From 1244eb6c4fb24bb5eb9b194bca8bf57bd27544ef Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 17 Jul 2026 08:02:05 -0500 Subject: [PATCH] =?UTF-8?q?feat(protocol2):=20presence=20stream=20?= =?UTF-8?q?=E2=80=94=20online=20population=20+=20region=20transitions=20(P?= =?UTF-8?q?art=20B=20ph.2)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Overlay BridgePresence (new): - presence.online sweep over online PlayerMobiles: total plus per-facet and per-region counts, emitted only when the population changes. - region.enter real-time from EventSink.OnEnterRegion (player-filtered), the cheap location signal PLAN.md prefers over Movement. - PresenceSweepSeconds (30s); wired into [bridge reload|sweepnow|status. Sidecar: - GET /online serves the latest presence.online snapshot from the event store (survives restart); population time series via /history?kind=presence.online. Docs: INTEGRATION.md presence events + /online endpoint; PROTOCOL_2 ph.2 built. Verified: sidecar cargo check clean; overlay compiles in the full ServUO Scripts tree (0 errors, 0 warnings). Live run pending.
