+# Evidence-tier install smoke: a REAL clean install + uninstall exercised on a throwaway
+# HOME, across a multi-OS matrix, so the "it installs fine" claim is proven by machine on
+# every push/PR — not just asserted. scripts/smoke-install.sh drives `bash install.sh` into
+# an isolated temp HOME (never the runner's real ~/.claude), checks the exec-form hooks
+# (ME-23) land with the _forge marker, proves `forge init --settings-only` is idempotent and
+# fails on corrupt JSON (RA-04), reverses cleanly on uninstall, and — the load-bearing bit —
+# installs under a path CONTAINING A SPACE and runs an installed guard from it to guard the
+# RA-12 / ME-23 quoting regression. The full test suite also runs here so >=20 behavior is
+# verified on macOS too, not only Ubuntu.
+#
+# TODO(windows-git-bash): the guards are bash scripts and install.sh uses POSIX `ln -s`, so a
+# Windows run needs Git Bash AND symlink-capable checkout (Developer Mode / core.symlinks).
+# That is fiddly enough to defer — add `windows-latest` here behind `shell: bash` with the
+# symlink assertions softened once someone can validate it on a real Windows runner.

+#!/usr/bin/env bash
+# Clean-install / uninstall smoke test — the evidence-tier proof that `install.sh` and
+# `forge init` actually wire (and unwire) global config correctly, end to end, on a REAL
+# filesystem. Everything runs inside throwaway temp HOMEs created here and torn down on
+# exit, so the real ~/.claude / ~/.forge are never touched. Portable to macOS's bash 3.2
+# (no associative arrays, no ${var,,}) and clean under `shellcheck --severity=error`.
+#
+# What it proves:
+#   1. `bash install.sh` (driven with HOME=<tmp>) creates resolvable asset symlinks, merges
+#      the exec-form hooks (command:"bash" + args + the _forge marker) into settings.json,
+#      and leaves the guard scripts present + executable.
+#   2. `forge init --settings-only` (FORGE_SETTINGS_PATH into the temp HOME) exits 0 and is
+#      idempotent — a second run leaves the file byte-for-byte unchanged.
+#   3. The uninstall path removes the Forge hooks AND the symlinks, exit 0.
+#   4. A corrupt settings.json makes `forge init --settings-only` exit non-zero (RA-04).
+#   5. Installing under a path WITH A SPACE and then executing an installed guard proves the
+#      ME-23 exec form + RA-12 quoting survive spaces (the concrete RA-12/ME-23 regression).
