| Span Name | Parent | Source File | Description |

| `pathfind.request` | `rpc.command.*` | PathRequest.cpp | `path_find` / `ripple_path_find` RPC entry |
| `pathfind.request` | `rpc.process` | PathFind.cpp | `path_find` RPC entry (`doPathFind`) |
| `pathfind.compute` | `pathfind.request` | PathRequest.cpp | Path computation for one request (`PathRequest::doUpdate`) |
| `pathfind.discover` | `pathfind.compute` | Pathfinder.cpp | Graph exploration (one per RPC call) |
| `pathfind.update_all` | — | PathRequest.cpp | Async recomputation of all active requests at ledger close |
> **Note**: `pathfind.request` parents to `rpc.process`, not `rpc.command.*`.
> `rpc.command.*` is intentionally unscoped: its generic dispatch (`callMethod`)
> also wraps `doRipplePathFind`, whose span is held across a coroutine
> `yield()` — scoping it would risk a wrong-thread scope pop on resume. The
> `pathfind.request → compute → discover` sub-tree nests correctly because those
> handlers run synchronously (no yield) and use `ScopedSpanGuard`.
**Where to find**: Tempo → TraceQL: `{resource.service.name="xrpld" && name=~"pathfind.*"}`
