## Execution Log
|
||||
| Date (UTC) | Update | Owner |
|
||||
| --- | --- | --- |
|
||||
| 2025-12-26 | Sprint created from product advisory analysis; consolidates diff-aware release gate requirements. | Project Mgmt |
|
||||
| 2025-12-26 | CICD-GATE-01, CICD-GATE-04 DONE. Created GateEndpoints.cs and GateContracts.cs with POST /api/v1/policy/gate/evaluate endpoint. Defined GateStatus enum and GateExitCodes constants (0=Pass, 1=Warn, 2=Fail). | Impl |
|
||||
| 2025-12-26 | BLOCKED: Policy.Gateway build fails due to pre-existing errors in PostgresBudgetStore.cs (missing RiskBudget, BudgetEntry, IBudgetStore types from incomplete sprint). New gate files compile successfully when isolated. | Impl |
|
||||
| 2025-12-26 | UNBLOCKED: Fixed pre-existing build errors in Policy.Storage.Postgres (ServiceCollectionExtensions interface alias), Telemetry.Core (TagList using), Replay.Core (duplicate CompressionAlgorithm, missing interface methods, Span conversions), and Policy.Engine (OperationalContext/MitigationFactors property mapping). Policy.Gateway now builds successfully. | Impl |
|
||||
| 2025-12-26 | CICD-GATE-02 DONE. Created RegistryWebhookEndpoints.cs with Docker Registry v2, Harbor, and generic webhook handlers at /api/v1/webhooks/registry/*. Created InMemoryGateEvaluationQueue.cs with Channel-based async queue and GateEvaluationWorker background service. Fixed duplicate IBudgetStore interface (consolidated in BudgetLedger.cs with ListAsync method). | Impl |
|
||||
| 2025-12-26 | CICD-GATE-05 DONE. Created GateCommandGroup.cs with `stella gate evaluate` and `stella gate status` commands. Supports --image, --baseline, --policy, --allow-override, --justification options. Returns GateExitCodes (0=Pass, 1=Warn, 2=Fail, 10+=errors). Outputs table/JSON formats via Spectre.Console. Registered in CommandFactory.cs. | Impl |
|
||||
| 2025-12-26 | CICD-GATE-06 DONE. Created GateBypassAuditEntry, IGateBypassAuditRepository, InMemoryGateBypassAuditRepository, and GateBypassAuditor service. Integrated into GateEndpoints to record bypasses with actor, justification, IP, and CI context. Includes rate limiting support. | Impl |
|
||||
| 2025-12-26 | CICD-GATE-07, CICD-GATE-08 DONE. Created GitHub Actions example workflow (.github/workflows/stellaops-gate-example.yml) and GitLab CI example (deploy/gitlab/stellaops-gate-example.gitlab-ci.yml). Both demonstrate gate evaluation, baseline strategies, override workflows, and deployment gating. | Impl |
|
||||
| 2025-12-26 | Sprint archived. Core gate endpoint, CLI, webhook handlers, audit logging, and CI examples complete. Remaining tasks (CICD-GATE-03, 09, 10) are Scheduler integration and documentation - can be done in follow-up sprint. | Impl |
|
||||
|
||||
## Decisions & Risks
|
||||
- Decision needed: Should Warn status block CI by default or pass-through? Recommend: configurable per-environment.
|
||||
- Decision needed: Gate evaluation timeout for long-running reachability analysis. Recommend: 60s default, configurable.
|
||||
- Risk: High evaluation latency may slow CI pipelines. Mitigation: async evaluation with cached baseline snapshots.
|
||||
- Risk: Gate bypass abuse. Mitigation: audit logging + Authority scope enforcement for bypass permission.
|
||||
|
||||
## Next Checkpoints
|
||||
- 2025-12-30 | CICD-GATE-01 complete | Gate endpoint accepting requests |
|
||||
- 2026-01-03 | CICD-GATE-05 complete | CLI integration verified |
|
||||
- 2026-01-06 | CICD-GATE-09 complete | End-to-end integration tested |

# SPRINT_20251226_001_SIGNER_fulcio_keyless_client
|
||||
|
||||
**Sprint ID:** 20251226_001_SIGNER
|
||||
**Topic:** Fulcio Keyless Signing Client Implementation
|
||||
**Status:** PARTIAL (Core implementation complete, remaining tasks are integration tests and docs)
|
||||
**Priority:** P0 (Critical Path)
|
||||
**Created:** 2025-12-26
|
||||
**Working Directory:** `src/Signer/`
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Implement Sigstore Fulcio integration for keyless signing in CI/CD pipelines. This enables ephemeral X.509 certificates (~10 min TTL) obtained via OIDC identity tokens, eliminating the need for persistent signing keys in CI environments while maintaining cryptographic non-repudiation through Rekor transparency logging.
|
||||
|
||||
**Business Value:**
|
||||
- Zero key management overhead in CI pipelines
|
||||
- Eliminates credential sprawl and secret rotation complexity
|
||||
- Enables audit-grade non-repudiation via OIDC identity binding
|
||||
- Aligns with Sigstore industry standard (adopted by Kubernetes, npm, PyPI)
|
||||
|
||||
**Dependencies:**
|
||||
- Attestor module for Rekor submission (Sprint 20251226_002)
|
||||
- Authority module for OIDC token minting (existing)
|
||||
- RFC 8785 canonicalization (existing in `StellaOps.Canonicalization`)
|
||||
|
||||

|
||||
|
||||

||||
## Scope & Boundaries
|
||||
|
||||
### In Scope
|
||||

|
||||
- Certificate chain handling and validation
|
||||
- Integration with existing `IDsseSigner` interface
|
||||

|
||||
- Unit and integration tests
|
||||
|
||||
### Out of Scope
|
||||

|
||||
- Bundle rotation workflows (Sprint 002)
|
||||
- CLI integration (Sprint 003)

|
||||
- Certificate chains MUST validate to configured Fulcio roots
|
||||
- All timestamps in UTC ISO-8601

## Security Considerations
|
||||
|
||||
### Threat Model
|
||||
|
||||
| Threat | Mitigation |
|
||||
|--------|------------|
|
||||
| Private key theft | Keys exist only in memory, zeroed on disposal |
|
||||
| Fulcio impersonation | TLS certificate validation, root pinning |
|
||||
| OIDC token replay | Short-lived tokens, audience validation |
|
||||
| Certificate forgery | Chain validation to trusted Fulcio roots |
|
||||
| Timing attacks | Constant-time comparison for signatures |
|
||||
|
||||
### Security Checklist
|
||||
|
||||
- [ ] Ephemeral keys never written to disk or logs
|
||||
- [ ] Private key memory zeroed in Dispose() and finalizer
|
||||
- [ ] Fulcio TLS certificate validated
|
||||
- [ ] OIDC token audience matches expected value
|
||||
- [ ] Certificate chain validates to configured roots
|
||||
- [ ] SCT (Signed Certificate Timestamp) verified when required
|
||||
- [ ] No secrets in configuration (use refs: `env:`, `file:`, `vault:`)

## Decisions & Risks
|
||||
|
||||
| ID | Decision/Risk | Status | Owner | Notes |
|
||||
|----|---------------|--------|-------|-------|
|
||||
| D001 | Use ECDSA P-256 as default algorithm | DECIDED | — | Widest compatibility, Fulcio default |
|
||||
| D002 | Support Ed25519 as alternative | DECIDED | — | Better performance, growing adoption |
|
||||
| R001 | Fulcio availability dependency | OPEN | — | Mitigate with retries, circuit breaker, fallback to KMS |
|
||||
| R002 | OIDC token acquisition latency | OPEN | — | Cache tokens, refresh proactively |
|
||||
| R003 | Air-gap incompatibility | ACCEPTED | — | Keyless requires network; use KMS mode for air-gap |

### Identity Constraint Documentation
|
||||
|
||||
```markdown
|
||||
# docs/guides/identity-constraints.md
|
||||
|
||||
# Identity Constraints for Keyless Verification
|
||||
|
||||
## Overview
|
||||
|
||||
Keyless signing binds attestations to OIDC identities. During verification,
|
||||
you must specify which identities are trusted using two key constraints:
|
||||
|
||||
1. **Certificate Identity** (`--certificate-identity`): The subject or SAN
|
||||
2. **Certificate OIDC Issuer** (`--certificate-oidc-issuer`): The token issuer
|
||||
|
||||
## Platform-Specific Patterns
|
||||
|
||||
### GitHub Actions
|
||||
|
||||
| Constraint | Pattern | Example |
|
||||
|------------|---------|---------|
|
||||
| Repository | `repo:<owner>/<repo>:.*` | `repo:stella-ops/scanner:.*` |
|
||||
| Branch | `repo:<owner>/<repo>:ref:refs/heads/<branch>` | `repo:stella-ops/scanner:ref:refs/heads/main` |
|
||||
| Tag | `repo:<owner>/<repo>:ref:refs/tags/.*` | `repo:stella-ops/scanner:ref:refs/tags/v.*` |
|
||||
| Environment | `repo:<owner>/<repo>:environment:<env>` | `repo:stella-ops/scanner:environment:production` |
|
||||
| Workflow | (in SAN) | `.github/workflows/release.yml@refs/heads/main` |
|
||||
|
||||
**OIDC Issuer:** `https://token.actions.githubusercontent.com`
|
||||
|
||||
### GitLab CI
|
||||
|
||||
| Constraint | Pattern | Example |
|
||||
|------------|---------|---------|
|
||||
| Project | `project_path:<group>/<project>:.*` | `project_path:stellaops/scanner:.*` |
|
||||
| Branch | `project_path:<group>/<project>:ref_type:branch:ref:<branch>` | `...:ref_type:branch:ref:main` |
|
||||
| Tag | `project_path:<group>/<project>:ref_type:tag:ref:.*` | `...:ref_type:tag:ref:v.*` |
|
||||
| Protected | `project_path:<group>/<project>:ref_protected:true` | N/A |
|
||||
|
||||
**OIDC Issuer:** `https://gitlab.com` (or self-hosted URL)
|
||||
|
||||
### Best Practices
|
||||
|
||||
1. **Always constrain to repository**: Never accept `.*` as the full identity
|
||||
2. **Prefer branch constraints for production**: Use `ref:refs/heads/main`
|
||||
3. **Use environment constraints when available**: More granular than branches
|
||||
4. **Combine with Rekor verification**: `--require-rekor` ensures transparency
|
||||
5. **Rotate issuer trust carefully**: Changes affect all verification
|
||||
```
|
||||

## Testing Requirements
|
||||
|
||||
### Template Validation Tests
|
||||
|
||||
```yaml
|
||||
# Test: GitHub Actions template syntax
|
||||
- name: Validate GitHub workflow
|
||||
run: |
|
||||
# Use actionlint for validation
|
||||
actionlint .github/workflows/examples/*.yml
|
||||
|
||||
# Test: GitLab CI template syntax
|
||||
- name: Validate GitLab CI
|
||||
run: |
|
||||
# Use gitlab-ci-lint
|
||||
gitlab-ci-lint deploy/gitlab/examples/.gitlab-ci-stellaops.yml
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
|
||||
| Test | Platform | Description |
|
||||
|------|----------|-------------|
|
||||
| `github-sign-verify` | GitHub | Sign in one workflow, verify in another |
|
||||
| `gitlab-sign-verify` | GitLab | Sign in one job, verify in deployment job |
|
||||
| `gitea-release` | Gitea | Sign release, verify before publish |
|
||||
| `cross-platform` | All | Sign in GitHub, verify in GitLab |
|
||||
|
||||
### Test Repository Structure
|
||||
|
||||
```
|
||||

|
||||
├── github/
|
||||

||||
**Status:** DONE
|
||||
|
||||
## Topic & Scope
|
||||
- Build PM-facing Angular 17 dashboard for risk budget visualization and delta verdict display.
|
||||
- Implement burn-up charts, verdict badges, evidence drill-downs, and exception management UI.
|
||||
- Deliver side-by-side diff visualization for before/after risk comparison.
|
||||
- **Working directory:** `src/Web/StellaOps.Web`
|
||||
|
||||
## Dependencies & Concurrency
|
||||
- Depends on: SPRINT_20251226_001_BE (gate API endpoints), SPRINT_20251226_002_BE (budget API), SPRINT_20251226_003_BE (exception API).
|
||||
- Can run in parallel with: SPRINT_20251226_005_SCANNER (reachability extractors).
|
||||
- Blocked by: Backend API endpoints must be complete before full integration.
|
||||
|
||||

## Decisions & Risks
|
||||
- Decision needed: Chart library for burn-up visualization. Recommend: ngx-charts or Chart.js (already in use?).
|
||||
- Decision needed: Mini-graph library for reachability slice. Recommend: D3.js or Cytoscape.js.
|
||||
- Decision needed: Mobile support scope. Recommend: tablet minimum, phone deferred.
|
||||
- Risk: Large diff graphs may cause performance issues. Mitigation: "changed neighborhood only" default view, progressive loading.
|
||||
- Risk: Evidence panel latency for large SBOMs. Mitigation: paginated loading, summary-first approach.
