DeepSeek ships a card's photo area as an UNNAMED rectangle sized
fill_container x fill_container - no keyword, no number - so every
name-and-size heuristic missed it and the whole page came out as grey
boxes. What a slot IS is a question about geometry, so the pass now asks
the real layout: an empty painted box that RESOLVES to picture size, in a
card that has words in it, is a photo slot. The words come from the card's
own subtree (a title nested in an info frame still names the picture), the
nearest ancestor that names the subject wins over them, and a cousin card
is never consulted.
A batch died on "header is not defined": the model referenced a const from
the PREVIOUS batch's script, but every script runs in a fresh sandbox. The
error now says so and points at the fix (reference the node by its id
string), and the program-DSL contract states it up front.
The transcript's markdown also painted every span at the wrap ESTIMATE
(6.6px per unit) while skia draws real glyph advances, so each span after
the first sat at a slightly wrong x - code chips drifted off their words
and a sentence read as fragments. Paint now advances by the measured width;
wrapping stays estimate-based, since it must stay backend-free.
MiniMax-M3 shipped a whole travel page as grey boxes: it builds every card
around a rectangle named "img" (or a "ph" rectangle inside an "img"
wrapper), and neither word was in the image-slot keyword table, so the
enrichment pass never saw a single slot. Both are slots now - and because
such a name carries no subject of its own, the query falls through to the
card that names the picture ("Santorini").
The rim was a polygon STROKE, and the trait's fallback draws a polygon
stroke as one capped line per edge - so every vertex of the densely
sampled arc notched and the rim's width visibly wobbled. Two fixes: the
native backend gains a real single-path, round-joined, antialiased
polygon stroke (every caller benefits), and the cursor's rim is now
FILLED geometry - the silhouette outset by an exact 1.6px, painted white,
then covered by the body. The halo layers clear the rim so the outline
reads crisp against both light and dark designs.
The search bar came out grey with an invisible filter icon. Two causes,
both mine to fix.
The model painted the bar $--accent believing it was the brand colour -
in the shadcn vocabulary --accent is a quiet NEUTRAL surface and the brand
colour is --primary. The design-system teaching I added told the model to
use tokens but never said what they MEAN; it now carries the semantics
table, with the neutral-vs-brand trap called out.
The filter glyph was painted $--white - a token in no table. An unresolvable
reference silently rendered as an invisible glyph. A broken reference is now
repaired against the surface it sits on: a glyph on a soft tint takes that
tint's colour at full strength, a glyph on a token surface takes that token's
-foreground partner, and a container's unknown fill is dropped rather than
guessed.
Watching a run frame by frame: a real Bali temple photo landed, then
halfway through it turned into a plain blue sky. The model had rebuilt
the section (fresh node ids), the same query searched again, and the
session-wide dedup - there to stop two cards sharing one picture - now
skipped the very photo that query had already chosen, leaving the junk
below it. A query this session already answered now resolves from a memo:
no network call, and no downgrade. Dedup still guards different subjects
from sharing a photo.
A 16-page document whose first page was a blank cover opened onto empty
canvas ("content bbox None") and read as a load failure - the design was
on page 2. With no editor metadata to restore, the file now lands on the
first page that has content; a file that is empty everywhere still opens
on page 1.
The model writes markdown - bold labels, hex codes in backticks, bulleted
build summaries - and the panel flattened all of it: markers stripped,
bullets faked by gluing a dot into the string, code indistinguishable
from prose. The transcript now renders a deliberate subset (**strong**,
`code`, and - bullets) as real typography: labels in bold on the
foreground tone, body in the muted one, code in a tinted chip, bullets
with a hanging indent so wrapped lines align under the text. Unclosed
markers stay literal - a syntax that silently eats characters is worse
than none.
The engine's flex default is a ROW, so a section frame that never declared
layout laid its title beside its card rail and pushed the cards off the
screen (measured: every section in a DS run). An omission is not a request
for a row - a container with flow children and no layout now stacks, and
the program-DSL contract says to declare it.
A batch died on "provide only one of script, operations, or nodes_json"
because the model sent the unused slots along as empty placeholders. An
empty value ("", [], {}, null) is not a choice of input: the batch now
runs whichever slot the caller actually filled, while a lone empty
program still reports rather than reading as applied.
Three defects from one document, all the same failure: the design was
authored right next to where it belongs, and nothing put it back.
- A photo parented to the CARD instead of the empty slot inside its image
band painted below the price row while the band showed a lone badge on
white. It now moves into the slot that was waiting for it (only when
there is exactly one candidate - ambiguity stays the model's call).
- The band takes the height of a photo nested one level down, not just a
direct child, so a 56px band around a 160x180 photo box stops cropping
every card to a sliver of sky.
- A painted row of fixed-size controls given fill_container width stretched
across the header and painted as one capsule around the bell and the
avatar; a cluster of fixed controls hugs them. Flex nav tabs and unpainted
rows are untouched.
MoveNode/CopyNode also stop refusing a childless container as a target: a
container that has never held a child still has room for one, which is
exactly what an empty media slot is.
Both of today's image repairs trusted an authored fixed size as the
design's intent. A weak model routinely drops a 400x300 plate into a
390px phone card and CROPS it - which looks right - so the rail repair
widened every card to 400 (one card ate the screen, the rest clipped
away) and the band repair grew every photo band to 300 (a wall of empty
space under each deal). Both now demand that the number be plausible for
the slot it is in: a card is starved only when it is genuinely unusable
and its demand still leaves the rail scrollable, and a band only takes a
photo's height when the result is not taller than the band is wide.
Oversized plates go back to the fixer that shrinks them.
Suppressing the queue left holes in the middle of the skeleton while the
model was working the top - the skeleton-first effect is wanted, only one
shell may look ACTIVE. The on-deck shell (first empty in fill order)
keeps the radar sweep; every queued shell now paints a still wireframe -
outline plus a whisper of wash, no band - so the whole page reads as
planned-but-unwritten instead of half missing, and nothing downstream
pretends to be under the cursor.
A chip sat 6px under the paragraph it followed but 14px above the next
one, so it read as belonging to the story below it rather than the one
it came from; both sides now take the same breathing room. The expander
also becomes the reference's stacked up/down caret pair instead of a
navigational chevron-right.
Five destination cards rendered as five identical blue bands. The photos
were fine and all different - the cards were the problem. Each card's
image slot carried TWO images (an absolutely-positioned image-filled
plate AND the real image node) inside a band authored 56px tall against
a 130px photo, so all that survived the clip was each photo's sky.
The duplicate plate is dropped (the image node wins - it is what the
image pipeline fills and re-searches), the band grows to the photo's own
declared height when it would hide more than half of it, and the starved
rail-card repair now reads fixed-width DESCENDANTS and assigns the
demand as a definite width: an out-of-flow photo plate contributes
nothing to a hug, so fit_content re-starved the very cards it was meant
to rescue (126px against a 200px plate). Replaying the measured document
through the repair loop: 4 geometry diagnostics to 0, cards 79px to
200px.
Three defects from one live run. The tool chips were 48px slabs with a
right-flushed status glyph; the reference reads as a 28px row with the
check inline after the verb. The cursor halo was three concentric
STROKES, whose joins banded into a dirty grey ring on the pencil's
corners - it is now a feathered stack of filled expansions (no joins,
no banding) that doubles as the contact shadow. And the work-order gate
was per-container, so a root's trailing bottom-nav shell lit up and took
the cursor while the model was still filling the header nested inside
the content wrapper; fill order is document order, so the deck is now
global to the generating root.
Design-loop turns used to render as one collapsed 'N tool calls' row
above a monolithic prose wall. The transcript now splits the narration
at each call's stamped content offset and lays prose paragraphs and
headerless verb-chip panels in chronological order, so the story reads
top-to-bottom the way it happened; chips stay visible (nothing folded
away) and each card toggles its own expand override via the original
call index. Plain chat turns keep the grouped panel.
