Two related routing fixes:
1. /<project>/archive/<party>/mdl[/] now follows the slash/no-slash
convention uniformly with the rest of the system:
- mdl (no slash) → tables app (default tool for mdl/)
- mdl/ (slash) → browse (ServeDirectory empty-listing fallback)
Previously the slash form auto-redirected to mdl/table.html, which
forced the user into the table view from any party-folder click and
produced a confusing "Unrecognized table URL" error when the
redirect race-conditioned. tableRowsRedirect now only redirects
when a real on-disk table.yaml exists; the default-MDL virtual case
stays in browse via the convention.
New zddc.IsArchivePartyMdlDir helper recognises the canonical
<project>/archive/<party>/mdl pattern at depth 4 (relative path).
fs.ListDirectory uses it to return [] for the missing-on-disk case
so browse renders the empty workspace cleanly. Test updated
(TestServeDirectoryRedirectsDefaultMdl → TestServeDirectoryDefaultMdlNoRedirect).
2. <dir>/.zddc URLs now work at every directory depth.
The dispatcher previously 404'd anything beginning with a dot
(except /.archive and /<dir>/.zddc.html). New IsZddcFileRequest +
ServeZddcFile handlers carve out the raw .zddc leaf so an operator
can navigate to /Project-1/archive/PartyA/mdl/.zddc and inspect
the rules effective at that depth.
Semantics:
- Method: GET / HEAD only. Writes go through the existing admin-
gated form at <dir>/.zddc.html (unchanged).
- ACL: parent directory's read permission gates access; 404
(not 403) is returned to non-readers so existence isn't leaked.
- On disk: file bytes served verbatim with
Content-Type: application/yaml and X-ZDDC-Source: file:<rel>.
- Virtual: when no file exists at this level, a synthetic
placeholder body is returned with a YAML-comment cascade
summary so the reader sees exactly what rules apply here from
ancestors. X-ZDDC-Source: virtual:zddc distinguishes it.
The virtual body parses as valid YAML (`{}` after the comments) so
downstream tooling that consumes the URL isn't confused.

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/.
