Struct WalFloorState 

pub struct WalFloorState {
    pub namespace_id: NamespaceId,
    pub floor_seq: ChangeSeq,
    pub verified_at_ms: u64,
    pub updated_at_ms: u64,
}

Lower bound of retained WAL/change history: the symmetrical pair to wal/head.json.

Updated only by monotonic compare-and-swap on its own etag; never consulted for live commit visibility. Missing, stale, or unverifiable floors mean “retain more history”, never less. The floor is necessary but not sufficient for deletion: below-floor objects are candidates, and actual deletion additionally requires delete-time re-verification (format spec, “Garbage collection”).

Fields

namespace_id: NamespaceId

Namespace whose retained history this floor bounds.

floor_seq: ChangeSeq

Earliest sequence at which incremental replay remains promised.

verified_at_ms: u64

Unix-millisecond wall-clock time when the referenced manifest basis was last verified.

updated_at_ms: u64

Unix-millisecond wall-clock time stamped by the successful floor update attempt.
