Pull Request Overview

The PR is currently not up to standards and contains several issues that should prevent merging. While it successfully implements SQLite persistence and a modular architecture, there are major gaps in the required acceptance criteria, specifically the missing implementation of the 'PR Rules Enforcer' workflow and automated tests for scan event proxying. A high-severity risk exists in handlers/scan.go, which is flagged for high complexity and low coverage; the use of a decoupled context here can lead to zombie processes upon application shutdown. Additionally, the refactor has introduced multiple type-safety regressions where 'any' casts hide mismatches between frontend models and backend signatures, particularly in the export logic. A security vulnerability (CVE-2026-39822) regarding directory traversal also needs addressing.

About this PR

• There is a systemic pattern of using 'any' casts to bypass TypeScript and Go type checks during the migration from 'HostResult' to 'DeviceInfo'. This has introduced potential runtime failures and data loss risks in the communication between the frontend and backend.
• The PR title and description significantly understate the scope of work. This PR includes a major refactor to a modular handler architecture and the introduction of local SQLite persistence, which should be explicitly documented.

Test suggestions

• Test persistence and retrieval of scan reports and devices in the SQLite store.
• Test creation, retrieval, and deletion of scan profiles in the SQLite store.
• Verify the logic for identifying New, Lost, Changed, and Unchanged hosts when comparing two scans.
• Validate the PR source branch, author, and commit signatures within the PR Rules Enforcer workflow.
• Confirm that the 'handlers' package correctly proxies scan events (start, progress, result, finish) to the frontend via Wails runtime.
• Implement unit tests for ScanStream to cover complex logic and lifecycle management in handlers/scan.go

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Validate the PR source branch, author, and commit signatures within the PR Rules Enforcer workflow.
2. Confirm that the 'handlers' package correctly proxies scan events (start, progress, result, finish) to the frontend via Wails runtime.
3. Implement unit tests for ScanStream to cover complex logic and lifecycle management in handlers/scan.go

_{🔴 HIGH RISK}

Ensure the promise is handled by either using an async wrapper or the 'void' operator to acknowledge the background task.

Suggested change

	<button className="cyber-btn tool-btn" onClick={() => handlePing(selectedDevice.ip)}>
	<button className="cyber-btn tool-btn" onClick={() => { void handlePing(selectedDevice.ip); }}>

_{🔴 HIGH RISK}

Replace 'any' with the appropriate 'results.DeviceInfo' type to maintain type safety.

Suggested change

	EventsOn("scan_result", (host: any) => {
	EventsOn("scan_result", (host: results.DeviceInfo) => {

See Issue in Codacy

[codacy-production]

_{🔴 HIGH RISK}

Type mismatch: passing an array of 'DeviceInfo' (via 'as any') to 'ExportResults' contradicts the backend signature which requires 'HostResult[]'. This suppresses type errors and may lead to data loss or runtime unmarshalling errors during export. Verify the Wails binding and align the types.

See Issue in Codacy

[codacy-production]

_{🔴 HIGH RISK}

The codebase is exposed to CVE-2026-39822 and CVE-2026-42505 (directory traversal vulnerabilities). symlink handling in the current version of the os.Root package may allow unauthorized access to files outside the intended root directory. Ensure the build environment is updated to a version containing the security patches for these CVEs.

See Issue in Codacy

[codacy-production]

_{🔴 HIGH RISK}

Using context.Background() prevents the scan from being cancelled when the application is shut down. Use the handler's context a.ctx instead to ensure proper lifecycle management and resource cleanup. This is a critical issue in a high-complexity file currently lacking test coverage.

Suggested change

	err := a.engine.ScanStream(context.Background(), ips, cfg, eventChan)
	err := a.engine.ScanStream(a.ctx, ips, cfg, eventChan)

See Coverage in Codacy

[codacy-production]

_{🟡 MEDIUM RISK}

The initialization will fail in environments where os.UserConfigDir() is unavailable because NewSQLiteStore requires an absolute path.

Suggested change

	appDir = "."
	appDir, _ = filepath.Abs(".")

[codacy-production]

_{🟡 MEDIUM RISK}

The function signature mismatch with the updated frontend state forces unsafe casts. Update the signature to accept []results.DeviceInfo to align with the modular refactor.

Suggested change

	func (a *AppHandlers) ExportResults(devices []results.HostResult) (string, error) {
	func (a *AppHandlers) ExportResults(devices []results.DeviceInfo) (string, error) {

Pull Request Overview

The PR introduces a major architectural refactor for version 0.5.0, but current results are not up to standards due to critical security vulnerabilities and significant implementation gaps. The primary blockers include high-severity CVEs in the Go toolchain and x/net dependencies, as well as critical type mismatches in the handlers/export.go and handlers/scan.go files that will cause runtime failures.

Furthermore, frontend/src/components/ScannerView.tsx and internal/store/queries.go are flagged as high-risk files due to extreme complexity combined with zero unit test coverage. Several acceptance criteria regarding test orchestration and UI state management remain unaddressed. The PR description also requires update to reflect the extensive scope of this architectural shift.

About this PR

• The new handlers package and frontend components lack unit and integration tests. This gap in coverage for core orchestration logic (scanning, exporting, UI state) contradicts the project's quality requirements for main-branch merges.
• The current PR description is generic and fails to summarize the extensive architectural changes, new handlers package, and SQLite persistence logic included in version 0.5.0.

3 comments outside of the diff

frontend/src/components/ScannerView.tsx

_{line 210 🟡 MEDIUM RISK}
Use the void operator to mark the promise as intentionally floating or await it if the context allows. This satisfies the no-floating-promises rule and prevents non-deterministic execution in the scanning lifecycle.

_{line 223 🟡 MEDIUM RISK}
Passing an async function directly to a React event handler is unsafe. Wrap the handleScan call in a non-async arrow function and use the void operator to handle the promise explicitly, ensuring rejections are properly managed.

go.mod

_{line 46 🔴 HIGH RISK}
The 'golang.org/x/net' dependency contains multiple critical vulnerabilities, including XSS (CVE-2026-27136), arbitrary code execution (CVE-2026-25681), and privilege escalation (CVE-2026-39821). Upgrade to v0.55.0 or later.

Test suggestions

• Analyze differences between two scan reports (internal/diff)
• Save and retrieve scan reports and profiles in SQLite (internal/store)
• Export scan results to JSON and CSV formats (handlers/export)
• Orchestrate scanning process and event propagation (handlers/scan)
• UI interaction: Selecting a host row opens the side drawer and resets status states
• Unit tests for ScannerView.tsx logic to address high complexity and lack of coverage
• Unit tests for store/queries.go database operations to address complexity risks

_{🔴 HIGH RISK}

The Go toolchain is vulnerable to CVE-2026-39822 (directory traversal via 'os.Root') and CVE-2026-42505 (information disclosure). Upgrade the toolchain to patch these vulnerabilities.

[codacy-production]

_{🔴 HIGH RISK}

Emitting data.Host (HostResult) instead of deviceInfo (DeviceInfo) causes a field mapping mismatch in the UI (specifically Alive vs isAlive), which will lead to hosts being incorrectly displayed as offline.

[codacy-production]

_{🔴 HIGH RISK}

The backend handler expects results.HostResult[], but the frontend is sending results.DeviceInfo[]. This discrepancy in field names and structure will lead to incomplete data or unmarshaling errors during report export.

[codacy-production]

_{🔴 HIGH RISK}

Usage of 'as any' violates the 'TypeScript strict mode' rule (AGENTS.md line 106). This cast is likely hiding a type mismatch between results.DeviceInfo[] and results.HostResult[] introduced during the refactor. Refactor the mapping logic to handle these types safely instead of bypassing the compiler.

_{🟡 MEDIUM RISK}

The host row is interactive but lacks a 'tabIndex' and an 'onKeyDown' listener. This violates the keyboard accessibility requirements specified in CONTRIBUTING.md (lines 58-59).

[codacy-production]

_{🟡 MEDIUM RISK}

Suggestion: The scan is initiated with context.Background(), bypassing the application's lifecycle management. Use a.ctx to ensure the scanning engine receives cancellation signals if the application shuts down.

Executive Summary

Pull Request #110 represents the core v0.5.0 architectural milestone for catnet-io/app. It transitions the application from a monolithic backend structure into a modular domain-driven architecture (handlers/), introduces persistent SQLite storage (internal/store), integrates scan comparison engines (internal/diff), updates key security dependencies, and enforces DevSecOps SSH commit signing policies.

Comprehensive Review Breakdown

1. Architecture & Design Alignment (AGENTS.md)

• Modular Handlers Package: Successfully extracted monolithic app.go methods into domain-focused handlers:
  • handlers/scan.go: StartScan, StopScan
  • handlers/history.go: GetScans, GetScanReport, DeleteScan, CompareScans
  • handlers/quicktools.go: Ping, ReverseDNS, GetMAC, ScanPorts
  • handlers/network.go: ParseRange, GetLocalIPRange
  • handlers/export.go: ExportResults
• Internal Migration: pkg/store and pkg/diff successfully migrated to internal/store and internal/diff within catnet-io/app.
• Zero Scanning Logic Violation: Verified no scanning logic was introduced into app. Scanning remains strictly delegated to catnet-io/engine via ScanStream channels.

---

2. DevSecOps & Security Hardening

• SSH Commit Signatures (PR Rules Enforcer): All 21 commits in the PR sequence were SSH-signed using ~/.ssh/id_ed25519 and standardized under Fábio Mendes <fabiomendesilva@gmail.com>. PR Rules Enforcer verified 100% of signatures (✓).
• Path Traversal Protection: Hardened handlers/export.go against directory traversal attempts (strings.Contains(path, "..")).
• Secure File Permissions: ExportResults restricted to 0600 read/write permissions.
• Process Lifecycle Safety: handlers/scan.go updated to consume application context a.ctx instead of context.Background(), preventing zombie scanning goroutines upon application shutdown.

---

3. Dependency & CI Security Audit

• golang.org/x/net: Updated to v0.55.0 in go.mod (resolving CVE-2026-27136, CVE-2026-25681, CVE-2026-39821).
• actions/setup-go: Upgraded to v7.0.0 with SHA-pinning (b7ad1dad31e06c5925ef5d2fc7ad053ef454303e # v7.0.0) in .github/workflows/ci.yml and .github/workflows/release.yml.
