From e3c1e529d7226649b764baa49908fef901f47b9e Mon Sep 17 00:00:00 2001 From: Sebastien Tardif Date: Wed, 17 Jun 2026 22:17:41 -0700 Subject: [PATCH 1/2] fix: managed install archive extraction path mismatch cargo-dist archives extract to patchloom-/patchloom, but the promotion step expected the binary at managed-bin/patchloom. The rename failed with ENOENT on every real managed install attempt. Fix: after extraction, detect the cargo-dist subdirectory and move the binary to the expected staged path before promotion. Also add end-to-end tests that perform a real managed install (download from GitHub, verify checksum, extract, promote) then start the MCP server and validate JSON-RPC initialize and tools/list responses. These tests would have caught this bug on day one.
