# Life-Trajectory Harm **Entity class:** Cumulative human harm **Domains:** Security systems / opportunity / family / work / mobility ## Definition **Life-trajectory harm** occurs when repeated security-system consequences reorganize the future path of a person or household. The harm is not one delayed flight, one search, one account review, or one denied credential. It is the compounding loss of mobility, work, education, relationships, health, money, time, reputation, and future opportunity produced by the continuing state. The causal structure is: **erroneous state → repeated friction → defensive adaptation → foregone opportunities → family and network effects → reduced future options → altered life path** This harm is difficult to see institutionally because each organization observes only its own event. An airline sees a boarding decision. A consular system sees a visa record. Police see one encounter. An employer sees missed travel. A school sees absence. A family sees the whole accumulation. The record of [[wiki/Rahinah Ibrahim|Rahinah Ibrahim]] is unusually complete. The Ninth Circuit described arrest and humiliation at the airport, inability to return to Stanford to pursue her degree, permanent exclusion from the United States without warning after thirteen years, inability to attend her own trial, interference with her daughter's attendance as a trial witness, and litigation costing more than $3.6 million. These were downstream consequences of a nomination error the government ultimately conceded should never have placed her on the No Fly List. Life-trajectory harm is the human meaning of [[wiki/Cumulative Downstream Burden|Cumulative Downstream Burden]]. It is also the extreme form of [[wiki/Opportunity Foreclosure|Opportunity Foreclosure]]: the security state does not merely interrupt one action; it changes which futures remain practically available. ## Relationships - **root mechanisms:** [[wiki/Watchlist Misidentification|Watchlist Misidentification]], [[wiki/Distributed Erroneous State|Distributed Erroneous State]], and [[wiki/Identity-Rooted Error Amplification|Identity-Rooted Error Amplification]]. - **opportunity layer:** [[wiki/Opportunity Foreclosure|Opportunity Foreclosure]], [[wiki/Counterfactual Opportunity|Counterfactual Opportunity]], and [[wiki/Right Not to Be Finalized by a Forecast|Right Not to Be Finalized by a Forecast]]. - **measurement:** [[wiki/Cumulative Downstream Burden|Cumulative Downstream Burden]] and [[wiki/The Second Error Function|The Second Error Function]]. - **canonical case:** [[wiki/Rahinah Ibrahim|Rahinah Ibrahim]] and [[wiki/Ibrahim v.
