 Community weights feed a new weighted-random pick for each discovered growth thread. The grower queues only one new thread at a time, drains due retries and existing queue work before polling another community, and exposes an account-scoped queue clear that removes only unposted discovered/retryable rows.
 
+Browsing simulation is configured separately per account through `/api/growth/{accountId}/browsing` and reuses the enabled growth-community list and weights. It defaults off, targets 3–6 hypothetical selections per local day with a 60/40 post/comment split, enforces at least 45 minutes between sessions, respects quiet hours, excludes NSFW unless enabled, and has a non-overridable 12/day ceiling. `nextDueAt` is service-owned durable state and cannot be set through the API. Browser dry-run does not change the behavior because simulation never performs a remote write.

 ## Runtime-editable subset
 
 The dashboard/API exposes a deliberate subset: rate limits, dry-run, recency and ready-funnel limits, subreddit definitions/conversation behavior, and selected advanced configuration. Shared transport schemas live in `packages/api-contracts/src/config.ts`; the backend source schema is still the final validator.
