No installers are published for general use. The v0.1 protocol spec and threat model are public (still in draft); the desktop client is in progress. When the first signed build lands it will show up here and on GitHub releases — every artifact with its published SHA-256 so you can verify it.
No dates and no cadence promise — builds ship when they're ready to trust, not on a schedule. Until then, the spec and the source are the thing to read.
