 ## Known limitations
 Not built/tested with Xcode in this environment. CVE discovery is broad keyword search and may include unrelated products or omit relevant vulnerabilities. NVD may rate-limit requests. Automatic backport assessment is a future phase.
+
+
+## Version 1.4 security investigation
+The SSH audit collects at most 40 recently modified PHP paths from `/var/www` and up to 30 matching Nginx error lines when accessible. It never modifies remote files. Access may be limited by permissions. The scan is not a compromise determination.
+
+## Branding
+The app icon is compiled from `PHPGuard/Assets.xcassets/AppIcon.appiconset`. The DMG includes a branded image at `.background/PHPGuard-Installer.png`; this is an included asset, not a custom Finder DMG window background layout.

-# PHPGuard 1.3.0 — Release Notes
+# PHPGuard 1.4.0 (Build 5)
 
-- Added read-only APT package provenance and candidate version inventory for PHP CLI and PHP-FPM packages.
-- Added package-origin visibility to server details and exported JSON reports.
-- Corrected the Docker PHP version probe.
-- Preserved compatibility with earlier stored scan results.
-- Updated build number to 4 and version to 1.3.0.
-- Retained the Debug build and signed/notarized DMG release scripts.
+- Added a native macOS application icon and branded installer graphic asset.
+- Added read-only security investigation: recently modified PHP files and selected Nginx error signals.
+- Added investigation coverage reporting and non-conclusive findings.
+- Preserved existing server inventory, Docker inspection, CVE research and scan history.
+- Security signals are not proof of compromise; vendor CVE fix matching remains pending.
 
-## Limitations
-
-APT origin and version information **does not** establish whether a specific CVE is fixed. Ubuntu security backports, package provenance, and vendor advisories still require verification. The CVE Research tab lists keyword-search results, not confirmed server exposures. Scans are read-only and do not remediate systems.
-
-## Build on macOS
-
-`./Scripts/build.sh`
-
-## Release on macOS
-
-`NOTARY_PROFILE=orion-notary ./Scripts/release.sh`
-
-Requires Xcode, a Developer ID Application signing identity, and a configured notarytool keychain profile.
