 - Growth deliberately continues while an account is held out of outbound messaging, because building the history is what lifts that hold. It is always the lowest-priority work an account performs, after inbound replies.
 - Dry run prepares and records a comment but never posts it. Every posted comment, and every comment refused by either gate, is kept with its reason in the growth audit trail.
 
-Browsing simulation is a separate, disabled-by-default account-growth experiment. It selects a conservative number of eligible posts or comments from the same configured communities and records a hypothetical upvote, but it cannot submit a vote: the service has no Reddit vote method or write transport. Owned-account content, outreach recipients, cross-account duplicates, growth-comment threads, promotion experiments, moderator content, closed or removed threads, old or low-context items, and NSFW content unless explicitly allowed are excluded before randomness is applied. Simulation records never affect the adaptive comment-growth trust level.
+Browsing sessions are a separate, disabled-by-default account-growth experiment. They select a conservative number of eligible posts or comments from the same configured communities. The per-account automatic-upvote switch is separately disabled by default; when enabled, a selected item is upvoted through the account's authenticated browser session only in running mode and outside browser dry-run. Owned-account content, outreach recipients, cross-account duplicates, growth-comment threads, promotion experiments, moderator content, closed or removed threads, old or low-context items, and NSFW content unless explicitly allowed are excluded before randomness is applied. Every selection records whether Reddit confirmed the vote, and browsing never affects the adaptive comment-growth trust level.
