# Sprint Series 20260106_003 - Verifiable Software Supply Chain Pipeline
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This sprint series completes the "quiet, verifiable software supply chain pipeline" as outlined in the product advisory. While StellaOps already implements ~85% of the advisory requirements, this series addresses the remaining gaps to deliver a fully integrated, production-ready pipeline from SBOMs to signed evidence bundles.
|
||||
|
||||
## Problem Statement
|
||||
|
||||
The product advisory outlines a complete software supply chain pipeline with:
|
||||
- Deterministic per-layer SBOMs with normalization
|
||||
- VEX-first gating to reduce noise before triage
|
||||
- DSSE/in-toto attestations for everything
|
||||
- Traceable event flow with breadcrumbs
|
||||
- Portable evidence bundles for audits
|
||||
|
||||
**Current State Analysis:**
|
||||
|
||||
| Capability | Status | Gap |
|
||||
|------------|--------|-----|
|
||||
| Deterministic SBOMs | 95% | Per-layer files not exposed, Composition Recipe API missing |
|
||||
| VEX-first gating | 75% | No explicit "gate" service that blocks/warns before triage |
|
||||
| DSSE attestations | 90% | Per-layer attestations missing, cross-attestation linking missing |
|
||||
| Evidence bundles | 85% | No standardized export format with verify commands |
|
||||
| Event flow | 90% | Router idempotency enforcement not formalized |
|
||||
|
||||

## Key Deliverables
|
||||
|
||||
### Sprint 003_001: Per-layer SBOM & Composition Recipe API
|
||||
- Per-layer CycloneDX/SPDX files stored separately in CAS
|
||||
- `GET /scans/{id}/layers/{digest}/sbom` API endpoint
|
||||
- `GET /scans/{id}/composition-recipe` API endpoint
|
||||
- Deterministic layer ordering with Merkle root in recipe
|
||||
- CLI: `stella scan sbom --layer <digest> --format cdx|spdx`
|
||||
|
||||
### Sprint 003_002: VEX Gate Service
|
||||
- `IVexGateService` interface with gate decisions: `PASS`, `WARN`, `BLOCK`
|
||||
- Pre-triage filtering that reduces noise
|
||||
- Evidence tracking for each gate decision
|
||||
- Integration with Excititor VEX observations
|
||||
- Configurable gate policies (exploitable+reachable+no-control = BLOCK)
|
||||
|
||||
### Sprint 003_003: Evidence Bundle Export
|
||||
- Standardized export format: `evidence-bundle-<id>.tar.gz`
|
||||
- Contents: SBOMs, VEX statements, attestations, public keys, README
|
||||
- `verify.sh` script embedded in bundle
|
||||
- `stella evidence export --bundle <id> --output ./audit-bundle.tar.gz`
|
||||
- Offline verification support
|
||||
|
||||
### Sprint 003_004: Cross-Attestation Linking
|
||||
- SBOM attestation links to VEX attestation via subject reference
|
||||
- Policy verdict attestation links to both
|
||||
- Per-layer attestations with layer-specific subjects
|
||||
- `GET /attestations?artifact=<digest>&chain=true` for full chain retrieval
|
||||
|
||||
## Acceptance Criteria (Series)
|
||||
|
||||
1. **Determinism**: Same inputs produce identical SBOMs, recipes, and attestation hashes
|
||||
2. **Traceability**: Any artifact can be traced through the full pipeline via digest
|
||||
3. **Verifiability**: Evidence bundles can be verified offline without network access
|
||||
4. **Completeness**: All artifacts (SBOMs, VEX, verdicts, attestations) are included in bundles
|
||||
5. **Integration**: VEX gate reduces triage noise by at least 50% (measured via test corpus)
|
||||
|
||||
## Risk Assessment
|
||||
|
||||
| Risk | Impact | Mitigation |
|
||||
|------|--------|------------|
|
||||
| Per-layer SBOMs increase storage | Medium | Content-addressable deduplication, TTL for stale layers |
|
||||
| VEX gate false positives | High | Conservative defaults, policy override mechanism |
|
||||
| Cross-attestation circular deps | Low | DAG validation at creation time |
|
||||
| Export bundle size | Medium | Compression, selective export by date range |
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
- **Unit tests**: Each service with determinism verification
|
||||
- **Integration tests**: Full pipeline from scan to export
|
||||
- **Replay tests**: Identical inputs produce identical outputs
|
||||
- **Corpus tests**: Advisory test corpus for VEX gate accuracy
|
||||
- **E2E tests**: Air-gapped verification of exported bundles
|
||||
|
||||
## Documentation Updates Required
|
||||
|
||||
- `docs/modules/scanner/architecture.md` - Per-layer SBOM section
|
||||
- `docs/modules/evidence-locker/architecture.md` - Export bundle format
|
||||
- `docs/modules/attestor/architecture.md` - Cross-attestation linking
|
||||
- `docs/API_CLI_REFERENCE.md` - New endpoints and commands
|
||||
- `docs/OFFLINE_KIT.md` - Evidence bundle verification
|
||||
|
||||
## Related Work
|
||||
|
||||
- SPRINT_20260105_002_* (HLC) - Required for timestamp ordering in attestation chains
|
||||
- SPRINT_20251229_001_002_BE_vex_delta - VEX delta foundation
|
||||
- Epic 10 (Export Center) - Bundle export workflows
|
||||
- Epic 19 (Attestor Console) - Attestation verification UI
|
||||
|
||||
## Execution Notes
|
||||
|
||||
- All changes must maintain backward compatibility
|
||||
- Feature flags for gradual rollout recommended
|
||||
- Cross-module changes require coordinated deployment
|
||||
- CLI commands should support both new and legacy formats during transition

|

## Objective
|
||||
|
||||
Expose per-layer SBOMs as first-class artifacts and add a Composition Recipe API that enables downstream verification of SBOM determinism. This completes Step 1 of the product advisory: "Deterministic SBOMs (per layer, per build)".
|
||||
|
||||
## Context
|
||||
|
||||
**Current State:**
|
||||
- `LayerComponentFragment` model tracks components per layer internally
|
||||
- SBOM composition aggregates fragments into single image-level SBOM
|
||||
- Composition recipe stored in CAS but not exposed via API
|
||||
- No mechanism to retrieve SBOM for a specific layer
|
||||
|
||||
**Target State:**
|
||||
- Per-layer SBOMs stored as individual CAS artifacts
|
||||
- API endpoints to retrieve layer-specific SBOMs
|
||||
- Composition Recipe API for determinism verification
|
||||
- CLI support for per-layer SBOM export
|
||||
|
||||

## CLI Commands
|
||||
|
||||
```bash
|
||||
# List layers with SBOM info
|
||||
stella scan layers <scan-id>
|
||||
|
||||
# Get per-layer SBOM
|
||||
stella scan sbom <scan-id> --layer sha256:abc123 --format cdx --output layer.cdx.json
|
||||
|
||||
# Get composition recipe
|
||||
stella scan recipe <scan-id> --output recipe.json
|
||||
|
||||
# Verify composition recipe against stored SBOMs
|
||||
stella scan recipe <scan-id> --verify
|
||||
```
|
||||
|
||||
## Storage Schema
|
||||
|
||||
Per-layer SBOMs stored in CAS with paths:
|
||||
```
|
||||
/evidence/sboms/<image-digest>/layers/<layer-digest>.cdx.json
|
||||
/evidence/sboms/<image-digest>/layers/<layer-digest>.spdx.json
|
||||
/evidence/sboms/<image-digest>/recipe.json
|
||||
```
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
1. **Determinism**: Same image scan produces identical per-layer SBOMs
|
||||
2. **Completeness**: Every layer in the image has a corresponding SBOM
|
||||
3. **Verifiability**: Composition recipe Merkle root matches layer SBOM digests
|
||||
4. **Performance**: Per-layer SBOM retrieval < 100ms (cached)
|
||||
5. **Backward Compatibility**: Existing SBOM APIs continue to work unchanged
|
||||
|
||||
## Test Cases
|
||||
|
||||
### Unit Tests
|
||||
- `LayerSbomWriter` produces deterministic output for identical fragments
|
||||
- Composition recipe Merkle root computation is RFC 6962 compliant
|
||||
- Layer ordering is stable (sorted by layer order, not discovery order)
|
||||
|
||||
### Integration Tests
|
||||
- Full scan produces per-layer SBOMs stored in CAS
|
||||
- API returns correct layer SBOM by digest
|
||||
- Recipe verification passes for valid scans
|
||||
- Recipe verification fails for tampered SBOMs
|
||||
|
||||
### Determinism Tests
|
||||
- Two scans of identical images produce identical per-layer SBOM digests
|
||||
- Composition recipe is identical across runs
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Store per-layer SBOMs in CAS | Content-addressable deduplication handles shared layers |
|
||||
| Use layer digest as key | Deterministic, unique per layer content |
|
||||
| Include both CDX and SPDX per layer | Supports customer format preferences |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Storage growth with many layers | TTL-based cleanup for orphaned layer SBOMs |
|
||||
| Cache invalidation complexity | Layer SBOMs are immutable once created |
|
||||

|
||||
|
||||
## Objective
|
||||
|
||||
Implement a VEX-first gating service that filters vulnerability findings before triage, reducing noise by applying VEX statements and configurable policies. This completes Step 2 of the product advisory: "VEX-first gating (reduce noise before triage)".
|
||||
|
||||
## Context
|
||||
|
||||
**Current State:**
|
||||
- Excititor ingests VEX statements and stores as immutable observations
|
||||
- VexLens computes consensus across weighted statements
|
||||
- Scanner produces findings without pre-filtering
|
||||
- No explicit "gate" decision before findings reach triage queue
|
||||
|
||||
**Target State:**
|
||||
- `IVexGateService` applies VEX evidence before triage
|
||||
- Gate decisions: `PASS` (proceed), `WARN` (proceed with flag), `BLOCK` (requires attention)
|
||||
- Evidence tracking for each gate decision
|
||||
- Configurable gate policies per tenant
|
||||
|
||||

## API Endpoints
|
||||
|
||||
### GET /api/v1/scans/{scanId}/gate-results
|
||||
|
||||
```json

|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## CLI Commands
|
||||
|
||||
```bash
|
||||
# Show current gate policy
|
||||
stella scan gate-policy show
|
||||
|
||||
# Get gate results for a scan
|
||||
stella scan gate-results <scan-id>
|
||||
|
||||
# Get gate results with blocked only
|
||||
stella scan gate-results <scan-id> --decision Block
|
||||
|
||||
# Run scan with gate bypass (emergency)
|
||||
stella scan start <image> --bypass-gate
|
||||
```
|
||||
|
||||
## Performance Targets
|
||||
|
||||
| Metric | Target |
|
||||
|--------|--------|
|
||||
| Gate evaluation throughput | >= 1000 findings/sec |
|
||||
| VEX lookup latency (cached) | < 5ms |
|
||||
| VEX lookup latency (uncached) | < 50ms |
|
||||
| Memory overhead per scan | < 10MB for gate state |
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
1. **Noise Reduction**: Gate reduces triage queue by >= 50% on test corpus
|
||||
2. **Accuracy**: False positive rate < 1% (findings incorrectly passed)
|
||||
3. **Performance**: Gate evaluation < 1s for typical scan (100 findings)
|
||||
4. **Traceability**: Every gate decision has auditable evidence
|
||||
5. **Configurability**: Policy rules can be customized per tenant
|
||||
|
||||
## Test Cases
|
||||
|
||||
### Unit Tests
|
||||
- Policy rule matching logic for all conditions
|
||||
- Default policy produces expected decisions
|
||||
- Evidence is correctly captured from VEX statements
|
||||
|
||||
### Integration Tests
|
||||
- Gate service queries Excititor correctly
|
||||
- Scan pipeline applies gate decisions
|
||||
- Gate results appear in API response
|
||||
|
||||
### Corpus Tests (test data from `src/__Tests/__Datasets/`)
|
||||
- Known "not affected" CVEs are passed
|
||||
- Known exploitable+reachable CVEs are blocked
|
||||
- Ambiguous cases are warned
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Gate after findings, before triage | Allows full finding context for decision |
|
||||
| Default to Warn not Block | Conservative to avoid blocking legitimate alerts |
|
||||
| Cache VEX lookups with short TTL | Balance freshness vs performance |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| VEX data stale at gate time | TTL-based cache invalidation, async refresh |
|
||||
| Policy misconfiguration | Policy validation at startup, audit logging |
|
||||
| Gate becomes bottleneck | Parallel evaluation, batch VEX lookups |
|
||||

||||

| 2026-01-06 | Claude | Sprint created from product advisory |
|
||||
| 2026-01-06 | Claude | Implemented Phase 1: VEX Gate Core Service (T001-T008) - created StellaOps.Scanner.Gate library with VexGateDecision, VexGateResult, VexGatePolicy, VexGateService, and comprehensive unit tests |
|
||||
| 2026-01-06 | Claude | Implemented Phase 2: Excititor Integration (T009-T013) - created IVexObservationQuery, CachingVexObservationProvider (bounded cache, batch prefetch), VexGateExcititorAdapter (data source bridge), VexTypes (local enums). All 28 tests passing. T014 (perf benchmarks) deferred to production load testing. |
|
||||
| 2026-01-06 | Claude | Implemented Phase 3: Scanner Worker Integration (T015-T018) - created VexGateStageExecutor, ScanStageNames.VexGate, ScanAnalysisKeys for gate results, IScanMetricsCollector interface, VexGateStageOptions.Bypass for emergency scans. T019 BLOCKED due to pre-existing Scanner.Worker build issues (missing StellaOps.Determinism.Abstractions and other deps). |
|
||||
| 2026-01-06 | Claude | Implemented Phase 4: Gate Evidence & API (T020-T024) - created VexGateContracts.cs (API DTOs), VexGateController.cs (REST endpoints), IVexGateQueryService.cs + VexGateQueryService.cs (query service with in-memory store), VexGateAuditLogger.cs (compliance audit logging), added VexGateSummaryPayload to ScanCompletedEventPayload. T025 deferred to WebService test infrastructure. |
|
||||
| 2026-01-07 | Claude | UNBLOCKED T019: Fixed Scanner.Worker build by adding project reference to StellaOps.Scanner.Gate; fixed CycloneDxLayerWriter.cs to use SpecificationVersion.v1_6 (v1_7 not yet in CycloneDX.Core 10.x) |
|
||||
| 2026-01-07 | Claude | Completed T019: Created VexGateStageExecutorTests.cs with 15 comprehensive tests covering: stage name, bypass mode, no-findings scenarios, gate decisions (pass/warn/block), result storage, policy version, metrics recording, cancellation propagation, argument validation. Used TestJobLease pattern for ScanJobContext creation. All tests passing. |
|
||||
| 2026-01-07 | Claude | Completed T026-T027: Created VexGateScanCommandGroup.cs with two CLI commands: `stella scan gate-policy show` (displays current VEX gate policy) and `stella scan gate-results <scan-id>` (shows gate decisions for a scan). Commands use Scanner API via BackendUrl or STELLAOPS_SCANNER_URL env var. |
|
||||
| 2026-01-07 | Claude | Completed T028: Created etc/scanner.vexgate.yaml.sample with comprehensive VEX gate configuration including rules, caching, audit, metrics, and bypass settings. Created VexGateOptions.cs (configuration model with IValidatableObject) and VexGateServiceCollectionExtensions.cs (DI registration with ValidateOnStart). |
|
||||
| 2026-01-07 | Claude | Completed T014: Created StellaOps.Scanner.Gate.Benchmarks project with 6 BenchmarkDotNet benchmarks for policy evaluation: single finding, batch 100, batch 1000, no rule match (worst case), first rule match (best case), diverse mix. |
|
||||
| 2026-01-07 | Claude | Completed T025: Created VexGateEndpointsTests.cs with 9 integration tests for VEX gate API endpoints (GET gate-policy, gate-results, gate-summary, gate-blocked) using WebApplicationFactory and mock IVexGateQueryService. All tests passing. |
|
||||
| 2026-01-07 | Claude | Completed T029: Created VexGateCommandTests.cs with 14 unit tests for VEX gate CLI commands (gate-policy show, gate-results). Tests cover command structure, options (-t, -o, -v, -s, -d, -l), required options, and command hierarchy. Added -t and -l short aliases to VexGateScanCommandGroup.cs. All tests passing. |

|
||||
## Objective
|
||||
|
||||
Implement a standardized evidence bundle export format that includes SBOMs, VEX statements, attestations, public keys, and embedded verification scripts. This enables offline audits and air-gapped verification as specified in the product advisory MVP: "Evidence Bundle export (zip/tar) for audits".
|
||||
|
||||
## Context
|
||||
|
||||
**Current State:**
|
||||
- EvidenceLocker stores sealed bundles with Merkle integrity
|
||||
- Bundles contain SBOM, scan results, policy verdicts, attestations
|
||||
- No standardized export format for external auditors
|
||||
- No embedded verification commands
|
||||
|
||||
**Target State:**
|
||||
- Standardized `evidence-bundle-<id>.tar.gz` export format
|
||||
- Embedded `verify.sh` and `verify.ps1` scripts
|
||||
- README with verification instructions
|
||||
- Public keys bundled for offline verification
|
||||
- CLI command for export

|
||||
|
||||
```
|
||||
Response 200 (when ready):
|
||||
Headers:
|
||||
Content-Type: application/gzip
|
||||
Content-Disposition: attachment; filename="evidence-bundle-eb-123.tar.gz"
|
||||
Body: <binary tar.gz content>
|

"status": "processing",
|
||||
"progress": 65,
|
||||
"estimatedTimeRemaining": "30s"
|
||||
}
|
||||
```
|
||||
|
||||
## CLI Commands
|
||||
|
||||
```bash
|
||||
# Export bundle to file
|
||||
stella evidence export --bundle eb-2026-01-06-abc123 --output ./audit-bundle.tar.gz
|
||||
|
||||
# Export with options
|
||||
stella evidence export --bundle eb-123 \
|
||||
--output ./bundle.tar.gz \
|
||||
--include-layers \
|
||||
--include-rekor-proofs
|
||||
|
||||
# Verify an exported bundle
|
||||
stella evidence verify ./audit-bundle.tar.gz
|
||||
|
||||
# Verify offline (skip Rekor)
|
||||
stella evidence verify ./audit-bundle.tar.gz --offline
|
||||
```
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
1. **Completeness**: Bundle includes all specified artifacts (SBOMs, VEX, attestations, keys)
|
||||
2. **Verifiability**: `verify.sh` and `verify.ps1` run successfully on valid bundles
|
||||
3. **Offline Support**: Verification works without network access (except Rekor)
|
||||
4. **Determinism**: Same bundle exported twice produces identical tar.gz
|
||||
5. **Documentation**: README explains verification steps for non-technical auditors
|
||||
|
||||
## Test Cases
|
||||
|
||||
### Unit Tests
|
||||
- Manifest serialization is deterministic
|
||||
- Merkle root computation matches expected
|
||||
- Checksum file format is correct
|
||||
|
||||
### Integration Tests
|
||||
- Export service collects all artifacts from CAS
|
||||
- Generated verify.sh runs correctly on Linux
|
||||
- Generated verify.ps1 runs correctly on Windows
|
||||
- Large bundles (>100MB) export without OOM
|
||||
|
||||
### E2E Tests
|
||||
- Full flow: scan -> seal -> export -> verify
|
||||
- Exported bundle verifies in air-gapped environment
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| tar.gz format | Universal, works on all platforms |
|
||||
| Embedded verify scripts | No external dependencies for basic verification |
|
||||
| Include public keys in bundle | Enables offline verification |
|
||||
| NDJSON for audit timeline | Streaming-friendly, easy to parse |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Bundle size too large | Compression, optional layer SBOMs |
|
||||
| Script compatibility issues | Test on multiple OS versions |
|
||||
| Key rotation during export | Include all valid keys, document rotation |
|
||||

||||

| Title | Cross-Attestation Linking & Per-Layer Attestations |
|
||||
| Working Directory | `src/Attestor/` |
|
||||
| Dependencies | SPRINT_20260106_003_001, SPRINT_20260106_003_002 |
|

| Blocking | None |
|
||||
|
||||
## Objective
|
||||
|
||||
Implement cross-attestation linking (SBOM -> VEX -> Policy chain) and per-layer attestations to complete the attestation chain model specified in Step 3 of the product advisory: "Sign everything (portable, verifiable evidence)".
|
||||
|
||||
## Context
|
||||
|
||||
**Current State:**
|
||||
- Attestor creates DSSE envelopes for SBOMs, VEX, scan results, policy verdicts
|
||||
- Each attestation is independent with subject pointing to artifact digest
|
||||
- No explicit chain linking between attestations
|
||||
- Single attestation per image (no per-layer)
|
||||
|
||||
**Target State:**
|
||||
- Cross-attestation linking via in-toto layout references
|
||||
- Per-layer attestations with layer-specific subjects
|
||||
- Query API for attestation chains
|
||||
- Full provenance chain from source to final verdict
|
||||

||||

## CLI Commands
|
||||
|
||||
```bash
|
||||
# Get attestation chain for an artifact
|
||||
stella attest chain sha256:imageabc...
|
||||
|
||||
# Get chain as graph
|
||||
stella attest chain sha256:imageabc... --format mermaid
|
||||
|
||||
# List layer attestations for a scan
|
||||
stella attest layers <scan-id>
|
||||
|
||||
# Verify complete chain
|
||||
stella attest verify-chain sha256:imageabc...
|
||||
```
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
1. **Chain Completeness**: Policy attestation links to all upstream attestations
|
||||
2. **Per-Layer Coverage**: Every layer has its own attestation
|
||||
3. **Queryability**: Full chain retrievable from any node
|
||||
4. **Validation**: Circular references rejected at creation
|
||||
5. **Performance**: Chain resolution < 100ms for typical depth (5 levels)
|
||||
|
||||
## Test Cases
|
||||
|
||||
### Unit Tests
|
||||
- Chain builder creates correct DAG structure
|
||||
- Link validator detects circular references
|
||||
- Chain traversal respects depth limits
|
||||
|
||||
### Integration Tests
|
||||
- Full scan produces complete attestation chain
|
||||
- Chain query returns all linked attestations
|
||||
- Per-layer attestations stored correctly
|
||||
|
||||
### E2E Tests
|
||||
- End-to-end: scan -> gate -> attestation chain -> export
|
||||
- Chain verification in exported bundle
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Store links in separate table | Efficient traversal, no attestation mutation |
|
||||
| Use DAG not tree | Allows multiple parents (SBOM used by VEX and Policy) |
|
||||
| Batch layer attestations | Performance: one signing operation for all layers |
|
||||
| Materials field for links | in-toto standard compliance |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Chain resolution performance | Depth limit, caching, indexed traversal |
|
||||
| Circular reference bugs | Validation at insertion, periodic audit |
|
||||
| Orphaned attestations | Cleanup job for unlinked entries |
|
||||
|
||||

|
||||
| Advisory | `docs-archived/product-advisories/06-Jan-2026 - Quiet-by-Default Triage with Attested Exceptions.md` |
|
||||
|
||||
## Objective
|
||||
|
||||
Integrate the existing quiet-by-default triage backend APIs into the Angular 17 frontend. The backend infrastructure is complete; this sprint delivers the UX layer that enables users to experience "inbox shows only actionables" with one-click access to the Review lane and evidence export.
|
||||
|
||||
## Context
|
||||
|
||||
**Current State:**
|
||||
- Backend APIs fully implemented:
|
||||
- `GatingReasonService` computes gating status
|
||||
- `GatingContracts.cs` defines DTOs (`FindingGatingStatusDto`, `GatedBucketsSummaryDto`)
|
||||
- `ApprovalEndpoints` provides CRUD for approvals
|
||||
- `TriageStatusEndpoints` serves lane/verdict data
|
||||
- `EvidenceLocker` provides bundle export
|
||||
- Frontend has existing findings table but lacks:
|
||||
- Quiet/Review lane toggle
|
||||
- Gated bucket summary chips
|
||||
- Breadcrumb navigation
|
||||
- Approval workflow modal
|
||||
|
||||
**Target State:**
|
||||
- Default view shows only actionable findings (Quiet lane)
|
||||
- Banner displays gated bucket counts with one-click filters
|
||||
- Breadcrumb bar enables image->layer->package->symbol->call-path navigation
|
||||
- Decision drawer supports mute/ack/exception with signing
|
||||
- One-click evidence bundle export
|
||||
|
||||

@Input() finding!: FindingWithProvenance;
|

}
|

```
|
||||
|
||||
## Data Flow
|
||||
|
||||
```
|
||||
FindingsPage
|
||||
├── TriageLaneToggle (quiet/review selection)
|
||||
│ └── emits laneChange → updates query params
|
||||
├── GatedBucketChips (bucket counts)
|
||||
│ └── emits filterChange → adds gating reason filter
|
||||
├── FindingsTable (filtered list)
|
||||
│ └── rows show gating badge when applicable
|
||||
└── FindingDetailPanel (selected finding)
|
||||
├── VerdictBanner (SHIP/BLOCK/NEEDS_EXCEPTION)
|
||||
├── StatusChips (reachability, VEX, exploit, gate)
|
||||
│ └── click → opens evidence panel
|
||||
├── ProvenanceBreadcrumb (image→call-path)
|
||||
│ └── click → navigates to hop detail
|
||||
├── EvidenceRail (artifacts list)
|
||||
│ └── ExportEvidenceButton
|
||||
└── ActionsFooter
|
||||
└── DecisionDrawer (mute/ack/exception)
|
||||
```
|
||||
|
||||
## Styling Requirements
|
||||
|
||||
Per `docs/ux/TRIAGE_UX_GUIDE.md`:
|
||||
|
||||
- Status conveyed by text + shape (not color only)
|
||||
- High contrast mode supported
|
||||
- Keyboard navigation for table rows, chips, evidence list
|
||||
- Copy-to-clipboard for digests, PURLs, CVE IDs
|
||||
- Virtual scroll for findings table
|
||||
|
||||
## Telemetry (Required Instrumentation)
|
||||
|
||||
| Metric | Description |
|
||||
|--------|-------------|
|
||||
| `triage.ttfs` | Time from notification click to verdict banner rendered |
|
||||
| `triage.time_to_proof` | Time from chip click to proof preview shown |
|
||||
| `triage.mute_reversal_rate` | % of auto-muted findings that become actionable |
|
||||
| `triage.bundle_export_latency` | Evidence bundle export time |
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
1. **Default Quiet**: Findings list shows only non-gated (actionable) findings by default
|
||||
2. **One-Click Review**: Single click toggles to Review lane showing all gated findings
|
||||
3. **Bucket Visibility**: Gated bucket counts always visible, clickable to filter
|
||||
4. **Breadcrumb Navigation**: Click-through from image to call-path works end-to-end
|
||||
5. **Decision Persistence**: Mute/ack/exception decisions persist and show undo toast
|
||||
6. **Evidence Export**: Bundle downloads within 5 seconds for typical findings
|
||||
7. **Accessibility**: Keyboard navigation and high-contrast mode functional
|
||||
8. **Performance**: Findings list renders in <2s for 1000 findings (virtual scroll)
|
||||
|
||||
## Test Cases
|
||||
|
||||
### Unit Tests
|
||||
- Lane toggle emits correct events
|
||||
- Bucket chips render correct counts
|
||||
- Breadcrumb renders all path segments
|
||||
- Decision drawer validates required fields
|
||||
- Export button shows progress state
|
||||
|
||||
### Integration Tests
|
||||
- Lane toggle filters API calls correctly
|
||||
- Bucket click applies gating reason filter
|
||||
- Decision submission calls approval API
|
||||
- Export triggers bundle download
|
||||
|
||||
### E2E Tests
|
||||
- Full workflow: view findings -> toggle lane -> select finding -> view breadcrumb -> export evidence
|
||||
- Approval workflow: select finding -> open drawer -> submit decision -> verify toast -> verify persistence
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Default to Quiet lane | Reduces noise per advisory; Review always one click away |
|
||||
| Breadcrumb as separate component | Reusable across finding detail and evidence views |
|
||||
| Virtual scroll for table | Performance requirement for large finding sets |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| API latency for gated buckets | Cache bucket summary, refresh on lane toggle |
|
||||
| Complex breadcrumb state | Use route params for deep-linking support |
|
||||
| Bundle export timeout | Async job with polling, show progress |
