    elucora_captureFreeze proof of what a web source actually served, before quoting or acting on it. Returns a signed receipt that anyone can verify offline without trusting Elucora. Proves what was served and when, not that the content is true. Sends a network request to the supplied source and consumes receipt quota.
    elucora_attestProve a piece of content existed at a point in time by sealing its SHA-256 hash. Use when you already hold the bytes — a model output, a tool result, a document. Elucora records that you submitted this hash and when; it does not prove where the content came from or that it is true, because Elucora never saw the source. To prove what a web source served, use elucora_capture instead. Consumes receipt quota.
    elucora_get_receiptFetch an evidence receipt by ID: the source it covers, the exact passage or field that was sealed, the current signature result, and its transparency log and Bitcoin anchor state. Needs no credentials.
    elucora_verifyCheck whether an evidence receipt is genuine and unaltered, and what source bytes it covers. Use this before relying on a receipt produced by someone else. Needs no credentials.
