Thanks for the detailed postmortem. This incident highlights the risks of uneven validator upgrades and assumptions around dispute handling. Key takeaways: ensure all validators upgrade before enabling critical runtime features, avoid relying solely on off-chain disablement, and improve resilience under load. Great to see fixes already implemented and more robust testing planned. The ecosystem’s response was fast and transparent—valuable lessons for all parachain teams.
