+# Serato Doctor
+
+Serato Doctor is a read-only-first toolkit for inspecting and eventually repairing
+DJ libraries. Serato is the first supported engine.
+
+## Analyze a Library
+
+```shell
+serato-doctor analyze \
+  --serato ~/Music/_Serato_ \
+  --music ~/Music/Jukebox
+```
+
+Analysis prints a transparent reference-integrity score plus broken references,
+duplicate filenames, unused tracks, and suggested filename matches. It does not
+modify the library or create report files.
+
+If crates contain an older library root, supply it explicitly:
+
+```shell
+serato-doctor analyze --reference-root /Users/old-user/OneDrive/Jukebox
+```
+
+## Generate Detailed Reports
+
+Running without a command preserves the original scanner behavior and writes CSV
+and text reports:
+
+```shell
+serato-doctor --serato ~/Music/_Serato_ --music ~/Music/Jukebox
+```
+
+Use `--verbose` for progress on standard error or `--log-file PATH` for an
+aggregate diagnostic log.
+
+Serato Doctor never repairs files without an explicit future repair workflow,
+preview, backup, and rollback path.

+# Analyze Command
+
+## Problem
+
+The health and matching engines are only Python APIs. Users need one safe command
+that summarizes library integrity without first interpreting CSV files.
+
+## Architecture
+
+`serato-doctor analyze` reuses the existing configured crate parser and filesystem
+scanner, then prints the immutable health report. The original no-command mode is
+retained as the report-producing scan workflow.
+
+Analyze mode does not create CSV or text reports. Both modes remain read-only with
+respect to Serato crates, databases, and music files.
+
+## Edge Cases
+
+- A library with no references displays `Not assessed` rather than a false score.
+- Historical roots continue to work through repeatable `--reference-root` flags.
+- Normal output remains separate from optional diagnostic logging.
+- Existing scripts that invoke the CLI without a subcommand remain compatible.
+
+## Verification
+
+Tests prove the legacy five-line output and reports remain unchanged, while analyze
+prints health metrics and does not create output files.
