### `binder_append`

- 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
Append one settlement leaf (x402 | stripe_mpp | agentcore) under your task_id. Free.
```

### `binder_seal`

- 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
Seal ≥2 distinct rails under task_id into a portable Ed25519 binder (~$0.05 USDC on Base when paid).
```

### `binder_verify`

- 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
Verify binder integrity (sig + ordered leaf hashes). Does not prove underlying settlement.
```

### `health`

- 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
Liveness, rails, pubkey, paid/listing flags.
```
