What is exametrika?

A test-theory package that grew into a graphical-model toolkit, now spending its releases paying down the API debt that growth created.

exametrika is an R psychometrics package covering IRT, latent class/rank analysis, and biclustering, and it has been shipping features at an unusual clip for a CRAN package. The last two releases stopped adding capability and turned inward: 1.14.0 fixed a documented-but-never-implemented graphical-parameter passthrough, and 1.15.0 landed a full-codebase audit that corrected bugs which silently produced wrong results on missing data and 0-indexed polytomous codes. Argument names, orders, and defaults are now unified across the model functions, with every old name kept working behind a deprecation warning.

What is Lovable?

Lovable is making generated apps connector-rich and enterprise-shippable at the same time.

Two tracks run in parallel. Generated apps keep gaining third-party reach — payments, file generation and data analysis, and a connector catalogue spanning Twitch, Twilio, Linear, Telegram, Contentful, Calendly, ElevenLabs, Perplexity and Firecrawl, with voice interfaces built on top of the last of those. The second track is governance: a workspace usage dashboard, audit logs filterable by restricted project, Okta SSO and SCIM from the Okta catalogue, external-collaborator restrictions that do not require enforcing SSO on everyone, and Aikido penetration testing on every plan.

A test-theory package that grew into a graphical-model toolkit, now spending its releases paying down the API debt that growth created.

◆ Current state

exametrika is an R psychometrics package covering IRT, latent class/rank analysis, and biclustering, and it has been shipping features at an unusual clip for a CRAN package. The last two releases stopped adding capability and turned inward: 1.14.0 fixed a documented-but-never-implemented graphical-parameter passthrough, and 1.15.0 landed a full-codebase audit that corrected bugs which silently produced wrong results on missing data and 0-indexed polytomous codes. Argument names, orders, and defaults are now unified across the model functions, with every old name kept working behind a deprecation warning.

◆ Where it's heading

The arc runs from feature sprawl to consolidation. Through 1.9.0-1.13.0 the package added polytomous biclustering plots, nominal and ordinal IRM samplers, a C++ Gibbs core, and Graphical Lasso; the cost was inconsistent interfaces and correctness bugs that only surfaced under audit. The maintainer is also visibly optimizing for two external gatekeepers — CRAN's 10-minute check budget in 1.13.1, an R Journal reviewer in 1.14.0 — which suggests the package is being groomed for formal publication rather than just iterated on.

◆ Prediction

Expect the next release to continue the deprecation cleanup started in 1.15.0, likely retiring some of the old function names that have carried warnings since 1.7.0, with new modelling work paused until the R Journal submission clears.

Lovable is making generated apps connector-rich and enterprise-shippable at the same time.

◆ Current state

Two tracks run in parallel. Generated apps keep gaining third-party reach — payments, file generation and data analysis, and a connector catalogue spanning Twitch, Twilio, Linear, Telegram, Contentful, Calendly, ElevenLabs, Perplexity and Firecrawl, with voice interfaces built on top of the last of those. The second track is governance: a workspace usage dashboard, audit logs filterable by restricted project, Okta SSO and SCIM from the Okta catalogue, external-collaborator restrictions that do not require enforcing SSO on everyone, and Aikido penetration testing on every plan.

◆ Where it's heading

Lovable is answering the standing objection to AI app builders — that the output is a prototype — from both ends: giving apps real integrations so they do useful work, and giving the workspaces holding them the controls a security review asks for. Pricing rests on credits rather than seats, and recent work folds every credit type into one balance and makes usage answerable in chat. A runtime panel exposing each AI call an app makes, and TanStack Start as the default framework for Enterprise apps, point the same direction: this output is being treated as production software.

◆ Prediction

Expect the connector catalogue to keep widening and the enterprise controls to reach deployment itself — approval gates or environment separation are the obvious gaps now that audit logs, SSO and provisioning are in place.
