A plan code does NOT map to a CANOPY tier on\nits own — the mapping depends on the customer's **market (region)** and\n**status**, so you must look it up in the crosswalk, never guess from the letter.\n- **Standard** plans (AS2, AS4) → Pine, everywhere.\n- **Preferred AP3** means different things by market: in the Northeast it is the\n  Evergreen tier, but in the Southeast AP3 was a relabeled Standard → Pine.\n- **AP3 and AP1 are closed to new business.** A prospect cannot be put on them;\n  the live preferred plan for new business is **AP5** (→ Evergreen). **AP1** is\n  grandfathered for existing customers only and maps to the **retired Heritage**\n  tier, which cannot be re-bound once dropped.\nWhen an EVERGREEN record and the CANOPY policy disagree, treat it as an\nunverified migration discrepancy: surface it, do not silently \"correct\" either side.\n"
