# Tour: Activity

Everything about who's contributing and how the project has moved over time.

## Authors

Per-contributor stats: commits, lines added/removed/net, a 13-week activity heatmap,
and their top-touched files. Click any contributor for the full detail modal. A
contributor with no commits in 30+ days shows a muted "Inactive" tag automatically —
no manual marking needed, though you can also explicitly mark someone inactive (for a
departed teammate whose history you still want to keep) from Settings.

## Teams

Per-team rollups once you've configured teams in Settings — commits, lines, a
commit-percentage bar, and the team lead (shown with a crown icon) if one's assigned.
Teams and team membership live in `.reikon/config.json`, committed to git, so the whole
team sees the same breakdown — see the
[config reference](../../reference/config-schema).

## Velocity

Appears once 2+ teams are configured. A multi-line chart of commits per team over time
(1 month / 1 quarter / 6 months / 1 year ranges), with per-team stat tiles: total
commits, peak week, and trend vs. the prior period.

## Quality

Commit message quality — what fraction of commits follow good practice vs. messages
flagged as low-information (too short, just a version bump, a single generic word with
no context). Poor-scoring commits get an inline "suggest a rewrite" option if AI is
connected. See [Formulas & Methodology](../../reference/formulas#commit-quality) for
exactly what gets flagged.

## Risk files

Files where one contributor owns 60% or more of the commit history, with three or
fewer total contributors and at least 5 touches — see
[the formula](../../reference/formulas#risk-files-ownership-concentration). This is
the same underlying data behind the Dashboard's contributor risk alert and the Changes
tab's reviewer suggestions.
