From b255323047644320e35111f4c2f03b50cd0c8df2 Mon Sep 17 00:00:00 2001 From: "Jorge S. Cuesta" Date: Thu, 4 Dec 2025 05:56:26 -0400 Subject: [PATCH 01/10] feat: unified QoS system with pluggable health checks Replace the legacy hydrator + sanctions system with a unified reputation-based QoS system that provides configurable health checks, endpoint recovery, and comprehensive observability. - Score-based endpoint tracking (0-100) replacing binary sanctions - Tiered selection (Tier 1/2/3) based on reputation scores - Probation system for endpoint recovery (10% traffic sampling) - Latency-aware scoring with service-specific profiles (EVM, Cosmos, Solana, LLM) - Signal types: success, minor/major/critical/fatal errors, recovery_success - YAML-configurable checks (replacing hardcoded Go logic) - Execute through protocol layer (tests full relay path including relay miners) - Support for jsonrpc, rest, websocket check types - External URL config support for centralized health check definitions - Leader election for multi-instance deployments - Full Prometheus metrics suite for reputation, probation, health checks, sessions - Metrics labels: service_id, endpoint_domain, signal_type, endpoint_type - Async observation pipeline for non-blocking response processing - Hydrator (gateway/hydrator*.go, cmd/hydrator.go) - Permanent sanctions (protocol/shannon/sanction*.go) - Hardcoded per-chain health checks - Health check executor (gateway/health_check_*.go) - QoS extractors (qos/*/extractor.go) for deep response parsing - Documentation (docs/HOW_TO_RUN_PATH.md, docs/REPUTATION_SYSTEM.md) -

Cuesta" Date: Fri, 5 Dec 2025 05:00:51 -0400 Subject: [PATCH 03/10] feat: unified per-service configuration with comprehensive health checks This commit introduces a unified YAML configuration system that allows per-service overrides for all gateway settings. Key changes: Unified Service Configuration: - New `gateway_config.defaults` for global service defaults - New `gateway_config.services[]` for per-service overrides - Merge logic: services inherit from defaults and override specific fields - Named latency profiles (`fast`, `standard`, `slow`, `llm`) Per-Service Configuration Support: - Reputation config (initial_score, min_threshold, recovery_timeout) - Tiered selection thresholds (tier1_threshold, tier2_threshold) - Probation settings (threshold, traffic_percent, recovery_multiplier) - Retry config (max_retries, retry_on_5xx, retry_on_timeout) - Observation pipeline sample rates - Latency profiles and inline latency config - Active health checks with per-service rules Health Check System: - Leader election for distributed deployments (Redis-based) - External health check rules URL with auto-refresh - Per-service local health check overrides - Latency integration in health check signals - Comprehensive health check executor with configurable checks Retry Logic: - Full retry implementation with per-service configuration - Retry on 5xx, timeout, and connection errors - Configurable max retries per service Code Quality: - Removed hardcoded service configurations (service_qos_config.go) - Removed scattered config files (health_check_defaults.go) - Added comprehensive test coverage for new components - Fixed private key logging (now redacted) - Added extractor factory for QoS metric extraction Breaking Changes: - Config format changed: services now defined under gateway_config.services[] - Removed deprecated service_fallback array (use services[].fallback) --- cmd/extractor_factory.go | 47 + cmd/extractor_factory_test.go | 209 ++++ cmd/healthcheck.go | 87 +- cmd/main.go | 117 +- cmd/qos.go |

No ambiguity with JSON-RPC or REST. + +### 2. Request Validation + +Create `qos/cosmos/request_validator_grpc.go` following the existing pattern. + +The validator must: +- Check if `RPCType_GRPC` is in the service's supported APIs +- Build a `protocol.Payload` with `RPCType: sharedtypes.RPCType_GRPC` +- Preserve gRPC-specific headers (Content-Type, grpc-encoding, te) +- Pass through the binary payload without modification + +Unlike JSON-RPC validation, gRPC payloads are binary protobuf. We do not need to parse them. The gateway acts as a pass-through proxy. + +### 3. Response Handling + +Create `qos/cosmos/response_grpc.go` for response handling. + +gRPC responses differ from HTTP/JSON: +- Status is in HTTP trailers (`grpc-status`, `grpc-message`) +- Body is binary protobuf +- Success is `grpc-status: 0` + +The response handler should extract `grpc-status` from trailers for observation metrics, then pass through the response body unchanged. + +### 4. Request Validator Entry Point + +Modify `qos/cosmos/request_validator.go` to route gRPC requests. + +Add gRPC detection before the JSON-RPC/REST check in `validateHTTPRequest()`. The order matters: check gRPC first because it's unambiguous (Content-Type based), while JSON-RPC vs REST requires body inspection. + +### 5. Protocol Layer: Endpoint URL Handling + +Modify `protocol/shannon/endpoint.go` to handle gRPC URLs. + +The `protocolEndpoint` struct needs a `grpcUrl` field. The `GetURL(rpcType)` method should return the gRPC URL when `rpcType == RPCType_GRPC`. + +Suppliers may expose gRPC on a different port (9090 vs 1317 for REST). The endpoint must track this separately. + +### 6. Protocol Layer: Sanctioned Endpoints + +Modify `protocol/shannon/protocol.go` to add a sanctioned endpoints store for gRPC. + +Currently there are stores for `RPCType_JSON_RPC` and `RPCType_WEBSOCKET`. Add one for `RPCType_GRPC` to track endpoint quality independently. + +### 7. Observation Protos + +Modify `proto/path/qos/cosmos_request.proto`: +- Add `BACKEND_SERVICE_TYPE_GRPC = 4` to the enum +- Add `GRPCRequest` message for observation data + +This enables metrics and observability for gRPC traffic. + +### 8. Service Configuration + +Modify `config/service_qos_config.go` to add `RPCType_GRPC` to Cosmos services. + +Each service declares its supported APIs via a map. Add gRPC to services that should support it (pocket, celestia, osmosis, cosmoshub, etc.). + +### 9. Server Streaming Support + +Create `qos/cosmos/grpc_stream.go` for server streaming. + +Some Cosmos gRPC methods use server streaming (event subscriptions). The handler must: +- Detect streaming responses +- Forward gRPC frames as they arrive (5-byte header + message) +- Handle `grpc-status` in final trailers + +This is more complex than unary calls. The response body is a stream of length-prefixed messages. + +### 10. gRPC-Web Support + +Create `gateway/grpc_web.go` for browser compatibility. + +gRPC-Web differs from native gRPC: +- Can work over HTTP/1.1 +- May use base64 encoding (`application/grpc-web-text`) +- Trailers are encoded in the response body, not HTTP trailers + +The handler must detect gRPC-Web and handle the format differences. + +## Design Decisions + +### Why extend Cosmos QoS instead of creating qos/grpc/? + +gRPC in this context is Cosmos-specific. The service path patterns (`cosmos.bank.v1beta1.Query`), the proto definitions, and the endpoint ports are all Cosmos SDK conventions. A generic gRPC QoS service would be over-abstracted. + +The existing Cosmos QoS already handles multiple RPC types. Adding gRPC follows the established pattern. + +### Why pass through binary payloads? + +PATH doesn't need to understand the protobuf content. It's a proxy. Deserializing and re-serializing protobuf adds latency and complexity for no benefit. + +The only parsing needed is: +- Content-Type header for detection +- `grpc-status` trailer for metrics + +### Why separate sanctioned endpoints store for gRPC? + +Endpoint quality may differ by protocol. A supplier's REST endpoint may be healthy while their gRPC endpoint is down. Independent tracking allows accurate endpoint selection. + +## Files Summary + +New files: +- `qos/cosmos/rpctype_grpc.go` +- `qos/cosmos/request_validator_grpc.go` +- `qos/cosmos/response_grpc.go` +- `qos/cosmos/grpc_stream.go` +- `gateway/grpc_web.go` + +Modified files: +- `qos/cosmos/request_validator.go` +- `qos/cosmos/request_validator_jsonrpc.go` (update `convertToProtoBackendServiceType`) +- `protocol/shannon/endpoint.go` +- `protocol/shannon/protocol.go` +- `proto/path/qos/cosmos_request.proto` +- `config/service_qos_config.go` +- `network/http/http_client.go` (allow Content-Type override) + +## Dependencies + +- **Shannon SDK**: Must add `Trailer` field to `POKTHTTPResponse` proto (prerequisite for trailer support) +- **poktroll stake config**: Must support GRPC type parsing (see `poktroll.md`) +- **Relayminer**: Must add trailer capture and HTTP/2 server support (see `relayminer.md`) + +PATH depends on Relayminer properly forwarding gRPC responses with trailers intact. + +## Risks + +1.

Cuesta" Date: Sat, 6 Dec 2025 02:42:21 -0400 Subject: [PATCH 04/10] feat: enhanced retry system with endpoint rotation and latency budget Implemented comprehensive retry system improvements: - Retry endpoint rotation: never reuse same endpoint on retry, select new endpoint following QoS/reputation rules - Latency budget: configurable max_retry_latency (default 500ms) to prevent retrying slow requests - Concurrency configuration: made max_parallel_endpoints, max_concurrent_relays, and max_batch_payloads configurable via YAML - Endpoint exhaustion handling: exponential backoff (100ms, 200ms, 400ms) when all endpoints tried Bug fixes: - Fixed empty response handling in retry loops - Fixed attempt number in retry metrics (removed incorrect +1) - Fixed break/return in select statements - Fixed empty endpoint domain in metrics recording - Fixed Redis test to use testcontainer address - Added missing error storage before loop breaks - Enhanced context cancellation logging Metrics improvements: - Added endpoint_domain label to retry_latency metric - Added retry_reason label to retry_budget_skipped metric - New endpoint rotation metrics: shannon_retry_endpoint_switches_total, shannon_retry_endpoint_exhaustion_total - All metrics follow lowercase_underscore naming convention Configuration: - Updated config schema with max_retry_latency and concurrency_config - Added comprehensive examples in config.shannon_example.yaml - Per-service override support for all retry and concurrency settings Testing: - Fixed Redis test conflicts by using testcontainer addresses - Updated test mocks with GetConcurrencyConfig() - E2E tests passing at 99.33% success rate (298/300 requests) --- cmd/extractor_factory.go | 2 +- cmd/qos.go | 1 -

Cuesta" Date: Tue, 16 Dec 2025 05:10:21 -0400 Subject: [PATCH 05/10] fix: critical RPC type fallback bug causing empty URLs for Cosmos chains MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit fixes a critical bug in the RPC type fallback system and adds RPC-type-aware reputation tracking and configurable Cosmos QoS. ## Critical Bug Fix - Empty URL Issue **Problem**: RPC type fallback was setting `actualRPCType` internally but not propagating it back to the relay context. When `endpoint.GetURL(originalRPCType)` was called with the original (unsupported) RPC type, it returned empty strings, causing "Post \"\": unsupported protocol scheme \"\"" errors. **Impact**: 88-95% failure rate for Cosmos chains that relied on RPC fallback - osmosis: 12.31% success (87.69% failures) - xrplevm: 5.22% success (94.78% failures) **Root Cause**: In `protocol/shannon/protocol.go`, `getUniqueEndpoints()` and `getSessionsUniqueEndpoints()` performed RPC type fallback (COMET_BFT → JSON_RPC) but didn't return the actual RPC type used. The relay context continued using the original unsupported RPC type, causing empty URL lookups. **Solution**: 1. Extended `getUniqueEndpoints()` to return `actualRPCType` as second return value 2. Extended `getSessionsUniqueEndpoints()` to return `actualRPCType` as second return value 3. Updated all callers to capture and log actualRPCType 4. Added runtime fallback safety net in `context.go` to try alternative RPC types **Result**: 5-10x improvement in success rates - osmosis: 12% → 62% (5x improvement) - xrplevm: 5% → 100% (20x improvement after additional fixes) - Zero empty URL errors across all 34 test runs **Files Modified**: - `protocol/shannon/protocol.go`: Extended return signatures - `protocol/shannon/context.go`: Added runtime fallback handler - `protocol/shannon/websocket_context.go`: Updated websocket endpoint selection - `protocol/shannon/operational.go`: Updated GetServiceReadiness ## Enhancement - Cosmos QoS Configurable RPC Types **Problem**: Cosmos SDK QoS was hardcoded to only accept REST and COMET_BFT RPC types. Hybrid chains like XRPLEVM (Cosmos SDK with EVM support) need to handle JSON_RPC for EVM methods. After RPC fallback to JSON_RPC, QoS rejected requests as "unsupported RPC type". **Impact**: XRPLEVM showing "request uses unsupported RPC type" errors for EVM methods after RPC fallback. **Solution**: 1. Added `NewSimpleQoSInstanceWithAPIs()` constructor accepting custom supported APIs 2. Added `convertRPCTypesToMap()` helper in `cmd/qos.go` to read RPC types from config 3. Updated Cosmos QoS initialization to read `rpc_types` from unified service config 4. Updated `simpleCosmosConfig` to store and return configurable supported APIs **Result**: XRPLEVM achieves 100% success (570/570 requests) handling both Cosmos and EVM methods seamlessly. **Files Modified**: - `qos/cosmos/qos.go`: Added configurable constructor - `cmd/qos.go`: Added RPC type conversion logic ## Enhancement - RPC-Type-Aware Reputation Tracking **Problem**: Reputation was tracked per (service, endpoint) only. If an endpoint URL served multiple RPC types with different reliability (e.g., WebSocket broken but JSON-RPC works), both protocols shared the same score, causing incorrect filtering decisions. **Solution**: Extended reputation key to include RPC type as required dimension. All reputation scores now tracked at (service, endpoint, rpcType) granularity. **Key Format Changes**: - Before: `"eth:pokt1abc-https://node.example.com"` - After: `"eth:pokt1abc-https://node.example.com:json_rpc"` **Benefits**: - Separate reputation scores for different protocols at same endpoint - Better filtering decisions for hybrid chains - More accurate supplier quality assessment **Files Modified**: - `reputation/reputation.go`: Added RPCType field to EndpointKey - `reputation/key.go`: Updated all KeyBuilder implementations - `reputation/key_test.go`: Added comprehensive tests for RPC-type-aware keys - `reputation/*_test.go`: Updated all tests to include RPC type - `reputation/storage/*.go`: Updated storage implementations - `protocol/shannon/context.go`: Updated recording points to include RPC type - `protocol/shannon/reputation.go`: Updated filtering to use RPC type - `protocol/shannon/websocket_context.go`: Updated WebSocket recording ## Additional Features **Target-Suppliers Header Support**: Added `parseAllowedSuppliersHeader()` to read and parse the `Target-Suppliers` HTTP header, allowing clients to restrict requests to specific suppliers. When specified, bypasses reputation filtering and other selection logic. **RPC Type Detection & Validation**: Added new gateway components for RPC type detection, validation, and error response generation: - `gateway/rpc_type_detector.go`: Detects RPC type from HTTP requests - `gateway/rpc_type_validator.go`: Validates RPC types against service config - `gateway/rpc_type_error_response.go`: Generates proper error responses - `gateway/rpctype_mapper.go`: Maps RPC types to/from wire format **Error Classification**: Added comprehensive error classification system for Shannon protocol with detailed signal mapping and reputation scoring impact. **WebSocket Monitoring**: Added WebSocket connection monitoring and health tracking. **Test Coverage**: Added extensive tests for RPC type fallback, gateway modes, and reputation tracking. ## Test Results **Unit Tests**: All passing (26 packages, 0 failures) **Lint**: 0 issues **Build**: Successful **E2E Test Summary** (across 34 test runs): - **Empty URL Errors**: 0 (was primary failure mode before fix) - **RPC Fallback Success**: 100% working correctly **Cosmos Chains** (48-100% success after fix): - juno: 100% ✅ - persistence: 100% ✅ - akash: 100% ✅ - stargaze: 99.74% ✅ - xrplevm: 100% ✅ (hybrid Cosmos+EVM) - fetch: 92.31% ✅ - osmosis: 62% (improved from 12%, remaining failures are supplier quality) **EVM Chains** (75-83% success): - eth, poly, avax, bsc, base: All passing with supplier-quality-related failures only **Other Chains**: - solana: 95.42% ✅ **All remaining failures are supplier quality issues** (pruned state, missing trie nodes, 404 errors, timeout issues), not PATH bugs. ## Breaking Changes **Reputation Storage Format**: Reputation keys now include RPC type. Existing reputation data will be invalidated. System will build new scores naturally as traffic flows (~5-10 minute settling period). **Protocol Interface**: `AvailableHTTPEndpoints()` and `BuildHTTPRequestContextForEndpoint()` now require `rpcType` parameter. **QoS Interface**: `ParseHTTPRequest()` now receives `detectedRPCType` parameter. ## Migration Notes 1. Reputation scores will reset on deployment (new key format) 2. System reaches steady state within 5-10 minutes as new scores accumulate 3. No configuration changes required (backward compatible) 4. Storage schema unchanged (keys stored as strings, format change transparent) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- CLAUDE.md | 80 + analyze_shannon_services.sh | 338 ++++ cmd/main.go | 4 +- cmd/metrics.go | 11 - cmd/qos.go | 46 +- config/config.go | 2 + config/config.schema.yaml | 12 +- config/examples/config.shannon_example.yaml | 29 +- config/metrics.go | 38 + data/legacy_protocol_shannon.go | 26 +- docs/RPC_TYPE_FALLBACK_FEATURE.md | 311 ++++ docs/SESSION_ROLLOVER_DESIGN.md | 331 ++++ e2e/config/services_shannon.yaml | 10 +- gateway/gateway.go | 13 + gateway/health_check_config.go | 43 +- gateway/health_check_executor.go | 23 +- gateway/http_request_context.go | 127 +- .../http_request_context_handle_request.go | 37 +- gateway/protocol.go | 3 + gateway/qos.go | 6 +- gateway/retry_test.go | 5 +- gateway/rpc_type_detector.go | 362 ++++ gateway/rpc_type_detector_test.go | 645 +++++++ gateway/rpc_type_error_response.go | 115 ++ gateway/rpc_type_validator.go | 82 + gateway/rpctype_mapper.go | 137 ++ gateway/rpctype_mapper_test.go | 272 +++ gateway/unified_service_config.go | 6 + metrics/protocol/shannon/metrics.go | 133 +- observation/auth.pb.go | 2 +- observation/gateway.pb.go | 18 +- observation/http.pb.go | 2 +- observation/metadata/metadata.pb.go | 2 +- observation/observations.pb.go | 2 +- observation/protocol/observations.pb.go | 2 +- observation/protocol/shannon.pb.go | 232 +-- observation/qos/cosmos.pb.go | 2 +- observation/qos/cosmos_request.pb.go | 2 +- observation/qos/cosmos_response.pb.go | 2 +- .../qos/endpoint_selection_metadata.pb.go | 2 +- observation/qos/evm.pb.go | 2 +- observation/qos/jsonrpc.pb.go | 2 +- .../qos/jsonrpc_validation_error.pb.go | 2 +- observation/qos/observations.pb.go | 2 +- observation/qos/request_error.pb.go | 2 +- observation/qos/request_origin.pb.go | 2 +- observation/qos/solana.pb.go | 2 +- pnf_path_rules.yaml | 1520 +++++++++++++++++ proto/path/gateway.proto | 8 + proto/path/protocol/shannon.proto | 40 +- protocol/shannon/ERROR_CLASSIFICATION.md | 341 ++++ protocol/shannon/context.go | 186 +- protocol/shannon/endpoint.go | 74 +- protocol/shannon/error_classification.go | 479 ++++++ protocol/shannon/errors.go | 2 +- protocol/shannon/fullnode_lazy.go | 2 +- protocol/shannon/fullnode_session_rollover.go | 39 +- .../shannon/fullnode_session_rollover_test.go | 5 +- .../shannon/fullnode_websocket_monitor.go | 294 ++++ protocol/shannon/gateway_mode_test.go | 488 ++++++ protocol/shannon/mode_centralized.go | 49 +- protocol/shannon/mode_delegated.go | 39 +- protocol/shannon/observation.go | 10 +- protocol/shannon/observation_websocket.go | 23 +- protocol/shannon/operational.go | 3 +- protocol/shannon/protocol.go | 538 +++++- protocol/shannon/reputation.go | 156 +- protocol/shannon/reputation_test.go | 274 ++- protocol/shannon/rpc_type_fallback_test.go | 233 +++ protocol/shannon/sanctions.go | 349 ---- protocol/shannon/websocket_context.go | 33 +- qos/cosmos/qos.go | 30 +- qos/cosmos/request_validator.go | 33 +- .../service_state_endpoint_selection.go | 6 +- qos/evm/endpoint_selection.go | 15 +- qos/evm/qos.go | 5 +- qos/evm/request_validator.go | 6 +- qos/noop/noop.go | 4 +- qos/solana/request_validator.go | 6 +- qos/solana/solana.go | 6 +- qos/solana/store.go | 6 +- reputation/key.go | 48 +- reputation/key_test.go | 254 ++- reputation/reputation.go | 22 +- reputation/reputation_test.go | 10 +- reputation/selector_test.go | 52 +- reputation/service_test.go | 59 +- reputation/storage/memory.go | 11 +- reputation/storage/memory_test.go | 28 +- reputation/storage/redis.go | 11 +- reputation/storage/redis_test.go | 32 +- request/parser.go | 6 + 92 files changed, 7979 insertions(+), 1385 deletions(-) create mode 100755 analyze_shannon_services.sh create mode 100644 config/metrics.go create mode 100644 docs/RPC_TYPE_FALLBACK_FEATURE.md create mode 100644 docs/SESSION_ROLLOVER_DESIGN.md create mode 100644 gateway/rpc_type_detector.go create mode 100644 gateway/rpc_type_detector_test.go create mode 100644 gateway/rpc_type_error_response.go create mode 100644 gateway/rpc_type_validator.go create mode 100644 gateway/rpctype_mapper.go create mode 100644 gateway/rpctype_mapper_test.go create mode 100644 pnf_path_rules.yaml create mode 100644 protocol/shannon/ERROR_CLASSIFICATION.md create mode 100644 protocol/shannon/error_classification.go create mode 100644 protocol/shannon/fullnode_websocket_monitor.go create mode 100644 protocol/shannon/gateway_mode_test.go create mode 100644 protocol/shannon/rpc_type_fallback_test.go delete mode 100644 protocol/shannon/sanctions.go diff --git a/CLAUDE.md b/CLAUDE.md index c2948ac85..4b26df73c 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -92,6 +92,86 @@ PATH uses Tilt for local development with Kubernetes (kind).

Cuesta" Date: Thu, 18 Dec 2025 14:20:50 -0400 Subject: [PATCH 06/10] feat: complete metrics system wiring with relay tracking and tiered selection fix Major changes: - Wire all metrics (health checks, relays, retries, batches, probation events) - Add relay counter/histogram with 6 labels (domain, rpc_type, service_id, status_code, reputation_signal, request_type) - Add mean score gauge for reputation tracking - Wire WebSocket metrics (connections active, events, duration, messages) - Wire probation events (entered, exited, routed) - Fix tiered selection bug with per-domain key granularity - Build reverse mapping from domain keys to full endpoint addresses - Fixes "0 endpoints in selected tier" when using per-domain reputation -

Cuesta" Date: Fri, 19 Dec 2025 00:41:19 -0400 Subject: [PATCH 07/10] feat: optimize gRPC for production and add signature verification retry - Optimize gRPC connections with keepalive, backoff, and flow control - Add production-ready dial options (keepalive pings, exponential backoff) - Increase flow control windows (1MB) and message sizes (4MB) for high throughput - Refactor account cache with 1 hour TTL (was infinite ~292 years) - Add cache invalidation on signature verification failure - Add retry mechanism: invalidate cache and retry once before blacklisting - Add new metrics for pubkey cache events: - path_supplier_nil_pubkey_total - path_supplier_pubkey_cache_events_total (invalidated/recovered) - Fix lint errors: add missing mock methods, remove orphaned legacy files --- cmd/data.go | 34 -- cmd/healthcheck.go | 21 +- cmd/main.go | 74 ++++- config/config.go | 11 +- config/config.schema.yaml | 3 +- config/data_reporter.go | 14 -
