zevron ledger

Report against the held-out Ledger — the benchmark Zevron never trains against.

Synopsis

$ zevron.exe --version

The Ledger is a held-out benchmark that Zevron never trains against — the oracle that catches silently-wrong code. zevron ledger reports how the current registry performs against it.

Curve

zevron ledger curve plots held-out pass-rate and cost per task against registry size, with a flat baseline for the registry turned off:

zevron — ledger

zevron ❯ zevron ledger curve

held-out pass-rate ↑ · cost / task ↓ · registry off stays flat

Use zevron ledger summary for the latest pass-rate and cost as plain numbers.

Flags

Flag	Default	Description
--window	30d	Time window for the report.
--json	off	Emit machine-readable output.

Why held-out

Because the Ledger is never trained against, a number it reports is real capability, not something memorized. That is what makes pass-rate on the Ledger meaningful — and what the registry moves. See the Registry and the trust model.
