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.

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.

Final phase of the editable-cell sequence. Adds linear undo
(Ctrl/Cmd+Z), range selection (Shift+arrow, Shift+click), bulk
delete (Delete/Backspace), and fill-down/right (Ctrl+D / Ctrl+R)
across the selected range. Skips redo, drag-fill handle, and
formulas — those were the deferred items from the architecture
report's "build what spreadsheet refugees miss most in week one"
recommendation.
Undo (tables/js/undo.js):
- Linear command stack, depth 50, session-local. Each Command
is { cells: [{rowId, field, oldValue, newValue}, ...] }.
Single edits push a one-cell Command; bulk operations push
one Command spanning all affected cells so a single Ctrl+Z
reverts the whole group.
- Replay logic: for each cell in the popped command, compare
oldValue to the row's stored data. If they match → clear the
draft (the user's edit reverts to baseline). Otherwise →
setDraft to oldValue (intermediate state). Then app.repaint().
- Hotkey: document-level keydown for Ctrl/Cmd+Z. Bails when the
active element is an INPUT / TEXTAREA / contentEditable so
the browser's intra-input undo wins inside a focused editor.
- Pushed by every edit path: editor.commit, editor.bulkClear,
editor.bulkFill. Phase 4's clipboard.applyPaste path will
push from a future iteration — current paste tests don't
cover undo, but the wiring is symmetric.
- Why local-only and no redo: per the architecture report —
shared undo is conceptually broken under last-writer-wins;
redo is a power-user nicety we can add later as a parallel
forward stack (~10 lines).
Range selection (tables/js/editor.js):
- New state: app.state.range = {anchor, focus} | null. Anchor
is the cell where the range started; focus is the current
edge. The cell at focus also has tabindex=0 (the keyboard
focus owner).
- Shift+ArrowDown/Up/Left/Right: extends focus by one cell,
re-applies --in-range class to every cell in the bounding
rectangle.
- Shift+click on a cell: extends the range from anchor to the
clicked cell. Plain click clears the range.
- Escape clears both selection and range.
- Visual: --in-range cells get a fainter background; the
--selected cell (focus) keeps its bright outline so the
anchor/focus distinction is visible.
Bulk delete:
Delete or Backspace in nav mode (no editor mounted) clears
every cell in the current range, setting each to null in the
draft buffer. One undoable Command spans the whole range so
Ctrl+Z restores all cells together.
Fill-down / fill-right:
- Ctrl+D fills the top row's value down through the range
(Excel/Sheets convention). Each cell in the column below
the source row picks up the source row's effectiveCellValue
for its column. Cross-column variation preserved.
- Ctrl+R fills the left column's value right through the
range. Symmetric to Ctrl+D.
- Both push a single multi-cell Command.
Bug fix shipped alongside:
editor.commit and editor.cancel now ev.stopPropagation() in
addition to preventDefault. Without it, the input's keydown
on Enter bubbled up to the table's onCellKey listener AFTER
setSelected moved focus to the next row, which then re-fired
enterEdit on the new cell — a confusing "I committed but
landed back in edit mode" UX. The probe-driven test for the
single-cell undo path surfaced this; same root cause for any
focus-on-target-then-bubble pattern. Tab and Escape get the
same treatment for symmetry.
Tests (7 new Phase 5 specs, total 44 in tests/tables.spec.js):
- Ctrl+Z reverts a single cell edit to prior value — types in
one cell, asserts the draft applied, presses Ctrl+Z, asserts
the cell returned to its original AND the draft buffer is
empty (returned to baseline → no draft).
- Shift+ArrowDown extends range selection — verifies two cells
carry --in-range class.
- Shift+click extends range from anchor to clicked cell —
verifies a 2x3 selection produces 6 in-range cells.
- Delete clears every selected cell — verifies a 2x2 selection
produces 4 null drafts.
- Ctrl+D fills the top row down through the range — verifies
the second row's title cell takes the first row's title.
- Ctrl+Z reverts a bulk fill in one step — verifies a single
Ctrl+Z restores the original value AND clears the draft.
- undo stack depth caps at 50 — pushes 60 commands, asserts
depth saturates at 50 (oldest 10 dropped).

Cell edits now actually persist. Row-level batch save fires on
row-blur (selection moves to a different row); the request is one
PUT with the full merged row (server-side data + client drafts)
and If-Match: <etag> for optimistic concurrency. Conflict and
validation responses are surfaced inline; drafts are NEVER silently
discarded — when the server says no, the user's typing stays put
until they explicitly reload or replay.
Architecture (per the research synthesis from earlier in this
sequence):
- ETag tracking: context.js readRows captures the per-row ETag
from HttpFileHandle's response header on the initial GET.
Stashed at row.etag alongside row.data and row.yamlUrl. Phase 3
reads it; later phases (undo replay) inherit it.
- Row-blur trigger: editor.js setSelected calls a new
notifySelectionChanged() hook after selection lands. save.js's
onSelectionChanged tracks _previousSelectedRowId; when it
changes AND the previous row had drafts, fires saveRow(prevId).
Fire-and-forget — don't block the user's flow on the network.
- save.saveRow flow:
1. mergeRow(row.data, drafts) → full updated row.
2. js-yaml dump → wire body.
3. PUT row.yamlUrl, body, headers={Content-Type, If-Match}.
4. Branch on response status:
- 200/201 → success: clear drafts + invalid marks, capture
new ETag from response, replace row.data with merged.
- 202 → outbox queued (downstream client offline):
clear drafts (the outbox owns them now), mark row queued.
- 412 → stale: drafts STAY; mark row stale; show
status-bar prompt with [Use mine] / [Reload] buttons.
- 422 → server validation failed; body has
{errors: [{path, message}]}; mark each cell invalid via
a red-corner CSS marker + title-attribute tooltip.
- other → mark errored; drafts stay.
- Conflict resolution UX:
- "Use mine" replays the user's drafts onto fresh server
state. Re-GETs the row to learn the new ETag + new server
data, replaces row.data with the fresh server values, then
re-PUTs the merge of fresh + drafts. This is client-side
field-level last-writer-wins: fields the user did NOT
touch get the server's new values automatically; only
fields the user changed override server state. No JSON
Patch endpoint required — pure client logic on top of the
existing whole-row PUT path.
- "Reload" drops drafts entirely, re-GETs the row, repaints.
- Validation error display: per-cell red-corner triangle
(Excel-style) plus title-attribute tooltip on hover. Marker
keyed off data-col-idx + the column's field; survives until
the next edit on that cell or the next paint() cycle.
- beforeunload safety net: any rows with drafts at unload time
get one fire-and-forget save attempt. Modern browsers limit
what beforeunload can do; a follow-up could add fetch's
keepalive flag for a more reliable last-shot.
UI surfaces:
- Per-row state classes drive a left-border swatch in the first
cell:
--dirty subtle blue (uncommitted changes)
--saving muted grey (PUT in flight)
--queued warm yellow (outbox accepted)
--invalid orange (server 422)
--stale warning amber (server 412 — also tints row bg)
--errored red (other failure — also tints row bg)
These re-apply across re-paints via save.markAllDirtyRows()
called from main.js's paint() hook (innerHTML='' wipes them).
- #table-status doubles as the conflict prompt host. When a row
goes stale, the bar shows
"This row was changed by someone else. [Use mine] [Reload] [×]"
and the row-id it's bound to is stored on data-row-id so a
successful reload of that row dismisses the prompt.
Outbox (downstream client) interaction:
The cache layer's PUT-replay queue intercepts saves transparently.
On local network failure the cache returns 202 with
X-ZDDC-Cache: queued; we treat 202 as "succeeded for now" —
drafts clear (the outbox owns them and will replay), but the
row stays marked --queued so the user knows the write hasn't
reached upstream yet. When the cache replays and gets a
real 200/201/412/etc., the row state will reflect that on next
read (next paint cycle / page refresh).
Tests (4 new Phase 3 specs, total 31 in tests/tables.spec.js):
- row-blur fires PUT with merged drafts + If-Match. Edit a
cell in row 0, Enter (commits + moves to row 1). Verifies
PUT went out with the right URL, the merged YAML body
contains the new value AND the unchanged fields, and the
If-Match header carries the original ETag.
- 412 conflict marks row stale + shows status prompt. Verifies
the row gains the stale class, the status bar appears with
both [Use mine] and [Reload] buttons, AND the draft is
preserved (never silently dropped on conflict).
- 422 validation errors mark cells invalid. Verifies multiple
field errors → multiple red-corner cells.
- Reload button drops drafts and refreshes. Verifies the bar
hides and drafts clear after a successful reload GET.
Setup: a small page.route helper intercepts http://test.local/*
PUTs and GETs, lets each test queue the next response via
window.__nextResponse, and captures requests at
window.__capturedRequests for inspection. Test fixtures use
absolute http URLs in row.yamlUrl so the route catches them.

First step toward the Excel-like editable-table the user asked for.
Architecture decisions in this phase came from a focused research
pass over Notion / Airtable / AG Grid / Handsontable / Glide / W3C
ARIA APG; the design notes are in this commit's predecessor as a
research synthesis. Five phases planned; this is phase 1 of 5 and
ships the cell-selection + keyboard-navigation + per-cell editor
mount-on-demand foundation. Edits in this phase live in a client-
side draft buffer only; row-level save + ETag conflict UX is
phase 3.
Scope:
- ARIA grid pattern verbatim (W3C WAI-ARIA APG): role=grid on the
table, role=row on rows, role=gridcell on cells, roving
tabindex (only one cell carries tabindex=0; arrows move it).
This makes the grid one tab stop in the page tab order — the
documented spreadsheet UX, and also the basis for screen-reader
correctness.
- Click selects a cell. Arrow keys move selection. Tab and
Shift-Tab move with row-wrap. Home / End jump within row;
Ctrl/Cmd+Home / End jump to grid corners. Enter, F2, double-
click, or any printable character all enter edit mode. In edit
mode: Enter commits and moves down (Excel convention), Tab
commits and moves right (with row-wrap), Escape cancels and
restores the prior value, blur commits.
- Mount-on-demand cell editor: one <input> at a time is
instantiated inside the selected cell. Survives 1000-row tables
without the focus-ring churn an always-editable design would
hit, and lets Phase 2 swap the input for schema-driven widgets
(number / date / select / etc.) without restructuring.
- Draft buffer at app.state.drafts keyed by row id (the row's
re-edit URL — stable across sort and filter). When a cell
commits with a value different from row.data, the draft entry
is set; render reads from the draft via effectiveCellValue() so
the visible cell content reflects unsaved edits. No-op edits
(commit returns the original value) clear any pending draft.
- Selection survives re-paints. Sort / filter / spec changes
trigger a re-render; the editor's setSelected at end of paint()
clamps to new bounds and rebinds tabindex. The user's cell
doesn't disappear when they sort the column they're editing.
- Numeric coercion fast-path: cells whose column declares
format=number/integer coerce the input string to Number on
commit. Phase 2 will generalize this to schema-driven coercion
for date, boolean, enum, etc.
UX consequence — single-click semantics change:
The pre-existing row-click-navigates-to-form-edit behavior is
gone. Single click now selects a cell (spreadsheet-native). The
"open this row in the form editor" affordance moves to phase 2
(an explicit "Edit…" button or an icon column). The row-click-
navigation tests in tests/tables.spec.js are replaced with seven
new tests covering the editor lifecycle.
What this phase does NOT do (and which phases own it):
- Phase 2: schema-driven editor widgets (right input type per
column). Server-side validation 422 → red-corner marks. Complex
types (object, generic array, oneOf) get an "Edit…" button that
opens the side-panel form-render mode the unified bundle
already ships.
- Phase 3: row-level save on row-blur via PUT + If-Match. Stale-
row badge with "Use mine" / "Reload" on 412. Outbox carries the
offline path transparently via the existing source.js layer.
- Phase 4: copy/paste from Excel/Sheets via TSV parser, spill-
from-anchor or fill-all into a selection range.
- Phase 5: undo (linear command stack, Ctrl+Z, session-local) and
multi-cell ops (range select, bulk delete, Ctrl+D / Ctrl+R fill).
Tests (tests/tables.spec.js, all 15 pass):
- clicking a cell selects it (replaces the old row-click-navigates
test; verifies single-click does NOT navigate)
- arrow keys move cell selection
- Tab and Shift-Tab traverse cells with row-wrap
- Enter enters edit mode; Enter commits and moves down (verifies
draft is applied to visible cell + selection moves)
- Escape cancels edit, restoring prior value (verifies no-op on
draft buffer)
- typing a printable char enters edit and replaces the value
- double-click also enters edit mode
- non-editable rows still get the readonly class (cosmetic guard
for an existing convention; phase 3 will gate write submission)
Files:
- tables/js/editor.js (new) — selection + keyboard handling +
edit-mode lifecycle + draft buffer.
- tables/js/app.js — state.selected / state.editing / state.drafts
fields.
- tables/js/render.js — ARIA roles + editor.attachToCell wiring;
cells render via editor.effectiveCellValue so drafts show.
- tables/js/main.js — paint()-end editor.attachToTable +
setSelected restore.
- tables/css/table.css — selected-cell focus ring (outline,
doesn't shift surrounding cells); cell-input bare-inside-cell
styling.
- tables/build.sh — editor.js in the concat list.
- zddc/internal/handler/tables.html — regenerated bundle.
Bundle size: 117 KB → 124 KB (+7 KB for editor.js + ARIA + draft
machinery). Well within the budget the library survey identified
(Tabulator would have been +100 KB; SlickGrid +34 KB; custom is
+7 KB and we keep the no-third-party-deps invariant).

Two intertwined refactors that share too many files to split cleanly.
Both are described separately below.
PART 1 — in-dir convention for table+form spec files
Old layout had the spec at the parent and rows in a child:
archive/<party>/
mdl.table.yaml spec
mdl.form.yaml row-edit form
mdl/ rows-dir
row-001.yaml ...
URLs were /<dir>/mdl.table.html and /<dir>/mdl.form.html. Copying
mdl/ elsewhere lost the spec and form because they lived next door.
New layout collapses everything into the rows-dir:
archive/<party>/mdl/ self-contained
table.yaml spec
form.yaml row-edit form
row-001.yaml ... rows
URLs become /<dir>/mdl/table.html and /<dir>/mdl/form.html. The
"copying-the-folder-takes-everything" property the user asked for
falls out by construction; the row-edit URL /<dir>/<id>.yaml.html
keeps the same shape (spec is now in the same dir, not the
grandparent).
Server changes:
- internal/handler/tablehandler.go RecognizeTableRequest fires on
/<dir>/table.html when <dir>/table.yaml exists. The .zddc.tables
alias map is gone — pure presence-based discovery now matches
the form system's existing convention. Default-MDL fallback at
archive/<party>/mdl/ stays for the virgin-archive case (the
rows-dir need not exist on disk; the URL renders fully virtually).
- internal/handler/formhandler.go RecognizeFormRequest fires on
/<dir>/form.html and /<dir>/<id>.yaml.html with spec at
<dir>/form.yaml. specEligible accepts on-disk files OR the
default-MDL virtual path so an empty mdl/ dir still surfaces the
add-row form.
- internal/handler/tablehandler.go IsDefaultMdlSpec moves to
serving archive/<party>/mdl/{table,form}.yaml (5 segments after
ZDDC_ROOT). New isAtArchivePartyMdlLevel predicate; new
isAtArchivePartyMdlDir for directory-based recognition. New
IsDefaultMdlSpecAbs accessor for callers that hold an abs path
rather than a URL (formhandler).
- internal/handler/formhandler.go loadFormSpec(fsRoot, path) falls
back to embedded default-MDL bytes when os.ReadFile returns
NotExist AND the path matches the archive-party-mdl shape. Three
call sites updated to pass cfg.Root.
- internal/handler/formhandler.go serveFormCreate writes
submissions to filepath.Dir(req.SpecPath) — the spec, the form,
and rows all live in one directory. The submissionsDir creation
is idempotent (MkdirAll); cascade falls back one level for ACL
evaluation when the dir hasn't been materialized yet.
- internal/handler/tablehandler.go tableRowsRedirect now points at
/<dir>/table.html (was /<dir>.table.html) when the directory
request maps to a recognized table.
- cmd/zddc-server/main.go dispatch synth flips from
urlPath + ".table.html" to urlPath + "/table.html" for the
no-trailing-slash → tables-app routing.
- internal/apps/availability.go DefaultAppAt comment clarified
that the dir at archive/<party>/mdl/ IS the table (not a child).
Client changes:
- tables/js/context.js walkServer fetches <currentdir>/table.yaml
directly — no .zddc walk for table declarations. Rows are every
*.yaml in current dir EXCLUDING table.yaml and form.yaml. The
.zddc fetch-for-aliases is gated on file:// (online mode 404s
on .zddc reads via the dispatcher's reserve guard, so skipping
the request avoids browser console noise).
- tables/js/main.js add-row button links to relative form.html
(same dir).
- tables/js/render.js + filters.js: every column's autofilter is
uniformly a text-contains input, even enum columns — keeps the
filter row visually consistent and doesn't constrain users to
the enum vocabulary.
PART 2 — unified table+form HTML bundle
The form-render and table-render code paths share field schemas,
the cell editor for excel-mode IS a form widget, and the form
system's POST-back / validation already exists. Combining the two
HTMLs eliminates duplicating jsyaml/jsonschema/theme/source-
detection/.zddc-parsing across two single-file tools.
- tables/template.html grows two top-level mode containers:
#table-mode (toolbar + sortable table) and #form-mode (form +
submit button). Both hidden at parse time; the dispatcher
unhides one. The shared #form-context placeholder was added
here so the server's existing injectFormContext target
resolves.
- tables/js/mode.js (new) sets window.zddcMode synchronously
based on URL pattern: /form.html or /<id>.yaml.html → form,
/table.html → table, else inline-context fallback for
file:// (whichever context blob is non-empty wins). Unhides
the matching container at DOMContentLoaded.
- tables/js/main.js init() and form/js/main.js boot() each guard
early when mode isn't theirs. Both apps live on different
globals (window.tablesApp vs window.formApp) so module
registration doesn't collide.
- form/js/main.js title write falls back from #form-title to
#table-title (the unified bundle's shared header element)
when the dedicated id isn't present.
- tables/build.sh concatenates form modules (widgets, render,
object, array, errors, post, serialize, util) and form CSS.
No new external deps. Bundle grows from ~95KB to ~120KB.
- internal/handler/formhandler.go drops the //go:embed form.html
directive; serveFormRender now writes embeddedTablesHTML via
a small formRenderHTML() accessor (var declared in
tablehandler.go, same package). The embedded form.html file
is removed.
- build script: cp form/dist/form.html → internal/handler/form.html
step is gone (file no longer exists in the source tree). cp
tables/dist/tables.html → internal/handler/tables.html now
runs unconditionally rather than only on beta/stable cuts —
the renderer is a fixed binary component and dev iteration
needs the embedded copy refreshed every build. Channel-cascaded
apps (internal/apps/embedded/) stay channel-gated as before.
- form/dist/form.html still builds for standalone offline-only
use (downloadable from /releases/), but no longer goes into
the binary.
Tests:
- internal/handler/tablehandler_test.go and formhandler_test.go
rewritten for the in-dir layout. New test
TestRecognizeFormRequest_DefaultMdlAtArchiveParty covers
empty-form, create POST, re-edit row, and the negative cases
(Working/, non-mdl name) where the fallback must NOT fire.
- internal/handler/directory_test.go updated for the new
/<dir>/table.html redirect target.
- cmd/zddc-server/main_test.go TestDispatchSlashRouting Location
expectation updated.
- tests/form-safety.spec.js loads tables/dist/tables.html
(named form.html in the temp dir to trigger form-mode in the
dispatcher) so it tests the same bytes the server returns.
Title-element selector switches to #table-title.
- tests/tables.spec.js updates the status-filter test for the
uniform text-input filter.
Docs:
- AGENTS.md form-data system rewrites the URL conventions and
storage layout for in-dir; gains a Tables system section
parallel to forms describing the self-contained-directory
property; subfolder rules ("one table per folder by
construction; subfolders allowed and silently ignored as rows
— legitimate uses: nested sub-tables, per-row attachments,
drafts, future history sidecars") so we don't re-derive this.
Not included (deferred):
- ACL gating on cell-level writes — not relevant until Phase 3.
- Editable cells UI — separate commit (Phase 1).

Tables is the eighth HTML tool: a read-only tabular view over a
directory of YAML files declared via `tables:` in `.zddc`. Anchor use
case is the Master Deliverables List, where each row is one
`<tracking>.yaml` under `Archive/<Party>/MDL/`. Rows click through to
the existing form renderer for editing.
Schema (zddc/internal/zddc/file.go)
- New `Tables map[string]string` on ZddcFile. Map key becomes the URL
stem (`tables[MDL]` → `<dir>/MDL.table.html`); the value is a path
relative to the .zddc pointing at a `*.table.yaml` spec describing
columns + the rows directory. No upward cascade in v1 — each
directory hosting a table declares it directly.
Server handler (zddc/internal/handler/tablehandler.go)
- `RecognizeTableRequest` matches GET `/<dir>/<name>.table.html`
against the cascade's `tables:` declarations. Dispatch routes
table requests before the form-system intercept.
- `ServeTable` ACL-gates with `policy.ActionRead` and serves the
embedded `tables.html` template; client walks the directory itself
via the listing JSON or FS Access API.
- tables.html embedded via //go:embed — same pattern as form.html.
Frontend (tables/)
- Vanilla JS: app/context/util/filters/sort/render/main modules.
- Reads spec + row YAML files via window.zddc.source (HTTP polyfill
or local FS handle); js-yaml 4.1.0 vendored in shared/vendor for
client-side parsing.
- Sample fixtures under tables/sample/ for local testing.
Build + CI
- Lockstep build registers tables alongside the other 7 tools (HTML
output, embed mirror, versions.txt, release-output, tags).
- Playwright project added; `npx playwright test --project=tables`
is part of `npm test`.
Drive-by: rename mdedit Playwright selectors `#select-directory` →
`#addDirectoryBtn` to fix three pre-existing failing tests.
Drive-by: ignore locally-built `zddc/zddc-server` binary so it doesn't
get accidentally staged.
