- Add AssetConversion model for routing audit trail - Add src/stellar/routing.ts with strict-send/receive path finding - Add RoutedQuote type with slippage protection - Add buildPathPaymentOp for operation construction - Add quote validation and slippage clamping utilities - Add migration for asset_conversions table This provides the foundation for atomic asset conversion at deposit/withdrawal time with explicit slippage bounds and quote TTL.
…eurowealth#340) - Add INBOUND_TRANSFER and CLAIMABLE_BALANCE_CLAIM transaction types - Add InboundOperation model for idempotency on (txHash, operationIndex) - Add InboundCursor model for per-account ledger tracking - Add src/stellar/claimableBalances.ts with poller and predicate evaluation - Add reconcileInboundOperations for unmatched payment detection - Add migration for inbound operations and cursor tables This provides the foundation for detecting and claiming claimable balances addressed to platform accounts and reconciling direct inbound payments.
- Add TREASURY_SWEEP to OutboxOpKind enum - Add TreasuryTier enum (HOT, WARM, COLD) - Add TreasuryAccount model with tiered balance bands - Add TreasurySweep model for sweep operation tracking - Add MultisigEnvelope model for signature collection - Add src/stellar/multisig.ts with envelope building and signature handling - Add src/jobs/treasurySweep.ts with balance evaluation and sweep planning - Add migration for treasury account tables This provides the foundation for hot/warm/cold account tiering with automated sweeps and multi-signature support for colder tiers.
…ealth#350) - Add ProtocolLiquiditySnapshot model for pool depth and TVL tracking - Add depth curve sampling for AMM-routed exits - Add src/analytics/liquidity.ts with pure core functions: - maxExitWithinSlippage for exitable amount calculation - timeToFullExit for exit duration estimation - liquidityScore for 0-100 liquidity scoring - Add configuration constants for slippage targets and snapshot TTL - Add migration for protocol liquidity snapshots table This provides the foundation for liquidity risk metrics per position and portfolio, including how much can be withdrawn within target slippage and estimated time to fully exit positions.

Path-Payment DEX Auto-Routing, Claimable-Balance Ingestion, Split-Custody Treasury, and Liquidity Risk Estimation
Summary
This PR implements minimal infrastructure for four major features:

Breaking Changes
None - these are additive changes that extend the existing schema and functionality.
Notes
This is a minimal implementation focused on infrastructure and data models. Full integration with existing systems (outbox dispatcher, event listener, API endpoints, etc.) would be addressed in follow-up issues. The implementations provide the foundational types, database schema, and core utilities needed for each feature.
