From the fence's kept frames in 22 minutes of play: - A component field that is a record or a list of records was `value_put(o, k, view_val_T(x))`, a whole new tree every frame (HudPrompt's notifications). view_fill.ludic generates view_set_T / view_set_list_T / view_fill_T that fill the object and list under the key in place. - value_list_fit dropped the items it cut off and value_item made new ones as the list grew back, a Value per item per regrowth (value_item / value_set_strs); the cut-off items are now the list's spares (Val.spare), and an item of another kind is turned rather than replaced. - ludic.ui: a scroll box's "scroll" and a slider's "change" fired a fresh Value.float a frame (sc_walk, scroll.ludic:36); ui_fire_float takes one from a ring kept with the state (fired.ludic). ui_object_fit_into is exported, for a draw that keeps its list. - Json.read_file(path): read, parsed, and the file's text given back - Json.parse(Fs.read_text()) kept the whole file on every read (Maroon Lake's settings peeks). Golden value_list_regrow: a list alternating 6 and 2 items every frame keeps nothing (the toolchain before this fails it: +128 B new Val from value_item). Game compiles; ludic.i18n/settings/hints/ base tests pass (ludic.ui has none); arena and fence goldens unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
