Records that 18c.1 ran zero-surprise (mechanical recursion at ~10 sites across 6 files), the future-work seam in codegen for 18c.3 is a single line (emit one rc_inc call before returning the inner SSA reg), and 18c.2's linearity check should start as 'green for borrow_own_demo' since that fixture's shape is exactly what the check needs to accept.
