zeekay 35b62a9b86 The CORS test asserts the route was reached
It checked headers only. A middleware that answered instead of chaining would
set every header the file inspects and still be broken, and all three tests
would have passed — which is the shape of assertion this repo has been finding
elsewhere all day.

Verified by mutation: replacing the chain call with a bare return fails two of
the three, and putting it back passes.

zip middleware

Generic middleware for the zip framework. Auth-specific middleware (JWT validation, identity-header stripping) lives in github.com/hanzoai/gateway/middleware — see "Why auth lives in gateway" below.

Available middleware

Name Purpose
Recover() panic → JSON 500
Logger(luxlog.Logger) request log via luxfi/log
RequestID() X-Request-Id propagation
Timeout(d) per-request ctx deadline
MaxBody(n) request size limit
CORS(opts) standard CORS
RateLimit(opts) per-key token bucket
Telemetry(o11yClient) OTel span + request metrics

Why auth lives in gateway

JWT validation + identity-header minting are the responsibility of the gateway subsystem (per HIP-0106). Other subsystems mounted inside the unified cloud binary trust the gateway-minted X-Org-Id header and do NOT re-validate JWTs themselves — re-running JWT validation per-subsystem is wasteful and risks divergent validation rules.

Subsystems that need to ASSERT the request was gateway-minted import github.com/hanzoai/gateway and call gateway.AssertGatewayMinted(c).

Pipeline order

Recommended order for a service that mounts zip behind hanzoai/gateway:

app.Use(
    middleware.Recover(),                // 1. always first
    middleware.RequestID(),              // 2. mint request id
    middleware.Logger(app.Logger()),     // 3. log with request id
    middleware.Telemetry(o11y),          // 4. metrics
    middleware.RateLimit(rlCfg),         // 5. limit
    middleware.CORS(corsCfg),            // 6. last — close to response
)

JWT validation + identity-header stripping/minting is owned by the gateway subsystem; see github.com/hanzoai/gateway/middleware.
