verify-shell-scroll.mjs was written and negative-tested, then left with no
package.json entry and no importer, so nothing could ever run it again. It
also defaulted to localhost:8899 -- an ad-hoc port from an earlier session --
so it failed with ERR_CONNECTION_REFUSED for anyone else and read as a broken
gate rather than a missing server. Now check:shell-scroll, defaulting to
BASE_URL or 127.0.0.1:4173 like every other browser gate, and listed in
verify-browser-all's GATES array.
check:no-orphan-gates fails any gate-shaped file in internal/ that nothing can
invoke. The repo carded this once already; it recurs because writing a gate
and registering one are separate acts and only the first feels like work.
Not every unreferenced file is a lost gate, so the rule is not "everything
must be wired": theme-flash-probe is a dated diagnostic for two fixed bugs,
worth keeping as a reproduction recipe. It now carries an @one-shot tag saying
so, which makes the author state which kind of thing they wrote.
Two self-referential defects in the first version of that gate, both from
reading evidence out of documentation:
- it cited theme-flash-probe.mjs in its own header as an example, then grepped
for importers, found itself, and declared the orphan reachable. The gate
written to catch orphans made an orphan pass by mentioning it. A gate must
never be its own witness, so it now excludes its own file.
- it matched @one-shot anywhere in prose, including its own paragraph
explaining the tag, and reported "1 tagged" when nothing had been tagged.
The tag must now be a marker at line start.
Negative-tested: removing check:shell-scroll from package.json fails by name.
The scroll fix itself is NOT done. contain:layout and .vtl-host overflow-y are
confirmed in the built bundle, and a real wheel gesture still moves the grid
0px with 2586px mounted and unreachable. The gate is what caught that; the
diff looked correct.
