…ole output - Add bounds checks in bbl_format.rs to prevent array access panics - Restore debug frame analysis output for I-frames and P-frames - Fix CSV export logic to show console output regardless of --csv flag - Add comprehensive test suite (13 tests) covering core functionality - Improve user experience with always-visible statistics and export info - Update clippy compliance with is_some_and() for better idiomatic Rust Resolves critical runtime panics and restores expected console behavior.
- Fixed time field prediction using PREDICT_PREVIOUS logic for stability - Fixed PREDICT_INC parameter passing to avoid corrupted current_frame values - Fixed I-frame inclusion in debug_frames for proper CSV export - Fixed CSV export to use actual parsed values instead of frame positions - Fixed previous2_frame passing for straight-line prediction algorithms - Improved data quantity from 43 to 34,917 rows (81,000% improvement) - Time values now in correct microsecond scale (40,581,608...) vs wrong (1,2,3...) - Resolved clippy warnings for format string efficiency Remaining issues: - LoopIteration sequence still chaotic (needs frame collection/ordering fix) - Data quantity 86% below reference (34,917 vs 260,420 rows) - Frame filtering may be too aggressive
CRITICAL DISCOVERY: C reference outputs frames in strict parse order without sorting. Timestamp sorting was causing: 1. Chaotic loopIteration sequences (8,4,15,1,2,3,7...) → Sequential (1,2,3,4,5...) Results: - Data quantity: 34,917 → 217,971 rows (vs 260,420 reference) - LoopIteration: Sequential with minor gaps (major improvement) - Time values: Correct microsecond scale maintained - Consistent across multiple BBL files This matches C reference architecture exactly - frames output immediately after parsing without collection/sorting, preserving natural sequential order.
- Remove incorrect 100% completion claims from README.md - Update README to basic project description without status reports - Replace OVERVIEW.md with proper 0/9 work-in-progress status - Remove historical references and achievement claims - Maintain technical accuracy while reflecting ongoing development
CRITICAL BUG FIX: debug_frames.insert('I', Vec::new()) was clearing
the I-frame vector on every new I-frame, keeping only the last one.
BEFORE: CSV collecting 1 I-frames (only last frame with loopIteration=1734)
AFTER: CSV collecting 18 I-frames (all frames starting from loopIteration=0)
RESULTS:
- ✅ CSV now starts with correct loopIteration=0 and timestamp=62694011
- ✅ Collects all I-frames instead of just the last one
- ✅ Proper sequential frame progression
- ✅ Matches blackbox_decode initial frame structure
IMPACT: Resolves major data corruption in CSV export where most
I-frames were lost, causing plots to show incorrect gyro/motor data.
- Updated frame sorting to sort by loopIteration first, then timestamp - Fixed loopIteration sequencing to be consecutive (0,1,2,3,4...) - PNG generation works and produces valid analysis plots - STILL BROKEN: Time progression, motor scaling, accelerometer values, flight mode flags - Data conversion pipeline has systematic scaling/formatting bugs - Structure correct but numeric values corrupted (~70% motor scaling error) - Branch: 20250625_fix_export_data_quantity - Voltage scaling issue acknowledged but not prioritized
- Removed loopIteration sorting which was breaking data values - blackbox_decode.c doesn't sort by loopIteration, only by timestamp - This matches the C reference behavior for chronological output - Motor values, accelerometer, and flags issues persist (not sorting-related) - Data conversion pipeline still has scaling/formatting bugs in bbl_format.rs
