Expand description

A revalidation outcome with the writer-computed freshness state it leaves behind (replay never re-derives policy).

Fields§

§checked_at_ms: u64

When the check happened, epoch ms.

§outcome: u8

The outcome tag (crate::ttl::Outcome::as_tag).

§content_hash: Option<u64>

The node’s content hash after the check.

§etag: Option<&'a str>

The node’s entity tag after the check.

§interval_s: u32

The revalidation interval it leads to, seconds.

§checks: u16

Revalidations observed (saturating).

§changes: u16

Content changes observed (saturating).

§last_change_ms: u64

Last observed content change, epoch ms.

§tombstone: bool

The source was observed gone.
