Date().toISOString()
  };

  // Validate before write
  if (!validateState(newState)) {
    throw new Error('Invalid state update');
  }

  Write(`${workDir}/state.json`, JSON.stringify(newState, null, 2));
  return newState;
}
