readClaudeJsonProjectSlice(repoPath) returns the slice keyed to the SPECIFIC
repo path (exact / longest-prefix match), so MCP servers under
~/.claude.json:projects are per-repo: they load only in their own project and
differ across repos. B2b-1 wrongly grouped them with the shared global layer
(reasoning from file location, not the keyed slice). The live sweep captures
the shared layer ONCE from the first repo — folding a per-repo slice into it
would silently drop every other repo's claude.json MCP servers.
Corrected: SHARED_GLOBAL_SOURCES = {user, managed}; the only machine-global
MCP is plugin-provided (plugin: prefix). Per-repo MCP (.mcp.json AND the
~/.claude.json project slice) → delta. Tests updated.
[skip-docs]: internal classifier correction, no user-facing surface yet.
