# Read placement chronology

> Read one monitored placement’s retained source, target and index history with frozen continuation and explicit evidence gaps.

`get_placement_chronology`

Read one monitored placement’s retained source, target and index history with frozen continuation and explicit evidence gaps. This read performs no new checks.

<Note>Development preview. This command is absent from the verified deployed bundle. Use a matching development environment.</Note>

| Access | Behavior |
| - | - |
| `watches:read` | Reads saved data |

This read does not start a verification job.

## Example request

Connect through [MCP](/guides/connect-mcp), [CLI](/guides/connect-cli), or [HTTP](/guides/connect-http). Replace example identifiers with records from your workspace.

<CodeGroup>
  ```json MCP theme={null}
  {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "get_placement_chronology",
      "arguments": {
        "watchId": "watch_example",
        "limit": 50
      }
    }
  }
  ```

  ```bash CLI theme={null}
  agentlinkops call get_placement_chronology --args '{"watchId":"watch_example","limit":50}'
  ```

  ```bash HTTP theme={null}
  curl "$AGENTLINKOPS_API_URL/v1/commands/get_placement_chronology" \
    -H "Authorization: Bearer $AGENTLINKOPS_API_KEY" \
    -H 'Content-Type: application/json' \
    --data '{"watchId":"watch_example","limit":50}'
  ```
</CodeGroup>

## Returned result

Illustrative data validated against the documented response schema. IDs and dates are examples, not a live account capture. MCP returns this data in `structuredContent` and in a text content block; generic HTTP and CLI return the JSON result directly.

## Input fields

Omit optional fields when you do not want to supply them. Null is accepted only where listed. Unknown input properties are rejected.

| Field | Type | Presence | Meaning and constraints |
| - | - | - | - |
| `watchId` | string | Required | Identifier of the watch returned by its create or list operation. minLength: 1; maxLength: 200 |
| `limit` | integer | Optional | Maximum rows in this page or bounded report; subject to the schema maximum. minimum: 1; maximum: 100; default: 50 |
| `cursor` | string | Optional | Opaque continuation returned by this same listing; omit for the first page. maxLength: 12000 |
| `streams` | array | Optional | The streams value; allowed values and bounds are specified in this schema. minItems: 1; maxItems: 8 |

### Validation and omitted values

Reads one exact configured placement and independently scoped retained source, target, event, lifecycle and index streams. No provider call or new check occurs.

Continuation freezes insertion watermarks and rejects changed identity, grants or history floors. Observed time, recorded time and current raw-evidence availability remain separate. Expired evidence cannot become retained through a frozen cursor.

Loaded-page export preserves exact selected data, scope, snapshot identity, gaps and content hash. Caller-declared local submissions are unauthenticated context without server observation/receipt time or causal proof.

### Defaults when omitted

| Field | Default |
| - | - |
| `limit` | `50` |

## Output fields

Fields inside optional or nullable parents apply only when that parent exists. [Common schema conventions](/reference/schemas) explain evidence states, empty lists and extensions.

## Errors and retries

The command is annotated idempotent. Reuse an accepted idempotency key when the input provides one; changing the payload under a reused key can conflict.

See [error recovery](/reference/errors) for status, scope, cooldown, cursor and retry handling. Unknown observations are result data and do not establish loss.

## HTTP resource routes

These existing resource routes share the operation’s domain behavior. Their parameter placement, status and response envelope can differ from generic invocation. See [HTTP route details](/reference/http/routes).

| Method and route | Success | Details |
| - | - | - |
| `GET /v1/watches/{watchId}/chronology` | 200 | Reads frozen retained chronology; comma-separated streams, limit and cursor are query arguments. Denied streams disclose no counts. This read schedules no check. |
