Agent and SSH presets can now be shared with individual users or Everyone, with View and Edit access. Owners retain control of sharing and deletion, and both preset tables show the owner. Using a shared preset still requires the caller's node and SSH permissions; revoked preset access prevents future starts without stopping an existing subshell.

Presets can also be exported as <name>.preset JSON files and imported as private copies through the native file picker. Version 1 validates the file before saving, allows node remapping, and excludes ownership and sharing grants. Duplicate names appear beside the Name field. Cloning preserves stored settings and exact arguments.

Shared fact labels now use stronger visual hierarchy. Sharing controls stay disabled during saves, and import drafts survive Escape and outside clicks.

Validation:

• Three independent review rounds; final pass found zero major or minor issues.
• Build, types, lint, prose, design checks, and all 54 test tasks passed.
• Browser checks covered both preset types, sharing permissions, export/import, duplicate-name recovery, and narrow layouts.
• Regression tests cover access enforcement, revoked restarts, file validation, missing-node remapping, clone fidelity, owner attribution, and pending saves.

Includes database migration 0057 and server/docs changesets. Exported agent presets can contain environment secrets; the sharing and import UI explains this disclosure.

The Nodes list's Share action now opens sharing directly instead of navigating to config. Failed node-sharing reads block edits until a successful retry; focused and browser regressions cover the flow. Incremental review returned zero major or minor findings, and the full local verification passed again.
