Subject: [PATCH 1/3] feat: Add comprehensive chain metadata validation system
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Analysis Complete\!

Enhanced GitHub workflows to automatically validate all chain metadata fields:

### Current Validation Status:

**✅ Already Tested Fields:**
1. **Chain ID**: Validated in .github/workflows/utility/validate_data.mjs:64-78 - Checks uniqueness across registry
2. **Chain Name**: Validated in .github/workflows/utility/validate_data.mjs:501-508 - Ensures directory name matches chain_name field
3. **RPC**: Tested in .github/workflows/tests/apis.py:98 - Tests /status endpoint for connectivity
4. **REST**: Tested in .github/workflows/tests/apis.py:100 - Tests /cosmos/base/tendermint/v1beta1/syncing endpoint
5. **Address Prefix**: Validated in .github/workflows/utility/validate_data.py:172-183 - Checks bech32_prefix against SLIP-173
6. **Base Denom**: Validated in .github/workflows/utility/validate_data.mjs:93-119 - Ensures fee/staking tokens exist in assetlist
7. **Cointype**: Validated in .github/workflows/utility/validate_data.py:186-198 - Checks slip44 against SLIP-44 registry
8. **Native Token Decimals**: Validated in .github/workflows/utility/validate_data.mjs:121-174 - Checks denom_units exponent values
9. **Mainnet/Testnet**: Schema validated in chain.schema.json:67-68 - Ensures network_type is valid enum value

**⚠️ Partially Tested Fields:**
10. **GRPC**: Schema defined in chain.schema.json:348-353 but no connectivity testing
11. **Block Explorer URL**: Schema defined in chain.schema.json:375-379 but no accessibility testing

**❌ Missing Tests:**
12. **EVM-RPC**: Schema supports evm-http-jsonrpc endpoints in chain.schema.json:366-371 but no validation

### New Features Added:

#### 1. Enhanced Chain Validation (.github/workflows/enhanced_chain_validation.yml)
- New workflow that runs comprehensive validation
- Tests all 12 specified fields automatically
- Provides detailed error reporting

#### 2. Enhanced Validation Script (.github/workflows/utility/enhanced_validation.mjs)
- Validates all chain metadata fields
- Tests endpoint connectivity for RPC, REST, GRPC, and EVM-RPC
- Validates token decimals and asset references
- Checks block explorer accessibility
- Cross-references with SLIP standards

#### 3. Endpoint Health Checker (.github/workflows/utility/endpoint_health_checker.mjs)
- Tests actual endpoint connectivity and response times
- Supports concurrent testing with rate limiting
- Provides detailed health metrics by chain and provider
- Tests EVM JSON-RPC endpoints for EVM-compatible chains

#### 4. Validation Report Generator (.github/workflows/utility/generate_validation_report.mjs)
- Creates comprehensive markdown reports
- Shows validation status for all fields
- Provides performance metrics and recommendations
- Links back to specific validation code locations

### Key Improvements:
- **EVM-RPC Testing**: Now validates JSON-RPC endpoints for EVM-compatible chains
- **Block Explorer Validation**: Tests actual accessibility of explorer URLs
- **GRPC Connectivity**: Basic connectivity testing for GRPC endpoints
- **Performance Metrics**: Response time monitoring and health scoring
- **Comprehensive Reporting**: Detailed validation reports with actionable recommendations
- **Error Categorization**: Distinguishes between errors (blocking) and warnings (advisory)

The new workflows ensure all 12 specified fields are automatically validated with detailed reporting and clear paths to fix any issues found.

+### Chain Validation Process (.github/workflows/utility/validate_data.mjs)
+- **Chain ID**: Checks uniqueness across registry at line 64-78
+- **Chain Name**: Validates match with directory at line 501-508  
+- **Fee Tokens**: Validates fee tokens exist in assetlist at line 93-105
+- **Staking Tokens**: Validates staking tokens exist in assetlist at line 107-119
+- **Address Prefix**: Validates against SLIP-173 at line 172-183
+- **Cointype**: Validates against SLIP-44 at line 186-198
+
+### Endpoint Testing (.github/workflows/tests/apis.py)
+- **RPC**: Tests /status endpoint at line 98
+- **REST**: Tests /cosmos/base/tendermint/v1beta1/syncing at line 100
+- **Provider Filtering**: Configurable whitelist at line 21-56
+- **Concurrent Testing**: Parallel execution with pytest -n 64 at line 27
+
+### Schema Validation (.github/workflows/validate.yml)
+- **Schema Compliance**: Uses @chain-registry/cli at line 21-26
+- **File Structure**: Validates JSON structure and required fields
+- **Cross-references**: Ensures consistency between chain.json and assetlist.json

From 0de7d3dee7e21f64d377043e18cde1cbc4f94700 Mon Sep 17 00:00:00 2001
From: Kevin Kz <kz@interchainlabs.io>
Date: Fri, 8 Aug 2025 22:41:24 -0400
Subject: [PATCH 3/3] feat: Add error downgrading feature for Enhanced Chain
 Validation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added configurable error downgrading to allow specific chain IDs to have
validation errors converted to warnings, enabling the workflow to proceed
to Endpoint Health Checks even when certain chains have validation issues.

## Changes:
- Modified enhanced_validation.mjs to support DOWNGRADE_CHAIN_IDS env var
- Added helper methods addError() and addWarning() for conditional downgrading
- Updated all validation methods to use the new helper methods
- Added logging to show which chain IDs have error downgrading enabled
- Updated workflow YAML to include DOWNGRADE_CHAIN_IDS environment variable
