pdftoppm zero-pads the page number based on total page count:
- <10 pages: page-1.png
- <100 pages: page-01.png
- <1000 pages: page-001.png
The code hardcoded 'page-1.png' and 'page-N.png', which fails for any
multi-page document. Use filepath.Glob('page-*.png') to find the actual
output regardless of padding width.
Fixed in both ConvertToImage() (first-page preview) and the multi-page
OCR loop in ProcessDocument().
Replaces kimi-k2p5 for all vision tasks. K2.5 was outputting chain-of-thought
reasoning instead of JSON for non-English docs, requiring a fallback path.
qwen3-vl works first try, no retry needed, preserves original language correctly.
- Add 'DO NOT translate, preserve original language' to vision prompts
- Shorter/tighter JSON prompt to reduce K2.5 reasoning verbosity
- Fallback: when AnalyzeWithVision returns no JSON, do AnalyzePageOnly (plain text) then AnalyzeText (classify)
- Fallback to AnalyzePageOnly for single-page PDFs with empty/placeholder full_text
- Switch model back to kimi-k2p5 (only vision model on this Fireworks account)
- Build with CGO_ENABLED=1 -tags fts5 (required for SQLite FTS5)
