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 WorkOS?

WorkOS is building identity for agents while quietly fixing the sign-up funnel.

WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

◆ 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.

WorkOS is building identity for agents while quietly fixing the sign-up funnel.

◆ Current state

WorkOS ships several small entries a week, and August splits cleanly in two. One half is authentication housekeeping for human users: an Android SDK, deliverability checks that reject undeliverable addresses at sign-up, invitation acceptance counting as email verification, and a reversible SCIM proxy for migrating directory connections without downtime. The other half is agent infrastructure — Agent Registration via the auth.md protocol, and the Pipes Token Proxy that calls third-party APIs on a user's behalf without the application ever touching their token.

◆ Where it's heading

The agent work is the strategic line. Registration gives an agent an identity of its own instead of a borrowed human session; the token proxy means an application acting for a user never holds the credential. Together they describe a stack where an agent can be authorized, audited and revoked as a first-class principal. The human-auth releases are conversion and migration work — the deliverability check and SCIM Bridge both remove reasons a customer stalls — which is what a developer-infrastructure company does while its next category is still forming.

◆ Prediction

Registration and the token proxy leave scoping and revocation as the visible gaps, so expect per-agent permissions or consent surfaces next. Whether auth.md gains adoption beyond WorkOS is not something these entries can answer.
