 ### 1. Discovery
 
-The discovery loop rotates through enabled subreddits and authenticated runtimes. A runtime fetches Reddit `/new` data using the process-shared `RedditRequestCoordinator`. In the default `post-author` targeting mode those posts enter intake directly. An image subreddit configured for `comment-author` instead reads top-level comments from at most five newly listed posts and batches previously unseen eligible comment text through the reaction classifier. Candidates require a verdict at or above 0.8 confidence that the commenter wants to receive or experience the depicted person's role; comments describing what their author would do to the pictured person do not qualify. When `reddit.targetGenders` is non-empty, the expressed gender perspective must also be included. An `unknown` perspective fails closed unless explicitly targeted. A bounded in-process cache prevents unchanged comments from repeatedly consuming model calls. The candidate ID, author, timestamp, and permalink come from the comment while the original post image and title remain attached as preparation context; the usual image screen later verifies the depicted gender against the same target list. Intake then deduplicates candidate IDs and authors, excludes processed/contacted history, stores the full snapshot, source type, weight, and timestamps, and logs exact intake counts. Queued comments carry the classifier-policy version; active candidates admitted by the broader historical role policy are rejected on upgrade rather than allowed to send.
+The discovery loop rotates through enabled subreddits and authenticated runtimes. A runtime fetches Reddit `/new` data using the process-shared `RedditRequestCoordinator`. In the default `post-author` targeting mode those posts enter intake directly. An image subreddit configured for `comment-author` admits each newly listed source post to a durable SQLite watchlist until the post leaves `reddit.recentWindowMinutes`. Each poll rotates to the least-recently checked source post and requests a bounded batch of up to 100 comments sorted newest-first, so a source remains eligible to produce later commenter candidates after its first scan and across process restarts. Comment IDs and body hashes retain prompt-free classifier verdicts; unchanged comments do not consume another model call, while an edited body is reclassified. Candidates require a verdict at or above 0.8 confidence that the commenter wants to receive or experience the depicted person's role; comments describing what their author would do to the pictured person do not qualify. When `reddit.targetGenders` is non-empty, the expressed gender perspective must also be included. An `unknown` perspective fails closed unless explicitly targeted. The candidate ID, author, timestamp, and permalink come from the comment while the original post image and title remain attached as preparation context; the usual image screen later verifies the depicted gender against the same target list. Intake then deduplicates candidate IDs and authors, excludes processed/contacted history, stores the full snapshot, source type, weight, and timestamps, and logs exact intake and comment-gate counts. Queued comments carry the classifier-policy version; active candidates admitted by the broader historical role policy are rejected on upgrade rather than allowed to send.
 
 The queue grows to a demand-based target rather than a fixed backlog. The target is the smaller of configured `reddit.maxReadyCandidates` and the work that authenticated running accounts can still send within the recent-post window, accounting for rolling hourly capacity and minimum message spacing. Intake admits only the current deficit, newest Reddit posts first, pauses at zero outbound capacity, and reports fetched posts left unevaluated because the funnel is full. Reddit request pacing, not a tight application poll, remains the primary request limiter.
