ZDDC
ea385b5366
ZDDC — Zero Day Document Control. A file-naming convention plus five single-file HTML tools (archive, transmittal, classifier, mdedit, landing) and an optional Go HTTP server (zddc-server) with ACL and a virtual archive index. Self-contained, offline-capable, dependency-free. See README.md for an overview, AGENTS.md and ARCHITECTURE.md for the build/release/architecture detail, bootstrap/README.md for the two-level deployment install pattern, and zddc/README.md for the HTTP server.
