Invite: Which instruction keeps earlier contributions?
Encounter/model: Pretend snowflake badge: start0, add4 then2 gives6. Setting4 then2 gives2. Two designs may both be valid for different stories.
Own practical action: Generate two tiny designs for a chosen purpose; compare or dictate block order, select against a criterion, create/change the preferred programme and run. One meaningful alternative is enough before continuation.
Observe/check: Does the explanation tie the instruction difference to the user’s purpose and actual variable state?
Possible misconception: Saying “the longer programme is better” without checking the intended job.
Next teaching move: Offer a changed start/input that separates their two designs.
Use: choose one route, one model or neither where unnecessary. No30-route log or all-context quota. Home/extra 2 is an independent free offer, not required catch-up.
