|

## Original Advisory
|
||||
|
||||
Here's a practical, low-BS playbook for **proving build time** in CI/CD and for long-term auditability, with clear choices depending on cost/latency vs legal weight.
|
||||
|
||||
### CI/CD-grade timestamps (default)
|
||||
|
||||
* **Use RFC-3161 Time-Stamp Tokens (TSTs).** A TST is a signed blob (CMS/ASN.1) from a Time-Stamp Authority (TSA) attesting "hash X existed at time T."
|
||||
* **When:** every build step that emits a signed artifact (attestations, SBOMs, release bundles, provenance).
|
||||
* **How:**
|
||||
|
||||
1. Hash your artifact (SHA-256).
|
||||
2. Send the hash to a TSA via RFC-3161.
|
||||
3. Persist: the **raw TST**, **TSA cert chain**, **OCSP/CRL responses**, and your **request hash**.
|
||||
4. **Re-timestamp periodically** (e.g., yearly or before TSA cert expiry/algorithm deprecation) to keep the proof alive even if keys are rotated or revoked.
|
||||
* **Why:** low latency (<~100–300 ms typical), low cost, standard, and defensible for engineering/compliance audits.
|
||||
|
||||
### Legal-grade timestamps (when you need EU courtroom weight)
|
||||
|
||||
* **Use eIDAS Qualified Time-Stamps (QTS).**
|
||||
* **When:** contracts, tender submissions, regulated filings, high-stakes disputes.
|
||||
* **Trade-offs:** higher cost, KYC/contract with provider, higher latency—but strong legal presumption of accuracy in the EU.
|
||||
|
||||
### Don't rely on Rekor time alone
|
||||
|
||||
* **Always anchor artifacts in a transparency log (e.g., Rekor)** for tamper-evidence and inclusion proofs.
|
||||
* **But:** **do not** treat Rekor's `integratedTime` as your sole wall-clock proof; it's not part of the signed node. Combine **Rekor inclusion proof + (TST or QTS)** and keep both.
|
||||
|
||||
### What to store per artifact
|
||||
|
||||
* Artifact digest(s) + media type
|
||||
* **TST/QTS** (raw CMS blob)
|
||||
* **TSA chain** (certs) + **OCSP/CRL** at issuance time
|
||||
* **Rekor entry** (UUID), inclusion proof, tree ID, SignedEntryTimestamp
|
||||
* Verification metadata (tool versions, policy version)
|
||||
* Retention plan: **re-timestamp schedule** + algorithm migration policy (e.g., SHA-256→SHA-512, PQC later)
|
||||
|
||||
### Verification pipeline (offline-capable)
|
||||
|
||||
1. Recompute artifact hash.
|
||||
2. Verify CMS signature on TST/QTS and validate TSA chain against stored trust roots.
|
||||
3. Check OCSP/CRL (at-issuance stapled responses; optionally perform fresh status).
|
||||
4. Validate Rekor inclusion proof (Merkle path against stored tree head).
|
||||
5. Cross-check: TST time ≤ Rekor integrated inclusion window ≤ release tag time (policy-enforced skew).
|
||||
|
||||
### Where this fits in **Stella Ops**
|
||||
|
||||
* **Scanner/SBOM/VEX emitters:** attach RFC-3161 TST to every attestation (DSSE/CycloneDX/SPDX).
|
||||
* **Release Orchestrator:** block promotion unless (a) TST verifies, (b) Rekor inclusion proof verifies, (c) time-skew within policy.
|
||||
* **Authority service:** manages **TSA providers**, **trust anchors**, OCSP/CRL caching, and **re-timestamp jobs**.
|
||||
* **Evidence store:** immutable blobs for TST/QTS, OCSP/CRL, Rekor proofs; index by artifact digest and build run.
|
||||
* **Doctor checks:** warn on near-expiry TSA roots, missing stapled OCSP, or stale algorithms.
|
||||
* **Air-gap profile:** bundle TSA chain + last-known OCSP/CRL; queue re-timestamp when reconnected.
|
||||
|
||||
### Example CLI flow (concept)
|
||||
|
||||
```bash
|
||||
# 1) Create provenance and attach TST
|
||||
stella sbom emit --image ghcr.io/acme/app:1.4.2 --out sbom.cdx.json
|
||||
stella attest sign --in sbom.cdx.json --out sbom.dsse
|
||||
stella ts rfc3161 --hash $(sha256sum sbom.dsse | cut -d' ' -f1) \
|
||||
--tsa https://tsa.example.com --out sbom.dsse.tst
|
||||
|
||||
# 2) Rekor anchor
|
||||
stella rekor upload --artifact sbom.dsse --bundle sbom.rekor.bundle
|
||||
|
||||
# 3) Persist evidence
|
||||
stella evidence store --artifact sbom.dsse \
|
||||
--tst sbom.dsse.tst --rekor-bundle sbom.rekor.bundle \
|
||||
--tsa-chain tsa_chain.pem --ocsp ocsp.der --crl crl.der
|
||||
|
||||
# 4) Gate before promote
|
||||
stella gate verify --artifact sbom.dsse --policy gates/ts_integrity.yaml
|
||||
```
|
||||
|
||||
### Minimal policy (starter)
|
||||
|
||||
```yaml
|
||||
rules:
|
||||
- id: require-rfc3161
|
||||
assert: evidence.tst.valid == true
|
||||
- id: require-rekor
|
||||
assert: evidence.rekor.inclusion_proof_valid == true
|
||||
- id: time-skew
|
||||
assert: abs(evidence.tst.time - evidence.release.tag_time) <= "5m"
|
||||
- id: freshness
|
||||
assert: evidence.tst.signing_cert.expires_at - now() > "180d"
|
||||
- id: revocation-staple
|
||||
assert: evidence.tst.ocsp.status in ["good","unknown"] && evidence.tst.crl.checked == true
|
||||
```
|
||||
|
||||
### Provider strategy
|
||||
|
||||
* **Default:** fast, inexpensive RFC-3161 TSA for all builds.
|
||||
* **Override per environment/repo:** eIDAS **QTS** for regulated projects.
|
||||
* Keep **2+ TSAs** configured for failover; log which one issued each TST.
|
||||
|
||||
### Long-term resilience
|
||||
|
||||
* Schedule **re-timestamping** before TSA cert/key expiry or after algorithm deprecation.
|
||||
* Keep detached evidence so proofs remain verifiable **offline** for years.
|
||||
* Plan an optional **post-quantum** mode later (e.g., Dilithium-backed TSA/QTES once practical).

## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
- **D1:** Follow Concelier/Excititor three-phase pattern (Fetch → Parse → Map) for consistency
|
||||
- **D2:** Apply AOC invariants: immutable observations, mandatory provenance, deterministic output
|
||||
- **D3:** Support offline mode via cached raw documents and pre-computed observations
|
||||
- **D4:** LibObjectFile 1.0.0 API migration deferred - ELF/DWARF parsers stubbed to unblock builds
|
||||
|
||||
### Risks
|
||||
- **R1:** External service availability (debuginfod, ddebs repos) - Mitigated by caching and offline fixtures
|
||||
- **R2:** DWARF parsing complexity across compiler versions - Mitigated by using established libraries (Gimli/libdw)
|
||||
- **R3:** Schema evolution for symbol observations - Mitigated by versioned schemas and supersession model
|
||||
- **R4:** ELF/DWARF parsing stubbed due to LibObjectFile 1.0.0 breaking changes - Requires follow-up sprint for API migration
|
||||
|
||||

||||
- Ground-truth architecture: `docs/modules/binary-index/ground-truth-corpus.md`

## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
- **D1:** Use security pairs from ground-truth corpus as oracle (symbol-based truth)
|
||||
- **D2:** Track mismatch causes to guide normalizer/fingerprint improvements
|
||||
- **D3:** Generate DSSE attestations for all validation runs for auditability
|
||||
|
||||
### Risks
|
||||
- **R1:** Mismatch cause detection heuristics may misclassify - Mitigated by manual review of samples
|
||||
- **R2:** Validation runs may be slow for large corpora - Mitigated by parallel execution and caching
|
||||
- **R3:** Dependency on ground-truth corpus sprint - Mitigated by stub oracle for early development

|
||||
| Date (UTC) | Update | Owner |

|
||||
| 2026-01-19 | Sprint created for binary analysis doctor checks per advisory | Planning |

|
||||
## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
- **D1:** Place under "Security" category alongside attestation checks
|
||||
- **D2:** Fallback check allows any single source to satisfy requirement
|
||||
- **D3:** Provide distribution-specific remediation (Ubuntu vs Fedora vs Debian)
|
||||
|
||||
### Risks
|
||||
- **R1:** APT sources parsing may vary across Ubuntu versions - Mitigated by testing on LTS versions
|
||||
- **R2:** Network timeouts in air-gapped environments - Mitigated by quick timeout and clear messaging
|
||||
- **R3:** Check dependencies on connector config - Mitigated by sensible defaults
|
||||
|
||||
### Documentation Links
|
||||
- Doctor plugin guide: `docs/doctor/README.md`
|
||||
- Ground-truth connectors: `docs/modules/binary-index/ground-truth-corpus.md#4-connector-specifications`
|
||||
|
||||
## Next Checkpoints

# Sprint 20260119-004 · DeltaSig Predicate Schema Extensions
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
- Extend DeltaSig predicate schema to include symbol provenance and IR diff references.
|
||||
- Enable VEX explanations to cite concrete function-level evidence, not just CVE text.
|
||||
- Integrate with ground-truth corpus for symbol attribution.
|
||||
- Working directory: `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.DeltaSig`
|
||||
- Expected evidence: Extended schema definitions, predicate generation, VEX integration tests.
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- **Upstream:** Existing DeltaSig predicate (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.DeltaSig`)
|
||||
- **Upstream:** Ground-truth symbol observations (SPRINT_20260119_001)
|
||||
- **Parallel-safe:** Schema extension can proceed while corpus is populated
|
||||
- **Downstream:** VexLens will consume extended predicates for evidence surfacing
|
||||
|
||||
## Documentation Prerequisites
|
||||
|
||||
- `docs/modules/binary-index/architecture.md` - DeltaSig section
|
||||
- `docs/modules/binary-index/semantic-diffing.md` - IR diff algorithms
|
||||
- `docs/modules/binary-index/ground-truth-corpus.md` - Symbol provenance model

## Execution Log
|
||||
|
||||
| Date (UTC) | Update | Owner |
|
||||
| --- | --- | --- |
|
||||
| 2026-01-19 | Sprint created for DeltaSig schema extensions per advisory | Planning |
|
||||
| 2026-01-19 | DSIG-001: Created v2 models, converter, JSON schema. Fixed pre-existing build errors (duplicate types, method access issues). Library builds successfully. Tests pending due to pre-existing placeholder conflicts in test project | Developer |
|
||||
| 2026-01-19 | DSIG-002: Created ISymbolProvenanceResolver and GroundTruthProvenanceResolver. Added GroundTruth.Abstractions dependency. Fixed SecurityPairService pre-existing issue (GetByIdAsync -> FindByIdAsync) | Developer |
|
||||

|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
- **D1:** Introduce v2 predicate type, maintain v1 compatibility
|
||||
- **D2:** Store IR diffs in CAS, reference by digest in predicate
|
||||
- **D3:** Symbol provenance is optional (graceful degradation if corpus unavailable)
|
||||
|
||||
### Risks
|
||||
- **R1:** IR diff size may be large for complex functions - Mitigated by CAS storage and summary in predicate
|
||||
- **R2:** VexLens integration requires coordination - Mitigated by interface contracts
|
||||
- **R3:** v1 consumers may not understand v2 - Mitigated by version negotiation
|
||||
- **R4:** Pre-existing build errors in BinaryIndex.Semantic and DeltaSig projects blocking validation - Requires separate fix sprint
|
||||
|
||||
### Blocking Issues (requires resolution before continuing)
|
||||
1. `StellaOps.BinaryIndex.Semantic/Models/IrModels.cs`: CS0101 duplicate definition of `LiftedFunction` and `IrStatement`
|
||||
2. `StellaOps.BinaryIndex.DeltaSig/Attestation/DeltaSigAttestorIntegration.cs`: CS0176 PredicateType accessed incorrectly
|
||||
3. `StellaOps.BinaryIndex.DeltaSig/DeltaSigService.cs`: CS1061 missing `Compare` method on `IDeltaSignatureMatcher`
|
||||
|
||||

||||
## Topic & Scope
|
||||
|
||||
- Integrate with Debian reproducible builds infrastructure (reproduce.debian.net) for byte-identical binary reconstruction.

|
||||
## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
- **D1:** Support both remote (reproduce.debian.net) and local rebuild backends
|
||||
- **D2:** Local rebuilds use containerized build environments for isolation
|
||||
- **D3:** Defer to Phase 4 unless specific customer requires it (per advisory)
|
||||
|
||||
### Risks
|
||||
- **R1:** reproduce.debian.net availability/capacity - Mitigated by local backend fallback
|
||||
- **R2:** Build environment reproducibility varies by package - Mitigated by determinism validation
|
||||
- **R3:** Container setup complexity - Mitigated by pre-built base images

||||

- **D3:** ONNX export for .NET inference (avoid Python dependency in production)
|
||||
|
||||
### Risks
|
||||
- **R1:** Training data quality depends on ground-truth corpus - Mitigated by corpus validation
|
||||
- **R2:** Inference latency may impact scan time - Mitigated by caching and batching
|
||||
- **R3:** Model size may be large - Mitigated by quantization and ONNX optimization

|
||||
| 2026-01-19 | TSA-001: Created core abstractions in StellaOps.Authority.Timestamping.Abstractions (ITimeStampAuthorityClient, TimeStampRequest, TimeStampToken, TimeStampResponse, TimeStampVerificationResult, TsaClientOptions) | Developer |

|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
- **D1:** Use System.Formats.Asn1 for ASN.1 parsing (no external dependencies)
|
||||
- **D2:** Use System.Security.Cryptography.Pkcs for CMS/SignedData verification
|
||||
- **D3:** Support SHA-256/384/512 hash algorithms; SHA-1 deprecated but parseable for legacy TSTs
|
||||
- **D4:** Defer OCSP/CRL integration to Sprint 008 - use placeholder interface
|
||||
|
||||
### Risks
|
||||
- **R1:** TSA availability during CI builds - Mitigated by multi-provider failover and caching
|
||||
- **R2:** ASN.1 parsing complexity - Mitigated by comprehensive test fixtures from real TSAs
|
||||
- **R3:** Clock skew between build server and TSA - Mitigated by configurable tolerance (default 5m)
|
||||
|
||||
### Documentation Links
|
||||
- RFC 3161: https://datatracker.ietf.org/doc/html/rfc3161

||||
- RFC 5816: https://datatracker.ietf.org/doc/html/rfc5816

# Sprint 20260119-008 · Certificate Status Provider Infrastructure
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
- Implement unified certificate revocation checking infrastructure (OCSP and CRL).
|
||||
- Create shared `ICertificateStatusProvider` abstraction usable by TSA validation, Rekor key checking, TLS transport, and Fulcio certificates.
|
||||
- Support stapled OCSP responses for long-term validation and offline verification.
|
||||
- Working directory: `src/__Libraries/StellaOps.Cryptography.CertificateStatus`
|
||||
- Expected evidence: Unit tests, integration tests with mock OCSP/CRL endpoints, deterministic fixtures.
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- **Upstream:** Sprint 007 (TSA Client) - validates against TSA certificate chains
|
||||
- **Parallel-safe:** Can start after TSA-004 is complete
|
||||
- **Downstream:** Sprint 009 (Evidence Storage) depends on OCSP/CRL blob format
|
||||
- **Downstream:** Sprint 011 (eIDAS) depends on qualified revocation checking
|
||||
|
||||
## Documentation Prerequisites
|
||||
|
||||
- RFC 6960: Online Certificate Status Protocol (OCSP)
|
||||
- RFC 5280: Internet X.509 PKI Certificate and CRL Profile

## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
- **D1:** Place in shared `src/__Libraries/` for cross-module reuse
|
||||
- **D2:** OCSP preferred over CRL by default (lower latency, fresher data)
|
||||
- **D3:** Support both online and offline (stapled) verification modes
|
||||
- **D4:** Use in-memory caching with configurable size limits
|
||||
|
||||
### Risks
|
||||
- **R1:** OCSP responder availability - Mitigated by CRL fallback
|
||||
- **R2:** Large CRL download times - Mitigated by delta CRL support and caching
|
||||
- **R3:** Stapled response freshness - Mitigated by policy-based age limits
|
||||
|
||||

|
||||
## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
- **D1:** Store raw TST blob (DER) rather than parsed fields only - enables future re-parsing
|
||||
- **D2:** Store TSA chain as PEM for readability in bundles
|
||||
- **D3:** Supersession chain for re-timestamps rather than replacement
|
||||
- **D4:** Deterministic bundle structure for reproducibility
|
||||
|
||||
### Risks
|
||||
- **R1:** Large CRL snapshots - Mitigated by preferring OCSP, compressing in bundles
|
||||
- **R2:** Schema migration on large tables - Mitigated by async migration, no locks
|
||||
- **R3:** Bundle size growth - Mitigated by optional timestamp inclusion flag
|
||||
|
||||
### Documentation Links
|
||||
- Evidence bundle v1: `docs/modules/evidence-locker/evidence-bundle-v1.md`
|
||||
- Sealed mode: `docs/contracts/sealed-mode.md`
|
||||
|
||||
## Next Checkpoints

# Sprint 20260119-010 · Attestor TST Integration
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
- Integrate RFC-3161 timestamping into the attestation pipeline.
|
||||
- Automatically timestamp attestations (DSSE envelopes) after signing.
|
||||
- Extend verification to require valid TSTs alongside Rekor inclusion proofs.
|
||||
- Working directory: `src/Attestor/__Libraries/StellaOps.Attestor.Timestamping`
|
||||
- Expected evidence: Unit tests, integration tests, policy verification tests.
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- **Upstream:** Sprint 007 (TSA Client) - Provides `ITimestampingService`
|
||||
- **Upstream:** Sprint 008 (Certificate Status) - Provides `ICertificateStatusProvider`
|
||||
- **Upstream:** Sprint 009 (Evidence Storage) - Provides `ITimestampEvidenceRepository`
|
||||
- **Parallel-safe:** Can start after TSA-006, CSP-007, EVT-003 are complete
|
||||
- **Downstream:** Sprint 012 (Doctor) uses attestation timestamp health status
|
||||
|
||||
## Documentation Prerequisites
|
||||
|
||||
- `docs/modules/attestor/rekor-verification-design.md` - Existing Rekor verification
|
||||
- `docs/modules/attestor/architecture.md` - Attestor module design
|
||||
- RFC 3161 / RFC 5816 - TST format and verification

|
||||
Task description:
|
||||
Implement strict time correlation between TST and Rekor to prevent backdating attacks.
|
||||
|
||||
Attack scenario:
|
||||
- Attacker obtains valid TST for malicious artifact
|
||||
- Attacker waits and submits to Rekor much later
|
||||
- Without correlation, both look valid independently
|
||||
|
||||
Mitigation:
|
||||
- TST genTime must be ≤ Rekor integratedTime
|
||||
- Configurable maximum gap (default 5 minutes)
|
||||
- Alert on suspicious gaps (> 1 minute typical)
|
||||
|
||||
Implementation:
|
||||
```csharp
|
||||
public interface ITimeCorrelationValidator
|
||||
{
|
||||
TimeCorrelationResult Validate(
|
||||
DateTimeOffset tstTime,
|
||||
DateTimeOffset rekorTime,
|
||||
TimeCorrelationPolicy policy);

## Execution Log

| Date (UTC) | Update | Owner |
|
||||
| --- | --- | --- |
|
||||
| 2026-01-19 | Sprint created from RFC-3161/eIDAS timestamping advisory | Planning |
|
||||
| 2026-01-19 | ATT-001/ATT-002: Implemented via IAttestationTimestampService in Attestor.Timestamping lib | Dev |
|
||||
| 2026-01-19 | ATT-003: AttestationTimestampPolicyContext implemented for policy integration | Dev |

| 2026-01-20 | ATT-004: Implemented CycloneDxTimestampExtension, SpdxTimestampExtension, Rfc3161TimestampMetadata | Dev |
|

| 2026-01-20 | ATT-006: Implemented ITimeCorrelationValidator, TimeCorrelationValidator with policy and metrics | Dev |
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
- **D1:** Timestamp after signing but before Rekor submission
|
||||
- **D2:** Store TST reference in attestation metadata, not embedded in DSSE
|
||||
- **D3:** Time correlation is mandatory when both TST and Rekor are present
|
||||
- **D4:** CLI follows advisory example flow for familiarity
|
||||
|
||||
### Risks
|
||||
- **R1:** TSA latency impacts attestation throughput - Mitigated by async timestamping option
|
||||
- **R2:** Time correlation false positives during CI bursts - Mitigated by configurable tolerance
|
||||
- **R3:** Policy complexity - Mitigated by sensible defaults and clear documentation
|
||||
|
||||
### Documentation Links
|
||||
- Rekor verification: `docs/modules/attestor/rekor-verification-design.md`
|
||||
- Policy engine: `docs/modules/policy/policy-engine.md`
|
||||
|
||||
## Next Checkpoints

|
||||
- [ ] ATT-002 complete: Verification pipeline with TST validation
|

||||
- **D3:** Historical qualification check required (not just current status)
|
||||
- **D4:** Default to RFC-3161 unless explicitly configured for qualified
|
||||
|
||||
### Risks
|
||||
- **R1:** EU Trust List availability - Mitigated by caching and offline fallback
|
||||
- **R2:** QTS provider costs - Mitigated by selective use for regulated paths only
|
||||
- **R3:** CAdES complexity - Mitigated by phased implementation (T → LT → LTA)
|
||||
- **R4:** Historical status gaps in trust list - Mitigated by audit logging, fail-safe mode

## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
- **D1:** Separate plugin for timestamping checks (not merged with existing)
|
||||
- **D2:** Conservative auto-remediation (opt-in, rate-limited)
|
||||
- **D3:** Dashboard integration via existing Doctor UI framework
|
||||
- **D4:** Metrics exposed for Prometheus/Grafana integration
|
||||
|
||||
### Risks
|
||||
- **R1:** Check overhead on production systems - Mitigated by configurable intervals
|
||||
- **R2:** Auto-remediation side effects - Mitigated by rate limits and audit logging
|
||||
- **R3:** Alert fatigue - Mitigated by severity tuning and aggregation

|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
- **Decision**: Maintain backwards compatibility by keeping existing SbomDocument fields; new fields are additive
|
||||
- **Risk**: CycloneDX.Core NuGet package may not fully support 1.7 types yet; mitigation is using custom models
|
||||
- **Risk**: Large model expansion may impact memory for huge SBOMs; mitigation is lazy evaluation where possible
|
||||
- **Decision**: Signatures are serialized but NOT generated/verified by writer (signing is handled by Signer module)
|
||||
|
||||
## Next Checkpoints
|
||||
|
||||
- TASK-013-002 completion: Writer functional with 1.7 spec
|
||||
- TASK-013-009 completion: Full test coverage

## Decisions & Risks
|
||||
|
||||
- **Decision**: Support all 8 SPDX 3.0.1 profiles for completeness
|
||||
- **Decision**: Lite profile is opt-in via configuration, full profile is default
|
||||
- **Risk**: JSON-LD context loading may require network access; mitigation is bundling context file
|
||||
- **Risk**: AI/Dataset profiles are new and tooling support varies; mitigation is thorough testing
|
||||
- **Decision**: Use same SbomDocument model as CycloneDX where concepts overlap (components, relationships, vulnerabilities)
|
||||
|
||||
## Next Checkpoints
|
||||
|
||||
- TASK-014-003 completion: Software profile functional
|
||||
- TASK-014-004 completion: Security profile functional (VEX integration)
|
||||
- TASK-014-014 completion: Full test coverage

# Sprint 20260119_015 · Full SBOM Extraction for CycloneDX 1.7 and SPDX 3.0.1
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
- Upgrade SbomParser to extract ALL fields from CycloneDX 1.7 and SPDX 3.0.1 (not just PURL/CPE)
|
||||
- Create enriched internal model (ParsedSbom) that carries full SBOM data for downstream consumers
|
||||
- Enable Scanner, Policy, and other modules to access services, crypto, ML, build, and compliance metadata
|
||||
- Working directory: `src/Concelier/__Libraries/StellaOps.Concelier.SbomIntegration/`
|
||||
- Secondary: `src/__Libraries/StellaOps.Artifact.Core/`
|
||||
- Expected evidence: Unit tests, integration tests with downstream consumers
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- Depends on: SPRINT_20260119_013 (CycloneDX 1.7 model), SPRINT_20260119_014 (SPDX 3.0.1 model)
|
||||
- Blocks: All downstream scanner utilization sprints (016-023)
|
||||
- Can begin model work before generation sprints complete
|
||||
|
||||
## Documentation Prerequisites
|
||||
|
||||
- CycloneDX 1.7 spec: https://cyclonedx.org/docs/1.7/
|
||||
- SPDX 3.0.1 spec: https://spdx.github.io/spdx-spec/v3.0.1/

| Date (UTC) | Update | Owner |
|

| --- | --- | --- |
|

| 2026-01-19 | Sprint created for full SBOM extraction | Planning |
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
- **Decision**: Create new ParsedSbom model rather than extending existing to avoid breaking changes
|
||||
- **Decision**: Store full JSON in database with indexed query columns for performance
|
||||
- **Risk**: Large SBOMs with full extraction may impact memory; mitigation is streaming parser for huge files
|
||||
- **Risk**: SPDX 3.0.1 profile detection may be ambiguous; mitigation is explicit profile declaration check
|
||||
- **Decision**: Maintain backwards compatibility with existing minimal extraction API
|
||||

||||

|
||||
## Topic & Scope
|
||||
|
||||
- Enable Scanner to analyze services declared in CycloneDX 1.7 SBOMs
|
||||
- Detect security issues with service endpoints (authentication, trust boundaries, data flows)
|
||||
- Correlate service dependencies with known API vulnerabilities
|
||||
- Integrate with existing reachability analysis for service-to-service flows
|
||||
- Working directory: `src/Scanner/`
|
||||
- Secondary: `src/Concelier/__Libraries/StellaOps.Concelier.SbomIntegration/`
|
||||
- Expected evidence: Unit tests, integration tests, security rule coverage
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- Depends on: SPRINT_20260119_015 (Full SBOM extraction - ParsedService model)
|
||||
- Can run in parallel with other Scanner sprints after 015 delivers ParsedService
|
||||
|
||||
## Documentation Prerequisites
|
||||
|
||||
- CycloneDX services specification: https://cyclonedx.org/docs/1.7/#services

## Decisions & Risks
|
||||
|
||||
- **Decision**: Focus on CycloneDX services first; SPDX doesn't have equivalent concept
|
||||
- **Decision**: Use CWE mappings for standardized finding classification
|
||||
- **Risk**: Service names may not have CVE mappings; mitigation is CPE generation heuristics
|
||||
- **Risk**: Trust boundary information may be incomplete; mitigation is conservative analysis
|
||||
- **Decision**: Service analysis is opt-in initially to avoid breaking existing workflows

|
||||
- **Risk**: Algorithm strength classifications change over time; mitigation is configurable database
|
||||
- **Risk**: Certificate chain analysis requires external validation; mitigation is flag incomplete chains
|
||||
- **Decision**: Exemptions require expiration dates to prevent permanent exceptions
|
||||
|
||||
## Next Checkpoints

||||
|
||||
- TASK-017-003 completion: FIPS compliance functional

- **Risk**: Training data assessment may be incomplete; mitigation is flag unknown provenance
|
||||
- **Decision**: Research/sandbox models can have risk acceptance exemptions

## Execution Log
|
||||
|
||||
| Date (UTC) | Update | Owner |
|
||||
| --- | --- | --- |
|
||||
| 2026-01-19 | Sprint created for build provenance verification | Planning |
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
- **Decision**: SLSA as primary provenance framework
|
||||
- **Decision**: Reproducibility verification is opt-in (requires rebuild)
|
||||
- **Risk**: Not all build systems provide adequate provenance; mitigation is graceful degradation
|
||||
- **Risk**: Reproducibility verification is slow; mitigation is async/background processing
|
||||
- **Decision**: Trusted builder registry is configurable per organization
|
||||
|
||||
## Next Checkpoints
|
||||
|
||||
- TASK-019-002 completion: SLSA evaluation functional
|
||||
- TASK-019-007 completion: Reproducibility verification functional
|
||||
- TASK-019-009 completion: Integration complete
|
||||
- TASK-019-013 completion: Real-world validation

## Decisions & Risks
|
||||
|
||||
- **Decision**: Support both CycloneDX and SPDX 3.0.1 VEX formats
|
||||
- **Decision**: Default to trusting embedded VEX (producer-generated)
|
||||
- **Risk**: VEX may be stale; mitigation is timestamp validation
|
||||
- **Risk**: Conflicting VEX from multiple sources; mitigation is clear resolution policy
|
||||
- **Decision**: NotAffected filtering is configurable (default: filter)
|
||||
|
||||
## Next Checkpoints
|
||||
|

| Date (UTC) | Update | Owner |
|

| --- | --- | --- |
|

| 2026-01-19 | Sprint created for dependency reachability | Planning |
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
- **Decision**: SBOM-based reachability is coarse but widely applicable
|
||||
- **Decision**: Conservative approach - when uncertain, mark as PotentiallyReachable
|
||||
- **Risk**: SBOM may have incomplete dependency data; mitigation is Unknown status
|
||||
- **Risk**: Dynamic loading defeats static analysis; mitigation is PotentiallyReachable
|
||||
- **Decision**: Reduction metrics must be tracked to prove value
|
||||
|
||||
## Next Checkpoints
|
||||
|
||||
- TASK-022-004 completion: Static analysis functional
|
||||
- TASK-022-007 completion: ReachGraph integration
|
||||

| --- | --- | --- |
|

| 2026-01-19 | Sprint created for NTIA compliance | Planning |
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
- **Decision**: NTIA minimum elements as baseline, extend for other frameworks
|
||||
- **Decision**: Supplier validation is optional but recommended
|
||||
- **Risk**: Many SBOMs lack supplier information; mitigation is reporting gaps clearly
|
||||
- **Risk**: Placeholder values are common; mitigation is configurable detection
|
||||
- **Decision**: Compliance can be a release gate or advisory (configurable)
|
||||
|
||||
## Next Checkpoints
|
||||
|
||||
- TASK-023-002 completion: Baseline validation functional
|
||||
- TASK-023-004 completion: Supplier validation functional
|

| Date (UTC) | Update | Owner |
|
||||
| --- | --- | --- |
|

| 2026-01-20 | Sprint created for scanner license enhancements | Planning |
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
- **Decision**: Unified LicenseDetectionResult model for all languages
|
||||
- **Decision**: Categorization is best-effort, Policy module makes final decisions
|
||||
- **Risk**: License text extraction increases scan time; mitigation is opt-in/configurable
|
||||
- **Risk**: Some licenses hard to categorize; mitigation is Unknown category and manual override
|
||||
- **Decision**: Add JavaScript and .NET detectors to cover major ecosystems
|
||||
|
||||
## Next Checkpoints
|
||||
|
||||
- TASK-024-002 completion: Categorization service functional
|
||||
- TASK-024-008 completion: All existing detectors upgraded
|
||||
- TASK-024-011 completion: Evidence builder updated
|
||||
- TASK-024-015 completion: Real-world validation

# DeltaSig v2 Predicate Schema
|
||||
|
||||
> **Sprint**: SPRINT_20260119_004_BinaryIndex_deltasig_extensions
|
||||
> **Status**: Implemented
|
||||
|
||||
## Overview
|
||||
|
||||
DeltaSig v2 extends the function-level binary diff predicate with:
|
||||
|
||||
- **Symbol Provenance**: Links function matches to ground-truth corpus sources (debuginfod, ddeb, buildinfo, secdb)
|
||||
- **IR Diff References**: CAS-stored intermediate representation diffs for detailed analysis
|
||||
- **Explicit Verdicts**: Clear vulnerability status with confidence scores
|
||||
- **Function Match States**: Per-function vulnerable/patched/modified/unchanged classification
|
||||
|
||||
## Schema
|
||||
|
||||
**Predicate Type URI**: `https://stella-ops.org/predicates/deltasig/v2`
|
||||
|
||||
### Key Fields
|
||||
|
||||
| Field | Type | Description |
|
||||
|-------|------|-------------|
|
||||
| `schemaVersion` | string | Always `"2.0.0"` |
|
||||
| `subject` | object | Single subject (PURL, digest, arch) |
|
||||
| `functionMatches` | array | Function-level matches with evidence |
|
||||
| `verdict` | string | `vulnerable`, `patched`, `partial`, `unknown`, `partially_patched`, `inconclusive` |
|
||||
| `confidence` | number | 0.0-1.0 confidence score |
|
||||
| `summary` | object | Aggregate statistics |
|
||||
|
||||
### Function Match
|
||||
|
||||
```json
|
||||
{
|
||||
"functionId": "sha256:abc123...",
|
||||
"name": "ssl_handshake",
|
||||
"address": 4194304,
|
||||
"size": 256,
|
||||
"matchScore": 0.95,
|
||||
"matchMethod": "semantic_ksg",
|
||||
"matchState": "patched",
|
||||
"symbolProvenance": {
|
||||
"sourceId": "fedora-debuginfod",
|
||||
"observationId": "obs:gt:12345",
|
||||
"confidence": 0.98,
|
||||

|
||||
},
|
||||

```
|
||||
|
||||
### Summary
|
||||
|
||||
```json
|
||||
{
|
||||
"totalFunctions": 150,
|
||||
"vulnerableFunctions": 0,
|
||||
"patchedFunctions": 12,
|
||||
"unknownFunctions": 138,
|
||||
"functionsWithProvenance": 45,
|
||||
"functionsWithIrDiff": 12,
|
||||
"avgMatchScore": 0.85,

|
||||
"maxMatchScore": 0.99,
|
||||
"totalIrDiffSize": 1234
|
||||
}
|
||||
```
|
||||
|
||||
## Version Negotiation
|
||||
|
||||
Clients can request specific predicate versions:
|
||||
|
||||
```json
|
||||
{
|
||||
"preferredVersion": "2",
|
||||
"requiredFeatures": ["provenance", "ir-diff"]
|
||||
}
|
||||
```
|
||||
|
||||
Response:
|
||||
|
||||
```json
|
||||
{
|
||||
"version": "2.0.0",
|
||||
"predicateType": "https://stella-ops.org/predicates/deltasig/v2",
|
||||
"features": ["provenance", "ir-diff"]
|
||||
}
|
||||
```
|
||||
|
||||
## VEX Integration
|
||||
|
||||
DeltaSig v2 predicates can be converted to VEX observations via `IDeltaSigVexBridge`:
|
||||
|
||||
| DeltaSig Verdict | VEX Status |
|
||||
|------------------|------------|
|
||||
| `patched` | `fixed` |
|
||||
| `vulnerable` | `affected` |
|
||||
| `partially_patched` | `under_investigation` |
|
||||
| `inconclusive` | `under_investigation` |
|
||||
| `unknown` | `not_affected` (conservative) |
|
||||
|
||||
### Evidence Blocks
|
||||
|
||||
VEX observations include evidence blocks:
|
||||
|
||||
1. **deltasig-summary**: Aggregate statistics
|
||||
2. **deltasig-function-matches**: High-confidence matches with provenance
|
||||
3. **deltasig-predicate-ref**: Reference to full predicate
|
||||
|
||||
## Implementation
|
||||
|
||||
### Core Services
|
||||
|
||||
| Interface | Implementation | Description |
|
||||
|-----------|----------------|-------------|
|
||||
| `IDeltaSigServiceV2` | `DeltaSigServiceV2` | V2 predicate generation |
|
||||
| `ISymbolProvenanceResolver` | `GroundTruthProvenanceResolver` | Ground-truth lookup |
|
||||
| `IIrDiffGenerator` | `IrDiffGenerator` | IR diff generation with CAS |
|
||||
| `IDeltaSigVexBridge` | `DeltaSigVexBridge` | VEX observation generation |
|
||||
|
||||
### DI Registration
|
||||
|
||||
```csharp
|
||||
services.AddDeltaSigV2();
|
||||
```
|
||||
|
||||
Or with options:
|
||||
|
||||
```csharp
|
||||
services.AddDeltaSigV2(
|
||||
configureProvenance: opts => opts.IncludeStale = false,
|
||||
configureIrDiff: opts => opts.MaxParallelism = 4
|
||||
);
|
||||
```
|
||||
|
||||
## Migration from v1
|
||||
|
||||
Use `DeltaSigPredicateConverter`:
|
||||
|
||||
```csharp
|
||||
// v1 → v2
|
||||
var v2 = DeltaSigPredicateConverter.ToV2(v1Predicate);
|
||||
|
||||
// v2 → v1
|
||||
var v1 = DeltaSigPredicateConverter.ToV1(v2Predicate);
|
||||
```
|
||||
|
||||
Notes:
|
||||
- v1 → v2: Provenance and IR diff will be empty (add via resolver/generator)
|
||||
- v2 → v1: Provenance and IR diff are discarded; verdict/confidence are lost
|
||||

# Ground-Truth Corpus Architecture
|
||||
|
||||
> **Ownership:** BinaryIndex Guild
|
||||
> **Status:** DRAFT
|
||||
> **Version:** 1.0.0
|
||||
> **Related:** [BinaryIndex Architecture](architecture.md), [Corpus Management](corpus-management.md), [Concelier AOC](../concelier/guides/aggregation-only-contract.md)
|
||||
|
||||
---
|
||||
|
||||
## 1. Overview
|
||||
|
||||
The **Ground-Truth Corpus** system provides a validated function-matching oracle for binary diff accuracy measurement. It uses the same plugin-based ingestion pattern as Concelier (advisories) and Excititor (VEX), applying **Aggregation-Only Contract (AOC)** principles to ensure immutable, deterministic, and replayable data.
|
||||
|
||||
### 1.1 Problem Statement
|
||||
|
||||
Function matching and binary diffing require ground-truth data to measure accuracy:
|
||||
|
||||
1. **No oracle for validation** - How do we know a function match is correct?
|
||||
2. **Symbols stripped in production** - Debug info unavailable at scan time
|
||||
3. **Compiler/optimization variance** - Same source produces different binaries
|
||||
4. **Backport detection gaps** - Need pre/post pairs to validate patch detection
|
||||
|
||||
### 1.2 Solution: Distro Symbol Corpus
|
||||
|
||||
Leverage mainstream Linux distro artifacts as ground-truth:
|
||||
|
||||
| Source | What It Provides | Use Case |
|
||||
|--------|------------------|----------|
|
||||
| **Debian `.buildinfo`** | Exact build env records, often clearsigned | Reproducible oracle, build env metadata |
|
||||
| **Fedora Koji + debuginfod** | Machine-queryable debuginfo with IMA verification | Symbol recovery for stripped binaries |
|
||||
| **Ubuntu ddebs** | Debug symbol packages | Symbol-grounded truth for function names |
|
||||
| **Alpine SecDB** | Precise CVE-to-backport mappings | Pre/post pair curation |
|
||||
|
||||
### 1.3 Module Scope
|
||||
|
||||
**In Scope:**
|
||||
- Symbol recovery connectors (debuginfod, ddebs, .buildinfo)
|
||||
- Ground-truth observations (immutable, append-only)
|
||||
- Pre/post security pair curation
|
||||
- Validation harness for function-matching accuracy
|
||||
- Deterministic manifests for replayability
|
||||
|
||||
**Out of Scope:**
|
||||
- Function matching algorithms (see [semantic-diffing.md](semantic-diffing.md))
|
||||
- Fingerprint generation (see [corpus-management.md](corpus-management.md))
|
||||
- Policy decisions (provided by Policy Engine)

### 2.2 Component Breakdown
|
||||
|
||||
#### 2.2.1 Symbol Source Connectors
|
||||
|
||||
Plugin-based connectors following the Concelier `IFeedConnector` pattern:
|
||||
|
||||
```csharp
|
||||
public interface ISymbolSourceConnector
|
||||
{
|
||||
string SourceId { get; }
|
||||
string[] SupportedDistros { get; }
|
||||
|
||||
// Three-phase pipeline (matches Concelier pattern)
|
||||
Task FetchAsync(IServiceProvider sp, CancellationToken ct); // Download raw docs
|
||||
Task ParseAsync(IServiceProvider sp, CancellationToken ct); // Normalize to DTOs
|
||||
Task MapAsync(IServiceProvider sp, CancellationToken ct); // Build observations
|
||||
}
|
||||
```
|
||||
|
||||
**Implementations:**
|
||||
|
||||
| Connector | Source | Data Retrieved |
|
||||
|-----------|--------|----------------|
|
||||
| `DebuginfodConnector` | Fedora/RHEL debuginfod | ELF debuginfo, source files |
|
||||
| `DdebConnector` | Ubuntu ddebs repos | .ddeb packages with DWARF |
|
||||
| `BuildinfoConnector` | Debian .buildinfo | Build env, checksums, signatures |
|
||||
| `SecDbConnector` | Alpine SecDB | CVE-to-fix mappings |
|
||||
| `UpstreamConnector` | GitHub/tarballs | Upstream release sources |
|
||||
|
||||
#### 2.2.2 AOC Write Guard
|
||||
|
||||
Enforces aggregation-only invariants (mirrors `IAdvisoryObservationWriteGuard`):
|
||||
|
||||
```csharp
|
||||
public interface ISymbolObservationWriteGuard
|
||||
{
|
||||
WriteDisposition ValidateWrite(
|
||||
SymbolObservation candidate,
|
||||
string? existingContentHash);
|
||||
}
|
||||
|
||||
public enum WriteDisposition
|
||||
{
|
||||
Proceed, // Insert new observation
|
||||
SkipIdentical, // Idempotent re-insert, no-op
|
||||
RejectMutation // Reject (append-only violation)
|
||||
}
|
||||
```
|
||||
|
||||
**Invariants Enforced:**
|
||||
|
||||
| Invariant | What It Forbids |
|
||||
|-----------|-----------------|
|
||||
| No derived scores | Reject `confidence`, `accuracy`, `match_score` at ingest |
|
||||
| Immutable observations | No in-place updates; new revisions use `supersedes` |
|
||||
| Mandatory provenance | Require `source_url`, `fetched_at`, `content_hash`, `signature_state` |
|
||||
| Idempotent upserts | Key by `(source_id, debug_id, content_hash)` |
|
||||
| Deterministic canonical | Sorted JSON keys, UTC ISO-8601, stable hashes |
|
||||
|
||||
#### 2.2.3 Security Pair Curation
|
||||
|
||||
Manages pre/post CVE binary pairs for validation:
|
||||
|
||||
```csharp
|
||||
public interface ISecurityPairService
|
||||
{
|
||||
// Curate a pre/post pair for a CVE
|
||||
Task<SecurityPair> CreatePairAsync(
|
||||
string cveId,
|
||||
BinaryReference vulnerableBinary,
|
||||
BinaryReference patchedBinary,
|
||||
PairMetadata metadata,
|
||||
CancellationToken ct);
|
||||
|
||||
// Get pairs for validation
|
||||
Task<ImmutableArray<SecurityPair>> GetPairsAsync(
|
||||
SecurityPairQuery query,
|
||||
CancellationToken ct);
|
||||
}
|
||||
|
||||
public sealed record SecurityPair(
|
||||
string PairId,
|
||||
string CveId,
|
||||
BinaryReference VulnerableBinary,
|
||||
BinaryReference PatchedBinary,
|
||||
string[] AffectedFunctions, // Symbol names of vulnerable functions
|
||||
string[] ChangedFunctions, // Symbol names of patched functions
|
||||
DiffMetadata Diff, // Upstream patch info
|
||||
ProvenanceInfo Provenance);
|
||||
```
|
||||
|
||||
#### 2.2.4 Validation Harness
|
||||
|
||||
Runs function-matching validation with metrics:
|
||||
|
||||
```csharp
|
||||
public interface IValidationHarness
|
||||
{
|
||||
// Execute validation run
|
||||
Task<ValidationRun> RunAsync(
|
||||
ValidationConfig config,
|
||||
CancellationToken ct);
|
||||
|
||||
// Get metrics for a run
|
||||
Task<ValidationMetrics> GetMetricsAsync(
|
||||
Guid runId,
|
||||
CancellationToken ct);
|
||||
|
||||
// Export report
|
||||
Task<Stream> ExportReportAsync(
|
||||
Guid runId,
|
||||
ReportFormat format,
|
||||
CancellationToken ct);
|
||||
}
|
||||
|
||||
public sealed record ValidationMetrics(
|
||||
int TotalFunctions,
|
||||
int CorrectMatches,
|
||||
int FalsePositives,
|
||||
int FalseNegatives,
|
||||
int Unmatched,
|
||||
decimal MatchRate,
|
||||
decimal Precision,
|
||||
decimal Recall,
|

|
||||
## 5. Validation Pipeline
|
||||
|
||||
### 5.1 Harness Workflow
|
||||
|
||||
```
|
||||
1. Assemble
|
||||
└─> Given package + CVE, fetch: binaries, debuginfo, .buildinfo, upstream tarball
|
||||
|
||||
2. Recover Symbols
|
||||
└─> Resolve build-id → symbols via debuginfod/ddebs
|
||||
└─> Fallback: Debian rebuild from .buildinfo
|
||||
|
||||
3. Lift Functions
|
||||
└─> Batch-lift .text functions → IR
|
||||
└─> Cache per build-id
|
||||
|
||||
4. Fingerprint
|
||||
└─> Emit deterministic + fuzzy signatures
|
||||
└─> Store as JSON lines
|
||||
|
||||
5. Match
|
||||
└─> Pre→post function matching
|
||||
└─> Write row per function with scores
|
||||
|
||||
6. Score
|
||||
└─> Compute metrics (match rate, FP/FN, precision, recall)
|
||||
└─> Bucket mismatches by cause
|
||||
|
||||
7. Report
|
||||
└─> Markdown/HTML with tables + diffs
|
||||
└─> Attach env hashes and artifact URLs
|
||||
```
|
||||
|
||||
### 5.2 Metrics Tracked
|
||||
|
||||
| Metric | Description |
|
||||
|--------|-------------|
|
||||
| `match_rate` | Correct matches / total functions |
|
||||
| `precision` | True positives / (true positives + false positives) |
|
||||
| `recall` | True positives / (true positives + false negatives) |
|
||||
| `unmatched_rate` | Unmatched / total functions |
|
||||
|
||||
### 5.3 Mismatch Buckets
|
||||
|
||||
| Cause | Description | Mitigation |
|
||||
|-------|-------------|------------|
|
||||
| `inlining` | Function inlined, no direct match | Inline expansion in fingerprint |
|
||||
| `lto` | Link-time optimization changed structure | Cross-module fingerprints |
|
||||
| `optimization` | Different -O level | Semantic fingerprints |
|
||||
| `pic_thunk` | Position-independent code stubs | Filter PIC thunks |
|
||||
| `versioned_symbol` | GLIBC symbol versioning | Version-aware matching |
|
||||
| `renamed` | Symbol renamed (macro, alias) | Alias resolution |

## 8. Doctor Checks
|
||||
|
||||
The ground-truth corpus integrates with Doctor for availability checks:
|
||||
|
||||
```csharp
|
||||
// stellaops.doctor.binaryanalysis plugin
|
||||
public sealed class BinaryAnalysisDoctorPlugin : IDoctorPlugin
|
||||
{
|
||||
public string Name => "stellaops.doctor.binaryanalysis";
|
||||
|
||||
public IEnumerable<IDoctorCheck> GetChecks()
|

## 9. Air-Gap Support
|
||||
|
||||
For offline/air-gapped deployments:
|
||||
|
||||
### 9.1 Symbol Bundle Format
|
||||
|
||||
```
|
||||
symbol-bundle-2026-01-19/
|
||||
├── manifest.json # Bundle metadata + checksums
|
||||
├── sources/
|
||||
│ ├── debuginfod/
|
||||
│ │ └── *.debuginfo # Pre-fetched debuginfo
|
||||
│ ├── ddebs/
|
||||
│ │ └── *.ddeb # Pre-fetched ddebs
|
||||
│ └── buildinfo/
|
||||
│ └── *.buildinfo # Pre-fetched buildinfo
|
||||
├── observations/
|
||||
│ └── *.ndjson # Pre-computed observations
|
||||
└── DSSE.envelope # Signed attestation
|
||||
```
|
||||
|
||||
### 9.2 Offline Sync
|
||||
|
||||
```bash
|
||||

--packages openssl,zlib,glibc \
|
||||
--distros debian,fedora \
|
||||
--output symbol-bundle.tar.gz
|
||||
|
||||
# Import bundle in air-gapped environment
|
||||
stella groundtruth bundle import \
|
||||
--input symbol-bundle.tar.gz \
|
||||
--verify-signature
|

# GroundTruth.Abstractions - Agent Instructions
|
||||
|
||||
## Module Overview
|
||||
|
||||
This library defines the core abstractions for ground-truth symbol source connectors following the Concelier/Excititor Aggregation-Only Contract (AOC) pattern.
|
||||
|
||||
## Key Interfaces
|
||||
|
||||
- **ISymbolSourceConnector** - Main connector interface with three-phase pipeline (Fetch → Parse → Map)
|
||||
- **ISymbolSourceConnectorPlugin** - Plugin registration interface
|
||||
- **ISymbolObservationWriteGuard** - AOC enforcement for immutable observations
|
||||
- **ISymbolObservationRepository** - Persistence for observations
|
||||
- **ISecurityPairService** - Pre/post CVE binary pair management
|
||||
|
||||
## AOC Invariants (MUST follow)
|
||||
|
||||
1. **No derived scores at ingest** - Never add confidence, accuracy, or match_score during ingestion
|
||||
2. **Immutable observations** - Once created, observations are never modified
|
||||
3. **Supersession chain** - New versions use `SupersedesId` to link to previous
|
||||
4. **Mandatory provenance** - All observations must have `source_id`, `document_uri`, `fetched_at`, `content_hash`
|
||||
5. **Deterministic hashing** - Use canonical JSON with sorted keys, UTC timestamps, hex-lowercase hashes
|
||||
|
||||
## Adding New Connectors
|
||||
|
||||
1. Implement `ISymbolSourceConnector` (or extend `SymbolSourceConnectorBase`)
|
||||
2. Implement `ISymbolSourceConnectorPlugin` for DI registration
|
||||
3. Add source definition to `SymbolSourceDefinitions`
|
||||
4. Follow the three-phase pattern:
|
||||
- **Fetch**: Download raw data, store with digest, update cursor
|
||||
- **Parse**: Validate, extract symbols, create DTOs
|
||||
- **Map**: Build canonical observations, enforce AOC, persist
|
||||
|
||||
## Testing Requirements
|
||||
|
||||
- Unit tests for all public interfaces
|
||||
- AOC write guard tests for all violation codes
|
||||
- Deterministic hash tests with frozen fixtures
|
||||
- Offline-compatible test fixtures
|
||||
|
||||
## Dependencies
|
||||
|
||||
- Microsoft.Extensions.Logging.Abstractions
|
||||
- Microsoft.Extensions.Options
|
||||
- System.Text.Json

# GroundTruth.Buildinfo - Agent Instructions
|
||||
|
||||
## Module Overview
|
||||
|
||||
This library implements the Debian .buildinfo file connector for fetching reproducible build metadata from buildinfos.debian.net.
|
||||
|
||||
## Key Components
|
||||
|
||||
- **BuildinfoConnector** - Main connector implementing three-phase pipeline
|
||||
- **BuildinfoConnectorPlugin** - Plugin registration for DI discovery
|
||||
- **BuildinfoOptions** - Configuration options
|
||||
- **BuildinfoDiagnostics** - Metrics and telemetry
|
||||
- **BuildinfoParser** - Parser for RFC 822 format .buildinfo files
|
||||
|
||||
## Configuration
|
||||
|
||||
```csharp
|
||||
services.AddBuildinfoConnector(opts =>
|
||||
{
|
||||
opts.BaseUrl = new Uri("https://buildinfos.debian.net");
|
||||
opts.SnapshotUrl = new Uri("https://snapshot.debian.org");
|
||||
opts.Distributions = ["bookworm", "bullseye", "trixie"];
|
||||
opts.Architectures = ["amd64", "arm64"];
|
||||
opts.VerifySignatures = true;
|
||||
});
|
||||
```
|
||||
|
||||
## Three-Phase Pipeline
|
||||
|
||||
1. **Fetch**: Download .buildinfo files from buildinfos.debian.net
|
||||
2. **Parse**: Parse RFC 822 format, extract checksums, dependencies, build metadata
|
||||
3. **Map**: Build canonical observations for reproducible build verification
|
||||
|
||||
## .buildinfo File Structure
|
||||
|
||||
```
|
||||
Format: 1.0
|
||||
Source: package-name
|
||||
Binary: binary1 binary2
|
||||
Architecture: amd64
|
||||
Version: 1.0-1
|
||||
Checksums-Sha256:
|
||||
abc123... 12345 binary1_1.0-1_amd64.deb
|
||||
def456... 67890 binary2_1.0-1_amd64.deb
|
||||
Build-Origin: debian
|
||||
Build-Architecture: amd64
|
||||
Build-Date: Thu, 01 Jan 2024 12:00:00 +0000
|
||||
Build-Path: /build/package-1.0
|
||||
Installed-Build-Depends:
|
||||
gcc (= 12.2.0-14),
|
||||
libc6-dev (= 2.36-9)
|
||||
Environment:
|
||||
"DEB_BUILD_OPTIONS=nocheck"
|
||||
"LANG=C.UTF-8"
|
||||
```
|
||||
|
||||
## snapshot.debian.org Integration
|
||||
|
||||
The connector can fetch exact binary versions using SHA256 hashes from the .buildinfo file:
|
||||
|
||||
```
|
||||
https://snapshot.debian.org/file/{sha256hash}
|
||||
```
|
||||
|
||||
This enables retrieval of the exact binary that was produced during the recorded build.
|
||||
|
||||
## Testing
|
||||
|
||||
- Unit tests for BuildinfoParser
|
||||
- Integration tests require access to buildinfos.debian.net (skippable)
|
||||
- Deterministic fixtures with sample .buildinfo content
|
||||
|
||||
## Future Work
|
||||
|
||||
- GPG signature verification using debian-archive-keyring
|
||||
- Pagination through buildinfo index
|
||||
- Cross-reference with debug symbol sources
|
||||
- Reproducible build verification pipeline

# GroundTruth.Ddeb - Agent Instructions
|
||||
|
||||
## Module Overview
|
||||
|
||||
This library implements the Ubuntu ddeb debug symbol package connector for fetching debug symbols from Ubuntu's ddebs repository.
|
||||
|
||||
## Key Components
|
||||
|
||||
- **DdebConnector** - Main connector implementing three-phase pipeline
|
||||
- **DdebConnectorPlugin** - Plugin registration for DI discovery
|
||||
- **DdebOptions** - Configuration options
|
||||
- **DdebDiagnostics** - Metrics and telemetry
|
||||
- **PackagesIndexParser** - Parser for Debian Packages index files
|
||||
- **IDebPackageExtractor** - Interface for .ddeb package extraction
|
||||
|
||||
## Configuration
|
||||
|
||||
```csharp
|
||||
services.AddDdebConnector(opts =>
|
||||
{
|
||||
opts.MirrorUrl = new Uri("http://ddebs.ubuntu.com");
|
||||
opts.Distributions = ["focal", "jammy", "noble"];
|
||||
opts.Components = ["main", "universe"];
|
||||
opts.Architectures = ["amd64", "arm64"];
|
||||
});
|
||||
```
|
||||
|
||||
## Three-Phase Pipeline
|
||||
|
||||
1. **Fetch**: Download Packages.gz index, identify dbgsym packages, fetch .ddeb files
|
||||
2. **Parse**: Extract .ddeb archive (ar + tar.zst), parse DWARF from debug binaries
|
||||
3. **Map**: Build canonical SymbolObservation for each binary with AOC compliance
|
||||
|
||||
## Ubuntu Ddeb Repository Structure
|
||||
|
||||
```
|
||||
http://ddebs.ubuntu.com/
|
||||
├── dists/
|
||||
│ └── {dist}/ # focal, jammy, noble
|
||||
│ └── {component}/ # main, universe
|
||||
│ └── debug/
|
||||
│ └── binary-{arch}/
|
||||
│ └── Packages.gz
|
||||
└── pool/
|
||||
└── main/
|
||||
└── {first-letter}/
|
||||
└── {source-pkg}/
|
||||
└── {pkg}-dbgsym_{version}_{arch}.ddeb
|
||||
```
|
||||
|
||||
## .ddeb Package Structure
|
||||
|
||||
```
|
||||
package-dbgsym.ddeb (ar archive)
|
||||
├── debian-binary
|
||||
├── control.tar.xz
|
||||
└── data.tar.zst
|
||||
└── usr/lib/debug/
|
||||
└── .build-id/
|
||||
└── {first-2-hex}/
|
||||
└── {rest-of-build-id}.debug
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
- Unit tests for PackagesIndexParser
|
||||
- Integration tests require access to ddebs.ubuntu.com (skippable)
|
||||
- Deterministic fixtures with sample Packages index
|
||||
|
||||
## Future Work
|
||||
|
||||
- Implement real IDebPackageExtractor using ar/tar extraction
|
||||
- DWARF symbol parsing from debug binaries
|
||||
- Build-id to binary package correlation
|
||||
- GPG signature verification
