1503-1519 Mona Lisa Long-Duration Completion Node
This node extends the 1503 portrait anchor into the full long-duration working window used on site pages. It separates identity confidence from evolving object-state and completion-phase interpretation.

Identity vs completion

Anchor Snapshot
Mona Lisa interpretation on the site now has two required anchors: a dated identity baseline and a long-run completion window. This node defines the second anchor so routes can discuss evolving execution without weakening identity clarity.
Evidence Matrix
| Anchor | Evidence Class | Interpretive Role |
|---|---|---|
| 1503 portrait note layer | Dated documentary evidence | Maintains identity confidence while later state-claims are evaluated separately. |
| ~1503-1519 duration language | Chronology and process evidence | Supports phased completion narratives without implying a single-session production model. |
| Louvre-Prado comparative branch | Version-family and technical comparison evidence | Routes cross-object analysis into version trees and attribution controls. |
System Impact: Timeline and Cast
Bridges the 1503 identity anchor and late-career continuity windows.
System Impact: Attribution Track
Adds a standard route for identity-certain but completion-variable interpretation.
Open Questions for Next Pass
- Should long-duration works always display separate start-date and completion-window fields?
- How should Louvre-Prado branch evidence be summarized for non-specialist readers?
- Which completion-claim thresholds should trigger mandatory attribution disclaimers in work-page headers?
