03-update-generator-templates	2026-05-13-binder-wrap-helper	Update feature generator templates to emit wireUseCase call shape	technical-story	done	core-shared	01-wire-use-case-helper

Goal

Update turbo/generators/templates/feature/src/di/bind-production.ts.hbs and bind-dev-seed.ts.hbs so that pnpm turbo gen feature scaffolds new features with wireUseCase calls instead of the longhand inline withSpan + withCapture form.

Why

New features scaffolded after the migration would otherwise drift back to the inline form, re-introducing the clone group. The generator is the canonical source for scaffolded binder shape; updating it closes the loop.

Done when

• turbo/generators/templates/feature/src/di/bind-production.ts.hbs emits wireUseCase(...) calls (not inline withSpan + withCapture) for the placeholder use case.
• turbo/generators/templates/feature/src/di/bind-dev-seed.ts.hbs emits wireUseCase(...) calls for the placeholder use case.
• Running pnpm turbo gen feature testfeature produces binder files that call wireUseCase and pass pnpm typecheck && pnpm lint && pnpm test && pnpm conformance && pnpm fallow:audit && pnpm coverage:diff (or the generated feature is cleaned up after verification).

In scope

• turbo/generators/templates/feature/src/di/bind-production.ts.hbs
• turbo/generators/templates/feature/src/di/bind-dev-seed.ts.hbs
• Any supporting type imports in the templates that change as a result (e.g. dropping ProductionUseCase intermediate type if the helper absorbs it).

Out of scope

• Generator templates for events, jobs, realtime, or core-packages — those do not produce binder files with use-case wrapping.
• Runtime behaviour changes — the generated output must be semantically equivalent to the old inline form.

Tasks

• Update bind-production.ts.hbs and bind-dev-seed.ts.hbs in turbo/generators/templates/feature/src/di/ to emit wireUseCase calls; verify a test-scaffold of a new feature produces correct binder output and all gates pass on this commit.
