Phase 4: Evaluation & Dashboard - Context

Gathered: 2026-02-20 Status: Ready for planning

## Phase Boundary

Quantitative comparison of all search approaches (3 embedding models + LLM baseline) with interactive exploration UI. Delivers metrics calculation, batch benchmarking over test set, and HTML dashboard for exploration and comparison. LLM-as-judge evaluation and static reports are separate (Phase 5).

## Implementation Decisions

Claude's Discretion

User delegated all implementation decisions. Claude has full flexibility on:

Comparison view:

Side-by-side layout design for 4 approaches
How to highlight differences between results
Result card design and information density

Metrics display:

Tables vs charts vs combination
Grouping and emphasis of accuracy, latency, cost
Aggregate statistics presentation

Batch benchmark UX:

Progress indication during benchmark runs
Results presentation format
Any export functionality

Dashboard interaction:

Query input flow and form design
Filtering and navigation patterns
View organization (single page vs tabs vs routes)

## Specific Ideas

No specific requirements — open to standard approaches.

User indicated the UI/UX details are not important to them. Focus should be on functional correctness of metrics and clear presentation of comparison data.

## Deferred Ideas

None — discussion stayed within phase scope.
