saperlipopette vs taxifydb: at a glance
What is saperlipopette?
saperlipopette turned Git disasters into practice exercises, then passed peer review
saperlipopette creates disposable Git repositories in a temporary path, each staged into a specific broken or interesting state so users can practice recovering from it. Three releases span October 2025 to May 2026, ending with a 1.0.0 that reflects completed rOpenSci-style peer review — reviewers and editors are named in the release notes.
What is taxifydb?
taxifydb found that its coverage audit was checking a hand-maintained list, not reality.
taxifydb packages taxonomic backbone databases for R, publishing prebuilt registers alongside the underlying data. The 0.1.21 release is a self-audit: the coverage checker was walking a hand-kept BACKENDS vector, so a backbone wired into the build but never added to that list was audited by nothing and reported clean, which had been the state of one backbone since it was added. The check now parses the real registration source, and refuses to run rather than audit a guessed set.

◆ Current state
saperlipopette creates disposable Git repositories in a temporary path, each staged into a specific broken or interesting state so users can practice recovering from it. Three releases span October 2025 to May 2026, ending with a 1.0.0 that reflects completed rOpenSci-style peer review — reviewers and editors are named in the release notes.
◆ Where it's heading
The package grew its exercise catalogue and then stopped to be reviewed. 0.1.1 added five exercises covering git blame, finding deleted files and lines via git log, ancestry parsing with rev-parse, and worktrees, and added switch/restore instructions alongside the checkout equivalents. 1.0.0 adds no exercises at all: it is interface polish, clarified use cases, documented workflows on every manual page, and internal renaming to align scripts with the functions they contain. Internationalisation was in from 0.1.0, with Spanish and French translations of both messages and commit messages.
◆ Prediction
With review complete and the structure documented, adding exercises is the cheap next move — the 0.1.1 batch shows the pattern. Whether more translations follow depends on contributors the entries do not name.

taxifydb found that its coverage audit was checking a hand-maintained list, not reality.
◆ Current state
taxifydb packages taxonomic backbone databases for R, publishing prebuilt registers alongside the underlying data. The 0.1.21 release is a self-audit: the coverage checker was walking a hand-kept BACKENDS vector, so a backbone wired into the build but never added to that list was audited by nothing and reported clean, which had been the state of one backbone since it was added. The check now parses the real registration source, and refuses to run rather than audit a guessed set.
◆ Where it's heading
The visible work is about closing gaps between what the build actually contains and what the checks believe it contains. Alongside the coverage fix, register artifacts are now compared against the backbones recorded in their own metadata sidecar, adding drift states the weekly workflow can open issues on. A curl bug in the same release is the same theme at a different level: setting an Authorization header replaced the header set rather than adding to it, silently dropping the Accept header that requests the asset bytes.
◆ Prediction
Expect the drift detection to keep expanding into the parts of the build that currently have no signal, since each release so far has found another place where a check was passing without looking at anything.
