tables/js/save.js: on 200/201, parse the YAML body the server now
echoes back (it carries the just-stamped audit fields) and replace
row.data with it. The previous local-merge code falsified the table
view — server stamping changes bytes the client doesn't predict
(revision, created_by, previous_sha), and the merge would have shown
stale values until a fresh GET. Falls back to local merge when the
response has no body (non-record write or older server).
form/js/widgets.js:
- honor schema.readOnly (alongside the existing ui:readonly UI
override) so cascade-locked + audit fields render as disabled
- read x-labels for enums and render "<code> — <label>" in both
<select> and radio variants (server-injected from
field_codes:codes for human-readable dropdowns)
- propagate schema.pattern to <input pattern> as a UX hint
(authoritative validation runs server-side via WriteWithHistory)

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.

The TODO at save.js's unload handler was "switch to keepalive on save
for the unload path." flushAllDrafts() kicks off saveRow() per dirty
row when the page is being navigated away from, but those fetches were
not flagged keepalive — modern browsers can cancel them mid-flight as
the page unloads, dropping the user's last typing.
saveRow() now accepts an opts.keepalive flag that is passed through to
fetch(). flushAllDrafts() passes {keepalive: true} so the unload path
gets the keepalive guarantee. Normal saves are unaffected (keepalive
imposes a 64 KB body cap per the Fetch spec — only worth that trade
on the unload path).
Also refreshes the embedded zddc/internal/handler/tables.html bytes via
./build, which folds in this change plus the form welcome-state CSS
from c585112.

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.
