feat(rust): NPC sides, the faction table, an event's escort, ally and tether (runicnpc stage 5)

RunicNPC stage 5 on the site (docs runicnpc/PLAN.md, D253-D272):

- profiles gain the guard role, faction, relations (its own exceptions),
  alertRadius, turrets, hurtByPlayers, hurtsPlayers and kitUse, checked in
  RunicNPC's order and words, and defaulting to "players only" (D255);
- the faction table: one site-wide table, one row per pair and both ways
  (D254, D268), stored in rust_npc_factions, edited on the NPC profiles page
  (PUT /admin/rust/npcs/factions), pushed to every server with its
  profiles and hashed with them, and a standalone server's own pairs
  adopted at its first push with the site's winning (D244, D251);
- the Place NPCs step takes escort (a Steam id or a {placeholder}), an ally
  (a clan from the new rust.options.clans source, or the team of a player)
  and tether (the zone this event made), for a RunicNPC profile only
  (D269, D270, D272);
- a placement may be held inside a zone (tether, D272);
- the bridge's RunicNPC API floor is 4.

Tests: 488 server, 66 client. routes.manifest.json regenerated against the
pinned core (one route added).

-Two tables, `rust_servers` (configuration) and `rust_server_state` (what each sidecar reported).
+**Nothing names who is online by default.** The Online list, every feed item that says a named
+player was on the server (connects, respawns, deaths, chat, gather tallies) and the leaderboard's
+"last seen" reach **staff** unless an operator widens them in Admin → Rust visibility — fleet-wide,
+with an optional override per server. How many players are online is public at every setting. The
+viewer's standing is re-read from the database on each request, so a demotion or a ban applies at
+once rather than when a token expires.
 
-The rest of the module — identity, site-owned permissions, Teams from Rust's clans, notifications,
-events, the live map, Discord commands — arrives phase by phase. **Nothing is registered before it
+Every page reads this module's own tables and never calls a game server, which is what lets the
+whole surface render while every server in the fleet is off. Tab, feed filter, wipe and leaderboard
+sort all live in the URL, so any view of it is a link.
+
+Seven tables: `rust_servers` (configuration), `rust_server_state` and `rust_presence` (observed
+state), `rust_wipes`, `rust_players`, `rust_player_wipe_stats` and `rust_gather_totals` (the record a
+wipe does not erase), plus the bounded `rust_events` window and the `rust_ingest_cursor`.
+
+**Teams come from Rust's own clans**, not from the uMod Clans plugin, which is optional and whose
+clans never become Teams. A clan's roster reaches its own members and staff unless an operator
+widens it in Admin → Rust visibility; its name, colour, score and count are public. The game lists
+at most 100 clans per server, and a server at that ceiling answers core partially, so core never
+removes a Team on its word. Core holds one Team provider per site, which is one reason **a site runs
+one module**: core's installer refuses a second.
+
+**The next wipe is the operator's to state** (Admin → Rust servers): a rule — the monthly forced
+wipe only, weekly or every other week, each in the server's own time zone and always including the
+forced wipe (first Thursday, 19:00 UK time) — plus an optional one-off date that replaces the next
+computed wipe. It is computed on every read and never stored, so it cannot go stale after a wipe.
+The server list, the server page, the Android app and `/wipe` all show it.
+
+**Two uMod plugins are optional, and the module works without either** (`docs/modules/rust/PLAN.md`
+§33). The bridge plugin's hard requirements are **Kits** and **ZoneManager**.
+
+- **BetterChat** (LaserHydra, 5.2.15). With it: **chat titles** an operator sets per server — "top 3
+  playtime", "#1 kills" on the current wipe — shown in game chat and beside the name on the web and
+  app leaderboards; and a **chat style** on any permission group this site authors, all twelve of
+  BetterChat's group fields, mirrored like the group's permissions (a field changed in game is
+  reported, never overwritten). Without it the titles still show on the web and the app, and the
+  styles wait until it is installed.
+- **PopupNotifications** (k1lly0u, 0.2.1). With it: `rust.announce` and a server's news posts can be
+  a popup instead of a chat line. Without it a popup is refused with a sentence saying so, and chat
+  works as before.
+
+News and event lines said in chat can wear one styled group's title and colours — the
+**announcement voice**, chosen in Admin → Rust servers. The line is said by the bridge plugin with no
+player as its sender, so it looks the same with or without BetterChat.
+
+**The Discord commands answer from the tables, never from a game server**, inside core's three-second
+budget. Every refusal is private. **An answer narrower than public goes to the caller alone:** a
+moderator's `/online` in a public channel shows the names to the moderator, never to the channel, and
+the same for a clan roster. Everything else is posted where it was asked.
+
+The rest of the module arrives phase by phase. **Nothing is registered before it
 has something behind it:** a declared trigger nothing emits and a declared slot nothing fills are
 both surfaces an operator can configure and then wait on, which is worse than an absent one.
 
+### What a client feature-detects on
+
+`module.json` declares six capability strings, and `GET /api/v1/public/modules` hands them to any
+client that asks — the website's own nav, and the Android app (`docs/modules/rust/PLAN.md` R10).
+Five of them name a surface: `servers`, `killfeed`, `leaderboard`, `presence`, `wipes`.
+
+The sixth is `rust`, and it names **the module itself**. It looks redundant beside `id`, and it is
+not, for two reasons worth writing down before somebody tidies it away:
+
+- **A client that asks "is this module installed" has nowhere else to ask.** Core flattens every
+  started module's capabilities into one list, so `servers` alone is a word another module could
+  declare tomorrow and silently reveal this one's screens. `rust` is the string that can only mean
+  this module, and it is the single gate a whole navigation group hangs on — exactly the job `shard`
+  does for `module-uo`.
+- **`id` answers a different question.** It is a *mount prefix* (§2.1 requires it to equal the
+  directory core loads the module from), and `MODULE_API.md` §2.9 is explicit that a client must
+  never infer a route from a capability. Gating on `id` would quietly make the two the same thing,
+  and the day a client builds `/<id>/servers` from it, the contract that lets this module move its
+  own pages is gone.
+
+An unknown capability is absent, and no route is ever derived from one.

+// ── This module's fill for core's `site.footer.status` slot ───────────────
+//
+// R13, and the contract is MODULE_API.md §3.7. Core owns the position in the
+// footer's info row and the separator around it, and passes `linkStyle` so the
+// row stays visually one row. **The label, the destination, the data and whether
+// anything renders at all are this component's** — that is the whole division,
+// and it is why the slot is named for a place rather than for a meaning.
+//
+// ── The live count, and what it costs ─────────────────────────────────────
+//
+// The org lead chose a live count ("3 servers · 42 online") over a static link,
+// so this fetches. Be clear-eyed about where it fetches from: core renders
+// `SiteFooter` inside `PublicLayout`, and every public page renders
+// `PublicLayout` ITSELF (§3.3) — so this component mounts once per public page
+// view, not once per session. Every public page on the site therefore carries one
+// `/public/rust/servers` request, including pages that have nothing to do with
+// Rust.
+//
+// Two things keep that honest rather than merely cheap:
+//
+//  • **It renders NOTHING until it has an answer, and nothing again if the
+//    request fails.** An unfilled slot renders nothing and core's `wrap` takes
+//    the separator with it, so a failed fetch degrades to exactly the footer an
+//    instance with no module installed has. A spinner in a footer would be worse
+//    than silence on every page of the site.
+//  • **It never polls.** One request per page view is a cost; a timer in the
+//    footer of every page would be a different kind of thing entirely.
+//
+// If that per-page request ever shows up in an operator's logs as a problem, the
+// fix is a short-lived module-scope cache here — the decision to keep the number
+// live stays intact, and nothing else on the site has to change.

+// four layers, each with its own switch, polled every ten seconds while the tab
+// is visible (D14) and not at all while it is hidden.
+//
+// **Nothing here decides who may see what.** The server sends only the layers
+// this viewer may see — a hidden one is absent from the answer, not present and
+// hidden — so the checkboxes below are a reader's convenience and never a
+// boundary. A layer the viewer cannot see is still LISTED, disabled, with who
+// can: "staff only" explains an empty map where silence would imply an empty
+// server (§23.3's shape).
+//
+// Leaflet arrives in a chunk of its own when this tab first mounts (D120, see
+// `lib/leaflet.js`). The page draws with circle and div markers only, so
+// Leaflet's image assets are never needed.

+//     started module's chunk into its shell. Leaflet in it would be ~40 KB gz on
+//     the home page, the forum and the news, for a tab most visitors never open.
+//   • Leaflet touches `document` and `window` the moment it is evaluated. The
+//     chunk is evaluated in Node by `test/registration.test.js`, with a
+//     `window` and nothing else — so Leaflet in the entry chunk fails that test
+//     at import, before a single registration is checked.
+//
+// Vite emits this as `dist/map-<hash>.js` beside `entry.js`. Core serves the
+// directory `client.entry` sits in (MODULE_API.md §3.1), and `release.yml`
+// copies every `.js` in it — `test/build.test.js` holds both ends of that.
+//
+// The ESM build is imported by path: Leaflet 1.9.4's package.json names only its
+// UMD file, and the UMD one would go through CommonJS interop for nothing.
+//
+// The stylesheet comes in as a STRING and is injected once as a `<style>` by the

+// somebody's filesystem.
+//
+// **What is on the screen is decided by what is dangerous about the action.**
+// Four things are true here that are not true anywhere else in this module, and
+// each of them is a piece of the page rather than a line in a doc:
+//
+//   • a save can take a required plugin DOWN. So the reload target is a
+//     deliberate choice with the folder name as a guess, the result is reported
+//     as its own panel, and a rollback shows the server's own log line.
+//   • the form cannot express everything a config holds. A `null`, an empty
+//     array and anything past the depth limit are marked and sent to the raw
+//     tier rather than half-drawn.
+//   • three keys in the bridge's own config would cut the link carrying the
+//     edit, or split the server's history. They render read-only, with the
+//     reason (D38).
+//   • configs hold API keys and Discord webhooks. Those fields render masked
+//     with a reveal, which is about the shoulder rather than the wire: an admin
+//     can already read the file over SSH (D37), and the audit trail never
+//     records the values either way.

+//
+// Where RunicNPC's profiles are authored (D216: no in-game editor). A profile is
+// for one server, several, or every server, like a zone preset, and the site
+// pushes each server its set, which RunicNPC then holds as managed (D221).
+//
+// The first push to a server adopts that server's own profiles as profiles for
+// it alone (D244); one whose name a site profile already had there is kept
+// aside as "replaced" (D251), listed below with a Restore. Each profile says how
+// its kills are counted on the leaderboard and in titles (D247).
+//
+// Stage 5: a profile's side (its faction, its own exceptions, its alert radius),
+// turrets, the two PVE checkboxes and the kit's extras; and the site's one
+// faction table, pushed to every server with the profiles (D254, D268).

+// The permission manager (PLAN_REDESIGNS §1). The site owns every permission and
+// group on every server (D160), and this screen follows uMod PermissionsManager's
+// flow (D162): a server, then players ⇄ groups, then a subject, then one plugin's
+// permissions with Granted / Revoked, Grant all and Revoke all.
+//
+// Three rules shape it:
+//
+//   • **Every toggle says what is true on THIS server** (U-1): granted,
+//     waiting for a sync, through a group, waiting for a first connection, not
+//     registered here, or did not land. A state in a server-level sentence is a
+//     state nobody reads.
+//   • **Plugins are who REGISTERED a permission, never its prefix.**
+//     `zonemanager.ignoreflag.nokits` is ZoneManager's.
+//   • **Anything that reaches further than this server says so and asks.** A
+//     fleet-wide grant is revoked everywhere or only here; a shared group is
+//     changed everywhere or split for this server (D190's two answers, offered
+//     to a person).
+//
+// Every subject is named by linked account and in-game name, or by Steam id
+// when there is neither (D163). The screen never writes to a game: every button
+// writes to the site, and the sync loop settles it within seconds — except
+// *Sync now*.

+//
+// The page the module did not have. Until phase 16 a server row was written only
+// through `PUT /admin/rust/servers/:id` — D106 recorded it, and the README said
+// "in Admin → Rust, add a server" about a page that did not exist. D130's wipe
+// schedule needed somewhere to be typed, and the org lead chose to build the
+// missing page rather than hang the schedule on the visibility page (D133).
+//
+// One form for adding and editing, because they are one `PUT`. Three rules it
+// keeps from the API:
+//
+//  1. **The token is write-only.** The field is blank on every edit, a blank
+//     save leaves the stored one alone, and the row says whether one is stored.
+//  2. **The protocol a row was configured against is kept.** The `PUT` defaults
+//     an omitted protocol to this build's, so an edit sends the stored value back
+//     rather than silently re-stamping the row.
+//  3. **The wipe schedule is the operator's words, not the forecast.** The form
+//     shows what was stored; the row shows what it computes to, from the same
+//     answer the public pages read.
+//
+// Test and Delete act at once rather than on Save — they are questions put to a
+// sidecar and a removal, not settings.
+//
+// Phase 17 added a server's chat titles and the announcement voice, in
+// `ChatTitles.jsx`, each saved on its own.

+//
+// Who may see who is online. The org lead's rule (2026-09-22): nothing names who
+// is online by default — the narrowest audience, staff, unless an operator
+// deliberately widens it here. A count of players is public at every setting.
+//
+// One fleet default and an optional override per server, because a creative or
+// PvE server may reasonably publish a roll call a PvP server must not — and a
+// server that has not chosen follows the fleet, so narrowing the fleet narrows
+// every server that never said otherwise.
+//
+// The page says what "who is online" covers, because it is wider than the tab
+// of the same name: the killfeed, chat and joins in the feed, and the
+// leaderboard's "last seen" all name a player who was on at a given moment.
+//
+// Phase 9 adds a second setting beside it: who may see a CLAN ROSTER (D48). It
+// defaults to the clan's own members and staff, and widening it widens online
+// status too, because a roster row carries it — the page says so. The same card
+// lists each server's clan board: a server whose clans cannot be read, one at
+// the game's 100-clan ceiling (D55), and one running the uMod Clans plugin,
+// whose clans are a separate system and never Teams (D47).
+//
+// Phase 13b adds a third (D104, D106): whether a published news post is also
+// said in each server's in-game chat. Off by default, because core sends every
+// post to every registered leg — without a switch, the day this module updated,
+// every post would start appearing in every server's chat. It lives here because
+// this is the one page that lists every server with a setting of its own.
+//
+// Phase 14 adds the live map's switches (D114): four layers, each with a fleet
+// audience and an optional per-server override, and the own-and-mates switch
+// (D118). Beside each server is what its map picture is, and the two buttons
+// that act at once rather than on Save: Fetch again, and Render now — shown only
+// where there is no picture, with how long it will stall that server (D109).
+//
+// PLAN_REDESIGNS §4 adds which monuments the map draws (D196): a switch per
+// monument label, because that is what staff read and it groups the variants
+// (31 substations of four prefabs are one "Substation"). The minor labels start
+// hidden and every other label drawn, so a monument Facepunch adds appears. One
+// fleet list, and each server's own labels with an override each.

+// that into the module's own namespace root — so this page's address is the one
+// an operator links to when they mean "our Rust servers".

+// you write one; the only differences are where React comes from (core, via the
 // aliases in `vite.config.js`, so the import below looks completely normal and is
 // not) and where the chrome comes from (`../../core.js`, the shared UI kit).
 //
-// **Render `PublicLayout` yourself.** Core wraps public routes in its maintenance
-// gate and nothing else, so a page that omits the layout renders bare — no
-// header, no footer, no site chrome — which looks like a bug and is the contract
-// (§3.3). Admin and player routes are the other way round: core wraps those.
+// **Render `PublicLayout` yourself, and pass a `shell`.** Core wraps public
+// routes in its maintenance gate and nothing else, so a page that omits the
+// layout renders bare; without a `shell` it renders full-bleed with the footer
+// riding up underneath it. Name a width, never a class — the classes are core's
+// (MODULE_API.md §3.3).

-// **And pass a `shell`.** The layout is the chrome; `shell` is the body — the
-// centred column, the vertical padding, and the thing that holds the footer at
-// the bottom of the viewport. Widths are 'narrow', 'mid' and 'wide'; name a
-// width, never a class, because the classes belong to core's stylesheet.
-//
-// This is the phase-1 version of the landing page R8 calls for. It lists servers

+// **The boundary is enforced HERE, on the side that serves, and not on the wire.**
+// The plugin could have stamped a `class` on every frame and saved this file the

+// widen. Core's own shard fan-out works the same way: a public stream with an
+// allowlist of kinds, and an admin stream that adds the rest.
+//

+// an allowlist the new kind is invisible until somebody adds it here, which is
+// the same moment they think about it.

+// whatever plugins an operator happens to have installed, including ones added
+// after we shipped. This file is the half of that which cannot be done naively.
+//
+// ── The trap ──────────────────────────────────────────────────────────────
+//
+// **JavaScript cannot tell `1` from `1.0`.** `JSON.parse('{"Rate":1.0}')` yields
+// the number `1`, and `JSON.stringify` writes it back as `1`. Both frameworks
+// deserialize a config into typed C# classes, so a naive read-modify-write
+// silently rewrites every whole-numbered float as an integer — **on fields
+// nobody touched** — and Newtonsoft may coerce it or may throw. A throw at load
+// means the plugin does not come back, and R6/R17 make four of them required.
+//
+// The fields at risk are exactly the ones a Rust server tunes: gather rates,
+// multipliers, scales.
+//
+// ── So nothing here ever parses, mutates and re-serialises ────────────────
+//
+// `scan` is a JSON reader that records, for every value, the **span of source
+// text** it came from. `applyEdits` splices new literals into those spans and

+// author's indentation, key order, and the `.0` on a float nobody edited.

+//     as a JavaScript number. `2.50` stays `2.50`; `1.0` stays `1.0`. The value
+//     never becomes a `Number` anywhere in this module, which is the only way to
+//     be sure it cannot be re-serialised into something else.
+//  2. **The generated form is type-preserving.** An edit may change what a value
+//     IS, never what KIND of thing it is; changing a number into a string, or
+//     adding a key, is a structural change and belongs in the raw-JSON tier,

+// ── What happened, told to core's engagement engine ───────────────────────
+//
+// The fan-out behind `triggers.js` (PLAN.md §25). Ingest calls `onEvent` for
+// every frame it stores; the refresh calls `serverObserved` for every poll;
+// ingest calls `checkLeader` after a batch; the prune timer calls
+// `sweepLoginDenied`; the link route calls `linked`.
+//
+// **Nothing here decides who is told.** It says what happened and, for a
+// personal or clan event, who it is ABOUT. Core applies the rule, the ceiling,
+// the preference, the suppression list and the verification gate. A module
+// cannot send mail (MODULE_API.md §2.7), and this file is not the back door.
+//
+// **Nothing here throws into its caller.** Every entry point catches, because
+// its callers are the ingest cursor and the refresh loop — a malformed frame or
+// a core-side contract problem must cost one notification and never the feed.
+//
+// ── Three rules the whole file follows ────────────────────────────────────
+//
+//   1. **Emit on the transition, never on the poll** (R7). A server that is
+//      still up is not news. Transitions are tracked in memory, and a FIRST
+//      sighting is never one — so a website restart announces nothing.
+//
+//   2. **A replayed event notifies only while it is still news** (D63). After an
+//      outage the cursor replays hours of frames. A broadcast older than 15
+//      minutes tells nobody; a personal or staff event is kept for 24 hours,
+//      because "your base was raided at 03:10" is still true and still wanted.
+//
+//   3. **Every emit carries a dedupe key made from the EVENT, not the store.**
+//      Core's outbox is unique on (rule, user, channel, key), so the same frame
+//      replayed after a crash is a no-op. The key is built from what the event
+//      says — its server, time and subject — rather than from the sidecar's row
+//      id, because a sidecar whose database is replaced starts its ids again
+//      and would otherwise have every new alert swallowed as a repeat of an old
+//      one.

+// ── What the notifications read like, and the rules that use them ─────────
+//
+// `registerEngagementSeeds` (MODULE_API.md §2.4 and §1.1 under 1.9.0; PLAN.md
+// §25.2). Data only: nothing here names a recipient, and nothing here turns a
+// rule on.
+//
+// ── Two bespoke bodies, and why only two ──────────────────────────────────
+//
+// A body earns its place when the message has something to say that core's
+// structural projection cannot. The raid alert does — it is the one message
+// here somebody acts on at 3am, and it must say WHERE and WHAT in the first
+// line. The wipe does — it is the one broadcast a whole community waits for.
+// Everything else is "this happened, here is the link", which is exactly what
+// core's `notify.event` / `inapp.event` already say, so it points at those and
+// authors nothing (§4.6.1 property 1).
+//
+// The register is plain, not in-universe. Rust has no court or herald to write
+// in the voice of, and a raid alert dressed as fiction is a raid alert read a
+// second later than it should be.
+//
+// ── Three rules for editing a body ────────────────────────────────────────
+//
+//   1. **No conditionals, and never an optional inside a clause.** An unset
+//      optional interpolates to the EMPTY STRING. `atGrid` is a fragment that
+//      carries its own leading space for exactly that reason; `grid` on its own
+//      belongs on a line of its own or nowhere.
+//   2. **No brand.** `siteName` and friends are supplied by the renderer, so one
+//      image mails as whichever site it is running as.
+//   3. **Bump `seedVersion` when a body changes, never for a comment.** It is how
+//      a better default reaches deployments whose operators did not edit it.
+//
+// ── One rule group per family ─────────────────────────────────────────────
+//
+// A group is seeded ONCE (per deployment, per key), so a rule appended to a
+// group in a later version reaches fresh installs only. Eight families, eight
+// keys: a future raid rule takes `raid-v2` without disturbing anybody's clan
+// rules. Every rule is disabled — core ignores `enabled` rather than trusting it
+// — so installing this module mails nobody until an operator decides it should.
+

+//
+// The payload contracts behind every notification this module can cause
+// (MODULE_API.md §2.4, `registerEventTriggers`; PLAN.md §25). A trigger says
+// what an event IS, what a template may interpolate, and — the part that is a
+// security boundary — the widest audience a rule on it may EVER be given.
+//
+// ── The ceiling is containment, not size ──────────────────────────────────
+//
+// `owner` is not a small `staff`, and `staff` does not permit `owner`. For the
+// raid alert "one person" is the person whose base it was; for a ban it is
+// nobody outside the staff room. Each ceiling below is chosen against that
+// lattice and not against a ladder, and core refuses a rule that widens one.
+//
+// ── What no variable here carries, on purpose ─────────────────────────────
+//
+//   • An IP address. The login and ban frames carry one; the triggers do not,
+//     so no template an operator writes can put an address in a mail. The
+//     admin feed still shows it, to staff, where it is useful.
+//   • The raider (D66). The raid alert says what was destroyed, where and
+//     when. Who did it is gameplay intelligence the game does not hand the
+//     victim, and a variable that is not declared cannot be interpolated.
+//   • A Steam id other than the subject's own.
+//
+// ── Why `subjectKey` is what it is ────────────────────────────────────────
+//
+// Core's cooldown is per (rule, user, subject, channel). So the subject is the
+// thing a recipient should hear about once per cooldown: a BUILDING for a raid
+// (however many walls fall), a SERVER for a broadcast (however often it
+// bounces), a CLAN for a membership change. A subject that changed every firing
+// — a boot id, a timestamp — would make every cooldown a no-op.

+// ── What an event may BORROW on a Rust server (PLAN.md §27, protocol 8) ─────
+//
+// The module never takes a lease and never bounds one. An author puts core's
+// `core.lease` in a step naming a lease, a target, a value and a number of
+// minutes; core reads the baseline, reserves `<lease id>#<target>` against the
+// two-events-one-target index, applies the value with its deadline and restores
+// it at teardown. What is here is the four callables each lease ships, and the
+// option sources that fill its target field.
+//
+// ── The target names the server (D73) ─────────────────────────────────────
+//
+// `core.lease` hands a lease only `{ target }` — never the run's scope — and
+// reserves `<id>#<target>`. So every lease here is TARGETED and every target
+// begins with the server id: `srv-a` for a single value, `srv-a/bear.population`
+// or `srv-a/default/kits.vip` for a family. That makes the ledger's unique index
+// bite at exactly the granularity Rust has: two runs on two servers never
+// collide, and one value on one server has one holder.
+//

+// plugin holds the allowlist, the bounds, the seven-day ceiling and the deadline

+// something they can redeem, and can tell the server. Four verbs:
+//
+//   rust.participation.open     the game starts counting who takes part (D81)
+//   rust.participation.collect  core files the count as the run's participants
+//   rust.kit.entitle            the right to redeem a kit, and one more use of
+//                               it (R16, D103), for the people a mode picks
+//   rust.announce               one line in a server's chat, or every server's
+//
+// …and the announce leg, `rust.chat`, which says a published news post in the
+// chat of every server whose switch is on (D104).
+//
+// Phase 17 gave both a delivery — chat, or a popup through PopupNotifications
+// (D141, D142) — and a VOICE: the style of one permission group, which the
+// plugin says the line in with no player as its sender (D140).
+//
+// ── Who decides what ─────────────────────────────────────────────────────────
+//
+// The GAME counts: presence, kills, the score (D81, D99). The SITE picks the
+// recipients and holds the reward: the tally is read, a mode chosen per event
+// picks from it (D101), and a row per recipient goes into
+// `rust_perm_run_grants`, which the permission mirror pushes like any other
+// grant (D84). So a reward granted at 03:00 to somebody offline is waiting when
+// they next log in, and a wipe cannot take it away: the site re-pushes it.
+//
+// ── An action is never handed the participants ──────────────────────────────
+//
+// Core records participants from `collect`'s answer, but does not give them to
+// a later step. So `kit.entitle` reads the tally from the plugin itself, as
+// `uo.item.grant` reads it from the shard, and does not depend on a collect step

+//
+// A lease borrows a value that was already there. These three verbs make
+// something that was not — a zone, crates, NPCs — and
+// give it back at teardown. Everything that decides what is allowed lives on the
+// plugin: the allowlist, the bounds, the monument vocabulary, the registry of
+// what each run owns. What is here is the contract's half: declarations core can
+// check an author's step against, and the three callables core calls.
+//
+// ── Four facts from the rig shape all of it (§28.1) ──────────────────────────
+//
+//   * A restart is NOT proof a placed thing is gone. Crates are saved by the
+//     game and come back with the same net id; NPCs are not. So `reconcile` asks
+//     the plugin, which looks — `module-uo`'s `reconcileByBootId` trick would
+//     orphan every crate on every restart.
+//   * A wipe IS proof everything is gone, and the plugin drops its registry.
+//   * The bridge has no at-most-once store, so its registry is keyed by core's
+//     idempotency key: a retried step is answered with the first call's ids.
+//   * Monument names repeat, so a monument is named by kind and instance (D93).
+//
+// ── The ref names the server ─────────────────────────────────────────────────
+//
+// Every resource is `<serverId>:<id>`. `revert` and `reconcile` are handed

+// is the only place the server can travel with the thing.

+// One job: move each server's cursor forward, and apply what it passed.
+//
+// ── Why a cursor and not a socket ─────────────────────────────────────────
+//
+// The obvious design is a WebSocket — the sidecar has one, and module-uo takes
+// exactly that route for the UO bridge. This module polls a cursor instead, and
+// the reason is not laziness about latency.
+//
+// Core runs on Node 20, where a global `WebSocket` is still behind a flag, so a
+// socket means taking `ws` as a runtime dependency — and this module's release
+// asserts that it has none (D5: everything it needs arrives on `ctx`, and the
+// bundle ships no `node_modules`). That is a cost worth paying for latency, but
+// the deciding argument is the other one: **a socket needs a cursor anyway.**
+// Whatever a feed misses while a module is restarting has to be caught up from
+// somewhere, and the catch-up path is the one that must be right. A socket on
+// top of a cursor is two mechanisms where the second is load-bearing; a cursor
+// alone is one mechanism that is exercised every few seconds rather than only
+// after an outage nobody planned.
+//
+// What it costs is seconds of latency on a killfeed. What it buys is that the
+// path which recovers from a five-hour outage is the same path that ran a moment
+// ago.
+//
+// ── The ordering the whole thing rests on ─────────────────────────────────

+// ── The map's picture: noticing a new map and fetching it ─────────────────
+//
+// R9's first half, as the rig rewrote it (PLAN.md §30.0). The picture is not
+// extracted from anything: the game's Rust+ service already holds a JPEG of the
+// map in memory, and the plugin hands it over in 512 KiB slices. That changes
+// the one rule R9 carried over from the asset bridge, where a fetch was an
+// expensive extraction:
+//
+// **D110 — the site fetches the picture BY ITSELF the first time it sees a map
+// it does not have**, because reading the cache costs the game nothing. It is
+// triggered off the board poll (`boot.js`): a new boot, wipe, seed or world
+// size, or a server with no row at all, is a reason to ask `map.info`, and a
+// key or hash that differs from the row is a reason to fetch.
+//
+// **D109 — a render is never automatic.** A server with no Rust+ cache has no
+// picture until an admin presses Render now, which stalls that game for seconds
+// and is said so beside the button. The render answers at once and happens on a
+// later frame; this file then polls `map.info` until the picture exists and
+// fetches it like any other.
+//
+// Three rules the fetch keeps:
+//
+//   • **One fetch per server at a time**, held here. A second trigger while one
+//     runs is dropped, and an admin's Fetch again is told one is running.
+//   • **A fetch that straddles a map change is abandoned whole.** The plugin
+//     refuses a slice with `stale` when the key or hash moved, and the bytes are
+//     checked against the hash before anything is written: two maps are never
+//     spliced, and a half-fetched picture is never stored.
+//   • **A failure keeps the old row** and retries on a backoff. The page keeps
+//     drawing the last picture it had, which is still the right map until the
+//     key says otherwise.

+// ── The map: who may see which layer, and what a viewer is sent ───────────
+//
+// R9's security boundary, and the reason this file exists apart from the
+// picture machinery in `mapImages.js`: **public player positions in Rust locate
+// players, and base positions are where they sleep.** So every layer has its own
+// audience (D112), a fleet default with a per-server override (D114), and a
+// viewer is SENT only the layers they may see — a hidden layer is absent from the
+// answer, never present and hidden by the page (§30.2).
+//
+// ── The four layers ───────────────────────────────────────────────────────
+//
+//   world     monuments, and the world's own events: cargo, the patrol
+//             helicopter, the Chinook, Bradley, supply drops, locked crates
+//   events    what this site's events placed: zones, crates, NPCs (phase 13a)
+//   players   who is on the server and where, and the sleepers
+//   bases     tool cupboards and player vending machines, as positions only
+//
+// Defaults: the first two public, the last two staff. The audiences are the
+// presence rungs (`staff` · `signed_in` · `public`) and follow its asymmetric
+// fallbacks: an unknown stored word narrows to staff, an unknown viewer is
+// public (`model/visibility`).
+//
+// ── Two rules that make the players layer safe to widen ───────────────────
+//
+// **D113 — it can never show more than presence does.** Its effective audience
+// is the NARROWER of the layer's switch and the server's presence audience. An
+// operator who opens the map to the public while the roll call stays staff has
+// opened nothing: a name on a map says who is online as surely as a list does.
+//
+// **D115/D117 — own dot and clan mates.** A linked viewer sees their own
+// position (their sleeper too, §30.5) and their ONLINE first-party clan mates on
+// that server, whatever the players layer says — and only a linked member of the
+// same clan sees them. It is gated by its own switch (D118, default on) and by
+// nothing else: widening the roster widens who sees the member LIST, never where
+// the members are.

+// ── SQL for the permission mirror, and nothing else ───────────────────────
+//
+// The tables this file reads are described at length in `db/schema.sql`; what
+// matters here is which of them is authoritative for what, because several look
+// similar and answer completely different questions:
+//
+//   AUTHORED   the site's own record of every permission and group on every
+//              server (D160). Groups are `rust_permgroups` and the rows beside
+//              them — one group per server unless an admin shares it (D189).
+//              Holders are website users (`rust_perm_grants`,
+//              `rust_permgroup_members`, D28) or single Steam accounts
+//              (`rust_perm_steam_grants`, `rust_permgroup_steam_members`, D188),
+//              and a grant that reaches several servers may carry exceptions
+//              (`rust_perm_exceptions`, D190).
+//   PUSHED     `rust_perm_pushed` — what this site has confirmed into one game's
+//              store. Keyed by STEAM ID, because it records what is in the game
+//              and the game has never heard of a website account.
+//   FOUND      `rust_perm_drift` — a change made in the game that waits for a
+//              person: every one under the `adopt` policy, and the few no policy
+//              can settle alone (D161, D190).
+//   INSTRUCTED `rust_perm_revocations` — remove this, even though we never put
+//              it there.
+//
+// Raw parameterised SQL through `core.query`, no ORM, like every other `.db.js`
+// here. Bulk writes are batched into one statement with a generated placeholder
+// list rather than looped, because a fleet-wide sync writes hundreds of rows and
+// a round trip each is how a boot tick becomes a second long.

+// ── The authored set, and what it means for one server ────────────────────
+//
+// This file turns "what the site holds" into "what one game server's store
+// should contain". Since the permission manager was rebuilt (PLAN_REDESIGNS §1)
+// the site holds EVERYTHING on every server — what was there before it, what an
+// admin made, and what was changed in the game (D160) — so the decisions that
+// live here are:
+//
+//   D28   a grant or membership held by a WEBSITE USER reaches every Steam id
+//         they have linked, resolved here at the moment of the push.
+//   D188  one held by a STEAM ACCOUNT reaches exactly that account, linked or not.
+//   D29   a grant carries a scope — one server, or `*` for the fleet — and a
+//         server sees only what names it. D190 lets a fleet grant carry
+//         exceptions: "every server except this one".
+//   D189  a group belongs to one server unless an admin shares it. What it
+//         carries and who is in it are the group's, and the same on every server
+//         it is on.
+//   D31   the difference between the desired set and what this site has pushed
+//         is what gets retired.
+//
+// `buildDesired` also says, for each row, which authored rows produced it (its
+// SOURCES). The reconciler needs that to answer a change made in the game: a
+// grant removed in the game is deleted when it was this server's alone, and gains
+// an exception when it reached further (D190).
+//
+// Nothing here talks to a sidecar — `permSync.js` does that — and nothing here
+// writes: every function below is a pure function of rows, tested without a
+// game, a sidecar, or a database.

+// ── Three sets, and what a change made in the game becomes ────────────────

+// `rust_perm_pushed`'s own comment has always named three sets — what is in the
+// game, what this site put there, and what the site wants there. Until protocol
+// 13 the plugin could only compute the first for the names the site claimed.
+// The inventory (PLAN_REDESIGNS §1.2) gives the site all three, so the whole of
+// "what happened, and what do we do about it" is decided here:
+//
+//   in the game   pushed   desired   means
+//   yes           no       no        ADDED in the game
+//   no            yes      yes       REMOVED in the game
+//   yes           yes      yes       a group whose title, rank or parent the
+//                                    game holds differently from what was
+//                                    pushed: CHANGED in the game
+//   yes           no       yes       landed by some other hand: recorded
+//
+// (desired − pushed is the ordinary push, and pushed − desired the ordinary
+// retirement; neither is this file's business.)
+//
+// Then the server's policy (D161) says what each change becomes: the site's own
+// (`auto-adopt`, the default), a question for a person (`adopt`), or undone
+// (`revoke`). The first inventory of a server imports what it finds whatever the
+// policy (D198).
+//
+// **Two things are never judged, and both are how a site would otherwise throw
+// away its own grants.** A permission the server has not REGISTERED right now —
+// a plugin unloaded for a minute — is missing from the inventory because the
+// plugin that owns it is, not because anybody revoked it. And a group permission
+// an event lease holds is the lease's until it ends.
