What problem does it solve? When an entity's scope changes, its frontmatter title becomes stale while the slug and body stay correct. Hand-editing the title bypasses the aiwf verb route, so the change never appears in aiwf history and the next aiwf check raises a provenance-untrailered-entity-commit warning. ## Core Features & Use Cases - Verb-route title updates: Runs aiwf retitle <id> "<new-title>" for any of the six entity kinds (epic, milestone, ADR, gap, decision, contract) in one atomic commit with proper trailers. - Composite AC retitling: Updates an acceptance criterion's title inside a parent milestone via aiwf retitle M-NNNN/AC-N, regenerating the matching ### AC-N body heading. - Slug and H1 sync: Re-derives the on-disk slug only when it still tracks the old title, preserves slugs set by aiwf rename, and rewrites canonical # <ID> — <title> H1 headings. - Use Case: After a milestone's scope shifts from "user auth" to "identity and access", retitle it so aiwf status, aiwf show, and the roadmap display the correct label without breaking history. ## Quick Start Ask the AI to retitle entity M-0003 to "identity and access management" using the aiwf retitle verb with a reason for the change.
