Repoint default-tool/history/canonical-folder/auto-own/virtual/declared,
role-grant, and WORM-zone expectations to the top-level peer layout: archive
is now blanket-WORM (DC = rc there), the workspace/register peers carry the
DC grants directly, and incoming/working/staging/reviewing/mdl/rsk/ssr are
physical peers. ensure_test repointed to top-level paths + the virtual-reject
test inverted (peers are physical now).

Reshape the project layout from "archive/ is the only physical dir + six
virtual aggregators" to a flat set of physical, party-partitioned peers:
archive/<party>/{received,issued} pure WORM (one rule, no exceptions)
incoming|reviewing|working|staging/<party>/ workspaces
mdl|rsk/<party>/*.yaml registers (cross-party aggregate at the
peer root, $party from the real subdir)
ssr/<party>.yaml submittal status register AND the
authoritative party registry
A party exists iff ssr/<party>.yaml exists; the new `party_source: ssr`
cascade key gates party-folder creation under every other peer (archive
included) — create <peer>/<party> only when the registry row exists, else
409. Registration is a plain create of ssr/<party>.yaml (no WORM gymnastics),
so archive/ stays purely WORM.
Server core:
- defaults.zddc.yaml rewritten to the flat-peer + WORM-archive + party_source
shape; every virtual: removed; mdl/rsk get document_controller rwcd.
- slots.go: projectPeers/IsProjectPeer; perPartySlots={received,issued}.
- party_source key end-to-end (file.go/walker/lookups/cascade) + PartyRegistered.
- ensure.go canonical-ancestors generalized to peers; virtual reject removed.
- virtualviews.go: deleted the virtual-URL resolver/types/regex; kept
ListParties (reads ssr/*) + repointed ListRollupRows (physical <peer>/*/*).
- fs/tree.go: mdl/rsk peer-root listing aggregates physical party subdirs
(replaces the subdir folder-nav); ssr flat; spec entries advertised.
- fileapi.go: deleted virtual PUT/DELETE rewrites; mkdir allowlist → peers;
partySourceGate on mkdir/PUT/move.
- virtualviewhandler.go → ServeInjectedRow ($party/name injected on read so
the tables client renders the column unchanged).
- ssr/form/table handlers repointed to real paths (SSR create writes
ssr/<party>.yaml; rollup create writes mdl|rsk/<party>/<file>.yaml; SSR
rename is registry-only); IsDefaultSpec recognizes the new spec locations.
- accept-transmittal source incoming/<party>/<txn> (+ PartyRegistered guard);
plan-review scaffolds top-level reviewing/<party> + staging/<party>.
- main.go dispatch: removed virtual-row GET + folder-nav 302; injects the
source column on register-row reads.
Non-test build is green. Test suites still assert the OLD layout (verified:
all current failures are stale expectations, not bugs) — the test rewrite,
browse/tables client updates, and the data-migration script follow.

Consolidate edit-history bookkeeping under the single reserved .zddc.d/
sidecar (where tokens + access logs already live), instead of its own
top-level .history/ dot-name:
- history.go: record + text history now write/read <dir>/.zddc.d/history/<stem>/
(was <dir>/.history/<stem>/). Const renamed .history → .zddc.d/history and
unexported (the only external user was the dispatch carve-out). The history
VIEWER endpoints (<record>.yaml?history=1, <file>?history=…) read it
server-side, so they keep working for anyone with read on the live file;
the raw store is bookkeeping, blocked by the existing dot-prefix guard.
- main.go: drop the .history GET carve-out (b9ebee7) — superseded; history is
reached via the viewer, not raw browsing. Reword the guard comment to
"reserve .zddc.d/ bookkeeping" (Part B will replace the blanket block with a
.zddc.d/ admin-fence).
- Delete dead .devshell references (the dev-shell was dropped from the chart):
guard comment, paths.go comment, test fixtures/cases (→ .zddc.d), and docs.
This is Part A of the approved plan: ship history in its permanent home so we
never migrate it twice. Tests updated to the new paths; the obsolete
TestDispatchHistoryReadCarveOut is removed (raw-block covered by
TestDispatchHidesDotPrefixedSegments, viewer by mdhistory_test).

Two cleanups from the hard-coded-vs-cascade audit:
#2 Centralize the canonical slot names. The lists {ssr,mdl,rsk,working,
staging,reviewing} and the per-party {incoming,received,issued,mdl,rsk,
working,staging,reviewing} were hand-written across ensure.go (×2),
fileapi.go (×2), virtualviews.go, lookups.go. New internal/zddc/slots.go is
the single registry with IsRowSlot/IsFolderNavSlot/IsVirtualAggregatorSlot/
IsPerPartySlot; virtualViewRE is built from it. Slot NAMES stay hard-coded
(they carry bespoke behavior) but now live in one place — adding/adjusting a
slot is one edit, not a hunt. Pure refactor; behavior unchanged.
#1 Make the history file-type selection cascade-driven. IsTextHistoryCandidate
hard-coded ".md"; now it matches the effective history_globs from the .zddc
cascade (default ["*.md"], widen per-deployment e.g. ["*.md","*.txt"]). New
ZddcFile.HistoryGlobs + mergeOverlay + PolicyChain.EffectiveHistoryGlobs +
HistoryGlobsAt, threaded through serveFilePut/serveFileMove/dispatch and
ServeTextHistory (now takes fsRoot). The history: bool still gates whether
snapshots are recorded; history_globs only says which file types qualify.

Clicking a history snapshot in the tree 404'd: the dispatcher's dot-prefix
guard blocks every .-segment URL, and the preview fetch hit the raw
.history/<stem>/<snap>.md path. But .history is ACL-modeled content (it
inherits the shadowed file's .zddc chain), not infra like .devshell — so
the guard was redundant with permissions there.
Carve GET/HEAD of .history out of the dot-prefix guard: snapshots are now
fetchable as ordinary ACL-gated files (read the live file → read its
history). Writes into .history stay blocked, and the listing dot-filter
still hides it from default views unless ?hidden is set. Export
handler.HistoryDirName for the dispatcher.

Redesign the markdown edit-history store from content-hashed blobs +
log.jsonl to one self-describing file per save:
.history/<stem>/<ts>-<email>.<ext>
The filename IS the audit (colon-free UTC timestamp valid on SMB/Azure
Files + the authoring email); listing the directory is the history. No
sidecar log, no hashing. A byte-identical save is a no-op; a pre-existing
file lazy-seeds its current bytes (author "unknown", stamped at mtime).
Reverting copies an old snapshot back (records as a fresh save). Snapshots
are kept forever.
Fixes the 404 reading history: reads no longer require history to be
*currently* enabled — ServeTextHistory serves whatever .history/<stem>/
exists (empty list when none); the dispatch drops the EffectiveHistory
gate for reads. WRITES stay gated by the history: flag. (The 404 came from
the aggregator refactor turning history off on project-level working/,
which made already-recorded snapshots unreadable.)
Renames: an in-place rename carries .history/<stem>/ to the new name
(serveFileMove); a cross-dir move leaves it behind.
Defaults: history: true now ships on the three live-editing slots —
working, mdl, rsk — at both the project-level nodes and the per-party
folders. It's a .zddc cascade key, so operators override per project.
Records (.yaml in mdl/rsk) keep their separate record-history path.
Browse history viewer updated to the filename-based version id (id ←
sha). Tests rewritten for the per-file scheme + rename behavior + SMB-safe
names; HistoryAt defaults test updated.

enumerateAccess always computed the global summary — every project
(EnumerateProjects) and every admin subtree (enumerateAdminSubtrees tree
walk) — and merely appended the path-scoped fields when ?path= was given.
The browse hovercard calls this per folder hovered, so each distinct folder
paid a full global enumeration for data it never reads.
Split the two: a ?path= query now returns ONLY identity + path_verbs/
path_is_admin/path_can_elevate_grant/path_roles and skips the tree walks;
the no-path call still returns the full global view for the profile page.
Verified all path-scoped consumers (browse hovercard, form, tables) read
only path_* fields; the global consumers (elevation, stage, plan-review,
accept-transmittal) all call without ?path=.

Hovering a folder/file now shows "Your permissions" (the rwcda verbs you
hold there) and "Your roles" (the cascade roles you're a member of at that
location — e.g. document_controller, project_team). Roles are cascade-
scoped, so they can differ by location; this answers "does the system think
I'm a document_controller here?".
- server: RolesForPrincipalInChain(chain, email) resolves the caller's role
memberships at a path (honouring fences/resets, incl. embedded standard
roles); /.profile/access?path= now returns path_roles alongside path_verbs.
- browse hovercard: "Your permissions" from node.verbs (sync); "Your roles"
async-filled from /.profile/access?path= via zddc.cap.at (memoised).
Offline mode shows "local folder (filesystem)" and no roles row.
Tests: RolesForPrincipalInChain unit tests (member union, wildcard members,
non-member, fence-hides-ancestor-role, empty email).

Creating a folder/file at a project-level folder-nav aggregator root
(working/staging/reviewing) used to error or silently shadow — the slots
are virtual and content is party-scoped. Now browse opens a party picker
that targets archive/<party>/<slot>/<name>, with a "+ New party…" option
(server-gated to the document_controller via the existing archive/ ACL).
- events.js: aggregatorRoot detection + openPartyPicker modal (mirrors the
stage.js modal), createInAggregator routes the create to the canonical
archive path; rewriteAggregatorPath handles right-clicking a party row
shown in an aggregator listing so it never re-prompts.
- server: serveFileMkdir now 409s a mkdir inside an aggregator
(rejectProjectAggregatorMkdir) with a pointer at archive/<party>/<slot>/,
instead of letting the write fall through to an unreachable shadow dir.
Reverts the prior session's project-level creator-owned working/ folders
(per the design decision to make all three folder-nav slots uniformly
party-scoped): working/ is a pure virtual aggregator again like
staging/reviewing — drops the working/ history+auto_own+acl defaults, the
EnsureCanonicalAncestors working exception, the working-root document-
controller file gate (serveFilePut/Move) and zddc.IsRoleMemberAt. Per-party
archive/<party>/working/ keeps its own history + auto-own.

Replace the project-level working/<email> "personal workspace" idea (too much
complexity for too little) with a simpler model on the virtual <project>/working/:
- EnsureCanonicalAncestors now materialises the working/ slot dir on disk the
first time real content is created beneath it (it stays a plain dir, never
auto-owned). ssr/mdl/rsk/staging/reviewing keep rejecting physical writes.
- Each <project>/working/<folder>/ a user creates gets an unfenced auto-own
.zddc (creator rwcda; the team inherits read+create-new, not w/d). history:
true still inherits in, so markdown drafts there are versioned.
- defaults grant project_team rc + document_controller rwc at working/ so users
can create their folders and the DC has authority throughout.
- A bare file DIRECTLY at the working/ root is reserved for the
document_controller: serveFilePut and serveFileMove reject non-DC writes/moves
there (isProjectWorkingRootFile + zddc.IsRoleMemberAt), independent of the ACL
verb since mkdir and file-PUT both authorise as ActionCreate. Users work inside
a folder; the DC creates files at the root or promotes one up with a MOVE.
Tests: ensure_test materialisation + plain-slot cases; fileapi_test DC-gate for
PUT and MOVE. The generic dispatch-routing test moves its ops into working/drafts/.

Per the working-folder design: <project>/working/<email>/ is each user's
personal workspace (public by default, owned by the creator who can privatize
via .zddc). The post-reshape defaults had stripped that node to a bare
aggregator, so personal markdown drafts got no history. Add history: true +
an auto_own (un-fenced) per-user-home rule to the project-level working node.
archive/<party>/working/ keeps its own history: true. Scope stays working-only
(staging/reviewing unchanged).

mergeOverlay (used to thread embedded defaults' paths: tree into chain
levels) didn't copy the new History *bool, so EffectiveHistory never saw
history: true on archive/<party>/working/ — the feature would have silently
never triggered. Add the field to the overlay and a HistoryAt defaults test
that exercises the real cascade (working/ + fenced homes true; sibling slots
false).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
A history: true .zddc subtree (enabled by default on archive/<party>/working/)
routes markdown PUTs through WriteTextWithHistory: each save snapshots the
content into a hidden, immutable .history/<stem>/ store (content-addressed
blobs + an append-only log.jsonl carrying server-stamped {ts, email, sha,
prev}) before writing the live file. The live file at its natural path stays
the source of truth; no symlinks, no audit in the body/filename.
Reads: GET <file>?history=1 lists versions (newest-first, current flagged);
GET <file>?history=<sha> returns that version's bytes (hex-id guard against
traversal). Listings carry a per-file History flag so the browse client knows
where to offer the affordance.
History is subtree-inheriting and ignores inherit:false ACL fences (versioning
is a write behavior, not a permission), so fenced per-user homes under working/
are covered too. No-op saves dedup; pre-existing files lazy-seed their origin
version. Records (.yaml) keep their existing in-body-audit history path.

TestInvariant_ProfileAdminEndpointsHideFromNonAdmins was skipped pending the
ServeProfile dispatcher refactor — which has since landed (ServeProfile in
profilehandler.go is the entry point, with an adminOnly wrapper that denies
with 404). Implement the test against it: non-admin, anonymous, and
un-elevated-admin callers must get 404 (never 403/200) on every admin-gated
sub-resource (/whoami, /config, /logs, /effective-policy, /reindex), so the
namespace can't be enumerated; an elevated admin gets through (/whoami,
/config positive control). Locks in the existence-hiding security property
that was previously unverified.

indexTransmittalFolder silently dropped per-entry walk errors (`_ = err`),
so a permission or filesystem error on one file vanished without a trace —

Root cause of the flaky cache tests (TestServeHTTP_DirectoryListingsCachedAsSidecar
and the other hit-path tests, ~1-in-many under parallel load): on a cache
hit, ServeHTTP launches `go c.revalidate(...)` / `go c.revalidateListing(...)`,
which write into the cache root (MkdirAll + CreateTemp + Rename). Those
goroutines outlive the request — and in tests, the test — so they race
t.TempDir's RemoveAll cleanup, recreating the dir or dropping a temp file
mid-removal. testing then reports "TempDir RemoveAll cleanup: ... directory
not empty" and marks the test failed (with a 0.00s body, no assertion line).
It only surfaced under the full parallel suite / -count because the timing
has to collide.
Fix: track these background goroutines in a sync.WaitGroup via a goBackground
helper, and expose Wait(). newTestCache registers t.Cleanup(c.Wait) — cleanups
fire LIFO and t.TempDir registered its RemoveAll first, so the drain runs
before it (upstream Close was registered earliest, so it runs last and stays
up while goroutines finish). runClient also calls cacheLayer.Wait() after
srv.Shutdown so in-flight sidecar writes complete on graceful shutdown rather
than being abandoned.
Verified: cache package at -count=200 reliably failed before, passes clean
after (0 failures, 0 cleanup errors); full `go test ./...` + vet green.

The project-rollup forms derive originator from the selected Package
(party folder) server-side, so the field is read-only and was blank
until submit. Add a declarative `ui:mirrorFrom: <sibling>` hint: the
object renderer wires the named sibling's input to the field so the
read-only originator updates live as the user picks a party — the
composing tracking number is visible while filling the form. Display
only; the server stays authoritative via the cascade's folder_fields.
Set `ui:mirrorFrom: party` on originator in the embedded
default-project-{mdl,rsk}.form.yaml. Generic hint, not hardcoded field
names, so operators can reuse it.
Test: form-safety.spec.js — filling the source field updates the
read-only target; the target is not editable.

- Add RecordRule.UnmarshalYAML so a misconfigured folder_fields fails
when the .zddc is parsed, not as a 500 on the first record write. A
negative parent-distance is now rejected with a message naming the
field. Mirrors FieldCode.UnmarshalYAML's raw-alias pattern.
- Memoize anchored field-code pattern regexes in a package-level
sync.Map (compileFieldPattern), used by both the unmarshal-time
validation and FieldCode.Validate — replacing the per-call
regexp.Compile that the old comment flagged as cache-if-it-shows-up.
Tests: negative distance rejected (standalone + nested in a records:
map), valid distance round-trips, pattern field code matches anchored.

The in-dir form create/update (serveFormCreate/serveFormUpdate) wrote
records with plain WriteAtomic + date+email naming — no audit stamping,
no filename composition, no field_codes/folder_fields. So "+ Add row"
from a per-party mdl/rsk table produced un-stamped, mis-named rows that
the tables tool's own PUT-update path (which composes) would then 422
on. Only PUT and the project rollup honored the record machinery.
Now every record-write entry point converges on WriteWithHistory:
- Extract the shared field_defaults + folder_fields + row-assign +
compose step into recordCreatePrep (history.go); the rollup uses it
too, replacing its inline copy.
- serveFormCreate: when a records: rule with a filename_format applies
in the target dir, compose the name + route through WriteWithHistory;
otherwise keep the generic date+email submission write.
- serveFormUpdate: route through WriteWithHistory unconditionally — it
stamps/historizes records and plain-writes non-records. Editing a
tracking-number component in place now 422s (identity is the
filename; renames are delete+create).
- Drop originator from required: in the per-party mdl/rsk forms and mark
it readOnly, matching the rollup forms — it's server-derived from the
party folder, so a create needn't send it.
Docs (AGENTS.md, ARCHITECTURE.md) updated for the converged wire
surface. Tests: in-dir record create composes + stamps audit +
folder-binds originator; in-dir update bumps revision and rejects an
in-place component edit.

Two coupled cleanups so the baked-in defaults reflect the actual
convention instead of leaking one project's choices into every
deployment:
- Drop the project-wide phase/area components from the default
filename_format, form schemas, and table columns. They must be
all-on or all-off across a project to keep filenames lexically
consistent, so the simplest default omits them; operators re-enable
via the commented-out templates + a .zddc filename_format override.
Teaching comments (incl. a field_codes: example) now ride along in
defaults.zddc.yaml, which `show-defaults` dumps verbatim.
- Separate suffix from sequence with a template hyphen
({sequence}-{suffix?}); stored suffix is now just the part marker
(A, 01) with no leading dash.
- New records: key `folder_fields: {field: parent-distance}` binds a
body field to an ancestor folder name. The default mdl/rsk records
bind originator to the party folder (distance 1) — the folder is the
sole source of truth. The server overwrites the body value before
validation + composition (WriteWithHistory and the rollup create
path), and the form renderer marks the field read-only and pre-fills
it. Rollup forms drop originator from required (server derives it
from the selected party).
Tests: folder-binding overwrite + wrong-originator-filename 422, and a
form-render readOnly/prefill assertion; existing record tests realigned
so the party folder name equals the originator.

The synthetic spec entries injected into rollup virtual surfaces
(/<project>/{ssr,mdl,rsk}/) had Verbs hardcoded to "r" — so even
an elevated root admin saw the spec files as read-only in the
YAML editor's verbs check (cap.has(node, 'a') returned false →
saveBtn disabled + the red read-only banner).
The hardcode was a Part 2 oversight; every other synthetic listing
entry already computes verbs via EffectiveVerbsFromChainP against
the entry's path. Now table.yaml and form.yaml do the same — elevated
admins get "rwcda" and can PUT a custom spec to override the embedded
default at the rollup view; everyone else still gets "r" via the
project-level project_team:r grant cascading through.

Four root causes, each affecting one or more pre-existing
failures. All resolved without weakening any assertion.
1. build-label.spec.js (×4 — archive/transmittal/classifier/browse)
The regex accepted v<X.Y.Z>-alpha|beta channel labels but not the
-dev label modern dev builds emit. CLAUDE.md describes
v<X.Y.Z>-dev as the canonical dev-build form. Added |dev to the
channel alternation; tests now pass on dev builds and remain
tight on stable cuts.
2. landing.spec.js (×8)
SAMPLE_PROJECTS fixture pre-dated the post-reshape listing JSON
contract. The landing's loader now filters projects on
`is_dir: true`; the fixture didn't set it, so every entry was
filtered out and every "renders a project table" test failed at
the `.project-table` wait. Added `is_dir: true` (and trailing
slash on names, matching the live server's shape) to the three
fixture entries.
3. browse.spec.js (×1 — Download (zip))
The #downloadZipBtn toolbar button was retired in the SPA
overhaul (94b2e29) — Download ZIP moved to the right-click
context menu. Test still poked the dead toolbar button. The
picked-root folder no longer renders as a row (only its
contents do), so the test now scopes the assertion to
downloading a sub-folder (sub/) via right-click → Download ZIP;
verifies the zip's entries, magic bytes, and filename.
4. tables.spec.js (×1 — Phase 3 row-blur fires PUT)
Real bug, not a test issue. The editor's commit path tears down
its input element (clearing focus to body) before refocusing
the owning cell. main.js's focusout-on-#table-root handler ran
synchronously, saw `relatedTarget=null`, treated it as "user
left the grid", and fired flushAll() — racing the
selection-change save that fires from the subsequent
setSelected(r+1, c) inside the Enter handler. Net effect: two
identical PUTs per row-blur. Deferred the focusout check to
next tick via setTimeout(0); the cell.focus() inside the
editor's tearDown has time to settle, and the deferred check
sees document.activeElement still inside #table-root → skips
the redundant flush.

DCs are typically internal employees and ARE in project_team (when
project_team is the realistic *@example.com wildcard). The cascade's
"deepest level that has any matching principal wins" semantic means
a project_team:cr grant at the slot level would shadow the DC's
party-level rwcda — leaving DCs limited to project_team's grant.
Fix: at every slot with a project_team-specific grant, restate
document_controller's role grant. The within-level union of all
matched principals then gives the DC rwcda ∪ cr = rwcda. No cascade
semantics change; just verbose defaults.
working/ project_team: cr, document_controller: rwcda (new DC line)
staging/ project_team: cr, document_controller: rwcda (upgraded from rwcd —
adds `a` for
Plan Review's
staging/<tracking>/.zddc)
reviewing/ project_team: cr, document_controller: rwcda (new DC line)
Test fixture flipped from disjoint-role members to the realistic
project_team: ["*@example.com"]; verifies DC's rwcda survives the
wildcard via within-level union at each slot.
Docs updated:
- AGENTS.md "Standard roles": describes the role-restate pattern
+ flags the internal-observer-via-wildcard caveat (operators
needing internal observers should avoid the *@ wildcard for
project_team).
- ARCHITECTURE.md "Standard roles": same model description; drops
the now-incorrect "subtree-admin of every archive/<party>/"
line, replaces with the auto_own_roles role grant.
- planreview_test.go fixture comment: reflects that the test
uses root-admin to bypass ACLs, with non-root-admin DC path
covered by standardroles tests' auto-own .zddc simulation.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two related schema/defaults changes that together replace the
admins:[document_controller] subtree-admin status with a cleaner
role-grant-via-auto-own model, and lock down the one-way handoff
through the in-flight lifecycle slots.
## New: auto_own_roles
ZddcFile.AutoOwnRoles []string is a new field on the parent's .zddc
declaring "when this directory's auto_own fires, also grant these
roles rwcda alongside the creator email". The writer
(WriteAutoOwnZddc + WriteAutoOwnZddcFenced) now takes a roles slice
and writes both the creator email AND each named role as rwcda in
the new .zddc. mergeOverlay treats AutoOwnRoles like other path-tree
contributions (leaf-wins).
The defaults' archive/<party>/ entry now sets
`auto_own_roles: [document_controller]` and drops the
`admins: [document_controller]` line:
- When any DC mkdir's archive/<party>/, the auto-own .zddc grants
both their email and the role rwcda. Peer DCs share full
authority at every party without any DC needing subtree-admin
status.
- DCs are no longer subtree-admins anywhere. They can't bypass
WORM (only worm-create via the worm: list) and can't reach
inside fenced working homes. Admin elevation is reserved for
the root admins: list.
- Plan Review's ActionAdmin pre-flight passes for any DC via the
role grant cascading into reviewing/ and staging/.
## In-flight ratchet (working → staging → issued)
Per-role grants at the lifecycle slots formalise a one-way handoff:
working/ project_team: cr (create their own folders;
auto_own_fenced gives rwcda inside)
staging/ project_team: cr (drop files, no modify after — the
"commit" step; DC takes over)
document_controller: rwcd (transfer-to-issued needs `d`)
reviewing/ project_team: cr (create iteration folders; auto_own
unfenced grants rwcda inside)
received/ worm cr (file write-once)
issued/ worm cr
Each handoff drops the previous role's modify rights for the slot
they pushed from. Comments in defaults.zddc.yaml document the
pattern + the "project_team drops files at staging root, never
mkdirs" convention.
## Tests
TestStandardRoles_DocControllerScopedCreate rewritten — flips
from IsSubtreeAdmin assertions to verifying:
- rwcda at <party>/ via the auto-own .zddc (creator + role)
- rwcda cascading to working/reviewing/ (no slot override)
- rwcd at incoming/staging/ via explicit grants
- cr at received/issued via WORM mask
- IsSubtreeAdmin = false everywhere
- DC blocked from alice's fenced working/<email>/ home
New TestStandardRoles_DocControllerMultiDC — a second DC in the
role gets the same rwcda at any party a peer created, via the role
grant in auto_own_roles.
New TestStandardRoles_ProjectTeamInFlightRatchet locks the ratchet:
project_team gets cr at working/staging/reviewing, r at incoming/
received/issued.
New TestStandardRoles_DocControllerStagingDelete confirms DC has
`d` at staging/ for the transfer-to-issued workflow.

Add GET /<path>/.zddc?effective=1 returning JSON with the composed
ZddcFile across the full cascade plus a per-level source list. The
.zddc file itself still serves only what's defined at that level
(YAML, the source of truth); the new query is inspection-only
(JSON, never written back). The virtual .zddc body's header
comment already pointed at this URL — now it's live.
Wire shape:
{ url_path: "/Project-1/archive/Acme/working/",
merged: { …ZddcFile JSON, composed view… },
sources: [ { level: -1, url: "<embedded>",
contributed: ["roles", "available_tools", "paths"] },
{ level: 0, url: "/.zddc",
contributed: ["acl", "admins"] },
{ level: 4, url: "/Project-1/archive/Acme/working/.zddc",
contributed: ["default_tool", "auto_own", …] } ] }
New zddc.EffectiveZddc(chain) walks chain.Embedded then
chain.Levels[VisibleStart..leaf] through mergeOverlay, and folds the
cross-level Roles union (via the existing lookupRoleMembers,
matching the runtime ACL evaluator's semantics). Returns
([]SourceEntry) listing each contributing level with its non-zero
top-level fields. The handler maps SourceEntry.Level to a directory
URL: -1 → "<embedded>"; 0..n → "/<seg/seg/.../>.zddc".
ACL gate is the same as the YAML view (read on the directory).
X-ZDDC-Source: virtual:effective so clients can distinguish.
Four tests cover the contract:
- BasicCompose: alice's root grant + project_team baseline from
embedded + the project's title all surface in merged; sources
include -1 (embedded), 0 (root), 1 (project).
- InheritFence: top-level inherit:false on /Closed/.zddc drops
every ancestor including the embedded baseline from sources.
- RoleMemberUnion: document_controller declared at root and
project unions members in merged.roles (matches the runtime
cross-level union the ACL evaluator performs).
- existing virtual-body tests still pass — they hit the YAML path,
not the JSON branch.

When no .zddc is on disk at the requested directory, ServeZddcFile
now renders the cascade's leaf-level ZddcFile as YAML — what
defaults.zddc.yaml's paths: tree declares for THIS exact path,
threaded through by the walker. The previous body was a comment-
only summary plus a `{}` placeholder, which forced operators to
write any override from scratch.
The .zddc file is still the single source of truth — no synthesis,
no merge: the virtual body IS the embedded subtree, marshalled in
the same shape the operator would write themselves. PUT-saving the
bytes back through the file API materialises an on-disk override
carrying exactly what the user saved. For the COMPOSED view across
the full chain, slice 2 will add ?effective=1 (returns JSON, not a
.zddc); the header comment in the virtual body points at it.
Three new test cases lock the contract:
- VirtualDefault: at /Project/.zddc with no on-disk file, the
embedded paths.* contribution surfaces (project_team: r,
observer: r, archive subtree, …).
- VirtualEmpty: at a path the embedded defaults don't declare
(e.g. /Project/random-subfolder/.zddc), the body collapses to
the header + an empty-document {} placeholder + an explanation
that rules come from ancestors only.
- VirtualPerPartyWorking: at /Project/archive/Acme/working/.zddc,
the body carries default_tool/auto_own/drop_target and the
classifier in available_tools — the per-party in-flight slot's
full declaration.
Drive-by: add `omitempty` to ZddcFile.ACL, .Admins, .Title yaml
tags. Without it, the marshaled virtual body carried `acl: {}`,
`admins: []`, and `title: ""` at every nested level, drowning the
real content in noise. ParseFile is unaffected (input parsing
ignores omitempty); WriteFile's round-trip sanity check still
passes.

ACL-deny sites now write a JSON body naming the missing verb so the
client-side toast can render "you need <verb> here" and offer
elevation (the path-scoped /.profile/access?path= reports whether
elevation would unlock the verb).
Body shape:
{"error": "Forbidden", "missing_verb": "w"}
New helper writeForbidden(w, action) in errors.go, applied at the
four primary ACL-deny gates:
- directory.go (list, action=read)
- fileapi.go (file CRUD; action varies per request)
- tablehandler.go (table read)
- archivehandler.go (existence-leak guard, treated as read)
Other 403 sites (no authenticated principal, planreview detail
errors) keep their plain-text bodies — "missing_verb" doesn't apply
there. Existing clients that read the body as text see the JSON
string instead of "Forbidden\n"; no client in this repo parses the
body for content, so it's a non-breaking change in practice.

Existing /.profile/access stays unchanged when called without ?path=;
the path-scoped fields are populated only when the caller passes a
URL path, so each tool can fetch its root capabilities in one round
trip and gate top-of-page affordances (transmittal Publish, tables
+Add row, browse +New folder) accordingly.
Three new fields (all omitempty so the global shape doesn't change):
- path_verbs: rwcda subset granted at the requested path under the
caller's CURRENT elevation state.
- path_is_admin: subtree-admin authority at the requested path,
again under current elevation. Distinct from "verbs include 'a'":
admin authority is WORM-bypass capability, not just .zddc edits.
- path_can_elevate_grant: verb set the caller would hold AT THIS
PATH if they elevated — empty when elevation wouldn't change
anything (already elevated, or no admin grant on chain). Drives
toast offers like "Elevate to delete this file".
Path resolution mirrors serveProfileEffectivePolicy: must start with
"/", must not escape ZDDC_ROOT. Validation failures leave the fields
empty rather than 400ing — the global view is still useful, and the
client can detect absence.

Add a `verbs` field (canonical "rwcda" subset) to every directory
listing entry, computed via a new
`policy.EffectiveVerbsFromChainP(ctx, d, chain, p, path)` helper that
routes each of the five actions through the decider and unions the
allowed bits — so an external OPA's overrides surface in the wire
field, and active-admin elevation produces the full grant.
Semantics:
- file entry: verbs from the parent dir's chain (files inherit;
they have no .zddc of their own). Same chain Writable uses.
- directory entry: verbs from the subdir's OWN chain, so a fenced
or extended .zddc inside it shows through.
- virtual entries (auto-own homes, canonical-folder placeholders,
workflow received/ window, table.yaml/form.yaml spec rows):
verbs computed against the would-be path's chain so client
affordances render correctly before any write materialises a
real folder.
Writable stays in lockstep with verbs for the transition window so
existing clients (markdown/yaml editor save buttons) keep working
unchanged. Clients should migrate to checking 'w' in verbs and let
Writable wither.

A third standard role for auditors, regulators, and external
read-only viewers. Like project_team it gets project-wide `r`, but
unlike project_team the role itself carries no `c` anywhere — so an
observer can't bring a working/<email>/ home into existence under
auto-own, even though the auto-own mechanism is path-keyed rather
than role-keyed.
Approver-by-design: the role audit explicitly rejects a separate
`approver` role. Plan-Review approval stays with document_controller;
two-person sign-off, when needed, is expressed via per-folder `.zddc`
overrides rather than baked-in roles. Comments in defaults.zddc.yaml
and ARCHITECTURE.md call this out so future role audits don't
reopen the question.
TestStandardRoles_ObserverReadOnlyEverywhere locks the invariants:
project-wide r, no c at archive/incoming/working/staging/reviewing,
WORM zones read-only (no worm-create), and not subtree-admin
anywhere even when notionally elevated.

May 2026 reshape. archive/ is now the only physical project-root
directory; working/, staging/, reviewing/ move from the project root
into each archive/<party>/ folder. Six top-level URLs become virtual
aggregators served via the cascade rather than disk:
ssr/mdl/rsk tables rollups across parties with a
synthesised $party source-party column
working/staging/ browse folder-nav listings of parties with
reviewing non-empty content in the slot; per-party
URLs 302-redirect to archive/<party>/<slot>/
Mkdir at the project root is restricted to `archive` and `_`/`.`-
prefixed system names — virtual aggregator names and ad-hoc folders
return 409.
Plan Review hardcodes the scaffold convention (archive/<party>/
{reviewing,staging}/<tracking>/); the pre-reshape
on_plan_review.{reviewing_root,staging_root} cascade keys are dropped.
document_controller is now subtree-admin of every archive/<party>/
(not of project-root working/staging/ as before), so per-party
lifecycle slots inherit admin authority through the cascade.

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

A fresh ZDDC deployment grants no access to anyone until an operator
populates the root .zddc (admins) and per-project .zddc files (role
members). Until now this was only documented in comments inside the
embedded defaults.zddc.yaml, surfaced via `zddc-server show-defaults`
— operators wiring up a fresh master had no obvious doc to follow and
no startup signal when the bootstrap was missing or empty.
- README.md: new "## Deploy: bootstrap config" section between Tools
and File-naming convention. Two canonical examples (root admin-only,
per-project role members), schema essentials (verb bits, principal
forms, admins-only-at-root), and the acl: { allow: [...] } footgun
that silently drops grants.
- AGENTS.md: new "### Bootstrap config (REQUIRED — unlocks the server)"
subsection at the top of ## zddc-server. Same content as README but
with file:line citations into zddc/internal/zddc/file.go for the
schema source of truth.
- zddc-server: new warnIfNoBootstrap fires a slog.Warn at startup when
the root .zddc grants nobody anything (no admins, no acl.permissions,
no role members). Master mode only; skipped under --no-auth.
- config validator's existing no-root-.zddc fail-fast error message now
also points at the new README + AGENTS sections so all three signals
(fail-fast, runtime warning, docs) converge.
Smoke-tested all paths: empty root + default (fail-fast), empty root +
--insecure (file-missing warn), admins-only / perms-only / role-members
-only (silent), title-only and acl.allow footgun (both warn), --no-auth
(suppressed). All existing go tests pass.
Follow-up (manual, separate repo): add an analogous section to
~/src/zddc-website/reference.html.

Adds history_test.go with eight cases exercising the record-write
orchestration path:
- CreateStampsAuditFields: PUT to a fresh mdl path → audit fields
injected; response echoes the stamped YAML; no history dir yet.
- UpdateIncrementsRevisionAndArchivesPrior: second PUT archives
the prior bytes under .history/<base>/<ts>-<sha8>.yaml, bumps
revision, preserves created_*, chains previous_sha.
- ConflictPreservesHistory: 412 from stale If-Match leaves the live
file untouched and writes NO history entry (the failed write must
be a true no-op).
- ClientAuditFieldsStripped: client-supplied created_by / revision
are silently overwritten by server values — anti-forgery test.
- FilenameMismatch: URL says ...-0002 but body composes to ...-0001
→ 422.
- LockedFieldRejected: posting type=SPC to an rsk row → 422 with
/type error (rsk/ locks type=RSK via cascade).
- SSRHistoryAtPartyLevel: writes to archive/<party>/ssr.yaml put
history at archive/<party>/.history/ssr/, NOT at
archive/.history/<party>/.
- RollupCreate_AssignsRowAndComposesFilename: three POSTs to
/project/rsk/form.html in two table-scope groups demonstrate the
server picks up filename_format + row_field+row_scope_fields from
the cascade, auto-assigns sequence row numbers per group, and
composes the canonical filename.
Bug fix surfaced by the first test: composeFilename was eliding TWO
separators around an optional placeholder when one was correct.
"ACM-{phase?}-PRJ" with phase="" was producing "ACMPRJ" instead of
"ACM-PRJ". Now drops only the trailing separator from output and
lets the next iteration emit the connector.
Default-project-{mdl,rsk}.form.yaml updated: project-rollup MDL +
RSK schemas gained the six readOnly audit fields and the project-
rsk schema picked up the full table-tracking component shape (+
row) plus an enum-locked type=RSK. The required: list no longer
includes type for rsk schemas — the cascade's field_defaults
injects it after schema validation, and requiring it would 422
well-behaved clients.

Two extension fields added to jsonschema.Schema so server-injected
constraints survive the YAML→Schema→JSON round-trip:
- Pattern: regex hint for the form renderer (server-side validation
for field_codes already runs via WriteWithHistory).
- ReadOnly: surfaces locked / audit fields as disabled in the UI.
- Labels: x-labels extension carrying human-readable display strings
paired with enum keys (e.g. ACM → "Acme Inc"), so dropdowns can show
"ACM — Acme Inc" rather than bare codes.
serveFormRender now calls augmentSchemaFromCascade after loading the
spec: per-field, it injects enum (from field_codes:codes), pattern
(from field_codes:pattern), readOnly (from records:locked), and
default (from records:field_defaults). The augmentation is
per-request and never touches the on-disk *.form.yaml — operators
who declare their own enum/pattern in the spec take precedence
(injection is "if absent").
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Schemas:
- default-mdl.form.yaml: declare the six readOnly audit fields
(created_at/by, updated_at/by, revision, previous_sha) so the form
UI renders them disabled. additionalProperties: false is preserved;
WriteWithHistory strips any client-supplied values before validation.
- default-rsk.form.yaml: overhaul to reflect the new shape. Each row
now carries the table-tracking components (originator/phase?/project/
area?/discipline/type/sequence/suffix?) plus a server-assigned `row`
field; type is enum-locked to RSK to mirror the cascade's locked: rule.
Drops the old `id` field (D-001/R-001-style identifiers are now
composed from the components and stored in the filename).
- default-ssr.form.yaml: append the six audit fields.
Handlers:
- serveFormCreateSSR routes the write through WriteWithHistory so
audit fields are stamped on first create (revision=1, created_*=
updated_*=request principal/now). ssr.yaml's identity stays the
party folder name; no filename composition runs.
- serveFormCreateRollup now resolves the cascade at the row's parent
folder and uses the matched records: entry's filename_format to
compose the row filename from body fields. For RSK rows the rule
carries row_field+row_scope_fields, so the server auto-assigns the
next sequence (001, 002, ...) within the table-tracking group and
injects it into the body before composition. Defaults from
field_defaults: are injected where the client omitted them
(type=RSK locks in via the locked: list). Falls back to the
historical date+email naming only when no records: rule is in
scope (covers deployments that override defaults.zddc.yaml without
declaring their own records: entries).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds cascade-driven schema + immutable audit history for the three table-style
record stores (mdl, rsk, ssr). Two new .zddc top-level keys carry the rules:
- field_codes: discriminated-union vocabulary (kind: enum|pattern|free) for
the components used to compose tracking-number filenames and constrain
record bodies. Map-merge across the cascade, mirror of apps: semantics.
- records: per-pattern rules (filename_format, field_defaults, locked,
row_field, row_scope_fields). Filename-pattern scoping lets the SSR rule
live at the party-folder level without bleeding onto mdl/rsk siblings.
PUTs to record YAML files route through a new WriteWithHistory orchestrator
(internal/handler/history.go) which:
- strips six client-supplied audit fields (created_at/by, updated_at/by,
revision, previous_sha) so the client can't forge them
- validates body values against the cascade-resolved field_codes
- enforces filename_format composition (URL basename must match body fields)
- checks locked: defaults (422 mismatch)
- archives prior bytes to <dir>/.history/<base>/<RFC3339Nano>-<sha8>.<ext>
- stamps server-managed audit fields and writes the live file
History-before-live ordering preserves the prior version even on mid-write
crash. previous_sha forms a hash chain across revisions for tamper evidence.
The embedded defaults.zddc.yaml now declares records: entries for mdl, rsk,
and ssr.yaml. RSK rows carry the table-tracking components + row sequence
(filename = <table-tracking>-<row>); MDL rows compose to their own
tracking number; SSR records' identity is the party folder name.
GET <record>.yaml?history=1 returns a JSON list of prior revisions, ACL
gated identically to the live record. dot-segment rejection in
resolveTargetPath protects .history/ from direct client writes.

Replace "Edit YAML" with "Edit row" — navigates to row.url, which
is already the schema-driven form-mode editor URL. The form handler
unwraps virtual-view URLs server-side so SSR and rollup rows route
to their per-party canonical paths automatically; no client-side
URL rewriting needed.
This fills the gap where row-click only opens the form for
complex-type cells (objects, arrays) — for plain scalars it enters
inline edit mode. Right-click → Edit row is now the discoverable
way to reach the full form for any row.
Raw YAML editing remains available via the browse tool directly
(navigate to the file's parent folder and click it in the tree).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three triggers for flushing pending edits:
- Save button in the toolbar — shown only when ≥1 row is dirty,
label reads "Save (N unsaved)". Disappears after a clean settle.
- Ctrl+S (Cmd+S) anywhere on the page, capturing-phase so it beats
the browser's "Save Page As" default.
- focusout of #table-root with a relatedTarget outside the grid —
catches "edit cell, click a header link, expect it to save".
The row-blur trigger stays — moving between rows still flushes. The
new triggers fill the gap when the user edits one row and then leaves
the grid entirely without first navigating to another row.
Dirty marker gets a 4px (was 3px) left swatch AND a faint blue
background tint on the row, so "unsaved" reads as a row state rather
than a small marker on the edge.
editor.setDraft / clearDraftField notify save.onDraftsChanged,
which refreshes the Save button + reapplies the dirty class.
saveRow on 200/201/202 also refreshes the button so it disappears
the moment its row settles.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Opens the row's backing .yaml in the browse tool's YAML editor
(preview-yaml.js — CodeMirror with syntax highlight, lint, Ctrl+S
save). Disabled on multi-row range and unsaved draft rows.
Three URL shapes resolve correctly:
per-party row → <dir>/?file=<file>.yaml
SSR virtual → /<project>/archive/<party>/?file=ssr.yaml
rollup virtual → /<project>/archive/<party>/<slot>/?file=<file>.yaml

The project-level MDL/RSK rollup specs lose `addable: false` and gain
a sibling form schema (default-project-{mdl,rsk}.form.yaml) that
makes `party` a required field. + Add row on the rollup view is now
live: the user types the party name in the Package column, the
server reads `party` from the body, validates that
<project>/archive/<party>/ exists on disk, strips the field, and
writes the row into archive/<party>/<slot>/<date>-<email>.yaml. The
response Location is the synthetic <project>/<slot>/<party>__<file>.yaml
URL so the rollup table client swaps the draft URL cleanly.
Wrong party = 422 with a clear error pointing at the SSR view as the
place to create the folder first. No auto-creation here — the rollup
is for filing deliverables/risks against existing packages, not for
spinning up new ones.

The bwrap engine + OCI engine that lived in internal/convert/runner.go
both leak isolation policy into Go code. Replaced with a single image-
side wrapper that drop-in-shadows pandoc and chromium-browser on PATH.
zddc-server's only contract with the image is now "exec.Command(name,
args) gets you that tool's behavior" — sandboxing, resource caps, and
namespace setup live entirely in shell scripts shipped by the image.
Architecture:
- zddc/runtime/zddc-cgroup-init runs at container start. cgroup v2's
"no internal processes" constraint forbids a cgroup from having both
children and processes; the init script moves PID 1 into a child,
enables +memory +pids in subtree_control, then exec's zddc-server.
Best-effort: degrades cleanly to "no resource caps" if cgroupfs
isn't writable.
- zddc/runtime/zddc-sandbox-exec is the per-call wrapper, symlinked
from /usr/local/bin/{pandoc,chromium-browser}. Creates a transient
cgroup v2 (memory.max + pids.max), then bubblewrap-sandboxes the
real binary at /usr/bin/<name>: --unshare-all, --ro-bind /usr,
--proc /proc, --tmpfs /tmp, --clearenv. Caller's scratch dir comes
in via ZDDC_SCRATCH env and is bind-mounted at the SAME path so
absolute paths round-trip unchanged.
Go simplifications (~250 lines net deletion):
- Runner interface: Run(ctx, binary, stdin, scratchDir, cmd) — no
ToolSpec, no mount list, no engine concept. Single localRunner
implementation; bwrapRunner + containerRunner both deleted.
- health.Probe just looks up pandoc + chromium on PATH; Capabilities
drops engine kinds.
- Convert.go: ToHTML/ToPDF write to a per-call scratch dir under
TMPDIR and pass absolute paths; the wrapper bind-mounts the dir.
No more "/tpl" / "/pdf" mount-point indirection.
- Config drops --convert-pandoc-image, --convert-chromium-image,
--convert-engine, --convert-podman-socket (OCI engine gone) and
--convert-cpus (CPU caps don't apply in the new model — wall-clock
+ memory + pids is the cap set). Defaults raised to match the new
caps the user authorized: mem 512→1024 MiB, pids 100→256,
timeout 30→60 s.
Image:
- zddc/runtime.Containerfile builds the production runtime image
(alpine + bubblewrap + pandoc + chromium + font-noto). Two
COPY statements pull in the wrapper scripts; ln -s symlinks the
shadow names.
- bitnest dev image mirrors this layout under /var/lib/zddc-dev-build/.
Container privilege required:
- Nested bwrap needs the outer container to permit user + mount
namespace creation + MS_SLAVE on root. The default seccomp +
AppArmor profiles block all of these. Quadlet adds:
--cap-add=ALL
--security-opt=seccomp=unconfined
--security-opt=apparmor=unconfined
--security-opt=unmask=ALL
Helm chart sets the equivalent via securityContext (capabilities.
add: SYS_ADMIN, seccompProfile.type: Unconfined, appArmorProfile.
type: Unconfined). Trade-off documented in AGENTS.md: zddc-server
RCE now has near-root power within the container, but the bind-
mount layout still bounds blast radius; bwrap is the real boundary
between zddc-server and untrusted markdown.
Tests: convert_test.go fully rewritten for the new Runner signature.
Drops TestBwrapArgs_* (functionality moved out of Go) and
TestImageTag (no more image refs). All 15 Go test packages green.
Verified live on bitnest: pandoc --version round-trip exits 0
through the wrapper; MD→DOCX produces a valid Word 2007+ file
end-to-end.

Client-side download of the current view — filter + sort + column
order match what's on screen, values pass through util.formatCell so
dates / numbers / booleans render the same way they do in cells. RFC
4180 quoting; UTF-8 BOM so Excel detects encoding without an import
wizard. Sits next to "+ Add row" and shows for every table that
loaded with columns (no HTTP gate — the data is already in the
client), so MDL, RSK, SSR, and both project-level rollups all get
the affordance.

Adds the risk register as a sibling of MDL under archive/<party>/, and
three project-level virtual aggregations at <project>/{ssr,mdl,rsk}:
- SSR aggregates archive/<party>/ssr.yaml; "+ Add row" materializes a
new party folder (mkdir + auto-own .zddc + ssr.yaml). Renames go
through X-ZDDC-Op: ssr-rename, which os.Rename's the party
directory so every row inside follows. Party name doubles as the
folder name (no opaque IDs) and is path-derived on read.
- MDL/RSK rollups list every deliverable / every risk across all
parties with a derived `party` column; "+ Add row" is suppressed
because party affiliation is ambiguous in the aggregate view.
All four virtual roots are declared `virtual: true` in
defaults.zddc.yaml. Spec/form bytes come from six new embedded
defaults (default-rsk.*, default-ssr.*, default-project-{mdl,rsk}.*)
served via a generalized IsDefaultSpec/IsDefaultSpecAbs that replaces
the MDL-only recognizer. Listing synthesis lives in fs/tree.go;
ACL on each synthetic row evaluates against the canonical
archive/<party>/ chain so non-owners see rows read-only. PUT/DELETE
through virtual URLs rewrite to canonical paths in fileapi.go via
sibling-shape blocks that don't touch the ACL gate. SSR row DELETE
returns 405 (delete the party folder via the archive view).

Models virtualreceived.go's request-time path-rewrite pattern. Recognizes
/<project>/{ssr,mdl,rsk}/... URLs and maps row reads/writes back to
canonical files inside <project>/archive/<party>/, so ACL evaluates
against the per-party chain and operator overrides live where the data
does. ListSSRParties and ListRollupRows feed listing-time synthesis.

Replaces the always-spawn-an-OCI-container model with a per-call
bubblewrap sandbox. Pandoc and chromium binaries are baked into the
zddc-server runtime image; each conversion runs them under bwrap's
Linux-namespace isolation. No daemon, no socket, no privileged outer
container, no OCI image pull at conversion time.
Why: the OCI engine paid ≈ 350 MB image pulls + 400 MB persistent
storage + ~300 ms per-conversion startup, plus required either an
on-host daemon socket (zddc-RCE → host-RCE in one hop) or nested
container privileges. bwrap gets the same sandbox properties
(--unshare-all, ro-bind /usr, tmpfs /tmp, clearenv, no-network) at
~5 ms per call and zero external dependencies. This is the same
primitive Flatpak uses for every app launch — battle-tested at scale
for "untrusted-input, short-lived, isolated."
Runner abstraction:
- `Runner.Run` signature: image string → ToolSpec{Image, Binary}.
Both fields populated by entry points; whichever engine is
installed reads the one it needs.
- `bwrapRunner` (new): assembles bwrap argv via `buildBwrapArgs`
helper (testable in isolation), spawns bwrap with the binary.
- `containerRunner` (renamed conceptually to "legacy fallback"):
unchanged behavior, still reachable for hosts that prefer OCI
containers per conversion.
Probe order in health.Probe: bwrap → podman → docker. First hit wins.
Engine kinds in Capabilities: "bwrap" | "podman" | "docker". The
no-engine error message now lists all three.
Config (cmd/zddc-server):
- new --convert-pandoc-binary / ZDDC_CONVERT_PANDOC_BINARY (default "pandoc")
- new --convert-chromium-binary / ZDDC_CONVERT_CHROMIUM_BINARY (default "chromium-browser")
- existing --convert-pandoc-image / --convert-chromium-image kept
for the OCI engine, doc updated to clarify they only apply there.
- --convert-engine helptext lists bwrap first.
Images:
- New `zddc/runtime.Containerfile` — alpine + bubblewrap + pandoc-cli +
chromium + font-noto. Documents build/publish workflow.
- helm/zddc-server-prod/values.yaml.example: runtimeImage default
switched to a placeholder for the new bundled runtime image; bare
alpine NO LONGER works for /.convert (clearly called out in the
comment).
- bitnest dev: /var/lib/zddc-dev-build/Containerfile mirrors the
production runtime image. Quadlet at /etc/containers/systemd/
zddc.container drops the podman-socket mount (no longer needed)
and sets ZDDC_CONVERT_ENGINE=bwrap explicitly to avoid silent
downgrades if a stray podman ends up on PATH.
Tests:
- convert_test.go: fakeRunner / recordingRunner now record ToolSpec.
- New TestToolSpecPopulation pins that both Image and Binary are
filled by every entry point.
- New TestBwrapArgs_SandboxFlagsPresent / MountTranslation /
RejectsBadMountSpec lock in the bwrap argv shape — a refactor that
drops a hardening flag or misroutes a mount fails this loud.
Docs:
- AGENTS.md § "Server-side document conversion" rewritten around
the bwrap-first model with podman/docker as legacy fallbacks.
- ARCHITECTURE.md convert reference updated.
- internal/convert package doc reflects the two-engine probe order.
Verified end-to-end on bitnest: probe reports
engine=bwrap pandoc_binary=pandoc chromium_binary=chromium-browser
on startup. All 15 Go test packages green.

Three UI cleanups against the admin/browse chrome.
Red admin-mode frame (shared/elevation.css)
Was: body { outline: 3px ... ; outline-offset: -3px } — an outline
doesn't reflow content, so in tools that butt their content to the
viewport edge (browse split-pane, archive grid) the frame painted
on top of the first 3px of content.
Now: body.is-elevated::after { position:fixed; inset:0; border:3px;
pointer-events:none; z-index:9200 }. The frame lives in its own
fixed layer above all content, so it never overlaps or steals
clicks; content layout is unchanged.
Project-stage strip (Archive · Working · Staging · Reviewing)
Low-value chrome. Removed entirely:
- delete shared/nav.js + shared/nav.css
- drop the include from every tool's build.sh
(browse, transmittal, form, archive, landing, tables, classifier)
- delete tests/nav.spec.js
- rebuild tables.html (the //go:embed'd baked-in copy)
Project navigation already happens through the directory tree in
browse and the URL bar; the strip duplicated breadcrumb information
without adding capability.

Four targeted test suites that pin the invariants exercised by the
preceding audit refactor. Closes the coverage gaps identified after the
admin-decider consolidation and the .zddc write-path fix.
internal/policy/principal_test.go (NEW)
TestAllowActionFromChainP_TruthTable — 11 cases × 5 actions = 55
assertions covering every (elevated × admin-at-level × action)
combination. Pins the IsActiveAdmin short-circuit: bypass requires
BOTH (in admins) AND Elevated; elevation alone confers nothing;
empty email never matches.
TestAllowActionFromChainP_AdminScopeDepth — root admin reaches every
path; subtree admin matches in their own subtree; subtree admin
does NOT match in a sibling subtree (the chain doesn't carry
sibling admins lists).
TestAllowActionFromChainP_BypassWinsOverWorm — elevated admin
escape hatch in WORM zones, plus the negative control that an
un-elevated admin does NOT bypass WORM.
internal/handler/auth_invariants_test.go (appended)
TestInvariant_ZddcPutMatrix — 16 sub-cases across (root / project /
subtree .zddc) × (root admin / subtree admin / non-admin /
anonymous) × (elevated / un-elevated). Locks down which principal
can PUT which .zddc.
TestInvariant_ZddcDeleteMatrix — 5 DELETE cases.
TestInvariant_UnelevatedAdminNoSilentBypass — 14 anti-bypass probes:
every (admin-flavour × probe-path) tuple where an un-elevated
admin must 403. Single bypass leak → loud test failure.
cmd/zddc-server/main_test.go (appended)
TestDispatchZddcWriteRouting — full dispatcher path coverage:
GET/HEAD route to ServeZddcFile (YAML or virtual placeholder);
PUT/DELETE route through the .zddc-leaf carve-out into
ServeFileAPI; intermediate .zddc.d/ segments still 404 at the
guard.
internal/handler/middleware_test.go (appended)
TestAccessLog_ChainAdminLevelAttribution — 7 cases pinning the
forensic record: root admin → chain_admin_level=0, subtree admin
in scope → chain_admin_level=N, subtree admin out of scope → -1,
un-elevated admin → -1, non-admin → -1, anonymous → -1.
Cross-checks active_admin == (chain_admin_level >= 0) so a future
refactor can't desync them.
92 new sub-cases total. Coverage delta on the policy package:
76.1% → 87.2%; AllowActionFromChainP 0% → 100%;
activeAdminForRequest 7% → 68%.

Single audit pass that removes pre-release back-compat, consolidates the
admin-policy decider, and fixes the .zddc write path.
Field removal — acl.allow / acl.deny:
- Drop ACLRules.Allow / Deny struct fields and mergeLegacyACL().
- Remove walker / lookups / validate / decider branches that read them.
- Migrate every test fixture (YAML strings and ACLRules struct literals)
to acl.permissions: { principal → verb-set }.
- Rewrite both bundled Rego policies (access.rego, access_federal.rego)
to traverse level.acl.permissions; rewrite parity-test helpers.
- Update create-project form (profile page) to collect permissions
instead of allow/deny lists.
Admin decider consolidation:
- Delete zddc.CanEditZddc — strict-ancestor rule retired. Subtree admins
own their own .zddc; the policy decider's IsActiveAdmin short-circuit
is the single bypass site.
- Migrate tablehandler.ServeTable to AllowActionFromChainP — closes the
same Forbidden bug already fixed for /browse.html.
- Drop AccessView.EditableParentChoices and treeEntry.CanEdit (always
true after the retirement). Profile page renders AdminSubtrees
directly for both lists.
- Drop the excludeLeaf parameter from AdminLevelInChain /
IsAdminForChain — no production caller passed true.
Dead code removed:
- policy.AllowWriteFromChain (zero production callers, zero tests).
- zddc.AllowedWithChain (zero production callers; tests deleted).
ModeStrict retirement — federal posture is OPA-only:
- Delete cascade_mode.go / cascade_mode_test.go and the ModeStrict
branches in cascade.go and acl.go.
- Drop --cascade-mode flag, CascadeMode config field, and the
InternalDecider.Mode field.
- Drop the mode parameter from every cascade helper:
GrantedVerbsAtLevel, AllowedAction, EffectiveVerbs,
EffectiveVerbsRange, RoleMembers, MatchesPrincipal,
MatchingPrincipals, WormZoneGrant, PolicyChain.VisibleStart.
- Strip cascade_mode from /.profile/config and
/.profile/effective-policy responses.
- Refresh README / ARCHITECTURE.md to describe federal posture as
"deploy OPA with access_federal.rego" (NIST AC-6); the bundled Rego
is the parent-deny-is-absolute variant. The in-process Go evaluator
implements only the commercial cascade.
Legacy redirects + .admin.css fallback:
- Drop /<dir>/.zddc.html → ?file=.zddc redirect and its test.
- Drop ?zip=1 retired comment + legacy test (handled by the
.zip virtual-URL path; covered by TestServeSubtreeZip).
- Drop .admin.css fallback in profile_assets.go — only .profile.css now.
- Refresh stale "retired" / "back-compat" / "legacy" comment markers.
.zddc write path fix:
- Dispatcher: route only GET/HEAD on .zddc URLs to ServeZddcFile; carve
.zddc out of the dot-prefix guard so PUT/DELETE/POST reach
ServeFileAPI. Before this, .zddc writes 405'd at ServeZddcFile and
the YAML editor's save flow had no live path.
- ServeFileAPI.resolveTargetPath: same .zddc-leaf carve-out so the file
API accepts the path; intermediate dot dirs (.zddc.d/) stay reserved.
- Listing: compute Writable per-file with ActionAdmin for .zddc
(matches the file API's gate) instead of ActionWrite for everything.
- Virtual .zddc placeholder: compute Writable via the same
parentActiveAdmin || ActionAdmin path. Was always false before.
- browse YAML editor canSave: exempt virtual .zddc — the synthetic
body is designed to materialize on PUT.

The audit log now records WHICH chain level conferred admin
authority on each request — 0 for root super-admin, N for a
subtree admin at depth N, -1 for no admin authority. Forensics can
now distinguish:
elevated=true active_admin=true chain_admin_level=0
→ root super-admin acting
elevated=true active_admin=true chain_admin_level=3
→ subtree admin at /<project>/<sub>/<dir>/.zddc acting
elevated=true active_admin=false chain_admin_level=-1
→ opted into admin but no grant on this path (out of scope)
New helper zddc.AdminLevelInChain returns the level index (or -1);
IsAdminForChain becomes a thin wrapper. Middleware's
activeAdminForRequest is rewired to return the level so the audit
emission gets the attribution without double-walking the cascade.
Pre-existing TestServeProfileProjectsCreate's "no .zddc unless body
supplies fields" expectation flipped — the project-create flow now
always seeds admins: [creator] so the test asserts the new
contract.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The rule said: an admin granted in /<dir>/.zddc can edit deeper
.zddc files but NOT the one that grants their own authority.
Intended to prevent self-elevation, peer-addition, and delegator-
removal.
Three problems:
- "Add peers" isn't an attack — it's the common collaboration case.
Project creator can't grant a teammate access without bothering a
super-admin every time.
- "Remove the delegator" doesn't work. Root admin authority lives
in the ROOT .zddc and cascades down regardless of what's in
/<dir>/.zddc; subtree admins can't touch it.
- "Self-elevation" within a subtree is meaningless. They already
have rwcda there.
Replacement model: admins in /<dir>/.zddc OWN /<dir>/ and everything
beneath, including the .zddc itself. They can add collaborators,
modify ACLs, even remove themselves. Self-removal is a recoverable
footgun — root super-admins always retain authority via the root
cascade and can restore.
What stays:
- The admins: field as a load-bearing key (drives IsActiveAdmin
+ sudo-style elevation + WORM bypass).
- Bootstrap via root .zddc hand-editing.
- IsAdminForChain(chain, email, excludeLeaf bool) signature —
ModeStrict / NIST AC-6 deployments can still opt into the strict-
ancestor walk if they need it.
Tests flipped to match the new contract; ProjectCreate flow now
gives the creator real control over their project root.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The /.profile/projects endpoint previously refused anyone without
hasAnyAdminScope. Now it runs the standard decider with ActionCreate
on the parent directory — super-admins still pass via the
IsActiveAdmin bypass branch, and anyone the root .zddc grants `c`
to (e.g. `*@example.com: c`) can self-service a project without
needing an existing admin grant.
Other changes in this commit:
- The new project's .zddc is seeded with the creator's email in
admins: when the request body doesn't supply one — they become
subtree admin of their own project at birth. .zddc edits in
deeper subfolders flow through their authority; strict-ancestor
rule still prevents them from editing /<project>/.zddc itself.
- AccessView gains can_create_project, computed by the same decider
call the endpoint uses — UI and server agree on visibility with
no daylight.
- Profile page splits the subtree-admin template from the create-
project template so the latter mounts on can_create_project,
independent of has_any_admin_scope. Non-admin grantees see the
form; admins keep seeing both.
- Lock-in tests cover the five interesting cases: cascade-granted
user succeeds and becomes subtree admin; stranger gets 404;
elevated super-admin auto-defaults admins; explicit admins list
wins over the default; duplicate-name 409.

Reads (apps resolution, directory listing, file GET, archive index,
profile pages, subtree zip, form render) used policy.AllowFromChain
with email — no admin-bypass branch fired even for elevated admins,
because IsActiveAdmin only landed in AllowActionFromChainP.
Symptom: elevated admin navigating to /browse.html got 403 because
the root cascade has no explicit read grants in my refactored root
.zddc (role memberships + admins only; no acl.permissions). The
app-resolution path's AllowFromChain didn't see admin status.
Fix: new policy.AllowFromChainP that forwards to
AllowActionFromChainP(action=read). Migrate every read-path caller
to the principal-aware variant. The decider's single bypass branch
now fires uniformly across read and write decisions.
Migrated:
cmd/zddc-server/main.go (9 sites)
handler/directory.go (1)
handler/archivehandler.go (2)
handler/zddcfile.go (1)
handler/formhandler.go (3)
handler/projectshandler.go (1; EnumerateProjects sig takes Principal)
handler/subtreezip.go (1)
fs/tree.go (1; uses already-built principal)
profilehandler.go:400 stays on AllowFromChain — it probes ACL for a
DIFFERENT email (the enumeration target, not the request principal),
so admin bypass on the request's principal doesn't apply.

Listing JSON gains a writable bool per file row, computed by running
the policy decider with ActionWrite against the parent-dir chain
(with the same admin-bypass branch the file API uses). Cost: one
extra decider call per file in the listing, sharing the parent
chain so the cascade walk is amortized.
Browse loader stores writable on every tree node. The markdown and
YAML editors read it and gate their canSave + initial mount:
- !writable markdown → Toast UI Viewer (rendered, no edit toolbar,
no caret). Banner above explains why save is disabled.
- !writable YAML → CodeMirror readOnly:'nocursor' (selection for
copy, no caret). Banner above explains why save is disabled.
Both editors gain autofocus:false so keyboard nav in the browse
tree doesn't divert into the editor — arrow keys keep moving through
files and folders without the caret jumping. User clicks (or tabs)
into the editor when they actually want to type.
.zddc files already route through preview-yaml's isZddcFile path;
bare .zddc (no ext) matches because that function checks the
literal name.

Five identical 'if !zddc.IsAdmin { 404 }' guards on /whoami /config
/logs /effective-policy /reindex collapse to a single adminOnly
closure inside ServeProfile. Behavior unchanged — same 404-leakage
property, same elevation-gated authority — just one site to audit
instead of five.

The access log now reports whether the elevated user actually held
admin authority on the request's target path — i.e., whether the
single bypass branch in policy.InternalDecider.Allow would have
fired here. Three states fall out:
elevated=false, active_admin=false: normal user
elevated=true, active_admin=false: opted into admin but no admin
grant on this path (subtree-
admin out of scope)
elevated=true, active_admin=true: admin authority active for
this path — WORM/ACL bypass
Implementation: AccessLogMiddleware gains a cfg parameter and calls
activeAdminForRequest at log emission, walking the closest existing
ancestor (same logic the file API uses to build its ACL chain).
The cascade is mtime-cached upstream so the per-request cost is one
map lookup in the common case.
Audit value: a reviewer can spot at a glance whether a destructive
write was authorized by ACL or by admin bypass. Plus "elevated=true
active_admin=false" rows surface users who tried to elevate outside
their actual scope.

authorizeAction (file API) and executePlanReview both used to make
their own IsAdmin / IsSubtreeAdmin / CanEditZddc calls before falling
through to the decider. After this commit every admin/elevation
branch is in policy.InternalDecider.Allow — the handlers just call
AllowActionFromChainP with the principal and let the decider decide.
fileapi.go authorizeAction:
- ~60 lines → ~20 lines.
- Three early-outs (IsAdmin / IsSubtreeAdmin / CanEditZddc) removed.
- .zddc strict-ancestor rule preserved: AllowActionFromChainP detects
action == ActionAdmin (serveFilePut tags .zddc writes that way) and
applies excludeLeaf=true to IsAdminForChain.
planreview.go executePlanReview:
- Two preflight checks now flow through AllowActionFromChainP.
- The "is admin OR is subtree admin? else fall through to decider"
braid collapses to one decider call per target.
- Behavior preserved: subtree-admin authority required for the
reviewing/staging workflow roots (strict-ancestor via ActionAdmin),
WORM-cr authority required for received/<tracking>/ creation.
Plan Review and Accept Transmittal tests still pass, lock-in
invariants still hold (un-elevated admin denied, elevated admin
bypasses, subtree scope, strict-ancestor, etc.).
Next: remove the now-dead IsAdmin / IsSubtreeAdmin / CanEditZddc
helpers (still referenced by profilehandler and authcheck), or keep
them — they're not on a hot path and the migration there is its own
commit.

Lays the rails for the consolidation refactor — the decider gains a
single admin-bypass branch at the top of InternalDecider.Allow, and a
new principal-aware entry point computes IsActiveAdmin from chain +
Principal.Elevated. No caller uses the new path yet, so behavior is
unchanged; lock-in tests stay green.
AllowInput.User.IsActiveAdmin bool // caller-computed bypass flag
AllowActionFromChainP(ctx, d, chain, p, path, action) (bool, error)
The decider's branch:
if input.User.IsActiveAdmin { return true, nil }
is the ONLY admin escape hatch in the package. Strict-ancestor rule
for .zddc edits is preserved inside AllowActionFromChainP via
IsAdminForChain(chain, email, excludeLeaf=true) when action==ActionAdmin.
Email-only entry points (AllowFromChain, AllowActionFromChain) leave
IsActiveAdmin=false implicitly — they're for read-path callers that
don't need admin bypass (directory listing, archive index, profile
read endpoints).
Next commits: migrate authorizeAction and plan-review's pre-flight
to AllowActionFromChainP, then delete the scattered IsAdmin/
IsSubtreeAdmin/CanEditZddc early-outs.

Pure cascade-walk admin check that replaces IsAdmin (root only) +
IsSubtreeAdmin (cascading) + CanEditZddc (strict-ancestor) under one
signature once callers migrate.
IsAdminForChain(chain, email, excludeLeaf bool) bool
- chain is built for the request path, so subtree-admin scope falls
out naturally (a chain rooted at /foo/ will only surface admins:
entries at root and any level up to /foo/).
- email "" never matches (anonymous refusal).
- excludeLeaf=true drops the deepest level — implements the strict-
ancestor rule for .zddc edits. At chain length 1 (root) the
exclusion degenerates, preserving the bootstrap super-admin path.
- Elevation-INDEPENDENT — the caller wires Principal.Elevated around
the result. Keeps this function a pure cascade query, testable
without context plumbing.
Property tests pin: super-admin matches at depth; subtree admin
matches inside scope, blocked outside; excludeLeaf hides leaf admins
(self-elevation prevention); excludeLeaf at root falls back to root;
empty email refused; role references in admins resolve through the
chain; role defined at leaf is invisible above under excludeLeaf.
Old IsAdmin / IsSubtreeAdmin / CanEditZddc stay in place during the
migration — next commits move callers across, last commit removes
them.

Baseline test battery that pins the current auth-decision behavior so
the upcoming consolidation refactor (single bypass site in
InternalDecider.Allow) is validated against a green baseline.
Each test names one invariant; failure messages identify exactly
which property regressed. Coverage:
- Un-elevated admin cannot bypass WORM (PUT to issued/ → 403).
- Un-elevated admin cannot edit .zddc (Principal.gate() blocks).
- Elevated admin bypasses WORM (positive control).
- Elevated subtree admin writes within scope, blocked outside it.
- Strict-ancestor rule: subtree admin cannot edit own subtree's
.zddc, can edit deeper .zddc.
- Empty email never matches.
- WORM cr survives for un-elevated document_controller (create OK,
overwrite still stripped).
- project_team has read-only outside their auto-own home.
- Forward-auth /.auth/admin gates strictly on ROOT admins:.
wormbypass_test.go retained as the original repro of the live bitnest
observation (un-elevated user write succeeded under --no-auth=1).

The header toggle alone is easy to miss — admin elevation bypasses
WORM zones and ACL silently, so an admin who forgot they were
elevated could write into received/ or issued/ thinking they were
operating under their normal grants.
Two reinforcing affordances when the zddc-elevate cookie is set:
- body.is-elevated paints a 3px red outline around the entire page,
visible from any scroll position and inside any tool surface.
- A sticky red banner sits across the top with a pulsing dot, an
explicit warning ("write access bypasses WORM and ACL safeguards"),
and a one-click "Drop admin" button that clears the cookie + reloads
so the user can disarm without hunting for the corner toggle.
Both render on every page load via shared/elevation.js — applies to
every tool that includes the elevation slot, plus any tool that loads
the shared bundle even without a toggle host (the iframed classifier
inside browse's grid mode, etc.). Wired before the access fetch so
the banner appears immediately instead of waiting on /.profile/access.

Two layers shipped together since the second builds on the first.
LAYER 1 — reviewing/ + Plan Review scaffolding
- reviewing/ is now a real folder under each project, populated by the
Plan Review composite endpoint. The old reviewing/ virtual aggregator
handler is retired.
- POST /<project>/archive/<party>/received/<tracking>/ with X-ZDDC-Op:
plan-review scaffolds physical workflow folders under reviewing_root
and staging_root, each carrying .zddc.received_path pointing back at
the canonical submittal. Idempotent re-runs match by received_path
and re-converge the ACL.
- Virtual received window: when listing or writing under
<workflow>/received/, the server resolves through the canonical
archive/<party>/received/<tracking>/ via the workflow's
.zddc.received_path. Writes get rewritten to
<workflow>/<base>+C<n><suffix> so review comments land in the
workflow folder and never touch the WORM archive.
- Cascade defaults declare on_plan_review per project so the
reviewing_root and staging_root are configurable.
LAYER 2 — browse context-menu workflows
- Accept Transmittal: right-click a transmittal folder in
archive/<party>/incoming/ → validates ZDDC folder + filename
conformance, atomic-renames the folder to
archive/<party>/received/<tracking>/ (WORM zone), and optionally
chains into Plan Review in the same composite request. Re-acceptance
with a different revision merges file-by-file; WORM forbids
overwrite of an existing filename.
- Stage / Unstage: right-click files in working/<…>/ → "Stage to…"
with picker of existing staging transmittal folders + inline
"New transmittal folder…" create; right-click files in
staging/<…>/ → "Unstage to working/" defaulting to the user's
working/<email>/ home. Reuses the file-API move primitive.
- Create Transmittal folder: right-click the staging/ pane → prompts
for a ZDDC-conforming folder name with live validation; mkdir,
then navigate to the new folder URL where the transmittal tool
serves the editor.
- Supporting infrastructure: new CanonicalFolderAt cascade lookup +
X-ZDDC-Canonical-Folder response header so the browse SPA can
scope-gate menu items without re-implementing the cascade
client-side.

The cell-editor was already complete (drafts, row-blur saves, etag
concurrency, validation). This commit adds the missing row-level ops:
- "+ Add row" appends a draft row inline; first cell focused. Row-blur
POSTs to <dir>/form.html (the existing form-create endpoint); 201
swaps the synthetic id for the server-returned URL/ETag. Empty rows
the user walks away from are silently discarded.
- Right-click a row → "Delete row" (or "Delete N rows" when a cell
range spans multiple rows). DELETE the row YAML with If-Match; 412
surfaces a conflict warning.
- Multi-row clipboard paste creates new rows for grid content that
extends past the last existing row, instead of dropping cells past
the end. Each new row saves via its own row-blur.
- Empty rows now have a 2.4em minimum height so a freshly-added row
is visible. Without the floor it collapses to cell-padding (~8px)
and looks like a divider line.
Server-side: no new endpoints. Form-create (POST <dir>/form.html →
201 + Location) and file-API DELETE carry the new client capabilities.

Replace `?zip=1` / `?convert=docx|html|pdf` query forms with path-suffix
URLs that look like ordinary files. `<dir>.zip` and `<file>.docx` /
`.html` / `.pdf` are virtual files served by the dispatcher when stat
fails at the requested path AND the corresponding base resource exists:
GET /Project-1/archive.zip ← if archive/ is a real directory
GET /Project-1/notes.docx ← if notes.md exists
Real on-disk files always win — a genuine archive.zip in the tree
serves its bytes normally. The virtual forms only fire when nothing
real is there.
Why: the URL form lets clients emit plain <a href> without query-
string handling; `curl -O` writes a sensible filename; mirror tools
pick up the path through normal recursion; the protocol surface
becomes "every URL is a file". Bash + filesystem mental model.
Server:
- New helpers handler.RecognizeVirtualSubtreeZip /
RecognizeVirtualConvert (in subtreezip.go and converthandler.go).
- Dispatcher's stat-fails branch checks them between IsDefaultMdlSpec
and MatchAppHTML. ACL is enforced on the base resource (the source
directory for zip, the .md source for convert).
- Three legacy query-form branches removed from main.go.
Client:
- browse/js/download.js: `dir + '.zip'` instead of `dir + '/?zip=1'`.
- browse/js/preview-markdown.js: convert anchor hrefs become
`<mdUrl-minus-.md>.<fmt>` instead of `<mdUrl>?convert=<fmt>`.
- shared/zddc-source.js downloadConverted: same transform.
Tests: subtreezip_test.go test URLs cosmetically updated to the new
shape (the handler is exercised directly, so the URL is metadata only,
but the test reads better).

Polish pass after the big refactor in 2d114fc.
== Header elevation slot propagated ==
shared/elevation.{js,css} surface a header checkbox for admins.
30-minute sudo-style cookie window (Max-Age=1800, SameSite=Lax).
Only renders when /.profile/access reports can_elevate=true; quiet
for non-admins. Slot added to all 7 tool templates and concat'd
into all 7 build.sh files; admin in any tool now sees the toggle.
Three text-rename ride-alongs in archive/classifier/transmittal
templates: "Add Local Directory" → "Use Local Directory" (the same
rename that landed in browse earlier in this branch).
== Docs ==
- CLAUDE.md gets an "Admin elevation is sudo-style" paragraph in
the "Things that bite if you forget" section.
- AGENTS.md gets a dedicated "Admin elevation (sudo-style)" section
alongside "Bearer tokens" — same depth as the existing auth docs.
== Helper file splits ==
The retired form editor's shared helpers got bundled into a single
zddc_admin.go in the cleanup; that name is now misleading. Split by
concern:
- admin_helpers.go: hasAnyAdminScope (the only admin-specific helper)
- paths.go: resolvePath, urlPathOf, chainDirs (URL ↔ filesystem path
math — used by several profile / zddc-file handlers)
- profile_assets.go (renamed from zddc_admin_assets.go): custom CSS
pipeline. URL renamed from /.profile/zddc/assets/ → /.profile/assets/
since /.profile/zddc/ no longer hosts an editor.
- treeEntry moves to profilehandler.go (alongside AccessView, its
only consumer).
- writeError moves to profileprojects.go (its only consumer).
== Smell cleanup ==
- zddc.HasAnyAdminGrant(fsRoot, email) — new elevation-independent
primitive that walks the cascade and reports whether email is named
in any admin: list anywhere. Replaces the synthetic-elevated probe
hack in enumerateAccess (`Principal{Email, Elevated: true}` was
"lying" to the elevation gate to ask what it would say). The handler's
hasAnyAdminScope collapses to a 4-line wrapper that gates on
p.Elevated and delegates.
- Access-log middleware records `elevated` per request, so forensics
can distinguish "admin acting as user" from "admin exercising power."
- browse/js/app.js's ?file= deep link walks multi-segment paths. Each
intermediate segment is matched + expanded; the leaf gets
selected/previewed. Auto-shows hidden when any segment starts with
. or _. Silently no-ops on unresolved segments.

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

Adds a UI checkbox next to the existing Sort dropdown that surfaces
hidden entries when ACL would otherwise allow read. Default off
(matches today's filtered behavior). On toggle, browse re-fetches
the current directory with ?hidden=1 and re-renders.
┌─ browse toolbar ─────────────────────────────────────────────┐
│ Sort: [Name (A→Z) ▾] ☐ Show hidden │
└──────────────────────────────────────────────────────────────┘
Server-side surface:
- internal/fs/tree.go ListDirectory gains an `includeHidden bool`
parameter. The .-prefix filter (previously hard-coded) now also
drops _-prefix entries (matches dispatch's reserved-prefix guard)
and honors the new flag.
- internal/handler/directory.go reads `?hidden=1` from the request
and threads it through.
- cmd/zddc-server/main.go dispatcher relaxes its dot-prefix and
_-prefix guards for GET/HEAD when `?hidden=1` is set, so clicking
a hidden entry's link works. `_app/` (apps cache) stays
unconditionally reserved — those bytes must go through the apps
resolver. Writes to hidden paths stay blocked (the file API has
its own segment check that the flag does NOT relax).
- internal/listing/listing.go: signature parity (the lower-level
helper that's used by tests + non-cascade listing paths).
Security model unchanged: the ACL chain on the parent dir is the only
real gate. Whoever can read the dir can see its contents — toggling
"Show hidden" just stops the client-side filter from masking
.-prefixed and _-prefixed entries. Hidden paths today:
• <dir>/.zddc ACL YAML — already exposed via /.profile/zddc
• <dir>/.converted/<base> cached MD→DOCX/HTML/PDF, same sensitivity as source
• <root>/.zddc.d/tokens/ per-token metadata; filename = sha256(token)
so not bearer-usable. Default root ACL
restricts to admins; matches /.tokens UI.
• <root>/.zddc.d/logs/ access logs; same admins-only audience
• <root>/_app/ cached upstream tool HTML (public)
• <root>/_template/ install.zip scaffolding (public)
None of these contain bearer credentials or secret material that the
existing ACL doesn't already gate. The walls are still the cascade.
The HTML→PDF path produced PDFs where content extended past the
right margin of each letter page. Two contributing causes in
viewer-template.html's @media print rules:
1. .content-wrapper carries max-width: min(900px, 100%) from the
screen layout. The print override set width: 100% but didn't reset
max-width. Chromium's --print-to-pdf renders at the full page
width (816px for letter at 96dpi) and only clips at print time,
so without max-width: none the element actually extends past the
~624px printable area.
2. Tables, preformatted blocks, and long URLs had no print
containment. A wide <pre> or a <table> with many columns would
blow out the right edge even when the parent constraints held.
Fixes applied to @media print:
- html, body, .app-container: explicit width: 100% + max-width: 100%
to be sure the print viewport flows top-down with no horizontal
creep at the layout root.
- .content-wrapper: max-width: none + width: 100% (was just width).
- .content-page: width: 100% added (was just max-width: none).
- .document-content: max-width: 100% + box-sizing: border-box so
the existing 0.5in horizontal padding stays inside the page.
- pre/code/table/blockquote/img/video: max-width: 100% +
overflow-wrap: break-word; <pre> additionally white-space:
pre-wrap + word-break: break-word so unbreakable token runs
(URLs, paths, command lines) wrap instead of overflowing.
- table: table-layout: fixed so columns shrink to fit rather than
forcing horizontal scroll/overflow.
Both source files (pandoc/viewer-template.html and the embed copy at
zddc/internal/convert/viewer-template.html) updated and verified
identical with diff -q.
The HTML→PDF stage failed with:
Creating shared memory in /dev/shm/.org.chromium.Chromium.XXXXXX
failed: Read-only file system (30)
Unable to access(W_OK|X_OK) /dev/shm: Read-only file system (30)
Chromium tries to put its IPC shared-memory segments under /dev/shm
by default. Our container runs --read-only with /dev/shm inherited
from the image (which makes it read-only too). The well-known fix is
the --disable-dev-shm-usage chromium flag, which routes those
allocations to /tmp instead.
/tmp is a writable tmpfs we already set up. Bump its size from
128 MiB to 256 MiB so chromium has room for both its user-data-dir
and the redirected shared-memory segments. A small PDF flow used
~64 MiB free of 128 MiB available; doubling gives headroom without
materially changing the pod's memory footprint (tmpfs only consumes
RAM for bytes actually written).
The discardable_shared_memory_manager warning ("Less than 64MB of
free space in temporary directory") in the prior chromium log was a
symptom of this same /tmp-too-small condition; the bump quiets it
too.
Other warnings in the log (dbus connect failures) are not load-
bearing — chromium falls back gracefully when dbus is absent. No fix
needed there.
zddc-server can now invoke podman as a CLIENT against a remote socket
instead of creating containers in its own process. The sidecar pattern
in tnd-zddc-chart will use this so zddc-server's own pod stays
unprivileged (only the podman-system-service sidecar runs privileged).
New surface:
--convert-podman-socket / ZDDC_CONVERT_PODMAN_SOCKET
e.g. unix:///var/run/podman/podman.sock
Empty (default) → local mode (podman creates containers in
zddc-server's own filesystem namespace).
Non-empty → remote mode: `podman --remote --url=<this> run …`
dispatches each container request to whatever process owns the
socket. Typically a `podman system service` sidecar in the same
Kubernetes pod.
--convert-scratch-dir / ZDDC_CONVERT_SCRATCH_DIR
Host-side directory for per-conversion intermediates (template,
HTML, PDF). In remote mode this MUST be a path the sidecar sees
at the same mountpoint — typically a shared emptyDir at /work
in both containers. Empty = $TMPDIR (local-mode default).
Runner behaviour:
local mode → unchanged. `podman run --userns=host --rm --pull=missing
--network=none --read-only …`. `--userns=host` stays so nested-podman
on a privileged host (the previous chart shape) keeps working for
anyone still using it.
remote mode → `podman --remote --url=<sock> run --rm --pull=missing
--network=none --read-only …`. `--userns=host` is dropped because
the sidecar is rootful inside its own privileged container and
doesn't need userns juggling.
Health probe gains a Mode field ("local" | "remote") and, in remote
mode, runs `podman --remote --url=<sock> version` to confirm the
sidecar's socket is reachable. Unreachable-socket → 503 with a clear
reason (sidecar may still be starting up); reachable → ready.
Capabilities log now includes engine_version + mode + remote_url for
easier debugging of "which podman is actually doing the work".
No tests removed — the existing fake-runner table covers both modes
since the runner's args are uniform (remote prefix is the only thing
that differs).
When zddc-server runs inside a Kubernetes pod and shells out to
`podman run`, the inner podman tries to set up its own user namespace
via /usr/bin/newuidmap. The mapping fails inside the pod's namespace
even with privileged: true:
newuidmap: write to uid_map failed: Invalid argument
Error: cannot set up namespace using "/usr/bin/newuidmap": exit status 1
Adding --userns=host to the inner `podman run` tells it to reuse the
caller's user namespace instead of creating a new one — newuidmap
isn't invoked. The chart already runs the pod privileged so reusing
its userns adds no new privilege; --cap-drop=ALL + --network=none +
--read-only + --tmpfs continue to isolate the inner container.
On a bare-metal host invocation, --userns=host means "no userns
remapping at all", which is the default for rootful podman and works
identically to the prior behavior — the bitnest test setup and any
laptop dev runs are unaffected.
Smoke-tested locally with the exact flag set: pandoc/latex:latest in
a --userns=host --read-only container produces valid HTML from
`# Hello world` on stdin.
mdedit/ is gone. Its functionality moved into browse's preview plugin
(browse/js/preview-markdown.js) — YAML front matter editing, outline,
and on-demand DOCX/HTML/PDF download all happen there. Browse is the
default_tool for working/ + reviewing/ as of the previous commit, so
existing URLs of the form /<project>/working land on browse without
operator action.
Removed:
• mdedit/ source tree (Toast UI app, CSS, JS, template, build.sh)
• zddc/internal/apps/embedded/mdedit.html (//go:embed blob)
• tests/mdedit.spec.js + the "mdedit" project in playwright.config.js
• mdedit entries in zddc/internal/apps/embed.go (//go:embed, var,
switch case in EmbeddedBytes)
• "mdedit" in zddc/internal/zddc/validate.go AppNames + the matching
error-message app list
• "mdedit.html" branch in zddc/internal/apps/handler.go MatchAppHTML
• mdedit case in tests (handler_test.go, validate_test.go,
zddchandler_test.go) — test fixtures now use browse/classifier
• mdedit from build (per-tool build.sh loop, tool-list literals,
composer cards) and shared/build-lib.sh ZDDC_RELEASE_TOOLS
• mdedit from freshen-channel's tool list and usage banner
• mdedit-specific paragraphs in AGENTS.md and ARCHITECTURE.md;
Markdown Editor section in ARCHITECTURE.md rewritten to point at
browse/js/preview-markdown.js
• mdedit from CLAUDE.md, README.md, zddc/README.md tool lists
Historical mdedit_v*.html / mdedit_v*.html.sig files in
/srv/zddc/releases/ on the deploy host are immutable history — they
stay where they are. The next ./build release cut will simply not
produce new mdedit_v* artifacts.
Flip default_tool from `mdedit` to `browse` (which now ships a Toast UI
markdown editor plugin in its preview pane) at:
• paths."*".paths.working
• paths."*".paths.working.paths."*" (per-user homes)
• paths."*".paths.reviewing
available_tools at those levels drops `mdedit` and adds `browse` next
to `classifier`. Operator overrides per .zddc cascade still work; only
the embedded baseline changes.
Test fixtures updated:
• lookups_test.go — DefaultToolAt assertions for working/+reviewing/
• availability_test.go — AppAvailableAt + DefaultAppAt for working/+
reviewing/+per-user home
• main_test.go — dispatch route asserts "ZDDC Browse" (was "ZDDC
Markdown"); Apps cascade fixture swaps mdedit
for browse so the live route fetches the right
embedded HTML
New endpoint GET /<path>/foo.md?convert=docx|html|pdf renders a markdown
source on demand. Surfaced as the Download buttons in browse's markdown
editor (separate commit).
Execution model — two upstream container images, lazy-pulled:
• docker.io/pandoc/latex:latest — MD→DOCX, MD→HTML (entrypoint pandoc)
• docker.io/zenika/alpine-chrome — HTML→PDF (entrypoint chromium-browser)
No custom image build. The runner passes --pull=missing on every podman/
docker invocation so the operator only needs the runtime installed —
first request pulls the image, subsequent requests use the local cache.
Overrides: --convert-pandoc-image / --convert-chromium-image (and the
matching ZDDC_CONVERT_* env vars). Engine: --convert-engine (podman
preferred, docker fallback). Resource caps: --convert-mem-mib (512),
--convert-cpus (2), --convert-pids (100), --convert-timeout (30s).
PDF flow is two-stage: pandoc renders the markdown through the embedded
viewer-template.html to standalone HTML, then chromium prints that HTML
via --print-to-pdf. Preserves the print-media CSS already authored in
viewer-template.html rather than going through pandoc's LaTeX template.
Each conversion runs in a throw-away container with --rm --network=none
--read-only --tmpfs=/tmp --cap-drop=ALL --security-opt=no-new-privileges
--env=HOME=/tmp plus a bind-mounted scratch dir for I/O. Pandoc reads
markdown from stdin / writes to stdout; the viewer template lives at
/tpl (ro). Chromium reads HTML from a read-write bind mount at /pdf
and writes the PDF to the same mount; the host reads it back. No shell
wrappers, no shell quoting — argv flows straight into each image's
entrypoint.
On-disk cache at <dir>/.converted/<base>.<ext> with mtime synced to the
source. Fast path is a stat-and-serve with no exec; slow path
singleflights concurrent requests for the same target. PUT/DELETE/MOVE
on the source .md purges the .converted/ sidecars.
Per-project template variables (client/project/contractor/project_number)
come from a new .zddc `convert:` cascade block, walked leaf→root with
per-key latest-wins. Filename-derived variables (title, tracking_number,
revision, status, is_draft) come from a new zddc.ParseFilename helper.
If neither podman nor docker is on PATH, the endpoint serves 503 with
a clear Retry-After. The rest of the server keeps working.
This is the first os/exec site in the codebase. The hardening in
internal/convert/runner.go — context.CancelFunc → process kill,
cmd.WaitDelay, platform-specific SysProcAttr (Setpgid + Pdeathsig on
Linux), minimal env, stdout cap via limitWriter, stderr ring buffer —
sets the pattern for any future shell-outs.
Public surface:
convert.ToDocx(ctx, source, meta) / .ToHTML / .ToPDF
convert.Probe(ctx, engineOverride) → install Runner if engine present
convert.SetImages(pandoc, chromium)
convert.ConfigureLimits(memMiB, cpus, pids, timeout)
convert.Available()
Container handler at internal/handler/converthandler.go; dispatcher
branch in cmd/zddc-server/main.go inserts the convert lookup after the
existing ACL gate, reusing the source file's read policy verbatim.
