+# Design Document
+
+## Overview
+
+The NASA Solar Image Downloader is a Python application that automatically downloads high-resolution solar images from NASA's Solar Dynamics Observatory (SDO) and provides a video-like interface for viewing image sequences. The system operates continuously, checking for new images every 5 minutes and maintaining a local repository of the last month's solar data.
+
+The application consists of three main components: an image downloader that interfaces with NASA's web repository, a local storage manager that organizes images by date, and a video interface that allows users to view image sequences with playback controls.
+
+## Architecture
+
+The system follows a modular architecture with clear separation of concerns:
+

+## Correctness Properties
+
+*A property is a characteristic or behavior that should hold true across all valid executions of a system-essentially, a formal statement about what the system should do. Properties serve as the bridge between human-readable specifications and machine-verifiable correctness guarantees.*
+
+### Property Reflection
+
+After reviewing all testable properties from the prework analysis, several redundancies were identified:
+- Properties 1.2 and 2.1 both test date path structure creation - consolidated into Property 2
+- Properties related to error logging (1.3, 4.3, 5.2) share similar validation patterns - kept separate as they test different error scenarios
+- Download completion reporting (1.4) and incremental downloading (4.2) test different aspects and remain separate
+
+### Property 1: Last month date range validation
+*For any* system startup date, the Image_Downloader should generate URLs only for dates within the last 30 days and with "_4096_0211" suffix
+**Validates: Requirements 1.1**
+
+### Property 2: Date path structure consistency  
+*For any* valid date, the Local_Storage should create folder structure following "data/YYYY/MM/DD/" pattern
+**Validates: Requirements 1.2, 2.1**
+
+### Property 3: Error resilience during downloads
+*For any* download failure, the Image_Downloader should log the error and continue processing remaining downloads without stopping
+**Validates: Requirements 1.3**
+
+### Property 4: Download count accuracy
+*For any* completed download session, the reported count should equal the actual number of successfully downloaded files
+**Validates: Requirements 1.4**
+
+### Property 5: URL validation consistency
+*For any* generated NASA SDO URL, the validation should accept well-formed URLs and reject malformed ones consistently
+**Validates: Requirements 1.5**
+
+### Property 6: Filename preservation
+*For any* downloaded image, the local filename should exactly match the original NASA filename format
+**Validates: Requirements 2.2**
+
+### Property 7: Duplicate detection
+*For any* image that already exists locally, attempting to download it again should skip the download and leave the existing file unchanged
+**Validates: Requirements 2.3**
+
+### Property 8: File integrity verification
+*For any* downloaded image, the local file size should match the expected size from the HTTP response headers
+**Validates: Requirements 2.4**
+
+### Property 9: Time sequence ordering
+*For any* collection of images with timestamps, the Video_Interface should display them in chronological order based on their time sequence
+**Validates: Requirements 3.1**
+
+### Property 10: Frame navigation consistency
+*For any* current frame position, stepping forward then backward should return to the original frame
+**Validates: Requirements 3.3**
+
+### Property 11: Metadata display accuracy
+*For any* currently displayed image, the shown timestamp and position should match the actual image metadata
+**Validates: Requirements 3.4**
+
+### Property 12: Missing image graceful handling
+*For any* image sequence with gaps, the Video_Interface should continue functioning without crashes when encountering missing files
+**Validates: Requirements 3.5**
+
+### Property 13: Incremental download behavior
+*For any* monitoring check, only images not already present in Local_Storage should be added to the download queue
+**Validates: Requirements 4.2**
+
+### Property 14: Monitoring cycle logging
+*For any* 5-minute check cycle, appropriate log entries should be created documenting the check time and results
+**Validates: Requirements 4.3**
+
+### Property 15: Empty check handling
+*For any* monitoring cycle that finds no new images, the system should continue to the next cycle without errors
+**Validates: Requirements 4.5**
+
+### Property 16: Exponential backoff retry pattern
+*For any* network timeout, subsequent retry attempts should follow exponential backoff timing (1s, 2s, 4s, 8s, etc.)
+**Validates: Requirements 5.1**
+
+### Property 17: HTTP error logging and continuation
+*For any* HTTP error response, the specific error code should be logged and processing should continue with remaining requests
+**Validates: Requirements 5.2**
+
+### Property 18: Failed request queuing
+*For any* server unavailability scenario, failed download requests should be added to a retry queue for later processing
+**Validates: Requirements 5.3**
+
+### Property 19: Rate limiting compliance
+*For any* sequence of download requests, the time interval between requests should respect the configured rate limit
+**Validates: Requirements 5.4**
+
+### Property 20: Connection recovery resumption
+*For any* queued downloads when connection is restored, all pending downloads should automatically resume processing
+**Validates: Requirements 5.5**
+
+## Error Handling
+
+The system implements comprehensive error handling across all components:
+
+### Network Error Handling
+- **Connection timeouts**: Exponential backoff retry with maximum 5 attempts
+- **HTTP errors**: Log specific error codes (404, 500, etc.) and continue processing
+- **Rate limiting**: Implement delays between requests to respect NASA server limits
+- **Server unavailability**: Queue failed requests for automatic retry when service resumes
+
+### File System Error Handling  
+- **Disk space**: Check available space before downloads and notify user if insufficient
+- **Permission errors**: Handle read/write permission issues with clear error messages
+- **Corrupted files**: Validate file integrity and re-download if corruption detected
+- **Missing directories**: Automatically create required folder structure
+
+### UI Error Handling
+- **Missing images**: Display placeholder or skip gracefully in video sequence
+- **Invalid date ranges**: Validate user input and provide helpful error messages  
+- **Playback errors**: Handle corrupted or unreadable image files without crashing
+- **Memory issues**: Implement image caching and cleanup for large sequences
+
+## Testing Strategy
+
+The testing approach combines unit testing for specific functionality with property-based testing for universal behaviors:
+
+### Unit Testing Framework
+- **Framework**: pytest for Python unit testing
+- **Coverage**: Focus on specific examples, edge cases, and integration points
+- **Mock objects**: Use unittest.mock for external dependencies (NASA servers, file system)
+- **Test data**: Create sample image files and mock HTTP responses for testing
+
+### Property-Based Testing Framework  
+- **Framework**: Hypothesis for Python property-based testing
+- **Configuration**: Minimum 100 iterations per property test to ensure thorough coverage
+- **Generators**: Custom generators for dates, URLs, file paths, and image metadata
+- **Shrinking**: Leverage Hypothesis shrinking to find minimal failing examples
+
+### Test Organization
+- Unit tests verify specific examples and integration behavior
+- Property tests verify universal correctness properties across all inputs  
+- Each property-based test tagged with format: **Feature: nasa-solar-image-downloader, Property {number}: {property_text}**
+- Tests organized by component (downloader, storage, ui, scheduler)
+- Continuous integration runs both unit and property tests on every commit
+
+### Test Data Management
+- Mock NASA server responses for reliable testing
+- Generate test images with known metadata for validation
+- Create temporary directories for file system testing
+- Use time mocking for scheduler and timing-dependent tests

+- **Image_Downloader**: The component responsible for fetching images from NASA servers
+- **Local_Storage**: The local "data" folder where downloaded images are stored
+- **Video_Interface**: The user interface component that displays image sequences
+- **Date_Path**: The hierarchical folder structure based on date (YYYY/MM/DD format)
+- **Time_Sequence**: The sequential numbering system used by NASA for images (HHMMSS format)
+- **Resolution_Code**: The image resolution identifier (4096 for high resolution)
+- **Instrument_Code**: The specific NASA instrument identifier (0211 for AIA 211 Angstrom)
+- **Monitoring_Cycle**: The 5-minute interval system for checking new images

+BLP1 files, used mostly in Warcraft III, are not fully supported.
+All types of BLP2 files used in World of Warcraft are supported.
+
+The BLP file structure consists of a header, up to 16 mipmaps of the
+texture
+
+Texture sizes must be powers of two, though the two dimensions do
+not have to be equal; 512x256 is valid, but 512x200 is not.
+The first mipmap (mipmap #0) is the full size image; each subsequent
+mipmap halves both dimensions. The final mipmap should be 1x1.
+
+BLP files come in many different flavours:
+* JPEG-compressed (type == 0) - only supported for BLP1.
+* RAW images (type == 1, encoding == 1). Each mipmap is stored as an
+  array of 8-bit values, one per pixel, left to right, top to bottom.
+  Each value is an index to the palette.
+* DXT-compressed (type == 1, encoding == 2):
+- DXT1 compression is used if alpha_encoding == 0.
+  - An additional alpha bit is used if alpha_depth == 1.
+  - DXT3 compression is used if alpha_encoding == 1.
+  - DXT5 compression is used if alpha_encoding == 7.

+Independence War 2: Edge Of Chaos - Texture File Format - 16 October 2001
+
+The textures used for 3D objects in Independence War 2: Edge Of Chaos are in a
+packed custom format called FTEX. This file format uses file extensions FTC
+and FTU.
+* FTC files are compressed textures (using standard texture compression).
+* FTU files are not compressed.
+Texture File Format
+The FTC and FTU texture files both use the same format. This
+has the following structure:
+{header}
+{format_directory}
+{data}
+Where:
+{header} = {
+    u32:magic,
+    u32:version,
+    u32:width,
+    u32:height,
+    u32:mipmap_count,
+    u32:format_count
+}
+
+* The "magic" number is "FTEX".
+* "width" and "height" are the dimensions of the texture.
+* "mipmap_count" is the number of mipmaps in the texture.
+* "format_count" is the number of texture formats (different versions of the
+same texture) in this file.
+
+{format_directory} = format_count * { u32:format, u32:where }
+
+The format value is 0 for DXT1 compressed textures and 1 for 24-bit RGB
+uncompressed textures.
+The texture data for a format starts at the position "where" in the file.
+
+Each set of texture data in the file has the following structure:
+{data} = format_count * { u32:mipmap_size, mipmap_size * { u8 } }
+* "mipmap_size" is the number of bytes in that mip level. For compressed
+textures this is the size of the texture data compressed with DXT1. For 24 bit
+uncompressed textures, this is 3 * width * height. Following this are the image
+bytes for that mipmap level.
+
+Note: All data is stored in little-Endian (Intel) byte order.

+
+    The pyCMS.py module provides a "clean" interface between Python/PIL and
+    pyCMSdll, taking care of some of the more complex handling of the direct
+    pyCMSdll functions, as well as error-checking and making sure that all
+    relevant data is kept together.
+
+    While it is possible to call pyCMSdll functions directly, it's not highly
+    recommended.
+
+    Version History:
+
+        1.0.0 pil       Oct 2013 Port to LCMS 2.
+
+        0.1.0 pil mod   March 10, 2009
+
+                        Renamed display profile to proof profile. The proof
+                        profile is the profile of the device that is being
+                        simulated, not the profile of the device which is
+                        actually used to display/print the final simulation
+                        (that'd be the output profile) - also see LCMSAPI.txt
+                        input colorspace -> using 'renderingIntent' -> proof
+                        colorspace -> using 'proofRenderingIntent' -> output
+                        colorspace
+
+                        Added LCMS FLAGS support.
+                        Added FLAGS["SOFTPROOFING"] as default flag for
+                        buildProofTransform (otherwise the proof profile/intent
+                        would be ignored).
+
+        0.1.0 pil       March 2009 - added to PIL, as PIL.ImageCms
+
+        0.0.2 alpha     Jan 6, 2002
+
+                        Added try/except statements around type() checks of
+                        potential CObjects... Python won't let you use type()
+                        on them, and raises a TypeError (stupid, if you ask
+                        me!)
+
+                        Added buildProofTransformFromOpenProfiles() function.
+                        Additional fixes in DLL, see DLL code for details.
+
+        0.0.1 alpha     first public release, Dec. 26, 2002

+
+    How are the vertices computed?
+    1. Compute the following variables
+        - theta: Angle between the apothem & the nearest polygon vertex
+        - side_length: Length of each polygon edge
+        - centroid: Center of bounding circle (1st, 2nd elements of bounding_circle)

+
+    2. For each angle in angles, get the polygon vertex at that angle
+        The vertex is computed using the equation below.
+            X= xcos(φ) + ysin(φ)
+            Y= −xsin(φ) + ycos(φ)

+            y = polygon_radius
+
+        The formula above assumes rotation around the origin.
+        In our case, we are rotating around the centroid.
+        To account for this, we use the formula below
+            X = xcos(φ) + ysin(φ) + centroid_x
+            Y = −xsin(φ) + ycos(φ) + centroid_y

+# PIL raster font management
+#
+# History:
+# 1996-08-07 fl   created (experimental)
+# 1997-08-25 fl   minor adjustments to handle fonts from pilfont 0.3
+# 1999-02-06 fl   rewrote most font management stuff in C
+# 1999-03-17 fl   take pth files into account in load_path (from Richard Jones)
+# 2001-02-17 fl   added freetype support
+# 2001-05-09 fl   added TransposedFont wrapper class
+# 2002-03-04 fl   make sure we have a "L" or "1" font
+# 2002-12-04 fl   skip non-directory entries in the system path
+# 2003-04-29 fl   add embedded default font
+# 2003-09-27 fl   added support for truetype charmap encodings
+#
