One row per rule, each showing its own input and what it did to the date. A step we could not verify says so instead of resolving itself.

| Continuity chain | Every parent in the chain resolved | no change | High confidence |
| Patent term adjustment | +533 days, USPTO patent term adjustment record | Mar 13, 2028 | High confidence |
| Terminal disclaimer cap | Disclaimer resolved from the filed document (refs US 7,841,224, US 8,250,900) | capped to Sep 27, 2026 | High confidence |
