Command-line options

numen opens the vault you had last and reads its settings from the usual place. The flags below are for the times you want a single launch to do something else; none of them is written down, and the next launch is back to normal.

numen -vault Research

-index	Path to the index database.
-registry	Path to the vault list.
-vault	The vault to open: a name, a path or an identity; the one opened last by default.
-mcp-addr	Where agents reach this vault; anything but a loopback address opens it to the network.
-no-mcp	Do not let agents reach this vault.
-interface-scale	How large the interface is drawn, 1 being as designed; this launch alone.
-text-scale	How large the text a person reads is set, 1 being as designed; this launch alone.
-rebuild-index	Read every file and put it in the index again, whatever the index remembers.

The ones worth knowing

-vault takes a name, a path or a vault’s identity. It is the quickest way to keep two vaults open in two windows, or to put a shortcut on the desktop that opens the one you work in.

-rebuild-index reads every file again and puts it back in the index, whatever the index thought it already knew. Nothing in your vault is touched — the index is built from your files and can always be built again. Reach for it when search is answering with something stale.

-interface-scale and -text-scale try a size out for one launch. Choosing a size in the window is what writes it down; these do not.

-no-mcp starts the window with no door for agents at all. Without it, agents reach this vault at 127.0.0.1:7717, which is this machine and nothing else; -mcp-addr moves that, and anything other than a loopback address opens the vault to the network.

The other program, numen-cli, takes flags of its own.
