 | `multi-agent-workflow` | Partly. The sibling coder/reviewer loop, intent packet, branch-local review, and merge-ready dossier are useful product concepts. | Heavy Yoi dogfood specifics: Git worktrees, commits, cargo/nix validation, branch cleanup, docs/report conventions, and parent/child policy. | Split into builtin `multi-agent-workflow` for role loop + dossier, and workspace dogfood extension for Git worktree/cargo/nix mechanics. |

+## Slug and workspace Ticket settings migration decision
 
 Use explicit dogfood slugs for workflows whose semantics differ from the public builtin workflow. Same-slug workspace overrides are allowed for local wording/policy tweaks of the same public contract, but they should not be used to hide Yoi repository Git/worktree/cargo/nix/merge semantics behind a public slug. This avoids accidental shadowing when a user expects `multi-agent-workflow` to mean the generic builtin role loop.

 4. **Vocabulary migration**
    - Sweep active workflow text, prompts, docs, and Ticket UI wording for `Action required`, `Attention required`, and old preflight lane language.
