Mosaic 0.1.2

Mosaic v0.1.2

Added

• Pi (pi.dev) is now a supported provider, joining Claude Code,
  OpenCode, Gemini, and Codex. Detection (pi --version), spawn,
  resume by session id, and full session listing — local and remote
  over SSH. Pi sits between OpenCode and Gemini in the new-session
  dropup, AddWorkspace cards, and Settings → Providers.
• Live model picker for Pi in Settings → Providers, populated from
  pi --list-models (~70+ models). Type to filter; the field accepts
  any provider/model notation Pi understands, including the
  :thinking suffix (e.g. sonnet:high).
• Keychain-SSH setup helper for remote workspaces. When a remote
  workspace can't authenticate, an inline banner appears above the
  session list with a "Set up Keychain SSH →" button. The guided
  modal:
  • Idempotently appends AddKeysToAgent yes / UseKeychain yes to
    ~/.ssh/config (skips if already configured).
  • Detects private keys under ~/.ssh/ and lets you pick which to
    add. Already-loaded keys are flagged so you don't re-add them.
  • Runs ssh-add --apple-use-keychain per selected key. macOS shows
    its native passphrase dialog; the passphrase is stored in
    Keychain. From then on, ssh (interactive panes AND background
    polls) unlocks your key automatically — including across reboots.
  • Mosaic never sees or stores your passphrases. Apple's Keychain
    holds them, ssh-agent retrieves them.
• Remote-host status banners: when a remote workspace's SSH probe
  fails, the panel surfaces what kind of failure it is — needs auth
  (orange, fixable via Keychain SSH), host key changed (red, run
  ssh user@host once in Terminal to inspect), unreachable (gray,
  network/VPN issue).

Changed

• First-connect SSH no longer prompts for yes/no in the pane.
  Both the session-discovery probe and interactive pane spawns now use
  StrictHostKeyChecking=accept-new, which silently adds new hosts
  to known_hosts on first connect. Changed keys for already-known
  hosts still fail loudly so the host-key banner can warn you.
• Settings → About version badge now reads 0.1.2.

Fixed

• Pi's --list-models writes its table to stderr when stdout is
  piped (it auto-detects TTY vs. pipe and routes "human output"
  away from a captured stdout). The introspection parser now reads
  whichever channel actually has the table — fixes "introspection
  failed" on the Pi row in Settings → Providers.

Notes

• No data migration required. v0.1.1 → v0.1.2 carries over all
  workspaces, tab state, sessions, and settings.
• Universal binary as before — runs on Apple Silicon and Intel Macs
  from a single DMG.

Install

1. Download Mosaic_0.1.2_universal.dmg below.
2. Open the DMG, drag Mosaic into Applications (replace the
   existing copy if you have v0.1.1 or v0.1.0).
3. Launch normally — the macOS Gatekeeper trust granted to a previous
   version carries over.
