+- [ ] Register an `ITrafficRouter` implementation with `TrafficRouterRegistry` and verify lookup
+- [ ] Configure weighted routing (percentage-based) and verify traffic distribution
+- [ ] Configure header-based routing and verify requests with matching headers are routed correctly
+- [ ] Configure cookie-based routing and verify sticky session behavior
+- [ ] Verify routing state persistence: apply a routing rule, restart, and confirm the rule persists
+- [ ] Register a plugin router (Nginx/HAProxy/Traefik/ALB adapter) and verify it integrates with the framework

+# Version Sticker Writer (Deployment State Recording)
+
+## Module
+ReleaseOrchestrator
+
+## Status
+VERIFIED
+
+## Description
+Version sticker system that writes stella.version.json files to each deployment target via agents, recording deployment state (release, components, digests, environment, evidence IDs). Supports write and read operations for deployment verification.
+
+## Implementation Details
+- **Modules**: `src/ReleaseOrchestrator/__Libraries/StellaOps.ReleaseOrchestrator.Evidence/Sticker/`
+- **Key Classes**:
+  - `VersionStickerWriter` (`src/ReleaseOrchestrator/__Libraries/StellaOps.ReleaseOrchestrator.Evidence/Sticker/VersionStickerWriter.cs`) - writes stella.version.json files to deployment targets via agents
+  - `VersionStickerGenerator` (`src/ReleaseOrchestrator/__Libraries/StellaOps.ReleaseOrchestrator.Evidence/Sticker/VersionStickerGenerator.cs`) - generates version sticker content with release, components, digests, environment, and evidence IDs
+- **Interfaces**: `IVersionStickerWriter`, `IVersionStickerGenerator`
+- **Source**: SPRINT_20260110_109_003_RELEVI_version_sticker.md
+
+## E2E Test Plan
+- [ ] Generate a version sticker via `VersionStickerGenerator` and verify it contains release ID, component digests, environment, and evidence IDs
+- [ ] Write a version sticker to a deployment target via `VersionStickerWriter` and verify stella.version.json is created
+- [ ] Read back a version sticker from the target and verify it matches the written content
+- [ ] Deploy a new release and verify the version sticker is updated with the new release information
+- [ ] Verify the sticker includes immutable digests (not mutable tags) for all component references
