# 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:**
- SPRINT_20260122_037 (Trust Score Algebra)
- SPRINT_20260122_038 (eBPF Probe Type)
- SPRINT_20260122_039 (Runtime Linkage Verification)
**No upstream blockers.** This sprint wires existing services to CLI.

## Documentation Prerequisites
- `docs/modules/cli/guides/commands/reference.md` – current CLI structure
- `docs/modules/binary-index/architecture.md` – delta-sig design
- `docs/modules/attestor/guides/offline-verification.md` – bundle verification

### 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

Status: DONE
Dependency: none
Owners: Developer (BinaryIndex)
Task description:
Extend the delta-sig predicate schemas to reference external binary blobs and linked SBOMs, enabling the two-tier bundle format.
**Schema additions to `DeltaSigPredicate` (v1) and `DeltaSigPredicateV2`:**
```csharp
/// <summary>
/// SHA-256 digest of the associated SBOM document.
/// </summary>
[JsonPropertyName("sbomDigest")]
public string? SbomDigest { get; init; }
/// <summary>
/// References to large binary blobs stored out-of-band (by digest).
/// </summary>
[JsonPropertyName("largeBlobs")]
public IReadOnlyList<LargeBlobReference>? LargeBlobs { get; init; }
public record LargeBlobReference
{
/// <summary>
/// Blob kind: "preBinary", "postBinary", "debugSymbols", etc.
/// </summary>
[JsonPropertyName("kind")]
public required string Kind { get; init; }
/// <summary>
/// Content-addressable digest (e.g., "sha256:abc123...").
/// </summary>
[JsonPropertyName("digest")]

### 040-04 - Implement two-tier bundle format (light/full)
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
├── proofs/
│ ├── rekor-receipt.json
│ └── tst.der
├── sboms/
│ └── sbom.spdx.json
└── blobs/ # Only in Full mode
├── 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
```
**Files to modify:**
- `src/AirGap/__Libraries/StellaOps.AirGap.Bundle/Models/BundleExportMode.cs` (new)
- `src/AirGap/__Libraries/StellaOps.AirGap.Bundle/Services/BundleBuilder.cs`
- `src/AirGap/__Libraries/StellaOps.AirGap.Bundle/Models/BundleManifest.cs`
- `src/Cli/StellaOps.Cli/Commands/BundleExportCommand.cs`
Completion criteria:
- [x] `BundleExportMode.Light` produces bundle without binary blobs
- [x] `BundleExportMode.Full` includes all blobs from `largeBlobs[]`
- [x] `--full` flag added to `stella evidence export-bundle`
- [x] Light bundles remain small (<500KB for typical delta predicate)
- [x] Full bundles include binaries with correct digests
- [x] Manifest indicates mode: `"exportMode": "light"` or `"full"`
- [x] Unit tests: `BundleExportModeTests.cs` (9 tests, all passing)

### 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).
## Next Checkpoints
- TASK-01..04 complete: library layer functional, golden fixtures locked.
- TASK-05..07 complete: full stack (CLI + API) operational.
- TASK-08 complete: UI functional.
- TASK-10 complete: all integration tests green, sprint DONE.

# 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)

## 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).

> **DSSE Payload Type:** `application/vnd.stellaops.function-map.v1+json`
> **Schema Version:** `1.0.0`
## Overview
A function map predicate declares the expected call paths for a service component, enabling verification of runtime behavior against static analysis. It follows the [in-toto attestation](https://github.com/in-toto/attestation) framework.

"entrypoint": {
"symbol": "handleRequest",
"node_hash": "sha256:..."
},
"expected_calls": [
{

"node_hash": "sha256:...",
"probe_types": ["uprobe"],
"optional": false,
"function_address": null,
"binary_path": "/usr/lib/libcrypto.so.3"
}
],
"path_hash": "sha256:...",
"optional": false,
"strict_ordering": false,
"tags": ["crypto"]
}
```
| Field | Type | Required | Description |

| `window_seconds` | integer | 1800 | Observation window duration |
| `fail_on_unexpected` | boolean | false | Whether unexpected symbols cause verification failure |
---
## 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
```

## 5. References ## 5. Two-Tier Bundle Modes
> **Sprint:** SPRINT_20260122_040_Platform_oci_delta_attestation_pipeline (040-04, 040-06)
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"
├── attestations/
│ └── delta-sig.dsse.json
├── blobs/
│ ├── sha256-<hex1> # Binary patch blob
│ └── sha256-<hex2> # SBOM fragment blob
└── tsa/
├── chain/
└── 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

### 10.6 Related Documentation ### 10.6 Two-Tier Bundle Design and Large Blob References
> **Sprint:** SPRINT_20260122_040_Platform_oci_delta_attestation_pipeline (040-04)
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.

## Bundle Commands
### stella bundle verify
Verify offline evidence bundles with full cryptographic verification. Checks manifest integrity, blob digests, DSSE signatures, Rekor proofs, timestamps, payload types, and optionally replays large blob content verification.
**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 bundle verify \
--bundle /path/to/bundle \
--trust-root /etc/stellaops/tsa-root.pem \
--rekor-checkpoint checkpoint.json \
--replay \
--verbose
# Light bundle with local blob source
stella bundle verify \
--bundle light-bundle/ \
--replay \
--blob-source /path/to/blobs/
# Strict offline verification with signed report
stella bundle verify \
--bundle evidence-bundle/ \
--offline \
--strict \
--signer report-key.pem \
--signer-cert report-cert.pem
```
**Exit Codes:**
- `0` - All verifications passed
- `1` - One or more verifications failed
- `2` - Invalid input or configuration error

## 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
```bash
# Publish a CycloneDX SBOM to an image
stella sbom publish --image registry.example.com/myapp@sha256:abc123... --file app.cdx.json
# Publish with explicit format
stella sbom publish --image registry.example.com/myapp@sha256:abc123... --file app.json --format cdx
# Overwrite existing SBOM (supersede)
stella sbom publish --image registry.example.com/myapp@sha256:abc123... --file improved.cdx.json --overwrite
# Verbose output
stella sbom publish --image registry.example.com/myapp@sha256:abc123... --file app.cdx.json --verbose
```
### Sample Output
```
Published SBOM as OCI referrer:
Blob digest: sha256:e3b0c44298fc1c149afbf4c8996fb924...
Manifest digest: sha256:7d865e959b2466918c9863afca942d0f...
Version: 1
Artifact type: application/vnd.stellaops.sbom.cdx+json
```
### Verifier Discovery
Third-party verifiers can discover published SBOMs via the OCI referrers API:
```bash
# List SBOM referrers for an image (using oras CLI)
oras discover registry.example.com/myapp@sha256:abc123... \
--artifact-type application/vnd.stellaops.sbom.cdx+json
# Pull the latest SBOM
oras pull registry.example.com/myapp@sha256:abc123... \
--artifact-type application/vnd.stellaops.sbom.cdx+json
```

# 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
| Step | Check | Failure Behavior |
|------|-------|------------------|
| 1 | Manifest checksum | Fatal |
| 2 | Blob digests | Fatal |
| 3 | DSSE signatures | Fatal |
| 4 | Rekor proofs | Fatal (if checkpoint provided) |
| 5 | RFC 3161 timestamps | Fatal (in strict mode) |
| 6 | Payload type expectations | Warning (fatal in strict) |
| 7 | Blob replay | Fatal (when `--replay` enabled) |
## CI/CD Integration Example
```yaml
# .gitea/workflows/release.yaml
jobs:
attest:
steps:
- name: Generate delta predicate
run: |
stella binary delta-sig diff \
--old ${{ steps.build.outputs.old_binary }} \
--new ${{ steps.build.outputs.new_binary }} \
--output delta-predicate.json
- name: Sign and submit to Rekor
run: |
stella binary delta-sig attest \
--predicate delta-predicate.json \
--key ${{ secrets.SIGNING_KEY_PATH }} \
--output envelope.dsse.json \
--rekor-url https://rekor.sigstore.dev \
--receipt rekor-receipt.json
- name: Attach to image
run: |
stella attest attach \
--image ${{ env.REGISTRY }}/${{ env.IMAGE }}:${{ env.TAG }} \
--attestation envelope.dsse.json
- name: Export full bundle for auditors
run: |
stella evidence export-bundle \
--image ${{ env.REGISTRY }}/${{ env.IMAGE }}:${{ env.TAG }} \
--output evidence-bundle.tar.gz \
--full
```
## Troubleshooting
| Issue | Cause | Resolution |
|-------|-------|------------|
| `Blob Replay ✗` | Missing blobs in light bundle | Use `--blob-source` or export with `--full` |
| `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
RemediationHint:
Code: Machine-readable (e.g., "CVSS_EXCEED")
Title: Human-readable summary
Actions[]: CLI command templates with {placeholders}
References: External documentation links
Severity: critical | high | medium | low
```
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
## API Endpoints
The Platform API exposes policy interop at `/api/v1/policy/interop`:
| Method | Path | Description |
|--------|------|-------------|
| POST | `/export` | Export policy to format |
| POST | `/import` | Import policy from format |
| POST | `/validate` | Validate policy document |
| POST | `/evaluate` | Evaluate policy against input |
| GET | `/formats` | List supported formats |
## Gate Types
Supported gate types with Rego translation:
| 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` |

# 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

# Unified Trust Score
> **Ownership:** Signals Guild / Platform Guild
> **Services:** `StellaOps.Signals.UnifiedScore`
> **API:** `POST /api/v1/score/evaluate`, `GET /api/v1/score/{id}/replay`
> **CLI:** `stella score compute|explain|replay|verify`, `stella gate score evaluate`
## 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.

```
---
## 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"
- name: "function-map-unexpected-calls"
condition: unexpected_symbols_count > 0
severity: info
description: "Unexpected function calls detected in {service}"
runbook: "Review unexpected symbols, regenerate function map if benign"
- name: "function-map-probe-failures"
condition: probe_attach_failure_rate > 0.05
severity: warning
description: "Probe attachment failure rate above 5%"
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
```
