Post-submission flow and recommendation routing

DEC-0003 - Post-submission flow and recommendation routing

Context

Need clear behavior after user submits an exercise.

Decision

• User always lands on Result page after submission.
• Result page shows outcome and explanation.
• On exit, user can go to Practice Management.
• Practice Management includes “recently completed exercise + next suggestions”.
• Suggestions are diversified and allow switching skills.
• Default recommendation order after submission:
  1. practice matched to just-finished result,
  2. practice in same topic,
  3. practice in different skill.
• Repeated exercise suggestion is blocked within 7 days.
• Default number of suggestions is 5.

Suggestion intent

• Weak result -> easier corresponding practice.
• Good result -> one equivalent and one harder suggestion.

Rationale

Keep users in a guided loop while preserving choice and multi-skill exploration.

Validation signal

Higher next-action continuation from result context to next practice.
