+# GitHub Actions Workflows
+
+This directory contains GitHub Actions workflows for automated CI/CD processes.
+
+## Workflows Overview
+
+### 🔨 `build.yml` - Build Desktop App
+**Triggers:** Push to main/develop, Pull Requests, Releases
+
+**Purpose:** Builds the desktop application for all supported platforms (macOS, Windows, Linux)
+
+**Features:**
+- Cross-platform builds (macOS Universal, Windows x64, Linux x64)
+- Automatic artifact uploads
+- Release asset publishing
+- Caching for faster builds
+
+**Artifacts:**
+- **macOS**: DMG installer and .app bundle
+- **Windows**: MSI and NSIS installers
+- **Linux**: DEB package and AppImage
+
+### 🧪 `ci.yml` - Continuous Integration
+**Triggers:** Push to main/develop, Pull Requests
+
+**Purpose:** Code quality checks and testing
+
+**Features:**
+- Frontend build verification
+- Rust formatting and linting (rustfmt, clippy)
+- Rust unit tests
+- Security audits for both frontend and backend dependencies
+
+### 🚀 `release.yml` - Manual Release
+**Triggers:** Manual workflow dispatch
+
+**Purpose:** Create tagged releases with built applications
+
+**Features:**
+- Manual version input
+- Pre-release option
+- Automatic release notes generation
+- Cross-platform builds and uploads
+- Comprehensive installation instructions
+
+**Usage:**
+1. Go to Actions tab in GitHub
+2. Select "Release" workflow
+3. Click "Run workflow"
+4. Enter version (e.g., v1.0.0)
+5. Choose if it's a pre-release
+6. Click "Run workflow"
+
+### 🔄 `dependencies.yml` - Dependency Management
+**Triggers:** Weekly schedule (Mondays 9 AM UTC), Manual dispatch
+
+**Purpose:** Automated dependency updates and security monitoring
+
+**Features:**
+- Weekly dependency updates
+- Automatic PR creation for updates
+- Security vulnerability detection
+- Automatic issue creation for security alerts
+
+## Setup Requirements
+
+### Repository Secrets
+No additional secrets are required beyond the default `GITHUB_TOKEN`.
+
+### Branch Protection (Recommended)
+Configure branch protection rules for `main` branch:
+- Require status checks to pass before merging
+- Require branches to be up to date before merging
+- Include status checks: `lint-and-test`, `security-audit`
+
+### Release Process
+
+#### Automated (Recommended)
+1. Merge changes to `main` branch
+2. Use the manual release workflow to create a new release
+3. The workflow will automatically build and upload all platform binaries
+
+#### Manual
+1. Create a new tag: `git tag v1.0.0`
+2. Push the tag: `git push origin v1.0.0`
+3. Create a release on GitHub
+4. The build workflow will automatically attach binaries
+
+## Platform-Specific Notes
+
+### macOS
+- Builds universal binaries (Intel + Apple Silicon)
+- Requires macOS 13.0 or later
+- DMG installer includes code signing (if certificates are configured)
+
+### Windows
+- Builds for x64 architecture
+- Provides both MSI and NSIS installers
+- Compatible with Windows 10 and later
+
+### Linux
+- Builds for x64 architecture
+- Provides DEB package for Debian/Ubuntu
+- Provides AppImage for universal Linux compatibility
+- Requires WebKit2GTK and other system dependencies
+
+## Troubleshooting
+
+### Build Failures
+1. Check the specific platform logs in the Actions tab
+2. Ensure all dependencies are properly declared
+3. Verify Tauri configuration is correct
+
+### Security Audit Failures
+1. Review the security report in the workflow logs
+2. Update vulnerable dependencies
+3. Consider using `pnpm audit --fix` for frontend issues
+4. Use `cargo update` for Rust dependency updates
+
+### Cache Issues
+If builds are failing due to cache corruption:
+1. Go to Actions tab
+2. Click on "Caches" in the sidebar
+3. Delete relevant caches
+4. Re-run the workflow
+
+## Customization
+
+### Adding New Platforms
+To add support for additional platforms, modify the `matrix` section in `build.yml`:
+
+```yaml
+matrix:
+  include:
+    - platform: 'macos-latest'
+      args: '--target aarch64-apple-darwin'
+      target: 'aarch64-apple-darwin'
+```
+
+### Modifying Build Steps
+Each workflow can be customized by:
+1. Adding new steps
+2. Modifying existing commands
+3. Adding environment variables
+4. Configuring different Node.js/Rust versions
+
+### Adding Code Quality Tools (Optional)
+If you want to add code quality tools in the future:
+1. **ESLint**: Add ESLint configuration and dependencies for JavaScript/TypeScript linting
+2. **Prettier**: Add Prettier for consistent code formatting
+3. **TypeScript strict checking**: Enable stricter TypeScript rules and type checking
+
+### Changing Schedule
+Modify the `cron` expression in `dependencies.yml` to change the update frequency:
+```yaml
+schedule:
+  - cron: '0 9 * * 1'  # Every Monday at 9 AM UTC
+```

+                    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.>
+    Copyright (C) <year>  <name of author>

+    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

+# LED Strip Test Device Auto-Refresh Implementation
+
+## Overview
+Implemented automatic refresh functionality for the device dropdown in the LED strip test interface. The device list now updates in real-time when devices are discovered, connected, or disconnected.
+
+## Changes Made
+
+### 1. Frontend Changes (`src/components/led-strip-test/led-strip-test.tsx`)
+
+#### Added Event Listener Import
+```typescript
+import { listen } from '@tauri-apps/api/event';
+```
+
+#### Enhanced Device Loading Logic
+- **Initial Load**: Still loads devices on component mount using `get_boards()`
+- **Real-time Updates**: Added listener for `boards_changed` events from backend
+- **Smart Selection**: Automatically handles device selection when devices are added/removed:
+  - If current device disconnects, automatically selects first available device
+  - If no device was selected and devices become available, selects the first one
+  - Properly cleans up event listeners on component unmount
+
+#### Improved UI Display
+- **Device Count**: Shows number of devices found in label
+- **Connection Status**: Each device option shows:
+  - Status icon (🟢 Connected, 🟡 Connecting, 🔴 Disconnected)
+  - Device name and address
+  - Connection status text
+- **Empty State**: Shows "Searching..." when no devices found
+
+#### Type Safety Improvements
+- Updated `BoardInfo` interface to match backend types
+- Proper handling of `connect_status` union type
+- Type-safe status checking functions
+
+### 2. Backend Integration
+The implementation leverages existing backend infrastructure:
+- **UdpRpc Manager**: Continuously searches for devices via mDNS
+- **Device Monitoring**: Checks device connectivity every second
+- **Event Broadcasting**: Sends `boards_changed` events to frontend
+- **Status Tracking**: Maintains real-time connection status for each device
+
+## Technical Details
+
+### Event Flow
+1. Backend `UdpRpc` discovers devices via mDNS service discovery
+2. Backend monitors device connectivity with periodic health checks
+3. Backend broadcasts `boards_changed` events when device list changes
+4. Frontend listens for events and updates UI automatically
+5. Frontend handles device selection logic intelligently
+
+### Connection Status Types
+- `Connected`: Device is responding to ping requests
+- `Connecting`: Device is in retry state (with retry count)
+- `Disconnected`: Device is not responding
+
+### Error Handling
+- Graceful fallback if initial device load fails
+- Proper cleanup of event listeners
+- Maintains UI state consistency during device changes
+
+## Benefits
+1. **Real-time Updates**: No need to manually refresh device list
+2. **Better UX**: Visual indicators for device status
+3. **Automatic Recovery**: Handles device disconnections gracefully
+4. **Type Safety**: Proper TypeScript types prevent runtime errors
+5. **Performance**: Efficient event-driven updates instead of polling
+
+## Implementation Status
+✅ **Completed**: LED Strip Test device dropdown auto-refresh
+✅ **Already Implemented**: Board Index page auto-refresh (was already working)
+✅ **Type Safety**: Fixed TypeScript type definitions for BoardInfo
+✅ **UI Improvements**: Added status indicators and device count display
+
+## Testing
+To test the functionality:
+1. Start the application with `npm run tauri dev`
+2. Navigate to LED Strip Test page
+3. Observe device list updates as devices come online/offline
+4. Verify status indicators show correct connection states:
+   - 🟢 Connected devices
+   - 🟡 Connecting devices (with retry count)
+   - 🔴 Disconnected devices
+5. Test device selection behavior when devices disconnect
+6. Check that device count is displayed in the label
+
+## Code Quality
+- ✅ No TypeScript errors
+- ✅ Proper event listener cleanup
+- ✅ Type-safe status checking
+- ✅ Consistent with existing codebase patterns
+- ✅ Follows SolidJS best practices
+
+## Future Enhancements
+- Add device refresh button for manual refresh
+- Show device discovery progress indicator
+- Add device connection retry controls
+- Display device ping latency information
+- Add device connection history/logs

+# LED Hardware Communication Protocol
+
+## Overview
+
+UDP-based bidirectional protocol for communication between desktop application and ambient light hardware boards. The protocol supports LED color data transmission, device health monitoring, and remote control capabilities.
+
+## Connection
+
+- **Protocol**: UDP
+- **Port**: 23042
+- **Discovery**: mDNS (`_ambient_light._udp.local.`)
+- **Example Board**: `192.168.31.206:23042`
+
+## mDNS Service Discovery
+
+### Service Registration (Hardware Side)
+
+Hardware boards must register the following mDNS service:
+
+- **Service Type**: `_ambient_light._udp.local.`
+- **Port**: 23042
+- **TXT Records**: Optional, can include device information
+
+### Service Discovery (Desktop Side)
+
+Desktop application continuously browses for `_ambient_light._udp.local.` services and automatically connects to discovered devices.
+
+## Protocol Messages
+
+The protocol uses different message headers to distinguish message types:
+
+| Header | Direction | Purpose | Format |
+|--------|-----------|---------|---------|
+| 0x01 | Desktop → Hardware | Ping (Health Check) | `[0x01]` |
+| 0x01 | Hardware → Desktop | Pong (Health Response) | `[0x01]` |
+| 0x02 | Desktop → Hardware | LED Color Data | `[0x02][Offset_H][Offset_L][Color_Data...]` |
+| 0x03 | Hardware → Desktop | Display Brightness Control | `[0x03][Display_Index][Brightness]` |
+| 0x04 | Hardware → Desktop | Volume Control | `[0x04][Volume_Percent]` |
+
+## Health Check Protocol (Ping/Pong)
+
+### Desktop → Hardware (Ping)
+
+```text
+Byte 0: Header (0x01)
+```
+
+### Hardware → Desktop (Pong)
+
+```text
+Byte 0: Header (0x01)
+```
+
+**Behavior:**
+
+- Desktop sends ping every 1 second to each connected device
+- Hardware must respond with pong within 1 second
+- Timeout or incorrect response triggers reconnection logic
+- After 10 failed attempts, device is marked as disconnected
+
+## LED Color Data Protocol
+
+### Packet Format
+
+```text
+Byte 0: Header (0x02)
+Byte 1: Offset High (upper 8 bits of data byte offset)
+Byte 2: Offset Low (lower 8 bits of data byte offset)
+Byte 3+: LED Color Data (variable length)
+```
+
+## LED Color Data
+
+### RGB LEDs (3 bytes per LED)
+
+```text
+[R][G][B][R][G][B][R][G][B]...
+```
+
+### RGBW LEDs (4 bytes per LED)
+
+```text
+[R][G][B][W][R][G][B][W][R][G][B][W]...
+```
+
+All values are 0-255.
+
+### Offset Calculation
+
+The offset field specifies the starting byte position in the LED data buffer:
+
+- **16-bit value**: Combines Offset High and Offset Low bytes (big-endian)
+- **Range**: 0-65535 bytes supported
+- **Purpose**: Allows partial updates of LED strip data at any byte position
+
+**Example Calculations:**
+
+- Byte position 0: `Offset High = 0x00, Offset Low = 0x00`
+- Byte position 30: `Offset High = 0x00, Offset Low = 0x1E` (10 RGB LEDs × 3 bytes)
+- Byte position 256: `Offset High = 0x01, Offset Low = 0x00`
+- Byte position 1000: `Offset High = 0x03, Offset Low = 0xE8`
+
+**LED Position to Byte Offset Conversion:**
+
+- **RGB LEDs**: `byte_offset = led_position × 3`
+- **RGBW LEDs**: `byte_offset = led_position × 4`
+
+## LED Chip Specifications
+
+### WS2812B (RGB)
+
+- **Type**: RGB
+- **Data Format**: 3 bytes per LED
+- **Color Order**: G-R-B (Green, Red, Blue)
+- **Voltage**: 5V
+- **Protocol**: Single-wire serial
+- **Timing**: 800kHz data rate
+
+### SK6812 (RGB)
+
+- **Type**: RGB
+- **Data Format**: 3 bytes per LED
+- **Color Order**: G-R-B (Green, Red, Blue)
+- **Voltage**: 5V
+- **Protocol**: Single-wire serial
+- **Timing**: 800kHz data rate
+- **Features**: Improved PWM linearity compared to WS2812B
+
+### SK6812-RGBW
+
+- **Type**: RGBW
+- **Data Format**: 4 bytes per LED
+- **Color Order**: G-R-B-W (Green, Red, Blue, White)
+- **Voltage**: 5V
+- **Protocol**: Single-wire serial
+- **Timing**: 800kHz data rate
+- **Features**: Dedicated white channel for better color mixing and higher brightness
+
+## Color Calibration
+
+Colors are calibrated before transmission:
+
+**RGB:**
+
+```rust
+calibrated_r = (original_r * calibration_r) / 255
+calibrated_g = (original_g * calibration_g) / 255  
+calibrated_b = (original_b * calibration_b) / 255
+```
+
+**RGBW:**
+
+```rust
+calibrated_r = (original_r * calibration_r) / 255
+calibrated_g = (original_g * calibration_g) / 255
+calibrated_b = (original_b * calibration_b) / 255
+calibrated_w = calibration_w  // Direct value
+```
+
+## Hardware Control Protocol (Hardware → Desktop)
+
+### Display Brightness Control
+
+Hardware can send display brightness adjustment commands to the desktop:
+
+```text
+Byte 0: Header (0x03)
+Byte 1: Display Index (0-based display number)
+Byte 2: Brightness (0-255, where 255 = 100% brightness)
+```
+
+**Example:** Set display 0 to 50% brightness
+
+```text
+03 00 80
+│  │  └─ Brightness (128 = ~50%)
+│  └─ Display Index (0)
+└─ Header (0x03)
+```
+
+### Volume Control
+
+Hardware can send system volume adjustment commands to the desktop:
+
+```text
+Byte 0: Header (0x04)
+Byte 1: Volume Percent (0-100)
+```
+
+**Example:** Set system volume to 75%
+
+```text
+04 4B
+│  └─ Volume (75%)
+└─ Header (0x04)
+```
+
+## Connection State Management
+
+### Connection States
+
+- **Unknown**: Initial state when device is first discovered
+- **Connecting**: Device is being tested, includes retry count (1-10)
+- **Connected**: Device is responding to ping requests normally
+- **Disconnected**: Device failed to respond after 10 retry attempts
+
+### State Transitions
+
+```text
+Unknown → Connecting(1) → Connected
+    ↓           ↓             ↓
+    ↓      Connecting(2-10)   ↓
+    ↓           ↓             ↓
+    └─→ Disconnected ←────────┘
+```
+
+### Retry Logic
+
+1. **Initial Connection**: When device discovered via mDNS
+2. **Health Check Failure**: If ping timeout or wrong response
+3. **Retry Attempts**: Up to 10 attempts with 1-second intervals
+4. **Disconnection**: After 10 failed attempts, mark as disconnected
+5. **Recovery**: Disconnected devices continue to receive ping attempts
+
+## Packet Examples
+
+### RGB Example
+
+3 RGB LEDs starting at byte offset 0: Red, Green, Blue
+
+```text
+02 00 00 FF 00 00 00 FF 00 00 00 FF
+│  │  │  └─────────────────────────── 9 bytes color data
+│  │  └─ Offset Low (0 bytes)
+│  └─ Offset High (0)
+└─ Header (0x02)
+```
+
+### RGBW Example
+
+2 RGBW LEDs starting at byte offset 40 (LED position 10): White, Warm White
+
+```text
+02 00 28 FF FF FF FF FF C8 96 C8
+│  │  │  └─────────────────────── 8 bytes color data
+│  │  └─ Offset Low (40 bytes = 0x28)
+│  └─ Offset High (0)
+└─ Header (0x02)
+```
+
+## Implementation Notes
+
+- **Byte Order**: Big-endian for multi-byte values (offset field)
+- **Delivery**: Fire-and-forget UDP (no acknowledgment required)
+- **Hardware Role**: Simple UDP-to-LED bridge, no data processing
+- **LED Type Logic**: Handled entirely on desktop side, not hardware
+- **Mixed Types**: Same display can have both RGB and RGBW strips
+- **Data Flow**: Desktop → UDP → Hardware → LED Strip (direct forward)
+- **Color Order**: Hardware must handle color order conversion for different LED chips
+- **LED Compatibility**: Supports WS2812B, SK6812, and SK6812-RGBW chips
+
+## Hardware Implementation
+
+The hardware board handles multiple protocol functions: UDP-to-WS2812 bridge for LED data, health monitoring, and optional control input capabilities.
+
+### Required Functions
+
+1. **mDNS Service Registration**: Advertise `_ambient_light._udp.local.` service
+2. **UDP Server**: Listen on port 23042 for incoming packets
+3. **Packet Processing**: Handle different message types based on header
+4. **Health Monitoring**: Respond to ping requests with pong
+5. **LED Control**: Forward color data to WS2812 strips
+6. **Optional Control**: Send brightness/volume commands to desktop
+
+### Packet Processing Logic
+
+```c
+void process_packet(uint8_t* data, size_t len) {
+    if (len < 1) return;
+
+    switch (data[0]) {
+        case 0x01: // Ping request
+            handle_ping(data, len);
+            break;
+
+        case 0x02: // LED color data
+            handle_led_data(data, len);
+            break;
+
+        default:
+            // Unknown packet type, ignore
+            break;
+    }
+}
+
+void handle_ping(uint8_t* data, size_t len) {
+    if (len != 1) return;
+

+    uint8_t pong = 0x01;
+    udp_send_response(&pong, 1);
+}
+
+void handle_led_data(uint8_t* data, size_t len) {
+    if (len < 3) return;
+
+    uint16_t byte_offset = (data[1] << 8) | data[2];
+    uint8_t* color_data = &data[3];
+    size_t color_len = len - 3;
+
+    // Direct forward to LED strip - supports WS2812B, SK6812, SK6812-RGBW
+    // byte_offset specifies the starting byte position in LED data buffer
+    // Color order conversion handled by LED driver library
+    led_strip_update(byte_offset, color_data, color_len);
+}
+```
+
+### Optional Control Features
+
+Hardware can optionally send control commands to desktop:
+
+```c
+// Send display brightness control
+void send_brightness_control(uint8_t display_index, uint8_t brightness) {
+    uint8_t packet[3] = {0x03, display_index, brightness};
+    udp_send_to_desktop(packet, 3);
+}
+
+// Send volume control
+void send_volume_control(uint8_t volume_percent) {
+    uint8_t packet[2] = {0x04, volume_percent};
+    udp_send_to_desktop(packet, 2);
+}
+```
+
+### LED Strip Driver Implementation
+
+For SK6812-RGBW support, hardware must handle the G-R-B-W color order:
+
+```c
+// Example LED strip update function for SK6812-RGBW
+void led_strip_update(uint16_t offset, uint8_t* data, size_t len) {
+    // For SK6812-RGBW: data comes as [R][G][B][W] from desktop
+    // Must be reordered to [G][R][B][W] for the LED chip
+
+    size_t led_count = len / 4; // 4 bytes per RGBW LED
+    uint8_t* output_buffer = malloc(len);
+
+    for (size_t i = 0; i < led_count; i++) {
+        uint8_t r = data[i * 4 + 0];
+        uint8_t g = data[i * 4 + 1];
+        uint8_t b = data[i * 4 + 2];
+        uint8_t w = data[i * 4 + 3];
+
+        // Reorder to G-R-B-W for SK6812-RGBW
+        output_buffer[i * 4 + 0] = g; // Green first
+        output_buffer[i * 4 + 1] = r; // Red second
+        output_buffer[i * 4 + 2] = b; // Blue third
+        output_buffer[i * 4 + 3] = w; // White fourth
+    }
+
+    // Send to LED strip with proper timing
+    sk6812_rgbw_send(offset, output_buffer, len);
+    free(output_buffer);
+}
+```
+
+### Key Implementation Notes
+
+- **Ping Response**: Must respond to ping (0x01) within 1 second
+- **LED Data**: Direct forward to LED strip, with color order conversion if needed
+- **Color Order**: SK6812-RGBW requires G-R-B-W order, desktop sends R-G-B-W
+- **Control Commands**: Optional feature for hardware with input capabilities
+- **mDNS Registration**: Essential for automatic device discovery
+- **UDP Server**: Must handle concurrent connections from multiple desktops
+- **LED Chip Support**: Must support WS2812B (RGB), SK6812 (RGB), and SK6812-RGBW
+
+## Troubleshooting
+
+### Device Discovery Issues
+
+**Device Not Found**:
+
+- Verify mDNS service registration on hardware
+- Check service type: `_ambient_light._udp.local.`
+- Ensure port 23042 is accessible
+- Verify network connectivity between desktop and hardware
+
+**Device Shows as Disconnected**:
+
+- Check ping/pong response implementation
+- Verify hardware responds to 0x01 packets within 1 second
+- Monitor network latency and packet loss
+- Check UDP server implementation on hardware
+
+### LED Control Issues
+
+**No LED Updates**:
+
+- Verify hardware processes 0x02 packets correctly
+- Check WS2812 wiring and power supply
+- Monitor packet reception on hardware side
+- Verify byte offset calculations and LED strip configuration
+
+**Wrong Colors**:
+
+- Check color calibration settings on desktop
+- Verify RGB/RGBW data format matches LED strip type
+- Monitor color data in packets (bytes 3+)
+- Check LED chip color order:
+  - WS2812B: G-R-B order
+  - SK6812: G-R-B order
+  - SK6812-RGBW: G-R-B-W order
+- Ensure hardware converts R-G-B(-W) from desktop to correct chip order
+
+**Flickering or Lag**:
+
+- Monitor packet rate and network congestion
+- Check power supply stability for LED strips
+- Verify WS2812 data signal integrity
+- Consider reducing update frequency
+
+### Control Protocol Issues
+
+**Brightness/Volume Control Not Working**:
+
+- Verify hardware sends correct packet format (0x03/0x04)
+- Check desktop receives and processes control packets
+- Monitor packet transmission from hardware
+- Verify display index and value ranges
+
+### Connection State Issues
+
+**Frequent Disconnections**:
+
+- Check network stability and latency
+- Verify ping response timing (< 1 second)
+- Monitor retry logic and connection state transitions
+- Check for UDP packet loss
+
+**Stuck in Connecting State**:
+
+- Verify ping/pong packet format
+- Check hardware UDP server implementation
+- Monitor ping response timing
+- Verify network firewall settings
+
+### Network Debugging
+
+**Packet Monitoring**:
+
+```bash
+# Monitor UDP traffic on port 23042
+tcpdump -i any -X port 23042
+
+# Check mDNS service discovery
+dns-sd -B _ambient_light._udp.local.
+```
+
+**Hardware Debug Output**:
+
+- Log received packet headers and lengths
+- Monitor ping/pong timing
+- Track LED data processing
+- Log mDNS service registration status
+
+## Protocol Version
+
+- **Current**: 1.0
+- **Headers**: 0x01 (Ping/Pong), 0x02 (LED Data), 0x03 (Brightness), 0x04 (Volume)
+- **Future**: Additional headers for new features, backward compatibility maintained
