Replace the circuit breaker state machine with a simpler consecutive-failure counter and cooldown approach. N failures in a row, skip for M seconds, then retry.
- Fix getBlockBeforeTime signature to match GetBlockBeforeTimeParams - Fix AlchemyAssetTransferStream field collision with base class - Fix blockHeight possibly undefined in confirmation - Remove unused imports and dead code - Cast test args as any to satisfy type constraints - Add operational logging to csp.ts (stream lifecycle, failover events, block-by-date resolution) - Rename _enforceFloorSemantics to _verifyBlockBeforeDate
- Rename IProviderConfig to IMultiProviderConfig with only health/priority/timeout fields - Move apiKey to global config.externalProviders.alchemy (matches Moralis pattern) - Resolve Alchemy URLs dynamically per-call via ALCHEMY_NETWORK_MAP - Add chain/network to AdapterBlockByDateParams for dynamic URL resolution - Add blockAtTimeCache (LRU per chain:network) to multi-provider CSP - Rename isBreakerable to affectsHealth across error taxonomy - Update all tests (47 passing)
