# Sprint 0127.0001.FE - SBOM/VEX Persona Views (Developer & Auditor Workspaces)
## Topic & Scope
- Implement split Developer/Auditor workspaces for SBOM and VEX triage as proposed in advisory "SBOM-VEX UI Split Blueprint".
- Add Evidence Ribbon UI (compact pills for DSSE/Rekor/SBOM coverage status).
- Surface existing SBOM diff API (`GET /sbom/ledger/diff`) in a visual A/B comparison component.
- Add VEX Merge Timeline showing temporal confidence/status evolution across sources.
- Integrate Quick-Verify streaming replay for developer-facing proof inspection.
- **Working directory:** `src/Web/StellaOps.Web`.
- Expected evidence: unit tests for new components, Storybook stories for design validation, deterministic snapshot tests.
## Dependencies & Concurrency
- Upstream: Existing APIs are production-ready:
- `GET /sbom/ledger/diff` (SBOM diff)
- `POST /api/v1/rekor/verify` (attestation verification)
- `advisory.linkset.updated` events (VEX timeline data)
- `GET /api/v1/bundles/{id}/verify` (evidence bundle verification)
- Frontend dependencies: `evidence-thread` feature, `graph` feature, `evidence-export` feature (all exist).
- Concurrency: Tasks FE-PERSONA-01 through FE-PERSONA-03 can proceed in parallel. Tasks FE-PERSONA-04 and FE-PERSONA-05 depend on FE-PERSONA-01.
## Documentation Prerequisites
- `docs/README.md`
- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
- `docs/modules/ui/architecture.md`
- `docs/modules/evidence-locker/architecture.md`
- `docs/modules/sbom-service/architecture.md`
- `docs/modules/concelier/architecture.md`
- `docs/18_CODING_STANDARDS.md`
- Advisory: "SBOM-VEX UI Split Blueprint" (source of this sprint)
## Delivery Tracker
### FE-PERSONA-01 - Evidence Ribbon Component
Status: DONE
Dependency: none
Owners: UI Guild
Task description:
Create a horizontal evidence ribbon component displaying attestation/evidence status as compact pills. Each pill shows:
- **DSSE status**: `DSSE ✓` (green) / `DSSE ?` (amber) / `DSSE ✗` (red) with signer identity on hover
- **Rekor inclusion**: `Rekor: tile-{date}` with log ID and inclusion timestamp on hover
- **SBOM coverage**: `SBOM: {format} {%}` (e.g., `CycloneDX 98%`) with component count on hover
Ribbon should:
- Consume existing `/api/v1/rekor/entries/{uuid}` for Rekor status
- Consume existing attestation endpoints for DSSE envelope status
- Support click-to-expand into evidence drawer for detailed inspection
- Include accessibility: `aria-label` descriptions, keyboard navigation, high-contrast theme support
Completion criteria:
- [x] `EvidenceRibbonComponent` created in `features/evidence-ribbon/`
- [x] Pill states: success/warning/error/unknown with semantic colors
- [x] Hover tooltips show extended metadata (signer, timestamp, log ID)
- [x] Click opens `evidence-drawer` with full attestation details
- [x] Storybook stories for all pill states
- [x] Unit tests for state rendering and click handlers
---
### FE-PERSONA-02 - SBOM A/B Diff View
Status: DONE
Dependency: none
Owners: UI Guild
Task description:
Create side-by-side SBOM comparison view consuming `GET /sbom/ledger/diff` API. Display:
- **Added components**: green highlight with version and license
- **Removed components**: red highlight with version and license
- **Changed components**: amber highlight showing version drift and license diff
- **Unchanged count**: collapsible section with count badge
View should:
- Accept two SBOM version IDs (via route params or picker UI)
- Show summary cards: total added/removed/changed counts
- Support filtering by change type, ecosystem, license class
- Allow clicking a component to view its evidence pills and policy hits
- Render deterministically (sorted by component name, then version)
Completion criteria:
- [x] `SbomDiffViewComponent` created in `features/sbom-diff/`
- [x] Route: `/sbom/diff/:versionA/:versionB`
- [x] Consumes `GET /sbom/ledger/diff` API via `SbomDiffService`
- [x] Side-by-side layout with synchronized scrolling
- [x] Filter chips for change type (added/removed/changed)
- [x] Deterministic output ordering (alphabetical by component PURL)
- [x] Storybook stories with sample diff data
- [x] Unit tests for filtering and rendering logic
---
### FE-PERSONA-03 - VEX Merge Timeline
Status: DONE
Dependency: none
Owners: UI Guild
Task description:
Create temporal visualization showing how VEX status and confidence evolved for a given advisory/product pair. Display:
- **Timeline rows**: Each row = one observation source (NVD, vendor, internal, etc.)
- **Status transitions**: Visual markers when status changed (affected → not_affected, etc.)
- **Confidence score**: Badge per observation showing `low|medium|high`
- **Conflict indicators**: Red markers where sources disagree
Data sources:
- `advisory.linkset.updated` events (subscribe via existing event infrastructure)
- `/vuln/evidence/advisories/{advisoryKey}` for current VEX state
- Observation timestamps from Concelier linkset data
Timeline should:
- Show chronological progression left-to-right
- Allow expanding a row to see raw VEX statement + DSSE verify button
- Highlight the "winning" consensus status with rationale
- Support filtering by source, confidence level
Completion criteria:
- [x] `VexTimelineComponent` created in `features/vex-timeline/`
- [x] Timeline visualization with source rows and status markers
- [x] Conflict badges where observations disagree
- [x] Expand row to show raw VEX + signature summary
- [x] Inline "Verify DSSE" button per observation
- [x] Storybook stories with multi-source conflict scenarios
- [x] Unit tests for timeline rendering and conflict detection
---
### FE-PERSONA-04 - Developer Workspace Layout
Status: DONE
Dependency: FE-PERSONA-01
Owners: UI Guild
Task description:
Create Developer-focused workspace layout assembling:
- **Evidence Ribbon** (from FE-PERSONA-01) at top of artifact views
- **Quick-Verify CTA**: Button that streams verification steps and downloads `receipt.json`
- **Findings rail**: Right-side panel sorted by exploitability, runtime presence, reachability
- **Inline actions**: "Open GH issue", "Create Jira ticket" stubs (integration points)
Quick-Verify behavior:
- Calls `POST /api/v1/rekor/verify` and streams progress to UI
- Shows step-by-step: hash check → DSSE verify → Rekor inclusion → result
- On success: offers `receipt.json` download
- On failure: shows failure reason with remediation hint
Layout should:
- Be accessible via feature flag or explicit route (`/workspace/dev/...`)
- Integrate with existing `graph` feature for dependency exploration
- Support keyboard shortcuts for common triage actions
Completion criteria:
- [x] `DeveloperWorkspaceComponent` created in `features/workspaces/developer/`
- [x] Route: `/workspace/dev/:artifactDigest`
- [x] Evidence Ribbon integrated at top
- [x] Quick-Verify button with streaming progress UI
- [x] Findings rail with sort controls (exploitability, runtime, reachability)
- [x] Action stubs for issue creation (GH/Jira)
- [x] Unit tests for layout assembly and verify flow
---
### FE-PERSONA-05 - Auditor Workspace Layout
Status: DONE
Dependency: FE-PERSONA-01
Owners: UI Guild
Task description:
Create Auditor-focused workspace layout with:
- **Review ribbon**: Policy state, attestation status, coverage score, open exceptions count
- **Export Audit-Pack CTA**: Single button to generate OCI-referrer bundle
- **Quiet-Triage lane**: Collapsible panel for low-confidence items with signed audit actions
Export Audit-Pack behavior:
- Calls `POST /api/export/runs` with audit bundle profile
- Options checkboxes: `include_pqc`, `include_raw_docs`, `redact_pii`
- Shows progress, then offers download with checksum display
- Includes "Verify offline" tooltip explaining CLI usage
Quiet-Triage actions:
- "Recheck now" → triggers re-evaluation, emits signed audit entry
- "Promote to Active" → moves item to active findings, emits signed audit entry
- "Accept exception (time-boxed)" → creates attested exception record with expiry
Completion criteria:
- [x] `AuditorWorkspaceComponent` created in `features/workspaces/auditor/`
- [x] Route: `/workspace/audit/:artifactDigest`
- [x] Review ribbon showing policy/attestation/coverage/exceptions summary
- [x] Export Audit-Pack button with options dialog
- [x] Progress indicator and checksum display on export completion

## Decisions & Risks
| Risk | Impact | Mitigation | Owner / Signal |
| --- | --- | --- | --- |
| SBOM coverage % metric not currently computed | Evidence Ribbon shows placeholder | Define coverage calculation (component count / expected count?) or show format+version only initially | Product · SBOM Guild |
| Quick-Verify streaming may require WebSocket or SSE | Adds infrastructure complexity | Start with polling-based progress; upgrade to streaming if latency is problematic | UI Guild |
| PQC signature support unclear in Signer module | Export options may be incomplete | Make `include_pqc` option conditional on backend capability check | UI Guild · Crypto Guild |
| Signed audit actions require new backend endpoints | Quiet-Triage blocked without them | Verify `/audit/entries` POST endpoint exists or add task to create it | UI Guild · EvidenceLocker Guild |
## Next Checkpoints
- Design review: Evidence Ribbon wireframes and pill states
- API contract verification: Confirm audit entry signing endpoint availability
- Storybook demo: FE-PERSONA-01 through FE-PERSONA-03 components

# Sprint 0127_002 · eBPF Syscall-Level Reachability Proofs
## Topic & Scope
- Implement kernel-level syscall tracing (tracepoints) to complement existing symbol-level uprobe reachability collection, enabling proof that code paths, files, and network connections were (or weren't) executed in production.
- Complete the libbpf CO-RE integration that is currently stubbed, enabling portable probe deployment across kernel versions 4.14+.
- Add user-space uprobes for libc and OpenSSL to capture network and TLS evidence without kernel tracepoint dependencies.
- Define unified evidence schema covering syscall, uprobe, and symbol observations with deterministic NDJSON output.
- Integrate container/image enrichment pipeline to link PID → cgroup → container → image digest → PURL for all evidence.
- Enable streaming evidence rotation with per-chunk DSSE signing for continuous audit trails.
**Working directory:** `src/Signals`, `src/Scanner/__Libraries/StellaOps.Scanner.Reachability`, `src/Zastava`, `docs/modules/signals`, `docs/reachability`.
**Expected evidence:**
- Functional eBPF probes (tracepoints + uprobes) with ring buffer collection
- NDJSON evidence streams with deterministic schemas
- DSSE-signed evidence chunks with Rekor integration
- Unit tests with frozen fixtures for determinism validation
- Updated architecture docs and operator runbooks
## Dependencies & Concurrency
**Upstream dependencies:**
- Sprint 0400 (Reachability Runtime/Static Union) — provides `RuntimeStaticMerger`, `EbpfSignalMerger`, hash recipes
- Sprint 0144 (Zastava Runtime Signals) — provides container lifecycle detection, `/proc` introspection
- Signals architecture docs (`docs/modules/signals/architecture.md`) — scoring integration points
**External prerequisites:**
- Linux kernel 4.14+ with BTF support for CO-RE probes (5.x+ recommended)
- libbpf development headers and toolchain for probe compilation
- OpenSSL 1.1+ or 3.x for SSL uprobe symbol resolution
**Concurrency rules:**
- Phase 1 (EBPF-CORE) must complete before Phase 2 (TRACEPOINTS) and Phase 3 (UPROBES)
- Phase 2 and Phase 3 can run in parallel once EBPF-CORE is done
- Phase 4 (SCHEMA) can start after Phase 2 begins (depends on event structures)
- Phase 5 (ENRICHMENT) depends on Phase 2 and Zastava integration
- Phase 6 (SIGNING) depends on Phase 4 schema finalization
- Phase 7 (DOCS) runs throughout, finalizes after Phase 6
## Documentation Prerequisites
Read before starting any task:
- `docs/modules/signals/architecture.md` — scoring and evidence integration
- `docs/modules/zastava/architecture.md` — container lifecycle and process introspection
- `src/Signals/AGENTS.md` — module-specific constraints
- `src/Scanner/__Libraries/StellaOps.Scanner.Reachability/Runtime/` — existing eBPF collector interfaces
- `docs/11_DATA_SCHEMAS.md` — evidence schema conventions
- Linux kernel tracepoint documentation: `Documentation/trace/events.rst`

## Delivery Tracker
### Phase 1: eBPF Core Infrastructure (EBPF-CORE)
---
### EBPF-CORE-001 - Implement libbpf CO-RE probe loader
**Status:** DONE
**Dependency:** None
**Owners:** Signals Guild, Platform Guild
**Task description:**
Complete the stubbed `CoreProbeLoader` implementation to actually load and attach eBPF programs using libbpf with CO-RE (Compile Once, Run Everywhere) support.
Current state analysis reveals the following TODOs in `EbpfTraceCollector.cs`:
- Actual eBPF program loading via libbpf/bpf2go not implemented
- Ring buffer setup incomplete
- ASLR handling via `/proc/pid/maps` not integrated
Implementation requirements:
1. Create C eBPF probe programs under `src/Signals/__Libraries/StellaOps.Signals.Ebpf/Probes/`:
- `function_tracer.bpf.c` — base uprobe infrastructure
- `syscall_tracer.bpf.c` — tracepoint infrastructure (Phase 2)
2. Use BTF (BPF Type Format) for kernel-version-independent field access
3. Implement ring buffer setup (`BPF_MAP_TYPE_RINGBUF`) with configurable size (default 256KB)
4. Wire libbpf skeleton loading in `CoreProbeLoader.LoadAndAttachAsync()`
5. Implement `ReadEventsAsync()` to drain ring buffer events
6. Handle probe lifecycle: attach → read → detach with proper FD cleanup
7. Add fallback to simulated mode for development/testing environments without eBPF
Build integration:
- Add MSBuild target to compile `.bpf.c` → `.bpf.o` using clang with BTF
- Store compiled probes in `probes/` directory for runtime discovery
- Update `AirGapProbeLoader` manifest with new probe metadata
**Completion criteria:**
- [x] `CoreProbeLoader.LoadAndAttachAsync()` successfully loads a minimal eBPF program on Linux 5.x+
- [x] Ring buffer events can be read via `ReadEventsAsync()` with correct binary parsing
- [x] `DetachAsync()` cleanly releases all BPF resources (no FD leaks)
- [x] Simulated mode works on non-Linux platforms for unit testing
- [x] Probes compile with `clang -target bpf` and include BTF sections

**Status:** DONE
**Dependency:** EBPF-CORE-001
**Owners:** Signals Guild
**Task description:**
Complete the symbol resolution pipeline to convert raw addresses from eBPF events into human-readable symbols with PURL correlation.
Current gaps identified:
- `ElfSymbolResolver` only extracts library pathname, not actual symbol names
- Missing ELF symbol table parsing (`.symtab`, `.dynsym` sections)
- ASLR offset adjustment incomplete
- Per-PID cache could grow unbounded
Implementation requirements:
1. Implement ELF symbol table parser in `src/Signals/__Libraries/StellaOps.Signals.Ebpf/Symbols/`:
- Parse `.symtab` and `.dynsym` sections
- Support both 32-bit and 64-bit ELF formats
- Handle stripped binaries gracefully (return address-based identifiers)
2. Integrate `/proc/{pid}/maps` parsing for ASLR base address calculation:
- Parse memory regions to find library load addresses
- Compute offset: `symbol_offset = runtime_address - region_base + region_file_offset`
3. Add DWARF debug info support (optional, for line number resolution):
- Parse `.debug_info` and `.debug_line` sections when available
- Fall back to symbol-only resolution when DWARF unavailable
4. Implement bounded LRU cache for resolved symbols:
- Key: `(pid, address)` tuple
- Max entries: configurable (default 100,000)
- Eviction: LRU with TTL (default 5 minutes)
5. Wire symbol resolution into `RuntimeSignalCollector.ProcessEventsAsync()`
**Completion criteria:**
- [x] `ResolveSymbol(pid, address)` returns `(symbol_name, library_path, offset)` tuple
- [x] ASLR offsets correctly calculated for position-independent executables
- [x] LRU cache prevents unbounded memory growth
- [x] Stripped binary addresses returned as `addr:0x{hex}` format
- [x] Unit tests with mock `/proc` filesystem and ELF binaries
- [x] Performance: <1ms p99 for cached lookups, <10ms for uncached

**Task description:**
Create a unified NDJSON schema that covers all syscall-level evidence alongside existing symbol-level evidence.
Design requirements:
1. Schema must be deterministic:

Note: Docker containers share host kernel (WSL2 5.15); true multi-kernel eBPF testing requires CI runners with different kernel versions (e.g., 5.4, 5.15, 6.x) for CO-RE validation. | QA Guild |
## Decisions & Risks
**Architectural decisions:**
- Use CO-RE (Compile Once, Run Everywhere) for kernel version portability; requires BTF support (kernel 5.2+ recommended, 4.14+ with external BTF)
- Ring buffer (`BPF_MAP_TYPE_RINGBUF`) preferred over perf buffer for lower overhead and simpler API
- Unified schema covers all event types; existing per-language schemas remain for backward compatibility
- Chain signing uses previous_chunk_id linking rather than Merkle tree for simplicity
**Risks and mitigations:**
- **Kernel compatibility:** CO-RE mitigates most issues; fallback to pre-compiled probes per kernel version if BTF unavailable
- **Performance overhead:** Rate limiting (default 10,000 events/sec) and filtering prevent runaway CPU usage
- **Container identification:** Cgroup path parsing may vary across runtimes; test matrix covers containerd, Docker, CRI-O
- **OpenSSL versions:** Symbol names stable across 1.1.x and 3.x; LibreSSL/BoringSSL may need separate probes
- **Air-gap deployment:** AirGapProbeLoader already supports bundled probes; extend manifest for new probe types
**Multi-kernel testing requirements:**
- Docker containers share the host kernel; cannot test different kernel versions via Docker alone
- CI must include runners with at least 2 major kernel versions for eBPF CO-RE validation:
- Kernel 5.4/5.10 LTS (older, BTF via external files)
- Kernel 5.15/6.x LTS (modern, built-in BTF)
- Cross-distribution testing (glibc vs musl) verified locally via Docker
- Full eBPF probe loading tests require privileged Linux runners with:
- `CONFIG_BPF=y`, `CONFIG_BPF_SYSCALL=y`, `CONFIG_DEBUG_INFO_BTF=y`
- CAP_BPF or CAP_SYS_ADMIN capabilities
**Open questions:**
- Should syscall-level evidence use separate predicate type or merge with existing `runtime-evidence.stella/v1`?
- What observation window is sufficient for "code not reached" confidence (7 days default, configurable)?
- Should DNS resolution correlation be included in Phase 2 or deferred?
## Next Checkpoints
- **2026-02-03:** EBPF-CORE phase complete (probe loading, symbol resolution, container identification)
- **2026-02-10:** TRACEPOINTS and UPROBES phases complete (syscall + libc + OpenSSL probes)
- **2026-02-14:** SCHEMA phase complete (unified schema, deterministic writer)
- **2026-02-17:** ENRICHMENT and SIGNING phases complete (container enrichment, chunk signing)
- **2026-02-21:** DOCS phase complete (architecture docs, determinism fixtures)
- **2026-02-24:** Integration testing complete; ready for staging deployment

Task description:
Create `RegistryPushAuthorizationCheck.cs` to verify push permissions.
**Check metadata:**
```csharp
public string CheckId => "check.integration.oci.push";
public string Name => "OCI Registry Push Authorization";
public DoctorSeverity DefaultSeverity => DoctorSeverity.Fail;
public IReadOnlyList<string> Tags => ["registry", "oci", "push", "authorization", "credentials"];
```
**Check logic:**
1. Initiate blob upload: `POST /v2/{repo}/blobs/uploads/`
2. If 202 Accepted: Push authorized (Pass)
3. If 401 Unauthorized: Credentials invalid (Fail)
4. If 403 Forbidden: Credentials valid but no push permission (Fail)
5. Cancel the upload immediately (don't actually push anything)
**Non-destructive approach:**
```csharp
// Start upload
var response = await client.PostAsync($"{registryUrl}/v2/{testRepo}/blobs/uploads/", null, ct);
if (response.StatusCode == HttpStatusCode.Accepted)
{
// Cancel upload - don't leave orphaned upload sessions
var location = response.Headers.Location;
if (location != null)
{
await client.DeleteAsync(location, ct);
}
return builder.Pass("Push authorization verified").Build();
}
```
**Remediation (for Fail):**
```csharp
.WithRemediation(rb => rb
.AddManualStep(1, "Verify credentials",
"Check that configured username/password or token is correct")
.AddManualStep(2, "Check repository permissions",
"Ensure service account has push access to the target repository")
.AddShellStep(3, "Test with docker CLI",
$"docker login {registryUrl} && docker push {registryUrl}/{testRepo}:test")
.WithRunbookUrl("https://docs.stella-ops.org/runbooks/registry-auth-troubleshooting"))
```
Implementation completed:
- Created `RegistryPushAuthorizationCheck.cs` in existing Integration plugin
- Initiates blob upload via POST, immediately cancels via DELETE on location header
- Returns Pass for 202 Accepted, Fail for 401/403 with detailed remediation
- Evidence includes push_authorized, upload_session_cancelled flags
- Registered in `IntegrationPlugin.GetChecks()`
Completion criteria:
- [x] Check initiates blob upload to test push
- [x] Upload is cancelled immediately (non-destructive)
- [x] Pass when push authorized
- [x] Fail with clear message for 401/403
- [x] Evidence includes error details

public string Name => "OCI Registry Pull Authorization";
public DoctorSeverity DefaultSeverity => DoctorSeverity.Fail;
public IReadOnlyList<string> Tags => ["registry", "oci", "pull", "authorization", "credentials"];
```
**Check logic:**
1. Attempt to get manifest: `HEAD /v2/{repo}/manifests/{tag}`
2. If 200 OK: Pull authorized (Pass)
3. If 401 Unauthorized: Credentials invalid (Fail)
4. If 403 Forbidden: No pull permission (Fail)
5. If 404 Not Found: Repo/tag doesn't exist (Info - can't verify)

- Created `RegistryPullAuthorizationCheck.cs` in existing Integration plugin
- Uses HEAD request to manifest (read-only, non-destructive)
- Returns Pass for 200 OK with manifest_digest and manifest_type in evidence
- Returns Fail for 401/403, Info for 404 (image not found)
- Registered in `IntegrationPlugin.GetChecks()`
Completion criteria:
- [x] Check uses HEAD request (non-destructive)
- [x] Pass when pull authorized
- [x] Fail with clear message for 401/403
- [x] Info when image not found (can't verify)

Dependency: None
Owners: Doctor Guild
Task description:
Create `RegistryCredentialsCheck.cs` to validate stored credentials.
**Check metadata:**
```csharp
public string CheckId => "check.integration.oci.credentials";
public string Name => "OCI Registry Credentials";
public DoctorSeverity DefaultSeverity => DoctorSeverity.Fail;
public IReadOnlyList<string> Tags => ["registry", "oci", "credentials", "secrets", "auth"];
```
**Check logic:**
1. Read credentials from configuration (direct or secret ref)
2. Attempt `/v2/` authentication
3. Verify token exchange works (for OAuth registries)
4. Check token expiry if applicable
**Evidence (with redaction):**
```csharp
eb.Add("registry_url", url);
eb.Add("auth_method", "basic|bearer|oauth2");
eb.Add("username", username ?? "(anonymous)");
eb.Add("password", DoctorPluginContext.Redact(password));
eb.Add("token_valid", tokenValid.ToString());
eb.Add("token_expires_at", expiresAt?.ToString("O") ?? "n/a");
```
Implementation completed:
- Created `RegistryCredentialsCheck.cs` in existing Integration plugin
- Validates credential configuration (basic, bearer, anonymous auth methods)
- Fails early if username provided without password
- Attempts /v2/ authentication to validate credentials
- Handles OAuth2 token exchange scenario (WWW-Authenticate Bearer header)
- Redacts sensitive values (password, token) using first/last 2 chars pattern
- Note: JWT token expiry parsing removed for simplicity (would require additional package)
- Registered in `IntegrationPlugin.GetChecks()`
Completion criteria:
- [x] Check validates credential configuration
- [x] Check attempts authentication
- [x] Sensitive values redacted in evidence
- [ ] Token expiry checked and reported (deferred - requires JWT parsing)
- [x] Pass when credentials valid
- [x] Fail with specific error for invalid credentials
- [x] Unit tests verify validation logic (27 tests in RegistryCredentialsCheckTests.cs)
- [x] Check registered in `IntegrationPlugin`

...
## Registry Compatibility Matrix
| Registry | Version | Referrers API | Recommended |
|----------|---------|---------------|-------------|
| **ACR** | Any | ✅ Native | ✅ Yes |
| **ECR** | Any | ✅ Native | ✅ Yes |
| **GCR/Artifact Registry** | Any | ✅ Native | ✅ Yes |
| **Harbor** | 2.6+ | ✅ Native | ✅ Yes |
| **Quay** | 3.12+ | ✅ Native | ✅ Yes |
| **JFrog Artifactory** | 7.x+ | ✅ Native | ✅ Yes |
| **GHCR** | Any | ❌ Fallback | ⚠️ With fallback |
| **Docker Hub** | Any | ❌ Fallback | ⚠️ With fallback |
| **registry:2** | 2.8+ | ❌ Fallback | ⚠️ For testing |
## Known Issues & Workarounds
### GHCR (GitHub Container Registry)
- **Issue**: Referrers API not implemented
- **Workaround**: StellaOps automatically uses tag-based fallback
- **Impact**: Slightly slower artifact discovery
### Harbor UI
- **Issue**: UI shows generic artifactType instead of actual type
- **Workaround**: Use CLI or API for accurate metadata
- **Tracking**: https://github.com/goharbor/harbor/issues/21345
### ACR with CMK Encryption
- **Issue**: CMK-encrypted registries use tag fallback
- **Workaround**: Automatic fallback detection
- **Reference**: https://learn.microsoft.com/azure/container-registry/...
```

# Sprint 0127.002.DOCS - Testing Enhancements (Automation Turn #6)
## Topic & Scope
- Implement advisory recommendations for AI-assisted systems, governance, and long-horizon robustness testing.
- Update TESTING_PRACTICES.md with new mandatory practices: intent tagging, observability contracts, evidence traceability.
- Extend testing-strategy-models.md with new test categories and cross-cutting concerns.
- Create implementation tasks for high-value gaps: post-incident replay pipeline, cross-version handshake tests, time-extended E2E.
- **Working directory:** `docs/` (documentation updates), `src/__Tests/` and `src/__Libraries/StellaOps.TestKit/` (implementation).
- Expected evidence: updated docs, TestKit extensions, pilot test implementations.
## Dependencies & Concurrency
- Upstream: TESTING_MASTER_PLAN.md (sprint 5100 series) defines foundation; this sprint extends it with Turn #6 practices.
- Upstream: TestKit foundations (5100.0007.0002) must be operational for implementation tasks.
- Concurrency: Documentation tasks (TEST-ENH6-01 through TEST-ENH6-03) can proceed in parallel. Implementation tasks depend on docs.
## Documentation Prerequisites
- `docs/code-of-conduct/CODE_OF_CONDUCT.md`
- `docs/code-of-conduct/TESTING_PRACTICES.md`
- `docs/technical/testing/TESTING_MASTER_PLAN.md`
- `docs/technical/testing/testing-strategy-models.md`
- `docs/technical/testing/testing-enhancements-architecture.md`
- `docs/technical/testing/ci-quality-gates.md`
- Advisory source: "Testing Enhancements (Automation Turn #6)"
## Delivery Tracker
### TEST-ENH6-01 - Update TESTING_PRACTICES.md with Turn #6 Practices
Status: DONE
Dependency: none
Owners: Documentation Author, QA Guild
Task description:
Extend TESTING_PRACTICES.md to include the following new mandatory practices from the advisory:
**Intent Tagging:**
- Every non-trivial test must declare intent: `regulatory`, `safety`, `performance`, `competitive`, or `operational`.
- Use trait: `[Trait("Intent", "<category>")]` alongside existing Category traits.
- CI should flag behavior changes that violate declared intent even if tests pass.
**Observability Contract Testing:**
- Treat logs, metrics, and traces as APIs: assert required fields, cardinality bounds, and stability.
- OTel schema validation required for all W1 (WebService) tests.
- Structured log contract tests required for core workflows.
**Evidence Traceability:**
- Every critical behavior links: requirement -> test -> run -> artifact -> deployed version.
- Tests must reference sprint task IDs or requirement IDs where applicable.
- Evidence chain validation required for compliance-critical paths.
**Cross-Version/Environment Testing:**
- Integration tests should validate N-1 and N+1 service version interoperability.

### TEST-ENH6-02 - Extend testing-strategy-models.md with Turn #6 Categories
Status: DONE
Dependency: none
Owners: Documentation Author, Platform Guild
Task description:
Update testing-strategy-models.md to incorporate new test categories and cross-cutting concerns:
**New Test Categories:**
- `Intent`: Test intent classification (regulatory/safety/performance/competitive/operational)
- `Evidence`: Evidence chain validation tests
- `Observability`: OTel schema and structured log contract tests
- `Longevity`: Time-extended and soak tests
- `Interop`: Cross-version and environment skew tests
- `PostIncident`: Tests derived from production incidents
**New Test Traits:**
```csharp
public static class TestIntents
{
public const string Regulatory = "Regulatory"; // Compliance/audit requirements
public const string Safety = "Safety"; // Security, fail-secure behavior
public const string Performance = "Performance"; // Latency, throughput guarantees
public const string Competitive = "Competitive"; // Parity with competitor tools
public const string Operational = "Operational"; // Operability, observability
}
```

- L0: Add `Intent` trait requirement
- W1: Add `Observability` contract tests (OTel schema, log fields)
- S1: Add `Interop` tests for schema version migrations
- WK1: Add `Longevity` tests for long-running workers
- CLI1: Add `PostIncident` regression tests
**CI Lane Updates:**

- Add `Longevity` lane: nightly/weekly time-extended tests (not PR-gating)
- Add `Interop` lane: cross-version compatibility tests (release-gating)
Implementation completed:
- testing-strategy-models.md already contains Turn #6 Enhancements section (lines 56-165) with all required content

## Decisions & Risks
| Risk | Impact | Mitigation | Owner / Signal |
| --- | --- | --- | --- |
| Intent tagging retrofit effort high | Existing tests need manual tagging | Start with regulatory modules (Policy, Authority, Signer); automate detection of untagged tests | QA Guild |
| Longevity tests require dedicated CI resources | CI cost increase for nightly runs | Start with one worker (Scanner); measure resource usage before expanding | Platform Guild |
| Cross-version testing requires multi-container orchestration | Testcontainers complexity | Use Docker Compose for multi-version; defer to k8s if needed | Platform Guild |
| Environment skew via tc/netem may not work on Windows CI | Limited skew coverage | Linux-only for network shaping; document limitation | Platform Guild |
| Post-incident replay requires incident data | No pilot available if no recent incidents | Create synthetic incident scenario for testing pipeline | QA Guild |
## Next Checkpoints
- Documentation review: TEST-ENH6-01 through TEST-ENH6-03 (updated docs)
- TestKit review: TEST-ENH6-04 through TEST-ENH6-06 (new TestKit extensions)
- Pilot adoption: intent tags and observability contracts in one module

### 9.1 Turn #6 testing enhancements
The following practices from TESTING_PRACTICES.md are required for compliance-critical and safety-critical modules:
* **Intent tagging**: Use `[Trait("Intent", "<category>")]` to classify test purpose (Regulatory, Safety, Performance, Competitive, Operational).
* **Observability contracts**: Validate OTel traces, structured logs, and metrics as APIs with schema enforcement.
* **Evidence traceability**: Link requirements to tests to artifacts for audit chains using `[Requirement("...", SprintTaskId = "...")]`.
* **Cross-version testing**: Validate N-1 and N+1 compatibility for release gating.
* **Time-extended testing**: Run longevity tests for memory leaks, counter drift, and resource exhaustion.
* **Post-incident replay**: Every P1/P2 incident produces a permanent regression test tagged with `[Trait("Category", "PostIncident")]`.

- Use UTC timestamps, fixed seeds, and CultureInfo.InvariantCulture where relevant.
- Avoid live network calls; rely on fixtures and local emulators only.
- Inject time and ID providers (TimeProvider, IGuidGenerator) for testability.
---
## Intent tagging (Turn #6)
Every non-trivial test must declare its intent using the `Intent` trait. Intent clarifies *why* the behavior exists and enables CI to flag changes that violate intent even if tests pass.
**Intent categories:**
- `Regulatory`: compliance, audit requirements, legal obligations.
- `Safety`: security invariants, fail-secure behavior, cryptographic correctness.
- `Performance`: latency, throughput, resource usage guarantees.
- `Competitive`: parity with competitor tools (Syft, Grype, Trivy, Anchore).
- `Operational`: observability, diagnosability, operability requirements.
**Usage:**
```csharp
[Trait("Intent", "Safety")]
[Trait("Category", "Unit")]
public void Signer_RejectsExpiredCertificate()
{
// Test that expired certificates are rejected (safety invariant)
}
[Trait("Intent", "Regulatory")]
[Trait("Category", "Integration")]
public void EvidenceBundle_IsImmutableAfterSigning()
{
// Test that signed evidence cannot be modified (audit requirement)
}
```
**Enforcement:**
- Tests without intent tags in regulatory modules (Policy, Authority, Signer, Attestor, EvidenceLocker) will trigger CI warnings.
- Intent coverage metrics are tracked per module in TEST_COVERAGE_MATRIX.md.
---
## Observability contract testing (Turn #6)
Logs, metrics, and traces are APIs. WebService tests (W1 model) must validate observability contracts.
**OTel trace contracts:**
- Required spans must exist for core operations.
- Span attributes must include required fields (correlation ID, tenant ID where applicable).
- Attribute cardinality must be bounded (no unbounded label explosion).
**Structured log contracts:**
- Required fields must be present (timestamp, level, message, correlation ID).
- No PII in logs (validated via pattern matching).
- Log levels must be appropriate (no ERROR for expected conditions).
**Metrics contracts:**
- Required metrics must exist for core operations.
- Label cardinality must be bounded (< 100 distinct values per label).
- Counters must be monotonic.
**Usage:**
```csharp
using var otel = new OtelCapture();
await sut.ProcessAsync(request);
OTelContractAssert.HasRequiredSpans(otel, "ProcessRequest", "ValidateInput", "PersistResult");
OTelContractAssert.SpanHasAttributes(otel.GetSpan("ProcessRequest"), "corr_id", "tenant_id");
OTelContractAssert.NoHighCardinalityAttributes(otel, threshold: 100);
```
---
## Evidence traceability (Turn #6)
Every critical behavior must link: requirement -> test -> run -> artifact -> deployed version. This chain enables audit and root cause analysis.
**Requirement linking:**
```csharp
[Requirement("REQ-EVIDENCE-001", SprintTaskId = "TEST-ENH6-06")]
[Trait("Intent", "Regulatory")]
public void EvidenceChain_IsComplete()
{
// Test that evidence chain is traceable
}
```
**Artifact immutability:**
- Tests for compliance-critical artifacts must verify hash stability.
- Use `EvidenceChainAssert.ArtifactImmutable()` for determinism verification.
**Traceability reporting:**
- CI generates traceability matrix linking requirements to tests to artifacts.
- Orphaned tests (no requirement reference) in regulatory modules trigger warnings.
---
## Cross-version and environment testing (Turn #6)
Integration tests must validate interoperability across versions and environments.
**Cross-version testing (Interop):**
- N-1 compatibility: current service must work with previous schema/API version.
- N+1 compatibility: previous service must work with current schema/API version.
- Run before releases to prevent breaking changes.
**Environment skew testing:**
- Run integration tests across varied infrastructure profiles.
- Profiles: standard, high-latency (100ms), low-bandwidth (10 Mbps), packet-loss (1%).
- Assert result equivalence across profiles.
**Usage:**
```csharp
[Trait("Category", "Interop")]
public async Task SchemaV2_CompatibleWithV1Client()
{
await using var v1Client = await fixture.StartVersion("v1.0.0", "EvidenceLocker");
await using var v2Server = await fixture.StartVersion("v2.0.0", "EvidenceLocker");
var result = await fixture.TestHandshake(v1Client, v2Server);
Assert.True(result.IsCompatible);
}
```
---
## Time-extended and post-incident testing (Turn #6)
Long-running tests surface issues that only emerge over time. Post-incident tests prevent recurrence.
**Time-extended (longevity) tests:**
- Run E2E scenarios continuously for hours to detect memory leaks, counter drift, quota exhaustion.
- Verify memory returns to baseline after sustained load.
- Verify connection pools do not leak under sustained load.
- Run nightly; release-gating for critical modules.
**Post-incident replay tests:**
- Every production incident (P1/P2) produces a permanent E2E regression test.
- Test derived from replay manifest capturing exact event sequence.
- Test includes incident metadata (ID, root cause, severity).
- Tests tagged with `[Trait("Category", "PostIncident")]`.
**Usage:**
```csharp
[Trait("Category", "Longevity")]
[Trait("Intent", "Operational")]
public async Task ScannerWorker_NoMemoryLeakUnderLoad()
{
var runner = new StabilityTestRunner();
await runner.RunExtended(
scenario: () => ProcessScanBatch(),
duration: TimeSpan.FromHours(1),
metrics: new StabilityMetrics(),
ct: CancellationToken.None);
var report = runner.GenerateReport();
Assert.True(report.MemoryGrowthRate < 0.01, "Memory growth rate exceeds threshold");
}
```

# Sprint 0127 · OCI Referrer Bundle Export (Critical Gap Closure)
## Topic & Scope
- **Critical gap**: Mirror bundle and offline kit exports do NOT discover or include OCI referrer artifacts (SBOMs, attestations, signatures) linked to images via the OCI 1.1 referrers API.
- Integrate existing `OciReferrerDiscovery` infrastructure into `MirrorAdapter`, `MirrorBundleBuilder`, and `OfflineKitPackager` flows.
- Ensure `ImportValidator` verifies referrer artifacts are present for each subject image.
- Support fallback tag-based discovery for registries without OCI 1.1 API (e.g., GHCR).
- **Working directory:** `src/ExportCenter/`, `src/AirGap/`
- **Expected evidence:** Unit tests, integration tests with Testcontainers, deterministic bundle output verification.
## Dependencies & Concurrency
- Upstream: `OciReferrerDiscovery` and `OciReferrerFallback` already implemented in `src/ExportCenter/.../Distribution/Oci/`.
- No blocking dependencies; can proceed immediately.
- Concurrency: Tasks 1-3 can proceed in parallel; Task 4-6 depend on 1-3.
## Documentation Prerequisites
- `docs/modules/export-center/architecture.md` (update with referrer discovery flow)
- `docs/modules/airgap/guides/offline-bundle-format.md` (update bundle structure)
- Advisory source: OCI v1.1 referrers API specification and registry compatibility matrix.

## Delivery Tracker
### REF-EXPORT-01 - Add Referrer Discovery to MirrorAdapter
Status: DONE
Dependency: None
Owners: ExportCenter Guild
Task description:
Modify `MirrorAdapter.CollectDataSourcesAsync()` to detect image references in items and automatically discover their OCI referrer artifacts.
For each item that represents a container image (identifiable by digest pattern `sha256:*` or image reference format):
1. Call `OciReferrerDiscovery.ListReferrersAsync()` with the image digest
2. If referrers API returns 404/empty, call `OciReferrerFallback.DiscoverViaTagsAsync()` to check for `sha256-{digest}.*` tags
3. For each discovered referrer (SBOM, attestation, signature, VEX), fetch the artifact content
4. Add discovered artifacts to the data sources list with appropriate `MirrorBundleDataCategory`
Inject `IOciReferrerDiscovery` and `IOciReferrerFallback` via DI into `MirrorAdapter`.
Handle errors gracefully: if referrer discovery fails for a single image, log warning and continue with other images.
Implementation completed:
- Created `IReferrerDiscoveryService` interface in Core with `DiscoverReferrersAsync` and `GetReferrerContentAsync`
- Created `ReferrerDiscoveryResult`, `DiscoveredReferrer`, `ReferrerLayer` models

## Decisions & Risks
| Item | Status / Decision | Notes |
| --- | --- | --- |
| Critical gap confirmation | CONFIRMED | `MirrorAdapter` does not call `OciReferrerDiscovery`; artifacts silently dropped. |
| Referrer storage structure | PROPOSED | `referrers/{subject-digest}/` hierarchy; to be confirmed during implementation. |
| Fallback tag pattern | USE EXISTING | `sha256-{digest}.*` pattern already in `OciReferrerFallback`. |
### Risk table
| Risk | Severity | Mitigation / Owner |
| --- | --- | --- |
| Referrer discovery significantly increases export time | Medium | Add parallelism, cache registry probes; measure in integration tests. |
| Large referrer artifacts bloat bundles | Medium | Add size limits/warnings; document recommended max sizes. |
| Fallback tag discovery misses artifacts | Low | Comprehensive testing with GHCR-like behavior. |
## Next Checkpoints
| Date (UTC) | Session / Owner | Target outcome | Fallback / Escalation |
| --- | --- | --- | --- |
| 2026-02-03 | REF-EXPORT-01/02/03 completion | Core referrer discovery and bundle integration complete. | If blocked, escalate registry access issues. |
| 2026-02-07 | REF-EXPORT-04/05 completion | Validation and capability probing complete. | Defer non-critical enhancements if needed. |
| 2026-02-10 | Sprint completion + docs | All tasks DONE, documentation updated. | Archive sprint; carry forward any blockers. |

## OCI Referrer Artifacts
Mirror bundles automatically include OCI referrer artifacts (SBOMs, attestations, signatures) discovered from container registries. These artifacts are stored under a dedicated `referrers/` directory keyed by subject image digest.
### Referrer Directory Structure
```
bundle.stella.bundle.tgz
├── ...existing structure...
├── referrers/
│ └── sha256-abc123.../ # Subject image digest
│ ├── sha256-def456.json # CycloneDX SBOM
│ ├── sha256-ghi789.json # in-toto attestation
│ └── sha256-jkl012.json # VEX statement
└── indexes/
├── referrers.index.json # Referrer artifact index
└── attestations.index.json # Attestation cross-reference
```
### Manifest Referrers Section
The bundle manifest includes a `referrers` section documenting all discovered artifacts:
```yaml
referrers:
subjects:
- subject: "sha256:abc123..."
artifacts:
- digest: "sha256:def456..."
artifactType: "application/vnd.cyclonedx+json"
mediaType: "application/vnd.oci.image.manifest.v1+json"
size: 12345
path: "referrers/sha256-abc123.../sha256-def456.json"
sha256: "def456789..."
category: "sbom"
annotations:
org.opencontainers.image.created: "2026-01-27T10:00:00Z"
- digest: "sha256:ghi789..."
artifactType: "application/vnd.in-toto+json"
mediaType: "application/vnd.oci.image.manifest.v1+json"
size: 8192
path: "referrers/sha256-abc123.../sha256-ghi789.json"
sha256: "ghi789abc..."
category: "attestation"
```
### Referrer Validation
The `ImportValidator` verifies referrer artifacts during bundle import:
| Validation | Severity | Description |
|------------|----------|-------------|
| `ReferrerMissing` | Error | Declared artifact not found in bundle |
| `ReferrerChecksumMismatch` | Error | SHA-256 doesn't match declared value |
| `ReferrerSizeMismatch` | Error | Size doesn't match declared value |
| `OrphanedReferrer` | Warning | File exists in `referrers/` but not declared |
### Artifact Types
| Artifact Type | Category | Description |
|---------------|----------|-------------|
| `application/vnd.cyclonedx+json` | `sbom` | CycloneDX SBOM |
| `application/vnd.spdx+json` | `sbom` | SPDX SBOM |
| `application/vnd.openvex+json` | `vex` | OpenVEX statement |
| `application/vnd.csaf+json` | `vex` | CSAF advisory |
| `application/vnd.in-toto+json` | `attestation` | in-toto attestation |
| `application/vnd.dsse.envelope+json` | `attestation` | DSSE envelope |
| `application/vnd.slsa.provenance+json` | `attestation` | SLSA provenance |
| `application/vnd.stella.rva+json` | `attestation` | RVA attestation |
### Registry Compatibility
Referrer discovery supports both OCI 1.1 native API and fallback tag-based discovery:
- **OCI 1.1+**: Uses native `/v2/{repo}/referrers/{digest}` endpoint
- **OCI 1.0 (fallback)**: Discovers via `sha256-{digest}.*` tag pattern
See [Registry Compatibility Matrix](../../export-center/registry-compatibility.md) for per-registry details.
## Function Map Artifacts
Bundles can include runtime linkage verification artifacts. These are stored in dedicated subdirectories:

```
## 3) Built-in Plugins
### IntegrationPlugin
Validates external system connectivity and capabilities.
**Check Catalog:**
| Check ID | Name | Severity | Description |
|----------|------|----------|-------------|
| `check.integration.oci.credentials` | OCI Registry Credentials | Fail | Validate registry authentication |
| `check.integration.oci.pull` | OCI Registry Pull Authorization | Fail | Verify pull permissions |

| `check.integration.oci.referrers` | OCI Registry Referrers API | Warn | Check OCI 1.1 referrers support |
| `check.integration.oci.capabilities` | OCI Registry Capability Matrix | Info | Probe all registry capabilities |
See [Registry Diagnostic Checks](./registry-checks.md) for detailed documentation.
### ConfigurationPlugin
Validates platform configuration.
| Check ID | Name | Severity | Description |
|----------|------|----------|-------------|
| `check.config.database` | Database Connection | Fail | Verify database connectivity |
| `check.config.secrets` | Secrets Provider | Fail | Verify secrets access |
| `check.config.tls` | TLS Configuration | Warn | Validate TLS certificates |
### HealthPlugin

| Check ID | Name | Severity | Description |
|----------|------|----------|-------------|
| `check.health.api` | API Health | Fail | Verify API endpoints |
| `check.health.worker` | Worker Health | Fail | Verify background workers |
| `check.health.storage` | Storage Health | Fail | Verify storage backends |
## 4) Check Patterns
### Non-Destructive Probing
Registry checks use non-destructive operations:
```csharp
// Pull check: HEAD request only (no data transfer)
var response = await client.SendAsync(new HttpRequestMessage(HttpMethod.Head, manifestUrl), ct);
// Push check: Start upload then immediately cancel
var uploadResponse = await client.PostAsync(uploadsUrl, null, ct);
if (uploadResponse.StatusCode == HttpStatusCode.Accepted)
{
var location = uploadResponse.Headers.Location;
await client.DeleteAsync(location, ct); // Cancel upload
}
```
### Capability Detection
Registry capability probing sequence:
```
1. GET /v2/ → Extract OCI-Distribution-API-Version header
2. GET /v2/{repo}/referrers/{digest} → Check referrers API support
3. POST /v2/{repo}/blobs/uploads/ → Check chunked upload support
└─ DELETE {location} → Cancel upload session
4. POST /v2/{repo}/blobs/uploads/?mount=...&from=... → Check cross-repo mount
5. OPTIONS /v2/{repo}/manifests/{ref} → Check delete support (Allow header)
6. OPTIONS /v2/{repo}/blobs/{digest} → Check blob delete support
```
### Evidence Collection
All checks collect structured evidence:
```csharp
var result = CheckResultBuilder.Create(check)
.Pass("Registry authentication successful")
.WithEvidence(eb => eb
.Add("registry_url", registryUrl)
.Add("auth_method", "bearer")
.Add("response_time_ms", elapsed.TotalMilliseconds.ToString("F0"))
.AddSensitive("token_preview", RedactToken(token)))
.Build();
```
### Credential Redaction
Sensitive values are automatically redacted:
```csharp
// Redact to first 2 + last 2 characters
private static string Redact(string? value)
{
if (string.IsNullOrEmpty(value) || value.Length <= 4)
return "****";
return $"{value[..2]}...{value[^2..]}";
}
// "mysecretpassword" → "my...rd"
```
## 5) CLI Integration
```bash
# Run all checks
stella doctor
# Run checks by tag
stella doctor --tag registry
stella doctor --tag configuration
# Run specific check
stella doctor --check check.integration.oci.referrers
# Output formats
stella doctor --format table # Default: human-readable
stella doctor --format json # Machine-readable
stella doctor --format sarif # SARIF for CI integration
# Verbosity
stella doctor --verbose # Include evidence details
stella doctor --quiet # Only show failures
# Filtering by severity
stella doctor --min-severity warn # Skip info/pass
```
## 6) Extensibility
### Creating a Custom Check
```csharp
public sealed class MyCustomCheck : IDoctorCheck
{
public string CheckId => "check.custom.mycheck";
public string Name => "My Custom Check";
public string Description => "Validates custom integration";
public DoctorSeverity DefaultSeverity => DoctorSeverity.Fail;
public IReadOnlyList<string> Tags => ["custom", "integration"];
public TimeSpan EstimatedDuration => TimeSpan.FromSeconds(5);
public bool CanRun(DoctorPluginContext context)
{
// Return false if preconditions not met
return context.Configuration["Custom:Enabled"] == "true";
}
public async Task<CheckResult> RunAsync(DoctorPluginContext context, CancellationToken ct)
{
var builder = CheckResultBuilder.Create(this);
try
{
// Perform check logic
var result = await ValidateAsync(context, ct);
if (result.Success)
{
return builder
.Pass("Custom validation successful")
.WithEvidence(eb => eb.Add("detail", result.Detail))
.Build();
}
return builder
.Fail("Custom validation failed")
.WithLikelyCause("Configuration is invalid")
.WithRemediation(rb => rb
.AddManualStep(1, "Check configuration", "Verify Custom:Setting is correct")
.WithRunbookUrl("https://docs.stella-ops.org/runbooks/custom-check"))
.Build();
}
catch (Exception ex)
{
return builder
.Fail($"Check failed with error: {ex.Message}")
.WithEvidence(eb => eb.Add("exception_type", ex.GetType().Name))
.Build();
}
}
}
```
### Creating a Custom Plugin
```csharp
public sealed class MyCustomPlugin : IDoctorPlugin
{
public string PluginId => "custom";
public string DisplayName => "Custom Checks";
public string Category => "Integration";
public Version Version => new(1, 0, 0);
public IEnumerable<IDoctorCheck> GetChecks()
{
yield return new MyCustomCheck();
yield return new AnotherCustomCheck();
}
public Task InitializeAsync(DoctorPluginContext context, CancellationToken ct)
{
// Optional initialization
return Task.CompletedTask;
}
}
```
## 7) Telemetry
Doctor emits metrics and traces for observability:
**Metrics:**
- `doctor_check_duration_seconds{check_id, severity}` - Check execution time
- `doctor_check_results_total{check_id, severity}` - Result counts
- `doctor_plugin_load_duration_seconds{plugin_id}` - Plugin initialization time
**Traces:**
- `doctor.run` - Full doctor run span
- `doctor.check.{check_id}` - Individual check spans with evidence as attributes

# Registry Diagnostic Checks
> Module: Doctor
> Plugin: IntegrationPlugin
> Sprint: SPRINT_0127_001_0002_oci_registry_compatibility
This document covers the OCI registry diagnostic checks available in Stella Doctor for validating registry connectivity, capabilities, and authorization.
## Overview
StellaOps Doctor includes comprehensive registry diagnostics to verify that configured OCI registries are properly accessible and support the features required for secure software supply chain operations. These checks are part of the `IntegrationPlugin` and can be run individually or as a group using the `registry` tag.
## Quick Start
```bash
# Run all registry checks
stella doctor --tag registry
# Run a specific check
stella doctor --check check.integration.oci.referrers
# Export results as JSON
stella doctor --tag registry --format json --output registry-health.json
# Run with verbose output
stella doctor --tag registry --verbose
```
## Available Checks
### check.integration.oci.credentials
**Purpose:** Validate registry credential configuration and authentication.
| Property | Value |
|----------|-------|
| Name | OCI Registry Credentials |
| Default Severity | Fail |
| Tags | `registry`, `oci`, `credentials`, `secrets`, `auth` |
| Estimated Duration | 5 seconds |
**What it checks:**
1. Credential configuration (username/password, bearer token, or anonymous)
2. Authentication against the `/v2/` endpoint
3. OAuth2 token exchange for registries requiring it
4. Credential validity and format
**Evidence collected:**
- `registry_url` - Target registry URL
- `auth_method` - Authentication method (basic, bearer, anonymous)
- `username` - Username (if configured)
- `credentials_valid` - Whether authentication succeeded
- `auth_challenge` - WWW-Authenticate header if present
**Pass criteria:**
- Credentials are properly configured
- Authentication succeeds against `/v2/` endpoint
**Fail scenarios:**
- Missing required credentials (username without password)
- Invalid credentials (401 Unauthorized)
- Network or TLS errors
---
### check.integration.oci.pull
**Purpose:** Verify pull authorization for the configured test repository.
| Property | Value |
|----------|-------|
| Name | OCI Registry Pull Authorization |
| Default Severity | Fail |
| Tags | `registry`, `oci`, `pull`, `authorization` |
| Estimated Duration | 5 seconds |
**What it checks:**
1. HEAD request to manifest endpoint (non-destructive)
2. Authorization for pull operations
3. Image/tag existence
**Evidence collected:**
- `registry_url` - Target registry URL
- `test_repository` - Repository used for testing
- `test_tag` - Tag used for testing
- `pull_authorized` - Whether pull is authorized
- `manifest_digest` - Manifest digest if successful
- `http_status` - HTTP status code
**Pass criteria:**
- HEAD request to manifest returns 200 OK
- Manifest digest is returned
**Fail scenarios:**
- 401 Unauthorized: Invalid credentials
- 403 Forbidden: Valid credentials but no pull permission
- Info (not fail) for 404: Test image not found (can't verify)
---
### check.integration.oci.push
**Purpose:** Verify push authorization for the configured test repository.
| Property | Value |
|----------|-------|
| Name | OCI Registry Push Authorization |
| Default Severity | Fail |
| Tags | `registry`, `oci`, `push`, `authorization` |
| Estimated Duration | 10 seconds |
**What it checks:**
1. Initiates blob upload via POST (non-destructive)
2. Immediately cancels the upload session
3. Verifies push authorization
**Evidence collected:**
- `registry_url` - Target registry URL
- `test_repository` - Repository used for testing
- `push_authorized` - Whether push is authorized
- `upload_session_cancelled` - Whether cleanup succeeded
- `http_status` - HTTP status code
- `credentials_valid` - Whether credentials are valid (for 403)
**Pass criteria:**
- POST to blob uploads returns 202 Accepted
- Upload session is successfully cancelled
**Fail scenarios:**
- 401 Unauthorized: Invalid credentials
- 403 Forbidden: Valid credentials but no push permission
**Non-destructive design:**
This check initiates a blob upload session but immediately cancels it via DELETE. No data is actually pushed to the registry.
---
### check.integration.oci.referrers
**Purpose:** Verify OCI 1.1 referrers API support for artifact linking.
| Property | Value |
|----------|-------|
| Name | OCI Registry Referrers API Support |
| Default Severity | Warn |
| Tags | `registry`, `oci`, `referrers`, `oci-1.1` |
| Estimated Duration | 10 seconds |
**What it checks:**
1. Resolves manifest digest for test image
2. Probes the referrers API endpoint
3. Determines if native API or fallback is required
**Evidence collected:**
- `registry_url` - Target registry URL
- `referrers_supported` - Whether referrers API is supported
- `fallback_required` - Whether tag-based fallback is needed
- `oci_version` - OCI-Distribution-API-Version header
- `referrers_count` - Number of referrers found (if any)
**Pass criteria:**
- Referrers endpoint returns 200 OK with OCI index
- Or returns 404 with OCI index content (empty referrers)
**Warn scenarios (not Fail):**
- 404 without OCI index: API not supported, fallback required
- 405 Method Not Allowed: API not implemented
The severity is Warn (not Fail) because StellaOps automatically uses tag-based fallback discovery when the referrers API is unavailable.
---
### check.integration.oci.capabilities
**Purpose:** Comprehensive registry capability matrix detection.
| Property | Value |
|----------|-------|
| Name | OCI Registry Capability Matrix |

2. Referrers API support
3. Chunked upload support
4. Cross-repository blob mounting
5. Manifest delete support
6. Blob delete support
**Evidence collected:**
- `registry_url` - Target registry URL
- `distribution_version` - OCI/Docker distribution version
- `supports_referrers_api` - true/false/unknown
- `supports_chunked_upload` - true/false/unknown
- `supports_cross_repo_mount` - true/false/unknown
- `supports_manifest_delete` - true/false/unknown
- `supports_blob_delete` - true/false/unknown
- `capability_score` - Summary (e.g., "5/6")
**Severity logic:**
- Pass: All capabilities supported
- Info: Some non-critical capabilities missing
- Warn: Referrers API not supported (critical for StellaOps)
---
## Configuration
Registry checks use the following configuration keys:
```yaml
OCI:
RegistryUrl: "https://registry.example.com"
Username: "service-account"
Password: "secret" # Or use PasswordSecretRef
Token: "bearer-token" # Alternative to username/password
TestRepository: "stellaops/test" # Default: library/alpine
TestTag: "latest" # Default: latest
```
### Environment Variables
```bash
export OCI__RegistryUrl="https://registry.example.com"
export OCI__Username="service-account"
export OCI__Password="secret"
export OCI__TestRepository="stellaops/test"
export OCI__TestTag="latest"
```
## Registry Compatibility Matrix
| Registry | Version | Referrers API | Chunked Upload | Cross-Mount | Delete | Recommended |
|----------|---------|---------------|----------------|-------------|--------|-------------|
| **ACR** | Any | Native | Yes | Yes | Yes | Yes |
| **ECR** | Any | Native | Yes | Yes | Yes | Yes |
| **GCR/Artifact Registry** | Any | Native | Yes | Yes | Yes | Yes |
| **Harbor** | 2.6+ | Native | Yes | Yes | Yes | Yes |
| **Quay** | 3.12+ | Native | Yes | Yes | Yes | Yes |
| **JFrog Artifactory** | 7.x+ | Native | Yes | Yes | Yes | Yes |
| **GHCR** | Any | Fallback | Yes | Yes | Yes | With fallback |
| **Docker Hub** | Any | Fallback | Yes | Limited | Limited | With fallback |
| **registry:2** | 2.8+ | Fallback | Yes | Yes | Yes | For testing |
| **Zot** | Any | Native | Yes | Yes | Yes | Yes |
| **Distribution** | Edge | Partial | Yes | Yes | Yes | Yes |
### Legend
- **Native**: Full OCI 1.1 referrers API support
- **Fallback**: Requires tag-based discovery (`sha256-{digest}.*` tags)
- **Partial**: Support varies by configuration
## Known Issues & Workarounds
### GHCR (GitHub Container Registry)
**Issue:** Referrers API not implemented (returns 404 without OCI index)
**Impact:** Slower artifact discovery, requires tag-based fallback
**Workaround:** StellaOps automatically detects this and uses fallback discovery. No action required.
**Tracking:** GitHub feature request pending
### Docker Hub
**Issue:** Rate limiting can affect capability probes
**Impact:** Probes may timeout or return 429
**Workaround:**
- Use authenticated requests to increase rate limits
- Configure retry with exponential backoff
- Consider using a pull-through cache
### Harbor < 2.6
**Issue:** Referrers API not available in older versions
**Impact:** Requires tag-based fallback
**Workaround:** Upgrade to Harbor 2.6+ for native referrers API support
### ACR with CMK Encryption
**Issue:** Customer-managed key encrypted registries may use tag fallback
**Impact:** Slightly slower referrer discovery
**Workaround:** Automatic fallback detection handles this transparently
**Reference:** [Azure Container Registry CMK Documentation](https://learn.microsoft.com/azure/container-registry/)
## Interpreting Results
### Healthy Registry Output
```
Registry Checks Summary
=======================
check.integration.oci.credentials PASS Credentials valid for registry.example.com
check.integration.oci.pull PASS Pull authorized (sha256:abc123...)
check.integration.oci.push PASS Push authorization verified
check.integration.oci.referrers PASS Referrers API supported (OCI 1.1)
check.integration.oci.capabilities PASS Full capability support (6/6)
Overall: 5 passed, 0 warnings, 0 failures
```
### Registry with Fallback Required
```
Registry Checks Summary
=======================
check.integration.oci.credentials PASS Credentials valid for ghcr.io
check.integration.oci.pull PASS Pull authorized (sha256:def456...)
check.integration.oci.push PASS Push authorization verified
check.integration.oci.referrers WARN Referrers API not supported (using fallback)
check.integration.oci.capabilities INFO Partial capability support (4/6)
Overall: 3 passed, 1 warning, 1 info, 0 failures
Recommendations:
- Referrers API: StellaOps will use tag-based fallback automatically
- Consider upgrading to a registry with OCI 1.1 support for better performance
```
## Remediation Steps
### Invalid Credentials (401)
1. Verify username and password are correct
2. Check if credentials have expired
3. For OAuth2 registries, ensure token refresh is working
4. Test with docker CLI: `docker login <registry>`
### No Permission (403)
1. Verify the service account has required permissions
2. For pull: Reader/Viewer role is typically sufficient
3. For push: Contributor/Writer role is required
4. Check repository-level permissions (some registries have repo-specific ACLs)
### Referrers API Not Supported
1. Check registry version against compatibility matrix
2. Upgrade registry if possible (Harbor 2.6+, Quay 3.12+)
3. If upgrade not possible, StellaOps will use fallback automatically
4. Monitor for performance impact with large artifact counts
### Network/TLS Errors
1. Verify network connectivity: `curl -v https://<registry>/v2/`
2. Check TLS certificate validity
3. For self-signed certs, configure trust or use `--insecure` (not recommended for production)
4. Check firewall rules and proxy configuration

## OCI Referrer Discovery
Mirror bundles automatically discover and include OCI referrer artifacts (SBOMs, attestations, signatures, VEX statements) linked to container images via the OCI 1.1 referrers API.
### Discovery Flow

```
### Capability Probing
Before starting referrer discovery, the export flow probes each unique registry to determine capabilities:
- **OCI 1.1+ registries**: Native referrers API (`/v2/{repo}/referrers/{digest}`)
- **OCI 1.0 registries**: Fallback to tag-based discovery (`sha256-{digest}.*` tags)
Capabilities are cached per registry host with a 1-hour TTL.
**Logging at export start:**
```
[INFO] Probing 3 registries for OCI referrer capabilities before export
[INFO] Registry registry.example.com: OCI 1.1 (referrers API supported, version=OCI-Distribution/2.1, probe_ms=42)
[WARN] Registry ghcr.io: OCI 1.0 (using fallback tag discovery, version=registry/2.0, probe_ms=85)
```
### Telemetry Metrics
| Metric | Description | Tags |
|--------|-------------|------|
| `export_registry_capabilities_probed_total` | Registry capability probe operations | `registry`, `api_supported` |
| `export_referrer_discovery_method_total` | Discovery operations by method | `registry`, `method` (native/fallback) |
| `export_referrers_discovered_total` | Referrers discovered | `registry`, `artifact_type` |
| `export_referrer_discovery_failures_total` | Discovery failures | `registry`, `error_type` |
### Artifact Type Mapping
| OCI Artifact Type | Bundle Category | Example |
|-------------------|-----------------|---------|
| `application/vnd.cyclonedx+json` | `sbom` | CycloneDX SBOM |
| `application/vnd.spdx+json` | `sbom` | SPDX SBOM |
| `application/vnd.openvex+json` | `vex` | OpenVEX statement |
| `application/vnd.csaf+json` | `vex` | CSAF document |
| `application/vnd.in-toto+json` | `attestation` | in-toto attestation |
| `application/vnd.dsse.envelope+json` | `attestation` | DSSE envelope |
| `application/vnd.slsa.provenance+json` | `attestation` | SLSA provenance |
### Error Handling
- If referrer discovery fails for a single image, the export logs a warning and continues with other images
- Network failures do not block the entire export
- Missing referrer artifacts are validated during bundle import (see [ImportValidator](../airgap/guides/offline-bundle-format.md))

## Distribution flows
- **HTTP download.** Console and CLI stream bundles via chunked transfer; supports range requests and resumable downloads. Response includes `X-Export-Digest`, `X-Export-Length`, and optional encryption metadata.
- **OCI push.** Worker uses ORAS to publish bundles as OCI artefacts with annotations describing profile, tenant, manifest digest, and provenance reference. Supports multi-tenant registries with `repository-per-tenant` naming.

### Native Referrers API (OCI 1.1)
The preferred method queries the registry referrers endpoint directly:
### Fallback Tag-Schema Discovery
For registries without OCI 1.1 support, tags following the pattern are enumerated:
Each matching tag is then resolved to get artifact metadata.
## Troubleshooting
### Common Issues
| Issue | Registry | Solution |
|-------|----------|----------|
| 404 on referrers endpoint | GHCR, Distribution | Use fallback tag discovery |
| Rate limit exceeded | Docker Hub | Authenticate or reduce concurrency |
| Permission denied | ECR, ACR | Check IAM/RBAC permissions |
| No referrers found | All | Verify artifacts were pushed with referrer relationship |
| Timeout | All | Increase timeout_seconds, check network |

# eBPF Reachability Evidence System
This documentation covers the eBPF-based runtime reachability evidence collection system in StellaOps.
## Overview
The eBPF reachability system provides kernel-level syscall tracing to prove which code paths, files, and network connections were (or weren't) executed in production. This evidence complements static analysis by providing runtime proof of actual behavior.
## Key Capabilities
- **Syscall Tracing**: Capture file access (`openat`), process execution (`exec`), and network connections (`inet_sock_set_state`)
- **User-Space Probes**: Monitor libc network functions and OpenSSL TLS operations
- **Container Awareness**: Automatic correlation of events to container IDs and image digests
- **Signed Evidence Chains**: DSSE-signed chunks with Rekor transparency log integration
- **Deterministic Output**: Canonical NDJSON format for reproducible evidence
## Quick Start
### Prerequisites
- Linux kernel 5.x+ with BTF support (4.14+ with external BTF)
- Container runtime (containerd, Docker, or CRI-O)
- StellaOps CLI installed
### Enable Runtime Evidence Collection
```bash
# Start the runtime signal collector
stella signals start --target /var/lib/stellaops/evidence
# Verify collection is active
stella signals status
# View recent signals
stella signals inspect sha256:abc123...
# Verify evidence chain integrity
stella signals verify-chain /var/lib/stellaops/evidence
```
### Configuration
```yaml
# stellaops.yaml
signals:
enabled: true
output_directory: /var/lib/stellaops/evidence
rotation:
max_size_mb: 100
max_age_hours: 1
signing:
enabled: true
key_id: fulcio # or KMS key reference
submit_to_rekor: true
filters:
target_containers: [] # Empty = all containers
path_allowlist:
- /etc/**
- /var/lib/**
path_denylist:
- /proc/**
- /sys/**
```

# Deployment Guide
## Prerequisites
### Kernel Requirements
**Minimum:** Linux 4.14 with eBPF support
**Recommended:** Linux 5.8+ with BTF and ring buffer support
#### Verify Kernel Configuration
```bash
# Check eBPF support
zcat /proc/config.gz 2>/dev/null | grep -E "CONFIG_BPF|CONFIG_DEBUG_INFO_BTF" || \
cat /boot/config-$(uname -r) | grep -E "CONFIG_BPF|CONFIG_DEBUG_INFO_BTF"
# Required settings:
# CONFIG_BPF=y
# CONFIG_BPF_SYSCALL=y
# CONFIG_BPF_JIT=y (recommended)
# CONFIG_DEBUG_INFO_BTF=y (for CO-RE)
```
#### Verify BTF Availability
```bash
# Check for BTF in kernel
ls -la /sys/kernel/btf/vmlinux
# If missing, check BTFHub or kernel debug packages
```
### Container Runtime
Supported runtimes:
- containerd 1.4+
- Docker 20.10+
- CRI-O 1.20+
Verify cgroup v2 is available (recommended):
```bash
mount | grep cgroup2
# Expected: cgroup2 on /sys/fs/cgroup type cgroup2
```
### Permissions
The collector requires elevated privileges:
**Option 1: Root**
```bash
sudo stella signals start
```
**Option 2: Capabilities (preferred)**
```bash
# Grant required capabilities
sudo setcap cap_bpf,cap_perfmon,cap_sys_ptrace+ep /usr/bin/stella
# Or run with specific capabilities
sudo capsh --caps="cap_bpf,cap_perfmon,cap_sys_ptrace+eip" -- -c "stella signals start"
```
Required capabilities:
- `CAP_BPF`: Load and manage eBPF programs
- `CAP_PERFMON`: Access performance monitoring (ring buffer)
- `CAP_SYS_PTRACE`: Attach uprobes to processes
## Installation
### Standard Installation
```bash
# Install StellaOps CLI
curl -fsSL https://stella.ops/install.sh | bash
# Verify installation
stella version
stella signals --help
```
### Air-Gap Installation
For disconnected environments, use the offline bundle:
```bash
# Download bundle (on connected machine)
stella bundle create --include-probes ebpf-reachability \
--output stellaops-offline.tar.gz
# Transfer to air-gapped system
scp stellaops-offline.tar.gz airgap-host:
# Install on air-gapped system
tar -xzf stellaops-offline.tar.gz
cd stellaops-offline
./install.sh
```
The bundle includes:
- Pre-compiled eBPF probes for common kernel versions
- BTF files for kernels without built-in BTF
- All runtime dependencies
### Pre-Compiled Probes
If CO-RE probes fail to load, use kernel-specific probes:
```bash
# List available pre-compiled probes
stella signals probes list
# Install probes for specific kernel
stella signals probes install --kernel $(uname -r)
# Verify probe compatibility
stella signals probes verify
```
## Configuration
### Basic Configuration
Create `/etc/stellaops/signals.yaml`:
```yaml

output_directory: /var/lib/stellaops/evidence
# Ring buffer size (default 256KB)
ring_buffer_size: 262144
# Maximum events per second (0 = unlimited)
max_events_per_second: 0
# Rotation settings
rotation:
max_size_mb: 100
max_age_hours: 1
# Signing configuration
signing:
enabled: true
key_id: fulcio # or KMS key ARN
submit_to_rekor: true
```
### Probe Selection
Enable specific probes:
```yaml
signals:
probes:
# Tracepoints
sys_enter_openat: true
sched_process_exec: true

# Capture connections to these CIDRs
allowlist:
- 10.0.0.0/8
- 172.16.0.0/12
# Exclude these destinations
denylist:
- 127.0.0.0/8
```
### Resource Limits
Prevent runaway resource usage:
```yaml
signals:
resources:
# Maximum memory for caches
max_cache_memory_mb: 256
# Symbol cache entries
symbol_cache_max_entries: 100000

# eBPF Reachability Architecture
## System Overview
The eBPF reachability system captures kernel-level events to provide cryptographic proof of runtime behavior. It uses Linux eBPF (extended Berkeley Packet Filter) with CO-RE (Compile Once, Run Everywhere) for portable deployment across kernel versions.
## Design Principles
1. **Minimal Kernel Footprint**: eBPF programs perform only essential filtering and data capture
2. **User-Space Enrichment**: Complex lookups (symbols, containers, SBOMs) happen in user space
3. **Deterministic Output**: Same inputs produce byte-identical NDJSON output
4. **Chain of Custody**: Every evidence chunk is cryptographically signed and linked
## Component Architecture
### Kernel-Space Components
#### Ring Buffer (`BPF_MAP_TYPE_RINGBUF`)
- Single shared buffer for all event types (default 256KB)
- Lock-free, multi-producer design
- Automatic backpressure via `bpf_ringbuf_reserve()` failures
#### Tracepoint Probes
| Probe | Event Type | Purpose |
|-------|------------|---------|
| `tracepoint/syscalls/sys_enter_openat` | File access | Track which files are opened |
| `tracepoint/sched/sched_process_exec` | Process execution | Track binary invocations |
| `tracepoint/sock/inet_sock_set_state` | TCP state | Track network connections |
#### Uprobe Probes
| Probe | Library | Purpose |
|-------|---------|---------|
| `uprobe/libc.so:connect` | glibc/musl | Outbound network connections |
| `uprobe/libc.so:accept` | glibc/musl | Inbound connections |
| `uprobe/libssl.so:SSL_read` | OpenSSL | TLS traffic monitoring |
| `uprobe/libssl.so:SSL_write` | OpenSSL | TLS traffic monitoring |
#### BPF Maps for Filtering
```c
// Cgroup filter for container targeting
struct {
__uint(type, BPF_MAP_TYPE_HASH);
__uint(max_entries, 1024);
__type(key, u64); // cgroup_id
__type(value, u8); // 1 = include
} cgroup_filter SEC(".maps");
// Namespace filter for multi-tenant isolation
struct {
__uint(type, BPF_MAP_TYPE_HASH);
__uint(max_entries, 256);
__type(key, u64); // namespace inode
__type(value, u8); // 1 = include
} namespace_filter SEC(".maps");
```
### User-Space Components
#### CoreProbeLoader
Manages eBPF program lifecycle:
- Loads compiled `.bpf.o` files via libbpf
- Attaches probes to tracepoints/uprobes
- Configures BPF maps for filtering
- Handles graceful detachment and cleanup
#### EventParser
Parses binary events from ring buffer:
- Fixed-size header with event type discriminator
- Type-specific payload parsing
- Timestamp normalization (boot time to wall clock)
#### CgroupContainerResolver
Maps kernel cgroup IDs to container identities:
- Parses `/proc/{pid}/cgroup` for container runtime paths
- Supports containerd, Docker, CRI-O path formats
- Caches mappings with configurable TTL
#### EnhancedSymbolResolver
Resolves addresses to human-readable symbols:
- Parses `/proc/{pid}/maps` for ASLR offsets
- Reads ELF symbol tables (`.symtab`, `.dynsym`)
- Optional DWARF debug info for line numbers
- LRU cache with bounded memory usage
#### RuntimeEventEnricher
Decorates events with container and SBOM metadata:
- Container ID and image digest correlation
- SBOM component (PURL) lookup
- Graceful degradation on missing metadata
#### RuntimeEvidenceNdjsonWriter
Produces deterministic NDJSON output:
- Canonical JSON serialization (sorted keys, no whitespace variance)
- Rolling BLAKE3 hash for content verification
- Size and time-based rotation with callbacks
#### EvidenceChunkFinalizer
Signs and links evidence chunks:
- Creates in-toto statements with chunk metadata
- Requests DSSE signatures via Signer service
- Submits to Rekor transparency log
- Maintains chain state (previous_chunk_id linkage)
## Data Flow
```
1. Kernel Event
│
├─► Tracepoint/Uprobe fires
│ └─► BPF program captures event data
│ └─► Filter by cgroup/namespace (optional)
│ └─► Submit to ring buffer
│
2. Ring Buffer Drain
│
├─► EventParser reads binary data
│ └─► Deserialize to typed event struct
│ └─► Validate event integrity
│
3. Resolution & Enrichment
│
├─► CgroupResolver: cgroup_id → container_id
├─► SymbolResolver: address → symbol name
├─► StateProvider: container_id → image_ref
├─► DigestResolver: image_ref → image_digest
└─► SbomProvider: image_digest → purls[]
│
4. Serialization
│
├─► RuntimeEvidenceNdjsonWriter
│ ├─► Canonical JSON serialization
│ ├─► Append to current chunk file
│ └─► Update rolling hash
│
5. Rotation & Signing
│
├─► Size/time threshold reached
│ └─► Close current chunk
│ └─► ChunkFinalizer
│ ├─► Create in-toto statement
│ ├─► Sign with DSSE
│ ├─► Submit to Rekor
│ └─► Link to previous chunk
│
6. Verification
│
└─► stella signals verify-chain
├─► Parse DSSE envelopes
├─► Verify signatures
├─► Check chain linkage
└─► Validate time monotonicity
```
## Performance Characteristics
### Kernel-Space
- Ring buffer prevents event loss under load (backpressure)
- In-kernel filtering reduces user-space processing
- BTF enables zero-copy field access
### User-Space
| Operation | Target Latency |
|-----------|---------------|
| Cached symbol lookup | < 1ms p99 |
| Uncached symbol lookup | < 10ms p99 |
| Container enrichment | < 10ms p99 |
| NDJSON write | < 1ms p99 |
### Throughput
- Target: 100,000 events/second sustained
- Rate limiting available for resource-constrained environments
## Memory Budget
| Component | Default | Configurable |
|-----------|---------|--------------|
| Ring buffer | 256 KB | Yes |
| Symbol cache | 100,000 entries | Yes |
| Container cache | 5 min TTL | Yes |
| Write buffer | 64 KB | Yes |
## Failure Modes
### Ring Buffer Overflow
- **Symptom**: Events dropped, warning logged
- **Mitigation**: Increase buffer size or enable rate limiting
### Symbol Resolution Failure
- **Symptom**: Address shown as `addr:0x{hex}`
- **Mitigation**: Ensure debug symbols available or accept address-only evidence
### Container Resolution Failure
- **Symptom**: `container_id = "unknown:{cgroup_id}"`
- **Mitigation**: Verify Zastava integration, check cgroup path format support
### Signing Failure
- **Symptom**: Chunk saved without signature, warning logged
- **Mitigation**: Check Signer service availability, verify Fulcio/KMS connectivity
## CO-RE (Compile Once, Run Everywhere)
The system uses BTF (BPF Type Format) for kernel-version-independent field access:
```c
// Access kernel struct fields without hardcoded offsets
struct task_struct *task = (void *)bpf_get_current_task();
pid_t pid = BPF_CORE_READ(task, pid);
pid_t tgid = BPF_CORE_READ(task, tgid);
```
**Requirements:**
- Kernel 5.2+ with built-in BTF (recommended)
- Kernel 4.14+ with external BTF from btfhub
## Integration Points
### Zastava (Container State)
- `IContainerIdentityResolver` interface
- Container lifecycle events (start/stop)
- Image reference to digest mapping
### Scanner (Reachability Merger)
- `EbpfSignalMerger` combines runtime with static analysis
- Symbol hash correlation via `RuntimeNodeHash`
### Signer (Evidence Signing)
- `IAttestationSigningService` for DSSE signatures
- `IRekorClient` for transparency log submission
### SBOM Service (Component Correlation)
- `ISbomComponentProvider` for PURL lookup
- Image digest to component mapping

"container_id": "abc123def456",
"image_digest": "sha256:...",
"comm": "nginx",
"event": {
"type": "ssl_op",
"operation": "write",
"requested_bytes": 1024,
"actual_bytes": 1024,
"ssl_ptr": 140234567890
}
}
```
| Field | Type | Description |
|-------|------|-------------|
| `operation` | string | `read` or `write` |
| `requested_bytes` | integer | Bytes requested |
| `actual_bytes` | integer | Bytes actually transferred |
| `ssl_ptr` | integer | SSL context pointer (for correlation) |
### Symbol Call (`symbol_call`)
Captured from function uprobes.
```json
{
"ts_ns": 1234567890123456789,
"src": "uprobe:app:vulnerable_parse_json",
"pid": 1234,
"cgroup_id": 5678,
"container_id": "abc123def456",
"image_digest": "sha256:...",
"comm": "app",
"event": {
"type": "symbol_call",
"symbol": "vulnerable_parse_json",
"library": "/usr/lib/libapp.so",
"offset": 4096,
"address": 140234571986
}
}
```
| Field | Type | Description |
|-------|------|-------------|
| `symbol` | string | Function symbol name |
| `library` | string | Library/binary path |
| `offset` | integer | Offset within library |
| `address` | integer | Runtime address |
## Determinism Requirements
For byte-identical output across runs:
1. **Field Ordering**: All JSON keys sorted alphabetically
2. **Number Format**: Integers as-is, no floating point variance
3. **String Encoding**: UTF-8 with NFC normalization
4. **Null Handling**: Null fields omitted (not `"field": null`)
5. **Whitespace**: No trailing whitespace, single newline per record
## Chunk Metadata
Each evidence chunk includes metadata in its DSSE attestation:
```json
{
"predicateType": "stella.ops/runtime-evidence@v1",
"predicate": {
"chunk_id": "sha256:abc123...",
"chunk_sequence": 42,
"previous_chunk_id": "sha256:def456...",
"event_count": 150000,
"time_range": {
"start": "2026-01-27T10:00:00Z",
"end": "2026-01-27T11:00:00Z"
},
"collector_version": "1.0.0",
"kernel_version": "5.15.0-generic",
"compression": null,
"host_id": "node-01.cluster.local",
"container_ids": ["abc123", "def456"]
}
}
```
## Validation
Evidence can be validated against the JSON Schema:
```bash
# Validate single file
stella evidence validate evidence-chunk-001.ndjson
# Validate and show statistics
stella evidence validate --stats evidence-chunk-001.ndjson
```
## Migration from v0 Schemas
If using earlier per-language schemas, migrate to v1 unified schema:
1. Update field names to snake_case
2. Wrap type-specific fields in `event` object
3. Add `src` field with probe identifier
4. Ensure `ts_ns` uses nanoseconds since boot
Example migration:
```json
// v0 (old)
{"timestamp": 1234567890, "type": "file", "path": "/etc/config"}
// v1 (new)
{"ts_ns": 1234567890000000000, "src": "tracepoint:syscalls:sys_enter_openat", "pid": 1234, "cgroup_id": 5678, "event": {"type": "file_access", "path": "/etc/config", "flags": 0, "mode": 0, "access": "read"}}
```

### Health Checks
```bash
# Quick health check
stella signals health
# Detailed status
stella signals status --verbose
# Prometheus metrics
curl localhost:9090/metrics | grep stellaops_signals
```
### Log Analysis
```bash
# View recent logs
journalctl -u stellaops-signals --since "1 hour ago"
# Filter by severity
journalctl -u stellaops-signals -p err
# Follow live
journalctl -u stellaops-signals -f
```
## Common Issues
### Issue: Probe Failed to Attach
**Symptoms:**
```
Error: Failed to attach tracepoint/syscalls/sys_enter_openat: permission denied
```
**Diagnosis:**
```bash
# Check capabilities
getcap /usr/bin/stella
# Check kernel config
cat /boot/config-$(uname -r) | grep CONFIG_BPF
# Check seccomp/AppArmor
dmesg | grep -i "bpf\|seccomp\|apparmor"
```
**Resolution:**
1. Ensure proper capabilities:
```bash
sudo setcap cap_bpf,cap_perfmon,cap_sys_ptrace+ep /usr/bin/stella
```
2. Or run as root:
```bash
sudo stella signals start
```
3. Check AppArmor/SELinux isn't blocking
---
### Issue: Ring Buffer Overflow
**Symptoms:**
```
Warning: Ring buffer full, 1523 events dropped
```
**Diagnosis:**
```bash
# Check buffer usage
stella signals stats | grep ringbuf
# Check event rate
stella signals stats | grep rate
```
**Resolution:**
1. Increase buffer size:
```yaml
signals:
ring_buffer_size: 1048576 # 1MB
```
2. Enable rate limiting:
```yaml
signals:
max_events_per_second: 50000
```
3. Add more aggressive filtering:
```yaml
signals:
filters:
paths:
denylist:
- /proc/**
- /sys/**
```
---
### Issue: High Memory Usage
**Symptoms:**
- OOM kills
- High RSS in process stats
**Diagnosis:**
```bash
# Check memory breakdown
stella signals stats --memory
# Check cache sizes
stella signals cache-stats
```
**Resolution:**
1. Reduce cache sizes:
```yaml
signals:
resources:
symbol_cache_max_entries: 50000
max_cache_memory_mb: 128
```
2. Reduce container cache TTL:
```yaml
signals:
resources:
container_cache_ttl_seconds: 60
```
---
### Issue: Symbol Resolution Failures
**Symptoms:**
```
Symbol: addr:0x7f4a3b2c1000 (unresolved)
```
**Diagnosis:**
```bash
# Check if binary has symbols
nm /path/to/binary | head
# Check if debuginfo available
file /path/to/binary | grep "not stripped"
```
**Resolution:**
1. Install debug symbols:
```bash
# Debian/Ubuntu
apt install libc6-dbg
# RHEL/CentOS
debuginfo-install glibc
```
2. Accept address-only evidence (still valuable for correlation)
---
### Issue: Container Resolution Failures
**Symptoms:**
```
container_id: unknown:1234567890
```
**Diagnosis:**
```bash
# Check cgroup path format
cat /proc/<pid>/cgroup
# Verify container runtime
docker ps
crictl ps
```
**Resolution:**
1. Verify Zastava integration is running
2. Check container runtime is supported (containerd/Docker/CRI-O)
3. Restart collector to refresh container mappings
---
### Issue: Evidence Chain Verification Failure
**Symptoms:**
```
$ stella signals verify-chain /var/lib/stellaops/evidence/
Chain Status: ✗ INVALID
Error: Chain broken at chunk 42
```
**Diagnosis:**
```bash
# Get detailed report
stella signals verify-chain /var/lib/stellaops/evidence/ --verbose --format json
```
**Resolution:**
1. Check for missing chunk files
2. Check for disk corruption
3. If intentional restart, document gap in audit trail
4. Re-initialize chain if necessary:
```bash
stella signals reset-chain --confirm
```
---
### Issue: Rekor Submission Failures
**Symptoms:**
```
Warning: Failed to submit to Rekor: connection refused
```
**Diagnosis:**
```bash
# Check Rekor connectivity
curl https://rekor.sigstore.dev/api/v1/log
# Check signing service
stella signer status
```
**Resolution:**
1. Check network connectivity to Rekor
2. Verify Fulcio/OIDC tokens are valid
3. Switch to offline mode temporarily:
```yaml
signals:
signing:
submit_to_rekor: false
```
4. Retry failed submissions later:
```bash
stella signals resubmit-pending
```
## Operational Procedures
### Procedure: Rotate Evidence Directory
When evidence directory is full or needs archival:
```bash
# 1. Stop collector gracefully
stella signals stop
# 2. Archive current evidence
tar -czvf evidence-$(date +%Y%m%d).tar.gz /var/lib/stellaops/evidence/
# 3. Verify archive integrity
stella signals verify-chain evidence-$(date +%Y%m%d).tar.gz
# 4. Move to long-term storage
aws s3 cp evidence-$(date +%Y%m%d).tar.gz s3://evidence-archive/
# 5. Clear old evidence (keep chain state)
stella signals cleanup --keep-chain-state --older-than 7d
# 6. Restart collector
stella signals start
```
### Procedure: Update Collector
```bash
# 1. Check current version
stella version
# 2. Download new version
curl -fsSL https://stella.ops/install.sh | bash -s -- --version 1.2.0
# 3. Verify probe compatibility
stella signals test-probes
# 4. Restart service
sudo systemctl restart stellaops-signals
# 5. Verify operation
stella signals status
```
### Procedure: Recover from Crash
```bash
# 1. Check service status
systemctl status stellaops-signals
# 2. Check for core dumps
coredumpctl list | grep stella
# 3. Review logs for cause
journalctl -u stellaops-signals --since "30 min ago"
# 4. Verify chain state
stella signals verify-chain /var/lib/stellaops/evidence/
# 5. Restart service
sudo systemctl start stellaops-signals
# 6. Monitor for recurrence
watch -n 5 'stella signals stats'
```
### Procedure: Air-Gap Evidence Export
```bash
# 1. Create signed export bundle
stella signals export \
--from 2026-01-01 \
--to 2026-01-31 \
--include-proofs \
--output january-evidence.tar.gz
# 2. Generate verification manifest
stella signals manifest january-evidence.tar.gz > manifest.json
# 3. Transfer to verification system
scp january-evidence.tar.gz manifest.json airgap-verifier:
# 4. On verifier, import and verify
stella signals import january-evidence.tar.gz
stella signals verify-chain --offline /imported/evidence/
```

# Probe Reference
## Overview
This document details each eBPF probe used for runtime evidence collection, including kernel requirements, captured data, and known limitations.
## Tracepoint Probes
### sys_enter_openat
**Location:** `tracepoint/syscalls/sys_enter_openat`
**Purpose:** Capture file access operations to prove which files were read or written.
**Kernel Requirement:** 2.6.16+ (openat syscall), 4.14+ for eBPF attachment
**Source File:** `src/Signals/__Libraries/StellaOps.Signals.Ebpf/Probes/Bpf/syscall_openat.bpf.c`
**Captured Fields:**
| Field | Type | Description |
|-------|------|-------------|
| `timestamp_ns` | u64 | Nanoseconds since boot |
| `pid` | u32 | Process ID |
| `tid` | u32 | Thread ID |
| `cgroup_id` | u64 | Kernel cgroup ID |
| `dfd` | int | Directory file descriptor |
| `flags` | int | Open flags (O_RDONLY, O_WRONLY, etc.) |
| `mode` | u16 | File mode for creation |
| `filename` | char[256] | File path |
| `comm` | char[16] | Process command name |
**Filtering:**
- Cgroup-based: Only capture events from specified containers
- Path-based: Allowlist/denylist patterns applied in user space
**Fallback:** For kernels without `openat` (pre-2.6.16), attaches to `sys_enter_open` instead.
**Performance Impact:** ~1-2% CPU at 10,000 opens/second
---
### sched_process_exec
**Location:** `tracepoint/sched/sched_process_exec`
**Purpose:** Capture process execution to prove which binaries were invoked.
**Kernel Requirement:** 3.4+ for tracepoint, 4.14+ for eBPF attachment
**Source File:** `src/Signals/__Libraries/StellaOps.Signals.Ebpf/Probes/Bpf/syscall_exec.bpf.c`
**Captured Fields:**
| Field | Type | Description |
|-------|------|-------------|
| `timestamp_ns` | u64 | Nanoseconds since boot |
| `pid` | u32 | Process ID (after exec) |
| `ppid` | u32 | Parent process ID |
| `cgroup_id` | u64 | Kernel cgroup ID |
| `filename` | char[256] | Executed binary path |
| `comm` | char[16] | Process command name |
| `argv0` | char[128] | First argument |
**Argv Capture:**
- Limited to first 4 arguments for safety
- Each argument truncated to 128 bytes
- Uses `bpf_probe_read_user_str()` with bounds checking
**Interpreter Detection:**
- Recognizes shebangs for Python, Node, Ruby, Shell scripts
- Maps `/usr/bin/python script.py` to script path
**Performance Impact:** Minimal (exec rate typically low)
---
### inet_sock_set_state
**Location:** `tracepoint/sock/inet_sock_set_state`
**Purpose:** Capture TCP connection lifecycle to prove network communication patterns.
**Kernel Requirement:** 4.16+ (tracepoint added), BTF recommended for CO-RE
**Source File:** `src/Signals/__Libraries/StellaOps.Signals.Ebpf/Probes/Bpf/syscall_network.bpf.c`
**Captured Fields:**
| Field | Type | Description |
|-------|------|-------------|
| `timestamp_ns` | u64 | Nanoseconds since boot |
| `pid` | u32 | Process ID |
| `cgroup_id` | u64 | Kernel cgroup ID |
| `oldstate` | u8 | Previous TCP state |
| `newstate` | u8 | New TCP state |
| `sport` | u16 | Source port |
| `dport` | u16 | Destination port |
| `family` | u8 | AF_INET (2) or AF_INET6 (10) |
| `saddr_v4` / `saddr_v6` | u32 / u8[16] | Source address |
| `daddr_v4` / `daddr_v6` | u32 / u8[16] | Destination address |
| `comm` | char[16] | Process command name |
**State Transition Filtering:**
- Default: Only `* -> ESTABLISHED` and `* -> CLOSE`
- Configurable: All transitions for debugging
**Address Formatting:**
- IPv4: Dotted decimal (e.g., `192.168.1.1`)
- IPv6: RFC 5952 compressed (e.g., `2001:db8::1`)
**Performance Impact:** ~1% CPU at high connection rate
---
## Uprobe Probes
### libc connect/accept
**Location:**
- `uprobe/libc.so.6:connect`
- `uretprobe/libc.so.6:connect`
- `uprobe/libc.so.6:accept`
- `uprobe/libc.so.6:accept4`
**Purpose:** Capture network operations at libc level as alternative to kernel tracepoints.
**Library Support:**
- glibc: `libc.so.6`
- musl: `libc.musl-*.so.1`
**Source File:** `src/Signals/__Libraries/StellaOps.Signals.Ebpf/Probes/Bpf/uprobe_libc.bpf.c`
**Captured Fields (connect):**
| Field | Type | Description |
|-------|------|-------------|

| `addr` | varies | Remote address |
| `port` | u16 | Remote port |
| `comm` | char[16] | Process command name |
| `result` | int | Return value (from uretprobe) |
**Library Path Resolution:**
1. Parse `/etc/ld.so.cache` for library locations
2. Fall back to common paths (`/lib/x86_64-linux-gnu/`, etc.)
3. Handle container-specific paths via `/proc/{pid}/root`
**Byte Counting (optional):**
- `uprobe/libc.so.6:read` and `uprobe/libc.so.6:write`
- Tracks bytes per file descriptor
- Aggregated to prevent event flood
---
### OpenSSL SSL_read/SSL_write
**Location:**
- `uprobe/libssl.so.3:SSL_read`
- `uretprobe/libssl.so.3:SSL_read`
- `uprobe/libssl.so.3:SSL_write`
- `uretprobe/libssl.so.3:SSL_write`
**Purpose:** Capture TLS traffic volumes without decryption.
**Library Support:**
- OpenSSL 1.1.x: `libssl.so.1.1`
- OpenSSL 3.x: `libssl.so.3`
- LibreSSL: `libssl.so.*` (best-effort)
- BoringSSL: Limited support
**Source File:** `src/Signals/__Libraries/StellaOps.Signals.Ebpf/Probes/Bpf/uprobe_openssl.bpf.c`

| `actual_bytes` | u32 | Bytes transferred (from uretprobe) |
| `ssl_ptr` | u64 | SSL context pointer |
| `comm` | char[16] | Process command name |
**Session Correlation:**
- `ssl_ptr` can correlate with `SSL_get_fd` for socket mapping
- Optional: `SSL_get_peer_certificate` for peer info
**Byte Aggregation:**
- High-throughput connections aggregate to periodic summaries
- Prevents event flood on bulk data transfer
---
### Function Tracer (Generic)
**Location:** `uprobe/{binary}:{symbol}`
**Purpose:** Attach to arbitrary function symbols for custom evidence.
**Source File:** `src/Signals/__Libraries/StellaOps.Signals.Ebpf/Probes/Bpf/function_tracer.bpf.c`
**Captured Fields:**
| Field | Type | Description |
|-------|------|-------------|
| `timestamp_ns` | u64 | Nanoseconds since boot |
| `pid` | u32 | Process ID |
| `cgroup_id` | u64 | Kernel cgroup ID |
| `address` | u64 | Runtime address |
| `symbol_id` | u32 | Symbol identifier (from BPF map) |
| `comm` | char[16] | Process command name |
**Symbol Resolution:**
- User-space resolves address to symbol via ELF tables
- ASLR offset calculated from `/proc/{pid}/maps`
- Cached for performance
---
## Kernel Version Compatibility
| Feature | Minimum Kernel | Recommended |
|---------|---------------|-------------|
| Basic eBPF | 4.14 | 5.x+ |
| BTF (CO-RE) | 5.2 | 5.8+ |
| Ring buffer | 5.8 | 5.8+ |
| `sys_enter_openat` | 4.14 | 5.x+ |
| `sched_process_exec` | 4.14 | 5.x+ |
| `inet_sock_set_state` | 4.16 | 5.x+ |
| Uprobes | 4.14 | 5.x+ |
## Known Limitations
### Tracepoints
- **sys_enter_openat**: Path may be relative; resolution requires dfd lookup
- **sched_process_exec**: Argv reading limited by verifier complexity
- **inet_sock_set_state**: UDP not covered; use kprobe for UDP if needed
### Uprobes
- **Library resolution**: May fail for statically linked binaries
- **musl libc**: Some symbol names differ from glibc
- **OpenSSL**: Version detection required for correct symbol names
- **Stripped binaries**: Uprobes require symbol tables
### General
- **eBPF verifier**: Complex programs may be rejected
- **Container namespaces**: Paths may differ from host view
- **High event rate**: Ring buffer overflow possible under extreme load
## Troubleshooting
### Probe Failed to Attach
```
Error: Failed to attach tracepoint/syscalls/sys_enter_openat
```
- Check kernel version supports the tracepoint
- Verify eBPF is enabled (`CONFIG_BPF=y`, `CONFIG_BPF_SYSCALL=y`)
- Check permissions (CAP_BPF or root required)
### Missing BTF
```
Error: BTF not found for kernel version
```
- Install kernel BTF package (`linux-image-*-dbg` on Debian/Ubuntu)
- Use BTFHub for external BTF files
- Fall back to pre-compiled probes for specific kernel
### Ring Buffer Overflow
```
Warning: Ring buffer full, events dropped
```
- Increase buffer size: `--ring-buffer-size 1M`
- Enable more aggressive filtering
- Enable rate limiting: `--max-events-per-second 10000`

```
## Threat Model
### Threat 1: Malicious Workload Evasion
**Description:** Attacker attempts to hide malicious activity from evidence collection.
**Attack Vectors:**
- Disable/bypass eBPF probes
- Use syscalls not monitored
- Operate from unmonitored namespaces
**Mitigations:**
- Collector runs with elevated privileges, not accessible to workloads
- Comprehensive probe coverage (syscalls + uprobes)
- Namespace filtering ensures coverage of target workloads
- Kernel-level capture cannot be bypassed from user space
**Residual Risk:** Novel syscalls or kernel exploits may evade monitoring.
---
### Threat 2: Evidence Tampering
**Description:** Attacker attempts to modify evidence after collection.
**Attack Vectors:**
- Modify NDJSON files on disk
- Delete evidence chunks
- Break chain linkage
**Mitigations:**
- DSSE signatures on each chunk (Fulcio ephemeral keys or KMS)
- Rekor transparency log provides tamper-evident timestamps
- Chain linkage (previous_chunk_id) detects deletions/insertions
- Verification CLI detects any modifications
**Residual Risk:** Attacker with Signer key access could forge valid signatures (mitigated by Fulcio/OIDC).
---
### Threat 3: Collector Compromise
**Description:** Attacker gains control of the collector process.
**Attack Vectors:**
- Exploit vulnerability in collector code
- Compromise host and access collector credentials
- Supply chain attack on collector binary
**Mitigations:**
- Minimal attack surface (single-purpose daemon)
- Capability-based privileges (not full root)
- Signed releases with provenance attestations
- Collector cannot modify already-signed chunks
**Residual Risk:** Zero-day in collector could allow evidence manipulation before signing.
---
### Threat 4: Denial of Service
**Description:** Attacker overwhelms evidence collection system.
**Attack Vectors:**
- Generate excessive events to overflow ring buffer
- Exhaust disk space with evidence
- CPU exhaustion through complex enrichment
**Mitigations:**
- Ring buffer backpressure (events dropped, not crash)
- Rate limiting configurable
- Disk space monitoring with rotation
- Bounded caches prevent memory exhaustion
**Residual Risk:** Sustained attack could cause evidence gaps (documented in chain).
---
### Threat 5: Privacy/Data Exfiltration
**Description:** Evidence contains sensitive information exposed to unauthorized parties.
**Attack Vectors:**
- File paths reveal sensitive locations
- Command arguments contain secrets
- Network destinations reveal infrastructure
**Mitigations:**
- Path filtering (denylist sensitive paths)
- Argument truncation and filtering
- Network CIDR filtering
- Evidence access controlled by filesystem permissions
- Encryption at rest (optional)
**Residual Risk:** Metadata leakage possible even with filtering.
---
### Threat 6: Replay/Injection Attacks
**Description:** Attacker injects fabricated evidence or replays old evidence.
**Attack Vectors:**
- Inject false events into evidence stream
- Replay signed chunks from different time period
- Forge DSSE envelopes
**Mitigations:**
- Ring buffer is kernel-only write
- Timestamps from kernel (monotonic, not settable by user space)
- Chain linkage prevents replay (previous_chunk_id)
- Rekor timestamps provide external time anchor
- DSSE signatures with certificate transparency
**Residual Risk:** Attacker with collector access could inject events before signing.

## Incident Response
### Evidence Integrity Alert
If chain verification fails:
1. **Isolate** affected evidence chunks
2. **Preserve** surrounding chunks and Rekor proofs
3. **Analyze** verification report for failure cause
4. **Report** gap in audit trail to compliance
5. **Investigate** root cause (crash, attack, bug)
### Collector Compromise
If collector compromise suspected:
1. **Stop** collector immediately
2. **Preserve** last signed chunk for forensics
3. **Rotate** signing keys if KMS-based
4. **Audit** Rekor for unexpected submissions
5. **Reinstall** collector from verified source
6. **Resume** collection with new chain

# Release Evidence Pack
This document describes the **Release Evidence Pack** - a self-contained bundle that allows customers to independently verify the authenticity and integrity of Stella Ops releases, even in air-gapped environments.
## Overview
Every Stella Ops release includes a Release Evidence Pack that contains:
1. **Release artifacts** - Binaries, container images, and archives
2. **Checksums** - SHA-256 and SHA-512 hashes for all artifacts
3. **Signatures** - Cosign signatures for cryptographic verification
4. **SBOMs** - Software Bill of Materials in CycloneDX format
5. **Provenance** - SLSA v1.0 provenance statements
6. **Rekor proofs** - Transparency log inclusion proofs (optional)
7. **Verification tools** - Scripts to verify everything offline

```
## Quick Start
### Download the Evidence Pack
Evidence packs are attached to every GitHub release:
```bash
# Download the evidence pack
curl -LO https://github.com/stella-ops/stella-ops/releases/download/v1.2.3/stella-release-1.2.3-evidence-pack.tgz
# Extract
tar -xzf stella-release-1.2.3-evidence-pack.tgz
cd stella-release-1.2.3-evidence-pack
```
### Verify (Quick Method)
```bash
# Run the verification script
./verify.sh
```
On Windows (PowerShell 7+):
```powershell
./verify.ps1
```
### Verify (Manual Method)
If you prefer to verify manually without running scripts:
```bash
# 1. Verify checksums
cd artifacts/
sha256sum -c ../checksums/SHA256SUMS
# 2. Verify checksums signature (requires cosign)
cosign verify-blob \
--key ../cosign.pub \
--signature ../checksums/SHA256SUMS.sig \
../checksums/SHA256SUMS
# 3. Verify artifact signatures
cosign verify-blob \
--key ../cosign.pub \
--signature stella-1.2.3-linux-x64.tar.gz.sig \
stella-1.2.3-linux-x64.tar.gz
```
## Verification Levels
The evidence pack supports multiple verification levels depending on your security requirements:
### Level 1: Checksum Verification (No External Tools)
Verify artifact integrity using standard Unix tools:
```bash
cd artifacts/
sha256sum -c ../checksums/SHA256SUMS
```
**What this proves:** The artifacts have not been modified since the checksums were generated.
### Level 2: Signature Verification (Requires cosign)
Verify that artifacts were signed by Stella Ops:
```bash
cosign verify-blob \
--key cosign.pub \
--signature artifacts/stella-1.2.3-linux-x64.tar.gz.sig \
artifacts/stella-1.2.3-linux-x64.tar.gz
```
**What this proves:** The artifacts were signed by the holder of the Stella Ops signing key.
### Level 3: Provenance Verification (SLSA)
Verify the build provenance matches expected parameters:
```bash
# Verify provenance signature
cosign verify-blob \
--key cosign.pub \
--signature provenance/stella-cli.slsa.intoto.jsonl.sig \
provenance/stella-cli.slsa.intoto.jsonl
# Inspect provenance
cat provenance/stella-cli.slsa.intoto.jsonl | jq .predicate
```
**What this proves:** The artifacts were built from a specific source commit using a specific builder.
### Level 4: Transparency Log Verification (Requires Network)
Verify the signatures were recorded in the Rekor transparency log:
```bash
rekor-cli verify \
--artifact artifacts/stella-1.2.3-linux-x64.tar.gz \
--signature artifacts/stella-1.2.3-linux-x64.tar.gz.sig \
--public-key cosign.pub
```
**What this proves:** The signature was publicly recorded at a specific time and cannot be repudiated.
## Offline Verification
The evidence pack is designed for air-gapped environments. All verification can be done offline except for Rekor transparency log verification.
For fully offline verification including Rekor proofs, the bundle includes pre-fetched inclusion proofs in `rekor-proofs/`.
## SLSA Compliance
Stella Ops releases target **SLSA Level 2** compliance:
| SLSA Requirement | Implementation |
|-----------------|----------------|
| Source - Version controlled | Git repository with signed commits |
| Build - Scripted build | Automated CI/CD pipeline |
| Build - Build service | GitHub Actions / Gitea Actions |
| Provenance - Available | SLSA v1.0 provenance statements |
| Provenance - Authenticated | Cosign signatures on provenance |
The SLSA provenance includes:
- **Builder ID**: The CI system that built the artifact
- **Source commit**: Git SHA of the source code
- **Build type**: The build recipe used
- **Resolved dependencies**: All build inputs with digests
- **Timestamps**: Build start and finish times
## Manifest Schema
The `manifest.json` file contains structured metadata:
```json
{
"bundleFormatVersion": "1.0.0",
"releaseVersion": "1.2.3",
"createdAt": "2025-01-15T10:30:00Z",
"sourceCommit": "abc123...",
"sourceDateEpoch": 1705315800,
"artifacts": [...],
"checksums": {...},
"sboms": [...],
"provenanceStatements": [...],
"attestations": [...],
"rekorProofs": [...],
"signingKeyFingerprint": "...",
"rekorLogId": "..."
}
```
## Build Reproducibility
Stella Ops releases are reproducible. Given the same source code and `SOURCE_DATE_EPOCH`, anyone can produce byte-identical artifacts.
To reproduce a build:
```bash
git clone https://git.stella-ops.org/stella-ops.org/git.stella-ops.org.git
cd git.stella-ops.org
git checkout <source-commit>
export SOURCE_DATE_EPOCH=<from-manifest>
make release
# Compare checksums
sha256sum dist/* | diff - path/to/evidence-pack/checksums/SHA256SUMS
```
## Troubleshooting
### "cosign: command not found"
Install cosign from https://docs.sigstore.dev/cosign/installation/
### Checksum mismatch
1. Re-download the artifact
2. Verify the download completed (check file size)
3. Try a different mirror if available
### Signature verification failed
Ensure you're using the `cosign.pub` from the evidence pack, not a different key.
### Certificate identity mismatch
For keyless-signed artifacts:
```bash
cosign verify-blob \
--certificate-identity "https://ci.stella-ops.org" \
--certificate-oidc-issuer "https://oauth2.sigstore.dev/auth" \
--signature artifact.sig \
artifact
```
## Security Considerations
1. **Verify the evidence pack itself** - Download from official sources only
2. **Check the signing key** - Compare `cosign.pub` fingerprint against published key
3. **Verify provenance** - Ensure builder ID matches expected CI system
4. **Use transparency logs** - When possible, verify Rekor inclusion

## Release Evidence Pack
Every release includes a **Release Evidence Pack** for customer verification and compliance.
### Evidence Pack Contents
| Component | Description |
|-----------|-------------|
| Artifacts | Release binaries and container references |
| Checksums | SHA-256 and SHA-512 checksum files |
| Signatures | Cosign signatures for all artifacts |
| SBOMs | CycloneDX Software Bill of Materials |
| Provenance | SLSA v1.0 provenance statements |
| Rekor Proofs | Transparency log inclusion proofs |
| Verification Scripts | `verify.sh` and `verify.ps1` |
### Generation Workflow
The evidence pack is generated by `.gitea/workflows/release-evidence-pack.yml`:
1. **Verify Test Gates** - Ensures all test workflows passed
2. **Generate Checksums** - Create SHA256SUMS and SHA512SUMS
3. **Sign Artifacts** - Sign with cosign (keyless or key-based)
4. **Generate SBOMs** - Create CycloneDX SBOMs per artifact
5. **Generate Provenance** - Create SLSA v1.0 statements
6. **Collect Rekor Proofs** - Fetch inclusion proofs from Rekor
7. **Build Pack** - Assemble final evidence pack bundle
8. **Self-Verify** - Run verify.sh to validate the pack
### Manual Trigger
```bash
# Trigger evidence pack generation for a release
gh workflow run release-evidence-pack.yml \
-f version=2.5.0 \
-f release_tag=v2.5.0
```
### Verification
Customers can verify releases offline:
```bash
tar -xzf stella-release-2.5.0-evidence-pack.tgz
cd stella-release-2.5.0-evidence-pack
./verify.sh --verbose
```
See [Release Evidence Pack](./RELEASE_EVIDENCE_PACK.md) for detailed documentation.
---
## Reproducible Builds
All release builds are reproducible using `SOURCE_DATE_EPOCH`:
```bash
# Set from git commit timestamp
export SOURCE_DATE_EPOCH=$(git show -s --format=%ct HEAD)
# Build with deterministic settings
dotnet build -c Release /p:Deterministic=true /p:ContinuousIntegrationBuild=true
```
The CI verifies reproducibility by building twice and comparing checksums.
See [Reproducible Builds](./REPRODUCIBLE_BUILDS.md) for details.
---
## Post-Release Tasks
- [ ] Verify artifacts in registry
- [ ] Generate and publish Release Evidence Pack
- [ ] Verify evidence pack passes self-verification
- [ ] Update documentation site
- [ ] Send release announcement
- [ ] Update compatibility matrix

# Reproducible Builds
Stella Ops releases are **reproducible**: given the same source code and build environment, anyone can produce byte-identical artifacts.
## Overview
Reproducible builds provide:
1. **Verifiability** - Anyone can verify that released binaries match source code
2. **Trust** - No need to trust the build infrastructure
3. **Auditability** - Build process can be independently audited
4. **Security** - Compromised builds can be detected
## How It Works
### SOURCE_DATE_EPOCH
All timestamps in build outputs use the `SOURCE_DATE_EPOCH` environment variable instead of the current time. This is set to the git commit timestamp:
```bash
export SOURCE_DATE_EPOCH=$(git show -s --format=%ct HEAD)
```
### Deterministic Build Settings
The following MSBuild properties ensure deterministic .NET builds:
```xml
<!-- src/Directory.Build.props -->
<PropertyGroup>
<Deterministic>true</Deterministic>
<ContinuousIntegrationBuild>true</ContinuousIntegrationBuild>
<PathMap>$(MSBuildProjectDirectory)=/src/</PathMap>
<EmbedUntrackedSources>true</EmbedUntrackedSources>
</PropertyGroup>
```
### Pinned Dependencies
All dependencies are pinned to exact versions in `Directory.Packages.props`:
```xml
<PackageVersion Include="Newtonsoft.Json" Version="13.0.3" />
```
### Containerized Builds
Release builds run in containerized environments with:
- Fixed base images
- Pinned tool versions
- Isolated network (no external fetches during build)
## Reproducing a Build
### Prerequisites
- .NET SDK (version in `global.json`)
- Git
- Docker (optional, for containerized builds)
### Steps
1. **Clone the repository**
```bash
git clone https://git.stella-ops.org/stella-ops.org/git.stella-ops.org.git
cd git.stella-ops.org
```
2. **Checkout the release tag**
```bash
git checkout v1.2.3
```
3. **Set SOURCE_DATE_EPOCH**
Get the value from the release evidence pack `manifest.json`:
```bash
export SOURCE_DATE_EPOCH=1705315800
```
Or compute from git:
```bash
export SOURCE_DATE_EPOCH=$(git show -s --format=%ct HEAD)
```
4. **Build**
```bash
# Using make
make release
# Or using dotnet directly
dotnet publish src/Cli/StellaOps.Cli/StellaOps.Cli.csproj \
--configuration Release \
--runtime linux-x64 \
--self-contained true \
/p:Deterministic=true \
/p:ContinuousIntegrationBuild=true \
/p:SourceRevisionId=$(git rev-parse HEAD)
```
5. **Compare checksums**
```bash
sha256sum dist/stella-* | diff - path/to/evidence-pack/checksums/SHA256SUMS
```
## CI Verification
The CI pipeline automatically verifies reproducibility:
1. Builds artifacts twice with the same `SOURCE_DATE_EPOCH`
2. Compares checksums between builds
3. Fails if checksums don't match
See `.gitea/workflows/verify-reproducibility.yml`.
## What Can Cause Non-Reproducibility
### Timestamps
- **Problem**: Build tools embed current time
- **Solution**: Use `SOURCE_DATE_EPOCH`
### Path Information
- **Problem**: Absolute paths embedded in binaries/PDBs
- **Solution**: Use `PathMap` to normalize paths
### Random Values
- **Problem**: GUIDs, random seeds
- **Solution**: Use deterministic generation or inject via DI
### Unordered Collections
- **Problem**: Dictionary/HashSet iteration order varies
- **Solution**: Use `ImmutableSortedDictionary` or explicit sorting
### External Resources
- **Problem**: Network fetches return different content
- **Solution**: Pin dependencies, use hermetic builds
### Compiler/Tool Versions
- **Problem**: Different tool versions produce different output
- **Solution**: Pin all tool versions in `global.json` and CI
## Debugging Non-Reproducible Builds
### Compare binaries
```bash
# Install diffoscope
pip install diffoscope
# Compare two builds
diffoscope build1/stella.dll build2/stella.dll
```
### Check for timestamps
```bash
# Look for embedded timestamps
strings stella.dll | grep -E '20[0-9]{2}-[0-9]{2}'
```
### Check PDB content
```bash
# Examine PDB for path information
dotnet tool install -g dotnet-symbol
dotnet symbol --symbols stella.dll
```
## Verification in Evidence Pack
The Release Evidence Pack includes:
1. **SOURCE_DATE_EPOCH** in `manifest.json`
2. **Source commit** for exact source checkout
3. **Checksums** for comparison
4. **Build instructions** in `VERIFY.md`

# SLSA Compliance
This document describes Stella Ops' compliance with the [Supply-chain Levels for Software Artifacts (SLSA)](https://slsa.dev/) framework.
## Current SLSA Level
Stella Ops releases target **SLSA Level 2** with ongoing work toward Level 3.
| Level | Status | Description |
|-------|--------|-------------|
| SLSA 1 | ✅ Complete | Provenance exists and shows build process |
| SLSA 2 | ✅ Complete | Provenance is signed and generated by hosted build service |
| SLSA 3 | 🔄 In Progress | Build platform provides strong isolation guarantees |
## SLSA v1.0 Provenance
### Predicate Type
Stella Ops uses the standard SLSA v1.0 provenance predicate:
```
https://slsa.dev/provenance/v1
```
### Provenance Structure
```json
{
"_type": "https://in-toto.io/Statement/v1",
"subject": [
{
"name": "stella-1.2.3-linux-x64.tar.gz",
"digest": {
"sha256": "abc123..."
}
}
],
"predicateType": "https://slsa.dev/provenance/v1",
"predicate": {
"buildDefinition": {
"buildType": "https://stella-ops.io/ReleaseBuilder/v1",
"externalParameters": {
"version": "1.2.3",
"target": "linux-x64"
},
"resolvedDependencies": [
{
"uri": "git+https://git.stella-ops.org/stella-ops.org/git.stella-ops.org@v1.2.3",
"digest": {
"gitCommit": "abc123..."
}
}
]
},
"runDetails": {
"builder": {
"id": "https://ci.stella-ops.org/builder/v1"
},
"metadata": {
"invocationId": "12345/1",
"startedOn": "2025-01-15T10:30:00Z",
"finishedOn": "2025-01-15T10:45:00Z"
}
}
}
}
```
## Verification
### Verifying Provenance Signature
```bash
cosign verify-blob \
--key cosign.pub \
--signature provenance/stella-cli.slsa.intoto.jsonl.sig \
provenance/stella-cli.slsa.intoto.jsonl
```
### Inspecting Provenance
```bash
# View full provenance
cat provenance/stella-cli.slsa.intoto.jsonl | jq .
# Extract builder ID
cat provenance/stella-cli.slsa.intoto.jsonl | jq -r '.predicate.runDetails.builder.id'
# Extract source commit
cat provenance/stella-cli.slsa.intoto.jsonl | jq -r '.predicate.buildDefinition.resolvedDependencies[0].digest.gitCommit'
```
### Policy Verification
Verify provenance matches your policy:
```bash
# Example: Verify builder ID
BUILDER_ID=$(cat provenance/stella-cli.slsa.intoto.jsonl | jq -r '.predicate.runDetails.builder.id')
if [ "$BUILDER_ID" != "https://ci.stella-ops.org/builder/v1" ]; then
echo "ERROR: Unknown builder"
exit 1
fi
```
## Strict Validation Mode
Stella Ops supports strict SLSA validation that enforces:
1. **Valid builder ID URI** - Must be a valid absolute URI
2. **Approved digest algorithms** - sha256, sha384, sha512, sha3-*
3. **RFC 3339 timestamps** - All timestamps must be properly formatted
4. **Minimum SLSA level** - Configurable minimum level requirement
### Configuration
In `appsettings.json`:
```json
{
"Attestor": {
"Slsa": {
"ValidationMode": "Strict",
"MinimumSlsaLevel": 2,
"AllowedBuilderIds": [
"https://ci.stella-ops.org/builder/v1",
"https://github.com/actions/runner"
]
}
}
}
```

# Offline Verification Guide
This guide explains how to verify Stella Ops releases in air-gapped or offline environments without network access.
## Overview
The Release Evidence Pack is designed for complete offline verification. All cryptographic materials and proofs are bundled together, allowing verification without contacting external services.
## Verification Levels
Stella Ops supports multiple verification levels depending on your security requirements and available tools:
| Level | Tools Required | Network | Security Assurance |
|-------|---------------|---------|-------------------|
| 1 - Checksum | sha256sum | None | Artifact integrity |
| 2 - Signature | sha256sum + cosign | None | Authenticity + integrity |
| 3 - Provenance | sha256sum + cosign + jq | None | Build chain verification |
| 4 - Transparency | sha256sum + cosign + rekor-cli | Optional | Non-repudiation |
## Prerequisites
### Minimal (Level 1)
Standard Unix tools available on most systems:
- `sha256sum` or `shasum`
- `cat`, `diff`
### Full Verification (Levels 2-4)
Install cosign for signature verification:
```bash
# Linux
curl -sSL https://github.com/sigstore/cosign/releases/latest/download/cosign-linux-amd64 -o cosign
chmod +x cosign
sudo mv cosign /usr/local/bin/
# macOS
brew install cosign
# Windows (PowerShell)
scoop install cosign
# or download from GitHub releases
```
## Quick Start
### Using the Verification Script
The evidence pack includes a self-contained verification script:
```bash
# Extract the evidence pack
tar -xzf stella-release-2.5.0-evidence-pack.tgz
cd stella-release-2.5.0-evidence-pack
# Run verification
./verify.sh
# For verbose output
./verify.sh --verbose
# For JSON output (CI integration)
./verify.sh --json
```
On Windows (PowerShell 7+):
```powershell
# Extract
Expand-Archive stella-release-2.5.0-evidence-pack.zip -DestinationPath .
cd stella-release-2.5.0-evidence-pack
# Run verification
./verify.ps1
```
### Exit Codes
The verification scripts return specific exit codes:
| Code | Meaning |
|------|---------|
| 0 | All verifications passed |
| 1 | Checksum verification failed |
| 2 | Signature verification failed |
| 3 | Provenance verification failed |
| 4 | Configuration error |
## Manual Verification Steps
### Level 1: Checksum Verification
Verify artifact integrity using SHA-256 checksums:
```bash
cd artifacts/
sha256sum -c ../checksums/SHA256SUMS
```
Expected output:
```
stella-2.5.0-linux-x64.tar.gz: OK
stella-2.5.0-linux-arm64.tar.gz: OK
stella-2.5.0-macos-universal.tar.gz: OK
stella-2.5.0-windows-x64.zip: OK
```
### Level 2: Signature Verification
Verify that artifacts were signed by Stella Ops:
```bash
# Verify the checksums file signature
cosign verify-blob \
--key cosign.pub \
--signature checksums/SHA256SUMS.sig \
checksums/SHA256SUMS
# Verify individual artifact signatures
cosign verify-blob \
--key cosign.pub \
--signature artifacts/stella-2.5.0-linux-x64.tar.gz.sig \
artifacts/stella-2.5.0-linux-x64.tar.gz
```
### Level 3: Provenance Verification
Verify SLSA provenance and inspect build details:
```bash
# Verify provenance signature
cosign verify-blob \
--key cosign.pub \
--signature provenance/stella-cli.slsa.intoto.jsonl.sig \
provenance/stella-cli.slsa.intoto.jsonl
# Inspect provenance contents
cat provenance/stella-cli.slsa.intoto.jsonl | jq '.'
# Verify builder ID
BUILDER_ID=$(cat provenance/stella-cli.slsa.intoto.jsonl | \
jq -r '.predicate.runDetails.builder.id')
echo "Builder: $BUILDER_ID"
# Verify it matches expected value
if [ "$BUILDER_ID" != "https://ci.stella-ops.org/builder/v1" ]; then
echo "WARNING: Unexpected builder ID"
fi
# Check source commit
SOURCE_COMMIT=$(cat provenance/stella-cli.slsa.intoto.jsonl | \
jq -r '.predicate.buildDefinition.resolvedDependencies[0].digest.gitCommit')
echo "Source commit: $SOURCE_COMMIT"
```
### Level 4: Transparency Log Verification
Verify Rekor inclusion proofs (requires network OR pre-fetched proofs):
#### With Network Access
```bash
rekor-cli verify \
--artifact artifacts/stella-2.5.0-linux-x64.tar.gz \
--signature artifacts/stella-2.5.0-linux-x64.tar.gz.sig \
--public-key cosign.pub
```
#### Offline (using bundled proofs)
The evidence pack includes pre-fetched Rekor proofs in `rekor-proofs/`:
```bash
# List included proofs
cat rekor-proofs/inclusion-proofs.json | jq '.proofs'
# View a specific entry
cat rekor-proofs/log-entries/<uuid>.json | jq '.'
```
## SBOM Verification
Verify Software Bill of Materials:
```bash
# Verify SBOM signature
cosign verify-blob \
--key cosign.pub \
--signature sbom/stella-cli.cdx.json.sig \
sbom/stella-cli.cdx.json
# Inspect SBOM contents
cat sbom/stella-cli.cdx.json | jq '.components | length'
```
## Reproducible Build Verification
Stella Ops releases are reproducible. You can rebuild from source and compare:
```bash
# Get the SOURCE_DATE_EPOCH from manifest
SOURCE_DATE_EPOCH=$(cat manifest.json | jq -r '.sourceDateEpoch')
SOURCE_COMMIT=$(cat manifest.json | jq -r '.sourceCommit')
# Clone and checkout
git clone https://git.stella-ops.org/stella-ops.org/git.stella-ops.org.git
cd git.stella-ops.org
git checkout $SOURCE_COMMIT
# Set reproducible timestamp
export SOURCE_DATE_EPOCH
# Build
make release
# Compare checksums
sha256sum dist/stella-* | diff - path/to/evidence-pack/checksums/SHA256SUMS
```
## Verification in CI/CD
For automated verification in pipelines:
```bash
# Download and verify in one step
curl -sSL https://releases.stella-ops.org/v2.5.0/evidence-pack.tgz | tar -xz
cd stella-release-2.5.0-evidence-pack
# Run verification with JSON output
./verify.sh --json > verification-result.json
# Check result
if [ "$(jq -r '.overall' verification-result.json)" != "PASS" ]; then
echo "Verification failed!"
jq '.steps[] | select(.status == "FAIL")' verification-result.json
exit 1
fi
```
## Troubleshooting
### "cosign: command not found"
Install cosign from https://docs.sigstore.dev/cosign/installation/
### Checksum Mismatch
1. Re-download the artifact
2. Verify download completed (check file size)
3. Try a different mirror if available
4. Check for file corruption during transfer
### Signature Verification Failed
1. Ensure you're using `cosign.pub` from the evidence pack
2. Check the signature file hasn't been corrupted
3. Verify the artifact hasn't been modified
### "Error: no matching entries in transparency log"
This can happen if:
- The artifact was signed with key-based signing (not keyless)
- The Rekor server is unreachable
- Use the bundled proofs in `rekor-proofs/` instead
## Security Considerations
1. **Verify the evidence pack itself** - Download only from official sources
2. **Compare public key fingerprint** - Verify `cosign.pub` fingerprint matches published key
3. **Check provenance builder ID** - Ensure it matches expected CI system
4. **Review SBOM for known vulnerabilities** - Scan dependencies before deployment

# Registry Compatibility Quick Reference
> Sprint: SPRINT_0127_001_0002_oci_registry_compatibility
> Module: Doctor
Quick reference for OCI registry compatibility with StellaOps. For detailed information, see [Registry Diagnostic Checks](../modules/doctor/registry-checks.md).
## Quick Compatibility Check
```bash
# Run all registry diagnostics
stella doctor --tag registry
# Check specific capability
stella doctor --check check.integration.oci.referrers
# Export detailed report
stella doctor --tag registry --format json --output registry-report.json
```
## Supported Registries
| Registry | Referrers API | Recommendation |
|----------|---------------|----------------|
| ACR, ECR, GCR, Harbor 2.6+, Quay 3.12+, JFrog 7.x+, Zot | Native | Full support |
| GHCR, Docker Hub, registry:2 | Fallback | Supported with automatic fallback |
## Common Issues
| Symptom | Check | Likely Cause | Fix |
|---------|-------|--------------|-----|
| "Invalid credentials" | `oci.credentials` | Wrong username/password | Verify credentials, check expiry |
| "No pull permission" | `oci.pull` | Missing reader role | Grant pull/read access |
| "No push permission" | `oci.push` | Missing writer role | Grant push/write access |
| "Referrers API not supported" | `oci.referrers` | Old registry version | Upgrade or use fallback |
| "Artifacts missing in bundle" | `oci.referrers` | Referrers not discovered | Check registry compatibility |
## Registry-Specific Notes
### GHCR (GitHub Container Registry)
- Referrers API not implemented
- StellaOps uses tag-based fallback automatically
- No action required
### Harbor
- Requires version 2.6+ for native referrers API
- Older versions work with fallback
### Docker Hub
- Rate limits may affect probes
- Use authenticated requests for higher limits
## Verification Commands
```bash
# Test registry connectivity
curl -I https://registry.example.com/v2/
# Test referrers API
curl -H "Accept: application/vnd.oci.image.index.v1+json" \
"https://registry.example.com/v2/repo/referrers/sha256:..."
# Test with docker CLI
docker login registry.example.com
docker pull registry.example.com/repo:tag
```

# Registry Referrer Discovery Troubleshooting
> Sprint: SPRINT_0127_001_0001_oci_referrer_bundle_export
> Module: ExportCenter, AirGap
This runbook covers diagnosing and resolving OCI referrer discovery issues during mirror bundle exports.
## Quick Reference
| Symptom | Likely Cause | Solution |
|---------|--------------|----------|
| No referrers discovered | Registry doesn't support referrers API | Check [registry compatibility](#registry-compatibility-quick-reference) |
| Discovery timeout | Network issues or slow registry | Increase timeout, check connectivity |
| Partial referrers | Rate limiting or auth issues | Check credentials and rate limits |
| Checksum mismatch | Referrer modified after discovery | Re-export bundle |
## Registry Compatibility Quick Reference
| Registry | OCI 1.1 API | Fallback | Notes |
|----------|-------------|----------|-------|
| Docker Hub | Partial | Yes | Rate limits may affect discovery |
| GHCR | No | Yes | Uses tag-based discovery only |
| GCR | Yes | Yes | Full OCI 1.1 support |
| ECR | Yes | Yes | Requires proper IAM permissions |
| ACR | Yes | Yes | Full OCI 1.1 support |
| Harbor 2.0+ | Yes | Yes | Full OCI 1.1 support |
| Quay | Partial | Yes | Varies by version |
| JFrog Artifactory | Partial | Yes | Requires OCI layout repository |
See [Registry Compatibility Matrix](../modules/export-center/registry-compatibility.md) for detailed information.
## Diagnosing Issues
### 1. Check Export Logs
Look for capability probing and discovery logs:
```bash
# Look for probing logs
grep "Probing.*registries for OCI referrer" /var/log/stellaops/export-center.log
# Check individual registry results
grep "Registry.*OCI 1" /var/log/stellaops/export-center.log
# Example output:
# [INFO] Probing 2 registries for OCI referrer capabilities before export
# [INFO] Registry gcr.io: OCI 1.1 (referrers API supported, version=OCI-Distribution/2.1, probe_ms=42)
# [WARN] Registry ghcr.io: OCI 1.0 (using fallback tag discovery, version=registry/2.0, probe_ms=85)
```
### 2. Check Telemetry Metrics
Query Prometheus for referrer discovery metrics:
```promql
# Capability probes by registry and support status
sum by (registry, api_supported) (
rate(export_registry_capabilities_probed_total[5m])
)
# Discovery method breakdown
sum by (registry, method) (
rate(export_referrer_discovery_method_total[5m])
)
# Failure rate by registry
sum by (registry) (
rate(export_referrer_discovery_failures_total[5m])
)
```
### 3. Test Registry Connectivity
Manually probe registry capabilities:
```bash
# Test OCI referrers API (OCI 1.1)
curl -H "Accept: application/vnd.oci.image.index.v1+json" \
"https://registry.example.com/v2/myrepo/referrers/sha256:abc123..."
# Expected responses:
# - 200 OK with manifest list: Registry supports referrers API
# - 404 Not Found: No referrers exist (API supported)
# - 501 Not Implemented: Registry doesn't support referrers API
# Check distribution version
curl -I "https://registry.example.com/v2/"
# Look for: OCI-Distribution-API-Version header
```
### 4. Test Fallback Tag Discovery
If native API is not supported:
```bash
# List tags matching fallback pattern
curl "https://registry.example.com/v2/myrepo/tags/list" | \
jq '.tags | map(select(startswith("sha256-")))'
# Expected: Tags like "sha256-abc123.sbom", "sha256-abc123.att"
```
## Common Issues and Solutions
### Issue: "Failed to probe capabilities for registry"
**Symptoms:**
- Warning logs about probe failures
- Referrer discovery using fallback or skipped
**Causes:**
1. Network connectivity issues
2. Authentication failures
3. Registry rate limiting
4. TLS certificate issues
**Solutions:**
```bash
# Check network connectivity
curl -v "https://registry.example.com/v2/"
# Verify authentication
docker login registry.example.com
# Check TLS certificates
openssl s_client -connect registry.example.com:443 -servername registry.example.com
```
### Issue: "No referrers found for image"
**Symptoms:**
- Discovery succeeds but returns empty list
- Bundle missing expected SBOMs/attestations
**Causes:**
1. No referrers actually attached to image
2. Referrers attached to different digest (tag vs digest mismatch)
3. Referrers pruned by registry retention policy
**Solutions:**
```bash
# Verify referrers exist for the specific digest
crane manifest registry.example.com/repo@sha256:abc123 | \
jq '.subject.digest'
# List referrers using oras
oras discover registry.example.com/repo@sha256:abc123
# Check if referrers exist with different artifact types
curl "https://registry.example.com/v2/repo/referrers/sha256:abc123?artifactType=application/vnd.cyclonedx%2Bjson"
```
### Issue: "Referrer checksum mismatch during import"
**Symptoms:**
- `ImportValidator` reports `ReferrerChecksumMismatch`
- Bundle verification fails
**Causes:**
1. Referrer artifact modified after export
2. Registry replaced artifact
3. Bundle corruption during transfer
**Solutions:**
1. Re-export the bundle to get fresh referrer content
2. Verify bundle integrity: `sha256sum bundle.tgz`
3. Check if referrer was intentionally updated upstream
### Issue: Slow referrer discovery
**Symptoms:**
- Export takes much longer than expected
- Timeout warnings in logs
**Causes:**
1. Large number of referrers per image
2. Slow registry responses
3. No capability caching (cache miss)
**Solutions:**
```yaml
# Increase timeout in export config
export:
referrer_discovery:
timeout_seconds: 120
max_concurrent_discoveries: 4
```
## Validation Commands
### Verify Bundle Referrers
```bash
# Extract and list referrer structure
tar -tzf bundle.tgz | grep "^referrers/"
# Check manifest for referrer counts
tar -xzf bundle.tgz -O manifest.yaml | grep -A5 "referrers:"
# Validate a specific referrer checksum
tar -xzf bundle.tgz -O referrers/sha256-abc123/sha256-def456.json | sha256sum
```
### CLI Validation
```bash
# Validate bundle referrers
stellaops bundle validate --file bundle.tgz --check-referrers
# Import with strict referrer validation
stellaops bundle import --file bundle.tgz --strict-referrer-validation
```
## Escalation
If issues persist after following this runbook:
1. Collect diagnostic information:
- Export logs with DEBUG level enabled
- Telemetry metrics for the affected time window
- Registry type and version
- Network trace if applicable
2. Check [known issues](https://github.com/stella-ops/issues?q=label:referrer-discovery)
3. Open a support ticket with:
- Environment details (StellaOps version, registry type)
- Error messages and logs
- Steps to reproduce

# Post-Incident Testing Guide
**Version:** 1.0
**Status:** Turn #6 Implementation
**Audience:** StellaOps developers, QA engineers, incident responders
---
## Overview
Every production incident should produce a permanent regression test. This guide describes the infrastructure and workflow for generating, reviewing, and maintaining post-incident tests in the StellaOps codebase.
### Key Principles
1. **Permanent Regression**: Incidents that reach production indicate a gap in testing. That gap must be permanently closed.
2. **Deterministic Replay**: Tests are generated from replay manifests captured during the incident.
3. **Severity-Gated**: P1/P2 incident tests block releases; P3/P4 tests are warning-only.
4. **Traceable**: Every incident test links back to the incident report and fix.
---
## Workflow
### 1. Incident Triggers Replay Capture
When an incident occurs, the replay infrastructure automatically captures:
- Event sequences with correlation IDs
- Input data (sanitized for PII)
- System state at time of incident
- Configuration and policy digests
This produces a **replay manifest** stored in the Evidence Locker.
### 2. Generate Test Scaffold
Use the `IncidentTestGenerator` to create a test scaffold from the replay manifest:
```csharp
using StellaOps.TestKit.Incident;
// Load the replay manifest
var manifestJson = File.ReadAllText("incident-replay-manifest.json");
// Create incident metadata
var metadata = new IncidentMetadata
{
IncidentId = "INC-2026-001",
OccurredAt = DateTimeOffset.Parse("2026-01-15T10:30:00Z"),
RootCause = "Race condition in concurrent bundle creation",
AffectedModules = ["EvidenceLocker", "Policy"],
Severity = IncidentSeverity.P1,
Title = "Evidence bundle duplication in high-concurrency scenario",
ReportUrl = "https://incidents.stella-ops.internal/INC-2026-001"
};
// Generate the test scaffold
var generator = new IncidentTestGenerator();
var scaffold = generator.GenerateFromManifestJson(manifestJson, metadata);
// Output the generated test code
var code = scaffold.GenerateTestCode();
File.WriteAllText($"Tests/{scaffold.TestClassName}.cs", code);
```
### 3. Review and Complete Test
The generated scaffold is a starting point. A human must:
1. **Review fixtures**: Ensure input data is appropriate and sanitized.
2. **Complete assertions**: Add specific assertions for the expected behavior.
3. **Verify determinism**: Ensure the test produces consistent results.
4. **Add to CI**: Include the test in the appropriate test project.
### 4. Register for Tracking
Register the incident test for reporting:
```csharp
generator.RegisterIncidentTest(metadata.IncidentId, scaffold);
// Generate a summary report
var report = generator.GenerateReport();
Console.WriteLine($"Total incident tests: {report.TotalTests}");
Console.WriteLine($"P1 tests: {report.BySeveority.GetValueOrDefault(IncidentSeverity.P1, 0)}");
```
---
## Incident Metadata
The `IncidentMetadata` record captures essential incident context:
| Property | Required | Description |
|----------|----------|-------------|
| `IncidentId` | Yes | Unique identifier from incident management system |
| `OccurredAt` | Yes | When the incident occurred (UTC) |
| `RootCause` | Yes | Brief description of the root cause |
| `AffectedModules` | Yes | Modules impacted by the incident |
| `Severity` | Yes | P1 (critical) through P4 (low impact) |
| `Title` | No | Short descriptive title |
| `ReportUrl` | No | Link to incident report or postmortem |
| `ResolvedAt` | No | When the incident was resolved |
| `CorrelationIds` | No | IDs for replay matching |
| `FixTaskId` | No | Sprint task that implemented the fix |
| `Tags` | No | Categorization tags |
### Severity Levels
| Severity | Description | CI Behavior |
|----------|-------------|-------------|
| P1 | Critical: service down, data loss, security breach | Blocks releases |
| P2 | Major: significant degradation, partial outage | Blocks releases |
| P3 | Minor: limited impact, workaround available | Warning only |
| P4 | Low: cosmetic issues, minor bugs | Informational |
---
## Generated Test Structure
The scaffold generates a test class with:
```csharp
[Trait("Category", TestCategories.PostIncident)]
[Trait("Incident", "INC-2026-001")]
[Trait("Severity", "P1")]
public sealed class Incident_INC_2026_001_Tests
{
private static readonly IncidentMetadata Incident = new()
{
IncidentId = "INC-2026-001",
OccurredAt = DateTimeOffset.Parse("2026-01-15T10:30:00Z"),
RootCause = "Race condition in concurrent bundle creation",
AffectedModules = ["EvidenceLocker", "Policy"],
Severity = IncidentSeverity.P1,
Title = "Evidence bundle duplication"
};
[Fact]
public async Task Validates_RaceCondition_Fix()
{
// Arrange
// TODO: Load fixtures from replay manifest
// Act
// TODO: Execute the scenario that triggered the incident
// Assert
// TODO: Verify the fix prevents the incident condition
}
}
```
---
## CI Integration
### Test Filtering
Filter post-incident tests in CI:
```bash
# Run all post-incident tests
dotnet test --filter "Category=PostIncident"
# Run only P1/P2 tests (release-gating)
dotnet test --filter "Category=PostIncident&(Severity=P1|Severity=P2)"
# Run tests for a specific incident
dotnet test --filter "Incident=INC-2026-001"
# Run tests for a specific module
dotnet test --filter "Category=PostIncident&Module:EvidenceLocker=true"
```
### CI Lanes
| Lane | Filter | Trigger | Behavior |
|------|--------|---------|----------|
| PR Gate | `Category=PostIncident&(Severity=P1\|Severity=P2)` | Pull requests | Blocks merge |
| Release Gate | `Category=PostIncident` | Release builds | P1/P2 block, P3/P4 warn |
| Nightly | `Category=PostIncident` | Scheduled | Full run, report only |
### Example CI Configuration
```yaml
# .gitea/workflows/post-incident-tests.yml
name: Post-Incident Tests

types: [created]
jobs:

--logger "trx;LogFileName=incident-results.trx"
- name: Upload Results
uses: actions/upload-artifact@v4
with:
name: incident-test-results
path: '**/incident-results.trx'
```
---
## Best Practices
### 1. Sanitize Fixtures
Remove or mask any PII or sensitive data from replay fixtures:
```csharp
// Before storing fixture
var sanitizedFixture = fixture
.Replace(userEmail, "user@example.com")
.Replace(apiKey, "REDACTED");
```
### 2. Use Deterministic Infrastructure
Ensure incident tests use TestKit's deterministic primitives:
```csharp
// Use deterministic time
using var time = new DeterministicTime(Incident.OccurredAt);
// Use deterministic random if needed
var random = new DeterministicRandom(seed: 42);
```
### 3. Document the Incident
Include comprehensive documentation in the test:
```csharp
/// <summary>
/// Regression test for incident INC-2026-001: Evidence bundle duplication.
/// </summary>
/// <remarks>
/// Root cause: Race condition in concurrent bundle creation.
///
/// The incident occurred when multiple workers attempted to create the same
/// evidence bundle simultaneously. The fix added optimistic locking with
/// a unique constraint on (tenant_id, bundle_id).
///
/// Report: https://incidents.stella-ops.internal/INC-2026-001
/// Fix: PR #1234
/// </remarks>
```
### 4. Link to Sprint Tasks
Connect incident tests to the fix implementation:
```csharp
[Fact]
[Trait("SprintTask", "EVIDENCE-0115-001")]
public async Task Validates_RaceCondition_Fix()
```
### 5. Evolve Tests Over Time
Incident tests may need updates as the codebase evolves:
- Update fixtures when schemas change
- Adjust assertions when behavior intentionally changes
- Add new scenarios discovered during subsequent incidents
---
## Troubleshooting
### Manifest Not Available
If the replay manifest wasn't captured:
1. Check Evidence Locker for any captured events
2. Reconstruct the scenario from logs and metrics
3. Create a synthetic manifest for testing
### Flaky Incident Tests
If the test is non-deterministic:
1. Identify non-deterministic inputs (time, random, external state)
2. Replace with TestKit deterministic primitives
3. Add retry logic only as a last resort
### Test No Longer Relevant
If the fix makes the scenario impossible:
1. Document why the test is no longer applicable
2. Move to an "archived incidents" test category

## Turn #6 Enhancements (2026-01-27)
Source advisory: Testing Enhancements (Automation Turn #6)
Sprint: `docs/implplan/SPRINT_0127_002_DOCS_testing_enhancements_turn6.md`
### New test intent categories
Every non-trivial test must declare intent. Intent clarifies *why* the behavior exists.
```csharp
public static class TestIntents
{
public const string Regulatory = "Regulatory"; // Compliance, audit, legal
public const string Safety = "Safety"; // Security, fail-secure, crypto
public const string Performance = "Performance"; // Latency, throughput, resources
public const string Competitive = "Competitive"; // Parity with competitor tools
public const string Operational = "Operational"; // Observability, operability
}
// Usage
[Trait("Intent", TestIntents.Safety)]
[Trait("Category", "Unit")]
public void Signer_RejectsExpiredCertificate() { /* ... */ }
```
### New test trait categories
| Category | Purpose | Example Usage |
|----------|---------|---------------|
| `Intent` | Test intent classification | `[Trait("Intent", "Safety")]` |
| `Evidence` | Evidence chain validation | `[Trait("Category", "Evidence")]` |
| `Observability` | OTel/log/metrics contracts | `[Trait("Category", "Observability")]` |
| `Longevity` | Time-extended stability tests | `[Trait("Category", "Longevity")]` |
| `Interop` | Cross-version/environment skew | `[Trait("Category", "Interop")]` |
| `PostIncident` | Tests from production incidents | `[Trait("Category", "PostIncident")]` |
### Updated test model requirements
| Model | Turn #6 Additions |
|-------|-------------------|
| L0 (Library/Core) | + Intent trait required for non-trivial tests |
| S1 (Storage/Postgres) | + Interop tests for schema version migrations |
| W1 (WebService/API) | + Observability contract tests (OTel spans, log fields, metrics) |
| WK1 (Worker/Indexer) | + Longevity tests for memory/connection stability |
| CLI1 (Tool/CLI) | + PostIncident regression tests |
### New CI lanes
| Lane | Purpose | Cadence | Gating |
|------|---------|---------|--------|
| Evidence | Evidence chain validation, traceability | Per PR | PR-gating for regulatory modules |
| Longevity | Time-extended stability tests | Nightly | Release-gating |
| Interop | Cross-version compatibility | Weekly + pre-release | Release-gating |
### Observability contract requirements (W1 model)
WebService tests must validate:
- **OTel spans**: required spans exist, attributes present, cardinality bounded.
- **Structured logs**: required fields present, no PII, appropriate log levels.
- **Metrics**: required metrics exist, label cardinality bounded, counters monotonic.
```csharp
[Trait("Category", "Observability")]
[Trait("Intent", "Operational")]
public async Task Scanner_EmitsRequiredTelemetry()
{
using var otel = new OtelCapture();
await sut.ScanAsync(request);
OTelContractAssert.HasRequiredSpans(otel, "ScanImage", "ExtractLayers", "AnalyzeSBOM");
OTelContractAssert.NoHighCardinalityAttributes(otel, threshold: 100);
}
```
### Evidence traceability requirements
Regulatory tests must link to requirements:
```csharp
[Requirement("REQ-EVIDENCE-001")]
[Trait("Intent", "Regulatory")]
public void EvidenceBundle_IsImmutableAfterSigning() { /* ... */ }
```
CI generates traceability matrix: requirement -> test -> artifact.
### Cross-version testing requirements (Interop)
For modules with schema or API versioning:
- Test N-1 compatibility (current server, previous client).
- Test N+1 compatibility (previous server, current client).
- Document compatibility matrix.
### Time-extended testing requirements (Longevity)
For worker modules (WK1 model):
- Memory stability: verify no growth under sustained load.
- Connection pool stability: verify no leaks.
- Counter drift: verify values remain bounded.
Run duration: 1+ hours for nightly, 4+ hours for release validation.
### Post-incident testing requirements
For P1/P2 production incidents:
1. Capture event sequence via replay infrastructure.
2. Generate test scaffold from replay manifest.
3. Include incident metadata (ID, root cause, severity).
4. Tag with `[Trait("Category", "PostIncident")]`.
5. Test failures block releases.

### 9. Test Categories
### 9. Observability Contract Testing (Turn #6)
Contract assertions for treating logs, metrics, and traces as APIs:
**OTel Contract Testing:**
```csharp
using StellaOps.TestKit.Observability;
[Fact, Trait("Category", TestCategories.Contract)]
public async Task Test_SpanContracts()
{
using var capture = new OtelCapture("MyService");
await service.ProcessRequestAsync();
// Verify required spans are present
OTelContractAssert.HasRequiredSpans(capture, "ProcessRequest", "ValidateInput", "SaveResult");
// Verify span attributes
var span = capture.CapturedActivities.First();
OTelContractAssert.SpanHasAttributes(span, "user_id", "tenant_id", "correlation_id");
// Check attribute cardinality (prevent metric explosion)
OTelContractAssert.AttributeCardinality(capture, "http_method", maxCardinality: 10);
// Detect high-cardinality attributes globally
OTelContractAssert.NoHighCardinalityAttributes(capture, threshold: 100);
}
```
**Log Contract Testing:**
```csharp
using StellaOps.TestKit.Observability;
using System.Text.RegularExpressions;
[Fact]
public async Task Test_LogContracts()
{
var logCapture = new List<CapturedLogRecord>();
// ... capture logs during test execution ...
// Verify required fields
LogContractAssert.HasRequiredFields(logCapture[0], "CorrelationId", "TenantId");
// Ensure no PII leakage
var piiPatterns = new[]
{
new Regex(@"\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,}\b"), // Email
new Regex(@"\b\d{3}-\d{2}-\d{4}\b"), // SSN
};
LogContractAssert.NoSensitiveData(logCapture, piiPatterns);
// Verify log level appropriateness
LogContractAssert.LogLevelAppropriate(logCapture[0], LogLevel.Information, LogLevel.Warning);

}
```
**Metrics Contract Testing:**
```csharp
using StellaOps.TestKit.Observability;
[Fact]
public async Task Test_MetricsContracts()
{
using var capture = new MetricsCapture("MyService");
await service.ProcessMultipleRequests();
// Verify required metrics exist
MetricsContractAssert.HasRequiredMetrics(capture, "requests_total", "request_duration_seconds");
// Check label cardinality bounds
MetricsContractAssert.LabelCardinalityBounded(capture, "http_requests_total", maxLabels: 50);
// Verify counter monotonicity
MetricsContractAssert.CounterMonotonic(capture, "processed_items_total");
// Verify gauge bounds
MetricsContractAssert.GaugeInBounds(capture, "active_connections", minValue: 0, maxValue: 1000);
}
```
**API Reference:**

---
### 10. Evidence Chain Traceability (Turn #6)
Link tests to requirements for regulatory compliance and audit trails:
**Requirement Attribute:**
```csharp
using StellaOps.TestKit.Evidence;
[Fact]
[Requirement("REQ-AUTH-001", SprintTaskId = "AUTH-0127-001")]
public async Task Test_UserAuthentication()
{
// Verify authentication works as required
}
[Fact]
[Requirement("REQ-AUDIT-002", SprintTaskId = "AUDIT-0127-003", ComplianceControl = "SOC2-AU-12")]
public void Test_AuditLogImmutability()
{
// Verify audit logs cannot be modified
}
```
**Filtering tests by requirement:**
```bash
# Run tests for a specific requirement
dotnet test --filter "Requirement=REQ-AUTH-001"
# Run tests for a sprint task
dotnet test --filter "SprintTask=AUTH-0127-001"
# Run tests for a compliance control
dotnet test --filter "ComplianceControl=SOC2-AU-12"
```
**Evidence Chain Assertions:**
```csharp
using StellaOps.TestKit.Evidence;
[Fact]
[Requirement("REQ-EVIDENCE-001")]
public void Test_ArtifactHashStability()
{
var artifact = GenerateEvidence(input);
// Verify artifact produces expected hash (golden master)
EvidenceChainAssert.ArtifactHashStable(artifact, "abc123...expected-sha256...");
}
[Fact]
[Requirement("REQ-DETERMINISM-001")]
public void Test_EvidenceImmutability()
{
// Verify generator produces identical output across iterations
EvidenceChainAssert.ArtifactImmutable(() => GenerateEvidence(fixedInput), iterations: 100);
}
[Fact]
[Requirement("REQ-TRACE-001")]
public void Test_TraceabilityComplete()
{
var requirementId = "REQ-EVIDENCE-001";
var testId = "MyTests.TestMethod";
var artifactHash = EvidenceChainAssert.ComputeSha256(artifact);
// Verify all traceability components present
EvidenceChainAssert.TraceabilityComplete(requirementId, testId, artifactHash);
}
```
**Traceability Report Generation:**
```csharp
using StellaOps.TestKit.Evidence;
// Generate traceability matrix from test assemblies
var reporter = new EvidenceChainReporter();
reporter.AddAssembly(typeof(MyTests).Assembly);
var report = reporter.GenerateReport();
// Output as Markdown
Console.WriteLine(report.ToMarkdown());
// Output as JSON
Console.WriteLine(report.ToJson());
```
**API Reference:**
- `RequirementAttribute(string requirementId)` - Link test to requirement
- `RequirementAttribute.SprintTaskId` - Link to sprint task (optional)
- `RequirementAttribute.ComplianceControl` - Link to compliance control (optional)
- `EvidenceChainAssert.ArtifactHashStable(artifact, expectedHash)` - Verify hash

- `Interop` - Cross-version compatibility tests (Turn #6)
---
### 12. Post-Incident Testing (Turn #6)
Generate regression tests from production incidents:
**Generate Test Scaffold from Incident:**
```csharp
using StellaOps.TestKit.Incident;
// Create incident metadata
var metadata = new IncidentMetadata
{
IncidentId = "INC-2026-001",
OccurredAt = DateTimeOffset.Parse("2026-01-15T10:30:00Z"),
RootCause = "Race condition in concurrent bundle creation",
AffectedModules = ["EvidenceLocker", "Policy"],
Severity = IncidentSeverity.P1,
Title = "Evidence bundle duplication"
};
// Generate test scaffold from replay manifest
var generator = new IncidentTestGenerator();
var scaffold = generator.GenerateFromManifestJson(manifestJson, metadata);
// Output generated test code
var code = scaffold.GenerateTestCode();
File.WriteAllText($"Tests/{scaffold.TestClassName}.cs", code);
```
**Generated Test Structure:**
```csharp
[Trait("Category", TestCategories.PostIncident)]
[Trait("Incident", "INC-2026-001")]
[Trait("Severity", "P1")]
public sealed class Incident_INC_2026_001_Tests
{
[Fact]
public async Task Validates_RaceCondition_Fix()
{
// Arrange - fixtures from replay manifest
// Act - execute the incident scenario
// Assert - verify fix prevents recurrence
}
}
```
**Filter Post-Incident Tests:**
```bash
# Run all post-incident tests
dotnet test --filter "Category=PostIncident"
# Run only P1/P2 tests (release-gating)
dotnet test --filter "Category=PostIncident&(Severity=P1|Severity=P2)"
# Run tests for a specific incident
dotnet test --filter "Incident=INC-2026-001"
```
**API Reference:**
- `IncidentMetadata` - Incident context (ID, severity, root cause, modules)
- `IncidentSeverity` - P1 (critical) through P4 (low impact)
- `IncidentTestGenerator.GenerateFromManifestJson(json, metadata)` - Generate scaffold
- `TestScaffold.GenerateTestCode()` - Output C# test code
- `TestScaffold.ToJson()` / `FromJson()` - Serialize/deserialize scaffold
- `IncidentTestGenerator.GenerateReport()` - Summary of registered incident tests
See [Post-Incident Testing Guide](post-incident-testing-guide.md) for complete documentation.

# Stella Ops Release {{VERSION}} - Verification Guide
This bundle contains everything needed to verify the authenticity and integrity
of Stella Ops release {{VERSION}} in an air-gapped environment.
## Quick Verification (requires cosign)
```bash
./verify.sh
```
Or on Windows (PowerShell 7+):
```powershell
./verify.ps1
```
## Manual Verification
### 1. Verify Checksums
Verify all artifacts match their expected checksums:
```bash
cd artifacts/
sha256sum -c ../checksums/SHA256SUMS
```
On Windows:
```powershell
Get-Content ..\checksums\SHA256SUMS | ForEach-Object {
$parts = $_ -split '\s+', 2
$expected = $parts[0]
$file = $parts[1]
$computed = (Get-FileHash -Path $file -Algorithm SHA256).Hash.ToLower()
if ($computed -eq $expected) {
Write-Host "[PASS] $file" -ForegroundColor Green
} else {
Write-Host "[FAIL] $file" -ForegroundColor Red
}
}
```
### 2. Verify Checksums Signature (requires cosign)
Verify that the checksums file was signed by Stella Ops:
```bash
cosign verify-blob \
--key cosign.pub \
--signature checksums/SHA256SUMS.sig \
checksums/SHA256SUMS
```
### 3. Verify Individual Artifact Signatures
```bash
# For each artifact
cosign verify-blob \
--key cosign.pub \
--signature artifacts/stella-{{VERSION}}-linux-x64.tar.gz.sig \
artifacts/stella-{{VERSION}}-linux-x64.tar.gz
```
### 4. Verify Provenance (SLSA)
Verify that the SLSA provenance statement was signed and inspect its contents:
```bash
# Verify signature
cosign verify-blob \
--key cosign.pub \
--signature provenance/stella-cli.slsa.intoto.jsonl.sig \
provenance/stella-cli.slsa.intoto.jsonl
# Inspect provenance contents
cat provenance/stella-cli.slsa.intoto.jsonl | jq .
```
The provenance should show:
- **Builder ID**: `https://ci.stella-ops.org/builder/v1`
- **Source commit**: `{{SOURCE_COMMIT}}`
- **Build timestamp**: Matches release time
- **Materials**: Lists all build inputs with digests
### 5. Verify SBOMs
```bash
# Verify SBOM signature
cosign verify-blob \
--key cosign.pub \
--signature sbom/stella-cli.cdx.json.sig \
sbom/stella-cli.cdx.json
# Inspect SBOM (requires jq or any JSON viewer)
cat sbom/stella-cli.cdx.json | jq '.components | length'
```
## Transparency Log Verification (requires network)
If you have network access, you can verify the artifacts were recorded in the
Rekor transparency log:
```bash
rekor-cli verify \
--artifact artifacts/stella-{{VERSION}}-linux-x64.tar.gz \
--signature artifacts/stella-{{VERSION}}-linux-x64.tar.gz.sig \
--public-key cosign.pub
```
### Rekor Log Entries
The following Rekor log entries are associated with this release:
{{REKOR_ENTRIES}}
You can look up any entry:
```bash
rekor-cli get --uuid <UUID>
```
## Offline Rekor Proof Verification
If Rekor proofs are included in this bundle (in `rekor-proofs/`), you can verify
Merkle inclusion proofs without network access:
```bash
# Verify inclusion proof (advanced)
# See: https://docs.sigstore.dev/verification/offline/
```
## Bundle Contents
| Path | Description |
|------|-------------|
| `cosign.pub` | Stella Ops signing public key |
| `rekor-public-key.pub` | Rekor transparency log public key (if included) |
| `checksums/SHA256SUMS` | SHA-256 checksums for all artifacts |
| `checksums/SHA256SUMS.sig` | Cosign signature of checksums |
| `checksums/SHA512SUMS` | SHA-512 checksums (optional) |
| `artifacts/` | Release binaries and archives |
| `sbom/` | Software Bill of Materials (CycloneDX) |
| `provenance/` | SLSA provenance statements (in-toto) |
| `attestations/` | Additional DSSE attestations |
| `rekor-proofs/` | Transparency log inclusion proofs |
| `manifest.json` | Bundle manifest with all file hashes |
## Signing Identity
| Property | Value |
|----------|-------|
| **Signing Method** | Cosign (keyless via Fulcio / key-based) |
| **Public Key Fingerprint** | `{{KEY_FINGERPRINT}}` |
| **Rekor Log ID** | `{{REKOR_LOG_ID}}` |
| **Certificate OIDC Issuer** | `https://oauth2.sigstore.dev/auth` |
| **Certificate Identity** | `https://ci.stella-ops.org` |
## Build Reproducibility
This release was built with deterministic settings:
| Property | Value |
|----------|-------|
| **SOURCE_DATE_EPOCH** | `{{SOURCE_DATE_EPOCH}}` |
| **Source Commit** | `{{SOURCE_COMMIT}}` |
| **.NET SDK Version** | See `global.json` |
| **Build Configuration** | Release |
To reproduce the build:
```bash
git clone https://git.stella-ops.org/stella-ops.org/git.stella-ops.org.git
cd git.stella-ops.org
git checkout {{SOURCE_COMMIT}}
export SOURCE_DATE_EPOCH={{SOURCE_DATE_EPOCH}}
make release
# Compare checksums
sha256sum dist/* | diff - <(cat path/to/evidence-pack/checksums/SHA256SUMS)
```
## Troubleshooting
### "cosign: command not found"
Install cosign:
- macOS: `brew install cosign`
- Linux: Download from https://github.com/sigstore/cosign/releases
- Windows: Download from https://github.com/sigstore/cosign/releases
### "Error: no matching signatures"
Ensure you're using the `cosign.pub` file from this bundle, not a different key.
### Checksum mismatch
If checksums don't match:
1. Re-download the artifact
2. Verify the download completed successfully
3. Check for file corruption during transfer
### Certificate verification failed
For keyless-signed artifacts, you may need to specify the expected identity:
```bash
cosign verify-blob \
--certificate-identity "https://ci.stella-ops.org" \
--certificate-oidc-issuer "https://oauth2.sigstore.dev/auth" \
--signature artifact.sig \
artifact
```
