A local document already installed these paths. Consume their older public envelope entries without re-applying values over its exact hydration state.

Persist small preferences synchronously and return each owner’s actual result. Heavy caches use serial async IDB writes; pagehide never encodes large content.

Drain preferences, then await all queued heavy writes for explicit callers.

Move persisted component IDs to the generic namespace without changing saved values or expiry. An existing destination entry wins over its legacy entry.

Queue one disk read per owner. Failed private reads cannot overwrite unseen durable data; public caches may recover through the ordinary server source.

Restore shared caches after bootstrap state installation. Feature caches install with their own modules, before those modules become renderable.

Retry a completed failed owner read through the same deduplicated boundary.
