LARI built a small JavaScript app twice, starting from zero each time

Research question

Can an isolated candidate construct a bounded JavaScript application from its contract and tests, then reuse retained structured knowledge in a second blank workspace?

Why this matters

Cold reload and exact-record removal test whether the retained procedure mattered to this bounded construction task.

What was tested

Induce a bounded typed program bundle from local immutable tests and the project contract, serialize the candidate, and reuse it in a separate blank workspace.

Baseline

A blank workspace with zero implementation modules.

Comparison conditions

Original construction and a fresh-process reconstruction with induction disabled; exact generated-entry-point removal as a causal control.

Test environment

Isolated candidate runtime; local immutable JavaScript tests; separate blank workspace and fresh process.

Observed result

Three source files were generated; the original acceptance suite passed 12/12 twice, and fresh-process reconstruction passed with induction disabled. Removing the generated entry point restored failure.

Outcome

Isolated JavaScript candidate passed its named contract; not promoted.

Measured results

Measurement conditions: One bounded JavaScript task contract; the 12 acceptance cases were unchanged; candidate-only result.

Evaluation method

The isolated candidate started from an empty implementation workspace, ran an unchanged acceptance contract twice, then a fresh process reconstructed a second blank workspace with induction disabled; an exact entry-point ablation checked whether behavior depended on the generated program.

External model usage

Zero external-model calls.

Cold reload

Fresh-process reconstruction passed with induction disabled.

Causal ablation

Removing the generated command-line entry point restored failure.

Transfer

One JavaScript task family transferred to a second blank workspace.

Limitations

One JavaScript task family and bounded typed representation. No live web research, cross-language construction, broad transfer, production promotion, or general coding mastery was established.
