NetExperts Support 1.5.4.2 — macOS Universal, Flutter build 73.
Open Door product icons, normal-width access wording, selected upstream security
backports and compatible Rust dependency updates. The existing NetExperts updater,
staff-access installation policy, local approval and authenticated relay fallback
are retained. crypto-bigint RUSTSEC-2026-0387 remains explicitly deferred by the user.

Rust 1.75.0 and isolated Flutter 3.24.5; existing custom engine and native libraries.
Mac builds use the flutter feature (not hwcodec/FFmpeg). The source FFmpeg overlay
is updated for the Windows/Linux builds; it is not linked into these Mac binaries.
Set DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer and
FLUTTER_XCODE___DIAGNOSE_INVALID_DEPLOYMENT_TARGET_AS_ERROR=NO for current Xcode 27.2.
The isolated Flutter tool patch checks every requested architecture independently
because current Apple lipo rejects the old multi-architecture verify invocation.
All packaged Mach-O images were verified Universal with minimum macOS <=11.0.
Both Intel/Rosetta and Apple Silicon version execution passed on this Mac; this
is not a claim that an actual macOS 11 machine was tested.

Paths in build scripts identify the retained build environment; adapt them before
use elsewhere. Use NX_BUILD_PROFILE=macos_inbound_client for Inbound, unset it for
Advanced. The source under source is shared; generated-variants records each
native build's actual VERSION/BUILD_DATE, verified by execution of both slices.
Dependency locks, generated bridge and vendored submodule source are included.
Build outputs, CocoaPods output, machine-local Flutter metadata and logs are
excluded and regenerated by their tools. Retained tools/caches were used; no
clean-room or bit-for-bit rebuild claim is made.
