1. Reverse Decontamination so its free face accepts Foundry's blue-double and its other face emits amber-single—the exact inverse pair the player observed earlier. Under [Mechanical Interfaces And Opening Quantities](/Hold%20The%20Flood/Mechanical%20Interfaces%20And%20Opening%20Quantities), R26's mechanical selector and final detent work without diagnostic power; sending the confirming pulse still requires current power/input. This machine state persists.
2. On an arrangement where Decontamination's blue-accepting face is physically adjacent to Foundry's blue-emitting face, latch them. A known transformation identifies a useful face pairing; it does not guarantee when the shifting station will offer that exact orientation.

3. Join the group's amber-single face to Imaging Exchange, a rare bridge whose other face can emit red-triple.

3. Join the group's amber-single face to Imaging Exchange, the fixed **A→R** bridge; its other face emits red-triple only when a current powered diagnostic pulse actually reaches the A input.
4. When that growing group later meets Archive's red-triple receiving face, latch it. Walk from Foundry through Decontamination and Imaging into Archive.
5. Send a local diagnostic pulse through the new path to verify that the chosen converter states behave as predicted. This is useful evidence and troubleshooting, not a second condition for geometric completion.
