Dispatch work item (5) asked for useTextHighlight in library/. RULE 2 wants a named
SECOND consumer before anything moves there, and it exists: regions-dashboard's
UupgsList and people-groups-grid both consume the same Fuse-compatible shim, both
read match.indices, both wrap hits in <span class="search-highlight">, and both
append the tail only on the last range. Line for line the same construction, apart
from variable names.
So library/composables/useTextHighlight.js exports highlightRanges(value, indices),
and UupgsList calls it. Its local escapeHtml goes too: every caller was inside the
highlight body that moved.
★ ESCAPING NOW COMES FROM library/utils/html.js, AND THAT IS A CHANGE FOR BOTH
CALLERS, stated rather than smuggled. Three implementations existed and differed:
library/utils/html.js escapes & < > " ' AND backtick; returns '' for null
UupgsList no backtick; guarded null via String(v ?? '')
people-groups-grid no backtick; NO NULL GUARD — s.replace(null) THROWS
Both deltas move in the safe direction — one more character escaped, one crash
removed — and neither changes the output of any value that renders today. The gate
pins both, with controls proving each delta is a real difference rather than a
no-op: the old copy really does leave a backtick unescaped, and their escaper
really does throw on null.
people-groups-grid is NOT migrated here: it is another owner's file, so it is
handed over as source. The gate asserts it still builds its own highlighter, so
this check states the truth rather than implying the job is finished.
check:text-highlight is registered (script line, gates:post token, hand-inserted)
and negative-tested: an implementation that escaped nothing fails it, and the
output is asserted to depend on the indices.
