One boundary for safe data access
The gateway accepts authenticated requests, passes them to a child process, and reaches V83.COMConnector. It serves receipts, sales, credit, cash operations, QR payments, and configuration knowledge.
What is covered
Access control
HMAC authentication, loopback child process, and read-only routes.
Configuration knowledge
341 objects and 1,471 explicit links, with no runtime errors or truncated samples.
Observability
Health, metadata, runtime, diagnostics, and signed restart.
Concurrent HTTP access and cached COM
ThreadingHTTPServer permits parallel worker threads while OneCClient keeps cached COM state without visible serialization or thread-local ownership. The fake-COM harness reproduced a lazy-init race in 49 of 50 runs, duplicate connections, and overlapping COM calls.
Evidence of an architectural risk, not proof of a production incident: real V83.COMConnector has not yet had a controlled read-only probe.
Check - decide - then change
- Baseline in a safe environment.
- Probe serial, then 2 and 4 identical read-only requests.
- Compare sequential server, lock, COM worker/queue, and thread-local connections.
- Release only after approval, regression, staged verification, and rollback plan.
