zddc-server now issues its own bearer tokens for non-browser callers
(CLI tools, scripts, downstream proxy/cache/mirror instances). No
external IDP, no JWKS rotation. Self-service flow: sign in via the
browser, visit /.tokens, click "Create token," paste the resulting
plaintext into a 0600 file, and pass --bearer-file <path> to whatever
calls back into the server.
Storage is <ZDDC_ROOT>/.zddc.d/tokens/<sha256-hex>, YAML per token
with email/created/expires/description. Filename is the *hash* of the
plaintext, never the plaintext itself — a leak of the tokens
directory exposes hashes, not credentials. Mode 0600 / 0700, atomic
writes via temp+rename. Already shielded from public serving by the
existing dot-prefix guards in dispatch and fs.ListDirectory.
ACLMiddleware now recognises Authorization: Bearer <token>. On valid
token, sets the request email from the token file and falls through
to the existing ACL chain. On any failure (unknown / expired / store
unavailable / Bearer with no validator), returns 401 — no silent
fallback to anonymous, so a misconfigured client fails loudly.
JSON API at /.api/tokens (GET list, POST create, DELETE /<id> revoke)
backs a small inline HTML self-service page at /.tokens. Users can
only see and revoke their own tokens; cross-user revoke returns 404
to avoid leaking ownership.
--no-auth (ZDDC_NO_AUTH=1) skips ACL enforcement entirely on this
instance. On master: anyone reads everything (dev / trusted-LAN /
public-read deployments). On a downstream proxy/cache/mirror: trust
upstream's filtering, don't re-evaluate ACLs locally. Implemented as
a swap to policy.AllowAllDecider; all existing handlers keep calling
AllowFromChain unchanged. Distinct from --insecure, which only
relaxes the no-root-.zddc startup check. WARN-level startup log when
--no-auth is active so accidental enablement is visible.
33 new tests covering token storage, validation/expiry/revocation,
the JSON API end-to-end, the HTML page, and the middleware-Bearer
integration including the case-insensitive prefix and expired-token
paths. Full suite + go vet clean.
Doc updates: zddc/README.md "Authentication" rewritten to cover both
auth paths and the token UI/API; AGENTS.md gains ZDDC_NO_AUTH and a
"Bearer tokens" subsection flagging the dot-prefix-shielding pre-
condition; ARCHITECTURE.md adds "Bearer token issuance" and
"--no-auth" subsections under "Server security model" with the
hash-as-filename rationale and dispatch-shielding regression-
sensitivity called out; CLAUDE.md adds a one-line summary of the new
auth topology so future agents pick it up by default.

When an HTML GET hits a directory that's the rows-dir of a registered
table — i.e. parent declares `tables: { <name>: ... }` with a valid
spec, OR the default-MDL fallback applies at archive/<party>/mdl/ —
ServeDirectory now 302s to <parent>/<name>.table.html so users land
on the table view instead of a bare browse listing of the row-yaml
files. JSON GETs on the same URL fall through unchanged so the table
client can still enumerate row files.
Detection reuses RecognizeTableRequest: synthesize the equivalent
.table.html URL from the directory request and let the existing
recognizer apply its operator-vs-default-vs-missing-spec rules. No
duplicated validation.
Updates main_test.go's TestDispatchSlashRouting to expect the new
behavior on archive/<party>/mdl/.

Add a virtual-URL alias so the existing form-based .zddc editor is
reachable at the natural directory location (<dir>/.zddc.html) in
addition to the legacy /.profile/zddc/edit?path=<dir> entry. Both
flow through the same renderZddcEditor body — same template, same
gate, same form-posts-to-/.profile/zddc semantics.
Wiring:
- IsZddcEditorRequest(urlPath) reports whether the URL ends with
the .zddc.html leaf (case-fold not needed; .zddc is itself case-
sensitive on disk).
- ServeZddcEditorAtPath strips the leaf, resolves the parent dir,
asserts the dir exists, gates on hasAnyAdminScope, calls the
shared renderer.
- The dispatcher routes IsZddcEditorRequest URLs BEFORE the dot-
prefix segment guard (which would otherwise 404 the .zddc.html
leaf). The route is method-gated GET-only; mutations still go
through PUT/POST/DELETE on <dir>/.zddc via the file API.
Permission model unchanged from the /.profile entry: hasAnyAdminScope
gates visibility of the editor itself; CanEditZddc decides whether
the form is interactive or read-only at the requested directory.
Subtree admins can still inspect ancestor cascade ACLs (intended
since the cascade is what determines their authority).
Test (TestDispatchZddcEditorAtPath): root admin opens project /
working/ / deployment-root editors; non-admin and anonymous both
404; missing directory 404; trailing-segment-after-leaf 404.

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.

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.

Add a new "The inherit: directive" subsection in zddc/README.md
under "Access control: the .zddc cascade" describing the directive's
purpose (vendor-folder reset, regulated subtrees), the four behaviour
points (grants, roles, admins, WORM), the strict-mode refusal under
NIST AC-6, and the tracer's visibility. Cross-link from the "How a
request is evaluated" walkthrough so a reader who's looking up the
core walk can find the fence behaviour without having to scan further.
Update the "Patterns that look secure but aren't" trap #1 (same-level
allow + deny "*@company.com") to recommend inherit: false as the
preferred fix, with a worked-example .zddc snippet alongside the
broken one. The two-level gate-and-reallow pattern remains as a
fallback for federal-track deployments where inherit: is refused.

The cascade tracer's JSON response now carries:
- Top-level `cascade_mode` (string): the active mode (delegated /
strict). Helps reviewers correlate the visible_start with the mode.
- Top-level `chain.visible_start` (int): chain.VisibleStart(leaf, mode)
— the lowest level whose grants the leaf can see, accounting for any
inherit:false fence in delegated mode (always 0 in strict mode).
- Per-level `inherit` (*bool, omitempty): the level's explicit inherit
value, nil when absent. A reviewer can scan the levels and see which
one fences ancestors.
The level's `exists` flag now also fires for `permissions:` and
`inherit:` entries (previously it only checked Allow/Deny/Admins),
so the response correctly reflects modern .zddc files that use the
permissions map.
Test: TestServeProfileEffectivePolicy_InheritFence builds a vendor-
folder layout, asks the tracer about a my-company user, confirms
decision=false, visible_start=1 (fence at /Vendor/), leaf.Inherit=
&false, root.Inherit=nil.

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)

Three pieces wire the per-party Master Deliverables List as the default
view at archive/<party>/mdl/:
1. **Dispatcher redirect.** GET (and HEAD) on
<project>/archive/<party>/mdl/ (case-fold on archive and mdl) now
302 → <project>/archive/<party>/mdl.table.html. Non-archive paths
and deeper mdl/ paths fall through unchanged.
2. **Default-spec fallback in RecognizeTableRequest.** When a request
matches archive/<party>/mdl.table.html and no operator-supplied
tables: { mdl: ... } declaration covers it, the handler returns a
recognised request anyway. Operator declarations still win — and a
typo'd declaration pointing at a missing file yields 404 (not a
silent fallback).
3. **Static-file fallback for the spec yaml.** GET archive/<party>/
mdl.table.yaml and archive/<party>/mdl.form.yaml return embedded
default bytes (default-mdl.{table,form}.yaml in the handler package)
when no operator file exists at that path. Operator files always
win because the dispatcher's os.Stat finds them before reaching the
IsDefaultMdlSpec branch.
The defaults use ZDDC vocabulary: tracking, title, discipline, type,
plannedRevision, plannedDate, status (DFT/IFR/IFA/IFC/AFC/AB), owner,
notes. Operators override per-party by writing
archive/<party>/{mdl.table.yaml,mdl.form.yaml} and a tables: { mdl: ... }
entry in the party's .zddc.
Tests:
- 4 dispatcher redirect cases (success, case-fold mdl, case-fold archive,
deeper-path skip, non-archive skip)
- 6 tablehandler cases (default fires at archive/<party>/, operator
override wins, scope check, embedded yaml served, operator yaml wins,
scope check on yaml fallback)

ListDirectory now appends a synthetic <viewer-email>/ entry when the
listed path is exactly <project>/working/ (depth 2, case-fold) and no
real directory there matches the viewer's email under any case.
The entry has IsDir=true and a new Virtual=true flag on
listing.FileInfo (omitempty in JSON so existing clients that don't
know the field continue to render it as a regular folder). A first
write to that path materialises a real folder via the existing
auto-own pipeline (EnsureCanonicalAncestors → WriteAutoOwnZddc),
after which subsequent listings drop the synthetic entry naturally.
Anonymous viewers, listings outside working/, and listings inside a
deeper working/ subdirectory all skip the synthetic entry.
Six tests cover: appears-when-missing, suppressed-when-real-exists
(case-fold), anonymous-no-entry, staging/-no-entry, deep-working-no-
entry, and pre-existing-PascalCase-Working/ still triggers it.

When a folder is created under <project>/staging/ whose name parses as a
ZDDC transmittal folder (YYYY-MM-DD_<tracking> (<status>) - <title>) and
whose tracking number contains -TRN- or -SUB-, also create the same-
named folder under <project>/working/ as a drafting space for staff.
The mirror is one-way and one-shot: created at staging-mkdir time only.
Renames and deletions of either side are not propagated. The
transmittal client orchestrates cleanup at issue time (move files to
archive/<recipient>/issued/, then delete both staging and working
siblings) — the server stays out of that decision.
-MDL- tracking deliberately skips the mirror; MDL deliverables live in
archive/<party>/mdl/ rows, not via the working↔staging pairing.
Implementation: mirrorStagingToWorking() in fileapi.go, called after a
successful serveFileMkdir. EnsureCanonicalAncestors handles working/'s
own auto-own .zddc; the mirror folder gets its own creator-grant on top.
Six new tests cover -TRN-/-SUB- mirror, -MDL- skip, non-transmittal
name skip, deep-path skip, and idempotency over a pre-existing sibling.

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.

The transmittal-folder grammar was duplicated as a private regex inside
the archive package. Replace the local regex with calls to the shared
parser in zddc/internal/zddc/folder.go so the grammar lives in one

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.

The .archive virtual prefix is now project-scoped at exactly one URL
depth: any /<project>/<sub>/.../.archive/... gets a 301 to the
canonical /<project>/.archive/.... The dispatcher does this before
calling the handler; query strings are preserved (the browser handles
the fragment automatically). .archive is also GET/HEAD-only — anything
else returns 405 with Allow: GET, HEAD, ahead of the file API.
Why: offline-built HTML files reference siblings as
"../.archive/<tracking>.html" from arbitrary depths. All of those refs
should converge on a single stable URL per (project, tracking) so
external links and bookmarks don't fork by entry point.
Permissions now follow the resolved file, not .archive itself.
.archive is a virtual surface — it has no on-disk directory and no
.zddc of its own, so gating it as if it did is wrong. Two gates only:
- Resolve: only the per-target file's ACL chain decides. A user
explicitly allowed at one transmittal folder but denied at the
project root can still fetch tracking numbers that resolve there.
Per-target denial returns 404 (not 403) so existence doesn't leak.
- Listing: filter entries by per-target ACL. If the project bucket
has zero indexed entries → 404 (unknown / empty project, indistinguishable
from a probe). If the bucket is non-empty but the caller can read
no entries → 403 (existence-leak guard: don't confirm an inaccessible
project's archive exists). Otherwise → 200 with the filtered subset.
The listing endpoint is now content-negotiated like ServeDirectory:
Accept: text/html serves the embedded `browse` SPA bytes (with the
embedded ETag and X-ZDDC-Source: embedded:browse); Accept:
application/json returns the JSON entry array (with content-hash ETag
and 304 short-circuit). Vary: Accept set on both. The browse SPA's
auto-detect path-fetch then renders the archive entries as a sortable,
filterable flat list at /<project>/.archive/.
ServeArchive's signature is now (cfg, idx, w, r, project, filename) —
the dispatcher hands the normalized project string in directly, so
projectFromContextPath is gone. Old behavior was to derive project
from contextPath inside the handler; with the upstream redirect that's
redundant and the handler's preconditions are simpler.
Tests: archivehandler_test.go rewritten around the new semantics;
added per-target-only resolve, project-root-deny + per-target-allow
rescue, listing 403/404 distinction, JSON/HTML content-negotiation,
and conditional GET. main_test.go gains TestDispatchArchiveRedirect
(deep paths, query preservation, already-canonical no-op) and
TestDispatchArchiveMethodGate (PUT/POST/DELETE → 405).

The fsnotify watcher only sees events the local kernel generates, so on
SMB/CIFS-backed roots (Azure Files) writes from any other client are
invisible — the archive index would silently miss them until pod
restart. Add two backstops:
1. Periodic full re-walk via Index.Rebuild on a configurable interval
(--archive-rescan-interval / ZDDC_ARCHIVE_RESCAN_INTERVAL, default
60s, 0 to disable). Atomically swaps ByProject under the existing
RWMutex; concurrent reads stay safe.
2. Admin-only POST /.profile/reindex that triggers an immediate rebuild
and returns {duration_ms, project_count, tracking_count}, for the
"I just dropped 50 files and don't want to wait" case. Gated by
IsAdmin with the same 404-on-non-admin pattern as the other admin
sub-resources.
Tests: TestRebuild_PicksUpAddsAndDrops covers add+drop semantics and
returned counts; TestServeProfileReindexPOST covers the happy admin
path; matrix entries cover the gate (anonymous/non-admin → 404, admin
GET → 405 method-not-allowed since the route is POST-only).

Refreshes //go:embed bytes off fe28a73. Dev image now ships the new
tables renderer (handler-local embed at handler/tables.html) plus
build-label refresh on the six cascade-served tools.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Resolved `.archive/<tracking>.html` URLs now serve the target file's
bytes inline via http.ServeFile with Cache-Control: no-cache, replacing
the previous 302 redirect to the per-transmittal URL.
Why: external links like `.archive/<tracking>.html#section` are meant
to track the latest revision. A redirect exposes the snapshot URL — any
forwarded link then pins to that snapshot instead of "latest." Serving
in-place keeps the `.archive/` URL stable as the resolver's "current"
target moves over time.
Cache-Control: no-cache is intentional. Each load revalidates against
the on-disk file's Last-Modified/ETag, so when a new revision lands the
resolver picks it and the browser refetches transparently.
ACL is unchanged: enforced on both the `.archive` context directory and
the resolved target file (per-target denial returns 404, not 403, to
avoid disclosing that a tracking number exists in a hidden subtree).
archivehandler_test.go status expectations updated 302 → 200; fixture
bodies adjusted for body-content verification of the in-place serve.

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.

Refreshes the //go:embed bytes off 3115e38. Dev image (ZDDC_REF=main)
now ships the file API and verb-based RBAC.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.

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.

Ship a second parity-tested Rego policy that flips the cascade's
leaf-allow-overrides-parent-deny rule for NIST AC-6 conformance.
Standard cascade (existing access.rego, mirrors internal Go evaluator):
Bottom-up walk; first explicit match wins; deny-first within a level.
A leaf-level allow CAN override an ancestor's deny. This is the
cascade's intentional delegation property — a project-owner who
re-allows a previously-denied collaborator works as expected.
Federal mode (new access_federal.rego):
Any deny anywhere along the chain is absolute. An allow only matters
if no level (any depth) has denied the same email. Required by
NIST AC-6 default expectations: a central admin's deny at the root
must be unbypassable by a tenant who controls a subtree's .zddc.
Operators run real OPA with this Rego and point ZDDC_OPA_URL at it;
the internal Go evaluator stays on the commercial cascade. The
toggle is "which policy does your OPA evaluate," not a knob inside
zddc-server.
Surfaced via --print-rego flag:
zddc-server --print-rego # standard (default)
zddc-server --print-rego=standard # same
zddc-server --print-rego=federal # AC-6 strict variant
Parity test (federal_parity_test.go) compiles both Regos and asserts:
* They AGREE on every cascade scenario where no ancestor-deny
intersects a leaf-allow (most cases).
* They DISAGREE — by design — on the three scenarios where the
AC-6 rule differs:
- "leaf allows what parent denied" → standard allows, federal denies
- "deep leaf re-allows after middle deny" → same
- "glob deny at root + specific allow at leaf" → same
Cross-checks the divergence flag explicitly so any future change that
accidentally collapses the two policies fails the test.
Closes the AC-6 row of the federal-readiness gap analysis (now marked
"partially complete" in zddc/README.md — the full bullet would be a
built-in --policy-mode=federal toggle that also flips the in-process
Go evaluator).
Production binary unchanged at 13.1 MB (Rego files embedded as bytes;
OPA library remains test-only).

Eliminates the manual cascade-trace ritual when debugging "why can't
alice see /Project-X" reports. New endpoint returns the resolved
policy chain plus the active decider's verdict in JSON:
GET /.profile/effective-policy?path=/Project-X/sub/&email=alice@…
Response shape:
{
"path": "/Project-X/sub/",
"email": "alice@…",
"decision": true,
"decider_kind": "*policy.InternalDecider",
"chain": {
"has_any_file": true,
"levels": [
{"index": 0, "zddc_path": "/.zddc", "exists": true,
"acl": {...}, "admins": [...],
"matches_email": false, "decision_at_level": "no_match"},
{"index": 1, "zddc_path": "/Project-X/.zddc", "exists": true,
"acl": {...}, "matches_email": true, "decision_at_level": "allow"}
]
}
}
Per-level email matching reuses the same MatchesPattern code the live
evaluator uses, so the trace can never disagree with the actual
verdict — and when ZDDC_OPA_URL points at an external OPA, the
decision goes through that OPA, making the endpoint a useful smoke
test for OPA wiring too.
Admin-only via the existing /.profile gate (404 to non-admins).
Required params; 400 if either is missing or path doesn't escape ROOT.
Test coverage:
* TestServeProfileGateMatrix: anonymous → 404, non-admin → 404,
admin without params → 400 (gate cleared, validator rejected)
* TestServeProfileEffectivePolicy: full payload-shape assertion
against a worked-example fixture (closed project where alice is
allow-listed but bob is not)
Also fixes pre-existing doc drift: README's "Admin Debug Page"
section referenced /.admin/whoami|config|logs but the actual code
mounts /.profile/* (the rename predates this PR; the doc was stale).
Closes the "/.admin/effective-policy debug endpoint" item from the
federal-readiness future-work list.

The previous keyForURL stripped default ports (:443 for https, :80
for http) and omitted the scheme, so:
http://example.com/x.html ──┐
https://example.com/x.html ──┴──→ same cache entry (collision)
https://example.com/x.html ──┐
https://example.com:443/x.html ──┴──→ same cache entry
This was a defensible HTTP convention but a real correctness issue
on reverse-proxy stacks where http and https legitimately serve
different bytes for the same path, or where two upstreams share a
host but answer on different default ports.
New layout: <scheme>/<host>[:<port>]/<path>. Full origin tuple in
the key, no port stripping, scheme segregation. Examples:
https/zddc.varasys.io/releases/archive_stable.html
https/example.com:8443/x.html
http/example.com/y.html (distinct from https/example.com/y.html)
Operators retain the "ls _app/ to inspect what's cached" affordance
they relied on; they just see one extra directory layer (scheme
first, then host).
Tests:
* Updated TestKeyForURL to assert the new layout for every
previously-covered case
* New TestKeyForURL_NoCollisions explicitly asserts that the
dimensions previously collapsed (default-port↔bare, http↔https,
different non-default ports) now produce distinct keys
Doc references to the cache layout under <ZDDC_ROOT>/_app/ updated
in zddc/README.md (3 mentions).
NOTE: existing _app/ caches under the old layout will be ignored
on first request after upgrade — entries will be re-fetched and
written to the new path. Operators can `rm -rf <ZDDC_ROOT>/_app`
during the upgrade window if they prefer not to have orphans.

The TLS configuration was using Go stdlib defaults — secure for typical
commercial use, but federal evaluators need an explicit cipher
allowlist they can map to a FIPS-validated implementation. Pin the
cipher and curve lists to NIST SP 800-52 Rev. 2 § 3.3 conformant
values:
Ciphers (TLS 1.2):
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305
TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305
Curves: X25519, P-256, P-384
MinVersion: TLS 1.2 (already set; 1.3 used when negotiated)
TLS 1.3 cipher selection is not operator-controllable in Go stdlib
(the runtime picks from a fixed AEAD-only set); all of those
already meet the federal bar so no change needed there.
Also adds HSTSMiddleware emitting `Strict-Transport-Security:
max-age=31536000; includeSubDomains` when zddc-server is itself
terminating TLS (ZDDC_TLS_CERT != none). Behind an upstream proxy
terminating TLS the proxy is responsible for HSTS, so the middleware
only wraps the chain when useTLS=true.
Test coverage:
* TLSConfig(none) returns nil + useTLS=false
* TLSConfig(selfsigned) sets the exact NIST allowlist
* Negative test asserting weak ciphers (CBC, RC4, 3DES, RSA-key-
exchange) are NOT in the list — guardrail against regressions
Federal-readiness gap analysis updated: this control is now partially
complete. OCSP stapling and CT-log inclusion remain on the list for
full DoD STIG conformance.

Three docs aligned with the preceding three feature commits.
zddc/README.md
--------------
Major overhaul of the access-control narrative. The previous "three-
tier" example table was misleading: it claimed a project-level
allow-list "restricts" access under a parent wildcard, when actually
the cascade is additive (a non-team employee falls up to root and
matches *@company.com). Operators reading the old docs would build
deployments that looked locked-down but leaked across the company.
New sections under "Access control: the .zddc cascade":
* Step 1: starter .zddc — leads with the public-by-default warning
and the --insecure escape hatch
* How a request is evaluated — bottom-up walk with code citations
* Glob patterns — @-boundary rule
* When the cascade helps and when it fights you — the asymmetry
between adding strangers (easy) and excluding insiders (hard)
* Pick your layout — decision matrix for common shapes
* Worked example: paired open/closed projects + third-party archive
— full layout with trace table for two representative users
* Patterns that look secure but aren't — anti-patterns including
same-level allow+deny shadow, leaf-allow-doesn't-restrict,
apps:-as-UI-mount
* Trust model and invariants — auth boundary, subtree authority,
root-only escalation gate
* Trust boundary — network isolation requirement, anonymous
information disclosure on /, audit-log integrity
* Debugging permissions — manual cascade trace
* Directory visibility / Reserved hidden segments
* How to verify in 5 minutes — recipe with negative anti-pattern test
* Federal-readiness gap analysis — bulleted with NIST control refs
* External policy decider — OPA wire format, deployment shapes,
failure modes
* OPA decision cache — TTL semantics, knobs
* Reference Rego policy — --print-rego, parity test rationale
* Caching and ETags — content-hash story, why not server-side
* Future work
Plus env-var table updates for ZDDC_INSECURE, ZDDC_OPA_URL,
ZDDC_OPA_FAIL_OPEN, ZDDC_OPA_CACHE_TTL; CORS narrative reflects
default-empty.
ARCHITECTURE.md
---------------
New "Server security model" section between Form Renderer and CSS:
cooperating layers (auth / policy decider / cascade / tool-rooted
view / reserved prefixes / audit log), commercial-vs-federal trust
model side-by-side, why the tool-rooted view matters for third-party
containment.
AGENTS.md
---------
Two new env-var rows (ZDDC_OPA_URL, ZDDC_OPA_CACHE_TTL); ACL line
sharpened with cascade rules + cross-reference; ZDDC_CORS_ORIGIN
description updated for default-empty.

Phase 2 enhancements to the policy decider, plus listing-level ETags
that benefit every deployment regardless of decider mode.
Reference Rego policy
---------------------
internal/policy/rego/access.rego mirrors InternalDecider's semantics
exactly — bottom-up walk, deny-first within a level, default-deny when
HasAnyFile=true, glob matching with @-boundary semantics (special-cased
bare "*" because OPA's glob.match treats empty delimiters
inconsistently for that pattern).
Embedded into the binary via go:embed; --print-rego dumps it to stdout
so federal customers standing up an external OPA can use it as a
parity-tested baseline:
zddc-server --print-rego > /etc/opa/policies/zddc-access.rego
Parity test runner
------------------
parity_test.go imports the OPA Go module as a TEST-ONLY dependency
(github.com/open-policy-agent/opa@v0.70.0). Every fixture from the
internal Go evaluator's test set runs through both implementations;
any divergence fails CI. The test-only import means production
binaries (built by `go build ./cmd/zddc-server`) stay OPA-free —
release-flag binary size unchanged at ~13 MB.
The parity test caught a real bug on first run: bare "*" patterns
didn't match through OPA's glob.match with empty delimiters. Fixed
in access.rego with a special-case rule. This is exactly the kind of
subtle drift the parity guard exists to catch.
External-mode decision cache
----------------------------
HTTPDecider is now wrapped in a cachingDecider with a default 1s TTL.
Bursty patterns like .archive listings (one OPA round-trip per entry
before, one per (email, decision-input) tuple per TTL window after)
amortize cleanly. Verified: 20 identical /D/ requests produce 1 OPA
hit with cache, 40 hits without (each listing makes 2 ACL queries).
ZDDC_OPA_CACHE_TTL knob (default 1s) lets operators tune. 0 disables.
1s matches the fsnotify watcher debounce window — staleness is
bounded the same way other policy-edit propagation already is.
Internal mode unchanged; the in-process Go evaluator is already
cheaper than a cache lookup would be.
Listing ETags
-------------
GET / (project list) and GET /<dir>/ (directory listing JSON) now
carry content-hash ETag + Cache-Control: private, max-age=0,
must-revalidate. SHA-256 of the rendered JSON, truncated to 16 hex
chars (64 bits — collision risk on a listing of any realistic size
is vanishingly small).
Server-side caching deliberately not added: it would require
mtime-based invalidation, and Azure Files SMB mounts (a common
deployment substrate) don't support fsnotify reliably. The
content-hash ETag delivers the bandwidth savings (304 on identical
fetches) without depending on watcher correctness — the hash is the
actual response, so it can't lie about staleness regardless of
underlying watcher behavior.

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.

Two safe-by-default flips, both opt-out via explicit acknowledgement.
1. --insecure / ZDDC_INSECURE=1: zddc-server now refuses to start when
no <ZDDC_ROOT>/.zddc exists. With no .zddc anywhere in the chain,
AllowedWithChain falls through to "HasAnyFile=false → allow" and
the tree is publicly accessible to anonymous callers — almost never
what an operator wants on a fresh deployment, and previously a
silent footgun. The flag is the escape hatch for deliberately-
public archives (no .zddc anywhere by design).
2. ZDDC_CORS_ORIGIN now defaults to empty (CORS disabled) instead of
the canonical "https://zddc.varasys.io". The embedded-tools install
path serves tools and data same-origin, so the default never needed
to permit cross-origin XHRs from a third-party host. Every deployment
was implicitly trusting zddc.varasys.io to make authenticated XHRs
on behalf of every logged-in user; if that origin were ever
compromised, the blast radius extended to every customer server.
Operators who deliberately use the CDN-bootstrap pattern or self-
hosted tools at a different host now set the value explicitly.
Helm chart values updated accordingly: prod default is empty; dev
keeps localhost:8000 for tool-iteration workflows. Existing deployments
that depended on the old defaults will need to either set the value
explicitly or pass --insecure.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The recent history rewrite (squash of 4 thrash CI commits) made the
chart's previous appVersion (0.0.16-beta-8df0def) reference a now-
dangling commit. The dev pipeline failed clone "remote ref not
found" until we re-bumped to a SHA in the new history.
Re-cut beta with the new HEAD parent (ae75855) so notify-chart-dev
rewrites the chart's appVersion to a SHA the BMCD dev pipeline can
actually fetch. Combined with the Dockerfile clone-via-fetch fix in
tnd-zddc-chart 86c5758 (handles bare SHAs), the dev pipeline should
build cleanly.
Two related operational improvements:
1. HTTP timeouts on http.Server (ReadHeaderTimeout 10s, ReadTimeout +
WriteTimeout 60s, IdleTimeout 120s). Caps slow-client connection
hold time; closes the slowloris vector. Listing + tool-HTML
responses complete in milliseconds even with gzip, so 60s is
generous for legit traffic.
2. --access-log defaults to <ZDDC_ROOT>/.zddc.d/logs/access-<host>.log
instead of stderr-only. The server auto-creates the parent tree
(mode 0750), so a fresh deployment gets an audit trail without
operator setup. Every JSON record carries a `host` field (from
os.Hostname) — multi-replica deployments share the .zddc.d/logs/
directory but write to per-host filenames, and downstream
aggregators can disambiguate via the host field.
Opt-out: --access-log= (explicit empty). Distinguishing "unset"
from "set to empty" follows the same pattern config.go already
uses for --cors-origin.
Live verification:
$ zddc-server -root /tmp/r -addr 127.0.0.1:8765 -tls-cert none -insecure-direct
$ curl http://127.0.0.1:8765/
$ ls /tmp/r/.zddc.d/logs/
access-bizon.log
$ tail -1 /tmp/r/.zddc.d/logs/access-bizon.log
{"time":...,"level":"INFO","msg":"access","host":"bizon",...,"email":"anonymous","method":"GET","path":"/","status":200,...}
$ zddc-server -root /tmp/r ... -access-log= # opt-out
$ ls /tmp/r/.zddc.d/ # empty: no logs/ created
Bake into the dev binary:
- ETag + max-age=0 on embedded HTML (304s on repeat loads)
- gzip compression middleware (~75% wire-size reduction)
- vendored jszip + docx-preview in archive/transmittal/classifier
- tee'd file-based access log via --access-log
Add --access-log <path> (env ZDDC_ACCESS_LOG). When set, every access-
log record is written as a JSON line to the configured file in
addition to the existing slog.Default() stderr output. Empty (default)
keeps the prior behavior — stderr only.
Rotation via gopkg.in/natefinch/lumberjack.v2:
100 MB per file, 10 backups, 90-day max age, gzip rotated files.
Operator usage (e.g. behind a Caddy/quadlet stack):
zddc-server --access-log /srv/.zddc.d/logs/access.log ...
Architecture:
AccessLogMiddleware now takes an optional *slog.Logger. main.go wires
it via setupAccessAuditLog() which builds a slog.JSONHandler over a
lumberjack rotator. Stderr emission stays via slog.Default(); the
audit logger gets the same fields in line-delimited JSON, the format
every standard log shipper (Vector, Loki, fluentbit, journalbeat)
parses natively.
Tests cover the audit logger receiving the same email/path/status
fields as the stderr stream.
Add github.com/klauspost/compress/gzhttp wrapper around the request
handler. With MinSize(1024), responses ≥ 1 KB get gzip-encoded when
the client advertises Accept-Encoding: gzip; smaller bodies + 304
Not Modified pass through unchanged.
The wrapper auto-appends Vary: Accept-Encoding (compatible with the
existing Vary: Accept on directory.go's content-negotiated path).
Live-tested against zddc-server -root /tmp/empty:
GET / w/ Accept-Encoding: gzip → 20.9 KB compressed (was 80.9 KB
uncompressed). 74% reduction.
Decompresses cleanly back to the original bytes.
Helps every code path that bypasses Caddy: devshell pods, local dev
binaries, tests, anywhere zddc-server is hit directly. Production
behind Caddy already had compression at the proxy layer; this just
makes the Go server self-sufficient.
Tests in cmd/zddc-server/main_test.go cover:
- large body + Accept-Encoding → compressed + Vary header
- small body → not compressed (under MinSize)
- no Accept-Encoding header → plain bytes
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
GET / and GET /index.html previously enforced the root .zddc's
top-level acl: gate before serving the landing page. On a deployment
where only specific emails are allowed at root, anonymous (and
unauthorized) callers got 403 — they couldn't even see the project
picker that would tell them which projects were available to them.
Make the landing page public:
- cmd/zddc-server: drop the AllowedWithChain gate from the
apps.Serve("landing") branch; drop it from the IsDir branch when
urlPath == "/".
- handler/directory.go: matching bypass for ServeDirectory at the
root path (covers Accept: application/json and the case where a
real /index.html exists on disk).
Per-project ACL is preserved end-to-end:
- fs.ListDirectory continues to filter sub-entries per email, so
anonymous callers see only projects whose .zddc allows them.
- Subdirectory requests still hit the ACL gate.
Regression test in handler/directory_test.go covers all four cases
(anonymous public, anonymous filters out private, admin sees both,
anonymous still 403 on private subdir). Full go test ./... passes.
Bake the standardized headers + archive bugfix + browse refactor
into the dev binary. Triggers notify-chart-dev → bumps tnd-zddc-chart
develop with appVersion=0.0.16-beta-<sha>.
Bake the latest dev cut of all six tools into zddc/internal/apps/embedded/
so the dev image (built from main) ships the new browse filter UI +
vendored JSZip. Triggers notify-chart-dev which bumps the chart's
develop branch with appVersion=v0.0.16-beta-<sha>.
Three issues from initial v0.0.12 dev/prod testing:
1. Online listings empty.
directory.go was missing Vary: Accept on its responses, so
browser/CDN cached the HTML response (the embedded browse.html)
and served it again when browse's JS later fetched the same URL
with Accept: application/json. JSON parse failed, autoDetect
returned null, empty state showed. Adds Vary: Accept on both
branches and changes browse.html cache-control to no-cache so
deployed updates land immediately.
2. Top-level folder rows tall, shrink as subtree expands.
The .browse-table had flex:1 in a flex column. <table> in flex
doesn't reliably distribute height across rows — with few rows,
each row stretched. Wrap the table in a div with overflow:auto
and drop flex:1 from the table itself.
3. Recursive expand/collapse.
Shift-click (or alt-click) on a folder now expand-all or
collapse-all its subtree. Plain click still toggles just that
folder. Implementation: tree.expandSubtree() walks BFS, loading
each level's children in parallel, re-rendering between levels
so the user sees progress. tree.collapseSubtree() recursively
marks the subtree collapsed (children stay loaded for instant
re-expand).
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).
The zddc-server-v0.0.9 (and sibling) tags previously pointed at a
commit whose embedded versions.txt + tool HTMLs still carried
alpha-dirty labels — the cut process regenerated these in the
working tree but never folded them into the tagged commit. The
binary built from that tag (used by tnd-zddc-chart's prod
Dockerfile) embedded the alpha labels.
This commit folds the stable-labeled artifacts in. The seven
v0.0.9 tags are force-moved to point here so future binary builds
from `ZDDC_REF=stable` get clean stable bytes baked in. The
old commit (a02a26d) remains in history; just no tag references
it anymore.
Sustainable fix to ./build's release flow (commit before tag,
skip embedded mutation on plain dev/alpha cuts) is a separate
follow-up — this commit only fixes the in-flight state.
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.

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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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).

Moves website source + release artifacts off `main` and into a new
orphan branch named `website` in this same Codeberg repo. A `git worktree`
of that branch — typically at ~/src/zddc-website/ — is what the system
Caddy now bind-mounts and serves at zddc.varasys.io. Decoupling source
from the live site means editing source can no longer accidentally
affect what's published.
Layout going forward:
- ~/src/zddc/ — main worktree (this branch, source only).
- ~/src/zddc-website/ — git worktree of the `website` branch:
hand-edited content + LFS-tracked release
artifacts (server binaries) + regular-git
HTML tool releases + symlinks.
- Caddy bind-mount swapped: ~/src/zddc/website → ~/src/zddc-website
(quadlet at /etc/containers/systemd/caddy.container, restarted).
Build pipeline now writes releases to
${ZDDC_DEPLOY_RELEASES_DIR:-$HOME/src/zddc-website/releases}.
- build.sh: RELEASES_DIR points at the env var
- shared/build-lib.sh: promote_release honors the env var, falls
back to the legacy in-repo path so any
standalone single-tool release on a checkout
that still has website/ keeps working
- freshen-channel: passes ZDDC_DEPLOY_RELEASES_DIR through to
the worktree-based build
Docs (CLAUDE.md, AGENTS.md, ARCHITECTURE.md, .gitignore) updated for
the new layout. The 51 MB of website/ blobs stays in main's history
(no force-push); over time Codeberg's GC will pack them down.

Restructures the version picker on the releases page so channel
mirrors are first-class, selectable options:
Channels (mutable URLs)
stable — currently v0.0.8 ← default selection
beta — tracks stable
alpha — tracks stable
Pinned versions (immutable URLs)
v0.0.8
v0.0.2
v0.0.1
Picking "stable" now rewires every download link on the page to the
*_stable.html (HTML tools) or zddc-server_stable_<plat> (binary)
channel-mirror URL — the kind a user wants to copy + bookmark for a
"latest stable" reference. Same for beta and alpha. Picking a pinned
vX.Y.Z still rewires to immutable per-version URLs.
Removed the separate "Or pick a channel" chip-pill row that previously
sat under the picker. The dropdown is now the single control; chips
duplicated functionality and added visual noise. The .channel-chips
CSS rules in website/css/style.css come out with them.
Static defaults (without JS) now use the stable channel mirror URLs
too, so both copy-from-source and JS-rewire produce the same outcome
for users who want stable. The page works end-to-end with JS off.
Embedded snapshots refreshed.

Two issues from one session:
* File tree: ZDDC-conforming filenames render as a single line
even though the JS already produced two-div markup (filename-main +
filename-secondary). Cause: .tree-row__label was display:flex
(row-direction), so the two divs laid out side-by-side. Fix: wrap
each label's text in a new .tree-row__name span styled
flex-direction:column. Both file and folder code paths use the
same wrapper now; non-ZDDC entries collapse to a single
.filename-main line so typography stays consistent across the tree.
Tested by injecting a ZDDC filename into a mock directory and
asserting filename-secondary's bounding-box top is below
filename-main's bottom.
* Toast UI Editor was unreadable in dark mode. Toast UI ships with
light-only chrome; its .toastui-editor-md-container has color #222
on a transparent bg, so when mdedit's dark theme rendered the
surrounding pane in #1e1e1e the editor text fell on near-black
background → effectively invisible. Fix: add CSS overrides in
mdedit/css/editor.css that target the editor's load-bearing
surfaces (md-container, md-preview, ww-container, ProseMirror,
toolbar, mode-switch tabs, popups) and apply var(--bg) /
var(--text). Toolbar icons get a filter:invert(0.85) hue-rotate
to flip the sprite-baked dark glyphs. Both manual override
(data-theme="dark") and OS-pref auto fallback (prefers-color-scheme)
are covered. Tested by computing contrast ratios on every editor
surface in dark mode — all came in at 10:1+ (well above WCAG AA's
4.5:1).
Embedded snapshots refreshed to current main HEAD's dev build label.

A machine-only HTTP endpoint that returns 200 if the request's
X-Auth-Request-Email is in the root .zddc admins: list, 403 otherwise.
No body, no redirect — pure authorization decision intended to be
polled by an upstream proxy's forward_auth directive.
The motivating use case is gating /devshell/* (code-server) in the
dev-shell pod on root-admin status before the request ever reaches
code-server, which has no built-in ACL of its own. zddc-server's
own routes keep the existing .zddc cascade ACL and don't go through
this endpoint.
Reuses zddc.IsAdmin (one cached map lookup) so the check is cheap
enough to call on every request. Edits to /srv/.zddc propagate via
the existing fsnotify watcher's policy-cache invalidation.
Tests cover empty email, non-admin, admin, and the bootstrap state
where no root .zddc exists (deny everyone — the safe default).
Docs: zddc/README.md "Forward-auth target for upstream proxies"
section + AGENTS.md notes bullet.

First lockstep cut. All six tools (5 HTML + zddc-server) at the same
version. zddc-server jumped from 0.0.7 → 0.0.8; HTML tools jumped from
0.0.2 → 0.0.8 (the coordinated next-stable rule picks max-tag + 1, so
HTML tools skip ahead in lockstep with the binary).
Tags created:
archive-v0.0.8
transmittal-v0.0.8
classifier-v0.0.8
mdedit-v0.0.8
landing-v0.0.8
zddc-server-v0.0.8
All tags point at 9fce18c (the source-state commit).
Artifacts under website/releases/:
- 5 per-version HTML tool files (immutable real bytes)
- 4 zddc-server binaries × 5 cascade levels (per-version + 4 symlink
levels) per platform = 20 binary entries per platform × 4 platforms
- 6 channel/per-version stub HTML pages for zddc-server (matrix-cell
download fan-out)
- All HTML tool channel mirrors updated to track v0.0.8
- Matrix index regenerated with v0.0.8 as current stable
channel-link verification: 30 link(s) ok
First time the verifier runs in non-bootstrap mode (zddc-server stable
chain anchored).

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 command-line flags to zddc-server alongside the existing env vars.
Each setting can be set via --<flag-name> or ZDDC_<NAME>; the flag wins
on conflict, the env var wins over the hard-coded default.
--root / ZDDC_ROOT (now defaults to CWD if both unset)
--addr / ZDDC_ADDR (:8443)
--tls-cert / ZDDC_TLS_CERT ("none" / empty / path)
--tls-key / ZDDC_TLS_KEY
--log-level / ZDDC_LOG_LEVEL (info)
--index-path / ZDDC_INDEX_PATH (.archive)
--email-header / ZDDC_EMAIL_HEADER (X-Auth-Request-Email)
--cors-origin / ZDDC_CORS_ORIGIN (https://zddc.varasys.io; "" disables)
--insecure-direct / ZDDC_INSECURE_DIRECT (false)
--help (prints flag list to stderr, exits 0)
--version (prints binary + embedded tool versions, exits 0)
So an operator can `cd /srv/zddc && zddc-server` with zero config — the
served root defaults to the current directory, and TLS defaults to a
self-signed cert. config.Load now takes []string (test-friendly: nil
skips flag parsing entirely; tests pass an empty slice for env-only
loads).
Adds a `version` package-level var in main.go injected at link time via
`-ldflags="-X main.version=..."`. The build.sh runs git describe against
zddc-server-v* tags; for in-flight commits between releases it produces
e.g. zddc-server-v0.0.7-19-gadb6904-dirty.
Adds an embedded versions manifest:
- Each tool's compute_build_label (in shared/build-lib.sh) writes a
sidecar <tool>.label to $BUILD_LABELS_DIR if that env var is set.
- Top-level build.sh sets BUILD_LABELS_DIR before running each tool's
build, then assembles zddc/internal/apps/embedded/versions.txt as
one `<app>=<build label>` line per app.
- apps.EmbeddedVersions() loads the manifest at runtime.
- main.go logs a compact summary on every startup; --version dumps
the full per-app label.
Removes the old cfg.BuildVersion field — the X-ZDDC-Source: embedded
header now uses the package-level main.version directly.

Updates every repo doc to reflect the simplified install model:
- Local install is just a download from /releases/.
- Server install is just running zddc-server (current-stable HTMLs
embedded at compile time).
- Customize via .zddc apps: cascade entries (channel/version/URL/path,
with default + per-app composition); editor at /.profile/zddc/.
Removes references to the old install scripts, level-1/level-2 stubs,
admin UI at /.profile/apps, SHA-256 verification, TOFU writes, refresh
worker, and ZDDC_APPS_* env vars.
zddc/README.md: replaces "Landing Page and Tool Install" section with
"Apps: virtual tool HTMLs" — covers the folder-name availability rules,
the resolution chain (real-file override / cascade / embedded), spec
syntax cheat sheet, cache layout under <ZDDC_ROOT>/_app/, the ?v=
cache-only override, and the X-ZDDC-Source response header.
ARCHITECTURE.md: install-distribution-model section rewritten to
describe the embed-first / cascade-override model with one canonical
example.
AGENTS.md, CLAUDE.md: short-form summaries pointing at the same model.
README.md: install bullet rewritten.

Extends the form-based .zddc editor at /.profile/zddc/edit?path=<dir>
with an Apps section between Admins and the Effective chain.
The section is a six-row table — default plus the five canonical apps —
with one text input per row. Each row's right column shows a server-
rendered "Resolves to" preview computed by walking the cascade through
this directory and applying default + per-app composition. The preview
displays the final URL, "embedded (build-time default)", or "local file:
<path>" so operators see exactly what will be served.
Help text covers the full spec syntax (channel/version/URL/path forms,
:channel shorthand, default key) plus the ?v= per-request override and
its cache-only security constraint.
Permission gating is unchanged: existing CanEditZddc() strict-ancestor
rule applies — subtree admins cannot edit the file that grants their
own authority. Field-level errors land inline next to the input, just
like the existing ACL/admins fields.
POST handler (internal/handler/zddchandler.go) accepts a new Apps map
in the JSON write request, validates via the existing zddc.ValidateFile
flow (which now enforces apps.<name> spec syntax), and writes
atomically through the unchanged zddc.WriteFile path.
Three new tests: round-trip apps including the default key, per-field
validation error returns, and editor renders the apps section with
existing .zddc values pre-filled.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.

The middleware chain in main.go was:
AccessLogMiddleware ( CORSMiddleware ( ACLMiddleware ( dispatch ) ) )
ACLMiddleware extracts the user email from the configured header and
stores it in the request context via r.WithContext. But Go's context
propagates DOWN the chain (to handlers further in) — not back UP. The
new context-bearing request only exists inside the call to
next.ServeHTTP; once that returns, the outer middleware still has the
ORIGINAL request without the email. So AccessLogMiddleware's
EmailFromContext(r) call (which runs after next.ServeHTTP returns to
log the request) read from the original context and got an empty
string, falling through to "anonymous".
The /.profile/ page worked correctly because it reads the email
directly inside the handler — at that depth the context-bearing
request is the one in scope.
Fix: invert the chain so ACL is OUTERMOST.
ACLMiddleware ( AccessLogMiddleware ( CORSMiddleware ( dispatch ) ) )
Now ACL extracts the email and the new request flows down through
AccessLog (which sees the email-bearing context), CORS, and dispatch.
Add three regression tests in middleware_test.go:
TestAccessLogReadsEmailFromACLContext
The fix: with ACL outer, AccessLog logs email=alice@example.com
when X-Auth-Request-Email is set.
TestAccessLogAnonymousWhenNoEmail
The unchanged path: no header → email=anonymous (correct fallback).
TestAccessLogOuterDoesNotSeeInnerContext
Locks down Go's actual context-propagation behavior. Builds the
INVERTED (buggy) chain and asserts that AccessLog (outer) does NOT
see the email ACL (inner) set. If this ever fails, Go's context
propagation has changed in a way that lets inner-set context flow
upward — which would mean the reordering fix could be reverted.
All zddc-server tests pass via `go test ./...` (run in podman against
golang:1.24-alpine since this dev host doesn't have Go installed).

Updates to all six top-level docs to describe the new flow:
- Storage: HTML tools live in website/releases/ as committed static
files. Per-version files are real bytes; partial-version pins and
channel mirrors are checked-in symlinks. No manifest.json, no Codeberg
indirection, no Caddy regex-rewrite.
- URL scheme: <tool>_v<X.Y.Z>.html (exact), <tool>_v<X.Y>.html (latest
patch), <tool>_v<X>.html (latest minor), <tool>_<channel>.html
(channel mirror). All resolve via the symlink chain.
- Cascade rule: stable cut → beta + alpha symlinks reset to stable;
beta cut → alpha resets to beta. Channels are never stale.
- No -alpha.N / -beta.N counter tags. Channel URLs are stable URLs by
design; counters defeat that. The on-page <date> · <sha> label is
enough for traceability.
- bootstrap/install.sh is the canonical install path. The four hand-
rolled snippets are gone; one script handles all three deployment
patterns + both target shapes.
- Helm charts under helm/ (zddc-server-{prod,dev}/) build from source
via init container; documented as the recommended k8s deployment
path.
- zddc-server now publishes binaries on stable cuts only — no alpha/
beta channel for binaries. Active dev runs through the dev helm chart
which builds from source on each rollout.
Files updated:
- CLAUDE.md — Repo shape, Most-used commands, Things that bite if you
forget. Drops mentions of manifest.json, the Codeberg-as-canonical
model, and -alpha.N/-beta.N tags.
- AGENTS.md — website/ tree, Releasing — channels and layout, Channel
discipline rules (renumbered to add coordinated minor/major bump
rule), Freshen helper, Bootstrap stubs, zddc-server Release tagging.
- ARCHITECTURE.md — website/ tree, build.sh step 5, Channels section,
level-2 bootstrap description.
- README.md — tool publishing description, link to helm/.
- bootstrap/README.md — install path is install.sh now; pin URL table
uses static symlinks; CORS check uses release-asset URLs (not
manifest.json).
- zddc/README.md — Quick Start uses Codeberg URLs directly (no proxy);
Release tagging is stable-only; Distribution / Versioning sections
rewritten.

Rolls back the HTML-tool side of the Codeberg-as-canonical refactor
(commits 2dc9ad2, b28c4ae, bdac8dc) in favor of a simpler model:
per-version HTML files committed under website/releases/ as immutable
real files; partial-version pins (<tool>_v<X.Y>.html, <tool>_v<X>.html)
and channel mirrors (<tool>_<channel>.html) are checked-in symlinks.
Docker-tag pattern: :1.2.3 is pinned, :1.2 floats, :1 floats further,
:stable floats furthest.
URL scheme — every URL resolves to actual HTML via the symlink chain;
no JS indirection, no manifest.json, no Caddy regex-rewrite:
/releases/<tool>_v<X.Y.Z>.html exact version (real file)
/releases/<tool>_v<X.Y>.html latest patch within X.Y.* (symlink)
/releases/<tool>_v<X>.html latest within X.*.* (symlink)
/releases/<tool>_stable.html current stable (symlink)
/releases/<tool>_beta.html current beta (symlink to stable when no
active beta; real file when beta is in flight)
/releases/<tool>_alpha.html current alpha (similar — symlink to beta
or stable when no active alpha)
Cascade rule (in shared/build-lib.sh promote_release):
--release [version] (stable cut) → write per-version file; refresh 5
symlinks (_v<X.Y>, _v<X>, _stable,
_beta, _alpha) → new versioned file;
tag <tool>-v<X.Y.Z>.
--release beta → overwrite <tool>_beta.html with real
bytes; cascade _alpha.html → _beta.html
(symlink). No tag — channel URLs are
stable URLs by design; counters defeat
that.
--release alpha → overwrite <tool>_alpha.html with real
bytes. No tag, no other side-effects.
Plain `sh tool/build.sh` → dist/ only. No website/releases/
side-effect, no commit.
Code changes:
- .gitignore — drop website/releases/*.html and website/releases/zddc-server-*
exclusions; HTML tool files are tracked again. Replace the comment with
the new model description.
- shared/build-lib.sh — drop next_prerelease (no -alpha.N / -beta.N counter
tags). Drop the Codeberg-upload path for HTML tools (no longer sourcing
publish-codeberg-release.sh from build-lib). promote_release rewritten
with two helpers: _promote_stable (per-version file + 5 symlinks + tag)
and _promote_channel (overwrite mirror + cascade alpha→beta on beta cut).
- zddc/release.sh — drop alpha/beta channel path entirely; binaries publish
only on stable cuts. zddc-server's beta/alpha builds-from-source via the
helm charts (next phase) — no binary distribution needed for those channels.
- bootstrap/level2.html.tmpl — drop manifest.json fetch; resolve ?v= to a
static URL via the symlink chain. New suffixFor() handles channel names,
exact versions, and partial-version pins (?v=0.0, ?v=0). Same logic in
level1.html.tmpl already works because the local-staging files (e.g.
../<tool>_v0.0.html) exist via the same symlink scheme.
- build.sh build_releases_index — revert to filesystem scan of
website/releases/ instead of Codeberg API call. Drop manifest.json
generation. Per-tool sections list channel chips + per-version pin links;
zddc-server section links to Codeberg release pages directly.
- tests/build-label.spec.js — fix the channel-label regex to match the
pre-release-semver format introduced in commit 9459139 ("v0.0.3-alpha · ...").
Pre-existing test failure that wasn't caught at the time.
Storage:
- 30 new committed files under website/releases/ — 10 real (per-version) +
20 symlinks (5 tools × 4 partial/channel variants, plus alpha as a real
file by default).
- Initial state: stable v0.0.2 across all 5 tools; alpha/beta/v0.0/v0
symlinks all point at <tool>_v0.0.2.html.
- manifest.json deleted (no longer needed).

The 2dc9ad2 commit ("refactor: distribute via Codeberg release assets,
drop the upstream image") rewrote AGENTS.md and CLAUDE.md but left
several pre-existing references to the old write-to-website/releases
flow and the now-removed Containerfile / podman-compose / release-image.sh.
This sweeps the rest:
- CLAUDE.md
- drop "podman/podman-compose" from the zddc/ blurb (no Containerfile)
- drop the broken `podman build -t zddc-server zddc/` command
- rewrite the "Most-used commands" table so --release semantics match
actual behavior (tag + Codeberg upload, not file write)
- rewrite "Things that bite": replace "never write to website/releases/"
and the obsolete "alpha exception" bullet with the new rules
($CODEBERG_TOKEN required, dist files no longer force-tracked, etc.)
- rewrite the website/ description in "Repo shape" to reflect that
only index.html + manifest.json live there now
- ARCHITECTURE.md
- rewrite the website/ directory tree (no more <tool>_v*.html, _stable
symlinks, or _alpha/_beta files)
- rewrite "Channels" section: every cut now tags + uploads to Codeberg,
alpha/beta have .N counters and matching tags, no more in-place
overwrites
- rewrite the build-label table: dev builds carry the next-stable
target as a -alpha pre-release suffix with full timestamp + dirty
marker (was: "Built: <ts> BETA")
- update level-2 bootstrap description: resolves channel via
manifest.json, fetches /releases/<tag>/<asset>, not a flat URL
- update landing-tool description: ships only as Codeberg release
asset, not a committed website/releases/landing_v<X>.html
- AGENTS.md
- update website/ tree to the post-refactor layout
- replace the two-step podman build / podman-compose run blocks under
zddc-server with a Go build + go run quickstart (no container in
this repo)
- drop the "Containerfile uses a multi-stage build" note from the
"Notes" list (Containerfile is gone)
- drop the stale "landing/build.sh writes website/index.html" note —
website/index.html is now hand-edited, not produced by landing's
build
- README.md (top-level)
- tools table no longer links to /releases/<tool>_stable.html
(those URLs return 404 post-refactor); link to the releases page
once instead
- bootstrap/README.md
- update the "permanent pin" URL examples and CORS verification
snippet to use /releases/<tag>/<asset> URLs (Caddy → Codeberg)
instead of the old flat /releases/<tool>_<channel>.html pattern
- explain that channel resolution is via manifest.json now
- zddc/README.md
- rewrite Quick Start: download a release binary or build from source,
no `podman build`
- rewrite TLS examples to invoke ./zddc-server directly instead of
`podman run ... zddc-server` (image name no longer exists)
- mention ZDDC_INSECURE_DIRECT in the env-var table and the plain-HTTP
example — startup is refused without it on non-loopback binds
- replace the "Container image" section with "Distribution" (binaries
on Codeberg, no image) and the "Building" section with go build
instructions
- replace "Release Tagging" with documentation of zddc/release.sh
(the canonical replacement for release-image.sh, which is gone)
- shared/build-lib.sh
- fix the comment claiming "plain builds mirror to website/releases/"
— they don't anymore

Removes the codeberg.org/varasys/zddc-server registry image, which had
no remaining consumer outside this shop. The two chart Dockerfiles
(tnd-zddc-chart) now compile zddc-server from source at build time,
fetching the right tag from a Codeberg release. release-image.sh,
zddc/Containerfile, and zddc/podman-compose.yaml are gone.
Build artifacts (HTML tools + zddc-server binaries) move from
website/releases/ in this repo to Codeberg release assets attached to
git tags. The website at zddc.varasys.io serves them by reverse-
proxying /releases/<tag>/<asset> to the corresponding Codeberg URL,
so consumers (zddc-use, level-2 bootstrap stubs, the chart
Dockerfiles) only ever talk to zddc.varasys.io.
Releases page becomes server-rendered static HTML regenerated on each
build via a single Codeberg API call. A small website/releases/manifest.json
maps <tool>-<channel> → tag for runtime channel resolution by zddc-use
and the level-2 stubs.
Files added:
- shared/publish-codeberg-release.sh — POSIX-sh helper that creates a
Codeberg release for a tag (sets prerelease flag from tag suffix)
and uploads/replaces release assets idempotently. Sourced by
build-lib.sh and zddc/release.sh.
- zddc/release.sh — replaces release-image.sh. Tags + cross-compiles
binaries via native Go (no podman needed; install Go) + uploads to
Codeberg release assets. No image build, no registry push.
Files modified:
- shared/build-lib.sh — promote_release tags + uploads via the helper
for stable AND alpha/beta now (alpha/beta were untagged before).
update_alpha removed; per-tool build.sh files no longer mirror to
website/releases/<tool>_alpha.html on plain dev builds.
- build.sh — prefers native go build over the old podman-based
cross-compile (which is gone with Containerfile). build_releases_index
queries the Codeberg API once and writes static HTML + manifest.json,
with graceful fallback when the API is unreachable.
- bootstrap/level2.html.tmpl — fetches manifest.json to resolve
channel → tag, then fetches the asset from /releases/<tag>/<asset>
(Caddy proxy). Replaces the old /releases/<tool>_<channel>.html flat
URL pattern. Operators with curl'd level-2 stubs need to re-issue
them — this is a breaking change.
- AGENTS.md, CLAUDE.md — rewritten to describe the new flow.
- .gitignore — releases/ artifacts now expected to be on Codeberg, not
committed locally.
NOT in this commit (deferred until $CODEBERG_TOKEN is provisioned):
- Backfilling existing tags as Codeberg releases.
- Cleanup commit: git rm-ing the existing artifacts in website/releases/.
Until backfill happens, those files are how operators with old
bootstrap stubs still get content. Once Codeberg has the assets,
drop them.
- The Caddy reverse-proxy config on zddc.varasys.io.
Operator-side changes (not in this repo):
- tnd-zddc-chart Dockerfile.prod and Dockerfile (dev) need updating
to compile from source rather than `FROM codeberg.org/...:stable`.
Done in a separate commit on that repo.
- Caddyfile rule for the /releases/<tag>/<asset> reverse-proxy.

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.

The "Install on your server" section of the home page now prints four
short shell snippets — copy-paste into a terminal, files land in CWD.
Each uses curl to fetch the relevant bootstrap files; nothing else to
install:
1. Self-contained: fetches the 5 current-stable tool HTMLs into CWD
plus a _template/ directory of level-1 stubs.
~1.8 MB on disk; no runtime dependency on the
site after install.
2. Track stable: fetches 5 tiny level-2 stubs (~10 KB total)
that fetch zddc.varasys.io's stable channel
on every page load.
3. Track beta: same, for beta.
4. Track alpha: same, for alpha.
Each snippet card explains when/why to use that option directly inline.
Implementation:
- build.sh now produces website/bootstrap/level1/<tool>.html and
website/bootstrap/track-{alpha,beta,stable}/<tool>.html as
standalone files (rather than packaging them into zips).
- install.zip and track-{alpha,beta,stable}.zip are removed; the
snippets curl the per-channel stubs directly.
- Docs updated: README, ARCHITECTURE, CLAUDE, AGENTS, bootstrap/README,
zddc/README, landing/build.sh comment.

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.

Adds tini to the runtime image and routes ENTRYPOINT through it so
zddc-server runs as PID 2 with proper orphan reaping and signal
forwarding. Today zddc-server is a single-process server and the change
is invisible; the motivation is the upcoming render path that will
shell out to pandoc (which itself shells out to xelatex / lua filters /
dot) — any grandchild orphaned by a mid-run crash gets reparented to
PID 1, and a Go server is not the right thing to put in charge of
reaping subprocesses it never spawned.
tini is ~24KB and does exactly this one job. Putting it in the upstream
image (rather than each downstream consumer's Dockerfile) means every
deployment of codeberg.org/varasys/zddc-server gets the fix for free,
including the Burns & McDonnell prod chart wrapper that's about to land.
Cut a new release with `sh release-image.sh <version> stable` to
publish.

The .archive virtual directory now emits both <tracking>.html (highest
base rev) and <tracking>_<rev>.html (each specific base rev) so HTML
documents can deep-link to a known revision and have it resolve to the
first chronologically received copy. Modifier files (<rev>+C1 etc.) stay
reachable via the resolver but aren't surfaced in the listing.
.archive at any folder depth serves the same global index — the depth
exists so offline HTML can use ../.archive/<tracking>.html and let the
browser resolve it before the request reaches the server. The earlier
attempt at scoping listings to the contextPath subtree was wrong; gating
is purely by ACL: contextPath gates the listing endpoint, and each
entry's resolved file gets its own per-target ACL check (404 on denial,
not 403, so cross-subtree existence isn't disclosed).
Adds the first tests for the previously untested archive package, plus
end-to-end ACL coverage for the handler (cascade direction, default-deny
once any .zddc exists, anonymous denied under allow:[\"*@…\"], stable
Location across contextPaths).

- release-image.sh now defaults to alpha (was stable). Active dev no
longer silently advances :stable; that tag only moves on a deliberate
`sh release-image.sh <ver> stable`. Same cascade logic, reordered
default. Updated AGENTS.md and zddc/README.md sections accordingly.
- zddc/Containerfile: dropped the "see .woodpecker.yml" comment since
that file no longer exists; pointed the docs to release-image.sh.
- build.sh: dropped the "CI builds the runtime container directly"
parenthetical; the cross-compiled host-binaries build is the only
thing that step actually produces.
Why alpha as the default: caught it during active development —
:stable kept advancing every release because the script defaulted
there. Solo workflow + alpha default = `:stable` is a deliberate
gesture, not a side-effect.

Removes .woodpecker.yml and replaces the tag-triggered image publish flow
with a local-build-and-push script (release-image.sh).
Why: the CI added two indirections (Woodpecker dashboard, Codeberg secrets
config) that aren't worth the cost for a single-developer release flow.
When the previous release didn't show up in the package registry, "did
the release happen?" required checking three places (the git tag, the
CI dashboard, the registry); with local builds, success or failure is
visible in the developer's terminal immediately.
The cascade behavior is preserved: `sh release-image.sh 0.0.3` publishes
:0.0.3 :stable :beta :alpha just like the .woodpecker.yml job did. Beta
and alpha channels work identically (`sh release-image.sh 0.0.3-beta.1
beta` → :0.0.3-beta.1 :beta :alpha).
The git-tag convention stays (`zddc-server-vX.Y.Z`); now you tag *and*
run the script as two coordinated steps. AGENTS.md "Release tagging" and
zddc/README.md "Release Tagging" / "Container image" updated to reflect
the new flow. No code change in the binary.

ACLMiddleware now slog.Debug's the configured email-header name, the
observed value at that name, and the full r.Header map on every request.
Off at the default INFO log level; enable per-pod with ZDDC_LOG_LEVEL=debug.
Motivated by debugging the X-Auth-Request-Email passthrough chain — when
access logs show email=anonymous, /.admin/whoami is unreachable (the
admin gate requires a non-empty email, which is the chicken-and-egg).
The debug log line dumps headers without the gate, so an operator can
identify whichever header name the upstream proxy is actually setting
(X-Forwarded-User, X-Forwarded-Email, Remote-User, X-Authentik-Email,
etc.) and adjust ZDDC_EMAIL_HEADER accordingly.
The debug-level dump captures auth tokens and cookies along with
everything else; safe in dev clusters, not appropriate for production
unless the operator is comfortable with the trade-off. README documents
the trade-off in the Admin Debug Page section.

Block style (one '- entry' per line) is recommended for hand-edited config
in this repo: cleaner diffs, easier to comment per-entry, no surprise YAML
quoting traps. The Admin Debug Page example mixed admins (block) with
acl.allow (flow); flip allow to block too for consistency.
Inline-in-table flow-style examples (lines 143-145) stay flow — block
style would mangle the cell layout — and that's a fine exception when the
list lives inside a one-cell context.

Listings now filter both '.' and '_' prefixes:
- '.' entries: excluded from listings AND 404 on direct HTTP access
(existing behavior). For invisible side-state like .devshell.
- '_' entries: excluded from listings only — direct URL access still
works. For operator scaffolding like install.zip's _template/
directory of bootstrap stubs that should be reachable but should
not appear in the project picker.
Filter applied at both listing entry points: ServeProjectList (the
project picker JSON at GET / Accept: application/json) and the generic
listing/FromDirEntries (used by ServeDirectory for sub-directory
browse listings).

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.

The renamed channel naming (latest → stable) only landed in the
filesystem layout and the bootstrap; the image-publish pipeline still
applied :latest as an alias for :stable on stable releases. Drop it
to avoid mixed terminology.
.woodpecker.yml: stable releases now apply only :X.Y.Z, :stable,
:beta, :alpha. zddc/README.md updated to show stable/beta/alpha
channel tags and explicitly note :latest is not published.
To clean up the existing :latest tag on the registry (one-time):
curl -X DELETE \
-H "Authorization: token $CODEBERG_TOKEN" \
https://codeberg.org/api/v1/packages/varasys/container/zddc-server/latest
or via the web UI at codeberg.org/VARASYS/-/packages/container/zddc-server.

The 'latest' label for the current-stable channel was inconsistent
with the channel set we use elsewhere (alpha / beta / stable). Rename
to 'stable' so URLs, file names, zip names, and image tags all line
up with the channel terminology used in the bootstrap, AGENTS.md
discipline rules, and chart consumers.
File / artifact renames
- website/releases/<tool>_latest.html → <tool>_stable.html (5 files)
- website/track-latest.zip → track-stable.zip
- shared/build-lib.sh: promote_release writes/refreshes _stable.html
- bootstrap/level{1,2}.html.tmpl: channels map drops 'latest', keeps
'stable' as the canonical name. ?v=stable is now the explicit way
to switch to current-stable for one request (alongside ?v=alpha,
?v=beta, and ?v=X.Y.Z).
- build.sh: install.zip sources from <tool>_stable.html; emits
track-stable.zip instead of track-latest.zip.
Container image (.woodpecker.yml rewritten)
- Tag publishing now cascades:
zddc-server-vX.Y.Z → :X.Y.Z, :stable, :beta, :alpha, :latest
zddc-server-vX.Y.Z-beta.N → :X.Y.Z-beta.N, :beta, :alpha
zddc-server-vX.Y.Z-alpha.N → :X.Y.Z-alpha.N, :alpha
- :stable, :beta, :alpha are now first-class channel pointers; chart
consumers (e.g. tnd-zddc-chart) can FROM :beta for dev and FROM
:stable for prod.
- :latest kept as an alias for :stable per Docker convention.
Documentation sweep
- AGENTS.md, ARCHITECTURE.md, CLAUDE.md, README.md
- bootstrap/README.md, zddc/README.md
- website/index.html, website/zddc-server.html
- transmittal/template.html, transmittal/README.md
all updated to reference _stable.html / track-stable.zip / the
'stable' channel name. ARCHITECTURE.md's manual freshen example
points at ./freshen-channel instead of the old git-checkout snippet.

Batch 1 of the chart-vs-project split. The project now ships a
hardened runtime image as part of every zddc-server release; downstream
deployments (e.g. the Burns & McDonnell Helm chart) will FROM this
image instead of cloning and building from source.
zddc/Containerfile (target: server)
- Tag the runtime stage `server` so `podman build --target server`
is unambiguous (the existing `binaries` target still works).
- Bake the bundled landing + archive tool HTML at /opt/zddc-server/web.
Useful for self-contained demos (`ZDDC_ROOT=/opt/zddc-server/web`)
and as a fallback web root when no external mount is supplied.
- Set fixed UID/GID 1000 for the non-root zddc user so volume
permissions are predictable across hosts.
- Add ENV ZDDC_ROOT=/srv default so a `podman run -v data:/srv` works
with no further config; explicit ZDDC_ROOT overrides.
- Declare VOLUME /srv to make the data-mount expectation explicit.
- Add OCI image labels (title, description, source, documentation,
license, vendor).
- Install ca-certificates so any future outbound HTTPS works.
- Add a HEALTHCHECK for `docker run` users (Kubernetes overrides).
build.sh
- Make the cross-platform podman binary build conditional on `podman`
being present. CI doesn't need it (the runtime container image's
own builder stage produces linux/amd64 internally), but having
build.sh sh-only-runnable means CI doesn't have to do nested
containers just to assemble dist/web.
- Reorder so `zddc/dist/web/` is assembled before the binary build
(allows the binary build to be skipped without breaking the bundle).
.woodpecker.yml (new)
- Triggers on tag push matching `zddc-server-v*`.
- Step 1 (alpine + sh): runs `sh build.sh` to assemble dist/web,
computes the image tag (`${TAG#zddc-server-v}` plus `latest`).
- Step 2 (docker-buildx plugin): builds and publishes
codeberg.org/varasys/zddc-server:{X.Y.Z, latest}. Auth via the
codeberg_user / codeberg_token Woodpecker secrets — these need
one-time setup in repo Settings; documented in zddc/README.md.
zddc/README.md
- New "Container image" section: pull URL, image properties (alpine,
non-root UID 1000, EXPOSE 8443, VOLUME /srv, baked web bundle),
example `podman run` invocation.
- New "Env-var contract (for chart consumers)" table: the variables
Helm charts and Compose files should set explicitly when running
behind a TLS-terminating reverse proxy with SSO. This is the
documented interface between project and downstream charts.
- "Release Tagging" section now points at .woodpecker.yml and lists
the two Woodpecker secrets that must be configured.
Validated locally:
podman build --target server -t zddc-server-test .
podman run -e ZDDC_ROOT=/opt/zddc-server/web -e ZDDC_TLS_CERT=none \
-e ZDDC_INSECURE_DIRECT=1 -e ZDDC_ADDR=:8080 \
-p 18080:8080 zddc-server-test
curl http://localhost:18080/ → HTTP 200, bundled landing tool.

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.
