Three coordinated changes that share the same files. Common theme:
convention beats exception. Where the codebase had a bespoke wire shape
or a special-case route, replace it with the generic shape every other
client already speaks.
== Listing protocol ==
GET / Accept: application/json used to dispatch to a bespoke
ServeProjectList handler returning {name, url, title} per project — a
shape that diverged from every other directory's listing.FileInfo
response. Now:
- listing.FileInfo gains an optional `title` field (read from each
directory's own .zddc title:). Generic clients (landing, browse)
read the same shape from every URL.
- appfs.ListDirectory emits a virtual `.zddc` entry (is_dir:false,
virtual:true) when no on-disk file exists at that path and the
caller asked for ?hidden=1. Opens an editable view of the cascade
defaults; PUT-saving its bytes materialises a real file.
- The bespoke GET / JSON branch in cmd/zddc-server/main.go is gone.
The bare-root landing serve is Accept-gated: HTML requests get the
landing tool (project picker), JSON requests fall through to
ServeDirectory and get the generic listing.
- landing's fetchProjects filters the new generic shape (is_dir,
strip trailing slash) — same pattern fetchParties already used at
/<project>/archive/.
== Form editor retirement ==
`<dir>/.zddc.html` was a server-rendered form for editing per-directory
.zddc files (~900 LOC across zddceditor.go, zddchandler.go, zddc_assets.go).
Browse's YAML/CodeMirror editor (with .zddc-schema lint) already edits
the same files via the generic file-API. Two ways to edit the same data
is exception, not convention.
- Delete zddceditor.go, zddchandler.go, zddc_assets.go and tests.
- `/<dir>/.zddc.html` → 302 redirect to `/<dir>/?file=.zddc` (browse
opens the .zddc in its editor pane).
- /.profile/zddc/* namespace deleted (REST API + assets sub-route).
- Profile page's "Editable .zddc files" list links to browse.
- ServeZddcFile's 405 message + virtual-body comment point at the
browse URL instead of the dead form.
== Admin elevation (Principal model) ==
Sudo-style: admins are treated as normal users by default; opting into
admin powers is per-request and gated by a `zddc-elevate=1` cookie.
- zddc.Principal{Email, Elevated} replaces bare-email arguments on
IsAdmin / IsSubtreeAdmin / CanEditZddc. The signature change makes
the elevation gate compiler-enforced at every admin call site —
audit-fragility is gone. The empty-email short-circuit is no longer
load-bearing for elevation; Principal.gate() is the explicit check.
- handler.ACLMiddleware derives Elevated per request: bearer tokens
are implicitly elevated (CLI clients can't toggle a cookie); browser
sessions elevate only when zddc-elevate=1 is set. PrincipalFromContext(r)
is the one-call-per-site bundling helper.
- Every admin-check call site updated to pass a Principal.
- /.auth/admin (forward_auth target for the dev-shell IDE) explicitly
bypasses elevation with a synthetic-elevated Principal — different
cookie scope than zddc-server origin, documented inline.
- AccessView gains CanElevate (elevation-independent "does this email
have admin authority anywhere?") so the header toggle can render
itself for an un-elevated admin who hasn't opted in yet.
- ServeProjectList is removed; ProjectInfo + EnumerateProjects stay
for the profile page's server-rendered project list.
- MatchAppHTML stays — still used by main.go to route <dir>/<tool>.html
URLs to the apps subsystem when no real file exists.
- Test helpers carry Elevated=true by default (matches the
pre-elevation default; tests for the un-elevated gate use the
explicit form).
Go tests pass across all 14 internal packages. Browse + every other
tool rebuilds clean.

Adds a UI checkbox next to the existing Sort dropdown that surfaces
hidden entries when ACL would otherwise allow read. Default off
(matches today's filtered behavior). On toggle, browse re-fetches
the current directory with ?hidden=1 and re-renders.
┌─ browse toolbar ─────────────────────────────────────────────┐
│ Sort: [Name (A→Z) ▾] ☐ Show hidden │
└──────────────────────────────────────────────────────────────┘
Server-side surface:
- internal/fs/tree.go ListDirectory gains an `includeHidden bool`
parameter. The .-prefix filter (previously hard-coded) now also
drops _-prefix entries (matches dispatch's reserved-prefix guard)
and honors the new flag.
- internal/handler/directory.go reads `?hidden=1` from the request
and threads it through.
- cmd/zddc-server/main.go dispatcher relaxes its dot-prefix and
_-prefix guards for GET/HEAD when `?hidden=1` is set, so clicking
a hidden entry's link works. `_app/` (apps cache) stays
unconditionally reserved — those bytes must go through the apps
resolver. Writes to hidden paths stay blocked (the file API has
its own segment check that the flag does NOT relax).
- internal/listing/listing.go: signature parity (the lower-level
helper that's used by tests + non-cascade listing paths).
Security model unchanged: the ACL chain on the parent dir is the only
real gate. Whoever can read the dir can see its contents — toggling
"Show hidden" just stops the client-side filter from masking
.-prefixed and _-prefixed entries. Hidden paths today:
• <dir>/.zddc ACL YAML — already exposed via /.profile/zddc
• <dir>/.converted/<base> cached MD→DOCX/HTML/PDF, same sensitivity as source
• <root>/.zddc.d/tokens/ per-token metadata; filename = sha256(token)
so not bearer-usable. Default root ACL
restricts to admins; matches /.tokens UI.
• <root>/.zddc.d/logs/ access logs; same admins-only audience
• <root>/_app/ cached upstream tool HTML (public)
• <root>/_template/ install.zip scaffolding (public)
None of these contain bearer credentials or secret material that the
existing ACL doesn't already gate. The walls are still the cascade.
The HTML→PDF path produced PDFs where content extended past the
right margin of each letter page. Two contributing causes in
viewer-template.html's @media print rules:
1. .content-wrapper carries max-width: min(900px, 100%) from the
screen layout. The print override set width: 100% but didn't reset
max-width. Chromium's --print-to-pdf renders at the full page
width (816px for letter at 96dpi) and only clips at print time,
so without max-width: none the element actually extends past the
~624px printable area.
2. Tables, preformatted blocks, and long URLs had no print
containment. A wide <pre> or a <table> with many columns would
blow out the right edge even when the parent constraints held.
Fixes applied to @media print:
- html, body, .app-container: explicit width: 100% + max-width: 100%
to be sure the print viewport flows top-down with no horizontal
creep at the layout root.
- .content-wrapper: max-width: none + width: 100% (was just width).
- .content-page: width: 100% added (was just max-width: none).
- .document-content: max-width: 100% + box-sizing: border-box so
the existing 0.5in horizontal padding stays inside the page.
- pre/code/table/blockquote/img/video: max-width: 100% +
overflow-wrap: break-word; <pre> additionally white-space:
pre-wrap + word-break: break-word so unbreakable token runs
(URLs, paths, command lines) wrap instead of overflowing.
- table: table-layout: fixed so columns shrink to fit rather than
forcing horizontal scroll/overflow.
Both source files (pandoc/viewer-template.html and the embed copy at
zddc/internal/convert/viewer-template.html) updated and verified
identical with diff -q.
The HTML→PDF stage failed with:
Creating shared memory in /dev/shm/.org.chromium.Chromium.XXXXXX
failed: Read-only file system (30)
Unable to access(W_OK|X_OK) /dev/shm: Read-only file system (30)
Chromium tries to put its IPC shared-memory segments under /dev/shm
by default. Our container runs --read-only with /dev/shm inherited
from the image (which makes it read-only too). The well-known fix is
the --disable-dev-shm-usage chromium flag, which routes those
allocations to /tmp instead.
/tmp is a writable tmpfs we already set up. Bump its size from
128 MiB to 256 MiB so chromium has room for both its user-data-dir
and the redirected shared-memory segments. A small PDF flow used
~64 MiB free of 128 MiB available; doubling gives headroom without
materially changing the pod's memory footprint (tmpfs only consumes
RAM for bytes actually written).
The discardable_shared_memory_manager warning ("Less than 64MB of
free space in temporary directory") in the prior chromium log was a
symptom of this same /tmp-too-small condition; the bump quiets it
too.
Other warnings in the log (dbus connect failures) are not load-
bearing — chromium falls back gracefully when dbus is absent. No fix
needed there.
zddc-server can now invoke podman as a CLIENT against a remote socket
instead of creating containers in its own process. The sidecar pattern
in tnd-zddc-chart will use this so zddc-server's own pod stays
unprivileged (only the podman-system-service sidecar runs privileged).
New surface:
--convert-podman-socket / ZDDC_CONVERT_PODMAN_SOCKET
e.g. unix:///var/run/podman/podman.sock
Empty (default) → local mode (podman creates containers in
zddc-server's own filesystem namespace).
Non-empty → remote mode: `podman --remote --url=<this> run …`
dispatches each container request to whatever process owns the
socket. Typically a `podman system service` sidecar in the same
Kubernetes pod.
--convert-scratch-dir / ZDDC_CONVERT_SCRATCH_DIR
Host-side directory for per-conversion intermediates (template,
HTML, PDF). In remote mode this MUST be a path the sidecar sees
at the same mountpoint — typically a shared emptyDir at /work
in both containers. Empty = $TMPDIR (local-mode default).
Runner behaviour:
local mode → unchanged. `podman run --userns=host --rm --pull=missing
--network=none --read-only …`. `--userns=host` stays so nested-podman
on a privileged host (the previous chart shape) keeps working for
anyone still using it.
remote mode → `podman --remote --url=<sock> run --rm --pull=missing
--network=none --read-only …`. `--userns=host` is dropped because
the sidecar is rootful inside its own privileged container and
doesn't need userns juggling.
Health probe gains a Mode field ("local" | "remote") and, in remote
mode, runs `podman --remote --url=<sock> version` to confirm the
sidecar's socket is reachable. Unreachable-socket → 503 with a clear
reason (sidecar may still be starting up); reachable → ready.
Capabilities log now includes engine_version + mode + remote_url for
easier debugging of "which podman is actually doing the work".
No tests removed — the existing fake-runner table covers both modes
since the runner's args are uniform (remote prefix is the only thing
that differs).
When zddc-server runs inside a Kubernetes pod and shells out to
`podman run`, the inner podman tries to set up its own user namespace
via /usr/bin/newuidmap. The mapping fails inside the pod's namespace
even with privileged: true:
newuidmap: write to uid_map failed: Invalid argument
Error: cannot set up namespace using "/usr/bin/newuidmap": exit status 1
Adding --userns=host to the inner `podman run` tells it to reuse the
caller's user namespace instead of creating a new one — newuidmap
isn't invoked. The chart already runs the pod privileged so reusing
its userns adds no new privilege; --cap-drop=ALL + --network=none +
--read-only + --tmpfs continue to isolate the inner container.
On a bare-metal host invocation, --userns=host means "no userns
remapping at all", which is the default for rootful podman and works
identically to the prior behavior — the bitnest test setup and any
laptop dev runs are unaffected.
Smoke-tested locally with the exact flag set: pandoc/latex:latest in
a --userns=host --read-only container produces valid HTML from
`# Hello world` on stdin.
mdedit/ is gone. Its functionality moved into browse's preview plugin
(browse/js/preview-markdown.js) — YAML front matter editing, outline,
and on-demand DOCX/HTML/PDF download all happen there. Browse is the
default_tool for working/ + reviewing/ as of the previous commit, so
existing URLs of the form /<project>/working land on browse without
operator action.
Removed:
• mdedit/ source tree (Toast UI app, CSS, JS, template, build.sh)
• zddc/internal/apps/embedded/mdedit.html (//go:embed blob)
• tests/mdedit.spec.js + the "mdedit" project in playwright.config.js
• mdedit entries in zddc/internal/apps/embed.go (//go:embed, var,
switch case in EmbeddedBytes)
• "mdedit" in zddc/internal/zddc/validate.go AppNames + the matching
error-message app list
• "mdedit.html" branch in zddc/internal/apps/handler.go MatchAppHTML
• mdedit case in tests (handler_test.go, validate_test.go,
zddchandler_test.go) — test fixtures now use browse/classifier
• mdedit from build (per-tool build.sh loop, tool-list literals,
composer cards) and shared/build-lib.sh ZDDC_RELEASE_TOOLS
• mdedit from freshen-channel's tool list and usage banner
• mdedit-specific paragraphs in AGENTS.md and ARCHITECTURE.md;
Markdown Editor section in ARCHITECTURE.md rewritten to point at
browse/js/preview-markdown.js
• mdedit from CLAUDE.md, README.md, zddc/README.md tool lists
Historical mdedit_v*.html / mdedit_v*.html.sig files in
/srv/zddc/releases/ on the deploy host are immutable history — they
stay where they are. The next ./build release cut will simply not
produce new mdedit_v* artifacts.
Flip default_tool from `mdedit` to `browse` (which now ships a Toast UI
markdown editor plugin in its preview pane) at:
• paths."*".paths.working
• paths."*".paths.working.paths."*" (per-user homes)
• paths."*".paths.reviewing
available_tools at those levels drops `mdedit` and adds `browse` next
to `classifier`. Operator overrides per .zddc cascade still work; only
the embedded baseline changes.
Test fixtures updated:
• lookups_test.go — DefaultToolAt assertions for working/+reviewing/
• availability_test.go — AppAvailableAt + DefaultAppAt for working/+
reviewing/+per-user home
• main_test.go — dispatch route asserts "ZDDC Browse" (was "ZDDC
Markdown"); Apps cascade fixture swaps mdedit
for browse so the live route fetches the right
embedded HTML
New endpoint GET /<path>/foo.md?convert=docx|html|pdf renders a markdown
source on demand. Surfaced as the Download buttons in browse's markdown
editor (separate commit).
Execution model — two upstream container images, lazy-pulled:
• docker.io/pandoc/latex:latest — MD→DOCX, MD→HTML (entrypoint pandoc)
• docker.io/zenika/alpine-chrome — HTML→PDF (entrypoint chromium-browser)
No custom image build. The runner passes --pull=missing on every podman/
docker invocation so the operator only needs the runtime installed —
first request pulls the image, subsequent requests use the local cache.
Overrides: --convert-pandoc-image / --convert-chromium-image (and the
matching ZDDC_CONVERT_* env vars). Engine: --convert-engine (podman
preferred, docker fallback). Resource caps: --convert-mem-mib (512),
--convert-cpus (2), --convert-pids (100), --convert-timeout (30s).
PDF flow is two-stage: pandoc renders the markdown through the embedded
viewer-template.html to standalone HTML, then chromium prints that HTML
via --print-to-pdf. Preserves the print-media CSS already authored in
viewer-template.html rather than going through pandoc's LaTeX template.
Each conversion runs in a throw-away container with --rm --network=none
--read-only --tmpfs=/tmp --cap-drop=ALL --security-opt=no-new-privileges
--env=HOME=/tmp plus a bind-mounted scratch dir for I/O. Pandoc reads
markdown from stdin / writes to stdout; the viewer template lives at
/tpl (ro). Chromium reads HTML from a read-write bind mount at /pdf
and writes the PDF to the same mount; the host reads it back. No shell
wrappers, no shell quoting — argv flows straight into each image's
entrypoint.
On-disk cache at <dir>/.converted/<base>.<ext> with mtime synced to the
source. Fast path is a stat-and-serve with no exec; slow path
singleflights concurrent requests for the same target. PUT/DELETE/MOVE
on the source .md purges the .converted/ sidecars.
Per-project template variables (client/project/contractor/project_number)
come from a new .zddc `convert:` cascade block, walked leaf→root with
per-key latest-wins. Filename-derived variables (title, tracking_number,
revision, status, is_draft) come from a new zddc.ParseFilename helper.
If neither podman nor docker is on PATH, the endpoint serves 503 with
a clear Retry-After. The rest of the server keeps working.
This is the first os/exec site in the codebase. The hardening in
internal/convert/runner.go — context.CancelFunc → process kill,
cmd.WaitDelay, platform-specific SysProcAttr (Setpgid + Pdeathsig on
Linux), minimal env, stdout cap via limitWriter, stderr ring buffer —
sets the pattern for any future shell-outs.
Public surface:
convert.ToDocx(ctx, source, meta) / .ToHTML / .ToPDF
convert.Probe(ctx, engineOverride) → install Runner if engine present
convert.SetImages(pandoc, chromium)
convert.ConfigureLimits(memMiB, cpus, pids, timeout)
convert.Available()
Container handler at internal/handler/converthandler.go; dispatcher
branch in cmd/zddc-server/main.go inserts the convert lookup after the
existing ACL gate, reusing the source file's read policy verbatim.
The .zddc cascade-config migration retired the hardcoded folder-name
predicates (special.go's IsAutoOwnPath/IsWormPath/…) in favour of a
baked-in defaults.zddc.yaml with a recursive paths: tree, but several
top-level docs still described the old model:
- README.md / CLAUDE.md: "tools auto-served at folder-name-driven
paths (classifier in Incoming/Working/Staging, …)" → now: which tool
a URL serves is the cascade's default_tool/dir_tool/available_tools;
added the .zip-as-directory + GET /dir/?zip=1 + show-defaults notes;
CLAUDE.md's shared/ inventory refreshed (zip-source.js, fonts, …).
- ARCHITECTURE.md: the "Cooperating layers" table's "Special folders"
row (referenced special.go, the retired "WORM split") → rewritten as
"Canonical-folder behaviour" driven by the auto_own/worm/virtual/
drop_target .zddc keys; the "ACL cascade" row now mentions the
defaults.zddc.yaml bottom layer + paths: walker.
- zddc/README.md: role resolution was described as "shadows" → it's a
union with reset:true; WORM was "path-based, not cascade-based" → it's
the worm: cascade key; the "Special folders" section rewritten as
"Canonical-folder behaviour via .zddc keys" (a key table + the .zip
/?zip=1 notes), pointing at show-defaults as the authoritative ref.

zddc-server can now hand back a whole directory subtree as a single
streamed application/zip download: GET /some/dir/?zip=1 (works on both
/dir and /dir/) → Content-Type: application/zip + Content-Disposition:
attachment; filename="<dir>.zip", containing every readable file under
/some/dir/, recursively.
handler.ServeSubtreeZip walks the tree with filepath.WalkDir, ACL-gates
each file by the .zddc chain of its containing directory (per-dir
decision cache, same shape as serveArchiveListing), skips hidden
entries ("." and "_" prefixes — .zddc, _template, _app), and adds a
.zip *file* it encounters as opaque bytes (it does not recurse into it
— that's the navigable-virtual-surface feature, a different thing).
The response is streamed (zip.NewWriter straight onto the
ResponseWriter, Store for already-compressed extensions, Deflate
otherwise), so a fully-ACL-denied or empty subtree just yields a valid
empty zip rather than a 403 (a stream can't change status after the
headers go out; empty leaks no more than 403). HEAD sends the headers
and no body. The dispatch's directory ACL gate still runs first, so a
viewer who can't read the directory gets 403 before the handler.

zddc-server can now browse into a .zip file without the client
downloading the whole archive:
- GET …/Foo.zip/ → JSON listing of the zip's members
(Accept: application/json), or the
browse SPA (HTML) — same content
negotiation as ServeDirectory/.archive
- GET …/Foo.zip/sub/doc.pdf → extracts and streams that one member
(Range / ETag / conditional GET via
http.ServeContent)
- GET …/Foo.zip → unchanged: the raw .zip download
- PUT/DELETE/POST …/Foo.zip/… → 405 (zip access is read-only)
New internal/zipfs package reconstructs directory levels from the zip's
flat central directory (synthesising intermediate dirs with no explicit
"<dir>/" entry, mirroring what browse does client-side with JSZip) and
drops zip-slip-unsafe entries ("..", absolute, backslash). New
handler.ServeZip wraps it. The dispatcher gets splitZipPath + an
intercept placed before the file-API branch (so a write to a path under
a .zip is refused, not silently mkdir'd); ACL is the chain of the
directory CONTAINING the zip — a zip carries no .zddc of its own, same
as the .archive virtual surface. The os.Stat-per-segment walk is gated
by a cheap ".zip/" substring check so ordinary requests are unaffected.
Also fixes two pre-existing dispatch-test failures uncovered along the
way: a non-existent top-level "*.html" URL was 302'ing to its slash
form (because the bare "*" project glob makes every first-level segment
"declared") — the cascade-declared no-slash block now requires a
directory-shaped URL (trailing slash, or no file extension); and the
stale TestDispatchSlashRouting expectation that archive/<party>/mdl/
302s to mdl/table.html was updated to match the intended behaviour
(the default-MDL virtual fallback shows the browse listing there; only
a real on-disk tables: + *.table.yaml triggers the bounce).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The trailing-slash directory form was hardcoded to serve `browse`. Add a
`dir_tool` .zddc key (cascades leaf→root, floors at `browse`) so an
operator can point a subtree's slash form at another directory-oriented
tool — the symmetric counterpart to `default_tool` (the no-slash
"specialized app"). handler.ServeDirectory now resolves it via
zddc.DirToolAt; JSON listing requests are unaffected (raw listing
always served, so browse can still enumerate).
Also collapse the no-slash dispatch: the on-disk-directory and the
virtual-declared-path branches in main.go each carried their own copy
of "default_tool → tables-carveout-or-apps.Serve → 302", with
inconsistent ACL checks. Extract one chokepoint, serveSpecializedNoSlash,
that enforces ACL uniformly for every default_tool route.
Updates ARCHITECTURE.md and AGENTS.md: the stale "Special folders" /
hardcoded-availability sections now describe the .zddc-cascade model
(defaults.zddc.yaml, the schema-key table, the slash/no-slash
convention, WORM, standard roles).

The file API's mkdir post-hook still seeded auto-own .zddc files via the
hardcoded IsAutoOwnPath path-segment predicate, while
EnsureCanonicalAncestors had already moved to the cascade's auto_own:
flag. Point the hook at AutoOwnAt / AutoOwnFencedAt so both paths agree
and an operator's .zddc reshaping actually takes effect — fenced when
the new directory's own cascade level declares auto_own_fenced (per-user
working homes), unfenced otherwise.
Retires IsAutoOwnPath and WormMask (the latter already superseded by
WormZoneGrant's & VerbsRC) plus their tests, and the now-unused
path/filepath import in special.go.

Clarify the incoming/ semantics per the workflow: it's the
counterparty's drop zone, not a free-for-all.
- project_team gets read only here (inherited from the project
level — they have no c/w, so they can see what's been dropped
but not touch it). No change in effect; documented explicitly.
- document_controller gets rwcd here (restated at the incoming/
cascade level). The QC + transfer workflow — classifier renames
files in place (w), then they move to received/ (delete here +
worm-create there) — needs the delete bit, which the inherited
project-level `rw` lacked.
- The counterparty's uploader still gets access via a deployment
.zddc (acl: { permissions: { "*@acme.com": cr } } at
archive/Acme/incoming/.zddc) or by mkdir'ing a dated subfolder
under incoming/ and owning it via the existing auto_own — both
flows unchanged.
Test: standardroles_test now asserts the doc controller has rwcd at
incoming/ and a project_team member has only r there.
All Go + Playwright tests green.

Answers "can roles reset as well as add?" — yes, both now.
Role membership UNIONS across the cascade:
- A deeper .zddc that defines an inherited role again with one
extra member ADDS that member (was: deepest definition shadowed
the ancestor's entirely).
- New `reset: true` on a role definition breaks the union — that
level's members are authoritative, ancestor definitions above
are excluded; descendants below still union on top. Use it to
give a project its own team independent of a deployment-wide
default.
- lookupRoleMembers / RoleMembers reworked: walk deep→shallow,
union members, stop at the first reset:true; finally fold in
chain.Embedded.Roles as the baseline so a role declared only in
defaults.zddc.yaml is "defined" (and a deployment's on-disk
redefinition unions on top).
Admin checks are now role-aware:
- IsSubtreeAdmin / CanEditZddc's strict-ancestor scan use
MatchesPrincipal instead of MatchesPattern, so `admins:
[document_controller]` resolves to the role's members. The
strict-ancestor scan resolves roles only up to level i, so a
role defined at the deepest level (= dirPath) never confers
self-edit rights.
Two standard roles ship in defaults.zddc.yaml (empty members — a
fresh deployment grants nothing until they're populated):
document_controller — files into the WORM zones. Gets:
- rw at the project level (read + overwrite-existing; NOT c, so
it can't make arbitrary folders)
- rwc at archive/ (can create party subfolders)
- subtree-admin at working/ and staging/ (full create + manage,
including taking over a fenced per-user home) — scoped HERE,
not at the project root, so the WORM constraint still binds
it in archive/<party>/received|issued
- listed in worm: on received/ and issued/ → write-once-create
survives the WORM mask
project_team — read-only across the project. The per-user
working home's fenced auto-own .zddc (rwcda for the creator)
wins via deepest-match, so "read-only except what I own" falls
out of the cascade with no special rule. Inside received/issued
their r is preserved (worm: doesn't strip read).
archive/<party>/ gains `auto_own: true` (UNFENCED) so whoever
creates a party subtree (normally the doc controller) owns it and
can set up that counterparty's .zddc afterward — without fencing,
project_team:r still cascades through to received/issued.
Tests: roles_test (union + reset), standardroles_test (the
doc-controller scoped-create matrix + project-team read-only-except-
owned), ensure_test updated for the new party-folder auto-own.
fileapi_test's WORM doc-controller test already uses worm: [role].
All Go + 248 Playwright tests green.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Per design feedback: the verb string in a worm: entry was always
effectively "cr" (the key's whole job is to restore write-once-create
inside the locked zone, and you need read to see what you filed), so
spelling it out per-entry was redundant. worm: is now just a list of
principal patterns — email-globs, @role:name, or bare role names —
and every listed principal gets read + write-once-create. An empty
list ([]) still marks the WORM zone with no create-capable
principals.
Changes:
- ZddcFile.Worm: map[string]string → []string
- mergeOverlay: concat-dedupe (a deeper .zddc adds controllers);
mergeStringSlicePreserveEmpty keeps `worm: []` non-nil through
the overlay so it still marks the zone
- WormZoneGrant: walks the list, grants VerbsRC to each matching
principal; result is always ⊆ {r, c}
- ValidateFile: validates each entry as an email-glob (role refs
skipped — validated by the role machinery)
- defaults.zddc.yaml: received/ and issued/ carry `worm: []`
- tests updated to the list form (worm_test.go, fileapi_test.go)
All Go tests green.

WORM (write-once-read-many) is no longer a special folder type keyed
off the literal names "received"/"issued". It's a cascade key —
`worm:` on any directory's .zddc — with the ACL-shaped semantics the
user described.
Schema:
worm:
"doc-control@example.com": cr # email-glob or @role:name → verbs ⊆ {r, c}
# an empty map ({}) is a WORM zone with no create-capable principals
Effect inside a WORM zone (any cascade level declares worm:), applied
AFTER the normal cascade ACL and BEFORE the admin escape hatch:
- w / d / a stripped for everyone
- c survives only via the worm: map
- r survives via the normal ACL OR the worm: map (so a document
controller who isn't in the project ACL still gets read+create)
- worm: grants UNION across the cascade — deeper .zddc can name
more controllers
- admins (root / subtree) bypass entirely — handler does the
IsAdmin check before the policy evaluator
defaults.zddc.yaml: archive/<party>/received and archive/<party>/issued
carry `worm: {}` (WORM zone, no controllers — the deployment names
its document controller by adding a deeper .zddc with
`worm: {<principal>: cr}`). The canonical convention is unchanged;
the difference is an operator can now mark any directory WORM, or
rename received/issued, without a code change.
Removed (hardcoded path predicates, superseded by the cascade walk):
zddc.IsWormPath
zddc.WormFolderLevelIndex
zddc.splitPathSegments (only IsWormPath used it)
Kept: zddc.WormMask (generic verb-set primitive), zddc.VerbsRC.
New:
zddc.WormZoneGrant(chain, email, mode) → (verbs, inWormZone)
Walks the chain for worm: declarations; unions the principal's
grants masked to {r, c}.
policy.InternalDecider.Allow: WORM block rewritten to consult
WormZoneGrant instead of IsWormPath/WormFolderLevelIndex.
ValidateFile: worm: keys validated as email-glob (or @role:name);
values validated as verb strings ⊆ {r, c}.
Tests:
- new worm_test.go covers the embedded convention, operator-granted
controller, w/d masking, cross-cascade union.
- special_test.go's TestIsWormPath / TestWormFolderLevelIndex
retired; TestWormMaskStripsWDA kept.
- fileapi_test.go's WORM tests updated: the doc-controller grant is
now `worm: { _doc_controller: cr }` at issued/.zddc, not
`acl.permissions: { _doc_controller: cr }`.
- federal-parity and admin-bypass tests unchanged — the WORM mask
still strips w/d/a and admins still bypass.
All Go tests green.

The shared/nav.js stage strip previously hardcoded four stages
(archive/working/staging/reviewing) with their labels and target
URLs baked into the file. Operators couldn't add a fifth stage or
rename "Working" to "In-Progress" without forking shared code.
Now cascade-driven end-to-end:
Server-side:
listing.FileInfo gains a Declared bool field. fs.ListDirectory
stamps Declared=true on every entry whose name matches the
cascade's ChildrenDeclaredAt(parent) — both real on-disk dirs
and virtual canonical injections. Bugfix in the same patch:
virtualCanonicalFolders was passing the relative dirPath to
ChildrenDeclaredAt (which expects absolute); now passes absDir.
Client-side:
shared/nav.js fetches the project root's JSON listing on
DOMContentLoaded, filters to declared+is_dir entries, sorts by
canonical workflow order (archive → working → staging →
reviewing, then any extras alphabetically), and renders the
strip. Labels read e.display_name → falls back to titleCase(name).
Hardcoded FALLBACK_STAGES kicks in only on fetch failure
(offline / file:// / non-zddc-server backend). Rendered
immediately so the strip appears without flicker, then the
cascade-fetched list replaces it once available.
Effect:
Project-3 (which has display: { archive: "Records",
working: "In-Progress", ... } in its .zddc) now shows
"Records · In-Progress · Outbox · Pending Responses" in every
tool's strip. Project-1 still shows "Archive · Working ·
Staging · Reviewing". No code change to render either; the
cascade decides.
Tests:
- tests/nav.spec.js relies on the mock server returning HTML at
every URL, so the fetch fails over to fallback stages — the
test renders the same Archive/Working/Staging/Reviewing labels
it always did, with no test changes needed.
- All 248 Playwright + all Go tests green.
Remaining client-side hardcode: archive/js/source.js +
archive/js/app.js's mode detection. Phase 4d.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.

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.

Phase 3 retired these symbols by migrating their consumers to the
.zddc cascade lookups. Removing them now that nothing references
them:
- var zddc.ProjectRootFolders
- var zddc.PartyFolders
- var zddc.AutoOwnCanonicalNames
- var zddc.VirtualOnlyCanonicalNames
- func zddc.IsProjectRootFolder
- func zddc.IsArchivePartyFolder
- func zddc.IsArchivePartyMdlDir
- func handler.isArchivePartyDir
The canonical convention is expressed in defaults.zddc.yaml and
consulted via lookups.go's DefaultToolAt / AutoOwnAt / VirtualAt /
IsDeclaredPath / ChildrenDeclaredAt / AvailableToolsAt /
IsToolAvailableAt. Operators override per-directory via on-disk
.zddc files; the embedded layer is the documented baseline.
Test removals:
- TestCanonicalLists (lists no longer exist)
- TestIsProjectRootFolder (function no longer exists)
Equivalent coverage lives in lookups_test.go's
TestDefaultToolAt_FromEmbeddedConvention,
TestIsDeclaredPath_FromEmbeddedConvention, etc. — which assert the
convention via the cascade's actual lookup path rather than the
predicates' return values.
handler.isAtArchivePartyMdlDir is RETAINED — it's still actively
consumed by RecognizeTableRequest's default-MDL fallback in
table.html URL resolution. That's a tighter file-path predicate
than the cascade walker would naturally express; can revisit if it
ever needs to become configurable.

Final consumer migration. The Go-coded lists that previously encoded
the ZDDC convention all defer to the .zddc cascade now.
Schema added:
available_tools: [tool1, tool2, ...] concat-union across cascade;
tools not in the union are
denied auto-route at that path
auto_own_fenced: true|false generated auto-own .zddc
carries inherit:false (private
to creator)
Lookups added:
AvailableToolsAt(root, dir) union of available_tools across cascade
IsToolAvailableAt(root, dir, tool)
AutoOwnFencedAt(root, dir) leaf-only
Cascade semantics finalised (per field):
default_tool → leaf→root walk (parent applies to descendants)
available_tools → leaf→root union (each level adds; baseline at root)
auto_own → leaf-only (creating THIS dir specifically)
auto_own_fenced → leaf-only (same)
virtual → leaf-only (THIS dir is virtual, not subtree)
Consumers migrated:
apps.DefaultAppAt → zddc.DefaultToolAt
apps.AppAvailableAt → zddc.IsToolAvailableAt (+ landing special)
EnsureCanonicalAncestors → AutoOwnAt + AutoOwnFencedAt
fs.ListDirectory empty-list fallback → zddc.IsDeclaredPath
fs.virtualCanonicalFolders → zddc.ChildrenDeclaredAt
dispatcher canonical-folder branches → unified into one
cascade-declared block
Hardcoded helpers REMOVED (dead code):
apps.inAncestorWithName
zddc.autoOwnDepthMatch / isAutoOwnDepthMatch
Hardcoded lists kept as data sources for the cascade walker but
no longer drive routing logic:
ProjectRootFolders / PartyFolders / AutoOwnCanonicalNames /
VirtualOnlyCanonicalNames / IsProjectRootFolder / IsArchivePartyFolder /
IsArchivePartyMdlDir — all still defined; only `ProjectRootFolders`
is used by special.go's IsProjectRootFolder. The rest are dead.
Dispatcher unified: the previously-two branches (per-party folder vs
project-root folder) collapse into one cascade-declared-path block
that handles the slash/no-slash convention uniformly:
- no-slash, default_tool=tables → ServeTable (default-MDL fallback)
- no-slash, default_tool set → apps.Serve(tool)
- no-slash, no default_tool → 302 to slash form
- slash, any → ServeDirectory empty-list fallback
The IsDir branch's switch also un-hardcoded — any cascade tool is
served (not just the legacy 3 names), so e.g. /Project/archive/<party>
/incoming (no slash) now serves classifier directly rather than 302'ing
to the slash form.
defaults.zddc.yaml populated with the canonical convention as the
recipe. Operators edit it (or override per-directory on disk) to
change any behaviour — no Go code changes required.
Browse drag-drop scope (working/staging/incoming) is the one remaining
client-side hardcoded regex; cascading that requires the cascade JSON
to be served to the client, which is its own Phase 4 piece.
Tests updated for the new no-slash mdl URL convention (landing MDL
card test) and no-slash stage URLs (nav strip test). All 248
Playwright + all Go tests green.

Two pieces:
1. Lookup helpers walk chain.Levels from leaf back to root. The
"parent applies to descendants unless overridden" cascade rule
means a working/ default_tool=mdedit propagates to deep paths
like working/alice@example.com/notes/sub/deep without anyone
declaring it at every level. AutoOwnAt and VirtualAt follow the
same walk; explicit false at a descendant can override an
ancestor's true (*bool semantics).
2. apps.DefaultAppAt delegates to zddc.DefaultToolAt. The hardcoded
switch on parts[1] (archive→archive, staging→transmittal,
working→mdedit, reviewing→mdedit, mdl→tables) and its case-
sensitivity quirks now live in defaults.zddc.yaml. Operators can
override any of these per-directory with an on-disk .zddc; no
code change required.
Semantic improvement: archive/<party>/incoming previously defaulted
to "archive" (because parts[1]=archive and the switch didn't look
deeper). The new convention routes it to "classifier" — incoming/ is
the bulk-rename surface, not a record browser. Updated
availability_test.go to reflect.
All other DefaultAppAt cases — including case-fold (Archive/MDL),
mdl override, reviewing virtual, project root returning "", random
non-canonical names returning "" — produce bit-identical output.
Two new tests in lookups_test.go cover the propagation:
- TestDefaultToolAt_PropagatesToDescendants
- TestAutoOwnAt_DescendantCanDisable
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Schema:
- default_tool: string (tool name served at this dir's no-slash URL)
- auto_own: *bool (mkdir post-hook auto-grants the creator)
- virtual: *bool (never materialise on disk; aggregator routes)
defaults.zddc.yaml: populated with the full canonical convention via
paths:. Top-level "*" matches any project; nested archive/working/
staging/reviewing declare the project-stage tools; archive's "*" /
mdl|incoming|received|issued tree declares the per-party surfaces.
All four party folders and all four project-root folders get their
default_tool; working / staging / archive/<party>/incoming get
auto_own; reviewing / archive/<party>/mdl get virtual. None of these
need on-disk dirs to exist.
Lookups (zddc/internal/zddc/lookups.go):
DefaultToolAt(root, dir) → cascade-resolved default tool name
AutoOwnAt(root, dir) → does mkdir auto-own here?
VirtualAt(root, dir) → never materialise on disk?
IsDeclaredPath(root, dir) → does the cascade say anything about this dir?
ChildrenDeclaredAt(root, dir)→ literal child names declared by Paths
Each looks up via EffectivePolicy → leaf level → Embedded fallback,
so operators' on-disk overrides win and the embedded baseline carries
the convention.
Tests cover the embedded convention, operator overrides, and
inherit:false blocking the embedded layer. No consumer migration yet
— that's Phase 3b. Behaviour is bit-identical for current callers
since none of them consult the new lookups.

Adds the recursive paths: schema and the cascade walker that threads
ancestor virtual contributions through to descendant levels.
Schema:
paths:
"*": # literal-segment or "*" segment-wildcard key
paths: # recursive — each step matches one segment
archive:
paths:
"*":
paths:
incoming:
title: "demo"
Each on-disk .zddc and the embedded defaults can declare paths:; the
walker collects every matching subtree and merges its contributions
into chain.Levels[depth] using mergeOverlay (per-field overlay with
on-disk most specific). The matched glob descends one segment at a
time; the value's own paths: becomes a new virtual source for deeper
matches.
Semantics:
- matchGlob: literal key first (case-insensitive on segment),
"*" wildcard fallback.
- mergeOverlay: top wins per-field on scalars; maps merge key-by-
key with top overriding; lists concat-dedupe; Paths replaces
(recursive walker threads it through naturally).
- inherit:false at any on-disk level drops accumulated ancestor
virtual sources AND zeroes chain.Embedded — the operator owns
every rule from that level outward.
- Behaviour is bit-identical when no .zddc declares paths:; the
walker reduces to the prior linear cascade.
Eight new tests cover the glob match table, ancestor-paths
contribution, on-disk-wins override, paths-absent bit-identical
behaviour, and inherit:false dropping ancestor paths: contributions.
All existing tests still pass.
Phase 3 next: populate defaults.zddc.yaml with the canonical
ZDDC convention via paths:, and replace apps.DefaultAppAt /
AppAvailableAt / AutoOwnCanonicalNames / VirtualOnlyCanonicalNames /
IsProjectRootFolder / IsArchivePartyFolder with cascade lookups.

First step of the .zddc-first-configuration rollout: pure plumbing
that makes the future move-everything-out-of-Go work mechanically
possible without changing any current behaviour.
New pieces:
1. zddc/internal/zddc/defaults.zddc.yaml — a real YAML file in the
repo. Single source of truth for the baked-in baseline; intentionally
minimal in Phase 1 (just title + empty acl) so existing deployments
stay bit-identical until Phase 2 starts populating the schema.
2. //go:embed (defaults.go) bakes the bytes into the binary so
shipped deployments don't need the file. Operators who want a
starting point export with:
zddc-server show-defaults > /var/lib/zddc/root/.zddc
3. PolicyChain gains an Embedded ZddcFile field. EffectivePolicy
layers in the embedded defaults as a baseline below the on-disk
chain. Consumers that want the full effective view consult both;
existing consumers that only read chain.Levels keep working
bit-identically (the new field is additive).
4. New top-level `inherit:` key on ZddcFile. Default true. Set
`inherit: false` on any on-disk .zddc to zero out chain.Embedded
— the operator owns every rule from that level outward. Useful at
the on-disk root to fully reject the embedded defaults; useful at
deeper levels for sandbox subtrees.
5. `zddc-server show-defaults` (also accepts --show-defaults) subcommand
dumps the embedded bytes to stdout — same shape as --print-rego.
No flag plumbing needed beyond the existing args walk.
6. Tests: parse-roundtrip on the embedded file, presence in chain by
default, inherit:false drops it, explicit inherit:true is a no-op
versus the default.
Phase 2 (next): add a `paths:` recursive map + `default_tool:` /
`auto_own:` / `virtual:` keys, populate defaults.zddc.yaml with the
canonical ZDDC convention, and migrate apps.DefaultAppAt /
AutoOwnCanonicalNames / VirtualOnlyCanonicalNames to cascade lookups.

Three coupled fixes:
1. landing MDL card: Open button now navigates to /<project>/archive/
<party>/mdl (no trailing slash) so the tables tool loads. The
slash form would route to browse instead, which is not what users
want when they click "Open MDL".
2. zddc-server canonical-folder fallback extended to
archive/<party>/{mdl,incoming,received,issued}. New
zddc.IsArchivePartyFolder() recognises any of the four party
folders at depth 4. fs.ListDirectory returns [] for missing
on-disk variants (mirroring the project-root behavior added in
commit 3fc3717); the dispatcher routes slash forms to
ServeDirectory and the no-slash mdl form to ServeTable, with
non-mdl no-slash forms 302'ing to the slash form.
So /Project-N/archive/<party>/incoming/ now lands on an empty
browse listing rather than 404 when nobody has dropped files yet.
3. Fixture seeded with 3 files per party under incoming/ — naming
intentionally NOT in transmittal-envelope form, so classifier
(loaded automatically by browse's grid mode at /incoming/
per the URL-driven view convention) has something to rename.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The shared header strip pointed Working/Staging/Reviewing at the slash
form (working/, etc.), which now serves browse per the slash/no-slash
convention established earlier. The user expected those links to open
the stage's tool (mdedit for working, transmittal for staging, etc.) —
which is what the no-slash form serves.
Also drops the .html suffix from the archive target: <project>/archive
(no slash) → archive tool, same as the other stages. The currentStage
recognizer still accepts /archive.html as a fallback for any direct
URLs that survive in bookmarks.

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.

Two related routing fixes:
1. /<project>/archive/<party>/mdl[/] now follows the slash/no-slash
convention uniformly with the rest of the system:
- mdl (no slash) → tables app (default tool for mdl/)
- mdl/ (slash) → browse (ServeDirectory empty-listing fallback)
Previously the slash form auto-redirected to mdl/table.html, which
forced the user into the table view from any party-folder click and
produced a confusing "Unrecognized table URL" error when the
redirect race-conditioned. tableRowsRedirect now only redirects
when a real on-disk table.yaml exists; the default-MDL virtual case
stays in browse via the convention.
New zddc.IsArchivePartyMdlDir helper recognises the canonical
<project>/archive/<party>/mdl pattern at depth 4 (relative path).
fs.ListDirectory uses it to return [] for the missing-on-disk case
so browse renders the empty workspace cleanly. Test updated
(TestServeDirectoryRedirectsDefaultMdl → TestServeDirectoryDefaultMdlNoRedirect).
2. <dir>/.zddc URLs now work at every directory depth.
The dispatcher previously 404'd anything beginning with a dot
(except /.archive and /<dir>/.zddc.html). New IsZddcFileRequest +
ServeZddcFile handlers carve out the raw .zddc leaf so an operator
can navigate to /Project-1/archive/PartyA/mdl/.zddc and inspect
the rules effective at that depth.
Semantics:
- Method: GET / HEAD only. Writes go through the existing admin-
gated form at <dir>/.zddc.html (unchanged).
- ACL: parent directory's read permission gates access; 404
(not 403) is returned to non-readers so existence isn't leaked.
- On disk: file bytes served verbatim with
Content-Type: application/yaml and X-ZDDC-Source: file:<rel>.
- Virtual: when no file exists at this level, a synthetic
placeholder body is returned with a YAML-comment cascade
summary so the reader sees exactly what rules apply here from
ancestors. X-ZDDC-Source: virtual:zddc distinguishes it.
The virtual body parses as valid YAML (`{}` after the comments) so
downstream tooling that consumes the URL isn't confused.

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.

Wires up live alpha-dev iteration on bitnest. With this change a
`.zddc apps: <tool>: <path>` entry overrides the embedded copy for any
of the eight tools, not just five.
Two coupled fixes:
1. zddc.AppNames had a five-entry list (archive/transmittal/
classifier/mdedit/landing) — predating browse/form/tables.
ResolveWithOverride's `if !IsKnownApp(app)` gate silently rejected
those three before ever looking at the cascade, falling back to
embedded with an "unknown app" error.
2. handler.ServeDirectory hard-coded `apps.EmbeddedBytes("browse")`
for the HTML directory-listing fallback, bypassing the apps
subsystem entirely. Now takes an optional *apps.Server and
delegates to appsSrv.Serve(w, r, "browse", chain, absDir) when
wired, so the cascade is honored at bare directory URLs too
(the most common way browse gets surfaced).
Both call sites in main.go and the test signatures in
directory_test.go updated. ValidateFile error message now lists all
eight known apps.
Verified end-to-end on bitnest with a root .zddc apps cascade
pointing at /srv/.zddc.d/source/<tool>/dist/<file>: every `./build`
on the host is now immediately visible after a hard refresh. Iteration
loop is `./build` (or `sh tool/build.sh`) then reload — no container
restart needed, since the apps subsystem reads the path source on
each request.

Above the Groups / Projects cards, a horizontal strip of one link per
tool — each pointing at the latest stable single-file build on the
canonical release host (zddc.varasys.io/releases/<tool>_stable.html).
Useful for "try this tool" / offline use without first picking a
project.
Seven links (Archive, Transmittal, Classifier, Markdown, Browse, Form,
Tables). Landing itself is omitted from the strip — clicking landing
from landing is a no-op. Each card has the tool name in the display
serif and a short sans hint underneath. Wraps on narrow widths instead
of scrolling horizontally; sits inside pickerView so it auto-hides on
the per-project landing view.

Only transmittal had any @media (max-width) rules; the other seven
tools silently break below ~900px. Adds a baseline shared rule that
every tool inherits — desktop-first stays the same, but a tablet in
landscape or a window split next to a document remains usable.
@media (max-width: 800px):
- tighter header padding + gaps
- .app-header__title drops 18px → 16px
- .build-timestamp inside .header-title-group hidden (it's

The header is the first thing a user sees. A short staggered fade-in
(logo → title → action button → right-side icons over ~360ms) turns the
instant-pop-in feel into a subtle "the tool is composing itself" beat.
Pure CSS @keyframes (no JS), cubic-bezier(0.2, 0.7, 0.2, 1) for the
"settle in" easing curve. Respects prefers-reduced-motion. Total budget
~260ms before everything is visible — well under the threshold where it
becomes a perceptible delay.

System-default font stack ('-apple-system, BlinkMacSystemFont, Segoe UI,
…') is the textbook generic admin-tool look. The tools have a real point
of view (engineering documents, traceability, immutability); the
typography should reflect that.
Picks:
--font → IBM Plex Sans (400 + 600). UI body text. Distinctive
engineering sans with tabular nums and proper figures.
--font-display → Source Serif 4 (600). Headings, page titles,
.app-header__title. Reads as "document" not "UI label."
--font-mono → unchanged. Platform mono fonts are already excellent
and engineering tools rarely benefit from a custom mono.
Wiring:
- Raw .woff2 files live in shared/fonts/ (~60 KB total, latin subset,
SIL OFL 1.1 — both families)
- shared/fonts.css is base64-inlined data URIs for those three fonts
(~80 KB after b64 overhead). Generated once from the snippet in
shared/fonts/README.md.
- Every tool's build.sh prepends shared/fonts.css before shared/base.css
so @font-face is parsed before any rule references the family names.
- Headings (h1-h6) and .app-header__title now use var(--font-display);
.app-header__title bumped 17→18px and letter-spacing reset since the
serif doesn't need the original sans-text tightening.
- table/code/.tabular-nums get font-variant-numeric: tabular-nums so
tracking-number columns align vertically.
"Ship the record player with the record": zero CDN dependency at render
time. Tools render identically offline and online. Per-tool dist sizes
grew by ~80 KB.

There are 76 alert() call sites across the eight tools — three different
ad-hoc error-surfacing patterns (alert, console.error, classifier's own
showToast). Touching every site is a sweep with no judgment payoff:
every alert is "something went wrong, the user should know," which is
exactly what toast at level='error' is for.
Shim is one if-block at the bottom of shared/toast.js. It saves the
native window.alert as window.alertNative (so any truly modal-blocking
call site can opt back in by name), then replaces window.alert with a
function that forwards through window.zddc.toast(msg, 'error'). Effect
is global — every existing alert in every tool becomes a non-blocking,
ARIA-announced (aria-live=assertive) toast that the user can click to
dismiss.
handler/tables.html refreshed by ./build as a side effect (it bakes the
current tables/dist/ into the binary every build).

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).

301 Moved Permanently is cached by browsers effectively forever — when
we changed /<project> no-slash from "redirect to slash form" to
"serve project landing" earlier today, anyone who had visited the URL
under the prior behavior got stuck on the cached 301 indefinitely. No
server-side fix is possible after the fact; only a manual cache clear
in each user's browser releases the binding.
Demote every routing-shape redirect to 302 Found, which browsers do
not cache by default. Five sites:
- handler/directory.go: no-trailing-slash → slash on directory URLs
- main.go (4 sites):
.archive/ canonicalization (deep /<project>/<sub>/.../.archive/
path collapses to /<project>/.archive/)
reviewing/<tracking> no-slash → slash
reviewing/ default-app fallback to slash form
generic IsDir + no-slash + no-default-tool fallback
301 → 302 trades "permanent semantics in the protocol" for "we can
change our mind later without trapping users on old behavior." For
these routes — all of which are convention-driven shapes the server
owns — the latter is what we want.
Test updates: five httptest assertions switch from
http.StatusMovedPermanently → http.StatusFound, plus five comment
strings ("301" → "302").

The /<project> landing page was server-rendered via
internal/handler/projecthandler.go's html/template — an inconsistency
against the project's "every tool is a single-file HTML" convention.
Convert it to a mode of the existing landing/ tool: same bundle now
serves both / (project picker) and /<project> (project workspace).
Mechanics:
- landing/template.html: pickerView (existing markup) + projectView
(new: stage cards, browse-all, MDL section, party-list slot).
Mode toggles by adding/removing .hidden on the two containers.
- landing/js/landing.js: detectMode() reads location.pathname;
renderProjectMode() populates stage hrefs from the project segment
and fetches /<project>/archive/?json=1 for the party list. init()
forks based on mode; picker init was extracted to initPicker().
Existing public API + behaviour unchanged for picker mode.
- landing/css/landing.css: appended ~115 lines for the project view
(.stages grid, .stage-card hover, .party-list, MDL formatting).
- cmd/zddc-server/main.go: dispatcher's IsProjectRootURL fork now
calls appsSrv.Serve(w, r, "landing", chain, absPath) rather than
the deleted ServeProjectLanding handler.
- internal/handler/projecthandler.go: trimmed to just the
IsProjectRootURL predicate (the dispatcher still needs it for
routing). Template + render code (~220 lines) deleted.
Net effect: same UI as before — same logo wrapping (now via
shared/logo.js, no longer a hand-rolled inline anchor), same stage
cards, same MDL instructions with party links — but the page is now a
single-file SPA that themes like the rest, follows the same logo and
stage-strip conventions, and could in principle be downloaded and
served standalone.
Tests:
- 3 new tests/landing.spec.js cases: detectMode exposure, project
workspace renders at /<project> with correct stage hrefs + title,
party listing populates from JSON fetch and filters dot-prefixed
entries.
- The dispatcher test for /Project no-slash still asserts 200 +
no-redirect; the served body is now landing.html instead of the
server-rendered template, but both pass the assertion.
LOC: roughly net-neutral. -220 in projecthandler.go, +115 in
landing.css, +130 in landing.js, +60 in template.html.

The project landing page at /<project> had its own hand-rolled
header with <svg class="logo"> — not the canonical app-header__logo
class, and not loading shared/logo.js. So the logo on that page was
purely decorative while every other tool's logo (in the same beta
build) was wrapped by shared/logo.js into a clickable link to
/<project>. Inconsistent and surprising — clicking the logo from
mdedit/archive/etc. takes you to project landing, but clicking the
logo on project landing did nothing.
Inline the wrap directly in the template (the page is server-
rendered, so it can't lean on shared/logo.js the way bundled tools
do):
<a class="app-header__logo-link" href="/" title="ZDDC home">
<svg class="app-header__logo" ...>...</svg>
</a>
href="/" because "next up" from the project landing is the
deployment root (the project picker / landing tool).
Also rename .logo → .app-header__logo for visual consistency, and
add the matching hover/focus styles inline. The test asserts both
the wrapping anchor and the canonical class name.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The .app-header__logo SVG was decorative on every tool. Web's
strongest convention is "click logo → go home" — so users tapping
it expecting that fallback got nothing. Now the logo is wrapped in
an anchor whose href reflects the URL the page was loaded from:
file:// → no wrap (no server home to point at)
/ → wrap, href=/ (deployment root)
/index.html / /<tool>.html → wrap, href=/ (root, no project)
/<project>/... → wrap, href=/<project> (project landing)
The wrap happens client-side at DOMContentLoaded via shared/logo.js,
loaded by every tool's build.sh after toast/nav. Idempotent — a
template-supplied anchor or a second mount call is a no-op.
The companion shared/logo.css adds a subtle hover/focus affordance
(opacity 0.82, focus ring) so the logo reads as clickable without
otherwise altering its visual weight. Tools opt out by setting
window.zddc.logo.disabled = true before DOMContentLoaded (e.g. for
deployments that pin the logo to an external destination).
Five Playwright tests (tests/logo.spec.js) lock the contract:
no-wrap on file://, href=/ at root, href=/<project> in project
subtree, aria-label matches target, idempotent re-mount.

GET /<project> (no trailing slash) used to 301 to /<project>/ which
served the browse listing. Now it serves a small server-rendered
landing page with:
- Four lifecycle-stage cards (archive/working/staging/reviewing)
linking to the no-slash form of each canonical folder, so each
card opens its default tool (archive view, mdedit sandboxed to
working/, transmittal at staging/, mdedit at reviewing/).
- A "Browse all files" link to the slash form for the generic
file tree.
- A "Master Deliverables List" section with step-by-step
instructions for editing any party's MDL plus direct links to
the MDL of each party already present under archive/ (sorted,
case-preserved). Falls back to a friendly "no parties yet"
message when the archive is fresh.
Trailing-slash form (/<project>/) is unchanged — still 200 +
embedded browse.html. The slash-vs-no-slash convention now extends
all the way up the URL tree:
/ → landing tool (project picker)
/<project> → project landing (this commit)
/<project>/ → browse
/<project>/working → mdedit
/<project>/working/ → browse
... etc.
Implementation:
- new internal/handler/projecthandler.go — IsProjectRootURL
predicate + ServeProjectLanding rendering an inlined html/template.
Page styles are inline; tokens mirror shared/base.css and
auto-flip on prefers-color-scheme: dark.
- dispatcher in cmd/zddc-server/main.go: at the IsDir branch's
no-slash fork, intercept depth-1 single-segment URLs before
the historical 301. Other depths still 301 unchanged.
Tests:
- internal/handler/projecthandler_test.go (4 cases): predicate
coverage; landing page renders project name + four stage cards;
on-disk parties surface as MDL links with case preserved; fresh
project falls back to the no-parties-yet copy.
- cmd/zddc-server/main_test.go TestDispatchSlashRouting: the
"project root no-slash → 301" case becomes "→ landing (200)".

Apply the same slash-vs-no-slash convention to reviewing/ that already
governs the other three canonical project folders:
/<project>/reviewing → mdedit (default tool, via DefaultAppAt)
/<project>/reviewing/ → browse (HTML) — shows the aggregator's
virtual <tracking>/ entries as a tree
/<project>/reviewing/?json → aggregator JSON (handler.ServeReviewing)
Browse fetches the JSON listing for the URL it was loaded from, so
loading browse.html at /<project>/reviewing/ triggers a JSON request
back through the dispatcher → ServeReviewing → aggregator output.
Browse then renders the virtual <tracking>/ entries as clickable
folders. Clicking a tracking folder navigates to the per-submittal
view; clicking received/ or staged/ exits the virtual subtree
into canonical archive/ or staging/ paths via the polyfill's
explicit-url support.
The HTML branch in the reviewing dispatcher block was previously
calling appsSrv.Serve(..., "mdedit", ...) for trailing-slash URLs;
now it falls through to the canonical-folder block which routes to
ServeDirectory's HTML default (embedded browse.html).
Test: TestDispatchEmptyCanonicalProjectFolders extended with the
slash/<stage> → browse subtests, mirroring the no-slash → default
app set. All four canonical folders now have symmetric coverage of
both shapes.

When a user first writes to <project>/working/<email>/, the auto-own
.zddc EnsureCanonicalAncestors seeds at that folder now sets
acl.inherit: false in addition to the rwcda grant. This makes each
user's working subtree private by default — ancestor cascade grants
(e.g. a permissive *: r at the project root) no longer let anyone
read everyone else's drafts.
Implements the user-stated sandbox model: "no automatic or default
permissions other than the user's default folder which is instantiated
on first save — users can edit the .zddc files in their subtree to
allow access to others." The owner can edit
<project>/working/<email>/.zddc to add collaborators (or set
inherit: true, or list specific email patterns).
Mechanics:
- new WriteAutoOwnZddcFenced — same shape as WriteAutoOwnZddc plus
acl.inherit: false. Existing WriteAutoOwnZddc unchanged.
- autoOwnDepthMatch returns (autoOwn, fenced); idx 2 under working/
triggers fenced=true. The other auto-own positions
(depth 1: working/staging/, depth 3: archive/<party>/incoming/)
stay unfenced — those are shared lanes where ancestor admin
grants should still apply.
- staging/ children stay unfenced because staging folders are
date+tracking-named (shared lane), not per-user.
Tests:
- TestEnsureCanonicalAncestors_LazyCreation now asserts the fenced
.zddc exists at working/<email>/ with inherit: false.
- TestEnsureCanonicalAncestors_StagingChildNotFenced new — staging
children stay plain.

party/{received,issued}
The synthetic test fixture and many real deployments use PascalCase
folder names (Archive/, PartyB/, Received/, Issued/, Staging/). The
aggregator was hard-coding lowercase joins, which on case-sensitive
filesystems (Linux ext4) meant os.ReadDir returned NotExist and the
listing was empty even when the data was present.
Use zddc.ResolveCanonical to find the on-disk casing for each
canonical segment (archive/, staging/, then per-party received/ and
issued/), and emit URLs with the resolved casing so the dispatcher's
URL canonicalisation is a no-op pass-through.
The case-insensitive lookup was already used elsewhere (file API's
mkdir, tree.go's virtualUserHomeEntry); reviewing/ now matches that
convention.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Implements the reviewing/ aggregator described in the saved
project memory (~/.claude/projects/-home-user-src-zddc/memory/
project_reviewing_folder_design.md). reviewing/ stays in
VirtualOnlyCanonicalNames — never materialised on disk — and is
served as a join over archive/<party>/received/, archive/<party>/
issued/, and staging/, recomputed on every read.
Two depths, both trailing-slash:
GET <project>/reviewing/?json=1
→ array of virtual <tracking>/ entries, one per submittal in
archive/<party>/received/ that doesn't yet have a matching
archive/<party>/issued/ entry. Sorted by tracking. URLs stay
under reviewing/ so the user can drill into the per-submittal
view. ACL: per-party, filtered like fs.ListDirectory.
GET <project>/reviewing/<tracking>/?json=1
→ array of two virtual entries, received/ + staged/, with
canonical URLs pointing back to archive/<party>/received/...
and staging/... respectively. staged/ is omitted when no
response draft exists yet.
When the response moves staging/ → archive/<party>/issued/, the
entry vanishes from depth-0 on the next listing. No mutation of
the reviewing/ subtree itself; pure join, recomputed on read.
Front-end at <project>/reviewing[/<tracking>/] is mdedit (per
user request). DefaultAppAt + AppAvailableAt extended to recognise
"reviewing" as a canonical mdedit-bearing folder. The polyfill in
shared/zddc-source.js is updated to follow listing entries' explicit
url field when present (absolute or root-relative) — that's how
mdedit's tree follows the depth-1 received/ + staged/ links into
the canonical archive/staging subtrees.
Dispatcher routing in zddc-server/main.go:
- GET <project>/reviewing/[<tracking>/] with Accept: json
→ ServeReviewing
- GET <project>/reviewing/[<tracking>/] with Accept: html
→ mdedit (rooted at the virtual path; polyfill fetches the
JSON listing on its own)
- GET <project>/reviewing (no slash) → mdedit (via DefaultAppAt)
- GET <project>/reviewing/<tracking> (no slash) → 301 to slash form
Tests:
- handler/reviewinghandler_test.go (6 cases): IsReviewingPath
classification + ServeReviewing depth-0/depth-1 with and without
staged drafts + 404 on unknown tracking + empty when archive/ is
absent.
- apps/availability_test.go updated: reviewing/ now expects mdedit
rather than "" (no default).
- cmd/zddc-server/main_test.go: TestDispatchEmptyCanonicalProjectFolders
extended to assert reviewing → mdedit at the no-slash form;
older "no-slash/reviewing → 301" test removed.
Future work (not in this commit): write translation. Editing a file
under reviewing/<tracking>/staged/<f>.md works today because the
polyfill rewrites to /<project>/staging/<response>/<f>.md before
fetching — the user's URL bar moves to the canonical path on click.
A virtual-filesystem mode where the URL bar stays under reviewing/
throughout would require server-side write rewriting (translate
PUT/DELETE on reviewing/.../staged/... into the canonical staging/
path). Not needed for the MVP — links in mdedit's tree work.

when missing on disk
Mirror of the existing IsDir-branch behavior at line 873
(<project>/working → mdedit, <project>/staging → transmittal,
<project>/archive → archive) for the case where the folder doesn't
exist on disk yet. Without this, GET <project>/working on a fresh
project 404s instead of opening mdedit rooted at the (virtual)
working directory.
Behavior matrix for canonical project-root folders that don't yet
exist on disk:
GET <project>/archive → archive tool (project-root mode)
GET <project>/archive/ → empty browse listing
GET <project>/working → mdedit rooted at working/
GET <project>/working/ → empty browse listing (with synthetic
<viewer-email>/ home entry)
GET <project>/staging → transmittal rooted at staging/
GET <project>/staging/ → empty browse listing
GET <project>/reviewing → 301 to /reviewing/ (no default app)
GET <project>/reviewing/ → empty browse listing
GET <project>/random → 404 (still — non-canonical)
GET <project>/random/ → 404 (still — non-canonical)

The previous fix in fs.ListDirectory was insufficient — main.go's
dispatcher calls os.Stat(absPath) before reaching ServeDirectory,
and 404s on the missing path before the listing code ever runs.
Symptom: GET <project>/working/ on a fresh project still returned
"Not Found" despite the read-side fallback being committed.
Add the same fallback at the dispatcher level: when os.Stat returns
NotExist AND the URL ends with "/" AND the path matches
IsProjectRootFolder, fall through to ServeDirectory rather than
404. ServeDirectory's ACL check + ListDirectory's empty-listing
behavior take it from there.
Separately, fs.ListDirectory now initializes its result slice to
make([]listing.FileInfo, 0) instead of `var result []listing.FileInfo`,
so the JSON encoder emits "[]" rather than "null" for empty
listings — clients (browse, archive) expect an array and choke on
null.
New test TestDispatchEmptyCanonicalProjectFolders covers the four
canonical names (archive/working/staging/reviewing) on a project
where none of them exist on disk yet, plus the negative case (a
non-canonical missing path still 404s).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Listing <project>/{archive,working,staging,reviewing}/ when the folder
doesn't exist on disk now returns an empty 200 listing instead of 404.
The stage-strip nav links into these folders unconditionally; without
this fallback, clicking "Working" against a fresh project (where
working/ hasn't been written to yet) lands on a 404 page rather than
a usable empty view.
Mechanism stays consistent with the existing lazy-folder design:
- GET on missing canonical folder → 200 + empty listing (this commit)
- first WRITE under the same path → EnsureCanonicalAncestors
materialises the on-disk folder + auto-own .zddc
reviewing/ stays virtual-only (in VirtualOnlyCanonicalNames); the
fallback just makes its empty listing always renderable. The future
reviewing/ aggregator (recorded in project memory) will replace the
empty listing with the join-computed virtual entries.
The fallback is gated on IsProjectRootFolder — only depth-2 paths
matching one of the four canonical names. Non-canonical missing paths
still 404 (TestListDirectory_NonCanonicalMissing_StillNotFound).
For working/ specifically the synthetic <viewer-email>/ home entry
still fires from virtualUserHomeEntry, so the user sees their own
placeholder even when working/ doesn't exist yet — first write into
that placeholder triggers the lazy-create chain.

Beta cut of the eight HTML tools into zddc/internal/apps/embedded/*
and the unified form/tables bundle into zddc/internal/handler/tables.html.
Each tool's on-page label changes from alpha → beta-stamped bytes;
no source changes beyond the build label itself.
The dev image (Dockerfile, devshell, ZDDC_REF=main) and the bitnest
test container both pick this up automatically — bitnest's path-unit
fired on the rebuild of zddc/dist/zddc-server-linux-amd64 and
restarted the container with the new embedded apps:
embedded_apps=archive=v0.0.17-beta browse=v0.0.17-beta
classifier=v0.0.17-beta form=v0.0.17-beta
landing=v0.0.17-beta mdedit=v0.0.17-beta
tables=v0.0.17-beta transmittal=v0.0.17-beta
Source-side commits since the previous beta:
feat(landing): single-project click → <project>/archive.html
feat(shared): non-blocking toast helper
feat(shared): lateral project-stage strip
feat(form): standalone empty-state welcome
fix(tables): keepalive on beforeunload save path
refactor(mdedit): drop window.* TOC globals
refactor(archive): remove dead debounce
style(transmittal): tokenize utility classes, drop !important block
style: replace inline styles with CSS
test(shared): zddc-source.js + toast + nav specs
test(browse): smoke spec
docs: tool counts + state pattern + polyfill gaps

Adds a thin nav strip directly under the app-header showing the four
canonical lifecycle stages from the transmittal-workflow spec:
archive · working · staging · reviewing. Each is a link to that
stage's directory under the current project. Current stage is
highlighted (bold + primary color, aria-current="page"). Strip
mounts as a sibling of .app-header on DOMContentLoaded — no
template changes needed in any tool.
Render rules (shared/nav.js shouldRender):
- location.protocol must be http: or https: (file:// has no project
structure to navigate within)
- a project segment must be detectable as the first path segment
(when it isn't a tool HTML file like /index.html or
/archive.html?projects=A,B). Multi-project view at the deployment
root therefore shows no strip.
Stage URL targets:
- Archive → <project>/archive.html (project-root archive view)
- Working → <project>/working/ (directory listing — mdedit auto-served)
- Staging → <project>/staging/ (directory listing — transmittal auto-served)
- Reviewing → <project>/reviewing/ (directory listing)
Convention-driven, not probed: if a deployment doesn't have one of
these folders the link returns 404. Operators on non-standard layouts
can opt out by setting window.zddc.nav.disabled = true before
DOMContentLoaded.
This pairs with the previous landing-tool change (single-project
click → <project>/archive.html). Together they give the user
both URL-bar manipulation AND visible navigation across the four
canonical project stages.
Five Playwright tests in tests/nav.spec.js exercise:
- non-render at deployment root
- render + active stage on <project>/archive.html
- render + active stage deep inside <project>/working/foo/mdedit.html
- canonical link targets
- mount position is sibling of .app-header

Promote classifier's local toast (classifier/css/base.css + showToast
in classifier/js/excel.js) into shared/toast.{js,css}. Every tool's
build.sh now concatenates them, so window.zddc.toast(msg, level, opts)
is callable from any tool.
API:
window.zddc.toast('Saved.', 'success');
window.zddc.toast('Could not load: ' + err.message, 'error');
window.zddc.toast('Note', 'info', { durationMs: 3000 });
Levels: info (default) | success | warning | error. Single-toast
policy — a second call replaces the first. Click anywhere on the
toast to dismiss. ARIA: error → role=alert/aria-live=assertive,
others → role=status/aria-live=polite.
Class prefix is .zddc-toast (BEM-ish) to avoid colliding with any
tool-local .toast rules. Classifier's existing showToast now
delegates to window.zddc.toast — call sites in excel.js +
selection.js are unchanged. Classifier's local .toast CSS block
deleted in favor of the shared one.
This commit only EXPOSES the API. Replacing the ~25 alert() call
sites scattered across archive/transmittal/mdedit/classifier with
toast calls is left as follow-up — each alert needs per-call review
to decide if it's truly non-blocking.
Five Playwright tests in tests/toast.spec.js lock the contract:
API exposure, level mapping, ARIA roles, single-toast replace,
click-to-dismiss.

The TODO at save.js's unload handler was "switch to keepalive on save
for the unload path." flushAllDrafts() kicks off saveRow() per dirty
row when the page is being navigated away from, but those fetches were
not flagged keepalive — modern browsers can cancel them mid-flight as
the page unloads, dropping the user's last typing.
saveRow() now accepts an opts.keepalive flag that is passed through to
fetch(). flushAllDrafts() passes {keepalive: true} so the unload path
gets the keepalive guarantee. Normal saves are unaffected (keepalive
imposes a 64 KB body cap per the Fetch spec — only worth that trade
on the unload path).
Also refreshes the embedded zddc/internal/handler/tables.html bytes via
./build, which folds in this change plus the form welcome-state CSS
from c585112.

The repo grew tables and browse since the docs were last revised, but
several paragraphs still said "six HTML tools" / "all seven" / "5 HTML
+ zddc-server". Updated AGENTS.md, ARCHITECTURE.md, CLAUDE.md, README.md,
and zddc/README.md to consistently reflect the current count
(8 HTML + zddc-server = 9 artifacts).
Also expanded README.md's tool table to include browse and landing,
corrected the tables description (no longer read-only), and modernized
the "Build & develop" snippet to show the canonical lockstep
./build alpha|beta|release path instead of the deprecated per-tool
--release form.

Per the reference doc at zddc.varasys.io/reference.html#tracking-numbers,
a tracking number is composed of: originator, [phase], project,
[area], discipline, type, sequence, [suffix]. The default Master
Deliverables List now surfaces every component as its own column,
plus the standard MDL metadata (title, plannedRevision,
plannedDate, status, owner). Columns appear in the canonical
filename order so the table reads left-to-right like the tracking
number itself.
Optional components ([phase], [area], [suffix]) render in the
table even when blank — keeps the layout consistent across rows.
Projects on a schema that doesn't use them hide the columns by
overriding (see customization).
Form schema (default-mdl.form.yaml):
- One JSON Schema property per tracking-number component, plus
the deliverable metadata. originator / project / discipline /
type / sequence are required; phase / area / suffix are
optional. The schema is intentionally permissive — free-text
strings on every component, no enums or regex constraints.
Projects pick their own conventions for originator codes,
discipline vocabularies, etc.; a default that imposed a
fixed set would just get in the way.
- Phase 2's editable-cell widget factory derives the right
per-cell editor from this schema: text inputs for the
components, the existing select for `status` (which keeps
its enum), date input for `plannedDate`, textarea for
`notes`.
Customization (the "way for end users to customize"):
- Drop your own table.yaml and / or form.yaml into the rows
directory (archive/<party>/mdl/, or any directory hosting a
table). Operator-supplied files override the embedded defaults
ATOMICALLY — there's no field-level merge, the operator file
wins entirely. This matches every other "spec on disk wins"
convention in zddc-server.
- Hide a column: omit it from the columns: list.
- Rename a column header: change `title:`.
- Add a column: append a {field, title} entry AND add a
matching property in form.yaml's schema.properties.
- Tighten constraints: use `enum:`, `pattern:`, `minLength:`
etc. on form.yaml properties.
- Pre-filter rows on load: defaults.filter[<field>].
The whole rows-directory is self-contained — copying mdl/ to a
new project takes the spec, the form, and every row YAML
together.
Documentation:
- AGENTS.md "Tables system" gains a paragraph on the default-MDL
column set + the customization mechanism + a pointer to the
embedded source files.
- tables/template.html help panel rewrites the body to cover:
* What the directory IS (spec + form + row YAMLs together).
* Editable-cell keyboard shortcuts (the Phase 1-5 sequence
we just shipped — arrows, Tab, Enter, F2, Delete, Ctrl+D /
R / C / V / Z, Shift+arrow / Shift+click for ranges).
* The auto-save model + per-row state swatch colors.
* The customization model with a worked file-tree example.
Replaces the obsolete pre-Phase-1 wording that referenced
`*.table.yaml` parent files and click-to-navigate-row UX.
Tests: no schema test changes — the default YAMLs are loaded
through the same RecognizeTableRequest / RecognizeFormRequest
paths that already cover the fallback. Full Playwright + Go
suites green (44 + 13).

Final phase of the editable-cell sequence. Adds linear undo
(Ctrl/Cmd+Z), range selection (Shift+arrow, Shift+click), bulk
delete (Delete/Backspace), and fill-down/right (Ctrl+D / Ctrl+R)
across the selected range. Skips redo, drag-fill handle, and
formulas — those were the deferred items from the architecture
report's "build what spreadsheet refugees miss most in week one"
recommendation.
Undo (tables/js/undo.js):
- Linear command stack, depth 50, session-local. Each Command
is { cells: [{rowId, field, oldValue, newValue}, ...] }.
Single edits push a one-cell Command; bulk operations push
one Command spanning all affected cells so a single Ctrl+Z
reverts the whole group.
- Replay logic: for each cell in the popped command, compare
oldValue to the row's stored data. If they match → clear the
draft (the user's edit reverts to baseline). Otherwise →
setDraft to oldValue (intermediate state). Then app.repaint().
- Hotkey: document-level keydown for Ctrl/Cmd+Z. Bails when the
active element is an INPUT / TEXTAREA / contentEditable so
the browser's intra-input undo wins inside a focused editor.
- Pushed by every edit path: editor.commit, editor.bulkClear,
editor.bulkFill. Phase 4's clipboard.applyPaste path will
push from a future iteration — current paste tests don't
cover undo, but the wiring is symmetric.
- Why local-only and no redo: per the architecture report —
shared undo is conceptually broken under last-writer-wins;
redo is a power-user nicety we can add later as a parallel
forward stack (~10 lines).
Range selection (tables/js/editor.js):
- New state: app.state.range = {anchor, focus} | null. Anchor
is the cell where the range started; focus is the current
edge. The cell at focus also has tabindex=0 (the keyboard
focus owner).
- Shift+ArrowDown/Up/Left/Right: extends focus by one cell,
re-applies --in-range class to every cell in the bounding
rectangle.
- Shift+click on a cell: extends the range from anchor to the
clicked cell. Plain click clears the range.
- Escape clears both selection and range.
- Visual: --in-range cells get a fainter background; the
--selected cell (focus) keeps its bright outline so the
anchor/focus distinction is visible.
Bulk delete:
Delete or Backspace in nav mode (no editor mounted) clears
every cell in the current range, setting each to null in the
draft buffer. One undoable Command spans the whole range so
Ctrl+Z restores all cells together.
Fill-down / fill-right:
- Ctrl+D fills the top row's value down through the range
(Excel/Sheets convention). Each cell in the column below
the source row picks up the source row's effectiveCellValue
for its column. Cross-column variation preserved.
- Ctrl+R fills the left column's value right through the
range. Symmetric to Ctrl+D.
- Both push a single multi-cell Command.
Bug fix shipped alongside:
editor.commit and editor.cancel now ev.stopPropagation() in
addition to preventDefault. Without it, the input's keydown
on Enter bubbled up to the table's onCellKey listener AFTER
setSelected moved focus to the next row, which then re-fired
enterEdit on the new cell — a confusing "I committed but
landed back in edit mode" UX. The probe-driven test for the
single-cell undo path surfaced this; same root cause for any
focus-on-target-then-bubble pattern. Tab and Escape get the
same treatment for symmetry.
Tests (7 new Phase 5 specs, total 44 in tests/tables.spec.js):
- Ctrl+Z reverts a single cell edit to prior value — types in
one cell, asserts the draft applied, presses Ctrl+Z, asserts
the cell returned to its original AND the draft buffer is
empty (returned to baseline → no draft).
- Shift+ArrowDown extends range selection — verifies two cells
carry --in-range class.
- Shift+click extends range from anchor to clicked cell —
verifies a 2x3 selection produces 6 in-range cells.
- Delete clears every selected cell — verifies a 2x2 selection
produces 4 null drafts.
- Ctrl+D fills the top row down through the range — verifies
the second row's title cell takes the first row's title.
- Ctrl+Z reverts a bulk fill in one step — verifies a single
Ctrl+Z restores the original value AND clears the draft.
- undo stack depth caps at 50 — pushes 60 commands, asserts
depth saturates at 50 (oldest 10 dropped).

Bidirectional clipboard interop with Excel, Google Sheets, and any
other spreadsheet that uses RFC-4180-ish TSV on the text/plain
clipboard mime. Pasted cells write straight into the draft buffer
the same way per-key edits do; row-level save (Phase 3) picks them
up on the next row-blur with the same If-Match optimistic-
concurrency flow.
TSV parser (clipboard.js parseTSV):
- Tabs separate columns, \\n / \\r\\n separate rows.
- Quoted fields ("...") may contain tabs and newlines verbatim.
- Doubled \\"\\" inside a quoted field escapes a literal \\".
- Trailing empty row from a final \\n is dropped (Excel sends
this; matching the convention avoids a phantom blank row at
the end of every paste).
Apply-paste (clipboard.js applyPaste):
- Anchor = currently selected cell.
- 1×1 clipboard into selection → writes that one cell.
- N×M clipboard → SPILLS from the anchor down/right to
(anchor.row + N - 1, anchor.col + M - 1). Cells past the end
of either axis are silently dropped with a toast count.
- Each pasted value goes through coerceCell, which checks the
column's row-schema property type:
* number / integer → Number()
* boolean → "true"|"yes"|"1" → true; "false"|
"no"|"0"|"" → false
* everything else → raw string
Drafts hold the right JS type so the row-PUT body matches the
JSON Schema the server validates against.
Copy (clipboard.js onCopy):
- Single-cell selection: Ctrl/Cmd+C writes the cell's
effectiveCellValue (draft if dirty, else stored) as text/plain
via formatCell (RFC-4180 quoting on tab/newline/quote).
- Range copy is Phase 5 (depends on range-selection landing).
Event wiring:
- document.addEventListener('paste'/'copy') so events bubble
from any cell with focus. Phase 1's roving tabindex moves
focus around; per-cell binding would have to be re-applied
after every paint.
- onPaste bails when an editor input is mounted (the input
owns its own paste — typing into a cell editor that was just
populated with a chunk of TSV would be a footgun).
Toast for partial pastes:
When applyPaste skipped any cells, a small message in
#table-status: "Pasted N cells; M dropped (out of bounds)".
Auto-clears after 4s. Coexists with Phase 3's stale-row prompt
(toast doesn't fire if a prompt is already up; prompt outranks
toast).
Tests (6 new Phase 4 specs, total 37 in tests/tables.spec.js):
- parseTSV handles tabs, newlines, and quoted fields — covers
the parser edge cases including embedded \\n inside "..." and
doubled "" escapes.
- paste single value into selected cell — the 1×1 path; verifies
the draft buffer entry.
- paste 2×2 grid spills from anchor — the N×M spill semantic.
- paste coerces numeric/boolean values via row schema —
verifies the draft holds typeof===number for an integer column
and === true for a boolean column.
- paste out-of-bounds drops cells silently with toast — drives
via dispatched ClipboardEvent('paste') (the only way to
exercise onPaste end-to-end including the toast).
- copy single cell writes value to clipboard — synthesizes a
ClipboardEvent('copy') with a writable DataTransfer payload
and asserts the cell value lands in text/plain.

Cell edits now actually persist. Row-level batch save fires on
row-blur (selection moves to a different row); the request is one
PUT with the full merged row (server-side data + client drafts)
and If-Match: <etag> for optimistic concurrency. Conflict and
validation responses are surfaced inline; drafts are NEVER silently
discarded — when the server says no, the user's typing stays put
until they explicitly reload or replay.
Architecture (per the research synthesis from earlier in this
sequence):
- ETag tracking: context.js readRows captures the per-row ETag
from HttpFileHandle's response header on the initial GET.
Stashed at row.etag alongside row.data and row.yamlUrl. Phase 3
reads it; later phases (undo replay) inherit it.
- Row-blur trigger: editor.js setSelected calls a new
notifySelectionChanged() hook after selection lands. save.js's
onSelectionChanged tracks _previousSelectedRowId; when it
changes AND the previous row had drafts, fires saveRow(prevId).
Fire-and-forget — don't block the user's flow on the network.
- save.saveRow flow:
1. mergeRow(row.data, drafts) → full updated row.
2. js-yaml dump → wire body.
3. PUT row.yamlUrl, body, headers={Content-Type, If-Match}.
4. Branch on response status:
- 200/201 → success: clear drafts + invalid marks, capture
new ETag from response, replace row.data with merged.
- 202 → outbox queued (downstream client offline):
clear drafts (the outbox owns them now), mark row queued.
- 412 → stale: drafts STAY; mark row stale; show
status-bar prompt with [Use mine] / [Reload] buttons.
- 422 → server validation failed; body has
{errors: [{path, message}]}; mark each cell invalid via
a red-corner CSS marker + title-attribute tooltip.
- other → mark errored; drafts stay.
- Conflict resolution UX:
- "Use mine" replays the user's drafts onto fresh server
state. Re-GETs the row to learn the new ETag + new server
data, replaces row.data with the fresh server values, then
re-PUTs the merge of fresh + drafts. This is client-side
field-level last-writer-wins: fields the user did NOT
touch get the server's new values automatically; only
fields the user changed override server state. No JSON
Patch endpoint required — pure client logic on top of the
existing whole-row PUT path.
- "Reload" drops drafts entirely, re-GETs the row, repaints.
- Validation error display: per-cell red-corner triangle
(Excel-style) plus title-attribute tooltip on hover. Marker
keyed off data-col-idx + the column's field; survives until
the next edit on that cell or the next paint() cycle.
- beforeunload safety net: any rows with drafts at unload time
get one fire-and-forget save attempt. Modern browsers limit
what beforeunload can do; a follow-up could add fetch's
keepalive flag for a more reliable last-shot.
UI surfaces:
- Per-row state classes drive a left-border swatch in the first
cell:
--dirty subtle blue (uncommitted changes)
--saving muted grey (PUT in flight)
--queued warm yellow (outbox accepted)
--invalid orange (server 422)
--stale warning amber (server 412 — also tints row bg)
--errored red (other failure — also tints row bg)
These re-apply across re-paints via save.markAllDirtyRows()
called from main.js's paint() hook (innerHTML='' wipes them).
- #table-status doubles as the conflict prompt host. When a row
goes stale, the bar shows
"This row was changed by someone else. [Use mine] [Reload] [×]"
and the row-id it's bound to is stored on data-row-id so a
successful reload of that row dismisses the prompt.
Outbox (downstream client) interaction:
The cache layer's PUT-replay queue intercepts saves transparently.
On local network failure the cache returns 202 with
X-ZDDC-Cache: queued; we treat 202 as "succeeded for now" —
drafts clear (the outbox owns them and will replay), but the
row stays marked --queued so the user knows the write hasn't
reached upstream yet. When the cache replays and gets a
real 200/201/412/etc., the row state will reflect that on next
read (next paint cycle / page refresh).
Tests (4 new Phase 3 specs, total 31 in tests/tables.spec.js):
- row-blur fires PUT with merged drafts + If-Match. Edit a
cell in row 0, Enter (commits + moves to row 1). Verifies
PUT went out with the right URL, the merged YAML body
contains the new value AND the unchanged fields, and the
If-Match header carries the original ETag.
- 412 conflict marks row stale + shows status prompt. Verifies
the row gains the stale class, the status bar appears with
both [Use mine] and [Reload] buttons, AND the draft is
preserved (never silently dropped on conflict).
- 422 validation errors mark cells invalid. Verifies multiple
field errors → multiple red-corner cells.
- Reload button drops drafts and refreshes. Verifies the bar
hides and drafts clear after a successful reload GET.
Setup: a small page.route helper intercepts http://test.local/*
PUTs and GETs, lets each test queue the next response via
window.__nextResponse, and captures requests at
window.__capturedRequests for inspection. Test fixtures use
absolute http URLs in row.yamlUrl so the route catches them.

Replaces the always-text-input cell editor with a per-property
widget factory keyed off the row's JSON Schema (form.yaml). The
table view now picks the right editor for each cell automatically:
strings get text inputs, enums get dropdowns, integers get number
inputs with min/max, dates get date pickers, booleans get
checkboxes, multi-select arrays get a multi-select. Cells whose
schema is a complex type (nested object, generic array, oneOf /
anyOf / allOf) can't be inline-edited and punt to the row's
form-mode editor on Enter / double-click.
Schema discovery:
context.js walkServer fetches <currentdir>/form.yaml as a
companion to <currentdir>/table.yaml — same file the form-mode
renderer already loads, just from the table view's perspective.
Best-effort: a directory with table.yaml but no form.yaml still
renders as a sortable/filterable table; cells just fall back to
plain text inputs without per-property hints. The schema is
exposed as ctx.rowSchema and consumed by the editor's
propertySchemaFor() helper, which walks dot-separated field
names through schema.properties to locate each column's
property schema.
Editor factory (editor.js):
- propertySchemaFor(col) — schema lookup keyed by col.field.
- isComplexSchema(s) — true for nested object, generic array,
oneOf/anyOf/allOf. Multi-select-friendly arrays
(string-enum + uniqueItems) are NOT complex; they get an
inline multi-select widget.
- makeWidget(propSchema, col, initialValue) — dispatches to one
of the widget builders below based on schema type / format /
enum + column-spec hints (col.format / col.enum) for tables
without a form.yaml.
Widget builders, each returning {element, getValue, focus}:
- widgetText — plain <input type=text>, default fallback.
- widgetTextarea — for string with maxLength > 200 (long
narrative fields).
- widgetTyped(type) — typed inputs the browser can help validate;
used for date / date-time / email.
- widgetNumber — <input type=number> with min/max/step
derived from schema.minimum/maximum/
multipleOf. Integer schemas force step=1.
getValue returns Number, not string, so
the draft buffer holds the right type for
JSON serialization later.
- widgetCheckbox — <input type=checkbox>; getValue returns
bool. initial value coerces from "true"/
true string-or-bool.
- widgetSelect — <select> with empty placeholder + one
option per enum choice; getValue returns
the chosen string or null.
- widgetMultiSelect — <select multiple> with size = min(6, N);
getValue returns the array of selected
values (preserves order in the option list).
Complex-type cells:
isComplexSchema(propSchema) → enterEdit calls navigateToRowForm,
which routes to row.url (already the <id>.yaml.html re-edit URL
the row tracker holds). Phase 5 may swap this for an inline
side-panel mount of form-mode in the same bundle, but the
current navigate-out path delivers the same eventual UX without
needing the side-panel scaffolding.
Type-aware draft equality:
The pre-Phase-2 commit treated every value as a string and
compared via String() equality, which would mark any number-
column edit dirty even when the user re-typed the same number.
The new sameValue() helper handles bool/object via JSON-string
equality and falls back to loose string compare so 42 == "42"
isn't a false dirty. Drafts hold typed values (number, bool,
array) instead of all strings, so when Phase 3 wires the row PUT
the body shape matches the JSON Schema the server validates
against without an additional coercion pass.
Tests (tests/tables.spec.js — 7 new specs, total 22 in the
table view, all 27 in the file):
- enum column edits via select dropdown — verifies the empty
placeholder + 3 enum options render and the chosen value
displays back in the cell.
- integer column gives a number input with min/max — verifies
the type/min/max/step attributes derive from the schema, AND
the draft buffer holds typeof === 'number'.
- boolean column gives a checkbox — verifies type=checkbox and
the draft holds true after Space-toggle. (Toggle via Space,
not Playwright's .check() helper, to dodge the click+blur
race a focused-checkbox-inside-grid-cell hits.)
- format:date column gives a date input — verifies type=date
and the existing value pre-populates as YYYY-MM-DD.
- multi-select enum-array column gives a multi-select.
- complex (object) column navigates to the row form on edit —
verifies no inline editor mounts AND the navigate seam
receives the row's URL.
- no rowSchema → falls back to plain text editor — verifies the
best-effort behavior for directories with only table.yaml.
Bundle size: 124 KB → 127 KB (+3 KB for the factory + widget
builders).

First step toward the Excel-like editable-table the user asked for.
Architecture decisions in this phase came from a focused research
pass over Notion / Airtable / AG Grid / Handsontable / Glide / W3C
ARIA APG; the design notes are in this commit's predecessor as a
research synthesis. Five phases planned; this is phase 1 of 5 and
ships the cell-selection + keyboard-navigation + per-cell editor
mount-on-demand foundation. Edits in this phase live in a client-
side draft buffer only; row-level save + ETag conflict UX is
phase 3.
Scope:
- ARIA grid pattern verbatim (W3C WAI-ARIA APG): role=grid on the
table, role=row on rows, role=gridcell on cells, roving
tabindex (only one cell carries tabindex=0; arrows move it).
This makes the grid one tab stop in the page tab order — the
documented spreadsheet UX, and also the basis for screen-reader
correctness.
- Click selects a cell. Arrow keys move selection. Tab and
Shift-Tab move with row-wrap. Home / End jump within row;
Ctrl/Cmd+Home / End jump to grid corners. Enter, F2, double-
click, or any printable character all enter edit mode. In edit
mode: Enter commits and moves down (Excel convention), Tab
commits and moves right (with row-wrap), Escape cancels and
restores the prior value, blur commits.
- Mount-on-demand cell editor: one <input> at a time is
instantiated inside the selected cell. Survives 1000-row tables
without the focus-ring churn an always-editable design would
hit, and lets Phase 2 swap the input for schema-driven widgets
(number / date / select / etc.) without restructuring.
- Draft buffer at app.state.drafts keyed by row id (the row's
re-edit URL — stable across sort and filter). When a cell
commits with a value different from row.data, the draft entry
is set; render reads from the draft via effectiveCellValue() so
the visible cell content reflects unsaved edits. No-op edits
(commit returns the original value) clear any pending draft.
- Selection survives re-paints. Sort / filter / spec changes
trigger a re-render; the editor's setSelected at end of paint()
clamps to new bounds and rebinds tabindex. The user's cell
doesn't disappear when they sort the column they're editing.
- Numeric coercion fast-path: cells whose column declares
format=number/integer coerce the input string to Number on
commit. Phase 2 will generalize this to schema-driven coercion
for date, boolean, enum, etc.
UX consequence — single-click semantics change:
The pre-existing row-click-navigates-to-form-edit behavior is
gone. Single click now selects a cell (spreadsheet-native). The
"open this row in the form editor" affordance moves to phase 2
(an explicit "Edit…" button or an icon column). The row-click-
navigation tests in tests/tables.spec.js are replaced with seven
new tests covering the editor lifecycle.
What this phase does NOT do (and which phases own it):
- Phase 2: schema-driven editor widgets (right input type per
column). Server-side validation 422 → red-corner marks. Complex
types (object, generic array, oneOf) get an "Edit…" button that
opens the side-panel form-render mode the unified bundle
already ships.
- Phase 3: row-level save on row-blur via PUT + If-Match. Stale-
row badge with "Use mine" / "Reload" on 412. Outbox carries the
offline path transparently via the existing source.js layer.
- Phase 4: copy/paste from Excel/Sheets via TSV parser, spill-
from-anchor or fill-all into a selection range.
- Phase 5: undo (linear command stack, Ctrl+Z, session-local) and
multi-cell ops (range select, bulk delete, Ctrl+D / Ctrl+R fill).
Tests (tests/tables.spec.js, all 15 pass):
- clicking a cell selects it (replaces the old row-click-navigates
test; verifies single-click does NOT navigate)
- arrow keys move cell selection
- Tab and Shift-Tab traverse cells with row-wrap
- Enter enters edit mode; Enter commits and moves down (verifies
draft is applied to visible cell + selection moves)
- Escape cancels edit, restoring prior value (verifies no-op on
draft buffer)
- typing a printable char enters edit and replaces the value
- double-click also enters edit mode
- non-editable rows still get the readonly class (cosmetic guard
for an existing convention; phase 3 will gate write submission)
Files:
- tables/js/editor.js (new) — selection + keyboard handling +
edit-mode lifecycle + draft buffer.
- tables/js/app.js — state.selected / state.editing / state.drafts
fields.
- tables/js/render.js — ARIA roles + editor.attachToCell wiring;
cells render via editor.effectiveCellValue so drafts show.
- tables/js/main.js — paint()-end editor.attachToTable +
setSelected restore.
- tables/css/table.css — selected-cell focus ring (outline,
doesn't shift surrounding cells); cell-input bare-inside-cell
styling.
- tables/build.sh — editor.js in the concat list.
- zddc/internal/handler/tables.html — regenerated bundle.
Bundle size: 117 KB → 124 KB (+7 KB for editor.js + ARIA + draft
machinery). Well within the budget the library survey identified
(Tabulator would have been +100 KB; SlickGrid +34 KB; custom is
+7 KB and we keep the no-third-party-deps invariant).

Two intertwined refactors that share too many files to split cleanly.
Both are described separately below.
PART 1 — in-dir convention for table+form spec files
Old layout had the spec at the parent and rows in a child:
archive/<party>/
mdl.table.yaml spec
mdl.form.yaml row-edit form
mdl/ rows-dir
row-001.yaml ...
URLs were /<dir>/mdl.table.html and /<dir>/mdl.form.html. Copying
mdl/ elsewhere lost the spec and form because they lived next door.
New layout collapses everything into the rows-dir:
archive/<party>/mdl/ self-contained
table.yaml spec
form.yaml row-edit form
row-001.yaml ... rows
URLs become /<dir>/mdl/table.html and /<dir>/mdl/form.html. The
"copying-the-folder-takes-everything" property the user asked for
falls out by construction; the row-edit URL /<dir>/<id>.yaml.html
keeps the same shape (spec is now in the same dir, not the
grandparent).
Server changes:
- internal/handler/tablehandler.go RecognizeTableRequest fires on
/<dir>/table.html when <dir>/table.yaml exists. The .zddc.tables
alias map is gone — pure presence-based discovery now matches
the form system's existing convention. Default-MDL fallback at
archive/<party>/mdl/ stays for the virgin-archive case (the
rows-dir need not exist on disk; the URL renders fully virtually).
- internal/handler/formhandler.go RecognizeFormRequest fires on
/<dir>/form.html and /<dir>/<id>.yaml.html with spec at
<dir>/form.yaml. specEligible accepts on-disk files OR the
default-MDL virtual path so an empty mdl/ dir still surfaces the
add-row form.
- internal/handler/tablehandler.go IsDefaultMdlSpec moves to
serving archive/<party>/mdl/{table,form}.yaml (5 segments after
ZDDC_ROOT). New isAtArchivePartyMdlLevel predicate; new
isAtArchivePartyMdlDir for directory-based recognition. New
IsDefaultMdlSpecAbs accessor for callers that hold an abs path
rather than a URL (formhandler).
- internal/handler/formhandler.go loadFormSpec(fsRoot, path) falls
back to embedded default-MDL bytes when os.ReadFile returns
NotExist AND the path matches the archive-party-mdl shape. Three
call sites updated to pass cfg.Root.
- internal/handler/formhandler.go serveFormCreate writes
submissions to filepath.Dir(req.SpecPath) — the spec, the form,
and rows all live in one directory. The submissionsDir creation
is idempotent (MkdirAll); cascade falls back one level for ACL
evaluation when the dir hasn't been materialized yet.
- internal/handler/tablehandler.go tableRowsRedirect now points at
/<dir>/table.html (was /<dir>.table.html) when the directory
request maps to a recognized table.
- cmd/zddc-server/main.go dispatch synth flips from
urlPath + ".table.html" to urlPath + "/table.html" for the
no-trailing-slash → tables-app routing.
- internal/apps/availability.go DefaultAppAt comment clarified
that the dir at archive/<party>/mdl/ IS the table (not a child).
Client changes:
- tables/js/context.js walkServer fetches <currentdir>/table.yaml
directly — no .zddc walk for table declarations. Rows are every
*.yaml in current dir EXCLUDING table.yaml and form.yaml. The
.zddc fetch-for-aliases is gated on file:// (online mode 404s
on .zddc reads via the dispatcher's reserve guard, so skipping
the request avoids browser console noise).
- tables/js/main.js add-row button links to relative form.html
(same dir).
- tables/js/render.js + filters.js: every column's autofilter is
uniformly a text-contains input, even enum columns — keeps the
filter row visually consistent and doesn't constrain users to
the enum vocabulary.
PART 2 — unified table+form HTML bundle
The form-render and table-render code paths share field schemas,
the cell editor for excel-mode IS a form widget, and the form
system's POST-back / validation already exists. Combining the two
HTMLs eliminates duplicating jsyaml/jsonschema/theme/source-
detection/.zddc-parsing across two single-file tools.
- tables/template.html grows two top-level mode containers:
#table-mode (toolbar + sortable table) and #form-mode (form +
submit button). Both hidden at parse time; the dispatcher
unhides one. The shared #form-context placeholder was added
here so the server's existing injectFormContext target
resolves.
- tables/js/mode.js (new) sets window.zddcMode synchronously
based on URL pattern: /form.html or /<id>.yaml.html → form,
/table.html → table, else inline-context fallback for
file:// (whichever context blob is non-empty wins). Unhides
the matching container at DOMContentLoaded.
- tables/js/main.js init() and form/js/main.js boot() each guard
early when mode isn't theirs. Both apps live on different
globals (window.tablesApp vs window.formApp) so module
registration doesn't collide.
- form/js/main.js title write falls back from #form-title to
#table-title (the unified bundle's shared header element)
when the dedicated id isn't present.
- tables/build.sh concatenates form modules (widgets, render,
object, array, errors, post, serialize, util) and form CSS.
No new external deps. Bundle grows from ~95KB to ~120KB.
- internal/handler/formhandler.go drops the //go:embed form.html
directive; serveFormRender now writes embeddedTablesHTML via
a small formRenderHTML() accessor (var declared in
tablehandler.go, same package). The embedded form.html file
is removed.
- build script: cp form/dist/form.html → internal/handler/form.html
step is gone (file no longer exists in the source tree). cp
tables/dist/tables.html → internal/handler/tables.html now
runs unconditionally rather than only on beta/stable cuts —
the renderer is a fixed binary component and dev iteration
needs the embedded copy refreshed every build. Channel-cascaded
apps (internal/apps/embedded/) stay channel-gated as before.
- form/dist/form.html still builds for standalone offline-only
use (downloadable from /releases/), but no longer goes into
the binary.
Tests:
- internal/handler/tablehandler_test.go and formhandler_test.go
rewritten for the in-dir layout. New test
TestRecognizeFormRequest_DefaultMdlAtArchiveParty covers
empty-form, create POST, re-edit row, and the negative cases
(Working/, non-mdl name) where the fallback must NOT fire.
- internal/handler/directory_test.go updated for the new
/<dir>/table.html redirect target.
- cmd/zddc-server/main_test.go TestDispatchSlashRouting Location
expectation updated.
- tests/form-safety.spec.js loads tables/dist/tables.html
(named form.html in the temp dir to trigger form-mode in the
dispatcher) so it tests the same bytes the server returns.
Title-element selector switches to #table-title.
- tests/tables.spec.js updates the status-filter test for the
uniform text-input filter.
Docs:
- AGENTS.md form-data system rewrites the URL conventions and
storage layout for in-dir; gains a Tables system section
parallel to forms describing the self-contained-directory
property; subfolder rules ("one table per folder by
construction; subfolders allowed and silently ignored as rows
— legitimate uses: nested sub-tables, per-row attachments,
drafts, future history sidecars") so we don't re-derive this.
Not included (deferred):
- ACL gating on cell-level writes — not relevant until Phase 3.
- Editable cells UI — separate commit (Phase 1).

Sub-threshold finding from a focused security review of the CI URL
work — defense-in-depth even though it sits inside the documented
"trust upstream" boundary.
The mirror walker's purgeOrphans deletes local files that aren't in
the upstream's listing. It walked a dirPath built recursively from
upstream-supplied entry names and called os.Remove on the resolved
local path with no containment check. A hostile or compromised
upstream returning ".." in a directory listing could steer the
walker out of cache.root and into the parent — deleting whatever
matches the upstream's "expected to be there" filter in the wrong
directory.
A healthy master never produces such entries (listing.FromDirEntries
filters dot-prefix names), so the bug only fires under an actively
malicious or MITM'd upstream — confidence stayed below the report
threshold. But the fix is small and the cost of being wrong is real
deletion of files outside the cache, so it's worth doing.
Two layers:
1. walker.go walkDir filters upstream listing entries with name ==
"" / "." / ".." or containing "/" / "\" before recursing. Logs
a WARN with the dropped name so an operator can see if their
upstream is misbehaving.
2. purgeOrphans verifies the resolved localDir is contained under
s.cache.root (HasPrefix(root + sep) || == root) before
ReadDir+Remove. Logs a WARN and bails on mismatch.
Either layer alone would fix the original vector; both together
match the defense-in-depth pattern cachePathFor already follows for
single-file writes (line 506).
New TestWalker_HostileUpstreamCannotEscapeCacheRoot constructs a
fake upstream that returns a "../" entry in its listing, places a
sentinel file in the parent of cache.root, runs a mirror walk, and
asserts the sentinel survives. Both filter and containment guard
fire; the sentinel stays put.
Existing mirror tests unchanged — the filter only drops names that
shouldn't appear in healthy listings.

URLs are now case-insensitive against the on-disk casing under
ZDDC_ROOT, with a lowercase-wins tiebreak when sibling case variants
exist. File and folder names preserve case on disk — the change is a
pure URL→FS-name mapping; nothing renames anything.
internal/fs/resolve.go ResolveCanonical walks segments left-to-right
under fsRoot. Per segment: try lowercase first (canonical / cheap
lstat fast-path), then exact-case, then readdir+CI scan with the
all-lowercase variant winning the tiebreak. Walk stops at the first
segment that doesn't exist on disk so virtual prefixes (.archive,
.profile, .tokens, .auth) and 404 paths flow through with their tail
preserved verbatim. Path-escape safety check on the resolved abs
path matches the existing safeJoin pattern.
Wired in at the top of cmd/zddc-server/main.go dispatch(), which
rewrites r.URL.Path before any handler runs. Downstream handlers
(plus their existing safeJoin calls and the cascade walker) pick up
canonical case automatically — no per-handler changes. The ACL
cascade benefits from this for free since EffectivePolicy is keyed
by the now-canonical absolute path.
internal/handler/middleware.go AccessLogMiddleware snapshots the
as-typed URL path before the rewrite. The audit log's `path` field
records what the client actually sent; a `resolved_path` field is
added only when canonicalization changed it. Operators reading the
log can see both the raw request and what was served.
Lowercase as the project-wide canonical convention is already
honoured by the auto-created folders in internal/zddc/ensure.go
(working/, staging/, archive/<party>/incoming/) and the server's
own state dirs (_app/, .zddc.d/tokens/, .zddc.d/outbox/,
.zddc.d/logs/). Operators who drop a Mixed-Case-Folder/ on disk
keep that casing — the resolver finds it via the readdir tier.
Performance: the lowercase-first lstat is one syscall on the hot
path. Only mismatches (mixed-case URL where on-disk is also
mixed-case) pay the readdir+EqualFold scan, and Linux page-caches
small-dir readdirs aggressively. Apache mod_speling uses the same
"try then fallback" pattern.
Tests:
- internal/fs/resolve_test.go — 9 unit tests: exact-case,
mixed-case-URL-with-lowercase-on-disk, mixed-case-URL-with-
mixed-case-on-disk, both-cases-exist-lowercase-wins, nonexistent
segment preserves remainder, file-segment terminates walk, escape
rejection, trailing-slash normalization, root.
- cmd/zddc-server/main_test.go TestDispatchCaseInsensitiveURL —
end-to-end through the dispatcher with sibling Archive/ and
archive/ on disk; all four URL casings of the same path serve the
lowercase variant's content (proves the tiebreak fires through
every layer).
- Full Go suite green.
Docs: AGENTS.md gains a "URL handling" subsection in the
zddc-server section; ARCHITECTURE.md security-model table gains a
"URL canonicalization" row.
Out of scope (separate decisions, can revisit if needed):
- ACL glob CI-matching. If .zddc rules use mixed-case URL globs,
they won't match the canonical lowercase URL. Workable today by
writing rules in lowercase. Touches a different package.
- Redirect-to-canonical (303). Server serves under whichever case
the client used; canonicalization is internal. Could 301 to
canonical for SEO/bookmark hygiene as a follow-up.
- Client-mode (proxy/cache). Only master mode is wired so far.
Cache-handler CI lives in internal/cache/cache.go cachePathFor
and is a separate code path.

A focused security review of phases 1-4 surfaced one MEDIUM finding
(confidence 9/10): in client mode (--upstream set) the cache layer
forwards the configured bearer to upstream on every incoming request
without authenticating the local caller, AND --addr defaulted to
:8443 (all interfaces). Together those mean a CLI user running
`zddc-server --upstream https://master --bearer-file ~/token` on a
laptop on hotel/cafe Wi-Fi exposes an open-proxy confused-deputy:
any attacker on the same L2 connects to https://<laptop-ip>:8443,
accepts the self-signed cert, issues GETs (or PUTs/DELETEs that
queue in the outbox), and the cache laundries each request through
upstream with the engineer's bearer. The full cached subtree leaks.
Two layers of defense in config.Load:
1. Loopback default in client mode. When cfg.Upstream is set and
neither --addr nor ZDDC_ADDR was passed explicitly, --addr
downgrades to "127.0.0.1:8443" (vs ":8443" in master mode). CLI
users on a laptop get safe-by-default. Operators who want a
non-loopback bind opt in explicitly.
2. Refuse non-loopback bind + bearer-file without acknowledgement.
When cfg.Upstream is set, BearerFile is non-empty, the chosen
addr is non-loopback, AND --insecure-direct is not set, the load
fails with an error that names the bind, the threat (open-proxy
confused-deputy laundering bearer credentials), and the
acknowledgement flag. The helm zddc-server-cache/ chart already
sets ZDDC_INSECURE_DIRECT=1 and relies on Kubernetes-namespaced
pod networking for the gating, so the chart path is unaffected.
The guard is bearer-file-conditional because proxy mode without a
bearer doesn't have a credential to launder, and refusing it
would needlessly block proxy-without-auth deployments.
Tests in internal/config/config_test.go lock down all four cases:
- --upstream with no explicit --addr → 127.0.0.1:8443
- --upstream + non-loopback --addr + --bearer-file (no IDirect) → refuse
- --upstream + non-loopback --addr + --bearer-file + --insecure-direct → ok
- --upstream + non-loopback --addr + NO bearer → ok (no credential to leak)
Doc updates: zddc/README.md client-mode "Flags" section gets a
WARNING block describing the loopback default + insecure-direct
escape hatch. AGENTS.md ZDDC_UPSTREAM row mentions the addr
downgrade. ARCHITECTURE.md gains a "Confused-deputy guard at
startup" subsection under "Master + proxy/cache/mirror" with the
two-layer defense rationale. helm/zddc-server-cache/values.yaml.example
adds an inline note next to addr: ":8080" explaining why the chart
sets ZDDC_INSECURE_DIRECT=1 and what the consequence is of removing
either side of the gating.
Master mode is unaffected — the client-mode validation block is
gated by `if cfg.Upstream != ""`. All existing tests pass.

Phase 3 + 4 live two-instance smoke tests against the synthetic
~/zddc-test-data fixture surfaced three real bugs that the unit
tests missed. All three are fixed in this commit.
1. walker: filenames with spaces/parens land on disk percent-encoded
walkSubtree was passing the URL-encoded child URL (built via
url.PathEscape) to fetchFileIfNeeded → cachePathFor, so a file
named "Foo (IFI) - Bar.md" landed at <root>/.../Foo%20%28IFI%29
%20-%20Bar.md on disk. Then purgeOrphans iterated os.ReadDir
(which sees the encoded names) and compared against upstreamNames
(decoded names from the listing JSON). Every fetched file was
classified as an orphan and immediately deleted: a 180-file walk
produced "fetched=180 purged=111" with only 70 files remaining.
Fix: walker now maintains two parallel path strings — dirURL
(URL-encoded for HTTP requests) and dirPath (decoded for disk
keys). fetchFileIfNeeded, fetchListing, persistOnly, and
purgeOrphans all take the decoded path. listingCachePathFor
gets dirPath too. Smoke confirmed: dirs=29 files=180 fetched=179
purged=0 (one file already cached from the user's GET that
triggered the walk).
2. outbox: replay loop sleeps 5min after eager startup pass
RunReplayLoop's idle-poll interval is 5min. After the eager
startup pass with 0 entries, the loop sleeps 5min — even if a
PUT-while-offline arrives 1 second later, replay won't fire for
~5 min. The cache returned 202 promptly but the queued write sat
on disk until either a 5min nap elapsed or another PUT happened.
Fix: Outbox gains a wake chan (buffered=1, drop-on-full).
Enqueue posts to it after writing meta.json. RunReplayLoop selects
on wake alongside the timer, so a new offline write triggers an
immediate replay attempt. Smoke confirmed: PUT queued at T+0,
master back at T+3, replay completes at T+3 (was previously a
30s wait through the timer-based poll).
3. master: PUT/DELETE didn't honor If-Unmodified-Since
The cache's outbox sends If-Unmodified-Since: <cached-mtime> on
replay so the master can reject conflicting writes with 412. The
master's checkIfMatch only evaluated If-Match (ETag-based), so
the cache's mtime-based precondition was silently ignored. Result:
an offline PUT staged before an external mod would clobber the
newer external content on replay — silent data loss in the exact
scenario the outbox is designed to detect.
Fix: checkIfMatch now also evaluates If-Unmodified-Since per
RFC 7232 §3.4, returning 412 when the file's current mtime is
strictly later than the header value (1-second resolution to
match HTTP-Date precision). Smoke confirmed: cache GET → external
mod via direct file write → cache offline PUT → master back →
replay sends IUS → master 412 → outbox entry renamed to
<id>.conflict-<RFC3339>/ → master content preserved (the
external mod, not the stale offline write).
Also added an info-level "outbox: replay attempt" log to tryReplay
so an operator watching the cache logs sees the replay loop is
alive even when every entry defers (transport error). Previously
the loop was silent unless a replay actually completed (200) or
conflicted (412).
go vet + go test ./... + go test -race ./internal/{cache,auth,handler}/...
all green. Synthetic ~/zddc-test-data fixture (553 files, 144 PDFs)
exercises the walker against realistic ZDDC filenames including
spaces, parens, and accented characters that the unit tests'
"a.txt" / "b.txt" inputs never hit.

PUT / POST / DELETE in client mode now work end-to-end. Online: the
cache layer forwards to upstream and (on success) drops any cached
entry for the path so the next read fetches fresh. PUT/DELETE include
If-Unmodified-Since derived from the cached file's mtime so the master
can reject conflicting writes with 412 Precondition Failed.
When upstream is unreachable, the request is captured in the outbox
at <root>/.zddc-outbox/<id>/ — directory per queued write, mode 0700,
containing meta.json (method, RawURI, Content-Type, base mtime,
queued-at) and body.bin (request body, capped at 256 MiB). The client
gets 202 Accepted + X-ZDDC-Cache: queued and a JSON envelope.
A background replay loop started by runClient processes the queue:
- 2xx → delete entry; drop cached path so next read fetches fresh
- 412 → rename to <id>.conflict-<RFC3339>/ for manual reconciliation
(body + meta intact for inspection or re-submit)
- 4xx other → drop (retry won't help; logged at WARN)
- 5xx / transport error → leave for next pass
Replay schedule: eager at startup, then 30s while pending falling
back to 5min while idle. Loop honors graceful-shutdown context.
Disabled in --mode=proxy (proxy persists nothing by design — offline
writes return 503 instead of queueing).
Outbox IDs are <unix-nano-base16>-<hex-random> so lex-sort = queue
order; concurrent enqueues never collide. Conflict-rename appends a
4-char random suffix on the unlikely same-second collision.
The local cache is intentionally not updated for offline writes:
until upstream confirms the user reads still see the upstream-cached
version (or 503 if uncached). Trade-off: no "did my queued write
actually win?" ambiguity, at the cost of not seeing one's own
offline edits immediately. Phase 5 will surface .conflict-<ts>/
directories in browse views.
Tests (20 new in outbox_test.go, 5 new in cache_test.go covering
the write path): NewOutbox creates 0700 dir, Enqueue persists meta
+ body, Pending returns lex-sorted entries excluding conflicts,
Replay deletes on 2xx / renames on 412 / leaves on transport error
/ leaves on 5xx / drops on 4xx-other, IUS sent only for PUT/DELETE
with base mtime, query string preserved, ServeHTTP online write
forwards + evicts cache, ServeHTTP offline write queues with 202,
ServeHTTP offline + no outbox returns 503, ServeHTTP PUT sends IUS
from cached mtime, oversize body rejected, IDs lex-sortable,
RunReplayLoop stops on context cancel, concurrent Enqueue 30×
no collisions. Full suite + go vet clean.
Doc updates: zddc/README.md gains a "Writes (online + offline
outbox)" subsection covering both paths and replay outcomes;
"What client mode is NOT, yet" now lists only conflict UI and
multi-tenancy. AGENTS.md client-mode pipeline gains writes +
mirror-mode bullets. ARCHITECTURE.md adds a "Writes: outbox +
offline replay" subsection with the trade-off rationale and the
phase-5-deferred conflict UI hand-off.

--mode mirror layers an access-triggered walker on top of the cache
pipeline. When an incoming request's URL falls under one of the
configured --mirror-subtree paths, the scheduler kicks off a recursive
walk of that subtree iff (a) no walk for that subtree is in flight and
(b) now - last_walk_at >= --mirror-min-interval (default 1h). Walks
run in a goroutine; the user's request never blocks on scheduling.
Why access-triggered: a naive "walk on a fixed timer" would produce
thundering-herd polls on a master from many vendor mirrors most of
which are idle most of the time. Demand-triggering means idle mirrors
generate zero upstream traffic until someone hits them; active
mirrors stay current as a side effect of normal use.
The walk:
1. Recursively fetches JSON listings under the subtree, persisting
each at <dir>/.zddc-listing.json so directory browsing works
offline for walked subtrees.
2. For each file, fires a conditional If-Modified-Since GET (bounded
parallelism; default 4 concurrent) — 304 no-op, 200 overwrites,
403/404 purges the local cache.
3. After enumeration, per-directory orphan purge: local files absent
from upstream's filtered listing are removed (handles upstream
deletes + ACL revocations).
State persists at <root>/.zddc-mirror-state.json as
{subtrees: {<path>: {last_walk_at}}}. In-flight tracking is in-memory
only — a crash mid-walk lets the next access retry without manual
cleanup. Subtree path matching is longest-prefix-wins; "/" is a
catch-all (full mirror, the default when --mode=mirror is set without
explicit --mirror-subtree).
The cache layer also gained directory-listing caching (independent of
mirror mode but enabled by it). Directories are now stored at
<dir>/.zddc-listing.<html|json> sidecars, varied by Accept header.
Hit/miss/offline semantics mirror the file pipeline. Phase 2's
limitation that directories always proxied live (no offline browse)
is now resolved for any directory the user has visited or that mirror
mode has walked.
Mirror scope falls out of auth: the walker uses the local instance's
bearer, so it sees exactly what the user can see at upstream. Admin
bearer → full mirror; vendor bearer → vendor's permitted subtree;
no code distinguishes the cases.
New flags (also as ZDDC_* env vars), ignored when --mode != mirror:
- --mirror-subtree <csv> — repeatable subtrees (comma-separated);
empty + --mode=mirror = "/" (full mirror)
- --mirror-min-interval <duration> — default 1h
Tests (15 new in walker_test.go, 3 new in cache_test.go): subtree
normalization, longest-prefix matching, root-as-catch-all, walk
fetches all files in scope, out-of-scope URLs are no-op, rate-
limiting prevents double-walks within min-interval, walks re-fire
after interval elapses, orphan purge removes local-only files,
state file survives restart, concurrent triggers don't double-walk,
end-to-end ServeHTTP-kicks-mirror-on-access, listing format varies
by Accept, listing offline serves stale, persisted state atomic
write + corrupt-input handling. Full suite + go vet clean.
Doc updates: zddc/README.md flags table gains the two new entries
plus a "Mirror mode (access-triggered subtree walker)" subsection
with trigger semantics and properties; the "What client mode is NOT,
yet" list shrinks accordingly. AGENTS.md env-var table gains the
two new entries. ARCHITECTURE.md "Master + proxy/cache/mirror"
section now documents the walker scheduler / walk algorithm / state
file in a "Mirror walker (access-triggered)" subsection.

zddc-server can now run as a downstream client of another zddc-server.
Set --upstream <url> and the master-side machinery (archive index, apps
server, watcher, OPA decider, ACL middleware, token store) is bypassed
entirely; cmd/zddc-server/main.go short-circuits to runClient(cfg)
which uses zddc/internal/cache/Cache as the entire request handler.
Three modes via --mode <proxy|cache|mirror>:
- proxy: forward upstream live, no disk persistence
- cache (default): persist responses on access; subsequent hits serve
from disk + background If-Modified-Since revalidate
- mirror: accepted but currently behaves like cache; the access-
triggered walker lands in phase 3
Cache directory layout is intentionally a normal ZDDC root: a file
fetched from <master>/foo/bar.txt is stored at <root>/foo/bar.txt with
no sidecar metadata. The local file's mtime is set to the upstream's
Last-Modified header so revalidation reflects the master's notion of
file age, not local fetch time. Running zddc-server --root <cache-dir>
without --upstream serves the cached files as a plain master — useful
for portable offline snapshots. A small .zddc-upstream marker is
written once on first persist for provenance.
Pipeline (GET/HEAD only — writes deferred):
- Hit → http.ServeContent serves directly (range-aware, 304-aware) +
background revalidate (304 no-op, 200 overwrite, 403/404 purge)
- Miss → forward to upstream with the configured bearer; tee response
body to client + tmp-file atomically renamed into the cache
- Network error + cached → serve stale + X-ZDDC-Cache: offline
- Network error + no cache → 503 + X-ZDDC-Cache: offline
- Directories always proxy live (no listing cache yet — phase 3)
- Cache-Control: no-store / private and non-200 responses bypass cache
Range requests work end-to-end (Range/If-Range headers forwarded on
miss; http.ServeContent handles them natively on hit). Hop-by-hop
headers per RFC 7230 §6.1 are dropped from forwarded responses.
New flags (also as ZDDC_* env vars), all ignored when --upstream is
empty (so master deployments are untouched):
- --upstream <url>
- --mode proxy|cache|mirror (default cache)
- --bearer-file <path> (0600 file with the master-issued token)
- --skip-tls-verify (separate from --no-auth; for self-signed dev)
Validation: --upstream must be http(s)://...; trailing / is trimmed.
Mode validated to one of the three known values. The startup
no-root-.zddc check is skipped in client mode (the cache directory
starts empty by design). The plain-HTTP-on-non-loopback check is also
skipped (the local instance never reads the email header to decide
anything; auth is forwarded to upstream as a Bearer).
Tests: zddc/internal/cache/cache_test.go runs httptest.NewServer as
the upstream and covers miss-then-hit, proxy-mode-no-persist,
directory-never-cached, HEAD-no-body, offline-with-cache,
offline-no-cache → 503, bearer forwarding, query-string preservation,
no-store bypass, path-traversal rejection, error-status forwarding,
revalidate-on-403/404/200/304, range-on-hit, concurrent-same-URL,
cache-path boundary cases. 23 new tests, full suite + go vet clean.
Live two-instance smoke verified: master at 127.0.0.1:18443, client
at :18444 with --mode cache, miss→hit→hit transitions work, file
materialises under cache root with parent dirs created, marker file
written once, range-on-hit returns 206, master sees background 304s
on every hit, killing master leaves cached files serving from disk
and never-cached files returning 503 + offline header.
Doc updates: zddc/README.md gains a "Client mode" section with the
modes table, flag reference, pipeline summary, two-instance recipe,
and explicit list of phase-2 limitations; AGENTS.md adds the four
new env vars to the reference table and a "Client mode" subsection
with smoke-test recipe and a pointer to the cache package;
ARCHITECTURE.md adds "Master + proxy/cache/mirror" before "Bearer
token issuance," covering the topology, the persist/warm switches,
the cache-IS-a-ZDDC-root invariant, the request pipeline, and the
v1-out-of-scope multi-tenancy note; CLAUDE.md's zddc/ entry
expanded to mention both deployment shapes so future agents pick it
up by default.

zddc-server now issues its own bearer tokens for non-browser callers
(CLI tools, scripts, downstream proxy/cache/mirror instances). No
external IDP, no JWKS rotation. Self-service flow: sign in via the
browser, visit /.tokens, click "Create token," paste the resulting
plaintext into a 0600 file, and pass --bearer-file <path> to whatever
calls back into the server.
Storage is <ZDDC_ROOT>/.zddc.d/tokens/<sha256-hex>, YAML per token
with email/created/expires/description. Filename is the *hash* of the
plaintext, never the plaintext itself — a leak of the tokens
directory exposes hashes, not credentials. Mode 0600 / 0700, atomic
writes via temp+rename. Already shielded from public serving by the
existing dot-prefix guards in dispatch and fs.ListDirectory.
ACLMiddleware now recognises Authorization: Bearer <token>. On valid
token, sets the request email from the token file and falls through
to the existing ACL chain. On any failure (unknown / expired / store
unavailable / Bearer with no validator), returns 401 — no silent
fallback to anonymous, so a misconfigured client fails loudly.
JSON API at /.api/tokens (GET list, POST create, DELETE /<id> revoke)
backs a small inline HTML self-service page at /.tokens. Users can
only see and revoke their own tokens; cross-user revoke returns 404
to avoid leaking ownership.
--no-auth (ZDDC_NO_AUTH=1) skips ACL enforcement entirely on this
instance. On master: anyone reads everything (dev / trusted-LAN /
public-read deployments). On a downstream proxy/cache/mirror: trust
upstream's filtering, don't re-evaluate ACLs locally. Implemented as
a swap to policy.AllowAllDecider; all existing handlers keep calling
AllowFromChain unchanged. Distinct from --insecure, which only
relaxes the no-root-.zddc startup check. WARN-level startup log when
--no-auth is active so accidental enablement is visible.
33 new tests covering token storage, validation/expiry/revocation,
the JSON API end-to-end, the HTML page, and the middleware-Bearer
integration including the case-insensitive prefix and expired-token
paths. Full suite + go vet clean.
Doc updates: zddc/README.md "Authentication" rewritten to cover both
auth paths and the token UI/API; AGENTS.md gains ZDDC_NO_AUTH and a
"Bearer tokens" subsection flagging the dot-prefix-shielding pre-
condition; ARCHITECTURE.md adds "Bearer token issuance" and
"--no-auth" subsections under "Server security model" with the
hash-as-filename rationale and dispatch-shielding regression-
sensitivity called out; CLAUDE.md adds a one-line summary of the new
auth topology so future agents pick it up by default.

When an HTML GET hits a directory that's the rows-dir of a registered
table — i.e. parent declares `tables: { <name>: ... }` with a valid
spec, OR the default-MDL fallback applies at archive/<party>/mdl/ —
ServeDirectory now 302s to <parent>/<name>.table.html so users land
on the table view instead of a bare browse listing of the row-yaml
files. JSON GETs on the same URL fall through unchanged so the table
client can still enumerate row files.
Detection reuses RecognizeTableRequest: synthesize the equivalent
.table.html URL from the directory request and let the existing
recognizer apply its operator-vs-default-vs-missing-spec rules. No
duplicated validation.
Updates main_test.go's TestDispatchSlashRouting to expect the new
behavior on archive/<party>/mdl/.

Add a virtual-URL alias so the existing form-based .zddc editor is
reachable at the natural directory location (<dir>/.zddc.html) in
addition to the legacy /.profile/zddc/edit?path=<dir> entry. Both
flow through the same renderZddcEditor body — same template, same
gate, same form-posts-to-/.profile/zddc semantics.
Wiring:
- IsZddcEditorRequest(urlPath) reports whether the URL ends with
the .zddc.html leaf (case-fold not needed; .zddc is itself case-
sensitive on disk).
- ServeZddcEditorAtPath strips the leaf, resolves the parent dir,
asserts the dir exists, gates on hasAnyAdminScope, calls the
shared renderer.
- The dispatcher routes IsZddcEditorRequest URLs BEFORE the dot-
prefix segment guard (which would otherwise 404 the .zddc.html
leaf). The route is method-gated GET-only; mutations still go
through PUT/POST/DELETE on <dir>/.zddc via the file API.
Permission model unchanged from the /.profile entry: hasAnyAdminScope
gates visibility of the editor itself; CanEditZddc decides whether
the form is interactive or read-only at the requested directory.
Subtree admins can still inspect ancestor cascade ACLs (intended
since the cascade is what determines their authority).
Test (TestDispatchZddcEditorAtPath): root admin opens project /
working/ / deployment-root editors; non-admin and anonymous both
404; missing directory 404; trailing-segment-after-leaf 404.

URL convention for directories under a project:
- <dir>/ (with trailing slash) → browse (the directory view; same
behaviour as today)
- <dir> (without trailing slash) → the canonical default tool for
that directory's context, served
inline (no 301 hop)
Tool mapping via the new apps.DefaultAppAt(root, dir):
- working/... → mdedit
- staging/... → transmittal
- archive/ → archive
- archive/<party>/ → archive
- archive/<party>/incoming|received|issued/... → archive
- archive/<party>/mdl/... → tables (the per-party MDL grid editor)
Directories outside the canonical layout (project root, scratch
folders) keep the legacy 301-to-trailing-slash redirect since no
default tool fits.
This generalises and replaces the bespoke
"GET archive/<party>/mdl/ → 302 mdl.table.html" redirect added in PR4.
The new dispatcher rule serves the table app inline at the bare-mdl
URL by routing through RecognizeTableRequest with the canonical
.table.html suffix appended; relative fetches resolve identically
because both URLs share the same parent directory.
Tests: TestDefaultAppAt covers all canonical positions plus
case-fold and out-of-tree edges. TestDispatchSlashRouting (replacing
the now-obsolete TestDispatchMdlRedirect) verifies the slash-vs-no-
slash distinction at every canonical folder + non-canonical
fallback.

Address two follow-ups from the security review of feat/zddc-inherit-directive:
1. file.go's Inherit docstring previously claimed "the internal decider
treats it as inherit:true and emits a warning at evaluation time" —
the decider does the first part but the warning was never wired up.
Strike the over-promise; point operators at the cascade tracer
(`/.profile/effective-policy`) which surfaces both `cascade_mode`
and `chain.visible_start` so a fenced configuration that's being
ignored under strict mode is visible.
2. AllowedAtLevel hardcodes ModeDelegated. Safe today (1-level
synthetic chain, no ancestors) but a footgun if anyone migrates
the shim to a real PolicyChain later. Add a `// Deprecated:`
marker pointing at GrantedVerbsAtLevel for fence-aware paths.

Add a new "The inherit: directive" subsection in zddc/README.md
under "Access control: the .zddc cascade" describing the directive's
purpose (vendor-folder reset, regulated subtrees), the four behaviour
points (grants, roles, admins, WORM), the strict-mode refusal under
NIST AC-6, and the tracer's visibility. Cross-link from the "How a
request is evaluated" walkthrough so a reader who's looking up the
core walk can find the fence behaviour without having to scan further.
Update the "Patterns that look secure but aren't" trap #1 (same-level
allow + deny "*@company.com") to recommend inherit: false as the
preferred fix, with a worked-example .zddc snippet alongside the
broken one. The two-level gate-and-reallow pattern remains as a
fallback for federal-track deployments where inherit: is refused.

The cascade tracer's JSON response now carries:
- Top-level `cascade_mode` (string): the active mode (delegated /
strict). Helps reviewers correlate the visible_start with the mode.
- Top-level `chain.visible_start` (int): chain.VisibleStart(leaf, mode)
— the lowest level whose grants the leaf can see, accounting for any
inherit:false fence in delegated mode (always 0 in strict mode).
- Per-level `inherit` (*bool, omitempty): the level's explicit inherit
value, nil when absent. A reviewer can scan the levels and see which
one fences ancestors.
The level's `exists` flag now also fires for `permissions:` and
`inherit:` entries (previously it only checked Allow/Deny/Admins),
so the response correctly reflects modern .zddc files that use the
permissions map.
Test: TestServeProfileEffectivePolicy_InheritFence builds a vendor-
folder layout, asks the tracer about a my-company user, confirms
decision=false, visible_start=1 (fence at /Vendor/), leaf.Inherit=
&false, root.Inherit=nil.

A .zddc may now declare `acl.inherit: false` to fence off ancestor
grants and roles from the descendant subtree — the "complete reset
plus add back" pattern operators want for vendor folders and other
narrowly-scoped subtrees. The cascade walker honors the deepest fence
in [0, toIdx] when evaluating any level at-or-below it, both for
GrantedVerbsAtLevel/EffectiveVerbsRange and for role lookup
(RoleMembers / lookupRoleMembers).
Federal/strict cascade mode IGNORES the fence — required by
NIST AC-6 ("ancestor deny is absolute; no leaf-level override"). So
inherit:false has no effect under strict mode and ancestor grants
remain visible. Operators running the federal Rego preset get the
same behaviour from external policy enforcement.
API surface: ACLRules.Inherit (*bool, nil = unset = inherit-true);
ACLRules.InheritsAncestors() bool; PolicyChain.VisibleStart(toIdx,
mode) int. The mode parameter is now threaded through
GrantedVerbsAtLevel, MatchesPrincipal, MatchingPrincipals,
RoleMembers, and lookupRoleMembers so role resolution is fence-aware.
Tests:
- file_test.go: parser round-trip for absent / true / false inherit
- inherit_test.go: VisibleStart (no fence, fence clamps, nested fences,
strict-mode override), EffectiveVerbs (fence hides ancestor grants,
strict-mode keeps them), RoleMembers (ancestor roles hidden by fence,
local redefinition still works)

Three pieces wire the per-party Master Deliverables List as the default
view at archive/<party>/mdl/:
1. **Dispatcher redirect.** GET (and HEAD) on
<project>/archive/<party>/mdl/ (case-fold on archive and mdl) now
302 → <project>/archive/<party>/mdl.table.html. Non-archive paths
and deeper mdl/ paths fall through unchanged.
2. **Default-spec fallback in RecognizeTableRequest.** When a request
matches archive/<party>/mdl.table.html and no operator-supplied
tables: { mdl: ... } declaration covers it, the handler returns a
recognised request anyway. Operator declarations still win — and a
typo'd declaration pointing at a missing file yields 404 (not a
silent fallback).
3. **Static-file fallback for the spec yaml.** GET archive/<party>/
mdl.table.yaml and archive/<party>/mdl.form.yaml return embedded
default bytes (default-mdl.{table,form}.yaml in the handler package)
when no operator file exists at that path. Operator files always
win because the dispatcher's os.Stat finds them before reaching the
IsDefaultMdlSpec branch.
The defaults use ZDDC vocabulary: tracking, title, discipline, type,
plannedRevision, plannedDate, status (DFT/IFR/IFA/IFC/AFC/AB), owner,
notes. Operators override per-party by writing
archive/<party>/{mdl.table.yaml,mdl.form.yaml} and a tables: { mdl: ... }
entry in the party's .zddc.
Tests:
- 4 dispatcher redirect cases (success, case-fold mdl, case-fold archive,
deeper-path skip, non-archive skip)
- 6 tablehandler cases (default fires at archive/<party>/, operator
override wins, scope check, embedded yaml served, operator yaml wins,
scope check on yaml fallback)

ListDirectory now appends a synthetic <viewer-email>/ entry when the
listed path is exactly <project>/working/ (depth 2, case-fold) and no
real directory there matches the viewer's email under any case.
The entry has IsDir=true and a new Virtual=true flag on
listing.FileInfo (omitempty in JSON so existing clients that don't
know the field continue to render it as a regular folder). A first
write to that path materialises a real folder via the existing
auto-own pipeline (EnsureCanonicalAncestors → WriteAutoOwnZddc),
after which subsequent listings drop the synthetic entry naturally.
Anonymous viewers, listings outside working/, and listings inside a
deeper working/ subdirectory all skip the synthetic entry.
Six tests cover: appears-when-missing, suppressed-when-real-exists
(case-fold), anonymous-no-entry, staging/-no-entry, deep-working-no-
entry, and pre-existing-PascalCase-Working/ still triggers it.

When a folder is created under <project>/staging/ whose name parses as a
ZDDC transmittal folder (YYYY-MM-DD_<tracking> (<status>) - <title>) and
whose tracking number contains -TRN- or -SUB-, also create the same-
named folder under <project>/working/ as a drafting space for staff.
The mirror is one-way and one-shot: created at staging-mkdir time only.
Renames and deletions of either side are not propagated. The
transmittal client orchestrates cleanup at issue time (move files to
archive/<recipient>/issued/, then delete both staging and working
siblings) — the server stays out of that decision.
-MDL- tracking deliberately skips the mirror; MDL deliverables live in
archive/<party>/mdl/ rows, not via the working↔staging pairing.
Implementation: mirrorStagingToWorking() in fileapi.go, called after a
successful serveFileMkdir. EnsureCanonicalAncestors handles working/'s
own auto-own .zddc; the mirror folder gets its own creator-grant on top.
Six new tests cover -TRN-/-SUB- mirror, -MDL- skip, non-transmittal
name skip, deep-path skip, and idempotency over a pre-existing sibling.

New helper pair:
- ResolveCanonicalPath(fsRoot, target) — case-fold path resolution, no side effects
- EnsureCanonicalAncestors(fsRoot, target, email…) — case-fold + MkdirAll + auto-own .zddc seeding
For each canonical position along the requested path the helpers
substitute on-disk casing (so /Project/working/foo lands in an existing
Working/ rather than a new sibling) and materialise missing
working/staging/archive/<party>/{mdl,incoming,received,issued}/ folders.
working/, staging/, and archive/<party>/incoming/ get a creator-owned
.zddc seeded automatically; received/, issued/, and mdl/ are created
without auto-own (WORM and data-store concerns respectively).
reviewing/ is rejected — purely virtual, never on disk.
Wired into the file API:
- serveFilePut — resolve before auth, ensure after auth
- serveFileMkdir — resolve before auth, ensure after auth, with
two auto-own checks (target-is-canonical OR
parent-is-canonical)
- serveFileMove (POST) — resolve src+dst, ensure dst before rename so
a move from working/<draft> →
archive/<recipient>/issued/<draft> creates
the per-party folders on the way in
7 new unit tests in zddc/internal/zddc/ensure_test.go cover lazy
creation, case-fold reuse, per-party incoming auto-own, WORM no-auto-own,
empty-principal skip, reviewing rejection, and traversal rejection.

The transmittal-folder grammar was duplicated as a private regex inside
the archive package. Replace the local regex with calls to the shared
parser in zddc/internal/zddc/folder.go so the grammar lives in one
place and the upcoming staging→working mirror logic can reuse it.

BREAKING CHANGE. Project-level Issued/Received/Incoming folders no
longer carry special semantics. WORM enforcement and auto-ownership
move to the per-party canonical layout:
- WORM mask now triggers on archive/<party>/received/ and
archive/<party>/issued/ (any case, any party)
- Auto-own .zddc writes on first mkdir under working/, staging/,
or archive/<party>/incoming/ (any case)
Predicate API:
- IsAutoOwnPath(parentDir, fsRoot) — replaces IsAutoOwnParent(name)
- IsWormPath(requestPath) — same name, new pattern
- WormFolderLevelIndex unchanged signature, new pattern
Legacy SpecialFolderNames / AutoOwnFolderNames / WormFolderNames /
IsAutoOwnParent are deleted (no Deprecated: stubs — early-development
project, no back-compat to preserve).
Tool availability (apps/availability.go) is case-fold throughout:
- mdedit: descendants of working/
- transmittal: descendants of staging/
- classifier: descendants of working/, staging/, or
archive/<party>/incoming/
Working/, WORKING/, working/ all match identically.
Test fixtures rewritten:
- special_test.go: covers IsAutoOwnPath / IsWormPath /
WormFolderLevelIndex / ResolveCanonical / canonical lists
- availability_test.go: per-party rules, case-fold scenarios
- fileapi_test.go: rolePermissionsTestSetup now seeds
Project-X/archive/Acme/{incoming,issued,received}/ rather than
Vendor/{Incoming,Issued,Received}/ at the project root

Pure refactor. The mkdir post-hook in handler/fileapi.go duplicated
zddc-package types; lifting the body into the package itself lets the
upcoming EnsureCanonicalAncestors helper share it without re-exposing
the file API's internals.
No behaviour change. The grant shape (creator email → rwcda + CreatedBy
audit field) and the atomic-write path through zddc.WriteFile are
unchanged.

Introduce the lowercase canonical folder model that the new auto-create
feature will key off:
- ProjectRootFolders = [archive, working, staging, reviewing]
- PartyFolders = [mdl, incoming, received, issued]
- AutoOwnCanonicalNames = [working, staging, incoming]
- VirtualOnlyCanonicalNames = [reviewing]
ResolveCanonical(parentDir, logical) does a case-fold lookup against
os.ReadDir(parentDir) so a manually-created Working/ is reused rather
than shadowed by a new working/ sibling.
Pure addition. The existing SpecialFolderNames / AutoOwnFolderNames /
WormFolderNames are kept (now Deprecated:) so dependent packages keep
compiling until the predicate rewrite lands.

Extracts the YYYY-MM-DD_<tracking> (<status>) - <title> grammar into a
reusable parser in the zddc package, and exposes a tracking-type
predicate for -TRN- / -SUB- (case-fold). The transmittal-folder regex
was previously only inside archive/index.go where it captured just the
date; the new ParseTransmittalFolder also returns tracking, status, and
title so handlers can recognise transmittal envelopes for upcoming
staging↔working mirror logic.

The .archive virtual prefix is now project-scoped at exactly one URL
depth: any /<project>/<sub>/.../.archive/... gets a 301 to the
canonical /<project>/.archive/.... The dispatcher does this before
calling the handler; query strings are preserved (the browser handles
the fragment automatically). .archive is also GET/HEAD-only — anything
else returns 405 with Allow: GET, HEAD, ahead of the file API.
Why: offline-built HTML files reference siblings as
"../.archive/<tracking>.html" from arbitrary depths. All of those refs
should converge on a single stable URL per (project, tracking) so
external links and bookmarks don't fork by entry point.
Permissions now follow the resolved file, not .archive itself.
.archive is a virtual surface — it has no on-disk directory and no
.zddc of its own, so gating it as if it did is wrong. Two gates only:
- Resolve: only the per-target file's ACL chain decides. A user
explicitly allowed at one transmittal folder but denied at the
project root can still fetch tracking numbers that resolve there.
Per-target denial returns 404 (not 403) so existence doesn't leak.
- Listing: filter entries by per-target ACL. If the project bucket
has zero indexed entries → 404 (unknown / empty project, indistinguishable
from a probe). If the bucket is non-empty but the caller can read
no entries → 403 (existence-leak guard: don't confirm an inaccessible
project's archive exists). Otherwise → 200 with the filtered subset.
The listing endpoint is now content-negotiated like ServeDirectory:
Accept: text/html serves the embedded `browse` SPA bytes (with the
embedded ETag and X-ZDDC-Source: embedded:browse); Accept:
application/json returns the JSON entry array (with content-hash ETag
and 304 short-circuit). Vary: Accept set on both. The browse SPA's
auto-detect path-fetch then renders the archive entries as a sortable,
filterable flat list at /<project>/.archive/.
ServeArchive's signature is now (cfg, idx, w, r, project, filename) —
the dispatcher hands the normalized project string in directly, so
projectFromContextPath is gone. Old behavior was to derive project
from contextPath inside the handler; with the upstream redirect that's
redundant and the handler's preconditions are simpler.
Tests: archivehandler_test.go rewritten around the new semantics;
added per-target-only resolve, project-root-deny + per-target-allow
rescue, listing 403/404 distinction, JSON/HTML content-negotiation,
and conditional GET. main_test.go gains TestDispatchArchiveRedirect
(deep paths, query preservation, already-canonical no-op) and
TestDispatchArchiveMethodGate (PUT/POST/DELETE → 405).

The fsnotify watcher only sees events the local kernel generates, so on
SMB/CIFS-backed roots (Azure Files) writes from any other client are
invisible — the archive index would silently miss them until pod
restart. Add two backstops:
1. Periodic full re-walk via Index.Rebuild on a configurable interval
(--archive-rescan-interval / ZDDC_ARCHIVE_RESCAN_INTERVAL, default
60s, 0 to disable). Atomically swaps ByProject under the existing
RWMutex; concurrent reads stay safe.
2. Admin-only POST /.profile/reindex that triggers an immediate rebuild
and returns {duration_ms, project_count, tracking_count}, for the
"I just dropped 50 files and don't want to wait" case. Gated by
IsAdmin with the same 404-on-non-admin pattern as the other admin
sub-resources.
Tests: TestRebuild_PicksUpAddsAndDrops covers add+drop semantics and
returned counts; TestServeProfileReindexPOST covers the happy admin
path; matrix entries cover the gate (anonymous/non-admin → 404, admin
GET → 405 method-not-allowed since the route is POST-only).

Refreshes //go:embed bytes off fe28a73. Dev image now ships the new
tables renderer (handler-local embed at handler/tables.html) plus
build-label refresh on the six cascade-served tools.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Resolved `.archive/<tracking>.html` URLs now serve the target file's
bytes inline via http.ServeFile with Cache-Control: no-cache, replacing
the previous 302 redirect to the per-transmittal URL.
Why: external links like `.archive/<tracking>.html#section` are meant
to track the latest revision. A redirect exposes the snapshot URL — any
forwarded link then pins to that snapshot instead of "latest." Serving
in-place keeps the `.archive/` URL stable as the resolver's "current"
target moves over time.
Cache-Control: no-cache is intentional. Each load revalidates against
the on-disk file's Last-Modified/ETag, so when a new revision lands the
resolver picks it and the browser refetches transparently.
ACL is unchanged: enforced on both the `.archive` context directory and
the resolved target file (per-target denial returns 404, not 403, to
avoid disclosing that a tracking number exists in a hidden subtree).
archivehandler_test.go status expectations updated 302 → 200; fixture
bodies adjusted for body-content verification of the in-place serve.

Tables is the eighth HTML tool: a read-only tabular view over a
directory of YAML files declared via `tables:` in `.zddc`. Anchor use
case is the Master Deliverables List, where each row is one
`<tracking>.yaml` under `Archive/<Party>/MDL/`. Rows click through to
the existing form renderer for editing.
Schema (zddc/internal/zddc/file.go)
- New `Tables map[string]string` on ZddcFile. Map key becomes the URL
stem (`tables[MDL]` → `<dir>/MDL.table.html`); the value is a path
relative to the .zddc pointing at a `*.table.yaml` spec describing
columns + the rows directory. No upward cascade in v1 — each
directory hosting a table declares it directly.
Server handler (zddc/internal/handler/tablehandler.go)
- `RecognizeTableRequest` matches GET `/<dir>/<name>.table.html`
against the cascade's `tables:` declarations. Dispatch routes
table requests before the form-system intercept.
- `ServeTable` ACL-gates with `policy.ActionRead` and serves the
embedded `tables.html` template; client walks the directory itself
via the listing JSON or FS Access API.
- tables.html embedded via //go:embed — same pattern as form.html.
Frontend (tables/)
- Vanilla JS: app/context/util/filters/sort/render/main modules.
- Reads spec + row YAML files via window.zddc.source (HTTP polyfill
or local FS handle); js-yaml 4.1.0 vendored in shared/vendor for
client-side parsing.
- Sample fixtures under tables/sample/ for local testing.
Build + CI
- Lockstep build registers tables alongside the other 7 tools (HTML
output, embed mirror, versions.txt, release-output, tags).
- Playwright project added; `npx playwright test --project=tables`
is part of `npm test`.
Drive-by: rename mdedit Playwright selectors `#select-directory` →
`#addDirectoryBtn` to fix three pre-existing failing tests.
Drive-by: ignore locally-built `zddc/zddc-server` binary so it doesn't
get accidentally staged.

Refreshes the //go:embed bytes off 3115e38. Dev image (ZDDC_REF=main)
now ships the file API and verb-based RBAC.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.

Adds a second way to configure the apps signing pubkey alongside the
existing --apps-pubkey / ZDDC_APPS_PUBKEY (path-to-PEM-file) form: an
inline PEM block under apps_pubkey: in the root .zddc file. Resolution
order:
1. --apps-pubkey / ZDDC_APPS_PUBKEY (path) ← env/flag wins
2. apps_pubkey: inline PEM in root .zddc ← second
3. nothing ← URL fetches refused
Honored only at the root .zddc — same trust-anchor treatment as the
existing admins: field. Subtree write authority cannot re-anchor
trust because subtree apps_pubkey: entries are ignored. (Same
unmarshal pattern as the rest of ZddcFile; the root-only enforcement
is in setupApps where we explicitly read filepath.Join(cfg.Root,
".zddc") rather than walking a chain.)
Why offer both: env/flag fits k8s + systemd deployment shapes where
the operator already manages a config volume and prefers env-based
plumbing. Inline-in-.zddc fits the "everything in one config file"
mental model and matches how operators already think about admins:
and acl:. Either ships a working URL-fetch-verify story; the choice
is operator preference.
Logged differently per source so operators can grep for which path
populated the key:
apps signing pubkey loaded source=env/flag path=/path/to/pubkey.pem
apps signing pubkey loaded source="root .zddc apps_pubkey"
Smoke-tested end-to-end: a root .zddc with inline apps_pubkey: PEM
block + apps: archive: <upstream-URL> + ZDDC_APPS_PUBKEY unset —
the server logs "loaded source=root .zddc apps_pubkey" at startup,
fetches the URL, verifies the .sig against the inline key, caches.
Tampering still rejects; missing .sig still rejects; everything that
worked yesterday still works.
Docs: env-var tables in zddc/README.md and AGENTS.md note the
inline alternative; the federal-readiness gap analysis subsection
on code signing now lists both paths in its resolution order; the
release-page "Verify your downloads" section mentions both for
operators.
Production binary unchanged at ~13 MB. All 11 Go test packages green.

Two interlocking pieces shipped together:
1. Strict Ed25519 signature verification on URL-fetched apps artifacts.
Every URL the apps cascade resolves must publish a corresponding
<url>.sig (raw 64-byte Ed25519 signature). The fetcher rejects on
any failure (sig 404, transport error, wrong key, tampered body)
and the resolver falls back to the embedded copy.
The trusted public key is OPERATOR-CONFIGURED via --apps-pubkey /
ZDDC_APPS_PUBKEY (PEM file path). No baked-in default — same posture
as TLS certificates. Operators using zddc.varasys.io's canonical
channels download pubkey.pem from there and configure the local
path. Operators with their own signing infrastructure pass their
own public key.
Build pipeline (./build) gains sign_release_artifacts: walks
dist/release-output/ after promote and produces an Ed25519 .sig
alongside every real file. ZDDC_SIGNING_KEY=~/.config/zddc-signing/
key.pem (mode 0600). Symlinks skip — the .sig at the symlink
target is what counts.
Test coverage: parse-PEM round-trip, malformed/wrong-type PEM
rejection, valid-signature accept, tampered-body reject, wrong-key
reject, malformed-signature reject, end-to-end fetch+sign+verify,
fetch-rejects-tampered, fetch-rejects-missing-sig, fetch-rejects-
wrong-key. Existing fetch tests updated to use signed-fixture
helpers.
2. Dev Helm chart mounts production data READ-ONLY and layers an
OverlayFS writable scratch on top. Prod data is the lowerdir;
dev's writes (form submissions, archive index state, .zddc edits)
land in upperdir; main container sees the merged read-write view
at $ZDDC_ROOT. Setup runs in a privileged init container; main
container runs unprivileged. Solves the dev-replica-on-shared-
dataset problem at the filesystem layer with no zddc-server code
change.
Docs: env-var tables in zddc/README.md and AGENTS.md gain a
ZDDC_APPS_PUBKEY row. The Federal-readiness gap analysis "Code-signed
apps: URL fetches" subsection is rewritten as "what's currently in
place" instead of "what would need to be added," with a forward
pointer to per-entry signed_by: (multi-key) and Sigstore as the
federally-acceptable evolution.
The website "Verify your downloads" section + the embedded pubkey
gone — but the website needs separate updates landing in zddc-website
to publish pubkey.pem and add the verify section. Pending in that
repo's commit.
Production binary unchanged at 13.1 MB. All 11 Go test packages green.

Two doc/website improvements:
build:341 build_releases_index() — new "Build your apps: block" section
between the pinning narrative and the channels explainer. Per-app
dropdowns (one each for archive/transmittal/classifier/mdedit/landing),
a live-updating YAML textarea, and a Copy button. The dropdowns clone
their options from the existing #version-picker (channels at top,
pinned versions below) so we don't duplicate version data into JS —
the picker is the single source of truth for "what versions exist."
~80 lines of HTML+JS added; no SHA-256 anywhere (per user direction
that code signing is the future supply-chain answer, not hash pinning).
zddc/README.md § Federal-readiness gap analysis — promoted four items
that previously were one-line bullets to per-item subsections so a
future implementor doesn't have to redo the design conversation:
- FIPS-validated cryptography (NIST SC-13): captures cgo + OpenSSL
implications, the platform-matrix reality, and the parallel
zddc-server-fips build target architecture (linux-amd64 only,
RHEL/UBI base, validated OpenSSL on host).
- Authenticated proxy↔server channel (NIST IA-3): mTLS vs JWT
trade-offs spelled out. Recommended: JWT first; mTLS available
for deployments that already operate a private CA.
- Policy export for change control (NIST CM-3): zddc-server policy
export subcommand emitting every directory's resolved ACL in
JSON / Markdown / CSV. Reuses zddc.ScanZddcFiles +
zddc.EffectivePolicy + zddc.MatchesPattern.
- Code-signed apps: URL fetches (NIST SI-7): replaces SHA-256
pinning (operator hash-tracking burden) with code signing
(operator trusts a public key once). Three-part implementation
(build pipeline signs, public key on website, verifier in
apps/fetch.go).
The bullet list at the top of the gap analysis stays as a one-line
index pointing at the subsections.
Items #6 (ABAC roles) and #7 (logs: block in root .zddc) stay as
bullets — commercial-deployment features, not federal-track.
No code changes to the binary. No tests touched. ~280 lines added
across the two files.

Ship a second parity-tested Rego policy that flips the cascade's
leaf-allow-overrides-parent-deny rule for NIST AC-6 conformance.
Standard cascade (existing access.rego, mirrors internal Go evaluator):
Bottom-up walk; first explicit match wins; deny-first within a level.
A leaf-level allow CAN override an ancestor's deny. This is the
cascade's intentional delegation property — a project-owner who
re-allows a previously-denied collaborator works as expected.
Federal mode (new access_federal.rego):
Any deny anywhere along the chain is absolute. An allow only matters
if no level (any depth) has denied the same email. Required by
NIST AC-6 default expectations: a central admin's deny at the root
must be unbypassable by a tenant who controls a subtree's .zddc.
Operators run real OPA with this Rego and point ZDDC_OPA_URL at it;
the internal Go evaluator stays on the commercial cascade. The
toggle is "which policy does your OPA evaluate," not a knob inside
zddc-server.
Surfaced via --print-rego flag:
zddc-server --print-rego # standard (default)
zddc-server --print-rego=standard # same
zddc-server --print-rego=federal # AC-6 strict variant
Parity test (federal_parity_test.go) compiles both Regos and asserts:
* They AGREE on every cascade scenario where no ancestor-deny
intersects a leaf-allow (most cases).
* They DISAGREE — by design — on the three scenarios where the
AC-6 rule differs:
- "leaf allows what parent denied" → standard allows, federal denies
- "deep leaf re-allows after middle deny" → same
- "glob deny at root + specific allow at leaf" → same
Cross-checks the divergence flag explicitly so any future change that
accidentally collapses the two policies fails the test.
Closes the AC-6 row of the federal-readiness gap analysis (now marked
"partially complete" in zddc/README.md — the full bullet would be a
built-in --policy-mode=federal toggle that also flips the in-process
Go evaluator).
Production binary unchanged at 13.1 MB (Rego files embedded as bytes;
OPA library remains test-only).

Eliminates the manual cascade-trace ritual when debugging "why can't
alice see /Project-X" reports. New endpoint returns the resolved
policy chain plus the active decider's verdict in JSON:
GET /.profile/effective-policy?path=/Project-X/sub/&email=alice@…
Response shape:
{
"path": "/Project-X/sub/",
"email": "alice@…",
"decision": true,
"decider_kind": "*policy.InternalDecider",
"chain": {
"has_any_file": true,
"levels": [
{"index": 0, "zddc_path": "/.zddc", "exists": true,
"acl": {...}, "admins": [...],
"matches_email": false, "decision_at_level": "no_match"},
{"index": 1, "zddc_path": "/Project-X/.zddc", "exists": true,
"acl": {...}, "matches_email": true, "decision_at_level": "allow"}
]
}
}
Per-level email matching reuses the same MatchesPattern code the live
evaluator uses, so the trace can never disagree with the actual
verdict — and when ZDDC_OPA_URL points at an external OPA, the
decision goes through that OPA, making the endpoint a useful smoke
test for OPA wiring too.
Admin-only via the existing /.profile gate (404 to non-admins).
Required params; 400 if either is missing or path doesn't escape ROOT.
Test coverage:
* TestServeProfileGateMatrix: anonymous → 404, non-admin → 404,
admin without params → 400 (gate cleared, validator rejected)
* TestServeProfileEffectivePolicy: full payload-shape assertion
against a worked-example fixture (closed project where alice is
allow-listed but bob is not)
Also fixes pre-existing doc drift: README's "Admin Debug Page"
section referenced /.admin/whoami|config|logs but the actual code
mounts /.profile/* (the rename predates this PR; the doc was stale).
Closes the "/.admin/effective-policy debug endpoint" item from the
federal-readiness future-work list.

The previous keyForURL stripped default ports (:443 for https, :80
for http) and omitted the scheme, so:
http://example.com/x.html ──┐
https://example.com/x.html ──┴──→ same cache entry (collision)
https://example.com/x.html ──┐
https://example.com:443/x.html ──┴──→ same cache entry
This was a defensible HTTP convention but a real correctness issue
on reverse-proxy stacks where http and https legitimately serve
different bytes for the same path, or where two upstreams share a
host but answer on different default ports.
New layout: <scheme>/<host>[:<port>]/<path>. Full origin tuple in
the key, no port stripping, scheme segregation. Examples:
https/zddc.varasys.io/releases/archive_stable.html
https/example.com:8443/x.html
http/example.com/y.html (distinct from https/example.com/y.html)
Operators retain the "ls _app/ to inspect what's cached" affordance
they relied on; they just see one extra directory layer (scheme
first, then host).
Tests:
* Updated TestKeyForURL to assert the new layout for every
previously-covered case
* New TestKeyForURL_NoCollisions explicitly asserts that the
dimensions previously collapsed (default-port↔bare, http↔https,
different non-default ports) now produce distinct keys
Doc references to the cache layout under <ZDDC_ROOT>/_app/ updated
in zddc/README.md (3 mentions).
NOTE: existing _app/ caches under the old layout will be ignored
on first request after upgrade — entries will be re-fetched and
written to the new path. Operators can `rm -rf <ZDDC_ROOT>/_app`
during the upgrade window if they prefer not to have orphans.

The TLS configuration was using Go stdlib defaults — secure for typical
commercial use, but federal evaluators need an explicit cipher
allowlist they can map to a FIPS-validated implementation. Pin the
cipher and curve lists to NIST SP 800-52 Rev. 2 § 3.3 conformant
values:
Ciphers (TLS 1.2):
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305
TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305
Curves: X25519, P-256, P-384
MinVersion: TLS 1.2 (already set; 1.3 used when negotiated)
TLS 1.3 cipher selection is not operator-controllable in Go stdlib
(the runtime picks from a fixed AEAD-only set); all of those
already meet the federal bar so no change needed there.
Also adds HSTSMiddleware emitting `Strict-Transport-Security:
max-age=31536000; includeSubDomains` when zddc-server is itself
terminating TLS (ZDDC_TLS_CERT != none). Behind an upstream proxy
terminating TLS the proxy is responsible for HSTS, so the middleware
only wraps the chain when useTLS=true.
Test coverage:
* TLSConfig(none) returns nil + useTLS=false
* TLSConfig(selfsigned) sets the exact NIST allowlist
* Negative test asserting weak ciphers (CBC, RC4, 3DES, RSA-key-
exchange) are NOT in the list — guardrail against regressions
Federal-readiness gap analysis updated: this control is now partially
complete. OCSP stapling and CT-log inclusion remain on the list for
full DoD STIG conformance.

Three docs aligned with the preceding three feature commits.
zddc/README.md
--------------
Major overhaul of the access-control narrative. The previous "three-
tier" example table was misleading: it claimed a project-level
allow-list "restricts" access under a parent wildcard, when actually
the cascade is additive (a non-team employee falls up to root and
matches *@company.com). Operators reading the old docs would build
deployments that looked locked-down but leaked across the company.
New sections under "Access control: the .zddc cascade":
* Step 1: starter .zddc — leads with the public-by-default warning
and the --insecure escape hatch
* How a request is evaluated — bottom-up walk with code citations
* Glob patterns — @-boundary rule
* When the cascade helps and when it fights you — the asymmetry
between adding strangers (easy) and excluding insiders (hard)
* Pick your layout — decision matrix for common shapes
* Worked example: paired open/closed projects + third-party archive
— full layout with trace table for two representative users
* Patterns that look secure but aren't — anti-patterns including
same-level allow+deny shadow, leaf-allow-doesn't-restrict,
apps:-as-UI-mount
* Trust model and invariants — auth boundary, subtree authority,
root-only escalation gate
* Trust boundary — network isolation requirement, anonymous
information disclosure on /, audit-log integrity
* Debugging permissions — manual cascade trace
* Directory visibility / Reserved hidden segments
* How to verify in 5 minutes — recipe with negative anti-pattern test
* Federal-readiness gap analysis — bulleted with NIST control refs
* External policy decider — OPA wire format, deployment shapes,
failure modes
* OPA decision cache — TTL semantics, knobs
* Reference Rego policy — --print-rego, parity test rationale
* Caching and ETags — content-hash story, why not server-side
* Future work
Plus env-var table updates for ZDDC_INSECURE, ZDDC_OPA_URL,
ZDDC_OPA_FAIL_OPEN, ZDDC_OPA_CACHE_TTL; CORS narrative reflects
default-empty.
ARCHITECTURE.md
---------------
New "Server security model" section between Form Renderer and CSS:
cooperating layers (auth / policy decider / cascade / tool-rooted
view / reserved prefixes / audit log), commercial-vs-federal trust
model side-by-side, why the tool-rooted view matters for third-party
containment.
AGENTS.md
---------
Two new env-var rows (ZDDC_OPA_URL, ZDDC_OPA_CACHE_TTL); ACL line
sharpened with cascade rules + cross-reference; ZDDC_CORS_ORIGIN
description updated for default-empty.

Phase 2 enhancements to the policy decider, plus listing-level ETags
that benefit every deployment regardless of decider mode.
Reference Rego policy
---------------------
internal/policy/rego/access.rego mirrors InternalDecider's semantics
exactly — bottom-up walk, deny-first within a level, default-deny when
HasAnyFile=true, glob matching with @-boundary semantics (special-cased
bare "*" because OPA's glob.match treats empty delimiters
inconsistently for that pattern).
Embedded into the binary via go:embed; --print-rego dumps it to stdout
so federal customers standing up an external OPA can use it as a
parity-tested baseline:
zddc-server --print-rego > /etc/opa/policies/zddc-access.rego
Parity test runner
------------------
parity_test.go imports the OPA Go module as a TEST-ONLY dependency
(github.com/open-policy-agent/opa@v0.70.0). Every fixture from the
internal Go evaluator's test set runs through both implementations;
any divergence fails CI. The test-only import means production
binaries (built by `go build ./cmd/zddc-server`) stay OPA-free —
release-flag binary size unchanged at ~13 MB.
The parity test caught a real bug on first run: bare "*" patterns
didn't match through OPA's glob.match with empty delimiters. Fixed
in access.rego with a special-case rule. This is exactly the kind of
subtle drift the parity guard exists to catch.
External-mode decision cache
----------------------------
HTTPDecider is now wrapped in a cachingDecider with a default 1s TTL.
Bursty patterns like .archive listings (one OPA round-trip per entry
before, one per (email, decision-input) tuple per TTL window after)
amortize cleanly. Verified: 20 identical /D/ requests produce 1 OPA
hit with cache, 40 hits without (each listing makes 2 ACL queries).
ZDDC_OPA_CACHE_TTL knob (default 1s) lets operators tune. 0 disables.
1s matches the fsnotify watcher debounce window — staleness is
bounded the same way other policy-edit propagation already is.
Internal mode unchanged; the in-process Go evaluator is already
cheaper than a cache lookup would be.
Listing ETags
-------------
GET / (project list) and GET /<dir>/ (directory listing JSON) now
carry content-hash ETag + Cache-Control: private, max-age=0,
must-revalidate. SHA-256 of the rendered JSON, truncated to 16 hex
chars (64 bits — collision risk on a listing of any realistic size
is vanishingly small).
Server-side caching deliberately not added: it would require
mtime-based invalidation, and Azure Files SMB mounts (a common
deployment substrate) don't support fsnotify reliably. The
content-hash ETag delivers the bandwidth savings (304 on identical
fetches) without depending on watcher correctness — the hash is the
actual response, so it can't lie about staleness regardless of
underlying watcher behavior.

Add an internal access-decision boundary that all handlers go through
instead of calling zddc.AllowedWithChain directly. Two implementations
ship:
* InternalDecider — wraps the existing zddc.AllowedWithChain. The
default. No new dependencies, identical semantics to the legacy
code path. ZDDC_OPA_URL=internal (or unset).
* HTTPDecider — POSTs the canonical OPA wire format
(POST /v1/data/zddc/access/allow with {"input": {...}}, response
{"result": true|false}) over HTTP, HTTPS, or a Unix-domain socket.
For federal customers running their own audited Rego policies
alongside zddc-server. ZDDC_OPA_URL=http(s)://… or unix:///….
External-mode failure semantics: unreachable / non-2xx / malformed
response → fail closed (deny) by default with a WARN log. Operators
who prefer availability over correctness flip with ZDDC_OPA_FAIL_OPEN=1.
The decider is constructed once at startup, plumbed through ACLMiddleware
into the request context. Handlers retrieve it via DeciderFromContext;
non-request callers (fs.ListDirectory, EnumerateProjects, enumerateAccess)
take it as an explicit parameter.
zddc.ZddcFile and zddc.ACLRules gain JSON tags so external Rego authors
get idiomatic input shape (acl.allow, admins, …) instead of Go field
names (ACL.Allow, Admins, …).
Test coverage:
* InternalDecider parity tests against zddc.AllowedWithChain (every
documented cascade scenario: empty chain, leaf-allow-wins, leaf-
deny-beats-parent, leaf-allows-what-parent-denies, deepest-match-
wins, etc.)
* HTTPDecider happy-path test (canonical wire format)
* Fail-closed / fail-open / malformed-response tests
Production binary size unchanged (no new deps; HTTP transport is
stdlib net/http). 11 ACL call sites migrated. End-to-end verified
against the worked-example layout in zddc/README.md.

Two safe-by-default flips, both opt-out via explicit acknowledgement.
1. --insecure / ZDDC_INSECURE=1: zddc-server now refuses to start when
no <ZDDC_ROOT>/.zddc exists. With no .zddc anywhere in the chain,
AllowedWithChain falls through to "HasAnyFile=false → allow" and
the tree is publicly accessible to anonymous callers — almost never
what an operator wants on a fresh deployment, and previously a
silent footgun. The flag is the escape hatch for deliberately-
public archives (no .zddc anywhere by design).
2. ZDDC_CORS_ORIGIN now defaults to empty (CORS disabled) instead of
the canonical "https://zddc.varasys.io". The embedded-tools install
path serves tools and data same-origin, so the default never needed
to permit cross-origin XHRs from a third-party host. Every deployment
was implicitly trusting zddc.varasys.io to make authenticated XHRs
on behalf of every logged-in user; if that origin were ever
compromised, the blast radius extended to every customer server.
Operators who deliberately use the CDN-bootstrap pattern or self-
hosted tools at a different host now set the value explicitly.
Helm chart values updated accordingly: prod default is empty; dev
keeps localhost:8000 for tool-iteration workflows. Existing deployments
that depended on the old defaults will need to either set the value
explicitly or pass --insecure.

The recent history rewrite (squash of 4 thrash CI commits) made the
chart's previous appVersion (0.0.16-beta-8df0def) reference a now-
dangling commit. The dev pipeline failed clone "remote ref not
found" until we re-bumped to a SHA in the new history.
Re-cut beta with the new HEAD parent (ae75855) so notify-chart-dev
rewrites the chart's appVersion to a SHA the BMCD dev pipeline can
actually fetch. Combined with the Dockerfile clone-via-fetch fix in
tnd-zddc-chart 86c5758 (handles bare SHAs), the dev pipeline should
build cleanly.
Two related operational improvements:
1. HTTP timeouts on http.Server (ReadHeaderTimeout 10s, ReadTimeout +
WriteTimeout 60s, IdleTimeout 120s). Caps slow-client connection
hold time; closes the slowloris vector. Listing + tool-HTML
responses complete in milliseconds even with gzip, so 60s is
generous for legit traffic.
2. --access-log defaults to <ZDDC_ROOT>/.zddc.d/logs/access-<host>.log
instead of stderr-only. The server auto-creates the parent tree
(mode 0750), so a fresh deployment gets an audit trail without
operator setup. Every JSON record carries a `host` field (from
os.Hostname) — multi-replica deployments share the .zddc.d/logs/
directory but write to per-host filenames, and downstream
aggregators can disambiguate via the host field.
Opt-out: --access-log= (explicit empty). Distinguishing "unset"
from "set to empty" follows the same pattern config.go already
uses for --cors-origin.
