upg-neighbor/flower-mesh is a preset of the upg-neighbor element that opens on
its Flower Mesh lens, which is SVG and has no GL map. The leaf is still a map
element: the view-switcher reaches Send Map and the other GL lenses, so it must
keep isMap (engine peer, token ladder). Marking it isMap:false would break those
lenses. check:leaf-engine-per-provider judged it as a drawing map and failed it
on both engines ("drew: none"), before and after the auto engine alike.
- upg-neighbor.instances.json: the flower-mesh preset says "opensOnMap": false.
- generate-tree.mjs: an instance's manifest entry carries opensOnMap:false when
it is set (absent otherwise, so every other entry is byte-identical).
- check-leaf-engine-per-provider.mjs: such a leaf is not judged as a drawing
map. Its Mapbox-request count under ?provider=maplibre is still measured.
Headless: after bun run tree, the manifest marks only
upg-neighbor/upg-neighbor/flower-mesh with opensOnMap:false. The gate's leaf
selection, replayed over it, judges 28 of 56 leaves as drawing maps, with
flower-mesh excluded and its five siblings unchanged. No browser run.
A generated map leaf chose its engine at BUILD time and hard-linked it in <head>: mapbox-gl.css,
the geocoder css, mapbox-gl.js and the geocoder js from api.mapbox.com. The provider is chosen at
RUNTIME (profile-config.provider → ?provider= → window.MAP_PROVIDER), so a partner embedding a leaf
with ?provider=maplibre still had every visitor's browser make 4 requests to Mapbox.
- generate-tree: no static engine tags on map leaves; the element's own runtime loaders
(ensureEngineScript / ensureEngineCSS, the geocoder's on-demand loader) load exactly the engine
asked for, the path composite leaves already ran on. The forge page drops its api.mapbox.com
preconnect. A leaf opened with provider=maplibre (same ladder as resolveMapProvider) is token-free,
so the public copy no longer asks a MapLibre visitor to paste a Mapbox token.
- check:leaf-engine-per-provider (new, browser): every leaf at ?provider=maplibre makes 0 requests
to *.mapbox.com and still draws; at its default every map leaf draws with the engine it drew with
before (--baseline <tree> compares against another tree).
- check:dashboard-geocoder-provider is wired into gates:post alongside it; it had been held out
because this generator's tags made it red.
- verify-map-paint: optional GATE_VIEWPORT for a phone pass.
Measured before this landing (browser runs made before the headless rule): leaf-engine vs main's
tree PASS, 56 leaves, 0 Mapbox requests under MapLibre, same default engine. Pins, region popup,
PPLR search and key-cities PASS on both engines with 0 Mapbox requests under MapLibre. RTL shaping
PASS on both engines wherever RTL labels rendered. Paint under MapLibre: the same 4 leaves fail as
on main (country-posters-mfe, upg-100-mfe, regions-mfe, flower-mesh). Pre-existing, not caused here.
Poster "Render" is missing on country-posters and doxa-research-map under BOTH engines. Pre-existing
on main, read from source: countries-map.vue renders <PosterDialog v-if="showPoster"> without
v-model or getMap, and PosterDialog shows only when modelValue is true.
Headless, on this commit's regenerated tree: 57 leaves, 0 carry api.mapbox.com engine tags (main's
doxa-simple-map leaf carried 5), 56 carry the runtime provider check, check:sri PASS.
