Execution attempt

← Experiment E12 · When Qwen2.5-1.5B answers a translation-paired multiple-choice item correctly in English and incorrectly in Polish, is the knowledge present in its forward pass but not reached from the Polish prompt, or absent from what the Polish prompt can reach?

Execution attempt · A122 · planned

Runs the patch harness smoke gates on Qwen2.5-1.5B: self-identity, byte-identical repeat, and calibration of every benchmark and anchor at source layer 23 into target layer 13.

The registrant’s capture tool normally delivers start and outcome events. Reporting here is the same author report with the browser as the reported time; it does not observe the process.

This attempt has a delivered outcome. A new execution is a new attempt.
