## Summary
- Wire the Frontier `EthPubSub` module into the node's RPC layer,
enabling WebSocket-based `eth_subscribe`/`eth_unsubscribe` support for
`newHeads`, `logs`, and `newPendingTransactions`
- Use Ethereum-style hex (`0x`-prefixed) subscription IDs via
`EthereumSubIdProvider` for client compatibility
- Add Moonwall test suites (adapted from Moonbeam) covering block header
subscriptions, log filtering (by address, topics, wildcards, conditional
parameters), and pending transaction notifications
## Changes
### `operator/node/src/rpc.rs`
- Import and merge `EthPubSub` / `EthPubSubApiServer` into the RPC
module
- Accept `subscription_task_executor` and `pubsub_notification_sinks`
parameters in `create_full()`
- Remove stale commented-out boilerplate
### `operator/node/src/service.rs`
- Clone `pubsub_notification_sinks` and forward it (along with
`subscription_executor`) into the RPC factory closure
- Set `config.rpc.id_provider` to `EthereumSubIdProvider` for
Ethereum-compatible subscription IDs
### `test/moonwall/suites/dev/stagenet/subscription/`
- `test-subscription.ts` — `newHeads`: subscription ID format, block
header field validation
- `test-subscription-logs.ts` — `logs`: basic log notification on
contract deployment
- `test-subscription-logs2.ts` — `logs`: filtering by single/multiple
addresses, topics, wildcards, conditional and combined parameters (8
cases)
- `test-subscription-pending.ts` — `newPendingTransactions`: pending tx
hash notification

## Summary
Reorganizes the test directory structure for better clarity and
maintainability:
- **Rename `test/datahaven/` → `test/moonwall/`**: Clearly identifies
these as Moonwall single-node tests
- **Move `test/framework/` → `test/e2e/framework/`**: Groups e2e test
utilities under a dedicated folder
- **Move `test/suites/` → `test/e2e/suites/`**: Groups e2e test suites
with the framework
- **Add `test/e2e/framework/validators.ts`**: Extracts validator test
helpers from utils into the e2e framework
- **Update documentation**: README.md and E2E_FRAMEWORK_OVERVIEW.md
reflect the new structure
### New Directory Structure
