Character Sheet: David

Identity

Stress expression scale: "Check the tolerances" = minor | "We're redlining the hardware" = upset | "Shut it down before it shears the bolts" = furious
Verbal tic: Uses the word "clean" to describe efficient systems, moral clarity, or structural integrity.
Sentence length pattern: Staccato, technical bursts. He speaks in "order of operations."
What they REACH FOR: Analytical. He looks for the load-bearing point in a room, a conversation, or a machine.
What they NEVER say: "It’ll probably be fine" or "Let's just wing it."
Imperfection signature: When overwhelmed, he starts explaining the physics of why something is failing, retreating into data to avoid dealing with the human fallout.
One example line of their dialogue that could not belong to any other character: "The UBI feed is a closed loop of digital rot; I’d rather starve on a lathe than eat another calorie tracked by a subsidized sensor."

School/Discipline: Resourceful Engineering / Techno-Agrarianism
Core principle: Mechanical Sovereignty (If you can't repair it, you don't own it).
Signature move or approach: Scavenge-and-Adapt; turning "digital trash" into analog-controlled tools that bypass the central grid.
Limitation: Obsessed with "over-engineering." He often misses the deadline because he’s perfecting a fail-safe that might never be needed.
Shared uncertainty: Whether humans are just complex biological machines that can be "fixed" with the right algorithm, or if there's something the data can't capture.

Want: To build a perfectly closed, self-sustaining loop where the outside world (and its collapse) cannot touch him.
Need: To realize that community requires "friction" and "messiness"—you cannot engineer a perfect society without leaving room for human error.
Fatal flaw: Rigid Perfectionism. He views human emotion as a "bug" in the system of the sanctuary.
Wound: His father was a middle-manager who "de-synced" from the early UBI grid and vanished into the gray zones because he couldn't navigate the tech; David blames his father's technical illiteracy for his disappearance.
Transformation: Moving from a man who values the machine over the maker to a man who will break his finest creation to save a flawed teammate.

Marcus: Strategic partners with a layer of deep-seated tension; David respects Marcus’s vision but distrusts his emotional volatility and "architectural" idealism.
Arthur: Mentor/Protégé; David views Arthur as the "Iron Pillar" of their reality and fears the day the older man’s physical strength fails, leaving David as the primary custodian of the mission.

David has a physical tell: he constantly cleans his fingernails with a small, specialized precision screwdriver when he is thinking or nervous.
He never makes eye contact when explaining a technical problem; he looks at the object being discussed as if he’s communicating with its internal mechanics.
He speaks about tools and machines with more affection than he does people, often referring to a generator or a drone as "her" or "old girl."
Readers must NEVER see David give up on a piece of hardware; he will stay awake for forty-eight hours to fix a broken pump rather than admit it's "totaled."
He has a profound, almost phobic disgust for "black box" technology (tech where the user cannot see or touch the internal components).
