ARC-Core is a signal-intelligence event spine — a deterministic kernel built to host every project its author has ever developed, in tandem and smoothly, through one universal discipline: every state change is an event, every event produces a signed receipt, and every receipt is authority-gated.

Governed AI engineering control plane for local patch-test-verify workflows: explicit patches, allowlisted tests, tamper-evident receipts, verification summaries, and reviewable run bundles.
