-## Status Snapshot
-- Classification: `dead`
-- Confidence: `high`
-- Recommendation: `investigate`
-- Preservation value: `medium`
-- Feature branch: `Lineage`
-- Source: `features/lineage/components/node-diff-table/diff-table.component.ts`
-- Selector: `app-node-diff-table`
-
-## What Is It?
-Node Diff Table appears to be a dedicated feature surface in the Lineage / Components / Node Diff Table area.
-
-## Why It Likely Fell Out Of The Product
-No route or runtime references remain in the current Angular shell, which suggests the surface was dropped or replaced.
-
-## What Is Worth Preserving
-Preserve the underlying workflow only if current product docs still claim the capability or if the component contains unique UI concepts.
-
-## Likely Successor Or Merge Target
-Needs branch-level review against current IA
-
-## Static Evidence

-### Route files
-- none
-
-### Menu surfaces

-## Next-Pass Questions
-- Check whether newer routed pages already absorbed this workflow under a different name.
-- Review component templates and services for reusable UX or domain language worth salvaging.
-- Validate the preservation call against current Stella Ops product docs before archival.
