Jackett vs whirl: at a glance
What is Jackett?
Jackett's daily release treadmill now spends commits undoing tracker removals it made days earlier.
Jackett ships near-daily auto-generated releases, each carrying a handful of tracker-definition commits: domain bumps, indexers added or removed, request delays, category tweaks. The work is entirely definition maintenance against sites that keep moving — no changes to the application itself appear in this window. Bodies are machine-generated commit lists with no prose.
What is whirl?
whirl turned script logging into a standardized provenance artifact regulators can read.
A parallel R script runner that produces execution logs, aimed at regulated analysis environments. The 0.3.0 release added write_biocompute(), emitting logs as BioCompute Objects in standardized JSON, and simplified the approved-package check to a plain package@version vector. Since then the work has been about what the log can be trusted to contain: an environment_secrets option to keep secret variables out of it, direct versus indirect package usage distinguished and highlighted against the approved list, and the same approval check extended to Python packages.

Jackett's daily release treadmill now spends commits undoing tracker removals it made days earlier.
◆ Current state
Jackett ships near-daily auto-generated releases, each carrying a handful of tracker-definition commits: domain bumps, indexers added or removed, request delays, category tweaks. The work is entirely definition maintenance against sites that keep moving — no changes to the application itself appear in this window. Bodies are machine-generated commit lists with no prose.
◆ Where it's heading
The notable pattern is reversal. 720pier was removed in v0.24.2404 and restored by revert in v0.24.2414 three days later; scenetime was added as an indexer in v0.24.2398 and dropped four days after in v0.24.2413 when an API class requirement was lifted. Round-trips like these are now a routine part of the cadence, which suggests removals are being made on incomplete information and walked back once users object.
◆ Prediction
The daily cadence continues, dominated by domain bumps and FlareSolverr dependency updates. Expect further add-then-remove round-trips as tracker sites change their access rules faster than definitions can settle.

◆ Where it's heading
The through-line is the log as evidence rather than as debugging output. Every recent addition either widens what the log proves — which packages were really used, in which language, against which approved list — or narrows what it must not leak. Setting options only through an explicit with_options argument to run() and getting renv library paths right for Quarto both point the same way: reproducible, auditable child sessions with nothing implicit.
◆ Prediction
Expect the approved-package and provenance machinery to keep expanding across languages and environments, since Python approval checks followed the R ones and both feed the same log.
