* fix(url-sync): don't overwrite URL position params on initial load Race condition: setupUrlStateSync() called debouncedUrlSync() immediately, but applyInitialUrlState() had already started an async flyTo via setCenter(). At ~250ms the debounce fired while the flyTo was still running, reading the map's default center (lat=20, lon=0, zoom=1) and writing it back over the URL-specified params. Fix: skip the immediate debouncedUrlSync() call when URL position params are present. onStateChanged fires on moveend (after flyTo completes) and handles the first URL write at that point with the correct position. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(url-sync): pass URL zoom to setView and always apply URL lat/lon When the URL contains ?view=global&zoom=1.00, setView was called without a zoom override, so flyTo animated to the preset zoom (1.5) instead. The subsequent moveend/onStateChange cycle then wrote zoom=1.50 back to the URL, overwriting the correct zoom=1.00. Pass the URL zoom as the second argument to setView so flyTo targets the correct zoom level. Also remove the effectiveZoom > 2 guard from the lat/lon branch so URL lat/lon is always honoured regardless of zoom level. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(url-sync): implement setView(view, zoom?) across all map implementations DeckGLMap, GlobeMap, Map, and MapContainer setView() only accepted a single view argument — the zoom passed from panel-layout was silently ignored, so ?view=X&zoom=Y still wrote the preset zoom back to the URL after moveend. - DeckGLMap: pass zoom ?? preset.zoom into flyTo - GlobeMap: apply same deck.gl→altitude mapping as setCenter when zoom provided - Map (SVG): use zoom ?? settings.zoom for the SVG map zoom state - MapContainer: forward the optional zoom to all underlying implementations * fix(url-sync): forward zoom on SVG path + tighten urlHasAsyncFlyTo guard P1: MapContainer was forwarding zoom to DeckGL/Globe but not to the SVG fallback renderer — ?view=X&zoom=Y was still loading at preset zoom on mobile/WebGL-fallback. P2: urlHasPosition fired on any single URL param including lone ?lat or ?lon. applyInitialUrlState only calls setCenter when both are present, so malformed links like ?lat=41 skipped canonicalization and left stale params in the URL until the user moved the map. Fix: rename to urlHasAsyncFlyTo and only suppress the initial debounced sync when applyInitialUrlState will actually trigger an async operation: - view is set (setView → flyTo) - both lat AND lon are set (setCenter → flyTo) - zoom is set (setZoom → animated zoom) * fix(url-sync): remove view from urlHasAsyncFlyTo suppression guard view was included in the suppression condition but this breaks two renderer paths: - SVG/Map: setView() is synchronous and fires emitStateChange before the URL-sync listener is installed (App.ts wires listeners after applyInitialUrlState runs). No async callback ever fires to drive the URL write when suppressed. - GlobeMap: onStateChanged() is a no-op stub — suppressing the initial debounce leaves /?view=X deep links without any URL sync on the globe renderer. view state is written synchronously at the top of every setView() implementation (this.state.view = view), so the 250ms debounced read is always correct regardless of renderer. Remove view from the guard. Only suppress for the two cases where an in-flight flyTo makes getCenter() return stale intermediate coordinates: (a) lat+lon pair present → setCenter() flyTo (b) zoom-only without a view preset → setZoom() animated zoom * fix(url-sync): eagerly cache target center+zoom in DeckGLMap.setView DeckGLMap.setView() started a flyTo without updating this.state.zoom or this.pendingCenter. The 250ms URL debounce would then read: - state.zoom → old cached value (wrong zoom written to URL) - getCenter() → maplibreMap.getCenter() mid-animation (intermediate coords written to URL, e.g. lat=22.1 instead of 25.0) Fix: at the top of setView(), before flyTo starts: - Set this.state.zoom = zoom ?? preset.zoom (zoom correct immediately) - Set this.pendingCenter = preset lat/lon (center correct immediately) - getCenter() returns pendingCenter when set, falls through to live maplibre coords after moveend clears it This ensures any URL sync that fires during the flyTo animation (whether the initial 250ms debounce or an onStateChanged triggered by the sync setView call itself) reads the correct destination values. * test(url-sync): regression coverage for initial URL-sync suppression + DeckGLMap.pendingCenter 20 tests across three suites: - urlHasAsyncFlyTo guard: 10 cases covering cold load, view-only, partial lat/lon, full lat+lon, bare zoom, view+zoom, and the setCenter override path. - DeckGLMap.pendingCenter: 8 cases verifying eager center/zoom cache on setView, override zoom, consecutive calls, and moveend clearing the cache. - Integration regression: view=mena path confirms suppression is skipped and pendingCenter holds correct preset coords for the URL builder. --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> Co-authored-by: Elie Habib <elie.habib@gmail.com>
