Start with the stack trace location in @cortexkit/opencode-magic-context/src/tui-compiled/slots/sidebar-content.tsx, especially warning at line 872, and reproduce the crash with magiccontext + AFT on OpenCode 1.18.31. Determine why s().tailHygiene is undefined; done means the TUI no longer crashes in the reported configuration.
