+## Clean-download installation validation (1.4.1)
+
+On 2026-10-26, a public GitHub main ZIP at `a5ed1e8` was downloaded and
+extracted outside the development checkout. Its `START-HERE.command` was run
+through Bash with new installation, tools and application directories. Automatic
+opening was suppressed only so the installed bundle could be opened explicitly
+through the UI. Setup cloned an independent checkout, created a new Python
+environment, installed its packages, compiled and signed version 1.4/build 5.
+After moving the downloaded folder away, the installed app still opened and
+its catalog displayed all 70 profiles; searching Metroid returned its one profile.
+
+That unmodified release version detected the genuinely newer public release
+1.4.1/build 6 at `d151d54`. Clicking Update now downloaded, compiled, verified,
+replaced and automatically reopened the app. Its version, pinned source revision,
+ad-hoc signature and retained previous bundle were verified; one launcher process
+remained, and the manual check reported it was up to date. Only the validation
+cache location was overridden, keeping test downloads in the separate validation
+directory outside the checkout.
+The original installer checkout remained clean and unchanged.
+
+A second new installation used the current published raw `install.sh` with
+separate source, tools and app directories. All four setup stages completed and
+produced version 1.4.1/build 6; opening it through Finder displayed the home
+window with its profiles and game/key folder selectors. Launcher rebuilds now
+stage and verify before
+replacement, keep backups and roll back on replacement failure. Regression tests
+cover compile failure, replacement failure and preserving an unrelated app.
+All 27 script tests and four documentation checks passed.
+
+This validates clean app installations on an existing Apple silicon Mac, not a
+fresh macOS installation or another physical Mac. Xcode 27.1, Homebrew, Metal
+tools and system build dependencies were already installed; initial installation
+of those system components, browser quarantine prompts, a fresh macOS user
+account and game compilation/gameplay were not exercised by this check. No
+game packages, keys or saves were used or modified.
