Tradition-comparison decision map

Hellenistic–Jyotiṣa decision map

Compare documented systems by source, frame, chart type, and rule semantics without manufacturing a hybrid.

Required inputs

Named traditions and versions

Rights-cleared source passages

Coordinate-frame declarations

Technique names

Comparison axis

Ordered execution

Work the protocol

  1. 1

    Verify that both traditions have evidence for the technique.

  2. 2

    Separate shared geometry from rule semantics.

  3. 3

    Map similar terms without declaring identity.

  4. 4

    Record agreements and disagreements symmetrically.

  5. 5

    Require prospective testing for performance claims.

Outputs

  • Typed correspondence map
  • Unsupported-equivalence list
  • Evaluation requirements

Done only when

  • Every correspondence cites both sides.
  • Missing evidence remains missing.
  • No blended rule is emitted.

Fail closed

Refusal conditions

  • A technique exists on only one side.
  • Translation similarity becomes historical identity.
  • One tradition’s rule fills the other’s gap.
