Plugin assemblies loaded via PluginHost into isolated AssemblyLoadContexts produce distinct types even from the same DLL. When AppDomain.GetAssemblies() returns both Default and plugin-ALC copies, DI registration and IOptions<T> resolution silently fail (e.g. ValkeyTransportOptions defaulting to localhost). Applied AssemblyLoadContext.Default filter to all 7 assembly discovery sites: - MessagingServiceCollectionExtensions (transport plugin scan) - StellaRouterIntegrationHelper (transport plugin loader) - Gateway.WebService Program.cs (startup transport scan) - GeneratedEndpointDiscoveryProvider (endpoint provider scan) - ReflectionEndpointDiscoveryProvider (endpoint attribute scan) - ServiceCollectionExtensions (schema provider scan) - MigrationModulePluginDiscovery (migration plugin scan) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Stella Ops Suite Documentation
Stella Ops Suite is a centralized, auditable release control plane for non-Kubernetes container estates. It orchestrates environment promotions, gates releases using reachability-aware security and policy, and produces verifiable evidence for every decision.
Stella is designed for teams who deploy containers via Docker/Compose, hosts/VMs, and scripted automation and need certifiable security + auditable releases without building a bespoke governance pipeline.
What Stella delivers
Evidence-grade release governance (outside Kubernetes)
- Environment promotions (Dev -> Stage -> Prod) with explicit policy, approvals, and change control.
- Digest-first release identity: deployments are tracked by immutable OCI digests so "what is deployed where" is unambiguous.
- Deterministic decision records: every gate decision is explainable ("why blocked?") and replayable.
Reachability-aware security decisioning
- Deep scanning produces SBOM + findings + reachability and hybrid reachability evidence.
- VEX-first decisioning with consensus and conflict handling across issuers (SBOM/VEX are part of the evidence chain, not a side export).
- Policy-as-code with deterministic evaluation and traceable outcomes.
Verifiability, attestability, and audit export
- Evidence packets / decision capsules: hashable, immutable bundles that capture inputs, verdicts, and approvals.
- Attestations (DSSE/in-toto, predicates for SBOM/VEX/verdict/reachability; optional Sigstore flows where configured).
- Audit exports for compliance review, incident response, and forensic reconstruction.
Offline-first, sovereign operation
- Built for air-gapped and restricted environments: local databases, offline kits/snapshots, and deterministic replay.
- Regional crypto profiles (eIDAS/FIPS/GOST/SM and related plugin architecture) to avoid compliance lock-in.
Toolchain-agnostic integrations
- Integrates with common SCM/CI/registries/secrets managers through connectors and plugins.
- Works alongside existing pipelines: scan-on-build, gate-on-promotion, re-evaluate on advisory updates.
Core differentiators (the "why Stella" set)
These concepts appear throughout the docs and are the suite's anchor points:
- Signed, replayable risk verdicts: decisions can be re-run deterministically from the same evidence.
- Decision capsules: evidence is packaged for audit, not scattered across logs and screenshots.
- Reachability with portable proofs: exploitability is evidenced, not asserted.
- Smart-diff / semantic risk delta: focus on what materially changed between releases.
- Unknowns as first-class state: uncertainty is tracked and budgeted, not hidden.
- Non-Kubernetes-first: orchestration and evidence for Compose/hosts/agentless targets as a primary use case.
- Digest-first release identity: immutable artifacts, immutable accountability.

Design principles (non-negotiable)
- Offline-first: core operations must work in restricted/air-gapped environments.
- Deterministic replay: same inputs yield the same outputs (stable ordering, canonical hashing).
- Evidence-linked decisions: every decision links to concrete evidence artifacts.
- Digest-first identity: releases are immutable OCI digests, not mutable tags.
- Pluggable integrations: connectors and steps are extensible; the core evidence chain stays stable.
