**class** ``TextPacingConfig``

    Word-rate emulation for paced streaming text input.

**Fields:**

``tokens_per_second`` : *float* = ``20.0``
    Emulated upstream text rate in whitespace-delimited words/sec. The field name is retained for configuration compatibility.

``tokens_per_delta`` : *int* = ``1``
    Whitespace-delimited words per input append event. The field name is retained for configuration compatibility.

``gap_distribution`` : *str* = ``"fixed"``
    Inter-delta gap distribution: fixed | poisson.

``initial_delay_s`` : *float* = ``0.0``
    Delay before the first delta (upstream TTFT emulation).

``seed`` : *int* = ``42``
    Base seed for per-request gap jitter (request seed = seed + request_id).
