# Additional Community Plugin Grant - StellaOps Addendum to BUSL-1.1
|
||||||
|
|
||||||
|
**Addendum Version:** 1.0.0
|
||||||
|
**Effective Date:** 2026-01-25
|
||||||
|
**Licensor:** stella-ops.org
|
||||||
|
|
||||||
|
This Addendum supplements the Business Source License 1.1 (BUSL-1.1) under which
|
||||||
|
Stella Ops Suite is licensed. Where this Addendum conflicts with BUSL-1.1, this
|
||||||
|
Addendum controls for the specific grants below.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. Definitions
|
||||||
|
|
||||||
|
For purposes of this Addendum:
|
||||||
|
|
||||||
|
(a) **"Plugin"** means a separately packaged extension written to interface with the
|
||||||
|
Licensed Work using documented public plugin APIs or integration points published
|
||||||
|
by Licensor. A Plugin may include connectors, integrations, analyzers, formatters,
|
||||||
|
or other extensions that extend the Licensed Work's functionality without modifying
|
||||||
|
its core source code.
|
||||||
|
|
||||||
|
(b) **"Environment"** means an instance of the Licensed Work under the control of a
|
||||||
|
single legal entity (customer/organization) and deployed to a unique production
|
||||||
|
orchestration boundary. Examples include: a distinct on-premises cluster, a private
|
||||||
|
cloud tenant, or a named cloud account. For avoidance of doubt, dev/staging/production
|
||||||
|
deployments for the same organization each count as separate Environments.
|
||||||
|
|
||||||
|
(c) **"Scan"** means one completed execution of the Licensed Work's vulnerability or
|
||||||
|
artifact analysis pipeline that produces a report or SBOM/VEX output and is billed
|
||||||
|
or metered as a single unit by Licensor's published metrics. Cached or deduplicated
|
||||||
|
results that do not trigger new analysis do not count as additional Scans.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. Community Plugin Grant
|
||||||
|
|
||||||
|
Notwithstanding anything to the contrary in BUSL-1.1, Licensor hereby grants each
|
||||||
|
Recipient a worldwide, non-exclusive, royalty-free license to:
|
||||||
|
|
||||||
|
(i) **Use, run, and reproduce** a Plugin in production solely for the Recipient's
|
||||||
|
internal business operations in up to **three (3) Environments**; and
|
||||||
|
|
||||||
|
(ii) **Perform up to nine hundred ninety-nine (999) Scans per calendar day** across
|
||||||
|
all such Environments.
|
||||||
|
|
||||||
|
This grant extends to modification and redistribution of the Plugin under the same
|
||||||
|
terms, provided redistribution is not packaged with a commercial managed hosting
|
||||||
|
offering in breach of Section 4 below.
|
||||||
|
|
||||||
|
**Commercial Plugin Development.** You may develop and sell Plugins commercially under
|
||||||
|
license terms of your choosing, provided:
|
||||||
|
- The Plugin does not include, copy, or modify the Licensed Work's source code; AND
|
||||||
|
- Distribution complies with Section 3 below.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 3. Distribution & Attribution
|
||||||
|
|
||||||
|
Recipients may distribute Plugin source or binaries under the same license terms as
|
||||||
|
the Licensed Work (including this Addendum). Distributed copies must:
|
||||||
|
|
||||||
|
(a) **Retain conspicuous attribution** to Licensor, including the Licensor name and
|
||||||
|
a link to the Licensed Work's source repository;
|
||||||
|
|
||||||
|
(b) **Include this Addendum verbatim** alongside any distribution of the Licensed Work
|
||||||
|
or Plugins that incorporate portions of the Licensed Work;
|
||||||
|
|
||||||
|
(c) **Preserve the LICENSE and NOTICE files** from the original distribution.
|
||||||
|
|
||||||
|
**Competing Service Restriction.** Redistribution that embeds or repackages Licensor's
|
||||||
|
core runtime binaries into a commercial product that functions as a competing managed
|
||||||
|
service requires a separate commercial license from Licensor.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. SaaS / Managed Offering Restriction
|
||||||
|
|
||||||
|
Recipients are **NOT** permitted to offer the Licensed Work or a Plugin (or a service
|
||||||
|
that substantially replicates the Licensed Work's core features) as a commercial hosted
|
||||||
|
service, SaaS, or managed/white-label hosting offering to third parties without a
|
||||||
|
separate written commercial license from Licensor.
|
||||||
|
|
||||||
|
This restriction applies whether the service is offered:
|
||||||
|
- Directly to end customers;
|
||||||
|
- Via a reseller or channel partner; or
|
||||||
|
- Embedded into a larger multi-tenant managed platform.
|
||||||
|
|
||||||
|
**Limited Exceptions:**
|
||||||
|
|
||||||
|
(a) **Internal Hosting.** An organization may host the Licensed Work internally for
|
||||||
|
its own employees, contractors, and affiliates without a commercial license,
|
||||||
|
subject to the Environment and Scan limits in Section 2.
|
||||||
|
|
||||||
|
(b) **MSP Single-Tenant Hosting.** A Managed Service Provider (MSP) may host distinct
|
||||||
|
single-tenant instances per customer only if:
|
||||||
|
- Each hosted instance is covered by the MSP's commercial license; OR
|
||||||
|
- The hosted instance remains fully isolated and used exclusively by the
|
||||||
|
licensee's employees and affiliates.
|
||||||
|
|
||||||
|
(c) **Public multi-tenant paid hosting** that provides the Licensed Work's functionality
|
||||||
|
to unrelated third parties is **prohibited** under this Addendum absent a commercial
|
||||||
|
license.
|
||||||
|
|
||||||
|
(d) **Non-Commercial Community Hosting.** Non-commercial, free-of-charge hosting for
|
||||||
|
community benefit (e.g., providing scanning services to open source projects) may
|
||||||
|
be permitted under a separate community program. Organizations wishing to provide
|
||||||
|
such services should contact Licensor at community@stella-ops.org for evaluation.
|
||||||
|
Approval is not automatic and is subject to Licensor's community program terms.
|
||||||
|
|
||||||
|
For detailed guidance on MSP and SaaS scenarios, see `docs/legal/SAAS_MSP_GUIDANCE.md`.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 5. Enforcement & Telemetry
|
||||||
|
|
||||||
|
Licensor may reasonably audit or require self-reporting to verify compliance with the
|
||||||
|
Environment and Scan limits described in this Addendum.
|
||||||
|
|
||||||
|
**Audit Rights.** Licensor reserves the right to request compliance verification no
|
||||||
|
more than once per calendar year, with reasonable notice (minimum 30 days). Any audit
|
||||||
|
shall be:
|
||||||
|
- Conducted during normal business hours;
|
||||||
|
- Subject to standard confidentiality and data-protection safeguards; and
|
||||||
|
- Limited in scope to verification of Environment count and Scan volume.
|
||||||
|
|
||||||
|
**Voluntary Telemetry.** Licensor may provide an optional, privacy-respecting metering
|
||||||
|
endpoint for voluntary telemetry. Such telemetry:
|
||||||
|
- Is strictly opt-in;
|
||||||
|
- Collects only aggregate usage metrics (Environment count, Scan count);
|
||||||
|
- Does not collect customer content, source code, or scan results; and
|
||||||
|
- Is subject to Licensor's published privacy policy.
|
||||||
|
|
||||||
|
**Self-Attestation.** Recipients may provide annual self-attestation of compliance
|
||||||
|
using the form at `docs/legal/templates/self-attestation-form.md`.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 6. Term & Upgrade
|
||||||
|
|
||||||
|
This Addendum applies to releases of the Licensed Work that include it. Licensor may
|
||||||
|
amend the numeric limits (Environments / Scans) by publishing a new Addendum version.
|
||||||
|
|
||||||
|
**Non-Retroactive Changes.** Such changes do not retroactively affect prior
|
||||||
|
distributions. Recipients using a version of the Licensed Work with an earlier
|
||||||
|
Addendum version may continue under those terms for that version.
|
||||||
|
|
||||||
|
**Version Identification.** Each Addendum version is identified by the version number
|
||||||
|
in the header. The applicable Addendum version for any distribution is the version
|
||||||
|
included with that distribution.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 7. No Waiver of Other BUSL Rights
|
||||||
|
|
||||||
|
Except as explicitly modified by this Addendum, all terms of BUSL-1.1 remain in full
|
||||||
|
force and effect, including but not limited to:
|
||||||
|
- The Change Date and Change License provisions;
|
||||||
|
- The requirement to preserve license and attribution notices;
|
||||||
|
- The disclaimer of warranties and limitation of liability.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 8. Legal & Compliance Notice
|
||||||
|
|
||||||
|
This Addendum is intended as a narrow community grant to encourage plugin ecosystems
|
||||||
|
while protecting Licensor's commercial SaaS market. It is not legal advice and should
|
||||||
|
be reviewed by counsel prior to publication or reliance.
|
||||||
|
|
||||||
|
**Governing Law.** This Addendum is governed by the same jurisdiction and governing
|
||||||
|
law provisions as the underlying BUSL-1.1 license.
|
||||||
|
|
||||||
|
**Severability.** If any provision of this Addendum is held unenforceable, the
|
||||||
|
remaining provisions continue in full force and effect.

# Tile Proxy Docker Compose
|
||||||
|
|
||||||
|
This directory contains the Docker Compose configuration for deploying the StellaOps Tile Proxy service.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
The Tile Proxy acts as a caching intermediary between StellaOps clients and upstream Rekor transparency logs. It provides:
|
||||||
|
|
||||||
|
- **Tile Caching**: Caches tiles locally for faster subsequent requests
|
||||||
|
- **Request Coalescing**: Deduplicates concurrent requests for the same tile
|
||||||
|
- **Offline Support**: Serves from cache when upstream is unavailable
|
||||||
|
- **TUF Integration**: Optional validation using TUF trust anchors
|
||||||
|
|
||||||
|
## Quick Start
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Start with default configuration
|
||||||
|
docker compose up -d
|
||||||
|
|
||||||
|
# Check health
|
||||||
|
curl http://localhost:8090/_admin/health
|
||||||
|
|
||||||
|
# View cache statistics
|
||||||
|
curl http://localhost:8090/_admin/cache/stats
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Integration with StellaOps
|
||||||
|
|
||||||
|
Configure your StellaOps Attestor to use the tile proxy:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
attestor:
|
||||||
|
rekor:
|
||||||
|
url: http://tile-proxy:8080
|
||||||
|
# or if running standalone:
|
||||||
|
# url: http://localhost:8090
|
||||||
|
```
|
||||||
|
|
||||||
|
## Monitoring
|
||||||
|
|
||||||
|
### Prometheus Metrics
|
||||||
|
|
||||||
|
The tile proxy exposes metrics at `/_admin/metrics`:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
curl http://localhost:8090/_admin/metrics
|
||||||
|
```
|
||||||
|
|
||||||
|
Example response:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"cacheHits": 12450,
|
||||||
|
"cacheMisses": 234,
|
||||||
|
"hitRatePercent": 98.15,
|
||||||
|
"upstreamRequests": 234,
|
||||||
|
"upstreamErrors": 2,
|
||||||
|
"inflightRequests": 0
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Health Checks
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Liveness (is the service running?)
|
||||||
|
curl http://localhost:8090/_admin/health
|
||||||
|
|
||||||
|
# Readiness (can it serve requests?)
|
||||||
|
curl http://localhost:8090/_admin/ready
|
||||||
|
```
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Cache is not being used
|
||||||
|
|
||||||
|
1. Check cache stats: `curl http://localhost:8090/_admin/cache/stats`
|
||||||
|
2. Verify cache volume is mounted correctly
|
||||||
|
3. Check logs for write errors
|
||||||
|
|
||||||
|
### Upstream connection failures
|
||||||
|
|
||||||
|
1. Check network connectivity to upstream
|
||||||
|
2. Verify `REKOR_UPSTREAM_URL` is correct
|
||||||
|
3. Check for firewall/proxy issues
|
||||||
|
|
||||||
|
### High memory usage
|
||||||
|
|
||||||
|
1. Reduce `CACHE_MAX_SIZE_GB`
|
||||||
|
2. Trigger manual prune: `curl -X DELETE http://localhost:8090/_admin/cache/prune?targetSizeBytes=5368709120`
|
||||||
|
|
||||||
|

# Stella TUF Trust Repository Template
|
||||||
|
|
||||||
|
This directory contains a template for creating a TUF (The Update Framework) repository
|
||||||
|
for distributing trust anchors to StellaOps clients.
|
||||||
|
|
||||||
|
## WARNING
|
||||||
|
|
||||||
|
**The sample keys in this template are for DEMONSTRATION ONLY.**
|
||||||
|
**DO NOT USE THESE KEYS IN PRODUCTION.**
|
||||||
|
|
||||||
|
Generate new keys using the `scripts/init-tuf-repo.sh` script before deploying.
|
||||||
|
|
||||||
|
## Directory Structure
|
||||||
|
|
||||||
|
```
|
||||||
|
stella-trust/
|
||||||
|
├── root.json # Root metadata (rotates rarely, high ceremony)
|
||||||
|
├── snapshot.json # Current target versions
|
||||||
|
├── timestamp.json # Freshness indicator (rotates frequently)
|
||||||
|
├── targets.json # Target file metadata
|
||||||
|
└── targets/
|
||||||
|
├── rekor-key-v1.pub # Rekor log public key
|
||||||
|
├── fulcio-chain.pem # Fulcio certificate chain
|
||||||
|
└── sigstore-services-v1.json # Service endpoint map
|
||||||
|
```
|
||||||
|
|
||||||
|
## Quick Start
|
||||||
|
|
||||||
|
### 1. Initialize a New Repository
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Generate new signing keys (do this in a secure environment)
|
||||||
|
./scripts/init-tuf-repo.sh /path/to/new-repo
|
||||||
|
|
||||||
|
# This creates:
|
||||||
|
# - Root key (keep offline, backup securely)
|
||||||
|
# - Snapshot key
|
||||||
|
# - Timestamp key
|
||||||
|
# - Targets key
|
||||||
|
# - Initial metadata files
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Add a Target
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Add Rekor public key as a target
|
||||||
|
./scripts/add-target.sh /path/to/rekor-key.pub rekor-key-v1
|
||||||
|
|
||||||
|
# Add service map
|
||||||
|
./scripts/add-target.sh /path/to/sigstore-services.json sigstore-services-v1
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Publish Updates
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Update timestamp (do this regularly, e.g., daily)
|
||||||
|
./scripts/update-timestamp.sh
|
||||||
|
|
||||||
|
# The timestamp.json should be refreshed frequently to maintain client trust
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4. Deploy
|
||||||
|
|
||||||
|
Host the repository contents on a web server:
|
||||||
|
- HTTPS required for production
|
||||||
|
- Set appropriate cache headers (short TTL for timestamp.json)
|
||||||
|
- Consider CDN for global distribution
|
||||||
|
|
||||||
|
## Key Management
|
||||||
|
|
||||||
|
### Key Hierarchy
|
||||||
|
|
||||||
|
```
|
||||||
|
Root Key (offline, high ceremony)
|
||||||
|
├── Snapshot Key (can be online)
|
||||||
|
├── Timestamp Key (must be online for automation)
|
||||||
|
└── Targets Key (can be online)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Security Recommendations
|
||||||
|
|
||||||
|
1. **Root Key**: Store offline in HSM or air-gapped system. Only use for:
|
||||||
|
- Initial repository creation
|
||||||
|
- Root key rotation (rare)
|
||||||
|
- Emergency recovery
|
||||||
|
|
||||||
|
2. **Snapshot/Targets Keys**: Can be stored in secure KMS for automation.
|
||||||
|
|
||||||
|
3. **Timestamp Key**: Must be accessible for automated updates. Use short-lived
|
||||||
|
credentials and rotate regularly.
|
||||||
|
|
||||||
|
### Key Rotation
|
||||||
|
|
||||||
|
See `docs/operations/key-rotation-runbook.md` for detailed procedures.
|
||||||
|
|
||||||
|
Quick rotation example:
|
||||||
|
```bash
|
||||||
|
# Add new key while keeping old one active
|
||||||
|
./scripts/rotate-key.sh targets --add-key /path/to/new-key.pub
|
||||||
|
|
||||||
|
# After grace period (clients have updated), remove old key
|
||||||
|
./scripts/rotate-key.sh targets --remove-key old-key-id
|
||||||
|
```
|
||||||
|
|
||||||
|
## Client Configuration
|
||||||
|
|
||||||
|
Configure StellaOps clients to use your TUF repository:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
attestor:
|
||||||
|
trust_repo:
|
||||||
|
enabled: true
|
||||||
|
tuf_url: https://trust.yourcompany.com/tuf/
|
||||||
|
service_map_target: sigstore-services-v1
|
||||||
|
rekor_key_targets:
|
||||||
|
- rekor-key-v1
|
||||||
|
```
|
||||||
|
|
||||||
|
Or via CLI:
|
||||||
|
```bash
|
||||||
|
stella trust init \
|
||||||
|
--tuf-url https://trust.yourcompany.com/tuf/ \
|
||||||
|
--service-map sigstore-services-v1 \
|
||||||
|
--pin rekor-key-v1
|
||||||
|
```
|
||||||
|
|
||||||
|
## Metadata Expiration
|
||||||
|
|
||||||
|
Default expiration times (configurable in init script):
|
||||||
|
- `root.json`: 365 days
|
||||||
|
- `snapshot.json`: 7 days
|
||||||
|
- `timestamp.json`: 1 day
|
||||||
|
- `targets.json`: 30 days
|
||||||
|
|
||||||
|
Clients will refuse to use metadata past its expiration. Ensure automated
|
||||||
|
timestamp updates are running.
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Client reports "metadata expired"
|
||||||
|
The timestamp.json hasn't been updated. Run:
|
||||||
|
```bash
|
||||||
|
./scripts/update-timestamp.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
### Client reports "signature verification failed"
|
||||||
|
Keys may have rotated without client update. Client should run:
|
||||||
|
```bash
|
||||||
|
stella trust sync --force
|
||||||
|
```
|
||||||
|
|
||||||
|
### Client reports "unknown target"
|
||||||
|
Target hasn't been added to repository. Add it:
|
||||||
|
```bash
|
||||||
|
./scripts/add-target.sh /path/to/target target-name
|
||||||
|
```

# Sprint 20260125_001 — TUF Trust Foundation
|
||||||
|
|
||||||
|
## Topic & Scope
|
||||||
|
- Implement TUF (The Update Framework) client library for trust metadata distribution
|
||||||
|
- Eliminate hardcoded Sigstore endpoints and public keys in favor of versioned TUF targets
|
||||||
|
- Enable automatic trust metadata refresh with configurable freshness windows
|
||||||
|
- Working directory: `src/Attestor/`
|
||||||
|
- Expected evidence: TUF client library, service map schema, integration tests, docs
|
||||||
|
|
||||||
|
## Dependencies & Concurrency
|
||||||
|
- No upstream sprint dependencies
|
||||||
|
- Can run in parallel with existing Attestor work (non-breaking additions)
|
||||||
|
- Must coordinate with AirGap module for offline TUF metadata bundling (SPRINT_20260125_002)
|
||||||
|
|
||||||
|
## Documentation Prerequisites
|
||||||
|
- Read: `docs/modules/attestor/rekor-verification-design.md` (current trust root handling)
|
||||||
|
- Read: `docs/security/trust-and-signing.md` (existing TUF guidance)
|
||||||
|
- Read: `docs/modules/airgap/guides/portable-evidence-bundle-verification.md` (offline verification)
|
||||||
|
- Reference: [TUF Specification](https://theupdateframework.github.io/specification/latest/)
|
||||||
|
- Reference: [C2SP tlog-tiles](https://c2sp.org/tlog-tiles)
|
||||||
|
|
||||||
|
## Delivery Tracker
|
||||||
|
|
||||||
|
### TUF-001 - Define sigstore-services.json schema
|
||||||
|
Status: DONE
|
||||||
|
Dependency: none
|
||||||
|
Owners: Developer
|
||||||
|
|
||||||
|
Task description:
|
||||||
|
Create JSON schema for the Sigstore service map target. This file will be distributed via TUF and contains:
|
||||||
|
- Canonical Rekor endpoint URL
|
||||||
|
- Canonical Fulcio endpoint URL (for keyless signing)
|
||||||
|
- CT log URLs (optional)
|
||||||
|
- Site-local override mechanism
|
||||||
|
- Schema version for forward compatibility
|
||||||
|
|
||||||
|
File location: `docs/contracts/sigstore-services.schema.json`
|
||||||
|
|
||||||
|
Completion criteria:
|
||||||
|
- [x] JSON schema defined with required/optional fields
|
||||||
|
- [x] Example `sigstore-services.json` created with Sigstore production values
|
||||||
|
- [x] Schema supports site-local overrides via `overrides` block
|
||||||
|
- [x] Version field included for schema evolution
|

### TUF-002 - Implement TUF client library
|
||||||
|
Status: DONE
|
||||||
|
Dependency: TUF-001
|
||||||
|
Owners: Developer
|
||||||
|
|
||||||
|
Task description:
|
||||||
|
Create `StellaOps.Attestor.TrustRepo` library implementing a TUF client. The client must:
|
||||||
|
- Parse and validate TUF metadata (root.json, snapshot.json, timestamp.json, targets.json)
|
||||||
|
- Support role-based delegation for targets
|
||||||
|
- Verify metadata signatures (Ed25519, ECDSA P-256)
|
||||||
|
- Track metadata freshness with configurable expiration thresholds
|
||||||
|
- Support both online refresh and offline (bundled) mode
|
||||||
|
- Cache metadata locally with atomic writes
|
||||||
|
|
||||||
|
Implementation approach:
|
||||||
|
- Create `ITufClient` interface with `RefreshAsync()`, `GetTargetAsync(string targetName)` methods
|
||||||
|
- Create `TufMetadataStore` for local caching (similar to `FileSystemRekorTileCache`)
|
||||||
|
- Create `TufMetadataVerifier` for signature validation
|
||||||
|
- Support `STELLA_TUF_ROOT_URL` environment variable for repository URL
|
||||||
|
|
||||||

## Decisions & Risks
|
||||||
|
- **Decision**: Use TUF 1.0 specification (stable, widely adopted)
|
||||||
|
- **Decision**: Support both Ed25519 and ECDSA P-256 for metadata signatures (alignment with Sigstore)
|
||||||
|
- **Risk**: TUF client adds dependency complexity; mitigate by keeping implementation minimal
|
||||||
|
- **Risk**: Organizations must operate TUF repository; mitigate by providing template and scripts
|
||||||
|
- **Decision**: Implemented TUF client from scratch for full control and minimal dependencies. Uses only System.Text.Json, Sodium.Core (for Ed25519), and standard .NET crypto.
|
||||||
|
|
||||||
|
## Next Checkpoints
|
||||||
|
- TUF-001 + TUF-002 complete: Demo TUF client fetching metadata
|
||||||
|
- TUF-004 complete: Demo Rekor verification using TUF-loaded keys

## Decisions & Risks
|
||||||
|
|
||||||
|
### Decisions Made
|
||||||
|
|
||||||
|
1. **Separate addendum file approach**: Created addendum as separate file rather than
|
||||||
|
modifying LICENSE directly. Rationale: allows independent versioning, maintains
|
||||||
|
BUSL-1.1 structure, enables non-retroactive updates per Section 6.
|
||||||
|
|
||||||
|
2. **Comprehensive FAQ structure**: Created detailed FAQ with 15+ questions rather than
|
||||||
|
minimal FAQ. Rationale: reduces support burden, provides clear guidance for edge cases.
|
||||||
|
|
||||||
|
3. **Templates directory**: Created `docs/legal/templates/` for fillable forms.
|
||||||
|
Rationale: separates process documentation from fillable artifacts.
|
||||||
|
|
||||||
|
4. **Non-commercial community hosting exception**: Added Section 4(d) to addendum and
|
||||||
|
expanded SAAS_MSP_GUIDANCE.md Section 4.3 to address non-paid hosting scenarios per
|
||||||
|
advisory language about "public multi-tenant **paid** hosting." Community Program
|
||||||
|
requires explicit approval from Licensor.
|
||||||
|
|
||||||
|
### Risks
|
||||||
|
|
||||||
|
1. **Legal review required**: All new addendum text requires legal counsel review before
|
||||||
|
public release. Status: Documented in addendum Section 8.
|
||||||
|
|
||||||
|
2. **CI integration deferred**: License audit workflow updates for addendum presence
|
||||||
|
check deferred to follow-up sprint.
|
||||||
|
|
||||||
|
## Next Checkpoints
|
||||||
|
|
||||||
|
- Legal review of addendum text (external counsel)
|
||||||
|
- CI workflow update for addendum validation (follow-up sprint if needed)
|
||||||
|
- Plugin developer documentation in `docs/plugins/` (separate sprint if needed)
|
||||||
|
|
||||||
|
## Files Created
|
||||||
|

|
||||||
|
| 2026-01-25 | All acceptance criteria verified. Sprint archived. | Claude |
|
||||||
|
|
||||||
|
## Decisions & Risks
|
||||||
|
- **Decision:** Reuse `verification-badge.component.ts` for DSSE pill rather than duplicate styling.
|
||||||
|
- **Decision:** Keep existing 4 pills (Reachability, Call-stack, Provenance, VEX) alongside new pills - configurable via input.
|
||||||
|
- **Risk:** API may not return all ribbon data in single call. Mitigation: Add `/evidence/{id}/summary` endpoint if needed.
|
||||||
|
- **Risk:** Pill overflow on narrow screens. Mitigation: Implement horizontal scroll or dropdown overflow menu.
|
||||||
|
|
||||||
|
## Next Checkpoints
|
||||||
|
- MVP demo: Evidence Ribbon with all 7 pills + Quick-Verify button.
|
||||||
|
- Integration test with Quick-Verify drawer (SPRINT_20260125_002).

# Sprint 20260125_002 — Trust Automation & Tile Proxy
|
||||||
|
|
||||||
|
## Topic & Scope
|
||||||
|
- Implement signer-proxy service for centralized tile caching and Sigstore traffic
|
||||||
|
- Add CLI commands for trust repository management (`stella-trust`)
|
||||||
|
- Create automated snapshot export job for air-gap bundle preparation
|
||||||
|
- Integrate service map with endpoint discovery
|
||||||
|
- Working directory: `src/Attestor/`, `src/Cli/`, `src/AirGap/`
|
||||||
|
- Expected evidence: Tile-proxy service, CLI commands, export job, integration tests
|
||||||
|
|
||||||
|
## Dependencies & Concurrency
|
||||||
|
- Depends on: SPRINT_20260125_001 (TUF Foundation) - TUF client and service map must exist
|
||||||
|
- Can partially overlap: TUF-002 must be complete before PROXY-002
|
||||||
|
- Parallel work possible: CLI commands (PROXY-003/004) can proceed independently
|
||||||
|
|
||||||
|
## Documentation Prerequisites
|
||||||
|
- Read: SPRINT_20260125_001 completion (TUF client, service map schema)
|
||||||
|
- Read: `docs/modules/attestor/rekor-verification-design.md` (tile caching design)
|
||||||
|
- Read: `docs/modules/airgap/guides/offline-bundle-format.md` (export format)
|
||||||
|
- Read: `src/Attestor/StellaOps.Attestor/StellaOps.Attestor.Core/Rekor/FileSystemRekorTileCache.cs` (existing cache)

## Decisions & Risks
|
||||||
|
- **Decision**: Use tar.zst for snapshot format (good compression, streaming support)
|
||||||
|
- **Decision**: Tile cache uses content-addressed paths (immutable, deduped)
|
||||||
|
- **Risk**: Tile-proxy adds operational complexity; mitigate with Docker Compose and docs
|
||||||
|
- **Risk**: Large tile caches may consume significant disk; implement LRU eviction
|
||||||
|
- **Open Question**: Should tile-proxy support authentication? Initial version will be unauthenticated (internal network assumption).
|
||||||
|
|
||||||
|
## Next Checkpoints
|
||||||
|
- PROXY-001 + PROXY-002 complete: Demo tile-proxy serving cached tiles
|
||||||
|
- PROXY-003 + PROXY-004 complete: Demo `stella trust export` creating bundle
|
||||||
|
- Sprint complete: Full roundtrip (export → import → verify offline) working

# Sprint 20260125_002 - Quick-Verify Drawer (MVP)
|
||||||
|
|
||||||
|
## Topic & Scope
|
||||||
|
- Create right-side drawer component for Quick-Verify proof replay visualization.
|
||||||
|
- Stream step-by-step verification progress with collapsible receipt viewer.
|
||||||
|
- Handle failure states with "Why?" explainer and log excerpt.
|
||||||
|
- Working directory: `src/Web/StellaOps.Web/src/app/shared/components/quick-verify-drawer/`
|
||||||
|
- Expected evidence: Unit tests, Storybook stories, E2E test for drawer flow.
|
||||||
|
|
||||||
|
## Dependencies & Concurrency
|
||||||
|
- Depends on: Evidence Ribbon emitting `quickVerifyClick` (SPRINT_20260125_001 ER-004).
|
||||||
|
- Reuses: `replay-progress.component.ts`, `replay.service.ts` for actual replay logic.
|
||||||
|
- Can develop drawer shell in parallel with Evidence Ribbon work.
|
||||||
|
|
||||||
|
## Documentation Prerequisites
|
||||||
|
- Advisory wireframe spec (drawer behavior section).
|
||||||
|
- Existing components:
|
||||||
|
- `src/Web/StellaOps.Web/src/app/shared/components/reproduce/replay-progress.component.ts`
|
||||||
|
- `src/Web/StellaOps.Web/src/app/shared/components/reproduce/replay-result.component.ts`
|
||||||
|
- `src/Web/StellaOps.Web/src/app/shared/components/evidence-drawer/evidence-drawer.component.ts`

| 2026-01-25 | All acceptance criteria verified. Sprint archived. | Claude |
|
||||||
|
|
||||||
|
## Decisions & Risks
|
||||||
|
- **Decision:** Reuse existing `replay.service.ts` rather than create new verification service.
|
||||||
|
- **Decision:** Use Angular CDK overlay for drawer (consistent with existing drawers).
|
||||||
|
- **Risk:** SSE connection may not be supported by all backends. Mitigation: Fall back to polling.
|
||||||
|
- **Risk:** Large receipt JSON may cause performance issues. Mitigation: Virtual scroll for arrays > 100 items.
|
||||||
|
|
||||||
|
## Next Checkpoints
|
||||||
|
- Drawer shell demo with mock steps.
|
||||||
|
- Full integration demo with Evidence Ribbon.
|
||||||
|
- E2E test passing for complete flow.

## Decisions & Risks
|
||||||
|
- **Decision**: Use Polly-style circuit breaker pattern (well-understood, testable)
|
||||||
|
- **Decision**: Mirror failover is opt-in (organizations may not have mirrors)
|
||||||
|
- **Decision**: Per-backend circuit breakers for isolation
|
||||||
|
- **Risk**: Conformance tests require frozen fixtures; ensure fixtures remain valid - MITIGATED: Created deterministic JSON fixtures
|
||||||
|
- **Risk**: Circuit breaker timing is environment-dependent; make thresholds configurable - MITIGATED: All thresholds configurable via RekorCircuitBreakerOptions
|
||||||
|
|
||||||

# Sprint 20260125_003 - Quiet Triage Lane (MVP)
|
||||||
|
|
||||||
|
## Topic & Scope
|
||||||
|
- Add explicit "Quiet Triage" lane for parking low-confidence/weak findings with auto-prune TTL.
|
||||||
|
- Resolve terminology conflict: current "quiet" = actionable; advisory "Quiet Triage" = parked items.
|
||||||
|
- Implement TTL countdown chip, auto-prune UI, Recheck/Promote inline actions.
|
||||||
|
- Working directory: `src/Web/StellaOps.Web/src/app/features/triage/`
|
||||||
|
- Expected evidence: Unit tests, Storybook stories, E2E test for lane transitions.
|
||||||
|
|
||||||
|
## Dependencies & Concurrency
|
||||||
|
- No upstream dependencies.
|
||||||
|
- Can run in parallel with SPRINT_20260125_001 (Evidence Ribbon).
|
||||||
|
- Backend may need `POST /triage/move` and `GET /triage/parked` endpoints.
|
||||||
|
|
||||||
|
## Documentation Prerequisites
|
||||||
|
- Advisory wireframe spec (Quiet Triage lane section).
|
||||||
|
- Existing components:
|
||||||
|
- `src/Web/StellaOps.Web/src/app/features/triage/components/triage-lane-toggle/triage-lane-toggle.component.ts`

## Decisions & Risks
|
||||||
|
- **Decision:** Rename "quiet" to "active" to resolve terminology conflict with advisory.
|
||||||
|
- **Decision:** Default TTL is 30 days per advisory spec; configurable per-tenant in future.
|
||||||
|
- **Risk:** Backend may not have `/triage/parked` endpoint. Mitigation: Verify with backend team; may need backend sprint.
|
||||||
|
- **Risk:** Auto-prune logic lives server-side; UI only displays countdown. Mitigation: Document that server handles actual deletion.
|
||||||
|
|
||||||
|
## Next Checkpoints
|
||||||
|
- Three-lane toggle demo with counts.
|
||||||
|
- Parked lane with mock items and TTL chips.
|
||||||
|
- Full integration with lane move API.

# Sprint 20260125_004 - VEX Merge Panel Enhancement (v1)
|
||||||
|
|
||||||
|
## Topic & Scope
|
||||||
|
- Enhance existing VEX conflict resolution UI with 3-column layout per advisory spec.
|
||||||
|
- Add inline merge diff badges, provenance popover with raw VEX, "Open in Trust Algebra" link.
|
||||||
|
- Working directory: `src/Web/StellaOps.Web/src/app/features/vex-studio/`
|
||||||
|
- Expected evidence: Unit tests, Storybook stories, visual comparison with advisory wireframe.
|
||||||
|
|
||||||
|
## Dependencies & Concurrency
|
||||||
|
- No strict upstream dependencies; builds on existing `vex-conflict-studio.component.ts`.
|
||||||
|
- Can run in parallel with MVP sprints.
|
||||||
|
- "Open in Trust Algebra" requires policy module routing to exist.
|
||||||
|
|
||||||
|
## Documentation Prerequisites
|
||||||
|
- Advisory wireframe spec (VEX Merge panel section).
|
||||||
|
- Existing components:
|
||||||
|
- `src/Web/StellaOps.Web/src/app/features/vex-studio/vex-conflict-studio.component.ts`
|
||||||
|
- `src/Web/StellaOps.Web/src/app/features/vex-studio/components/vex-merge-explanation/vex-merge-explanation.component.ts`
|
||||||
|
- `src/Web/StellaOps.Web/src/app/features/snapshot/components/merge-preview/merge-preview.component.ts`

## Decisions & Risks
|
||||||
|
- **Decision:** Enhance existing components rather than rebuild; minimize breaking changes.
|
||||||
|
- **Decision:** Trust Algebra route assumed to exist; if not, link disabled with tooltip.
|
||||||
|
- **Risk:** Raw VEX snippet may be large. Mitigation: Truncate with "Show full" expand.
|
||||||
|
- **Risk:** Provenance data may not be returned by current API. Mitigation: Verify `/vex/conflicts/{id}/provenance` endpoint exists.
|
||||||
|
|
||||||
|
## Next Checkpoints
|
||||||
|
- 3-column layout demo with mock data.
|
||||||
|
- Provenance popover with real VEX snippets.
|
||||||
|
- Integration with Trust Algebra navigation.

## Decisions & Risks
|
||||||
|
- **Decision:** StellaBundle is a preset of existing export, not a new export type.
|
||||||
|
- **Decision:** OCI format is default for StellaBundle; allow override for air-gap scenarios (tar.gz).
|
||||||
|
- **Risk:** Backend may not support `replay_log.json` in export. Mitigation: Coordinate with backend team; may need API update.
|
||||||
|
- **Risk:** OCI push may fail in restricted environments. Mitigation: Show helpful error with alternative (download tar.gz).
|
||||||
|
|
||||||
|
## Next Checkpoints
|
||||||
|
- Button component demo with mock export.
|
||||||
|
- Full export flow with OCI reference toast.
|
||||||
|
- Integration test: export → verify contents → copy reference.

# Sprint 20260125_006 - A/B Deploy Diff Panel (v2)
|
||||||
|
|
||||||
|
## Topic & Scope
|
||||||
|
- Build new SBOM side-by-side diff panel for comparing two deployment versions.
|
||||||
|
- Show Added/Removed/Changed components with policy hit annotations.
|
||||||
|
- Implement Block/Allow/Schedule canary one-click actions with override flow.
|
||||||
|
- Working directory: `src/Web/StellaOps.Web/src/app/features/deploy-diff/`
|
||||||
|
- Expected evidence: Unit tests, Storybook stories, E2E test for diff + action flow.
|
||||||
|
|
||||||
|
## Dependencies & Concurrency
|
||||||
|
- No strict upstream dependencies; new feature module.
|
||||||
|
- Benefits from MVP completion (Evidence Ribbon for policy hit annotations).
|
||||||
|
- Backend needs `GET /sbom/diff` endpoint.
|
||||||
|
|
||||||
|
## Documentation Prerequisites
|
||||||
|
- Advisory wireframe spec (A/B Deploy Diff panel section).
|
||||||
|
- Related existing components:
|
||||||
|
- `src/Web/StellaOps.Web/src/app/shared/components/diff-viewer/diff-viewer.component.ts`
|
||||||
|
- `src/Web/StellaOps.Web/src/app/features/sbom/` (existing SBOM components)
|
||||||
|

|
| 2026-01-25 | Sprint created from advisory gap analysis | Planning |
|
||||||
|
| 2026-01-25 | Implemented DD-001 through DD-010: Complete deploy-diff feature module with models, service, all components (sbom-side-by-side, component-diff-row, policy-hit-annotation, deploy-action-bar, override-dialog, deploy-diff-panel), routes, page, and unit tests | Claude |

| 2026-01-25 | All acceptance criteria verified. Sprint archived. | Claude |
|
||||||
|
|
||||||
|
## Decisions & Risks
|
||||||
|
- **Decision:** Virtual scroll required for large SBOMs; defer to component library choice (CDK virtual scroll).
|
||||||
|
- **Decision:** Override audit stored server-side; UI only captures input and shows preview.
|
||||||
|
- **Decision:** Used Angular signals for reactive state management.
|
||||||
|
- **Risk:** `GET /sbom/diff` endpoint may not exist. Mitigation: Verify with backend; may need backend sprint.
|
||||||
|
- **Risk:** Large diffs (1000+ components) may cause performance issues. Mitigation: Implement pagination or progressive loading.
|
||||||
|
- **Risk:** Side-by-side alignment complex for mismatched components. Mitigation: Use placeholder rows for alignment.
|
||||||
|
|
||||||
|
## Next Checkpoints
|
||||||
|
- Module scaffolding complete.
|
||||||
|
- Side-by-side viewer demo with mock data.
|
||||||
|
- Full flow demo with policy override.
|
||||||
|
- E2E test in CI.

# Additional Community Plugin Grant - StellaOps Addendum to BUSL-1.1
|
||||||
|
|
||||||
|
**Archived:** 2026-01-25
|
||||||
|
**Status:** Implemented
|
||||||
|
**Sprint:** SPRINT_20260125_001_DOCS_community_plugin_grant_addendum

|
||||||
|
## Original Advisory
|
||||||
|
|
||||||
|
Here's a ready-to-ship "Additional Use Grant" addendum you can attach to BUSL-1.1 to open a free community plugin tier while still blocking SaaS copycats.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
# Additional Community Plugin Grant - StellaOps Addendum to BUSL-1.1
|
||||||
|
|
||||||
|
1. **Definitions.** For purposes of this Addendum: (a) "**Plugin**" means a separately packaged extension written to interface with the Licensed Work using documented public plugin APIs or integration points published by Licensor; (b) "**Environment**" means an instance of the Licensed Work under the control of a single legal entity (customer/organization) and deployed to a unique production orchestration boundary (example: a distinct on-prem cluster, a private cloud tenant, or a named cloud account); (c) "**Scan**" means one completed execution of the Licensed Work's vulnerability or artifact analysis pipeline that produces a report or SBOM/VEX output and is billed or metered as a single unit by Licensor's published metrics.
|
||||||
|
|
||||||
|
2. **Community Plugin Grant.** Notwithstanding anything to the contrary in BUSL-1.1, Licensor hereby grants each Recipient a worldwide, non-exclusive, royalty-free license to: (i) use, run, and reproduce a Plugin in production solely for the Recipient's internal business operations in up to **three (3) Environments**; and (ii) perform up to **nine hundred and ninety-nine (999) Scans per calendar day** across all such Environments. This grant extends to modification and redistribution of the Plugin under the same terms, provided redistribution is not packaged with a commercial managed hosting offering in breach of Section 4 below.
|
||||||
|
|
||||||
|
3. **Distribution & Attribution.** Recipients may distribute Plugin source or binaries under the same license terms as the Licensed Work (including this Addendum). Distributed copies must retain a conspicuous attribution to Licensor and include this Addendum verbatim. Redistribution that embeds or repackages Licensor's core runtime binaries into a commercial product that functions as a competing managed service requires a separate commercial license from Licensor.
|
||||||
|
|
||||||
|
4. **SaaS / Managed Offering Restriction.** Recipients are **not** permitted to offer the Licensed Work or a Plugin (or a service that substantially replicates the Licensed Work's core features) as a commercial hosted service, SaaS, or managed/white-label hosting offering to third parties without a separate written commercial license from Licensor. This restriction applies whether the service is offered directly, via a reseller, or embedded into a larger multi-tenant managed platform. **Limited exceptions:** an organization may host the Licensed Work internally for its own customers (e.g., an MSP hosting distinct single-tenant instances per customer) only if each hosted instance is covered by the organization's commercial license or if the hosted instance remains fully isolated and used exclusively by the licensee's employees and affiliates; public multi-tenant paid hosting that provides the Licensed Work's functionality to unrelated third parties is prohibited under this Addendum absent commercial licensing.
|
||||||
|
|
||||||
|
5. **Enforcement & Telemetry.** Licensor may reasonably audit or require self-reporting to verify compliance with the Environment and Scan limits; Licensor may provide an optional, privacy-respecting metering endpoint for voluntary telemetry; any audit shall be subject to standard confidentiality and data-protection safeguards.
|
||||||
|
|
||||||
|
6. **Term & Upgrade.** This Addendum applies to releases of the Licensed Work that include it; Licensor may amend the numeric limits (Environments / Scans) by publishing a new Addendum version; such changes do not retroactively affect prior distributions.
|
||||||
|
|
||||||
|
7. **No waiver of other BUSL rights.** Except as explicitly modified by this Addendum, all terms of BUSL-1.1 remain in full force and effect.
|
||||||
|
|
||||||
|
8. **Legal & Compliance Notice.** This Addendum is intended as a narrow community grant to encourage plugin ecosystems while protecting Licensor's commercial SaaS market; it is not legal advice and should be reviewed by counsel prior to publication.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Why this fits BUSL-1.1 (and how it compares)
|
||||||
|
|
||||||
|
* BUSL-1.1 explicitly allows "**Additional Use Grants**" to carve out limited production rights; your addendum uses that exact mechanism. ([spdx.org][1])
|
||||||
|
* The **SaaS/managed-service limitation** mirrors how other source-available models protect against hosted competitors (e.g., Confluent Community License "Excluded Purpose," Elastic ELv2 limits, SSPL's service operator obligations-different legal mechanics, same goal of restricting hosted competition). ([Confluent][2])
|
||||||
|
|
||||||
|
## Mini change log (what changed vs BUSL and why)
|
||||||
|
|
||||||
|
* Added an explicit **community plugin grant** with **3 Environments / 999 Scans/day** to allow bounded production usage without a commercial license. (Maps to BUSL's Additional Use Grant.) ([spdx.org][1])
|
||||||
|
* Clarified **distribution channels** for plugins and attribution retention; barred **repackaging into competing managed services** (a narrower prohibition akin to Confluent/Elastic patterns). ([Confluent][3])
|
||||||
|
* Made **SaaS prohibition** explicit, using a permission-based restriction (not SSPL-style copyleft requirements). ([MongoDB][4])
|
||||||
|
|
||||||
|
## EU competition & privacy flags (quick)
|
||||||
|
|
||||||
|
* **Competition:** Numeric caps + SaaS carve-out can face scrutiny if you hold market power; get EU/EEA competition counsel to review positioning and reseller language. (Background on recent license shifts and scrutiny.) ([DataCenterKnowledge][5])
|
||||||
|
* **Privacy/GDPR:** Keep telemetry strictly **opt-in**, data-minimized, and backed by a DPA; avoid collecting customer content during audits. (General best-practice.) ([Elastic][6])
|
||||||
|
|
||||||
|
## Practical next steps
|
||||||
|
|
||||||
|
1. Publish this as **"Appendix A - Community Plugin Grant"** in your repo next to BUSL-1.1; 2) add a short **FAQ** (what counts as a Plugin, how to count Environments/Scans, examples of a managed-service breach); 3) provide a simple **self-attestation** form and optional metering endpoint to help users stay inside the limits. (HashiCorp's BUSL pages/FAQ are a good model for clear interpretive guidance.) ([HashiCorp | An IBM Company][7])
|
||||||
|
|
||||||
|
If you want, I can also tailor a 1-page FAQ and a compliance attestation template to drop into `LICENSES/` and your website.

- `docs/legal/SAAS_MSP_GUIDANCE.md` - SaaS/MSP guidance
|
||||||
|
- `docs/legal/ENFORCEMENT_TELEMETRY_POLICY.md` - Enforcement policy
|
||||||
|
- `docs/legal/COMPLIANCE_ATTESTATION_FORM.md` - Attestation process
|
||||||
|
- `docs/legal/templates/self-attestation-form.md` - Fillable template
|
||||||
|
|
||||||
|
### Documents Updated
|
||||||
|
- `LICENSE` - Added Section 5 referencing addendum
|
||||||
|
- `NOTICE.md` - Added plugin attribution section
|
||||||
|
- `docs/legal/README.md` - Added all new document links
|
||||||
|
- `docs/legal/LEGAL_FAQ_QUOTA.md` - Added cross-references
|
||||||
|
- `docs/legal/LICENSE-COMPATIBILITY.md` - Added plugin distribution section
|
||||||
|
|
||||||
|
### Key Decisions
|
||||||
|
1. Created addendum as separate file (not embedded in LICENSE) for independent versioning
|
||||||
|
2. Created comprehensive FAQ rather than minimal one
|
||||||
|
3. Created templates directory for fillable forms
|
||||||
|
|
||||||
|
### Deferred Items
|
||||||
|
- CI workflow updates for addendum validation
|
||||||
|
- Plugin development documentation (separate from legal docs)
|
||||||
|
- Legal counsel review (external dependency)

# Compliance Attestation Form
|
||||||
|
|
||||||
|
**Document Version:** 1.0.0
|
||||||
|
**Last Updated:** 2026-01-25
|
||||||
|
|
||||||
|
This document describes the compliance attestation process for Stella Ops Community
|
||||||
|
Plugin Grant users. For a fillable template, see `templates/self-attestation-form.md`.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. Purpose
|
||||||
|
|
||||||
|
The compliance attestation process allows organizations to demonstrate compliance
|
||||||
|
with the Stella Ops Community Plugin Grant without enabling telemetry or undergoing
|
||||||
|
formal audit. It provides a trust-based mechanism for license compliance verification.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. Who Should Attest
|
||||||
|
|
||||||
|
Annual attestation is recommended for:
|
||||||
|
|
||||||
|
- Organizations using Stella Ops in production
|
||||||
|
- Deployments approaching free tier limits (2+ environments, 500+ scans/day)
|
||||||
|
- Organizations with data governance policies prohibiting telemetry
|
||||||
|
- MSPs managing customer deployments
|
||||||
|
|
||||||
|
Attestation is **not required** for:
|
||||||
|
- Non-production or evaluation use
|
||||||
|
- Single-environment deployments well within limits
|
||||||
|
- Organizations with active telemetry enabled
|
||||||
|
|
||||||

## 8. Frequently Asked Questions
|
||||||
|
|
||||||
|
### Q: Is attestation mandatory?
|
||||||
|
|
||||||
|
**A:** No. Attestation is voluntary and recommended. It provides documented evidence
|
||||||
|
of compliance in case of future questions.
|
||||||
|
|
||||||
|
### Q: What if our usage changes after attesting?
|
||||||
|
|
||||||
|
**A:** Submit an updated attestation within 30 days of material changes. Good-faith
|
||||||
|
updates are appreciated and do not trigger penalties.
|
||||||
|
|
||||||
|
### Q: Can we attest for multiple installations?
|
||||||
|
|
||||||
|
**A:** Yes. Use one form per installation, or contact compliance@stella-ops.org for
|
||||||
|
a consolidated form for large deployments.
|
||||||
|
|
||||||
|
### Q: What happens if we can't attest to compliance?
|
||||||
|
|
||||||
|
**A:** Contact sales@stella-ops.org to discuss commercial licensing options. There's
|
||||||
|
no penalty for recognizing a need to upgrade.
|
||||||
|
|
||||||
|
### Q: Is the attestation legally binding?
|
||||||
|
|
||||||
|
**A:** The attestation is a representation of fact. Knowingly false attestation may
|
||||||
|
result in license termination. However, good-faith errors with prompt correction
|
||||||
|
are not penalized.

|
||||||
|
|
||||||
|
## 2. Audit Rights
|
||||||
|
|
||||||
|
### 2.1 When Audits May Occur
|
||||||
|
|
||||||
|
stella-ops.org reserves the right to request compliance verification:
|
||||||
|
|
||||||
|
- **Frequency:** No more than once per calendar year per licensee
|
||||||
|
- **Notice:** Minimum 30 days written notice
|
||||||
|
- **Scope:** Limited to verification of Environment count and Scan volume
|
||||||
|
- **Trigger:** Audits may be initiated based on:
|
||||||
|
- Routine sampling of licensees
|
||||||
|
- Credible reports of non-compliance
|
||||||
|
- Self-reported concerns from licensees
|
||||||
|
|
||||||
|
### 2.2 Audit Process
|
||||||
|
|
||||||
|
**Step 1: Notice**
|
||||||
|
- Written notice via email to registered contact
|
||||||
|
- Specifies audit scope and requested documentation
|
||||||
|
- Provides minimum 30-day response window
|
||||||
|
|
||||||
|
**Step 2: Documentation Request**
|
||||||
|
- Licensee provides requested information:
|
||||||
|
- Number of active Environments
|
||||||
|
- Scan volume metrics (e.g., from Stella Ops admin dashboard)
|
||||||
|
- Deployment architecture summary
|
||||||
|
- No access to scan content, vulnerabilities, or business data required
|
||||||
|
|
||||||
|
**Step 3: Review**
|
||||||
|
- stella-ops.org reviews submitted documentation
|
||||||
|
- May request clarification on ambiguous items
|
||||||
|
- Typically completed within 15 business days
|
||||||
|
|
||||||
|
**Step 4: Resolution**
|
||||||
|
- Compliant: Written confirmation provided
|
||||||
|
- Minor variance: Grace period to remediate
|
||||||
|
- Significant non-compliance: Commercial license discussion
|
||||||
|
|
||||||
|
### 2.3 Audit Safeguards
|
||||||
|
|
||||||
|
All audits are conducted with:
|
||||||
|
|
||||||
|
- **Confidentiality:** All submitted information treated as confidential business
|
||||||
|
information under mutual NDA
|
||||||
|
- **Data protection:** GDPR-compliant handling of any personal data
|
||||||
|
- **Limited retention:** Audit documentation retained for maximum 3 years
|
||||||
|
- **No content access:** We never request access to scan results, source code,
|
||||||
|
or customer business data
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 3. Voluntary Telemetry
|
||||||
|
|
||||||
|
### 3.1 Telemetry Overview
|
||||||
|
|
||||||
|
Stella Ops provides an **optional** telemetry endpoint for users who wish to
|
||||||
|
automate compliance reporting.
|
||||||
|
|
||||||
|
**Key principles:**
|
||||||
|
- **Strictly opt-in:** Disabled by default
|
||||||
|
- **Aggregate metrics only:** No detailed scan data
|
||||||
|
- **Privacy-respecting:** No PII or customer content
|
||||||
|
- **User-controlled:** Can be disabled at any time
|
||||||
|
|
||||||
|
### 3.2 What Telemetry Collects (When Enabled)
|
||||||
|
|
||||||
|
| Metric | Description | Purpose |
|
||||||
|
|--------|-------------|---------|
|
||||||
|
| `installation_id` | Anonymous installation identifier | Deduplicate reports |
|
||||||
|
| `environment_count` | Number of active environments | License compliance |
|
||||||
|
| `scan_count_24h` | Scans in rolling 24-hour period | License compliance |
|
||||||
|
| `version` | Stella Ops version | Compatibility/support |
|
||||||
|
| `timestamp` | Report timestamp | Time-series analysis |
|
||||||
|
|
||||||
|
### 3.3 What Telemetry Does NOT Collect
|
||||||
|
|
||||||
|
- Scan results or vulnerability data
|
||||||
|
- Customer names or identifiers
|
||||||
|
- IP addresses (beyond transport layer)
|
||||||
|
- Source code or artifact contents
|
||||||
|
- User credentials or tokens
|
||||||
|
- Business-sensitive configuration
|
||||||
|
|
||||||
|
### 3.4 Enabling/Disabling Telemetry
|
||||||
|
|
||||||
|
**To enable:**
|
||||||
|
```yaml
|
||||||
|
# In stella-ops.yaml
|
||||||
|
telemetry:
|
||||||
|
enabled: true
|
||||||
|
endpoint: https://telemetry.stella-ops.org/v1/report
|
||||||
|
```
|
||||||
|
|
||||||
|
**To disable (default):**
|
||||||
|
```yaml
|
||||||
|
telemetry:
|
||||||
|
enabled: false
|
||||||
|
```
|
||||||
|
|
||||||
|
**Environment variable override:**
|
||||||
|
```bash
|
||||||
|
STELLAOPS_TELEMETRY_ENABLED=false
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.5 Telemetry Data Handling
|
||||||
|
|
||||||
|
- **Transmission:** TLS 1.3 encrypted
|
||||||
|
- **Storage:** Aggregated and anonymized within 24 hours
|
||||||
|
- **Retention:** Raw reports retained for maximum 90 days
|
||||||
|
- **Access:** Limited to license compliance team
|
||||||
|
- **No sale:** Never sold or shared with third parties
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. Self-Attestation
|
||||||
|
|
||||||
|
### 4.1 Overview
|
||||||
|
|
||||||
|
As an alternative to telemetry, licensees may provide annual self-attestation
|
||||||
|
of compliance. This is the recommended approach for organizations with strict
|
||||||
|
data governance requirements.
|
||||||
|
|
||||||
|
### 4.2 Attestation Process
|
||||||
|
|
||||||
|
1. **Download form:** `docs/legal/templates/self-attestation-form.md`
|
||||||
|
2. **Complete attestation:** Fill in required fields
|
||||||
|
3. **Submit:** Email to compliance@stella-ops.org
|
||||||
|
4. **Confirmation:** Receive acknowledgment within 10 business days
|
||||||
|
|
||||||
|
### 4.3 Attestation Frequency
|
||||||
|
|
||||||
|
- **Annual:** Submit once per calendar year
|
||||||
|
- **Upon request:** May be requested as part of audit
|
||||||
|
- **Voluntary updates:** Submit anytime if circumstances change
|
||||||
|
|
||||||
|
### 4.4 False Attestation
|
||||||
|
|
||||||
|
Knowingly providing false attestation information may result in:
|
||||||
|
- Immediate termination of license rights
|
||||||
|
- Requirement to obtain commercial license
|
||||||
|
- Potential legal action for license violation

## 5. Compliance Verification Methods
|
||||||
|
|
||||||
|
### 5.1 Recommended: Built-in Dashboard
|
||||||
|
|
||||||
|
Stella Ops includes a compliance dashboard at `/admin/compliance`:
|
||||||
|
|
||||||
|
```
|
||||||
|
Compliance Status
|
||||||
|
─────────────────
|
||||||
|
License Type: Community (Free Tier)
|
||||||
|
Environments: 2 of 3 (within limit)
|
||||||
|
Scans (24h): 456 of 999 (within limit)
|
||||||
|
Status: COMPLIANT
|
||||||
|
```
|
||||||
|
|
||||||
|
This dashboard can be used to:
|
||||||
|
- Monitor current usage against limits
|
||||||
|
- Generate compliance reports for audit
|
||||||
|
- Export metrics for self-attestation
|
||||||
|
|
||||||
|
### 5.2 API-Based Verification
|
||||||
|
|
||||||
|
Compliance metrics are available via API:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
curl -H "Authorization: Bearer $ADMIN_TOKEN" \
|
||||||
|
https://your-instance/api/v1/admin/compliance/metrics
|
||||||
|
```
|
||||||
|
|
||||||
|
Response:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"environment_count": 2,
|
||||||
|
"environment_limit": 3,
|
||||||
|
"scan_count_24h": 456,
|
||||||
|
"scan_limit_24h": 999,
|
||||||
|
"compliant": true,
|
||||||
|
"timestamp": "2026-01-25T14:30:00Z"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 5.3 Log-Based Verification
|
||||||
|
|
||||||
|
For organizations that prefer log analysis:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Extract compliance metrics from logs
|
||||||
|
grep "compliance_check" /var/log/stellaops/audit.log | tail -1
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 6. Remediation
|
||||||
|
|
||||||
|
### 6.1 Exceeding Limits
|
||||||
|
|
||||||
|
If you discover you've exceeded free tier limits:
|
||||||
|
|
||||||
|
1. **Immediate:** Usage may be throttled (see `30_QUOTA_ENFORCEMENT_FLOW1.md`)
|
||||||
|
2. **Short-term:** Reduce environments or scan volume to return to compliance
|
||||||
|
3. **Long-term:** Obtain commercial license for ongoing needs
|
||||||
|
|
||||||
|
### 6.2 Grace Period
|
||||||
|
|
||||||
|
For good-faith limit exceedances:
|
||||||
|
- **First occurrence:** 30-day grace period to remediate
|
||||||
|
- **Repeated occurrence:** 15-day grace period
|
||||||
|
- **Intentional abuse:** No grace period; commercial license required immediately
|
||||||
|
|
||||||
|
### 6.3 Commercial License Transition
|
||||||
|
|
||||||
|
If you need to exceed free tier limits:
|
||||||
|
- Contact sales@stella-ops.org
|
||||||
|
- Licenses can be backdated to cover grace period
|
||||||
|
- No penalty for good-faith users who remediate promptly
|
||||||

## General Questions
|
||||||
|
|
||||||
|
### Q1: What constitutes a "Plugin" under the Community Plugin Grant?
|
||||||
|
|
||||||
|
**A:** A Plugin is a separately packaged extension that interfaces with Stella Ops using
|
||||||
|
documented public plugin APIs or integration points. This includes:
|
||||||
|
|
||||||
|
**Examples of Plugins:**
|
||||||
|
- Custom vulnerability connectors (e.g., integrating a proprietary vulnerability database)
|
||||||
|
- CI/CD integrations (e.g., Jenkins, GitLab CI, Azure DevOps plugins)
|
||||||
|
- Output formatters (e.g., custom report templates, dashboard integrations)
|
||||||
|
- Notification connectors (e.g., Slack, Teams, PagerDuty integrations)
|
||||||
|
- Scanner analyzers (e.g., language-specific dependency parsers)
|
||||||
|
- Policy gates (e.g., custom compliance rules)
|
||||||
|
|
||||||
|
**NOT Plugins (derivative works requiring BUSL-1.1 compliance):**
|
||||||
|
- Modifications to Stella Ops core source code
|
||||||
|
- Forks that include modified Stella Ops components
|
||||||
|
- Extensions that copy substantial portions of Stella Ops internals
|
||||||
|
|
||||||
|
### Q2: Can I sell my plugin commercially?
|
||||||
|
|
||||||
|
**A:** Yes. You may develop and sell plugins commercially under license terms of your
|
||||||
|
choosing (including proprietary terms), provided:
|
||||||
|
|
||||||
|
1. Your plugin does not include, copy, or modify Stella Ops source code; AND
|
||||||
|
2. You comply with the attribution requirements (see Q4).
|
||||||
|
|
||||||
|
Your commercial plugin license is entirely separate from the BUSL-1.1 license covering
|
||||||
|
Stella Ops itself.
|
||||||
|
|
||||||
|
### Q3: Do I need to open-source my plugin?
|
||||||
|
|
||||||
|
**A:** No. Plugins that interface with Stella Ops through public APIs do not need to be
|
||||||
|
open-sourced. You may use any license you choose, including proprietary licenses.
|
||||||
|
|
||||||
|
**Exception:** If your plugin includes, copies, or modifies any portion of Stella Ops
|
||||||
|
source code, it becomes a derivative work subject to BUSL-1.1.
|
||||||
|
|
||||||
|
### Q4: What attribution is required when distributing a plugin?
|
||||||
|
|
||||||
|
**A:** When distributing a plugin, you should:
|
||||||
|
|
||||||
|
1. **Acknowledge compatibility:** State that your plugin is designed for use with
|
||||||
|
Stella Ops (e.g., "Compatible with Stella Ops Suite")
|
||||||
|
|
||||||
|
2. **Include license reference:** If your plugin distribution includes any Stella Ops
|
||||||
|
components (even configuration samples), include the LICENSE and NOTICE files
|
||||||
|
|
||||||
|
3. **Link to source:** Provide a link to the Stella Ops source repository
|
||||||
|
(https://git.stella-ops.org)
|
||||||
|
|
||||||
|
**Minimum attribution example:**
|
||||||
|
```
|
||||||
|
This plugin is designed for use with Stella Ops Suite.
|
||||||
|
Stella Ops is licensed under BUSL-1.1. See https://git.stella-ops.org
|
||||||
|
```

||||||

## Usage Limits
|
||||||
|
|
||||||
|
### Q5: What counts as an "Environment"?
|
||||||
|
|
||||||
|
**A:** An Environment is a logically separated workspace within a Stella Ops installation.
|
||||||
|
The free tier allows up to 3 Environments per installation.
|
||||||
|
|
||||||
|
**Each of these counts as one Environment:**
|
||||||
|
- A "Development" environment for testing scans
|
||||||
|
- A "Staging" environment for pre-production validation
|
||||||
|
- A "Production" environment for live deployments
|
||||||
|
- A tenant/workspace in a multi-tenant setup
|
||||||
|
- A project or team workspace with isolated configuration
|
||||||
|
|
||||||
|
**These do NOT count as separate Environments:**
|
||||||
|
- High-availability replicas of the same environment
|
||||||
|
- Read replicas or cache nodes
|
||||||
|
- Backup/disaster recovery instances (if not actively used)
|
||||||
|
|
||||||
|
**Example scenarios:**
|
||||||
|
|
||||||
|
| Scenario | Environment Count |
|
||||||
|
|----------|------------------|
|
||||||
|
| Single dev laptop installation | 1 |
|
||||||
|
| Dev + Staging + Prod for one team | 3 |
|
||||||
|
| Two separate teams, each with Dev + Prod | 4 (requires commercial license) |
|
||||||
|
| MSP hosting 5 isolated customer instances | 5 (requires commercial license) |
|
||||||
|
|
||||||
|
### Q6: What counts as a "Scan"?
|
||||||
|
|
||||||
|
**A:** A Scan is one completed execution of Stella Ops' vulnerability or artifact analysis
|
||||||
|
pipeline that produces a new result. The free tier allows up to 999 Scans per calendar day.
|
||||||
|
|
||||||
|
**Counts as a Scan:**
|
||||||
|
- First-time scan of a container image (new hash)
|
||||||
|
- Re-scan of a modified image (hash changed)
|
||||||
|
- SBOM generation for a new artifact
|
||||||
|
- VEX statement generation for new findings
|
||||||
|
|
||||||
|
**Does NOT count as a Scan:**
|
||||||
|
- Cache hits (retrieving previously scanned results)
|
||||||
|
- Viewing existing scan reports
|
||||||
|
- Policy evaluation on cached data
|
||||||
|
- API queries for existing results
|
||||||
|
|
||||||
|
**Deduplication:** Stella Ops uses hash-based deduplication. Scanning the same artifact
|
||||||
|
multiple times only counts as one Scan if the hash hasn't changed.
|
||||||
|
|
||||||
|
### Q7: What happens if my users exceed the free limits?
|
||||||
|
|
||||||
|
**A:** If users of your plugin exceed the free tier limits (3 Environments or 999 Scans/day):
|
||||||
|
|
||||||
|
1. **They need a commercial license** - The user (not the plugin developer) is responsible
|
||||||
|
for licensing compliance
|
||||||
|
2. **Your plugin continues to work** - There's no technical enforcement in the plugin itself
|
||||||
|
3. **Quota enforcement is server-side** - Stella Ops may introduce delays after limits
|
||||||
|
are exceeded (see `docs/legal/30_QUOTA_ENFORCEMENT_FLOW1.md`)
|
||||||
|
|
||||||
|
As a plugin developer, you should:
|
||||||
|
- Document the free tier limits in your plugin documentation
|
||||||
|
- Recommend users contact stella-ops.org for commercial licensing if they exceed limits
|
||||||
|
- Not build quota circumvention into your plugin
|
||||||
|
|

## Bundling & Distribution
|
||||||
|
|
||||||
|
### Q8: Can I bundle Stella Ops core with my plugin?
|
||||||
|
|
||||||
|
**A:** This depends on how you bundle:
|
||||||
|
|
||||||
|
**Allowed (aggregation):**
|
||||||
|
- Shipping your plugin alongside Stella Ops as separate components
|
||||||
|
- Docker Compose files that reference Stella Ops images
|
||||||
|
- Helm charts that deploy Stella Ops as a dependency
|
||||||
|
- Installation scripts that download Stella Ops separately
|
||||||
|
|
||||||
|
**Requires BUSL-1.1 compliance (derivative work):**
|
||||||
|
- Embedding Stella Ops source code into your plugin
|
||||||
|
- Modifying Stella Ops binaries and redistributing
|
||||||
|
- Creating a single binary that includes Stella Ops components
|
||||||
|
|
||||||
|
**Requires commercial license:**
|
||||||
|
- Bundling into a competing managed service offering
|
||||||
|
- White-labeling Stella Ops functionality
|
||||||
|
|
||||||
|
### Q9: Can I create a plugin that modifies Stella Ops behavior at runtime?
|
||||||
|
|
||||||
|
**A:** Yes, if the modification uses documented extension points:
|
||||||
|
|
||||||
|
**Allowed:**
|
||||||
|
- Plugins that register custom handlers via plugin APIs
|
||||||
|
- Extensions that add new endpoints or processing steps
|
||||||
|
- Integrations that intercept and transform data via documented hooks
|
||||||
|
|
||||||
|
**Not allowed without BUSL-1.1 derivative work compliance:**
|
||||||
|
- Runtime patching of Stella Ops binaries
|
||||||
|
- Monkey-patching internal classes or methods
|
||||||
|
- Replacing core components at runtime
|
||||||
|
|
||||||
|
The key distinction is whether you're using **documented public APIs** (allowed) vs.
|
||||||
|
**undocumented internal behavior** (derivative work).

|
||||||
|
## Commercial Considerations
|
||||||
|
|
||||||
|
### Q10: Can my plugin be used with Stella Ops commercial/SaaS offerings?
|
||||||
|
|
||||||
|
**A:** Yes. Plugins designed for the Community Plugin Grant are compatible with commercial
|
||||||
|
Stella Ops deployments. Commercial customers may use community plugins subject to their
|
||||||
|
commercial license terms.
|
||||||
|
|
||||||
|
### Q11: Do I need Licensor approval to publish a plugin?
|
||||||
|
|
||||||
|
**A:** No. You do not need approval from stella-ops.org to:
|
||||||
|
- Develop plugins
|
||||||
|
- Publish plugins (open source or commercial)
|
||||||
|
- List plugins in third-party marketplaces
|
||||||
|
|
||||||
|
However, stella-ops.org may maintain an official plugin registry with quality/security
|
||||||
|
standards for listed plugins.
|
||||||
|
|
||||||
|
### Q12: Can MSPs provide plugins to their managed customers?
|
||||||
|
|
||||||
|
**A:** Yes, with these considerations:
|
||||||
|
|
||||||
|
1. **Plugin distribution:** MSPs can freely distribute plugins to customers
|
||||||
|
2. **Stella Ops licensing:** Each customer deployment must comply with BUSL-1.1:
|
||||||
|
- Within free tier limits; OR
|
||||||
|
- Covered by MSP's commercial license; OR
|
||||||
|
- Customer has their own commercial license
|
||||||
|
|
||||||
|
See `docs/legal/SAAS_MSP_GUIDANCE.md` for detailed MSP scenarios.
|
||||||

|
||||||
|
|
||||||
|
## Edge Cases
|
||||||
|
|
||||||
|
### Q13: Does the Community Plugin Grant apply to unofficial API integrations?
|
||||||
|
|
||||||
|
**A:** The grant specifically covers plugins using "documented public plugin APIs or
|
||||||
|
integration points." For unofficial or undocumented APIs:
|
||||||
|
|
||||||
|
- Using undocumented APIs is at your own risk (they may change without notice)
|
||||||
|
- The Community Plugin Grant still applies if you're not modifying source code
|
||||||
|
- Relying on internal implementation details may create a derivative work
|
||||||
|
|
||||||
|
**Recommendation:** Use documented APIs for stable, supported integration.
|
||||||
|
|
||||||
|
### Q14: Can I fork Stella Ops and call it something else?
|
||||||
|
|
||||||
|
**A:** Forking is allowed under BUSL-1.1, but:
|
||||||
|
|
||||||
|
1. **BUSL-1.1 applies to the fork** - Production use requires compliance with the
|
||||||
|
Additional Use Grant or a commercial license
|
||||||
|
2. **Attribution required** - You must preserve LICENSE, NOTICE, and copyright notices
|
||||||
|
3. **No trademark use** - You may not use Stella Ops trademarks for your fork
|
||||||
|
4. **Change Date applies** - After the Change Date (2030-01-20), the fork converts to
|
||||||
|
Apache-2.0
|
||||||
|
|
||||||
|
### Q15: What if my plugin becomes popular and used beyond free tier limits?
|
||||||
|
|
||||||
|
**A:** Success is good! If your plugin enables usage beyond free tier limits:
|
||||||
|
|
||||||
|
1. **Users are responsible for licensing** - Not you as the plugin developer
|
||||||
|
2. **Consider partnership** - Contact stella-ops.org about potential partnership or
|
||||||
|
revenue sharing arrangements
|
||||||
|
3. **Document clearly** - Ensure your plugin documentation explains licensing requirements
|
||||||
|
|
||||||
|
### Q16: Can I host a free scanning service for the community using my plugin?
|
||||||
|
|
||||||
|
**A:** The BUSL-1.1 restriction specifically targets "public multi-tenant **paid** hosting."
|
||||||
|
Non-commercial, free-of-charge hosting for community benefit may be eligible for the
|
||||||
|
Community Program.
|
||||||
|
|
||||||
|
**Potentially eligible:**
|
||||||
|
- Free scanning for open source projects
|
||||||
|
- Academic/educational free access
|
||||||
|
- Non-profit services for other non-profits
|
||||||
|
|
||||||
|
**Not eligible (requires commercial license):**
|
||||||
|
- "Free tier" that upsells to paid services
|
||||||
|
- Free scanning bundled with paid consulting
|
||||||
|
- Any scenario where the free service drives commercial revenue
|
||||||
|
|
||||||
|
**Process:** Apply to the Community Program at community@stella-ops.org. Approval is
|
||||||
|
not automatic and is evaluated based on genuine community benefit.
|
||||||
|
|
||||||
|
See `docs/legal/SAAS_MSP_GUIDANCE.md` Section 4.3 for detailed guidance.

# SaaS and MSP Licensing Guidance
|
||||||
|
|
||||||
|
**Document Version:** 1.0.0
|
||||||
|
**Last Updated:** 2026-01-25
|
||||||
|
|
||||||
|
This document provides detailed guidance on Stella Ops licensing for SaaS providers,
|
||||||
|
Managed Service Providers (MSPs), and hosting scenarios. For the full legal terms,
|
||||||
|
see `LICENSE-ADDENDUM-COMMUNITY-PLUGIN-GRANT.md`.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
The Stella Ops BUSL-1.1 license with Community Plugin Grant restricts providing Stella
|
||||||
|
Ops as a commercial hosted service to third parties. This document clarifies what is
|
||||||
|
and isn't permitted under different hosting scenarios.
|
||||||
|
|
||||||
|
**Key Principle:** The restriction targets commercial offerings that compete with
|
||||||
|
Stella Ops' own hosted services, not legitimate internal use or isolated customer
|
||||||
|
deployments.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. Prohibited: Multi-Tenant SaaS Offerings
|
||||||
|
|
||||||
|
The following are **NOT permitted** without a commercial license:
|
||||||
|
|
||||||
|
### 1.1 Public SaaS Platform
|
||||||
|
|
||||||
|
**Prohibited:** Operating a multi-tenant SaaS platform that provides Stella Ops
|
||||||
|
functionality to paying customers.
|
||||||
|
|
||||||
|
**Example (prohibited):**
|
||||||
|
```
|
||||||
|
AcmeScan.io
|
||||||
|
├── Customer A (paying subscriber)
|
||||||
|
├── Customer B (paying subscriber)
|
||||||
|
├── Customer C (paying subscriber)
|
||||||
|
└── Shared Stella Ops infrastructure
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why prohibited:** This directly competes with Stella Ops' commercial SaaS offering.
|
||||||
|
|
||||||
|
### 1.2 White-Label Hosting
|
||||||
|
|
||||||
|
**Prohibited:** Rebranding Stella Ops and selling it as your own hosted product.
|
||||||
|
|
||||||
|
**Example (prohibited):**
|
||||||
|
```
|
||||||
|
"PowerScan Pro" (white-labeled Stella Ops)
|
||||||
|
├── Sold as monthly subscription
|
||||||
|
├── Marketed as proprietary technology
|
||||||
|
└── Runs on shared infrastructure
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why prohibited:** This is commercial redistribution as a competing service.
|
||||||
|
|
||||||
|
### 1.3 Embedded SaaS Features
|
||||||
|
|
||||||
|
**Prohibited:** Embedding Stella Ops scanning as a feature in your commercial SaaS product.
|
||||||
|
|
||||||
|
**Example (prohibited):**
|
||||||
|
```
|
||||||
|
AcmeDevPlatform.com (commercial SaaS)
|
||||||
|
├── Code repository feature
|
||||||
|
├── CI/CD pipeline feature
|
||||||
|
├── "Security Scanning" feature <- Powered by embedded Stella Ops
|
||||||
|
└── Charged as part of subscription
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why prohibited:** Stella Ops functionality is being monetized as part of a third-party
|
||||||
|
service offering.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. Permitted: Internal Use
|
||||||
|
|
||||||
|
The following **ARE permitted** under the Community Plugin Grant:
|
||||||
|
|
||||||
|
### 2.1 Internal Enterprise Deployment
|
||||||
|
|
||||||
|
**Permitted:** Deploying Stella Ops for your organization's internal use.
|
||||||
|
|
||||||
|
**Example (permitted):**
|
||||||
|
```
|
||||||
|
Acme Corp Internal
|
||||||
|
├── Development team scans
|
||||||
|
├── Security team analysis
|
||||||
|
├── Compliance reporting
|
||||||
|
└── Accessed only by Acme employees/contractors
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why permitted:** Internal use for the licensee's own business operations.
|
||||||
|
|
||||||
|
### 2.2 Internal Platform Team
|
||||||
|
|
||||||
|
**Permitted:** A platform/DevOps team providing Stella Ops to internal development teams.
|
||||||
|
|
||||||
|
**Example (permitted):**
|
||||||
|
```
|
||||||
|
Acme Corp Platform Team
|
||||||
|
├── Hosts Stella Ops on internal infrastructure
|
||||||
|
├── Provides scanning service to:
|
||||||
|
│ ├── Team Alpha (internal)
|
||||||
|
│ ├── Team Beta (internal)
|
||||||
|
│ └── Team Gamma (internal)
|
||||||
|
└── All users are Acme employees
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why permitted:** All users are within the same organization.
|
||||||
|
|
||||||
|
### 2.3 Subsidiary/Affiliate Use
|
||||||
|
|
||||||
|
**Permitted:** Parent company hosting for subsidiaries under common control.
|
||||||
|
|
||||||
|
**Example (permitted):**
|
||||||
|
```
|
||||||
|
Acme Holdings
|
||||||
|
├── Acme Corp (subsidiary) - uses hosted Stella Ops
|
||||||
|
├── Acme Europe (subsidiary) - uses hosted Stella Ops
|
||||||
|
└── Acme Asia (subsidiary) - uses hosted Stella Ops
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why permitted:** Affiliates under common control are treated as one organization.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 3. Permitted with Conditions: MSP Single-Tenant Hosting
|
||||||
|
|
||||||
|
Managed Service Providers may host Stella Ops for customers under specific conditions.
|
||||||
|
|
||||||
|
### 3.1 Single-Tenant Isolated Deployments
|
||||||
|
|
||||||
|
**Permitted (with commercial license):** MSP hosting separate Stella Ops instances for
|
||||||
|
each customer.
|
||||||
|
|
||||||
|
**Example (permitted with commercial license):**
|
||||||
|
```
|
||||||
|
AcmeMSP Infrastructure
|
||||||
|
├── Customer A Instance (isolated)
|
||||||
|
│ ├── Dedicated Stella Ops deployment
|
||||||
|
│ ├── Customer A data only
|
||||||
|
│ └── Covered by AcmeMSP commercial license
|
||||||
|
├── Customer B Instance (isolated)
|
||||||
|
│ ├── Dedicated Stella Ops deployment
|
||||||
|
│ ├── Customer B data only
|
||||||
|
│ └── Covered by AcmeMSP commercial license
|
||||||
|
└── No shared infrastructure between customers
|
||||||
|
```
|
||||||
|
|
||||||
|
**Requirements:**
|
||||||
|
- Each instance must be fully isolated
|
||||||
|
- MSP must have commercial license covering all instances
|
||||||
|
- Or each customer must have their own commercial license
|
||||||
|
|
||||||
|
### 3.2 Customer-Licensed Deployments
|
||||||
|
|
||||||
|
**Permitted:** MSP managing infrastructure where customer holds the license.
|
||||||
|
|
||||||
|
**Example (permitted):**
|
||||||
|
```
|
||||||
|
AcmeMSP (infrastructure only)
|
||||||
|
├── Customer A Infrastructure
|
||||||
|
│ ├── Customer A's Stella Ops license
|
||||||
|
│ ├── MSP manages infrastructure
|
||||||
|
│ └── Customer controls license compliance
|
||||||
|
└── Customer B Infrastructure
|
||||||
|
├── Customer B's Stella Ops license
|
||||||
|
└── MSP manages infrastructure
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why permitted:** The customer (not MSP) is the licensee; MSP provides only
|
||||||
|
infrastructure management.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 4. Gray Areas: Guidance for Common Scenarios
|
||||||
|
|
||||||
|
### 4.1 Consulting with Temporary Access
|
||||||
|
|
||||||
|
**Scenario:** Security consultant deploys Stella Ops at client site for an engagement.
|
||||||
|
|
||||||
|
**Analysis:**
|
||||||
|
- If consultant's license: Consultant needs commercial license for third-party use
|
||||||
|
- If client's license: Client uses their free tier or commercial license
|
||||||
|
|
||||||
|
**Recommendation:** Client should obtain their own license; consultant assists with
|
||||||
|
deployment.
|
||||||
|
|
||||||
|
### 4.2 Training/Demo Environments
|
||||||
|
|
||||||
|
**Scenario:** Providing training environments with Stella Ops to external trainees.
|
||||||
|
|
||||||
|
**Analysis:**
|
||||||
|
- Temporary, non-production training: Generally permitted under non-production use
|
||||||
|
- Ongoing access for trainees: May require commercial license depending on duration
|
||||||
|
|
||||||
|
**Recommendation:** Contact legal@stella-ops.org for training program licensing.
|
||||||
|
|
||||||
|
### 4.3 Non-Commercial Community Hosting
|
||||||
|
|
||||||
|
**Scenario:** Hosting Stella Ops scanning as a free service for community benefit.
|
||||||
|
|
||||||
|
The BUSL-1.1 restriction specifically targets "public multi-tenant **paid** hosting."
|
||||||
|
Non-commercial hosting for community benefit may be eligible for the Community Program.
|
||||||
|
|
||||||
|
**Examples of potentially eligible scenarios:**
|
||||||
|
- Free scanning services for open source projects
|
||||||
|
- Academic/educational institutions providing free access to students
|
||||||
|
- Non-profit organizations providing free services to other non-profits
|
||||||
|
- Community-run instances for local developer communities
|
||||||
|
|
||||||
|
**Requirements for Community Program consideration:**
|
||||||
|
1. Service must be genuinely free (no fees, subscriptions, or required purchases)
|
||||||
|
2. Service must not be a loss-leader for commercial offerings
|
||||||
|
3. Service must not compete directly with Licensor's commercial offerings
|
||||||
|
4. Organization must apply and be approved by Licensor
|
||||||
|
|
||||||
|
**Analysis:**
|
||||||
|
- Non-commercial, community benefit: Contact community@stella-ops.org for evaluation
|
||||||
|
- If charging any fees: Requires commercial license (not eligible for Community Program)
|
||||||
|
- If bundled with paid services: Requires commercial license
|
||||||
|
|
||||||
|
**Recommendation:** Apply for Community Program at https://stella-ops.org/community
|
||||||
|
|
||||||
|
**Important:** Community Program approval is not automatic. Licensor reserves the right
|
||||||
|
to evaluate each application based on community benefit, competitive impact, and
|
||||||
|
alignment with program goals.
|
||||||
|
|
||||||
|
### 4.4 Reseller/Channel Partner
|
||||||
|
|
||||||
|
**Scenario:** Reselling Stella Ops commercial licenses with implementation services.
|
||||||
|
|
||||||
|
**Analysis:**
|
||||||
|
- Reselling licenses: Requires authorized reseller agreement
|
||||||
|
- Implementation services: Permitted under customer's license
|
||||||
|
|
||||||
|
**Recommendation:** Contact sales@stella-ops.org for reseller program details.

## 5. Compliance Checklist
|
||||||
|
|
||||||
|
### For Internal Deployments
|
||||||
|
|
||||||
|
- [ ] All users are employees, contractors, or affiliates of the licensee
|

|
||||||
|

|
||||||
|
- [ ] No third-party access to functionality
|
||||||
|
|
||||||
|

## 6. Decision Tree
|
||||||
|
|
||||||
|
```
|
||||||
|
Is Stella Ops functionality being provided to third parties?
|
||||||
|
│
|
||||||
|
├─ NO → Internal use permitted (within free tier or with commercial license)
|
||||||
|
│
|
||||||
|
└─ YES → Is it a commercial offering (paid or part of paid service)?
|
||||||
|
│
|
||||||
|
├─ NO (genuinely free, community benefit)
|
||||||
|
│ │
|
||||||
|
│ ├─ Apply for Community Program (community@stella-ops.org)
|
||||||
|
│ │
|
||||||
|
│ └─ If approved → Permitted under Community Program terms
|
||||||
|
│ If not approved → Commercial license required
|
||||||
|
│
|
||||||
|
└─ YES (paid, or free-as-loss-leader for paid services)
|
||||||
|
│
|
||||||
|
└─ Is each customer fully isolated (single-tenant)?
|
||||||
|
│
|
||||||
|
├─ NO → Commercial SaaS license required
|
||||||
|
│ (contact sales@stella-ops.org)
|
||||||
|
│
|
||||||
|
└─ YES → MSP single-tenant model
|
||||||
|
│
|
||||||
|
├─ MSP holds commercial license covering all instances
|
||||||
|
│ → Permitted
|
||||||
|
│
|
||||||
|
└─ Each customer holds their own license
|
||||||
|
→ Permitted (MSP provides infrastructure only)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Key distinction:** The restriction targets "public multi-tenant **paid** hosting."
|
||||||
|
Non-commercial hosting for genuine community benefit may qualify for the Community Program,
|
||||||
|
but requires explicit approval from Licensor.

## 7. Examples of Compliance Violations
|
||||||
|
|
||||||
|
The following are examples of arrangements that would violate the license:
|
||||||
|
|
||||||
|
1. **"Vulnerability Scanning as a Service"** - Public signup for scanning services
|
||||||
|
powered by Stella Ops without commercial license
|
||||||
|
|
||||||
|
2. **DevSecOps Platform Bundle** - Including Stella Ops scanning in a paid platform
|
||||||
|
subscription without commercial license
|
||||||
|
|
||||||
|
3. **Shared MSP Instance** - Multiple MSP customers sharing a single Stella Ops
|
||||||
|
deployment
|
||||||
|
|
||||||
|
4. **"Free Tier Arbitrage"** - Running multiple free-tier installations to serve
|
||||||
|
third-party customers
|
||||||
|
|
||||||
|
5. **Competitive Forking** - Forking Stella Ops and offering it as a competing
|
||||||
|
hosted service
|
||||||
|
|
||||||
|

|
||||||
|

# Tile-Proxy Service Design
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
The Tile-Proxy service acts as an intermediary between StellaOps clients and upstream Rekor transparency log APIs. It provides centralized tile caching, request coalescing, and offline support for air-gapped environments.
|
||||||
|
|
||||||
|
## Architecture
|
||||||
|
|
||||||
|
```
|
||||||
|
┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐
|
||||||
|
│ CI/CD Agents │────►│ Tile Proxy │────►│ Rekor API │
|
||||||
|
│ (StellaOps) │ │ (StellaOps) │ │ (Upstream) │
|
||||||
|
└─────────────────┘ └────────┬────────┘ └─────────────────┘
|
||||||
|
│
|
||||||
|
┌───────────────────────┼───────────────────────┐
|
||||||

|
||||||
|
▼ ▼ ▼
|
||||||
|
┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐
|
||||||
|
│ Tile Cache │ │ TUF Metadata │ │ Checkpoint │
|
||||||
|
│ (CAS Store) │ │ (TrustRepo) │ │ Cache │
|
||||||
|
└─────────────────┘ └─────────────────┘ └─────────────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
## Core Responsibilities
|
||||||
|
|
||||||
|
1. **Tile Proxying**: Forward tile requests to upstream Rekor, caching responses locally
|
||||||
|
2. **Content-Addressed Storage**: Store tiles by hash for deduplication and immutability
|
||||||
|
3. **TUF Integration**: Optionally validate metadata using TUF trust anchors
|
||||||
|
4. **Request Coalescing**: Deduplicate concurrent requests for the same tile
|
||||||
|
5. **Checkpoint Caching**: Cache and serve recent checkpoints
|
||||||
|
6. **Offline Mode**: Serve from cache when upstream is unavailable
|
||||||
|
|
||||||
|
## API Surface
|
||||||
|
|
||||||
|
### Proxy Endpoints (Passthrough)
|
||||||
|
|
||||||
|
| Endpoint | Description |
|
||||||
|
|----------|-------------|
|
||||||
|
| `GET /tile/{level}/{index}` | Proxy tile request (cache-through) |
|
||||||
|
| `GET /tile/{level}/{index}.p/{partialWidth}` | Proxy partial tile |
|
||||||
|
| `GET /checkpoint` | Proxy checkpoint request |
|
||||||
|
| `GET /api/v1/log/entries/{uuid}` | Proxy entry lookup |
|
||||||
|
|
||||||
|
### Admin Endpoints
|
||||||
|
|
||||||
|
| Endpoint | Description |
|
||||||
|
|----------|-------------|
|
||||||
|
| `GET /_admin/cache/stats` | Cache statistics (hits, misses, size) |
|
||||||
|
| `POST /_admin/cache/sync` | Trigger manual sync job |
|
||||||
|
| `DELETE /_admin/cache/prune` | Prune old tiles |
|
||||||
|
| `GET /_admin/health` | Health check |
|
||||||
|
| `GET /_admin/ready` | Readiness check |
|
||||||
|
|
||||||
|
## Caching Strategy
|
||||||
|
|
||||||
|
### Content-Addressed Tile Storage
|
||||||
|
|
||||||
|
Tiles are stored using content-addressed paths based on SHA-256 hash:
|
||||||
|
|
||||||
|
```
|
||||||
|
{cache_root}/
|
||||||
|
├── tiles/
|
||||||
|
│ ├── {origin_hash}/
|
||||||
|
│ │ ├── {level}/
|
||||||
|
│ │ │ ├── {index}.tile
|
||||||
|
│ │ │ └── {index}.meta.json
|
||||||
|
│ │ └── checkpoints/
|
||||||
|
│ │ └── {tree_size}.checkpoint
|
||||||
|
│ └── ...
|
||||||
|
└── metadata/
|
||||||
|
└── cache_stats.json
|
||||||
|
```
|
||||||
|
|
||||||
|
### Tile Metadata
|
||||||
|
|
||||||
|
Each tile has associated metadata:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"cachedAt": "2026-01-25T10:00:00Z",
|
||||||
|
"treeSize": 1050000,
|
||||||
|
"isPartial": false,
|
||||||
|
"contentHash": "sha256:abc123...",
|
||||||
|
"upstreamUrl": "https://rekor.sigstore.dev"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Eviction Policy
|
||||||
|
|
||||||
|
1. **LRU by Access Time**: Least recently accessed tiles evicted first
|
||||||
|
2. **Max Size Limit**: Configurable maximum cache size
|
||||||
|
3. **TTL Override**: Force re-fetch after configurable time (for checkpoints)
|
||||||
|
4. **Immutability Preservation**: Full tiles (width=256) never evicted unless explicitly pruned
|
||||||
|
|
||||||
|
## Request Coalescing
|
||||||
|
|
||||||
|
Concurrent requests for the same tile are coalesced:
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
// Pseudo-code for request coalescing
|
||||||
|
var key = $"{origin}/{level}/{index}";
|
||||||
|
if (_inflightRequests.TryGetValue(key, out var existing))
|
||||||
|
{
|
||||||
|
return await existing; // Wait for in-flight request
|
||||||
|
}
|
||||||
|
|
||||||
|
var tcs = new TaskCompletionSource<byte[]>();
|
||||||
|
_inflightRequests[key] = tcs.Task;
|
||||||
|
try
|
||||||
|
{
|
||||||
|
var tile = await FetchFromUpstream(origin, level, index);
|
||||||
|
tcs.SetResult(tile);
|
||||||
|
return tile;
|
||||||
|
}
|
||||||
|
finally
|
||||||
|
{
|
||||||
|
_inflightRequests.Remove(key);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## TUF Integration Point
|
||||||
|
|
||||||
|
When `TufValidationEnabled` is true:
|
||||||
|
|
||||||
|
1. Load service map from TUF to discover Rekor URL
|
||||||
|
2. Validate Rekor public key from TUF targets
|
||||||
|
3. Verify checkpoint signatures using TUF-loaded keys
|
||||||
|
4. Reject tiles if checkpoint signature invalid
|
||||||
|
|
||||||
|
## Upstream Failover
|
||||||
|
|
||||||
|
Support multiple upstream sources with failover:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tile_proxy:
|
||||||
|
upstreams:
|
||||||
|
- url: https://rekor.sigstore.dev
|
||||||
|
priority: 1
|
||||||
|
timeout: 30s
|
||||||
|
- url: https://rekor-mirror.internal
|
||||||
|
priority: 2
|
||||||
|
timeout: 10s
|
||||||
|
```
|
||||||
|
|
||||||
|
Failover behavior:
|
||||||
|
1. Try primary upstream first
|
||||||
|
2. On timeout/error, try next upstream
|
||||||
|
3. Cache successful source for subsequent requests
|
||||||
|
4. Reset failover state on explicit refresh
|
||||||
|
|
||||||
|
## Deployment Model
|
||||||
|
|
||||||
|
### Standalone Service
|
||||||
|
|
||||||
|
Run as dedicated service with persistent volume:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
services:
|
||||||
|
tile-proxy:
|
||||||
|
image: stellaops/tile-proxy:latest
|
||||||
|
ports:
|
||||||
|
- "8090:8080"
|
||||||
|
volumes:
|
||||||
|
- tile-cache:/var/cache/stellaops/tiles
|
||||||
|
- tuf-cache:/var/cache/stellaops/tuf
|
||||||
|
environment:
|
||||||
|
- TILE_PROXY__UPSTREAM_URL=https://rekor.sigstore.dev
|
||||||
|
- TILE_PROXY__TUF_URL=https://trust.stella-ops.org/tuf/
|
||||||
|
```
|
||||||
|
|
||||||
|
### Sidecar Mode
|
||||||
|
|
||||||
|
Run alongside attestor service:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
services:
|
||||||
|
attestor:
|
||||||
|
image: stellaops/attestor:latest
|
||||||
|
environment:
|
||||||
|
- ATTESTOR__REKOR_URL=http://localhost:8090 # Use sidecar
|
||||||
|
|
||||||
|
tile-proxy:
|
||||||
|
image: stellaops/tile-proxy:latest
|
||||||
|
network_mode: "service:attestor"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Metrics
|
||||||
|
|
||||||
|
Prometheus metrics exposed at `/_admin/metrics`:
|
||||||
|
|
||||||
|
| Metric | Type | Description |
|
||||||
|
|--------|------|-------------|
|
||||||
|
| `tile_proxy_cache_hits_total` | Counter | Total cache hits |
|
||||||
|
| `tile_proxy_cache_misses_total` | Counter | Total cache misses |
|
||||||
|
| `tile_proxy_cache_size_bytes` | Gauge | Current cache size |
|
||||||
|
| `tile_proxy_upstream_requests_total` | Counter | Upstream requests by status |
|
||||||
|
| `tile_proxy_request_duration_seconds` | Histogram | Request latency |
|
||||||
|
| `tile_proxy_sync_last_success_timestamp` | Gauge | Last successful sync time |
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
tile_proxy:
|
||||||
|
# Upstream Rekor configuration
|
||||||
|
upstream_url: https://rekor.sigstore.dev
|
||||||
|
tile_base_url: https://rekor.sigstore.dev/tile/
|
||||||
|
|
||||||
|
# TUF integration (optional)
|
||||||
|
tuf:
|
||||||
|
enabled: true
|
||||||
|
url: https://trust.stella-ops.org/tuf/
|
||||||
|
validate_checkpoint_signature: true
|
||||||
|
|
||||||
|
# Cache configuration
|
||||||
|
cache:
|
||||||
|
base_path: /var/cache/stellaops/tiles
|
||||||
|
max_size_gb: 10
|
||||||
|
eviction_policy: lru
|
||||||
|
checkpoint_ttl_minutes: 5
|
||||||
|
|
||||||
|
# Sync job configuration
|
||||||
|
sync:
|
||||||
|
enabled: true
|
||||||
|
schedule: "0 */6 * * *"
|
||||||
|
depth: 10000
|
||||||
|
|
||||||
|
# Request handling
|
||||||
|
coalescing:
|
||||||
|
enabled: true
|
||||||
|
max_wait_ms: 5000
|
||||||
|
|
||||||
|
# Failover
|
||||||
|
failover:
|
||||||
|
enabled: true
|
||||||
|
retry_count: 2
|
||||||
|
retry_delay_ms: 1000
|
||||||
|
```
|
||||||
|
|
||||||
|
## Security Considerations
|
||||||
|
|
||||||
|
1. **No Authentication by Default**: Designed for internal network use
|
||||||
|
2. **Optional mTLS**: Can enable client certificate validation
|
||||||
|
3. **Rate Limiting**: Optional rate limiting per client IP
|
||||||
|
4. **Audit Logging**: Log all cache operations for compliance
|
||||||
|
5. **Immutable Tiles**: Full tiles are never modified after caching
|
||||||
|
|
||||||
|
## Error Handling
|
||||||
|
|
||||||
|
| Scenario | Behavior |
|
||||||
|
|----------|----------|
|
||||||
|
| Upstream unavailable | Serve from cache if available; 503 otherwise |
|
||||||
|
| Invalid tile data | Reject, don't cache, log error |
|
||||||
|
| Cache full | Evict LRU tiles, continue serving |
|
||||||
|
| TUF validation fails | Reject request, return 502 |
|
||||||
|
| Checkpoint stale | Refresh from upstream, warn in logs |
|
||||||
|
|
||||||
|
## Future Enhancements
|
||||||
|
|
||||||
|
1. **Tile Prefetching**: Prefetch tiles for known verification patterns
|

# TUF Integration Guide
|
||||||
|
|
||||||
|
This guide explains how StellaOps uses The Update Framework (TUF) for secure trust
|
||||||
|
distribution and how to configure TUF-based trust management.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
TUF provides a secure method for distributing and updating trust anchors (public keys,
|
||||||
|
service endpoints) without requiring client reconfiguration. StellaOps uses TUF to:
|
||||||
|
|
||||||
|
- Distribute Rekor public keys for checkpoint verification
|
||||||
|
- Distribute Fulcio certificate chains for keyless signing
|
||||||
|
- Provide service endpoint discovery (Rekor, Fulcio URLs)
|
||||||
|
- Enable secure key rotation with grace periods
|
||||||
|
- Support offline verification with bundled trust state
|
||||||
|
|
||||||
|
## Architecture

## TUF Roles
|
||||||
|
|
||||||
|
### Root
|
||||||
|
- Signs the root metadata containing all role keys
|
||||||
|
- Highest trust level, rotates rarely
|
||||||
|
- Should be kept offline in secure storage (HSM, air-gapped system)
|
||||||
|
- Used only for initial setup and key rotation ceremonies
|
||||||
|
|
||||||
|
### Timestamp
|
||||||
|
- Signs timestamp metadata indicating freshness
|
||||||
|
- Must be refreshed frequently (default: daily)
|
||||||
|
- Clients reject metadata older than expiration
|
||||||
|
- Can be automated with short-lived credentials
|
||||||
|
|
||||||
|
### Snapshot
|
||||||
|
- Signs snapshot metadata listing current target versions
|
||||||
|
- Updated when targets change
|
||||||
|
- Prevents rollback attacks
|
||||||
|
|
||||||
|
### Targets
|
||||||
|
- Signs metadata for actual target files
|
||||||
|
- Lists hashes and sizes for verification
|
||||||
|
- Supports delegations for large repositories
|
||||||
|
|
||||||
|
## Configuration

## CLI Usage
|
||||||
|
|
||||||
|
### Initialize Trust
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Initialize with a TUF repository
|
||||||
|
stella trust init \
|
||||||
|
--tuf-url https://trust.yourcompany.com/tuf/ \
|
||||||
|
--service-map sigstore-services-v1 \
|
||||||
|
--pin rekor-key-v1 rekor-key-v2
|
||||||
|
|
||||||
|
# Initialize in offline mode with bundled metadata
|
||||||
|
stella trust init \
|
||||||
|
--tuf-url file:///path/to/bundled-trust/ \
|
||||||
|
--offline
|
||||||
|
```
|
||||||
|
|
||||||
|
### Sync Metadata
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Refresh TUF metadata
|
||||||
|
stella trust sync
|
||||||
|
|
||||||
|
# Force refresh even if fresh
|
||||||
|
stella trust sync --force
|
||||||
|
```
|
||||||
|
|
||||||
|
### Check Status
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Show current trust state
|
||||||
|
stella trust status
|
||||||
|
|
||||||
|
# Show with key details
|
||||||
|
stella trust status --show-keys --show-endpoints
|
||||||
|
```
|
||||||
|
|
||||||
|
### Export for Offline Use
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Export trust state
|
||||||
|
stella trust export --out ./trust-bundle/
|
||||||
|
|
||||||
|
# Create sealed snapshot with tiles
|
||||||
|
stella trust snapshot export \
|
||||||
|
--out ./snapshots/2026-01-25.tar.zst \
|
||||||
|
--depth 10000
|
||||||
|
```
|
||||||
|
|
||||||
|
### Import Offline Bundle
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Import trust bundle
|
||||||
|
stella trust import ./snapshots/2026-01-25.tar.zst \
|
||||||
|
--verify-manifest \
|
||||||
|
--reject-if-stale 7d
|
||||||
|
```
|
||||||
|
|
||||||
|
## Service Map
|
||||||
|
|
||||||
|
The service map (`sigstore-services-v1.json`) contains endpoint URLs for Sigstore
|
||||||
|
services. This enables endpoint changes without client reconfiguration.
|
||||||
|
|
||||||
|
### Schema
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"version": 1,
|
||||||
|
"rekor": {
|
||||||
|
"url": "https://rekor.sigstore.dev",
|
||||||
|
"log_id": "c0d23d6ad406973f9559f3ba2d1ca01f84147d8ffc5b8445c224f98b9591801d",
|
||||||
|
"public_key_target": "rekor-key-v1"
|
||||||
|
},
|
||||||
|
"fulcio": {
|
||||||
|
"url": "https://fulcio.sigstore.dev",
|
||||||
|
"root_cert_target": "fulcio-chain.pem"
|
||||||
|
},
|
||||||
|
"overrides": {
|
||||||
|
"staging": {
|
||||||
|
"rekor_url": "https://rekor.sigstage.dev"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Site-Local Overrides
|
||||||
|
|
||||||
|
Organizations can define environment-specific overrides:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
attestor:
|
||||||
|
trust_repo:
|
||||||
|
environment: staging # Use staging overrides from service map
|
||||||
|
```
|
||||||
|
|
||||||
|
## Key Rotation
|
||||||
|
|
||||||
|
TUF supports secure key rotation with grace periods:
|
||||||
|
|
||||||
|
1. **Add new key**: Publish new key while keeping old key active
|
||||||
|
2. **Grace period**: Clients sync and receive both keys
|
||||||
|
3. **Verify**: Ensure all clients have new key
|
||||||
|
4. **Revoke old key**: Remove old key from active set
|
||||||
|
|
||||||
|
See [Key Rotation Runbook](../../operations/key-rotation-runbook.md) for detailed procedures.
|
||||||
|
|
||||||
|
## Offline Mode
|
||||||
|
|
||||||
|
For air-gapped environments, StellaOps can operate with bundled TUF metadata:
|
||||||
|
|
||||||
|
1. Export trust state on connected system:
|
||||||
|
```bash
|
||||||
|
stella trust snapshot export --out ./bundle.tar.zst
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Transfer bundle to air-gapped system
|
||||||
|
|
||||||
|
3. Import on air-gapped system:
|
||||||
|
```bash
|
||||||
|
stella trust import ./bundle.tar.zst --offline
|
||||||
|
```
|
||||||
|
|
||||||
|
4. Verify attestations using bundled trust:
|
||||||
|
```bash
|
||||||
|
stella attest verify ./attestation.json --offline
|
||||||
|
```
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### "TUF metadata expired"
|
||||||
|
|
||||||
|
The timestamp hasn't been refreshed. On the TUF repository:
|
||||||
|
```bash
|
||||||
|
./scripts/update-timestamp.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
### "Unknown target"
|
||||||
|
|
||||||
|
The requested target doesn't exist in the repository:
|
||||||
|
```bash
|
||||||
|
./scripts/add-target.sh /path/to/target target-name
|
||||||
|
```
|
||||||
|
|
||||||
|
### "Signature verification failed"
|
||||||
|
|
||||||
|
Keys may have rotated. Force a sync:
|
||||||
|
```bash
|
||||||
|
stella trust sync --force
|
||||||
|
```
|
||||||
|
|
||||||
|
### "Service map not found"
|
||||||
|
|
||||||
|
Ensure the service map target name matches configuration:
|
||||||
|
```bash
|
||||||
|
stella trust status # Check service_map_target value
|
||||||
|
```
|
||||||
|
|
||||||
|
## Security Considerations
|
||||||
|
|
||||||
|
1. **Root Key Security**: Keep root key offline. Only use for initial setup and rotations.
|
||||||
|
|
||||||
|
2. **Timestamp Automation**: Automate timestamp updates but use short-lived credentials.
|
||||||
|
|
||||||
|
3. **Monitoring**: Monitor for failed TUF fetches - may indicate MITM or repository issues.
|
||||||
|
|
||||||
|
4. **Rollback Protection**: TUF prevents rollback attacks through version tracking.
|
||||||
|
|
||||||
|
5. **Freshness**: Configure appropriate freshness thresholds for your security requirements.

# Notification Quotas
|
||||||
|
|
||||||
|
This document describes the quota system for notification delivery.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Quotas ensure fair usage of the notification system across tenants.
|
||||||
|
|
||||||
|
## Quota Types
|
||||||
|
|
||||||
|
### Daily Limits
|
||||||
|
- Maximum notifications per day per tenant
|
||||||
|
- Maximum notifications per channel per day
|
||||||
|
|
||||||
|
### Rate Limits
|
||||||
|
- Maximum notifications per minute
|
||||||
|
- Maximum notifications per second per channel
|
||||||
|
|
||||||
|
### Size Limits
|
||||||
|
- Maximum payload size
|
||||||
|
- Maximum attachment count
|
||||||
|
|
||||||
|
## Quota Enforcement
|
||||||
|
|
||||||
|
Quota violations result in:
|
||||||
|
1. Notification is queued for later delivery
|
||||||
|
2. Tenant is notified of quota exceeded
|
||||||
|
3. Admin alert is triggered if threshold is reached
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
Quotas are configured per tenant and can be overridden by administrators.

# Notification Retries
|
||||||
|
|
||||||
|
This document describes the retry mechanism for failed notification deliveries.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
The retry system ensures reliable notification delivery even when temporary failures occur.
|
||||||
|
|
||||||
|
## Retry Strategy
|
||||||
|
|
||||||
|
### Exponential Backoff
|
||||||
|
- Initial delay: 5 seconds
|
||||||
|
- Maximum delay: 1 hour
|
||||||
|
- Backoff multiplier: 2x
|
||||||
|
|
||||||
|
### Retry Limits
|
||||||
|
- Maximum attempts: 10
|
||||||
|
- Maximum retry duration: 24 hours
|
||||||
|
|
||||||
|
### Retry Conditions
|
||||||
|
- Network errors: Always retry
|
||||||
|
- HTTP 5xx errors: Always retry
|
||||||
|
- HTTP 429 (rate limit): Retry with Retry-After header
|
||||||
|
- HTTP 4xx errors: Do not retry (permanent failure)
|
||||||
|
|
||||||
|
## Dead Letter Queue
|
||||||
|
|
||||||
|
Notifications that exceed retry limits are moved to the dead letter queue for:
|
||||||
|
- Manual inspection
|
||||||
|
- Automatic alerting
|
||||||
|
- Scheduled reprocessing
|
||||||
|
|
||||||
|
## Monitoring
|
||||||
|
|
||||||
|
Retry metrics are exposed for:
|
||||||
|
- Retry count per notification
|
||||||
|
- Success rate after retries
|
||||||
|
- Average retry duration

# Redaction Catalog
|
||||||
|
|
||||||
|
This document catalogs the redaction rules applied to notification payloads.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
The redaction catalog ensures that sensitive information is not exposed in notifications.
|
||||||
|
|
||||||
|
## Redaction Rules
|
||||||
|
|
||||||
|
### Personal Identifiable Information (PII)
|
||||||
|
- Email addresses are partially redacted
|
||||||
|
- IP addresses are anonymized
|
||||||
|
- User names are replaced with user IDs
|
||||||
|
|
||||||
|
### Credentials
|
||||||
|
- API keys are fully redacted
|
||||||
|
- Passwords are never included
|
||||||
|
- Tokens are truncated to first/last 4 characters
|
||||||
|
|
||||||
|
### Internal Data
|
||||||
|
- Internal URLs are replaced with public equivalents
|
||||||
|
- Database IDs are not exposed
|
||||||
|
- Stack traces are summarized
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
Redaction rules can be customized per tenant and notification channel.

# Tenant Approvals
|
||||||
|
|
||||||
|
This document describes the tenant approval process for notification delivery.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Tenant approvals ensure that notifications are only sent to approved tenants with proper configuration.
|
||||||
|
|
||||||
|
## Approval Process
|
||||||
|
|
||||||
|
1. Tenant submits a request for notification access
|
||||||
|
2. Admin reviews the request and approves/denies
|
||||||
|
3. Approved tenants can configure notification channels
|
||||||
|
|
||||||
|
## Security Considerations
|
||||||
|
|
||||||
|
- All approval decisions are logged for audit purposes
|
||||||
|
- Approvals can be revoked at any time
|
||||||
|
- Cross-tenant notifications are blocked by default

# Webhook Acknowledgment Hardening
|
||||||
|
|
||||||
|
This document describes the security measures for webhook acknowledgment validation.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Webhook acknowledgment hardening ensures that webhook deliveries are properly verified and acknowledged.
|
||||||
|
|
||||||
|
## Security Measures
|
||||||
|
|
||||||
|
- HMAC signature verification for all webhook payloads
|
||||||
|
- Timeout handling for slow webhook endpoints
|
||||||
|
- Retry logic with exponential backoff
|
||||||
|
- Dead letter queue for failed deliveries
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
Webhook endpoints must be configured with:
|
||||||
|
- Secret key for HMAC signing
|
||||||
|
- Signature header name
|
||||||
|
- Timeout duration
|
||||||
|
- Maximum retry attempts

# StellaOps Trust Bootstrap Guide
|
||||||
|
|
||||||
|
> Sprint: SPRINT_20260125_003 - WORKFLOW-001
|
||||||
|
> Last updated: 2026-01-25
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
This guide covers the initial trust setup for a new StellaOps deployment. Trust
|
||||||
|
bootstrap establishes the cryptographic foundations for secure attestation and
|
||||||
|
verification.
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
- StellaOps CLI installed (`stella` command available)
|
||||||
|
- Network access to TUF repository (or offline trust bundle)
|
||||||
|
- Sufficient permissions to create keys in `/etc/stellaops/keys/`
|
||||||
|
- For keyless mode: OIDC identity provider configured
|
||||||
|
|
||||||
|
## Quick Start
|
||||||
|
|
||||||
|
### Online Bootstrap
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Initialize trust from organization's TUF repository
|
||||||
|
./devops/scripts/bootstrap-trust.sh \
|
||||||
|
--tuf-url https://trust.example.com/tuf/ \
|
||||||
|
--pin rekor-key-v1
|
||||||
|
```
|
||||||
|
|
||||||
|
### Offline Bootstrap (Air-Gapped)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Import pre-packaged trust bundle
|
||||||
|
./devops/scripts/bootstrap-trust-offline.sh \
|
||||||
|
/media/usb/trust-bundle-2026-01-25.tar.zst
|
||||||
|
```
|
||||||
|
|
||||||
|
## Detailed Steps
|
||||||
|
|
||||||
|
### Step 1: Generate Signing Keys (Optional)
|
||||||
|
|
||||||
|
If using local signing keys (not keyless/OIDC):
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Create key directory
|
||||||
|
mkdir -p /etc/stellaops/keys
|
||||||
|
chmod 700 /etc/stellaops/keys
|
||||||
|
|
||||||
|
# Generate ECDSA P-256 signing key
|
||||||
|
stella keys generate \
|
||||||
|
--type ecdsa-p256 \
|
||||||
|
--out /etc/stellaops/keys/signing-key.pem
|
||||||
|
|
||||||
|
# Or use OpenSSL
|
||||||
|
openssl ecparam -name prime256v1 -genkey -noout \
|
||||||
|
-out /etc/stellaops/keys/signing-key.pem
|
||||||
|
chmod 600 /etc/stellaops/keys/signing-key.pem
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 2: Initialize TUF Client
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Initialize with your organization's TUF repository
|
||||||
|
stella trust init \
|
||||||
|
--tuf-url https://trust.example.com/tuf/ \
|
||||||
|
--service-map sigstore-services-v1 \
|
||||||
|
--pin rekor-key-v1 rekor-key-v2
|
||||||
|
|
||||||
|
# Verify initialization
|
||||||
|
stella trust status
|
||||||
|
```
|
||||||
|
|
||||||
|
The `--pin` option specifies which Rekor keys to trust. Pin multiple keys during
|
||||||
|
rotation periods.
|
||||||
|
|
||||||
|
### Step 3: Verify TUF Metadata
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Check trust status
|
||||||
|
stella trust status --show-keys --show-endpoints
|
||||||
|
|
||||||
|
# Expected output:
|
||||||
|
# TUF Repository: https://trust.example.com/tuf/
|
||||||
|
# Service Map: sigstore-services-v1
|
||||||
|
# Trusted Keys:
|
||||||
|
# - rekor-key-v1 (expires: 2027-01-01)
|
||||||
|
# - rekor-key-v2 (expires: 2028-01-01)
|
||||||
|
# Endpoints:
|
||||||
|
# - Rekor: https://rekor.sigstore.dev
|
||||||
|
# - Fulcio: https://fulcio.sigstore.dev
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 4: Test Sign/Verify Cycle
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Create a test payload
|
||||||
|
echo "StellaOps bootstrap test" > /tmp/test-payload.txt
|
||||||
|
|
||||||
|
# Sign with your key
|
||||||
|
stella sign /tmp/test-payload.txt \
|
||||||
|
--key /etc/stellaops/keys/signing-key.pem \
|
||||||
|
--out /tmp/test.sig
|
||||||
|
|
||||||
|
# Verify signature
|
||||||
|
stella verify /tmp/test-payload.txt \
|
||||||
|
--sig /tmp/test.sig
|
||||||
|
|
||||||
|
# Clean up
|
||||||
|
rm /tmp/test-payload.txt /tmp/test.sig
|
||||||
|
```
|
||||||
|
|
||||||
|
### Step 5: Test Rekor Submission (Online Only)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Create and submit an attestation
|
||||||
|
stella attest create /tmp/test-payload.txt \
|
||||||
|
--type stellaops.io/predicates/test@v1 \
|
||||||
|
--rekor-submit
|
||||||
|
|
||||||
|
# Verify inclusion in transparency log
|
||||||
|
stella attest verify /tmp/test-payload.txt \
|
||||||
|
--check-inclusion
|
||||||
|
```
|
||||||
|
|
||||||
|
## Offline Bootstrap
|
||||||
|
|
||||||
|
For air-gapped deployments without network access:
|
||||||
|
|
||||||
|
### Create Trust Bundle (Connected System)
|
||||||
|
|
||||||
|
On a system with network access, create a trust bundle:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
stella trust snapshot export \
|
||||||
|
--include-tiles \
|
||||||
|
--out trust-bundle-$(date +%Y-%m-%d).tar.zst
|
||||||
|
```
|
||||||
|
|
||||||
|
### Transfer and Import (Air-Gapped System)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Transfer bundle via USB, DVD, or approved data diode
|
||||||
|
# Then import:
|
||||||
|
./devops/scripts/bootstrap-trust-offline.sh \
|
||||||
|
/media/usb/trust-bundle-2026-01-25.tar.zst
|
||||||
|
|
||||||
|
# Optional: Reject stale bundles
|
||||||
|
./devops/scripts/bootstrap-trust-offline.sh \
|
||||||
|
/media/usb/trust-bundle-2026-01-25.tar.zst \
|
||||||
|
--reject-if-stale 7d
|
||||||
|
```
|
||||||
|
|
||||||
|
## Configuration Options
|
||||||
|
|
||||||
|
### TUF Client Configuration
|
||||||
|
|
||||||
|
After bootstrap, TUF client configuration is stored in:
|
||||||
|
`~/.local/share/StellaOps/TufCache/`
|
||||||
|
|
||||||
|
Key files:
|
||||||
|
- `root.json` - Root of trust (only updated via ceremony)
|
||||||
|
- `targets.json` - List of trusted targets
|
||||||
|
- `snapshot.json` - Point-in-time snapshot of targets
|
||||||
|
- `timestamp.json` - Freshness guarantee (regularly updated)
|
||||||
|
|
||||||
|
### Environment Variables
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Override cache directory
|
||||||
|
export STELLAOPS_TUF_CACHE=/custom/path
|
||||||
|
|
||||||
|
# Enable debug logging
|
||||||
|
export STELLAOPS_LOG_LEVEL=debug
|
||||||
|
|
||||||
|
# Offline mode (no network calls)
|
||||||
|
export STELLAOPS_OFFLINE=true
|
||||||
|
```
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Error: "TUF metadata verification failed"
|
||||||
|
|
||||||
|
The TUF root key may have been rotated. Obtain the new root.json from your
|
||||||
|
security team and re-bootstrap:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
stella trust init \
|
||||||
|
--tuf-url https://trust.example.com/tuf/ \
|
||||||
|
--root-json /path/to/new/root.json \
|
||||||
|
--force
|
||||||
|
```
|
||||||
|
|
||||||
|
### Error: "Rekor connectivity check failed"
|
||||||
|
|
||||||
|
1. Verify network access to Rekor endpoint
|
||||||
|
2. Check firewall rules for HTTPS (port 443)
|
||||||
|
3. Verify the Rekor URL in service map is correct
|
||||||
|
4. Try forcing a sync: `stella trust sync --force`
|
||||||
|
|
||||||
|
### Error: "Key not found in trust store"
|
||||||
|
|
||||||
|
The pinned key may not exist in the TUF repository. Check available keys:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
stella trust status --show-keys
|
||||||
|
```
|
||||||
|
|
||||||
|
### Offline: "Bundle is stale"
|
||||||
|
|
||||||
|
The trust bundle exceeds the staleness threshold. Obtain a fresh bundle from a
|
||||||
|
connected system:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# On connected system
|
||||||
|
stella trust snapshot export --out fresh-bundle.tar.zst
|
||||||
|
|
||||||
|
# Transfer and import
|
||||||
|
./devops/scripts/bootstrap-trust-offline.sh fresh-bundle.tar.zst
|
||||||
|
```
|
||||||
|
|
||||||
|
## Maintenance
|
||||||
|
|
||||||
|
### Periodic Sync
|
||||||
|
|
||||||
|
Set up a cron job to keep TUF metadata fresh:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Every 6 hours
|
||||||
|
0 */6 * * * /usr/local/bin/stella trust sync --quiet
|
||||||
|
```
|
||||||
|
|
||||||
|
### Updating Air-Gap Bundles
|
||||||
|
|
||||||
|
For air-gapped systems, schedule regular bundle updates based on your
|
||||||
|
organization's freshness requirements (typically 7-30 days).
|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
|
||||||
|
- Configure CI/CD to use the signing key
|
||||||
|
- Set up key rotation procedures (see `key-rotation-runbook.md`)
|
||||||
|
- Configure monitoring for trust state freshness
|
||||||
|
- For air-gap: Establish bundle transfer schedule
|
||||||

# StellaOps Disaster Recovery Guide
|
||||||
|
|
||||||
|
> Sprint: SPRINT_20260125_003 - WORKFLOW-003
|
||||||
|
> Last updated: 2026-01-25
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
This guide covers disaster recovery procedures for StellaOps trust
|
||||||
|
infrastructure, including Rekor outages, key compromise, and TUF repository
|
||||||
|
failures.
|
||||||
|
|
||||||
|
## Scenario 1: Rekor Service Outage
|
||||||
|
|
||||||
|
### Symptoms
|
||||||
|
- Attestation submissions failing
|
||||||
|
- Verification requests timing out
|
||||||
|
- Circuit breaker reporting OPEN state
|
||||||
|
|
||||||
|
### Immediate Actions
|
||||||
|
|
||||||
|
1. **Verify the outage**
|
||||||
|
```bash
|
||||||
|
# Check Rekor health
|
||||||
|
curl -sf https://rekor.sigstore.dev/api/v1/log | jq .
|
||||||
|
|
||||||
|
# Check circuit breaker state
|
||||||
|
stella trust status --show-circuit-breaker
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Check if mirror is active**
|
||||||
|
```bash
|
||||||
|
# If mirror failover is enabled, verify it's working
|
||||||
|
stella trust status --show-backends
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **If mirror is not available, swap endpoints via TUF**
|
||||||
|
```bash
|
||||||
|
# On TUF repository admin system
|
||||||
|
./devops/scripts/disaster-swap-endpoint.sh \
|
||||||
|
--repo /path/to/tuf \
|
||||||
|
--new-rekor-url https://rekor-mirror.internal:8080 \
|
||||||
|
--note "Emergency: Production Rekor outage $(date -u)"
|
||||||
|
```
|
||||||
|
|
||||||
|
4. **Publish the update**
|
||||||
|
```bash
|
||||||
|
cd /path/to/tuf
|
||||||
|
./scripts/sign-metadata.sh # Sign updated metadata
|
||||||
|
./scripts/publish.sh # Deploy to TUF server
|
||||||
|
```
|
||||||
|
|
||||||
|
5. **Force client sync (optional, for immediate effect)**
|
||||||
|
```bash
|
||||||
|
stella trust sync --force
|
||||||
|
```
|
||||||
|
|
||||||
|
### Key Principle
|
||||||
|
|
||||||
|
**No client reconfiguration required.** Endpoint changes flow through TUF.
|
||||||
|
Clients discover new endpoints within their configured refresh interval.
|
||||||
|
|
||||||
|
### Recovery
|
||||||
|
|
||||||
|
Once the primary Rekor is restored:
|
||||||
|
|
||||||
|
1. **Swap back to primary**
|
||||||
|
```bash
|
||||||
|
./devops/scripts/disaster-swap-endpoint.sh \
|
||||||
|
--repo /path/to/tuf \
|
||||||
|
--new-rekor-url https://rekor.sigstore.dev \
|
||||||
|
--note "Recovery: Primary Rekor restored"
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Verify service map published**
|
||||||
|
```bash
|
||||||
|
stella trust sync --force
|
||||||
|
stella trust status --show-endpoints
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Reset circuit breakers**
|
||||||
|
```bash
|
||||||
|
stella trust reset-circuits
|
||||||
|
```
|
||||||
|
|
||||||
|
## Scenario 2: Rekor Key Compromise
|
||||||
|
|
||||||
|
### Symptoms
|
||||||
|
- Security team reports potential key exposure
|
||||||
|
- Unusual entries in transparency log
|
||||||
|
- Third-party security advisory
|
||||||
|
|
||||||
|
### Immediate Actions
|
||||||
|
|
||||||
|
1. **Assess the compromise scope**
|
||||||
|
- When was the key potentially exposed?
|
||||||
|
- What entries may be affected?
|
||||||
|
- Are there signed entries from the compromised period?
|
||||||
|
|
||||||
|
2. **Emergency key rotation**
|
||||||
|
```bash
|
||||||
|
# Phase 1: Add new key immediately (no grace period)
|
||||||
|
./devops/scripts/rotate-rekor-key.sh add-key \
|
||||||
|
--repo /path/to/tuf \
|
||||||
|
--new-key /secure/new-rekor-key-v2.pub
|
||||||
|
|
||||||
|
# Sign and publish immediately
|
||||||
|
cd /path/to/tuf
|
||||||
|
./scripts/sign-metadata.sh
|
||||||
|
./scripts/publish.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Force all clients to sync**
|
||||||
|
- Announce emergency update to all teams
|
||||||
|
- Clients should run: `stella trust sync --force`
|
||||||
|
|
||||||
|
4. **Revoke compromised key immediately**
|
||||||
|
```bash
|
||||||
|
# Phase 2: Remove old key (skip grace period due to compromise)
|
||||||
|
./devops/scripts/rotate-rekor-key.sh remove-old \
|
||||||
|
--repo /path/to/tuf \
|
||||||
|
--old-key-name rekor-key-v1
|
||||||
|
|
||||||
|
# Sign and publish
|
||||||
|
cd /path/to/tuf
|
||||||
|
./scripts/sign-metadata.sh
|
||||||
|
./scripts/publish.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
5. **Document the incident**
|
||||||
|
- Log rotation time
|
||||||
|
- Affected key ID and fingerprint
|
||||||
|
- List of potentially affected entries
|
||||||
|
- Remediation steps taken
|
||||||
|
|
||||||
|
### Forensics
|
||||||
|
|
||||||
|
Identify entries signed during the compromise window:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Query entries by time range
|
||||||
|
stella rekor query \
|
||||||
|
--after "2026-01-20T00:00:00Z" \
|
||||||
|
--before "2026-01-25T00:00:00Z" \
|
||||||
|
--key-id compromised-key-id
|
||||||
|
```
|
||||||
|
|
||||||
|
## Scenario 3: TUF Repository Unavailable
|
||||||
|
|
||||||
|
### Symptoms
|
||||||
|
- Clients cannot sync trust metadata
|
||||||
|
- `stella trust sync` failing with network errors
|
||||||
|
- TUF timestamp verification failing
|
||||||
|
|
||||||
|
### Immediate Actions
|
||||||
|
|
||||||
|
1. **Diagnose the issue**
|
||||||
|
```bash
|
||||||
|
# Check TUF repository health
|
||||||
|
curl -sf https://trust.example.com/tuf/timestamp.json | jq .
|
||||||
|
|
||||||
|
# Check DNS resolution
|
||||||
|
nslookup trust.example.com
|
||||||
|
|
||||||
|
# Check TLS certificate
|
||||||
|
openssl s_client -connect trust.example.com:443 -servername trust.example.com
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **For clients - extend offline tolerance**
|
||||||
|
```bash
|
||||||
|
# Temporarily allow stale metadata (use with caution)
|
||||||
|
stella trust sync --allow-stale --max-age 7d
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Restore TUF server**
|
||||||
|
- Check hosting infrastructure
|
||||||
|
- Restore from backup if needed
|
||||||
|
- Verify metadata integrity
|
||||||
|
|
||||||
|
4. **Deploy mirror (if available)**
|
||||||
|
```bash
|
||||||
|
# Update DNS or load balancer to point to mirror
|
||||||
|
# Or update clients directly (less preferred)
|
||||||
|
stella trust init \
|
||||||
|
--tuf-url https://trust-mirror.example.com/tuf/ \
|
||||||
|
--force
|
||||||
|
```
|
||||||
|
|
||||||
|
## Scenario 4: Signing Key Compromise
|
||||||
|
|
||||||
|
### Symptoms
|
||||||
|
- Security team reports key exposure
|
||||||
|
- Unauthorized attestations appearing
|
||||||
|
|
||||||
|
### Immediate Actions
|
||||||
|
|
||||||
|
1. **Revoke the compromised key**
|
||||||
|
```bash
|
||||||
|
./devops/scripts/rotate-signing-key.sh retire \
|
||||||
|
--old-key compromised-key-name
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Generate new signing key**
|
||||||
|
```bash
|
||||||
|
./devops/scripts/rotate-signing-key.sh generate \
|
||||||
|
--key-type ecdsa-p256
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Update CI/CD immediately**
|
||||||
|
- Remove compromised key from all pipelines
|
||||||
|
- Add new key
|
||||||
|
- Trigger rebuild of recent releases
|
||||||
|
|
||||||
|
4. **Notify downstream consumers**
|
||||||
|
- Announce key rotation
|
||||||
|
- Provide new public key
|
||||||
|
- Advise re-verification of recent attestations
|
||||||
|
|
||||||
|
## Scenario 5: Root Key Ceremony Required
|
||||||
|
|
||||||
|
### When Required
|
||||||
|
- Scheduled root key rotation (typically annual)
|
||||||
|
- Root key compromise (emergency)
|
||||||
|
- Threshold change for root signatures
|
||||||
|
|
||||||
|
### Procedure
|
||||||
|
|
||||||
|
1. **Schedule ceremony**
|
||||||
|
- Require M-of-N key holders present
|
||||||
|
- Air-gapped ceremony machine
|
||||||
|
- Hardware security modules
|
||||||
|
|
||||||
|
2. **Generate new root**
|
||||||
|
```bash
|
||||||
|
# On air-gapped ceremony machine
|
||||||
|
tuf-ceremony init \
|
||||||
|
--threshold 3 \
|
||||||
|
--keys 5 \
|
||||||
|
--algorithm ed25519
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Sign new root with old keys**
|
||||||
|
- Requires old threshold of signatures
|
||||||
|
- Ensures continuous trust chain
|
||||||
|
|
||||||
|
4. **Distribute new root**
|
||||||
|
- Publish to TUF repository
|
||||||
|
- Update bootstrap documentation
|
||||||
|
- Notify all operators
|
||||||
|
|
||||||
|
### Air-Gap Considerations
|
||||||
|
|
||||||
|
For air-gapped deployments after root rotation:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Export new trust bundle with updated root
|
||||||
|
stella trust snapshot export \
|
||||||
|
--include-root \
|
||||||
|
--out post-rotation-bundle.tar.zst
|
||||||
|
|
||||||
|
# Transfer and import on air-gapped systems
|
||||||
|
./devops/scripts/bootstrap-trust-offline.sh \
|
||||||
|
post-rotation-bundle.tar.zst \
|
||||||
|
--force # Required due to root change
|
||||||
|
```
|
||||||
|
|
||||||
|

## TUF-Based Key Rotation
|
||||||
|
|
||||||
|
> Sprint: SPRINT_20260125_003 - WORKFLOW-007
|
||||||
|
|
||||||
|
For organizations using TUF-based trust distribution, additional key rotation
|
||||||
|
procedures apply to Rekor public keys and TUF metadata signing keys.
|
||||||
|
|
||||||
|
### Rekor Public Key Rotation
|
||||||
|
|
||||||
|
Rekor public keys verify transparency log signatures. Rotation uses a dual-key
|
||||||
|
grace period to ensure all clients sync the new key before removing the old one.
|
||||||
|
|
||||||
|
**Recommended rotation interval:** Annually
|
||||||
|
**Grace period:** 7-14 days
|
||||||
|
|
||||||
|
#### Phase 1: Add New Key
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Add new Rekor key to TUF repository
|
||||||
|
./devops/scripts/rotate-rekor-key.sh add-key \
|
||||||
|
--repo /path/to/tuf \
|
||||||
|
--new-key rekor-key-v2.pub
|
||||||
|
|
||||||
|
# Sign and publish TUF metadata
|
||||||
|
cd /path/to/tuf
|
||||||
|
./scripts/sign-metadata.sh
|
||||||
|
./scripts/publish.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Phase 2: Grace Period
|
||||||
|
|
||||||
|
During the grace period (7-14 days):
|
||||||
|
- Monitor client sync logs
|
||||||
|
- Verify both keys work for verification
|
||||||
|
- Confirm all clients have updated
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Check client trust status
|
||||||
|
stella trust status --show-keys
|
||||||
|
# Should show both rekor-key-v1 and rekor-key-v2
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Phase 3: Remove Old Key
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Remove old key after grace period
|
||||||
|
./devops/scripts/rotate-rekor-key.sh remove-old \
|
||||||
|
--repo /path/to/tuf \
|
||||||
|
--old-key-name rekor-key-v1
|
||||||
|
|
||||||
|
# Sign and publish
|
||||||
|
cd /path/to/tuf
|
||||||
|
./scripts/sign-metadata.sh
|
||||||
|
./scripts/publish.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
### TUF Root Key Rotation
|
||||||
|
|
||||||
|
TUF root keys are the ultimate trust anchor. Rotation is a high-ceremony
|
||||||
|
operation requiring M-of-N key holders.
|
||||||
|
|
||||||
|
**Recommended rotation interval:** 2-3 years
|
||||||
|
**Requires:** Key ceremony with multiple signers
|
||||||
|
|
||||||
|
See [Disaster Recovery](disaster-recovery.md#scenario-5-root-key-ceremony-required)
|
||||||
|
for full root key ceremony procedures.
|
||||||
|
|
||||||
|
### TUF Metadata Signing Key Rotation
|
||||||
|
|
||||||
|
For targets, snapshot, and timestamp keys:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Generate new metadata signing key
|
||||||
|
openssl ecparam -name prime256v1 -genkey -noout \
|
||||||
|
-out /secure/targets-key-v2.pem
|
||||||
|
|
||||||
|
# Update root.json to include new key
|
||||||
|
tuf update-root --add-targets-key /secure/targets-key-v2.pem
|
||||||
|
|
||||||
|
# Sign with both old and new keys during transition
|
||||||
|
tuf sign targets --key /secure/targets-key-v1.pem
|
||||||
|
tuf sign targets --key /secure/targets-key-v2.pem
|
||||||
|
|
||||||
|
# After grace period, remove old key from root.json
|
||||||
|
tuf update-root --remove-targets-key /secure/targets-key-v1.pem
|
||||||
|
```
|
||||||
|
|
||||||
|
### Automated Scripts
|
||||||
|
|
||||||
|
Use the provided automation scripts:
|
||||||
|
|
||||||
|
| Script | Purpose |
