Foundation for the generalized view model: `.zddc` declares, per URL shape,
which tool renders and where its supporting config lives.
- ZddcFile.Views map[string]ViewSpec{Tool, Config}; shapes "dir" / "dir_slash"
/ "file". config is a filename resolved under <dir>/.zddc.d/. Pure data — no
behaviour; presentation/routing only (ACL/WORM/admin stay server-enforced).
- lookups.ViewAt(root, dir, shape): cascade leaf→root first-match, with
default_tool / dir_tool honored as sugar for dir / dir_slash (semantics
unchanged). No merged map — resolved per-shape like DefaultToolAt.
- cascade summary, isZero/is-empty checks, and validation (tool ∈ AppNames;
config a path-bounded plain filename). Client .zddc validator (preview-yaml.js)
gains a `views` key + `viewmap` case.
Additive only — nothing consumes Views yet (the generic resolver + dispatch
wiring + recognizer retirement follow). go build + zddc/handler tests green.

Replaces the URL/channel/version-fetching tool-HTML system with a
local-only override model. No network fetch, no Ed25519 signatures, no
channels/versions, no `apps:` .zddc key.
Tool HTML resolves, in precedence:
1. a real file on disk at the path (operator drops browse.html / archive.html
/ a new mytool.html) — served by the existing static handler;
2. an `<app>.html` member of the site-root <ZDDC_ROOT>/.zddc.zip bundle, read
server-side via internal/zipfs (local file, no fetch, no signature;
re-stat'd each request for free hot-reload);
3. the embedded //go:embed default.
Remove (complete unwire):
- internal/apps/{fetch,verify,cache,singleflight}.go and their tests; the
spec-parsing/cascade machinery in apps.go (ParseSpec/Resolve/PreviewLine/
SpecComponents/appsState, DefaultUpstream*/DefaultChannel/CacheDirName).
- --apps-pubkey / ZDDC_APPS_PUBKEY flag+env+Config field; the setupApps
cache/fetcher/pubkey wiring (now just apps.NewServer(root, version)).
- the `apps:` / `apps_pubkey:` .zddc keys: ZddcFile.Apps/AppsPubKey, the
walker merges, cascade-summary adds, validate.go apps validation
(ValidateAppSourceSpec/validateURLSpec/validateChannelOrVersion/
AppsDefaultKey/IsValidAppsKey), and the isZero/is-empty refs. A stale
apps:/apps_pubkey: in an existing .zddc is now silently ignored
(back-compat), not a parse error. Client .zddc validator (preview-yaml.js)
drops the apps/apps_pubkey keys + appsmap case.
Add:
- internal/apps/bundle.go — nil-safe Bundle over <root>/.zddc.zip with
stat-based hot-reload, size caps, corrupt-zip tolerance.
- handler.go: Server{Bundle}, resolveBytes (bundle→embedded), simplified
Serve; X-ZDDC-Source = bundle:<m> / embedded:<app>@<ver>.
- dispatch: GET /.zddc.zip is 404 for everyone (config, not content); the
server reads members from the filesystem internally.
Tests: new bundle_test.go (member hit/absent/no-file/hot-reload/corrupt);
handler_test.go rewritten for bundle-overrides-embedded, absent-member→
embedded, unknown-tool 503, conditional-GET for both sources; dispatch test
covers bundle override + /.zddc.zip 404 + availability rules. go build/vet/
test ./... all green; gofmt clean. Docs (AGENTS.md, ARCHITECTURE.md) updated.

Single audit pass that removes pre-release back-compat, consolidates the
admin-policy decider, and fixes the .zddc write path.
Field removal — acl.allow / acl.deny:
- Drop ACLRules.Allow / Deny struct fields and mergeLegacyACL().
- Remove walker / lookups / validate / decider branches that read them.
- Migrate every test fixture (YAML strings and ACLRules struct literals)
to acl.permissions: { principal → verb-set }.
- Rewrite both bundled Rego policies (access.rego, access_federal.rego)
to traverse level.acl.permissions; rewrite parity-test helpers.
- Update create-project form (profile page) to collect permissions
instead of allow/deny lists.
Admin decider consolidation:
- Delete zddc.CanEditZddc — strict-ancestor rule retired. Subtree admins
own their own .zddc; the policy decider's IsActiveAdmin short-circuit
is the single bypass site.
- Migrate tablehandler.ServeTable to AllowActionFromChainP — closes the
same Forbidden bug already fixed for /browse.html.
- Drop AccessView.EditableParentChoices and treeEntry.CanEdit (always
true after the retirement). Profile page renders AdminSubtrees
directly for both lists.
- Drop the excludeLeaf parameter from AdminLevelInChain /
IsAdminForChain — no production caller passed true.
Dead code removed:
- policy.AllowWriteFromChain (zero production callers, zero tests).
- zddc.AllowedWithChain (zero production callers; tests deleted).
ModeStrict retirement — federal posture is OPA-only:
- Delete cascade_mode.go / cascade_mode_test.go and the ModeStrict
branches in cascade.go and acl.go.
- Drop --cascade-mode flag, CascadeMode config field, and the
InternalDecider.Mode field.
- Drop the mode parameter from every cascade helper:
GrantedVerbsAtLevel, AllowedAction, EffectiveVerbs,
EffectiveVerbsRange, RoleMembers, MatchesPrincipal,
MatchingPrincipals, WormZoneGrant, PolicyChain.VisibleStart.
- Strip cascade_mode from /.profile/config and
/.profile/effective-policy responses.
- Refresh README / ARCHITECTURE.md to describe federal posture as
"deploy OPA with access_federal.rego" (NIST AC-6); the bundled Rego
is the parent-deny-is-absolute variant. The in-process Go evaluator
implements only the commercial cascade.
Legacy redirects + .admin.css fallback:
- Drop /<dir>/.zddc.html → ?file=.zddc redirect and its test.
- Drop ?zip=1 retired comment + legacy test (handled by the
.zip virtual-URL path; covered by TestServeSubtreeZip).
- Drop .admin.css fallback in profile_assets.go — only .profile.css now.
- Refresh stale "retired" / "back-compat" / "legacy" comment markers.
.zddc write path fix:
- Dispatcher: route only GET/HEAD on .zddc URLs to ServeZddcFile; carve
.zddc out of the dot-prefix guard so PUT/DELETE/POST reach
ServeFileAPI. Before this, .zddc writes 405'd at ServeZddcFile and
the YAML editor's save flow had no live path.
- ServeFileAPI.resolveTargetPath: same .zddc-leaf carve-out so the file
API accepts the path; intermediate dot dirs (.zddc.d/) stay reserved.
- Listing: compute Writable per-file with ActionAdmin for .zddc
(matches the file API's gate) instead of ActionWrite for everything.
- Virtual .zddc placeholder: compute Writable via the same
parentActiveAdmin || ActionAdmin path. Was always false before.
- browse YAML editor canSave: exempt virtual .zddc — the synthetic
body is designed to materialize on PUT.

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.
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.

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.

Adds internal/apps/ package serving the five tool HTMLs at virtual paths
based on the surrounding folder name convention:
archive every directory (multi-project, project, archive, vendor)
classifier any Incoming/Working/Staging directory and subtree
mdedit any Working directory and subtree
transmittal any Staging directory and subtree
landing only at deployment root
The current-stable build of every tool is //go:embed'd into the binary
at compile time — that's the default with zero config. Operators
override per-directory via .zddc apps: entries; closer-to-leaf wins.
Spec syntax (in any apps: value):
stable / beta / alpha / :stable channel
v0.0.4 / v0.0 / v0 / :v0.0.4 version
https://my-mirror/releases URL prefix only
https://my-mirror/releases:beta URL prefix + channel
https://my-fork/archive.html terminal full URL
./local.html / /abs/path.html terminal local path
The special apps.default key provides a baseline URL prefix and channel
inherited by any app not overridden per-name. Per-axis cascade: a deeper
.zddc can override the URL, the channel, or both.
Cascade walks root→leaf; default applies first at each level, then the
per-app entry. Terminal sources (paths and full .html URLs) short-circuit
composition; deeper non-terminal entries override parent terminals.
URL sources fetch once on first request and cache forever in
<ZDDC_ROOT>/_app/<host>/<path> — different upstreams with the same
filename stay distinct. No background refresh, no SHA-256 verification:
operators delete the cache file to force a refetch. Concurrent misses
for the same source dedupe via a 30-line hand-rolled singleflight.
Per-request override: any user can append ?v=<spec> to a tool URL
(e.g. ?v=beta, ?v=v0.0.4, ?v=:alpha, ?v=https://mirror/releases:beta)
to ask for a different build for one request. Security: ?v= serves
ONLY versions already in the cache (cache miss returns 404; path
sources are rejected outright with 400). Users cannot trigger
arbitrary upstream fetches via crafted URLs.
Failed URL fetches (network down, 5xx) fall back to embedded with a
one-time WARN log. The X-ZDDC-Source response header reports what
served: fetch:URL / cache:URL / path:/abs / embedded:<app>@<build>.
Wire-in (cmd/zddc-server/main.go): dispatch routes <dir>/<app>.html
through apps.MatchAppHTML + AppAvailableAt + apps.Server.Serve when
no real file exists. Direct URL access to /_app/... is blocked at
the dispatch layer — cached files must go through the apps resolver
so they get correct Content-Type and ACL gating.
Schema (internal/zddc/file.go): ZddcFile gains Apps map[string]string
for cascade overrides. Validator (internal/zddc/validate.go) accepts
the special "default" key alongside the five canonical app names and
all spec forms.
Removes ZDDC_APPS_* env vars (no admin UI, no refresh interval, no
upstream allow-list — the simpler model has fewer knobs).
40+ unit tests across the new package: parser shapes, cascade
resolution with default+per-app interactions, terminal short-circuit
semantics, ?v= cache-only enforcement, embedded fallback, atomic
cache writes, singleflight dedup. Plus end-to-end dispatch tests in
cmd/zddc-server/main_test.go.

Replaces the super-admin-only /.admin/ surface with a public-by-default
/.profile/ page that layers admin tools server-side based on the
caller's effective access:
- Universal (everyone, anonymous included): identity card, effective
access summary, theme picker, localStorage utilities (export / import
/ clear, landing-presets viewer).
- Subtree admins additionally see: editable .zddc files list (linking
to the existing form-based editor) and a "Create new project folder"
form.
- Super-admins additionally see: server config, log viewer, whoami
headers (the old /.admin/ JSON endpoints, repointed under /.profile/).
Project creation is gated on CanEditZddc(newDir) — the same strict-
ancestor rule that already governs .zddc writes — so no new authority
concept is introduced. ValidateProjectName mirrors the existing
reserved-prefix policy (no leading '.' or '_', no path separators).
/.admin/* is hard-cut: no redirect shim. Old URLs fall through to the
existing dot-prefix guard and 404. Custom CSS file rename: prefer
<root>/.profile.css, fall back to legacy <root>/.admin.css.
Per-resource 404 leakage gates preserved on whoami / config / logs /
zddc / projects so non-admin callers cannot detect the existence of
admin-only sub-resources.
Tree-wide gofmt -w applied as a side-effect.

Generalize the admin model from "single root super-admin" to a
delegated chain: a `<dir>/.zddc/admins` list grants admin authority
for that subtree, with a strict-ancestor rule preventing
self-elevation (you cannot edit the .zddc that grants your own
authority — only files strictly below it).
Add a guided server-rendered editor at /.admin/zddc/edit?path=<dir>
so subtree admins can manage their fiefdoms without filesystem
access. JSON API at /.admin/zddc covers GET (file + effective chain
+ can_edit), POST (atomic write + cache invalidation), DELETE,
plus a /tree endpoint listing every .zddc visible to the caller.
Optional theming via <root>/.admin.css.
Validation: glob syntax check, root-self-demotion rejection,
reserved-prefix path guard, YAML round-trip sanity. Writes are
atomic (temp file + fsync + rename) and invalidate the policy
cache.
Also includes the prior in-flight `Title` field on ProjectInfo
so per-project .zddc titles surface on the landing-page picker.
