ARCHITECTURE SPECIFICATION

Edge PoP Ingress & Routing Topology

Technical specifications, authorization requirements, and protocol demultiplexing for node RU-SPB-01.

Technical Justification of the 4 Traffic Legs

Each traffic leg satisfies a distinct enterprise infrastructure requirement within the CI/CD build artifact and package distribution pipeline:

Remote Cache CAS ByteStream

Endpoint: cache.runner-ru.test-pr.space

Protocol: HTTPS / TCP 443 (HTTP/2 ByteStream)

Remote execution content-addressable storage. Provides unthrottled wire-speed upload and download of immutable CAS blobs, compiler output archives, and action caches for build runners.

Cluster Mesh Artifact Sync

Endpoint: sync.runner-ru.test-pr.space

Protocol: QUIC / UDP 443 (Real-Time Transport)

High-speed cluster artifact synchronization. Low-latency point-to-point mesh replication between regional PoP nodes to propagate freshly compiled dependencies across data centers.

Build Artifact & Package Mirror

Endpoint: repo-ru.test-pr.space

Protocol: HTTPS / TCP 443 (HTTP 206 Range)

Static build artifact and package distribution mirror. Serves pre-compiled toolchains, SDK bundles, and public manifests directly to client machines using CDN edge caching and byte-range resumption.

CI/CD Worker Coordinator API

Endpoint: api.runner-ru.test-pr.space

Protocol: HTTPS / TCP 443 (REST)

CI/CD worker authentication and status. Handles node registration, heartbeat telemetry, capacity drained notifications, and cryptographic session authorization.

Ingress & Routing Topology

Single-port edge ingress demultiplexing architecture based on TLS SNI inspection and protocol negotiation:

Authentication & Rate Limits

Channel Endpoint Auth Mechanism Rate Limits Unauthenticated Response
cache.runner-ru.test-pr.space Worker Session Token / mTLS Unthrottled transport (HTTP/2 ByteStream) HTTP 403 Forbidden
sync.runner-ru.test-pr.space Cluster Mesh Auth PSK Congestion-controlled line-rate Connection Reset (Drop)
repo-ru.test-pr.space Public Anonymous Read 1,000 req/min per IP (HTTP 206 Cache) Allowed (Public Access)
api.runner-ru.test-pr.space Cryptographic Bearer Token 120 req/min per Bearer token HTTP 401 Unauthorized

Public Manifests & Distribution Artifacts

Public build artifacts and toolchain packages are available under dist/v1/pkg/. Runners should verify SHA-256 cryptographic signatures prior to execution:
