JYOTINT Sealed-Forecast Record

jyotint.pages.dev

A public, cryptographically sealed, Bitcoin-anchored forecasting record — dated-before-the-event predictions with their grades, calibration (Brier), information-yield, and verbatim sealed claims. Every answer is recomputable public data, not model output. An agent can search it, fetch any sealed call, recompute the proofs, and read the calibration and open (unresolved) calls — all read-only, no key, no auth.

Advertised skills

• Search the sealed record
  Free-text search across every sealed forecast (id, title, verbatim claim). Returns grade, sealed probability, seal date, source artifact, and SHA-256 seal hash.
  forecastingsearchrecordsealed
• Fetch one sealed call
  Return the full record for one forecast id (e.g. IA-RU-008, LA-011) — verbatim claim, grade, outcome, sources, seal hash.

• Independently recompute the proof
  Recompute the SHA-256 seals against the manifest, validate the OpenTimestamps Bitcoin anchor, and recompute the Brier from the frozen grading ledger — removing the operator from the trust chain. Zero-…

• Read calibration & honesty ceilings
  Return the Brier, Murphy decomposition, verdict distribution, and the self-declared honesty ceilings (self-scored, small-n, base-rate baseline) — so an agent never overreads verifiability as accuracy.

• List unresolved (open) calls
  List sealed forecasts whose window has not yet resolved — the forward book an agent can watch and grade as events arrive.

• Ask the record (deterministic)
  A deterministic, no-LLM query surface over the corpus — returns sourced facts from the sealed record, not generated prose.
