Inline dispatch — no goroutine + channel + select per request; config moved from RWMutex to an atomic copy-on-write snapshot. Single dispatch 3.7 µs → 1.0 µs, 25 → 18 allocs (Apple M3), faster than a hand-rolled encoding/json dispatcher.
DoS-safe batch defaults (DefaultMaxBatchSize = 100, bounded concurrency).

Spec compliance

Notifications (execute, no response), raw byte-exact structs.ID (no float64 rounding), -32700 parse errors, per-entry batch decoding, whitespace tolerance.

Server API

Middleware (Use), per-method timeouts (WithTimeout), OpenRPC 1.3.2 generation from the introspectable registry, observability hook (SetObserver).

Transports

jsonrpchttp (net/http) and jsonrpcws (WebSocket, built on coder/websocket) with server push.
Fiber v2/v3 adapters as separate nested modules so Fiber/fasthttp stay out of the core go.mod.

Clients

Caller/CallResult[R] and batch CallBatch/BatchResultAs[R] over both HTTP and WebSocket, with id correlation and streamed batch decoding.

json/v2 readiness

All generic JSON routes through one internal/codec seam; the switch to encoding/json/v2 (≈ Go 1.27) is a one-file change. Still builds on Go 1.25+ with no build flags — no behavior change.
