+    """release_smoke.py's MACOS_FILES (checked above) is a manifest-
+    completeness gate, not what actually ships -- build_macos_swift_app.sh
+    has its own, completely separate hand-maintained RUNTIME_FILES array
+    that controls what's actually copied into the signed app bundle. A
+    script can pass every assertion above while still being silently absent
+    from RUNTIME_FILES, because the two lists were never cross-checked.
+
+    This happened for real, discovered by running scanner.sh from this
+    machine's actual installed runtime: modules/macos/idle_cpu.sh,
+    privacy.sh, and devtool_updates.sh were all missing, so `source` failed
+    for each (no `set -e`, so the scan kept going with three collector
+    functions permanently undefined) -- scanner.sh printed "command not
+    found" for each and the resulting scan_result.json silently reported
+    `collection.complete: true` with those three sections simply absent.
+    Separately, scripts/login_items.sh and modules/approval_token.sh were
+    also missing, which fails closed instead (pinnedApprovalTokenModule()
+    returns nil when the sealed payload doesn't contain the module) -- but
+    that means every cleanup preview/execute and login-item removal in a
+    real signed build failed outright since approval_token.sh was extracted
+    out of cleanup.sh in PR #67, with no test anywhere catching it because
+    every test runs against the checkout directly, never the installed
+    runtime tree a real user's app actually uses.
