Holistics vs medsim: at a glance
What is Holistics?
Holistics is adding governance to the AI layer it spent the summer building.
Holistics ships small, frequent notes - often one or two sentences - covering three strands at once: AI features in Explore and Chat, as-code control over presentation through AML, and workspace hygiene like file history and dark mode. The August entries turn to the AI layer's edges rather than its capabilities, with an AI user attribute for restricting what the assistant can reach. Several entries are barely a line long, so scope frequently has to be read from the headline.
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.

Holistics is adding governance to the AI layer it spent the summer building.
◆ Current state
Holistics ships small, frequent notes - often one or two sentences - covering three strands at once: AI features in Explore and Chat, as-code control over presentation through AML, and workspace hygiene like file history and dark mode. The August entries turn to the AI layer's edges rather than its capabilities, with an AI user attribute for restricting what the assistant can reach. Several entries are barely a line long, so scope frequently has to be read from the headline.
◆ Where it's heading
The AI work has moved through a recognizable sequence: capability first with chart suggestions, then observability with AI Chat Insights for admins, and now access control with an AI-specific user attribute. Alongside it, Holistics keeps pulling presentation into AML - custom charts, theme palettes, currency formats - so the things analysts used to click are versioned as code. File history is the join between the two threads, giving every dashboard, model, and dataset its own restorable timeline.
◆ Prediction
With capability, visibility, and access control now in place for the AI layer, the next step is likely audit or policy depth - logging what the assistant answered against which data - rather than new AI surfaces.

6.3ANALYTICS
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.
