what is Client storage silos and the evercookie respawn?

The independent client-side persistence surfaces (localStorage, IndexedDB, the Cache API, window.name) that survive a cookie-only clear. A planted record in one silo that respawns a deleted id from another is the evercookie pattern; a distinctively low multi-silo survival count across reloads is a privacy-tool or automation signature.. Distilled from the richards storage-signals catalog (storage group). The evercookie idea (redundancy + respawn) is why clearing one store was never enough; see supercookies/evercookie.
