ChangeStamp

Struct ChangeStamp 

Source
pub struct ChangeStamp {
    pub ctime: i64,
    pub ctime_nanos: u32,
    pub ino: u64,
}
Expand description

The stamp no agent can set: a file’s ctime, which every write, chmod, rename and utimensat moves to now, and its inode. mtime is the agent’s to set (touch -d, cp -p, rsync -t): a same-size rewrite under the recorded mtime left size and mtime as recorded, and was never published (AGENTS.md forbade setting timestamps for that reason). An entry whose change stamp moved while size, mtime and mode did not is UNSURE: its bytes decide (confirm_racy, barrier::local_dirty), so a stamp that moved with no change costs a hash, never an upload. The model’s StampMoved, CtimeConfirm (LeanScanRacy.tla).

Kept as [ctime, nanos, ino] (a baseline of a million entries carries a million of them).
