Deterministic dataset profile (CSV/Parquet)

Media-consistency grading: verifies asserted facts about media (daylight, darkness, rain, no_rain, no_earthquake, tide phase) against physics and public records for a claimed place and past time. Takes ONLY a sha256 of the media — raw media, URLs and image understanding are refused; does not authenticate media. Itemized checks with hash-attested sources and a graded score, capped by an aye/nay receipt. Verdicts cache permanently by claim hash.

Attested resolution: did an earthquake at or above a magnitude threshold occur in a named region over a past window? Resolved from the USGS feed with revision-lifecycle handling (retracted events never count; near-threshold event ids + revision timestamps pinned). Evidence bundle with source payload hashes, capped by an aye/nay receipt — never a bare boolean.

Attested resolution: will astronomical day length at a covered place meet a minimum-hours bar today or tomorrow? Computed-deterministic tier — pure celestial math, zero upstream license exposure. Deterministic per UTC day; same inputs, same claim hash. Delivered as a signed result capped by an aye/nay receipt.

Attested resolution: did measurable rain fall in a covered precinct during a stated past window? Ships as an evidence bundle — hash-attested NOAA/NWS source payloads under a signed policy manifest — capped by an aye/nay receipt. The evidence bundle is the product; the boolean is the receipt. Refusals, validation errors and coverage gaps are free; FUTURE windows are refused.

UOS Genesis machine utility: repair_validate_attest

Hash a tool description/schema and compare to a previous hash (or last seen). Returns stable|drift|unknown. Actuation OFF.

Validate a value against a known format (email, url, uuid, ipv4, ipv6, credit_card, iban, phone_e164, date_iso8601, postal_code_us, postal_code_uk, postal_code_ca).

Convert a value between units (length, mass, volume, area, speed, time, data, temperature).

Resolve an ENS name to an address, or an address to its primary ENS name.

Parse a job posting into structured JSON: title, skills, salary, requirements.

Emergency fund calculator. Multiplies monthly essential expenses by a chosen runway length (in months) to compute a target emergency savings amount. Returns 400 for invalid or out-of-range inputs.

Prime factorization of an integer via trial division, returning the full list of prime factors (with repetition). Returns 400 for non-integers, values below 2, or values above 1e12 (1 trillion).

Savings rate calculator. Divides the gap between monthly take-home income and spending by income to produce your personal savings rate as a percentage. Returns 400 for invalid or out-of-range inputs.

Tests a regular expression pattern against a string, guarded against catastrophic backtracking (ReDoS) by running the match in an isolated worker thread with a hard 100ms timeout that fails closed. Returns 400 for invalid patterns, oversized input, or a timeout.

URL encoder API. Percent-encodes text for safe use in a URL query string or path segment, handling reserved-character rules LLMs often get wrong by hand. Returns 400 if text is missing or not a string.

True-random-date generator API. Generates a bounded random date via one of: anytime, past, future, between, betweens, recent, soon, birthdate. between/betweens require "from" and "to" date strings. Accepts optional locale (default en_US). Date args must parse to a valid date with year 1000-9999. Returns 400 for an unknown field, an unknown arg key, an out-of-bound/unparseable value, a missing required arg, or an unsupported locale.

Matrix operations: multiply, transpose, determinant, and invert, for matrices up to 20x20. Uses the ml-matrix library's LU decomposition (LuDecomposition) for determinant and inversion, with a numerical near-singularity guard beyond the library's exact-singular check. Returns 400 for invalid, non-rectangular, non-finite, singular or near-singular, or oversized matrices.

Upwork freelancer fee calculator. Applies a documented tiered marginal service-fee schedule (20%/10%/5% at $500/$10,000 cumulative per-client lifetime billing thresholds) to compute take-home pay on an invoice, correctly splitting fees across a tier boundary like a tax bracket. Platform fee policies can change; verify current rates before relying on this for financial decisions. Returns 400 for invalid or out-of-range inputs.

Deterministic primality test using the Miller-Rabin algorithm with a witness set proven deterministic for all integers below 3.3x10^24, safely covering the full JavaScript safe-integer range. Returns 400 for non-integers or negative values.
