+# Route Decision Tree
+
+This document describes the live route-selection tree used by the Token Aggregation Service.
+
+## What It Does
+
+- Resolves pools from the live indexed database.
+- Normalizes token labels using the token table and canonical token list.
+- Falls back to raw addresses when token metadata is missing, so "missing quote token" pools still render.
+- Returns pool depth and freshness on every request.
+- Expands the route tree with bridge and destination-swap legs when a destination chain is provided.
+
+## API
+
+### Live tree
+
+```bash
+GET /api/v1/routes/tree?chainId=138&tokenIn=0x...&tokenOut=0x...&amountIn=1000000&destinationChainId=1
+```
+
+### Depth summary
+
+```bash
+GET /api/v1/routes/depth?chainId=138&tokenIn=0x...&tokenOut=0x...&amountIn=1000000&destinationChainId=1
+```
+
+## Decision Order
+
+1. Resolve the source token and destination token.
+2. Load all live pools for the source token on the source chain.
+3. Prefer direct pools for the requested pair, ordered by TVL.
+4. If a destination chain is provided, add:
+   - bridge leg
+   - destination swap leg, when destination liquidity exists
+5. Mark pools with stale or missing depth so routing can avoid them.
+
+## Decision Tree
+
+```mermaid
+flowchart TD
+  A["Start"] --> B["Resolve source token"]
+  B --> C["Load live source pools"]
+  C --> D{"Direct pool exists?"}
+  D -->|Yes| E["Rank by TVL and freshness"]
+  D -->|No| F["Bridge or fallback route"]
+  E --> G{"Destination chain provided?"}
+  F --> G
+  G -->|No| H["Return direct-pool decision"]
+  G -->|Yes| I["Add bridge leg"]
+  I --> J{"Destination liquidity exists?"}
+  J -->|Yes| K["Add destination swap leg"]
+  J -->|No| L["Bridge-only decision"]
+  K --> M["Return atomic-swap-bridge tree"]
+  L --> N["Return bridge-only tree"]
+```
+
+## Missing Quote Token Pools
+
+The service now resolves token labels in this order:
+
+1. Token row from the database.
+2. Canonical token mapping for the chain.
+3. Raw address fallback.
+
+That means pools with incomplete token metadata still appear in the API and UI, instead of collapsing to `?` or being dropped entirely.
+
+## Notes
+
+- Route depth is derived from current pool TVL and freshness.
+- The endpoint is intentionally short-cache so it follows the current pool index.
+- For the full funding flow, the tree reflects:
+  - direct pool on Chain 138
+  - atomic swap + bridge from Chain 138
+  - destination-side completion on the target chain
