## Module

## Status

VERIFIED
|
|
|
|
## Description
|
|
The compare feature implements a three-pane layout with categories, items, and proof panes for side-by-side comparison workflows.
|
|
|
|
## Implementation Details
|
|
- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/compare/components/`
|
|
- **Components**:
|
|
- `three-pane-layout` (`src/Web/StellaOps.Web/src/app/features/compare/components/three-pane-layout.component.ts`)
|
|
- `categories-pane` (`src/Web/StellaOps.Web/src/app/features/compare/components/categories-pane.component.ts`)
|
|
- `items-pane` (`src/Web/StellaOps.Web/src/app/features/compare/components/items-pane.component.ts`)
|
|
- `proof-pane` (`src/Web/StellaOps.Web/src/app/features/compare/components/proof-pane.component.ts`)
|
|
- `compare-view` integration (`src/Web/StellaOps.Web/src/app/features/compare/components/compare-view.component.ts`)
|
|
- **Services**:
|
|
- `delta-compute` (`src/Web/StellaOps.Web/src/app/features/compare/services/delta-compute.service.ts`)
|
|
- **Behavior coverage**:
|
|
- `src/Web/StellaOps.Web/src/tests/compare/three-pane-layout.behavior.spec.ts`
|
|
- **Source**: Feature matrix scan (corrected during QA verification)
|
|
|
|
## E2E Test Plan
|
|
- **Setup**:
|
|
- [ ] Log in with a user that has appropriate permissions
|
|
- [ ] Navigate to compare workflow route
|
|
- [ ] Ensure compare session test data exists (baseline/current scan pair)
|
|
- **Core verification**:
|
|
- [ ] Verify the three panes render with deterministic panel ordering
|
|
- [ ] Verify category selection updates item filter and resets item selection
|
|
- [ ] Verify selected item/category propagate into proof/categories panes
|
|
- **Edge cases**:
|
|
- [ ] Verify graceful handling when no category is selected (filter clear)
|
|
- [ ] Verify responsive layout behavior at reduced viewport widths
|
|
- [ ] Verify keyboard/accessibility semantics for pane interactions
|
|
|
|
## Verification
|
|
- Run ID: `docs/qa/feature-checks/runs/web/three-pane-layout/run-001/`
|
|
- Date (UTC): 2026-02-11
|
|
- Tier 0: PASS (source/symbol verification for compare three-pane components and behavior spec).
|
|
- Tier 1: PASS (`npm run test` focused suite: 18 files / 92 tests; `npm run build` passed with known baseline warnings).
|
|
- Tier 2: PASS (behavioral verification of pane rendering, explain-mode/role propagation, deterministic filtering transitions, and cross-pane state propagation).
