Why Beside is the only allowed path

1 · AI-layer interception

Beside is an AI proxy, not just a dumb relay. Every inbound/outbound message passes through an AI-aware layer that can route, classify, escalate, or compose before hitting Twilio.

2 · Cost containment

Beside absorbs Twilio's per-message pricing complexity. One subscription line at the proxy, no per-message Twilio billing leak into agent code.

3 · qi sovereignty

qi owns the Beside chatID and proxy config. Twilio is the carrier — Beside is the surface. If Twilio changes terms or pricing, Beside swaps the backend without rewriting any Exedus code.

4 · No raw endpoints in agent code

No Twilio account SID / auth token in Ezekiel or mac-xen code. The credential surface stops at Beside. Reduces blast radius of any token leak.

Recent operational

2026-05-21 21:21:06 — Bridge-401 v2 fix landed. X-Xen-Token header added to forward_to_beeper(). Auth layer end-to-end verified.
Conference layer degraded — Beside's vendor-side conference audio had 5+ empty-payload status notices 2026-05-21 night. FCC bridge 727-731-8395 PIN 938316741 dial-in may degrade. VVS legs unaffected.
Layer-2 blocker open — omnimind still calls Beeper 2226 HTTP API (retired). Awaits Phase-2 rewrite against Beeper MCP at port 23374. Recon report at ~/.claude/swarm-history/2026-05-21-beeper-2226-to-mcp-23374-recon.md.
