Of the 13 train cases the stopped run's reference missed, 11 need sizes the engine does not compute: nine use min-content, max-content or fit-content on the box or its parent, and two (block-aspect-ratio-015 and -043) need the automatic minimum width, which grows a ratio-derived width to a child's min-content width. The other two (margin collapsing through a ratio box, a percentage height resolved against a ratio-derived height) are in scope and belong to the engine wiring, not the function. The feature file denies the keywords by pattern, like every other layout mode the engine lacks, and names the two pages under a new `exclude` map (page name to reason) that feature-pages.mjs rejects as `excluded:<reason>` before the deny patterns and refuses without a reason. 289 pages now give 42 selected (35 train, 7 held out), 33 and 7 measured cases; the prompt built from the 33 is 52,705 characters.
