Your page generator, GBP, citation network, schema graph, and SEM platform each show different hours for store #47. One canonical record. Eleven consumers.

The multi-location data layer is mature. Yext + SOCi + Rio SEO + Sterling Mesh + Brandify + Synup + Surefire Local each ship strong primitives at the directory-sync + GBP + citation + reputation surface. Each is excellent at its core. The enterprise MDM layer is mature too. Informatica MDM + Reltio + SAP MDG + Profisee + Stibo Systems each ship strong primitives at the customer-master + product-master + vendor- master surface across enterprise data domains. The 11-agent fan-out across 5 marketing-ops swarms, the per-vertical schema evolution, the event-driven propagation respecting each consumer’s native SLA, and the audit-trailed conflict- resolution policy are operator-side wiring above whichever stack you license.

The pipeline is six stages. Ingest — change events flow in from POS, CMS, HR system, license registry, and operator input through the same upstream change-event emitter pattern. Adapt — incoming source values are normalized into the master schema (hours into ISO format, addresses into USPS-canonical format, services into the per-vertical taxonomy, license status into the per-state registry format). Resolve — conflict- resolution policy fires before any conflicting value reaches the master record; per-field source priority (operator input beats POS beats CMS beats HR beats license registry) decides which source wins; tied cases route to a reviewer with the conflicting values + their provenance attached.Validate — the candidate record passes through the per-jurisdiction compliance overlay before publish. Version — every accepted change bumps the master-record version + emits an audit-trail entry with the change diff + source + reviewer (if any).Sync— the new version fans out to all 11 consumers via each consumer’s native API at each consumer’s native SLA (sub-second to GBP via its real- time API; sub-minute to schema graph + page generator; sub- hour to SEM platforms with batch ingest windows + social- content schedulers).

Drift surfaces in the conflict-resolution log within the publish cycle, not weeks later via customer service. The question changes from “which system has the truth” to “which version of the master record was published at 14:00 last Thursday” — and the audit trail answers in a query.

The customer-calls-store-and-finds-it-closed pattern stops being a Monday-morning escalation. The Sunday-hours change in store #47 fans out to all 11 consumers by Wednesday afternoon — page generator + GBP + schema graph + SEM + social + the rest — and the customer who looks Sunday morning sees the same hours the door enforces.

The which-system-has-the-truth debate stops being a recurring meeting topic. When marketing-ops + the listings team + the SEM team + the schema team all argue over store #47’s hours, the master-record audit trail answers in a query — version v74 published Thursday at 14:03; source: district- manager operator input; conflict-resolved against POS Wednesday at 09:12.

The manual-re-entry tax on every per-location attribute change stops being a structural cost. The team no longer budgets ops time to re-enter every per-location update into every downstream system. The event fires once; the master record updates once; the fan-out runs once.

The new-store launch stops being a three-week propagation project. New-location day-zero fan-out completes across all 11 consumers inside a published window. The page is up; the GBP is live; the citations are submitted; the schema is emitted; the SEM is bid-eligible — all by the end of the publish cycle, not staggered across three weeks of consumer- by-consumer onboarding.
