What

Every kitchen-sink Detox e2e test now relaunches straight into its use case via launchArgs: { directUseCase } (new reloadUseCase helper in e2e/utils/detox.ts), instead of safeReloadApp() + navigateToTestCase() (relaunch → home → expand quick-nav grid → tap, ~60-90s/test).

The app already supported this (App.native.tsx renders the use-case component at root inside all providers); SheetKeyboardFitContent was the only file using it. This rolls it out everywhere.

Why

The 71-min run that started this was a degraded-runner cold-bundle flake, not a regression. The steady cost is the per-test home→quick-nav navigation. A first attempt to fix it by rebalancing shards was a net regression (built on noisy single-run estimates; two high-variance files spiked together). Reverted. The real lever is removing the navigation itself.

Scope

• 23 e2e files converted (relaunch-per-test preserved → same isolation, just no navigation).
• noRngh keeps disableGestureHandler; CompilerExtraction keeps its in-test build; check-rngh-status (home-screen test) and SheetKeyboardDrag (describe.skip) untouched.
• Shard matrix is the prior 4-shard layout — this run measures the new per-file times; the matrix will then be tuned to ≤30 min/shard (and collapsed to 3 shards if there's headroom).

Validation

tsc -p e2e/tsconfig.json + oxfmt + oxlint + check-ios-detox-shards.mjs all green. Runtime = this Detox run.
