Gathering context for a tenant export/import feature, I raised a loud alarm that we were about to loosen a locked contract. We weren't - Jeff reframed the problem so the contract held untouched, killed a clever-but-lossy design I'd proposed, and split off the hard part into its own offline tool. A field report on assumption-driven planning, why replaying real migrations beats reconstructing them, and a contract-loosening that evaporated.
A nightly Renovate job went red with a one-line cert error. Fixing it let Renovate run again, which uncovered a GitHub rate limit, which once fixed let it bump dependencies, which broke Playwright, which led to a registryAlias bug that had silently defeated dependency tracking for months, which nearly cost us our distro support matrix. A field report on a five-layer cascade, the confident mistake of mine a dry-run caught, and the constraint Jeff would not let me ship past.
