Enterprise-grade sandbox for high-concurrency asynchronous stream telemetry. 20× parallel inference lanes, cryptographic telemetry vault, and a production-grade observability stack — validated at 14.2K pps.
External payload stream enters through a token-bucket rate limiter (10K capacity · 500/s refill · 1.5× burst) and a tri-state fail-closed circuit breaker (5-failure threshold · 30 s recovery).
An asyncio event-loop scheduler boots 20 isolated parallel lanes in a staggered pattern. Each lane processes payloads independently with full fault isolation.
SHA-256 hash-chain vault records every event into an append-only tamper-evident ledger. Prometheus metrics export + structured JSON-line logger with trace/span context.
Async scheduler with staggered lane boot and full fault isolation across 20 parallel processing lanes.
Capacity control with 500 tokens/s refill rate and 1.5× burst headroom for traffic spikes.
5-failure threshold trips in 73 ms; 30-second automatic recovery window. Prevents cascading degradation.
Genesis-seeded cryptographic ledger — every event is hash-linked, making the log tamper-evident by design.
Structured logging with trace/span context injection. Compatible with Grafana Loki for log aggregation.
Multi-layer image build, non-root runtime user, healthcheck endpoint. Production-ready at 118 MiB.
