RFC-0005: Nexus Core function & storage wire surfaces

Abstract

Phase 9 HTTP surfaces for function gateway and Raft KV (management API port, default 7600).

Deploy

POST /v1/functions

{ "tenant": "demo", "name": "add1", "wasm_hex": "...", "memory_mib": 16, "fuel": 5000000 }

Invoke

POST /v1/functions/invoke

{ "tenant": "demo", "function": "add1", "input_hex": "29", "priority": 1 }

Priority ≥ 200 is treated as real-time lane traffic (never shed under CPU saturation).

Scale / logs

• POST /v1/functions/scale { "tenant", "name", "instances" }
• GET /v1/functions/logs

KV

• POST /v1/kv { "key", "value_hex" }
• GET /v1/kv/{key}

Auth

Authorization: Bearer role:name (e.g. admin:ops) — same as Phase 7.

Roadmap (non-normative)

gRPC invoke, event triggers, container image ingest, SQL-over-KV.
