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.

// Level-1 bootstrap. Fetches the tool from the deployment root (same
|
|
// origin) and document.write()s it in place. The target may be the real
|
|
// built tool HTML or a level-2 bootstrap that fetches from upstream.
|
|
//
|
|
// URL parameter ?v= selects a specific version or channel:
|
|
// ?v=0.0.4 (or v0.0.4) tries ../{{TOOL}}_v0.0.4.html locally
|
|
// ?v=alpha|beta|latest tries ../{{TOOL}}_<channel>.html locally
|
|
// (none) fetches ../{{TOOL}}.html (default)
|
|
//
|
|
// If the requested version is not staged locally, falls back to the
|
|
// root entry (../{{TOOL}}.html) — which, if it is a level-2 stub,
|
|
// forwards the param upstream to zddc.varasys.io. So ?v=0.0.4 works
|
|
// whether admins staged it locally OR a level-2 stub is at root.
|
|
//
|
|
// To pin this single tool to a fixed version permanently, replace the
|
|
// `fallback` constant below with an absolute URL like
|
|
// https://zddc.varasys.io/releases/{{TOOL}}_v0.0.4.html.
