+#              non-blocking, ADDITIVE per #869). (a) DEP-CHECK: the installer
+#              sourced _lib/manifest.sh (the shared framework-manifest reader it
+#              needs for Gate A) unconditionally, so an older host seed that
+#              predates that helper aborted with a bare, obscure
+#              `source: No such file or directory`. It now checks the library
+#              FIRST and FAILS LOUD naming the missing file + the remedy (re-seed
+#              the framework, then retry --component wake) — the dependency is
+#              genuinely required (Gate A cannot be skipped on an enforcement
+#              path), so it fails loud rather than degrading. (b) SYSTEMD SEARCH
+#              PATH: wi_install copies mosaic-wake.service under mosaic home
+#              (systemd/user/, framework-owned) but `systemctl --user` searches
+#              ~/.config/systemd/user/, so the unit was invisible and could not be
+#              enabled/started. install now LINKS the unit into the user systemd
+#              search path (symlink -> the mosaic-home SSOT copy, so upgrades
+#              propagate) and VALIDATES it resolves (search-path entry exists,
+#              dereferences to a readable, well-formed unit; an opportunistic
+#              `systemctl --user cat` probe runs only behind a guard, since the
+#              installer may run where no user manager is live). Both steps are
+#              idempotent (a re-install neither duplicates nor breaks the link).
+#              #869 ADDITIVE: the link target lives OUTSIDE mosaic home, so it is
+#              not a framework-manifest path; ownership of the SSOT unit stays
+#              systemd/** in the single framework-manifest.txt authority — NO new
+#              owned path, NO second ownership authority. framework-manifest.txt,
+#              the install-ordering-guard, and the manifest parity contract are all
+#              UNCHANGED. Only wake-install.sh (+ test-wake-install.sh) changed.
