What is MotherDuck?

MotherDuck keeps wrapping its agent-native stack in the plumbing enterprises need to adopt it.

The two capabilities MotherDuck has bet on — Flights for Python pipelines that MCP agents can drive, and Guides for the organizational context those agents read automatically — are now surrounded by the operational layer that makes them usable at scale: RBAC, org-wide admin visibility, regional availability in Sydney and Tokyo, runtime limits. The August 14 release adds the client surface that was still missing, a CLI covering auth, queries, Dives and Flights with scriptable output.

What is tern.mmrm?

An MMRM tabulation package that has published nothing since its 2024 CRAN releases.

tern.mmrm wraps mixed models for repeated measures into the tern tabulation and plotting layer used by teal clinical modules. The visible history ends with three CRAN releases in mid-to-late 2024; before that the feed carries only automated version bumps from 2022, three of which have just been backfilled into the record. The most recent substantive change adds axis limit arguments to the LS-means plot.

MotherDuck keeps wrapping its agent-native stack in the plumbing enterprises need to adopt it.

◆ Current state

The two capabilities MotherDuck has bet on — Flights for Python pipelines that MCP agents can drive, and Guides for the organizational context those agents read automatically — are now surrounded by the operational layer that makes them usable at scale: RBAC, org-wide admin visibility, regional availability in Sydney and Tokyo, runtime limits. The August 14 release adds the client surface that was still missing, a CLI covering auth, queries, Dives and Flights with scriptable output.

◆ Where it's heading

The pattern is consistent: ship an agent-facing capability, then spend the following weeks making it governable and reachable. Iceberg interoperability keeps widening — Databricks-managed tables, Cloudflare R2 as a persisted catalog, server-side attach — which positions MotherDuck as a compute engine over catalogs it does not own. The CLI extends the same logic to automation: anything the UI can do should be drivable from a script or a CI job.

◆ Prediction

Expect the CLI to leave preview with Flights and Dives management as its centre of gravity, and Guides to follow the same governance path Flights took — org-level controls, roles, and visibility rules layered on after the capability lands.

ANALYTICS
0.0

An MMRM tabulation package that has published nothing since its 2024 CRAN releases.

◆ Current state

tern.mmrm wraps mixed models for repeated measures into the tern tabulation and plotting layer used by teal clinical modules. The visible history ends with three CRAN releases in mid-to-late 2024; before that the feed carries only automated version bumps from 2022, three of which have just been backfilled into the record. The most recent substantive change adds axis limit arguments to the LS-means plot.

◆ Where it's heading

Content per release is thin and largely organisational: a maintainer change, replacing scda with random.cdisc.data in vignettes, and adapting to new {mmrm} versions. The package appears to be in maintenance, tracking its upstream dependency rather than developing independently. The 2022 entries now visible are release-automation commits, not releases in any meaningful sense.

◆ Prediction

Nothing here signals new functionality; the realistic next event is another compatibility release when {mmrm} or {rtables} changes underneath it.
