      • QA notes:
        • Completion now requires pre/post evidence (two temperature log CSV artifacts) and an explicit flow-stability verification decision.
        • Failed verification routes into a recovery branch (mesh inspection + O-ring reseat) before re-running the flush path.

      • Quest link: /quests/geothermal/replace-faulty-thermistor
      • Unlock prerequisite:
        • requiresQuests: geothermal/install-backup-thermistor
      • Dialogue requiresItems gates:
        • stage → "Spare probe and logger are ready" - Arduino Uno ×1
        • replace → "Capture post-replacement baseline" - Arduino Uno ×1
        • replace → "Baseline capture saved" - Arduino Uno ×1
        • verify → "Parity holds across the verification window" - Arduino Uno ×1
        • troubleshoot → "Corrective action done, re-run baseline" - Arduino Uno ×1
        • finish → "Replacement thermistor verified" - Arduino Uno ×1
      • Grants:
        • Dialogue options/steps grantsItems: None
        • Quest-level grantsItems: None
      • Rewards:
        • Solarpunk Award ×1
      • Processes used:
        • arduino-thermistor-read
          • Requires: Arduino Uno ×1, solderless breadboard ×1, Jumper Wires ×3, USB Cable ×1, Thermistor (10k NTC) ×1, 10k Ohm Resistor ×1
          • Consumes: none
          • Creates: none
      • QA notes:
        • Completion now requires post-replacement baseline capture and a 10-minute parity verification window against backup probe data.
        • Drift/dropouts branch into reseat/moisture troubleshooting with a required recapture loop before finish.

      QA flow notes

      • Cross-quest dependencies: follow quest unlocks in order; each quest above lists exact requiresQuests and inventory gates that must be present before completion paths appear.
      • Progression integrity checks: verify each process-backed step can be completed either by running the process or by satisfying the documented continuation gate items.
      • Known pitfalls: repeated processes may generate stackable logs or outputs; validate minimum item counts on continuation options before skipping process steps.
