+## N-dimensional dependency-space formalism
+
+This backlog item is a decomposition of [B-0824](B-0824-package-manager-of-package-managers-n-dimensional-dependency-space-holographic-projection-ai-rate-continuous-upstream-negotiation-aaron-2026-05-26.md).
+
+### Problem
+
+Today's package managers (Maven, npm, apt, Helm, etc.) each operate in their own 2D-projection of the dependency space (e.g., dependencies × versions). The true substrate Ace operates over is N-dimensional. Ace needs to operate on the full N-D space, not just a 2D projection.
+
+### Task
+
+Formalize the N-dimensional dependency space. This includes:
+
+1. **Axis Enumeration**: Enumerate the axes of the dependency space. This is not expected to be exhaustive, but should include the most important axes.
+    * Dependency relation (depends_on, conflicts_with, provides, replaces)
+    * Version (semver, range, pin)
+    * Cardinality (cluster-singleton, N-allowed)
+    * Namespace scope (cluster, namespace, per-consumer)
+    * Multi-tenant (cross-tenant isolation strategy)
+    * Multi-use (intra-tenant use-axis)
+    * Time (revision history, migration phase, rolling-upgrade window)
+    * Cross-PM (jar inside Docker inside Helm inside ArgoCD)
+    * Security posture (signed, sbom-verified, vuln-scan-status)
+    * Operator policy (environment, org-policy, compliance-tier)
+2. **Documentation**: Create a document that formalizes the N-dimensional dependency space, its axes, and how it relates to existing 2D package managers. This documentation will be consumed by future substrate-engineering decisions.
+3. **Composition with B-0822**: Make the composition with [B-0822](B-0822-diamond-resolution-namespace-cardinality-multi-tenant-awareness-as-third-dimension-of-shared-chart-dependency-resolution-aaron-2026-05-26.md) explicit in the documentation. The 4 properties from B-0822 are a 4-axis slice of the N-D space.
+
+### Acceptance Criteria
+
+* A document exists that formalizes the N-D dependency space.
+* The document enumerates the axes of the dependency space.
+* The document is consumable by future substrate-engineering decisions.
+* The composition with B-0822 is made explicit.
