What is qcTAF?

qcTAF is building an automated checklist for reproducible fisheries assessments, one criterion at a time

qcTAF performs quality control on TAF (Transparent Assessment Framework) analyses, the workflow standard used for ICES fisheries stock assessments. It launched in February 2026 with eight checking functions and a README listing ten criteria that define a complete TAF analysis. Three releases followed within four months, all adding checks or tightening existing ones.

What is tulpa?

The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.

tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.

qcTAF is building an automated checklist for reproducible fisheries assessments, one criterion at a time

◆ Current state

qcTAF performs quality control on TAF (Transparent Assessment Framework) analyses, the workflow standard used for ICES fisheries stock assessments. It launched in February 2026 with eight checking functions and a README listing ten criteria that define a complete TAF analysis. Three releases followed within four months, all adding checks or tightening existing ones.

◆ Where it's heading

Each release converts more of the informal completeness checklist into executable checks. February added relative-path and script-existence checks; late February added data and software declaration checks plus two new completeness criteria covering initial-versus-boot data identity and DATA.bib declarations; May added qc.any.scripts.exist() and made qc.only.relative.paths() treat /home/ as absolute. Function naming is being revised as the set grows, with renames in every release so far.

◆ Prediction

With the naming churn ongoing and criteria still being added, the next release most likely continues both. The package appears to be tracking a moving definition of TAF completeness rather than a fixed spec.

The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.

◆ Current state

tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.

◆ Where it's heading

Two moves in nine days point at the same destination: the generics conversion made tulpa extensible by downstream packages, and CRAN admission makes it installable by them. The current cadence — several tags a week, some existing only to record a measurement that produced no code change — does not survive CRAN's submission overhead, so the release rhythm has to slow whether or not the project intends it. The correctness work still clusters on the joint nested-Laplace driver, and 0.1.0 extends the same diagnostics habit with .NL_AXIS_SD_REASONS, a closed vocabulary for an outer axis whose grid does not contain its own posterior mode.

◆ Prediction

Expect tulpaObs to follow tulpa onto CRAN, since it is the consumer whose registrations the engine has spent this window unblocking, and expect the version line to move in larger, less frequent steps now that each one carries a submission.
