ZDDC 141fef88fb feat(browse): "Download (zip)" — pull the current directory's subtree as a zip 
A "⤓ Download (zip)" button in the browse toolbar (shown once a
directory is loaded) downloads the directory you're currently
viewing — and everything under it you're allowed to see — as a single
.zip. Navigate into a subfolder first to grab just that subtree.

- Server mode: an <a download> at "<currentPath>?zip=1" — zddc-server
  streams the ACL-filtered zip (see the previous commit), nothing held
  in the browser.
- Offline (file://) mode: new browse/js/download.js walks the picked
  folder with the FS-Access API in two passes — metadata first (so it
  can confirm() before loading >~2000 files / ~500 MB into memory),
  then bytes — bundles with the already-vendored JSZip, and triggers a
  blob download. Hidden entries (".":/"_"-prefixed) are skipped, the
  zip's top level is "<folderName>/…" so it unpacks tidily, and the
  status bar shows progress.

Wired in browse/js/events.js (button click + show/hide alongside the
refresh button); concatenated into browse/build.sh; ARCHITECTURE.md +
AGENTS.md note the ?zip=1 endpoint and the button.

browse — directory listing tool

Generic file browser for any directory. Designed to work with ZDDC archives but useful for any folder. Single-file HTML, no install.

How it's used

Two modes, auto-detected at page load:

  1. Online (zddc-server backed). When this HTML is served by zddc-server at a folder URL — which it is by default for any directory under ZDDC_ROOT that doesn't have an index.html — the JS queries the same URL with Accept: application/json to load the directory's listing and renders it as a sortable, filterable table.

  2. Local (FileSystemAccessAPI). Click "Select Directory" in the header to pick any folder on your computer. Works in Chromium-based browsers (Chrome, Edge, Brave, etc.). No server required; the directory is read directly from disk.

What it does

  • Lists files and folders with name, size, type (extension), and modified date.
  • Click a folder to expand inline. Children load lazily on first expand.
  • Click a column header to sort by that column. Click again to reverse.
  • Type in the filter to narrow to entries whose name contains the substring.
  • Click any file to open it in a new tab — for server-backed pages, this routes through zddc-server's normal handler (so an .archive redirect, an apps cascade override, etc. all work as expected).

Design notes

  • No ZDDC-specific filtering. This tool is intentionally domain-agnostic. The companion archive tool layers ZDDC parsing (project / status / revision filters, tracking-number resolution) on top of the same listing API. Use archive when you want ZDDC semantics; use browse when you just want to see what's in a folder.
  • Default at directory URLs. zddc-server's directory.go serves the embedded browse.html bytes for any directory request with Accept: text/html and no index.html present. This means a user navigating to any folder under ZDDC_ROOT gets a usable browser without anyone having to drop a file into the archive.
  • Apps cascade override. Like every other ZDDC tool, the served browse.html can be overridden per-folder via a .zddc apps: entry. The default is the embedded copy from the binary; operators can pin a specific version or URL if they want.
