 # `module-rust` — the plan
 **Status:** approved in outline 2026-09-15, not started. **Eighteen decisions of record, no open
 questions.** Audited against the whole contract, not just the game-facing chapters (§7); the event and
 engagement catalogues are §9 and §10.
 The [dry run](../rust-dryrun.md) designed this module on paper and deliberately did not build it.
 This is the document that builds it. Where the two disagree, this one is later and wins — but the dry
 run's four *findings* still stand, and one of them (identity) has moved from a footnote to the
 critical path. §2 says why.
 Nothing here is normative. [`MODULE_API.md`](../../website/MODULE_API.md) is the contract,
 [`MODULE_SYSTEM.md`](../../website/MODULE_SYSTEM.md) the system, [`EVENTS.md`](../../website/EVENTS.md)
 the event design of record, and the [Integration Kit][kit] is the teaching text this plan follows
 chapter by chapter. This document is a *schedule and a set of decisions*, not a specification.
 ---
 ## 1. The shape, and what is already settled
 Three new repositories, mirroring the three the platform already has for Ultima Online, plus the
 optional fourth part that lives inside the module:
 | Part | Repo | Mirrors | What it is |
 |---|---|---|---|
 | Website module | [`RunicGateway/Module-Rust`](https://gitea.whitlocktech.com/RunicGateway/Module-Rust) | `Module-uo` | Routes, schema fragment, prebuilt client chunk, nav |
 | Sidecar | [`RunicGateway/Rust-Link`](https://gitea.whitlocktech.com/RunicGateway/Rust-Link) | `link` | Owns the game connection and the durable copy |
 | Oxide bridge plugin | [`RunicGateway/Rust-Plugins`](https://gitea.whitlocktech.com/RunicGateway/Rust-Plugins) | `servuo-plugins` | C# inside the game, dials out, never blocks |
 | *(event capability)* | — | — | Declarations inside `Module-Rust` ([kit][kit] ch. 5) |
 All three were created empty on **2026-09-15**. The module is built from
 [`integration-kit/template/`][kit], which CI holds against a pinned core — currently
 `MODULE_API_VERSION` **1.10.0**.
 **The repository name is not the module id.** `Module-uo` ships a module whose `id` is `uo`; this one
 ships `rust`. §2.1 of the contract requires `id` to equal the directory core loads it from, which is
 `modules/rust/`, and it is the prefix of every table and every mount — so the capitalisation in the
 repository name reaches nothing inside the bundle.
 Settled before this document and unchanged by it (dry run, org lead, 2026-08-19):
 - **One server, one sidecar**, on that server's own host. A community with six servers runs six
  pairs; the module holds six clients and core never learns there is more than one.
 - **The plugin dials out.** Rust's server is a binary, so the way in is Oxide's published hook API
  rather than source — and the shard-dials-out invariant survives that change of footing unchanged.
 - **No RCON.** It was the original design and it was overruled.
 - **`wipe_id` on every table that holds gameplay data.** It is the whole shape of the game in one
  column, and it is the first thing a UO-shaped mental model gets wrong.
 ## 2. Decisions of record
 ### R1 — identity is an in-game link code for v1
 **Decided 2026-09-15 (org lead).** A player proves account ownership by typing a command in-game; the
 plugin issues a one-time code; the website confirms it through the sidecar. Exactly the shape
 `module-uo` uses.
 This is the dry run's finding 1 answered for now rather than closed. There is still **no
 `registerAuthProvider`** in the contract at 1.10.0 — verified against `MODULE_API.md` §2.4 on
 2026-09-15 — so "Sign in with Steam", which every Rust community expects, is not reachable from a
 module today. The link code is one screen worse and needs no core change, so it is what v1 ships.
 **What changed since the dry run is the stakes, not the options.** The dry run rated this survivable
 because the module only *read*: a site that renders a leaderboard does not need to know which account
 owns a Steam ID. R2 makes the site the author of who may do what in the game, and R3 makes it the
 thing that hands out loot. Both are grants against a Steam ID. **A weak identity link is now a
 privilege-escalation path, not a missing convenience** — so the code must be single-use,
 short-lived, rate-limited, and issued in-game to the player who will own it.
 Adding `registerAuthProvider` properly stays the first candidate for a future `MODULE_API` bump. It
 participates in session creation, which is the one part of core a module must never be able to
 weaken, and it must inherit core's existing policy: **SSO is link-only, identities are never
 auto-provisioned.** Specified deliberately, not bolted on. It is out of scope here.
 ### R2 — site-authored permissions are mirrored into Oxide's own permission store
 **Decided 2026-09-15 (org lead).** The website is the author of record for groups and grants. The
 bridge plugin applies them through Oxide's own API (`permission.GrantUserPermission` /
 `RevokeUserPermission`), so **Oxide is an enforcement cache and the site is the thing that
 remembers.**
 The alternative — the plugin keeping a private table only our own features consult — was rejected
 because it cannot reach any third-party plugin, and reaching them is the point: a grant authored on
 the site has to gate Kits.
 Three properties fall out, and they are the reason this shape is worth its cost:
 - **Every third-party plugin honours site-authored grants with no adapter**, because they all already
  call `permission.UserHasPermission`.
 - **A wipe stops being a data-loss event for permissions.** The game forgets; the site does not, and
  re-pushes the whole set on the next connect.
 - **Hand edits are reported, not overwritten.** Somebody typing `oxide.grant` at the console is
  drift, and drift is surfaced to an operator — the same posture a lease's `restore()` takes when it
  finds a value a human has moved ([kit][kit] ch. 5).
 **This is a direction the Integration Kit has no chapter for, and that is a finding.** Chapters 3 and
 4 are the read path — data leaving the game. Chapter 5 is one-shot commands with a ledger and a
 teardown. This is neither: it is *continuously reconciled state where the website is authoritative*,
 and its nearest relative in the contract is the Team provider **inverted** — instead of core asking
 the module what the game knows, the module tells the game what the site knows. The mechanism it
 borrows is chapter 4's: **every board's current state has exactly one producer, and it runs on
 connect**, pointed the other way. Whether this deserves a sixth chapter is a question for phase 19,
 after it has been built once.
 ### R3 — the Kits reward action registers always and refuses with a reason
 **Decided 2026-09-15 (org lead).** Kits is required for event rewards, but "required" means the
 action always exists and fails honestly where it cannot work — `{ ok: false, retry: false, error:
 'Kits plugin not installed' }` — rather than vanishing from the authoring form or refusing to boot
 the module.
 Two details from [kit][kit] ch. 5 that this depends on and are easy to get wrong:
 - **The reason must be in `error`.** Core reads exactly `ok`, `retry` and `error` off a failure
  envelope; a message under any other name is dropped and the operator sees a bare
  `"<action id> refused"`.
 - **`retry: false` has to be reachable.** Core's dispatcher enforces `budgetMs` and classifies a
  budget timeout as retry *unconditionally* — so if the sidecar client's timeout is longer than
  `budgetMs`, our own `retry: false` is unreachable code. Derive one constant from the other and
  assert the inequality in a test. The first module this project shipped had exactly that pairing.
 ### R4 — Rust reaches an operator through the existing installer, behind `--game`
 **Decided 2026-09-15 (org lead).** Not a second binary and not a shared-core refactor: the shipped
 [`installer`](../../installer/PLAN.md) grows a game dimension, `--game servuo|rust`, and keeps one
 release stream, one `doctor`, one `update`, one `uninstall`.
 The shape of the work is set by where the coupling already is. **The reusable half is already
 game-agnostic** — `src/service.rs` and `src/main.rs` mention ServUO zero times, and `net.rs`,
 `diff.rs`, `paths.rs` and `ui.rs` barely more. **The UO-specific half is concentrated in four files**
 — `install.rs`, `doctor.rs`, `overlay.rs`, `tier.rs` — plus the bundle manifest, where
 `OverlayComponent` and `ServUoCompat` name the game in the schema itself.
 So the change is: make the bundle's game payload a **variant** rather than an overlay, and
 `ServUoCompat` a per-game compat block. That is a schema change on the published **`bundles`**
 branch, and it is the part to design before touching code.
 **The Rust payload is much simpler than the UO one**, which is what makes this affordable: no source
 tree to overlay, no `patches/`, no opt-in patch tier — a Rust install is a `.cs` file dropped into
 `oxide/plugins/`, plus the sidecar and its service, which the installer already knows how to do. What
 it gains instead is a **prerequisite check**: is Oxide installed, and is its build current enough.
 That is `doctor`'s shape, not a new concept.
 The protocol pairing check generalises unchanged. `servuo-plugins/overlay.toml` declares the protocol
 the overlay speaks and the installer refuses to pair a disagreeing sidecar; `rust-plugins` needs the
 same declaration under whatever name the variant gives it, and the refusal is the same refusal.
 ### R5 — Teams come from Rust's first-party clans; the uMod Clans plugin is the richer tier
 **Decided 2026-09-15 (org lead).** Basic functionality is built on **Rust's own clan system**; the
 third-party **uMod Clans plugin** is an optional layer for a much richer experience, and lands in
 phase 17 rather than phase 9.
 The distinction matters more than the names suggest, so it is worth stating precisely:
 - **Rust's first-party clans** are seven hooks in [`HOOKS.md`](HOOKS.md) — `OnClanCreated`,
  `OnClanDisbanded`, `OnClanMemberAdded`, `OnClanMemberKicked`, `OnClanMemberLeft`, plus colour and
  logo — each handing you a `LocalClan`. **All seven are "no return behavior"**, which is exactly
  what a read-only bridge wants: there is nothing to abstain from, so [kit][kit] ch. 4's
  return-`null`-from-every-veto rule has no work to do here. They need no plugin, and the rig is
  already running them (`D:\rust\server\server1\clans.287.db`).
 - **Rust's first-party *Teams* are a different system** — twelve hooks, mostly vetoable — and are the
  transient in-game squad, not the persistent organisation. They are **not** what core's Team
  provider should be fed. Clans is the right choice and this is why.
 - **The uMod Clans plugin's API is not in our mirror.** [`HOOKS.md`](HOOKS.md) is the *game's* 477
  hooks; a plugin's own API is its own documentation. It is reached through `[PluginReference]` and
  is null when absent, making it an R3-shaped dependency that must refuse with a reason.
 **Reading that plugin's source settled R5 far more firmly than the reasoning above did, and in a
 direction worth stating plainly: for Teams, the plugin is *worse* than first-party, not richer.**
 `Clans` v0.2.10 (k1lly0u, MIT, 2,692 lines) publishes **fifteen `[HookMethod]`s and every one of
 them is a mutation** — `CreateClan`, `JoinClan`, `LeaveClan`, `KickPlayer`, `PromotePlayer`,
 `DemotePlayer`, `DisbandClan`, and the eight alliance verbs. **There is no read API whatsoever**: no
 `GetClan`, no `GetClanOf`, no `GetClanMembers`, no `GetAllClans`. And it raises exactly **three**
 hooks — `OnClanCreate`, `OnClanChat`, `OnAllianceChat` — **none of which is a membership
 transition**.
 So it cannot answer any of core's three provider questions from its published surface, while
 first-party clans answer all three. Feeding the Team provider from first-party clans is therefore
 **permanent, not a first step**.
 What the plugin genuinely adds is **alliances and clan/alliance chat** — richer in *features*, not in
 roster data. That is what phase 17's adapter surfaces, and it sits beside the Team provider rather
 than under it.
 One route is deliberately not taken: the plugin persists to its own files under `oxide/data/`, and a
 determined integration could read those directly. **That is reaching into another plugin's private
 storage, not using an API** — it breaks without warning on any upstream refactor and is not a
 contract anybody owes us. If phase 17 wants roster data from the plugin, the honest path is an
 upstream pull request adding a read method, not a file reader.
 ### R6 — the required base set: Kits, Clans, PopupNotifications and ZoneManager
 **Named 2026-09-15 (org lead), extended the same day by R17.** All four are MIT; three are k1lly0u's
 and BetterChat's author differs only in the optional tier. All fetched at plan time:
 | Plugin | Version | Released | Source |
 |---|---|---|---|
 | [Kits](https://umod.org/plugins/rust-kits) | 4.4.9 | 2026-06-04 | `https://umod.org/plugins/Kits.cs` |
 | [Clans](https://umod.org/plugins/clans) | 0.2.10 | 2026-05-06 | `https://umod.org/plugins/Clans.cs` |
 | [PopupNotifications](https://umod.org/plugins/popup-notifications) | 0.2.1 | 2026-08-09 | `https://umod.org/plugins/PopupNotifications.cs` |
 | [ZoneManager](https://umod.org/plugins/zone-manager) (R17) | 3.1.14 | 2026-09-02 | `https://umod.org/plugins/ZoneManager.cs` |
 Every one has a direct `.cs` download, so phase 0's install step is four `curl`s into
 `oxide/plugins/` and no manual retrieval. **Pull them fresh rather than using the copies staged in
 `Downloads`**, which are an older vintage.
 **The four base plugins use three different conventions for their callable API**, which is worth
 knowing before someone goes hunting for the wrong one: Kits uses `[HookMethod]`, BetterChat uses
 `API_`-prefixed methods, and ZoneManager uses plain private methods resolved by name. All three are
 reached the same way from our side — `[PluginReference]` plus `Call()` — but only the first is
 greppable as a declared API.
 `Clans` is listed by uMod as a **Universal** plugin rather than a Rust one — it is written against
 Covalence, and its API takes `IPlayer` rather than `BasePlayer`. That is the portable half of the
 uMod surface, and it is why the same plugin serves several games.
 **Kits is the opposite of Clans and is a genuinely good dependency.** Twenty-three `[HookMethod]`s,
 including the three things the event work actually needs:
 - `GiveKit(BasePlayer player, string name)` — the reward action's call;
 - `GetKitNames(List<string>)` / `GetAllKits()` — **the option source** for the authoring form, so an
  operator picks a kit from the live server instead of typing an identifier from memory;
 - `GetKitInfo` / `KitDescription` / `KitImage` / `KitMax` / `KitCooldown` /
  `GetPlayerKitUses` / `GetPlayerKitCooldown` — form metadata and per-player eligibility.
 It also **raises `OnKitRedeemed(BasePlayer player, string kitName)`**, which the bridge can listen on
 to report a redemption as an ordinary event, whoever triggered it.
 **Two traps in `GiveKit`, both found by reading it rather than by reasoning about it.**
 > **R16 moved these off the critical path.** The reward action no longer calls `GiveKit` — it grants
 > the kit's `RequiredPermission` and the player redeems it themselves. Both traps are kept here
 > because the second one is *why* R16 is the better design, and because anything that ever does call
 > `GiveKit` directly — an admin "give this player a kit now" button, say — walks straight into them.
 **`GiveKit` returns `null` on a failure path, and `null` is Oxide's idiom for "no opinion".** The
 first line is `if (!player) return null;`. Everywhere else in this ecosystem a null return means
 *abstain*, so the reflex — treat null as fine — reports a reward as delivered when there was no
 player to deliver it to. The success value is the literal `true`; a refusal is a **message string**,
 which drops straight into chapter 5's `error` field. So the mapping is
 `result is bool ok && ok` for success, a string for a refusal reason, and **`null` is a failure, not
 a success.**
 **`GiveKit` takes a `BasePlayer`, so the player must be connected.** There is no offline grant in
 this API. An event that rewards participants at two in the morning rewards only whoever is online at
 that moment, silently. The choice this forced was: accept online-only and say so in the action's
 description, or keep a persisted pending-grant queue in the bridge and redeem it on next connect —
 a second at-most-once store with its own idempotency, which is not free.
 **R16 took a third option and it is the right one: stop granting items.** Grant the entitlement
 instead. An entitlement waits without a queue, because waiting is what an entitlement does. The
 problem was not hard to solve — it was the wrong problem, produced by an action declared around the
 wrong noun.
 `PopupNotifications` is small and does exactly one thing: `CreatePopupNotification(string message,
 BasePlayer player = null, float duration = 0f)`, where a null player makes it global. That is the
 server-side notification surface, and it needs no more than that.
 **The one gap to design around:** the seven first-party hooks carry created, disbanded, added,
 kicked and left — but **no promote or leader-changed event**. Core's provider requires
 `getTeamLeaders`, so leadership is read off `LocalClan` at snapshot time rather than tracked from
 transitions. That makes phase 9 *partly* snapshot-driven where the dry run predicted it would be
 fully event-driven — a small correction to that document, recorded here rather than silently.
 ### R7 — the notifications and engagement set ships in v1
 **Decided 2026-09-15 (org lead).** `registerNotificationStreams`, `registerEventTriggers`,
 `registerAudiences` and `registerEngagementSeeds` are all in the first release, plus
 `registerAnnounceLeg` and `registerPostHook`.
 They are a **matched set**, which is why they are one decision and one phase: a trigger declares the
 payload contract and the widest audience a rule on it may ever be given, an audience resolves *people*
 over module data, and seeds ship the bodies and the rules that use them. Three rules from the kit
 that this phase lives or dies on:
 - **`ceiling` is required, has no default, and is not a ladder.** A `staff` ceiling does **not** permit
  `owner`, because "one person" for a cheat-detection event is *the player it was detected on*. Fewer
  people is not less exposure.
 - **`subjectKey` must name one of your declared variables** — it is what the cooldown keys on. Core
  refuses the module at boot if it names nothing, which is the good failure; the bad one it prevents
  is every subject sharing `undefined`.
 - **A rule group is offered once, per group key.** A rule appended to an existing group reaches
  **fresh installs only** — so a rule that must reach existing deployments takes a new group key.
 And the emit discipline: **emit on the transition, not on the poll.** Core's cooldown would hide a
 module that emitted "the server is still up" as news.
 ### R8 — multi-server from the start
 **Decided 2026-09-15 (org lead).** The server list is the landing page and everything else hangs
 under `/rust/servers/:id`. Every gameplay row carries a server id as well as a `wipe_id`, and the
 module holds one sidecar client per configured server.
 This is the dry run's finding 2 taken at face value: *"one module, one game" is not the same as "one
 module, one server"*. Retrofitting an `:id` segment through every route, table and page is the
 expensive version, and a Rust community runs several servers by default.
 ### R9 — the live map, with every layer toggleable
 **Decided 2026-09-15 (org lead).** The site offers a live map, and **each layer is an operator switch
 set to public / players-only / admin-only** through the existing visibility framework
 ([`SHARD_VISIBILITY.md`](../../website/SHARD_VISIBILITY.md)).
 **The map is two problems and they take different paths, which is the thing to get right before
 building either:**
 - **The map image is static content on the game host** — `proceduralmap.<size>.<seed>.<save>.map`
  beside the world save, regenerated only on a wipe. That is exactly [kit][kit] ch. 3 §2b's case, and
  it takes that shape: **request/reply, never events** (a sidecar that broadcast it would write
  megabytes into its own store and fan them at every client), **one in flight with an explicit busy**,
  **two stages — what exists, then what changed**, and a **derivation version** separate from the
  protocol so improving how we read the file invalidates a cached image whose source hash did not
  move. And **no import on boot**: a wipe is an event the operator knows about and the website does
  not.
 - **Everything moving on it is live state** down the ordinary read path — monuments, cargo ship,
  patrol helicopter, airdrops, locked crates, and player positions.
 **The layer switches are a security boundary, not a preference.** Public player positions in Rust are
 a competitive-advantage leak — anyone, including people who do not play on the server, could locate
 players and infer base positions. The default posture is monuments and world events public, player
 and base layers admin-only, and an operator opening one up is a deliberate act with the consequence
 stated on the switch.
 **This is the only asset-bridge work in scope.** Item icons and the 2,590 workshop skin ids stay out
 of v1; kill feeds and kit lists render as text.
 ### R10 — the Android app is in this workstream, capability-driven, trailing by one phase
 **Decided 2026-09-15 (org lead).** Full Rust support in the app, not a degradation check. It decides
 which screens to show from **`GET /api/v1/public/modules`** — each started module's `capabilities`
 array — and each app leg lands **one phase after** the website surface it consumes is merged, so it
 is always built against a real endpoint rather than a planned one.
 Two endpoints that are *not* this and are easy to confuse with it, both checked on 2026-09-15:
 `/api/v1/public/status` returns site mode plus a version block — the first-run probe and
 version-mismatch guard, not a feature manifest — and `/api/health` on the internal app is a liveness
 probe returning `{status:'ok'}`. Neither can say which pages exist.
 §2.9's rule governs: **treat an unknown capability as absent, and never infer a URL from one.**
 ### R11 — a small read-only set of Discord slash commands
 **Decided 2026-09-15 (org lead).** Questions answered from data the module already holds — server
 status, wipe schedule, leaderboards, who is online. No write verbs, and the account link stays on the
 two surfaces R1 names rather than acquiring a third.
 The trap to carry in from the Teams work: **ephemerality is fixed at the deferral**, so a command
 that might refuse must defer ephemeral or its refusal goes public in the channel. And the registries
 have no removal path, which is an argument for adding a command late rather than early.
 ### R12 — per-wipe detail plus all-time rollups
 **Decided 2026-09-15 (org lead).** Every gameplay row carries `wipe_id`; leaderboards default to the
 current wipe; a separate rollup accumulates per player across wipes so a returning player's history
 survives the monthly reset.
 The truncation is a **runtime operation on a module route, never a schema one** — §2.6's leading-verb
 allowlist forbids `DELETE` and `TRUNCATE` in a fragment precisely because the fragment replays at
 every boot and would empty the table on each restart.
 ### R13 — two extension slots: `admin.users.detail` and `site.footer.status`
 **Decided 2026-09-15 (org lead).** An operator looking at a user sees their linked Steam identity,
 per-server stats and site-authored permission grants in core's own admin user page; the footer
 carries a shard-status indicator on every page.
 One module per slot, so claiming them also reserves them. And the naming rule matters for anyone
 reading this later: **a slot is named for a PLACE, never for a meaning** — `site.footer.status` is
 "the status-ish spot in the footer", not core knowing what a game server is.
 ### R14 — `/rust` on all three tiers
 **Decided 2026-09-15 (org lead).** `public`, `admin` and `player` all mount `/rust`, exactly as
 `module-uo` mounts `/uo`. Sub-surfaces are path segments: `/rust/servers/:id`, `/rust/map`,
 `/rust/clans`.
 Chosen deliberately because **prefixes share one namespace with core's own and the loader's collision
 probe cannot see all of core's** — several core endpoints are mounted at the tier root rather than
 under a prefix. A noun from our own domain that equals the module id cannot collide, where
 `/servers` or `/map` very well might.
 ### R18 — plugin configuration is editable from the site, with a generated form and an auto-reload
 **Decided 2026-09-15 (org lead).** An admin edits any loaded plugin's configuration from the website
 and it reloads automatically. Two tiers:
 - **Base:** the site walks `oxide/config/` **recursively** and **generates a form from the values
  themselves** — a boolean becomes a toggle, a number a numeric field, a string a text box, an array
  a list, a nested object a group. It is derived at read time, so **it works for whatever plugins
  happen to be installed**, including ones added or removed after we shipped.
 - **Advanced:** raw JSON editing for anything the generated form cannot express.
 This is the same posture as R2 — the site as the authority over the game host — but a different
 *shape*. R2 is continuously reconciled state pushed on every connect; this is **request/reply,
 on demand** ([kit][kit] ch. 3 §2a). Do not build it on the permission mirror.
 **The mechanics Oxide gives us, all verified 2026-09-15:** configs live at
 `oxide/config/<PluginName>.json`; `oxide.reload <name>` rereads one; and **`OnPluginLoaded` /
 `OnPluginUnloaded` are real hooks** in the Server category, so *whether a reload actually succeeded
 is observable* rather than assumed.
 #### Discovery is a recursive walk, and it stops at `oxide/config/`
 **Amended 2026-09-15 (org lead).** Configuration is **not** one flat `oxide/config/<Plugin>.json` per
 plugin. Plugins nest — `oxide/config/<Mod>/whatever.json`, and deeper — and one plugin may own
 several files. So discovery is a **recursive walk** of the config tree, and the UI groups by plugin
 rather than assuming one file each.
 Four things follow, and the first is a boundary rather than a detail.
 **`oxide/data/` is not the settings surface, and must not be walked into.** `DataFileSystem` writes
 to `oxide/data/`, and that is **live state, not configuration**. The base set makes the point by
 itself: Kits keeps `Kits/kits_data.json` and `Kits/player_data.json`, ZoneManager keeps
 `ZoneManager/zone_data.json`, Clans keeps `clan_data.json` (and a legacy `clans_data.json` beside it,
 which is also a reminder that these names are not stable). Editing those from a web form edits
 **players' kit cooldowns and the live zone definitions**, a running plugin overwrites the change on
 its next save, and `oxide.reload` does not make most plugins safely re-read them. It is a different
 problem with a different answer and it is deliberately out of scope. If a plugin's *settings* genuinely
 live under `data/`, that is a per-plugin exception someone opts into knowingly, never something the
 walk discovers on its own.
 **The reload target cannot be inferred from the path.** `oxide/config/Foo/bar.json` may belong to
 plugin `Foo`, or to something else entirely — the folder name is convention, not contract. So the
 reload target is an **explicit field with the folder name as its default guess**, confirmable by the
 admin. Infer it silently and the failure is the nastiest kind available here: we reload the wrong
 plugin, observe `OnPluginLoaded` for *it*, and report success while the plugin that was actually
 edited never re-read anything.
 **A relative path from a web form is now a path-traversal surface.** Canonicalise the resolved path,
 assert it is genuinely under the config root, reject absolute paths, and reject symlinks that resolve
 outside. Before this amendment the feature addressed files by plugin name; now it addresses them by
 path, and that is exactly the change that introduces the bug class.
 **Bound the walk and the file.** A depth limit, a file-count limit and a per-file size cap — a
 pathological tree must not be enumerated and a multi-megabyte JSON must not be loaded into a form.
 And because one plugin can own several files, **the backup and rollback operate on the whole set a
 save touches**, not one file at a time.
 #### The trap that would silently corrupt every float
 **JavaScript cannot tell `1` from `1.0`, and Oxide configs deserialize into typed C# classes.**
 `JSON.parse('{"Rate":1.0}')` yields the number `1`, and `JSON.stringify` writes it back as `1` — so
 a naive read-modify-write of a config file **silently rewrites every whole-numbered float as an
 integer**, on fields nobody touched. Newtonsoft may coerce it, or may throw, and a throw at load
 means the plugin does not come back.
 So: **never parse the whole document, mutate, and re-serialize.** Edit the file *textually* — a
 surgical replacement of the edited key's value — or use a parser that preserves number literals. The
 fields at risk are exactly the ones a Rust server tunes: gather rates, multipliers, scales.
 #### Five more limits of inferring a schema from values
 Worth stating because the feature's whole promise is that it works without knowing the plugin:
 - **Empty arrays and `null` carry no type.** Nothing can be inferred; render them advanced-only.
 - **Enum-like strings are indistinguishable from free text.** There is no allowed-value set to read,
  so a string field is a text box and cannot be validated.
 - **There are no descriptions, no minimums and no maximums.** The key name is the entire label —
  which is survivable because Oxide convention favours readable keys (BetterChat really does ship
  `"Maximal Titles"` and `"Reverse Title Order"`).
 - **Nested objects and arrays of objects need recursion**, a depth limit, and a fall-back to raw JSON
  past it.
 - **The file after a reload may not be what we wrote.** Oxide merges missing defaults and saves, so
  re-read after reloading rather than assuming our write is the current state.
 #### Safety, and why it needs more than the usual
 **A bad config does not fail the write — it fails the next load, and the plugin stays down.** Since
 R6 and R17 make four plugins *required*, a broken ZoneManager config takes event participation with
 it. So the write path is:
 1. Read with a **version** (hash or mtime) and require it back on write — an operator editing on
   disk at the same time gets a conflict rather than a silent overwrite.
 2. Validate the edited document parses.
 3. **Back up the current file**, write, reload.
 4. **Watch for `OnPluginLoaded` within a window.** If it does not arrive, **restore the backup and
   reload again, automatically**, and report the failure with whatever Oxide logged.
 That rollback is the feature's real content. Without it this is a web form that can take the shard's
 plugins down one typo at a time.
 **Two more obligations.**
 **Redact secrets.** Plugin configs routinely hold API keys and Discord webhooks. A config reader
 hands those to anyone who can open the page. Mask values whose key matches the usual shapes — key,
 token, secret, password, webhook — and treat them **write-only**, exactly as the platform already
 treats the uo-link token. This is a real leak vector and the generated-form approach walks straight
 into it.
 **Gate it on its own site permission and audit every write** — who changed which key, from what to
 what, and whether the reload succeeded. It is an admin writing to the game host's filesystem, which
 is the most powerful thing the site can do to a server.
 #### One distinction to keep
 **Editing a plugin's config file is not a lease.** A lease (§9) borrows a *convar* for a while and
 the game restores it on a deadline. This writes a *file* and is permanent until someone changes it
 back. They look similar from a web form and they are not the same mechanism — an event should never
 reach for this one.
 ### R17 — ZoneManager joins the required base set, because events need to know where people are
 **Decided 2026-09-15 (org lead).** **[ZoneManager](https://umod.org/plugins/zone-manager)** (k1lly0u,
 3.1.14 released 2026-09-02, MIT, Rust, ~218k downloads) is a fourth **required** plugin, not an
 optional one. It is what makes an event able to answer *where a player is*.
 Reading its source changed two things this plan had been vague about, and promoted one action out of
 the optional tier.
 **Its API is private methods reached through Oxide's reflection `Call()`** — no `[HookMethod]`, no
 `API_` prefix, which is a third convention among the four base plugins and worth knowing before
 someone goes looking for one that is not there.
 | Surface | What it gives an event |
 |---|---|
 | `IsPlayerInZone(zoneId, player)` → `bool` | the direct question |
 | `GetPlayerZoneIDs(player)` → `string[]` | every zone a player is in |
 | **`GetPlayerZoneIDsNoAlloc(player, List<string>)`** | the allocation-free variant — **the one to use on any sweep** |
 | `CreateOrUpdateZone(zoneId, args, position)` | make a zone |
 | **`CreateOrUpdateTemporaryZone(..., Plugin owner)`** | make a zone *owned by our plugin* |
 | **`EraseTemporaryZone(Plugin owner, zoneId)`** | remove one, **scoped to the owner** |
 | `GetZoneIDs` / `GetZoneName` / `GetZoneLocation` / `CheckZoneID` | the catalogue, for an option source |
 And nine hooks raised: `OnEnterZone` / `OnExitZone`, `OnEntityEnterZone` / `OnEntityExitZone`,
 `OnZoneInitialize` / `OnZoneUpdated` / `OnZoneDestroyed` / `OnZoneErased`, plus `CanSpawnInZone`,
 which is a veto our bridge abstains from like every other.
 **Three things this settles.**
 **Participation stops being the hard part.** [`EVENTS.md`](../../website/EVENTS.md) §H rates
 participation *"the hard part"* for UO and *"substantially easier"* for Rust because hooks carry
 attacker and victim. ZoneManager makes it exact rather than merely easier: `OnEnterZone` and
 `OnExitZone` are **presence transitions delivered as events**, so the participation ledger is fed
 from what happened rather than reconstructed from a sweep. An action's reply carries its
 `participants` envelope member, and this is where that member gets its content.
 **Advance conditions become expressible.** A phase that waits until *"ten players are at the
 monument"* is a real gate rather than a wish — it reads zone membership. Without ZoneManager the
 same condition is distance arithmetic against a point, recomputed on a timer, which is both more
 expensive and less accurate.
 **`rust.zone.open` moves from the optional tier into the base catalogue, and it can be
 `reversible: 'ledger'` honestly.** This is the nicer half: `CreateOrUpdateTemporaryZone` takes a
 **`Plugin owner`** and `EraseTemporaryZone` is **scoped to that owner**, so ZoneManager already has a
 first-class notion of a zone belonging to the plugin that made it. That is most of the persisted
 ownership registry [kit][kit] ch. 4 demands — we still keep our own map from core's resource
 reference to the zone id, but we are not inventing ownership, we are borrowing a concept the plugin
 already has. And erasing a zone that is gone is a success, which is what `revert` needs.
 **One trap to design against, and it is chapter 4's rule meeting a chatty hook.** `OnEnterZone` and
 `OnExitZone` fire on the game thread and a large zone with a busy server produces a great many of
 them. The emit path already enqueues and returns, so the game cannot stall — but **the bridge should
 subscribe selectively rather than forwarding every transition in every zone**. A zone no event cares
 about should cost nothing on the wire. Decide the filter with the hooks in front of you at phase 12,
 and measure it, because a sweep over `GetPlayerZoneIDsNoAlloc` is cheap and a flood of wire traffic
 is not.
 ### R15 — an optional-integration tier, with BetterChat as the first member
 **Decided 2026-09-15 (org lead).** Beyond the required base set (R6) the module carries a tier of
 **optional** integrations: each detects its plugin through `[PluginReference]`, degrades cleanly to
 absent, and adds something the site already knows how to compute.
 The first named member is **[BetterChat](https://umod.org/plugins/better-chat)** (LaserHydra, 5.2.15,
 MIT, Universal/Covalence, ~200k downloads) — *"manage chat groups, customize colors, and add
 titles"*. The motivating case is **titles earned from leaderboards**: top of the wipe's kill board
 gets a tag in chat.
 **Its integration point is a pull, not a push, and that is why it is a good first member.**
 `API_RegisterThirdPartyTitle(Plugin plugin, Func<IPlayer, string> titleGetter)` registers a callback,
 and BetterChat invokes it per player when it renders a chat line. So a leaderboard title is a *pure
 function of state we already hold* — nothing is written into BetterChat, nothing can go stale, and
 there is no drift to reconcile. Contrast R2, which is a push and needs a whole reconcile story.
 **The one trap, and it is chapter 4's rule applied to somebody else's callback:** that getter runs
 **synchronously on the chat path**. It must be a cheap in-memory lookup — never a socket call, never
 a database query, never anything that can block. A title that costs a round trip is a chat message
 that costs a round trip.
 Its other two API methods, `API_AddGroup(group)` and `API_SetGroupField(group, field, value)`, pair
 naturally with R2: the site already authors permission groups, so a site-authored group can carry a
 chat colour and tag. That is a push and would need the same drift posture R2 has; it is a phase-17
 decision, not a given.
 **The tier is open-ended by design.** Other integrations get added as they prove useful, and the bar
 for each is the one this plan applies everywhere: it must fulfil the contract — declare honestly,
 degrade to absent, and never make the module's own surfaces depend on something that may not be
 installed.
 ### R16 — the reward action grants the RIGHT to redeem, not the items
 **Decided 2026-09-15 (org lead).** An event reward does **not** call `GiveKit`. It grants the
 **permission that gates a kit**, and the player redeems it themselves in game, whenever they next
 log in.
 **Kits already has exactly this model built in**, which is what makes it cheap: every kit carries a
 `RequiredPermission`, `GiveKit`'s own path checks it before handing anything over, and the in-game
 kit menu renders a kit the player lacks the permission for as locked rather than hiding it.
 `GetKitInfo` returns that permission under `["permission"]`, so the module can read which kits are
 gated and which are open to everyone.
 This is a better design than the one it replaces, and it is worth being explicit about how much it
 removes:
 - **The offline-grant problem disappears entirely.** `GiveKit` needed a connected `BasePlayer`, so an
  event firing at two in the morning rewarded only whoever happened to be online. An entitlement
  waits. **This closes the open question §3 carried** — no pending-grant queue, no second
  at-most-once store, none of it.
 - **It is the same machinery as R2, not a second mechanism.** A reward becomes a permission grant
  authored by the site and mirrored into Oxide — the thing phase 7 already builds. One permission
  authority, one drift story, one audit trail.
 - **`reversible: 'ledger'` becomes honest**, where a direct grant could only ever be `'none'`. See
  *"What phase 13 must declare honestly"* below.
 - **The player gets agency.** They redeem when they want it, where they want it, with Kits' own
  cooldown and use limits still applying — rather than having items appear in their inventory,
  possibly while they are somewhere it is a liability.
 **One design note the option source has to carry.** A kit with an **empty** `RequiredPermission` is
 open to everybody, so granting a permission for it rewards nobody with anything. The authoring form's
 kit dropdown must surface which kits are permission-gated and refuse — or at minimum warn loudly —
 on one that is not. That is a real refusal with a real reason, and exactly what R3's envelope is for.
 ## 3. Open questions
 **None.** Both questions this section carried were closed on 2026-09-15.
 *Clans in the base set while the Team provider reads first-party* was confirmed as the intended
 reading: complementary, not in conflict — the plugin is installed for alliances and clan chat, the
 provider is fed from the first-party system that actually publishes membership transitions (R5).
 *Offline reward grants* was dissolved rather than answered. **R16 changed the noun**: the reward
 action grants an entitlement instead of items, and an entitlement does not need the player to be
 online. The persisted pending-grant queue that question was weighing is not needed at all.
 ## 4. The test rig
 `D:\rust` on the org lead's workstation. It has been booted, it has a generated world
 (procedural, seed 1234, size 4000, save v287) and Oxide **2.0.7585** matched to its build, and its
 Oxide permission store already holds a `default` and an `admin` group with one admin user — which
 means R2's mechanism can be exercised on day one.
 Two traps recorded here because both cost time before they were understood:
 - **`D:\rust\start.bat` updated the wrong directory — fixed 2026-09-15.** It ran
  `steamcmd +force_install_dir c:\rustserver\ +app_update 258550` and then launched
  `D:\rust\RustDedicated.exe`. The server that boots had never been updated by its own script, which
  is why a second, never-booted install exists at `C:\rustserver` and why `D:\rust` is a wipe behind.
  Now reads `+force_install_dir d:\rust\`; the original is kept at `D:\rust\start.bat.bak`.
  `D:\rust\steamapps\appmanifest_258550.acf` was already present at the same buildid, so the first
  corrected run is a delta to the current wipe rather than a 5.9 GB re-download.
 - **`C:\oxide_files` is a 2025-04-23 Oxide and must not be copied anywhere.** Oxide ships a patched
  `Assembly-CSharp.dll`; that bundle's is 6,842,880 bytes against the live 9,780,224, so copying it
  over a real install is a hard downgrade. `D:\rust` is already correct and needs nothing from it.
 **Rust force-wipes on the first Thursday of the month and Oxide is rebuilt to match**, so "is the
 rig current" is a recurring question, not a one-time setup step. Every phase that touches the plugin
 re-checks it.
 ## 5. The phases
 **Twenty phases, roughly doubled from the first draft** — the contract audit in §7 is why, and the
 honest reading is that the first list was a game-bridge plan with a website module bolted on, where
 the kit treats the module as the bulk of the work.
 0–4 produce a working read-only multi-server Rust site that an operator can actually install. 6–7b are
 the permissions and remote-administration product. 9 is Teams. 10 is the notifications set, whose catalogue is **§10**. 12–13
 are events, whose catalogue is **§9**. 14 is the map. 18 is how any of it reaches somebody who is
 not us. The Android legs (5, 8, 11, 15) each trail the
 website surface they consume by one phase, per R10.
 Each phase ends with its findings written down, as every workstream here does.
 | # | Phase | Repos | Done when |
 |---|---|---|---|
 | 0 | **The rig.** Update to the current wipe (the script is fixed), confirm the Oxide build still matches, install the base set — Kits, Clans, PopupNotifications, ZoneManager (R6, R17) — prove a console grant reaches a plugin | docs | A current server boots with all four loaded, `oxide.grant` demonstrably gates something, and a test zone reports who is standing in it |
 | 1 | **Protocol 1, three skeletons, and every bundle seam at once.** Plugin: bounded drop-oldest queue, one writer thread, tagged reconnect epoch, dial-out. Sidecar: listener, SQLite, always-on token auth, version header, rpc correlation. Module: `id: rust`, `/rust` on all three tiers (R14), `schema.sql` **and `purge.sql`**, the vite aliases and shims, `checkExternals`, `checkImports`, the swagger fragment and its staleness check, explicit `onBoot`/`onShutdown`, `capabilities` | all 3 + docs | One hello line travels game -> sidecar -> module; killing the sidecar does not stall the game; all five guards green on an untouched skeleton |
 | 2 | **Packaging and release.** `release.yml`, the install manifest, the `sha256`, the host allowlist — and a real install into a running core from a manifest URL | Module-Rust + docs | An operator installs the empty module from Admin -> Modules and it reaches `started` |
 | 3 | **The read path.** First hook wave from [`HOOKS.md`](HOOKS.md); events and snapshots distinct at the wire; `wipe_id` **and server id** on every row (R8); all-time rollups (R12); every board re-emitted on connect | all 3 + docs | A restarted sidecar is fully populated within one connection, and a wipe does not erase a player's history |
 | 4 | **The first pages.** Server list as the landing page, `/rust/servers/:id` beneath it, killfeed, leaderboard; nav rows; the UI kit (`PublicLayout` `shell`, `PageHeader` props); `capabilities`; the `site.footer.status` slot (R13) | Module-Rust | The site renders the last thing each server said while every server is off |
 | 5 | **Android leg A** (R10). Capability-driven shell from `GET /api/v1/public/modules`, plus the phase-4 screens | Android-app | The app renders a Rust site it has never seen, and a UO site unchanged |
 | 6 | **Identity** (R1), and the `admin.users.detail` slot (R13) | 3 + docs | A player links an account in-game; an operator sees the Steam id inside core's own user page |
 | 7 | **Site-owned permissions** (R2). Groups and grants authored on the site; full set pushed on connect, deltas after; drift reported | all 3 + docs | A grant made on the website gates a third-party plugin in-game, and survives a wipe |
 | 7b | **Mod configuration from the site** (R18). **Recursive** walk of `oxide/config/` (never `oxide/data/`), generated form from the live values, raw-JSON advanced tier, explicit reload target, versioned read/write, auto-reload watched on `OnPluginLoaded`, **automatic rollback** over the whole file set, path-traversal guards, secret redaction, its own permission and an audit trail | all 3 + docs | An admin flips a ZoneManager setting from the website and it takes effect; a deliberately broken config rolls itself back and says why; a nested `<Mod>/x.json` is found and reloads the right plugin |
 | 8 | **Android leg B** (R10). Identity and permission surfaces | Android-app | A player links from the app |
 | 9 | **Teams from first-party clans** (R5). Membership event-driven, leadership read off `LocalClan` at snapshot; **`declareModuleSlot` × 3** for core's `team.notify` / `team.activity` / `team.forum` | Module-Rust + 2 | The clan page is ours, core's contributions land in places we named, and every slot empty still reads correctly |
 | 10 | **Notifications and engagement** (R7). Streams, triggers with `ceiling` and `subjectKey`, audiences, engagement seeds, announce leg, post hook — **the catalogue is §10**, including the in-game-popup question | Module-Rust + docs | The offline raid alert reaches the player whose base it was, and nobody else |
 | 11 | **Android leg C** (R10). Inbox and notification preferences for Rust triggers | Android-app | A Rust notification arrives on a phone and can be switched off there |
 | 12 | **Events: budgets, option sources and the leases** (§9). [kit][kit] ch. 5's own ordering — leases before actions — and every key verified live before it is advertised | Module-Rust + 2 | A leased value is observed changing in the running game and restored, per key; `rust.group.membership` expires without core asking |
 | 13 | **Events: the actions** (§9, R3, R16). `rust.kit.entitle` first, then `rust.prefab.place` and `rust.announce`; `reversible: 'ledger'`; the kit option source flags kits with no permission gate | all 3 + docs | A reward granted at 03:00 is waiting in the kit menu when the player next logs in, and a revert withdraws it |
 | 14 | **The live map** (R9). The map image over the bridge — request/reply, two-stage, one in flight, its own derivation version, no import on boot — plus the live layers and a per-layer public/players/admin switch | all 3 + docs | The map renders for the current wipe, and a player layer is invisible until an operator deliberately opens it |
 | 15 | **Android leg D** (R10). Map and events | Android-app | The map renders on a phone with the same layer gates |
 | 16 | **Discord slash commands** (R11). A small read-only set, every refusal deferred ephemeral | Module-Rust + docs | A refusal does not go public in the channel |
 | 17 | **Optional mod integrations** (R15). **BetterChat** first — leaderboard titles through `API_RegisterThirdPartyTitle`, a pull with no drift — then the uMod **Clans** adapter (alliances and clan chat, beside the provider rather than under it, R5), then others as they prove useful | Rust-Plugins + Module-Rust + docs | A server missing every optional mod still runs the module, Teams included |
 | 18 | **The installer** (R4). `--game servuo|rust`, the bundle payload as a variant, an Oxide prerequisite check in `doctor`, the protocol pairing refusal carried over | installer + docs | An operator sets a Rust server up with the released binary and nothing hand-copied |
 | 19 | **Docs, kit feedback, cutover.** `docs/`; **`.profile`** (three repos were added); **`runicgateway.com`** (a second game is a headline change); and the Integration-kit question R2 raised | docs + Integration-kit + .profile + runicgateway.com | `docs/` describes what shipped, the front door names the new repos, and R2's missing chapter is answered either way |
 ### Why the lease comes before the reward action
 The stated priority is Kits rewards, and this plan still schedules a lease first (12 before 13). [kit][kit] ch. 5 is
 explicit about it and the reasoning survives restating: a lease is *a value that already existed,
 changed for a while, and put back*, so reading it first gives you the baseline for nothing. An action
 makes something that did not exist. The lease proves the whole command path — correlation, the
 idempotency key, `budgetMs` against the client timeout, the deadline the game enforces on its own —
 before anything hands out loot. It is a cheaper place to find all four of chapter 5's invisible
 failures.
 Reversible on request.
 ### What phase 13 must declare honestly
 > **Rewritten 2026-09-15 by R16.** This section previously argued that a kit reward could only be
 > `reversible: 'none'`, because there is no honest way to un-grant loot a player has already spent.
 > That was correct *about a direct grant* and R16 stopped doing direct grants. The reasoning is kept
 > below in its corrected form because the shape of the mistake is the reusable part: **the action was
 > declared around the wrong noun.** What the event makes is not loot; it is an entitlement.
 **The reward action grants an entitlement, and an entitlement is reversible.** `revert` revokes the
 permission, removing one that is not there is a success, and it is idempotent by construction — so
 **`reversible: 'ledger'` is the honest declaration**, and core's ledger sweep does real work on every
 terminal path.
 One consequence to state rather than discover: **a player who redeemed before the revert keeps the
 items.** That is correct and not a hole. The ledgered resource is the *grant*, and reverting it
 withdraws the entitlement rather than the consumption — the same way cancelling a coupon does not
 un-eat the meal. An operator reading the run console should see that distinction in the wording.
 **`cost()` counts permission grants, and unlike a kit count it is exactly knowable before dispatch.**
 That removes the whole class of problem chapter 5 §4 warns about: there is no "declare the maximum
 because you cannot know until the answer comes back". One recipient is one grant. Core prices `cost`
 before dispatch and never reconciles it, so being able to count precisely is worth more than it
 sounds.
 **And the idempotency key largely stops mattering here**, which is the tidiest part of R16. Chapter 5
 §2 draws the line itself: *"A key is for a write whose repetition would be a second EFFECT —
 creating, granting, announcing. A write that SETS a value to X is idempotent by its own nature."* A
 permission grant is a set. Pass the key through anyway — it costs nothing and it is what the
 contract expects — but the failure mode it exists to prevent, a socket hiccup producing a second set
 of everything, no longer has a way to happen.
 The monthly wipe is still the case `revert`'s tolerance rule was written for: if a wipe or a rebuilt
 host clears Oxide's permission store, every ledgered grant is invalidated at once and **"gone, and
 that is fine" is a success**. Note this is also where R2 pays for itself twice — the site re-pushes
 its whole permission set on the next connect, so an entitlement an event granted comes *back* rather
 than being quietly lost.
 ## 6. Risks worth naming now
 - **Hooks bind by name and arity, by reflection, with no compile-time check.** A misspelled hook is
  never called, silently, with no warning at load — the single most common way a Rust plugin does
  nothing. The plugin must log which of its expected hooks have fired at least once, so a hook
  Facepunch renamed on a wipe is visible rather than mysterious. See [`README.md`](README.md) §2.
 - **A convar that applies cleanly and does nothing.** Most game config is read once at boot and
  cached; applying it later succeeds, reads back correctly, and changes nothing. Every lease key gets
  verified live — apply, observe in the running game, restore — before it is advertised. The UO
  module surveyed 156 config reads and found roughly eight that were live.
 - **The wipe cadence is the schedule.** A monthly force wipe moves the hook list, rebuilds Oxide, and
  invalidates every ledgered resource. Phases that end near one should expect to re-verify rather
  than assume.
 - **`start.bat`'s RCON password is `letmein` in plaintext with `rcon.web 1`.** Acceptable on a
  loopback dev rig, and it must never be the shape anything published copies.
 ## 7. Contract coverage audit
 Added 2026-09-15 after re-reading the whole kit rather than only chapters 3-5. **The first draft of
 §5 was built from the game-facing chapters and under-planned the website module by a wide margin** —
 the template makes eight of the ten non-event registrations and the plan covered three. Every element
 is listed with the phase it now lands in; the column worth reading is *"was it in the first draft"*,
 because that is the shape of the mistake.
 ### The server handshake — ten registrations plus two hooks (ch. 2)
 | Call | In the first draft | Phase |
 |---|---|---|
 | `registerRoutes` | yes | 4 |
 | `registerTeamProvider` | yes | 9 |
 | `registerEventBudgets` / `OptionSources` / `Leases` / `Actions` | yes | 12-13 |
 | `onBoot` / `onShutdown` | implicit only | 1 |
 | `registerExtension` | **no** | 4 (`site.footer.status`), 6 (`admin.users.detail`) |
 | `registerNotificationStreams` | **no** | 10 |
 | `registerEventTriggers` | **no** | 10 |
 | `registerAudiences` | **no** | 10 |
 | `registerEngagementSeeds` | **no** | 10 |
 | `registerAnnounceLeg` | **no** | 10 |
 | `registerPostHook` | **no** | 10 |
 | `registerSlashCommands` | **no** | 16 |
 Triggers, audiences and seeds are one phase because they are a **matched set** in
 `template/server/index.js`, not three independent gaps — see R7.
 ### The bundle's own parts
 | Part | In the first draft | Phase |
 |---|---|---|
 | `module.json` `id` / `coreApi` / `capabilities` | yes | 1, 4 |
 | `mounts` and prefix choice | **no** | 1 (R14) |
 | `schema.sql` | yes | 1, 3 |
 | `purge.sql` | **no** | 1 |
 | `swagger-fragment.json` + generator + `check:swagger` | **no** | 1 |
 | `vite.config.js` aliases / shims / `checkExternals` | **no** | 1 |
 | `checkImports.js` | **no** | 1 |
 | `release.yml`, install manifest, `sha256`, host allowlist | **no** | **2** — there was no packaging phase at all |
 Phase 1 carries most of these on purpose. [kit][kit] ch. 1's whole argument is to get every seam
 working at once with almost nothing in them, so that afterwards you break exactly one at a time.
 ### The client half
 | Part | In the first draft | Phase |
 |---|---|---|
 | `registry.registerRoutes` / `registerNav` | yes | 4 |
 | `declareModuleSlot` | **no** | 9 — the kit: *"you will need it the moment your game has anything like a guild"* |
 | `registerFeatureProvider` | **no** | 4 |
 | UI kit discipline (`PublicLayout` `shell`, `PageHeader` props) | **no** | 4 |
 ### Beyond the module
 | Item | In the first draft | Phase |
 |---|---|---|
 | Sidecar rpc correlation | implicit | 1, stated |
 | Asset bridge (ch. 3 §2b) | **no** | 14 — **map image only** (R9) |
 | `.profile` landing page | **no** | 19 |
 | `runicgateway.com` | **no** | 19 |
 | Android app | **no** | 5, 8, 11, 15 (R10) |
 | `docs/` | yes | every phase, plus 19 |
 **What the audit cost the schedule: twelve phases.** That is the honest number, and it is worth
 recording because the under-planning had one cause — reading the chapters that describe the game
 bridge and treating the module as the thin part, when the kit says in its first paragraph that the
 website module is most of the work.
 ## 8. Questions the audit raised — all answered
 Every question §7 produced was put to the org lead on 2026-09-15 and answered the same day. They are
 recorded as R7–R14 in §2 rather than repeated here:
 | Question | Answer | Decision |
 |---|---|---|
 | Notifications and engagement in v1? | the full matched set | R7 |
 | How many servers does the UI support? | multi-server from the start | R8 |
 | The asset bridge? | **only** the live map — not item icons, not skins | R9 |
 | Android in this workstream? | full app, capability-driven, trailing by one phase | R10 |
 | Discord slash commands? | a small read-only set | R11 |
 | What survives a wipe? | per-wipe detail plus all-time rollups | R12 |
 | Extension slots? | `admin.users.detail` **and** `site.footer.status` | R13 |
 | Which mount prefixes? | `/rust` on all three tiers | R14 |
 §3 is empty; both were closed on the same day.
 ## 9. The event catalogue
 Added 2026-09-15. **Phases 12–13 described the event *mechanism* and never the *catalogue*** — one
 budget and one lease as a proof of life, which is a skeleton rather than a product. This section is
 what the module actually declares.
 [`EVENTS.md`](../../website/EVENTS.md) **§H is a Rust/Oxide compatibility section that already
 sketched this**, and it should have been read before §5 was written. What follows takes its ids and
 its reasoning as the starting point rather than inventing a parallel set.
 > **§H's thesis, and it is the one to design around:** *"The lease is the primitive that travels, not
 > the spawn. Double gather rate for the weekend is the canonical Rust community event, and it is
 > exactly lease-with-expiry. Spawning creatures at a landmark is UO-shaped; holding a value for four
 > hours is every game."* It also rates Rust the **easier** case than UO, because Oxide's convars are
 > live by default where ServUO's are mostly cached at boot.
 ### Budgets — what core counts and bounds
 | Dimension | Counts |
 |---|---|
 | `rust.prefabs` | objects placed into the world by a run |
 | `rust.zone.minutes` | zone time held — real since R17 |
 | `rust.grants` | entitlements granted (R16) |
 | `rust.announcements` | in-game broadcasts |
 **Caps are per run, and R8 makes that load-bearing.** §H: `run.scope` is part of a run's unique key,
 so one definition fanning out to six servers is **six separate budgets, not one shared pool**. An
 operator setting a cap of 30 prefabs is setting it per server. Say so on the field.
 ### Option sources — what fills a dropdown
 | Source | Filled from |
 |---|---|
 | `rust.options.kits` | Kits `GetKitNames` / `GetAllKits`, **flagged by whether `RequiredPermission` is set** (R16) |
 | `rust.options.groups` | Oxide permission groups (§H names this one) |
 | `rust.options.permissions` | registered permissions |
 | `rust.options.prefabs` | a plugin-declared constructible allowlist — the analogue of UO's spawn atlas |
 | `rust.options.monuments` | monument names, shared with the map work (R9) |
 | `rust.options.zones` | ZoneManager `GetZoneIDs` / `GetZoneName` (R17) |
 Every one resolves from live data and returns `[]` on failure rather than defending with a hardcoded
 list that will be wrong. A source that refuses degrades its field to free text with a warning and
 never blocks the form.
 ### Leases — values borrowed with a deadline
 The heart of it, and the thing to build first.
 | Lease | Value |
 |---|---|
 | `rust.rate.gather` | gather rate multiplier |
 | `rust.rate.craft` | craft speed |
 | `rust.rate.smelt` | smelting speed |
 | `rust.rate.decay` | decay scale |
 | `rust.time.night` | night length |
 | `rust.population.<kind>` | spawn population multipliers |
 | `rust.group.membership` | **a time-limited permission group — weekend VIP** |
 **`rust.group.membership` is the one §H names that R16 did not, and the pair is the whole design.**
 R16 settled that a *permanent* earned entitlement is an **action** with `reversible: 'ledger'` — grant
 the kit's permission, revert revokes it. §H settles that a *time-limited* group is genuinely
 **`core.lease`** — held with a deadline the game enforces on its own, restored when it expires
 without core having to come back. Same underlying permission mirror (R2), two different shapes,
 and choosing the wrong one is the mistake: a weekend VIP implemented as a grant is a VIP who stays
 one for ever if the website goes away.
 **Every key gets verified live before it is advertised** — apply, observe in the running game,
 restore, per key. §H's claim that Rust convars are live by default is an argument for *expecting*
 them to work, never a substitute for checking. A value the server reads once at boot applies
 cleanly, reads back cleanly, and does nothing at all, and neither core nor review can catch it.
 ### Actions — verbs a run performs
 | Action | `risk` | `reversible` | Notes |
 |---|---|---|---|
 | `rust.kit.entitle` | `change` | `ledger` | R16 — grants the kit's `RequiredPermission`; revert revokes |
 | `rust.prefab.place` | `change` | `ledger` | §H's verb; revert kills the entity, and needs the persisted ownership registry ch. 4 describes |
 | `rust.announce` | `notify` | `none` | via PopupNotifications (R6) — global or targeted |
 | `rust.zone.open` | `change` | `ledger` | §H's other verb. **Base, not optional, since R17** — `CreateOrUpdateTemporaryZone` takes a `Plugin owner` and `EraseTemporaryZone` is scoped to it, so the undo is real |
 **Rewards are not a contract member.** `EVENTS.md` deleted a `registerEventRewards` registry because
 it carried four Ultima Online nouns inside a core signature. A reward here is an ordinary action —
 which is exactly why R16 could change what it grants without touching anything of core's.
 ## 10. The engagement catalogue — what Rust can expose
 Added 2026-09-15, answering "check the default alerts Rust can expose". R7 settled that the set
 ships; this is what goes in it.
 **The ceiling lattice is containment, not size** — `self`, `owner`, `subscribers`, `staff`,
 `members`, `authenticated`, `everyone`, and the flat reading is the trap. `staff` is **not** a
 superset of `owner`: for a cheat-detection event, "one person" is *the player it was detected on*.
 Every ceiling below is chosen against that, not against a ladder.
 | Trigger | Source | `ceiling` | `subjectKey` |
 |---|---|---|---|
 | `rust.wipe.started` | `OnNewSave` | `everyone` | server |
 | `rust.server.online` / `.offline` | link state transition | `everyone` | server |
 | `rust.leaderboard.topped` | our own rollup (R12) | `everyone` | server |
 | `rust.base.destroyed` | `OnEntityDeath` on owned building blocks | **`owner`** | player |
 | `rust.kit.entitled` | R16's own grant | **`self`** | user |
 | `rust.player.linked` | R1's link flow | **`self`** | user |
 | `rust.clan.member.added` / `.left` / `.kicked` | first-party clan hooks (R5) | `members` | clan |
 | `rust.clan.disbanded` | `OnClanDisbanded` | `members` | clan |
 | `rust.player.reported` | `OnPlayerReported` | **`staff`** | player |
 | `rust.login.denied` | `CanUserLogin` | **`staff`** | player |
 | `rust.player.banned` / `.unbanned` | `OnUserBanned` / `OnUserUnbanned` | **`staff`** | player |
 **`rust.base.destroyed` is the one that matters most and the one most likely to be got wrong.** The
 offline raid alert is the single most-wanted notification in Rust, and its ceiling is `owner` — the
 player whose base it was. Ceilinged `staff` it would be useless to the person who needs it, and
 ceilinged `everyone` it would broadcast base locations to the server. This is exactly the case the
 lattice exists for.
 **Three hooks carry data that must never widen.** `CanUserLogin` and `OnUserApproved` carry **IP
 addresses**; `OnPlayerReported` carries player reports. [`README.md`](README.md) §5 already flags
 these as admin-channel-only on the live feed, and the same judgement binds their triggers.
 ### Audiences
 | Audience | Resolves to | `ceiling` |
 |---|---|---|
 | `rust.clan.members` | a clan's linked members | `members` |
 | `rust.server.players` | linked accounts seen on a server this wipe | `authenticated` |
 | `rust.wipe.participants` | everyone who played the current wipe | `authenticated` |
 A resolver returns **user ids and nothing else** — never a template, a channel or an address — and
 one that fails resolves to **nobody**, never to everybody and never to its last good answer. Its
 params are constant, filled in when an operator saves the rule, so "the clan this event was about"
 is not expressible; an event that needs that carries its own recipients.
 ### Seeds, and one thing to decide when building them
 Bodies re-ensure every boot under a seed version; **rule groups are offered once per group key**, so
 a rule appended to an existing group reaches fresh installs only. Wipe announcements, raid alerts and
 clan transitions each take their own group key for that reason.
 **One design note, flagged rather than decided.** `PopupNotifications` gives the module an *in-game*
 alert surface, which is not one of core's channels — core resolves ids to email, in-app and push. So
 an in-game popup is the module publishing to its own surface off its own trigger, not a fourth
 channel core learns about. Worth settling deliberately at phase 10: a raid alert that reaches a
 player's phone *and* pops on their screen next login is two mechanisms, and only one of them is
 core's.
