Mandu Hydration

Use for islands, partials, client boundaries, or hydration diagnostics.

• Server pages remain server-owned; move interactive state into an island.
• Use explicit client-boundary metadata and serializable props.
• Never import a generated client artifact directly.
• Keep HTML, manifest, and client asset URLs pinned to one build generation.
• Treat missing client assets or hydration samples as failures when the route

declares hydration.

Run the targeted hydration tests requested by the plan, then mandu.agent.verify --changed --json --write.
