The Appraisal · the method, built before the record
Predictions, graded in public — once the gate opens.
Astrology's oldest credibility problem is that nobody keeps score. We built the machinery to — in the discipline K. N. Rao's school demanded of astrologers, made tamper-evident with cryptography: every prediction pre-registered on a hash chain before its window opens, graded against confirmed outcomes, and scored against random chance. Public scoring opens after counsel and independent-method review — until then this page shows the method and an empty scoreboard, not a track record. When it opens, the result is published here, flattering or not.
The scoreboard — live once public scoring opens
Loading the public ledger…
Tamper-evident, by construction
Each prediction is content-hashed and linked into an append-only chain —
H(previous link ‖ prediction). Alter, reorder, or back-date any record and
every later link breaks. The current chain head is a cryptographic commitment to the entire ledger:

How a prediction is graded
1 · Pre-registered
The engine's deterministic house-domain prediction for a chart's running Vimśottarī period is written to the ledger before the period's window — hash-chained so it cannot be edited or back-dated afterwards.
2 · Outcome confirmed
When the window closes, the chart's owner reports which life-domains real events actually touched. No outcome, no grade — unresolved predictions stay visibly open.
3 · Scored against chance
The headline metric is lift: how much better the engine did than a random predictor of the same width. Predicting many domains is held to a proportionally higher bar; predicting all twelve counts for nothing.
Methodology — in the engine's own words

stores an anonymized subject digest, the predicted domains, the window, and the hashes — never birth
data, names, or the chart.
