The integration pattern was a response to a real constraint: each product's data lived behind that product's API, in that product's schema, with that product's assumptions baked in. Connecting two systems meant translating between their idioms, and the translation was always lossy. Productboard's idea of a feature request is not the same as Salesforce's; pushing one to the other means picking which fields survive and which are silently discarded. After two or three integrations, the resulting graph is a tangle of partial fidelities, each bridge maintained by whoever set it up.
Source-agnostic ingestion inverts the problem. Rather than connecting systems, the pattern collapses them: every input — regardless of source — is normalized to a single internal representation at ingest, with provenance preserved as metadata. A complaint filed through a feedback widget and a complaint relayed in a sales call become the same kind of object once they are inside the system, differing only in their `source` and `captured_via` fields. The reasoning layer above does not need to know which channel produced which input.
The trade-off is real. Source-specific affordances — the way Jira renders subtasks, the way Slack threads preserve conversational order, the way GitHub links to commits — do not survive normalization without explicit work. The collapsing layer has to either preserve enough structure to round-trip back to the source representation, or it has to decide that round-tripping is not a goal. Most organizations adopting this pattern choose the latter: they accept that the system of record is now the intelligence layer, and the source systems become input channels rather than first-class destinations.
What becomes possible once provenance is metadata is the operational pattern that makes this category interesting. Cross-source reasoning becomes cheap: you can ask "what are all the signals related to checkout from the last quarter" and get a unified answer across customer messages, GitHub PRs, voice notes, and Slack threads, ranked by relevance rather than by source. Cross-source deduplication becomes possible: the same complaint filed through the widget and through email collapses to one object with two attributions. The graph stops being about systems and starts being about the underlying work.
The pattern is not a free lunch. It moves complexity rather than removing it; the ingestion layer becomes the load-bearing wall, and getting the normalization right is harder than getting any single integration right. Organizations that have adopted source-agnostic ingestion describe a steeper initial setup curve in exchange for a flatter long-term maintenance curve. Whether that trade is favorable depends on how many sources the organization actually has and how much cross-source reasoning the operational layer demands.
