ZDDC 4dfbc44d45 feat(elevation): on-page admin-mode toggle, ephemeral per-page 
Admins opt into admin powers via an on-page switch instead of only
?admin=true. The toggle renders ONLY for users the server reports
can_elevate, reusing each tool's existing header placeholder (or
creating one) and floating it bottom-right via fixed positioning.

Admin mode is now EPHEMERAL — scoped to the page you armed it on:
  - the zddc-elevate cookie is session-scoped (drops the 30-min Max-Age)
  - pagehide clears it, so navigating away / closing drops admin

Because a reload would race the pagehide-clear, every arm/drop path
(toggle, ?admin= URL, banner "Drop admin") now applies IN PLACE and
emits a `zddc:elevationchange` event. browse listens for it and
re-fetches the listing (server-computed verbs) + re-renders the open
preview, so editor affordances reflect the new elevation without a
manual reload.

Validated end-to-end in a containerized Chromium (Playwright over CDP)
against a local zddc-server: the toggle renders for can_elevate, arming
sets the session cookie + armed chrome, "Drop admin" and navigate-away
both clear it, and ?admin=true still arms via the same funnel.

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.
