Included runs

C · Location-neutral control · cmuhhmr610003l604lkpoqzhs

Scope is Top 10. Historical runs are not mixed into these figures unless listed above.

In the controlled recruitment experiment, personas began from an identical visible world.

Following different observed interaction sequences, Persona A and Persona B received measurably different refreshed exposure sets, while the neutral control remained unchanged.

The neutral control returned Visible World Divergence 0.000.

• Three synthetic personas started from an identical visible world of 24 JOB-* listings.
• Persona A recorded AI / GenAI clicks, then refreshed.
• Persona B recorded Cybersecurity clicks, then refreshed.
• Persona C recorded no item clicks and refreshed as an untouched control.
• Exposure, actions, and comparisons are stored as evidence records.

Personas began from an identical visible world of 24 JOB-* listings before recorded interactions.

None recorded for this selection.

Not available for this selection.

C — Neutral Control began from the common baseline Top 10. No recorded item clicks preceded the refresh. The untouched control retained an identical observed visible world. Top-10 Jaccard overlap between the initial and refreshed exposure sets was 1.00. Visible World Divergence was 0.000. These observations describe a change in exposure. They do not establish an unknown external ranking mechanism.

  How an external recruitment platform would weight equivalent interactions.

  Whether the same sequence would produce a persistent effect over multiple days.
• UNKNOWNNOT ESTABLISHED
  Whether exposure would recover after behavior changes.

  KNOWN IMPLEMENTATION RELATIONSHIP: the controlled lab recommendation engine is explicitly coded to use interaction state.
• UNKNOWNNOT ESTABLISHED
  This known implementation relationship is not an experimental causal claim about an external platform.
• UNKNOWNNOT ESTABLISHED
  For external systems, causal status defaults to NOT ESTABLISHED.
• UNKNOWNNOT ESTABLISHED
  The email click is not established as the cause of later ranking changes.

• This is a controlled synthetic environment.
• The mock recommendation engine is deterministic and owned by SHIRO & Co.
• Personas are synthetic experimental variables, not claims about real individuals.
• No inference about real individuals is licensed by this report.
• No external-platform ranking mechanism was observed.
• OPENED is an observed email-open event. It does not necessarily represent human reading or engagement.
• Visible World Divergence is an internal experimental comparison metric. It is not a validated industry standard.
• Association language in this report must not be generalized into causal claims about external systems.
