Killed: - rebuild_and_restart (in-container cargo self-compile): the MCP tool, the `rebuild` chat command in all four transports, the web-ui bot command, and the underlying function. This was the path that caused the exec() deadlocks. - upgrade_sled gateway MCP tool: second entry point to sled upgrades, defaulted to serving the gateway's own macOS binary to Linux sleds. - GET /api/huskies-binary (both sled and gateway route trees): served current_exe(), wrong platform when the gateway is macOS. Superseded by /api/artifacts/ which now also serves on the gateway route tree. - `huskies upgrade` CLI subcommand and --source flag: third way of doing the same download-and-replace. Escape hatch for a bricked sled is `docker cp` + restart. Kept, distinct jobs: `project-rebuild` (container/image updates), `rebuild gateway` + script/local-release (gateway self-update).
