Backlog Delta Commands

delta commands are grouped under backlog because they describe backlog graph drift and impact, not source-code diffs.

Command Group

specfact backlog delta status --project-id <id> --adapter <github|ado>
specfact backlog delta impact <item-id> --project-id <id> --adapter <github|ado>
specfact backlog delta cost-estimate --project-id <id> --adapter <github|ado>
specfact backlog delta rollback-analysis --project-id <id> --adapter <github|ado>

What Each Command Does

• status: compares current graph vs baseline and summarizes added/updated/deleted nodes and edges.
• impact: traces downstream effects for a changed item.
• cost-estimate: estimates effort from detected delta scope.
• rollback-analysis: identifies likely breakage if recent delta is reverted.

Baseline

status, cost-estimate, and rollback-analysis rely on a backlog baseline graph (default .specfact/backlog-baseline.json).

Generate/update baseline with:

specfact project snapshot --bundle <bundle>
