[package] --all-platforms cannot be combined with explicit p

Error message

[package] --all-platforms cannot be combined with explicit platform or arch flags

What it means

Thrown by resolveBuildMatrix in apps/desktop/scripts/package.mjs when --all-platforms is combined with explicit --win/--mac/--linux platform flags or --x64/--arm64 arch flags. --all-platforms is an exclusive macro that expands to the fixed MAC_ALL_PLATFORM_TARGETS matrix, so per-target flags are contradictory and rejected up front rather than silently ignored.

Solutions

1. Remove the explicit platform/arch flags and keep only --all-platforms.
2. Or drop --all-platforms and list the specific platforms/arches you want.
3. Check package.json scripts and CI YAML for hardcoded flags that get merged with CLI args, and clean up the duplication.

Example fix

# before
node apps/desktop/scripts/package.mjs --all-platforms --x64

# after
node apps/desktop/scripts/package.mjs --all-platforms

// Before spawning, assert the flag combination is legal
if (argv.allPlatforms && (argv.platform?.length || argv.arch?.length)) {
  console.error("--all-platforms cannot be combined with --platform/--arch flags");
  process.exit(2);
}

When it happens

Trigger: Running e.g. `node scripts/package.mjs --all-platforms --x64` or `--all-platforms --mac`; passing flags through an npm script that already includes platform defaults; CI config copying a per-platform invocation and appending --all-platforms.

Common situations: Scripts that layer default flags (package.json scripts adding --x64) colliding with an operator-supplied --all-platforms; local shell history reuse.
