 ## Phase 1: Basic File Serving & Retrieval (BUD-01)
 
 ### 1.1 Infrastructure Setup
-- [ ] Create basic directory structure
-  - [ ] Create `blobs/` directory for file storage
-  - [ ] Create `db/` directory for SQLite database
-  - [ ] Create `logs/` directory for application logs
-  - [ ] Set up proper permissions (nginx readable, app writable)
+- [x] Create basic directory structure
+  - [x] Create `blobs/` directory for file storage
+  - [x] Create `db/` directory for SQLite database
+  - [x] Create `logs/` directory for application logs
+  - [x] Set up proper permissions (nginx readable, app writable)
 
 ### 1.2 Database Schema
-- [ ] Design SQLite schema for blob metadata
-  - [ ] `blobs` table: sha256, size, type, uploaded_at, uploader_pubkey
-  - [ ] `server_config` table: key-value pairs for server settings
-  - [ ] Create database initialization script
-  - [ ] Add proper indexes on sha256 hash

+  - [x] `server_config` table: key-value pairs for server settings
+  - [x] Create database initialization script
+  - [x] Add proper indexes on sha256 hash
 
 ### 1.3 nginx Configuration
-- [ ] Configure nginx for static file serving
-  - [ ] Set up location block for `GET /<sha256>` pattern
-  - [ ] Configure proper MIME type detection
-  - [ ] Add proper headers (Cache-Control, ETag, etc.)
-  - [ ] Handle 404s gracefully when blob doesn't exist
-  - [ ] Configure FastCGI pass-through for non-GET requests
+- [x] Configure nginx for static file serving
+  - [x] Set up location block for `GET /<sha256>` pattern with extension support
+  - [x] Configure try_files directive for multiple extension fallbacks
+  - [x] Configure proper MIME type detection
+  - [x] Add proper headers (Cache-Control, ETag, etc.)
+  - [x] Handle 404s gracefully when blob doesn't exist
+  - [x] Configure FastCGI pass-through for HEAD and non-GET requests
 
 ### 1.4 Basic HEAD Endpoint
-- [ ] Implement FastCGI handler for `HEAD /<sha256>`
-  - [ ] Query database for blob metadata
-  - [ ] Return proper headers (Content-Type, Content-Length, etc.)
-  - [ ] Return 404 if blob doesn't exist
-  - [ ] Add server timing headers for debugging
+- [x] Implement FastCGI handler for `HEAD /<sha256>`
+  - [x] Query database for blob metadata (single source of truth)
+  - [x] Extract SHA-256 from URL (strip extensions)
+  - [x] Return proper headers (Content-Type, Content-Length, etc.)
+  - [x] Return 404 if blob doesn't exist in database
+  - [x] Add server timing headers for debugging
 
 ### 1.5 Testing & Validation
-- [ ] Create test blobs with known SHA-256 hashes
-- [ ] Verify nginx serves files correctly
-- [ ] Verify HEAD requests return proper metadata
-- [ ] Test with missing files (404 responses)
+- [x] Create test blobs with known SHA-256 hashes
+- [x] Verify nginx serves files correctly with extension support
+- [x] Verify HEAD requests return proper metadata
+- [x] Test with missing files (404 responses)
+- [x] Test HEAD requests with and without extensions
 - [ ] Performance test with large files
