qualifier token a chosen word

price eligibility

Which buyer segment a conditional sale price is gated to — any member, a business buyer, an end user, a loyalty tier, a first-order buyer. A qualifier of the sale-price host that collapses member-price / business-price / prime-exclusive / loyalty-price into one structure (the segment is the value). A filterable token from a growing vocabulary. The realised gate check (is THIS buyer a member) is downstream; the grammar that a sale price CAN be segment-gated is the pool's.

Price eligibility is answered with one word chosen from the price eligibility segments list — the same word shared across every product that uses it.

It is a qualifier of tier price — it has meaning only inside a tier price statement, one per statement, never on its own. It belongs with tier price to pricing — what it costs.

It is answered inside every tier price statement, not as a standalone question on a kind.
