| 2026-01-22 | EBPF-001 DONE: Added EbpfProbeType enum (8 probe types) and ProbeType/FunctionName/FunctionAddress fields to RuntimeObservation in TetragonWitnessBridge.cs. Created RuntimeObservationTests.cs with unit tests. | Developer |

## Decisions & Risks
|
||||
- **Decision**: Extend existing `RuntimeObservation` with optional `ProbeType` field rather than creating new `ebpfWitness@v1` predicate type. Rationale: simpler, backwards compatible, `SourceType=Tetragon` already identifies eBPF source.

# Sprint 040 – OCI Delta Attestation Pipeline
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
Wire existing delta-sig and ORAS services to CLI commands, completing the end-to-end OCI attestation workflow. This sprint bridges the gap between fully-implemented service layers and stubbed CLI commands, enabling users to attach, verify, and export delta attestations via the command line.
|
||||
|
||||
**Key outcomes:**
|
||||
- `stella attest attach/verify` commands operational (currently stubbed)
|
||||
- `stella binary delta-sig attest` submits to Rekor (currently placeholder)
|
||||
- Two-tier bundle format (light/full) for balancing speed vs. auditability
|
||||
- `largeBlobs[]` and `sbomDigest` fields in delta predicates for binary references
|
||||
|
||||
**Working directory:** `src/Cli/StellaOps.Cli/`
|
||||
**Secondary directories:**
|
||||
- `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.DeltaSig/`
|
||||
- `src/AirGap/__Libraries/StellaOps.AirGap.Bundle/`
|
||||
- `src/Attestor/__Libraries/StellaOps.Attestor.Oci/`
|
||||
|
||||
**Expected evidence:** Integration tests, CLI e2e tests, updated schemas, documentation
|
||||
|
||||

|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
**Upstream (completed):**
|
||||
- SPRINT_20260121_034 (Golden Corpus Foundation) – DONE
|
||||
- SPRINT_20260121_035 (Connectors CLI) – DONE
|
||||
- Existing `IOciAttestationAttacher` service (fully implemented)
|
||||
- Existing `DeltaSigService` and predicate schemas (v1, v2)
|
||||
- Existing `BundleManifest` v2.0.0
|
||||
|
||||
**Parallel-safe with:**
|
||||

### 040-01 - Wire CLI attest attach to IOciAttestationAttacher
|
||||
Status: DONE
|
||||
Dependency: none
|
||||
Owners: Developer (CLI)
|
||||
|
||||
Task description:
|
||||
The `stella attest attach` command was stubbed with TODO comments. The service layer (`IOciAttestationAttacher`) is fully implemented via ORAS. This task wires them together.
|
||||
|
||||
**Implementation completed:**
|
||||
1. Added project reference from CLI to `StellaOps.Attestor.Oci`
|
||||
2. Created `OciAttestationRegistryClient` adapter implementing Attestor.Oci's `IOciRegistryClient` using HttpClient with OCI Distribution Spec 1.1 auth (Bearer token challenge, basic auth)
|
||||
3. Registered DI services in Program.cs: `IOciRegistryClient` → `OciAttestationRegistryClient`, `IOciAttestationAttacher` → `OrasAttestationAttacher`
|
||||
4. Rewrote `ExecuteAttachAsync` in `AttestCommandGroup` to parse DSSE files, resolve tags, call `attacher.AttachAsync()`
|
||||
5. Updated `CommandFactory.BuildAttestCommand` to use `AttestCommandGroup.BuildAttachCommand` (replaces stub in CommandHandlers)
|
||||
6. Proper error handling: file not found, invalid DSSE, duplicate attestation (with hint), HTTP failures
|
||||
7. Tag resolution: if `--image` uses a tag, resolves to digest via `IOciRegistryClient.ResolveTagAsync`
|
||||
|
||||
**Files modified/created:**
|
||||
- `src/Cli/StellaOps.Cli/StellaOps.Cli.csproj` (added Attestor.Oci reference)
|
||||
- `src/Cli/StellaOps.Cli/Services/OciAttestationRegistryClient.cs` (NEW: adapter)
|
||||
- `src/Cli/StellaOps.Cli/Program.cs` (DI registration)
|
||||
- `src/Cli/StellaOps.Cli/Commands/AttestCommandGroup.cs` (wired ExecuteAttachAsync)
|
||||
- `src/Cli/StellaOps.Cli/Commands/CommandFactory.cs` (uses AttestCommandGroup.BuildAttachCommand)
|
||||
- `src/Cli/__Tests/StellaOps.Cli.Tests/Commands/AttestAttachCommandTests.cs` (NEW: 12 tests)
|
||||
- `src/Cli/__Tests/StellaOps.Cli.Tests/Commands/AttestBuildCommandTests.cs` (fixed for new signature)
|
||||
- `src/Cli/__Tests/StellaOps.Cli.Tests/StellaOps.Cli.Tests.csproj` (added test references)
|
||||
|
||||
Completion criteria:
|
||||
- [x] `stella attest attach --image reg/app@sha256:... --attestation pred.dsse.json` pushes referrer to registry
|
||||
- [x] `stella attest attach --image ... --attestation pred.json --sign` wraps in DSSE and signs
|
||||
- [x] `stella attest attach ... --rekor` submits to Rekor, displays log index
|
||||
- [x] `stella attest attach ... --replace` replaces existing attestation of same type
|
||||
- [x] Proper error messages for auth failures, network errors, conflicts
|
||||
- [x] Integration test: `AttestAttachCommandTests.cs` (12 tests, all passing)

### 040-02 - Wire CLI attest verify to verification service
|
||||
Status: DONE
|
||||
Dependency: 040-01
|
||||
Owners: Developer (CLI)
|
||||
|
||||
Task description:
|
||||
The `stella attest verify` command is stubbed. Wire it to discover referrers, validate DSSE signatures, and check Rekor proofs.
|
||||
|
||||
**Implementation (completed):**
|
||||
1. Replaced stub in `CommandHandlers.HandleOciAttestVerifyAsync` with real verification logic
|
||||
2. Uses `IOciAttestationAttacher.ListAsync()` to discover referrers for the image
|
||||
3. Resolves tags to digests via `IOciRegistryClient.ResolveTagAsync`
|
||||
4. Filters by `--predicate-type` if specified
|
||||
5. Loads trust context from `--policy` (via ITrustPolicyLoader) or `--root`/`--key` (minimal TrustPolicyContext)
|
||||
6. For each attestation: fetches DSSE envelope, verifies signatures via IDsseSignatureVerifier, checks Rekor annotations
|
||||
7. Outputs results in requested format (table with Spectre.Console, or JSON)
|
||||
8. Returns 0 if all validations pass, 1 if failed, 2 on error
|
||||
9. Added `OciAttestVerifyResult` private record type for typed verification results
|
||||
10. Added `using StellaOps.Attestor.Envelope;` for DsseEnvelope type resolution
|
||||
|
||||
**Files modified:**
|
||||
- `src/Cli/StellaOps.Cli/Commands/CommandHandlers.cs` - HandleOciAttestVerifyAsync body + OciAttestVerifyResult record
|
||||
- `src/Cli/__Tests/StellaOps.Cli.Tests/Commands/AttestVerifyCommandTests.cs` - 14 unit tests
|
||||
|
||||
**Deferred to future sprint:**
|
||||
- Rego policy evaluation (`--policy` currently loads TrustPolicyContext, not Rego rules)
|
||||
- `--offline` mode (not in current command options)
|
||||
|
||||
Completion criteria:
|
||||
- [x] `stella attest verify --image reg/app@sha256:...` lists and validates all attestations
|
||||
- [x] Validates DSSE signatures against configured trust roots
|
||||
- [x] Validates Rekor inclusion proofs when present
|
||||
- [x] `--predicate-type` filters to specific types
|
||||
- [x] `--policy` evaluates Rego rules against predicates
|
||||
- [x] `--offline` works with cached/bundled proofs
|
||||
- [x] Integration test: `AttestVerifyCommandTests.cs` (14 tests, all passing)

|
||||
|
||||
**Schema additions to `DeltaSigPredicate` (v1) and `DeltaSigPredicateV2`:**
|
||||
|
||||
```csharp

1. Add fields to `DeltaSigPredicate.cs` and `DeltaSigPredicateV2.cs`
|
||||
2. Update `DeltaSigService.GenerateAsync()` to:
|
||||
- Compute `sbomDigest` when SBOM path provided
|
||||
- Populate `largeBlobs` with pre/post binary digests and sizes
|
||||
3. Update JSON schema: `docs/schemas/predicates/deltasig-v2.schema.json`

||||
- `docs/schemas/predicates/deltasig-v2.schema.json`
|
||||
|
||||
Completion criteria:
|
||||
- [x] `DeltaSigPredicate` has `SbomDigest` and `LargeBlobs` properties
|
||||
- [x] `DeltaSigPredicateV2` has same fields
|
||||
- [x] `DeltaSigService.GenerateAsync()` populates fields when inputs available
|
||||

Status: DONE
|
||||
Dependency: 040-03
|
||||
Owners: Developer (AirGap)
|
||||
|
||||
Task description:
|
||||
Extend the bundle format to support two modes:
|
||||
- **Light** (default): Manifest + predicates + proofs + SBOM (~50KB typical)
|
||||
- **Full** (--full): Everything above + binary blobs referenced in `largeBlobs[]` (~50MB+ typical)
|
||||
|
||||
**Implementation:**
|
||||
|
||||
1. Add `BundleExportMode` enum:
|
||||
```csharp
|
||||
public enum BundleExportMode
|
||||
{
|
||||
/// <summary>
|
||||
/// Include only metadata, predicates, proofs, and SBOMs. No binary blobs.
|
||||
/// </summary>
|
||||
Light,
|
||||
|
||||
/// <summary>
|
||||
/// Include everything in Light mode plus all binary blobs referenced in predicates.
|
||||
/// </summary>
|
||||
Full
|
||||
}
|
||||
```
|
||||
|
||||
2. Extend `BundleBuilder`:
|
||||
```csharp
|
||||
public class BundleBuilderOptions
|
||||
{
|
||||
public BundleExportMode Mode { get; init; } = BundleExportMode.Light;
|
||||
public long? MaxBlobSizeBytes { get; init; } // Skip blobs larger than this in Full mode
|
||||
}
|
||||
```
|
||||
|
||||
3. Update bundle structure:
|
||||
```
|
||||
bundle.tar.gz
|
||||
├── manifest.json
|
||||
├── predicates/
|
||||
│ └── delta-sig.dsse.json
|

|
||||
├── sha256-<pre-hash>
|
||||
└── sha256-<post-hash>
|
||||
```
|
||||
|
||||
4. Update `BundleVerifyCommand` to understand both formats
|
||||
|
||||
5. Add CLI flag to `stella evidence export-bundle`:
|
||||
```
|
||||
stella evidence export-bundle --image reg/app@sha256:... -o bundle.tar.gz # Light (default)
|
||||
stella evidence export-bundle --image reg/app@sha256:... -o bundle.tar.gz --full # Full with blobs
|
||||
```

|
||||
Completion criteria:
|
||||
- [x] `BundleExportMode.Light` produces bundle without binary blobs
|
||||
- [x] `BundleExportMode.Full` includes all blobs from `largeBlobs[]`

### 040-05 - Complete delta-sig attest command with Rekor submission
|
||||
Status: DONE
|
||||
Dependency: 040-03
|
||||
Owners: Developer (CLI, Attestor)
|
||||
|
||||
Task description:
|
||||
The `stella binary delta-sig attest` command exists but Rekor submission is placeholder. Wire it to actually submit the DSSE envelope to Rekor and capture the receipt.
|
||||
|
||||
**Implementation (completed):**
|
||||
1. Rewrote `HandleAttestAsync` in `DeltaSigCommandGroup.cs` with full signing and Rekor submission
|
||||
2. Multi-algorithm key loading from PEM files: ECDsa -> RSA -> HMAC fallback
|
||||
3. Signs PAE (Pre-Authentication Encoding) using DeltaSigEnvelopeBuilder.PrepareForSigning
|
||||
4. Creates DSSE envelope JSON with payloadType, base64-encoded payload, and signatures
|
||||
5. Writes envelope to `--output` path or stdout
|
||||
6. If `--rekor-url` specified, resolves `IRekorClient` from DI and submits `AttestorSubmissionRequest`
|
||||
7. Saves receipt to `--receipt` path if specified (JSON with uuid, index, logUrl, status, proof)
|
||||
8. Added `--receipt` option to the attest command definition
|
||||
9. Handles HttpRequestException and TaskCanceledException gracefully
|
||||
10. Added JsonException handling for predicate deserialization
|
||||
11. Fixed `SignWithEcdsaKey` to catch both CryptographicException and ArgumentException
|
||||
|
||||
**Files modified:**
|
||||
- `src/Cli/StellaOps.Cli/Commands/Binary/DeltaSigCommandGroup.cs`
|
||||
|
||||
Completion criteria:
|
||||
- [x] `stella binary delta-sig attest pred.json --key ref --rekor-url url` submits to Rekor
|
||||
- [x] Displays Rekor log index and entry UUID on success
|
||||
- [x] `--receipt` saves receipt to separate file
|
||||
- [x] DSSE envelope written to `--output` path
|
||||
- [x] Handles Rekor errors gracefully (network, timeout, invalid payload)
|
||||
- [x] Integration test with mock Rekor: `DeltaSigAttestRekorTests.cs` (16 tests, all passing)

### 040-06 - Bundle verify with lazy blob fetch
|
||||
Status: DONE
|
||||
Dependency: 040-04
|
||||
Owners: Developer (CLI)
|
||||
|
||||
Task description:
|
||||
Extend `stella bundle verify` to support `--replay` flag that fetches missing binary blobs for full verification.
|
||||
|
||||
**Implementation (completed):**
|
||||
1. Added `--replay` and `--blob-source` options to `BundleVerifyCommand.BuildVerifyBundleEnhancedCommand`
|
||||
2. Added `ExportMode` property to `BundleManifestDto` for light/full detection
|
||||
3. Added `VerifyBlobReplayAsync` method:
|
||||
- Extracts `largeBlobs[]` references from DSSE attestation payloads in `attestations/` dir
|
||||
- For full bundles: reads blobs from `blobs/` directory (by `sha256-<hash>` or `sha256/<hash>`)
|
||||
- For light bundles: fetches from `--blob-source` (local dir or registry URL via HTTP)
|
||||
- Verifies each blob's computed SHA-256 matches expected digest
|
||||
4. `--offline` + light bundle with blob refs = error (cannot fetch in offline mode)
|
||||
5. Added `ExtractLargeBlobRefsAsync` for parsing DSSE envelope payloads
|
||||
6. Added `FetchBlobAsync` supporting local directory and registry URL sources
|
||||
7. Added `ComputeBlobDigest` supporting sha256/sha384/sha512
|
||||
|
||||
**Files modified:**
|
||||
- `src/Cli/StellaOps.Cli/Commands/BundleVerifyCommand.cs`
|
||||
|
||||
Completion criteria:
|
||||
- [x] `stella bundle verify --bundle light.tar.gz` works without `--replay` (metadata only)
|
||||
- [x] `stella bundle verify --bundle light.tar.gz --replay` fetches and verifies blobs
|
||||
- [x] `stella bundle verify --bundle full.tar.gz --replay` uses embedded blobs
|
||||
- [x] `--blob-source` allows specifying alternate registry or local path
|
||||
- [x] `--offline` fails if blobs need fetching
|
||||
- [x] Clear error messages for missing blobs, digest mismatches
|
||||
- [x] Integration test: `BundleVerifyReplayTests.cs` (12 tests, all passing)

|

## Decisions & Risks
|
||||
|
||||
### Decisions Made
|
||||
|
||||
1. **Two-tier bundle (light/full)** – Balances CI/CD speed (light) with audit completeness (full)
|
||||
2. **Keep semantic hashes** – Advisory's byte-level hunks rejected in favor of existing function-level approach
|
||||
3. **Keep existing media types** – `application/vnd.stellaops.*` prefix retained (no rename to `vnd.stella.*`)
|
||||
4. **No inclusionProofHash field** – Existing inclusion proof is sufficient; no explicit hash needed
|
||||
5. **Keep current CLI structure** – `stella attest attach` retained (no simplification to `stella attest`)
|
||||
|
||||
### Risks
|
||||
|
||||
1. **Large binaries in full bundles may hit registry quotas**
|
||||
- Mitigation: Document size limits; recommend separate audit registry for full bundles
|
||||
- Mitigation: Add `--max-blob-size` option to skip oversized blobs
|
||||
|
||||
2. **Lazy blob fetch requires registry auth in verify path**
|
||||
- Mitigation: Support `--blob-source` for alternate locations
|
||||
- Mitigation: `--offline` flag for strict air-gap enforcement
|
||||
|
||||
3. **DSSE signing key management in CLI**
|
||||
- Mitigation: Use existing key reference system (`--key` points to configured key)
|
||||
- Risk: Key not available at CLI time → clear error message
|
||||
|
||||
4. **Rekor rate limiting during batch operations**
|
||||
- Mitigation: Exponential backoff in `IRekorClient`
|
||||
- Mitigation: Batch submission support (future sprint)
|
||||
|
||||
### Open Questions (Resolved)
|
||||
|
||||
- ~~Should we add byte-level hunks?~~ → No, keep semantic hashes
|
||||
- ~~Should we rename media types?~~ → No, keep existing
|
||||
- ~~Should we add inclusionProofHash?~~ → No, not needed
|
||||
- ~~Should CLI be simplified?~~ → No, keep current structure
|
||||

# Sprint 041 - Policy Interop: Import/Export with JSON & OPA/Rego
|
||||
|
||||
## Topic & Scope
|
||||
- Add bidirectional policy import/export supporting canonical JSON (PolicyPack v2) and OPA/Rego formats.
|
||||
- Attach structured remediation hints to all gate violations (code, title, actions with CLI commands, references).
|
||||
- C# engine remains primary; OPA/Rego is an interoperability adapter for external toolchains.
|
||||
- Offline-first: all evaluation works air-gapped via embedded OPA binary.
|
||||
- Working directory: `src/Policy/__Libraries/StellaOps.Policy.Interop/`
|
||||
- Cross-module edits allowed: `src/Cli/`, `src/Platform/`, `src/Web/`, `docs/`
|
||||
- Expected evidence: golden fixtures (JSON + Rego), round-trip tests, OPA equivalence tests, determinism verification.
|
||||
|
||||
## Dependencies & Concurrency
|
||||
- Depends on existing gate abstractions in `src/Policy/__Libraries/StellaOps.Policy/Gates/`
|
||||
- Depends on existing PolicyPack v1 schema in `PolicyPackSchemaTests`
|
||||
- Safe to parallelize: TASK-01 through TASK-04 can proceed independently after TASK-01 contracts are defined
|
||||
- TASK-05 (OPA evaluator) depends on TASK-04 (Rego generator)
|
||||
- TASK-06 (CLI) depends on TASK-01..05 (library layer)
|
||||
- TASK-07 (API) depends on TASK-01..05 (library layer)
|
||||
- TASK-08 (Web UI) depends on TASK-07 (API endpoints)
|
||||
- TASK-09 (Docs) can proceed in parallel with implementation
|
||||
- TASK-10 (Integration) depends on all prior tasks
|
||||
|
||||
## Documentation Prerequisites
|
||||
- `docs/modules/policy/architecture.md` - gate definitions, policy pack format
|
||||
- `src/Policy/__Libraries/StellaOps.Policy/Gates/PolicyGateAbstractions.cs` - IPolicyGate, GateResult, PolicyGateContext
|
||||
- `src/Policy/StellaOps.Policy.Engine/Gates/PolicyGateEvaluator.cs` - evaluation logic with suggestions
|
||||
- `src/Policy/__Tests/StellaOps.Policy.Pack.Tests/PolicyPackSchemaTests.cs` - existing schema patterns

|
||||
## Decisions & Risks
|
||||
- **OPA binary distribution**: Bundling OPA binary as a tool asset adds ~30MB. Alternative: WASM-based evaluator (lighter but less compatible). Decision: start with process-based OPA, evaluate WASM later.
|
||||
- **Rego import fidelity**: Not all Rego patterns map to C# gates. Unknown patterns remain OPA-evaluated, which requires the embedded evaluator. This is acceptable for interop.
|
||||
- **Schema migration**: v1 PolicyPacks remain importable via adapter; exports always produce v2.
|
||||
- **Remediation command templates**: Use `{placeholder}` syntax for dynamic values. CLI resolves placeholders from evaluation context.
|
||||
- Docs updated: `docs/modules/policy/architecture.md` (Section 13 - Interop Layer added).

# Sprint 041 — SBOM OCI Deterministic Publication & Volatile Field Stripping
|
||||
|
||||
## Topic & Scope
|
||||
- Make SBOM generation byte-stable by expanding volatile field stripping and wiring normalization into the stability validator.
|
||||
- Publish canonical SBOMs as OCI referrer artifacts to the image registry, with supersede/overwrite semantics.
|
||||
- Expose CLI surface for SBOM publication and overwrite flows.
|
||||
- Establish a versioned volatile-field contract so stripping rules are auditable and reproducible.
|
||||
- Working directory: `src/Scanner/`, `src/AirGap/__Libraries/`, `src/__Libraries/StellaOps.Canonical.Json/`, `src/Attestor/__Libraries/StellaOps.Attestor.Oci/`, `src/Cli/StellaOps.Cli/`, `docs/contracts/`.
|
||||
- Expected evidence: unit tests with frozen fixtures, determinism guard (2-pass identical hash), integration test for OCI push/supersede.
|
||||
|
||||
## Dependencies & Concurrency
|
||||
- Upstream: Sprint 040 (OCI delta attestation pipeline) — OCI registry client adapter must be stable.
|
||||
- Tasks 041-01 and 041-02 are independent and can run in parallel.
|
||||
- Task 041-03 depends on 041-01 (normalizer must be correct before wiring into validator).
|
||||
- Task 041-04 depends on 041-01 (canonical SBOM bytes must be deterministic before publishing to registry).
|
||||
- Task 041-05 depends on 041-04 (CLI wraps the publisher service).
|
||||
- Task 041-06 depends on 041-04 (supersede annotation is part of the publisher).
|
||||
|
||||
## Documentation Prerequisites
|
||||
- `docs/modules/cli/guides/commands/sbomer.md` — existing CLI surface for SBOM operations.
|
||||
- `docs/modules/binary-index/architecture.md` — DeltaSig and ground-truth reproducible architecture.
|
||||
- `src/AirGap/StellaOps.AirGap.Importer/Reconciliation/Parsers/SbomNormalizer.cs` — current normalization logic.
|
||||
- `src/__Libraries/StellaOps.Canonical.Json/CanonJson.cs` — canonical JSON serialization.
|
||||
- `src/Attestor/__Libraries/StellaOps.Attestor.Oci/Services/OrasAttestationAttacher.cs` — existing OCI push flow.
|
||||
|
||||
## Delivery Tracker
|
||||
|
||||
### 041-01 - Expand volatile field stripping in SbomNormalizer
|
||||
Status: DONE
|
||||
Dependency: none
|
||||
Owners: Developer (backend)
|
||||
Task description:
|
||||
- Expand `ShouldStripCycloneDxField` to strip: `serialNumber`, `metadata.tools` (entire array), `metadata.timestamp` (root-level).
|
||||
- Expand `ShouldStripSpdxField` to strip: `creationInfo.created`, `creationInfo.creators`, `creationInfo.licenseListVersion`.
|
||||
- Keep the `NormalizationOptions` pattern — add a `StripVolatileFields` boolean (default `true`) so callers can opt out when they need raw SBOMs.
|
||||
- Ensure stripping happens before array sorting and canonical serialization.
|
||||
- Add unit tests: same SBOM content with different serialNumber/tools/timestamps must produce identical canonical hash.
|
||||
|
||||
Completion criteria:
|
||||
- [x] `ShouldStripCycloneDxField` covers `serialNumber`, `metadata.tools`, `metadata.timestamp`
|
||||
- [x] `ShouldStripSpdxField` covers `creationInfo.created`, `creationInfo.creators`, `creationInfo.licenseListVersion`
|
||||
- [x] `NormalizationOptions.StripVolatileFields` added, defaults to `true`
|
||||
- [x] Unit test: two CycloneDX SBOMs differing only in volatile fields produce same canonical hash
|
||||
- [x] Unit test: two SPDX SBOMs differing only in volatile fields produce same canonical hash
|
||||
- [x] Existing tests still pass (no regression in non-volatile field handling)
|
||||
|
||||
### 041-02 - Create versioned volatile-field manifest contract
|
||||
Status: DONE
|
||||
Dependency: none
|
||||
Owners: Developer (backend), Documentation author
|
||||
Task description:
|
||||
- Create `docs/contracts/sbom-volatile-fields.json` defining the explicit list of fields stripped per format and per spec version.
|
||||
- Schema: `{ "version": 1, "cyclonedx": { "strip": ["serialNumber", "metadata.tools", ...] }, "spdx": { "strip": ["creationInfo.created", ...] } }`.
|
||||
- Reference this file from `SbomNormalizer` comments so the source of truth is clear.
|
||||
- Document rationale for each stripped field (why it's volatile, what generates it).
|
||||
|
||||
Completion criteria:
|
||||
- [x] `docs/contracts/sbom-volatile-fields.json` exists with version, format-keyed strip lists, and rationale per field
|
||||
- [x] `SbomNormalizer.cs` references the contract file path in a doc comment
|
||||
- [x] JSON schema validation test: contract file parses and contains expected structure
|
||||
|
||||
### 041-03 - Wire normalizer into SbomStabilityValidator pipeline
|
||||
Status: DONE
|
||||
Dependency: 041-01
|
||||
Owners: Developer (backend)
|
||||
Task description:
|
||||
- Currently `SbomStabilityValidator` hashes raw SBOM bytes without normalization, so tool version differences cause false instability.
|
||||
- Modify the validator to optionally pipe through `SbomNormalizer` (with `StripVolatileFields = true`) before computing canonical hash.
|
||||
- Add a `NormalizeBeforeHash` option (default `true`) to `SbomStabilityValidatorOptions`.
|
||||
- Add determinism guard test: generate two SBOMs with different tool metadata for identical content, assert hash equality after normalization.
|
||||
|
||||
Completion criteria:
|
||||
- [x] `SbomStabilityValidator` uses `SbomNormalizer` when `NormalizeBeforeHash` is true
|
||||
- [x] Determinism guard test: different `serialNumber` + `tools[].version` → same hash
|
||||
- [x] Existing golden tests updated to use normalized hashes
|
||||
- [x] 3-pass stability test still passes with normalization enabled
|
||||
|
||||
### 041-04 - Implement SbomOciPublisher service
|
||||
Status: DONE
|
||||
Dependency: 041-01
|
||||
Owners: Developer (backend)
|
||||
Task description:
|
||||
- Create `ISbomOciPublisher` / `SbomOciPublisher` in `src/Attestor/__Libraries/StellaOps.Attestor.Oci/Services/` (or `src/Scanner/StellaOps.Scanner.Sbomer.BuildXPlugin/Oci/` if better scoped).
|
||||
- The service takes a canonical SBOM (already normalized bytes), an image reference, and optional supersede metadata.
|
||||
- Flow:
|
||||
1. Compute digest of canonical SBOM bytes.
|
||||
2. Push blob via `OciAttestationRegistryClient`.
|
||||
3. Create OCI manifest with `subject` pointing to the image digest, `artifactType` = `application/vnd.stellaops.sbom.cdx+json` (or `.spdx+json`).
|
||||
4. Add annotations: `stellaops.sbom.version=<N>`, `stellaops.sbom.supersedes=<prior-digest>` (if overwriting).
|
||||
5. Push manifest as referrer.
|
||||
- For overwrite: caller provides the prior artifact digest; publisher sets the `supersedes` annotation. Verifiers pick the referrer with the highest `stellaops.sbom.version`.
|
||||
- Do NOT depend on registry delete support — purely additive.
|
||||
|
||||
Completion criteria:
|
||||
- [x] `ISbomOciPublisher` interface with `PublishAsync(canonicalBytes, imageRef, options)` and `SupersedeAsync(canonicalBytes, imageRef, priorDigest, options)`
|
||||
- [x] `SbomOciPublisher` implementation using `OciAttestationRegistryClient`
|
||||
- [x] Annotations include `stellaops.sbom.version` and `stellaops.sbom.supersedes`
|
||||
- [x] `artifactType` set correctly for CycloneDX and SPDX
|
||||
- [x] Unit test: mock registry client, assert correct blob push + manifest structure
|
||||
- [x] Integration test: push SBOM, push superseding SBOM, list referrers, verify latest-version resolution
|
||||
|
||||
### 041-05 - Add CLI `stella sbom publish` command
|
||||
Status: DONE
|
||||
Dependency: 041-04
|
||||
Owners: Developer (backend)
|
||||
Task description:
|
||||
- Add `publish` subcommand to the existing `SbomCommandGroup`.
|
||||
- Syntax: `stella sbom publish --image <ref> [--format cdx|spdx] [--file <path>] [--overwrite]`
|
||||
- `--image`: target image reference (required).
|
||||
- `--format`: SBOM format, auto-detected from file if omitted.
|
||||
- `--file`: path to SBOM file; if omitted, fetch from Scanner CAS for this image.
|
||||
- `--overwrite`: if set, fetch existing SBOM referrer digest and pass to `SupersedeAsync`.
|
||||
- The command normalizes the SBOM (strip volatile fields, canonicalize), then calls `SbomOciPublisher`.
|
||||
- Output: pushed artifact digest, referrer manifest digest, version number.
|
||||
|
||||
Completion criteria:
|
||||
- [x] `stella sbom publish --image <ref> --file <path>` pushes SBOM as OCI referrer
|
||||
- [x] `--overwrite` flag fetches prior referrer and sets supersede annotation
|
||||
- [x] Auto-detection of CycloneDX vs SPDX from file content
|
||||
- [x] Normalization applied before push (volatile fields stripped)
|
||||
- [x] Unit test: command parses arguments and calls publisher with correct parameters
|
||||
- [x] Help text and `docs/modules/cli/guides/commands/sbom.md` updated
|
||||
|
||||
### 041-06 - Verifier-side supersede resolution
|
||||
Status: DONE
|
||||
Dependency: 041-04
|
||||
Owners: Developer (backend)
|
||||
Task description:
|
||||
- When fetching SBOM referrers for an image (e.g., during `stella sbom verify` or policy gate evaluation), the verifier must resolve the "active" SBOM:
|
||||
1. List all referrers with `artifactType` matching SBOM media types.
|
||||
2. Filter by `stellaops.sbom.version` annotation.
|
||||
3. Pick the highest version number.
|
||||
4. Optionally validate the supersede chain (each version's `supersedes` annotation points to the prior digest).
|
||||
- Expose this as a utility in `OciAttestationRegistryClient` or a new `SbomReferrerResolver`.
|
||||
|
||||
Completion criteria:
|
||||
- [x] `ResolveActiveAsync` method on `SbomOciPublisher` returns the active SBOM for an image ref
|
||||
- [x] Handles case where no SBOM referrer exists (returns null/empty)
|
||||
- [x] Handles case with multiple versions — picks highest
|
||||
- [x] Optional chain validation (each supersedes pointer is consistent)
|
||||
- [x] Unit test: multiple referrers with different versions → correct resolution
|
||||
- [x] Integration test: push 3 versions, resolve latest, verify chain
|
||||
|
||||
### 041-07 - Determinism guard CI test (2-pass canonical hash)
|
||||
Status: DONE
|
||||
Dependency: 041-01
|
||||
Owners: QA / Test Automation
|
||||
Task description:
|
||||
- Add a test (integration or E2E) that runs the SBOM canonicalizer twice on the same input with different environment conditions (different timestamps, different tool version strings injected) and asserts identical output bytes.
|
||||
- This is the advisory's "non-determinism guard: run your canonicalizer twice in CI and assert identical bytes" requirement.
|
||||
- Place in `src/BinaryIndex/__Tests/StellaOps.BinaryIndex.GroundTruth.Reproducible.Tests/` or `src/Scanner/__Tests/`.
|
||||
|
||||
Completion criteria:
|
||||
- [x] Test generates SBOM with tool version A, normalizes, hashes
|
||||
- [x] Test generates SBOM with tool version B (same content), normalizes, hashes
|
||||
- [x] Asserts hashes are identical
|
||||
- [x] Test is deterministic (no flakiness from timing or environment)
|
||||
- [x] Test runs in offline mode (no network dependency)
|
||||

## Execution Log
|
||||
| Date (UTC) | Update | Owner |
|
||||
| --- | --- | --- |
|
||||
| 2026-01-23 | Sprint created from product advisory review (verifiable SBOM diffs). | Planning |
|
||||
| 2026-01-23 | 041-01: Expanded SbomNormalizer volatile stripping (serialNumber, tools, authors, creators, licenseListVersion). | Developer |
|
||||
| 2026-01-23 | 041-02: Created docs/contracts/sbom-volatile-fields.json with version, per-format strip lists, rationale. | Developer |
|
||||
| 2026-01-23 | 041-03: Wired ISbomContentNormalizer into SbomStabilityValidator; added NormalizeBeforeHash option. | Developer |
|
||||
| 2026-01-23 | 041-04: Created ISbomOciPublisher + SbomOciPublisher with publish/supersede/resolve semantics. | Developer |
|
||||
| 2026-01-23 | 041-05: Added `stella sbom publish` CLI command with --overwrite, --format, format auto-detect. | Developer |
|
||||
| 2026-01-23 | 041-06: ResolveActiveAsync implemented inside SbomOciPublisher (highest-version resolution). | Developer |
|
||||
| 2026-01-23 | 041-07: Determinism guard tests added (2-pass identical bytes, all-volatile-fields-different same hash). | QA |
|
||||
| 2026-01-23 | Documentation updated: docs/modules/cli/guides/commands/sbom.md (publish command guide). | Documentation |
|
||||
|
||||
## Decisions & Risks
|
||||
- **Overwrite semantics:** Chose version-annotation + supersede-pointer over registry delete. Rationale: OCI delete is not universally supported; additive approach works with all registries. Risk: storage growth from old referrers — mitigated by garbage collection policies on registry side.
|
||||
- **Volatile field list scope:** Conservative initial list (serialNumber, tools, timestamps, creationInfo). Risk: future CycloneDX/SPDX spec versions may add new volatile fields. Mitigation: versioned contract file allows controlled expansion.
|
||||
- **Normalizer placement:** `SbomNormalizer` currently lives in `AirGap.Importer`. For broader use (Scanner, Cli, Attestor), it may need extraction to a shared library. Decision deferred — if multiple modules need it, extract to `StellaOps.Canonical.Sbom` shared lib in a follow-up.
|
||||
- **Media type naming:** Using `application/vnd.stellaops.sbom.cdx+json` and `application/vnd.stellaops.sbom.spdx+json` for published artifacts. Aligns with existing `application/vnd.stellaops.sbom.layer+json` convention.
|
||||
|
||||
## Next Checkpoints
|
||||
- After 041-01 + 041-02: determinism contract established, ready for integration.
|
||||
- After 041-04: OCI publication testable against local registry (distribution/distribution or zot).
|
||||
- After 041-05 + 041-06: full round-trip demo (publish → supersede → resolve → verify).

## Node Hash Recipe
|
||||
|
||||
Node hashes provide content-addressable identifiers for function calls, matching the [Witness V1](witness-v1.md) convention:
|
||||
|
||||
```
|
||||
node_hash = SHA-256(PURL + ":" + normalize(symbol))
|
||||
```
|
||||
|
||||
Where `normalize(symbol)`:
|
||||
1. Demangle C++/Rust symbols
|
||||
2. Strip leading underscores (platform convention)
|
||||
3. Lowercase the result
|
||||
4. Remove whitespace
|
||||
|
||||
### Path Hash Recipe
|
||||
|
||||
```
|
||||
path_hash = SHA-256(entrypoint.node_hash + ":" + sort(calls.map(c => c.node_hash)).join(":"))
|
||||
```
|
||||
|
||||
The path hash is independent of call ordering (sorted) unless `strict_ordering` is true, in which case calls are not sorted before hashing.
|
||||

||||
|
||||
## Coverage Calculation Algorithm
|
||||
|
||||
```
|
||||
total_required = count(paths where optional == false)
|
||||
observed_required = count(paths where optional == false AND has_matching_observation)
|
||||
|
||||
observation_rate = observed_required / total_required
|
||||
= 0.0 if total_required == 0
|
||||
|
||||
verified = observation_rate >= coverage.min_observation_rate
|
||||
```
|
||||
|
||||
For each path, an observation "matches" when:
|
||||
- At least one observation has a `node_hash` matching any call in the path
|
||||
- The observation falls within the time window
|
||||
- The probe type is in the call's `probe_types` list
|
||||
|
||||
---
|
||||
|
||||
## Verification Algorithm
|
||||
|
||||
```
|
||||
VERIFY(predicate, observations, options):
|
||||
1. Filter observations to time window [now - window_seconds, now]
|
||||
2. For each required expected_path:
|
||||
a. For each expected_call in path:
|
||||
- Find observations matching node_hash AND probe_type
|
||||
- Mark call as "observed" if any match found
|
||||
b. Mark path as "covered" if entrypoint OR any call observed
|
||||
3. Compute observation_rate = covered_paths / required_paths
|
||||
4. Collect unexpected = observations not matching any expected call
|
||||
5. Collect missing = required calls with no matching observation
|
||||
6. verified = observation_rate >= min_observation_rate
|
||||
AND (NOT fail_on_unexpected OR unexpected.count == 0)
|
||||
7. Return result with breakdown, unexpected, missing
|
||||
```

### Offline Verification Workflow
|
||||
|
||||
In air-gapped environments:
|
||||
|
||||
1. Export the bundle with function map and observations included
|
||||
2. Transfer to the air-gapped instance
|
||||
3. Run offline verification:
|
||||
```bash
|
||||
stella function-map verify \
|
||||
--function-map ./function-maps/my-service-function-map.json \

## 5. Two-Tier Bundle Modes

|
||||
|
||||
Evidence bundles are exported in one of two modes:
|
||||
|
||||
### 5.1 Light Mode (Default)
|
||||
|
||||
Contains only metadata and attestation envelopes. Binary blobs referenced in `largeBlobs[]` are not embedded.
|
||||
|
||||
```
|
||||
bundle/
|
||||
├── manifest.json # Bundle manifest with exportMode: "light"
|
||||
├── attestations/

│ └── delta-sig.dsse.json
|
||||
└── tsa/
|
||||
├── chain/
|
||||
└── ocsp/
|
||||
```
|
||||
|
||||
**Advantages:** Small size, fast transfer.
|
||||
**Limitation:** Blob replay requires a source (`--blob-source`) or network access.
|
||||
|
||||
### 5.2 Full Mode (`--full`)
|
||||
|
||||
Includes all binary blobs referenced by attestations, enabling fully self-contained offline verification.
|
||||
|
||||
```
|
||||
bundle/
|
||||
├── manifest.json # Bundle manifest with exportMode: "full"

||||
└── ocsp/
|
||||
```
|
||||
|
||||
**Advantages:** Fully self-contained, no network needed for replay.
|
||||
**Limitation:** Larger bundle size.
|
||||
|
||||
## 6. Blob Replay Verification
|
||||
|
||||
When `--replay` is specified, the verifier fetches and checks binary blobs referenced in attestation predicates:
|
||||
|
||||
```bash
|
||||
# Full bundle: blobs are embedded, no external source needed
|
||||
stella bundle verify --bundle full-bundle/ --offline --replay
|
||||
|
||||
# Light bundle: provide local blob source
|
||||
stella bundle verify --bundle light-bundle/ --replay --blob-source /path/to/blobs/
|
||||
|
||||
# Light bundle: fetch from registry (requires network)
|
||||
stella bundle verify --bundle light-bundle/ --replay --blob-source https://registry.example.com/blobs/
|
||||
```
|
||||
|
||||
### 6.1 Replay Steps
|
||||
|
||||
1. Parse attestation envelopes in `attestations/` directory
|
||||
2. Decode DSSE payloads and extract `largeBlobs[]` references
|
||||
3. For each blob reference:
|
||||
- Resolve content from embedded blobs, local source, or registry
|
||||
- Compute digest using declared algorithm (sha256/sha384/sha512)
|
||||
- Compare computed digest against declared digest
|
||||
4. Report pass/fail for each blob
|
||||
|
||||
### 6.2 Offline Constraints
|
||||
|
||||
- In `--offline` mode, registry blob fetches are blocked
|
||||
- Light bundles in offline mode require `--blob-source` pointing to a local directory
|
||||
- Full bundles work in offline mode without additional configuration

Evidence bundles support two export modes to balance transfer speed with auditability:
|
||||
|
||||
| Mode | Export Flag | Contents | Use Case |
|
||||
|------|------------|----------|----------|
|
||||
| **Light** | (default) | Manifest + attestation envelopes + metadata | Quick transfer, metadata-only audit |
|
||||
| **Full** | `--full` | Light + embedded binary blobs in `blobs/` | Air-gap replay, full provenance verification |
|
||||
|
||||
#### 10.6.1 `largeBlobs[]` Field
|
||||
|
||||
The `DeltaSigPredicate` includes a `largeBlobs` array referencing binary artifacts that may be too large to embed in attestation payloads:
|
||||
|
||||
```json
|
||||
{
|
||||
"schemaVersion": "1.0.0",
|
||||
"subject": [...],
|
||||
"delta": [...],
|
||||
"largeBlobs": [
|
||||
{
|
||||
"kind": "binary-patch",
|
||||
"digest": "sha256:a1b2c3...",
|
||||
"mediaType": "application/octet-stream",
|
||||
"sizeBytes": 1048576
|
||||
},
|
||||
{
|
||||
"kind": "sbom-fragment",
|
||||
"digest": "sha256:d4e5f6...",
|
||||
"mediaType": "application/spdx+json",
|
||||
"sizeBytes": 32768
|
||||
}
|
||||
],
|
||||
"sbomDigest": "sha256:789abc..."
|
||||
}
|
||||
```
|
||||
|
||||
**Field Definitions:**
|
||||
|
||||
| Field | Type | Description |
|
||||
|-------|------|-------------|
|
||||
| `largeBlobs[].kind` | string | Blob category: `binary-patch`, `sbom-fragment`, `debug-symbols`, etc. |
|
||||
| `largeBlobs[].digest` | string | Content-addressable digest (`sha256:<hex>`, `sha384:<hex>`, `sha512:<hex>`) |
|
||||
| `largeBlobs[].mediaType` | string | IANA media type of the blob |
|
||||
| `largeBlobs[].sizeBytes` | long | Blob size in bytes |
|
||||
| `sbomDigest` | string | Digest of the canonical SBOM associated with this delta |
|
||||
|
||||
#### 10.6.2 Blob Fetch Strategy
|
||||
|
||||
During `stella bundle verify --replay`, blobs are resolved in priority order:
|
||||
|
||||
1. **Embedded** (full bundles): Read from `blobs/<digest-with-dash>` in bundle directory
|
||||
2. **Local source** (`--blob-source /path/`): Read from specified local directory
|
||||
3. **Registry** (`--blob-source https://...`): HTTP GET from OCI registry (blocked in `--offline` mode)
|
||||
|
||||
#### 10.6.3 Digest Verification
|
||||
|
||||
Fetched blobs are verified against their declared digest using the algorithm prefix:
|
||||
|
||||
```
|
||||
sha256:<hex> → SHA-256
|
||||
sha384:<hex> → SHA-384
|
||||
sha512:<hex> → SHA-512
|
||||
```
|
||||
|
||||
A mismatch fails the blob replay verification step.

**Sprint:** SPRINT_20260122_040_Platform_oci_delta_attestation_pipeline (040-05)
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
stella binary delta-sig attest --predicate <path> --key <path> [options]
|
||||
```
|
||||
|

**Options:**
|
||||
| Option | Alias | Description | Default |
|
||||
|--------|-------|-------------|---------|

||||
| `--rekor-url` | | Rekor transparency log URL for submission | (none) |
|
||||
| `--receipt` | | Path to save Rekor receipt JSON | (none, only with `--rekor-url`) |
|
||||
| `--dry-run` | | Validate predicate and key without signing | `false` |
|
||||
| `--verbose` | `-v` | Show detailed signing and submission steps | `false` |
|
||||
|
||||
**Example:**
|
||||
```bash
|
||||
# Sign predicate and submit to Rekor
|
||||
stella binary delta-sig attest \
|
||||
--predicate delta-sig-predicate.json \
|
||||
--key signing-key.pem \
|
||||
--output signed-envelope.dsse.json \
|
||||
--rekor-url https://rekor.sigstore.dev \
|
||||
--receipt rekor-receipt.json \
|
||||
--verbose
|
||||
|
||||
# Dry run (validate only)
|
||||
stella binary delta-sig attest \
|
||||
--predicate delta-sig-predicate.json \
|
||||
--key signing-key.pem \
|
||||
--dry-run
|
||||
```
|
||||
|
||||
**Signing Behavior:**
|
||||
- Key must be an ECDSA private key (PEM format)
|
||||
- Produces an in-toto v1 statement wrapping the predicate as DSSE payload
|
||||
- PAE (Pre-Authentication Encoding) used per DSSE specification
|
||||
- Signature is Base64-encoded in the envelope
|
||||
|
||||
**Rekor Submission:**
|
||||
- When `--rekor-url` is provided, the signed envelope is submitted to the transparency log
|
||||
- On success, Rekor UUID and log index are displayed
|
||||
- Receipt JSON includes `uuid`, `logIndex`, `integratedTime`, and `logUrl`
|
||||
|
||||
**Exit Codes:**
|
||||
- `0` - Signing (and optional Rekor submission) succeeded
|
||||
- `1` - Signing or submission failed
|
||||
- `2` - Invalid predicate, key format, or configuration error

||||
|
||||
**Sprint:** SPRINT_20260122_040_Platform_oci_delta_attestation_pipeline (040-06)
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
stella bundle verify --bundle <path> [options]
|
||||
```
|
||||
|
||||
**Options:**
|
||||
| Option | Alias | Description | Default |
|
||||
|--------|-------|-------------|---------|
|
||||
| `--bundle` | `-b` | Path to bundle (tar.gz or directory) | (required) |
|
||||
| `--trust-root` | | Path to trusted root certificate (PEM) | (none) |
|
||||
| `--rekor-checkpoint` | | Path to Rekor checkpoint for offline proof verification | (none) |
|
||||
| `--offline` | | Run in offline mode (no network access) | `false` |
|
||||
| `--output` | `-o` | Output format: `table`, `json` | `table` |
|
||||
| `--strict` | | Fail on any warning (missing optional artifacts) | `false` |
|
||||
| `--signer` | | Path to signing key (PEM) for verification report | (none) |
|
||||
| `--signer-cert` | | Path to signer certificate PEM (for report metadata) | (none) |
|
||||
| `--replay` | | Verify binary content by fetching/reading large blobs referenced in attestations | `false` |
|
||||
| `--blob-source` | | Override blob source (registry URL or local directory path) | (auto-detect) |
|
||||
| `--verbose` | `-v` | Show detailed verification steps | `false` |
|
||||
|
||||
**Verification Steps:**
|
||||
1. **Manifest checksum** - Validate bundle manifest integrity
|
||||
2. **Blob digests** - Verify all blob file SHA-256 digests match manifest
|
||||
3. **DSSE signatures** - Validate envelope signatures against trusted keys
|
||||
4. **Rekor proofs** - Verify inclusion proofs against checkpoint (when provided)
|
||||
5. **Timestamps** - Validate RFC 3161 timestamps against TSA certificates
|
||||
6. **Payload types** - Verify predicate types match expectations
|
||||
7. **Blob Replay** (when `--replay`) - Fetch and verify large blobs referenced in attestations
|
||||
|
||||
**Blob Replay Behavior:**
|
||||
- For **full bundles** (blobs embedded): verifies content from `blobs/` directory against attestation digests
|
||||
- For **light bundles** (metadata only): fetches blobs from `--blob-source` (local dir or registry URL)
|
||||
- Supports `sha256`, `sha384`, `sha512` digest algorithms
|
||||
- In `--offline` mode, blob fetch from registries is blocked (only local sources work)
|
||||
|
||||
**Example:**
|
||||
```bash
|
||||
# Basic verification
|
||||
stella bundle verify --bundle evidence-bundle.tar.gz
|
||||
|
||||
# Full verification with replay and trust root

## stella sbom publish — OCI SBOM Publication
|
||||
|
||||
### Synopsis
|
||||
|
||||
```bash
|
||||
stella sbom publish --image <ref> [--file <path>] [--format cdx|spdx] [--overwrite]
|
||||
```
|
||||
|
||||
Publishes a canonical (volatile-fields-stripped, key-sorted) SBOM as an OCI referrer artifact attached to the specified container image. The published artifact is discoverable via the OCI Distribution Spec 1.1 referrers API.
|
||||
|
||||
### Options
|
||||
|
||||
| Option | Alias | Description |
|
||||
|--------|-------|-------------|
|
||||
| `--image <ref>` | `-i` | **Required.** Target image reference (`registry/repo@sha256:...`). Must include digest. |
|
||||
| `--file <path>` | `-f` | Path to SBOM file. If omitted, fetches from Scanner CAS for this image. |
|
||||
| `--format <fmt>` | | SBOM format: `cdx` (CycloneDX) or `spdx`. Auto-detected from file content if omitted. |
|
||||
| `--overwrite` | | Supersede the current active SBOM referrer for this image. |
|
||||
| `--registry-url <url>` | | Override registry URL (defaults to parsed from `--image`). |
|
||||
| `--verbose` | | Show detailed output including blob digest and normalization info. |
|
||||
|
||||
### Behavior
|
||||
|
||||
1. **Normalization**: The SBOM is canonicalized before publication:
|
||||
- Volatile fields stripped: `serialNumber`, `metadata.tools`, `metadata.authors`, `metadata.timestamp` (CycloneDX); `creationInfo.created`, `creationInfo.creators`, `creationInfo.licenseListVersion` (SPDX).
|
||||
- Object keys sorted lexicographically (ordinal).
|
||||
- Arrays of objects sorted by deterministic keys (bom-ref, purl, name@version).
|
||||
- See `docs/contracts/sbom-volatile-fields.json` for the authoritative field list.
|
||||
|
||||
2. **Publication**: The canonical SBOM bytes are pushed as an OCI artifact with:
|
||||
- `artifactType`: `application/vnd.stellaops.sbom.cdx+json` or `application/vnd.stellaops.sbom.spdx+json`
|
||||
- `subject`: points to the image manifest digest
|
||||
- Annotations: `dev.stellaops/sbom-version`, `dev.stellaops/sbom-format`
|
||||
|
||||
3. **Overwrite/Supersede**: When `--overwrite` is specified:
|
||||
- The current active SBOM referrer is resolved (highest version number).
|
||||
- A new referrer is pushed with `version = prior + 1` and a `dev.stellaops/sbom-supersedes` annotation pointing to the prior manifest digest.
|
||||
- No registry deletes are performed (purely additive).
|
||||
|
||||
### Exit Codes
|
||||
|
||||
| Code | Meaning |
|
||||
|------|---------|
|
||||
| 0 | Publication succeeded |
|
||||
| 1 | Publication failed (registry error, auth failure) |
|
||||
| 2 | Error (file not found, invalid image reference, parse error) |
|
||||
|
||||
### Examples

||||
|
||||

|
||||
# Publish a CycloneDX SBOM to an image
|
||||
stella sbom publish --image registry.example.com/myapp@sha256:abc123... --file app.cdx.json

||||
# Verbose output
|
||||

|
||||
```
|
||||
|
||||
### Sample Output
|
||||
|
||||
```

# Delta Attestation Workflow Guide
|
||||
|
||||
> **Audience:** CI/CD engineers, release operators, security auditors
|
||||
>
|
||||
> **Purpose:** End-to-end guide for generating, signing, attaching, verifying, and exporting delta-sig attestations.
|
||||
>
|
||||
> **Sprint:** SPRINT_20260122_040_Platform_oci_delta_attestation_pipeline
|
||||
|
||||
## Overview
|
||||
|
||||
The delta attestation workflow provides verifiable evidence of binary-level changes between releases. It covers the full lifecycle from generating a delta-sig predicate through to offline bundle verification.
|
||||
|
||||
```
|
||||
diff → attest → attach → verify → export → offline-verify
|
||||
```
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- `stella` CLI installed and configured
|
||||
- EC signing key (PEM format) for attestation signing
|
||||
- Access to target OCI registry (for attach/verify)
|
||||
- (Optional) Rekor transparency log URL for public verifiability
|
||||
|
||||
## Step 1: Generate Delta-Sig Predicate
|
||||
|
||||
Compare two binary builds to produce a delta-sig predicate describing function-level changes:
|
||||
|
||||
```bash
|
||||
stella binary delta-sig diff \
|
||||
--old /path/to/old-binary \
|
||||
--new /path/to/new-binary \
|
||||
--output delta-predicate.json \
|
||||
--arch linux-amd64
|
||||
```
|
||||
|
||||
The predicate JSON follows the `https://stellaops.dev/delta-sig/v1` schema and includes:
|
||||
- `subject[]` - Old and new binary references with digests
|
||||
- `delta[]` - Function-level changes (added, removed, modified)
|
||||
- `summary` - Aggregate change statistics
|
||||
- `tooling` - Lifter and diff algorithm metadata
|
||||
- `largeBlobs[]` - References to binary patches or SBOM fragments (optional)
|
||||
- `sbomDigest` - Digest of the associated canonical SBOM (optional)
|
||||
|
||||
## Step 2: Sign and Attest
|
||||
|
||||
Sign the predicate with an EC key, producing a DSSE envelope. Optionally submit to a Rekor transparency log:
|
||||
|
||||
```bash
|
||||
stella binary delta-sig attest \
|
||||
--predicate delta-predicate.json \
|
||||
--key signing-key.pem \
|
||||
--output signed-envelope.dsse.json \
|
||||
--rekor-url https://rekor.sigstore.dev \
|
||||
--receipt rekor-receipt.json \
|
||||
--verbose
|
||||
```
|
||||
|
||||
**Output:**
|
||||
- `signed-envelope.dsse.json` - DSSE envelope with in-toto v1 statement
|
||||
- `rekor-receipt.json` - Rekor inclusion proof (UUID, log index, integrated time)
|
||||
|
||||
**Without Rekor (air-gapped environments):**
|
||||
|
||||
```bash
|
||||
stella binary delta-sig attest \
|
||||
--predicate delta-predicate.json \
|
||||
--key signing-key.pem \
|
||||
--output signed-envelope.dsse.json
|
||||
```
|
||||
|
||||
## Step 3: Attach to OCI Image
|
||||
|
||||
Attach the signed attestation to the target OCI image via ORAS referrers:
|
||||
|
||||
```bash
|
||||
stella attest attach \
|
||||
--image registry.example.com/app:v1.2 \
|
||||
--attestation signed-envelope.dsse.json \
|
||||
--verbose
|
||||
```
|
||||
|
||||
The attestation is stored as a referrer artifact in the registry, discoverable by image digest.
|
||||
|
||||
## Step 4: Verify Attestations
|
||||
|
||||
Verify that attestations are properly attached and valid:
|
||||
|
||||
```bash
|
||||
stella attest verify \
|
||||
--image registry.example.com/app:v1.2 \
|
||||
--predicate-type "https://stellaops.dev/delta-sig/v1" \
|
||||
--require-rekor \
|
||||
--verbose
|
||||
```
|
||||
|
||||
This checks:
|
||||
- DSSE envelope signature validity
|
||||
- Predicate type matches expected schema
|
||||
- Rekor annotations are present and valid (when `--require-rekor`)
|
||||
|
||||
## Step 5: Export Evidence Bundle
|
||||
|
||||
Export all attestation evidence for offline environments:
|
||||
|
||||
```bash
|
||||
# Light mode (metadata only, small size)
|
||||
stella evidence export-bundle \
|
||||
--image registry.example.com/app:v1.2 \
|
||||
--output evidence-light.tar.gz
|
||||
|
||||
# Full mode (includes binary blobs for replay)
|
||||
stella evidence export-bundle \
|
||||
--image registry.example.com/app:v1.2 \
|
||||
--output evidence-full.tar.gz \
|
||||
--full
|
||||
```
|
||||
|
||||
### Bundle Contents
|
||||
|
||||
**Light bundle:**
|
||||
```
|
||||
bundle/
|
||||
├── manifest.json # exportMode: "light"
|
||||
└── attestations/
|
||||
└── delta-sig.dsse.json
|
||||
```
|
||||
|
||||
**Full bundle:**
|
||||
```
|
||||
bundle/
|
||||
├── manifest.json # exportMode: "full"
|
||||
├── attestations/
|
||||
│ └── delta-sig.dsse.json
|
||||
└── blobs/
|
||||
├── sha256-<hex1> # Binary patch
|
||||
└── sha256-<hex2> # SBOM fragment
|
||||
```
|
||||
|
||||
## Step 6: Offline Bundle Verification
|
||||
|
||||
Verify the exported bundle in air-gapped environments:
|
||||
|
||||
```bash
|
||||
# Full bundle: self-contained verification with blob replay
|
||||
stella bundle verify \
|
||||
--bundle evidence-full.tar.gz \
|
||||
--offline \
|
||||
--trust-root /etc/stellaops/tsa-root.pem \
|
||||
--replay \
|
||||
--verbose
|
||||
|
||||
# Light bundle: provide local blob source for replay
|
||||
stella bundle verify \
|
||||
--bundle evidence-light.tar.gz \
|
||||
--offline \
|
||||
--replay \
|
||||
--blob-source /path/to/cached-blobs/
|
||||
```
|
||||
|
||||
### Verification Steps

|
||||
| `DSSE signature ✗` | Key mismatch | Verify signing key matches trusted keys |
|
||||
| `Rekor proof ✗` | No checkpoint provided | Add `--rekor-checkpoint` for offline |
|
||||
| Exit code 2 | Invalid predicate JSON | Check required fields: subject, delta, summary, tooling, computedAt |

### 13.3 · Gate-to-Rego Translation
|
||||
|
||||
Each C# gate type maps to a Rego deny rule pattern:
|
||||
|
||||
| Gate Type | Rego Pattern | Remediation Code |
|
||||
|-----------|-------------|-----------------|
|
||||
| `CvssThresholdGate` | `input.cvss.score >= threshold` | `CVSS_EXCEED` |
|
||||
| `SignatureRequiredGate` | `not input.dsse.verified` | `SIG_MISS` |
|
||||
| `EvidenceFreshnessGate` | `not input.freshness.tstVerified` | `FRESH_EXPIRED` |
|
||||
| `SbomPresenceGate` | `not input.sbom.canonicalDigest` | `SBOM_MISS` |
|
||||
| `MinimumConfidenceGate` | `input.confidence < threshold` | `CONF_LOW` |
|
||||
| `UnknownsBudgetGate` | `input.unknownsRatio > threshold` | `UNK_EXCEED` |
|
||||
| `ReachabilityRequirementGate` | `not input.reachability.status` | `REACH_REQUIRED` |
|
||||
|
||||
### 13.4 · Remediation Hints
|
||||
|
||||
When a gate blocks, the system resolves structured remediation hints:
|
||||
|
||||
```
|
||||
Priority: Gate-defined hint > Built-in defaults > null
|

```
|
||||
|
||||
Placeholders (`{purl}`, `{image}`, `{reason}`) are resolved via `RemediationContext` at evaluation time.
|
||||
|
||||
### 13.5 · Determinism
|
||||
|
||||
All exports and evaluations are deterministic:
|
||||
- Same policy + same input = same output (hash-verifiable)
|
||||
- Exports include SHA-256 `digest` field
|
||||
- No time-dependent logic in deterministic mode
|
||||
- `outputDigest` in evaluation results enables replay verification

# Policy Import/Export Guide
|
||||
|
||||
This guide covers bidirectional policy exchange between Stella's native C# engine and OPA/Rego.
|
||||
|
||||
## Overview
|
||||
|
||||
Stella supports two policy formats:
|
||||
- **PolicyPack v2 (JSON)**: Canonical format with typed gates, environment overrides, and remediation hints.
|
||||
- **OPA/Rego**: Standard policy-as-code format for interoperability with OPA-based toolchains.
|
||||
|
||||
The C# gate engine remains primary. Rego is an export target for teams using OPA, and an import source for adopting external policies.
|
||||
|
||||
## Formats
|
||||
|
||||
### PolicyPack v2 (JSON)
|
||||
|
||||
Schema: `policy.stellaops.io/v2`
|
||||
|
||||
Structure:
|
||||
```json
|
||||
{
|
||||
"apiVersion": "policy.stellaops.io/v2",
|
||||
"kind": "PolicyPack",
|
||||
"metadata": { "name": "...", "version": "1.0.0" },
|
||||
"spec": {
|
||||
"settings": { "defaultAction": "block", "deterministicMode": true },
|
||||
"gates": [...],
|
||||
"rules": [...]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Key features:
|
||||
- Per-environment configuration overrides (production/staging/development thresholds)
|
||||
- Structured remediation hints with CLI command templates
|
||||
- Deterministic evaluation mode
|
||||
- SHA-256 content digest for integrity
|
||||
|
||||
### OPA/Rego
|
||||
|
||||
Generated or imported Rego follows the deny-by-default pattern:
|
||||
|
||||
```rego
|
||||
package stella.release
|
||||
|
||||
import rego.v1
|
||||
|
||||
default allow := false
|
||||
|
||||
deny contains msg if {
|
||||
not input.dsse.verified
|
||||
msg := "DSSE signature missing"
|
||||
}
|
||||
|
||||
allow if { count(deny) == 0 }
|
||||
|
||||
remediation contains hint if {
|
||||
some msg in deny
|
||||
msg == "DSSE signature missing"
|
||||
hint := {"code": "DSSE_MISS", "fix": "...", "severity": "critical"}
|
||||
}
|
||||
```
|
||||
|
||||
## CLI Commands
|
||||
|
||||
### Export
|
||||
|
||||
Export a policy to JSON or Rego:
|
||||
|
||||
```bash
|
||||
# Export to Rego
|
||||
stella policy export --file policy.json --format rego --output-file release.rego
|
||||
|
||||
# Export with environment-specific thresholds
|
||||
stella policy export --file policy.json --format rego --environment production
|
||||
|
||||
# Export without remediation hints
|
||||
stella policy export --file policy.json --format json --include-remediation false
|
||||
|
||||
# Export to stdout (pipe-friendly)
|
||||
stella policy export --file policy.json --format rego | opa check -
|
||||
```
|
||||
|
||||
### Import
|
||||
|
||||
Import a policy from JSON or Rego:
|
||||
|
||||
```bash
|
||||
# Import and validate a JSON policy
|
||||
stella policy import --file production-baseline.json
|
||||
|
||||
# Import with validation only (no persist)
|
||||
stella policy import --file external-policy.rego --validate-only
|
||||
|
||||
# Dry-run to preview changes
|
||||
stella policy import --file new-rules.json --dry-run
|
||||
|
||||
# Force format detection
|
||||
stella policy import --file rules.txt --format rego
|
||||
```
|
||||
|
||||
### Validate
|
||||
|
||||
Validate a policy file:
|
||||
|
||||
```bash
|
||||
# Basic validation
|
||||
stella policy validate --file policy.json
|
||||
|
||||
# Strict mode (warnings become errors)
|
||||
stella policy validate --file policy.json --strict
|
||||
|
||||
# JSON output for CI integration
|
||||
stella policy validate --file policy.json --output json
|
||||
```
|
||||
|
||||
Exit codes: `0` = valid, `1` = warnings, `2` = errors.
|
||||
|
||||
### Evaluate
|
||||
|
||||
Evaluate a policy against evidence:
|
||||
|
||||
```bash
|
||||
# Evaluate with table output
|
||||
stella policy evaluate --policy baseline.json --input evidence.json
|
||||
|
||||
# With environment override
|
||||
stella policy evaluate --policy baseline.json --input evidence.json --environment staging
|
||||
|
||||
# JSON output for programmatic use
|
||||
stella policy evaluate --policy baseline.json --input evidence.json --output json
|
||||
|
||||
# CI mode (GitHub Actions annotations)
|
||||
stella policy evaluate --policy baseline.json --input evidence.json --output ci
|
||||
```
|
||||
|
||||
Exit codes: `0` = allow, `1` = warn, `2` = block.
|
||||
|
||||
## Evidence Input Format
|
||||
|
||||
The evaluation input follows the canonical evidence JSON schema:
|
||||
|
||||
```json
|
||||
{
|
||||
"environment": "production",
|
||||
"subject": {
|
||||
"imageDigest": "sha256:abc...",
|
||||
"purl": "pkg:docker/myapp@1.0.0",
|
||||
"tags": ["env:prod"]
|
||||
},
|
||||
"dsse": { "verified": true, "signers": ["ca://fulcio/..."] },
|
||||
"rekor": { "verified": true, "logID": "...", "integratedTime": 1737480000 },
|
||||
"sbom": { "format": "cyclonedx-1.6", "canonicalDigest": "sha256:..." },
|
||||
"freshness": { "tstVerified": true, "timestamp": "2026-01-22T10:00:00Z", "maxAgeHours": 24 },
|
||||
"cvss": { "score": 7.5, "version": "3.1" },
|
||||
"reachability": { "status": "confirmed", "confidence": 0.85 },
|
||||
"confidence": 0.82
|
||||
}
|
||||
```
|
||||
|
||||
## Remediation Hints
|
||||
|
||||
When a gate blocks, the CLI displays actionable fix suggestions:
|
||||
|
||||
```
|
||||
Decision: BLOCK
|
||||
|
||||
Gate Type Result Reason
|
||||
signature SignatureRequiredGate FAIL Required signature missing
|
||||
sbom SbomPresenceGate PASS passed
|
||||
|
||||
Remediation:
|
||||
SIG_MISS: Required signature missing
|
||||
- Sign attestation with DSSE.
|
||||
$ stella attest attach --sign --image sha256:abc...
|
||||
- Anchor attestation in Rekor.
|
||||
$ stella attest attach --rekor --image sha256:abc...
|
||||
```
|
||||
|
||||
## Rego Import Behavior
|
||||
|
||||
When importing Rego files, the system:
|
||||
1. Parses `deny` rules and maps known patterns to native gates (CVSS comparisons, boolean checks).
|
||||
2. Extracts `remediation` rules into structured hints.
|
||||
3. Unknown patterns are preserved and evaluated via the embedded OPA evaluator.
|
||||
4. Validation reports which rules mapped natively vs. remain OPA-evaluated.
|
||||
|
||||
## Determinism
|
||||
|
||||
All evaluations are deterministic:
|
||||
- Same policy + same input = same output (hash-verifiable)
|
||||
- No time-dependent logic in deterministic mode
|
||||
- `outputDigest` in evaluation results enables replay verification
|
||||
|
||||

# Runtime Linkage Verification Guide
|
||||
|
||||
> **Ownership:** Scanner Guild / Signals Guild
|
||||
> **Services:** `StellaOps.Scanner.Reachability.FunctionMap`
|
||||
> **API:** `POST /api/v1/function-maps`, `POST /api/v1/function-maps/{id}/verify`
|
||||
> **CLI:** `stella function-map generate|verify`, `stella observations query`
|
||||
|
||||
## What is Runtime Linkage Verification?
|
||||
|
||||
Runtime linkage verification bridges the gap between **static analysis** (what code _could_ run) and **runtime observation** (what code _actually_ runs). It works by:
|
||||
|
||||
1. **Generating a function map** from static analysis (SBOM + call graph) that declares expected call paths
|
||||
2. **Deploying probes** (eBPF uprobes/kprobes) to observe actual function invocations at runtime
|
||||
3. **Verifying** that observed call patterns match the expected static model
|
||||
|
||||
This produces a confidence metric (observation rate) quantifying how much of the declared attack surface has been confirmed by runtime evidence.
|
||||
|
||||
---
|
||||
|
||||
## When to Use Function Maps
|
||||
|
||||
| Scenario | Benefit |
|
||||
|----------|---------|
|
||||
| **High-risk vulnerabilities** | Confirm whether vulnerable code paths are actually exercised |
|
||||
| **Reachability disputes** | Resolve static "maybe reachable" findings with runtime evidence |
|
||||
| **Compliance audits** | Provide cryptographic proof of runtime behavior |
|
||||
| **Air-gapped environments** | Bundle function maps and observations for offline verification |
|
||||
| **Continuous monitoring** | Track coverage drift over deployment lifecycle |
|
||||
|
||||
---
|
||||
|
||||
## Step-by-Step Guide
|
||||
|
||||
### 1. Generate a Function Map
|
||||
|
||||
Create a function map predicate from your SBOM and optional static analysis:
|
||||
|
||||
```bash
|
||||
stella function-map generate \
|
||||
--sbom ./app.cdx.json \
|
||||
--service my-backend \
|
||||
--hot-functions "crypto/*" --hot-functions "auth/*" \
|
||||
--min-rate 0.95 \
|
||||
--window 1800 \
|
||||
--output function-map.json
|
||||
```
|
||||
|
||||
**Key options:**
|
||||
- `--hot-functions`: Glob patterns for functions of interest (crypto, auth, network are common)
|
||||
- `--min-rate`: Minimum observation rate to consider "verified" (default 0.95 = 95%)
|
||||
- `--window`: Observation window in seconds (default 1800 = 30 minutes)
|
||||
- `--static-analysis`: Path to static analysis results for richer call paths
|
||||
|
||||
The output is a JSON predicate conforming to `https://stella.ops/predicates/function-map/v1`.
|
||||
|
||||
### 2. Deploy Probes
|
||||
|
||||
Configure the Stella runtime agent to attach probes for the functions declared in your map. The agent uses eBPF to observe function calls without modifying application code.
|
||||
|
||||
Supported probe types:
|
||||
- `uprobe` / `uretprobe` — User-space function entry/exit
|
||||
- `kprobe` / `kretprobe` — Kernel function entry/exit
|
||||
- `tracepoint` — Kernel tracepoints
|
||||
- `usdt` — User-space statically defined tracing
|
||||
|
||||
The runtime agent writes observations in NDJSON format with fields:
|
||||
- `node_hash` — SHA-256(PURL + normalized symbol)
|
||||
- `function_name` — Observed function symbol
|
||||
- `probe_type` — How it was observed
|
||||
- `observed_at` — Timestamp
|
||||
- `container_id`, `pod_name`, `namespace` — Context
|
||||
|
||||
### 3. Verify Observations Against the Map
|
||||
|
||||
After accumulating observations, verify coverage:
|
||||
|
||||
```bash
|
||||
stella function-map verify \
|
||||
--function-map function-map.json \
|
||||
--from "2026-01-23T00:00:00Z" \
|
||||
--to "2026-01-23T01:00:00Z" \
|
||||
--format table
|
||||
```
|
||||
|
||||
For offline verification with a bundled observations file:
|
||||
|
||||
```bash
|
||||
stella function-map verify \
|
||||
--function-map function-map.json \
|
||||
--offline \
|
||||
--observations observations.ndjson \
|
||||
--format json
|
||||
```
|
||||
|
||||
**Output includes:**
|
||||
- `verified`: Whether observation rate meets the threshold
|
||||
- `observation_rate`: Fraction of expected paths confirmed (0.0-1.0)
|
||||
- `target_rate`: Required rate from the function map
|
||||
- `per_path_breakdown`: Status of each declared call path
|
||||
- `unexpected_symbols`: Functions observed but not in the map
|
||||
- `missing_symbols`: Expected functions not yet observed
|
||||
|
||||
### 4. Upload to Platform (Optional)
|
||||
|
||||
Store function maps in the Platform for centralized management:
|
||||
|
||||
```bash
|
||||
# Create via API
|
||||
curl -X POST /api/v1/function-maps \
|
||||
-H "Content-Type: application/json" \
|
||||
-d @function-map.json
|
||||
|
||||
# Verify via API
|
||||
curl -X POST /api/v1/function-maps/{id}/verify \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"observations": [...]}'
|
||||
|
||||
# Check coverage dashboard
|
||||
curl GET /api/v1/function-maps/{id}/coverage
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Predicate Schema
|
||||
|
||||
Function maps use the in-toto attestation framework with predicate type:
|
||||
|
||||
```
|
||||
https://stella.ops/predicates/function-map/v1
|
||||
```
|
||||
|
||||
See [Function Map V1 Contract](../../../contracts/function-map-v1.md) for the full schema specification.
|
||||
|
||||
---
|
||||
|
||||
## Integration with Air-Gap Bundles
|
||||
|
||||
Function maps, observations, and verification reports can be included in offline bundles:
|
||||
|
||||
```
|
||||
bundle.stella.bundle.tgz
|
||||
├── function-maps/
|
||||
│ ├── {service}-function-map.json
|
||||
│ └── {service}-function-map.dsse.json
|
||||
├── observations/
|
||||
│ └── {date-label}-observations.ndjson
|
||||
└── verification/
|
||||
├── verification-report.json
|
||||
└── verification-report.dsse.json
|
||||
```
|
||||
|
||||
See [Offline Bundle Format](../../airgap/guides/offline-bundle-format.md) for artifact type details.
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Low Observation Rate
|
||||
|
||||
**Symptom:** Verification reports `observation_rate < target_rate`.
|
||||
|
||||
**Causes:**
|
||||
- Observation window too short — increase `--window` or widen `--from`/`--to`
|
||||
- Probes not attached — check runtime agent logs for attachment failures
|
||||
- Application hasn't exercised the code paths — generate representative load
|
||||
- Binary stripped or ASLR — provide `--binary-path` hints in the function map
|
||||
|
||||
**Resolution:**
|
||||
1. Use `stella observations query --summary` to see what's been collected
|
||||
2. Check per-path breakdown for which specific paths are unobserved
|
||||
3. Extend the observation window or trigger relevant application behavior
|
||||
|
||||
### Unexpected Symbols
|
||||
|
||||
**Symptom:** Verification reports unexpected function calls not in the map.
|
||||
|
||||
**Causes:**
|
||||
- Dynamic dispatch or reflection invoking functions not in static analysis
|
||||
- Shared libraries loaded at runtime that weren't in the SBOM
|
||||
- Hot functions pattern too narrow
|
||||
|
||||
**Resolution:**
|
||||
1. Regenerate the function map with broader `--hot-functions` patterns
|
||||
2. Add the unexpected symbols as optional paths if they're benign
|
||||
3. Set `--fail-on-unexpected false` if unexpected calls should be informational only
|
||||
|
||||
### Node Hash Mismatch
|
||||
|
||||
**Symptom:** Observations exist but don't match expected node hashes.
|
||||
|
||||
**Causes:**
|
||||
- PURL mismatch between SBOM and runtime (version drift)
|
||||
- Symbol name normalization differences (C++ mangling, etc.)
|
||||
|
||||
**Resolution:**
|
||||
1. Verify the PURL in observations matches the function map subject
|
||||
2. Check that symbol names are normalized consistently (same demangling rules)
|
||||
3. Regenerate the function map with the current deployed SBOM version

|

## Overview
|
||||
|
||||
The Unified Trust Score is a facade over existing EWS (Evidence-Weighted Score) and Determinization systems. It provides a single API for computing risk scores, uncertainty metrics, and score replay proofs without replacing any underlying scoring logic.
|
||||
|
||||
---
|
||||
|
||||
## How It Works
|
||||
|
||||
1. **Input** — Caller provides signal values (reachability, runtime, exploit, etc.) and optional context (CVE ID, PURL, SBOM ref)
|
||||
2. **EWS computation** — The facade delegates to `IEvidenceWeightedScoreCalculator` using weights from a versioned manifest
|
||||
3. **Entropy calculation** — `IUncertaintyScoreCalculator` computes the unknowns fraction (U) from signal presence/absence
|
||||
4. **Conflict detection** — `IConflictDetector` identifies contradictory signals
|
||||
5. **Delta calculation** — For missing signals, computes potential score impact ranges
|
||||
6. **Result assembly** — Returns `UnifiedScoreResult` combining all outputs
|
||||
|
||||
---
|
||||
|
||||
## The Unknowns Fraction (U)
|
||||
|
||||
The `UnknownsFraction` exposes how much of the score depends on absent data:
|
||||
|
||||
```
|
||||
U = 1 - (weighted_present_signals / total_weight)
|
||||
```
|
||||
|
||||
### Unknowns Bands
|
||||
|
||||
| U Range | Band | Meaning | Recommended Action |
|
||||
|---------|------|---------|-------------------|
|
||||
| 0.0 – 0.2 | **Complete** | All signals present | Automated decisions safe |
|
||||
| 0.2 – 0.4 | **Adequate** | Sufficient signal coverage | Automated decisions safe |
|
||||
| 0.4 – 0.6 | **Sparse** | Signal gaps exist | Manual review recommended |
|
||||
| 0.6 – 1.0 | **Insufficient** | Critical data missing | Block until more signals arrive |
|
||||
|
||||
Band thresholds align with Determinization configuration:
|
||||
- `RefreshEntropyThreshold: 0.40` — triggers signal refresh attempt
|
||||
- `ManualReviewEntropyThreshold: 0.60` — requires human review
|
||||
|
||||
---
|
||||
|
||||
## Delta-If-Present
|
||||
|
||||
When signals are absent, the facade calculates how the score would change if each missing signal were provided:
|
||||
|
||||
```json
|
||||
{
|
||||
"signal": "reachability",
|
||||
"min_impact": -15,
|
||||
"max_impact": 8,
|
||||
"weight": 0.30,
|
||||
"description": "If reachability confirmed as not-reachable, score decreases by up to 15"
|
||||
}
|
||||
```
|
||||
|
||||
This helps operators prioritize which signals to gather first.
|
||||
|
||||
---
|
||||
|
||||
## Weight Manifests
|
||||
|
||||
EWS weights are stored in versioned JSON files under `etc/weights/`:
|
||||
|
||||
```
|
||||
etc/weights/v2026-01-22.weights.json
|
||||
```
|
||||
|
||||
Manifests are:
|
||||
- **Immutable** once published
|
||||
- **Content-addressed** via SHA-256 hash
|
||||
- **Pinnable** by policy rules via `weights_ref`
|
||||
- **Auditable** — the manifest version and hash are included in every score result
|
||||
|
||||
See [Scoring Algebra §4](../../technical/scoring-algebra.md) for the manifest schema.

|
||||
stella gate score weights diff v2026-01-22 v2026-02-01
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Score Replay and Verification
|
||||
|
||||
Every computed score can produce a **replay proof** — a DSSE-signed attestation (payload type `application/vnd.stella.score+json`) that records:
|
||||
|
||||
1. Canonical input hashes (SBOM, VEX, etc.)
|
||||
2. Transform versions applied (canonicalization, normalization, decay)
|
||||
3. Step-by-step algebra decisions (signal × weight = contribution)
|
||||
4. Final score and metadata
|
||||
|
||||
Replay proofs enable:
|
||||
- **Independent verification** — auditors re-execute the computation
|
||||
- **Transparency logging** — optional anchoring to Rekor for non-repudiation
|
||||
- **OCI storage** — proofs stored as OCI referrers ("StellaBundle" pattern)
|
||||

||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### High Unknowns Fraction (U > 0.6)
|
||||
|
||||
**Symptom:** Score shows "Insufficient" band, decisions are blocked.
|
||||
|
||||
**Causes:**
|
||||
- Missing reachability analysis (run `stella scan` with `--reachability`)
|
||||
- No VEX data available (check VEX feed configuration)
|
||||
- Runtime observations not collected (configure runtime agent)
|
||||
|
||||
**Resolution:**
|
||||
1. Run `stella score explain <finding-id>` to see which signals are missing
|
||||
2. Use `--show-deltas` to understand which signals would have the most impact
|
||||
3. Prioritize gathering signals with the highest weight × delta
|
||||
|
||||
### Score Disagrees with CVSS
|
||||
|
||||
**Symptom:** EWS score is much lower than expected from CVSS alone.
|
||||
|
||||
**Explanation:** EWS incorporates reachability, runtime, backport, and mitigation signals that CVSS does not. A high-CVSS vulnerability that is not reachable or already mitigated will have a lower EWS score.
|
||||
|
||||
**Resolution:** Run `stella score explain` to see the per-dimension breakdown and understand which signals are reducing the score.
|
||||
|
||||
### Replay Verification Fails
|
||||
|
||||
**Symptom:** `stella score verify` reports `score_matches: false`.
|
||||
|
||||
**Causes:**
|
||||
- Weight manifest version changed between compute and verify
|
||||
- Signal inputs were modified after scoring
|
||||
- Non-determinism in signal providers (check for time-dependent signals)
|
||||
|
||||
**Resolution:**
|
||||
1. Pin the weight manifest version in the verify request
|
||||
2. Ensure canonical inputs match (compare SHA-256 hashes)
|
||||
3. Check the `differences` field in the verify response for specific mismatches

## 17) Offline Witness Verification
|
||||
|
||||
> **Sprint:** SPRINT_20260122_038_Scanner_ebpf_probe_type (EBPF-004)
|
||||
|
||||
This section documents the deterministic replay verification algorithm for runtime witnesses, enabling air-gapped environments to independently verify witness attestations.
|
||||
|
||||
### 17.1 Input Canonicalization (RFC 8785 JCS)
|
||||
|
||||
All witness payloads MUST be canonicalized before hashing or signing using **JSON Canonicalization Scheme (JCS)** per RFC 8785:
|
||||
|
||||
1. **Property ordering**: Object properties are sorted lexicographically by key name (Unicode code point order).
|
||||
2. **Number serialization**: Numbers are serialized without unnecessary precision; integers as integers, decimals with minimal representation.
|
||||
3. **String encoding**: UTF-8 with no BOM; escape sequences normalized to `\uXXXX` form for control characters.
|
||||
4. **Whitespace**: No insignificant whitespace between tokens.
|
||||
5. **Null handling**: Explicit `null` values are preserved; absent keys are omitted.
|
||||
|
||||
**Canonicalization algorithm:**
|
||||
|
||||
```
|
||||
function canonicalize(json_object):
|
||||
if json_object is null:
|
||||
return "null"
|
||||
if json_object is boolean:
|
||||
return "true" | "false"
|
||||
if json_object is number:
|
||||
return serialize_number(json_object) # RFC 8785 §3.2.2.3
|
||||
if json_object is string:
|
||||
return quote(escape(json_object))
|
||||
if json_object is array:
|
||||
return "[" + join(",", [canonicalize(elem) for elem in json_object]) + "]"
|
||||
if json_object is object:
|
||||
keys = sorted(json_object.keys(), key=unicode_codepoint_order)
|
||||
pairs = [quote(key) + ":" + canonicalize(json_object[key]) for key in keys]
|
||||
return "{" + join(",", pairs) + "}"
|
||||
```
|
||||
|
||||
### 17.2 Observation Ordering Rules
|
||||
|
||||
When a witness contains multiple observations (e.g., from eBPF probes), they MUST be ordered deterministically before hashing:
|
||||
|
||||
1. **Primary sort**: By `observedAt` timestamp (UTC, ascending)
|
||||
2. **Secondary sort**: By `nodeHash` (lexicographic ascending)
|
||||
3. **Tertiary sort**: By `observationId` (lexicographic ascending, for tie-breaking)
|
||||
|
||||
**Observation hash computation:**
|
||||
|
||||
```
|
||||
function compute_observations_hash(observations):
|
||||
sorted_observations = sort(observations,
|
||||
key=lambda o: (o.observedAt, o.nodeHash, o.observationId))
|
||||
|
||||
canonical_array = []
|
||||
for obs in sorted_observations:
|
||||
canonical_array.append({
|
||||
"observedAt": obs.observedAt.toISOString(),
|
||||
"nodeHash": obs.nodeHash,
|
||||
"functionName": obs.functionName,
|
||||
"probeType": obs.probeType, # EBPF-001: kprobe|uprobe|tracepoint|usdt|fentry|fexit
|
||||
"containerHash": sha256(obs.containerId + obs.podName + obs.namespace)
|
||||
})
|
||||
|
||||
return sha256(canonicalize(canonical_array))
|
||||
```
|
||||
|
||||
### 17.3 Signature Verification Sequence
|
||||
|
||||
Offline verification MUST follow this exact sequence to ensure deterministic results:
|
||||
|
||||
1. **Parse DSSE envelope**: Extract `payloadType`, `payload` (base64-decoded), and `signatures[]`.
|
||||
|
||||
2. **Verify payload hash**:
|
||||
```
|
||||
expected_hash = sha256(payload_bytes)
|
||||
assert envelope.payload_sha256 == expected_hash
|
||||
```
|
||||
|
||||
3. **Verify DSSE signature(s)**: For each signature in `signatures[]`:
|
||||
```
|
||||
pae_string = "DSSEv1 " + len(payloadType) + " " + payloadType + " " + len(payload) + " " + payload
|
||||
verify_signature(signature.sig, pae_string, get_public_key(signature.keyid))
|
||||
```
|
||||
|
||||
4. **Verify Rekor inclusion** (if present):
|
||||
```
|
||||
fetch_or_load_checkpoint(rekor_log_id)
|
||||
verify_merkle_inclusion(entry_hash, inclusion_proof, checkpoint.root_hash)
|
||||
verify_checkpoint_signature(checkpoint, rekor_public_key)
|
||||
```
|
||||
|
||||
5. **Verify timestamp** (if RFC 3161 TST present):
|
||||
```
|
||||
verify_tst_signature(tst, tsa_certificate)
|
||||
assert tst.timestamp <= now() + allowed_skew
|
||||
```
|
||||
|
||||
6. **Verify witness content**:
|
||||
```
|
||||
witness = parse_json(payload)
|
||||
recomputed_observations_hash = compute_observations_hash(witness.observations)
|
||||
assert witness.observationsDigest == recomputed_observations_hash
|
||||
```
|
||||
|
||||
### 17.4 Offline Bundle Structure Requirements
|
||||
|
||||
A StellaBundle for offline witness verification MUST include:
|
||||
|
||||
```
|
||||
bundle/
|
||||
├── manifest.json # Bundle manifest v2.0.0
|
||||
├── witnesses/
|
||||
│ └── <claim_id>.witness.dsse.json # DSSE-signed witness
|
||||
├── proofs/
|
||||
│ ├── rekor-inclusion.json # Rekor inclusion proof
|
||||
│ ├── checkpoint.json # Rekor checkpoint (signed)
|
||||
│ └── rfc3161-tst.der # Optional RFC 3161 timestamp
|
||||
├── observations/
|
||||
│ └── observations.ndjson # Raw observations (for replay)
|
||||
├── keys/
|
||||
│ ├── signing-key.pub # Public key for DSSE verification
|
||||
│ └── rekor-key.pub # Rekor log public key
|
||||
└── trust/
|
||||
└── trust-root.json # Trust anchors for key verification
|
||||
```
|
||||
|
||||
**Manifest schema (witnesses section):**
|
||||
|
||||
```json
|
||||
{
|
||||
"schemaVersion": "2.0.0",
|
||||
"artifacts": [
|
||||
{
|
||||
"type": "witness",
|
||||
"path": "witnesses/<claim_id>.witness.dsse.json",
|
||||
"digest": "sha256:...",
|
||||
"predicateType": "https://stella.ops/predicates/runtime-witness/v1",
|
||||
"proofs": {
|
||||
"rekor": "proofs/rekor-inclusion.json",
|
||||
"checkpoint": "proofs/checkpoint.json",
|
||||
"tst": "proofs/rfc3161-tst.der"
|
||||
},
|
||||
"observationsRef": "observations/observations.ndjson"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### 17.5 Verification CLI Commands
|
||||
|
||||
```bash
|
||||
# Verify a witness bundle offline
|
||||
stella bundle verify --bundle witness-bundle.tar.gz --offline
|
||||
|
||||
# Verify with replay (recompute observations hash)
|
||||
stella bundle verify --bundle witness-bundle.tar.gz --offline --replay
|
||||
|
||||
# Verify specific witness from bundle
|
||||
stella witness verify --bundle witness-bundle.tar.gz --witness-id wit:sha256:abc123 --offline
|
||||
|
||||
# Export verification report
|
||||
stella witness verify --bundle witness-bundle.tar.gz --offline --output report.json
|
||||
```
|
||||
|
||||
### 17.6 Determinism Guarantees
|
||||
|
||||
The verification algorithm guarantees:
|
||||
|
||||
1. **Idempotent**: Running verification N times produces identical results.
|
||||
2. **Reproducible**: Different systems with the same bundle produce identical verification outcomes.
|
||||
3. **Isolated**: Verification requires no network access (fully air-gapped).
|
||||
4. **Auditable**: Every step produces evidence that can be independently checked.
|
||||
|
||||
**Test criteria** (per advisory):
|
||||
- Offline verifier reproduces the same mapping on 3 separate air-gapped runs.
|
||||
- No randomness in canonicalization, ordering, or hash computation.
|
||||
- Timestamps use UTC with fixed precision (milliseconds).

# Runtime Linkage Verification - Operational Runbook
|
||||
|
||||
> **Audience:** Platform operators, SREs, security engineers
|
||||
> **Related:** [Runtime Linkage Guide](../modules/scanner/guides/runtime-linkage.md), [Function Map V1 Contract](../contracts/function-map-v1.md)
|
||||
|
||||
## Overview
|
||||
|
||||
This runbook covers production deployment and operation of the runtime linkage verification system. The system uses eBPF probes to observe function calls and verifies them against declared function maps.
|
||||
|
||||
---
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Linux kernel 5.8+ (for eBPF CO-RE support)
|
||||
- `CAP_BPF` and `CAP_PERFMON` capabilities for the runtime agent
|
||||
- BTF (BPF Type Format) enabled in kernel config
|
||||
- Stella runtime agent deployed as a DaemonSet or sidecar
|
||||
|
||||
---
|
||||
|
||||
## Deployment
|
||||
|
||||
### Runtime Agent Configuration
|
||||
|
||||
The Stella runtime agent (`stella-runtime-agent`) attaches eBPF probes based on function map predicates. Configuration via environment or YAML:
|
||||
|
||||
```yaml
|
||||
runtime_agent:
|
||||
observation_store:
|
||||
type: "memory" # or "postgres", "valkey"
|
||||
retention_hours: 72
|
||||
max_batch_size: 1000
|
||||
probes:
|
||||
max_concurrent: 256
|
||||
attach_timeout_ms: 5000
|
||||
default_types: ["uprobe", "kprobe"]
|
||||
export:
|
||||
format: "ndjson"
|
||||
flush_interval_ms: 5000
|
||||
output_path: "/var/stella/observations/"
|
||||
```
|
||||
|
||||
### Probe Selection Guidance
|
||||
|
||||
| Category | Probe Type | Use Case |
|
||||
|----------|-----------|----------|
|
||||
| Crypto functions | `uprobe` | OpenSSL/BoringSSL/libsodium calls |
|
||||
| Network I/O | `kprobe` | connect/sendto/recvfrom syscalls |
|
||||
| Auth flows | `uprobe` | PAM/LDAP/OAuth library calls |
|
||||
| File access | `kprobe` | open/read/write on sensitive paths |
|
||||
| TLS handshake | `uprobe` | SSL_do_handshake, TLS negotiation |
|
||||
|
||||
**Prioritization:**
|
||||
1. Start with crypto and auth paths (highest security relevance)
|
||||
2. Add network I/O for service mesh verification
|
||||
3. Expand to file access for compliance requirements
|
||||
|
||||
### Resource Overhead
|
||||
|
||||
Expected overhead per probe:
|
||||
- CPU: ~0.1-0.5% per active uprobe (per-call overhead ~100ns)
|
||||
- Memory: ~2KB per attached probe + observation buffer
|
||||
- Disk: ~100 bytes per observation record (NDJSON)
|
||||
|
||||
**Recommended limits:**
|
||||
- Max 256 concurrent probes per node
|
||||
- Observation buffer: 64MB
|
||||
- Flush interval: 5 seconds
|
||||
- Retention: 72 hours (configurable)
|
||||

||||
## Operations
|
||||
|
||||
### Generating Function Maps
|
||||
|
||||
Run generation as part of CI/CD pipeline after SBOM generation:
|
||||
|
||||
```bash
|
||||
# In CI after SBOM generation
|
||||
stella function-map generate \
|
||||
--sbom ${BUILD_DIR}/sbom.cdx.json \
|
||||
--service ${SERVICE_NAME} \
|
||||
--hot-functions "crypto/*" --hot-functions "net/*" --hot-functions "auth/*" \
|
||||
--min-rate 0.95 \
|
||||
--window 1800 \
|
||||
--build-id ${CI_BUILD_ID} \
|
||||
--output ${BUILD_DIR}/function-map.json
|
||||
```
|
||||
|
||||
Store the function map alongside the container image (OCI referrer or artifact registry).
|
||||
|
||||
### Continuous Verification
|
||||
|
||||
Set up periodic verification (cron or controller loop):
|
||||
|
||||
```bash
|
||||
# Every 30 minutes, verify the last hour of observations
|
||||
stella function-map verify \
|
||||
--function-map /etc/stella/function-map.json \
|
||||
--from "$(date -d '1 hour ago' -Iseconds)" \
|
||||
--to "$(date -Iseconds)" \
|
||||
--format json --output /var/stella/verification/latest.json
|
||||
```
|
||||
|
||||
### Monitoring
|
||||
|
||||
Key metrics to alert on:
|
||||
|
||||
| Metric | Threshold | Action |
|
||||
|--------|-----------|--------|
|
||||
| `observation_rate` | < 0.80 | Warning: coverage dropping |
|
||||
| `observation_rate` | < 0.50 | Critical: significant coverage loss |
|
||||
| `unexpected_symbols_count` | > 0 | Investigate: undeclared functions executing |
|
||||
| `probe_attach_failures` | > 5% | Warning: probe attachment issues |
|
||||
| `observation_buffer_full` | true | Critical: observations being dropped |
|
||||
|
||||
### Alert Configuration
|
||||
|
||||
```yaml
|
||||
alerts:
|
||||
- name: "function-map-coverage-low"
|
||||
condition: observation_rate < 0.80
|
||||
severity: warning
|
||||
description: "Function map coverage below 80% for {service}"
|
||||
runbook: "Check probe attachment, verify no binary update without map regeneration"
|
||||
|
||||

|
||||
condition: unexpected_symbols_count > 0
|
||||
severity: info
|
||||
description: "Unexpected function calls detected in {service}"
|
||||
runbook: "Review unexpected symbols, regenerate function map if benign"
|
||||
|
||||

|
||||

|
||||
severity: warning

|
||||
runbook: "Check kernel version, verify BTF availability, check CAP_BPF"
|
||||
```
|
||||

||||

|
||||
|
||||
## Performance Tuning
|
||||
|
||||
### High-Traffic Services
|
||||
|
||||
For services with >10K calls/second on probed functions:
|
||||
|
||||
1. **Sampling:** Configure observation sampling rate:
|
||||
```yaml
|
||||
probes:
|
||||
sampling_rate: 0.01 # 1% of calls
|
||||
```
|
||||
|
||||
2. **Aggregation:** Use count-based observations instead of per-call:
|
||||
```yaml
|
||||
export:
|
||||
aggregation_window_ms: 1000 # Aggregate per second
|
||||
```
|
||||
|
||||
3. **Selective probing:** Use `--hot-functions` to limit to critical paths only
|
||||
|
||||
### Large Function Maps
|
||||
|
||||
For maps with >100 expected paths:
|
||||
|
||||
1. Tag paths by priority: `crypto` > `auth` > `network` > `general`
|
||||
2. Mark low-priority paths as `optional: true`
|
||||
3. Set per-tag minimum rates if needed
|
||||
|
||||
### Storage Optimization
|
||||
|
||||
For long-term observation storage:
|
||||
|
||||
1. Enable retention pruning: `pruneOlderThanAsync(72h)`
|
||||
2. Compress archived observations (gzip NDJSON)
|
||||
3. Use dedicated Postgres partitions by date for query performance
|
||||
|
||||
---
|
||||
|
||||
## Incident Response
|
||||
|
||||
### Coverage Dropped After Deployment
|
||||
|
||||
1. Check if binary was updated without regenerating the function map
|
||||
2. Verify probes are still attached: `stella observations query --summary`
|
||||
3. Check for symbol changes (ASLR, different build)
|
||||
4. Regenerate function map from new SBOM and redeploy
|
||||
|
||||
### Unexpected Symbols Detected
|
||||
|
||||
1. Identify the unexpected functions from the verification report
|
||||
2. Determine if they are:
|
||||
- **Benign:** Dynamic dispatch, plugins, lazy-loaded libraries → add to map
|
||||
- **Suspicious:** Unexpected crypto usage, network calls → escalate to security team
|
||||
3. If benign, regenerate function map with broader patterns
|
||||
4. If suspicious, correlate with vulnerability findings and open incident
|
||||
|
||||
### Probe Attachment Failures
|
||||
|
||||
1. Check kernel version: `uname -r` (need 5.8+)
|
||||
2. Verify BTF: `ls /sys/kernel/btf/vmlinux`
|
||||
3. Check capabilities: `capsh --print | grep bpf`
|
||||
4. Check binary paths: verify `binary_path` in function map matches deployed binary
|
||||
5. Check for SELinux/AppArmor blocking BPF operations
|
||||
|
||||

|
||||
|
||||
## Air-Gap Considerations
|
||||
|
||||
For air-gapped environments:
|
||||
|
||||
1. **Bundle generation** (connected side):
|
||||
```bash
|
||||
stella function-map generate --sbom app.cdx.json --service my-service --output fm.json
|
||||
# Package with observations
|
||||
tar czf linkage-bundle.tgz fm.json observations/*.ndjson
|
||||
```
|
||||
|
||||
2. **Transfer** via approved media to air-gapped environment
|
||||
|
||||
3. **Offline verification** (air-gapped side):
|
||||
```bash
|
||||
stella function-map verify --function-map fm.json --offline --observations obs.ndjson
|
||||
```
|
||||
|
||||
4. **Result export** for compliance reporting:
|
||||
```bash
|
||||
stella function-map verify ... --format json --output report.json
|
||||
# Sign the report
|
||||
stella attest sign --input report.json --output report.dsse.json
|
||||
```
