# component_architecture_cli.md — **Stella Ops CLI** (2025Q4)
|
||
|
||
> **Scope.** Implementation‑ready architecture for **Stella Ops CLI**: command surface, process model, auth (Authority/DPoP), integration with Scanner/Excititor/Concelier/Signer/Attestor, Buildx plug‑in management, offline kit behavior, packaging, observability, security posture, and CI ergonomics.
|
||
|
||
---
|
||
|
||
## 0) Mission & boundaries
|
||
|
||
**Mission.** Provide a **fast, deterministic, CI‑friendly** command‑line interface to drive Stella Ops workflows:
|
||
|
||
* Build‑time SBOM generation via **Buildx generator** orchestration.
|
||
* Post‑build **scan/compose/diff/export** against **Scanner.WebService**.
|
||
* **Policy** operations and **VEX/Vuln** data pulls (operator tasks).
|
||
* **Verification** (attestation, referrers, signatures) for audits.
|
||
* Air‑gapped/offline **kit** administration.
|
||
|
||
**Boundaries.**
|
||
|
||
* CLI **never** signs; it only calls **Signer**/**Attestor** via backend APIs when needed (e.g., `report --attest`).
|
||
* CLI **does not** store long‑lived credentials beyond OS keychain; tokens are **short** (Authority OpToks).
|
||
* Heavy work (scanning, merging, policy) is executed **server‑side** (Scanner/Excititor/Concelier).
|
||

|
||
|
||
## 1) Solution layout & runtime form
|
||
|
||
```
|
||
src/
|
||
├─ StellaOps.Cli/ # net10.0 (Native AOT) single binary
|
||
├─ StellaOps.Cli.Core/ # verb plumbing, config, HTTP, auth
|
||
├─ StellaOps.Cli.Plugins/ # optional verbs packaged as plugins
|
||
├─ StellaOps.Cli.Tests/ # unit + golden-output tests
|
||
└─ packaging/
|
||
├─ msix / msi / deb / rpm / brew formula
|
||
└─ scoop manifest / winget manifest
|
||
```
|
||
|
||
**Language/runtime**: .NET 10 **Native AOT** for speed/startup; Linux builds use **musl** static when possible.
|
||
|
||
**Plug-in verbs.** Non-core verbs (Excititor, runtime helpers, future integrations) ship as restart-time plug-ins under `plugins/cli/**` with manifest descriptors. The launcher loads plug-ins on startup; hot reloading is intentionally unsupported. The inaugural bundle, `StellaOps.Cli.Plugins.NonCore`, packages the Excititor, runtime, and offline-kit command groups and publishes its manifest at `plugins/cli/StellaOps.Cli.Plugins.NonCore/`.
|
||
|
||
**OS targets**: linux‑x64/arm64, windows‑x64/arm64, macOS‑x64/arm64.
|
||
|
||
---
|
||
|
||
## 2) Command surface (verbs)
|
||
|
||
> All verbs default to **JSON** output when `--json` is set (CI mode). Human output is concise, deterministic.
|
||
|
||
### 2.1 Auth & profile
|
||
|
||
* `auth login`
|
||
|
||
* Modes: **device‑code** (default), **client‑credentials** (service principal).
|
||
* Produces **Authority** access token (OpTok) + stores **DPoP** keypair in OS keychain.
|
||
* `auth status` — show current issuer, subject, audiences, expiry.
|
||
* `auth logout` — wipe cached tokens/keys.
|
||
|
||
### 2.2 Build‑time SBOM (Buildx)
|
||
|
||
* `buildx install` — install/update the **StellaOps.Scanner.Sbomer.BuildXPlugin** on the host.
|
||
* `buildx verify` — ensure generator is usable.
|
||
* `buildx build` — thin wrapper around `docker buildx build --attest=type=sbom,generator=stellaops/sbom-indexer` with convenience flags:
|
||
|
||
* `--attest` (request Signer/Attestor via backend post‑push)
|
||
* `--provenance` pass‑through (optional)
|
||
|
||
### 2.3 Scanning & artifacts
|
||
|
||
* `scan image <ref|digest>`
|
||
|
||
* Options: `--force`, `--wait`, `--view=inventory|usage|both`, `--format=cdx-json|cdx-pb|spdx-json`, `--attest` (ask backend to sign/log).
|
||
* Streams progress; exits early unless `--wait`.
|
||
* `diff image --old <digest> --new <digest> [--view ...]` — show layer‑attributed changes.
|
||
* `export sbom <digest> [--view ... --format ... --out file]` — download artifact.
|
||
* `report final <digest> [--policy-revision ... --attest]` — request PASS/FAIL report from backend (policy+vex) and optional attestation.
|
||
|
||
### 2.4 Policy & data
|
||
|
||
* `policy get/set/apply` — fetch active policy, apply staged policy, compute digest.
|
||
* `concelier export` — trigger/export canonical JSON or Trivy DB (admin).
|
||
* `excititor export` — trigger/export consensus/raw claims (admin).
|
||
|
||
### 2.5 Verification
|
||
|
||
* `verify attestation --uuid <rekor-uuid> | --artifact <sha256> | --bundle <path>` — call **Attestor /verify** and print proof summary.
|
||
* `verify referrers <digest>` — ask **Signer /verify/referrers** (is image Stella‑signed?).
|
||
* `verify image-signature <ref|digest>` — standalone cosign verification (optional, local).
|
||
|
||
### 2.6 Runtime (Zastava helper)
|
||
|
||
* `runtime policy test --image/-i <digest> [--file <path> --ns <name> --label key=value --json]` — ask backend `/policy/runtime` like the webhook would (accepts multiple `--image`, comma/space lists, or stdin pipelines).
|
||
|
||
### 2.7 Offline kit
|
||
|
||
* `offline kit pull` — fetch latest **Concelier JSON + Trivy DB + Excititor exports** as a tarball from a mirror.
|
||
* `offline kit import <tar>` — upload the kit to on‑prem services (Concelier/Excititor).
|
||
* `offline kit status` — list current seed versions.
|
||
|
||
### 2.8 Utilities
|
||
|
||
* `config set/get` — endpoint & defaults.
|
||
* `whoami` — short auth display.
|
||
* `version` — CLI + protocol versions; release channel.
|
||
|
||
### 2.9 Aggregation-only guard helpers
|
||
|
||
* `sources ingest --dry-run --source <id> --input <path|uri> [--tenant ... --format table|json --output file]`
|
||
|
||
* Normalises documents (handles gzip/base64), posts them to the backend `aoc/ingest/dry-run` route, and exits non-zero when guard violations are detected.
|
||
* Defaults to table output with ANSI colour; `--json`/`--output` produce deterministic JSON for CI pipelines.
|
||
|
||
* `aoc verify [--since <ISO8601|duration>] [--limit <count>] [--sources list] [--codes list] [--format table|json] [--export file] [--tenant id] [--no-color]`
|
||
|
||
* Replays guard checks against stored raw documents. Maps backend `ERR_AOC_00x` codes onto deterministic exit codes so CI can block regressions.
|
||
* Supports pagination hints (`--limit`, `--since`), tenant scoping via `--tenant` or `STELLA_TENANT`, and JSON exports for evidence lockers.
|
||
|

|
||
|
||
## 3) AuthN: Authority + DPoP
|
||
|
||
### 3.1 Token acquisition
|
||
|
||
* **Device‑code**: the CLI opens an OIDC device code flow against **Authority**; the browser login is optional for service principals.
|
||
* **Client‑credentials**: service principals use **private_key_jwt** or **mTLS** to get tokens.
|
||
|
||
### 3.2 DPoP key management
|
||
|
||
* On first login, the CLI generates an **ephemeral JWK** (Ed25519) and stores it in the **OS keychain** (Keychain/DPAPI/KWallet/Gnome Keyring).
|
||
* Every request to backend services includes a **DPoP proof**; CLI refreshes tokens as needed.
|
||
|
||
### 3.3 Multi‑audience & scopes
|
||
|
||
* CLI requests **audiences** as needed per verb:
|
||
|
||
* `scanner` for scan/export/report/diff
|
||
* `signer` (indirect; usually backend calls Signer)
|
||
* `attestor` for verify
|
||
* `concelier`/`excititor` for admin verbs
|
||
|
||
CLI rejects verbs if required scopes are missing.
|
||
|
||
---
|
||
|
||
## 4) Process model & reliability
|
||
|
||
### 4.1 HTTP client
|
||
|
||
* Single **http2** client with connection pooling, DNS pinning, retry/backoff (idempotent GET/POST marked safe).
|
||
* **DPoP nonce** handling: on `401` with nonce challenge, CLI replays once.
|
||
|
||
### 4.2 Streaming
|
||
|
||
* `scan` and `report` support **server‑sent JSON lines** (progress events).
|
||
* `--json` prints machine events; human mode shows compact spinners and crucial updates only.
|
||
|
||
### 4.3 Exit codes (CI‑safe)
|
||
|
||
| Code | Meaning |
|
||
| ---- | ------------------------------------------- |
|
||
| 0 | Success |
|
||
| 2 | Policy fail (final report verdict=fail) |
|
||
| 3 | Verification failed (attestation/signature) |
|
||
| 4 | Auth error (invalid/missing token/DPoP) |
|
||
| 5 | Resource not found (image/SBOM) |
|
||
| 6 | Rate limited / quota exceeded |
|
||
| 7 | Backend unavailable (retryable) |
|
||
| 9 | Invalid arguments |
|
||
| 11–17 | Aggregation-only guard violation (`ERR_AOC_00x`) |
|
||
| 18 | Verification truncated (increase `--limit`) |
|
||
| 70 | Transport/authentication failure |
|
||
| 71 | CLI usage error (missing tenant, invalid cursor) |
|
||
|
||
---
|
||
|
||
## 5) Configuration model
|
||
|
||
**Precedence:** CLI flags → env vars → config file → defaults.
|
||
|
||
**Config file**: `${XDG_CONFIG_HOME}/stellaops/config.yaml` (Windows: `%APPDATA%\StellaOps\config.yaml`)
|
||
|
||
```yaml
|
||
cli:
|
||
authority: "https://authority.internal"
|
||
backend:
|
||
scanner: "https://scanner-web.internal"
|
||
attestor: "https://attestor.internal"
|
||
concelier: "https://concelier-web.internal"
|
||
excititor: "https://excititor-web.internal"
|
||
auth:
|
||
audienceDefault: "scanner"
|
||
deviceCode: true
|
||
output:
|
||
json: false
|
||
color: auto
|
||
tls:
|
||
caBundle: "/etc/ssl/certs/ca-bundle.crt"
|
||
offline:
|
||
kitMirror: "s3://mirror/stellaops-kit"
|
||
```
|
||
|
||
Environment variables: `STELLAOPS_AUTHORITY`, `STELLAOPS_SCANNER_URL`, etc.
|
||
|
||
---
|
||
|
||
## 6) Buildx generator orchestration
|
||
|
||
* `buildx install` locates the Docker root directory, writes the **generator** plugin manifest, and pulls `stellaops/sbom-indexer` image (pinned digest).
|
||
* `buildx build` wrapper injects:
|
||
|
||
* `--attest=type=sbom,generator=stellaops/sbom-indexer`
|
||
* `--label org.stellaops.request=sbom`
|
||
* Post‑build: CLI optionally calls **Scanner.WebService** to **verify referrers**, **compose** image SBOMs, and **attest** via Signer/Attestor.
|
||
|
||
**Detection**: If Buildx or generator unavailable, CLI falls back to **post‑build scan** with a warning.
|
||
|
||
---
|
||
|
||
## 7) Artifact handling
|
||
|
||
* **Downloads** (`export sbom`, `report final`): stream to file; compute sha256 on the fly; write sidecar `.sha256` and optional **verification bundle** (if `--bundle`).
|
||
* **Uploads** (`offline kit import`): chunked upload; retry on transient errors; show progress bar (unless `--json`).
|
||
|
||
---
|
||
|
||
## 8) Security posture
|
||
|
||
* **DPoP private keys** stored in **OS keychain**; metadata cached in config.
|
||
* **No plaintext tokens** on disk; short‑lived **OpToks** held in memory.
|
||
* **TLS**: verify backend certificates; allow custom CA bundle for on‑prem.
|
||
* **Redaction**: CLI logs remove `Authorization`, DPoP headers, PoE tokens.
|
||
* **Supply chain**: CLI distribution binaries are **cosign‑signed**; `stellaops version --verify` checks its own signature.
|
||
|
||
---
|
||
|
||
## 9) Observability
|
||
|
||
* `--verbose` adds request IDs, timings, and retry traces.
|
||
* **Metrics** (optional, disabled by default): Prometheus text file exporter for local monitoring in long‑running agents.
|
||
* **Structured logs** (`--json`): per‑event JSON lines with `ts`, `verb`, `status`, `latencyMs`.
|
||
|
||
---
|
||
|
||
## 10) Performance targets
|
||
|
||
* Startup ≤ **20 ms** (AOT).
|
||
* `scan image` request/response overhead ≤ **5 ms** (excluding server work).
|
||
* Buildx wrapper overhead negligible (<1 ms).
|
||
* Large artifact download (100 MB) sustained ≥ **80 MB/s** on local networks.
|
||
|
||
---
|
||
|
||
## 11) Tests & golden outputs
|
||
|
||
* **Unit tests**: argument parsing, config precedence, URL resolution, DPoP proof creation.
|
||
* **Integration tests** (Testcontainers): mock Authority/Scanner/Attestor; CI pipeline with fake registry.
|
||
* **Golden outputs**: verb snapshots for `--json` across OSes; kept in `tests/golden/…`.
|
||
* **Contract tests**: ensure API shapes match service OpenAPI; fail build if incompatible.
|
||

|
||
|
||
## 12) Error envelopes (human + JSON)
|
||
|
||
**Human:**
|
||
|
||
```
|
||
✖ Policy FAIL: 3 high, 1 critical (VEX suppressed 12)
|
||
- pkg:rpm/openssl (CVE-2025-12345) — affected (vendor) — fixed in 3.0.14
|
||
- pkg:npm/lodash (GHSA-xxxx) — affected — no fix
|
||
See: https://ui.internal/scans/sha256:...
|
||
Exit code: 2
|
||
```
|
||
|
||
**JSON (`--json`):**
|
||
|
||
```json
|
||
{ "event":"report", "status":"fail", "critical":1, "high":3, "url":"https://ui..." }
|
||
```
|
||
|
||
---
|
||
|
||
## 13) Admin & advanced flags
|
||
|
||
* `--authority`, `--scanner`, `--attestor`, `--concelier`, `--excititor` override config URLs.
|
||
* `--no-color`, `--quiet`, `--json`.
|
||
* `--timeout`, `--retries`, `--retry-backoff-ms`.
|
||
* `--ca-bundle`, `--insecure` (dev only; prints warning).
|
||
* `--trace` (dump HTTP traces to file; scrubbed).
|
||
|
||
---
|
||
|
||
## 14) Interop with other tools
|
||
|
||
* Emits **CycloneDX Protobuf** directly to stdout when `export sbom --format cdx-pb --out -`.
|
||
* Pipes to `jq`/`yq` cleanly in JSON mode.
|
||
* Can act as a **credential helper** for scripts: `stellaops auth token --aud scanner` prints a one‑shot token for curl.
|
||
|
||
---
|
||
|
||
## 15) Packaging & distribution
|
||
|
||
* **Installers**: deb/rpm (postinst registers completions), Homebrew, Scoop, Winget, MSI/MSIX.
|
||
* **Shell completions**: bash/zsh/fish/pwsh.
|
||
* **Update channel**: `stellaops self-update` (optional) fetches cosign‑signed release manifest; corporate environments can disable.
|
||
|
||
---
|
||
|
||
## 16) Security hard lines
|
||
|
||
* Refuse to print token values; redact Authorization headers in verbose output.
|
||
* Disallow `--insecure` unless `STELLAOPS_CLI_ALLOW_INSECURE=1` set (double opt‑in).
|
||
* Enforce **short token TTL**; refresh proactively when <30 s left.
|
||
* Device‑code cache binding to **machine** and **user** (protect against copy to other machines).

|
||
|
||
## 18) Roadmap (CLI)
|
||
|
||
* `scan fs <path>` (local filesystem tree) → upload to backend for analysis.
|
||
* `policy test --sbom <file>` (simulate policy results offline using local policy bundle).
|
||
* `runtime capture` (developer mode) — capture small `/proc/<pid>/maps` for troubleshooting.
|
||
* Pluggable output renderers for SARIF/HTML (admin‑controlled).
