-## Voice noise suppression configuration object
-
-The instance rollout of client-side noise suppression. [Experiments](/http-api/experiments/) defines what a client resolves from it and the closed [backend registry](/http-api/experiments/#noise-suppression-backends) every backend field draws on.
-
-### Structure
-
-| Field | Type | Description |
-| --- | --- | --- |
-| enabled | boolean | Whether the rollout runs at all (default false) |
-| config_version | integer | Revision counter, raised by Fluxer and never accepted from a request |
-| default_backend | string | Backend given to an account the rollout selects (default `standard`) |
-| enabled_backends | array[string] | Backends a client MAY run, up to 7 entries (default every backend) |
-| allow_user_override | boolean | Whether an account's own choice replaces the assigned backend (default true) |
-| rollout_basis_points | integer | Share of accounts the rollout selects, in basis points (0-10000, default 0) |
-| rollout_salt | string | Salt of the sampling hash (1-64 characters, default `voice-ns-v1`) |
-| included_user_ids | array[snowflake] | Accounts the rollout always selects, up to 1000 entries (default empty) |
-| included_guild_ids | array[snowflake] | Guilds whose members the rollout always selects, up to 1000 entries (default empty) |
-| include_premium_users | boolean | Whether the rollout always selects accounts with active premium (default false) |
-| excluded_user_ids | array[snowflake] | Accounts the rollout never selects, up to 1000 entries (default empty) |
-| guild_overrides | array[[guild override](/http-api/experiments/#noise-suppression-guild-override-object) object] | Per-guild replacements, up to 200 entries (default empty) |
-| suppression_strength | integer | Suppression strength (0-100, default 80) |
-
-Every field is present on read. An absent document or missing field uses the defaults above.
-
-`excluded_user_ids` wins over every other rule. Otherwise the rollout selects an account in `included_user_ids`, a member of a guild in `included_guild_ids`, or a premium account while `include_premium_users` is true, whatever `rollout_basis_points` says. A `default_backend` or `guild_overrides` entry naming a backend outside `enabled_backends` is dropped from what a client is served, and the stored value is kept as written.
-
-How often a client revalidates this rollout is not set here. It is set once for every experiment in the [experiment delivery configuration](#experiment-delivery-configuration-object) below.

 `push_relay` takes only `relay_consent_accepted`. Fluxer sets `relay_consent_accepted_at` and `relay_consent_accepted_by` itself on the request that changes that flag, and accepts neither from a request. Turning the flag on stamps the current time and the acting account, and turning it off clears both to null. A request that repeats the flag it already holds leaves the stamp alone.
