Drops the `download` attribute and adds `target="_blank"`. Click now
opens the conversion URL in a new tab; the server's
Content-Disposition: inline routes each format to a sensible
behavior in that tab:
• HTML → renders as a web page
• PDF → opens in the browser's PDF viewer
• DOCX → auto-downloads (browser can't render Office Open XML),
tab is transient
Right-click → "Save Link As" still works for explicit save-to-disk.
Side benefit for debugging: when the conversion endpoint returns
422 or 503, the response body appears as a plain-text page in the
new tab, which is easier to triage than a transient toast.
Right-click → "Copy Link Address" / "Open in New Tab" / "Save Link
As" now work natively, so users can share the conversion URL or pick
their own download path. The buttons are styled <a href> elements
instead of <button>, with the `download` attribute set to the
expected filename (foo.docx etc.) so a plain click still downloads.
Click handler simplifies a lot: on clean buffer, the handler returns
immediately and the browser handles the navigation. On dirty buffer,
the handler intercepts, auto-saves, then re-fires the click — which
re-enters the handler with dirty=false and falls through to the
native navigation. No more JS fetch + blob + objectURL plumbing for
the common path.
Side effect: if the server returns 422 or 503, the browser shows the
response body in the target tab. That's less polished than the
previous toast, but it's also a more direct view of what the server
actually said. The toast path stays in shared/zddc-source.js's
downloadConverted helper for tools that prefer the JS-driven flow.
Two improvements to browse's preview-markdown plugin so it can replace
the standalone mdedit tool:
1. **YAML front-matter editing.** The FM pane above the outline used to
render a read-only <dl> of parsed keys — sparse and unusable when
the file had no envelope yet. It's now a dedicated <textarea> that's
always present. On load, parseFrontMatter() splits the `---\n…\n---`
envelope off the body: the body feeds Toast UI Editor, the envelope
feeds the textarea. On save, assembleContent() recombines them.
Dirty tracking covers both halves via a SHA-256 of the assembled
bytes. The shell mirrors mdedit's old layout (FM textarea top,
outline below) but the FM pane is now always functional, eliminating
the "empty pane over the TOC" problem.
2. **Download as DOCX / HTML / PDF.** When the file handle is HTTP-
backed (server mode) and the file is a .md, three buttons appear in
the info header next to Save. Clicking one fetches the server's
?convert=<fmt> endpoint and triggers a browser download with a
clean filename (foo.md → foo.docx). Auto-saves the buffer first if
dirty so the converted bytes reflect what's on screen.
Helper at window.zddc.source.downloadConverted (shared/zddc-source.js)
so other tools — archive, transmittal — can reuse the same flow later.
Friendly error messages map HTTP 503 / 422 / 504 to actionable toasts.
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.

New shared/zip-source.js: a ZipDirectoryHandle / ZipFileHandle pair
that exposes a JSZip instance behind the File-System-Access surface
(values/entries/keys, getDirectoryHandle/getFileHandle, getFile) —
read-only, with a zip-slip guard. Mirrors shared/zddc-source.js's
HTTP polyfill. Wired into archive's and browse's build.sh (both
already bundle JSZip).
archive: a .zip whose name minus ".zip" parses as a transmittal-folder
name is now scanned as that transmittal folder. Offline, the zip is
opened in the browser (ZipDirectoryHandle) and its members enumerated
exactly like an uncompressed folder's files — table/export/hash paths
are unchanged (they go through file.handle.getFile()). Online, the
scanner recurses into the server's "<…>.zip/" virtual-directory
listing, so members come back as "<…>.zip/<member>" URLs the server
extracts on demand — no whole-zip download.
browse: the offline (file://) zip path is migrated onto the shared
adapter — expanding a .zip now opens it as a ZipDirectoryHandle and
its members become ordinary dir/file nodes handled by the normal
fetchFsChildren path (nested zips fall out by recursion). The bespoke
flat-entry walker (loadZipChildren / setZipDirChildren / zipEntries /
zipParentId / zipPath / _zipSyntheticDir) is gone — one zip
implementation repo-wide. Markdown members inside a zip are flagged
read-only (the ZipFileHandle refuses createWritable; server "<…>.zip/"
URLs 405 on PUT).

When browse runs against zddc-server, expanding a top-level .zip now
fetches "<…>.zip/" as a normal directory listing (the server extracts
members on demand) instead of downloading the entire archive and
parsing it with JSZip in the browser. Members open/preview via their
real server URLs like any file. Nested zips (a .zip inside a .zip) and
FS-API (offline) mode keep the existing JSZip path; offline gets
migrated to a shared adapter in the next change.

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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The last hardcoded client-side knowledge of the canonical convention
was the upload-zone regex in browse:
var UPLOAD_SCOPES = /\/(working|staging|incoming)(\/|$)/i;
Now declared in the cascade:
Schema:
drop_target: true|false leaf-only; describes THIS dir
(not propagated to descendants)
Lookup:
zddc.DropTargetAt(root, dir) bool
Surfaced to clients:
Directory listings carry an X-ZDDC-Drop-Target: true response
header when the cascade declares this leaf as an upload zone.
No header = no drop target.
Defaults populated:
working / working/* / staging / archive/<party>/incoming
all carry drop_target: true. Operators can extend (e.g. drop
files on archive/<party>/received via override) or disable
(e.g. drop_target: false at a specific staging subtree) without
touching code.
Browse migration:
loader.fetchServerChildren reads the response header and stamps
state.scopeDropTarget on every listing fetch. upload.js's
currentScopeAllows now reads that flag instead of regex-
matching the URL. Initial value is false in init.js so a
listing failure (offline / server doesn't emit the header)
safely defaults to "no drop zone".
Phase 4a closes the most visible asymmetry between server-side and
client-side cascade knowledge. The remaining client hardcodes
(browse grid-mode regex, archive source heuristics, shared/nav
stage strip) follow the same pattern when needed — Phase 4b/c/d.

Drop files anywhere on a browse page; if the current scope is inside
a working/, staging/, or incoming/ subtree the files are PUT to the
current directory via the existing file API. Per-file ACL is enforced
server-side (authorizeAction); a 403 surfaces as a per-file error
toast and the rest of the batch proceeds.
UX:
- dragenter → semi-transparent overlay with a dashed-border panel
showing the destination path. Hides immediately on dragleave or
drop.
- drop → "Uploading N files…" toast, then per-file failure toasts
inline, then a summary toast (success / partial / all-failed).
- listing auto-refreshes after the batch so new files appear in
the tree without a manual reload.
Scope:
- upload-eligible paths are matched by /\/(working|staging|incoming)
(\/|$)/i — same convention as the new grid-mode URL token.
- 256 MiB per-file cap (UPLOAD_MAX_BYTES) since browse's single-
body PUT loads the file as a Blob in the tab; larger uploads
should use a dedicated client.
- Outside the upload-eligible set the overlay never appears; drops
are silently ignored (drag effect = none).
Sequential uploads keep progress predictable; parallel batching can
land later if needed. The module hooks document-level dragenter/leave
/over/drop so it works regardless of which pane the user drags over.

User feedback: the Grid toggle button was on every page and showed an
explanatory empty state when classifier wasn't available — adding UI
to explain why UI didn't work. Cleaner approach: drop the button,
make the URL the source of truth, and default grid mode automatically
inside the only context where it's meaningful.
Behavior:
- Inside any incoming/ path (case-insensitive segment match):
→ grid mode by default
- Everywhere else:
→ browse mode
- Explicit overrides via query string:
?view=grid forces grid (only honored where classifier is
available; otherwise falls back to browse)
?view=browse forces browse (always)
UI changes:
- The Browse/Grid pill toggle is gone.
- grid.js drops both empty-state messages; outside an incoming/
path it just does nothing.
- events.js owns resolveViewMode() / applyResolvedViewMode(),
called on initial mount and after every client-side rescope
(dblclick + popstate).

User report: project root listings showed both "Archive" (PascalCase on
disk) and "archive (empty)" (lowercase virtual) — confusing duplicates.
This sweep:
1. Test fixture migrated to lowercase canonical folder names.
tests/data/test-archive.sh now creates archive/, received/, issued/
on disk. Three projects also get human-friendly .zddc titles
("Wabash Industrial Refit — Phase 1", etc.), and Project-3 carries
a display: override demonstrating the new map. Party names
(PartyA/B/C) stay unchanged — non-canonical.
2. New .zddc display: schema. Maps a child entry's on-disk name to a
human-friendly label. The on-disk name stays canonical (lowercase
for project-root folders); only the rendered label changes. Match
is case-insensitive. Example:
display:
archive: "Records"
working: "In-Progress"
No upward cascade — a parent .zddc doesn't relabel grand-children;
each directory sets display: on its own children.
3. listing.FileInfo gets a DisplayName field. fs.ListDirectory reads
the directory's .zddc display map and stamps DisplayName per entry.
The field is omitempty so listings without overrides stay
byte-identical to before.
4. Virtual canonical project-root folders (archive/working/staging/
reviewing) are now emitted by zddc-server (fs.ListDirectory) at any
project root where the on-disk variant is absent in any case. This
replaces the client-side injection in browse and lets the display:
map apply to virtual entries the same way it applies to real ones.
Browse drops its withVirtualCanonicals helper; the loader carries
display_name through from the server's listing.
5. Archive app project picker dropdown shows the .zddc title of each
project (sourced from ProjectInfo.Title in the server's project
list), falling back to the folder name when no title is set. When
they differ, the folder name is rendered in muted mono after the
title for traceability. data-name still carries the canonical
folder name so URL state stays stable.

Four user-reported items:
1. landing: remove the standalone-tool strip from the site picker.
Per user, it was awkward — links pointing at zddc.varasys.io
releases from inside a deployment is a layering confusion. The
nav.tool-strip block in landing/template.html and its CSS are
gone.
2. zddc-server: route /Project/archive/<party>/mdl[/] to the tables
app for the virtual-MDL case where the on-disk folder doesn't
exist yet. Previously fell through to 404 because the dispatcher
only routed virtual mdl/ via the IsDir branch — the IsNotExist
branch was missing the equivalent check. Now both shapes (with
and without trailing slash) hit RecognizeTableRequest's default-
MDL fallback and ServeTable serves the embedded tables.html.
3. browse: re-layout the markdown editor to mirror mdedit's layout.
Was: sidebar on right with TOC top + front-matter bottom.
Now: sidebar on LEFT with YAML front matter top + Outline bottom,
content on RIGHT with an informational header (file title +
save controls + status + source) above the Toast UI editor.
New horizontal resizer between the front-matter and outline
sections inside the sidebar (drag the row boundary; arrow keys
step by 24 px). Browse test selectors updated.
4. zddc-server reviewing aggregator: extend to depth ≥ 2 so the
user can preview files inside virtual reviewing/<tracking>/
received/ and staged/ folders. IsReviewingPath now returns a
sidePath ("received[/rest]" or "staged[/rest]"); ServeReviewing's
depth-2 branch proxies the underlying real folder's listing,
emitting folder entries with virtual reviewing/ URLs (so
navigation stays in the aggregator) and file entries with
canonical archive/ or staging/ URLs (so byte fetches resolve
directly). ACL is enforced against the real path; depth-1
received/ + staged/ URLs are now virtual too (was canonical),
so the user smoothly descends into the depth-2 listing.
Tests updated for the new IsReviewingPath signature and the depth-1
URL shape.

Hard navigation to /<path>/ lets zddc-server's auto-serve kick in for
canonical folders — /archive/ swaps in the archive tool, /staging/ the
transmittal tool, etc. — so double-clicking a canonical folder from
inside browse silently swapped the user out of browse, contrary to
what they expected.
Fix: client-side rescope. navigateIntoFolder() now fetches the new
directory listing via the loader, calls tree.setRoot() with virtual
canonicals re-applied, and pushes the new URL via history.pushState.
The page never reloads. A subsequent reload still works (browse loads
itself at the new URL since trailing-slash → ServeDirectory → embedded
browse SPA).
Side effects:
- augmentRoot (the canonical-folder injection helper) exposed via
window.app.modules so events.js can re-apply it on rescope.
- popstate handler: back/forward in the browser triggers the same
rescope path with the historic URL.
- Selection + preview reset on rescope; the previous file's preview
isn't carried into the new scope.

The previous nested-flexbox layout produced indeterminate heights
inside the Toast UI editor host and made the TOC pane width fragile —
visually the editor and outline weren't laying out reliably. This
swaps the whole shell to CSS Grid, which gives every cell a definite
size.
Layout:
┌──────────────────────────────────────────────────────────────┐
│ toolbar (Save | ● modified | status | source) │
├─────────────────────────────────────┬────────────────────────┤
│ │ Outline │
│ Toast UI Editor │ • Heading 1 │
│ (md / wysiwyg / preview) │ • Subheading │
│ ├────────────────────────┤
│ │ Front matter │
│ │ title: … rev: … │
└─────────────────────────────────────┴────────────────────────┘
Notes:
- The shell mounts as a single child of #previewBody (not by
re-classing previewBody itself), so the outer flex layout that
fills the preview pane is preserved.
- Sidebar is its own grid (outline 1fr + front-matter auto/max 40%),
each section independently scrollable.
- Resizer is a 6 px element on the grid column boundary; drag
updates grid-template-columns. Keyboard left/right adjust by 24 px.
Width persists across mounts (lastTocWidth) within a session.
- parseHeadings now skips front-matter envelope + fenced code so a
"##" inside ```bash``` doesn't show up as an outline entry.
- scrollEditorToHeading uses findScrollParent + scrollTo({behavior:
'smooth'}) so jumps feel less jarring.
- Class names follow BEM: .md-shell__*, .md-side__*, .md-toc__*,
.md-fm__*. Tests updated to the new selectors.

#5 — Double-click on a folder no longer toggles collapse.
Root cause: the single-click handler called tree.render() immediately,
which replaced the clicked row element. The browser's double-click
detection requires the second click to land on the SAME target as the
first, so dblclick never fired for folders.
Fix: defer the single-click toggle by 220ms. A pending dblclick within
the window cancels the toggle and runs navigateIntoFolder instead.
Modifier-clicks (shift/alt for recursive) and ZIP expands skip the
deferral — they're never followed by a dblclick navigation.
#3 — Browse at /<project>/ now always shows the four canonical
folders (archive, working, staging, reviewing) even when they don't
yet exist on disk. Each missing folder is synthesized client-side as
a "virtual" row: muted icon + label + "(empty)" hint, double-clickable
to navigate. zddc-server already serves an empty listing for these
paths (commit 3fc3717), so navigation into a virtual folder works
without 404 and the user lands in a sensible empty workspace.

Markdown preview pane now surfaces YAML front-matter above the TOC as a
key/value list (definition list), so engineering documents with header
metadata (title, revision, status, etc.) show their identity at a glance
without opening the file in mdedit. Front-matter parsing handles both
scalar and array values; arrays render as comma-joined.
TOC pane is now resizable (4px col-resize handle on its left edge);
preserves the user's chosen width across re-renders inside a single
session.
mdedit welcome banner moved inside #welcome-screen so the "browse opens
md in this same editor" callout only shows when no file is open — it
was previously visible in every state which was noisy.
archive.spec.js: wait for #filePreviewToggle to be attached before
clicking, fixing a Playwright flake where the preview button hadn't
mounted yet.

The tree's underlying setSort API was carried forward from the old
table-with-clickable-headers UI but had no widget driving it after
the layout reshape. Adds an explicit dropdown in the toolbar:
Sort: [Name (A→Z) ▾]
[Name (Z→A) ]
[Modified (new→old) ]
[Modified (old→new) ]
[Size (large→small) ]
[Size (small→large) ]
[Type (A→Z) ]
Implementation:
- new tree.setSortExplicit(key, dir) — sets both axes in one call
(the existing tree.setSort toggles direction on repeat-clicks,
which is the right semantics for column-header clicks but wrong
for an explicit dropdown).
- events.js parses the dropdown value as "<key>:<asc|desc>" and
calls setSortExplicit. The dropdown is initialised to reflect
the current sort state on mount.

Completes the markdown plugin's deferred v2 items:
1. TOC pane
A third pane to the right of the Toast UI editor lists every heading
in the current document, hierarchically indented by level. Click an
item → editor scrolls to that heading (markdown-mode uses
setSelection + preview scroll; WYSIWYG mode uses DOM text matching;
the target heading flashes briefly via primary-light background).
The TOC re-renders on every editor change (debounced 250ms) so it
stays in sync with edits.
Heading parser supports ATX-style `^#{1,6}\s+` lines, strips inline
markdown emphasis/code/links/strike from the displayed label.
Empty file → "Empty file." Headingless file → "No headings."
2. FS-API writes
Saves now route to whichever source the file came from:
- node.handle + createWritable available → FileSystemWritableFileStream
(local folder picker). The user's chosen file gets overwritten
via the browser's File System Access API.
- node.url + server source → PUT to the server URL (as before).
- zip-virtual file → save disabled (no writable stream from JSZip).
- Anything else → save disabled with a tooltip.
Save status surfaces via the existing toolbar (`Saved 10:42:18`) AND
a shared toast notification ("Saved readme.md" / "Save failed: …")
so the success/failure is visible regardless of whether the user is
looking at the toolbar.
Source-hint chip on the toolbar shows "local" / "server" /
"read-only (inside zip)" so the user knows which write path is
active before they make changes.
CSS additions in browse/css/tree.css for .md-toolbar, .md-split,
.md-editor-host, .md-toc-pane, .toc-list, and the .toc-level-1..6
indentation rules.
A new Playwright test exercises the markdown plugin end-to-end:
mounts the editor on a .md click, asserts the three DOM regions are
visible, verifies the TOC contains the three expected headings from
the test fixture's markdown content, and confirms the source hint
reads "local" for FS-API mode.

Reshape browse from "tree-as-table with popup preview" into a unified
file-experience tool with three layered behaviors:
Phase A — Two-pane shell
Phase B — Markdown plugin (Toast UI inline)
Phase C — Grid mode (classifier workflow)
Phase D — Deprecation banners on standalone classifier + mdedit
= Phase A: two-pane shell + lightweight preview plugins =
Browse's table view becomes a tree-pane on the left + preview-pane on
the right with a draggable resizer. Click a folder → expand inline.
Click a file → render in the right pane. The previous popup window
becomes an explicit "⤴ Pop out" button in the right-pane header for
users with a second monitor.
Preview rendering reuses shared/preview-lib.js (PDF iframe, image
<img>, TIFF, ZIP listing, text <pre>). Unknown types show a download
link. browse/js/preview.js refactored into renderInline (default) +
renderInPopup (Pop out button); both share the same plugin
dispatch logic.
Filter rows were already removed earlier this session. Sort columns
likewise — the tree is alphabetical by default; the underlying
setSort API still exists for future re-introduction.
= Phase B: markdown plugin =
New browse/js/preview-markdown.js: when a .md or .markdown file is
clicked, the right pane mounts a Toast UI editor (initial-value =
file contents) with a small toolbar containing Save + dirty indicator
+ status text. Save sends PUT through the file API for server-mode
files; non-server sources are read-only for now (deferred to a
follow-up that wires zddc-source.js writes too). Ctrl+S / Cmd+S
inside the editor saves.
Toast UI Editor (~700 KB JS + ~160 KB CSS) was previously bundled
only in mdedit/vendor/. Moved to shared/vendor/ so browse and mdedit
both pull from one location.
= Phase C: grid mode =
View-mode toggle [Browse | Grid] in the toolbar. Grid mode loads the
classifier tool as an iframe scoped to the current directory (server
mode at working/staging/incoming locations) — classifier's full
bulk-rename workflow without leaving browse. v1 implementation; a
future iteration could bundle classifier's modules directly into
browse for tighter integration. Hostile cases (file:// origin, paths
outside working/staging/incoming) show a friendly explanation
instead of a blank iframe.
new browse/js/grid.js handles the activation logic.
= Phase D: deprecation banners =
mdedit and classifier standalones gain a "this tool is being absorbed
into Browse" advisory banner. Both standalones remain fully
functional and continue to ship — they're useful for offline single-
file editing and air-gapped environments. The banner just points
users toward the unified browse experience.
= Files =
+ browse/js/preview-markdown.js (markdown plugin)
+ browse/js/grid.js (grid-mode plugin)
M browse/template.html (two-pane layout, view toggle, banners)
M browse/css/tree.css (two-pane CSS, replaces table styles)
M browse/js/init.js (state additions: selectedId, viewMode)
M browse/js/tree.js (rowHtml: <tr>+<td> → <div>)
M browse/js/preview.js (renderInline / renderInPopup split)
M browse/js/events.js (toggle wiring, resizer, click handlers
adapted from <table> to <div>)
M browse/build.sh (Toast UI vendor + new modules)
R mdedit/vendor/toastui-* → shared/vendor/ (one bundle, two tools)
M mdedit/build.sh (paths)
M mdedit/template.html (deprecation banner)
M classifier/template.html (deprecation banner)
M tests/browse.spec.js (selectors updated for new layout +
new "click file → preview" test)
Bundle sizes after this commit:
browse: ~1020 KB (was ~290 KB; added Toast UI ~700 KB)
classifier: ~1470 KB (unchanged from prior baseline)
mdedit: ~2140 KB (unchanged; vendor location moved but not added)
What's deferred:
- TOC + front-matter pane in browse's markdown plugin (mdedit has
these; browse v1 uses just the editor).
- FS-API writes from browse's markdown plugin (server PUT works).
- Classifier modules bundled directly into browse (v1 uses iframe).
- Sort UI in the new tree (model still supports it; no widget yet).

The two filter rows (📄 file/ext + 📁 folder) didn't really earn their
header real estate. Browse is for navigating directory structure;
ad-hoc filters across a tree of mixed file types and depths weren't
the right affordance, and the visual weight competed with the column
headers and the breadcrumb. Removed entirely:
- template.html: dropped both <tr class="filter-row"> rows in <thead>,
the related "Filter rows" help section, and the empty-state copy
that mentioned the 📄/📁 rows.
- init.js: dropped state.filters (file/folder/ext slots).
- events.js: dropped the .column-filter[data-filter] input wiring.
- tree.js: dropped recomputeVisibility() and the n.visible plumbing
in visibleIds() and updateCount(). Render is now a straight depth-
first walk over expanded subtrees; the count is just total rows.
setFilter is removed from the public API.
- css/tree.css: dropped .filter-row*, .filter-row__icon, and the
browse-local .column-filter rules (.column-filter is also defined
in shared/base.css for tools that still use it; that stays).
No test changes — tests/browse.spec.js never exercised filters.

Expanding a folder that returns 404 used to throw "HTTP 404 fetching
…" through statusError, surfacing it as a red error toast. From the
user's POV, a missing or empty directory shouldn't be presented as a
load failure — empty IS the legitimate state.
fetchServerChildren now returns [] on 404; other non-2xx still throw.
Other failure modes (transport error, 500, malformed JSON) continue
to surface as before.
Server-side, zddc-server already returns 200 + [] for canonical
project folders that don't exist on disk (the prior commit). This
client fix covers the residual cases:
- non-canonical paths that don't exist (deleted between listing
and expand; race with concurrent writers)
- non-zddc-server backends (Caddy file_server, plain nginx) where
we can't change the 404 behavior
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Single-click still expands the folder inline; double-click swaps the
view's root onto the folder. In server mode it loads the folder's URL
(zddc-server returns a fresh browse instance scoped there); in FS-API
mode it re-roots state.rootHandle onto the folder's handle and re-
enumerates. Files and zips are unchanged — files have a single-click
preview, zips have inline JSZip expansion.
Help panel updated to document the new behavior.

- Vendor JSZip locally (shared/vendor/jszip.min.js) and bundle into
the browse build instead of CDN-loading. Eliminates the failure
mode where ZIP rows can't expand because the CDN script doesn't
load (CSP, network, etc.). Tool now works fully offline.
- Replace the toolbar filter input + ext multi-select with two
spreadsheet-style auto-filter rows in <thead>:
- 📄 row: file-name filter + extension filter
- 📁 row: folder-name filter
Each input uses shared/zddc-filter syntax (substring/!negate/
^startsWith/$endsWith/regex/| or/space and).
- New visibility model with ancestor-of-match awareness:
- file matches keep their ancestor folders visible (path-to-hit)
- folder match keeps its descendants visible
- filters compose (file ∧ folder ∧ ext) so combinations narrow
Computed model-side; render walks only visible nodes.
- Replace 🏠 emoji breadcrumb-root with an inline outline-stroke SVG
that tints with currentColor.
Bundles Phase 2 polish + the user-requested header/breadcrumb work:
- Breadcrumbs replacing the plain currentPath span. Server mode
renders linkified ancestor segments (each <a> navigates to that
directory; the browser fetches browse.html, the new instance
auto-loads the listing). FS-API mode renders the rootHandle name
as a non-link (no ancestor handles to navigate). Both prefix the
path with a 🏠 root icon. Trailing slash + bold-current segment
match common file-explorer conventions.
- Subdued 'Select Directory' button in server mode. Once browse is
serving a real directory listing, the local-folder switcher is
available but visually quiet (btn--subtle: transparent, muted
color). FS-API mode keeps the primary styling (it's how the user
got there). New btn--subtle CSS class added to browse's tree.css.
A refresh button (⟳) appears next to it in both modes; clicking
it re-fetches the current root listing.
- Header consistency: browse now matches archive's header layout
(refresh + help buttons in addition to theme on the right). Help
is a placeholder for future help dialog wiring.
- File preview popup. Click a file row → opens a popup window with
the file rendered. Plain types (PDF, HTML, image) load in
iframes; TIFF + ZIP listings via shared/preview-lib.js's
renderTiff / renderZipListing helpers; text via <pre>; unknown
types → 'click Download' placeholder. Modifier-click (ctrl/cmd/
shift) and middle-click still open the file in a new tab via the
underlying <a target=_blank>. Single popup window is reused
across multiple file clicks (matches archive's UX).
- ZIP inline expansion. .zip files have a chevron and act like
folders in the tree. First expand fetches the zip bytes
(server URL or FS handle or parent-zip read), parses with JSZip
(auto-loaded from CDN), and synthesizes the entry tree. Nested
directories within the zip lazy-expand on demand by re-walking
the cached entry list at the right path prefix. Click on a
zip-entry file opens the preview popup with bytes read from
JSZip. Recursive expand-all skips zip archives by design — they
can be very large, and explicit click-to-expand is safer.
- Extension multi-select filter. Toolbar now has a <select
multiple> populated with extensions present in the current
view. Filter is OR-of-selected; combined with the name filter
it's AND-of-both. Folders pass through (so expanding a folder
whose name doesn't match the ext filter still shows its file
children that do match).
Three issues from initial v0.0.12 dev/prod testing:
1. Online listings empty.
directory.go was missing Vary: Accept on its responses, so
browser/CDN cached the HTML response (the embedded browse.html)
and served it again when browse's JS later fetched the same URL
with Accept: application/json. JSON parse failed, autoDetect
returned null, empty state showed. Adds Vary: Accept on both
branches and changes browse.html cache-control to no-cache so
deployed updates land immediately.
2. Top-level folder rows tall, shrink as subtree expands.
The .browse-table had flex:1 in a flex column. <table> in flex
doesn't reliably distribute height across rows — with few rows,
each row stretched. Wrap the table in a div with overflow:auto
and drop flex:1 from the table itself.
3. Recursive expand/collapse.
Shift-click (or alt-click) on a folder now expand-all or
collapse-all its subtree. Plain click still toggles just that
folder. Implementation: tree.expandSubtree() walks BFS, loading
each level's children in parallel, re-rendering between levels
so the user sees progress. tree.collapseSubtree() recursively
marks the subtree collapsed (children stay loaded for instant
re-expand).
A new HTML tool — browse — that lists the contents of any directory.
Designed for ZDDC archives but no ZDDC-specific filtering; just a
straight folder browser with expand/collapse, sort, and name filter.
Modes (auto-detected at page load):
- Online: when served by zddc-server at a folder URL, queries
the same URL with Accept: application/json to load the listing
and renders it. Auto-served as the default at any directory
under ZDDC_ROOT without an index.html (replacing the previous
minimal-HTML stub from directory.go).
- Local: 'Select Directory' button uses FileSystemAccessAPI to
pick any folder on disk; works in Chromium-based browsers.
Features (Phase 1 — what's in this commit):
- Tree view with lazy-loaded folders (children fetched on first
expand).
- Sort by name / size / extension / date (column header click).
- Filter by name substring (toolbar input).
- File click opens in a new tab — for server-backed pages,
routes through zddc-server's normal handler so .archive
redirects + apps cascade overrides + ACL all apply.
Phase 2 deferred:
- ZIP files inline expansion (treat archive entries as virtual
children).
- File preview popup (reuse shared/preview-lib.js).
- Extension multi-select filter.
Wiring:
- browse/ added to top-level ./build's per-tool list, embed
block, versions.txt, and the lockstep release commit + tag set.
All seven tools (archive, transmittal, classifier, mdedit,
landing, form, browse) advance together on stable cuts.
- shared/build-lib.sh: browse added to ZDDC_RELEASE_TOOLS and
verify_channel_links's per-tool loop.
- zddc/internal/apps/embed.go: //go:embed browse.html +
EmbeddedBytes("browse") case.
- zddc/internal/apps/availability.go: browse available at every
directory (same as archive).
- zddc/internal/apps/handler.go: MatchAppHTML routes
/<dir>/browse.html → 'browse'.
- zddc/internal/handler/directory.go: when a directory request
arrives with Accept: text/html and no index.html exists,
serve the embedded browse.html bytes (with a JSON-fallback
if the embedded slot is empty during bootstrap).
