Joins caller-supplied vote vectors by proposal ID, encodes against/abstain/for as -1/0/1, and computes weighted cosine similarity plus exact agreement. It describes only supplied overlapping votes and does not infer ideology or future behavior.

Splits caller-supplied proposal text into sentences, scores each sentence by normalized non-stopword frequency, and returns the highest-scoring sentences in source order. It does not infer unstated intent, verify claims, or produce an abstractive interpretation.

Caps individual contributions when requested, computes each project’s raw quadratic match as (sum sqrt(contribution))² minus direct contributions, and allocates a fixed matching pool proportionally. It does not detect Sybil identities, move funds, or decide project eligibility.

Sorts unique scalar key/value entries through canonical JSON serialization and computes SHA-256. It verifies byte-level agreement with an optional claimed digest only; it does not prove block inclusion, timestamp, signer identity, or chain consensus.
