hubAdmin vs tulpaRatio: at a glance
What is hubAdmin?
The config-authoring half of hubverse, pinned to whatever the schema is doing this quarter
hubAdmin builds and validates the JSON configuration that defines a hubverse forecast hub — rounds, model tasks, output types, target metadata. It is the administrator-facing member of the hubverse family, sitting alongside the packages that read and evaluate hub data. Its release cadence is set almost entirely by the hubverse schema, which it has now tracked from v4.0.0 through v6.0.0.
What is tulpaRatio?
A Bayesian ratio-modelling package that threw out its Stan dependency and wrote its own sampler
ratiod models ratios, rates and proportions hierarchically, with the stated position that a ratio is a derived quantity and inference should run on the latent numerator and denominator processes rather than their quotient. The 1.0.0 release shipped a native HMC/NUTS backend, removing the Stan dependency that packages in this space normally take as given. Everything since has been sampler optimisation, benchmarked against the Stan implementations it replaced.

The config-authoring half of hubverse, pinned to whatever the schema is doing this quarter
◆ Current state
hubAdmin builds and validates the JSON configuration that defines a hubverse forecast hub — rounds, model tasks, output types, target metadata. It is the administrator-facing member of the hubverse family, sitting alongside the packages that read and evaluate hub data. Its release cadence is set almost entirely by the hubverse schema, which it has now tracked from v4.0.0 through v6.0.0.
◆ Where it's heading
Every release here is legible as schema-following. New schema properties become new arguments, new schema constraints become new validate_config() checks, and the package version is essentially a marker for which schema generation it can author. The one thread that is genuinely its own is ergonomics: session-level options for schema version and branch, support for in-development schema branches, and a steadily stricter validator that now catches duplicate properties and mismatched target keys before a hub goes live.
◆ Prediction
With v6.0.0 support only partially landed, the next releases most likely finish the additional_metadata migration across the remaining create_* functions.

0.0ANALYTICS
A Bayesian ratio-modelling package that threw out its Stan dependency and wrote its own sampler
◆ Current state
ratiod models ratios, rates and proportions hierarchically, with the stated position that a ratio is a derived quantity and inference should run on the latent numerator and denominator processes rather than their quotient. The 1.0.0 release shipped a native HMC/NUTS backend, removing the Stan dependency that packages in this space normally take as given. Everything since has been sampler optimisation, benchmarked against the Stan implementations it replaced.
◆ Where it's heading
The feed reads as one architectural bet followed by the work to justify it. After the native backend landed, the releases are a steady march of gradient and adaptation work — hand-coded gradients for more model families, L-BFGS mass matrix adaptation, an O2 build — each measured as a speed multiple against Stan. Coverage is tracked openly as a fraction (48 of 60 hand-coded configs), and unresolved problems are named rather than buried, including a deferred GP spatial bug.
◆ Prediction
The hand-coded gradient coverage count is the visible backlog, so the next releases most likely close the remaining configs and resolve the GP spatial issue that the benchmark release explicitly deferred.
