Adds a Go subsystem alongside the existing Python FastAPI service so
bootnode can fold into `superbase` per HIP-0106. The Python service in
`api/bootnode/` stays untouched.
What landed:
- `schema/bootnode.zap` — public typed surface (chains, RPC, tokens,
NFTs, transfers, smart wallets, ERC-4337, gas, webhooks, fleets,
nodes, usage). No `.capnp` anywhere — ZAP only, per brand policy.
- `zap/gen/` — hand-rolled Go bindings that match what `zapc generate`
emits, so `go build` works without zapc installed locally.
- `api/mount.go` — the HIP-0106 contract:
func Mount(r chi.Router, deps Deps) error
mounts every FastAPI-parity route group through `api/handlers/`.
- `api/deps.go` — cross-subsystem ZAP client interfaces (IAM, KMS,
Base, O11y, Commerce). No business logic, no hard imports — keeps
the Bootnode module independent of sibling subsystems until they
ship their typed clients.
- `api/handlers/` — 149 chi routes mounted (Python has 150). Each
handler body is a 501 stub with a `TODO(bootnode-port)` pointing at
the Python file + symbol to port.
- `api/middleware/` — IAM-backed auth, OTEL-friendly telemetry,
per-org rate limit (stub).
- `api/store/` — per-tenant SQLite access via `deps.Base.Open(orgID,
"bootnode")` per HIP-0302.
- `api/web3/` — chain registry + RPC pool surface (production version
prefers luxfi/* over upstream go-ethereum).
- `cmd/bootnode/main.go` — standalone shim; same `api.Mount` superbase
calls in production.
- `docs/PYTHON_TO_GO_PORT.md` — endpoint-by-endpoint port map.
Build: `go build ./...` and `go vet ./...` clean. Standalone shim
smokes 200 on /health, /ready, /v1/chains; 401 on auth-required
endpoints with no JWT; 501 on every TODO route.
Out of scope (not in this commit):
- Handler bodies (Phase 2 — porting in RPC → tokens → NFTs → ...
priority order).
- superbase wiring (lands when the superbase repo opens its main).
- Python service removal (stays until handlers reach prod parity).
