The objective is a tall order. The quantum-resistant cryptographic data needed to transparently publish TLS certificates is roughly 40 times bigger than the classical cryptographic material used today. Today’s X.509 certificates are about 64 bytes in size, and comprise six elliptic curve signatures and two EC public keys. This material can be cracked through the quantum-enabled Shor’s algorithm. Certificates containing the equivalent quantum-resistant cryptographic material are roughly 2.5 kilobytes. All this data must be transmitted when a browser connects to a site.

writable: false means no code can reassign window.Audio to a different value. configurable: false means no code can even call Object.defineProperty again to change those settings. If fermaw’s initialisation code tried to restore the original Audio constructor (a perfectly sensible defensive move) the browser would either fail or throw a TypeError. The hook was permanent for the lifetime of the page.
