What is silx?

silx settles into maintenance a release after its PySide6 migration

silx is in the quiet phase after a generational release. 3.1.1 is a single fix to FitWidget loading a fit function from file. The release before it, 3.1.0, was the first real feature work since the migration - asinh axis scaling, twilight colormaps, and dark-theme icons - and 3.0.1 was similarly small. The 3.0.0 cut that reset the Qt binding and Python floor still defines what the line is doing.

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.

silx settles into maintenance a release after its PySide6 migration

◆ Current state

silx is in the quiet phase after a generational release. 3.1.1 is a single fix to FitWidget loading a fit function from file. The release before it, 3.1.0, was the first real feature work since the migration - asinh axis scaling, twilight colormaps, and dark-theme icons - and 3.0.1 was similarly small. The 3.0.0 cut that reset the Qt binding and Python floor still defines what the line is doing.

◆ Where it's heading

The cadence has slowed markedly since April, and the content has shifted from structural change to plotting and colormap refinement. That is the expected shape after a binding migration: downstream beamline code needs a stable target, so the project trades feature velocity for a quiet surface. The gap between 3.0.1 in May and 3.1.0 in August is the clearest signal of the deliberate slowdown.

◆ Prediction

Expect further point releases servicing the plotting and fitting widgets rather than another structural change, with feature work continuing to arrive in the 3.1.x minors rather than patches.

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.
