Feature Workflows

Attachments

AttachmentSupport.swift accepts picker, pasteboard, and drag/drop input.
Supported images are decoded and sent as base64 RPC image content; formats Pi cannot send directly are normalized to PNG.
Other readable regular files remain path references—contents are not silently inlined.
Attachment-only prompts receive useful fallback text, and missing/folder inputs produce visible errors.

PromoteToProject.swift splits filesystem policy (PromoteToProjectService), progress state (PromoteToProjectWorkflowModel), and modal UI.
Project name is slugged under the configured project folder; normalized and symlink-resolved paths must remain inside that root.
Non-empty folders are reused only when their .pinative/promote-to-project.json marker matches project, destination, and source session.
Writes are create-if-missing, making retries non-destructive.
Output can include README.md, project plan/log, AGENTS.md, promoted-chat.md, and optional git init.
On success, AppModel.swift registers/reuses the project, starts a context-rich project chat, archives the source Quick Chat, and cleans its runtime.

Pin/archive flags are PiNative metadata; the underlying Pi session file is retained.
Pinned chats are promoted to a global sidebar section.
Archived chats disappear from normal lists and can be restored from the right pane.
Working or queued chats cannot be archived until stopped/completed.
