Shown indented so it can be read. The hash is taken over the canonical form of the same object — keys sorted by code point, no insignificant whitespace, UTF-8 rather than escaped ASCII, timestamps RFC 3339 in UTC to microseconds, decimals as their plain string form. The check below re-encodes the object canonically before hashing it, which is why an indented display cannot make it pass or fail.

Which digest recipe applies

migration 0021 salted this digest · both versions coexist in one append-only log

commitment_versionv2stated in the payload

The entry names its own version, so a reader can pick the right recipe without knowing when the salt was introduced.

sha256(canonical_json({question_id, computed_at, salt, readings})), where readings is the batch's populations sorted by population, each carrying exactly {population, method, method_version, sample_size, distinct_operator_count, value}

recompute: sha256(canonical_json({question_id, computed_at, salt, readings})) must equal series_commitment in the payload above. Take question_id and computed_at from that payload verbatim, sort readings by population, and give each reading exactly the six keys served here — the values carry their stored precision and are hashed as the decimal strings they appear as
