+# US01-01 — Inventory and Characterize Donor Code
+
+Epic: [E01](../E01-shared-identity-inventory.md)
+
+As a maintainer, I want a donor ledger and characterization suite for the current CLI
+implementations so proven behavior is reused deliberately instead of rewritten.
+
+## Acceptance criteria
+
+- Relevant functions in both CLI codebases are classified as reuse, extract, refactor,
+  or replace, with rationale and target module.
+- The ledger covers discovery, hashing, imaging, NSFW, vision, EXIF, database, UI,
+  configuration, logging, cancellation, and error behavior.
+- Representative current outputs are captured against stable fixture IDs.
+- No legacy file is moved or archived in this story.
+
+## Automated tests
+
+- Characterization tests run against current donor entry points and core functions.
+- A ledger-lint test rejects missing source references, target locations, or test IDs.
