feat(server): local-only tool-HTML override; remove apps URL/version fetching
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.

refactor: unified listing protocol + form-editor retirement + admin elevation
Three coordinated changes that share the same files. Common theme:
convention beats exception. Where the codebase had a bespoke wire shape
or a special-case route, replace it with the generic shape every other
client already speaks.
== Listing protocol ==
GET / Accept: application/json used to dispatch to a bespoke
ServeProjectList handler returning {name, url, title} per project — a
shape that diverged from every other directory's listing.FileInfo
response. Now:
- listing.FileInfo gains an optional `title` field (read from each
directory's own .zddc title:). Generic clients (landing, browse)
read the same shape from every URL.
- appfs.ListDirectory emits a virtual `.zddc` entry (is_dir:false,
virtual:true) when no on-disk file exists at that path and the
caller asked for ?hidden=1. Opens an editable view of the cascade
defaults; PUT-saving its bytes materialises a real file.
- The bespoke GET / JSON branch in cmd/zddc-server/main.go is gone.
The bare-root landing serve is Accept-gated: HTML requests get the
landing tool (project picker), JSON requests fall through to
ServeDirectory and get the generic listing.
- landing's fetchProjects filters the new generic shape (is_dir,
strip trailing slash) — same pattern fetchParties already used at
/<project>/archive/.
== Form editor retirement ==
`<dir>/.zddc.html` was a server-rendered form for editing per-directory
.zddc files (~900 LOC across zddceditor.go, zddchandler.go, zddc_assets.go).
Browse's YAML/CodeMirror editor (with .zddc-schema lint) already edits
the same files via the generic file-API. Two ways to edit the same data
is exception, not convention.
- Delete zddceditor.go, zddchandler.go, zddc_assets.go and tests.
- `/<dir>/.zddc.html` → 302 redirect to `/<dir>/?file=.zddc` (browse
opens the .zddc in its editor pane).
- /.profile/zddc/* namespace deleted (REST API + assets sub-route).
- Profile page's "Editable .zddc files" list links to browse.
- ServeZddcFile's 405 message + virtual-body comment point at the
browse URL instead of the dead form.
== Admin elevation (Principal model) ==
Sudo-style: admins are treated as normal users by default; opting into
admin powers is per-request and gated by a `zddc-elevate=1` cookie.
- zddc.Principal{Email, Elevated} replaces bare-email arguments on
IsAdmin / IsSubtreeAdmin / CanEditZddc. The signature change makes
the elevation gate compiler-enforced at every admin call site —
audit-fragility is gone. The empty-email short-circuit is no longer
load-bearing for elevation; Principal.gate() is the explicit check.
- handler.ACLMiddleware derives Elevated per request: bearer tokens
are implicitly elevated (CLI clients can't toggle a cookie); browser
sessions elevate only when zddc-elevate=1 is set. PrincipalFromContext(r)
is the one-call-per-site bundling helper.
- Every admin-check call site updated to pass a Principal.
- /.auth/admin (forward_auth target for the dev-shell IDE) explicitly
bypasses elevation with a synthetic-elevated Principal — different
cookie scope than zddc-server origin, documented inline.
- AccessView gains CanElevate (elevation-independent "does this email
have admin authority anywhere?") so the header toggle can render
itself for an un-elevated admin who hasn't opted in yet.
- ServeProjectList is removed; ProjectInfo + EnumerateProjects stay
for the profile page's server-rendered project list.
- MatchAppHTML stays — still used by main.go to route <dir>/<tool>.html
URLs to the apps subsystem when no real file exists.
- Test helpers carry Elevated=true by default (matches the
pre-elevation default; tests for the un-elevated gate use the
explicit form).
Go tests pass across all 14 internal packages. Browse + every other
tool rebuilds clean.

chore: retire mdedit tool — markdown editor lives in browse now
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.

perf(server): ETag + max-age=0 on embedded HTML responses
The apps subsystem previously sent Cache-Control: public, max-age=300|3600, must-revalidate but no ETag. With must-revalidate and no validator, the browser cannot return 304 — it has to refetch the full body once max-age expires. For mdedit that's 920 KB on every reload after an hour. Add a content-addressed ETag (sha256 hex prefix, 32 chars) to: - apps/handler.go's serveBody + serveEmbedded (both paths now emit ETag + handle If-None-Match short-circuit to 304) - handler/directory.go's embedded:browse fallback (mirror behavior so the bare-directory landing serves the same way) Drop max-age to 0 with must-revalidate: every page load revalidates, but a matching ETag returns 304 with empty body. Steady-state cost of a reload drops from N KB to a few hundred bytes. When the binary is redeployed, the ETag changes (content hash) and the next request returns 200 with the new bytes. Tests in apps/handler_test.go cover both paths: - TestServer_Embedded_ConditionalGET: full GET, matching INM, stale INM - TestEmbeddedETag_Stable: same bytes → same ETag, different → different Live smoke (curl against zddc-server -root /tmp/empty): GET / → 200, ETag set, body = 80919 bytes (landing.html) GET / + INM:tag → 304 Not Modified, empty body |

feat(browse): generic directory listing tool — default at folder URLs
All checks were successful
Notify chart dev on beta cut / notify-chart-dev (push) Successful in 5s
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).

feat(zddc-server): apps fetch+cache subsystem with cascade overrides
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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
