Added
- Added
db --latest-occurrences [DRAW_NUMBER]. - Added automatic selection of the latest complete draw when no reference number is provided.
- Added explicit inclusive historical cutoff selection.
- Added five distinct positional colors for the reference numbers on each wheel.
- Added tracing of earlier occurrences only on the same wheel.
- Added validation for missing, incomplete, ambiguous and malformed reference draws.
- Added English and Italian documentation.
Compatibility
The existing db, --digit and --number behavior remains unchanged.
The ordinary database view keeps its original ascending order. Descending chronological order is used only by --latest-occurrences.
Validation
- 191 automated tests passed.
- GitHub Actions CI passed.
- Focused CLI and database-browser suite: 30 tests passed.
- Bash and Python syntax checks passed.
- Real-database smoke testing passed.
- Automatic and explicit reference selection produced identical historical content.
- The SQLite archive remained unchanged byte-for-byte.
Research boundary
Historical occurrence tracing is strictly retrospective. It does not alter draw probabilities and does not provide a predictive or betting signal.
