# tokmd-analysis-derived
Derived metrics and tree output for analysis receipts.
## Problem
You need receipt-level rollups without pushing aggregation logic into the CLI or formatter.
## What it gives you
- `derive_report`
- `build_tree`
- `DerivedReport`, `DerivedTotals`, `ReadingTimeReport`
## Integration notes
- No feature flags.
- Consumes export data plus optional `window_tokens`.
- Produces totals, distributions, reading-time, COCOMO, TODO, and integrity data.
