How can a chart calculation be audited?
An auditable chart retains canonical inputs, source and software versions, intermediate conventions, uncertainty decisions, outputs, and a digest that changes when any covered field changes. The digest proves byte-level integrity of that declared bundle; it does not prove that the input event was genuine or that an interpretation predicts outcomes.
Direct answer
An auditable chart retains canonical inputs, source and software versions, intermediate conventions, uncertainty decisions, outputs, and a digest that changes when any covered field changes. The digest proves byte-level integrity of that declared bundle; it does not prove that the input event was genuine or that an interpretation predicts outcomes.
Practical use
What to do with this answer
Export the calculation contract and reproduce it independently before examining interpretation. Treat missing versions, hidden defaults, or a digest that cannot be recomputed as provenance failures.
Distinctions to preserve
- Integrity of a bundle versus truth of its contents
- Calculation provenance versus source-event provenance
- Reproduction of arithmetic versus validation of interpretation
Limitations
- A hash cannot reveal whether an omitted input mattered.
- Independent reproduction requires the same declared algorithms and data versions.
Authority graph
Which existing contracts carry the answer
These linked pages carry the underlying definition, method, or tradition record and its own sources. This page preserves their boundaries rather than becoming a new source of independent authority.
Reproducibility digests and calculation provenance →
Establishes: A digest is a cryptographic hash of canonical serialized data. It detects change but does not by itself prove that the data were true.
Boundary: A valid digest proves integrity relative to its hashed bytes, not scientific validity or authorship.
Ephemeris and software versioning →
Establishes: An ephemeris result depends on the numerical model, data release, software implementation, configuration, and fallback behavior.
Boundary: Using a respected ephemeris does not validate claims derived from astrological labels.
Evidence attachment fingerprinting without content retention →
Establishes: Hash the attachment bytes in memory, validate media type and size limits, retain the SHA-256 digest and bounded metadata, and discard content unless a separate consent and retention policy authorizes storage.
Boundary: The method does not establish valuation, investment return, legal status, revenue, survival, market adoption, or a guaranteed business outcome, and it is not evidence that astrology predicts organizational events.
