v1.6.0

🐛 Fixed

• Phantom "meter reset" in the data-quality report. A CSV export taken mid-period pads its remaining slots with 0. Because the meter columns are cumulative counters, that padding read as one enormous drop, and the per-granularity check reported a meter reset that never happened. Those trailing rows are now recognised as padding and removed at import.
  • Your totals were never wrong — the rollup already skipped negative deltas. Only the data-quality finding was spurious.
  • Zeros between real readings are left alone: those are a meter dropout, already handled separately.
  • A row counts as padding only when every value column is absent or zero, so a genuine zero reading in one column (an empty battery's state of charge, for example) is never mistaken for it.
  • The number of rows dropped is logged on import.

• DESIGN_SPEC.md §3.3 now documents export padding at both ends of a file — the leading collapse-to-anchor and this new trailing removal — and why each is lossless.
