What is eratosthenes?

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

What is Prisma?

Prisma 7's Rust-free client is the floor — every release since has been hardening the WASM stack and pulling Postgres deeper in.

Prisma is in steady-state release mode after the v7.0 cutover removed the Rust query engine in favor of a WebAssembly query compiler running on the main JS thread. Recent ORM versions have layered on what the WASM architecture made possible — query caching, fast/small compilers, savepoint-based nested transactions — alongside tooling (prisma bootstrap, prisma postgres link, Studio dark mode) that ties the ORM ever more tightly to Prisma's own Postgres offering.

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.

◆ Current state

eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

◆ Where it's heading

The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.

◆ Prediction

With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.

Prisma 7's Rust-free client is the floor — every release since has been hardening the WASM stack and pulling Postgres deeper in.

◆ Current state

Prisma is in steady-state release mode after the v7.0 cutover removed the Rust query engine in favor of a WebAssembly query compiler running on the main JS thread. Recent ORM versions have layered on what the WASM architecture made possible — query caching, fast/small compilers, savepoint-based nested transactions — alongside tooling (prisma bootstrap, prisma postgres link, Studio dark mode) that ties the ORM ever more tightly to Prisma's own Postgres offering.

◆ Where it's heading

Two parallel arcs: (1) catching up on real database semantics that the previous Rust engine couldn't easily expose (savepoints, partial indexes, query caching), and (2) productizing a turnkey Postgres path where the CLI handles provisioning, linking, and migrations end-to-end. Prisma is converging the ORM and the hosted database into a single onboarding experience.

◆ Prediction

Expect the next minor releases to keep paving the Prisma Postgres path — likely connection-pool defaults, edge-runtime-aware client builds, and tighter CI/migration ergonomics. Independent ORM users may continue to feel like a slower-moving lane while bootstrap-style commands favor the hosted DB.
