0009: One canonical slug names the Jira project, workspace and git repo

• Status: Accepted
• Date: 2026-08-28

Context

orion new derives a workspace slug from the idea (internal/workspace.Slugify) and, separately, a Jira project key from the same idea (internal/tracker.DeriveKey, constrained to Jira's uppercase, 2-10-character project-key rules). Derived independently, these risk a workspace named one thing and its Jira project or git repo named a related-but-different thing for the same piece of work.

Decision

One canonical slug is derived once from the idea and reused to name the Jira project, the workspace directory and the git repo.

Consequences

• A person moving between the tracker, the filesystem and GitHub sees the same name everywhere, rather than needing a mapping table between them.
• Anywhere a new identifier is derived for one of these three surfaces, it derives from the same canonical slug rather than independently re-deriving from the idea text (which, per internal/tracker's own design, is not guaranteed to produce the same result twice against Jira's stricter key constraints).
