+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official email address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+**whitlocktech@gmail.com**.
+
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.1, available at
+[https://www.contributor-covenant.org/version/2/1/code_of_conduct.html][v2.1].
+
+Community Impact Guidelines were inspired by

+# Contributing to Runic Gateway — Documentation
+
+Thanks for your interest in contributing! This repo is the **central
+documentation** for the Runic Gateway platform — design docs, the protocol spec,
+integration guides, and research, extracted from the code repos so they live in
+one place.
+
+By participating you agree to abide by our
+[Code of Conduct](CODE_OF_CONDUCT.md).
+
+## Ways to contribute
+
+- **Report an error** (something wrong, outdated, or unclear) or **request new
+  documentation** through the
+  [issue tracker](https://gitea.whitlocktech.com/RunicGateway/docs/issues)
+  (issue templates are provided).
+- **Fix or expand the docs** by opening a pull request (see below).
+- **Never** report a security vulnerability in a public issue — see
+  [SECURITY.md](SECURITY.md).
+
+## Working on the docs
+
+Everything here is Markdown — no build step. Just edit the relevant file and
+preview it in any Markdown viewer (or on Gitea).
+
+```
+website/   docs for the shard website (Node/Express + MariaDB + React/Vite)
+link/      docs for the ServUO bridge (C# plugin + Rust sidecar)
+```
+
+Guidelines:
+
+- Keep documents in the folder matching their subsystem (`website/` or `link/`).
+- These docs are the **authoritative** copy of the protocol and design; when you
+  change behavior in a code repo, update the matching doc here in the same or a
+  follow-up PR so the spec and implementation stay in sync.
+- Use relative links between docs, and check that any links you add resolve.
+- Prefer clear prose and tables over screenshots where possible.
+
+## Branch & PR workflow
+
+1. Branch from `main` with a descriptive name (`docs/…`, `fix/…`, `chore/…`).
+2. Keep changes focused; small PRs are easier to review.
+3. Push and open a pull request against `main`. Fill out the PR template,
+   including the **AI-assisted contributions** disclosure.
+4. A maintainer will review; address feedback with follow-up commits.
+
+### Commit messages
+
+We use [Conventional Commits](https://www.conventionalcommits.org/) —
+`type(scope): summary` (e.g. `docs(link): clarify town-crier caps`).
+
+## AI-assisted contributions (disclosure required)
+
+This project is developed openly with AI assistance, and we ask the same
+transparency of everyone. **If you used an AI tool** (Claude, Copilot, ChatGPT,
+Cursor, etc.) to help produce a contribution, you must disclose it:
+
+- Tick the AI-usage box in the pull-request template and name the tool(s).
+- Mark AI-authored commits with a trailer, e.g.
+  `Co-Authored-By: Claude <noreply@anthropic.com>` or `Assisted-By: <tool>`.
+- You remain responsible for every line you submit: review it, understand it,
+  and make sure it is accurate and that you have the right to contribute it.
+
+Disclosed AI assistance is welcome. Undisclosed AI-generated contributions are
+not, and may be closed.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>

+    This program is free software: you can redistribute it and/or modify

+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read

+# Security Policy
+
+Thank you for helping keep Runic Gateway and its users safe.
+
+## Reporting a vulnerability
+
+**Please do not report security vulnerabilities through public issues, pull
+requests, or the wiki.** A public report tips off attackers before a fix is
+available.
+
+Instead, report privately by email to:
+
+**whitlocktech@gmail.com**
+
+Please include as much of the following as you can:
+
+- The repository and component affected.
+- The type of issue (e.g. authentication bypass, injection, secret exposure,
+  remote code execution, denial of service).
+- Step-by-step instructions to reproduce, and a proof-of-concept if you have one.
+- The impact — what an attacker could do with it.
+- Any suggested remediation.
+
+You will receive an acknowledgement of your report, typically within a few days.
+We will keep you informed as we investigate and work toward a fix, and we are
+happy to credit you in the release notes once the issue is resolved (let us know
+if you would prefer to remain anonymous).
+
+## Scope
+
+Runic Gateway is a self-hosted platform made up of several components:
+
+| Component | Repo | Network exposure |
+|---|---|---|
+| Website (site + admin + API) | `RunicGateway/website` | Internet-facing (behind a reverse proxy) |
+| uo-link sidecar | `RunicGateway/link` | The only network-facing part of the game bridge |
+| ServUO plugin | `RunicGateway/servuo-plugins` | Loopback only — dials the sidecar on `127.0.0.1` |
+| Documentation | `RunicGateway/docs` | Content only |
+
+Because instances are self-hosted, the security of any given deployment also
+depends on how it is configured and operated — strong secrets (`JWT_SECRET`,
+`SECRET_ENC_KEY`, database and admin passwords), a correctly configured reverse
+proxy and `TRUST_PROXY`, and keeping the shard itself unreachable from the
+internet (only the sidecar should be exposed). See each repo's README for the
+security model.
+
+## Supported versions
+
+This project is developed continuously and does not maintain long-term release
+branches. Security fixes land on `main`; please run a recent build.

+# Android App Links — implementation spec
+
+Status: **implementation spec (M9 follow-up).** Stacks on the native SSO bridge (M9 Part 2):
+the app already handles the **custom-scheme** callback `runicgateway://auth/callback`, and that stays
+the permanent default and universal fallback. App Links are an **opt-in hardening** layered on top —
+a verified `https://` callback that only the domain's real owner can claim.
+
+Read alongside: the "Mobile SSO Authorization Bridge" section of
+[`../website/BACKEND_DESIGN.md`](../website/BACKEND_DESIGN.md) (endpoints/tables/allowlist), and
+[`PLAN.md`](./PLAN.md) §4.2 / §9 (the app milestone). This spec matches what ships on the
+`feat/mobile-app-links` (website) and `feat/app-links` (android) branches.
+
+---
+
+## 1. The problem it solves
+
+The mobile SSO bridge redirects the browser back to the app with a one-time code:
+
+```
+runicgateway://auth/callback?code=…&state=…
+```
+
+A **custom URI scheme** is fine for a self-hosted internal client, but it is not *owned* by anyone:
+any other Android app can register an intent-filter for `runicgateway://auth/callback` and, if chosen
+by the user, intercept the callback. The code is single-use, PKCE-bound (Layer B), and short-lived —
+so an interceptor still cannot complete `/exchange` without the app's `code_verifier` — but a hijacked
+callback is still a denial-of-service and a phishing surface we would rather close.
+
+**Android App Links** (verified `https://` deep links) close it: the OS only routes an `https://`
+link to an app that has proven, via a file served from *that domain*, that it owns the app. An
+attacker cannot serve that file on a domain they do not control.
+
+## 2. Why this is harder here than in a normal app
+
+RunicGateway is **self-hosted per shard**. There is no single canonical domain — every shard owner
+runs the website on **their own** domain (`play.exampleshard.com`, `uo.anothershard.net`, …). App
+Links verification is **per-domain**: the domain must serve
+
+```
+https://<shard-domain>/.well-known/assetlinks.json
+```
+
+asserting the Android app's **package name** + **signing-certificate SHA-256 fingerprint**.
+
+That is only half the problem. The other half is an Android platform constraint that decides the whole
+shape of the app side:
+
+> **`android:autoVerify` needs a *literal* host at build time.** An intent-filter's `<data android:host>`
+> is a static string in the merged manifest; there is no "any host" or runtime host. A **single
+> published multi-tenant APK therefore cannot autoVerify an open-ended set of shard domains** — the set
+> is not known when the APK is built.
+
+So App Links here are **not** a drop-in replacement for the custom scheme. They split into two pieces
+that ship independently:
+
+1. **Server (`assetlinks.json`) — shippable now, benefits any App-Links-capable build.** Every shard
+   can auto-serve its Digital Asset Links statement behind an admin toggle. This is a pure add and is
+   implemented on `feat/mobile-app-links`.
+2. **App (`autoVerify` intent-filter) — a *build-time* opt-in.** Because the host must be baked in,
+   App Links are available to:
+   - a **white-label / first-party build** that bakes one shard's host (`-PappLinkHost=play.myshard.com`);
+   - a future **canonical relay domain** (`runicgateway.app`, PLAN §14 — *not yet secured*) that all
+     shards could bounce their final callback through, autoVerified by the generic build.
+
+   The **generic multi-tenant build bakes no host and stays custom-scheme-only** — correct and safe.
+
+The custom scheme is never removed. It is the fallback on every build, for every shard, always.
+
+## 3. Server design — `feat/mobile-app-links`
+
+### 3.1 Auto-served `assetlinks.json`
+
+- **Route:** `GET /.well-known/assetlinks.json`, served at the **web root** (outside `/api/v1`, before
+  the SPA catch-all) in `server/src/app.js`.
+- **Gate:** the admin setting `mobile_app_links_enabled` (default **off**). Off ⇒ the route **404s** and
+  the app stays on the custom scheme for that shard. On ⇒ the shard opts into App Links.
+- **Body:** the Digital Asset Links statement for the fixed package `com.runicgateway.app` and the
+  release signing cert SHA-256 fingerprint(s):
+
+  ```json
+  [
+    {
+      "relation": ["delegate_permission/common.handle_all_urls"],
+      "target": {
+        "namespace": "android_app",
+        "package_name": "com.runicgateway.app",
+        "sha256_cert_fingerprints": ["AB:CD:…"]
+      }
+    }
+  ]
+  ```
+
+- **Fingerprint source:** env `MOBILE_APP_CERT_SHA256` — comma-separated (supports **cert rotation** and
+  a debug + release cert during testing). It is a **constant of the published app**, identical for every
+  shard, so it is a shipped/env default, not something each owner types. The package name is likewise
+  fixed (`MOBILE_APP_PACKAGE`, default `com.runicgateway.app`).
+- **Enabled but no fingerprint configured ⇒ 404** (+ a one-time warn): serving a statement with no
+  fingerprint asserts nothing and would only mislead the verifier.
+- Response is `application/json`, `Cache-Control: public, max-age=3600` (the Play verifier and the OS
+  re-fetch it; it changes only on a cert rotation).
+
+### 3.2 Redirect-URI allowlist extension
+
+`mobileSso.controller` validates the app's `redirect_uri` by **exact match** against
+`MOBILE_AUTH_REDIRECT_URIS` (default `runicgateway://auth/callback`). App Links add exactly one more
+acceptable value, and **only when the toggle is on**:
+
+- When `mobile_app_links_enabled`, `/start` additionally accepts the **self-origin** HTTPS callback
+  `https://<request-host>/mobile/callback` (derived from the request/`APP_BASE_URL`, never from
+  attacker-controlled input). Still **exact match** — never a prefix match.
+- The static custom-scheme allowlist is never narrowed; the HTTPS entry is *additive*.
+- No new table or schema: the check reads the one boolean setting.
+
+### 3.3 Public settings advertise the capability
+
+`settings.getPublic()` gains `mobileAppLinks: <bool>` (mirrors the toggle) so a client can tell whether
+a shard opted in before requesting an HTTPS `redirect_uri` (a white-label build uses it to avoid asking
+for a callback the server would reject).
+
+## 4. App design — `feat/app-links`
+
+### 4.1 Build-time host (`appLinkHost`)
+
+- Gradle property `appLinkHost` (default empty). Wired in `app/build.gradle.kts` into **both**:
+  - `BuildConfig.APP_LINK_HOST` — read by `SsoAuthManager` to decide the redirect;
+  - `manifestPlaceholders["appLinkHost"]` — substituted into the App Link intent-filter's host.
+- **Default (generic build):** empty ⇒ `BuildConfig.APP_LINK_HOST = ""` and the placeholder falls back
+  to the reserved sentinel `runic-gateway.invalid` (RFC 6761 — never resolves), so the `autoVerify`
+  filter is **inert**: it matches no real link and verification simply never succeeds. No custom-scheme
+  behaviour changes.
+- **White-label build:** `./gradlew assembleRelease -PappLinkHost=play.myshard.com` bakes that one host
+  into the filter and enables the HTTPS redirect for that host.
+
+### 4.2 Manifest
+
+A second intent-filter on `MainActivity`, alongside the unchanged custom-scheme one:

+### 4.3 `SsoAuthManager` (pure Kotlin, unit-tested on the JVM)
+
+- **Redirect selection in `buildStartUrl`:** request the HTTPS `redirect_uri`
+  `https://<pairedHost>/mobile/callback` **iff** `BuildConfig.APP_LINK_HOST` is non-blank *and* equals
+  the paired base-URL host (case-insensitive); otherwise the fixed custom-scheme `REDIRECT_URI`. A
+  white-label build that bakes the host is responsible for enabling the server toggle too (§3.2).
+- **Verified-callback matcher + host-trust check:** a new `matchesAppLinkCallback(scheme, host, path)`
+  accepts only `scheme == https`, `path == /mobile/callback`, and **`host == the paired base-URL host`**.
+  The paired-host equality is defense-in-depth: even though `autoVerify` already means only a real,
+  opted-in shard domain can route here, the app still refuses any HTTPS callback whose host isn't the
+  shard it is currently paired to.
+- The rest is unchanged: both matchers feed the *same* `complete(state, code, error)` → `/exchange` →
+  `SessionManager.onSignedIn`. There is no second auth path.
+
+### 4.4 `MainActivity`
+
+`handleSsoCallback` routes a VIEW intent through **`matchesCallback(...) || matchesAppLinkCallback(...)`**;
+everything downstream (state check, exchange, sign-in) is shared. Custom-scheme and App Link callbacks
+are indistinguishable past the edge.
+
+## 5. Turning it on for a shard
+
+1. Publish/point the app build at the shard host (`-PappLinkHost=<host>`) — or use the generic build and
+   leave App Links off.
+2. Set `MOBILE_APP_CERT_SHA256` (release cert fingerprint) in the website env.
+3. Admin → Shard/Settings: enable **App Links** (`mobile_app_links_enabled`).
+4. Verify `https://<host>/.well-known/assetlinks.json` returns the statement; confirm Android verifies
+   (`adb shell pm get-app-links com.runicgateway.app`).
+
+If any step is skipped the app transparently keeps using the custom scheme — nothing breaks.
+
+## 6. Testing
+
+- **Server (`node --test`):** route 404s when the toggle is off; 404s when on but no fingerprint;
+  returns the correct statement + content-type when on and configured; the redirect allowlist accepts
+  `https://<host>/mobile/callback` only when enabled and rejects it otherwise (custom scheme always
+  accepted).
+- **App (JVM unit tests):** `matchesAppLinkCallback` accepts only https + `/mobile/callback` + the paired
+  host and rejects a foreign host / http / wrong path; `buildStartUrl` requests the HTTPS redirect only
+  when the baked host matches the paired host, else the custom scheme.
+
+## 7. What does *not* change
+
+- The bridge's server design (PKCE Layer A/B, single-use codes, `/start` + `/exchange`) is untouched;
+  App Links are *one more allowlist entry* + *one static file route*. That is the whole point of keeping
+  the allowlist exact-match and configurable from day one.
+- The custom scheme remains on every build and is the permanent fallback.
+- No change to `servuo-plugins/` — App Links are entirely a website ↔ app concern.

+# Android app — trusted devices & recovery codes (live smoke test)
+
+Screenshots from a live end-to-end smoke test of the trusted-device + MFA feature on
+the Android client (app PR `RunicGateway/Android-app#23`), captured against the local
+Node server (`127.0.0.1:3000`) and a `uomysticmoon` MariaDB, on an API 36 emulator.
+See `../PLAN.md §4.1.1` for the design and `../../website/TRUSTED_DEVICES_MFA.md` for
+the canonical contract.
+
+| # | Screenshot | Shows |
+|---|---|---|
+| 1 | [`01-login-2fa-trust-device.png`](01-login-2fa-trust-device.png) | The `401 { totpRequired }` login step: the **authentication code** field, the **"Use a recovery code instead"** toggle, and the **"Trust this device (skip codes for 30 days)"** checkbox (ticked). |
+| 2 | [`02-account-security-section.png`](02-account-security-section.png) | The new **Security** section on the account screen linking to Trusted devices and Recovery codes. |
+| 3 | [`03-trusted-devices.png`](03-trusted-devices.png) | The **Trusted Devices** screen listing this device (`Google sdk_gphone64_x86_64` — the `device_name` sent at login) with revoke / trust-this-device / untrust-all. |
+| 4 | [`04-recovery-codes-show-once.png`](04-recovery-codes-show-once.png) | The **Recovery Codes** screen after a password-stepped regenerate: the one-time batch shown once with copy / share, and the updated remaining count. |
+| 5 | [`05-recovery-code-login.png`](05-recovery-code-login.png) | Signing in with a **single-use recovery code** instead of the authenticator code. |
+
+## Verified flows (all passed)
+
+1. **2FA login + "Trust this device"** → `200`, trust token stored; server logged `device trusted`.
+2. **Trust survives logout** — after signing out, a **password-only** sign-in skipped the
+   TOTP step entirely (server: a clean `200` with **no** preceding `401 totpRequired`).
+   This is the headline behaviour: the trust token is *only* consulted at a fresh login,
+   so it must outlive logout (see PLAN §4.1.1).
+3. **Trusted Devices** — list, and the device's `last_used` stamp advancing after the
+   trust-skip login.
+4. **Untrust all** — cleared the server rows **and** the local token; the next
+   password-only sign-in correctly required the TOTP step again (server: `401`).
+5. **Recovery codes** — generate (password step-up, shown once) and a successful
+   **recovery-code login** (server: `mobile login via recovery code` → `200`).

+# Android theme plan — mirroring the website frontend
+
+This is a summary of the **website frontend theme** (source of truth:
+`website/client/src/styles/theme.css`, applied at runtime by
+`website/client/src/contexts/SiteContext.jsx`) so the native Android client can
+present a visually consistent brand. Where the web uses CSS custom properties,
+the Android equivalent is a Compose `MaterialTheme` `ColorScheme` + `Typography`.
+
+## Overall character
+
+A **dark, moody, "arcane fantasy" theme** — deep blue-black backgrounds, muted
+slate-blue accent, parchment-white text, and an engraved serif display face. It
+reads like a leather-and-moonlight fantasy ledger, not a bright consumer app.
+There is **no light mode** on the web; the app should ship dark-only to match.
+
+## Color tokens
+
+The web theme is a flat set of CSS variables under `:root`. Map them to Compose
+as follows (hex is authoritative):
+
+| Web token         | Hex        | Role                                   | Compose slot (suggested)      |
+|-------------------|------------|----------------------------------------|-------------------------------|

+| `--bg-deep`       | `#0b0f14`  | Deepest surface / on-accent text       | `surfaceDim` / `onPrimary`    |
+| `--panel-a`       | `#192231`  | Card gradient top                       | `surface`                     |
+| `--panel-b`       | `#141a21`  | Card gradient bottom                    | `surfaceContainer`            |

+| `--mode-maint`    | `#e6c26a`  | "Maintenance" status (amber)           | warning                       |
+
+### Semantic / status colors (used in badges, diffs, moderation)
+
+- **Success / published / live:** green `#5fb98a` (fills at ~16–22% alpha, text `#7fd0a4`).
+- **Warning / maintenance / moderation (kick/mute/warn):** amber `#e0b070` / `#e6c26a`.
+- **Danger / ban / red-link / errors:** desaturated red `#d98b84` (borders `#6e3b38`).
+- **Admin badge:** near-white `#d8e2ef` on `#3a4a5e`.
+
+## Branding is data, not code
+
+The `--accent` value is **overridden at runtime** per shard instance. On the web,
+`SiteContext` reads `brand.accent` from the site settings API and sets the CSS
+variable, so one build reskins for any shard. **The Android app should do the
+same:** fetch the brand payload (name, `accent`, colors, logo/hero/favicon) from
+the website API and derive the `primary` color at runtime rather than hardcoding
+`#7f99bd`. Default to `#7f99bd` when the brand payload is absent/offline.
+
+## Typography
+
+Three font families, by role:
+
+- **Display** (`--display`): **Cinzel**, falling back to Georgia serif — an
+  engraved Roman capitals face used for the logo, `h1`/`.h1`, and prose
+  `h2`/`h3`. Bundle Cinzel as an app font; this face carries the brand.
+- **Serif body** (`--serif`): **Georgia / Times New Roman** — default body and
+  prose text; `line-height ≈ 1.6`.
+- **Sans** (`--sans`): **Helvetica Neue / Arial** — UI chrome: buttons, pills,
+  form labels, table headers, badges, meta. Labels/eyebrows/kickers are
+  UPPERCASE with wide letter-spacing (`0.1–0.18em`) and small (0.68–0.86rem).
+
+Heading scale is fluid on web (`h1` clamps ~2.4–3.6rem); pick fixed Material type
+scale equivalents (e.g. display for `h1`, headline for `h2`, title for `h3`).
+
+## Shape, elevation & motion
+
+- **Corners:** cards/panels `10–12px` radius; inputs/small elements `8px`;
+  pills and buttons are **fully rounded** (`999px` / capsule).
+- **Cards:** vertical gradient `--panel-a → --panel-b`, 1px `--line` border, soft
+  drop shadow (`0 14px 34px rgba(0,0,0,0.3)`). On hover the web lifts `-3px` and
+  brightens the border to `--accent` — translate to a pressed/focused accent
+  border on Android.
+- **Buttons:** primary = bright fill (`--accent-bright`) with dark text;
+  ghost/secondary = translucent dark fill with accent-on-hover border.
+- **Motion:** short, subtle transitions (0.12–0.18s). Keep animations understated.
+
+## Signature accents (nice-to-have)
+
+- The **"moon"** motif: a radial-gradient sphere (`#eef3f8 → #9fb0c6 → #5d6e88`) —
+  a small brand flourish worth reproducing.
+- Accent-tinted focus rings and left-border "note" callouts
+  (`border-left: 3px solid --accent` over a translucent `--blue` background).
+
+## Implementation note for Compose
+
+Define one `darkColorScheme(...)` from the table above, a `Typography` binding the
+three families, and a `Shapes` set (`small = 8.dp`, `medium = 10.dp`, capsule for
+buttons). Load `accent` from the brand API into a state holder and rebuild the
+`primary` (and derived `primaryContainer`) at runtime so a shard's custom accent
+flows through the whole UI — exactly as `SiteContext` does on the web.

+# SonarQube static analysis
+
+Each code repo in the Runic Gateway org reports static-analysis results to the
+self-hosted **SonarQube** server for review. Analysis is **non-blocking**: it
+runs on push to `main` (i.e. *after* merge), never on pull requests, so it never
+gates a PR. It complements each repo's PR gate and release pipeline — it only
+feeds the dashboard.
+
+## Server
+
+- **URL:** `https://sonar.whitlocktech.com`
+- Each repo is a separate SonarQube project, keyed as below.
+
+## Projects
+
+| Repo | Project key | Sources analysed | Language |
+|---|---|---|---|
+| `website` | `runic-gateway-website` | `server/src`, `client/src`, `bot/src` | JS/TS |
+| `link` | `runic-gateway-link` | `sidecar/src` | Rust |
+| `Android-app` | `runic-gateway-android-app` | `app/src/main` | Kotlin |
+
+## How it's wired
+
+Each repo carries two files, identical in shape across repos:
+
+- **`sonar-project.properties`** (repo root) — declares the project key, sources,
+  tests, and exclusions. The Sonar scanner reads this.
+- **`.gitea/workflows/sonarqube.yml`** — a `SonarQube` workflow that, on push to
+  `main` (and via manual `workflow_dispatch`), checks out with full history
+  (`fetch-depth: 0`, needed for accurate blame + "new code") and runs
+  `sonarsource/sonarqube-scan-action@v4`.
+
+The scan is **source-based** — it does not build the project or run a language
+toolchain, so the workflows are lightweight (checkout + scan only). Richer
+signals (Rust Clippy, Android Lint, JaCoCo coverage) are left as documented,
+commented-out enrichment in each repo's `sonar-project.properties`; enable them
+per repo when wanted.
+
+## One-time setup per repo (Gitea UI → Repo → Settings → Actions)
+
+Both are consumed by the scan action via `env:` in the workflow:
+
+- **Secret `SONAR_TOKEN`** — a SonarQube *Analysis* token (My Account →
+  Security in SonarQube; project-scoped or global).
+- **Variable `SONAR_HOST_URL`** — the SonarQube base URL reachable from the
+  self-hosted runner. Kept as a **variable, not committed**, so the internal
+  address stays out of git.
+
+The self-hosted `ubuntu-latest` runner must be able to reach `SONAR_HOST_URL` on
+the network. Nothing waits on the SonarQube Quality Gate, so a failing gate does
+not fail the job — check the dashboard.
+
+## Adding a new repo
+
+1. Create the project in SonarQube; note its key.
+2. Add `sonar-project.properties` (copy an existing repo's, adjust key + sources).
+3. Add `.gitea/workflows/sonarqube.yml` (copy verbatim — it's language-agnostic).
+4. Set the `SONAR_TOKEN` secret and `SONAR_HOST_URL` variable in the repo's
+   Gitea Actions settings.

+# Website — Architecture
+
+How the pieces of `RunicGateway/website` fit together. The React SPA and the native mobile app
+talk to one Express backend (`router → controller → model → db`), which persists to MariaDB and
+bridges to the live game world **only** through the **uo-link** sidecar. The ServUO shard itself is
+never internet-facing — it dials out to the sidecar over loopback, and only the sidecar is exposed.
+
+This is the canonical copy of the diagram; the same diagram is embedded in the website's
+[`README.md`](https://gitea.whitlocktech.com/RunicGateway/website/src/branch/main/README.md#architecture).
+See [BACKEND_DESIGN.md](BACKEND_DESIGN.md) for the full API / schema / security contract, and
+[`docs/link/`](../link/) for the wire protocol between the sidecar and the shard.

+## Notes on the diagram
+
+- **One backend, layered.** Every request flows `middleware → router → controller → model → db`.
+  Web browsers authenticate with an httpOnly JWT cookie; the native app uses short-lived bearer
+  access tokens plus rotated, hashed, revocable refresh tokens; SSO (Google/Discord/OIDC) is
+  link-only and PKCE-guarded. All three surfaces resolve to the *same* session model via the session
+  layer, and admin routes are re-validated against the DB on every request.
+- **The shard is never reachable.** The ServUO shard *dials out* over loopback TCP `127.0.0.1:7788`
+  (newline-delimited JSON) to the uo-link sidecar; only the sidecar is exposed, and only the backend
+  talks to it. Every backend→sidecar call carries `Authorization: Bearer <token>` and an
+  `X-UOLink-Version` header (a protocol mismatch fails fast with `409`). The REST client
+  (`uoLinkClient.js`) never throws — every call returns `{ ok, data, status }` — so the site degrades
+  gracefully when the shard is down.
+- **Two ways in from the sidecar.** Live game events arrive over an outbound **WebSocket** and are
+  routed by the `shardIngest.js` dispatcher (state-changing kinds update `shard_*` tables, notable
+  kinds append to `shard_events`, high-frequency kinds only update state). Point-in-time reads and
+  commands go over **REST** through `uoLinkClient.js`.
+- **Sensitive events stay private.** Ingested events fan out to browsers over two **SSE** channels —
+  a public allowlist stream and an admin-only stream that additionally carries staff audit, cheat
+  detection, and login-attempt events. The allowlist split is a security boundary; sensitive kinds
+  can never leak onto the public channel.
+- **Secrets at rest.** OAuth client secrets, the uo-link token, and the Gmail refresh token are
+  AES-256-GCM encrypted via `secretBox.js` (keyed by `SECRET_ENC_KEY`). The uo-link token is
+  write-only in the API — never returned to any client.

+### mobile_auth_sessions / mobile_auth_codes  — mobile SSO bridge (M9)
+
+Two short-lived, self-pruning tables that bridge a browser SSO redirect flow to a native client. They
+carry the **app ↔ website** PKCE + CSRF state (a *second* PKCE layer, distinct from the website ↔ IdP
+PKCE the `sso_tx` cookie already carries) and the one-time authorization code the app exchanges for
+bearer tokens. Neither holds a secret in the clear — the PKCE `code_challenge` is a hash by
+construction, and the authorization code is stored as a **sha256 hash only** (same pattern as
+`user_invites` / `password_resets` / `mobile_refresh_tokens`).
+
+`mobile_auth_sessions` — one row per `/auth/mobile/sso/start`:
+
+| col | type | notes |
+|---|---|---|
+| id | INT PK AUTO_INCREMENT | |
+| session_id | CHAR(36) UNIQUE | opaque uuid; carried inside the signed `sso_tx` (mode `mobile`) so the callback can find this row |
+| provider | VARCHAR(40) NOT NULL | provider id validated enabled at `/start` |
+| code_challenge | VARCHAR(255) NOT NULL | app-supplied PKCE S256 challenge (base64url); verified at `/exchange` |
+| redirect_uri | VARCHAR(255) NOT NULL | the requested app callback — **exact-match** against the allowlist (never prefix) |
+| state | VARCHAR(255) NOT NULL | app-generated opaque CSRF value, echoed on the callback for the app to verify |
+| status | ENUM('pending','completed','consumed') DEFAULT 'pending' | `pending`→`completed` when the code is minted; `consumed` after a successful exchange |
+| user_id | INT NULL FK→users(id) ON DELETE CASCADE | set once SSO resolves the account |
+| expires_at | DATETIME NOT NULL | short (~10 min — one redirect round-trip incl. TOTP) |
+| created_at / used_at | DATETIME | `used_at` stamped at exchange |
+
+`mobile_auth_codes` — one row per completed SSO callback (the code the app redeems):
+
+| col | type | notes |
+|---|---|---|
+| id | INT PK AUTO_INCREMENT | |
+| code_hash | CHAR(64) UNIQUE | sha256 hex of the opaque ≥128-bit code; the raw code never touches the DB |
+| user_id | INT NOT NULL FK→users(id) ON DELETE CASCADE | the authenticated account |
+| session_id | CHAR(36) NOT NULL | the owning `mobile_auth_sessions.session_id` (ties the code to its PKCE challenge) |
+| expires_at | DATETIME NOT NULL | very short (~5 min) |
+| used_at | DATETIME NULL | set on first successful exchange — **single use** (a reused code fails) |
+| created_at | DATETIME | |
+
+Both self-prune (indexed `expires_at`): a best-effort sweep runs at boot beside the existing
+`revoked_sessions` prune, and each bridge write opportunistically deletes expired rows — so no cron
+infra is added (same approach as `revoked_sessions`).
+
+**`mobile_refresh_tokens` additions (M9).** Two nullable columns are added to support the device
+list/revoke surface: `device_name VARCHAR(100) NULL` (a friendly label) and `last_used_at DATETIME
+NULL` (bumped on each refresh). Existing rows get them via the schema's ALTER section; the token model
+is otherwise unchanged.
+
+### trusted_devices  — MFA "Trust this device"
+
+Lets a browser/app **skip the TOTP step** at login (never the password) for 30 days. Pattern-identical
+to `mobile_refresh_tokens`: the opaque trust token lives client-side (the `rg_trust` httpOnly cookie on
+web, `X-Trust-Token` / EncryptedSharedPreferences on native) and only its **sha256** hash is stored
+(`token_hash CHAR(64) UNIQUE`) — sha256, not bcrypt, because a 256-bit random token is looked up **by
+its hash** via the unique index (a per-row salt would break that). Columns mirror the mobile table
+(`platform`, `device_name`, `device_hash`, `user_agent`, `created_at`, `last_used_at`, `expires_at`,
+`revoked_at`). Capped at 10 rows/user **in application code — no silent pruning** (an over-cap trust is
+refused so the client can prompt the user to revoke one first). Consulted only at the login/password
+step, never at token refresh, and revoked wholesale on untrust / password change / password reset /
+TOTP disable. See `docs/website/TRUSTED_DEVICES_MFA.md`.
+
+### recovery_codes  — single-use MFA backup codes
+
+Generated at TOTP enrollment (10 at a time, shown to the user **once**) so a user who loses their
+authenticator can complete login without an admin reset. `code_hash VARCHAR(72)` is a **bcrypt** hash
+(not sha256): a recovery code is a human-typed, lower-entropy fallback credential — the closest
+analogue to a password — and there is no hash-lookup constraint (verification fetches the user's ≤10
+unused rows and `bcrypt.compare`s each, like password verification). `used_at` is the single-use
+marker. Cleared wholesale on TOTP disable / password change / password reset.

-No public `register`. First admin is bootstrapped by `seed.js` from env (see §6). Further
-admins are created under `/admin/users`.
+**Role-agnostic self-service (`/auth/me/*`).** The canonical "me" surface for **every** authenticated
+role. It reuses the exact `account.controller` handlers as `/player/account/*` and `/admin/account/*`
+(no logic duplication) behind `requireAuth` **only** — any active account, never a specific role. This
+lets a client (the Android app) manage its own account through one surface without ever touching
+`/admin` (docs/android/PLAN.md §6.4). The older `/player/account/*` + `/admin/account/*` routes stay
+for web back-compat.
+
+**Password reset.** Uses the same audited pattern as `user_invites`: an opaque 32-byte token
+whose **sha256 hash only** is stored in `password_resets`, single-use and short-lived (~1h). It
+also serves SSO-only accounts (null `password_hash`) as their "set an initial password" path. The
+reset link points at the web front end (`/account/reset/:token`); the Android app hands off here
+rather than shipping its own reset screen (docs/android/PLAN.md §4.2). First admin is bootstrapped
+by `seed.js` from env (see §6); further staff are created under `/admin/users` or via email invites.
+
+**Push notifications (M7, opt-in).** The app subscribes per stream (`/auth/me/notifications/*`) and
+registers device endpoints (`/auth/me/devices`); nothing is pushed unless subscribed. Delivery is a
+**content-free tickle** — `{ stream, ref }`, no sensitive data — POSTed to each subscribed device's
+self-hosted **ntfy** endpoint (`utils/pushDispatch`); the app wakes and pulls the real, ownership-
+checked content over the authenticated API. Two producers fan out through the one publisher: the shard
+ingest dispatcher (`utils/shardIngest`, beside the SSE broadcast) for shard-derived streams, and the
+create/publish-post path for `news.post`. The stream catalog + event→stream mapping is
+`config/notificationStreams.js`. Security invariants:
+- **Same public/admin split as the SSE feed.** Public streams are drawn *only* from the SSE
+  `PUBLIC_KINDS` allowlist; a sensitive kind (audit/cheat/IP/login-attempt) can never produce a public
+  push.
+- **Personal streams are owner-keyed.** `vendor.sale` / `house.idoc` / `account.login` are delivered
+  only to the *owning* user's devices, resolved via `shardLinks` (the same ownership check as
+  `/player/shard/*`).
+- **SSRF guard.** A device `endpoint` is a client-supplied URL the server POSTs to, so registration and
+  every publish validate it is HTTPS, non-private/loopback, and (when configured) on the shard's ntfy
+  allow-set (`NTFY_BASE_URL` / `NTFY_ALLOWED_ORIGINS`).
+- ntfy is treated as an **untrusted relay** — no per-user accounts, unguessable topics; an optional
+  `NTFY_PUBLISH_TOKEN` hardens backend→ntfy publishes but is not required. See docs/android/PLAN.md §11.
+
+### Mobile SSO Authorization Bridge (`/auth/mobile/sso/*`, M9)
+
+Native "Sign in with Google/Discord" for the Android app **without shipping any OAuth secret in the
+app**. The website stays the identity authority: each shard owner's provider credentials live in
+`auth_providers` (encrypted at rest) and are only ever used server-side. The bridge is a **new
+consumer of the existing SSO + mobile-bearer machinery**, not a parallel auth path — it reuses the
+`/auth/sso/:provider/*` redirect flow, the link-only + opt-in-provisioning policy, the TOTP gate, and
+issues the **same** token pair as `/auth/mobile/login`.
+
+| Method | Path | Auth | Body / Query | Purpose |
+|---|---|---|---|---|
+| GET | `/auth/providers` | — | — | **reused** discovery; the app renders provider buttons from this (never exposes secrets) |
+| GET | `/auth/mobile/sso/start` | — (rate-limited per-IP + per-provider) | `?provider&code_challenge&state&redirect_uri` | validate provider enabled + `redirect_uri` **exact-match** allowlist; insert a `mobile_auth_sessions` row; create the existing `sso_tx` tagged `mode:'mobile'` carrying `session_id`; **302 to the IdP** (existing authorize URL) |
+| GET | `/auth/sso/:provider/callback` | — (signed `sso_tx`) | `?code&state` | **existing** endpoint; a new branch when `tx.mode==='mobile'`: resolve the account (same policy as web login incl. TOTP), mint a single-use hashed authorization code into `mobile_auth_codes`, mark the session `completed`, and **302 to `redirect_uri?code=…&state=…`** (the app's original `state`) — **no cookie is set** |
+| POST | `/auth/mobile/sso/exchange` | — (rate-limited per-IP) | `{code, code_verifier}` | validate the code exists / unexpired / unused (mark used) and `sha256(code_verifier)` matches the stored challenge → issue the existing mobile access + refresh pair (`createMobileSession`) → `{accessToken, refreshToken, expiresIn, user}` |
+| POST | `/auth/mobile/refresh` | — | `{refreshToken}` | **reused** unchanged — rotate the pair |
+| POST | `/auth/mobile/logout` | bearer | `{refreshToken?, all?}` | **reused** unchanged — revoke this (or all) refresh token(s) |
+| GET | `/auth/me/sessions` · DELETE `…/:id` | cookie / bearer | — | list / revoke own **mobile sessions** (device_name, last_used_at, created_at) — the "Active Devices" surface (distinct from `/auth/me/devices`, which is push endpoints) |
+
+**Two PKCE layers (do not conflate).**
+- *Layer A (existing):* website ↔ IdP. The `code_verifier` is generated at `/start`, kept only in the
+  httpOnly `sso_tx` cookie, sent to the IdP token endpoint at the callback. Unchanged.
+- *Layer B (new):* app ↔ website. The **app** generates `code_verifier`/`code_challenge`; the
+  challenge is stored in `mobile_auth_sessions` at `/start`; the verifier is presented at `/exchange`.
+  This is what stops an intercepted callback code from being redeemed by anyone but the real app.
+
+**State / CSRF.** The app-generated `state` is stored at `/start`, echoed on the callback redirect,
+and **verified by the app** before it calls `/exchange` — a CSRF guard independent of both PKCE
+layers (a different app instance triggering `/start` cannot complete someone else's flow).
+
+**Redirect-URI allowlist.** `/start` and the callback validate `redirect_uri` by **exact match**
+against a configured allowlist (`MOBILE_AUTH_REDIRECT_URIS`, default the one fixed application-owned
+callback `runicgateway://auth/callback`) — **never prefix match** (prefix matching on custom schemes
+is a known open-redirect vector). Tokens are **never** placed in the callback URL — only the
+short-lived authorization code.
+
+*App Links (implemented).* When the admin toggle `mobile_app_links_enabled` is **on**, `/start` also
+accepts the self-origin HTTPS callback `https://<request-host>/mobile/callback` — one *additive*
+exact-match entry, derived from the request/`APP_BASE_URL` and never from client input; the
+custom-scheme allowlist is never narrowed. The shard then auto-serves `GET
+/.well-known/assetlinks.json` (fixed package `com.runicgateway.app` + `MOBILE_APP_CERT_SHA256`
+fingerprints; 404 when the toggle is off or no fingerprint is configured), and
+`settings.getPublic()` advertises `mobileAppLinks: <bool>`. These two things — one static file route
+and one more allowlist entry — are the *entire* server surface App Links require. See
+docs/android/APP_LINKS.md.
+
+**TOTP through the bridge.** A 2FA account keeps full parity: the callback stages the existing
+pending-TOTP cookie (now also carrying the bridge `session_id`) and bounces the Custom Tab through the
+web TOTP form; on a correct code the completion mints the authorization code and deep-links back to
+the app — it never mints a session cookie for a mobile flow.
+
+**Revocation latency (documented tradeoff).** Revoking a refresh token (device revoke / logout) stops
+future renewals but does **not** invalidate an already-issued access token until it expires — up to
+the access-token lifetime (`MOBILE_ACCESS_TTL`, default 15 min) of continued access. This is an
+accepted tradeoff given the short lifetime. If instant revocation is ever required, add an
+access-token (jti) blocklist check on the `requireAuth` path — the same `revoked_sessions` mechanism
+web sessions already use.
+
+**Authorization code.** Cryptographically random, ≥128 bits, stored **hash-only**, single-use, short
+expiry (~5 min); `/exchange` is rate-limited per-IP. The bridge tables self-prune (§3).

It is a server-side, per-row-revocable record (never a JWT claim), so the stateless session JWT is unchanged and trust stays revocable.

+# Runic Gateway Website — Moderation Appeals (Phase 6c/6d)
+
+> Website feature branch: **`feature/moderation-appeals`**. Builds on the moderation
+> dashboard (Phase 6a/6b) and the Discord bot's `mod_actions` log. Companion to
+> [website-README.md](website-README.md) (overview) and
+> [BACKEND_DESIGN.md](BACKEND_DESIGN.md) (base API contract).
+
+## 1. Overview
+
+A player whose linked Discord identity was **banned** or **muted** — an action
+recorded in the bot's `mod_actions` log — can open an **appeal** from the player
+portal and track its status. Staff (**admin** or **moderator** role) work the
+appeal from an **appeals queue** in the admin moderation section: claim it, then
+resolve it **approved** or **denied** with a written staff response.
+
+When staff **approve** a ban/mute appeal, the website makes a best-effort call to
+the Discord bot's internal API to actually lift the ban / clear the timeout in
+Discord, and the bot posts a mod-log embed ("Appeal approved"). This is
+**best-effort**: if the bot is unreachable the appeal still resolves as approved,
+the reversal is recorded as failed, and staff can reverse the sanction manually in
+Discord.
+
+Only **ban** and **mute** actions are appealable — the sanctions that have an
+ongoing effect. Warnings/kicks and similar one-shot actions are not.
+
+## 2. Ownership & eligibility
+
+- **`appeals` is a server-owned table** — only the website reads/writes it. It
+  references the bot-owned `mod_actions` log by a plain id column
+  (`mod_action_id`); there is **no hard cross-owner foreign key** between the two
+  databases, so the reference is validated in application code (same pattern as
+  the rest of the uo-link / bot integration, where the two services never share a
+  live FK).
+- **Eligibility** — the appellant must be a **logged-in player** whose linked
+  Discord identity (`user_identities`, `provider = 'discord'`) matches the
+  `mod_actions` row's target. A player cannot open an appeal for someone else's
+  action, and an unlinked player has nothing eligible to appeal.
+- **One active appeal per action** — only one `pending` / `under_review` appeal is
+  allowed for a given `mod_action_id` at a time; a second attempt while one is
+  already open is rejected.
+
+## 3. Appeal lifecycle
+
+```
+pending ──▶ under_review ──▶ approved
+                          └─▶ denied
+
+pending ──▶ withdrawn
+under_review ──▶ withdrawn
+```
+
+- **`pending`** — submitted by the player, not yet claimed.
+- **`under_review`** — claimed by a staffer (the claiming admin/moderator is
+  stamped on the row).
+- **`approved`** / **`denied`** — resolved by staff with an optional
+  `staff_response`. Approving a ban/mute appeal triggers the Phase 6d reversal
+  (§5).
+- **`withdrawn`** — the player pulled the appeal back before it was resolved.
+
+`reversal_status` (only meaningful on an approved ban/mute appeal) is one of
+`none` (not attempted / not applicable), `done`, or `failed`. No new
+`mod_actions` row is written for a reversal — it modifies the *original* action's
+standing rather than logging a new one.
+
+## 4. API — player (role: `player`)
+
+Base `/api/v1/player/appeals`.
+
+| Method | Path | Purpose |
+|---|---|---|
+| GET | `/player/appeals` | The caller's own appeals. |
+| GET | `/player/appeals/eligible` | The caller's ban/mute actions with no active appeal (empty if they have no linked Discord identity). |
+| POST | `/player/appeals` | Open an appeal — `{ mod_action_id, submitted_text }`. `403` if the action isn't the caller's, `400` if the action isn't a ban/mute, `409` if one is already open for it. |
+| POST | `/player/appeals/:id/withdraw` | Withdraw an appeal that hasn't been resolved yet. |
+
+## 5. API — staff (role: `admin` or `moderator`)
+
+Base `/api/v1/admin/moderation/appeals`, alongside the existing moderation
+section.
+
+| Method | Path | Purpose |
+|---|---|---|
+| GET | `/admin/moderation/appeals?status=&limit=&offset=` | The queue. Defaults to `pending` + `under_review`; pass `status=all` or a specific status to filter. |
+| GET | `/admin/moderation/appeals/:id` | One appeal. |
+| POST | `/admin/moderation/appeals/:id/claim` | `pending` → `under_review`, stamping the claiming staffer. |
+| POST | `/admin/moderation/appeals/:id/resolve` | `{ status: 'approved' \| 'denied', staff_response? }`. On an approved ban/mute, triggers the Discord reversal (§6). |
+| GET | `/admin/moderation/user/:discordId/appeals` | A user's appeals — shown as a tab on the per-user moderation history page. |
+
+`resolve` returns a `reversal` object describing what happened:
+
+```jsonc
+{
+  "reversal": {
+    "attempted": true,
+    "ok": true,
+    "reversal_status": "done",   // "none" | "done" | "failed"
+    "bot_status": 200,
+    "error": null
+  }
+}
+```
+
+## 6. Auto-reversal (Phase 6d)
+
+On `resolve` with `status: 'approved'` against a ban/mute appeal, the website
+calls the Discord bot's internal API:
+
+```
+POST /internal/mod-reverse
+```
+
+— gated by the same shared-secret scheme as the existing `/internal/announce`
+call. The bot lifts the ban / clears the timeout for the target and posts an
+"Appeal approved" embed to its mod log.
+
+The call is **best-effort**: the appeal resolution itself always completes
+(the appeal is marked `approved` and the staff response is saved) regardless of
+whether the bot answers. If the bot is down or the call otherwise fails,
+`reversal_status` is recorded as `failed` and staff are expected to reverse the
+sanction by hand in Discord; the `reversal` object in the `resolve` response
+surfaces `ok: false` and an `error` so the UI can flag it. Denied appeals never
+attempt a reversal.
+

+in the wider site, and [BACKEND_DESIGN.md](BACKEND_DESIGN.md) for the base API

+# Trusted Devices & MFA Improvements — Design & Implementation Plan
+
+> Reference plan for the trusted-device + MFA hardening work. Approved 2026-07-21.
+> This document is the contract the implementation builds against; keep it in sync
+> with `BACKEND_DESIGN.md` (§3 schema, §4 API, §6 security) as code lands.
+
+## 1. Goal & scope
+
+Reduce 2FA friction without weakening the second-factor boundary, and close the
+2FA-lockout gap. Four deliverables:
+
+1. **Trusted devices** — an opt-in "Trust this device" that lets a browser or the
+   Android app **skip the TOTP step** (never the password) on future logins for a
+   fixed window.
+2. **Recovery / backup codes** — single-use codes generated at 2FA enrollment so a
+   user who loses their authenticator can self-recover instead of needing an admin
+   reset.
+3. **Admin-managed revocation** — staff can view and revoke a user's trusted
+   devices and reset their MFA, with full audit logging (**backend endpoints _and_
+   admin front-end screens**).
+4. **Step-up (password) for sensitive operations** — reusing the existing
+   `currentPassword`-verification pattern; disabling TOTP keeps its stronger
+   current-TOTP-code requirement.
+
+Touches `website/` (server + client), `docs/`, and `android-app/` (plan only in
+this pass). **No** `link/` or `servuo-plugins/` change — no wire-protocol impact.
+
+### Approved decisions
+
+| Decision | Value |
+|---|---|
+| Trust duration | **30 days** (matches mobile refresh-token lifetime) |
+| Roles eligible | **All roles** (no staff carve-out) |
+| Opt-in model | **Explicit "Trust this device" checkbox, default off** |
+| Recovery codes | **10 codes**, shown **once**, single-use |
+| Trusted-device cap | **10 per user, no silent pruning** (see §5) |
+| Trust-token hashing | **sha256** |
+| Recovery-code hashing | **bcrypt** (cost 10) |
+
+## 2. Current state (starting point)
+
+- **One session service** (`server/src/auth/session.service.js`) backs web (JWT
+  `httpOnly` cookie, 1d) and mobile (15m access JWT + 30d opaque refresh token).
+  `requireAuth` accepts either via `token.extractToken()`.
+- **TOTP** is opt-in per user (`users.totp_secret` / `totp_enabled`), demanded on
+  **every** login. Web uses a staged 5-min `stage:'totp'` challenge; mobile uses a
+  single-request `401 { totpRequired }`. **No recovery codes** exist today.
+- **Device tracking exists only on mobile** (`mobile_refresh_tokens` rows with
+  `device_name` / `device_hash` / `user_agent` / `last_used_at`). Web JWTs are
+  stateless with no per-session row.
+- **Revocation is mature:** `revoked_sessions` (jti denylist) + `tokens_valid_after`
+  (per-user cutoff) for web; per-token rows + `revokeAllForUser` for mobile.
+- **No trusted-device or step-up concept exists anywhere.**
+
+## 3. Hashing rationale
+
+The repo already splits hashing by secret entropy, and this plan follows it:
+
+- **sha256** — every high-entropy machine-generated opaque token
+  (`mobile_refresh_tokens`, `mobile_auth_codes`, `user_invites`, `password_resets`,
+  SSO PKCE). **Trusted-device tokens use sha256:** they are 256-bit random values
+  (nothing to brute-force) looked up **by a `token_hash UNIQUE` index**, which
+  requires a deterministic hash — bcrypt's per-row salt would break the lookup and
+  truncates input at 72 bytes.
+- **bcrypt (`bcryptjs`, cost 10)** — the repo uses it only for **passwords**, the
+  one human-chosen low-entropy secret. **Recovery codes use bcrypt:** they are a
+  human-typed, lower-entropy fallback credential that grants a login (the closest
+  analogue to a password), and there is no hash-lookup constraint — we fetch the
+  identified user's ≤10 code rows and `bcrypt.compare` each, exactly like password
+  verification.
+
+## 4. Database (additive, idempotent — matches `schema.sql` style)
+
+### `trusted_devices`
+Pattern-identical to `mobile_refresh_tokens`; stores only the token hash.
+
+| Column | Type | Notes |
+|---|---|---|
+| id | INT PK AUTO_INCREMENT | |
+| user_id | INT NOT NULL | FK → users, `ON DELETE CASCADE` |
+| token_hash | CHAR(64) NOT NULL UNIQUE | sha256 hex of the opaque trust token |
+| platform | ENUM('web','mobile') NOT NULL DEFAULT 'web' | |
+| device_name | VARCHAR(100) NULL | friendly label |
+| device_hash | VARCHAR(32) NULL | best-effort UA+IP, **display only** |
+| user_agent | VARCHAR(255) NULL | |
+| created_at | DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP | |
+| last_used_at | DATETIME NULL | stamped when trust is honored at login |
+| expires_at | DATETIME NOT NULL | created_at + 30d |
+| revoked_at | DATETIME NULL | |
+
+Indices: `idx_td_user (user_id)`, `idx_td_expires (expires_at)`.
+
+### `recovery_codes`
+| Column | Type | Notes |
+|---|---|---|
+| id | INT PK AUTO_INCREMENT | |
+| user_id | INT NOT NULL | FK → users, `ON DELETE CASCADE` |
+| code_hash | VARCHAR(72) NOT NULL | **bcrypt** hash of one code |
+| used_at | DATETIME NULL | single-use marker |
+| created_at | DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP | |
+
+Index: `idx_rc_user (user_id)`.
+
+No new `users` column: password change/reset and TOTP-disable **bulk-revoke**
+`trusted_devices` rows and **delete** `recovery_codes` (consistent with
+`revokeAllForUser`), so no "trust epoch" column is needed.
+
+## 5. Trusted-device cap — no silent pruning
+
+Cap = **10**. A shared `assertUnderTrustCap(userId)` guards both entry points (the
+login/TOTP trust path and the authenticated "trust this device" path). On the 11th
+attempt the backend **refuses to create the row** and returns
+`409 { error: 'trusted_device_limit', devices: [...] }`. Login itself still
+succeeds — only the trust marker is withheld. The web client then renders a modal
+**in the same visual pattern as the TOTP entry flow** that:
+
+1. shows the existing trusted devices,
+2. requires revoking ≥1 before continuing,
+3. completes via `POST /auth/me/trusted-devices` (trust current device), and
+4. offers **Cancel**, which returns without creating any trust entry.
+
+## 6. API additions
+
+### Auth (login paths)
+- `POST /auth/login` — after password verify, if a valid unrevoked `rg_trust`
+  cookie matches a live `trusted_devices` row for this user → **skip TOTP**, issue
+  the session, log `auth.login.trusted_device`, stamp `last_used_at`. Otherwise
+  unchanged (`{ totpRequired, challenge }`).
+- `POST /auth/login/totp` — gains optional `trustDevice` + `deviceName`, and
+  accepts a **recovery code** as an alternative to the TOTP code (single-use). On
+  success with `trustDevice`, mint the opaque trust token, set the `rg_trust`
+  cookie, insert the row (subject to the cap → `409` signal).
+- `POST /auth/mobile/login` — gains `trustDevice` / `recoveryCode`; returns a
+  `trustToken` the app stores in EncryptedSharedPreferences and replays on a later
+  login to skip TOTP. Same cap behavior.
+
+### Self-service (`/auth/me/*`, `requireAuth`, any role)
+- `GET /auth/me/trusted-devices` — list active trusted devices (never tokens).
+- `POST /auth/me/trusted-devices` — trust the current browser/device (cap-checked).
+- `DELETE /auth/me/trusted-devices/:id` — revoke one (ownership-scoped).
+- `DELETE /auth/me/trusted-devices` — revoke all ("untrust everywhere").
+- `POST /auth/me/account/recovery-codes/generate` — **password step-up required**;
+  returns the codes **once**.
+- `GET /auth/me/account/recovery-codes/status` — remaining count only.
+
+### Admin (`requireRole('admin')`)
+- `GET /admin/users/:id/trusted-devices` — list a user's trusted devices.
+- `DELETE /admin/users/:id/trusted-devices/:deviceId` — revoke one.
+- `DELETE /admin/users/:id/trusted-devices` — revoke all.
+- MFA reset control (revoke trust + disable TOTP + clear recovery codes).
+
+## 7. Cookie / refresh / JWT interaction
+
+- New **`rg_trust`** cookie: `httpOnly`, `sameSite=Lax`, `secure` per-request
+  (reuse `cookieSecure`), `path=/`, `maxAge` 30d, opaque 256-bit base64url,
+  sha256-hashed server-side. **Separate from the session cookie and deliberately
+  survives logout** (so the next login skips 2FA); only untrust / password-change /
+  TOTP-disable revoke it.
+- **JWTs stay stateless and unchanged** — trust is a server-side cookie+row, never
+  a JWT claim, so it remains revocable.
+- **Refresh flow untouched** — trust is consulted only at the login/password step,
+  never at token refresh; the two stores stay independent.
+
+## 8. Security & invalidation
+
+- Trust **only ever gates the second factor**; password is always required.
+- Recovery-code entry reuses the login brute-force stack (backoff + bot scoring +
+  rate limits); recovery codes are single-use.
+- **Password change/reset and TOTP-disable clear trust and recovery codes.**
+- **Audit logging** via existing `activity.log` / `activity_log`:
+  `auth.login.trusted_device`, `account.trusted_device.add` / `.revoke` /
+  `.revoke_all`, `account.recovery_codes.generate`, `account.recovery_code.consume`,
+  and admin `admin.trusted_device.revoke` / `.revoke_all`, `admin.user.totp.reset`
+  — each with actor, target user, and device id in `detail`.
+
+## 9. Backwards compatibility
+
+Fully additive. With no `rg_trust` cookie the behavior is exactly today's (TOTP
+every login). Recovery codes exist only for users who generate them. No existing
+session or login flow changes shape. New tables via `CREATE TABLE IF NOT EXISTS`
+and columns via `ALTER TABLE … ADD COLUMN IF NOT EXISTS`.
+
+## 10. Implementation roadmap
+
+1. **Schema + models** — `trusted_devices` (sha256, cap-checked) + `recovery_codes`
+   (bcrypt); `.db.js` / `.model.js` pairs mirroring `mobileSessions`.
+2. **Session service** — trust-token mint/sha256/verify + recovery-code
+   generate/bcrypt-verify/consume helpers (pure, DB-free); shared
+   `assertUnderTrustCap()`.
+3. **Web login** — trust-cookie skip in `/auth/login`; `trustDevice` / recovery
+   handling + cap `409` in `/auth/login/totp`; set/clear `rg_trust`.
+4. **Mobile login** — `trustDevice` / `trustToken` / `recoveryCode`, same cap.
+5. **Self-service + admin backend** — `/auth/me/trusted-devices*` + recovery-code
+   endpoints; `/admin/users/:id/trusted-devices*` + MFA reset (all admin-gated).
+6. **Invalidation wiring** — password change/reset & TOTP-disable revoke trust +
+   delete recovery codes.
+7. **Web client UI** — "Trust this device" checkbox; cap-reached TOTP-styled modal
+   (revoke-to-continue / cancel); user Trusted Devices + Recovery Codes screens.
+8. **Admin front-end UI** — admin Trusted Devices management & revocation screens
+   (per-user list, revoke one / revoke all, MFA reset), wired to step 5.
+9. **Android** — record the app-side trust/recovery flow in
+   `docs/android/PLAN.md`; app implementation sequenced after the backend lands.
+10. **OpenAPI + docs** — `#swagger.*` on every new/modified route + regenerate
+    `server/swagger/swagger-output.json`; update `BACKEND_DESIGN.md` §3/§4/§6.
+11. **Automated tests** — trusted-device login skip (valid / missing / expired /
+    revoked), token mint+hash, recovery-code single-use consume + wrong-code
+    backoff, cap `409` behavior, revocation (self + admin), invalidation on
+    password-change / TOTP-disable, and permission checks (admin routes reject
+    non-admins; self routes ownership-scoped); web client pure-logic tests; Android
+    JVM DTO/repository tests.

+# Runic Gateway Website — Test Plan (Discord bot)
+
+> Companion to [website-README.md](website-README.md) (overview) and
+> [BACKEND_DESIGN.md](BACKEND_DESIGN.md) (server API/schema/security contract).
+> Establishes the test plan for the **`bot/` workspace** (the Discord bot), the
+> last of the three `website` npm workspaces without a suite. The server and
+> client suites already exist (website PR #86); this doc closes the bot gap and
+> records the shared conventions so all three stay consistent.
+
+## 1. Goal & philosophy
+
+Cover **meaningful bot behavior** — the moderation/filter decisions a future
+change could silently break — not a coverage number. The bot's value is in *what
+it decides to delete, warn, mute, or let through*; a good test reads "given this
+message + config, what action does the bot take?", never "did this function call
+that function?".
+
+The whole `website` repo tests on **Node's built-in runner (`node --test`)** with
+**zero external test dependencies** — no jest, no vitest, no jsdom. Unit tests
+run without a database or a live Discord gateway: the DB pool is pointed at a dead
+port and every collaborator (`db.query`, a model, a Discord `message`/`client`) is
+replaced with an in-memory fake. This mirrors the server suite exactly (the bot is
+CommonJS, like the server — `require`/`module.exports` — so the same patterns
+apply verbatim).
+
+## 2. Current state
+
+| Workspace | Runner | Status |
+|---|---|---|
+| `server/` | `node --test` | **Exists** — models, controllers, auth/session, shard ingest. |
+| `client/` | `node --test` (pure-logic ESM) | **Exists** (PR #86) — `lib/`, `api/`, `data/`. |
+| `bot/` | — | **This plan** — no runner or tests yet. |
+
+The 46% SonarQube aggregate is dragged down by the bot (and the client's
+un-unit-testable React components) reading as 0% covered. Standing up the bot
+suite lifts the real number and, more importantly, locks the filter/moderation
+rules.
+
+## 3. Harness
+
+Add a test script to `bot/package.json` (mirrors server/client):
+
+```json
+"scripts": { "test": "node --test" }
+```
+
+Conventions, identical to `server/test/`:
+
+- **No DB.** Set `process.env.DB_HOST = '127.0.0.1'` / `DB_PORT = '59999'` at the
+  top of any test whose module transitively `require`s `../db`, so the pool is
+  built against a dead port and a stray query fails fast instead of hanging.
+  Models are exercised by monkeypatching `db.query` (or the model method the unit
+  under test calls) with an in-memory fake; restore it in `afterEach`.
+- **No Discord.** The `discord.js` `Client`, `Message`, `GuildMember`, and
+  `Interaction` objects are hand-rolled fakes carrying only the fields the unit
+  reads (e.g. `message.mentions.users.size`, `message.member.roles.cache`,
+  `message.client.fetchInvite`). Never construct a real client or open a gateway
+  connection.
+- **Tests live in `bot/test/*.test.js`.** One file per module under test.
+
+## 4. Units to cover
+
+Ordered high-value first. Each row names the module, the behavior worth locking,
+and the seam a test drives it through.
+
+### 4.1 Pure logic (no mocks beyond inputs)
+
+| Module | Behaviors to lock | Notes |
+|---|---|---|
+| `filter/normalize.js` | leetspeak folding (`b4d`→`bad`, `@ss`→`ass`), 3+-repeat collapse (`sooooo`→`so`), case-fold; `matches()` is word-boundary anchored (so `bad` does not fire inside `badminton`); `findMatch()` returns the first `{word, severity}` row or `null`; the *documented gaps* stay gaps (spaced-out `b a d` is **not** caught). | The core obfuscation-resistance contract. Pin the gaps too, so a future tightening is a deliberate, test-visible change. |
+| `utils/duration.js` | `"30s"/"10m"/"2h"/"1d"` → correct ms; whitespace tolerated; garbage/empty/unknown-unit → `null`; `MAX_TIMEOUT_MS` is 28 days (the Discord cap callers clamp to). | Feeds `/mute` and temp-role expiry — a wrong parse mutes for the wrong span. |
+| `filter/spamFilter.js` | `isRateLimited` trips on the 6th message inside the 5 s window and is per-`guild:user`; it has a **side effect** (records the timestamp) so it must be called once; `isMassMention` counts users **+** roles against the threshold; `isMassEmoji` counts custom `<:name:id>` and unicode pictographs. | Drive time with a stubbed `Date.now` (or accept the real clock and use tight windows). The module-load `setInterval(...).unref()` sweep must not keep the runner alive — `.unref()` already handles this; assert no leak by letting the suite exit. |
+
+### 4.2 Logic with a single mocked collaborator
+
+| Module | Behaviors to lock | Seam / mock |
+|---|---|---|
+| `filter/inviteFilter.js` | returns the **code** (not a bool) of the first *foreign* invite; an invite resolving to the current guild is allowed; an invite that **fails to resolve** (expired/invalid) is treated as foreign (fail-closed); no invite in the message → `null`. | Fake `message.client.fetchInvite(code)` — resolve with `{ guild: { id } }` for local/foreign, or throw for unresolvable. Set `message.guildId` + `message.content`. |
+| `site/siteApiClient.js` | never throws on a network/timeout/HTTP failure — always returns the `{ ok, ... }` shape so a command never breaks when the site is down: `{ ok: true, data }` on success, `{ ok: false, error }` on failure, and the distinct `{ ok: false, maintenance: true, message }` for the site's 503 maintenance response. (Public read client — **no** shared secret; the keyed channel is `botInternalClient.js`.) | Stub `global.fetch` (resolve various statuses/bodies, reject/timeout via `AbortController`). Same non-throwing contract the server's `uoLinkClient` follows. |
+| `internal/requireInternalKey.js` | `401` on a missing/wrong key; `next()` on the configured key; **fail-closed** when `BOT_INTERNAL_KEY` is empty (never matches); timing-safe compare (equal-length + `crypto.timingSafeEqual`, no early-exit length leak). | Call the middleware with a fake `req` (`req.get('X-Internal-Key')`) + `res`/`next` spies; mirrors `server/test/requireInternalKey.test.js`. |
+
+### 4.3 The filter pipeline (orchestration)
+
+`discord/messageFilter.js` is the highest-value integration seam — it composes
+all of §4.1–4.2. Lock the **decision order and the actions**, with every
+collaborator faked:
+
+- **Bypass wins first:** an allow-listed channel, or a member holding an
+  allow-listed role, short-circuits the whole pipeline (`isBypassed`) — no
+  delete, no hit recorded.
+- **Order:** invite link → banned word → spam (rate-limit → mass-mention →
+  mass-emoji). `detectSpam` must evaluate `isRateLimited` **first and exactly
+  once** (it has the timestamp side effect).
+- **Actions:** invite/spam always delete + warn (no severity tiers); a
+  word-filter hit applies the action for its severity; filter-triggered mutes use
+  the fixed `FILTER_MUTE_SECONDS` (600 s).
+- **Best-effort recording never breaks moderation:** `recordFilterHit` /
+  `recordSpamHit` throwing must be swallowed — the delete/warn still happens.
+
+Mocks: `filterCache` (in-memory `allowChannels`/`allowRoles` Sets + words), a fake
+`message` (content, author, member roles, `delete()`, `guildId`), and spies on
+`warnings`/`filterHits`/`spamHits`/`modLog` to assert what was called.
+
+### 4.4 Models (`bot/model/*.js`)
+
+Thin `db.query` wrappers (e.g. `warnings.js`, `filterWords.js`, `filterHits.js`,
+`spamHits.js`, `memberEvents.js`, `guildConfig.js`, `scheduledMessages.js`,
+`tempRoles.js`). Cover only those with **shaping/branching logic** (a query that
+maps rows, applies an "active/not-expired" predicate, or upserts) by asserting the
+**SQL params** passed to a fake `db.query` and the shape returned. Skip pure
+one-line inserts with no logic — testing those only proves the mock.
+
+## 5. Explicitly out of scope
+
+- **`discord.js` internals / the live gateway** — not ours to test; never open a
+  real connection.
+- **Thin command wrappers** (`discord/commands/*.command.js`) that only validate
+  args and call a Discord API + a model — cover their *logic* (arg parsing,
+  duration clamping) if any, but not the Discord round-trip.
+- **`node-cron` scheduling itself** — test the job's callback logic, not that cron
+  fires.
+
+## 6. CI & coverage wiring
+
+Mirror what PR #86 did for the client:
+
+- **`.gitea/workflows/pr-checks.yml`** — add a `bot-tests` job (or a
+  `Run bot tests` step) that runs `npm test --prefix bot`, gating PRs into `main`.
+- **`.gitea/workflows/sonarqube.yml`** — generate a bot LCOV from the repo root so
+  `SF:` paths resolve to `bot/src/...`:
+
+  ```
+  node --test --experimental-test-coverage \
+    --test-reporter=lcov --test-reporter-destination=bot/coverage/lcov.info \
+    bot/test/*.test.js
+  ```
+
+- **`sonar-project.properties`** — add `bot/test` to `sonar.tests`, the glob to
+  `sonar.test.inclusions`, `bot/coverage/lcov.info` to
+  `sonar.javascript.lcov.reportPaths`, and `bot/coverage/**` to `sonar.exclusions`.
+  (`bot/src` is already in `sonar.sources`.)
+
+Bot units need no `npm ci` to run when they import only relative files + Node
+built-ins; a test that stubs `global.fetch` or fakes `db` needs no `discord.js`
+either. Keep the pool pointed at a dead port so the run is hermetic.
+
+## 7. Suggested phasing
+
+1. **Harness + pure logic** — `test` script, then `normalize`, `duration`,
+   `spamFilter`. Fast, zero mocks, immediate value.
+2. **Single-collaborator units** — `inviteFilter`, `siteApiClient`,
+   `requireInternalKey`.
+3. **Pipeline** — `messageFilter` decision order + actions (the payoff test).
+4. **Models with logic**, then the **CI/Sonar wiring** so it all counts.

 - **Shard link** — a live bridge to the in-game ServUO shard through the **uo-link** sidecar ([RunicGateway/link](https://gitea.whitlocktech.com/RunicGateway/link)): the site ingests a live event feed and makes server-side REST calls to show shard status, economy, staff presence, IDOCs, live activity, and per-character sheets.

+How the pieces fit together — the React SPA and native app talk to one Express backend
+(`router → controller → model → db`), which persists to MariaDB and bridges to the live
+game world only through the **uo-link** sidecar. The shard itself is never internet-facing.

+- **One backend, layered.** Every request flows `middleware → router → controller → model → db`.
+  Web browsers authenticate with an httpOnly JWT cookie; the native app uses short-lived bearer
+  access tokens plus rotated refresh tokens; SSO (Google/Discord/OIDC) is link-only and PKCE-guarded.
+  All three surfaces produce the *same* session via the session layer.
+- **The shard is never reachable.** The ServUO shard *dials out* over loopback TCP to the uo-link
+  sidecar; only the sidecar is exposed, and only the backend talks to it. The REST client
+  (`uoLinkClient.js`) never throws, so the site degrades gracefully when the shard is down.
+- **Sensitive events stay private.** Ingested game events fan out to browsers over two SSE channels —
+  a public allowlist stream and an admin-only stream that adds staff audit / cheat / login events.
