  "source": "Ask five different systems where a piece of company knowledge lives - the docs\nsite, the internal developer portal, the compliance evidence store, the infra\ninventory, an agent's retrieval index - and a normal company gives you five\ndifferent answers, in five different stores, that drift from each other the\nmoment two of them are updated separately.\n\nCogitave doesn't do that. **Cogitave Core** is a single typed property graph\nthat all of those are *projections* of - not synced copies, not separate\nstores that happen to agree today. Docs, the internal developer portal,\ngovernance and compliance evidence, infrastructure inventory, and agent\nknowledge all read from the same graph, through the same query layer, which\nis MCP-native: a human using the API/UI and an agent using MCP get *the same\nknowledge from the same model*. This is the canonical\n[Cogitave Core Architecture](../../../../core/docs/architecture.md) doc, and\nthis module - and the rest of this path - builds directly on it.\n\n## What this module teaches\n\nTwo ideas make the one-graph claim more than a slogan:\n\n- **The one-model thesis** - why one graph, not one store per domain, and what\n  that buys in exchange for the discipline it demands.\n- **The property-graph substrate** - why that one graph is specifically a\n  *labeled property graph*, what [ADR-0001](../../../../core/docs/decisions/0001-property-graph-as-substrate.md)\n  decided and rejected to get there, and what makes it fast enough to serve.\n\n## Status: read this before you build against it\n\nThe architecture doc opens by calling itself a \"Day 0 canonical spec.\"\nTreat it that way here, too. The one-graph model and its ADR are **decided** -\naccepted, not proposed - and this module teaches them as documented decisions.\nIt is not a claim that every product has finished projecting into the graph,\nand it is not a hands-on module: you will not stand up Cogitave Core here, you\nwill learn to read the spec that governs it, the same spec an auditor or a\nquerying agent relies on.\n",
