Enum Checkpoint 

pub enum Checkpoint {
    AfterMs(i64),
    AfterRuns(u32),
    AfterGrains(u32),
}

When an applied recommendation is re-measured — one checkpoint of the Verify gate’s schedule, in the unit the deployment actually counts in.

Three units, because deployments count differently and a fixed one makes the gate inert everywhere else. A service evaluated nightly counts time (after_ms). A benchmark or a CI harness counts graded runs (after_runs): “measure at the next evaluation after the apply”, however long that takes on the clock. A chat agent counts turns (after_grains): “after fifty more grains”. The default schedule stayed ms-only for a year and was measured, on PAST-Bench, to fire exactly zero verdicts across 78 governed runs — a family finishes in seven minutes and the first checkpoint was a day away (crates/areev-bench/PERSIST.md).

On the wire a bare integer is milliseconds, so every policy, metric snapshot and state blob written before this type existed reads back unchanged, and an all-ms schedule still serializes as [86400000, …].

Variants

AfterMs(i64)

Elapsed time since the apply.

AfterRuns(u32)

Evalset runs journaled since the apply. Only an evalset: metric can count these; on any other metric the checkpoint never comes due.

AfterGrains(u32)

Grains written since the apply — the loop’s own notion of “activity”.

Implementations

impl Checkpoint

pub fn label(&self) -> String

The label a person reads: 1d, 12h, 3 runs, 50 grains.

pub fn as_ms(&self) -> Option<i64>

The ms value when this is a time checkpoint — what legacy consumers of OutcomeResult::horizon_ms read.

Trait Implementations
