|---|---|---|---|
| Member PII | 26–37 | pattern match — a shape, not a proof | cmb-member-pii |
One span here is seeded, not re-derived. 26–37 — the name is proven at that offset by the engine’s own name rule, and the identifier pairing that makes it Member PII is seeded rather than re-derived: this excerpt carries no identifier for the combination rule to pair with. The span is counted in every figure on this console; what it is not is a chain an examiner can replay end to end, which is why the evidence package prints only chains that reproduce exactly.
