## [2.22.1] - 2026-02-05

### Improved
- **🔍 Enhanced Semantic Analysis debugging** - Detailed logging for every field analyzed
  - Shows field type and label for each unfilled field
  - Displays whether semantic match was found or not
  - Shows profile value availability for matched fields
  - Console output format:
    ```
    [SEMANTIC] Analyzing N unfilled fields
    [SEMANTIC] Field: textarea, label: "お問い合わせ内容"
      → Matched: message (40% via label)
      → No profile value for: message
    ```

### Purpose
- Diagnose why message fields are not being detected by semantic analysis
- Identify missing profile values causing fields to be skipped
- Provide clear visibility into semantic matching decisions

## [2.22.0] - 2026-02-05

### Fixed
- **🐛 Message fields no longer filled with company names** - Generic Fallback now handles textareas correctly!
  - Root cause: Generic Fallback was treating textareas (message fields) like regular text inputs
  - Fix: Textareas now get `message` template from profile instead of cycling through company/name/email
  - If no message template available, textareas are skipped entirely
  - Prevents: "メッセージ本文に会社名が入る" issue reported by user

### Added
- **📝 More message field patterns** - Better detection for message/inquiry fields
  - WordPress CF7: Added `your-msg`, `your-inquiry`, `your-comment`, `your-content` (85% confidence)
  - Japanese Direct: Added `メッセージ本文`, `内容`, `ご質問内容`, `ご相談内容`, `詳細` (70-85% confidence)
  - Total message patterns: 4 CF7 + 8 Japanese = 12 variations

### Improved
- **🔍 Enhanced WordPress CF7 debugging** - Better field mapping diagnostics
  - Added detailed logging showing each 'your-*' field name
  - Shows whether each field is mapped or not mapped
  - Displays the target field type for mapped fields
  - Console output: `[CF7] Processing N fields: - Field name: "your-X" → MAPPED to Y`

### Technical Details
- Generic Fallback logic modified in lines 668-695
- WordPress CF7 field map expanded from 9 to 13 entries
- Japanese field map expanded from 15 to 20 entries

### Impact
- **Zero "company name in message field" bugs** - Generic Fallback now respects field context
- **Better message field coverage** - 12 pattern variations catch more forms
- **Easier debugging** - Console logs show exactly what's detected vs. not detected

## [2.21.0] - 2026-02-05

### Added

## [2.19.0] - 2026-02-04

### Added

  - Analyzes label text, aria-labels, placeholders for meaning
  - Supports Japanese and English keyword matching
  - Confidence scoring based on source quality (label > aria > placeholder)
  - Enables auto-fill on forms without pattern matches
- **🎲 Generic Fallback System (Layer 6)** - Never leave fields empty!

- **Better UX:** Users spend less time manually filling forms

### Technical Details

- Fallback strategy: Fill order matches common form layouts
- Console logs: `[SEMANTIC]` and `[FALLBACK]` for debugging

2. User B: Opens extension → Auto-downloads 15 mappings → Immediately usable
3. User B: Bulk Crawl 50 more URLs → 8 high-quality mappings → Auto-upload to cloud

## [2.16.0] - 2026-02-04

### Fixed
- **Bulk Crawler "Too many subrequests" errors 99% eliminated**
  - Root cause: Cloudflare's 50 subrequest limit applies PER WORKER INVOCATION (not concurrent)
  - Previous: 50 URLs/batch × 20 requests/site = 1000 total requests → exceeded limit on 3rd site
  - New hybrid approach: 3 URLs/batch × 16 requests/site = 48 total requests < 50 limit ✓
  - Reduced MAX_REQUESTS_PER_SITE from 20 to 16
  - Reduced BATCH_SIZE from 50 to 3
  - Optimized crawling: 12 direct paths + 1 homepage + 3 contact links = 16 requests max
  - Result: Error rate 100% → 0.96% (258 errors → 2 errors in 208 URLs)
- **Bulk Crawler hanging fixed**
  - Worker: Reduced site timeout from 60s to 20s (faster failure detection)
  - Frontend: Added 90s batch timeout with AbortController (prevents infinite waiting)
  - Math: 3 sites × 20s timeout = 60s max per batch + 30s buffer

### Improved
- **Success rate dramatically improved: 0% → 16.3%**
  - Test: 208 URLs processed, 34 successful mappings found (16.3% success rate)
  - Remaining 2 "Too many subrequests" errors (0.96%) are edge cases with redirect chains

### Changed
- Bulk crawler now processes 3 sites per batch (slower but 99% reliable)
- Level 2 links reduced from 5 to 3 for better subrequest budget management
- Site timeout reduced from 60s to 20s for faster processing

## [2.15.0] - 2026-02-04

  - Example 2: "品質へのこだわり。そしてお客様との信頼関係の構築。これらが選ばれる理由となっている"
