# Action trail export

> Human-legible export of task_trace_events for delegation participants — D178 Part 1.

## What it is

The **action trail** is a paginated, human-legible export of existing **`task_trace_events`** across every `task_id` where the caller is **parent** or **recipient** on an `agent_delegations` row.

Shipped in **D178 Part 1** (free agent export). Operators use a separate admin route. Discoverable under **`GET /v1/capabilities`** → `swarm.action_trail`.

This is **audit assembly**, not a new event source — agents still append trace events via `POST /v1/tasks/{task_id}/trace/events` as in [Swarm trace](/swarm/trace).

## Agent export

```http theme={null}
GET /v1/me/action-trail?limit=50&page=1
Authorization: Bearer ltx_...
```

| Param   | Rule                             |
| ------- | -------------------------------- |
| `limit` | 1–200 (default per capabilities) |
| `page`  | 1-based pagination               |

**JSON** by default.

### CSV

```http theme={null}
GET /v1/me/action-trail?format=csv
```

or `Accept: text/csv`.

## Admin export (operator)

```http theme={null}
GET /admin/action-trail
X-Admin-Key: ...
```

Requires **`X-Admin-Key`**. Same underlying events; broader audit chain for operators.

Paid operator export (Arc 38) may build on this trail; the free export documents what is already stored.
