Add extensible remote session backends, safe ownership and restore handling, and pane-scoped shell integration over the existing SSH connection.
Keep iOS workspaces in memory and rebuild expired Activity targets on demand. Integrate session selection into Connection Journey with consistent controls, cancellation behavior, and localized counts.
Reuse card content across macOS and iOS with platform-sized icons and matching card heights. Add the shared Color field below Package and preserve selection, drag, and execution behavior.
Migrate stored snippets to V51 and write color in Vault V2 while retaining V1 decoding and guarding against lossy V1 writes.
Validation: macOS focused snippet, migration, architecture, and localization tests pass; 30 iOS focused tests pass; Swift format and localization checks pass. Full macOS testing also reports failures in unchanged KeyExport, MCP, and Agent suites.
Add native security key registration, reference import, and signing on macOS and iOS. Store references in Vault metadata and route authentication through connection, Assistant, MCP, and agent forwarding flows.
Preserve signing cancellation and actionable authentication errors for security keys and Secure Enclave. Pin the released libssh2 forks as nested submodules and refresh package resolution.
