Work-mix over time

Share of Growth / Maintenance / Fixes over a rolling 7-day window. Reads as 'where is effort flowing right now'.

Bug flow over time

Monthly bug flow attributed to this developer. The left bar (red) is bug impact this dev authored that was addressed in the given month — combining bugs others fixed for them and bugs they fixed themselves. The right bar is fixes they personally shipped that month, split between self-fixes (overlap with the red bar) and fixes done for someone else. X-axis is fix-time, not introduction-time — the Navigara API attributes bugs backward to the author at the moment the fix lands.

Self-fix share: 47%
Bugs you introduced: 2.6
