POST /api/v1/decide
Status: stub. Day 3 deliverable.
Evaluates a policy against an input on the synchronous fast path. SLA: p95 ≤ 10 ms, p99 ≤ 30 ms, CPU budget ≤ 40 ms.
If a deterministic decision cannot be produced (LLM intervention
required, or the rule chain matched a fallback), the response is
ESCALATE_TO_QUEUE and the work is handed off to the async deep path
(architecture/decision-engine).
