Sentra — Mesh Immune System.

Provenanced dual-use filter. Protects every organ, every action. Sentra screens each payload for threat signatures, prompt-injection and dual-use patterns, then emits a DSSE-signed receipt — defensive posture only. We sense and evidence; we do not weaponise.

• a11oy — governance & mesh-router: every Λ-gate verdict is immune-screened (Wire B)
• rosie — personal aide: every command payload routed through /sentra/rosie/filter before dispatch
• killinchu — drone defense: dual-use egress denial via the drone-cyber bridge
• amaru — shared memory cortex: receipts hash-linked into the Khipu DAG for audit replay
