 # Semantic Code Generation Constitution
 
 ## Core Principles
 
-### I. Causal Validity (Contracts First)
+### I. Semantic Protocol Compliance
-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. This ensures that the "what" and "why" govern the "how".
+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.
 
-### II. Immutability of Architecture
+### II. Causal Validity (Contracts First)
-Once defined, architectural decisions in the Module Header (`@LAYER`, `@INVARIANT`, `@CONSTRAINT`) are treated as immutable constraints for that module. Changes to these require an explicit refactoring step, not ad-hoc modification during implementation.
+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. Semantic Format Compliance
+### III. Immutability of Architecture
-All output must strictly follow the `[DEF]` / `[/DEF]` anchor syntax with specific Metadata Tags (`@KEY`) and Graph Relations (`@RELATION`). **Crucially, the closing anchor must strictly match the full content of the opening anchor (e.g., `[DEF:identifier:Type]` must close with `[/DEF:identifier:Type]`).**
+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.
-
-**Standardized Graph Relations**
-To ensure the integrity of the Semantic Graph, `@RELATION` must use a strict taxonomy:
-- `DEPENDS_ON` (Structural dependency)
-- `CALLS` (Flow control)
-- `CREATES` (Instantiation)
-- `INHERITS_FROM` / `IMPLEMENTS` (OOP hierarchy)
-- `READS_STATE` / `WRITES_STATE` (Data flow)
-- `DISPATCHES` / `HANDLES` (Event flow)
-
-Ad-hoc relationships are forbidden. This structure is non-negotiable as it ensures the codebase remains machine-readable, fractal-structured, and optimized for Sparse Attention navigation by AI agents.
 
 ### IV. Design by Contract (DbC)
-Contracts are the Source of Truth. Functions and Classes must define their purpose, specifications, and constraints (`@PRE`, `@POST`, `@THROW`) in the metadata block before implementation. Implementation must strictly satisfy these contracts.
+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
-Logs must define the agent's internal state for debugging and coherence checks. We use a strict format: `[{ANCHOR_ID}][{STATE}] {MESSAGE}`. For Python, a **Context Manager** pattern MUST be used to automatically handle `Entry`, `Exit`, and `Coherence` states, ensuring structural integrity and error capturing.
+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 and avoid "Attention Sink" issues:
+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`.
-- **Module Size**: If a Module body exceeds ~300 lines (or logical complexity), it MUST be refactored into sub-modules or a package structure.
-- **Function Size**: Functions should fit within a standard attention "chunk" (approx. 30-50 lines). If larger, logic MUST be decomposed into helper functions with their own contracts.
 
-This ensures every vector embedding remains sharp and focused.
+### VII. 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
+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.
 
 ## File Structure Standards
-
+Refer to **Section III (File Structure Standard)** in `semantic_protocol.md` for the authoritative definitions of:
-### Python Modules
+- Python Module Headers (`.py`)
-Every `.py` file must start with a Module definition header (`[DEF:module_name:Module]`) containing:
+- Svelte Component Headers (`.svelte`)
-- `@SEMANTICS`: Keywords for vector search.
-- `@PURPOSE`: Primary responsibility of the module.
-- `@LAYER`: Architecture layer (Domain/Infra/UI).
-- `@RELATION`: Dependencies.
-- `@INVARIANT` & `@CONSTRAINT`: Immutable rules.
-- `@PUBLIC_API`: Exported symbols.
-
-### Svelte Components
-Every `.svelte` file must start with a Component definition header (`[DEF:ComponentName:Component]`) wrapped in an HTML comment `<!-- ... -->` containing:
-- `@SEMANTICS`: Keywords for vector search.
-- `@PURPOSE`: Primary responsibility of the component.
-- `@LAYER`: Architecture layer (UI/State/Layout).
-- `@RELATION`: Child components, Stores used, API calls.
-- `@PROPS`: Input properties.
-- `@EVENTS`: Emitted events.
-- `@INVARIANT`: Immutable UI/State rules.
 
 ## Generation Workflow
-The development process follows a strict sequence enforced by Agent Roles:
+The development process follows a streamlined single-phase workflow:
 
-### 1. Architecture Phase (Mode: `tech-lead`)
+### 1. Code Generation Phase (Mode: `code`)
-**Input**: `tasks-arch.md`
+**Input**: `tasks.md`
 **Responsibility**:
-- Analyze request and graph position.
+- Select task from `tasks.md`.
-- Generate `[DEF]` anchors, Headers, and Contracts (`@PRE`, `@POST`).
+- Generate Scaffolding (`[DEF]` anchors, Headers, Contracts) AND Implementation in one pass.
-- **Output**: Scaffolding files with no implementation logic.
+- Ensure strict adherence to Protocol Section IV (Contracts) and Section VII (Generation Workflow).
-
-### 2. Implementation Phase (Mode: `code`)
-**Input**: `tasks-dev.md` + Scaffolding files
-**Responsibility**:
-- Read contracts defined by Architect.
-- Write implementation code that strictly satisfies contracts.
 - **Output**: Working code with passing tests.
 
-### 3. Validation
+### 2. Validation
 If logic conflicts with Contract -> Stop -> Report Error.
 
 ## Governance
 This Constitution establishes the "Semantic Code Generation Protocol" as the supreme law of this repository.
 
-- **Automated Enforcement**: All code generation tools and agents must parse and validate adherence to the `[DEF]` syntax and Contract requirements.
+- **Authoritative Source**: `semantic_protocol.md` defines the specific implementation rules for these Principles.
-- **Amendments**: Changes to the syntax or core principles require a formal amendment to this Constitution and a corresponding update to the constitution
+- **Automated Enforcement**: Tools must validate adherence to the `semantic_protocol.md` syntax.
-- **Review**: Code reviews must verify that implementation matches the preceding contracts and that no "naked code" exists outside of semantic anchors.
+- **Amendments**: Changes to core principles require a Constitution amendment. Changes to technical syntax require a Protocol update.
-- **Compliance**: Failure to adhere to the `[DEF]` / `[/DEF]` structure (including matching closing tags) constitutes a build failure.
+- **Compliance**: Failure to adhere to the Protocol constitutes a build failure.

+
+**Checkpoint**: Foundation ready - user story implementation can now begin in parallel
+
+---
+
+## Phase 3: User Story 1 - [Title] (Priority: P1) 🎯 MVP
+
+**Goal**: [Brief description of what this story delivers]
+
+**Independent Test**: [How to verify this story works on its own]
+
+### Tests for User Story 1 (OPTIONAL - only if tests requested) ⚠️
+
+> **NOTE: Write these tests FIRST, ensure they FAIL before implementation**
+
+- [ ] T010 [P] [US1] Contract test for [endpoint] in tests/contract/test_[name].py
+- [ ] T011 [P] [US1] Integration test for [user journey] in tests/integration/test_[name].py
+
+### Implementation for User Story 1
+
+- [ ] T012 [P] [US1] Create [Entity1] model in src/models/[entity1].py
+- [ ] T013 [P] [US1] Create [Entity2] model in src/models/[entity2].py
+- [ ] T014 [US1] Implement [Service] in src/services/[service].py (depends on T012, T013)
+- [ ] T015 [US1] Implement [endpoint/feature] in src/[location]/[file].py
+- [ ] T016 [US1] Add validation and error handling
+- [ ] T017 [US1] Add logging for user story 1 operations
+
+**Checkpoint**: At this point, User Story 1 should be fully functional and testable independently
+
+---
+
+## Phase 4: User Story 2 - [Title] (Priority: P2)
+
+**Goal**: [Brief description of what this story delivers]
+
+**Independent Test**: [How to verify this story works on its own]
+
+### Tests for User Story 2 (OPTIONAL - only if tests requested) ⚠️
+
+- [ ] T018 [P] [US2] Contract test for [endpoint] in tests/contract/test_[name].py
+- [ ] T019 [P] [US2] Integration test for [user journey] in tests/integration/test_[name].py
+
+### Implementation for User Story 2
+
+- [ ] T020 [P] [US2] Create [Entity] model in src/models/[entity].py
+- [ ] T021 [US2] Implement [Service] in src/services/[service].py
+- [ ] T022 [US2] Implement [endpoint/feature] in src/[location]/[file].py
+- [ ] T023 [US2] Integrate with User Story 1 components (if needed)
+
+**Checkpoint**: At this point, User Stories 1 AND 2 should both work independently
+
+---
+
+## Phase 5: User Story 3 - [Title] (Priority: P3)
+
+**Goal**: [Brief description of what this story delivers]
+
+**Independent Test**: [How to verify this story works on its own]
+
+### Tests for User Story 3 (OPTIONAL - only if tests requested) ⚠️
+
+- [ ] T024 [P] [US3] Contract test for [endpoint] in tests/contract/test_[name].py
+- [ ] T025 [P] [US3] Integration test for [user journey] in tests/integration/test_[name].py
+
+### Implementation for User Story 3
+
+- [ ] T026 [P] [US3] Create [Entity] model in src/models/[entity].py
+- [ ] T027 [US3] Implement [Service] in src/services/[service].py
+- [ ] T028 [US3] Implement [endpoint/feature] in src/[location]/[file].py
+
+**Checkpoint**: All user stories should now be independently functional
+
+---
+
+[Add more user story phases as needed, following the same pattern]
+
+---
+
+## Phase N: Polish & Cross-Cutting Concerns
+
+**Purpose**: Improvements that affect multiple user stories
+
+- [ ] TXXX [P] Documentation updates in docs/
+- [ ] TXXX Code cleanup and refactoring
+- [ ] TXXX Performance optimization across all stories
+- [ ] TXXX [P] Additional unit tests (if requested) in tests/unit/
+- [ ] TXXX Security hardening
+- [ ] TXXX Run quickstart.md validation
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: No dependencies - can start immediately
+- **Foundational (Phase 2)**: Depends on Setup completion - BLOCKS all user stories
+- **User Stories (Phase 3+)**: All depend on Foundational phase completion
+  - User stories can then proceed in parallel (if staffed)
+  - Or sequentially in priority order (P1 → P2 → P3)
+- **Polish (Final Phase)**: Depends on all desired user stories being complete
+
+### User Story Dependencies
+
+- **User Story 1 (P1)**: Can start after Foundational (Phase 2) - No dependencies on other stories
+- **User Story 2 (P2)**: Can start after Foundational (Phase 2) - May integrate with US1 but should be independently testable
+- **User Story 3 (P3)**: Can start after Foundational (Phase 2) - May integrate with US1/US2 but should be independently testable
+
+### Within Each User Story
+
+- Tests (if included) MUST be written and FAIL before implementation
+- Models before services
+- Services before endpoints
+- Core implementation before integration
+- Story complete before moving to next priority
+
+### Parallel Opportunities
+
+- All Setup tasks marked [P] can run in parallel
+- All Foundational tasks marked [P] can run in parallel (within Phase 2)
+- Once Foundational phase completes, all user stories can start in parallel (if team capacity allows)
+- All tests for a user story marked [P] can run in parallel
+- Models within a story marked [P] can run in parallel
+- Different user stories can be worked on in parallel by different team members
+
+---
+
+## Parallel Example: User Story 1
+
+```bash
+# Launch all tests for User Story 1 together (if tests requested):
+Task: "Contract test for [endpoint] in tests/contract/test_[name].py"
+Task: "Integration test for [user journey] in tests/integration/test_[name].py"
+
+# Launch all models for User Story 1 together:
+Task: "Create [Entity1] model in src/models/[entity1].py"
+Task: "Create [Entity2] model in src/models/[entity2].py"
+```
+
+---
+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 1: Setup
+2. Complete Phase 2: Foundational (CRITICAL - blocks all stories)
+3. Complete Phase 3: User Story 1
+4. **STOP and VALIDATE**: Test User Story 1 independently
+5. Deploy/demo if ready
+
+### Incremental Delivery
+
+1. Complete Setup + Foundational → Foundation ready
+2. Add User Story 1 → Test independently → Deploy/Demo (MVP!)
+3. Add User Story 2 → Test independently → Deploy/Demo
+4. Add User Story 3 → Test independently → Deploy/Demo
+5. Each story adds value without breaking previous stories
+
+### Parallel Team Strategy
+
+With multiple developers:
+
+1. Team completes Setup + Foundational together
+2. Once Foundational is done:
+   - Developer A: User Story 1
+   - Developer B: User Story 2
+   - Developer C: User Story 3
+3. Stories complete and integrate independently
+
+---
+
+## Notes
+
+- [P] tasks = different files, no dependencies
+- [Story] label maps task to specific user story for traceability
+- Each user story should be independently completable and testable
+- Verify tests fail before implementing
+- Commit after each task or logical group
+- Stop at any checkpoint to validate story independently
+- Avoid: vague tasks, same file conflicts, cross-story dependencies that break independence

- * 
- * ```

- * Similar to [`$env/dynamic/private`](https://svelte.dev/docs/kit/$env-dynamic-private), but only includes variables that begin with [`config.kit.env.publicPrefix`](https://svelte.dev/docs/kit/configuration#env) (which defaults to `PUBLIC_`), and can therefore safely be exposed to client-side code.
- * 
- * Note that public dynamic environment variables must all be sent from the server to the client, causing larger network requests — when possible, use `$env/static/public` instead.
- * 
- * ```ts
- * import { env } from '$env/dynamic/public';
- * console.log(env.PUBLIC_DEPLOYMENT_SPECIFIC_VARIABLE);
- * ```
