+# Binary Analysis CLI Commands
+
+_Last updated: 2026-01-16_
+
+This guide documents the CLI-first binary analysis commands exposed by Stella Ops.
+
+---
+
+## `stella binary fingerprint export`
+
+Export a deterministic binary fingerprint (function hashes, section hashes, symbol table).
+
+### Usage
+
+```bash
+stella binary fingerprint export <artifact> \
+  --format json \
+  --output ./fingerprint.json
+```
+
+### Notes
+- Supported formats: `json`, `yaml`
+- Output is deterministic for identical inputs.
+- Use `--output` for offline workflows and evidence bundles.
+
+---
+
+## `stella binary diff`
+
+Compare two binaries and emit a function/symbol-level delta report.
+
+### Usage
+
+```bash
+stella binary diff <base> <candidate> \
+  --format table \
+  --scope function
+```
+
+### Notes
+- Supported formats: `json`, `table`
+- Scopes: `file`, `section`, `function`
+- Use `--format json` for automation and CI pipelines.
+
+---
+
+## Output contracts
+
+- All JSON outputs follow the CLI standard envelope (stable ordering, camelCase keys).
+- When used in evidence workflows, prefer `--format json` plus `--output` for deterministic artifacts.

+# Risk Provider Configuration Guide
+
+> **Module:** Policy Engine / RiskProfile  
+> **Sprint:** SPRINT_20260117_010_CLI_policy_engine (PEN-004)  
+> **Last Updated:** 2026-01-16
+
+This guide documents the configuration of risk providers within the Stella Ops Policy Engine. Risk providers supply signals (data points) used in risk scoring calculations.
+
+---
+
+## Overview
+
+Risk profiles define how vulnerability findings are scored and prioritized. Each profile consists of:
+
+1. **Signals** — Data sources that contribute to the risk assessment
+2. **Weights** — Relative importance of each signal (0.0–1.0)
+3. **Overrides** — Rules that modify severity or decisions based on signal combinations
+4. **Metadata** — Optional profile metadata
+
+---
+
+## Risk Profile Schema
+
+Risk profiles follow the `risk-profile-schema@1.json` schema. The canonical schema is available at:
+- **Schema URI:** `https://stellaops.dev/schemas/risk-profile-schema@1.json`
+- **Source:** `src/Policy/StellaOps.Policy.RiskProfile/Schemas/risk-profile-schema@1.json`
+
+### Required Properties
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `id` | string | Stable identifier (slug or URN) |
+| `version` | string | SemVer version (e.g., `1.0.0`) |
+| `signals` | array | Signal definitions (min 1) |
+| `weights` | object | Weight per signal name |
+| `overrides` | object | Severity and decision overrides |
+
+---
+
+## Signal Configuration
+
+Each signal definition requires:
+
+```json
+{
+  "name": "kev",
+  "source": "cisa",
+  "type": "boolean",
+  "path": "/evidence/kev/known",
+  "transform": null,
+  "unit": null
+}
+```
+
+### Signal Properties
+
+| Property | Required | Type | Description |
+|----------|:--------:|------|-------------|
+| `name` | ✅ | string | Logical signal key (e.g., `reachability`, `kev`, `exploit_chain`) |
+| `source` | ✅ | string | Upstream provider or calculation origin |
+| `type` | ✅ | enum | `boolean`, `numeric`, or `categorical` |
+| `path` | | string | JSON Pointer to the signal in the evidence document |
+| `transform` | | string | Transform applied before weighting (e.g., `log`, `normalize`) |
+| `unit` | | string | Unit for numeric signals |
+
+### Built-in Signal Sources
+
+| Source | Signal Names | Type | Description |
+|--------|-------------|------|-------------|
+| `cvss` | `base_score`, `temporal_score`, `environmental_score` | numeric | CVSS v4.0 scores |
+| `epss` | `probability`, `percentile` | numeric | EPSS v4 exploit prediction |
+| `cisa` | `kev` | boolean | Known Exploited Vulnerabilities |
+| `reachability` | `reachable`, `confidence`, `depth` | mixed | Reachability analysis results |
+| `vex` | `status`, `justification` | categorical | VEX consensus status |
+| `patch` | `available`, `verified` | boolean | Patch availability evidence |
+| `runtime` | `observed`, `observation_count` | mixed | Runtime signal correlation |
+
+---
+
+## Weight Configuration
+
+Weights determine the relative importance of each signal in the final risk score. Weights are normalized by the scoring engine.
+
+```json
+{
+  "weights": {
+    "base_score": 0.3,
+    "kev": 0.25,
+    "reachability": 0.25,
+    "epss_probability": 0.15,
+    "patch_available": 0.05
+  }
+}
+```
+
+**Weight Rules:**
+- Values must be between 0.0 and 1.0
+- Weights are normalized (sum to 1.0) at runtime
+- Missing signals receive zero contribution
+
+---
+
+## Override Configuration
+
+Overrides allow conditional severity adjustments and decision actions.
+
+### Severity Overrides
+
+```json
+{
+  "overrides": {
+    "severity": [
+      {
+        "when": { "kev": true, "reachable": true },
+        "set": "critical"
+      },
+      {
+        "when": { "patch_available": true, "reachable": false },
+        "set": "low"
+      }
+    ]
+  }
+}
+```
+
+**Severity Levels:** `critical`, `high`, `medium`, `low`, `informational`
+
+### Decision Overrides
+
+```json
+{
+  "overrides": {
+    "decisions": [
+      {
+        "when": { "kev": true },
+        "action": "deny",
+        "reason": "Active exploitation detected via CISA KEV"
+      },
+      {
+        "when": { "reachable": false, "vex_status": "not_affected" },
+        "action": "allow",
+        "reason": "Unreachable and verified not affected"
+      }
+    ]
+  }
+}
+```
+
+**Decision Actions:** `allow`, `review`, `deny`
+
+---
+

+    "vex_status": 0.05
+  },
+  "overrides": {
+    "severity": [
+      { "when": { "kev": true, "reachable": true }, "set": "critical" },
+      { "when": { "reachable": false }, "set": "low" }
+    ],
+    "decisions": [
+      { "when": { "kev": true, "reachable": true }, "action": "deny", "reason": "Active exploitation in reachable code" },
+      { "when": { "vex_status": "not_affected" }, "action": "allow", "reason": "VEX confirms not affected" }
+    ]
+  },
+  "metadata": {
+    "author": "platform-team",
+    "compliance": ["SOC2", "ISO27001"]
+  }
+}
+```
+
+---
+
+## CLI Commands
+
+### List Risk Profiles
+
+```bash
+stella policy profiles list --format table
+```
+
+### Show Profile Details
+
+```bash
+stella policy profiles show <profile-id> --format json
+```
+
+### Validate Profile
+
+```bash
+stella policy profiles validate profile.json
+```
+
+### Apply Profile
+
+```bash
+stella policy profiles apply <profile-id> --scope tenant:default
+```
+
+---
+
+## Configuration Files
+
+Risk profiles can be stored as YAML or JSON:
+
+- **Default location:** `etc/risk-profiles/`
+- **Environment variable:** `STELLA_RISK_PROFILES_PATH`
+- **Configuration key:** `policy:riskProfiles:path`
+
+### appsettings.yaml Example
+
+```yaml
+policy:
+  riskProfiles:
+    path: /etc/stella/risk-profiles
+    default: stella-default-v1
+    validation:
+      strict: true
+      allowUnknownSignals: false
+```
+
+---
+
+## Validation Rules
+
+1. **Schema validation** — Profile must conform to `risk-profile-schema@1.json`
+2. **Signal consistency** — All signals in `weights` must be defined in `signals`
+3. **Weight bounds** — All weights must be in [0.0, 1.0] range
+4. **Override predicates** — `when` clauses must reference valid signal names
+5. **Version format** — Must be valid SemVer
+
+### Validation Errors
+
+| Code | Description |
+|------|-------------|
+| `RISK_PROFILE_001` | Missing required property |
+| `RISK_PROFILE_002` | Invalid weight value |
+| `RISK_PROFILE_003` | Unknown signal in weights |
+| `RISK_PROFILE_004` | Invalid override predicate |
+| `RISK_PROFILE_005` | Version format invalid |
