Both came from the Driver's console in the gallery's Simple Research tab, and both come from one
gap: where a line SITS in a setup block is not WHEN it runs.
research-map.vue — "Cannot access '_lastFitKey' before initialization", thrown during setup, which
left the map blank. The externalFilters watcher is immediate:true, so it runs while setup is still
on the stack and calls applyFitSlugs() 350 lines below it. The CALL resolved, because a function
declaration is hoisted; its constants are not, so the first read hit their temporal dead zone. A
hoisted function promises that its NAME resolves early, not that its BODY can run early, and that
asymmetry is invisible from both ends: the watcher looks like it only touches the store, and the
constants look like they sit right beside the function that reads them. They and the guard now sit
above the watcher, with a note saying why they cannot live next to applyFitSlugs().
DashboardMapPanel.vue — "onBeforeUnmount is called when there is no active component instance".
A lifecycle registrar closes over Vue's current instance, which exists only while setup is on the
stack, so a hook registered after "await initializeMap()" is silently dropped: a ResizeObserver on
document.body plus a window resize listener outlived the component. Nothing threw and the feature
worked, so it showed only as a studio that slowed down the more tabs a reader had visited. The fix
is not to move the line — the code that creates those handles is past the await either way. The
handles move to setup scope and are torn down in the hook this file already registers correctly,
which is the pattern it was using three lines away for containerRO and attribRO.
research-map.vue held a second copy of the same leak, its scroll-zoom resync listener. The new
gate found that one; reading the file had not.
check:setup-order covers both classes. Its own false positives are the instructive part: 6 hits
down to 1 over three rounds, and every one it dropped was prose or shadowing read as code — an
onBeforeUnmount inside a console.error STRING, the word "table" inside a new Error(...) template
literal in four files, and a destructured byCountry shadowing a computed 220 lines away. So it
blanks comments, string text and template text while keeping ${...}, which is code, and subtracts
every name a span declares for itself. It self-tests on both shipped defects, both fixes and all
three decoys, and exits 3 if an arm goes blind rather than passing quietly.
Source only. doxa-research-map, research-dashboard and dashboard-plus-grid need a rebuild.
