+# Verdict Ladder UI (8-step verdict explainability)
+
+## Module
+Cli (with Web frontend)
+
+## Status
+VERIFIED
+
+## Description
+8-step verdict ladder providing visual explainability for verdict computation stages. Both CLI verdict commands and Angular UI component are implemented.
+
+## Implementation Details
+- **Verdict CLI commands**: `src/Cli/StellaOps.Cli/Commands/VerdictCommandGroup.cs` -- `stella verdict verify`, `stella verdict list`, `stella verdict push`, `stella verdict rationale`
+- **Compare CLI**: `src/Cli/StellaOps.Cli/Commands/Compare/CompareCommandBuilder.cs` -- `stella compare` with base/target diff
+- **Explain CLI**: `src/Cli/StellaOps.Cli/Commands/ExplainCommandGroup.cs` -- `stella explain` for block/decision explanations
+- **Score Gate CLI**: `src/Cli/StellaOps.Cli/Commands/ScoreGateCommandGroup.cs` -- score gate with baseline comparison
+- **Verdict Ladder Angular component**: `src/Web/StellaOps.Web/src/app/features/triage/components/verdict-ladder/verdict-ladder.component.ts` -- full stepper visualization with `VerdictLadderStep` (step, name, status: complete/partial/missing/na, summary, evidence items), `EvidenceItem` (type, title, source, hash, signed, signedBy, uri, preview), `VerdictLadderData` model
+- **Verdict Ladder builder service**: `src/Web/StellaOps.Web/src/app/features/triage/services/verdict-ladder-builder.service.ts` -- builds ladder data from backend evidence
+- **Policy explainability library**: `src/Policy/__Libraries/StellaOps.Policy.Explainability/` -- policy decision explainability
+- **Policy engine**: `src/Policy/StellaOps.Policy.Engine/` -- verdict computation with deterministic evaluation
+
+## E2E Test Plan
+- [ ] Verify verdict ladder renders all 8 steps with correct pass/fail/skip status
+- [ ] Verify clicking a ladder step expands to show underlying evidence
+- [ ] Verify evidence items show hash, signature status, and source
+- [ ] Verify `stella verdict rationale` CLI output matches ladder steps
+- [ ] Verify ladder updates when verdict is recomputed
