The CLI honors them for search and every walker-based op; MCP `search_files` (and presumably `batch_replace`, `batch_tidy`, `list_files`) walk the excluded files too. `[write_policy]` is honored because writes go through the engine, so the config is partially applied, which is worse than not at all: an agent that excluded `*.log` or `vendor/**` in config sees them via MCP.\n\n## Reproduction\n\n```sh\nprintf '[exclude]\\nglobs =…",

The module documents that all sync I/O goes through `PatchloomService::blocking` / `spawn_blocking` so one slow operation cannot starve other sessions.

That parser requires an IP literal and, for IPv6, bracket syntax. So `--host ::1` becomes `::1:8080` (invalid) and `--host localhost` fails outright.
