Same names. One side ships. The line is what's load-bearing. Everything above it is live; everything below looks alive but isn't.
Read it once and the confusion that cost you hours becomes one glance:
• Two things are named "old." The old safety-check sits on the live highway — load-bearing, don't touch. The old producer is across the line in the ghost town — safe to delete. Same word, opposite side.
• The tests failed because the cert drove across the line and read il-build (residue) instead of il-deploy (live). That red arrow is the whole bug.
• Three "genome"s — one lives up top, two are dead below. The dashed lines are the look-alikes; the side tells you which is real.
Built on the research: stable hand-laid positions (nothing moves) · live vs. dead by contrast, not position (the ghost town recedes) · landmarks at the forks where look-alikes split · the line encodes the one truth that matters — load-bearing or not.
