Keep event handlers and client-only callbacks separate from Smart render bundles while preserving ordinary QRL grouping and existing component-strategy behavior.

Summary by CodeRabbit

• Bug Fixes
  • Smart builds now keep event-handler callbacks separate from render bundles, including callbacks that capture state.
  • Client-only interaction code is named separately, while manual naming overrides are preserved. This helps prevent code needed only for later interactions from being included with rendering code. Other segments continue to use their existing names.

📝 Walkthrough

Smart entry strategies now leave event handlers and event$ segments without entries, including when they capture state. Vite smart builds assign fallback names to client-only segments. Tests cover optimizer entry assignments, Vite chunk placement, and visible-task initialization.

Changes: Smart interaction boundaries

Layer / File(s)	Summary
Keep event handlers outside smart entries packages/optimizer/core/src/entry_strategy.rs, packages/optimizer/core/src/fixtures/smart-lifted-captures.tsx, packages/optimizer/core/src/test.rs, packages/ts-optimizer/src/optimizer/segment/entry-strategy.ts, packages/ts-optimizer/tests/optimizer/segment/*, packages/ts-optimizer/tests/optimizer/snapshot-options.ts, packages/optimizer/core/src/fixtures/smart-visible-task-heavy-library.tsx	Both optimizer strategies leave event-handler and event$ segments without entries, including when they capture state. Tests cover lifted captures, entry assignments, and production snapshots.
Name and split client-only chunks packages/qwik-vite/src/plugins/plugin.ts, packages/qwik-vite/src/plugins/plugin.unit.ts, packages/qwik-vite/src/plugins/rolldown.unit.ts, packages/qwik/src/core/tests/use-visible-task.spec.tsx, .changeset/smart-interaction-boundaries.md	Vite uses segment hashes as fallback names for smart client-only segments, unless a manual mapping supplies a name. Tests check entry assignments, client-only chunk placement, SSR output, and visible-task updates when initialization yields. The changeset declares patch releases for core and optimizer.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Suggested reviewers: wmertens

Merge Risk: ⚪ Minimal · up to 2a476

No actionable merge-blocking risk remains from the reviewed changes. The retained import does not eagerly load the optimizer in the supported build.

Security architecture risk: 🔵 Low · up to 2a476

The change separates interaction code from render bundles while preserving manual grouping and existing server/client stripping controls. No new security exposure was established. Risk remains low because downstream build and deployment compatibility was inspected but not exercised.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated exposure is generated client bundle composition for applications using Smart strategy. The changed decisions consume compiler metadata and build configuration, not a newly introduced runtime input carrying additional authority.

Trust Boundaries and Controls

• inferred — Chunk separation is a loading boundary, not an authorization or confidentiality boundary. Client-only segments remain emitted client assets, and manual grouping remains available; security continues to depend on the separate server/client stripping controls.

packages/qwik-vite/src/plugins/plugin.ts: 1

5-5: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Replace the cross-package relative import with a package-level import or a local helper.

packages/ts-optimizer/src/index.ts defines the package boundary and keeps ./optimizer/** internal. Importing isStrippedSegment from that internal path couples qwik-vite to the optimizer source layout. Re-export the function from the package entry point and import it from @qwik.dev/ts-optimizer, or keep the small helper local to plugin.ts.

This is a maintainability and package-boundary issue. The inspected code does not establish a build or runtime failure.
