Every card and DOM panel was added with options.serialize = false, which
only keeps a widget out of the queued prompt. The frontend saves each
widget whose own serialize is not false and hands saved values back by
position, so each card and panel saved an empty value of its own after the
node's real values, and an input appended to the node later opened holding
it (Stitch Inpaint's seam, Crop For Inpaint's keep_inside). Every DOM widget
now also sets widget.serialize = false, as the frontend's own previews do,
so new saves carry only real values.
Older saves still end in those empty values, and loading them now skips
the cards and panels. On every node that saves by position they come after
all real values (Save Image's card sits mid-list, but Save Image saves by
name), so nothing moves. On frontend 1.53.6 the examples (the 21 from
before the trim and the 7 now) and 14 older saved workflows queue
byte-identical prompts before and after, keep every value, and save and
reopen cleanly.
An input appended later still needs a fallback for those older saves.
tests/saved_widget_values.test.mjs checks that every DOM widget sets the
flag, that the examples keep their values with the panels skipped, and that
each input appended to a node whose older saves end in an empty value is
declared and, as a widget input, has a card resetUnknown fallback that
fires. tests/test_card_fallbacks.py (ComfyUI's Python) checks each fallback
is the input's own default. AGENTS.md states the rule.
