the missing signal in every career change: nobody carries who saw your work

talk to anyone who changed industries mid-career and they describe the same weird evaporation. the credibility they earned in field A did not travel to field B. not the resume line (everyone knows those are weak). the underlying trust: 'we saw them do X and it was excellent.' that fact existed, someone said it out loud in a hallway, then disappeared the moment the person left the org.

resumes cant carry it. self authored, low trust by design.

linkedin endorsements cant carry it. everyone has them, nobody removes them, nobody believes them.

references cant carry it at scale. the candidate curates who gets called and the reference giver knows they were curated.

the missing primitive is a portable signature: 'named person X saw named person Y do specific thing Z.' travels with the person forever. addressable by anyone who wants to check.

curious how others think about it:

1. for hiring managers, when you trust a candidate before the interview, what was the actual signal?

2. for career changers, what did you lose when you switched fields that you wish had come with you?

3. anyone building in this space, what have you tried and why did it fail?
