Talos Linux vs taxifydb

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.

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.

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.
