F5 — External PK (STUB)

⚠️ MVP uses EcoLive's own custom template, NOT the real export format from Kalodata/EchoTik. Zero Kalodata/EchoTik samples exist in this repo (01_DATA_SAMPLES/ has no competitor files), so the columns in the template below are guessed from the description in product-spec.md, not confirmed with the real vendor. When a real Kalodata/EchoTik API/export exists (PHASE_3_automation.md §3.2), this is the part that will change — the numbers here are only to see the comparison UI/logic working, not for real decisions.
