The main Sapphire Constellum scope is implemented and deployed at constellum.sapphire-project.me. It supports durable collaboration between people, ChatGPT, Codex, and AI agents across sessions.
Implemented
- Projects, boards, customizable columns, cards, actors and agents, assignments, priorities, dependencies, revisions, and an append-only activity log.
- Kanban and backlog views, search, filters, checklists, comments, attachments, assignees, column drag-and-drop, and AJAX refresh.
- Progress tracking, blockers, handoffs, next actions, artifacts, and a review workflow.
- Contracts for atomic task claims, TTL leases, heartbeat, and release.
- A complete MCP contour, OAuth permissions, access control, audit, and separation of read, write, manage, and destructive operations.
- Real-world use with Codex and ChatGPT.
Remaining before alpha
- Final validation of CGI, FCGI, UI, AJAX, and agent tool contracts.
- End-to-end testing of task claims, heartbeat, lease expiry, recovery, and failure scenarios.
