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

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.

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.

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

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.
