**Persona: "The Quick Jotter - Sarah"**
*   **Demographics:** 28 years old, Marketing Coordinator, tech-savvy but prefers minimal overhead for personal tools.
*   **Needs:** Needs a place to quickly jot down ideas, to-do items, meeting notes, or fleeting thoughts without signing up for an account or relying on cloud services. Values simplicity and speed.
*   **Pain Points:** Existing note apps often require logins, have too many features, or are slow to load. Wants something that just works in her browser.
*   **User Journey:**
    1.  Opens the Notes App in her browser.
    2.  Sees a list of her existing notes, or an empty state if none exist.
    3.  Quickly creates a new note with a title and content.
    4.  Saves the note, sees it appear in the list.
    5.  Later, finds an existing note, edits its content, and updates it.
    6.  Deletes old notes she no longer needs.
    7.  Closes the browser, re-opens later, and expects her notes to still be there.

## 4. Problem Statement
Users often require a simple, readily available tool for personal note-taking that prioritizes speed and local data storage without the complexity, overhead, or privacy concerns associated with cloud-based solutions or external backend services. Existing solutions can be overly feature-rich, require accounts, or introduce dependencies that are unnecessary for basic local note management.

## 5. Solution Overview
The Notes Application will be a web-based, client-side feature module integrated into the Angular Clarity Boilerplate. It will provide a user-friendly interface for managing text notes. Core features will include creating new notes with a title, content, and auto-generated creation date; viewing a list of all saved notes; editing the title and content of existing notes; and permanently deleting notes.

## 9. User Interface Requirements
*   **Clarity Design System Adherence:** All UI elements (buttons, input fields, text areas, lists, modals for confirmation) must utilize components and styling from the VMware Clarity Design System for consistency with the base boilerplate, as referenced in `tech_stack_document.md`.
*   **Note Form:** A clean form with distinct input fields for 'Title' (single line) and 'Content' (multi-line text area). A clear 'Save' button is required.
*   **Note List Display:** Notes should be presented in a clear, scrollable list. Each list item should prominently display the note's title and optionally a content snippet and creation date. Each item must include distinct 'Edit' and 'Delete' controls.
*   **Responsive Design:** The UI should be functional and aesthetically pleasing across common desktop browser sizes. (Inherited from Angular Clarity Boilerplate).
*   **Empty State:** A clear message should be displayed when no notes are present in local storage, guiding the user to create their first note.

## 10. Technical Requirements
*   **Angular Framework:** The application will be built using Angular components, services, and modules, adhering to best practices for maintainability and scalability, as specified in `tech_stack_document.md`.
*   **TypeScript:** All application logic will be written in TypeScript, ensuring strong typing for the `Note` data model and improved code quality.
*   **LocalStorageService:** A dedicated Angular service (`LocalStorageService`) will encapsulate all interactions with the browser's `localStorage` API, acting as the data access layer as per `architecture_document.md`.
*   **NotesModule:** The Notes app will be implemented as a lazy-loaded Angular feature module (`NotesModule`) to ensure modularity and efficient resource loading, as per `architecture_document.md`.
*   **Component Structure:** Adhere to the component hierarchy outlined in `architecture_document.md`: `NotesPageComponent` (container), `NoteFormComponent`, `NoteListComponent`, and `NoteItemComponent` (presentational).
*   **Reactive Programming:** Utilize RxJS for managing asynchronous data flows from `LocalStorageService` to UI components, ensuring real-time updates.
*   **Unique ID Generation:** Implement a robust mechanism (e.g., UUID library or timestamp-based generation) for creating unique `id`s for each note.
*   **Date Stamping:** Automatically capture the creation date using `Date.toISOString()` for consistent formatting.

## 11. Success Metrics & KPIs
*   **CRUD Operation Success Rate:** 100% of attempted create, read, update, and delete operations complete without errors under normal conditions.
*   **Local Storage Reliability:** 100% of notes saved are successfully retrieved upon subsequent application loads.
*   **Feature Completeness:** All user stories for Epic 1 (Note Management) are implemented and meet their acceptance criteria.
*   **UI/UX Adherence:** The application passes a review for consistency with Clarity Design System guidelines.
*   **Code Quality:** Adherence to Angular best practices, maintainability, and test coverage for core logic.

## 12. Risk Assessment
*   **Local Storage Capacity Limits:** `localStorage` typically has a 5-10MB limit. Risk: Data loss or inability to save new notes if exceeded. Mitigation: Inform users in documentation; design for graceful failure (e.g., error message) if storage is full. Not critical for MVP due to typical note size.
*   **Browser Compatibility:** Inconsistent `localStorage` behavior or UI rendering across browsers. Mitigation: Test on major modern browsers (Chrome, Firefox, Edge, Safari).
*   **Accidental Data Loss:** Users might clear browser data, losing all notes. Risk: User dissatisfaction. Mitigation: User awareness (documentation); consider a simple export/import feature for future enhancements, but not for MVP.
*   **Security (XSS/Data Tampering):** Data in `localStorage` is accessible to scripts from the same origin. Risk: Malicious scripts could read/modify notes. Mitigation: Rely on Angular's built-in sanitization; primarily a client-side concern, less critical for a personal local app than multi-user systems.
*   **Scope Creep:** Temptation to add features beyond core CRUD (e.g., search, tags, markdown). Mitigation: Strict adherence to MVP definition; backlog additional features for future iterations.

## 13. Timeline & Milestones
*   **M1: PRD Completion:** End of current PM agent execution.
*   **M2: `LocalStorageService` & `Note` Model Implementation:** Target completion within 2 days post-PM.
*   **M3: Notes UI & Core CRUD Functionality (Create/Read/Delete):** Target completion within 5 days post-PM.
