|---|---|---|---|
| Member PII | 26–42 | pattern match — a shape, not a proof | cmb-member-pii |
One span here is seeded, not re-derived. 26–42 — 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.

- captured Jul 13, 2026 at 2:26 PMA. Bergström (Senior credit analyst, Credit Administration) — prompt to Claude.ai (personal).
- classified Jul 13, 2026 at 2:26 PM1 span in member_pii; proof recorded on each span.
- decided Jul 13, 2026 at 2:26 PMwarn under policy v3, from the member_pii cell for the credit role group.
- transformed Jul 13, 2026 at 2:26 PMSafe transform taken on the coach card: 1 span(s) masked in place by offset. Warn does not rewrite anything by itself — the person chose this. The tokenize option is not on for the account_numbers cell in the credit role group under v3, so every span is masked.
- submitted Jul 13, 2026 at 2:26 PMSubmitted to Claude.ai (personal) after transformation; the original text was not sent.
