Projects & saving

• Autosave — your work saves automatically in your browser.
• Projects — click the project name (top-left) to open the project manager: every business as a card showing its description, size, and when you last edited it. From here you switch between them (click a card), and you can rename, duplicate, or delete any project, and once you have more than a handful, a search box filters by name or description. Duplicate forks the whole model under a new name (… (copy)) — the fastest way to try a variant without touching the original.
• Export / Import model — the up/down arrows export and import the whole model as a single model.json — your portable, versionable record of the business. Commit it to git to version it.
• Versions — when a server-backed workspace is available, each project's card in the manager has a history action (clock icon): it opens that project and lets you save named snapshots and restore an earlier one.

model.json is the source of truth

model.json holds every layer — capabilities, entities, behaviour, automations, roles, workflows, agents, and your hand-made fixes. It's what export and code generation build from. See Protecting your fixes.
