What it does

ai(e) sends the GraphQL mutation ExposeVariant with {input} to record that this user was shown one variant of an experiment: experimentName, variant, experimentVersion and sometimes targetingInputs (in our run, shreddit_search_expanded_composer ephemeral on home and search, and new_community_guidance_checklists_m1 enabled with r/AskReddit's id). The second call site is a GraphQL client that sends it as a persisted query, {name: "ExposeVariant", hash: "350fd154…"} (rea ev_c4793220…). It fired on every page we opened, as each experiment's feature came on screen.

What our machine does with it

log-cli's Reddit platform has only log reddit session check (the direct-API engine, with no Reddit client vendored yet) and log inspect in the account's AdsPower browser with no proxy (rule 84). Nothing waits on this call yet: inspect records it and names it in each step's exchanges.json, and SubQ reads it with the rest of the step. If log-cli acts on Reddit, these calls say which experiments our account is in, so a page that looks different between two runs can be checked against them first.

What can go wrong

All nine recorded calls answered 200 with ok: true and no errors. In the persisted-query client a 401 refreshes the token and tries again, any other status or an unreadable answer throws and is logged, and the call is abandoned after 10 s; none of this changes the page, so a failed exposure never stops a run.
