+# Remove Path Aliases
+
+Date: 2025-10-23
+
+Status: accepted
+
+## Context
+
+In [031-imports](./031-imports.md), we implemented path aliases using both the
+`"imports"` field in `package.json` and the `paths` field in `tsconfig.json`.
+This was done as a temporary solution because TypeScript didn't natively support
+the `"imports"` field, requiring us to maintain both configurations to get
+autocomplete and type checking.
+
+However, TypeScript has now added native support for the `"imports"` field in
+`package.json` (as referenced in the original decision's "yet" link). This means
+we no longer need the `paths` configuration in `tsconfig.json` to get proper
+TypeScript support for our imports.
+
+## Decision
+
+We're removing the path aliases configuration from `tsconfig.json` and relying
+solely on the `"imports"` field in `package.json`. This simplifies our
+configuration and aligns with the standard Node.js approach.
+
+The `"imports"` field will continue to work as before, providing the same import
+resolution functionality, but now with full TypeScript support without requiring
+duplicate configuration.
+
+## Consequences
+
+- **Simplified configuration**: We no longer need to maintain both
+  `package.json` imports and `tsconfig.json` paths
+- **Standard compliance**: We're now using the standard Node.js approach without
+  TypeScript-specific workarounds
+- **Reduced maintenance**: One less configuration to keep in sync
+- **Better tooling support**: TypeScript now natively understands the
+  `"imports"` field, providing better IDE support
+
+This supersedes [031-imports](./031-imports.md) as the current approach for
+handling imports in the Epic Stack.
