grid.js was classifier-only; make it embed ANY embeddable full-page tool the
cascade resolves as default_tool — classifier (incoming/), transmittal
(staging/), archive (the index) — as an iframe scoped to the current dir
(<dir>/<tool>.html). This is the browse-as-shell bridge from the ADR: browse
stays the top-level app and the heavy tools open in-pane (the gridView), so
navigating to staging/ or archive/ inside browse shows transmittal/archive
without leaving the shell, with ?view=browse falling back to the folder
listing (and the standalone tools still served directly at the no-slash URL).
EMBEDDABLE = {classifier, transmittal, archive}; tables/forms embed in the
preview pane instead, landing/browse don't self-embed. resolveViewMode keys
off grid.availableHere() (now generic). Validated in a containerized browser:
each dir embeds its tool, ?view=browse overrides to the listing.

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.

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).

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).
