title: Migrate navigation feature binders to wireUseCase
type: technical-story
status: todo
feature: navigation
depends-on: [01-wire-use-case-helper]
blocks: [08-holistic-validation]

## Goal

Replace the inline `withSpan + withCapture (+ optional withAudit)` block in `packages/navigation/src/di/bind-production.ts` and `packages/navigation/src/di/bind-dev-seed.ts` with a `wireUseCase` call for navigation's single use case (getHeader).

## Why

Navigation's binder pair contributes one of the five top-ten `pnpm fallow` clone groups. Even with a single use case, the inline wrap shape is identical boilerplate that the helper eliminates.

## Done when

- `bind-production.ts` and `bind-dev-seed.ts` call `wireUseCase` for getHeader — no inline `withSpan(... withCapture(...))` pattern remains.
- Audit-bearing status confirmed via manifest check; `auditLog` + schema passed if needed.
- `pnpm test --filter @repo/navigation` green.
- `pnpm typecheck --filter @repo/navigation` green.
- `assertFeatureConformance` does not throw at boot for navigation.

## In scope

- `packages/navigation/src/di/bind-production.ts` — use-case binding block only.
- `packages/navigation/src/di/bind-dev-seed.ts` — use-case binding block only.
- Repository and service bindings stay as-is.
- Controller bindings stay as-is.

## Out of scope

- Controller bindings — deferred follow-up per PRD.
- Changes to navigation use-case implementations, schemas, or tests outside the binder.

## Tasks

- [ ] Read `packages/navigation/src/feature.manifest.ts` — confirm getHeader audit status
- [ ] Read `packages/navigation/src/di/bind-production.ts` — understand inline wrap shape and deps
- [ ] Read `packages/navigation/src/di/bind-dev-seed.ts` — same for dev-seed mode
- [ ] Update `packages/navigation/src/di/bind-production.ts` — replace inline wrap block with `wireUseCase` call
- [ ] Update `packages/navigation/src/di/bind-dev-seed.ts` — same
- [ ] Run `pnpm test --filter @repo/navigation` — verify all tests pass
- [ ] Run `pnpm typecheck --filter @repo/navigation` — verify no type regressions
