SIMULATION-FIRST CATALOG

Researchers can start from the simulation, not the lecture.

Each object is a typed JSON entry with a lesson route, lab route, run card, exports, methods, limits, and evidence notes. The v67 atlas filter adds 5 search facets so users can find the right evidence object before a new lesson is written.

RUN CARD POLICY

Fast to browse, honest about what is not running.

The site can hold hundreds of simulations because the object contract separates saved execution from future compute. Inspect exact packet states and replay requirements. Real-time SPICE, uploads, accounts, payments, comments, newsletters, and submissions stay disabled in this MVP.

EXPORT / METHODS / LIMITS / EVIDENCE

Every simulation page has the same reading order.

The same six sections keep lecture users and paper-writing users aligned: explore the phenomenon, inspect the run card, export files, read the method, keep the limits, and cite the evidence.

01

Explore

Choose the simulation object and inspect the main observable first.

02

Run Card

Conditions, knobs, outputs, and precomputed-only notice.

03

Export

Datasets, netlists, scripts, and source notes stay downloadable.

04

Methods

Extraction rules explain how each metric was made.

05

Limits

Non-claims prevent teaching data from being reused as signoff evidence.

06

Evidence

Traceable artifacts keep the result reviewable and citable.
