+Implemented, reviewed, merged, validated, and applied to this workspace config.
+
+Summary:
+- Added a narrow `yoi ticket init` command.
+- The command creates `.yoi/ticket.config.toml` only when missing and refuses to overwrite an existing config with an actionable diagnostic.
+- Added `ticket_config_scaffold()` for the generated config body.
+- Generated config includes explicit backend config and fixed role tables for intake, orchestrator, coder, reviewer, and investigator.
+- Each generated role uses explicit `profile = "builtin:default"` and explicit default workflow.
+- No runtime fallback was added or loosened.
+- The generated config validates for Ticket role launch planning under the strict validation implemented by `ticket-role-launch-config-strict-validation`.
+- This repository's `.yoi/ticket.config.toml` was updated to the scaffolded explicit role-profile shape for dogfooding.
+
+Implementation:
+- Child commit: `f265098 ticket: add ticket config init scaffold`
+- Merge commit: `merge: ticket init scaffold`
+
+Review:
+- External reviewer `ticket-init-scaffold-reviewer-20260607` approved with no blockers.
+
+Validation after merge:
+- `cargo test -p ticket config --lib`
+- `cargo test -p client ticket_role --lib`
+- `cargo test -p yoi ticket`
+- `cargo fmt --check`
+- `git diff --check`
+- `target/debug/yoi ticket doctor`

 - The main workspace's existing `.yoi/ticket.config.toml` remains backend-only, so a separate main-workspace config update is needed after merge if this workspace should use explicit Ticket role profiles.
