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.
