stance
How the offer faces the store that recorded it — addressed (the party stated the deal to this store: a supplier's quote the store can buy at, or the store's own offer stated to its customers) or observed (witnessed, never actionable: a rival's shelf price recorded for comparison). A per-statement qualifier riding the offered-by statement, and a mandatory one: every offered-by statement must carry its stance, because stance is the cost-defining switch and a mute record can neither enter nor be excluded from the money reads. Never a fact about the party globally — the same party can supply a store wholesale AND retail against it across town, taking a different stance in each offer. Stance defines the cost read: cost = addressed offers read from the store's own chair; an observed price sits on the record without ever corrupting a margin report.
Stance is answered with one word chosen from the stances list — the same word shared across every product that uses it.
It is a qualifier of offered by — it has meaning only inside a offered by statement, one per statement, never on its own. It belongs with offered by to pricing — what it costs.
It is answered inside every offered by statement, not as a standalone question on a kind.
Answered inside every offered by statement — not a standalone slot on any kind.
