+
+## Evidence-Weighted Score (EWS) Components
+
+The EWS component suite provides visual representations of vulnerability scores based on evidence-weighted analysis.
+
+### Core Components
+
+| Component | Purpose | Location |
+|-----------|---------|----------|
+| [ScorePill](./score-pill.md) | Compact score display with bucket coloring | `shared/components/score/` |
+| [ScoreBreakdownPopover](./score-breakdown-popover.md) | Detailed score breakdown with dimensions | `shared/components/score/` |
+| [ScoreBadge](./score-badge.md) | Evidence flag badges (live-signal, proven-path, etc.) | `shared/components/score/` |
+| [ScoreHistoryChart](./score-history-chart.md) | Timeline visualization of score changes | `shared/components/score/` |
+
+### Feature Components
+
+| Component | Purpose | Location |
+|-----------|---------|----------|
+| [FindingsList](./findings-list.md) | Findings table with EWS integration | `features/findings/` |
+| [BulkTriageView](./bulk-triage-view.md) | Bulk triage interface with bucket summaries | `features/findings/` |
+
+## Score Buckets
+
+All EWS components use a consistent bucket system:
+
+| Bucket | Score Range | Color | Priority |
+|--------|-------------|-------|----------|
+| Act Now | 90-100 | Red (`#DC2626`) | Critical - Immediate action required |
+| Schedule Next | 70-89 | Amber (`#D97706`) | High - Schedule for next sprint |
+| Investigate | 40-69 | Blue (`#2563EB`) | Medium - Investigate when possible |
+| Watchlist | 0-39 | Gray (`#6B7280`) | Low - Monitor for changes |
+
+## Evidence Flags
+
+Findings can have special flags indicating evidence quality:
+
+| Flag | Icon | Color | Description |
+|------|------|-------|-------------|
+| `live-signal` | Signal wave | Green | Active runtime signals detected |
+| `proven-path` | Checkmark | Blue | Verified reachability path confirmed |
+| `vendor-na` | Strikethrough | Gray | Vendor marked as not affected |
+| `speculative` | Question mark | Orange | Evidence is speculative/unconfirmed |
+

+# BulkTriageViewComponent
+
+Streamlined interface for triaging multiple findings at once with bucket-based organization.
+
+## Overview
+
+The `BulkTriageViewComponent` provides a triage-focused view with bucket summary cards, one-click bucket selection, and bulk actions.
+
+## Selector
+
+```html
+<app-bulk-triage-view />
+```
+
+## Inputs
+
+| Input | Type | Default | Description |
+|-------|------|---------|-------------|
+| `findings` | `ScoredFinding[]` | `[]` | Array of scored findings |
+| `selectedIds` | `Set<string>` | `new Set()` | Currently selected finding IDs |
+| `processing` | `boolean` | `false` | Whether an action is in progress |
+
+## Outputs
+
+| Output | Type | Description |
+|--------|------|-------------|
+| `selectionChange` | `EventEmitter<string[]>` | Emits when selection changes |
+| `actionRequest` | `EventEmitter<BulkActionRequest>` | Emits when an action is triggered |
+| `actionComplete` | `EventEmitter<BulkActionResult>` | Emits when an action completes |
+
+## Action Types
+
+```typescript
+type BulkActionType = 'acknowledge' | 'suppress' | 'assign' | 'escalate';
+
+interface BulkActionRequest {
+  action: BulkActionType;
+  findingIds: string[];
+  assignee?: string;      // For 'assign' action
+  reason?: string;        // For 'suppress' action
+}
+
+interface BulkActionResult {
+  action: BulkActionType;
+  findingIds: string[];
+  success: boolean;
+  error?: string;
+}
+```
+
+## UI Sections
+
+### Bucket Summary Cards
+Four cards showing findings grouped by priority bucket:
+- **Act Now** (red): 90-100 score
+- **Schedule Next** (amber): 70-89 score
+- **Investigate** (blue): 40-69 score
+- **Watchlist** (gray): 0-39 score
+
+Each card displays:
+- Bucket name and color
+- Finding count
+- "Select All" button
+- Selection indicator
+
+### Action Bar
+Appears when findings are selected:
+- Selection count
+- Clear selection button
+- Action buttons: Acknowledge, Suppress, Assign, Escalate
+- Undo button (when history exists)
+
+### Progress Overlay
+Shown during bulk operations:
+- Action name
+- Progress bar
+- Percentage complete
+- Items processed count
+
+### Modals
+- **Assign Modal**: Email input for assignee
+- **Suppress Modal**: Text area for suppression reason
+
+## Usage Examples
+
+### Basic Usage
+
+```html
+<app-bulk-triage-view
+  [findings]="scoredFindings"
+  [selectedIds]="selectedIds"
+  (selectionChange)="onSelectionChange($event)"
+  (actionRequest)="onActionRequest($event)"
+/>
+```
+
+### Full Implementation
+
+```typescript
+@Component({
+  selector: 'app-triage-page',
+  template: `
+    <app-bulk-triage-view
+      [findings]="findings()"
+      [selectedIds]="selectedIds()"
+      [processing]="processing()"
+      (selectionChange)="updateSelection($event)"
+      (actionRequest)="handleAction($event)"
+      (actionComplete)="onActionComplete($event)"
+    />
+  `
+})
+export class TriagePageComponent {
+  findings = signal<ScoredFinding[]>([]);
+  selectedIds = signal<Set<string>>(new Set());
+  processing = signal(false);
+
+  private triageService = inject(TriageService);
+
+  updateSelection(ids: string[]): void {
+    this.selectedIds.set(new Set(ids));
+  }
+
+  async handleAction(request: BulkActionRequest): Promise<void> {
+    this.processing.set(true);
+
+    try {
+      switch (request.action) {
+        case 'acknowledge':
+          await this.triageService.acknowledge(request.findingIds);
+          break;
+        case 'suppress':
+          await this.triageService.suppress(request.findingIds, request.reason!);
+          break;
+        case 'assign':
+          await this.triageService.assign(request.findingIds, request.assignee!);
+          break;
+        case 'escalate':
+          await this.triageService.escalate(request.findingIds);
+          break;
+      }
+
+      this.selectedIds.set(new Set());
+      await this.refreshFindings();
+    } finally {
+      this.processing.set(false);
+    }
+  }
+}
+```
+
+### With Toast Notifications
+
+```html
+<app-bulk-triage-view
+  [findings]="findings"
+  [selectedIds]="selectedIds"
+  (actionComplete)="showToast($event)"
+/>
+```
+
+```typescript
+showToast(result: BulkActionResult): void {
+  if (result.success) {
+    this.toast.success(
+      `${result.action} completed for ${result.findingIds.length} findings`
+    );
+  } else {
+    this.toast.error(`Action failed: ${result.error}`);
+  }
+}
+```
+
+## Bucket Selection
+
+### Select All in Bucket
+Click "Select All" on a bucket card to select all findings in that bucket.
+
+### Toggle Bucket
+Clicking "Select All" when all bucket items are selected will deselect them.
+
+### Partial Selection
+When some items in a bucket are selected, the button shows a partial indicator.
+
+## Action Descriptions
+
+| Action | Icon | Description |
+|--------|------|-------------|
+| Acknowledge | Checkmark | Mark findings as reviewed |
+| Suppress | Eye-off | Suppress with reason (opens modal) |
+| Assign | User | Assign to team member (opens modal) |
+| Escalate | Alert | Mark for urgent attention |
+
+## Undo Capability
+
+The component maintains an undo stack for recent actions:
+- Up to 5 operations stored
+- Undo restores previous selection
+- Toast shows "Undo" button after action
+
+## Accessibility
+
+- Bucket summary has `aria-label="Findings by priority"`
+- Select All buttons have `aria-pressed` state
+- Action bar has `role="toolbar"`
+- Progress overlay announces to screen readers
+- Modals trap focus and support Escape to close
+- Action buttons have descriptive labels
+
+## Keyboard Navigation
+
+| Key | Action |
+|-----|--------|
+| Tab | Navigate between elements |
+| Enter/Space | Activate buttons |
+| Escape | Close modals |
+
+## Styling
+
+```css
+app-bulk-triage-view {
+  --bucket-card-padding: 16px;
+  --bucket-card-radius: 8px;
+  --action-bar-bg: #f9fafb;
+  --modal-max-width: 400px;
+}
+
+/* Bucket colors */
+.bucket-card.act-now { --bucket-color: #DC2626; }
+.bucket-card.schedule-next { --bucket-color: #D97706; }
+.bucket-card.investigate { --bucket-color: #2563EB; }
+.bucket-card.watchlist { --bucket-color: #6B7280; }
+```
+
+## Responsive Behavior
+
+| Breakpoint | Layout |
+|------------|--------|
+| > 640px | 4 bucket cards in row |
+| <= 640px | 2x2 grid, action labels hidden |

+```
+
+## Accessibility Notes
+
+- All color combinations meet WCAG 2.1 AA contrast requirements (4.5:1 for text)
+- Bucket colors use both color and position/labels for identification
+- Flag badges use icons in addition to colors
+- Focus states use high-contrast ring colors

+- Fuzzing results
+
+### vendor-na (Gray - Vendor Override)
+The software vendor has issued a VEX statement indicating this vulnerability does not affect their product configuration or version.
+
+**Sources:**
+- Vendor VEX documents
+- CSAF advisories
+- Distro security teams
+
+### speculative (Orange - Unconfirmed)
+The evidence for this vulnerability is speculative or based on incomplete analysis. Score caps are typically applied.
+
+**Sources:**
+- Incomplete static analysis
+- Heuristic-based detection
+- Unverified reports
+
+## Accessibility
+
+- Uses `role="img"` with descriptive `aria-label`
+- Tooltip shown on focus for keyboard users

+# Compare Workflow User Guide
+
+**Version:** 1.0
+**Last Updated:** 2025-12-22
+
+## Overview
+
+The Compare workflow in StellaOps enables you to analyze what changed between two container image versions from a security perspective. Instead of reviewing entire vulnerability lists, you focus on **material risk changes** — the delta that matters for security decisions.
+
+## When to Use Compare
+
+Use the Compare view when you need to:
+
+- **Evaluate a new release** before deploying to production
+- **Understand risk delta** between current and previous versions
+- **Investigate policy gate failures** to see what caused blocking
+- **Review security posture changes** after dependency updates
+- **Audit compliance** by verifying what changed and why
+
+## Accessing the Compare View
+
+### From Release Details
+
+1. Navigate to **Releases** → Select a release
+2. Click the **Compare** button in the release header
+3. The system automatically selects the recommended baseline
+
+### From Build/Artifact
+
+1. Navigate to **Scans** → Select a scan
+2. Click **Compare with baseline**
+3. Select a baseline from the recommended options
+
+### Direct URL
+
+```
+/compare/{currentDigest}/{baselineDigest}
+```
+
+## Understanding the Interface
+
+### Baseline Selector
+
+At the top of the Compare view, you'll see the baseline selector:
+
+```
+Comparing: [myapp:v2.1.0] → [Select baseline ▼]
+                                  ├── Last Green Build (Recommended)
+                                  ├── Previous Release (v2.0.0)
+                                  ├── Main Branch
+                                  └── Custom...
+```
+
+**Baseline Options:**
+- **Last Green Build**: Most recent version that passed all security gates
+- **Previous Release**: The version tagged before the current one
+- **Main Branch**: Latest scan from the main/master branch
+- **Custom**: Manually select any previous scan
+
+### Baseline Rationale
+
+Below the selector, you'll see why this baseline was chosen:
+
+> "Selected last prod release with Allowed verdict under policy P-2024-001."
+
+This helps auditors understand the comparison context.
+
+### Delta Summary Strip
+
+The summary strip shows high-level counts:
+
+```
+┌────────────┬─────────────┬──────────────┬──────────────┬─────────────┐
+│ +5 added   │ -3 removed  │ ~2 changed   │ Policy: v1.2 │ Feed: 2h ago│
+└────────────┴─────────────┴──────────────┴──────────────┴─────────────┘
+```
+
+### Three-Pane Layout
+
+#### Left Pane: Categories
+
+Categories organize changes by type:
+
+| Category | Description |
+|----------|-------------|
+| **SBOM Changes** | Component additions, removals, version changes |
+| **Reachability** | Functions becoming reachable/unreachable |
+| **VEX Status** | Vulnerability status changes |
+| **Policy** | Policy rule trigger changes |
+| **Findings** | New or resolved vulnerabilities |
+| **Unknowns** | New gaps in analysis |
+
+Click a category to filter the items pane.
+
+#### Middle Pane: Items
+
+Shows individual changes sorted by risk priority:
+
+```
+┌─────────────────────────────────────────────────────────────┐
+│ ⊕ CVE-2024-1234 · lodash@4.17.20 · +reachable    [HIGH]    │
+│ ⊕ CVE-2024-5678 · requests@2.28.0 · +KEV         [CRITICAL]│
+│ ⊖ CVE-2024-9999 · urllib3@1.26.0 · -reachable    [MEDIUM]  │
+└─────────────────────────────────────────────────────────────┘
+```
+
+**Change Types:**
+- ⊕ Added (green): New in current version
+- ⊖ Removed (red): Gone from current version
+- ↔ Changed (yellow): Status or value changed
+
+#### Right Pane: Proof/Evidence
+
+When you select an item, the proof pane shows:
+
+1. **Witness Path**: Call path from entrypoint to vulnerable function
+2. **VEX Merge**: How multiple VEX sources were combined
+3. **Policy Rule**: Which rule triggered and why
+4. **Envelope Hashes**: Cryptographic evidence for verification
+
+### Trust Indicators
+
+The trust indicators bar shows:
+
+| Indicator | Description |
+|-----------|-------------|
+| **Det. Hash** | Determinism hash for reproducibility |
+| **Policy** | Policy version used for evaluation |
+| **Feed** | Vulnerability feed snapshot timestamp |
+| **Signature** | DSSE signature verification status |
+
+**Warning States:**
+- ⚠️ **Stale Feed**: Vulnerability data > 24h old
+- ⚠️ **Policy Drift**: Policy changed between scans
+- 🔴 **Signature Invalid**: Verification failed
+
+### Actionables Panel
+
+The "What to do next" section provides prioritized recommendations:
+
+```
+┌─────────────────────────────────────────────────────────────────┐
+│ What to do next:                                                │
+│ 1. [CRITICAL] Upgrade lodash → 4.17.21          [Apply]         │
+│ 2. [HIGH] Add VEX statement for urllib3         [Apply]         │
+│ 3. [MEDIUM] Investigate new reachable path      [Investigate]   │
+│ 4. [LOW] Resolve unknown: missing SBOM          [Investigate]   │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+## Common Workflows
+
+### 1. Pre-Release Security Review
+
+**Goal**: Verify a release is safe to deploy
+
+1. Open the release in the UI
+2. Click **Compare** (defaults to last green baseline)
+3. Review the delta summary:
+   - New critical/high vulnerabilities?
+   - Reachability increases?
+   - Policy violations?
+4. Examine each critical item:
+   - Check witness paths
+   - Review VEX status
+5. Apply actionables or approve release
+
+### 2. Investigating a Blocked Release
+
+**Goal**: Understand why a release was blocked
+
+1. Open the blocked release
+2. Look at the **Verdict** chip: `BLOCKED`
+3. Click **Compare** to see what changed
+4. Filter to **Policy** category
+5. Select blocking rules to see:
+   - Which policy rule fired
+   - Evidence that triggered it
+   - Remediation options
+
+### 3. Dependency Update Impact
+
+**Goal**: Assess security impact of dependency updates
+
+1. Compare current branch to main
+2. Filter to **SBOM Changes**
+3. Review component version changes:
+   - Check if upgrades fix vulnerabilities
+   - Check if new vulnerabilities introduced
+4. Filter to **Findings** for net impact
+
+### 4. Auditor Verification
+
+**Goal**: Verify security claims are accurate
+
+1. Open the Compare view
+2. Check **Trust Indicators**:
+   - Signature valid?
+   - Feed current?
+   - Policy version expected?
+3. Click **Copy Replay Command**
+4. Run replay locally to verify determinism
+5. Download **Evidence Pack** for records
+
+## Understanding Evidence
+
+### Witness Paths
+
+Witness paths show how vulnerable code is reachable:
+
+```
+main() [entrypoint]
+  ↓
+parseConfig()
+  ↓
+loadJson()
+  ↓
+yaml.load() [sink - CVE-2024-1234]
+
+Confidence: CONFIRMED
+Gates: input_validation, sandboxing
+```
+
+**Confidence Tiers:**
+- **CONFIRMED**: Call path verified through multiple sources
+- **LIKELY**: High-confidence static analysis
+- **PRESENT**: Function exists but reachability uncertain
+
+### VEX Merge Explanation
+
+When multiple VEX sources exist, the merge shows how they combined:
+
+```
+┌─────────────────────────────────────────────────────────┐
+│ VEX Status: NOT_AFFECTED                                │
+│ Strategy: priority                                      │
+│                                                         │
+│ Sources:                                                │
+│ ★ [vendor] RedHat RHSA-2024:1234 - not_affected    P1  │
+│   [distro] Ubuntu USN-5678-1 - affected            P2  │
+│   [internal] Team assessment - not_affected        P3  │
+│                                                         │
+│ Resolution: Vendor claim takes priority                 │
+└─────────────────────────────────────────────────────────┘
+```
+
+### Determinism Verification
+
+To verify a comparison is reproducible:
+
+1. Copy the replay command from Trust Indicators
+2. Run locally:
+   ```bash
+   stellaops smart-diff replay \
+     --base sha256:abc123... \
+     --target sha256:def456... \
+     --feed-snapshot sha256:feed789... \
+     --policy sha256:policy012...
+   ```
+3. Compare the determinism hash
+
+## Role-Based Views
+
+### Developer View (Default)
+
+Focus: What do I need to fix?
+
+- **Default Tab**: Actionables
+- **Visible**: Upgrade suggestions, witness paths
+- **Hidden**: Detailed attestations, policy internals
+
+### Security View
+
+Focus: Are the security claims valid?
+
+- **Default Tab**: Claims/VEX
+- **Visible**: VEX merge, policy reasoning, claim sources
+- **Hidden**: Low-level attestation details
+
+### Audit View
+
+Focus: Can I verify these claims?
+
+- **Default Tab**: Attestations
+- **Visible**: Signatures, replay commands, evidence pack
+- **Hidden**: Actionables (read-only mode)

+| `Esc` | Close expanded detail |
+| `C` | Copy replay command |
+| `E` | Export menu |
+
+## Troubleshooting
+
+### "No baseline available"
+
+The system couldn't find a suitable baseline because:
+- This is the first scan of this image
+- No previous scans passed policy gates
+
+**Solution**: Use "Custom" to manually select any previous scan.
+
+### "Stale feed warning"
+
+The vulnerability feed is more than 24 hours old.
+
+**Impact**: New CVEs may not be reflected in the comparison.
+
+**Solution**:
+1. Trigger a feed refresh
+2. Re-run comparison after refresh
+
+### "Signature verification failed"
+
+The DSSE envelope signature couldn't be verified.
+
+**Causes**:
+- Key rotation occurred
+- Attestation was modified
+- Network issue fetching public key
+
+**Solution**:
+1. Check if keys were recently rotated
+2. Try offline verification with local key
+3. Contact security team if persistent

+# StellaOps Triage UI Reducer Spec (Pure State + Explicit Commands)
+
+## 0. Purpose
+
+Define a deterministic, testable UI state machine for triage UI surfaces:
+
+- State transitions are pure functions.
+- Side effects are emitted as explicit commands.
+- Enables UI replay for debugging (aligns with StellaOps determinism and replay ethos).
+
+Target stack: Angular v17 + TypeScript.
+
+## 1. Core Concepts
+
+- **Action:** user/system event (route change, button click, HTTP success).
+- **State:** all data required to render triage surfaces.
+- **Command:** side-effect request (HTTP, download, navigation).
+
+Reducer signature:
+
+```ts
+type ReduceResult = { state: TriageState; cmd: Command };
+function reduce(state: TriageState, action: Action): ReduceResult;
+```
+
+## 2. State Model
+
+```ts
+export type Lane =
+  | "ACTIVE"
+  | "BLOCKED"
+  | "NEEDS_EXCEPTION"
+  | "MUTED_REACH"
+  | "MUTED_VEX"

+  | { type: "DOWNLOAD"; url: string }
+  | { type: "NAVIGATE"; route: TriageState["route"] };
+```
+
+## 4. Actions (Minimum Set)
+
+Action unions will evolve, but should include:
+
+- routing actions (`ROUTE_TABLE`, `ROUTE_CASE`)
+- table load and filter actions (`TABLE_LOAD`, `TABLE_LOAD_OK/ERR`, filter updates)
+- case load and nested resource actions (header/evidence/decisions/snapshots/diff)
+- decision drawer open/close and decision create/revoke actions
+- bundle export actions
+
+## 5. Determinism Requirements
+
+- Reducer must be pure (no global mutation, time access, randomness).
+- All derived URLs must be deterministic for a given state.
+- ETag/If-None-Match should be supported to reduce payload churn and improve sealed-mode behavior.
+
+## 6. Unit Testing Requirements
+
+Minimum tests:
+
+- Reducer purity: no external effects.
+- `TABLE_LOAD` produces correct URL for filters.
+- `ROUTE_CASE` triggers case header load.
+- `CASE_LOAD_OK` triggers evidence load (and the integration layer triggers other nested loads deterministically).
+- `DECISION_CREATE_OK` closes drawer and refreshes case header.
+- `BUNDLE_EXPORT_OK` emits `DOWNLOAD`.
+
+Recommended:
+
+- Golden state snapshots to ensure backwards compatibility when the state model evolves.

+# StellaOps Triage UX Guide (Narrative-First + Proof-Linked)
+
+## 0. Scope
+
+This guide specifies the user experience for StellaOps triage and evidence workflows:
+
+- Narrative-first case view that answers the three operator questions quickly.
+- Proof-linked evidence surfaces (SBOM/VEX/provenance/reachability/replay).
+- Quiet-by-default noise controls with reversible, signed decisions.
+- Smart-diff history that explains meaningful risk changes.
+
+Architecture constraints:
+
+- Lattice/risk evaluation executes in `scanner.webservice`.
+- `concelier` and `excititor` preserve per-source provenance (every merged/pruned datum remains traceable to origin).
+
+## 1. UX Contract
+
+Every triage surface must answer, in order:
+
+1) Can I ship this?
+2) If not, what exactly blocks me?
+3) What's the minimum safe change to unblock?
+
+Everything else is secondary and should be progressively disclosed.
+
+## 2. Primary Objects in the UX
+
+- Finding/Case: a specific vuln/rule tied to an asset (image/artifact/environment).
+- Risk Result: deterministic lattice output (score/verdict/lane), computed by `scanner.webservice`.
+- Evidence Artifact: signed, hash-addressed proof objects (SBOM slice, VEX doc, provenance, reachability slice, replay manifest).
+- Decision: reversible user/system action that changes visibility/gating (mute/ack/exception) and is always signed/auditable.
+- Snapshot: immutable record of inputs/outputs hashes enabling smart-diff.
+
+## 3. Global UX Principles
+
+### 3.1 Narrative-first, list-second
+
+Default view is a case narrative header plus an evidence rail. Lists exist for scanning and sorting, but not as the primary cognitive surface.
+
+### 3.2 Time-to-evidence target
+
+From pipeline alert click -> human-readable verdict + first evidence link:
+
+- p95 <= 30 seconds (including auth and initial fetch)
+- evidence is always one click away (no deep tab chains)
+
+### 3.3 Proof-linking is mandatory
+
+Any chip/badge that asserts a fact must link to the exact evidence object(s) that justify it.
+
+Examples:
+
+- "Reachable: Yes" -> call-stack slice and/or runtime hit record
+- "VEX: not_affected" -> effective VEX assertion plus signature details
+- "Blocked by Policy Gate X" -> policy artifact plus lattice explanation
+
+### 3.4 Quiet by default, never silent
+
+Muted lanes are hidden by default but surfaced with counts and a toggle. Muting never deletes; it creates a signed decision with TTL/reason and is reversible.
+
+### 3.5 Deterministic and replayable
+
+Users must be able to export an evidence bundle containing:
+
+- scan replay manifest (feeds/rules/policies/hashes)
+- signed artifacts
+- outputs (risk result, snapshots)
+
+so auditors can replay identically.
+
+## 4. Information Architecture
+
+### 4.1 Screens
+
+1) Findings table (global)
+
+- purpose: scan, sort, filter, jump into cases
+- default: muted lanes hidden
+- banner: shows count of auto-muted by policy with a "Show" toggle
+
+2) Case view (single-page narrative)
+
+- purpose: decision making plus proof review
+- above fold: verdict + chips + deterministic score
+- right rail: evidence list
+- tabs (max 3):
+  - Evidence (default)
+  - Reachability & Impact
+  - History (smart-diff)
+
+3) Export / verify bundle
+
+- purpose: offline/audit verification
+- async export job, then download DSSE-signed bundle when enabled
+- verification UI: signature status, hash tree, issuer chain
+
+### 4.2 Lanes (visibility buckets)
+
+Lanes are a UX categorization derived from deterministic risk plus decisions:
+
+- ACTIVE
+- BLOCKED
+- NEEDS_EXCEPTION
+- MUTED_REACH (non-reachable)
+- MUTED_VEX (effective VEX says not_affected)
+- COMPENSATED (controls satisfy policy)
+
+Default: show ACTIVE/BLOCKED/NEEDS_EXCEPTION. Muted lanes appear behind a toggle and via the banner counts.
+
+## 5. Case View Layout (Required)
+
+### 5.1 Top Bar
+
+- Asset name / image tag / environment
+- Last evaluated time
+- Policy profile name (e.g., "Strict CI Gate")
+
+### 5.2 Verdict Banner (Above fold)
+
+Large, unambiguous verdict:
+
+- SHIP
+- BLOCKED
+- NEEDS EXCEPTION
+
+Below verdict:
+
+- One-line "why" summary (max ~140 chars), e.g. "Reachable path observed; exploit signal present; Policy 'prod-strict' blocks."
+
+### 5.3 Chips (Each chip is clickable)
+
+Minimum set:
+
+- Reachability: Reachable / Not reachable / Unknown (with confidence)
+- Effective VEX: affected / not_affected / under_investigation
+- Exploit signal: yes/no + source indicator
+- Exposure: internet-exposed yes/no (if available)
+- Asset tier: tier label
+- Gate: allow/block/exception-needed (policy gate name)
+
+Chip click behavior:
+
+- opens evidence panel anchored to the proof objects
+- shows source chain (concelier/excititor preserved sources)
+
+### 5.4 Evidence Rail (Always visible right side)
+
+List of evidence artifacts with:
+
+- type icon
+- title
+- issuer
+- signed/verified indicator
+- short content digest
+- created timestamp
+
+Actions per item:
+
+- preview
+- copy digest
+- open raw
+- "show in bundle" marker
+
+### 5.5 Actions Footer (Only primary actions)
+
+- create work item
+- acknowledge / mute (opens decision drawer)
+- propose exception (decision with TTL plus approver chain)
+- export evidence bundle
+
+No more than 4 primary buttons. Secondary actions go into a menu.
+
+## 6. Decision Flows (Mute/Ack/Exception)
+
+### 6.1 Decision Drawer (common UI)
+
+Fields:
+
+- decision kind: mute reach / mute VEX / acknowledge / exception
+- reason code (dropdown) plus free-text note
+- TTL (required for exceptions; optional for mutes)
+- policy ref (auto-filled; editable only by admins)
+- sign and apply (server-side signing where enabled; user identity included)
+
+On submit:
+
+- create decision (audited)
+- re-evaluate lane/verdict if applicable
+- create snapshot ("DECISION" trigger)
+- show toast with undo link
+
+### 6.2 Undo
+
+Undo is implemented as "revoke decision" (signed revoke record or revocation fields). Never delete.
+
+## 7. Smart-Diff UX
+
+### 7.1 Timeline
+
+Chronological snapshots:
+
+- when (timestamp)
+- trigger (feed/vex/sbom/policy/runtime/decision/rescan)
+- summary (short)
+
+### 7.2 Diff panel
+
+Two-column diff:
+
+- inputs changed (with proof links): VEX assertion changed, policy version changed, runtime trace arrived, etc.
+- outputs changed: lane, verdict, score, gates
+
+### 7.3 Meaningful change definition
+
+The UI only highlights meaningful changes:
+
+- verdict change
+- lane change
+- score crosses a policy threshold
+- reachability state changes
+- effective VEX status changes
+
+Other changes remain in expandable details.
+
+## 8. Performance & UI Engineering Requirements
+
+- findings table uses virtual scroll and server-side pagination
+- case view loads in 2 steps:
+  1) header narrative (small payload)
+  2) evidence list plus snapshots (lazy)
+- evidence previews are lazy-loaded and cancellable
+- use ETag/If-None-Match for case and evidence list endpoints
+- UI must remain usable under high latency (air-gapped / offline kits):
+  - show cached last-known verdict with a clear "stale" marker
+  - allow exporting bundles from cached artifacts when permissible
+
+## 9. Accessibility & Operator Usability
+
+- keyboard navigation: table rows, chips, evidence list
+- high contrast mode supported
+- all status is conveyed by text + shape (not color only)
+- copy-to-clipboard for digests, purls, CVE IDs
+
+## 10. Telemetry (Must instrument)
+
+- TTFS: notification click -> verdict banner rendered
+- time-to-proof: click chip -> proof preview shown
+- mute reversal rate (auto-muted later becomes actionable)
+- bundle export success/latency
+
+## 11. Responsibilities by Service
+
+- `scanner.webservice`:
+  - produces reachability results, risk results, snapshots
+  - stores/serves case narrative header, evidence indexes, smart-diff
+- `concelier`:
+  - aggregates vuln feeds and preserves per-source provenance
+- `excititor`:
+  - merges VEX and preserves original assertion sources
+- `notify.webservice`:
+  - emits first_signal / risk_changed / gate_blocked
+- `scheduler.webservice`:
+  - re-evaluates existing images on feed/policy updates, triggers snapshots

+# Console Tenant Administration
+
+This document describes tenant administration workflows in the Console: creating tenants, managing access, and operating safely in multi-tenant deployments.
+
+## Tenant Lifecycle
+
+Typical tenant operations:
+
+- Create and deactivate tenants
+- Configure tenant identity and display attributes (name, tags)
+- Review tenant-level configuration and capabilities (feature exposure is configuration-driven)
+
+## Access Control
+
+Tenant administration typically includes:
+
+- Role assignment (who can operate vs approve vs audit)
+- Scope allocation (what each role is allowed to do)
+- Optional ABAC filters (environment/project constraints)
+
+See:
+
+- `docs/security/scopes-and-roles.md`
+- `docs/security/tenancy-overview.md`
+- `docs/architecture/console-admin-rbac.md`
+
+## Safety and Auditability
+
+- All admin actions must be auditable (who, what, when, tenant).
+- Prefer reversible operations:
+  - deactivate instead of delete
+  - rotate credentials instead of reusing
+- Make tenant context explicit in the UI to avoid cross-tenant mistakes.
+
+## Offline / Air-Gap Notes
+
+- Admin actions should remain available in sealed-mode, but any import/export should be explicit and verified.
+- When operating from Offline Kit snapshots, show snapshot identity and staleness for admin-relevant views (feeds, policies, issuer trust).
+
+## References

+# Console Air-Gap UX (Sealed Mode)
+
+This document describes the Console surfaces and operator expectations when running against Offline Kit snapshots or in sealed/air-gapped deployments.
+
+## Goals
+
+- Make offline operation explicit (never “pretend online”).
+- Show snapshot identity and staleness budgets so operators can reason about freshness.
+- Keep import workflows auditable and tenant-scoped.
+
+## Required Surfaces
+
+### Offline / Sealed Status Badge
+
+The Console should surface:
+
+- Whether the site is operating in **sealed/offline mode**.
+- The current **snapshot identity** (bundle ID / generation / content digest).
+- The **last import time** and configured freshness/staleness budgets.
+
+### Import Workflow
+
+When imports are supported via Console:
+
+- Use a clear stepper flow: select bundle → verify → apply → confirm.
+- Display verification results (signature status, digest) without exposing secrets.
+- Emit an auditable event: who imported what, when, and which snapshot became active.
+
+### Staleness Dashboard
+
+Operators need a quick view of:
+
+- Advisory/VEX/policy ages relative to configured budgets
+- Tenants/environments nearing expiry thresholds
+- “Why stale?” explanations (missing time anchor, expired bundle, etc.)
+
+## Staleness Rules
+
+- Treat staleness as **a first-class signal**: show it prominently when it affects decision confidence.
+- Use UTC timestamps; avoid local time ambiguity.
+- When a time anchor is missing, surface “unknown staleness” instead of silently defaulting.
+
+## Security and Guardrails
+
+- Import is an admin operation (scoped and audited).
+- Always display tenant context for imports and status surfaces.
+- Avoid displaying long hashes without context; prefer short digests with a “copy full digest” action.
+

+# Attestor UI (Console)
+
+The Console includes surfaces for viewing and verifying attestations produced by StellaOps services.
+
+## Views
+
+- **Attestation list:** filter by tenant, issuer, predicate/type, verification status.
+- **Attestation detail:** show subject, predicate, timestamps, signer identity, and verification outcome.
+- **Verification panel:** signature status, certificate chain/key identity, and transparency proof (when configured).
+
+## Actions
+
+- Download DSSE envelope (and referenced artifacts where applicable)
+- Copy digests and correlation IDs for audit trails
+- Open transparency proof details (when enabled)
+
+## Guardrails
+
+- The UI must not “derive” verdicts from attestations; it should display verification state and referenced evidence.
+- Tenancy must always be explicit; exports should preserve tenant context and verification metadata.

+# Console Forensics and Evidence Review
+
+This document describes how the Console supports forensic review of decisions: timelines, evidence viewing, attestation verification, and audit exports.
+
+## Timeline Explorer
+
+The timeline view should enable:
+
+- Filtering by tenant, artifact, finding, and time window
+- Drill-down from a verdict to its evidence objects (SBOM slice, VEX observation/linkset, reachability proof, policy explain trace)
+- Visibility into operator actions (triage actions, exceptions, approvals) as append-only events
+
+## Evidence Viewer
+
+Evidence viewing should prioritize:
+
+- Clear provenance (issuer identity, timestamps, digests)
+- Verification state (signature verified/failed/unknown)
+- Deterministic identifiers so auditors can replay and compare
+
+## Attestation Verification
+
+When presenting attestations (DSSE/in-toto):
+
+- Display verification status and key identity
+- Link to transparency log proof when configured
+- Allow exporting the DSSE envelope and the referenced artifacts
+
+## Export / Verify Workflows
+
+Exports are the bridge between online and offline review:
+
+- Exports should be deterministic (stable ordering, UTC timestamps).
+- Export bundles should include integrity metadata (digests) so offline reviewers can verify without trusting a live service.
+

+# Console Observability
+
+This document describes Console observability expectations: what telemetry matters, how to correlate UI actions with backend traces, and what to surface in air-gapped deployments.
+
+## What to Measure (UI)
+
+Recommended UI metrics include:
+
+- **Time-to-verdict (TTFV):** from navigation to verdict banner rendered.
+- **Time-to-evidence:** from clicking a fact/badge to evidence preview available.
+- **Export latency and success rate:** evidence bundle generation time and failures.
+- **Mute/exception usage:** how often operators suppress or escalate findings (counts, reversal rate).
+
+## What to Log (Structured)
+
+Console logs should be structured and tenant-scoped:
+
+- `tenantId`, `actor`, `actionType`
+- `artifactId` / image digest
+- `findingId` / vulnerability identifiers (when relevant)
+- `traceId` / correlation IDs that tie UI requests to backend traces
+
+## Error Surfaces
+
+Operators need actionable error messaging:
+
+- Distinguish client validation errors from server failures.
+- Provide a copyable correlation/trace ID for support.
+- Avoid leaking stack traces or secrets into UI notifications.
+
+## Offline / Sealed Mode Telemetry
+
+In sealed mode, surface:
+
+- snapshot identity and staleness budgets
+- which data is stale vs fresh (policy pack version, VEX snapshot time, feed ages)
+
+## References

+# Console Risk UI (Overview)
+
+This document describes how risk and explainability concepts should surface in the Console.
+
+## Concepts to Surface
+
+- **Verdict and “why”:** a short, narrative explanation above the fold.
+- **Evidence rail:** links to proofs that justify each fact (SBOM, VEX, reachability, policy explain trace).
+- **Risk signals:** severity, exploit signals, exposure context, and confidence/uncertainty indicators.
+
+## Explainability Expectations
+
+- Every blocking decision must link to the policy gate and the evidence inputs that triggered it.
+- Uncertainty must remain explicit (avoid false safety when evidence is missing or conflicts exist).
