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.

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.

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.

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)

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.

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.

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.

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.

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.

Schema-driven form renderer plus zddc-server endpoints that turn any
<name>.form.yaml into a working data-collection form at <path>/<name>.form.html.
Submissions land in <path>/<name>/<YYYY-MM-DD>-<email-sanitized>.yaml,
ACL-gated by the existing .zddc cascade. The form posts back to its own URL;
the server strips ".html" and routes by what's underneath, so create and
update use the same client-side code path.
Form spec dialect: JSON Schema 2020-12 + RJSF-style ui:* hints, written in
YAML. Chosen for LLM authorability — it's the canonical structured-output
target for OpenAI/Anthropic, and the ui:* convention is the most-trained UI
hint vocabulary. Supported subset for v0: type (string/number/integer/boolean/
array/object), enum, min/max, minLength/maxLength, required, additionalProperties:
false, properties, items, format (date, email). Round-trip mode is form-as-truth:
submission YAML is regenerated each save, comments are not preserved (the v1
file-as-truth mode for hand-edited files like .zddc itself is deferred).
New components:
* form/ — sixth single-file HTML tool, vanilla JS renderer (~760 LoC)
* zddc/internal/jsonschema/ — focused JSON Schema validator covering only
the v0 keyword subset. Match-implementation-cost-to-surface-used: a full
library brings 70%+ surface we don't use; revisit when v1 adds $ref +
oneOf + if/then/else.
* zddc/internal/handler/formhandler.go — RecognizeFormRequest / ServeForm,
capability-URL re-edit, atomic submission writes via the new
zddc.WriteAtomic helper extracted from writer.go.
* dispatch() in zddc-server/main.go now intercepts *.form.html and
*.yaml.html before the static-file path; spec existence is the trigger.
Build pipeline: form joins ZDDC_RELEASE_TOOLS in lockstep, gets its own
embedded copy in handler/form.html (separate from the apps cascade —
the form renderer is fixed, not subject to per-folder version overrides).
Tests: 5 new Playwright specs (form-safety) + 14 new Go tests across the
validator and handler. All 172 Playwright tests + 10 Go packages green.
End-to-end manual verification: GET empty → POST 201 + capability URL →
GET re-edit (pre-filled) → POST update → 200, raw YAML browsable, ACL
deny → 403.
Docs: form/ section added to AGENTS.md and ARCHITECTURE.md. AGENTS.md
also documents the implementation-vs-dependency policy. CLAUDE.md repo-shape
list extended.
Deferred (v1+): .zddc editor migration onto this system, file-as-truth
lossless YAML round-trip, ui:show-when conditional visibility, oneOf/anyOf,
apps-cascade preview hook, cascade-fetched form definitions.

Four entangled change-sets from one session, committed together because
their file-level overlap (build.sh, docs, embedded/, watcher.go, …) makes
post-hoc separation noisy:
* fix(archive): nested-party + folder-type cascade
transmittalIsUnderVisibleParty short-circuited on the first matched
party segment, only checking the immediately-next segment for a
folder-type marker. Paths like BM/sub/Issued/<txn> bypassed the Issued
toggle entirely. Replaced with isUnderHiddenFolderType (full-path) +
any-segment party match. Eight new Playwright cases pin the contract
in tests/archive-cascade.spec.js.
* refactor(zddc-server): scope .archive index by project
archive.Index now buckets by top-level segment
(.ByProject[<project>].ByTracking[<tracking>]). Resolve and AllEntries
take a project parameter; handler extracts it from contextPath's first
segment. /.archive/ at root returns 404 — stable refs must be
project-rooted. Within-project (tracking, rev) collisions emit a WARN
with both paths. Cross-project tracking-number duplicates no longer
collide.
* perf(zddc-server): lazy-load expensive bits of the profile page
serveProfilePage now ships a minimal shell: Email, EmailHeader,
IsSuperAdmin (root .zddc only). Visible projects + admin subtrees +
editable scaffolds populate client-side via /.profile/access. Subtree-
admin scaffolds live in <template id="tmpl-subtree-admin">; pure
non-admins receive no live admin form. ScanZddcFiles now memoized,
invalidated on .zddc events by the watcher and writer helpers.
* feat: lockstep release + redesigned releases page
sh build.sh --release [version|alpha|beta] is the canonical lockstep
cut: every tool (5 HTML + zddc-server) bumps to the same coordinated
version. zddc-server binaries now committed under website/releases/
with the same cascade chain as HTML tools (no more Codeberg release-
asset publication). zddc/release.sh deprecated (kept as a guard);
shared/publish-codeberg-release.sh removed.
Releases page redesigned as an action-first install guide: hero +
version dropdown that rewires every download link, channel chips for
always-visible alpha/beta access (state-aware labels: "tracks stable"
vs "active dev"), Path A (zddc-server with platform auto-detect from
UA), Path B (5 standalone tool HTMLs), version-pinning empowerment
narrative (drop-a-copy vs .zddc apps: cascade), channels explainer.
Channel-link verifier asserts every <tool>_{stable,beta,alpha}.html
resolves at the end of every build. Bootstrap-friendly: zddc-server
artifact checks skip until the first lockstep cut anchors the chain.
Tests: 167 Playwright + all Go packages green.
Docs: CLAUDE.md, AGENTS.md, ARCHITECTURE.md, zddc/README.md updated.

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.

Three improvements bundled because they all ship as zddc-server v0.0.2:
* /.admin/ debug dashboard with /whoami, /config, /logs sub-routes.
Authorization via a top-level `admins:` glob list in <ZDDC_ROOT>/.zddc
(root-only — subdir entries deliberately ignored to prevent privilege
escalation via subtree write access). Non-admin requests get 404 so the
page is invisible. Recent logs surface via a 500-entry slog ring buffer
teed off the existing TextHandler. Lets operators debug without
kubectl exec.
* Default ZDDC_EMAIL_HEADER changes from `X-Email` to
`X-Auth-Request-Email` — the oauth2-proxy / nginx auth-request
convention that the TND helm chart already sets explicitly.
Operators who set the env var explicitly are unaffected; deployments
relying on the previous default need to set ZDDC_EMAIL_HEADER=X-Email
or update their proxy.
* dispatch() rejects any URL whose segments contain a dot prefix other
than the recognized virtual prefixes (.admin, cfg.IndexPath /
.archive). Matches the existing listing-pipeline filter so hidden
subtrees on the served PVC (e.g. /srv/.devshell — used by the
in-cluster dev-shell for persistent home-dir state) become
unreachable via direct HTTP fetch, not just hidden in listings.
Refreshes the X-Email reference in website/index.html accordingly.

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