Exact Transits and Orbs
Transit exactitude is the minimum angular error from an aspect target; an orb is the declared window around that target. Scope is explicit.
Overview
Distance from exact trine is 0°20′; the timestamp is exact to the ephemeris resolution, not timeless. This is the worked result for Exact Transits and Orbs; it remains conditional and does not turn geometry or timing into a verdict. The comparison method is explicit: Normalize the longitude difference, compare it with the aspect angle, solve ingress, exact, and egress times, and state body-specific orb policy.

Definition and exact scope
Transit exactitude is the minimum angular error from an aspect target; an orb is the declared window around that target.
Calculation or decision rule
Normalize the longitude difference, compare it with the aspect angle, solve ingress, exact, and egress times, and state body-specific orb policy. The receipt retains the chosen input record, reference frame, tolerance, and version, then identifies the first step where an independent recalculation diverges.
Worked case and illustrative near miss
natal ♀ 22°00′♌; transit ♃ 21°40′♈; trine target 120°; cap 2°. distance from exact trine is 0°20′; the timestamp is exact to the ephemeris resolution, not timeless.
Illustrative near miss; does not qualify: Calling a 4° contact exact because it is inside a broader interpretive orb.
School, model, and context variants
Widening an orb after seeing an event is hindsight tuning; it cannot be presented as a predeclared predictive rule.
Product, safety, and verification boundary
OpenFate connects Exact Transits and Orbs only to its implemented bounded reading; it exposes no unsupported calculator. Exact Transits and Orbs preserves contrary observations and uncertainty. It cannot replace consent, professional help, location research, or a person’s account.
