+**Rust's own world events need no plugin** (`docs/modules/rust/PLAN_REDESIGNS.md` §14.3.1). The patrol
+helicopter, Bradley, the cargo ship, the Chinook, airdrops, locked crates, the Travelling Vendor, the
+satellite and the Deep Sea reach the feed (a **World events** filter) and each is an engagement trigger
+(`rust.world.<event>`), so a notice or an event's phase can follow one. The event and its grid are public;
+a player's name in it only for the presence audience, a Steam id only for staff. **Who downs a helicopter
+or a Bradley** is the operator's rule per server — killing blow (the default), last hit, most damage, or
+everyone who hurt it — and the same rule writes the line and counts toward **Rotorbane** and
+**Tankbreaker**. **Safecracker** (locked crates hacked) and **Scavenger** (airdrops looted first) are
+title categories with leaderboard columns, and the **Call a world event** step (`rust.world.call`) calls
+one now, kept when the run ends: an airdrop or a patrol helicopter can be sent to a point.
+
 **Four uMod plugins are optional, and the module works without any of them** (`docs/modules/rust/PLAN.md`
 §33). The bridge plugin's hard requirements are **Kits** and **ZoneManager**.

+// ── Rust's own world events (protocol 14, PLAN_REDESIGNS §14.3.1) ──────────
+//
+// The patrol helicopter, Bradley, the cargo ship, the Chinook, airdrops, locked
+// crates, the Travelling Vendor, the satellite and the Deep Sea reach this
+// module as ONE frame kind, `world.event`, whose `event` says which (D349,
+// D353). This file is the one place that knows the 24 of them, and the three
+// readers — the feed, the ingest and the engagement triggers — all ask it.
+//
+// ── Why `event` and not `type` ─────────────────────────────────────────────
+//
+// The plan's example put the world event's type in `type`, which is the
+// envelope's field: the sidecar files a frame on it (`event`, `snapshot`,
+// `reply`), and it dropped every world event as untyped on the rig. Protocol
+// 13's `world.expired` hit the same collision and settled on its own field; so
+// does this one (stage 1, 2026-10-15).
+//
+// ── Who gets the credit (D372, D379) ───────────────────────────────────────
+//
+// For a patrol helicopter, a Chinook and a Bradley the plugin sends every
+// candidate — the killing blow, the last hit, the most damage, everyone who
+// hurt it — and decides nothing. The server's rule, chosen by its operator,
+// picks from them HERE, for the feed line and for Rotorbane / Tankbreaker
+// alike, so the two can never disagree. A rule changed applies from then on:
+// the counts already written stay as they were.
+//
+// ── Who may read what (D353, D376) ─────────────────────────────────────────
+//
+// The event and its grid are public. A player's name shows only to the
+// operator's presence audience — with presence left at staff, a signed-out
+// visitor reads "Patrol helicopter downed at G8" — and a Steam id only to staff.
+// A position never leaves this module: the map has its own audience for where
+// things are (D111), and the feed must not be a way round it. An event type
+// this build does not know is staff's alone (default deny, as `catalogue.js`).
+
+/**
+ * Every type the protocol defines (PROTOCOL.md §20.5), and what each carries.
