Removes every runtime CDN load. The "ship the record player with the
record" philosophy: a downloaded .html file works offline against any
file the user can open, with no network dependency at runtime.
Newly vendored under shared/vendor/:
- xlsx.full.min.js (SheetJS, 928 KB) — XLSX/XLS preview
- utif.min.js (UTIF, 57 KB) — TIFF preview
Already there but now used by mdedit too:
- jszip.min.js, docx-preview.min.js
Call sites updated to drop the `await loadLibrary(URL)` pattern —
since the vendor JS is concatenated into the inline <script> at build
time, window.XLSX / window.JSZip / window.UTIF / window.docx are
available synchronously from page load.
Per-tool changes:
- archive/build.sh: +xlsx, +utif
- classifier/build.sh: +xlsx, +utif
- transmittal/build.sh: +xlsx, +utif
- mdedit/build.sh: +jszip, +docx-preview, +xlsx, +utif
(mdedit was the only tool not yet
bundling any of the preview deps)
- browse/build.sh: +utif
- archive/js/table.js, classifier/js/preview.js,
transmittal/js/files-preview.js, mdedit/js/file-tree.js (×2):
drop the `await loadLibrary('…cdn…')` lines.
- shared/preview-lib.js:
drop the loadLibrary(UTIF) / loadLibrary(JSZip) wrappers; assume
window.UTIF and window.JSZip are present.
Net bundle-size delta after baking:
archive: +990 KB → ~1.47 MB
browse: +57 KB → ~292 KB
classifier: +990 KB → ~1.43 MB
mdedit: +1100 KB → ~2.09 MB
transmittal: +990 KB → ~1.63 MB
Docs (AGENTS.md, ARCHITECTURE.md) updated: removed the "runtime CDN
loading exception" paragraph and the table row that flagged xlsx as
CDN-loaded.

mdedit's loadServerDirectory derived its file-tree root by stripping
back to the last "/" in window.location.href. For a no-trailing-slash
canonical URL (<project>/working) that gave the wrong root: the parent
project directory rather than working/ itself. Visible symptom on
zddc-server's auto-served URLs after the recent dispatcher changes —
mdedit at /Project/working would show the project's archive, working,
staging, etc. all together instead of being sandboxed to working/.
Detect the directory-shaped URL by checking whether the last path
segment contains "." (file marker). No dot = directory; treat the
whole path as the root and append the trailing slash internally.
/Project/working → root /Project/working/ (was /Project/)
/Project/working/x/y/ → root /Project/working/x/y/ (unchanged)
/Project/x/mdedit.html → root /Project/x/ (file URL; unchanged)

mdedit's toc.js exported updateToc / clearActiveTocItem / setActiveTocItem
as window.* globals, which was the only remaining violation of the
two-globals discipline (only window.app and window.zddc are intended).
Other tools either use IIFE + window.app.modules.X, or — like mdedit —
declare top-level functions that are reachable across concatenated files
without going through window.
Removed the three window.* exports and unqualified the four call sites
in events.js, editor.js (×3), and file-system.js. setActiveTocItem was
already called bare elsewhere; the change is just dropping a
window.foo && check chain that's now unnecessary.
No behavior change — TOC generation and click-to-scroll work as before.
mdedit's three Playwright tests still pass.

Replaces the binary acl.allow/deny model with five permission verbs
(r/w/c/d/a) and first-class roles, and adds an authenticated file API
(PUT/DELETE/POST move/mkdir) so the HTML tools can edit-in-place over
HTTP. Closes the AC-3(7) and AC-6 federal-readiness gaps.
File API (zddc/internal/handler/fileapi.go)
- PUT <new> → action c
- PUT <existing> → action w
- PUT <.zddc> → action a (CanEditZddc strict-ancestor rule)
- DELETE → action d
- POST mkdir → action c (auto-writes creator-owned .zddc when the
parent is Incoming/Working/Staging)
- POST move → action w on src + c on dst, atomic via os.Rename
- Optional If-Match for optimistic concurrency, --max-write-bytes cap,
audit log emits a structured file_write event per operation.
Permission model (zddc/internal/zddc/{acl,file,roles,cascade_mode}.go)
- acl.permissions: { principal → verb-set } map; principals are email
patterns or role names. Empty verb set is an explicit deny.
- roles: { name → members } definitions, available at the level they
declare and all descendants. Closer-to-leaf shadows ancestor.
- Legacy acl.allow/deny still work; they fold into permissions at
parse time (allow → "rwcd", deny → "").
- Cascade walks leaf→root; first level with any matching entry wins;
the union of matching verb sets at that level decides.
- --cascade-mode=strict adds a root→leaf ancestor-deny pre-pass so an
ancestor explicit-deny is absolute (NIST AC-6). Default delegated
preserves the existing commercial behavior.
Special folders (zddc/internal/zddc/special.go)
- Incoming / Working / Staging: mkdir auto-writes a .zddc into the new
subdir granting created_by + that email rwcda directly. Same form
operators write by hand; creator can edit it later to add others.
- Issued / Received: server-enforced WORM split. Cascade grants
inherited from above the WORM folder are masked to r only; grants
placed at-or-below the WORM folder retain r,c. Operators grant
write-once (cr) to the doc controller via an explicit .zddc at the
Issued/Received folder. Admins exempt — only escape hatch.
Browser polyfill (shared/zddc-source.js)
- HttpDirectoryHandle + HttpFileHandle implement the FS Access API
surface (values, getFileHandle, createWritable, removeEntry,
queryPermission/requestPermission) over zddc-server's listing JSON
and file API. Existing tools written against showDirectoryPicker
work unchanged.
- detectServerRoot() returns { handle, status }: tools auto-load on
HTTP, surface a clear "no permission to list" message on 403, and
fall back to the welcome screen on 0.
- classifier renames take the atomic POST move path on HTTP-backed
handles; mdedit and transmittal route reads/writes through the
polyfill so prior FS-API code paths cover both modes.
Tests
- zddc/internal/zddc/{cascade_mode,roles,special,acl}_test.go cover
delegated vs strict, role membership / shadowing / legacy fallback,
WORM split semantics, verb-set parser round-trip.
- zddc/internal/handler/fileapi_test.go now also covers role-based
vendor scenarios, WORM blocking vendor & doc controller writes,
explicit Issued .zddc unlocking the cr drop-box, admin bypass,
auto-ownership on mkdir, and strict-mode lockouts.
Docs
- ARCHITECTURE.md + zddc/README.md document the verb model, role
syntax, special-folder behaviors, cascade-mode flag, and full file
API surface. Federal-readiness gap analysis strikes AC-3(7) and
AC-6.

Bring every tool's header in line with archive's pattern:
[logo] [title] [version] [Add Local Directory] [⟳] ............... [◐] [?]
------------- header-left --------------- ----- header-right -
Changes per tool:
* browse: rename "Select Directory" → "Add Local Directory"; add the
red-non-stable wrap to the build label (was missing); add a help
panel + bundle shared/help.js.
* classifier: rename selectDirectoryBtn → addDirectoryBtn,
refreshBtn → refreshHeaderBtn for consistency. Update all JS
callers and welcome-screen copy to the new label.
* mdedit: same id rename. Move the previously-in-pane refresh
button into the header. Stop renaming the dir button to
"Directory: <name>" once a folder is loaded — instead use the
shared btn--subtle variant to de-emphasize while keeping the
standard label.
* transmittal: convert non-standard <div class="app-header"> with
spacer/icons containers to <header class="app-header"> with the
canonical header-left/header-right pair. Move the publish split-
button into header-left (Transmittal-specific primary action).
Remove dead .app-header__spacer/__icons/header-icon-btn CSS now
that nothing references those classes.
* landing, form: add help-btn + help-panel + bundle shared/help.js.
Each panel is tool-specific (project picker docs for landing,
schema-driven form docs for form).
Cross-cutting:
* shared/base.css: promote .btn--subtle from browse/css/tree.css
so any tool with an online mode can de-emphasize Add Local
Directory consistently.
Verified all 7 tools in headless Chromium: header structure correct,
build label red on non-stable cuts, help panel opens + closes via
button + Esc.
Two issues from one session:
* File tree: ZDDC-conforming filenames render as a single line
even though the JS already produced two-div markup (filename-main +
filename-secondary). Cause: .tree-row__label was display:flex
(row-direction), so the two divs laid out side-by-side. Fix: wrap
each label's text in a new .tree-row__name span styled
flex-direction:column. Both file and folder code paths use the
same wrapper now; non-ZDDC entries collapse to a single
.filename-main line so typography stays consistent across the tree.
Tested by injecting a ZDDC filename into a mock directory and
asserting filename-secondary's bounding-box top is below
filename-main's bottom.
* Toast UI Editor was unreadable in dark mode. Toast UI ships with
light-only chrome; its .toastui-editor-md-container has color #222
on a transparent bg, so when mdedit's dark theme rendered the
surrounding pane in #1e1e1e the editor text fell on near-black
background → effectively invisible. Fix: add CSS overrides in
mdedit/css/editor.css that target the editor's load-bearing
surfaces (md-container, md-preview, ww-container, ProseMirror,
toolbar, mode-switch tabs, popups) and apply var(--bg) /
var(--text). Toolbar icons get a filter:invert(0.85) hue-rotate
to flip the sprite-baked dark glyphs. Both manual override
(data-theme="dark") and OS-pref auto fallback (prefers-color-scheme)
are covered. Tested by computing contrast ratios on every editor
surface in dark mode — all came in at 10:1+ (well above WCAG AA's
4.5:1).
Embedded snapshots refreshed to current main HEAD's dev build label.

Adds shared/preview-lib.js with two cross-tool renderers:
- renderTiff (UTIF.js, lazy-loaded from CDN; PDF-style toolbar with
page nav, zoom, fit-width/fit-page; multi-page TIFFs decode lazily)
- renderZipListing (JSZip; sortable name/size/modified table, sticky
header, host-grouped paths)
Wired into the four tools that have a preview surface (archive, classifier,
mdedit, transmittal). Cross-document compatible so the same renderer works
for popup-window tools (archive/classifier/transmittal) and inline tools
(mdedit). Archive previously had no image branch at all — now previews
JPG/PNG/GIF/WebP/BMP/SVG natively, plus TIFF via UTIF, plus the ZIP listing.
Adds the dark-blue rounded-square favicon to each app's header (left of
the title) and to the website navigation. Single inline SVG, sized via
.app-header__logo (in shared/base.css) for tools and .brand-logo (in
website/css/style.css) for the website. Self-contained — the SVG carries
its own background, no wrapper styling needed.

Bundles a stretch of in-progress work across the SPA tools so the
tree returns to a coherent shippable state ahead of cutting a new
zddc-server stable image:
- landing: substantial rework of the project picker (sortable/filterable
table, presets refactor, ?projects= filter, ?v= channel propagation,
loading/error states)
- archive: presets cleanup, source.js refactor, filtering/url-state
alignment with the landing page
- mdedit: file-system module split, resizer, file-tree improvements,
base/toc styling tweaks
- transmittal/classifier: small template touch-ups for shared chrome
- shared: build-lib.sh helpers, new favicon.svg
- bootstrap, build.sh: pick up the channel-aware install/track zip
generation
- tests: new landing.spec.js, expanded archive/mdedit/build-label specs
- docs: CLAUDE.md picks up the zddc-server section and freshens the
alpha-build exception note
- regenerated artifacts: install.zip, track-{alpha,beta,stable}.zip,
*_alpha.html — these are produced by `sh build.sh` and per project
convention are committed alongside the source changes

ZDDC — Zero Day Document Control. A file-naming convention plus five
single-file HTML tools (archive, transmittal, classifier, mdedit,
landing) and an optional Go HTTP server (zddc-server) with ACL and a
virtual archive index. Self-contained, offline-capable, dependency-free.
See README.md for an overview, AGENTS.md and ARCHITECTURE.md for the
build/release/architecture detail, bootstrap/README.md for the
two-level deployment install pattern, and zddc/README.md for the
HTTP server.
