  REPLACES a bulk-sweep scaffold dated 2026-05-04 (roadmap#35) that declared
  X-RateLimit-Limit / X-RateLimit-Remaining / X-RateLimit-Reset response headers, 429
  and 503 status codes, and free/professional/enterprise per-minute quotas. GoReplay
  serves no HTTP endpoint, returns no headers and enforces no quota, so every one of
  those values was fictional. Discarded in full.

description: >-
  GoReplay publishes no API rate limits because it publishes no API. The `gor` binary
  runs on the customer's own hosts and never calls a GoReplay-operated endpoint, so
  there is no vendor-side quota, no throttling response and no rate-limit header to
  read. Recorded as an honest zero. What GoReplay does ship is the mirror image —
  OUTBOUND throttling controls the operator uses to protect their own replay target —
  captured below under `outbound_controls` so the distinction is not lost.

note: >-
  limit_count is 0 because the provider documents no inbound limits, not because the
  docs were unreachable. goreplay.org/docs/ returned 200 across all twenty pages
  probed on 2026-09-13 and none describes a vendor quota.

      The documentation set describes inputs, outputs, filtering, rewriting,
      middleware and operations. No endpoint, no authentication against a GoReplay
      service, no limits.

      The provider's own machine-readable summary lists only CLI commands and doc
      pages; it names no API host.
outbound_controls:
  description: >-
    GoReplay throttles what it EMITS toward a replay target the operator owns. These
    are product features, not vendor-imposed limits, and must not be read as
    rate limits in the scoring sense.
  controls:
    - name: replay speed modifier
      syntax: --input-file "requests.gor|200%"
      description: >-
        Scale replay rate as a percentage of the originally captured rate. 200%
        replays at twice production speed; values below 100% slow it down.
