The criterion

Frozen at issue

Hit if the currency's peak rate against USD inside the window exceeds the issue-day reference (0.735113) by at least 1.16%. Peak, not endpoint: a devaluation that retraces still happened.

The resolver is external — fx_rates (daily USD reference rates) — and the daily snapshot of this call in ledger-snapshots/ carries GitHub's timestamps. Diff any two dated files to verify nothing above moved after 2026-08-27.
