Pillar 01: Software
Software systems
- Architecture decisions are bounded with explicit interfaces.
- Automation exposes state and fails in predictable ways.
- Release paths include rollback and replay from the start.

Systems
Systems fail when boundaries are implied. Pume keeps ownership, interfaces, and operating rules explicit before velocity increases.

Boundary rules
Explicit ownership.
Measured reliability.
Auditable decisions.
Bridge
Boundaries define what gets measured. The method defines how checks, rollbacks, and review cadence are executed in sequence.
