-# Horizon governance
-
-> Adopted 2026-11-09 by the founder as his last decision as head of the project. It takes effect when he
-> announces that he is stepping down. From then on only the council changes it, by a 2/3 poll (section 15).
-
-Horizon has no boss. A **council of equals** decides by polls. **Theme groups** do the work in their areas, each
-with a **lead**. The **Horizon Team** reviews and merges code. **Moderators** keep the Discord server and the
-official server safe. Every role of trust is earned with work the project can measure, and it ends when that work
-stops.

-## 1. Principles
-
-- **Equals.** Every council member has one vote. Nobody, the founder included, stands above the others.
-- **The founder.** Ludovic keeps the title of **Founder**: his role stays at the top of the member list and he is
-  credited as Horizon's founder everywhere. The title is symbolic. It carries no extra vote or power: on the council
-  he counts exactly like every other member.
-- **Evidence, not popularity.** You get a role by doing the work first. Kira measures that work: merged pull
-  requests, reviews, triage, support answers and days active. A vote then confirms it.
-- **Small, clear powers.** Each role can do a short, written list of things. Anything else goes to the council.
-- **Roles are on loan.** Every role has a 30-day probation and an inactivity rule. Stepping down for inactivity is
-  not a sanction, and you can come back.
-- **Public by default.** Polls, results and rules are public. Only matters about a person stay private, and even then
-  the result is published.
-- **18+ for roles of trust** (section 9).
-- **Mojang's and Microsoft's rules come first.** They are never put to a vote (section 14).
-
-## 2. The levels at a glance
-
-From the most open level to the most trusted. A person can hold several levels at once: a group lead can also be on
-the Horizon Team, for example.
-
-| Level | What it can do | How you get in | How you leave | 18+ |
-| --- | --- | --- | --- | --- |
-| **Member** | Play, chat, report bugs, suggest ideas, open issues and pull requests, pick group roles | Join the Discord server or the GitHub repo | Leave, or get banned | No |
-| **Contributor** (⛏️ Iron, 🥇 Gold, 💎 Diamond, 🟪 Netherite ranks) | Write in #contributors; `/claim` issues; nominate people for group lead (if active in that group) | One merged pull request in a public horizon-rust repo, linked with `/link-github` and `/verify-github`. Ranks come from merged pull requests: 10, 40, 100 and 200 | Contributor status and ranks stay | No |
-| **Group member** | Read and write in the group's channel; get the group's pings; take part in the group's advisory poll on its lead | Pick the group's role in Channels & Roles, or with `/groups` | Remove the role | No |
-| **🤝 Support** | Answer and close posts in #horizon-support | `/apply`; vote of the mods and the Team (as today) | Resign, 30 days inactive, or removed by the Chief of Mods or the council | No |
-| **🛡️ Moderator** | Time out, delete messages, manage threads, quarantine. No bans | `/apply`, then the selection filter; mods' vote; the council may object within 24 h | Resign, 30 days inactive, suspended by the Chief of Mods, removed by a council poll (simple majority) | **Yes** |
-| **🛡️ Chief of Mods** | A moderator's powers, plus bans; leads the mods; suspends a mod at once pending the council | Council poll (simple majority), from the mods with at least 30 days | Resign, 30 days inactive, council poll (simple majority) | **Yes** |
-| **🧭 Group lead** | Decides inside the group's topic (section 6); manages the group's channel; triage on the group's GitHub issues | Nomination, the filter, a 24 h public discussion with an advisory group poll, then a council poll (simple majority); 30 days probation | Resign, 30 days inactive (automatic), council poll (simple majority); confirmed again every 6 months | **Yes** |
-| **🌌 Horizon Team** | Review and merge pull requests (GitHub `horizon-team`, write access); `/nightly` and triage commands (trusted reviewers); #horizon-team | Nomination, the filter, a 24 h public discussion, then a council poll (2/3); 30 days probation | Resign, 60 days without a merge or review (automatic), council poll (2/3, without the person) | **Yes** |
-| **🏛️ Council** | Decides everything else by poll (section 4); bans; emergency actions by any 2 members | Nominated by a council member, the filter, a 24 h public discussion, then a council poll (2/3); 30 days probation | Resign, inactivity (section 5.5), council poll (2/3, without the person) | **Yes** |
-
-**The account holder** isn't a level. The founder (Ludovic) still holds the project's accounts (GitHub organisation
-owner, Discord server owner, the Microsoft app approved by Mojang, the domains, Railway, money). He carries out the
-council's decisions on them and hands them over step by step (section 11). As a council member he has one vote,
-like everyone else.
-
-## 3. Each level in detail
-
-### Member
-
-Anyone in the Discord server or on GitHub. Members follow the server rules and Horizon's
-[contributing guide](CONTRIBUTING.md). They can propose anything: an idea in #horizon-ideas, a bug in #horizon-bugs,
-an issue or a pull request on GitHub, or a request for a council poll (any council member can pick it up).
-
-### Contributor
-
-- **Discord:** the 🛠️ Contributor role writes in #contributors and in the threads of #polls-and-decisions. A rank
-  role (⛏️ Iron at 10 merged pull requests, 🥇 Gold at 40, 💎 Diamond at 100, 🟪 Netherite at 200, counted over every
-  public horizon-rust repo) shows how much has been merged. Ranks only go up.
-- **GitHub:** no repository role. Anyone can `/claim` and `/unclaim` their own issues.
-- **Alone:** their own work.
-
-### Group member
-
-Each theme group (section 6) has a role that anyone can pick and drop. It opens the group's channel and receives the
-group's pings. Picking a role grants no power. A group member counts as **active in the group** when Kira has seen at
-least one counted action in the group's area (section 5.1) in the last 60 days. Only active group members can
-nominate a lead or vote in the group's advisory poll.
-
-### 🤝 Support
-
-Unchanged: Support members help players in #horizon-support. They answer every post there and mark posts solved.
-The role carries no permission, so it has no age rule. They join through `/apply`, and the mods and the Team vote.
-
-### 🛡️ Moderators and the Chief of Mods
-
-- **Discord:** time out members, delete messages, manage threads and nicknames, read the audit log, quarantine
-  through Kira, and see the staff channels. **Moderators don't ban.** Bans are done by council members and the Chief of
-  Mods. Kira's automatic actions (the honeypot, clear scams, illegal images) stay as they are.
-- **Official server:** server operators (ops) are moderators in game. They need the 18+ rule and are confirmed the
-  same way (section 6, Server and SMP).
-- **Alone:** a timeout, a deleted message, a quarantine, with a reason in the mod case.
-- **The Chief of Mods** is the first contact for moderation questions. They organise the mods, can ban, and can take a
-  moderator's role away at once when there is a problem. The council confirms or reverses that within 72 hours.
-
-### 🧭 Group leads
-
-Section 6 says what a lead decides alone and what goes to the council.
-
-- **Discord:** in their group's channel only, delete messages, manage and pin threads, and ping the group role. The
-  🧭 lead role carries no server-wide permission.
-- **GitHub:** triage on the issues and pull requests that carry their group's label (`/label`, `/unlabel`, `/close`,
-  `/reopen`, `/unclaim`), from a list of group leads that grants no repository role. Leads merge only if they are on
-  the Horizon Team too.
-
-### 🌌 Horizon Team
-
-The Horizon Team **merges pull requests**. Its rules are in [the release flow](docs/release-flow.md): read the whole
-diff, never merge your own pull request, and use `needs-proof` for anything risky.
-
-- **GitHub:** member of the `horizon-team` team (write access to the Horizon repos), on the trusted reviewers list
-  (`/nightly` and triage commands).
-- **Discord:** the 🌌 Horizon Team role, #horizon-team, and writing in #contributors and the read-only channels.
-  Moderation permissions belong to the moderators and the council: a Team member moderates only if they also hold
-  one of those roles.
-- **During the 30-day probation:** they merge only ordinary pull requests. They don't merge `needs-proof` pull
-  requests, don't approve files that CODEOWNERS guards, and don't use `/nightly`.
-
-### 🏛️ Council
-
-- **Discord:** the 🏛️ Council role: the moderators' permissions plus ban and mention @everyone; #council (private);
-  starting polls in #polls-and-decisions.
-- **GitHub:** the `council` team. Over time it takes over the founder's CODEOWNERS review and his owner powers in the
-  release tools (section 11).
-- **Alone (any one member):** start a poll; pick up a member's request for a poll; do anything their other roles
-  allow.
-- **Any two members together:** an emergency action (section 4.6).
-- **Everything else** is decided by poll.
-
-## 4. The council and its polls
-
-### 4.1 Founding council
-
-kacpherek, levzzz5154, rdbtCVS, Online5277, dezer-x and Ludovic: six members, one vote each. The founding members
-don't go through the filter or a probation. They do make the 18+ declaration (section 9). The council has at most
-**9** members. It adds a seat only when a 2/3 poll says it needs one.
-
-### 4.2 How a poll works
-
-| Rule | Value |
-| --- | --- |
-| Who starts one | Any council member, with `/poll` (Kira). Anyone else asks a council member to start it |
-| Where | #polls-and-decisions, in public. Polls about a person (removal, appeals, the age rule) run in #council, and only their result is public |
-| How long | 24 hours. It closes early only if every council member has voted |
-| Ballot | Yes, No or Abstain. You can change it until the poll closes |
-| Quorum | At least half of the council votes (Abstain counts). With 6 members, 3 votes |
-| Simple majority | More Yes than No |
-| Two-thirds | Yes is at least 2/3 of the Yes and No votes, **and at least 3 Yes votes** |
-| Tie | Nothing changes |
-| No quorum | Nothing changes. Kira reminds the members who haven't voted 12 hours and 2 hours before the end |
-| About yourself | You don't vote, and you don't count in the council's size for that poll |
-| Asking again | A poll that failed can't be asked again for 7 days, unless two members agree that new facts justify it |
-
-### 4.3 Which threshold applies
-
-| Simple majority | Two-thirds |
-| --- | --- |
-| Day-to-day project decisions: direction, priorities, settling disputes between groups, a public statement | Adding council members and Horizon Team members |
-| Group leads and co-leads: appointing, removing, confirming every 6 months | Removing a council member or a Team member (without the person concerned) |
-| Moderators, the Chief of Mods, Support: confirming, removing | Rules: this document, the server rules, the contributing policy, the licence |
-| Ending a probation early | Money (section 12) |
-| Confirming an emergency action | Account handover steps (section 11) |
-| Second-level moderation appeals | Waiving part of the selection filter (section 5.4) |
-| Bringing back someone who stepped down for inactivity, within 6 months | Changing the council's size |
-
-**When in doubt, two-thirds.** Any council member can say a poll needs 2/3, and Kira then counts it at 2/3.
-
-### 4.4 Discussion
-
-Polls that add someone to the council, the Team or a lead post start with a **24-hour public discussion** (section
-5.3). Other polls are discussed in their own thread while they run. A member who wants more time votes No and says
-why. A failed poll can come back after 7 days.
-
-### 4.5 Conflicts of interest
-
-A member doesn't vote on a poll about themselves: their own role, their own removal, an appeal of their own
-moderation action, or money paid to them. They say so in the poll's thread and Kira leaves them out of the count.
-
-### 4.6 Emergencies
-
-For **security** (a leaked secret, a malicious pull request or mod, a hijacked account), **Mojang or Microsoft** (a
-request from them, a risk to the approved sign-in) or **legal** matters (a takedown, the law), **any two council
-members act at once**. They may:
-
-- pause releases and the Nightly;
-- take a mod down from the registry;
-- remove someone's roles or access for now;
-- lock or hide channels and content;
-- ask the account holder to rotate a secret or a key.
-
-They record it with `/emergency` in Kira, and both of them confirm it there. Kira opens a council poll at once
-(simple majority) to confirm it. If the poll doesn't pass, the action is undone where it can be. An emergency never
-adds members, changes rules or spends money.
-
-### 4.7 Removing a council member
-
-A 2/3 poll of the other members, in #council. The person concerned doesn't vote and doesn't count in the quorum.
-Only the result is published, never the reasons. Other ways to leave: resigning, inactivity (section 5.5), or a
-false age declaration (section 9).
-
-### 4.8 When the council drops below a quorum
-
-- **Fewer than 5 members:** Kira opens nominations for the council at once. The council fills seats within 30 days.
-- **Fewer than 3 members, or fewer than 3 who voted in the last 30 days:** an **interim council** forms. It counts the
-  remaining council members, the Horizon Team and the group leads past probation. Its only task is adding council
-  members, by its own 2/3 poll with a quorum of half. Any two of its members can take emergency actions. All other
-  decisions wait. The Team keeps merging and the leads keep leading.
-- **Nobody left:** the Team and the group leads form the interim council in the same way.
-
-## 5. The selection filter
-
-Nobody becomes a lead, a Team member or a council member just because they are well liked or talk a lot. Kira
-measures the work, and only people above a floor can be nominated. The council then decides among them.
-
-### 5.1 What Kira measures
-
-| Signal | What counts | Source |
-| --- | --- | --- |
-| **Merged pull requests** | Pull requests merged in a public horizon-rust repo. For Modding, also in the mod API's fork (arismoko/horizon). Counted overall, and per group by label or by files touched | GitHub search, as the ranks are counted today |
-| **Reviews** | Others' pull requests you reviewed: approved, asked for changes, or left a review with comments. One per pull request | GitHub search `reviewed-by:` and Kira's GitHub webhook |
-| **Triage** | Triage commands run (`/label`, `/close`, duplicates), issues labelled or closed, bug posts routed on Discord | The triage workflow's comments and Kira's webhook |
-| **Support answers** | #horizon-support posts you answered that ended solved | Kira's support feature |
-| **Active days** | Distinct days with any of the above, or with messages in #contributors or a group's channel. Chat elsewhere doesn't count | Kira |
-| **Tenure** | Days since your first counted contribution (since you joined the server, for moderators) | GitHub, Discord |
-| **Clean record** | No timeout, quarantine or ban in the last 90 days | Kira's mod cases |
-| **Verified GitHub** | `/verify-github` done | Kira |
-| **18+ declaration** | Made (section 9) | Kira |
-
-Kira turns these into an **evidence card**: the person's numbers, overall and in the group's area, for the last 60
-days and in total. Anyone can see their own card with `/evidence`. A nomination shows the card publicly.
-
-### 5.2 The floors
-
-A nomination is refused below these floors.
-
-| Role | Floor |
-| --- | --- |
-| **Group lead** | Verified GitHub; tenure of 30 days or more; **in the group's area: 8 or more merged pull requests, or 20 or more reviews** (Translations: 5 or more merged translation pull requests; Server and SMP: 8 pull requests, or 30 days as an official server operator with activity); 15 or more active days in the last 60; clean record; 18+ |
-| **Moderator** | In the server for 30 days or more; Kira level 10 or more; 15 or more active days in the last 60; clean record; 18+ |
-| **Chief of Mods** | Moderator for 30 days or more, past probation; 18+ |
-| **Horizon Team** | 🥇 Gold rank (40 merged pull requests); 20 or more reviews of others' pull requests; tenure of 30 days or more; 20 or more active days in the last 60; clean record; verified GitHub; 18+ |
-| **Council** | Horizon Team member, group lead or Chief of Mods for 60 days or more, past probation; 20 or more active days in the last 60; clean record; 18+ |
-
-The numbers are checked again once a year (section 15). They should stay reachable for people who really work on
-Horizon and out of reach for people who don't.
-
-### 5.3 The path to a role
-
-1. **Nomination.** Run `/nominate member: role: [group:]` in Kira.
-   - A **group lead** can be nominated by an active member of that group or by a council member. A self-nomination
-     needs a second from another active group member or a council member.
-   - A **Team member** can be nominated by a council or Team member. Someone can also nominate themselves with
-     `/apply`, if a council or Team member sponsors them.
-   - A **council member** can only be nominated by a council member.
-   - **Moderators** apply with `/apply`.
-2. **The filter.** Kira checks the floor and the 18+ declaration. Below the floor, Kira refuses and says which line
-   is short.
-3. **Public discussion, 24 hours.** Kira posts the nomination and the evidence card in a thread of
-   #polls-and-decisions. Contributors and the council can comment. For a lead, Kira also runs an **advisory poll** in
-   the group's channel for the same 24 hours. Only active group members vote in it, and the council sees the result.
-4. **Council poll, 24 hours.** Simple majority for a lead, 2/3 for the Team and the council. For moderators, the mods'
-   vote replaces this step, and any two council members can object within 24 hours; the council then decides by poll.
-5. **Probation, 30 days.** The role is held in full, except for the Team limits in section 3. At day 25, Kira asks the
-   council in #council whether anything is wrong. Probation ends by itself at day 30, unless a council poll (simple
-   majority) ended it earlier.
-
-### 5.4 Exceptions
-
-Some valuable people don't show up in the numbers, such as a designer for the website. The council can **waive the
-tenure or the area floors** by a 2/3 poll that says why. The age rule and the clean record are never waived.
-
-### 5.5 Inactivity
-
-Kira checks every day. It warns the person in a DM and in #council, then posts the step-down in
-#polls-and-decisions with neutral wording ("stepped down: inactive"), and removes the Discord role. The account
-holder or an org owner removes GitHub access when the Team role ends.
-
-| Role | What counts as activity | Warning | Steps down |
-| --- | --- | --- | --- |
-| Group lead | A counted action in the group's area, or messages in the group's channel | Day 21 | Day 30 |
-| Horizon Team | A merge or a review | Day 45 | Day 60 |
-| Moderator, Chief of Mods | A moderation action, or messages in the staff channels | Day 21 | Day 30 |
-| Support | An answer in #horizon-support | Day 21 | Day 30 |
-| Council | A vote in a poll. At 30 days with no vote, while at least 2 polls were held | Day 23 | Day 30, or 45 days with no counted activity at all |
-
-- **Away.** Anyone can announce an absence with `/away` for up to 45 days, once every 6 months. Away days don't
-  count. A lead names someone from the group to cover for them.
-- **Coming back.** Within 6 months: a simple-majority poll, with no new probation. After 6 months: the normal path.
-
-### 5.6 Terms
-
-- **Group leads** are confirmed every 6 months by a simple-majority poll. If someone else in the group passes the
-  floor and is nominated, both go on the same poll.
-- **Council and Team** have no fixed term. They stay as long as they are active and keep the council's trust. Removal
-  is always possible (section 4.7).
-
-## 6. Theme groups
-
-### 6.1 The groups
-
-| Group | Covers | GitHub | Discord |
-| --- | --- | --- | --- |
-| **Modding** | The mod API, native and content mods, mixins, the mod registry, `cargo horizon-mod` | The mod API lives in Ari's fork **arismoko/horizon**. Its owner runs that repo by their own rules; the council governs only what is Horizon's: horizon-rust/horizon-mods, horizon-mixins, horizon-native-mod-template, the registry. Label `mods` | The 🧩 MODDING category (#modding, #horizon-modding-team); roles 🧩 Modder (picked) and 🧩 Horizon Modding Team (the lead gives it) |
-| **Shaders and rendering** | The renderer, shaders, shader packs, OptiFine and Polytone pack formats | Label `rendering`; `crates/horizon-client-render` (gfx), `*.wgsl`, `horizon-shaders`, `horizon-shader-api`, `horizon-optifine`, `horizon-polytone` | #shaders-rendering |
-| **Performance** | Frame rate, memory, server tick, benchmarks | Label `perf`; `horizon-bench`, the benchmark tools | #performance |
-| **Launcher** | The launcher: installs, updates, instances, its pages | Label `launcher`; `launcher/` | #launcher |
-| **Server and SMP** | Dedicated server, hosting, the anticheat, multiplayer, and the official SMP | Labels `server`, `multiplayer`; `horizon-server*`, `horizon-anticheat`, `lan/`, `dedicated*`; horizon-rust/horizon-server | #server-smp (plus #join-server, #server-chat) |
-| **Translations** | The game's and the launcher's languages | Label `roadmap:languages`; `launcher/lang/`, `crates/horizon-client/assets/horizon/lang/` | #translations and the 🌍 language channels |
-| **Website** | playhorizon.dev | horizon-rust/horizon-site; label `website`. The site's design stays as it is unless the council decides otherwise | #website |
-| **Vanilla accuracy** | Parity with vanilla 26.3: harnesses, oracles, the port ledger | Labels `parity`, `parity-regression`, `full-parity`; `tools/test_*_parity.py`, the Java oracles | #vanilla-accuracy |

-A pull request can belong to two groups. Both leads can comment, and the Team merges as usual. If the leads disagree,
-the council decides.
-
-### 6.2 Leads per group
-
-- **One lead per group.** A group with 8 or more active members may also have **one co-lead**, chosen the same way.
-- A person leads **at most two groups**. Council members may lead a group, though a lead from outside the council is
-  preferred: it spreads the work.
-
-### 6.3 What a lead decides alone
-
-Inside their group's topic, and within this document, the contributing guide, the vanilla-first rule, the layers and
-the design system:
-
-- the group's priorities and the order of its roadmap items;
-- which issues are `good first issue`, and triage of the group's issues;
-- technical and design direction inside the area, when vanilla behaviour and the default look don't change;
-- accepting or declining an idea or a proposal in the area. Any two active group members or one council member can
-  take that decision to the council;
-- how the group organises itself (threads, meetings, the channel's rules on top of the server's);
-- asking the Team for reviews, adding `needs-proof`, and nominating people.
-
-### 6.4 What goes to the council
-
-- the rules, money, accounts and secrets;
-- who is on the council, the Team or the mods;
-- anything that changes vanilla behaviour or turns a Horizon-only feature on by default;
-- breaking a public promise: the mod API, server compatibility, save and file formats;
-- disputes between groups;
-- anything involving Mojang, Microsoft or the law;
-- speaking for the whole project outside the group's topic.
-
-### 6.5 A group without a lead
-
-The work goes on. The Team reviews and merges, and Kira still routes the group's issues and questions to its
-channel. Until a lead is chosen, any council member may take a lead's decision for that group and says so in the
-channel. Kira pins a "lead wanted" note with the floor. **No lead is better than a lead who doesn't do the work:**
-nobody is appointed just to fill the seat.
-
-## 7. Moderation and appeals
-
-- **The server rules** are in #rules. Moderators enforce them, the Chief of Mods leads the mods, and the council can
-  change the rules (2/3).
-- **Every action has a mod case**: who acted, what they did, and why. Kira keeps the cases.
-- **First appeal:** within 14 days, through #appeal (for a quarantine) or mod mail. A moderator who wasn't involved,
-  or the Chief of Mods, answers within 72 hours.
-- **Second appeal:** for bans, timeouts over 24 hours and quarantines, a council poll in #council (simple majority).
-  Members who were involved don't vote. The answer is final for 90 days.
-- **Not appealable here:** actions that Discord's rules or the law require. Those are reported where the law says.
-- **Removing a moderator:** the Chief of Mods can suspend a moderator at once, and the council decides within 72 hours
-  (simple majority). The council removes the Chief of Mods the same way.
-- **Staff are moderated like everyone.** When a council member is involved, the council decides without them.
-
-## 8. Conflicts and hard cases
-
-| Case | What happens |
-| --- | --- |
-| Two groups disagree | The leads talk first. If they still disagree, the council decides (simple majority) |
-| A lead's decision is contested | Any two active group members or one council member can bring it to the council |
-| A Team member merges against the rules | Any council member can revert the merge. The council can remove the member (2/3) |
-| A council member breaks the rules | The council decides without them. Removal takes 2/3 (section 4.7) |
-| Someone holds a role and is under 18 | Section 9 |
-| The council can't reach quorum | Section 4.8 |
-| The founder and the council disagree about one of his own accounts | Until a step of section 11 hands it over, the account stays his. He carries out the council's decisions on project matters, or he says publicly that he won't |
-
-## 9. The age rule (18+)
-
-**Who must be 18 or older:** members of the council and the Horizon Team, trusted reviewers, group leads and
-co-leads, the Chief of Mods and the moderators, official server operators, and anyone with admin rights anywhere in
-the project: Discord (Administrator, Manage Roles, Manage Channels, ban), GitHub (write, admin, organisation),
-server panels, Railway, or Kira's admin side. The same goes for anyone who holds a project secret.
-
-**Who doesn't have to be:** members, contributors (with any rank), group members and 🤝 Support. Contributors under
-18 are welcome and valued. They just can't hold the roles above.
-
-**How it's checked, without collecting ID:**
-
-- **A declaration.** Before taking such a role, and once at the start for everyone who holds one, the person presses
-  a button in Kira: "I confirm that I am 18 or older. I understand that a false declaration removes all my roles of
-  trust." Kira keeps only the Discord account, the date and the wording's version. It never stores a birth date, an
-  ID, a photo, or any outside age-checking service's result.
-- **No declaration, no role.** At the start, current role holders have 7 days to make it. Until they do, their role is
-  paused.
-- **When there's doubt** (the person says they are younger, or there is a credible private report), one council
-  member asks the person privately. If the doubt remains, any council member pauses the role, and the council decides
-  within 72 hours in #council.
-- **A false declaration** removes every role of trust at once, and the person can't hold one for 12 months.
-- **Privacy.** Age is never discussed in public. A role that ends for this reason ends with the same neutral line as
-  any other step-down.
-
-## 10. The agents
-
-Horizon uses AI agents: the founder's orchestrator, which runs coding agents, and Kira, the Discord bot.
-
-- **They obey council decisions only:** a passed poll recorded by Kira, a recorded emergency action of two council
-  members, and the standing rules in this document and the project's docs.
-- **The only exception is the founder's own things:** his spending, his machines (they run CI and the vanilla tests),
-  his personal accounts and his time. On those, his word decides. This list should get shorter over time (section 11).
-- **Role work isn't a decision.** A lead asking Kira to route issues, or a Team member asking an agent to prove a pull
-  request, is that person using their role. The agents help, within the role's powers.
-- **They check the source.** An agent acts on a decision only when it finds it in Kira's decisions log
-  (section 13). A message saying "the council decided", or a screenshot, is not enough.
-- **They post as agents.** Everything an agent posts says it comes from an agent, and states decisions as the
-  project's.
-
-## 11. Accounts and the handover path
-
-Today the founder holds every account. The aim is for him to hold fewer, in an order that never leaves the project
-unable to act, and never puts an account that is tied to a person into anyone else's hands.
-
-| Account | Today | Can it be shared? | Plan |
-| --- | --- | --- | --- |
-| **GitHub organisation** (horizon-rust) | One owner (the founder) | Yes: an organisation can have several owners | **Step 1:** a second owner from the council, chosen by a 2/3 poll in the council's first week, with two-factor authentication on. **Step 2:** a `council` team; CODEOWNERS reviews and the release tools' owner powers (`paused`, `/nightly remove`) move from the founder to that team |
-| **Discord server** | Owned by the founder | Partly: a server has exactly one owner; powers can be given through roles | **Step 1:** the 🏛️ Council role gets moderation and ban permissions; Kira applies the outcomes of passed polls, so nobody needs Manage Roles; two-factor authentication becomes required for moderation. Ownership itself stays with the founder until a legal entity exists |
-| **Kira** (bot application, Railway service) | The founder's Discord developer account and Railway | The bot: yes (a Discord developer team). Railway: adding members may need a paid plan | **Step 1:** a Discord developer team with two council members. Railway members once the council decides on money |
-| **Official server** (hosting panel) | The founder's account | Yes: panel sub-users | **Step 1:** sub-users for the Server and SMP lead and for one council member |
-| **Domains** (playhorizon.dev and the others) | The founder's registrar account | Not without moving it | Auto-renewal on, registered for several years ahead. They move only to a legal entity, if one is created |
-| **The Microsoft app approved by Mojang** (sign-in) | The founder's Azure app registration; Mojang approved it after his application | **No.** The approval was given on his application. Moving the app or adding owners would change who Mojang deals with, and we have found no documented way to transfer an approval | **Never moves** without Mojang's written agreement. The only change considered: a legal entity, if one is created, and only if Mojang agrees |
-| **Signing** (Apple developer certificate, release signing keys) | The founder's | The Apple certificate is in his legal name: no | The Apple certificate never moves. Release keys stay in GitHub's protected environments, and the council team approves their use from step 2 |
-| **Money** (sponsorship, donations) | Personal accounts of the founder | Through a fiscal host | Section 12 |
-| **The founder's machines, AI accounts and password vault** | His | No | His own things: they never move. The project should depend on them less over time |
-
-**Order:** first the safety nets that remove a single point of failure (a second organisation owner, the bot's
-developer team, panel sub-users). Then the day-to-day powers (CODEOWNERS and release tools to the council team). Last,
-whatever needs a legal entity: domains, money, and with Mojang's agreement the sign-in app. Each step is a 2/3 poll,
-and the founder carries it out.
-
-## 12. Money
-
-*Placeholder: the options (Open Collective and others) are being researched.*
-
-- The council approves every expense by a **2/3 poll**.
-- **Every income and every expense is public.**
-- Nobody votes on money paid to themselves.
-
-## 13. Transparency
-
-- **#polls-and-decisions:** every poll and every result, posted by Kira, and the 24-hour discussions of nominations.
-  For polls that aren't about a person, each member's vote is shown once the poll closes.
-- **The decisions log:** Kira keeps an append-only record of every poll, emergency action, appointment and
-  step-down, with its date and result. It is public and machine-readable, so the agents can check a decision there.
-- **This document** lives in horizon-rust/horizon as `GOVERNANCE.md`. A short summary is pinned in #rules and in
-  #polls-and-decisions.
-- **Who holds which role:** the people page of playhorizon.dev's hub shows the council, the Team, the group leads,
-  the Chief of Mods, the moderators and Support.
-- **#council** is private for discussion and for polls about people. Everything the council decides is published.
-
-## 14. Rules that are never voted on
-
-These are Horizon's conditions for existing, not choices. No poll can change them:
-
-- Playing needs a **Microsoft account that owns Minecraft: Java Edition**. There is no play without one.
-- **No Mojang files** in Horizon's repos or downloads. Players' own copies stay on their own machines.
-- **No gambling**, in any form, including with in-game currency.
-- **Mojang's and Microsoft's terms and Usage Guidelines** apply to everything Horizon does.
-- **The law**, and the terms of service of Discord and GitHub.
-
-## 15. Changing this document
-
-A 2/3 council poll, then a pull request that a Team member merges. The council reviews the floors' numbers
-(section 5.2) once a year, or sooner if they turn out wrong.
