The Appraisal · a public, permanent record
Predictions, graded in public.
Astrology's oldest credibility problem is that nobody keeps score. We do — in the discipline K. N. Rao's school demanded of astrologers, made tamper-evident with cryptography. Every prediction is pre-registered on a hash chain before its window opens, graded against confirmed outcomes, and scored against random chance. The result is published here, flattering or not.
The live scoreboard
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.

stores an anonymized subject digest, the predicted domains, the window, and the hashes — never birth
