Research direction

Open workshop/23-ab-experiments.md and inspect the two conditional blocks and the variant selection explanation and checkpoint named in the issue. Compare the wording with the templating and A/B experiments references linked in the report. Done when both closing tags use the documented syntax and the text describes random tie breaking accurately.

Description

documentation

Workshop file reviewed

workshop/23-ab-experiments.md

Problem 1 — invalid templating syntax

The file uses {{#endif}} to close conditional template blocks, for example:

{{#if experiments.output_style }}
Write according to the output_style: ${{ experiments.output_style }}.
...
{{#endif}}

This appears twice. {{#endif}} is not valid gh-aw templating syntax and will not close the conditional block.

Problem 2 — incorrect tie-break description

The file states:

On each run, gh-aw picks the variant with the lowest invocation count so far (ties are broken by first-in-array order), then saves the updated counts and uploads them as the experiment artifact.

and the related checkpoint item:

You can predict and verify third-variant assignment order from lowest-count selection with first-in-array tie breaks

Current correct syntax

Per the live gh-aw templating reference (https://github.github.com/gh-aw/reference/templating/), conditional blocks are closed with {{/if}}, not {{#endif}} — confirmed example: {{#if expression}} ... {{/if}}.

Per the live A/B experiments reference (https://github.github.com/gh-aw/experimental/experiments/, "Statistical balancing" section):

If multiple variants are tied, including on the first run, one of them is chosen at random.

Tie-breaking is random, not deterministic first-in-array order, so the exact third/fourth/fifth-run assignment cannot be reliably predicted when counts are tied.

Suggested fix

  1. Replace both occurrences of {{#endif}} with {{/if}}.
  2. Update the explanation to: "gh-aw picks the variant with the lowest invocation count so far (ties, including on the first run, are broken at random)".
  3. Reword the related checkpoint item to reflect that tie-break order is random, so exact assignment order can only be predicted when counts are not tied.
