 The inbound event key, intended reply, claim status, and conversation state make retries idempotent. Immediately after any limiter wait, automation refreshes Matrix and revalidates the latest inbound event, boundaries, images, the shared seller/off-platform decision, policy status, and the one-media-request limit. Newer state makes the old claim terminally `superseded`; it is never sent. If the replacement event is a seller or off-platform push, the same revalidation ends and classifies the conversation instead of leaving it for a later pass. If the process dies after Matrix accepted a reply, reconciliation finds the outbound event and marks the old claim sent instead of sending it again.
 
+Engagement-only conversations use the same confirmed-opener, durable-state, and newest-inbound eligibility checks, but stop before reply claims, media exchange, second-stage screening, or generation. The first verified reply persists the `engaged` terminal state, supersedes any stale claim defensively, and resolves triage to Done. Seller/off-platform rules still run during the shared retrospective scan and may classify the conversation more specifically, but neither path sends a reply.
+
 General R4R generation explicitly permits consensual adult NSFW conversation. A model response that softly refuses, moralizes, or diverts solely because the topic is sexual is rejected before send and falls through to the next configured chat model. General replies may offer a generic approved saved picture without that offer being miscounted as a request for recipient media. Prompt instructions and deterministic output validation also keep generated private-chat text within deliverable capabilities: text and the approved saved-picture flow are supported, while voice notes, audio messages, and live voice/video/phone calls are rejected before a suggestion or automated reply can proceed.
 
 Legacy conversations may make at most one optional autonomous media request, including a request already present in the opener. The hybrid policy retains its single rapport-gated media ask. Deterministic, sequence-aware refusal checks run before generation and again at send time; generated media asks must pass the same non-explicit, non-coercive validator.

 The conversation inbox assigns every row to exactly one primary workflow queue: **Needs attention**, **Waiting**, **Sellers**, **Snoozed**, **Done**, **Deleted**, or **Archived**. Removed-account history belongs only to Archived, deleted recipients belong only to Deleted, and seller/off-platform outcomes belong only to Sellers, so none can leak into actionable work. Unread state, manual ownership, and received images are independent badges and secondary toggles rather than competing queues. The default queue is Needs attention. Suspended profiles are not treated as deleted.

+The snapshot matters: changing configuration later must not silently rewrite the rules for an active conversation. Engagement mode marks the conversation and operator triage done as soon as the first post-opener inbound event is durably observed; it does not generate, claim, or send a reply. Other automation stops for seller/upsell evidence, an image received, a detected boundary, unsafe content, an exhausted turn budget, a repeated media request, or a manual policy.
 
 Within those boundaries, R4R replies are expected to participate naturally in consensual adult NSFW conversation instead of moralizing, declining the topic, or diverting ordinary flirting into generic small talk. In-character soft refusals are treated like provider refusals and fall through to the next configured chat model. This does not weaken recipient boundaries, the under-18 handoff, seller/off-platform controls, location and meeting prohibitions, or the separate media-request rules.
