The first few days after Bucky goes
under are spent in data analysis and quality assurance. There's a lot of information in the human mind, after all. Much of it is messy and complicated and stored in structures that are interconnected in unexpected ways. And when it comes to a project like this, something that's never truly been done before with a biological mind versus synthetic structures and artificial intelligence, something that has the highest of stakes, there's no second chance and thus no room for error.
Shuri spends her time focused on the
mission during the first few days, leaving the majority of the data integrity checks to her technical team. She reviews their work at the start and end of each day when she comes to check on her sleeping patient, making corrections to methods and systems and processes where needed. She makes sure that there are two untouched backups of the original digital representation stored safely at all times in case they have to start over. Finally, they're able to confirm that everything is prepared, that the digital representation is not only complete but stable, and that the real work is ready to begin.
Once the mission's done, she turns the weapon prototype and its blueprints over to a few of her most highly-trusted developers for analysis and immerses herself in Bucky's mind. She'd already drafted the initial algorithm, of course, and has spent nearly three months refining it against the initial scans, every additional scan she's done since, the data from the notebooks Bucky'd kept and the memories he'd written down. She doesn't think it'll take too long to finish it.
It takes weeks.
She ruins multiple copies of the digital representation in the first two weeks while testing the algorithm against it - first in simulation and then in practice. It's the practical part that turns out to be problematic. During the first few tests, her code destroys HYDRA's trigger programming as intended, but then also devours the memories attached to it and proceeds to spread like a virus through everything it can reach. The next series of tests fails to fully eliminate the triggers, and post-implementation simulation reveals that the damaged programming, if not fully removed, will destabilize the mind entirely over time, leaving the subject lost to madness or dementia or both. Shuri refuses to allow any of it. Even the possibility is too much. Nothing must be left to chance. Nothing of harm must be allowed to remain.
Meanwhile, silent in the cryo chamber, Bucky sleeps on.
They're into the third week before the first test is passed. All work comes to a halt in the lab as they stare at the displays. No one dares breathe until the test is repeated. When the second series of results flashes up on screen, showing success across every aspect, the lab explodes in cheers. Instead of becoming easier, Shuri's work becomes even more painstaking and demanding, as she sets out to ensure the smallest nuances are fully refined. She creates additional copies and runs the algorithm against them under high-strain conditions. She practices transitioning the new digital copy from server to server to server, trying to eliminate any and all possibility of data loss during transfer.
At the end of the third week, she sends for T'Challa.
____________________The first thing he's aware of is the cold. This kind of cold he knows all too well. It chills all the way to the bone, pinning him in place with frigid air around him and a cold surface under him. He's too cold even to shiver. Bucky can't move or speak, or do anything at all other than lie still and quiet, listening to the soft hissing sound that's the only thing he can hear.
He drifts in and out of awareness for a while as the light around him gets brighter and the temperature starts to rise. It's not until there's a loud 'click' and the hum of the cryo chamber opening that he finally opens his eyes.
