+## Task 3.11: TX and TxQ Span Attribute Gap Fill
+
+**Status**: COMPLETE
+
+**Objective**: Add workflow-identifying attributes to transaction spans so operators can filter by transaction type and see outcomes without off-chain correlation.
+
+**Attributes added**:
+
+| Span            | Attribute        | Type   | Source                                                              |
+| --------------- | ---------------- | ------ | ------------------------------------------------------------------- |
+| `tx.process`    | `tx_type`        | string | `TxFormats::getInstance().findByType(stx->getTxnType())->getName()` |
+| `tx.process`    | `fee`            | int64  | `stx->getFieldAmount(sfFee).xrp().drops()`                          |
+| `tx.process`    | `sequence`       | int64  | `stx->getSeqProxy().value()`                                        |
+| `tx.process`    | `ter_result`     | string | `transToken(e.result)` (set after batch application)                |
+| `tx.process`    | `applied`        | bool   | `e.applied` (set after batch application)                           |
+| `tx.receive`    | `tx_type`        | string | `TxFormats::getInstance().findByType(stx->getTxnType())->getName()` |
+| `txq.enqueue`   | `tx_type`        | string | same pattern as above                                               |
+| `txq.accept.tx` | `txq_status`     | string | `applied` / `failed` / `retried`                                    |
+| `txq.accept`    | `ledger_changed` | bool   | set at end of accept loop                                           |
+
+**New attr keys**: `TxSpanNames.h` (`txType`, `fee`, `sequence`, `terResult`, `applied`), `TxQSpanNames.h` (`txType`).
+
+**Modified files**:

+- `src/xrpld/app/misc/TxSpanNames.h`
+- `src/xrpld/app/misc/detail/TxQSpanNames.h`
+- `src/xrpld/app/misc/NetworkOPs.cpp`
