1483-1508 Virgin of the Rocks Version Divergence Node
This node tracks the long arc from the 1483 commission framework to the 1508 delivery endpoint. It is the core route for handling two-version logic without collapsing contractual, technical, and attribution evidence into a single claim layer.

Version divergence
Contract to delivery chain
Anchor Snapshot
The Virgin of the Rocks family is one of the strongest test cases for structured version handling. The site already carries the 1483 contract cluster; this node extends that route across the full version branch and delivery timeline, including Louvre and London evidence paths.
Evidence Matrix
| Anchor | Evidence Class | Interpretive Role |
|---|---|---|
| 1483 commission framework | Documentary and contractual evidence | Establishes baseline obligations and collaborator context for later branch analysis. |
| Louvre and London panel divergence | Object-level and technical comparison evidence | Supports version-tree interpretation without forcing single-state authorship narratives. |
| 1508 endpoint in delivery chain | Chronology and legal-process evidence | Anchors long-window sequencing from commission start to documented closure moment. |
System Impact: Timeline Context
Connects early Milan commission context to long-window completion and route continuity.
System Impact: Attribution Track
Defines confidence-language controls for contract-linked multi-hand production contexts.
Open Questions for Next Pass
- Which version-level claims should be mandatory in side-by-side comparison modules?
- How should conservation-era discoveries be tiered against contract-document anchors?
- Where should workshop-hand language be normalized across Virgin of the Rocks and other version families?
