Direction and Observation Casting
This guide explains direction and observation casting: which inputs count, how they map to a hexagram and moving line, and whether OpenFate currently supports the method.
The later-heaven observation rule takes the observed object as the upper trigram, its direction as the lower trigram, and object number + direction number + hour number for the moving line. Observation input and later omen interpretation must stay separate.
Record the observer position, compass convention, object chosen, and local hour before calculation. Moving the origin or choosing a different object after seeing the result invalidates the check.
Declare the casting method before calculating. Record the question, permitted inputs, represented instant and timezone when relevant, pre-modulo totals, remainder mapping, line order, and methodology version.
How does Direction and Observation Casting work?
Explain Direction and Observation Casting, reproduce its check, and identify the point where evidence ends.
How can you verify Direction and Observation Casting?
Reproduce Direction and Observation Casting from the recorded inputs, then label the result under the page's primary topic, “direction and observation casting.” Preserve the first reading and disconfirming evidence before revising it.
What does Direction and Observation Casting include and exclude?
Use Direction and Observation Casting for this topic's definition, rule, reproducible check, source scope, and stopping condition. These pieces belong together because each limits how the answer should be read.
What are the limits of Direction and Observation Casting?
Use the result as a structured hypothesis. Keep observable evidence, uncertainty, and a reversible next action beside it.
What evidence supports Direction and Observation Casting?
Direction and Observation Casting cites 2 sources only for the claims each source can support. Primary transcriptions establish transmitted wording; scholarship and bibliography establish history; OpenFate code establishes current repository behavior only.
