Module middleware 

Cross-cutting middleware. Ports the reusable concerns of agent_core/api/: request-id propagation (request_id) and the API latency SLO (latency_slo).

Structs

RateLimiter

Shared fixed-window request limiter used by the host middleware stack.

Constants

SLO_BUDGET_MS

The API latency budget (p95 ≤ 1s is the product line). Requests over this are logged at warn so a regression surfaces without a profiler.

Functions

latency_slo

Time each request, attach x-response-time-ms, and warn past the SLO budget.

rate_limit

Rejects requests beyond the configured fixed-window rate.

request_id

Mint (or honor a client-supplied) request id, stash it in extensions for handlers, and echo it on the response.
