Function TestSystemPromptFitsFixedSystemReservation

internal/tui/tui_test.go:74–83

TestSystemPromptFitsFixedSystemReservation pins ctx.FixedSystem against the embedded prompt. Grow the prompt past the reservation and Pack over-allocates to history on small-ctx profiles, so the next request exceeds the server's limit and 400s (or is silently truncated). On failure, raise ctx.FixedS

// to history on small-ctx profiles, so the next request exceeds the server's
// limit and 400s (or is silently truncated). On failure, raise ctx.FixedSystem;
// don't loosen the assertion.
