# Feature Specification: Anonymous Feedback Platform (Reklamator)

**Feature Branch**: `001-build-an-application`
**Created**: 2025-10-14
**Status**: Draft
**Input**: User description: "Build an application enables users to anonymously hand in ideas, feature requests, bugs and complaints for a product or a service. The feedback will be then analysed using a modern ai model and translated to a language of the responsible person of that product or service. The analysis as well as belonging the documents or images will be stored toghether as files in a folder. The results are accessible for responsible persons of that product or service in a dashboard. The user is free to submit the feedback in any form or language in a text area. In addition to that he can upload up to three documents or images. The Idea is to lower barriers for feedback and to make it easier to get feedback from users."

## User Scenarios & Testing *(mandatory)*

### User Story 1 - Anonymous Feedback Submission (Priority: P1)

As an end user of a product or service, I want to submit feedback (ideas, bugs, complaints, feature requests) completely anonymously in any language without requiring authentication, so that I can share my thoughts without barriers or fear of identification.

**Why this priority**: This is the core value proposition - enabling barrier-free feedback submission. Without this, the entire application has no purpose. It must be the first deliverable.

**Independent Test**: Can be fully tested by visiting a feedback submission form for a product, entering feedback text in any language, optionally uploading up to 3 files (documents/images), and successfully submitting without any login or personal information required. The submission should complete and provide confirmation to the user.

**Acceptance Scenarios**:

1. **Given** I am on a product's feedback submission page, **When** I enter feedback text in English and click submit, **Then** I see a success confirmation message and my feedback is recorded
2. **Given** I am on a feedback submission page, **When** I enter feedback text in German, Spanish, Japanese, or any other language, **Then** the system accepts my feedback without language restrictions
3. **Given** I am entering feedback, **When** I attach 1 document (PDF, DOCX, TXT) or image (JPG, PNG), **Then** the file is uploaded and associated with my feedback
4. **Given** I am entering feedback, **When** I attach 3 documents/images (at maximum limit), **Then** all files are successfully uploaded
5. **Given** I have attached 3 files, **When** I attempt to attach a 4th file, **Then** the system prevents the upload and informs me of the 3-file limit
6. **Given** I submit feedback, **When** the submission completes, **Then** no personal identifying information about me is stored or required
7. **Given** I submit feedback with only text and no files, **When** the submission completes, **Then** the feedback is accepted successfully
8. **Given** I submit feedback with only files and no text, **When** the submission completes, **Then** the feedback is accepted successfully

### User Story 2 - AI-Powered Feedback Analysis and Translation (Priority: P2)

As a product owner or service manager, I want submitted feedback to be automatically analyzed by AI to categorize it (idea, bug, complaint, feature request), summarize key points, and translate it to my preferred language, so that I can quickly understand feedback regardless of the original language it was submitted in.

**Why this priority**: This is the intelligence layer that adds value beyond basic feedback collection. It enables product owners to efficiently process multilingual feedback. It depends on P1 (feedback must be submitted first), but can be developed and tested independently once P1 exists.

**Independent Test**: Can be tested by submitting feedback in various languages (e.g., German, French, Japanese) through the submission form and verifying that the analysis produces: (1) correct categorization (idea/bug/complaint/feature request), (2) a concise summary in the product owner's preferred language, (3) accurate translation of the original text, and (4) proper storage of analysis results with the original feedback.

**Acceptance Scenarios**:

1. **Given** feedback has been submitted in Spanish, **When** AI analysis runs, **Then** the feedback is correctly categorized as one of: idea, bug, complaint, or feature request
2. **Given** feedback has been submitted in Japanese, **When** AI analysis runs with target language set to English, **Then** the feedback text is accurately translated to English
3. **Given** feedback contains a detailed description, **When** AI analysis runs, **Then** a concise summary (2-3 sentences) is generated capturing the main points in the target language
4. **Given** feedback includes uploaded images, **When** AI analysis runs, **Then** images are stored as visual attachments (OCR is not performed)
5. **Given** AI analysis completes, **When** storing results, **Then** the original feedback, translation, summary, category, and all uploaded files are stored together in a structured format
6. **Given** AI analysis encounters an error or unsupported language, **When** storing results, **Then** the system flags the feedback as requiring manual review and stores the original content intact
7. **Given** feedback is submitted in the same language as the product's target language, **When** AI analysis runs, **Then** categorization and summary still occur but translation may be skipped or indicate "original language"

### User Story 3 - Product Owner Dashboard Access (Priority: P3)

As a product owner or responsible person for a product/service, I want to access a dashboard where I can view all feedback submitted for my product, including the AI analysis results, translations, and attached files, so that I can review and act on user feedback efficiently.

**Why this priority**: This completes the feedback loop by making analyzed feedback accessible. It's lower priority because feedback can still be collected and analyzed without the dashboard (results could be accessed via file system initially). However, it's essential for production use.

**Independent Test**: Can be tested by authenticating as a product owner, navigating to the dashboard, and verifying that all feedback items for their product(s) are displayed with: original text, translation, AI summary, category, submission date, and links to any attached files. The dashboard should be filterable and searchable.

**Acceptance Scenarios**:

1. **Given** I am a product owner with credentials, **When** I log into the dashboard, **Then** I see only feedback related to my assigned product(s)
2. **Given** I am viewing the dashboard, **When** I click on a feedback item, **Then** I see the complete details including original text, detected original language, translation, AI summary, category, submission timestamp, and any attached files
3. **Given** there are multiple feedback items, **When** I use the filter controls, **Then** I can filter by category (idea/bug/complaint/feature request)
4. **Given** there are multiple feedback items, **When** I use the filter controls, **Then** I can filter by date range
5. **Given** there are multiple feedback items, **When** I use the filter controls, **Then** I can filter by original language of submission
6. **Given** I am viewing a feedback item with attached files, **When** I click on a file link, **Then** the file (document or image) opens or downloads for viewing
7. **Given** there are many feedback items, **When** I use the search function, **Then** I can search by keywords in original text, translation, or summary
8. **Given** I am viewing the dashboard, **When** new feedback is submitted and analyzed, **Then** it appears in my dashboard (within reasonable timeframe)
9. **Given** I am viewing a feedback item, **When** I mark it with a status (reviewed, in progress, resolved, rejected), **Then** the status is saved and visible on subsequent views

### User Story 4 - Product/Service Registration and Management ~~(Priority: P4)~~ **[DEFERRED FOR POC]**

~~As a platform administrator, I want to register new products or services in the system and assign responsible persons (product owners) to them, so that feedback can be properly routed and access controlled.~~

**Status**: **DEFERRED** - Out of scope for POC. Products and users will be managed manually via YAML configuration files.

**Rationale**: For a proof-of-concept, manual management of products and users through configuration files is sufficient. Building an admin UI for product/user management does not add value at this stage and can be implemented later if the POC proves successful and requires scaling.

**Manual Management Approach**:
- Products: Edit `data/products/{product-id}/config.yaml` directly
- Users: Edit `data/users.yaml` with bcrypt-hashed passwords
- Product assignment: Update `product_ids` field in user records

**Original Requirements** (preserved for future reference):

~~As a platform administrator, I want to register new products or services in the system and assign responsible persons (product owners) to them, so that feedback can be properly routed and access controlled.~~

~~**Why this priority**: This is administrative infrastructure needed for multi-product support. It's lower priority because the MVP could work with a single hardcoded product. However, it's necessary for a scalable production system.~~

~~**Independent Test**: Can be tested by logging in as an administrator, creating a new product/service entry with details (name, description, preferred language for translations), assigning one or more product owners to it, and verifying that the product appears in the system with a unique feedback submission URL and that assigned owners can access its feedback in their dashboards.~~

~~**Acceptance Scenarios**:~~

~~1. **Given** I am an administrator, **When** I create a new product entry with name, description, and preferred language for feedback translations, **Then** the product is registered and assigned a unique identifier~~
~~2. **Given** a product exists, **When** I assign a user as a product owner, **Then** that user gains access to view feedback for this product in their dashboard~~
~~3. **Given** a product is registered, **When** I request the feedback submission URL, **Then** I receive a unique URL that end users can use to submit feedback for this specific product~~
~~4. **Given** multiple products exist, **When** feedback is submitted via a product-specific URL, **Then** the feedback is correctly associated with that product and only visible to its assigned owners~~
~~5. **Given** a product exists, **When** I update the preferred translation language setting, **Then** future feedback translations for this product use the new language preference~~
~~6. **Given** a product is registered, **When** I view its settings, **Then** I can see statistics like total feedback count, submission URL, and assigned owners~~
~~7. **Given** a product has historical feedback, **When** I archive the product, **Then** the feedback is preserved but the product is marked inactive and new submissions are disabled~~

### Edge Cases

- What happens when a user uploads a file exceeding the maximum file size limit (assumed 10MB per file)?
- What happens when a user uploads an unsupported file type (e.g., executable, compressed archive)?
- How does the system handle extremely long feedback text (e.g., 10,000+ characters)?
- What happens if AI analysis fails (API timeout, service unavailable, unrecognizable content)?
- How does the system handle feedback submitted in languages not supported by the translation model?
- What happens when a user submits feedback with no text content (only files)?
- What happens when a user submits completely empty feedback (no text, no files)?
- How does the system handle identical or near-identical duplicate submissions?
- What happens if a product owner is assigned to multiple products - how is the dashboard view organized?
- How does the system handle image files that are too large or in exotic formats?
- What happens when a user's browser doesn't support JavaScript - does the submission still work?
- How does the system handle concurrent submissions from the same anonymous user?
- What happens when a product owner tries to download a file that has been corrupted or deleted from storage?
