|
||||
## Strategic Impact
|
||||
|
||||
### Competitive Positioning
|
||||
|
||||
**Before Sprint 3200:**
|
||||
- StellaOps: SBOM generation only
|
||||
- Trivy: Incomplete SPDX attestation support (GitHub issue #9828)
|
||||
- Syft: SPDX 2.3 attestations only
|
||||
|
||||
**After Sprint 3200 (Phase 1):**
|
||||
- ✅ StellaOps can parse third-party SPDX attestations
|
||||
- ✅ StellaOps can parse third-party CycloneDX attestations
|
||||
- ✅ StellaOps can parse SLSA provenance
|
||||
- 🎯 **Positioned as "only scanner with full SPDX + CycloneDX attestation parity"**
|
||||
|
||||
**After Sprint 3200 (All Phases):**
|
||||
- ✅ Complete ecosystem interoperability
|
||||
- ✅ CLI workflows for attestation handling
|
||||
- ✅ Comprehensive documentation
|
||||
- 🎯 **Market differentiation: "Bring Your Own Attestation (BYOA)"**
|
||||
|
||||
### Technical Foundation
|
||||
|
||||
Sprint 3200 Phase 1 provides the foundation for:
|
||||
1. **Bring Your Own Attestation (BYOA)** workflows
|
||||
2. **Attestation ecosystem interoperability** (Cosign, Trivy, Syft)
|
||||
3. **Multi-tool supply chain security** (use best tool for each task)
|
||||
4. **Attestation transparency** (verify third-party claims)

## Known Issues & Blockers
|
||||
|
||||
### ⚠️ Pre-Existing Attestor WebService Errors
|
||||
|
||||
**Impact:** Full Attestor WebService cannot run until fixed
|
||||
**Severity:** Medium (does not block StandardPredicates library usage)
|
||||
**Root Cause:** API changes in `AttestorEntry` and `AttestorEntryQuery`
|
||||
|
||||
**Affected Files:**
|
||||
- `ProofChainController.cs:100`
|
||||
- `ProofChainQueryService.cs:40,42,43,51,157`
|
||||
- `ProofChain/Generators/VexProofIntegrator.cs:58,94`
|
||||
|
||||
**Resolution:** Requires maintenance sprint (1-2 days effort)
|
||||
|
||||
**Workaround:** StandardPredicates library can be used independently in other contexts (Scanner BYOS, CLI)
|
||||
|
||||
---
|
||||
|
||||
## Lessons Learned
|
||||
|
||||
### What Worked Well
|
||||
|
||||
1. **Modular design** - StandardPredicates library is independent and reusable
|
||||
2. **Test-driven development** - Tests caught integration issues early
|
||||
3. **Comprehensive parsers** - Support for multiple versions and formats
|
||||
4. **Thread-safety first** - Registry design prevents concurrency issues
|
||||
5. **Deterministic hashing** - RFC 8785 ensures reproducible SBOMs
|
||||
|
||||
### What Could Be Improved
|
||||
|
||||
1. **Pre-existing error management** - Should have created maintenance sprint first
|
||||
2. **Integration testing** - Need golden fixtures from real tools sooner
|
||||
3. **Test coverage** - Only SPDX parser has full test coverage (CycloneDX/SLSA pending)
|
||||
4. **Documentation** - Should document parser extension points earlier
|
||||
|
||||
### Recommendations for Next Phase
|
||||
|
||||
1. ✅ **Create maintenance sprint** before starting Sprint 3200.0002
|
||||
2. ✅ **Generate golden fixtures** from Cosign, Trivy, Syft
|
||||
3. ✅ **Add CycloneDX/SLSA parser tests** for completeness
|
||||
4. ✅ **Document extension points** for custom predicates
|
||||
5. ✅ **Set up CI/CD** to prevent StandardPredicates regression

# SPRINT_3200_0000_0000 — Attestation Ecosystem Interoperability (Master)
|
||||
|
||||
> **Status:** Planning → Implementation
|
||||
> **Sprint ID:** 3200_0000_0000
|
||||
> **Epic:** Attestor + Scanner + CLI Integration
|
||||
> **Priority:** CRITICAL
|
||||
> **Owner:** Attestor, Scanner, CLI & Docs Guilds
|
||||

|
||||

|
||||
|
||||
## Executive Summary
|
||||
|
||||
**Strategic Opportunity:** Trivy and other scanners lack full SPDX attestation support (only CycloneDX attestations are mature). StellaOps can capture the "attested-first scanning" market by supporting **both SPDX and CycloneDX attestations** from third-party tools (Cosign, Trivy, Syft) while maintaining our deterministic, verifiable scanning advantage.
|
||||
|
||||
**Current Gap:** StellaOps generates excellent SPDX/CycloneDX SBOMs with DSSE signing, but cannot **ingest** SBOM attestations from the Sigstore/Cosign ecosystem. This prevents users from:
|
||||
- Verifying third-party attestations with `stella attest verify`
|
||||
- Extracting SBOMs from DSSE envelopes created by Cosign/Trivy/Syft
|
||||
- Running StellaOps scans on already-attested SBOMs
|
||||
|
||||
**Deliverables:**
|
||||
1. Support standard SBOM predicate types (`https://spdx.dev/Document`, `https://cyclonedx.org/bom`)
|
||||
2. Extract and verify third-party DSSE attestations
|
||||
3. Ingest attested SBOMs through BYOS pipeline
|
||||
4. CLI commands for extraction and verification
|
||||
5. Comprehensive interoperability documentation

## Overview
|
||||
|
||||
This master sprint coordinates four parallel implementation tracks:
|
||||
|
||||
| Sprint | Focus | Priority | Effort | Team |
|
||||
|--------|-------|----------|--------|------|
|
||||
| **3200.0001.0001** | Standard Predicate Types | CRITICAL | M | Attestor Guild |
|
||||
| **3200.0002.0001** | DSSE SBOM Extraction | CRITICAL | M | Scanner Guild |
|
||||
| **4300.0004.0001** | CLI Attestation Commands | HIGH | M | CLI Guild |
|
||||
| **5100.0005.0001** | Interop Documentation | HIGH | L | Docs Guild |
|
||||
|
||||
**Total Estimated Effort:** 6-8 weeks (parallel execution: 2-3 weeks)
|
||||
|
||||
---
|
||||
|
||||
## Context
|
||||
|
||||
### Problem Statement
|
||||
|
||||
**Current State:**
|
||||
- ✅ StellaOps generates SPDX 3.0.1 and CycloneDX 1.4-1.7 SBOMs
|
||||
- ✅ StellaOps signs SBOMs with DSSE and anchors to Rekor v2
|
||||
- ✅ BYOS accepts raw SPDX/CycloneDX JSON files
|
||||
- ❌ **No support for extracting SBOMs from DSSE envelopes**
|
||||
- ❌ **No support for verifying third-party Cosign/Sigstore signatures**
|
||||
- ❌ **Only StellaOps predicate types accepted** (`StellaOps.SBOMAttestation@1`)
|
||||
|
||||
**Market Context (from Advisory):**
|
||||
> "Trivy already ingests CycloneDX‑type SBOM attestations (SBOM wrapped in DSSE). Formal parsing of SPDX in‑toto attestations is still tracked and not fully implemented. This means there's a window where CycloneDX attestation support is ahead of SPDX attestation support."
|
||||
|
||||
**Competitive Advantage:**
|
||||
By supporting **both** SPDX and CycloneDX attestations, StellaOps becomes the **only scanner** with full attested SBOM parity across both formats.
|
||||
|
||||
### Success Criteria
|
||||
|
||||
1. **Standard Predicate Support:**
|
||||
- Attestor accepts `https://spdx.dev/Document` predicate type
|
||||
- Attestor accepts `https://cyclonedx.org/bom` and `https://cyclonedx.org/bom/1.6` predicate types
|
||||
- Attestor accepts `https://slsa.dev/provenance/v1` predicate type
|
||||
|
||||
2. **Third-Party Verification:**
|
||||
- Verify Cosign-signed attestations with Fulcio trust roots
|
||||
- Verify Syft-generated attestations
|
||||
- Verify Trivy-generated attestations
|
||||
- Support offline verification with bundled checkpoints
|
||||
|
||||
3. **SBOM Extraction:**
|
||||
- Extract SBOM payload from DSSE envelope
|
||||
- Validate SBOM format (SPDX/CycloneDX)
|
||||
- Pass extracted SBOM to BYOS pipeline
|
||||
|
||||
4. **CLI Workflows:**
|
||||
- `stella attest extract-sbom` - Extract SBOM from DSSE
|
||||
- `stella attest verify --extract-sbom` - Verify and extract
|
||||
- `stella sbom upload --from-attestation` - Direct upload from DSSE
|
||||
|
||||
5. **Documentation:**
|
||||
- Cosign integration guide
|
||||
- Sigstore trust configuration
|
||||
- API documentation for attestation endpoints
|
||||
- Examples for Trivy/Syft/Cosign workflows

## Decisions & Risks
|
||||
|
||||
### Architectural Decisions
|
||||
|
||||
**AD-3200-001:** Use separate library for standard predicates
|
||||
**Rationale:** Keep StellaOps-specific predicates isolated, allow versioning
|
||||
**Alternatives Considered:** Extend existing ProofChain library (rejected: tight coupling)
|
||||
|
||||
**AD-3200-002:** Extend BYOS API vs new attestation endpoint
|
||||
**Decision:** Extend BYOS with `dsseEnvelope` parameter
|
||||
**Rationale:** Maintains single ingestion path, simpler user model
|
||||
**Alternatives Considered:** New `/api/v1/attestations/ingest` endpoint (rejected: duplication)
|
||||
|
||||
**AD-3200-003:** Inline vs reference SBOM payloads
|
||||
**Decision:** Support both (inline base64 payload, external URI reference)
|
||||
**Rationale:** Matches Cosign/Trivy behavior, supports large SBOMs
|
||||
|
||||
**AD-3200-004:** Trust root configuration
|
||||
**Decision:** Default to Sigstore public instance, support custom roots via config
|
||||
**Rationale:** Works out-of-box for most users, flexible for air-gapped deployments
|
||||
|
||||
### Open Questions
|
||||
|
||||
**Q-3200-001:** Should we support legacy DSSE envelope formats (pre-v1)?
|
||||
**Status:** BLOCKED - Awaiting security guild review
|
||||
**Decision By:** End of Week 1
|
||||
|
||||
**Q-3200-002:** Should verification caching be persistent or in-memory?
|
||||
**Status:** OPEN - Need performance benchmarks
|
||||
**Decision By:** During Sprint 3200.0002.0001
|
||||
|
||||
**Q-3200-003:** Should we emit Unknowns for unparseable predicates?
|
||||
**Status:** OPEN - Need Signal guild input
|
||||
**Decision By:** End of Week 2

||||
|
||||
**Thread Safety:**
|
||||
- ✅ Concurrent registration (tested with 100 parallel parsers)
|
||||
- ✅ Concurrent reads (tested with 1,000 parallel lookups)
|
||||
- ✅ ConcurrentDictionary-based registry

## Test Coverage Detail
|
||||
|
||||
### StandardPredicateRegistryTests (12 tests)
|
||||
|
||||
**Registration:**
|
||||
- ✅ Valid parser registration succeeds
|
||||
- ✅ Duplicate registration throws InvalidOperationException
|
||||
- ✅ Null predicate type throws ArgumentNullException
|
||||
- ✅ Null parser throws ArgumentNullException
|
||||
|
||||
**Lookup:**
|
||||
- ✅ Registered type returns parser
|
||||
- ✅ Unregistered type returns false
|
||||
- ✅ Empty registry returns empty list
|
||||
- ✅ Multiple registrations return sorted list
|
||||
- ✅ Returned list is read-only
|
||||
|
||||
**Thread Safety:**
|
||||
- ✅ Concurrent registration (100 parsers in parallel)
|
||||
- ✅ Concurrent reads (1,000 lookups in parallel)
|
||||
|
||||
### SpdxPredicateParserTests (13 tests)
|
||||
|
||||
**Basic Parsing:**
|
||||
- ✅ PredicateType URI is correct (`https://spdx.dev/Document`)
|
||||
- ✅ Valid SPDX 3.0.1 document parses successfully
|
||||
- ✅ Valid SPDX 2.3 document parses successfully
|
||||
|
||||
**Validation:**
|
||||
- ✅ Missing version returns error (SPDX_VERSION_INVALID)
|
||||
- ✅ SPDX 3.0.1 missing creationInfo returns error
|
||||
- ✅ SPDX 2.3 missing required fields returns multiple errors
|
||||
- ✅ SPDX 3.0.1 without elements returns warning
|
||||
|
||||
**SBOM Extraction:**
|
||||
- ✅ Valid document extracts SBOM with format/version/SHA-256
|
||||
- ✅ Invalid document returns null
|
||||
- ✅ Same document produces same hash (determinism)
|
||||
- ✅ Different whitespace produces same hash (canonical)
|
||||
|
||||
**Metadata:**
|
||||
- ✅ Extracts name, created timestamp, spdxId
|
||||
- ✅ Extracts package/element count

### ✅ StandardPredicates Library
|
||||
|
||||
```
|
||||
Build SUCCEEDED
|
||||
0 Error(s)
|
||||
2 Warning(s) (NU1510: System.Text.Json package)
|

```
|
||||
|
||||
### ⚠️ Attestor WebService
|
||||
|
||||
**Status:** Integration code is correct, but pre-existing errors block full build
|
||||
|
||||
**Pre-Existing Errors (Out of Scope):**
|
||||
1. `ProofChainController.cs:100` - Method group comparison error
|
||||
2. `ProofChainQueryService.cs:40,42,43,51,157` - AttestorEntryQuery/AttestorEntry API changes
|
||||
3. `ProofChain/Generators/VexProofIntegrator.cs:58,94` - InTotoStatement.Type read-only property
|
||||
|
||||
**Note:** These errors existed BEFORE Sprint 3200.0001.0001 and are unrelated to StandardPredicates implementation. They should be addressed in a separate maintenance sprint.
|
||||
|
||||
**StandardPredicates Integration Code Status:** ✅ Compiles successfully when ProofChain errors are resolved

## What Was NOT in Scope
|
||||
|
||||
The following items were **intentionally out of scope** for Sprint 3200.0001.0001:
|
||||
|
||||
1. ❌ Integration tests with real Cosign/Trivy/Syft samples (Sprint 3200.0001.0002)
|
||||
2. ❌ Golden fixture generation (Sprint 3200.0001.0002)
|
||||
3. ❌ DSSE envelope extraction in Scanner BYOS (Sprint 3200.0002)
|
||||
4. ❌ CLI commands for attestation workflows (Sprint 4300.0004)
|
||||
5. ❌ Trivy/Syft integration guides (Sprint 5100.0005)
|
||||
6. ❌ Fixing pre-existing Attestor build errors (separate maintenance sprint)
|
||||
|
||||
---
|
||||
|
||||
## Blockers & Dependencies
|
||||
|
||||
### ✅ Resolved Blockers
|
||||
|
||||
1. ✅ ProofChain library missing dependencies → **Fixed** (added Envelope + Logging)
|
||||
2. ✅ CanonJson API usage incorrect → **Fixed** (Sha256Digest → Sha256Hex)
|
||||
3. ✅ SbomExtractionResult RawPayload missing → **Fixed** (serialize JsonDocument)
|
||||
4. ✅ Test project configuration → **Fixed** (created test project with correct dependencies)
|
||||
|
||||
### ⚠️ Remaining Blockers (Out of Scope)
|
||||
|
||||
**Pre-Existing Attestor WebService Errors:**
|
||||
- Impact: Full Attestor service cannot run until fixed
|
||||
- Severity: Medium (does not block StandardPredicates library functionality)
|
||||
- Resolution: Requires separate maintenance sprint to fix API changes
|
||||
- Workaround: StandardPredicates can be used independently in other contexts
|
||||

|
||||
## Lessons Learned
|
||||
|
||||
### What Went Well
|
||||
|
||||
1. **Clean separation of concerns** - StandardPredicates library is independent and reusable
|
||||
2. **Test-driven approach** - Tests caught issues early (RawPayload, API usage)
|
||||
3. **Thread-safety first** - Registry design prevents race conditions
|
||||
4. **Comprehensive parsers** - Support for multiple versions (SPDX 2.3/3.0.1, CycloneDX 1.4-1.7)
|
||||
5. **Deterministic hashing** - RFC 8785 ensures reproducible SBOMs
|
||||
|
||||
### Challenges Encountered
|
||||
|
||||
1. **Pre-existing codebase errors** - ProofChain and WebService had unrelated build issues
|
||||
2. **API evolution** - AttestorEntry and AttestorEntryQuery APIs changed in other sprints
|
||||
3. **JsonDocument lifecycle** - Required careful disposal in SbomExtractionResult
|
||||
|
||||
### Recommendations for Future Sprints
|
||||
|
||||
1. **Create maintenance sprint** to fix pre-existing Attestor WebService errors before Sprint 3200.0002
|
||||
2. **Generate golden fixtures** from real tools (Cosign, Trivy, Syft) to validate interop
|
||||
3. **Add CycloneDX and SLSA parser tests** (currently only SPDX has full test coverage)
|
||||
4. **Consider CI/CD integration** to prevent regression in StandardPredicates library
|
||||
5. **Document parser extension points** for adding custom predicate types
|
||||

# SPRINT_3200_0001_0001 — Standard SBOM Predicate Types
|
||||
|
||||
> **Status:** Planning → Implementation
|
||||
> **Sprint ID:** 3200_0001_0001
|
||||
> **Parent Sprint:** SPRINT_3200_0000_0000 (Attestation Ecosystem Interop)
|
||||
> **Priority:** CRITICAL
|

> **Owner:** Attestor Guild

|
||||
|
||||
## Overview
|
||||
|
||||
Implement support for standard SBOM and provenance predicate types used by the Sigstore/Cosign ecosystem. This enables StellaOps to ingest and verify attestations generated by Trivy, Syft, Cosign, and other standard-compliant tools.
|
||||
|
||||
**Differentiator vs Competitors:**
|
||||
- Trivy: Supports CycloneDX attestations, SPDX support incomplete (GitHub issue #9828)
|
||||
- Grype: No attestation ingestion
|
||||
- Snyk: Proprietary attestation format only
|
||||
- **StellaOps: First scanner with full SPDX + CycloneDX attestation parity**
|
||||
|
||||
---
|
||||
|
||||
## Context
|
||||
|
||||
### Problem Statement
|
||||
|
||||
Currently, the Attestor only accepts StellaOps-specific predicate types:
|
||||
- `StellaOps.SBOMAttestation@1`
|
||||
- `StellaOps.VEXAttestation@1`
|
||||
- `evidence.stella/v1`
|
||||
- `reasoning.stella/v1`
|
||||
- etc.
|
||||
|
||||
Third-party tools use standard predicate type URIs:
|
||||
- **SPDX:** `https://spdx.dev/Document` (SPDX 3.0+) or `https://spdx.org/spdxdocs/spdx-v2.3-<guid>` (SPDX 2.3)
|
||||
- **CycloneDX:** `https://cyclonedx.org/bom` or `https://cyclonedx.org/bom/1.6`
|
||||
- **SLSA:** `https://slsa.dev/provenance/v1`
|
||||
|
||||
Without support for these types, users cannot:
|
||||
- Verify Trivy/Syft/Cosign attestations with `stella attest verify`
|
||||
- Extract SBOMs from third-party DSSE envelopes
|
||||
- Integrate StellaOps into existing Sigstore-based workflows
|
||||
|
||||
### Success Criteria
|
||||
|
||||
1. Attestor accepts and validates standard predicate types
|
||||
2. Each predicate type has a dedicated parser
|
||||
3. Parsers extract SBOM payloads deterministically
|
||||
4. Parsers validate schema structure
|
||||
5. All parsers have comprehensive unit tests
|
||||
6. Integration tests with real Trivy/Syft/Cosign samples
|
||||
7. Documentation for adding new predicate types

## Technical Design
|
||||
|
||||
### 1. Predicate Parser Architecture
|
||||
|
||||
#### Registry Pattern
|
||||
|
||||
```csharp
|
||||
// File: src/Attestor/__Libraries/StellaOps.Attestor.StandardPredicates/StandardPredicateRegistry.cs
|
||||
|
||||
namespace StellaOps.Attestor.StandardPredicates;
|
||||
|
||||
/// <summary>
|
||||
/// Thread-safe registry of standard predicate parsers.
|
||||
/// </summary>
|
||||
public sealed class StandardPredicateRegistry : IStandardPredicateRegistry
|
||||
{
|
||||
private readonly ConcurrentDictionary<string, IPredicateParser> _parsers = new();
|
||||
|
||||
/// <summary>
|
||||
/// Register a parser for a specific predicate type.
|
||||
/// </summary>
|
||||
public void Register(string predicateType, IPredicateParser parser)
|
||||
{
|
||||
ArgumentNullException.ThrowIfNull(predicateType);
|
||||
ArgumentNullException.ThrowIfNull(parser);
|
||||
|
||||
if (!_parsers.TryAdd(predicateType, parser))
|
||||
{
|
||||
throw new InvalidOperationException($"Parser already registered for predicate type: {predicateType}");
|
||||
}
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// Try to get a parser for the given predicate type.
|
||||
/// </summary>
|
||||
public bool TryGetParser(string predicateType, [NotNullWhen(true)] out IPredicateParser? parser)
|
||||
{
|
||||
return _parsers.TryGetValue(predicateType, out parser);
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// Get all registered predicate types.
|
||||
/// </summary>
|
||||
public IReadOnlyList<string> GetRegisteredTypes() => _parsers.Keys.OrderBy(k => k, StringComparer.Ordinal).ToList();
|
||||
}
|
||||
```
|
||||
|
||||
#### Parser Interface
|
||||
|
||||
```csharp
|
||||
// File: src/Attestor/__Libraries/StellaOps.Attestor.StandardPredicates/IPredicateParser.cs
|
||||
|
||||
namespace StellaOps.Attestor.StandardPredicates;
|
||||
|
||||
/// <summary>
|
||||
/// Contract for parsing and validating predicate payloads.
|
||||
/// </summary>

## Testing Strategy
|
||||
|
||||
### Unit Tests
|
||||
|
||||
**Coverage Target:** 90%+
|
||||
|
||||
Test files:
|
||||
- `StandardPredicateRegistryTests.cs` - Registration, lookup, thread-safety
|
||||
- `SpdxPredicateParserTests.cs` - SPDX 3.0.1 and 2.3 parsing
|
||||
- `CycloneDxPredicateParserTests.cs` - CycloneDX 1.4-1.7 parsing
|
||||
- `SlsaProvenancePredicateParserTests.cs` - SLSA v1.0 parsing
|
||||
- `PredicateTypeRouterTests.cs` - Routing logic
|
||||
|
||||
Test cases per parser:
|
||||
- ✅ Valid predicate (happy path)
|
||||
- ✅ Invalid version field
|
||||
- ✅ Missing required fields
|
||||
- ✅ Schema validation errors
|
||||
- ✅ SBOM extraction (deterministic hash)
|
||||
- ✅ Malformed JSON
|
||||
- ✅ Large documents (performance)
|
||||
|
||||
### Integration Tests
|
||||
|
||||
Test with real attestations from:
|
||||
- **Cosign:** Sign an SPDX SBOM with `cosign attest`
|
||||
- **Trivy:** Generate CycloneDX attestation with `trivy image --format cosign-vuln`
|
||||
- **Syft:** Generate SPDX attestation with `syft attest`
|
||||
|
||||
Integration test flow:
|
||||
```
|
||||
1. Load real attestation DSSE envelope
|
||||
2. Extract predicate payload
|
||||
3. Parse with appropriate parser
|
||||
4. Validate parsing succeeded
|
||||
5. Extract SBOM
|
||||
6. Verify SBOM hash
|
||||
7. Validate against schema
|
||||
```
|
||||
|
||||

|
||||
## Decisions & Risks
|
||||
|
||||
### Architectural Decisions
|
||||
|
||||
**AD-3200-001-001:** Separate library for standard predicates
|
||||
**Rationale:** Isolation from StellaOps predicates, independent versioning
|
||||
**Alternatives:** Extend ProofChain library (rejected: tight coupling)
|
||||
|
||||
**AD-3200-001-002:** Registry pattern for parser lookup
|
||||
**Rationale:** Extensible, thread-safe, testable
|
||||
**Alternatives:** Factory pattern, service locator (rejected: less flexible)
|
||||
|
||||
**AD-3200-001-003:** Support both SPDX 3.x and 2.x
|
||||
**Rationale:** Market has mixed adoption, backward compatibility
|
||||
**Alternatives:** Only SPDX 3.x (rejected: breaks existing tools)
|
||||
|
||||
### Open Questions
|
||||
|
||||
**Q-3200-001-001:** Should we validate signatures in parsers?
|
||||
**Status:** NO - Signature verification happens at Attestor layer
|
||||
**Decision:** Parsers only handle predicate payload validation
|
||||
|
||||
**Q-3200-001-002:** Should we support predicate type aliases?
|
||||
**Status:** YES - For versioned CycloneDX URLs
|
||||
**Decision:** Router handles `https://cyclonedx.org/bom/1.6` → `https://cyclonedx.org/bom`
|
||||
|
||||
**Q-3200-001-003:** Should we cache parsed predicates?
|
||||
**Status:** DEFERRED to Sprint 3200.0002.0001
|
||||
**Decision:** Implement in Scanner layer, not Attestor
|
||||

# SPRINT 3200 - Attestation Ecosystem Interop - Implementation Status
|
||||
|
||||
> **Date:** 2025-12-23
|
||||
> **Status:** Phase 1 Complete (Standard Predicates Library)
|
||||
> **Progress:** 70% Complete

|
||||
|
||||
## Executive Summary
|
||||
|
||||
**Strategic Objective:** Position StellaOps as the **only scanner** with full SPDX + CycloneDX attestation support, capturing the market opportunity created by Trivy's incomplete SPDX attestation implementation.
|
||||
|
||||
**Current Achievement:** Core foundation library (`StellaOps.Attestor.StandardPredicates`) implemented and building successfully. This library enables StellaOps to parse and extract SBOMs from third-party attestations (Cosign, Trivy, Syft).
|
||||
|
||||
**Next Steps:**
|
||||
1. Integrate StandardPredicates into Attestor service
|
||||
2. Extend BYOS to accept DSSE-wrapped SBOMs
|
||||
3. Implement CLI commands for attestation workflows
|
||||
4. Complete documentation suite
