 ## Core Principles
 
 ### I. Semantic Protocol Compliance
-The file `semantic_protocol.md` is the **authoritative technical standard** for this project. All code generation, refactoring, and architecture must strictly adhere to the standards, syntax, and workflows defined therein.
-- **Syntax**: `[DEF]` anchors, `@RELATION` tags, and metadata must match the Protocol specification.
-- **Structure**: File layouts and headers must follow the "File Structure Standard".
-- **Workflow**: The technical steps for generating code must align with the Protocol.
+The file `semantic_protocol.md` is the **sole and authoritative technical standard** for this project.
+- **Law**: All code must adhere to the Axioms (Meaning First, Contract First, etc.) defined in the Protocol.
+- **Syntax & Structure**: Anchors (`[DEF]`), Tags (`@KEY`), and File Structures must strictly match the Protocol.
+- **Compliance**: Any deviation from `semantic_protocol.md` constitutes a build failure.
 
-### II. Causal Validity (Contracts First)
-As defined in the Protocol, Semantic definitions (Contracts) must ALWAYS precede implementation code. Logic is downstream of definition. We define the structure and constraints (`[DEF]`, `@PRE`, `@POST`) before writing the executable logic.
-
-### III. Immutability of Architecture
-Architectural decisions in the Module Header (`@LAYER`, `@INVARIANT`, `@CONSTRAINT`) are treated as immutable constraints. Changes to these require an explicit refactoring step, not ad-hoc modification during implementation.
-
-### IV. Design by Contract (DbC)
-Contracts are the Source of Truth. Functions and Classes must define their purpose, specifications, and constraints in the metadata block before implementation, strictly following the **Contracts (Section IV)** standard in `semantic_protocol.md`.
-
-### V. Belief State Logging
-Agents must maintain belief state logs for debugging and coherence checks, strictly following the **Logging Standard (Section V)** defined in `semantic_protocol.md`.
-
-### VI. Fractal Complexity Limit
-To maintain semantic coherence, code must adhere to the complexity limits (Module/Function size) defined in the **Fractal Complexity Limit (Section VI)** of `semantic_protocol.md`.
-
-### VII. Everything is a Plugin
+### II. Everything is a Plugin
 All functional extensions, tools, or major features must be implemented as modular Plugins inheriting from `PluginBase`. Logic should not reside in standalone services or scripts unless strictly necessary for core infrastructure. This ensures a unified execution model via the `TaskManager`, consistent logging, and modularity.
 
-### VIII. Unified Frontend Experience
+### III. Unified Frontend Experience
 To ensure a consistent and accessible user experience, all frontend implementations must strictly adhere to the unified design and localization standards.
-- **Component Reusability**: All UI elements MUST utilize the standardized Svelte component library (`src/lib/ui`) and centralized design tokens. Ad-hoc styling and hardcoded values are prohibited.
-- **Internationalization (i18n)**: All user-facing text MUST be extracted to the translation system (`src/lib/i18n`). Hardcoded strings in the UI are prohibited.
+- **Component Reusability**: All UI elements MUST utilize the standardized Svelte component library (`src/lib/ui`) and centralized design tokens.
+- **Internationalization (i18n)**: All user-facing text MUST be extracted to the translation system (`src/lib/i18n`).
 
-### IX. Security & Access Control
+### IV. Security & Access Control
 To support the Role-Based Access Control (RBAC) system, all functional components must define explicit permissions.
 - **Granular Permissions**: Every Plugin MUST define a unique permission string (e.g., `plugin:name:execute`) required for its operation.
-- **Registration**: These permissions MUST be registered in the system database during initialization or plugin loading to ensure they are available for role assignment in the Admin UI.
+- **Registration**: These permissions MUST be registered in the system database (`auth.db`) during initialization.
 
-## File Structure Standards
-Refer to **Section III (File Structure Standard)** in `semantic_protocol.md` for the authoritative definitions of:
-- Python Module Headers (`.py`)
-- Svelte Component Headers (`.svelte`)
+### V. Independent Testability
+Every feature specification MUST define "Independent Tests" that allow the feature to be verified in isolation.
+- **Decoupling**: Features should be designed such that they can be tested without requiring the full application state or external dependencies where possible.
+- **Verification**: A feature is not complete until its Independent Test scenarios pass.
 
-## Generation Workflow
-The development process follows a streamlined single-phase workflow:
-
-### 1. Code Generation Phase (Mode: `code`)
-**Input**: `tasks.md`
-**Responsibility**:
-- Select task from `tasks.md`.
-- Generate Scaffolding (`[DEF]` anchors, Headers, Contracts) AND Implementation in one pass.
-- Ensure strict adherence to Protocol Section IV (Contracts) and Section VII (Generation Workflow).
-- **Output**: Working code with passing tests.
-
-### 2. Validation
-If logic conflicts with Contract -> Stop -> Report Error.
+### VI. Asynchronous Execution
+All long-running or resource-intensive operations (migrations, analysis, backups, external API calls) MUST be executed as asynchronous tasks via the `TaskManager`.
+- **Non-Blocking**: HTTP API endpoints MUST NOT block on these operations; they should spawn a task and return a Task ID.
+- **Observability**: Tasks MUST emit real-time status updates via the WebSocket infrastructure.
 
 ## Governance
 This Constitution establishes the "Semantic Code Generation Protocol" as the supreme law of this repository.
 
-- **Authoritative Source**: `semantic_protocol.md` defines the specific implementation rules for these Principles.
-- **Automated Enforcement**: Tools must validate adherence to the `semantic_protocol.md` syntax.
+- **Authoritative Source**: `semantic_protocol.md` defines the specific implementation rules for Principle I.
 - **Amendments**: Changes to core principles require a Constitution amendment. Changes to technical syntax require a Protocol update.
 - **Compliance**: Failure to adhere to the Protocol constitutes a build failure.
