## What the ecosystem is

The mediationverse builds outward from a shared foundation — **medfit** (S7 data
classes, model extraction, fitting, and bootstrap inference) — that the analysis
packages build on. The **mediationverse** meta-package ties them together with
selective loading: only `medfit` loads by default, and `library(mediationverse)`
makes the others available without forcing every dependency into memory.

## Live status

Per-package CI/coverage/CRAN badges are maintained as a dashboard, not
duplicated here (badge walls drift fast when hand-copied into prose):

- [Package Status Dashboard](https://github.com/data-wise/mediationverse/blob/main/STATUS.md)
- Live local check: `cd ~/projects/r-packages && /rforge:status` (or `:thorough`)

## Roadmap & planning

Direction, phases, and active cross-package tasks live in the
[mediation-planning hub](https://github.com/data-wise/mediation-planning) and
the [Development Roadmap](roadmap.html) article — not duplicated here.
