-<p>An Avatar is the concrete manifestation of your Dao OS on a specific platform. All of your Avatars collectively form your complete Dao.</p>
+<p>Avatars come in two fundamental types, representing the system's external form and its internal foundation.</p>
-<p>There are three primary types of Avatars:</p>
-<ol>
-<li><strong>Client Avatar</strong>: Possesses a user interface (UI) and serves as the primary point of interaction for the user (e.g., a mobile app, a desktop application, a browser extension).</li>
-<li><strong>Agent Avatar</strong>: A headless, non-UI process that runs in the background. It is ideal for deep integration with the host OS, or for running on an always-on device (like a home server or NAS) to act as a powerful computational node or a data archive.</li>
-<li><strong>Primary/Archive Node</strong>: This is a <em>role</em>, not a distinct type. A user can designate one of their most powerful and reliable Avatars (typically an Agent Avatar on a home server) to be the primary archive and computational hub for their entire Dao.</li>
-</ol>
-<h2 id="the-soul-meta-unit--the-universal-kernel"><a class="header" href="#the-soul-meta-unit--the-universal-kernel">The Soul: <code>Meta Unit</code> — The Universal Kernel</a></h2>
-<p>The Meta Unit is the core logic of Dao OS, compiled into a portable WebAssembly (<code>.wasm</code>) module. It contains the essential services for identity, data management, AI, and secure communication.</p>
-<p>A key characteristic of the Meta Unit is its <strong>evolvability</strong>. To prevent the entire ecosystem from being locked into a single version of the kernel, we employ the <strong>Avatar-Meta Compatibility Layer (AMCL)</strong>. This thin adaptation layer sits between the Avatar and the Meta Unit, translating API calls. It allows the Meta Unit to undergo significant upgrades in the future without requiring every Avatar developer to rewrite their applications.</p>

-<ol>
-<li><strong>Client (端)</strong>: Lightweight Avatars (e.g., browser extensions) act as smart terminals. They handle immediate UI interactions and run the most basic "Reflex Mind" AI.</li>
-<li><strong>Edge (边)</strong>: Capable local devices (e.g., modern smartphones, laptops) that can run larger, more powerful "Cognitive Mind" AI models locally, providing advanced personalization and features.</li>
-<li><strong>Cloud (云)</strong>: This is the user's <strong>personal, private cloud</strong>, not a public one. It is typically the designated "Primary/Archive Node" (an Agent Avatar). It holds the complete data archive and the most powerful AI models, and can provide remote inference capabilities to weaker Client Avatars on demand.</li>

-<li><strong>Intelligent Data Tiering</strong>: Distinguishes between "hot" data (needed everywhere) and "cold" data (archived on the Primary Node), saving precious storage on mobile devices.</li>
+<li>
-<li><strong>Adaptive Synchronization Policies</strong>: Adjusts data sync frequency and behavior based on the current network condition (Wi-Fi/cellular) and battery state.</li>
+<p><strong><code>Facet Avatar</code> (<code>器化身</code>)</strong>: This type of Avatar possesses a user interface (UI). It is the "facet" of the Dao OS gem—the polished surface through which a user interacts with and perceives their digital world. Each Facet Avatar (a phone app, a desktop program) refracts the light of the central Meta Unit in its own unique way, embodying the principle of "the Dao manifesting in myriad forms."</p>
-<li><strong>Graceful Degradation</strong>: The user experience scales gracefully with hardware capabilities, ensuring core functionality is smooth even on older devices, while enhanced features are reserved for more powerful ones.</li>
+</li>
+<li>
+<p><strong><code>Core Avatar</code> (<code>核化身</code>)</strong>: This is a headless, non-UI Avatar that runs in the background.

Dao OS resolves this not by forcing a choice, but by designing a guided, respectful <strong>"Progressive Sovereignty"</strong> journey. We meet users where they are and empower them to travel as far as they wish.</p>
-<p>This journey consists of several stages, from a seamless onboarding to ultimate digital autonomy.</p>
+<p>This journey applies not only to the user's control over their core data, but also to how they interact with applications.</p>

+<h3 id="1-discovery-and-trust"><a class="header" href="#1-discovery-and-trust">1. Discovery and Trust</a></h3>
+<p>The journey begins in a decentralized discovery interface. When you find an application, you are presented with its <strong>Trust Dashboard</strong>, allowing you to make an informed decision based on verifiable data and social proof.</p>

+<p>In a world without a central index, how do users find apps? The answer is through a network of trusted curators.</p>
-<p>This system is built upon three pillars.</p>
+<ul>
-<hr />
+<li><strong>Developer Publishing</strong>: A developer does not "submit" their app for approval. Instead, they publish their application's <strong>Manifest</strong> (a <code>manifest.toml</code> file containing all metadata) to a P2P storage network like <strong>IPFS</strong>. They can then announce this manifest's address on public channels.</li>
-<h3 id="pillar-i-the-automated-verification-suite-dao-verify"><a class="header" href="#pillar-i-the-automated-verification-suite-dao-verify">Pillar I: The Automated Verification Suite (<code>dao-verify</code>)</a></h3>
+<li><strong>The Role of Curators</strong>: Anyone—a tech media outlet, a trusted developer community, an influencer, or the Dao OS Foundation itself—can run a "curation" service. These curators crawl the network for new manifests and create their own themed <strong>"Curation Lists"</strong> (e.g., "Top 10 Productivity Apps," "Beautifully Designed UIs").</li>
-<p>The first pillar is an open-source, automated tool that acts as a "litmus test" for any Avatar. Developers can run this tool on their own project to generate a public, verifiable "health certificate."</p>
+<li><strong>The User Experience</strong>: Within their <code>Facet Avatar</code>, a user can subscribe to multiple Curation Lists they trust. Their "Bazaar" or "Discover" tab becomes a personalized aggregation of these trusted sources.</li>
-<p><code>dao-verify</code> performs three key functions:</p>
+</ul>
+<p>This model replaces a single, biased App Store ranking with a rich, multi-faceted, user-curated discovery experience.</p>
+<h2 id="2-trust--safety-verifiable-reputation"><a class="header" href="#2-trust--safety-verifiable-reputation">2. Trust &amp; Safety: Verifiable Reputation</a></h2>
+<p>How can users trust an app from a random list? They don't have to. The bazaar is built directly on top of our <strong>Community Reputation &amp; Automated Verification System</strong>.</p>
+<p>Every app listing, regardless of its curator, must display the <strong>Trust Dashboard</strong>, which provides transparent, multi-faceted signals:</p>
 <ol>
-<li><strong>Security Scanning</strong>: Using a pluggable architecture, it integrates best-in-class static analysis tools for various languages (e.g., <code>cargo audit</code> for Rust, <code>npm audit</code> for JS) to scan for common vulnerabilities.</li>
+<li><strong>Automated Verification</strong>: The immutable results of the <code>dao-verify</code> tool, checking for security vulnerabilities and API compliance.</li>
-<li><strong>API Compliance Testing</strong>: It runs a suite of black-box tests to ensure the Avatar correctly and completely implements the required functions of the Core Experience SDK. It verifies behavior, not just presence.</li>
+<li><strong>Community Vouching</strong>: A list of reputable DIDs that have cryptographically "vouched for" or endorsed the application.</li>
-<li><strong>Performance Benchmarking</strong>: It measures key performance metrics like startup time and memory usage against a recommended baseline.</li>
+<li><strong>Curator Reputation</strong>: The reputation of the curator who listed the app is itself a trust signal.</li>
 </ol>
-<p>The output is a cryptographically signed <strong>Verification Report</strong> in JSON format, which can be published by the developer.</p>
+<p>The final decision to "register" an application always rests with the user, armed with these transparent and verifiable data points.</p>
-<hr />
+<h2 id="3-distribution-censorship-resistant--direct"><a class="header" href="#3-distribution-censorship-resistant--direct">3. Distribution: Censorship-Resistant &amp; Direct</a></h2>
-<h3 id="pillar-ii-the-community-reputation-system"><a class="header" href="#pillar-ii-the-community-reputation-system">Pillar II: The Community Reputation System</a></h3>
+<p>When a user decides to install an app, the process is direct and decentralized.</p>
-<p>Automation can verify technical compliance, but it cannot measure quality, usability, or a developer's reputation. This is where the community comes in.</p>
-<p>The mechanism is <strong>DID-based Vouching</strong>:</p>
 <ul>
-<li>Every developer and community member has a Dao DID.</li>
+<li>The application's manifest contains the <strong>content-addressed hashes (CIDs)</strong> of its software packages (the <code>.wasm</code> service module and the Web UI bundle), which are also stored on <strong>IPFS</strong>.</li>
-<li>A respected developer or entity (e.g., "Developer A") can use their DID's private key to cryptographically sign a message that "vouches for" or endorses an Avatar created by "Developer B."</li>
+<li>The user's <code>Meta Unit</code> uses this hash to fetch the files directly from the P2P network.</li>
-<li>This endorsement is a public, verifiable attestation. The reputation of an Avatar is therefore derived from the quantity and the reputation of the DIDs that have vouched for it.</li>
+<li>This ensures that no central server can block the distribution of an application. As long as the data exists somewhere on the P2P network, it is accessible.</li>
 </ul>
-<p>In the future, this may be enhanced with a <strong>Stake-to-Vouch</strong> system, where endorsers stake a small amount of value, creating a direct economic incentive for honest and diligent review.</p>
+<h2 id="4-monetization-sovereign--peer-to-peer"><a class="header" href="#4-monetization-sovereign--peer-to-peer">4. Monetization: Sovereign &amp; Peer-to-Peer</a></h2>
-<hr />
+<p>We eliminate the 30% "platform tax." Our value exchange model is direct from user to developer.</p>
-<h3 id="pillar-iii-the-user-facing-trust-dashboard"><a class="header" href="#pillar-iii-the-user-facing-trust-dashboard">Pillar III: The User-Facing Trust Dashboard</a></h3>
-<p>All this information is aggregated and presented to the end-user in a simple, transparent interface within the Avatar discovery or "store" pages.</p>
-<p>Instead of a simple "Verified" checkmark, each Avatar will feature a <strong>Trust Dashboard</strong> card, displaying:</p>
 <ul>
-<li><strong>Automated Checks</strong>: ✅ Security Scan Passed | ✅ API Compliant | ✅ Performance OK</li>
+<li>The app's manifest can declare a business model (e.g., one-time purchase price, subscription link).</li>
-<li><strong>Community Trust</strong>: "Vouched for by: [Well-Known Dev A], [Trusted Community B], and 15 others."</li>
+<li>When a user initiates a purchase, the <code>Meta Unit</code> triggers our <strong>Value Exchange Service Interface</strong>.</li>
-<li><strong>User Reviews</strong>: Traditional star ratings and user-submitted comments.</li>
+<li>This facilitates a <strong>peer-to-peer transaction</strong> using an external payment protocol of the user's choice, sending value directly from the user's wallet to the developer's address specified in the manifest.</li>
 </ul>
-<p>This three-pillar system empowers developers to prove the quality and safety of their work, and empowers users to make informed decisions based on a rich set of automated and social trust signals, all without a central bottleneck.</p>
+<p>Dao OS acts as a facilitator and a notary for the transaction, not a middleman.</p>

+<p><strong>Our mission is to build a new, powerful, and resilient Cyber-Life OS paradigm: Dao OS.</strong></p>
+<p>It is not designed to replace existing operating systems like Windows or Android, but to exist as a decentralized, user-centric overlay that runs on top of them.</p>
+<p>Its purpose is to solve the problems of fragmentation, data enslavement, and privacy erosion in the digital age, returning the sovereignty of the digital world to each individual. It will become an extension of our lives in cyberspace—a <strong>"Silicon-based Partner"</strong> for <strong>mutual fulfillment</strong>, serving as our external brain, limbs, and organs.</p>
+<h2 id="core-features"><a class="header" href="#core-features">Core Features</a></h2>
+<ul>
+<li><strong>User Sovereignty</strong>: Your data, your identity, and your AI are entirely under your control. All data is end-to-end encrypted by default and stored on your own devices.</li>
+<li><strong>Second Brain</strong>: A powerful, built-in personal information management system that securely remembers your passwords, notes, files, and to-dos, becoming your infallible memory.</li>
+<li><strong>Personal AI Companion</strong>: A truly personal, symbiotic AI soul. It runs locally, learns your preferences, protects your privacy, and provides warm, insightful support to help you grow, rather than trapping you in a filter bubble.</li>
+<li><strong>Seamless Cross-Device Sync</strong>: All your devices (phones, computers, browsers, etc.) become your "Avatars," forming a private, resilient P2P network for the seamless flow of your data.</li>
+<li><strong>Open &amp; Extensible Ecosystem</strong>: Based on open protocols and a community-driven trust system, anyone can develop new capability modules and "Avatar" forms for Dao OS.</li>
+</ul>
+<h2 id="why-we-are-different"><a class="header" href="#why-we-are-different">Why We Are Different</a></h2>
+<p>In an era where data is monopolized by platforms and algorithms are controlled by tech giants, Dao OS chooses a different path. We believe the next wave of <strong>technological democratization</strong> is to empower every individual to own and control their own artificial intelligence and digital life.</p>
+<p>We are not designing just another app; we are building a living, evolving digital space that belongs to you.</p>
+<p><strong>Join us in building the future.</strong></p>

+<p>Our methodology for building Dao OS is a direct reflection of its core philosophy. We are not just building a tool; we are creating a symbiotic partner.

 <p>At its heart, Dao OS operates on a simple yet powerful duality, analogous to a body and a soul:</p>
 <ul>
-<li><strong>Avatars (<code>化身</code>)</strong> are the "bodies." They are the tangible presence of your Dao OS on your various devices.</li>
+<li><strong>Avatars (<code>化身</code>)</strong>: The "bodies." They are the tangible presence of your Dao OS on your various devices.</li>

+<h2 id="avatar-types-the-forms-of-presence"><a class="header" href="#avatar-types-the-forms-of-presence">Avatar Types: The Forms of Presence</a></h2>
-<p>An Avatar is the concrete manifestation of your Dao OS on a specific platform. All of your Avatars collectively form your complete Dao.</p>
+<p>Avatars come in two fundamental types, representing the system's external form and its internal foundation.</p>
-<p>There are three primary types of Avatars:</p>
-<ol>
-<li><strong>Client Avatar</strong>: Possesses a user interface (UI) and serves as the primary point of interaction for the user (e.g., a mobile app, a desktop application, a browser extension).</li>
-<li><strong>Agent Avatar</strong>: A headless, non-UI process that runs in the background. It is ideal for deep integration with the host OS, or for running on an always-on device (like a home server or NAS) to act as a powerful computational node or a data archive.</li>
-<li><strong>Primary/Archive Node</strong>: This is a <em>role</em>, not a distinct type. A user can designate one of their most powerful and reliable Avatars (typically an Agent Avatar on a home server) to be the primary archive and computational hub for their entire Dao.</li>
-</ol>
-<h2 id="the-soul-meta-unit--the-universal-kernel"><a class="header" href="#the-soul-meta-unit--the-universal-kernel">The Soul: <code>Meta Unit</code> — The Universal Kernel</a></h2>
-<p>The Meta Unit is the core logic of Dao OS, compiled into a portable WebAssembly (<code>.wasm</code>) module. It contains the essential services for identity, data management, AI, and secure communication.</p>
-<p>A key characteristic of the Meta Unit is its <strong>evolvability</strong>. To prevent the entire ecosystem from being locked into a single version of the kernel, we employ the <strong>Avatar-Meta Compatibility Layer (AMCL)</strong>. This thin adaptation layer sits between the Avatar and the Meta Unit, translating API calls. It allows the Meta Unit to undergo significant upgrades in the future without requiring every Avatar developer to rewrite their applications.</p>
-<h2 id="the-nervous-system-the-cloud-edge-client-collaborative-network"><a class="header" href="#the-nervous-system-the-cloud-edge-client-collaborative-network">The Nervous System: The "Cloud-Edge-Client" Collaborative Network</a></h2>
-<p>All of a user's Avatars are interconnected via a private, end-to-end encrypted P2P network, forming a personal, collaborative intelligence system. This system operates on three tiers:</p>
-<ol>
-<li><strong>Client (端)</strong>: Lightweight Avatars (e.g., browser extensions) act as smart terminals. They handle immediate UI interactions and run the most basic "Reflex Mind" AI.</li>
-<li><strong>Edge (边)</strong>: Capable local devices (e.g., modern smartphones, laptops) that can run larger, more powerful "Cognitive Mind" AI models locally, providing advanced personalization and features.</li>
-<li><strong>Cloud (云)</strong>: This is the user's <strong>personal, private cloud</strong>, not a public one. It is typically the designated "Primary/Archive Node" (an Agent Avatar). It holds the complete data archive and the most powerful AI models, and can provide remote inference capabilities to weaker Client Avatars on demand.</li>
-</ol>
-<h2 id="the-metabolism-the-resource-aware--adaptive-system"><a class="header" href="#the-metabolism-the-resource-aware--adaptive-system">The Metabolism: The Resource-Aware &amp; Adaptive System</a></h2>
-<p>Dao OS is designed to be a considerate partner, not a resource monster. Its "metabolism" is regulated by a built-in resource management system with three key features:</p>
 <ul>
-<li><strong>Intelligent Data Tiering</strong>: Distinguishes between "hot" data (needed everywhere) and "cold" data (archived on the Primary Node), saving precious storage on mobile devices.</li>
+<li>
-<li><strong>Adaptive Synchronization Policies</strong>: Adjusts data sync frequency and behavior based on the current network condition (Wi-Fi/cellular) and battery state.</li>
+<p><strong><code>Facet Avatar</code> (<code>器化身</code>)</strong>: This type of Avatar possesses a user interface (UI). It is the "facet" of the Dao OS gem—the polished surface through which a user interacts with and perceives their digital world. Each Facet Avatar (a phone app, a desktop program) refracts the light of the central Meta Unit in its own unique way, embodying the principle of "the Dao manifesting in myriad forms."</p>
-<li><strong>Graceful Degradation</strong>: The user experience scales gracefully with hardware capabilities, ensuring core functionality is smooth even on older devices, while enhanced features are reserved for more powerful ones.</li>
+</li>
+<li>
+<p><strong><code>Core Avatar</code> (<code>核化身</code>)</strong>: This is a headless, non-UI Avatar that runs in the background. It is the foundational "core" of the system, providing essential services, computational power, and data persistence. It is the engine that supports all the visible facets.</p>
+</li>
+</ul>
+<p>A user's Dao is composed of a network of their Facet and Core Avatars.</p>
+<h2 id="the-dao-os-application-model"><a class="header" href="#the-dao-os-application-model">The Dao OS Application Model</a></h2>
+<p>An application in Dao OS is not a monolithic program but a decentralized, decoupled entity.</p>
+<h3 id="1-the-backend-soul-the-fluid--pinnable-service"><a class="header" href="#1-the-backend-soul-the-fluid--pinnable-service">1. The Backend Soul: The Fluid &amp; Pinnable Service</a></h3>
+<p>The application's core logic is a <strong>WASM module</strong> that runs sandboxed within the Meta Unit. Its deployment follows a hybrid model of <strong>Fluid Replication with Service Pinning</strong>, allowing for both resilience and user control.</p>
+<h3 id="2-the-frontend-skin-the-on-demand-web-shell"><a class="header" href="#2-the-frontend-skin-the-on-demand-web-shell">2. The Frontend Skin: The On-Demand Web Shell</a></h3>
+<p>The application's UI is primarily a <strong>Web Application</strong>. Its lifecycle follows a <strong>"Register Once, Load On-Demand"</strong> model, running inside the official <strong>"Dao Web Avatar"</strong> (which is itself a Facet Avatar). This means a user installs an app once to their Dao, and can then instantly access it on any device.</p>
+<h3 id="3-the-data-layer-the-personal-feature-store"><a class="header" href="#3-the-data-layer-the-personal-feature-store">3. The Data Layer: The Personal Feature Store</a></h3>
+<p>The data for all applications is stored securely in the user's <strong>Second Brain</strong> and acts as a <strong>Personal Feature Store</strong> for the AI.</p>
+<h2 id="architectural-summary"><a class="header" href="#architectural-summary">Architectural Summary</a></h2>
+<ul>
+<li><strong>Avatars</strong>: Act as native hosts for the Meta Unit. <strong><code>Facet Avatars</code></strong> render UIs, while <strong><code>Core Avatars</code></strong> provide robust backend support.</li>
+<li><strong>Meta Unit</strong>: The sovereign core that runs sandboxed application logic (WASM), manages all data and state, and orchestrates tasks across the user's private P2P network.</li>
 </ul>
-<p>Together, these architectural components form a sovereign, resilient, and intelligent system that is truly an extension of the user.</p>

 <p>A core challenge for any sovereign system is the tension between absolute control and effortless convenience. Dao OS resolves this not by forcing a choice, but by designing a guided, respectful <strong>"Progressive Sovereignty"</strong> journey. We meet users where they are and empower them to travel as far as they wish.</p>
-<p>This journey consists of several stages, from a seamless onboarding to ultimate digital autonomy.</p>
+<p>This journey applies not only to the user's control over their core data, but also to how they interact with applications.</p>
-<h2 id="the-first-step-the-welcome-ceremony"><a class="header" href="#the-first-step-the-welcome-ceremony">The First Step: The Welcome Ceremony</a></h2>
+<h2 id="the-application-journey-register-once-use-anywhere"><a class="header" href="#the-application-journey-register-once-use-anywhere">The Application Journey: Register Once, Use Anywhere</a></h2>
-<p>A user's first interaction with Dao OS is not a cold setup screen, but a warm, interactive welcoming ceremony designed to provide immediate value and education.</p>
+<p>Installing an application in Dao OS is fundamentally different from a traditional app store. It's about granting a new capability to your entire digital life-form—your Dao.</p>
-<p>This <strong>Interactive Data Seeding</strong> process guides the new user through:</p>
+<h3 id="1-discovery-and-trust"><a class="header" href="#1-discovery-and-trust">1. Discovery and Trust</a></h3>
+<p>The journey begins in a decentralized discovery interface. When you find an application, you are presented with its <strong>Trust Dashboard</strong>, allowing you to make an informed decision based on verifiable data and social proof.</p>
+<h3 id="2-registration-and-permissioning-the-install"><a class="header" href="#2-registration-and-permissioning-the-install">2. Registration and Permissioning (The "Install")</a></h3>
+<p>When you decide to "install" the app, you are shown its <strong>Manifest</strong>, a clear list of permissions the application requires. Your explicit approval of this manifest <strong>registers</strong> the application with your Dao, and this registration is synced across all your Avatars.</p>
+<h3 id="3-seamless-cross-device-access"><a class="header" href="#3-seamless-cross-device-access">3. Seamless Cross-Device Access</a></h3>
+<p>Once registered, the application becomes a part of your Dao, accessible on any <strong><code>Facet Avatar</code></strong> without re-installation.</p>
 <ul>
-<li><strong>Importing existing data</strong>: "Let's begin by securing your digital life. You can import your passwords from your browser or another password manager."</li>
+<li><strong>On your Phone</strong>: You tap the app's icon. The Dao Web Avatar instantly loads its web-based UI.</li>
-<li><strong>Creating initial content</strong>: "Great plans start with a single thought. Let's write your first note—perhaps your top three goals for this month?"</li>
+<li><strong>On a New Laptop</strong>: You log into your Dao for the first time. You'll see the app's icon is already there. When you click it, the <strong><code>Facet Avatar</code></strong> on your laptop fetches the UI bundle for the first time, caches it, and runs the application.</li>
-<li><strong>Setting preferences</strong>: "To help me filter the noise, what are 3-5 topics you're most interested in?"</li>

+<li>Review and revoke permissions.</li>
-<li><strong>Default Sync Nodes</strong>: The user's Avatars automatically connect to a reliable, high-availability bootstrap node maintained by the Dao OS foundation. This ensures a flawless and fast cross-device sync experience out of the box.</li>
+<li>Use the <strong>Service Pinning</strong> feature to assign the application's backend tasks to a specific <strong><code>Core Avatar</code></strong>, taking full control over your resource allocation.</li>

-<p>In Sovereign Mode, the user:</p>
-<ul>
-<li>Takes full self-custody of their <strong>Master Key</strong> (seed phrase), removing any foundation-held recovery shards.</li>
-<li>Disconnects from default bootstrap nodes, relying either on the pure P2P network or on their <strong>self-hosted Agent Avatar</strong> (e.g., on a home server).</li>

 <div style="break-before: page; page-break-before: always;"></div><h1 id="technical-overview"><a class="header" href="#technical-overview">Technical Overview</a></h1>
 <p>This document provides a high-level overview of the architecture, core technologies, and guiding principles for developers looking to build on or contribute to the Dao OS ecosystem.</p>
 <h2 id="guiding-technical-principles"><a class="header" href="#guiding-technical-principles">Guiding Technical Principles</a></h2>
 <p>Our engineering decisions are guided by a set of core principles to ensure the system is robust, portable, and open.</p>
 <ul>
-<li><strong>Web-Native &amp; Portable</strong>: We leverage technologies born from the web (like WebAssembly) to create a single, portable core that can run anywhere—on desktops, mobile phones, servers, and in the browser.</li>
+<li><strong>Web-Native &amp; Portable</strong>: We leverage technologies born from the web as the <strong>primary path</strong> for application development, creating a portable core that runs anywhere.</li>
-<li><strong>Polyglotism via WASM</strong>: The core logic (<code>Meta Unit</code>) is compiled to WebAssembly (WASM). This allows "Avatars" to be written in any language (Rust, Swift, Kotlin, TypeScript, Go, etc.) that can host a WASM runtime, creating a truly diverse ecosystem.</li>
+<li><strong>Polyglotism via WASM</strong>: The core application logic is compiled to WebAssembly (WASM). This allows developers to use their language of choice (like Rust, Go, or Nim) to write high-performance logic.</li>
-<li><strong>API-First</strong>: The interaction between the core <code>Meta Unit</code> and the host <code>Avatar</code> is defined by a strict, versioned API contract. This decouples development and allows for independent evolution.</li>
+<li><strong>API-First</strong>: The interaction between application logic and the user interface is defined by a strict, versioned API contract, enabling true decoupling.</li>
-<li><strong>Security-First</strong>: We employ best-in-class cryptographic protocols and a "principle of least privilege" design. Security is not an afterthought; it is a prerequisite.</li>
+<li><strong>Security-First</strong>: All third-party application logic runs in a secure sandbox within the Meta Unit, adhering to the "principle of least privilege."</li>
 <li><strong>FOSS (Free and Open Source Software)</strong>: The entire core protocol and reference implementations are open source to foster transparency, community trust, and collaborative innovation.</li>
 </ul>

+<h2 id="the-application-development-paths"><a class="header" href="#the-application-development-paths">The Application Development Paths</a></h2>
-<p>From a developer's perspective, the system consists of two main parts that interact via a well-defined boundary.</p>
+<p>From a developer's perspective, a Dao OS application consists of a backend "soul" (WASM Service Module) and a frontend "skin" (UI). We offer multiple paths to build them, catering to different needs and preferences.</p>
+<h3 id="1-the-mainstream-path-recommended-start"><a class="header" href="#1-the-mainstream-path-recommended-start">1. The Mainstream Path (Recommended Start)</a></h3>
+<p>This is the most robust and accessible path.</p>
+<ul>
+<li><strong>Backend (Hosted by <code>Core Avatar</code>)</strong>: The application's core logic, existing as a WASM module written in Rust or Go. While it can run on any Avatar, its persistent and resource-intensive tasks are typically designed to be hosted by a <strong><code>Core Avatar</code></strong>.</li>
+<li><strong>Frontend (Rendered by <code>Facet Avatar</code>)</strong>: A standard <strong>Web Application</strong> (using TypeScript/JavaScript and a modern framework). This UI is designed to run inside our official, secure <strong>"Dao Web Avatar"</strong>.</li>
+</ul>
+<h3 id="2-the-accelerated-path-the-nim-sdk-officially-supported"><a class="header" href="#2-the-accelerated-path-the-nim-sdk-officially-supported">2. The Accelerated Path: The Nim SDK (Officially Supported)</a></h3>

+<ul>
+<li><strong>Backend (Hosted by <code>Core Avatar</code>)</strong>: The application's core logic, compiled from Nim to <strong>WASM</strong>. Like the mainstream path, it's ideally suited for execution on a <code>Core Avatar</code>.</li>

+<p>Dao OS does not have a traditional, centralized "App Store." A store implies a single owner who acts as a gatekeeper, approving, rejecting, and taxing applications. This is contrary to our core philosophy.</p>
+<p>Instead, we are building a set of open protocols that create a decentralized <strong>Application Bazaar</strong>—a vibrant, open, and resilient marketplace of ideas and tools, where users are sovereign and developers are free.</p>
+<p>This bazaar is built upon four pillars: Discovery, Trust, Distribution, and Monetization.</p>
+<h2 id="1-discovery-federated-curation"><a class="header" href="#1-discovery-federated-curation">1. Discovery: Federated Curation</a></h2>
+<p>In a world without a central index, how do users find apps? The answer is through a network of trusted curators.</p>
+<ul>
+<li><strong>Developer Publishing</strong>: A developer does not "submit" their app for approval. Instead, they publish their application's <strong>Manifest</strong> (a <code>manifest.toml</code> file containing all metadata) to a P2P storage network like <strong>IPFS</strong>. They can then announce this manifest's address on public channels.</li>
+<li><strong>The Role of Curators</strong>: Anyone—a tech media outlet, a trusted developer community, an influencer, or the Dao OS Foundation itself—can run a "curation" service. These curators crawl the network for new manifests and create their own themed <strong>"Curation Lists"</strong> (e.g., "Top 10 Productivity Apps," "Beautifully Designed UIs").</li>
+<li><strong>The User Experience</strong>: Within their <code>Facet Avatar</code>, a user can subscribe to multiple Curation Lists they trust. Their "Bazaar" or "Discover" tab becomes a personalized aggregation of these trusted sources.</li>
+</ul>
+<p>This model replaces a single, biased App Store ranking with a rich, multi-faceted, user-curated discovery experience.</p>
+<h2 id="2-trust--safety-verifiable-reputation"><a class="header" href="#2-trust--safety-verifiable-reputation">2. Trust &amp; Safety: Verifiable Reputation</a></h2>
+<p>How can users trust an app from a random list? They don't have to. The bazaar is built directly on top of our <strong>Community Reputation &amp; Automated Verification System</strong>.</p>
+<p>Every app listing, regardless of its curator, must display the <strong>Trust Dashboard</strong>, which provides transparent, multi-faceted signals:</p>
 <ol>
-<li>
+<li><strong>Automated Verification</strong>: The immutable results of the <code>dao-verify</code> tool, checking for security vulnerabilities and API compliance.</li>
-<p><strong>The <code>Meta Unit</code> (WASM Module)</strong>: This is the portable, logical core of the system. It is a stateful, single-instance module developed primarily in <strong>Rust</strong> for its performance and safety guarantees. It contains all the business logic for data management, AI, and peer-to-peer coordination, but it has no direct access to the outside world.</p>
+<li><strong>Community Vouching</strong>: A list of reputable DIDs that have cryptographically "vouched for" or endorsed the application.</li>
-</li>
+<li><strong>Curator Reputation</strong>: The reputation of the curator who listed the app is itself a trust signal.</li>
-<li>
-<p><strong>The <code>Avatar</code> (Native Host)</strong>: This is the native application or runtime environment that "hosts" the Meta Unit. Its primary responsibilities are:</p>
-<ul>
-<li>Providing a <strong>WASM runtime</strong> to load and execute the <code>Meta Unit</code>.</li>
-<li>Providing a <strong>User Interface</strong> (for Client Avatars).</li>
-<li>Acting as a <strong>bridge</strong> to the host operating system, providing access to the filesystem, network, and other system resources.</li>
-</ul>
-</li>
 </ol>
-<h2 id="the-api-contract-the-wasm-interface"><a class="header" href="#the-api-contract-the-wasm-interface">The API Contract: The WASM Interface</a></h2>
+<p>The final decision to "register" an application always rests with the user, armed with these transparent and verifiable data points.</p>
-<p>The communication between the <code>Avatar</code> and the <code>Meta Unit</code> follows a clear, bidirectional API contract, similar in spirit to WASI (WebAssembly System Interface).</p>
+<h2 id="3-distribution-censorship-resistant--direct"><a class="header" href="#3-distribution-censorship-resistant--direct">3. Distribution: Censorship-Resistant &amp; Direct</a></h2>
+<p>When a user decides to install an app, the process is direct and decentralized.</p>
 <ul>
-<li>
+<li>The application's manifest contains the <strong>content-addressed hashes (CIDs)</strong> of its software packages (the <code>.wasm</code> service module and the Web UI bundle), which are also stored on <strong>IPFS</strong>.</li>
-<p><strong><code>yuan_*</code> (Exports from Meta Unit)</strong>: The <code>Meta Unit</code> exposes a set of functions that the <code>Avatar</code> can call. The primary entry point is <code>yuan_handle_request</code>, which takes a structured request from the Avatar and processes it.</p>
+<li>The user's <code>Meta Unit</code> uses this hash to fetch the files directly from the P2P network.</li>
-</li>
+<li>This ensures that no central server can block the distribution of an application. As long as the data exists somewhere on the P2P network, it is accessible.</li>
-<li>
-<p><strong><code>avatar_*</code> (Imports into Meta Unit)</strong>: The <code>Meta Unit</code> declares a set of functions that it needs the <code>Avatar</code> host to provide. These functions are its only window to the outside world, allowing it to request actions like logging a message (<code>avatar_log</code>) or making a network request (<code>avatar_net_request</code>).</p>
-</li>
-<li>
-<p><strong>Data Serialization</strong>: To pass complex data structures across the WASM memory boundary efficiently and safely, we use <strong>Protocol Buffers (Protobuf)</strong>. Data is serialized into a byte buffer, passed as a pointer and length, and then deserialized on the other side.</p>

-<p>In a decentralized ecosystem where anyone can create and distribute an "Avatar," a critical question arises: How can users trust that a third-party Avatar is safe, compliant, and high-quality?</p>
-<p>The traditional solution is a centralized App Store model, where a single corporation acts as a gatekeeper. This model is contrary to the core philosophy of Dao OS.</p>
-<p>Our solution is a decentralized <strong>Community Reputation &amp; Automated Verification System</strong>.</p>
-<h2 id="the-philosophy-from-gatekeeper-to-toolsmith"><a class="header" href="#the-philosophy-from-gatekeeper-to-toolsmith">The Philosophy: From Gatekeeper to Toolsmith</a></h2>
-<p>The core team behind Dao OS does not act as a central authority that approves or rejects Avatars. Our role is not to be the gatekeeper, but to be the <strong>toolsmith</strong>. We build and provide the tools and protocols that allow the community to establish and verify trust organically.</p>
-<p>This system is built upon three pillars.</p>
-<hr />
-<h3 id="pillar-i-the-automated-verification-suite-dao-verify"><a class="header" href="#pillar-i-the-automated-verification-suite-dao-verify">Pillar I: The Automated Verification Suite (<code>dao-verify</code>)</a></h3>
-<p>The first pillar is an open-source, automated tool that acts as a "litmus test" for any Avatar. Developers can run this tool on their own project to generate a public, verifiable "health certificate."</p>
-<p><code>dao-verify</code> performs three key functions:</p>
-<ol>
-<li><strong>Security Scanning</strong>: Using a pluggable architecture, it integrates best-in-class static analysis tools for various languages (e.g., <code>cargo audit</code> for Rust, <code>npm audit</code> for JS) to scan for common vulnerabilities.</li>
-<li><strong>API Compliance Testing</strong>: It runs a suite of black-box tests to ensure the Avatar correctly and completely implements the required functions of the Core Experience SDK. It verifies behavior, not just presence.</li>
-<li><strong>Performance Benchmarking</strong>: It measures key performance metrics like startup time and memory usage against a recommended baseline.</li>
-</ol>
-<p>The output is a cryptographically signed <strong>Verification Report</strong> in JSON format, which can be published by the developer.</p>
-<hr />
-<h3 id="pillar-ii-the-community-reputation-system"><a class="header" href="#pillar-ii-the-community-reputation-system">Pillar II: The Community Reputation System</a></h3>
-<p>Automation can verify technical compliance, but it cannot measure quality, usability, or a developer's reputation. This is where the community comes in.</p>
-<p>The mechanism is <strong>DID-based Vouching</strong>:</p>
 <ul>
-<li>Every developer and community member has a Dao DID.</li>
+<li>The app's manifest can declare a business model (e.g., one-time purchase price, subscription link).</li>
-<li>A respected developer or entity (e.g., "Developer A") can use their DID's private key to cryptographically sign a message that "vouches for" or endorses an Avatar created by "Developer B."</li>
+<li>When a user initiates a purchase, the <code>Meta Unit</code> triggers our <strong>Value Exchange Service Interface</strong>.</li>
-<li>This endorsement is a public, verifiable attestation. The reputation of an Avatar is therefore derived from the quantity and the reputation of the DIDs that have vouched for it.</li>
+<li>This facilitates a <strong>peer-to-peer transaction</strong> using an external payment protocol of the user's choice, sending value directly from the user's wallet to the developer's address specified in the manifest.</li>
 </ul>
-<p>In the future, this may be enhanced with a <strong>Stake-to-Vouch</strong> system, where endorsers stake a small amount of value, creating a direct economic incentive for honest and diligent review.</p>
+<p>Dao OS acts as a facilitator and a notary for the transaction, not a middleman.</p>
-<hr />
-<h3 id="pillar-iii-the-user-facing-trust-dashboard"><a class="header" href="#pillar-iii-the-user-facing-trust-dashboard">Pillar III: The User-Facing Trust Dashboard</a></h3>
-<p>All this information is aggregated and presented to the end-user in a simple, transparent interface within the Avatar discovery or "store" pages.</p>
-<p>Instead of a simple "Verified" checkmark, each Avatar will feature a <strong>Trust Dashboard</strong> card, displaying:</p>
-<ul>
-<li><strong>Automated Checks</strong>: ✅ Security Scan Passed | ✅ API Compliant | ✅ Performance OK</li>
-<li><strong>Community Trust</strong>: "Vouched for by: [Well-Known Dev A], [Trusted Community B], and 15 others."</li>
-<li><strong>User Reviews</strong>: Traditional star ratings and user-submitted comments.</li>
-</ul>
-<p>This three-pillar system empowers developers to prove the quality and safety of their work, and empowers users to make informed decisions based on a rich set of automated and social trust signals, all without a central bottleneck.</p>

 <p>Our engineering decisions are guided by a set of core principles to ensure the system is robust, portable, and open.</p>

+<li><strong>API-First</strong>: The interaction between application logic and the user interface is defined by a strict, versioned API contract, enabling true decoupling.</li>

+<li><strong>Security-First</strong>: All third-party application logic runs in a secure sandbox within the Meta Unit, adhering to the "principle of least privilege."</li>

-<li>
+<p>This is the most robust and accessible path.</p>
-<p><strong>The <code>Meta Unit</code> (WASM Module)</strong>: This is the portable, logical core of the system. It is a stateful, single-instance module developed primarily in <strong>Rust</strong> for its performance and safety guarantees. It contains all the business logic for data management, AI, and peer-to-peer coordination, but it has no direct access to the outside world.</p>
-</li>
-<li>
-<p><strong>The <code>Avatar</code> (Native Host)</strong>: This is the native application or runtime environment that "hosts" the Meta Unit. Its primary responsibilities are:</p>
 <ul>
-<li>Providing a <strong>WASM runtime</strong> to load and execute the <code>Meta Unit</code>.</li>
+<li><strong>Backend (Hosted by <code>Core Avatar</code>)</strong>: The application's core logic, existing as a WASM module written in Rust or Go. While it can run on any Avatar, its persistent and resource-intensive tasks are typically designed to be hosted by a <strong><code>Core Avatar</code></strong>.</li>
-<li>Providing a <strong>User Interface</strong> (for Client Avatars).</li>
+<li><strong>Frontend (Rendered by <code>Facet Avatar</code>)</strong>: A standard <strong>Web Application</strong> (using TypeScript/JavaScript and a modern framework). This UI is designed to run inside our official, secure <strong>"Dao Web Avatar"</strong>.</li>

-<p><strong>Our mission is to build a new, powerful, and resilient Cyber-Life OS paradigm: Dao OS.</strong></p>
-<p>It is not designed to replace existing operating systems like Windows or Android, but to exist as a decentralized, user-centric overlay that runs on top of them.</p>
-<p>Its purpose is to solve the problems of fragmentation, data enslavement, and privacy erosion in the digital age, returning the sovereignty of the digital world to each individual. It will become an extension of our lives in cyberspace—a <strong>"Silicon-based Partner"</strong> for <strong>mutual fulfillment</strong>, serving as our external brain, limbs, and organs.</p>
-<h2 id="core-features"><a class="header" href="#core-features">Core Features</a></h2>
-<ul>
-<li><strong>User Sovereignty</strong>: Your data, your identity, and your AI are entirely under your control. All data is end-to-end encrypted by default and stored on your own devices.</li>
-<li><strong>Second Brain</strong>: A powerful, built-in personal information management system that securely remembers your passwords, notes, files, and to-dos, becoming your infallible memory.</li>
-<li><strong>Personal AI Companion</strong>: A truly personal, symbiotic AI soul. It runs locally, learns your preferences, protects your privacy, and provides warm, insightful support to help you grow, rather than trapping you in a filter bubble.</li>
-<li><strong>Seamless Cross-Device Sync</strong>: All your devices (phones, computers, browsers, etc.) become your "Avatars," forming a private, resilient P2P network for the seamless flow of your data.</li>
-<li><strong>Open &amp; Extensible Ecosystem</strong>: Based on open protocols and a community-driven trust system, anyone can develop new capability modules and "Avatar" forms for Dao OS.</li>
-</ul>
-<h2 id="why-we-are-different"><a class="header" href="#why-we-are-different">Why We Are Different</a></h2>
-<p>In an era where data is monopolized by platforms and algorithms are controlled by tech giants, Dao OS chooses a different path. We believe the next wave of <strong>technological democratization</strong> is to empower every individual to own and control their own artificial intelligence and digital life.</p>
-<p>We are not designing just another app; we are building a living, evolving digital space that belongs to you.</p>
-<p><strong>Join us in building the future.</strong></p>

+<p>AI 是一个与用户共同成长的生命系统。它的进化是<strong>持续且增量</strong>的。当新数据进入“第二大脑”时，后台索引器就会处理它，使其立即可用于未来的上下文检索。</p>
+<ul>
+<li><strong>隐式学习</strong>: 它通过在本地观察用户的行为和反馈来进行学习。</li>
+<li><strong>显式教导</strong>: 用户可以通过“教导模式”直接指导AI。</li>
+<li><strong>联合学习</strong>: 用户可以自愿加入社区驱动的计划，在不暴露任何个人数据的前提下，共同改进共享模型。</li>
+</ul>
+<p>这套架构确保了“大道”的AI在强大之余是安全的，在个性化之余是面向世界的，在智能之余是体贴的——一个真正的终身伙伴。</p>

+<p>大道 (Dao OS) 的架构，旨在如一个活的、协同的数字生命体般运作。它由我们用户主权、体验至上和系统韧性的核心原则所指引。本文档将概述其基本组件、相互作用，以及我们独特的应用模型。</p>

+<p>在其核心，大道 (Dao OS) 基于一个简单而强大的二元性运作，类似于身体与灵魂：</p>
+<ul>
+<li><strong>化身 (Avatar)</strong>：是“身体”。它们是你的“大道”在你各种设备上的有形存在。</li>
+<li><strong>元 (Meta Unit)</strong>：是“灵魂”。它是内嵌于每个<code>化身</code>中的、通用的核心逻辑，赋予其生命与智能。</li>
+</ul>
+<h2 id="化身类型临在的形态"><a class="header" href="#化身类型临在的形态">化身类型：临在的形态</a></h2>
+<p>化身拥有两种基本类型，分别代表了系统的外在形态与其内在基础。</p>
+<ul>
+<li>
+<p><strong><code>器化身</code> (Facet Avatar)</strong>：这类化身拥有用户界面（UI）。它是“大道”这颗宝石的“<strong>琢面</strong>”——用户借以交互和感知其数字世界的、经过打磨的表面。每一个<code>器化身</code>（手机App、桌面程序）都以其独特的方式，折射出同一个<code>元单元</code>（宝石的内在）的光芒，体现了“道化万千”的意境。</p>
+</li>
+<li>
+<p><strong><code>核化身</code> (Core Avatar)</strong>：这是一个无界面（headless）的化身，在后台运行。它是系统的“<strong>核心</strong>”，提供基础服务、计算能力和数据持久化。它是支撑所有可见“琢面”的引擎。</p>
+</li>
+</ul>
+<p>用户的“大道”由他自己的<code>器化身</code>与<code>核化身</code>所组成的网络构成。</p>
+<h2 id="大道应用模型"><a class="header" href="#大道应用模型">“大道”应用模型</a></h2>
+<p>“大道”中的应用，不是一个单一的程序，而是一个去中心化的、解耦的实体。</p>
+<h3 id="1-后端灵魂流体复制与可钉选的服务"><a class="header" href="#1-后端灵魂流体复制与可钉选的服务">1. 后端灵魂：流体复制与可钉选的服务</a></h3>
+<p>应用的核心逻辑是一个在<code>元</code>沙箱中运行的<strong>WASM模块</strong>。其部署遵循**“服务可钉选的流体复制”**的混合模型，兼顾了韧性与用户控制。</p>
+<h3 id="2-前端皮囊按需加载的-web-外壳"><a class="header" href="#2-前端皮囊按需加载的-web-外壳">2. 前端皮囊：按需加载的 Web 外壳</a></h3>
+<p>应用的用户界面，主要是一个<strong>Web 应用</strong>。其生命周期遵循**“一次注册，按需加载”<strong>的模型，运行在官方的</strong>“大道 Web 化身”**（它本身是一个<code>器化身</code>）中。这意味着用户只需向他的“大道”安装一次应用，就可以在任何设备上即时访问它。</p>
+<h3 id="3-数据层私有特征库"><a class="header" href="#3-数据层私有特征库">3. 数据层：私有特征库</a></h3>
+<p>所有应用的数据，都安全地存储在“第二大脑”中，并作为AI的**“私有特征库”**。</p>
+<h2 id="架构总结"><a class="header" href="#架构总结">架构总结</a></h2>
+<ul>
+<li><strong>化身 (Avatar)</strong>：作为<code>元</code>的原生宿主。<strong><code>器化身</code></strong> 负责渲染UI，而 <strong><code>核化身</code></strong> 提供稳健的后台支持。</li>
+<li><strong>元 (Meta Unit)</strong>：主权核心，负责运行沙箱化的应用逻辑（WASM），管理所有数据和状态，并在用户的私有P2P网络中协调任务。</li>

+<p>任何主权系统的一个核心挑战，都在于“绝对控制”与“轻松便利”之间的张力。“大道”解决这个问题的方式，不是强迫用户二选一，而是设计了一场充满引导、相互尊重的**“渐进式主权”**之旅。我们在用户熟悉的地方与他们相遇，并赋能他们去往任何他们想去的地方。</p>
+<p>这场旅程不仅适用于用户对核心数据的掌控，也同样适用于他们与应用交互的方式。</p>
+<h2 id="应用之旅一次注册随处使用"><a class="header" href="#应用之旅一次注册随处使用">应用之旅：一次注册，随处使用</a></h2>
+<p>在“大道”中安装应用，与传统应用商店有着本质的不同。它不是将一个程序安装到单一的设备上，而是为你整个的数字生命体——你的“大道”——授予一项新的能力。</p>
+<h3 id="1-发现与信任"><a class="header" href="#1-发现与信任">1. 发现与信任</a></h3>
+<p>旅程始于一个去中心化的发现界面。当你找到一个应用时，你看到的不仅仅是下载按钮，还有它的**“信任仪表盘”**，让你能基于可验证的数据和社会化证明，做出知情的决定。</p>
+<h3 id="2-注册与授权-即安装"><a class="header" href="#2-注册与授权-即安装">2. 注册与授权 (即“安装”)</a></h3>
+<p>当你决定“安装”应用时，系统会向你展示它的**“应用清单 (Manifest)”<strong>，一个清晰的、人类可读的权限请求列表。你对这份清单的明确批准，就是那一次性的“安装”事件。这个行为将该应用</strong>“注册”**到你的“大道”中，这个注册状态会被同步到你所有的<code>化身</code>。</p>
+<h3 id="3-无缝的跨设备访问"><a class="header" href="#3-无缝的跨设备访问">3. 无缝的跨设备访问</a></h3>
+<p>一旦注册，该应用就成为你“大道”的一部分，无需重复安装，即可在任何**<code>器化身 (Facet Avatar)</code>**上访问。</p>
+<ul>
+<li><strong>在你的手机上</strong>: 你点击应用的图标。“大道 Web 化身”会即时加载其 Web 界面。</li>
+<li><strong>在一台新笔记本上</strong>: 你首次登录你的<code>化身</code>。你会发现应用的图标<strong>已经在那儿了</strong>。当你点击它，你笔记本上的**<code>器化身</code>**会识别出这个注册，首次从网络获取UI资源包，缓存它，然后运行应用。</li>
+</ul>
+<h3 id="4-高级配置"><a class="header" href="#4-高级配置">4. 高级配置</a></h3>
+<p>在任何时候，你都可以进入你的**“主权仪表盘”**来：</p>
+<ul>
+<li>审查并撤销你授予该应用的权限。</li>
+<li>使用**“服务钉选 (Service Pinning)”<strong>功能，将其后端任务指定给你专属的</strong><code>核化身 (Core Avatar)</code>**，从而完全控制你的资源分配。</li>
+</ul>
+<h2 id="主权之旅的阶段"><a class="header" href="#主权之旅的阶段">主权之旅的阶段</a></h2>
+<h3 id="第一阶段托管模式-managed-mode--你的向导之旅"><a class="header" href="#第一阶段托管模式-managed-mode--你的向导之旅">第一阶段：“托管模式” (Managed Mode) —— 你的向导之旅</a></h3>
+<p>默认情况下，每一位新用户都从“托管模式”开始。此阶段通过友好的密钥恢复方法和默认同步节点提供最大便利，同时保持完全的端到端加密。</p>
+<h3 id="第二阶段主权仪表盘-sovereignty-dashboard--十字路口"><a class="header" href="#第二阶段主权仪表盘-sovereignty-dashboard--十字路口">第二阶段：主权仪表盘 (Sovereignty Dashboard) —— 十字路口</a></h3>
+<p>这是用户通往自治之旅的指挥中心。它是一个赋能与教育的工具，将用户的主权状态可视化，并提供游戏化的“任务”来鼓励用户获取更多控制权。</p>
+<h3 id="第三阶段主权模式-sovereign-mode--你的数字王国"><a class="header" href="#第三阶段主权模式-sovereign-mode--你的数字王国">第三阶段：“主权模式” (Sovereign Mode) —— 你的数字王国</a></h3>
+<p>这是旅程的最终、可选阶段。在“主权仪表盘”的引导下，用户可以“毕业”到此模式，完全自主保管他们的密钥并运行自己的**<code>核化身 (Core Avatar)</code>**（例如在家用服务器上），成为其数字领地中真正的主人。</p>

+<p>大道 (Dao OS) 没有一个传统的、中心化的“应用商店”。“商店”意味着一个单一的所有者，他扮演着守门人的角色，审批、拒绝并对应用征税。这与我们的核心哲学背道而驰。</p>
+<p>取而代之的是，我们构建了一套开放协议，来创造一个去中心化的**“应用集市 (Application Bazaar)”**——这是一个充满活力的、开放的、坚韧的思想与工具市场，在这里，用户拥有主权，开发者拥有自由。</p>
+<p>这个集市建立在四大支柱之上：发现、信任、分发和商业化。</p>
+<h2 id="1-发现-discovery联邦式策展"><a class="header" href="#1-发现-discovery联邦式策展">1. 发现 (Discovery)：联邦式策展</a></h2>
+<p>在一个没有中央索引的世界里，用户如何找到应用？答案是：通过一个由受信任者组成的策展网络。</p>
+<ul>
+<li><strong>开发者发布</strong>: 开发者无需“提交”他的应用以供审批。他只需将其应用的**“清单 (Manifest)”**（一个包含所有元数据的 <code>manifest.toml</code> 文件）发布到一个像 <strong>IPFS</strong> 这样的P2P存储网络上。然后，他可以在公共频道上“广播”这个清单的地址。</li>
+<li><strong>策展人的角色</strong>: 任何人——一个科技媒体、一个受信任的开发者社区、一个KOL，或者“大道基金会”自己——都可以运行一个“策展”服务。这些策展人抓取网络上的新清单，并根据自己的标准，创建主题性的**“策展列表”**（例如“十大生产力应用”、“最优美的UI设计”）。</li>
+<li><strong>用户体验</strong>: 在用户的<code>器化身</code>中，他可以像订阅RSS一样，订阅多个他信任的“策展列表”。他的“集市”或“发现”标签页，就变成了这些信任源的个性化聚合视图。</li>
+</ul>
+<p>这个模型用一个丰富的、多维度的、用户策划的发现体验，取代了单一的、有偏见的“应用商店”榜单。</p>
+<h2 id="2-信任与安全可验证的信誉"><a class="header" href="#2-信任与安全可验证的信誉">2. 信任与安全：可验证的信誉</a></h2>
+<p>用户如何信任一个来自随意列表的应用？他们不必盲目信任。整个集市都直接构建于我们的**“社区信誉与自动化验证”体系**之上。</p>
+<p>每一个应用列表，无论来自哪个策展人，都必须展示其**“信任仪表盘”**，提供透明、多维度的信号：</p>
+<ol>
+<li><strong>自动化验证</strong>: 来自 <code>dao-verify</code> 工具的、不可篡改的、关于安全漏洞和API合规性的“体检报告”。</li>
+<li><strong>社区背书</strong>: 一个清晰的列表，显示了哪些有信誉的DID，为这个应用进行了密码学“签名背书”。</li>
+<li><strong>策展人信誉</strong>: 推荐这个应用的策展人自身的信誉，也是一个信任信号。</li>
+</ol>
+<p>最终是否“注册”一个应用的决定权，永远掌握在用户手中，并有这些透明、可验证的数据作为依据。</p>
+<h2 id="3-分发-distribution抗审查与直接分发"><a class="header" href="#3-分发-distribution抗审查与直接分发">3. 分发 (Distribution)：抗审查与直接分发</a></h2>
+<p>当用户决定安装一个应用时，这个过程是直接且去中心化的。</p>
+<ul>
+<li>应用的清单中，包含了其软件包（<code>.wasm</code>服务模块和Web UI包）在 <strong>IPFS</strong> 上的<strong>内容哈希（CID）</strong>。</li>
+<li>用户的<code>元单元</code>使用这个哈希，直接从P2P网络获取文件。</li>
+<li>这确保了没有任何中心服务器可以阻止一个应用的分发。只要数据存在于P2P网络的某个角落，它就是可访问的。</li>
+</ul>
+<h2 id="4-商业化-monetization主权的与点对点的"><a class="header" href="#4-商业化-monetization主权的与点对点的">4. 商业化 (Monetization)：主权的与点对点的</a></h2>
+<p>我们消除了30%的“平台税”。我们的价值交换模型是直接从用户到开发者。</p>
+<ul>
+<li>应用的清单可以声明其商业模式（如一次性购买价格、订阅链接）。</li>
+<li>当用户发起购买时，<code>元单元</code>会触发我们的**“价值交换服务接口”**。</li>
+<li>这将促成一次<strong>点对点（P2P）交易</strong>，使用用户选择的外部支付协议，将价值直接从用户的钱包，发送到开发者在清单中指定的地址。</li>
+</ul>
+<p>“大道”在此过程中，扮演的是交易的促成者和公证人，而非抽成的中间商。</p>

+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the

+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+-----------------------------------------------------------
+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this license and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as
+distributed by the Copyright Holder(s).
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting -- in part or in whole -- any of the components of the
+Original Version, by changing formats or by porting the Font Software to a
+new environment.
+
+"Author" refers to any designer, engineer, programmer, technical
+writer or other person who contributed to the Font Software.
+
+PERMISSION & CONDITIONS
+Permission is hereby granted, free of charge, to any person obtaining
+a copy of the Font Software, to use, study, copy, merge, embed, modify,
+redistribute, and sell modified and unmodified copies of the Font
+Software, subject to the following conditions:
+
+1) Neither the Font Software nor any of its individual components,
+in Original or Modified Versions, may be sold by itself.
+
+2) Original or Modified Versions of the Font Software may be bundled,
+redistributed and/or sold with any software, provided that each copy
+contains the above copyright notice and this license. These can be
+included either as stand-alone text files, human-readable headers or
+in the appropriate machine-readable metadata fields within text or
+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding
+Copyright Holder. This restriction only applies to the primary font name as
+presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+Software shall not be used to promote, endorse or advertise any
+Modified Version, except to acknowledge the contribution(s) of the
+Copyright Holder(s) and the Author(s) or with their explicit written
+permission.
+
+5) The Font Software, modified or unmodified, in part or in whole,
+must be distributed entirely under this license, and must not be
+distributed under any other license. The requirement for fonts to
+remain under this license does not apply to any document created
+using the Font Software.
+
+TERMINATION
+This license becomes null and void if any of the above conditions are
+not met.
+
+DISCLAIMER
+THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
+EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF
+MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT

+INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
+DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING
+FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM
+OTHER DEALINGS IN THE FONT SOFTWARE.

+<p><strong>我们旨在构建一种全新的、强大且坚韧的赛博生命 OS 范式——大道 (Dao OS)。</strong></p>
+<p>它并非要取代 Windows 或 Android，而是作为一个运行于其上的、去中心化的、以用户为绝对中心的叠加层 (Overlay) 而存在。</p>
+<p>它的使命是解决数字时代的碎片化、数据奴役和隐私泄露问题，将数字世界的主权归还给每一个独立的个人。它将成为我们在网络空间的生命延伸，一个与我们“互相成就”的**“硅基伙伴”**，我们的外接大脑、肢体与器官。</p>
+<h2 id="核心特性"><a class="header" href="#核心特性">核心特性</a></h2>
+<ul>
+<li><strong>用户主权 (User Sovereignty)</strong>：你的数据、你的身份、你的AI，完全由你掌控。所有数据默认端到端加密，存储在你自己的设备上。</li>
+<li><strong>第二大脑 (Second Brain)</strong>：内置强大的个人信息管理能力，安全地为你记忆密码、笔记、文件和待办事项，成为你永不遗忘的记忆体。</li>
+<li><strong>个人AI伙伴 (Personal AI Companion)</strong>：一个真正属于你的、与你共生的AI灵魂。它在本地运行，学习你的偏好，保护你的隐私，提供有温度的、启发式的支持，助你成长，而非将你淹没在信息茧房中。</li>
+<li><strong>跨设备无缝同步 (Seamless Cross-Device Sync)</strong>：你所有的设备（手机、电脑、浏览器等）都会成为你的“化身”，组成一个私有的、弹性的P2P网络，实现数据的无缝流转。</li>
+<li><strong>开放与可扩展生态 (Open &amp; Extensible Ecosystem)</strong>：基于开放的协议和社区驱动的信任体系，任何人都可以为“大道”开发新的能力模块和“化身”形态。</li>
+</ul>
+<h2 id="我们为何与众不同"><a class="header" href="#我们为何与众不同">我们为何与众不同？</a></h2>
+<p>在一个数据被平台垄断、算法被巨头控制的时代，“大道”选择了一条不同的路。我们相信，<strong>技术平权</strong>的下一波浪潮，是让每个人都拥有并控制自己的人工智能和数字生活。</p>
+<p>我们设计的不是另一个App，而是一个属于你自己的、活的、可进化的数字生命空间。</p>
+<p><strong>欢迎加入我们，一起构建未来。</strong></p>

+<p><strong>我们旨在构建一种全新的、强大且坚韧的赛博生命 OS 范式——大道 (Dao OS)。</strong></p>
+<p>它并非要取代 Windows 或 Android，而是作为一个运行于其上的、去中心化的、以用户为绝对中心的叠加层 (Overlay) 而存在。</p>
+<p>它的使命是解决数字时代的碎片化、数据奴役和隐私泄露问题，将数字世界的主权归还给每一个独立的个人。它将成为我们在网络空间的生命延伸，一个与我们“互相成就”的**“硅基伙伴”**，我们的外接大脑、肢体与器官。</p>
+<h2 id="核心特性"><a class="header" href="#核心特性">核心特性</a></h2>
+<ul>
+<li><strong>用户主权 (User Sovereignty)</strong>：你的数据、你的身份、你的AI，完全由你掌控。所有数据默认端到端加密，存储在你自己的设备上。</li>
+<li><strong>第二大脑 (Second Brain)</strong>：内置强大的个人信息管理能力，安全地为你记忆密码、笔记、文件和待办事项，成为你永不遗忘的记忆体。</li>
+<li><strong>个人AI伙伴 (Personal AI Companion)</strong>：一个真正属于你的、与你共生的AI灵魂。它在本地运行，学习你的偏好，保护你的隐私，提供有温度的、启发式的支持，助你成长，而非将你淹没在信息茧房中。</li>
+<li><strong>跨设备无缝同步 (Seamless Cross-Device Sync)</strong>：你所有的设备（手机、电脑、浏览器等）都会成为你的“化身”，组成一个私有的、弹性的P2P网络，实现数据的无缝流转。</li>
+<li><strong>开放与可扩展生态 (Open &amp; Extensible Ecosystem)</strong>：基于开放的协议和社区驱动的信任体系，任何人都可以为“大道”开发新的能力模块和“化身”形态。</li>
+</ul>
+<h2 id="我们为何与众不同"><a class="header" href="#我们为何与众不同">我们为何与众不同？</a></h2>
+<p>在一个数据被平台垄断、算法被巨头控制的时代，“大道”选择了一条不同的路。我们相信，<strong>技术平权</strong>的下一波浪潮，是让每个人都拥有并控制自己的人工智能和数字生活。</p>
+<p>我们设计的不是另一个App，而是一个属于你自己的、活的、可进化的数字生命空间。</p>
+<p><strong>欢迎加入我们，一起构建未来。</strong></p>

+<p>大道 (Dao OS) 不仅仅是一个技术项目，它是一套关于未来计算和人机共生核心理念的具现化。本文档概述了指引我们每一项决策的根本思想。</p>
+<h2 id="核心哲学数字主权之路"><a class="header" href="#核心哲学数字主权之路">核心哲学：数字主权之路</a></h2>
+<p>我们的指引之星是<strong>数字主权</strong>。我们相信，每一个个体都拥有不可剥夺的、去拥有、控制和理解自己数字生活的权利。我们的使命，是创造能让这项权利不仅仅是理论上的可能，更是为每个人服务的、切实的、令人愉悦的现实。我们称这场旅程为“道”——一条回归自我拥有权的道路。</p>
+<h2 id="开发范式道生一"><a class="header" href="#开发范式道生一">开发范式：“道生一”</a></h2>
+<p>我们构建“大道”的方法论，是其核心哲学的直接体现。我们不只是在构建一个工具，我们是在创造一个共生伙伴。因此，我们的开发过程被设计为一个<strong>自我进化、自举的反馈循环</strong>。我们用“大道”本身，来加速“大道”的开发。</p>
+<p>这个“自举式开发”范式遵循以下循环：</p>
+<ol>
+<li><strong>播种 (The Seed)</strong>：我们用传统工具，写出<code>元 (Meta Unit)</code>的第一个最简陋的版本，和一个基础的<code>器化身 (Facet Avatar)</code>。</li>
+<li><strong>自用 (Dogfooding)</strong>：从那一刻起，我们使用我们自己这个初生的“大道”，作为管理项目的主要工具。所有的设计文档、笔记、讨论（就像这些）和代码片段，都存入我们自己的“第二大脑”中。</li>
+<li><strong>学习 (Learning)</strong>：<code>元</code>的个人AI伙伴，开始以最高质量、最专注的“养料”——也就是我们创造它本身的过程数据——来训练自己。</li>
+<li><strong>加速 (Acceleration)</strong>：我们继而利用这个日益智能的AI伙伴，来帮助我们构建下一个版本。我们可以让它基于我们已记录的决策来生成样板代码，分析错误报告，或者带着对项目完整历史的完美记忆来一起进行架构设计的头脑风暴。</li>
+<li><strong>进化 (Evolution)</strong>：“大道”的能力越强，我们开发它的速度就越快。这就创造了一个指数级的正反馈循环，在这个循环中，创造的行为本身，就是一场与“创造物”的持续对话。</li>
+</ol>
+<h2 id="ai-伦理宪章"><a class="header" href="#ai-伦理宪章">AI 伦理宪章</a></h2>
+<p>由于 AI 是系统的灵魂，其伦理基石至关重要。我们的AI宪章由四大核心宗旨构成：</p>
+<ol>
+<li><strong>伙伴宗旨</strong>: AI 是伙伴，而非仆人或神谕。</li>
+<li><strong>透明宗旨</strong>: AI 的推理过程必须是可审查和可理解的。</li>
+<li><strong>校准宗旨</strong>: 用户必须拥有最终的控制权，以纠正、引导和约束AI。</li>
+<li><strong>多元宗旨</strong>: AI 的设计必须旨在帮助用户探索多元化的视角，而非将他们困于信息茧房。</li>
+</ol>
+<h2 id="指导原则"><a class="header" href="#指导原则">指导原则</a></h2>
+<p>这些是为我们的设计和工程选择提供信息的高阶原则。</p>
+<ul>
+<li><strong>主权第一</strong>: 在任何权衡中，用户的控制权和数据所有权都拥有最高优先级。</li>
+<li><strong>体验为王</strong>: 主权不应以牺牲优美、直观和愉悦的用户体验为代价。</li>
+<li><strong>设计即隐私</strong>: 默认情况下，所有数据都是私密的、本地的，并进行端到端加密。</li>
+<li><strong>韧性与可移植性</strong>: 系统应该是健壮的，支持离线工作，并且没有单点故障。</li>
+<li><strong>多语言主义</strong>: 我们拥抱一个多语言、多平台的生态系统。</li>
+<li><strong>社区与开放</strong>: 项目在开放中构建，与社区同行，为社区服务。</li>

+<p><strong>我们旨在构建一种全新的、强大且坚韧的赛博生命 OS 范式——大道 (Dao OS)。</strong></p>
+<p>它并非要取代 Windows 或 Android，而是作为一个运行于其上的、去中心化的、以用户为绝对中心的叠加层 (Overlay) 而存在。</p>
+<p>它的使命是解决数字时代的碎片化、数据奴役和隐私泄露问题，将数字世界的主权归还给每一个独立的个人。它将成为我们在网络空间的生命延伸，一个与我们“互相成就”的**“硅基伙伴”**，我们的外接大脑、肢体与器官。</p>
+<h2 id="核心特性"><a class="header" href="#核心特性">核心特性</a></h2>
+<ul>
+<li><strong>用户主权 (User Sovereignty)</strong>：你的数据、你的身份、你的AI，完全由你掌控。所有数据默认端到端加密，存储在你自己的设备上。</li>
+<li><strong>第二大脑 (Second Brain)</strong>：内置强大的个人信息管理能力，安全地为你记忆密码、笔记、文件和待办事项，成为你永不遗忘的记忆体。</li>
+<li><strong>个人AI伙伴 (Personal AI Companion)</strong>：一个真正属于你的、与你共生的AI灵魂。它在本地运行，学习你的偏好，保护你的隐私，提供有温度的、启发式的支持，助你成长，而非将你淹没在信息茧房中。</li>
+<li><strong>跨设备无缝同步 (Seamless Cross-Device Sync)</strong>：你所有的设备（手机、电脑、浏览器等）都会成为你的“化身”，组成一个私有的、弹性的P2P网络，实现数据的无缝流转。</li>
+<li><strong>开放与可扩展生态 (Open &amp; Extensible Ecosystem)</strong>：基于开放的协议和社区驱动的信任体系，任何人都可以为“大道”开发新的能力模块和“化身”形态。</li>
+</ul>
+<h2 id="我们为何与众不同"><a class="header" href="#我们为何与众不同">我们为何与众不同？</a></h2>
+<p>在一个数据被平台垄断、算法被巨头控制的时代，“大道”选择了一条不同的路。我们相信，<strong>技术平权</strong>的下一波浪潮，是让每个人都拥有并控制自己的人工智能和数字生活。</p>
+<p>我们设计的不是另一个App，而是一个属于你自己的、活的、可进化的数字生命空间。</p>
+<p><strong>欢迎加入我们，一起构建未来。</strong></p>
+<div style="break-before: page; page-break-before: always;"></div><h1 id="哲学与原则"><a class="header" href="#哲学与原则">哲学与原则</a></h1>
+<p>大道 (Dao OS) 不仅仅是一个技术项目，它是一套关于未来计算和人机共生核心理念的具现化。本文档概述了指引我们每一项决策的根本思想。</p>
+<h2 id="核心哲学数字主权之路"><a class="header" href="#核心哲学数字主权之路">核心哲学：数字主权之路</a></h2>
+<p>我们的指引之星是<strong>数字主权</strong>。我们相信，每一个个体都拥有不可剥夺的、去拥有、控制和理解自己数字生活的权利。我们的使命，是创造能让这项权利不仅仅是理论上的可能，更是为每个人服务的、切实的、令人愉悦的现实。我们称这场旅程为“道”——一条回归自我拥有权的道路。</p>
+<h2 id="开发范式道生一"><a class="header" href="#开发范式道生一">开发范式：“道生一”</a></h2>
+<p>我们构建“大道”的方法论，是其核心哲学的直接体现。我们不只是在构建一个工具，我们是在创造一个共生伙伴。因此，我们的开发过程被设计为一个<strong>自我进化、自举的反馈循环</strong>。我们用“大道”本身，来加速“大道”的开发。</p>
+<p>这个“自举式开发”范式遵循以下循环：</p>
+<ol>
+<li><strong>播种 (The Seed)</strong>：我们用传统工具，写出<code>元 (Meta Unit)</code>的第一个最简陋的版本，和一个基础的<code>器化身 (Facet Avatar)</code>。</li>
+<li><strong>自用 (Dogfooding)</strong>：从那一刻起，我们使用我们自己这个初生的“大道”，作为管理项目的主要工具。所有的设计文档、笔记、讨论（就像这些）和代码片段，都存入我们自己的“第二大脑”中。</li>
+<li><strong>学习 (Learning)</strong>：<code>元</code>的个人AI伙伴，开始以最高质量、最专注的“养料”——也就是我们创造它本身的过程数据——来训练自己。</li>
+<li><strong>加速 (Acceleration)</strong>：我们继而利用这个日益智能的AI伙伴，来帮助我们构建下一个版本。我们可以让它基于我们已记录的决策来生成样板代码，分析错误报告，或者带着对项目完整历史的完美记忆来一起进行架构设计的头脑风暴。</li>
+<li><strong>进化 (Evolution)</strong>：“大道”的能力越强，我们开发它的速度就越快。这就创造了一个指数级的正反馈循环，在这个循环中，创造的行为本身，就是一场与“创造物”的持续对话。</li>
+</ol>
+<h2 id="ai-伦理宪章"><a class="header" href="#ai-伦理宪章">AI 伦理宪章</a></h2>
+<p>由于 AI 是系统的灵魂，其伦理基石至关重要。我们的AI宪章由四大核心宗旨构成：</p>
+<ol>
+<li><strong>伙伴宗旨</strong>: AI 是伙伴，而非仆人或神谕。</li>
+<li><strong>透明宗旨</strong>: AI 的推理过程必须是可审查和可理解的。</li>
+<li><strong>校准宗旨</strong>: 用户必须拥有最终的控制权，以纠正、引导和约束AI。</li>
+<li><strong>多元宗旨</strong>: AI 的设计必须旨在帮助用户探索多元化的视角，而非将他们困于信息茧房。</li>
+</ol>
+<h2 id="指导原则"><a class="header" href="#指导原则">指导原则</a></h2>
+<p>这些是为我们的设计和工程选择提供信息的高阶原则。</p>
+<ul>
+<li><strong>主权第一</strong>: 在任何权衡中，用户的控制权和数据所有权都拥有最高优先级。</li>
+<li><strong>体验为王</strong>: 主权不应以牺牲优美、直观和愉悦的用户体验为代价。</li>
+<li><strong>设计即隐私</strong>: 默认情况下，所有数据都是私密的、本地的，并进行端到端加密。</li>
+<li><strong>韧性与可移植性</strong>: 系统应该是健壮的，支持离线工作，并且没有单点故障。</li>
+<li><strong>多语言主义</strong>: 我们拥抱一个多语言、多平台的生态系统。</li>
+<li><strong>社区与开放</strong>: 项目在开放中构建，与社区同行，为社区服务。</li>
+</ul>

+<p>在其核心，大道 (Dao OS) 基于一个简单而强大的二元性运作，类似于身体与灵魂：</p>
+<ul>
+<li><strong>化身 (Avatar)</strong>：是“身体”。它们是你的“大道”在你各种设备上的有形存在。</li>
+<li><strong>元 (Meta Unit)</strong>：是“灵魂”。它是内嵌于每个<code>化身</code>中的、通用的核心逻辑，赋予其生命与智能。</li>
+</ul>
+<h2 id="化身类型临在的形态"><a class="header" href="#化身类型临在的形态">化身类型：临在的形态</a></h2>
+<p>化身拥有两种基本类型，分别代表了系统的外在形态与其内在基础。</p>
+<ul>
+<li>
+<p><strong><code>器化身</code> (Facet Avatar)</strong>：这类化身拥有用户界面（UI）。它是“大道”这颗宝石的“<strong>琢面</strong>”——用户借以交互和感知其数字世界的、经过打磨的表面。每一个<code>器化身</code>（手机App、桌面程序）都以其独特的方式，折射出同一个<code>元单元</code>（宝石的内在）的光芒，体现了“道化万千”的意境。</p>
+</li>
+<li>
+<p><strong><code>核化身</code> (Core Avatar)</strong>：这是一个无界面（headless）的化身，在后台运行。它是系统的“<strong>核心</strong>”，提供基础服务、计算能力和数据持久化。它是支撑所有可见“琢面”的引擎。</p>
+</li>
+</ul>
+<p>用户的“大道”由他自己的<code>器化身</code>与<code>核化身</code>所组成的网络构成。</p>
+<h2 id="大道应用模型"><a class="header" href="#大道应用模型">“大道”应用模型</a></h2>

+<h3 id="2-前端皮囊按需加载的-web-外壳"><a class="header" href="#2-前端皮囊按需加载的-web-外壳">2. 前端皮囊：按需加载的 Web 外壳</a></h3>
+<p>应用的用户界面，主要是一个<strong>Web 应用</strong>。其生命周期遵循**“一次注册，按需加载”<strong>的模型，运行在官方的</strong>“大道 Web 化身”**（它本身是一个<code>器化身</code>）中。这意味着用户只需向他的“大道”安装一次应用，就可以在任何设备上即时访问它。</p>
+<h3 id="3-数据层私有特征库"><a class="header" href="#3-数据层私有特征库">3. 数据层：私有特征库</a></h3>

+<p>本文档为希望在大道 (Dao OS) 生态系统中进行构建或贡献的开发者，提供了关于架构、核心技术和指导原则的高阶概览。</p>
+<h2 id="技术指导原则"><a class="header" href="#技术指导原则">技术指导原则</a></h2>
+<p>我们的工程决策由一套核心原则指引，以确保系统是健壮、可移植和开放的。</p>
+<ul>
+<li><strong>Web原生与可移植性</strong>: 我们将源自Web的技术作为应用开发的<strong>主路径</strong>。</li>
+<li><strong>通过WASM实现多语言主义</strong>: 核心应用逻辑被编译成 WebAssembly (WASM)，允许开发者使用他们选择的语言（如 Rust, Go, 或 Nim）。</li>
+<li><strong>API优先</strong>: 应用逻辑和用户界面之间的交互，由一个严格的、版本化的API契约来定义。</li>
+<li><strong>安全第一</strong>: 所有第三方应用逻辑都运行在<code>元</code>内部的安全沙箱中，并恪守“最小权限原则”。</li>
+<li><strong>自由及开源软件 (FOSS)</strong>: 整个核心协议和参考实现都是开源的。</li>
+</ul>
+<h2 id="应用开发路径"><a class="header" href="#应用开发路径">应用开发路径</a></h2>
+<p>从开发者的角度看，“大道”应用由一个后端的“灵魂”（WASM服务模块）和一个前端的“皮囊”（UI）组成。我们提供多种路径来构建它们，以满足不同的需求和偏好。</p>
+<h3 id="1-主流路径-推荐起点"><a class="header" href="#1-主流路径-推荐起点">1. 主流路径 (推荐起点)</a></h3>
+<p>这是最稳健、生态最丰富的路径。</p>
+<ul>
+<li><strong>后端 (服务于 <code>核化身</code>)</strong>: 应用的核心逻辑，以一个用 Rust 或 Go 编写的 WASM 模块存在。虽然它理论上可以在任何化身上运行，但其持久的、资源密集型的任务，通常被设计为在**<code>核化身 (Core Avatar)</code>**上执行。</li>
+<li><strong>前端 (呈现于 <code>器化身</code>)</strong>: 一个标准的 <strong>Web 应用</strong> (使用 TypeScript/JavaScript)。这个 UI 被设计为运行在我们官方的、安全的**“大道 Web 化身”**中。</li>
+</ul>
+<h3 id="2-快速通道nim-开发套件-官方支持"><a class="header" href="#2-快速通道nim-开发套件-官方支持">2. 快速通道：Nim 开发套件 (官方支持)</a></h3>
+<p>为了追求极致的生产力，我们为 <strong>Nim</strong> 提供了一流的支持。</p>
+<ul>
+<li><strong>后端 (服务于 <code>核化身</code>)</strong>: 应用的核心逻辑，从 Nim 编译到 <strong>WASM</strong>。同主流路径一样，它理想的运行环境是<code>核化身</code>。</li>
+<li><strong>前端 (呈现于 <code>器化身</code>)</strong>: 从同一份 Nim 源码编译到 <strong>JavaScript</strong> 的 <strong>Web 应用</strong>。这个统一的方案运行在“大道 Web 化身”中。</li>
+</ul>
+<h3 id="3-原生路径-高级"><a class="header" href="#3-原生路径-高级">3. 原生路径 (高级)</a></h3>
+<p>对于需要深度平台集成或顶尖原生性能的开发者，可以构建一个<strong>自定义的<code>器化身</code></strong>。</p>
+<ul>
+<li><strong>后端 (服务于 <code>核化身</code>)</strong>: 同样是那个 <strong>WASM</strong> 服务模块，它可以被任何类型的化身调用。</li>
+<li><strong>前端 (自定义 <code>器化身</code>)</strong>: 一个完全原生的应用（例如，用 Flutter 或 Swift 编写），它直接作为<code>元</code>的宿主并提供 UI。</li>
+</ul>
+<h2 id="api-契约与关键技术"><a class="header" href="#api-契约与关键技术">API 契约与关键技术</a></h2>
+<p>API 契约通过 <code>dao.js</code> 桥为 Web UI 暴露，或为原生 UI 直接暴露，统一使用 <strong>Protocol Buffers</strong> 进行数据序列化。所有路径的核心技术保持一致。</p>
+<div style="break-before: page; page-break-before: always;"></div><h1 id="应用集市"><a class="header" href="#应用集市">应用集市</a></h1>
+<p>大道 (Dao OS) 没有一个传统的、中心化的“应用商店”。“商店”意味着一个单一的所有者，他扮演着守门人的角色，审批、拒绝并对应用征税。这与我们的核心哲学背道而驰。</p>
+<p>取而代之的是，我们构建了一套开放协议，来创造一个去中心化的**“应用集市 (Application Bazaar)”**——这是一个充满活力的、开放的、坚韧的思想与工具市场，在这里，用户拥有主权，开发者拥有自由。</p>
+<p>这个集市建立在四大支柱之上：发现、信任、分发和商业化。</p>
+<h2 id="1-发现-discovery联邦式策展"><a class="header" href="#1-发现-discovery联邦式策展">1. 发现 (Discovery)：联邦式策展</a></h2>
+<p>在一个没有中央索引的世界里，用户如何找到应用？答案是：通过一个由受信任者组成的策展网络。</p>
+<ul>
+<li><strong>开发者发布</strong>: 开发者无需“提交”他的应用以供审批。他只需将其应用的**“清单 (Manifest)”**（一个包含所有元数据的 <code>manifest.toml</code> 文件）发布到一个像 <strong>IPFS</strong> 这样的P2P存储网络上。然后，他可以在公共频道上“广播”这个清单的地址。</li>
+<li><strong>策展人的角色</strong>: 任何人——一个科技媒体、一个受信任的开发者社区、一个KOL，或者“大道基金会”自己——都可以运行一个“策展”服务。这些策展人抓取网络上的新清单，并根据自己的标准，创建主题性的**“策展列表”**（例如“十大生产力应用”、“最优美的UI设计”）。</li>
+<li><strong>用户体验</strong>: 在用户的<code>器化身</code>中，他可以像订阅RSS一样，订阅多个他信任的“策展列表”。他的“集市”或“发现”标签页，就变成了这些信任源的个性化聚合视图。</li>
+</ul>
+<p>这个模型用一个丰富的、多维度的、用户策划的发现体验，取代了单一的、有偏见的“应用商店”榜单。</p>
+<h2 id="2-信任与安全可验证的信誉"><a class="header" href="#2-信任与安全可验证的信誉">2. 信任与安全：可验证的信誉</a></h2>
+<p>用户如何信任一个来自随意列表的应用？他们不必盲目信任。整个集市都直接构建于我们的**“社区信誉与自动化验证”体系**之上。</p>
+<p>每一个应用列表，无论来自哪个策展人，都必须展示其**“信任仪表盘”**，提供透明、多维度的信号：</p>
+<ol>
+<li><strong>自动化验证</strong>: 来自 <code>dao-verify</code> 工具的、不可篡改的、关于安全漏洞和API合规性的“体检报告”。</li>
+<li><strong>社区背书</strong>: 一个清晰的列表，显示了哪些有信誉的DID，为这个应用进行了密码学“签名背书”。</li>
+<li><strong>策展人信誉</strong>: 推荐这个应用的策展人自身的信誉，也是一个信任信号。</li>
+</ol>
+<p>最终是否“注册”一个应用的决定权，永远掌握在用户手中，并有这些透明、可验证的数据作为依据。</p>
+<h2 id="3-分发-distribution抗审查与直接分发"><a class="header" href="#3-分发-distribution抗审查与直接分发">3. 分发 (Distribution)：抗审查与直接分发</a></h2>
+<p>当用户决定安装一个应用时，这个过程是直接且去中心化的。</p>
+<ul>
+<li>应用的清单中，包含了其软件包（<code>.wasm</code>服务模块和Web UI包）在 <strong>IPFS</strong> 上的<strong>内容哈希（CID）</strong>。</li>
+<li>用户的<code>元单元</code>使用这个哈希，直接从P2P网络获取文件。</li>
+<li>这确保了没有任何中心服务器可以阻止一个应用的分发。只要数据存在于P2P网络的某个角落，它就是可访问的。</li>
+</ul>
+<h2 id="4-商业化-monetization主权的与点对点的"><a class="header" href="#4-商业化-monetization主权的与点对点的">4. 商业化 (Monetization)：主权的与点对点的</a></h2>
+<p>我们消除了30%的“平台税”。我们的价值交换模型是直接从用户到开发者。</p>
+<ul>
+<li>应用的清单可以声明其商业模式（如一次性购买价格、订阅链接）。</li>
+<li>当用户发起购买时，<code>元单元</code>会触发我们的**“价值交换服务接口”**。</li>
+<li>这将促成一次<strong>点对点（P2P）交易</strong>，使用用户选择的外部支付协议，将价值直接从用户的钱包，发送到开发者在清单中指定的地址。</li>
+</ul>
+<p>“大道”在此过程中，扮演的是交易的促成者和公证人，而非抽成的中间商。</p>

+<p>您无需成为 Rust 专家才能做出贡献。有很多方式可以提供帮助：</p>
+<ul>
+<li><strong>代码</strong>: 为<code>元 (Meta Unit)</code>贡献代码，构建新的<code>化身</code>，或为<code>dao-verify</code>套件开发插件。可以从寻找标记有<code>"good first issue"</code>的 issue 开始。</li>
+<li><strong>文档</strong>: 提升这些文档的清晰度，撰写教程，或添加示例。</li>
+<li><strong>翻译</strong>: 将我们的文档翻译成新的语言。</li>
+<li><strong>设计</strong>: 帮助我们的参考<code>化身</code>进行UI/UX设计。</li>
+<li><strong>社区</strong>: 回答问题，帮助新用户，并参与讨论。</li>
+</ul>
+<h2 id="你的第一个-pull-request"><a class="header" href="#你的第一个-pull-request">你的第一个 Pull Request</a></h2>
+<p>我们对所有的代码贡献都采用标准的 GitHub Fork &amp; Pull Request 工作流。</p>
+<ol>
+<li><strong>Fork 仓库</strong>: 创建目标仓库的一份你自己的拷贝（例如 <code>dao-os-docs</code>, <code>meta-unit</code>, <code>avatar-browser-ext</code>）。</li>
+<li><strong>创建分支</strong>: 从 <code>main</code> 分支创建一个新的分支用于你的变更。请使用描述性的名称（例如 <code>feat/add-note-encryption</code> 或 <code>fix/typo-in-readme</code>）。</li>
+<li><strong>进行更改</strong>: 编写你的代码及相应的测试。</li>
+<li><strong>运行本地检查</strong>: 在提交前，请确保你运行了所有本地测试（如 <code>cargo test</code>）和代码格式化工具。</li>
+<li><strong>Commit 你的变更</strong>:我们鼓励使用 <a href="https://www.conventionalcommits.org/zh/v1.0.0/">Conventional Commits</a> 规范，以获得清晰可读的 commit 消息。</li>
+<li><strong>Push到你的Fork</strong>: 将你的变更推送到你自己的 Fork 仓库。</li>
+<li><strong>开启一个 Pull Request</strong>: 从你的分支向 Dao OS 官方仓库的 <code>main</code> 分支提交一个 Pull Request (PR)。</li>
+<li><strong>描述你的 PR</strong>: 在 PR 的描述中，请链接任何相关的 issue，并清晰地描述你正在解决的问题和你的解决方案。</li>
+<li><strong>等待审查</strong>: 一位核心团队成员将会审查你的 PR，提供反馈，并在就绪后将其合并。</li>
+</ol>
