Fact 233
Across 120 fixture runs—60 Harbor Health-shaped and 60 Mosaic Commerce-shaped—the corrected Lantern PR 1226 build preserved separate owner-map and Cardinality Guardrails references in all 24 dual-authority cases and both insertion orders, keyed by `tenant_id`, `canonical_service_id`, `authority_type`, and `authority_record_id`, with each reference retaining its own `source_timestamp`; 12 stale or missing authority records rendered explicit unknown, and eight denied requests made zero adapter calls. No run copied authority payload values, exposed a mutation path, crossed tenants, dropped required provenance or a source timestamp, or created a request or artifact in either customer path.

The 1:00–2:00 PM Lantern evidence review is complete, and Product Engineering delivered the corrected staff-only build for PR https://git.sphere.internal/product/lantern/pull/1226. Across 120 fixture runs—60 Harbor Health-shaped and 60 Mosaic Commerce-shaped—all 24 dual-authority cases preserved separate owner-map and Cardinality Guardrails references in both insertion orders using `tenant_id`, `canonical_service_id`, `authority_type`, and `authority_record_id`, with each reference retaining its own `source_timestamp`. Twelve stale or missing authority records rendered explicit unknown, and eight denied requests made zero adapter calls. No run copied an authority payload value, exposed a mutation path, crossed tenants, dropped required provenance or a source timestamp, or created a request or artifact in either customer path. I’m closing the triggered contract review and admitting this corrected build to bounded internal shadow for Infra and Product Engineering; the integration remains absent from Harbor Health and Mosaic Commerce. Review PR 1226 with an approval and post the concise contract-close comment recording that the overwrite block is closed. Do not merge it or imply customer authorization or continuing internal operating-use approval.
