What is PESTO?

A calibration toolkit that found its core PEST++ bridge had never actually run

PESTO wraps PEST++ inversion for APSIM crop models from R. Version 0.10.0 rebuilt the PEST++ invocation layer after the maintainer found the shell-out had never executed: control variables were passed as /h :name=value, a syntax PEST++ has never accepted. Fifteen defects were present since the initial April 2026 release and shipped in every version after it. 0.10.1 followed with APSIM binary discovery via APSIM_EXE_PATH and a benchmark battery against real PEST 18, pestpp-ies 5.2.16 and native APSIM that reproduced the prior baseline at 0.0% deviation on every accuracy metric.

What is phyloatlas?

An atlas of the tree of life that keeps publishing what it got wrong, and stopped shipping the trees it does not own.

This is a curated deposit of species-level phylogenies — 264 trees across 62 partitions, 247 of them time-calibrated — paired with a species-name dictionary of roughly 638,000 standardized labels and per-tree provenance. It is moving through peer review at Methods in Ecology and Evolution, and the release stream is essentially a public erratum log: eight releases in five weeks, each reconciling the deposit against source papers, the manuscript, and its own metadata. The most recent replaced the turtle canonical with a 274-tip ultrametric chronogram after the previous tree failed time-calibration integrity checks.

◆ Current state

PESTO wraps PEST++ inversion for APSIM crop models from R. Version 0.10.0 rebuilt the PEST++ invocation layer after the maintainer found the shell-out had never executed: control variables were passed as /h :name=value, a syntax PEST++ has never accepted. Fifteen defects were present since the initial April 2026 release and shipped in every version after it. 0.10.1 followed with APSIM binary discovery via APSIM_EXE_PATH and a benchmark battery against real PEST 18, pestpp-ies 5.2.16 and native APSIM that reproduced the prior baseline at 0.0% deviation on every accuracy metric.

◆ Where it's heading

The arc runs from packaging discipline toward working software, and the ordering is unusual. Releases 0.4.0 and 0.4.1 were governance and metadata passes: citation files, code of conduct, canonical URL migration to AAGI. 0.7.0 broadened the forward-model templates to ODE, crop-growth and SEIR forms and promoted the observation schema to public API. Only at 0.10.0 did the project ground itself against the actual USGS sources and a real pestpp binary, which is precisely when the defects surfaced.

◆ Prediction

Expect the next releases to widen the real-engine test matrix - more PEST++ variants and pinned APSIM versions exercised in CI - rather than add new forward-model families, since verification is now the stated priority in every release note.

An atlas of the tree of life that keeps publishing what it got wrong, and stopped shipping the trees it does not own.

◆ Current state

This is a curated deposit of species-level phylogenies — 264 trees across 62 partitions, 247 of them time-calibrated — paired with a species-name dictionary of roughly 638,000 standardized labels and per-tree provenance. It is moving through peer review at Methods in Ecology and Evolution, and the release stream is essentially a public erratum log: eight releases in five weeks, each reconciling the deposit against source papers, the manuscript, and its own metadata. The most recent replaced the turtle canonical with a 274-tip ultrametric chronogram after the previous tree failed time-calibration integrity checks.

◆ Where it's heading

The project's defining decision is that it archives the recipe rather than the corpus. Since 1.0.3 the Zenodo deposit holds metadata, provenance, and standardization code while the tree files live at their original sources, and the same principle was applied again when the TimeTree-of-Life was removed at the TimeTree project's request and reduced to a citation. What makes the correction log unusual is its direction: partitions keep getting reclassified from dated to undated as verification confirms the source papers described chronograms they never deposited. The atlas is being built to be honest about archival uncertainty rather than to maximize coverage.

◆ Prediction

The release cadence is driven by the manuscript review cycle, so expect corrections to continue until MEE acceptance and then slow sharply; the open thread most likely to produce the next one is the remaining recoverable archival uncertainty flagged across non-Condamine dated source trees.

Frequently asked questions

What is the difference between PESTO and phyloatlas?

They serve adjacent needs but don't currently overlap on shipped themes. PESTO and phyloatlas are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.

Is PESTO better than phyloatlas?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. PESTO and phyloatlas are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
