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.

mdedit was the only tool whose dist/<tool>.html was force-tracked
(via `git add -f` in the build's stable-cut path). Inconsistent with
every other tool in the repo, where dist/ is fully gitignored. The
build regenerates mdedit/dist/mdedit.html the same way it regenerates
the others, so there's no reason to track it.
Drop the `git add -f` line in build:735 and `git rm --cached` the
file. The on-disk artifact stays put for the dev iteration loop;
only the index entry goes away.
A new HTML tool — browse — that lists the contents of any directory.
Designed for ZDDC archives but no ZDDC-specific filtering; just a
straight folder browser with expand/collapse, sort, and name filter.
Modes (auto-detected at page load):
- Online: when served by zddc-server at a folder URL, queries
the same URL with Accept: application/json to load the listing
and renders it. Auto-served as the default at any directory
under ZDDC_ROOT without an index.html (replacing the previous
minimal-HTML stub from directory.go).
- Local: 'Select Directory' button uses FileSystemAccessAPI to
pick any folder on disk; works in Chromium-based browsers.
Features (Phase 1 — what's in this commit):
- Tree view with lazy-loaded folders (children fetched on first
expand).
- Sort by name / size / extension / date (column header click).
- Filter by name substring (toolbar input).
- File click opens in a new tab — for server-backed pages,
routes through zddc-server's normal handler so .archive
redirects + apps cascade overrides + ACL all apply.
Phase 2 deferred:
- ZIP files inline expansion (treat archive entries as virtual
children).
- File preview popup (reuse shared/preview-lib.js).
- Extension multi-select filter.
Wiring:
- browse/ added to top-level ./build's per-tool list, embed
block, versions.txt, and the lockstep release commit + tag set.
All seven tools (archive, transmittal, classifier, mdedit,
landing, form, browse) advance together on stable cuts.
- shared/build-lib.sh: browse added to ZDDC_RELEASE_TOOLS and
verify_channel_links's per-tool loop.
- zddc/internal/apps/embed.go: //go:embed browse.html +
EmbeddedBytes("browse") case.
- zddc/internal/apps/availability.go: browse available at every
directory (same as archive).
- zddc/internal/apps/handler.go: MatchAppHTML routes
/<dir>/browse.html → 'browse'.
- zddc/internal/handler/directory.go: when a directory request
arrives with Accept: text/html and no index.html exists,
serve the embedded browse.html bytes (with a JSON-fallback
if the embedded slot is empty during bootstrap).
Two related fixes to the lockstep release flow + the project invariant
that prod must always run stable bytes (and dev only ever beta-or-stable).
1) tag-after-commit ordering. `./build release X.Y.Z` previously
regenerated zddc/internal/apps/embedded/* with stable labels but
tagged BEFORE folding those changes in. The tag landed on the
source-side commit (alpha-dirty embedded), and the operator was
expected to commit the embedded changes as a follow-up — which got
dropped in practice, leaving prod binaries with alpha-dirty bytes
baked in. (See the v0.0.9 re-anchor in the immediately preceding
commit for the manifestation.)
Refactor:
- _promote_stable / promote_zddc_server in shared/build-lib.sh
no longer call `git tag`. They keep their pre-flight check
(now: tag must be in HEAD's history rather than == HEAD, since
HEAD will advance after the release commit).
- Top-level ./build adds a new "Release commit + tag" block at
the end of stable cuts: stages the regenerated embedded files,
makes a `release: vX.Y.Z lockstep` commit, and tags all seven
artifacts at the new commit. Idempotent — no commit if there
are no changes.
2) bake-in invariant. Plain `./build` and `./build alpha` now
leave zddc/internal/apps/embedded/ untouched — the binary keeps
shipping whatever the last beta or stable cut wrote. `./build
beta` and `./build release` are the only paths that update
embedded bytes. Active dev iteration uses tool/dist/<tool>.html
directly; the binary's embedded copy is the default fallback,
not a workbench.
Verification on this commit:
./build → embedded mtime unchanged, no "M" lines for embedded/
./build alpha → embedded mtime unchanged, no "M" lines for embedded/
Docs updated to match in CLAUDE.md "Things that bite" + AGENTS.md
"Releasing — lockstep" + the leading help text in ./build itself.
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

Migrates from in-repo orphan `website` branch + LFS to a two-repo +
deploy-host model so source editing is fully decoupled from live state.
- Source code stays here (codeberg.org/VARASYS/ZDDC).
- Hand-edited website content moves to a separate Codeberg repo
(codeberg.org/VARASYS/ZDDC-website, cloned at ~/src/zddc-website/).
- Live site is /srv/zddc/ on the deploy host (Caddy bind-mount),
populated by ./deploy from this repo's dist/release-output/ plus
~/src/zddc-website/.
- Releases are no longer in any git history — reproducible from
<tool>-vX.Y.Z tags via `./build release X.Y.Z`. No LFS, no
Codeberg release assets.
Build/deploy split:
- ./build (no arg) is source-only; nothing in dist/release-output/
or /srv/zddc/ is touched.
- ./build alpha|beta|release seeds dist/release-output/ from
/srv/zddc/releases/ (preserving symlinks), then mutates the
channel(s) being cut on top. The bundle is always a complete
intended-live snapshot, so the verifier sees a complete world
and ./deploy --releases (rsync --delete-after) replaces live
state cleanly.
- New ./deploy wraps the rsync flow with --content / --releases
subcommands.
Docs updated to reflect the new model: CLAUDE.md, AGENTS.md,
ARCHITECTURE.md, zddc/README.md, README.md, .gitignore, shared/
build-lib.sh comments, deprecated zddc/release.sh message.

Reverts the prior CLI simplification. ./build (no arg) now does source
work only — tool dist/ + cross-compiled zddc-server binaries — and
leaves the website worktree alone. Channel/release cuts are explicit:
./build dev build (source only, no deploy)
./build alpha cut alpha (cascades nothing)
./build beta cut beta (cascades alpha → beta)
./build release [X.Y.Z] cut stable (cascades all)
Rationale: editing source shouldn't have a side-effect on the live
site. The website worktree at ~/src/zddc-website/ is what Caddy serves
in real time, so any write to it is a deploy. Treating dev iteration
as alpha-publish was confusing — the user wanted source builds and
deploys to be distinct verbs.
Mechanically: a `dev` (default) branch is added to the case statement;
the post-build matrix-index regen + channel-link verifier are
conditional on RELEASE_CHANNEL being set; dev builds skip them.

Renames build.sh → build and replaces the --release flag form with
subcommands:
./build cut alpha (default; active dev iteration)
./build beta cut beta (cascades alpha → beta)
./build release cut stable (coordinated next version)
./build release X.Y.Z cut stable at explicit version
./build help
The contract shift: there's no longer a "plain dev build that doesn't
touch channels" at the top level. Every full-stack build is a publish
action — running ./build IS active dev iteration, which is what alpha
already meant. To iterate on one tool without writing to the website
worktree, use the per-tool sh tool/build.sh (unchanged).
Output continues to land in ${ZDDC_DEPLOY_RELEASES_DIR:-$HOME/src/zddc-website/releases}
and nothing is pushed automatically. Commit + push the website branch
yourself when you want to publish. Stable cuts still tag locally on
main; tags push separately too.
Behind the scenes: the export of ZDDC_DEPLOY_RELEASES_DIR is moved
above the per-tool build.sh invocations so children inherit it. The
prior "if RELEASE_CHANNEL else write_zddc_server_stubs_all" branch is
collapsed since RELEASE_CHANNEL is always set under the new CLI.
Docs (CLAUDE.md, AGENTS.md, ARCHITECTURE.md, zddc/README.md) updated
to reference ./build everywhere; the per-tool sh tool/build.sh refs
stay (they're a separate, narrower entry point).
