Sealed Catalog V1

Client-facing, deterministic catalog output from Sovrient’s measured-event pipeline. This feed is designed for integration into existing model workflows without model rewrites: same event parameters, now with replayable evidence context and hash integrity.

What This Is

Deterministic catalog export from date-bound `ms_zones` + `dsd` inputs.
Fail-closed publication by default when gate/admissibility requirements are not met.
Hash anchored with canonical identity hash and file-bytes SHA256 sidecar.
Immutable dated artifact guard unless explicit force override is provided.

Disclaimers define scope. Attestations prove execution.

Dated JSON

Latest may remain unchanged on non-admissible runs (fail-closed behavior).

Verify In 3 Steps

curl -fsS https://www.sovrient.com/data/sealed_catalog_latest.json -o sealed_catalog_latest.json
curl -fsS https://www.sovrient.com/data/sealed_catalog_latest.json.sha256 -o sealed_catalog_latest.json.sha256
sha256sum -c sealed_catalog_latest.json.sha256

`OK` means file bytes match the published sidecar checksum.

Integration Contract (Readable)

schema/date/generated_utc: artifact envelope and date identity.
verification: gate state, admissibility, replay hash, DSD profile/pairs/DT0, anchor state.
summary: daily counts and corroboration aggregates.
catalog[]: per-event parameters + corroboration metrics.
canonical_sha256: deterministic logical identity hash under declared scope.
