ZDDC d90975662f feat(zddc): Phase 4b — grid mode driven by cascade default_tool
The /incoming/ path regex in browse/js/grid.js was the second-most
visible client-side hardcode of the canonical convention. Migrating
it to the cascade:

  Header surface:
    X-ZDDC-Default-Tool: <name>   The cascade-resolved default tool
                                  for the listing's directory. Empty
                                  header = no default declared.

  Client wiring:
    loader.fetchServerChildren reads the header into
    state.scopeDefaultTool on every listing fetch (initial mount,
    rescope on dblclick, popstate). grid.classifierAvailableHere
    now returns scopeDefaultTool === 'classifier' instead of
    regex-matching the URL.

  Effect:
    Grid mode auto-activates wherever the cascade picks classifier
    as the default — currently archive/<party>/incoming per
    defaults.zddc.yaml. An operator who sets default_tool: classifier
    on a custom directory gets grid mode there too, no code change.
    An operator who removes the default at incoming sees grid mode
    stop auto-activating there.

  Bootstrap timing fix:
    The initial events.init() runs applyResolvedViewMode before the
    detection fetch completes, so state.scopeDefaultTool is empty
    at that point and grid never auto-activates on first paint.
    app.js bootstrap now re-applies the resolved view mode after
    autoDetectServerMode returns, so a fresh /incoming URL lands
    on grid mode immediately.

The /incoming/ regex is gone. Two client hardcodes remaining
(archive source heuristics, shared/nav stage strip) — Phase 4c/d.

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.
