  "title": "Give each language its own evidence trail",
  "summary": "Two languages can share a calendar without sharing one score.",
  "kind": "protocol",
  "body": "Track real performance separately for each language: current target situations, recurring errors, active phrase set, delayed retrieval and spontaneous samples. Cross-language influence can help or interfere depending on the feature and learner, so diagnose actual transfer instead of assuming that parallel study is either always efficient or always harmful.",
  "limits": [
    "Research on cross-linguistic influence does not justify a universal rule to separate or combine languages by day. Scheduling should follow goals, available time and observed interference."

      "claim": "Cross-linguistic influence in multilingual learning can be facilitative or inhibitory, with direction and strength affected by factors such as proficiency, language status, linguistic proximity, recency and dominance.",

      "role": "supports",
      "note": "This does not establish that simultaneous English and German study is inherently beneficial or harmful for a particular adult learner.",

  "use_when": [
    "You are learning two or more languages and overall study time is visible, but progress and interference are hard to diagnose."
  ],
  "avoid_when": [
    "Research on cross-linguistic influence does not justify a universal rule to separate or combine languages by day. Scheduling should follow goals, available time and observed interference."
  ],
  "example": "English may be maintained through work meetings while German gets a deliberate speaking cycle; their errors and retrieval queues remain separate even if the same learning system stores both.",
  "check": "A learner can say what is improving in each language without using total study minutes as the main evidence.",
