# Zero Day Document Control (ZDDC)

**The Universal Distributed Filing Cabinet**

ZDDC is an information management convention plus a small set of single-file HTML tools. Every deliverable's filename encodes its tracking number, revision, status, and title; every transmittal folder is date-prefixed and self-describing. A plain shared folder becomes a fully searchable, auditable archive — no server, no database, no software required to read it.

The name "Zero Day Document Control" comes from the convention itself — adopt it on day zero of a project, with no setup time. The tools are *optional* interfaces around the structure; the structure works without them.

> **For end users**: <https://zddc.varasys.io/> introduces the project, links to all tool channels (stable / beta / alpha), and prints copy-paste shell snippets to install on a self-hosted deployment.

## Tools

| Tool | What it does |
|------|--------------|
| **Archive Browser** | Browse, search, and filter a project archive folder. Group by transmittal, export selections as ZIP. |
| **Transmittal Creator** | Self-contained HTML transmittal records with SHA-256 checksums and optional digital signatures. |
| **Document Classifier** | Spreadsheet-like bulk-renamer that copy/pastes with Excel and writes back to disk. |
| **Markdown Editor** | Browser-based markdown editor with YAML front matter, TOC, and direct local file access. |

Each tool is published in three channels (stable, beta, alpha) as static files served from <https://zddc.varasys.io/releases/>. **Local use:** download a `.html` file from `releases/` and open it in a browser. **Server use:** run `zddc-server` — the current-stable build of every tool is baked into the binary at compile time, so a fresh deployment Just Works with zero config. Tools auto-appear at folder-name-driven paths (archive everywhere; classifier in `Incoming`/`Working`/`Staging`; mdedit in `Working`; transmittal in `Staging`). Override per-directory by writing an `apps:` entry in any `.zddc` file (channel/version/URL/path). URL overrides are fetched once and cached in `<ZDDC_ROOT>/_app/`; drop a real `.html` file at any path to override entirely.

## File-naming convention

The full specification — filename format, tracking numbers, revision rules, status codes, folder naming, and the transmittal workflow — lives at <https://zddc.varasys.io/reference.html>.

## Build & develop

```bash
git clone https://codeberg.org/VARASYS/ZDDC.git && cd ZDDC

sh build.sh                              # build all tools (writes to dist/ only)
sh archive/build.sh                      # build one tool

sh archive/build.sh --release            # cut stable; auto-bumps patch from last tag
sh archive/build.sh --release 0.1.0      # explicit version
sh archive/build.sh --release alpha      # cut alpha (mutable channel, no tag)
sh archive/build.sh --release beta       # cut beta

npm install && npx playwright install chromium && npm test    # tests
./dev-server start                       # cache-busting HTTP on :8000
```

Authoritative build/release docs are in [`AGENTS.md`](AGENTS.md). Architecture notes (single-file rationale, JS module pattern, security model) are in [`ARCHITECTURE.md`](ARCHITECTURE.md). zddc-server (optional Go HTTP server with ACL and a virtual archive index) is in [`zddc/README.md`](zddc/README.md). Example Helm charts for deploying zddc-server (production + dev) are under [`helm/`](helm/).
