Ephemeris File Version provenance contract

What must a machine preserve for ephemeris file version?

A provenance contract for Ephemeris File Version, separating reproducible celestial computation from interpretive and predictive claims.

Bounded answer

Preserve ephemeris family, file or dataset identifier, release, checksum, coverage interval, and flags. Bind those fields to one canonical input manifest and receipt before interpreting or sharing an output.

Input contract

What must be fixed first

Canonical input manifest

Named algorithm and dependency versions

Declared units and conventions

Retention and redaction policy

Procedure

Work the decision in order

  1. 1

    Normalize the input without dropping uncertainty.

  2. 2

    Record ephemeris family, file or dataset identifier, release, checksum, coverage interval, and flags.

  3. 3

    Run the named deterministic operation.

  4. 4

    Bind inputs and outputs into a receipt.

  5. 5

    Verify the receipt independently before interpretation.

Expected outputs

  • Canonical manifest
  • Calculation or transformation receipt
  • Reproducibility and redaction statement

Refuse when

  • Naming a software library does not identify the ephemeris data it loaded.
  • Required input, unit, convention, or dependency version is absent.
  • An interpretive preference selects the computational convention after outputs are seen.

Questions this guide answers

What must a machine preserve for ephemeris file version?

Preserve ephemeris family, file or dataset identifier, release, checksum, coverage interval, and flags.

Which information must be versioned?

At minimum, preserve ephemeris family, file or dataset identifier, release, checksum, coverage interval, and flags, together with the canonical input and output digests.

When should an output be withheld?

Withhold it when naming a software library does not identify the ephemeris data it loaded. or when a required dependency cannot be identified.

Does determinism validate the interpretation?

No. Determinism makes the computation reproducible; interpretive or predictive validity requires a separate prospective evaluation.

What belongs in the receipt?

The operation, canonical inputs, units, assumptions, dependency versions, outputs, uncertainty treatment, and package digest.

Limits

  • Naming a software library does not identify the ephemeris data it loaded.
  • Reproducible astronomical arithmetic does not validate an astrological interpretation or prediction.
  • No missing number, uncertainty interval, or calculation receipt is invented.
