Package aggregate implements the "aggregate" transform primitive: it folds every existing State.Rows entry's Values[field] down to one summary value (sum, avg, min, or max) and appends the result as a new Row.

Package describework implements the "describe-work" 🤖 transform primitive: it turns a group of raw commit titles into a one-line, natural-language description of the work — because commit subjects like "fix", "wip", or "asdf" don't belong in a timesheet or client report.

Package excludeofftime implements the "exclude-off-time" transform primitive: it subtracts recurring daily off-hours windows (lunch breaks, end-of-day cutoffs, etc.) from every session's duration.

Package groupby implements the "group-by" transform primitive: it buckets the timeline by a chosen Event field and writes one Row per bucket to State.Rows, each carrying the bucket's event count and additions/ deletions totals.

Package passthrough implements the "passthrough" transform primitive: it projects the raw event timeline directly into a display table with no aggregation, grouping, or filtering.

Package rate implements the "rate" transform primitive: it derives a dollars value for every row by multiplying its hours value by an hourly rate resolved from the run's form values, falling back to a params default.

Package registry wires every built-in transform primitive into a transform.Registry so the template engine can build a pipeline from a template's named steps.

Package sessionize implements the "sessionize" transform primitive: it clusters a timeline's events into per-owner work sessions using a gap-based heuristic, so downstream primitives can reason about continuous blocks of work instead of raw event timestamps.

Package splitbyactivedays implements a transform.Primitive that groups State.Sessions by the UTC calendar day of each session's start time and emits one aggregated Row per active day.
