+List every viable answer in an ordered list and mark your recommended answer.
+Word each question so "yes" accepts your recommended answer.
 
-After each answer, settle the answered decision.
-Add decisions that the answer reveals.
-Move every newly ready decision into the frontier.
-Keep decisions with unresolved prerequisites outside the frontier.
+Each user answer reshapes the tree: settled decisions push the frontier outward and unblock questions that depended on them. Recompute the frontier in the file and ask the next question. A question whose answer depends on another open question belongs later, not next.
 
 Finding _facts_ is your job, never the user's. When a frontier question needs a fact from the environment (filesystem, tools, etc.), find it with available tools; don't ask the user for anything you could look up yourself. The _decisions_ are the user's: put each to them and wait.
 
-Finish when the frontier is empty.
-Present every settled decision from the design tree.
-Wait for user confirmation before acting on the decisions.
+The session is done when the frontier is empty: every branch of the design tree visited, nothing left silently assumed. Present every settled decision from the design tree. Do not act on it until the user confirms you have reached a shared understanding.
