## Changes things (7)

Creates or changes something that can be changed back. Claude Code: ask.

### `trial_fork_pair`

- The name "trial_fork_pair" says "fork": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Fork a checkpoint-paired assignment for one task (blinded arms A/B).
```

### `trial_register_protocol`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Register a hash-bound trial protocol; twins fork from the identical checkpoint, exactly one registered variable may differ.
```

### `trial_run_pair`

- The name "trial_run_pair" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Run one pair with the deterministic scripted agent and score blind. $0.25/pair, first 10 free once per operator.
```

### `trial_score`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Alias of trial_submit_outputs (blinded scoring).
```

### `trial_submit_outputs`

- The name "trial_submit_outputs" says "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submit the operator twins' outputs for one pair; blinded deterministic scoring. $0.25/pair, first 10 free once per operator.
```

### `trial_unblind`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Unblind after the verdict; hashed signed receipt covering every pair.
```

### `trial_verdict`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Trial verdict under the enforced stopping rule.
```
