+# Verdict
+
+For milestone 4's defined bar, the first-run surface now reads as complete.
+A new X11 user can tell what Aman is, how to install it, what success looks
+like, how to validate the install, and where to go when the first run fails.
+This review is documentation-and-artifact based plus CLI help inspection; I
+did not launch the GTK daemon in a live X11 session.
+
+# What A New User Would Experience
+
+A new user now lands on a README that leads with the supported X11 path instead
+of maintainer internals. The first-run flow is clear: install runtime
+dependencies, verify the portable bundle, run `install.sh`, save the required
+settings window, dictate a known phrase, and compare the result against an
+explicit tray-state and injected-text expectation. The linked install,
+recovery, config, and developer docs are separated cleanly enough that the
+first user path stays intact. `python3 -m aman --help` also now exposes the
+main command surface directly, which makes the support story match the docs.
+
+# Top Blockers
+
+No blocking first-run issues remained after the quickstart hotkey clarification.
+For the milestone 4 scope, the public docs and visual proof are now coherent
+enough to understand the product without guessing.
+
+Residual non-blocking gaps:
+
+- The repo still does not point users at a real release download location.
+- Legal/project metadata is still incomplete for a public GA trust surface.
+
+Those are real project gaps, but they belong to milestone 5 rather than the
+first-run UX/docs milestone.
+
+# Quick Wins
+
+- Keep the README quickstart and `docs/media/` assets in sync whenever tray
+  labels, settings copy, or the default hotkey change.
+- Preserve the split between end-user docs and maintainer docs; that is the
+  biggest quality improvement in this milestone.
+- When milestone 5 tackles public release trust, add the real release download
+  surface without reintroducing maintainer detail near the top of the README.
+
+# What Would Make It Distribution-Ready
+
+Milestone 4 does not make Aman GA by itself. Before broader X11 distribution,
+the project still needs:
+
+- a real release download/publication surface
+- license, maintainer, and project metadata completion
+- representative distro validation evidence
+- the remaining runtime and portable-install manual validation rows required by
+  milestones 2 and 3
