What is gcube?

gcube's recent releases are all packaging metadata, not simulation code

gcube simulates biodiversity data cubes — generating occurrence points, sampling them under configurable detection bias, and designating them to a grid — as a testbed for the B-Cubed project's indicator tooling. The visible release history is almost entirely metadata and release-automation work: Zenodo grant IDs, ROR URL fixes, publisher fields, funder and rights-holder descriptions. The simulation functionality itself is not what these entries are about.

What is vahtian?

A provenance-first corpus tool hands its verification core to agents over MCP

vahtian freezes a set of research records into a content-hashed, date-locked corpus, verifies it is untampered, and keeps a hash-chained audit ledger. It ships in Python and R with byte-identical content hashes enforced by a golden-hash test in both suites. In five weeks it went from first release to exposing its five core operations through a local stdio MCP server and registering in the MCP Registry.

gcube's recent releases are all packaging metadata, not simulation code

◆ Current state

gcube simulates biodiversity data cubes — generating occurrence points, sampling them under configurable detection bias, and designating them to a grid — as a testbed for the B-Cubed project's indicator tooling. The visible release history is almost entirely metadata and release-automation work: Zenodo grant IDs, ROR URL fixes, publisher fields, funder and rights-holder descriptions. The simulation functionality itself is not what these entries are about.

◆ Where it's heading

The February 2026 cluster reads as a package wiring up its archival identity rather than developing: four releases in four days, one of them explicitly a test of the GitHub release path. That is characteristic of research software preparing to be cited — a Zenodo DOI, correct funder attribution and a checklist-compliant description are the deliverables when the funder requires them. Substantive work on mapping functions and grid designation appears earlier and only through tutorial fixes.

◆ Prediction

With the Zenodo integration and metadata now settled, expect attention to return to the simulation functions themselves, most likely driven by what the sibling indicator packages need to test against.

A provenance-first corpus tool hands its verification core to agents over MCP

◆ Current state

vahtian freezes a set of research records into a content-hashed, date-locked corpus, verifies it is untampered, and keeps a hash-chained audit ledger. It ships in Python and R with byte-identical content hashes enforced by a golden-hash test in both suites. In five weeks it went from first release to exposing its five core operations through a local stdio MCP server and registering in the MCP Registry.

◆ Where it's heading

The direction is explicit in the project's own framing — human-first, AI-second, auditable — and the MCP server is what makes that framing operational rather than rhetorical. Rather than adding judgement, the tool is being positioned as the thing an agent calls to prove a corpus has not moved. The CiteVahti claim-source comparator, mirrored across both languages under a parity gate, extends the same idea to per-claim checking. Everything stays on the user's machine: no accounts, no telemetry.

◆ Prediction

The comparator's per-field epistemic states are the newest and least settled piece; expect the next release to extend those states or to widen the R package's distribution, which is still described as coming.
