The standard
Methodology and versions
Every model and document that decides a status, a score or a class is versioned, effective-dated and hashed. Nothing is changed in place.
| Version | Effective from | Effective to | Hash | Changes |
|---|---|---|---|---|
| score-model 1.2.0Live | 01 Sep 2026 | Current | 0x1a7d...0b9d | Evidence expiry now removes category points on the expiry date rather than at the next review; Custody weight unchanged at 10. |
| score-model 1.1.0 | 15 May 2026 | 31 Aug 2026 | 0x2b8e...1e0b | Lifecycle Reporting split from Financial Transparency; eight categories from seven. |
| score-model 1.0.0 | 20 Jan 2026 | 14 May 2026 | 0x3c9f...2f1c | First published model; seven categories summing to 100. |
Re-scoring on a new version
A new scoring or risk model applies to new cases from its effective date and to existing listings at their next scheduled review. Passports show both the version that scored them and the version currently in force, so a difference is visible, never silent.
