//! Mark-and-sweep garbage collection (format spec, "Garbage collection").
//!
//! GC, floor advancement, and explicit namespace repair are the only code
//! paths that list the store. Nothing sweeps by default: callers opt in
//! through the admin endpoint or an explicit maintenance-step option.
//! Writers never coordinate with GC, so a sweep can race an in-flight
//! publish or checkpoint creation. The grace window, delete-time
//! re-verification, and retain-on-ambiguity defaults close those races. When
//! in doubt, this module retains.
