Trust gap
Problem and Why Sigillum Exists
The system that generated a change should not be the only thing approving it. Sigillum exists to solve that trust gap with a paid external receipt.
The trust gap
Autonomous software systems are very good at producing output quickly, but fast output is not the same as safe output. The moment that matters is not when a diff is generated; it is when the caller decides to merge, install, or deploy.
Without an external checkpoint, an agent can generate and approve its own risky behavior. Sigillum breaks that loop by making the caller buy a verification receipt first.
What counts as risky
Sigillum focuses on actions that have a meaningful blast radius in real software workflows.
- Code changes
- Dependency installs
- Deploy actions
- Config changes as a future extension
Why paid proof instead of free suggestions
The paid step matters because it turns verification into an explicit economic decision. A caller can see the quote before spend, apply budget policy, then deliberately buy the receipt.
That makes Sigillum auditable in a way that passive lint-like suggestions are not.
