Read the recorded behavior analysisA React PureComponent (render returns null) mounted at app shell level. On mount it registers window resize (handleResize and a 300 ms debounced copy), an orientationchange handler that re-dispatches a resize after 300 ms, and a gesturestart preventDefault. It calls handleResize immediately, sets history.scrollRestoration to manual, and adds body classes from browser info. handleResize writes --vh from innerHeight on the next animation frame and dispatches onSwitchViewport with the viewport name from two matchMedia queries when the name differs from this.viewport. Unmount removes only the two resize listeners.

Targets: html, body
- componentDidMount adds window resize listeners for handleResize and the 300 ms debounced copy, and an orientationchange listener that re-dispatches a resize event after 300 ms.
- componentDidMount adds a document gesturestart listener that calls preventDefault.
- componentDidMount sets history.scrollRestoration to manual when the property exists.
- The viewport name comes from two matchMedia queries v.d and v.g. If the first matches, v.c is returned; otherwise if the second matches, v.f; otherwise v.a. The constant values are not resolved in this pass.
- handleResize dispatches onSwitchViewport(e) only when the detected viewport name differs from this.viewport. In the visible source, this.viewport is initialized to an empty string and not reassigned in this function, so the guard may pass on every call.
- A second resize listener uses debounceResize, which wraps handleResize with a 300 ms debounce.
- componentWillUnmount removes only the resize and debounced resize listeners. The orientationchange and gesturestart listeners are not removed in this component.

- https://heycusp.com/assets/main.43cc6440.js: Wakaru unavailable: time limit exceeded
- Feature viewport-shell-resize is saved, but its planning attempts are exhausted (5/5). Its probes are unverified: no current assertion has a validated live reference, so no measured pass is claimed.
- Only entry-vh-desktop, resize-reversal-vh-desktop and resize-vh-mobile-size were planned, all on desktop. Tablet, mobile and reduced-motion histories were not measured.
- Facts mount-listeners, viewport-detect, viewport-dispatch-guard, debounce-copy, unmount-cleanup and connected-dispatch have no supported DOM measurement linked. gesture-block and scroll-restoration are not observable through the supported DOM metrics.
- Flow 3 (orientationchange to resize after 300 ms), Flow 5 (handleResize to onSwitchViewport) and Flow 6 (componentWillUnmount to removeEventListener resize) have no measured linked input.
- Citations for module 1d91ce48ee4c303e22010b990902b919 line 28 lack a parsed node and rely on literal line quotes. The module exceeds the 2 MB structural parse limit.
- Unresolved: media-query constants v.a, v.c, v.d, v.f, v.g; debounce helpers N() and $(); whether this.viewport is reassigned elsewhere; the onSwitchViewport (K.f) consumers and their effects; any reduced-motion handling outside this component.
- Source shows orientationchange and gesturestart listeners are not removed on unmount. This is recorded as source-visible only, with no runtime confirmation.
- Source feature viewport-shell-resize has an incomplete measurement plan; its planning and escalation attempts are exhausted; mapped source facts do not establish execution or verification.
- New source or interaction evidence awaits analyst review; the source analysis pass allowance is exhausted.
- 98 runtime source locations exceed the 32-location module-prioritization allowance; inspect_runtime_sources can investigate them explicitly.
- 1 modules exceed lightweight DOM-ranking limits; they remain available for explicit source inspection.
- 1 source modules could not be fully indexed for behavior discovery; use literal source inspection for their remaining code.
- 12 captured modules have not been selected for behavior indexing; DOM text and observed runtime locations prioritize leads, not exhaustive coverage.
- App shell viewport, --vh, body classes and resize dispatch: 39 behavior verification gaps remain.
- 20 source requirements have no current implementation mapping.
- 3 planned source assertions remain unverified.
- Global click listener requires source-directed or observed event targets
- Runtime attribution limited to 100 records per phase and 2400 per visit
- Repeated callback executions retain counts and four samples per registration/phase
- Function attribution limit reached (300)
