transmittal/css/utilities.css hand-rolled a Tailwind-style utility
subset against hardcoded grayscale (#fff, #f9fafb, #d1d5db etc.)
tuned for light mode. Dark mode then needed a 17-line block of
!important rules in transmittal/css/base.css to swing each utility
class's background/text/border colors. That block was the worst
concentration of !important in the repo.
Tokenize the grayscale classes against shared CSS custom properties
(var(--bg), var(--bg-secondary), var(--text), var(--text-muted),
var(--border)) so the cascade picks up dark mode automatically:
.bg-white, .bg-gray-50, .bg-gray-100 → var(--bg) / var(--bg-secondary)
.text-gray-{400..700,900} → var(--text-muted) / var(--text)
.border, .border-{b,t}, .border-gray-* → var(--border)
.hover:bg-gray-{50,100} → var(--bg-hover)
.focus:bg-white:focus → var(--bg)
Named-color text classes (.text-blue-600 / -green-600 / -red-600)
stay hardcoded — they encode link / success / danger semantics that
should not theme-shift.
The .table-filter-input dark-mode block also went — it was unused
(no element references it; .column-filter from shared is what gets
applied to the actual filter inputs).
!important count in transmittal's non-print CSS dropped from ~32 to
~12. The 6 transmittal Playwright specs still pass.
Verification needed: visually inspect transmittal in both light and
dark mode and flag any color regression. The token mapping is
mechanical but the live rendered output is the only proof.

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. |
| Form Renderer | Schema-driven *.form.yaml editor — every form spec auto-mounts an editable form at <name>.form.html. |
| Tables | Sortable, filterable, in-place-editable grid view over a directory of YAML rows; click a row → edit in the form renderer. Auto-mounts on any directory containing a table.yaml. |
| Browse | File-tree navigator with previews; the everywhere-available companion to the Archive Browser when you want plain folder navigation rather than tracking-number aggregation. |
| Landing | The project picker served at the deployment root of a zddc-server. |
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
git clone https://codeberg.org/VARASYS/ZDDC.git && cd ZDDC
./build # dev build of every tool (writes to dist/ only)
sh archive/build.sh # iterate on one HTML tool
./build alpha # lockstep alpha cut for all nine artifacts
./build beta # lockstep beta cut
./build release # lockstep stable, coordinated next version
./build release 1.2.0 # lockstep stable at explicit version
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. Architecture notes (single-file rationale, JS module pattern, security model) are in ARCHITECTURE.md. zddc-server (optional Go HTTP server with ACL and a virtual archive index) is in zddc/README.md. Example Helm charts for deploying zddc-server (production + dev) are under helm/.
