Reach
A mention in the Necropolis wakes one bounded turn. Reach admits the event, forms an answer under a pinned Persona, and records whether the external place received it. The platform account remains a way to appear there, without becoming the Lich.
Habitat defines who and what may enter that social place. Turn follows a question through committed answer and delivery. Deployment profiles choose where its durable authority and transport custody live.
reach.discord revision 1 publishes reach.external_converse@1, reach.external_summon@1, and reach.external_presence@1. An allowlisted mention, guild command, or policy-admitted internal event may return ReachTurn@1 and optional ReachDelivery@1.
Reach stops before cross-place identity/continuity, moderation, ambient surveillance, attachments, DMs, shell, deployment effects, and platform-settled consent. Avatar may bind presentation, while Reach retains the event, audience, turn, delivery, and receipt. One result gives no next projection its authority.
