Each of these leads with the constraint rather than the stack. Anyone can list technologies; the constraint is what tells you whether someone thinks about your problem the way you need them to.

All case studies
ColdDeck
A rule pack, not a model
Prospect scoring where every point traces to the page that produced it, and a human approves every email before it sends. Demonstrates all four commitments at once.
agentic-ai
Agents that stop before they change anything
Characters as folders of plain files — hand-editable, diffable — with agents that halt for approval before writing. Plus a deployment model most teams miss.
DripDeck
Two clocks
Scheduled publishing where the machine never needs to be awake at the right moment, and days it was off self-heal on the next run.
