healthyR.data vs medsim: at a glance
What is healthyR.data?
From a bundled hospital dataset to a live CMS API client.
healthyR.data supplies the data layer for the healthyverse packages. It began by shipping hospital data inside the package and now fetches from CMS and provider endpoints at call time through get_cms_meta_data(), fetch_cms_data(), and their provider counterparts. The most recent release is a single httr2 compatibility fix.
What is medsim?
medsim is turning simulation runs into auditable artifacts, not just fast ones.
medsim is a young Monte Carlo harness for mediation-analysis simulation studies, first tagged in May 2026 and already at 0.5.1. The last two releases moved the package's center of gravity from running simulations to proving a run is trustworthy: chunk provenance headers, a single-SHA assertion across chunks, and a pilot-subset positive control. The statistical work sits in the missing-data line added in 0.2.0 — Fleishman non-normal generators, rate-calibrated MCAR/MAR/MNAR amputation, and a validated D4-stacked MBCO estimator.

From a bundled hospital dataset to a live CMS API client.
◆ Current state
healthyR.data supplies the data layer for the healthyverse packages. It began by shipping hospital data inside the package and now fetches from CMS and provider endpoints at call time through get_cms_meta_data(), fetch_cms_data(), and their provider counterparts. The most recent release is a single httr2 compatibility fix.
◆ Where it's heading
The 2023 release added roughly twenty current_*_data() accessors, one per CMS measure file - a wide but static surface. The 2024 releases replaced that approach with metadata lookup plus generic fetchers, then taught the fetchers to handle CSV, Excel, and ZIP payloads rather than API responses alone. The package's weight has moved from what it ships to what it can retrieve.
◆ Prediction
With the fetch layer generalised, the next visible work is more likely record-limit and error handling around httr2 than further per-measure accessors.

medsim is turning simulation runs into auditable artifacts, not just fast ones.
◆ Current state
medsim is a young Monte Carlo harness for mediation-analysis simulation studies, first tagged in May 2026 and already at 0.5.1. The last two releases moved the package's center of gravity from running simulations to proving a run is trustworthy: chunk provenance headers, a single-SHA assertion across chunks, and a pilot-subset positive control. The statistical work sits in the missing-data line added in 0.2.0 — Fleishman non-normal generators, rate-calibrated MCAR/MAR/MNAR amputation, and a validated D4-stacked MBCO estimator.
◆ Where it's heading
The arc is toward defensible HPC runs: each 0.5.x gate closes a way a cluster job could silently produce wrong output, and 0.5.1 extends the same suspicion to the estimator itself by exposing the branch disagreement the standard ARIV averages away. Releases are cadenced against discovered defects rather than a roadmap — 0.5.0 cites seven findings from a pre-integration review, and 0.5.1 cites an adversarial review of 0.5.0. The audit surface is widening faster than the method surface.
◆ Prediction
The collapse-audit exclusion list has now been patched twice for method-specific diagnostic columns, so the next likely move is a contract letting methods declare their own discrete fields instead of medsim naming them centrally.
