- Created `StellaOps.TestKit.Tests` project for unit tests related to determinism. - Implemented `DeterminismManifestTests` to validate deterministic output for canonical bytes and strings, file read/write operations, and error handling for invalid schema versions. - Added `SbomDeterminismTests` to ensure identical inputs produce consistent SBOMs across SPDX 3.0.1 and CycloneDX 1.6/1.7 formats, including parallel execution tests. - Updated project references in `StellaOps.Integration.Determinism` to include the new determinism testing library.

# Router chaos testing
|
|
|
|
Purpose
|
|
- Validate backpressure, recovery, and cache failure behavior for the router.
|
|
|
|
Test categories
|
|
- Load testing with spike scenarios (baseline, 10x, 50x, recovery).
|
|
- Backpressure verification for 429 and 503 with Retry-After.
|
|
- Recovery tests to ensure queues drain quickly.
|
|
- Valkey failure injection with graceful fallback.
|
|
|
|
Expected behavior
|
|
- Normal load returns 200 OK.
|
|
- High load returns 429 with Retry-After.
|
|
- Critical load returns 503 with Retry-After.
|
|
- Recovery within 30 seconds, zero data loss.
|

Metrics
|
|
- http_requests_total{status}
|
|
- router_request_queue_depth
|
|
- request_recovery_seconds
|
|
|
|
Alert cues
|
|
- Throttle rate above 10% for 5 minutes.
|
|
- P95 recovery time above 30 seconds.
|
|
- Missing Retry-After headers.
|
|
|
|
CI integration
|
|
- Runs on PRs touching router code and nightly staging runs.
|
|
- Stores results as artifacts for audits.
