Replace the blanket "block every dot/underscore segment" dispatch guard
with a single reserved namespace, .zddc.d/, which is admin-only at every
depth. Everything else dot-prefixed is now ordinary ACL-governed content;
a leading dot only hides an entry from listings (UI), not from the ACL.
.zddc.d/ holds the bearer-token store, so it must stay closed even under a
broad operator grant (e.g. `*: rwcd`). The path-tree cascade has no
match-this-name-at-any-depth rule, so .zddc.d/ is gated by segment name via
a hard rule that overrides operator ACLs — on reads in dispatch (404,
existence-hidden) and on writes in authorizeAction (403 defense-in-depth
for direct callers). Token validation is unaffected: it reads
.zddc.d/tokens directly from the filesystem in ACLMiddleware, before the
HTTP-layer gate.
The segment match is case-insensitive (strings.EqualFold): ZDDC_ROOT may
sit on a case-insensitive filesystem (SMB/CIFS/Azure Files) where .ZDDC.D
resolves to the same dir, so a write to a case-varied path — e.g. a MOVE
destination header that skips dispatch's canonical case-folding — must not
slip past the gate and plant a forged token. The dispatch gate also runs
BEFORE the raw .zddc view so the reserve's own cascade
(/<dir>/.zddc.d/.zddc) is existence-hidden rather than leaked by
ServeZddcFile. Regression tests cover both.
To keep all bookkeeping inside the one reserve, relocate the last two
caches under it (both regenerable, no data migration): the apps cache
_app/ -> .zddc.d/apps/ and the per-directory MD-conversion cache
<dir>/.converted/ -> <dir>/.zddc.d/converted/.
New internal/handler/sidecar.go defines ReservedSidecar + the
HasReservedSidecar / ActiveAdminForSidecar predicates used by both the
dispatch read-gate and the write-path gate.

Releases publish only two things per tool now: a current-stable
canonical symlink and an immutable per-version file. No more channel
mirrors (_stable/_beta/_alpha) and no more partial-version pins
(_v<X.Y>, _v<X>) — those were debt from a release model that never
matched the project's actual usage.
The `./build beta` verb stays, but narrowed: it's an internal SHA
snapshot for the BMC dev chart pipeline (chart's appVersion pins to
"<X.Y.Z>-beta-<sha>" and the chart Dockerfile fetches that SHA from
git). No public artifact on /srv/zddc/releases/. The embedded/* +
chore commit produced by `./build beta` is the actual snapshot.
`./build alpha` is removed entirely.
build/build-lib.sh:
- Drop alpha verb; narrow beta verb to embedded regen + chore commit
- promote_release: stable cut writes <tool>_v<X.Y.Z>.html + <tool>.html
symlink + <tool>.html.sig companion symlink; beta is a no-op
- promote_zddc_server: same shape — per-version binary +
per-platform canonical symlink (zddc-server_<plat>) + .sig symlink
- write_zddc_server_stub: singular; emits per-version stubs +
one canonical zddc-server.html for current stable
- Delete _promote_channel, verify_channel_links, _channel_is_active
- Seed-from-live now copies only per-version files + .sig + pubkey.pem
(the canonical symlinks get rewritten by this cut; old layout files
get cleaned by deploy's --delete-after)
- build_releases_index: dropdown simplified to "latest stable +
pinned versions"; channels-explainer section removed; tool cards +
CTA URLs point at canonical <tool>.html / zddc-server_<plat>;
composer emits "stable" sentinel for `apps:` entries
- Fix the acl:{allow:[...]} footgun in the apps_pubkey example
apps.go:
- isValidChannelOrVersion: accept only "stable" + exact X.Y.Z
(drop alpha/beta and partial pins v0.0/v0)
- normalizeChannel: same
- Resolve URL composition: stable → canonical <prefix>/<app>.html
(no _stable_ suffix), exact-version → <prefix>/<app>_v<X.Y.Z>.html
- Tests rewritten to match (beta/alpha replaced with v0.0.4 / stable;
a new TestParseSpec_RejectsLegacyChannelsAndPartialPins locks in
that the removed forms now error)
browse/build.sh: gate promote_release on $is_release like every other
tool's build.sh (longstanding inconsistency that errored under the new
promote_release case-statement).
freshen-channel: deleted (no channels to freshen).
Net: -254 lines, all green on full `go test ./...`. Dev build verified
via `./build` (no-arg) — new label format "v<next>-dev · <ts> · <sha>".

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.
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.
