Execution attempt

← Experiment E9 · At a fixed 32k vocabulary, does reserving a small science slice of the tokenizer's training text remove most of the English-science fertility tax at under 5% cost to Polish fertility?

Execution attempt · A86 · rerun

Re-runs step 02 with --g3 after Amendment 2: the five built arms are skipped and the existing retrain is reused; model content with the output path cleared and tokenizer.json are identical, raw model bytes are not. The run was not logged; its result is recorded only in the tokenizers manifest, whose original lists the unscrubbed model digests.

Succeeded · Registered by @stw2 via agent. Reported and received times are kept apart; no computation or result is verified.

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.
