+### 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.

+reading: complementary, not in conflict — the plugin is installed for alliances and clan chat, the

-**Offline reward grants.** `GiveKit` requires a connected `BasePlayer` (R6). Whether the reward phase
-accepts online-only or builds a persisted pending-grant queue is a real decision with real cost, and

-`D:\rust\oxide\plugins\` is **empty**, so the whole base set is a fresh install in phase 0.
+*Offline reward grants* was dissolved rather than answered. **R16 changed the noun**: the reward

 ### What phase 13 must declare honestly
 
-**A kit grant cannot be `reversible: 'ledger'`.** That value is a promise that core may come back and
-have the thing undone, on every terminal path including an abort — and there is no honest way to
-un-grant loot a player has already spent. The correct declaration is `reversible: 'none'`, and saying
-so is the point: a capability that claims a reversal it cannot perform is the "capability that lies"

+> **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.
 
-`cost()` must count the kits actually granted, derived from the params, every time. Core prices
-`cost` before dispatch and never reconciles it against what came back — it cannot, it does not know
-what a kit is — so an action that reports one while granting twelve turns an operator's cap of 30
-into a cap of 360 with nothing anywhere going red.
+**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.
 
-And the monthly wipe is the case `revert`'s tolerance rule was written for: every ledgered resource
-is invalidated at once, and **"gone, and that is fine" is a success**, not a failure.
+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.
