Samples
These are synthetic samples. They exist so that the structure of an Institute record can be examined without any partner material being disclosed. They contain no laboratory data and correspond to no real experiment, group, or instrument.
Sample A
The primary output. A claim is entered once, then linked to the evidence supporting it, the records contradicting it, the uncertainty attached to each quantity, the replication attempts, the decision state, and the revision history.

A narrow spectral feature at 4.21 arb. units indicates an unmodelled transition in the target species. Decomposed into three separable assertions: the feature exists; it originates in the sample; it cannot be assigned to a known transition.
This section carries no figure. Select a relation on an evidence record to bring its figure into view.
Synthetic demonstration for public education. Case JSI-SYN-014 describes no real laboratory, dataset, or programme.
Sample B
Produced by a measurement and uncertainty audit. Terms are separated, combined only where independence holds, and the dominant contributor is named — because that is where effort changes the interval.
A synthetic measurement chain runs from instrument to interpretation. Adjust the predefined uncertainty terms and observe the combined standard uncertainty, the expanded interval, the dominant contributor, and the interpretive state that the evidence then permits.
Interactive uncertainty budget. Combined standard uncertainty 0.023, expanded interval plus or minus 0.045, dominant contributor Environmental correction, interpretive state: Marginal.
Readout noise, reducible by averaging.
Traceability of the reference used.
Not reducible by additional averaging.
Model used to convert raw to derived quantity.
Combined standard uncertainty (quadrature): 0.023 · solid bars: systematic · dashed outline: random
Marginal
The claimed effect and the expanded uncertainty are comparable. A stronger constraint is required before interpretation.
Constructed for demonstration. Contains no laboratory data.
Terms are combined in quadrature, which assumes they are uncorrelated. The chain diagram marks the dominant contributor. The interpretive state is derived by comparing a fixed claimed effect of 0.052 arb. units against the expanded uncertainty at coverage factor k = 2.
Systematic terms are shown as solid bars; random terms are outlined. Only random terms fall with additional averaging.
Metrological reasoning decides whether a claim is interpretable at all. It is not a formality applied after the physics.
Synthetic chain constructed for public methods education.
With animation disabled the sliders and readouts behave identically; no value is conveyed by transition.
Sample C
Produced by a replication design review. Attempts are recorded as a structure with their independence and sensitivity stated, so that failure to reproduce is never silently treated as falsification, and dependent agreement is never counted as confirmation.
Attempts are recorded as a topology rather than a count. The distinction between failure to reproduce and evidence of falsification is maintained explicitly, as is the distinction between independent replication and dependent agreement.
Replication tree with six nodes: original observation, independent replication, partial replication, failed replication, methodological divergence, and a superseded attempt. Currently selected: S₃ failed replication.
Constructed for demonstration. Contains no laboratory data.
Node shape and line style carry the classification, so the topology remains readable without colour. A failed replication with demonstrated sensitivity is evidence against the claim; a failed replication without established sensitivity is uninformative.
Sensitivity of each attempt is stated in the node record, because a null result without sensitivity is not interpretable.
Failure to reproduce and evidence of falsification are never treated as synonymous.
The full topology renders statically; selection is available by keyboard through the node list.
Structure
All three samples on this page are synthetic. Identifiers, values, instruments, and attempts in them are constructed for demonstration only.
