Wheel, touch, pointer, scroll, preventDefault, touch-action, duplicate registration, cleanup, and bounded synchronous-work evidence remain explicit without fake browser measurement. This is the real published Genesis interface—not a stock image.

Passive Event Listener & Scroll Blocking Auditor
Audit supplied wheel, touch, pointer, and scroll-listener evidence for passive-option conflicts, unnecessary blocking, cancellation boundaries, duplicate registration, cleanup gaps, and synchronous main-thread work.
An original zero-dependency static evidence auditor for event-listener scroll behavior. It normalizes listener options, distinguishes observation from declared preventDefault cancellation, evaluates caller-supplied touch-action and work evidence, detects duplicate registrations and cleanup mismatches, returns deeply frozen severity summaries, and creates non-mutating remediation plans without intercepting events or changing application behavior.
Genesis checks the site, shows what looks wrong, and helps you understand what needs attention.

Read license termsWhat it helps you do
- Passive and preventDefault contradictions separated from verified cancellation needs
- Touch-action, duplicate registration, cleanup, work-budget, and synchronous-operation findings
- Frozen deterministic reports and non-mutating plans with no browser interception or source mutation
What this specific product actually does
Every Genesis listing has its own capabilities, workflow, automation status, limits, and proof standard—without generic promises copied from another product.
Inside Passive Event Listener & Scroll Blocking Auditor
- 01Audits wheel, mousewheel, touchstart, touchmove, pointerdown, pointermove, and scroll-adjacent evidence.
- 02Distinguishes omitted, boolean-capture, passive, non-passive, once, and AbortSignal-style registration evidence.
- 03Flags passive cancellation contradictions, unnecessary non-passive listeners, and cancellation paths without a declared verified need.
- 04Checks caller-supplied touch-action boundaries and identifies ineffective preventDefault behavior on the non-cancelable scroll event.
- 05Evaluates configurable supplied work budgets plus sync XHR, forced-layout, heavy-loop, broad-query, style-write, and serialization signals.
- 06Detects duplicate registrations and capture-mismatched cleanup, then returns deterministic frozen reports and non-mutating remediation plans.
Scroll-listener evidence without fake browser certainty.
The auditor analyzes supplied facts only; the host owns source and runtime collection, real profiling, gesture intent, implementation, accessibility and browser testing, publication, monitoring, and rollback.
This product does not modify a customer website.
Who this is built for
- 01Frontend teams reviewing scroll responsiveness before changing listener options
- 02WordPress, Shopify, Webflow, HTML/CSS, and React projects documenting passive-listener evidence in CI
- 03Performance and accessibility reviews that need stable rule IDs without pretending static evidence is browser profiling
How you receive it
GCD-WEB-293
Verified ZIP · 15 files · JavaScript + TypeScript declarations + 135 tests + README + START-HERE
All Platforms, WordPress, HTML / CSS, Shopify, Webflow, React / Next.js
Free
This listing is a downloadable Genesis code package. The ZIP includes reusable code and START-HERE directions.
Three steps for this product
- 01
Collect truthful listener evidence
Record the target, event type, stable handler ID, exact options, cancellation behavior, cleanup evidence, touch-action policy, and profiler-backed work facts when available.
- 02
Audit before rewriting
Resolve contradictions and review each recommendation against intended gesture behavior; never apply passive:true automatically to a legitimate cancellation path.
- 03
Test and publish separately
Verify wheel, touch, pointer, keyboard, zoom, nested scrolling, cleanup, representative devices, target browsers, monitoring, and rollback through the normal release workflow.
Before & After Repair Report
Passive Event Listener & Scroll Blocking Auditor · GCD-WEB-293
Report format preview. Scores and status values populate only from measurements produced by an actual run. Genesis does not invent improvements.
What Genesis Code Doctor fixed
- Only verified changes appear here.
- Each repair can show affected files, routes, checks, or rules.
- Regression checks are recorded separately from the repair itself.
Still needs attention
- Unresolved, blocked, unavailable, or not-tested items remain visible.
- Evidence links can explain why an item passed, failed, or needs review.
- Follow-up verification can be run after implementation.
Know the fit, evidence, and handoff before a repair is used.
These controls turn a code product into a traceable repair workflow. They do not claim compatibility or success that has not been verified.
Declared support is available
Declared platforms: All Platforms, WordPress, HTML / CSS, Shopify, Webflow, React / Next.js
Exact compatibility still depends on the customer's framework version, dependencies, hosting, custom code, and current site state.
Lifecycle protection is part of the product standard.
- Compatibility is reviewed before release.
- Regression and rollback requirements stay explicit.
- Follow-up verification can be run after implementation.
Genesis keeps the recommendation tied to evidence.
- Confirm the observed problem.
- Check product fit and safety boundary.
- Apply only the authorized repair scope.
- Re-run equivalent checks before calling it fixed.
Generate a clean technical handoff in one click.
The handoff includes product identity, declared compatibility, delivery method, capabilities, safety boundary, and the verification sequence.
What this item does not claim
This package audits caller-supplied listener registration and handler facts only. It does not scan source, inspect a DOM, instrument a browser, intercept input, measure real tasks, verify cancellation intent, mutate listeners, prove smooth scrolling or accessibility, certify browser compatibility, or establish production performance. The host owns truthful evidence collection, profiling, implementation, gesture and assistive-input testing, publication, monitoring, and rollback.
