Listing JSON gains a writable bool per file row, computed by running
the policy decider with ActionWrite against the parent-dir chain
(with the same admin-bypass branch the file API uses). Cost: one
extra decider call per file in the listing, sharing the parent
chain so the cascade walk is amortized.
Browse loader stores writable on every tree node. The markdown and
YAML editors read it and gate their canSave + initial mount:
- !writable markdown → Toast UI Viewer (rendered, no edit toolbar,
no caret). Banner above explains why save is disabled.
- !writable YAML → CodeMirror readOnly:'nocursor' (selection for
copy, no caret). Banner above explains why save is disabled.
Both editors gain autofocus:false so keyboard nav in the browse
tree doesn't divert into the editor — arrow keys keep moving through
files and folders without the caret jumping. User clicks (or tabs)
into the editor when they actually want to type.
.zddc files already route through preview-yaml's isZddcFile path;
bare .zddc (no ext) matches because that function checks the
literal name.

Major upgrade to the browse tool's UX, plus a few shared modules other
tools can adopt.
User-facing:
- Right-click context menu on tree rows AND empty pane space. Traditional
file-manager grouping (Open / Download / New / Rename-Delete / Copy /
Tree ops / View). Items stay visible but disabled when not applicable
so muscle memory carries. Generic shared/context-menu.js framework
supports normal items, toggles, submenus, separators, danger styling.
- YAML editor for .yaml / .yml / .zddc files (CodeMirror 5 vendored at
shared/vendor/codemirror-yaml.min.*). js-yaml lint on every change
for parse errors. For .zddc cascade files, an additional schema-aware
lint pass flags unknown keys, bad enum values, and wrong types.
- Per-row drag-drop upload using webkitGetAsEntry (folder uploads work
recursively). Per-row drop indicator; doc-level overlay still fires
for blank-space drops at drop_target scopes.
- New folder / New markdown file context-menu items (server mode).
Rename + Delete with native confirm() dialog. File-API helpers
removeNode / renameNode use the existing PUT/POST/DELETE endpoints.
- Hover info card with the row's full metadata (ZDDC fields + filesystem
info + path/URL). Interactive — mouse into it, drag-select text,
Ctrl/Cmd-C or right-click → Copy. 200ms grace before dismiss.
- Autofilter input at the top of the tree pane. Same grammar as
archive's column filters (zddc.filter.parse / matches). Filters
files; folders without matches collapse out. Non-matching folders
force-open visually when descendants match, without mutating the
user's actual expand state.
- Two-line ZDDC label: title-first, tracking/rev/status as monospace
meta below. Icon column anchors to the title line. Chevron is a
Lucide outline `chevron-right` SVG, rotated 90° on `.expanded`.
- File-type Lucide icon sprite (shared/icons.js — 16 outline glyphs,
~5 KB). PDF / Word / Spreadsheet / Slides / Image / Video / Audio /
CAD / Web / Config / Code / Archive get distinct icons; folders
tinted with --primary.
- Header wraps gracefully at narrow viewports (shared/base.css
flex-wrap + title min-width:0 ellipsis). Body becomes flex column
in browse so a wrapping header doesn't break #appMain height.
- Markdown editor opens in WYSIWYG mode by default. YAML front-matter
+ TOC sidebar reworked: flexbox layout (single visible resizer
between FM and TOC), both bodies overflow:auto for X+Y scrollbars.
- `?file=<path>` deep links open browse pre-positioned at a specific
file. Multi-segment paths walk into subdirectories on the way.
Auto-flips Show hidden when a segment is dot/underscore-prefixed.
- Refresh + show-hidden toggle preserve expansion / selection /
preview pinning. Path-keyed snapshot survives a re-fetched listing.
- "Add Local Directory" → "Use Local Directory" across the four tools
that have it (browse, archive, classifier, +transmittal comment).
