Pathway Reviewer - Final Validation

Verdict

Approved. All requested success criteria are met.

No blocking issues found.

Hover parity across graph and cards: Pass
- Card hover drives graph highlight via onNodeHighlight -> highlightedNodeId -> CareerConstellation highlight effect.
- Graph hover drives card highlight via onNodeHover -> highlightedRoleId consumed by timeline cards.
Hover jitter/reflow artifacts: Pass
- D3 initialization effect in CareerConstellation depends on dimensions only.
- Highlight updates are decoupled via refs/effect (highlightGraphRef) and no longer recreate simulation.
Timeline/card date consistency from one canonical source: Pass
- Canonical entities are defined in src/data/timeline.ts.
- consultations and constellation role/edge data are compatibility layers derived from canonical timeline entities.
Unified career/education card flow and pills: Pass
- TimelineInterventionsSubsection renders one ordered list from timelineEntities.
- Career entries show Career Intervention pill.
- Education entries show Education Intervention pill and right-aligned layout class.
Standalone duplicate education section removed: Pass
- DashboardLayout uses unified timeline subsection; separate education subsection path is removed.
Sidebar tags from canonical skill aggregation: Pass
- src/data/tags.ts derives tags from getTopTimelineSkills() (most frequent first).
Quality gates: Pass
- npm run lint: pass (2 existing warnings, 0 errors)
- npm run typecheck: pass
- npm run build: pass

Validation for "no jitter" is based on lifecycle/code-path inspection plus successful build gates.
Existing non-blocking warnings remain in context providers (react-refresh/only-export-components).
