 ## Installation trial
 
-Pending accepted alpha.2 build and normal uninstall/restore verification.
-This is a retained-state reinstall, not a purge or deletion of the tool's
-historical versions. Provider launches remain deliberately disabled.
+Accepted alpha.2 source: `c11754ab18fa690355ead3f6f87b3accb2975153`.
+Candidate digest: `d4b6ba38a51cc1804047b175c963806850f017a92d88863d187043314414dd90`.
+All 39 acceptance groups passed again from the copied candidate. Active version
+is `0.1.0-alpha.2`; rollback retains alpha.1.
+
+Normal uninstall: PASS. Retained-state restore: PASS. All seven actual agent
+worktrees returned briefs through `/home/user/.local/bin/torch`: PASS. Their
+briefs include the updated canonical smoke instructions despite older worktree
+copies. Model configuration hash, project/installation IDs, offline states,
+saved Codex runtime IDs and all seven branch tips were unchanged across
+uninstall/restore. No provider was launched.
+
+The restored project's `torch setup --yes --json` was a no-op: no commits,
+no mutations, no sessions started. Final doctor reports healthy. Modified owned
+configuration and unique manager history remain legitimate safety warnings,
+not authorization to purge. Uninstall refreshed the manager resume brief;
+that generated file was separately checkpointed on its existing branch, without
+rewriting prior history or landing anything.

+This tests retained-state reinstall, not destructive purge or a fresh installation
+with discarded configuration. New-install setup is covered by isolated real-Git
+regression tests. Provider-authentication and new agent launches were deliberately
+not repeated. Host timers remain uninstalled.
