 This changelog is maintained from git history plus the published Gitea release series. Future releases should update this file and publish matching release notes on the release page.
 
+## v0.10.0
+
+Ports and adapters refactor.
+
+- Extract shared manifest types into `internal/manifest/types` leaf package.
+- Extract SQLite adapter into `internal/manifest/sqlite`: Store, Adapter, LogWriter.
+- Extract JSONL adapter into `internal/manifest/jsonl`: Store, Adapter.
+- `modernc.org/sqlite` import isolated to `internal/manifest/sqlite/adapter.go`.
+- Registry pattern: `manifest.Default` provides adapter-backed `ParseFormat`/`Open`/`OpenLogWriter`.
+- Adapter-agnostic `ConvertManifest` in `types/` for JSONL↔SQLite conversion.
+- `MemoryAdapter` for in-memory manifest testing.
+- CLI uses `manifest.Default` registry directly; zero concrete adapter references.
+- SQLite `LogWriter` type assertion moved from central code into `SQLiteAdapter`.
+- `Manifest` interface now includes `Entries()`; `EntryReader` removed.
+- No behavior changes, no new features.
+- 100% statement coverage across all 6 packages.
+
+## v0.9.4
+
+Doctor release.
+
+- Add `doctor` to check Photos access and optional backup health.
+- Add `doctor --out <dir>` to report backup directory, manifest entries, and failure count.
+- Add `doctor --json` for scriptable diagnostics.
+
+## v0.9.3
+
+Cleanup release.
+
+- Add `cleanup --out <dir>` to remove files not referenced by the manifest.
+- Add `cleanup --dry-run` to preview orphaned files before deletion.
+- Preserve manifest/log/failure files, `.photoscli`, and sidecars for manifest-referenced media.
+
+## v0.9.2
+
+Manifest repair release.
+
+- Add `manifest repair --out <dir>` to fill missing manifest size metadata from files on disk.
+- Add `manifest repair --checksum sha256` to fill missing manifest checksums.
+- Add `manifest repair --dry-run` to preview repairs without writing manifest updates.
+
+## v0.9.1
+
+Deep checksum verification release.
+
+- Add `verify --deep` to recompute SHA-256 checksums for manifest entries that have checksum metadata.
+- Report `checksum-mismatch` when disk contents differ from the manifest checksum.
+- Keep normal `verify` unchanged unless `--deep` is selected.
+
 ## v0.9.0
 
 Manifest checksum release.

-# v0.9.0
+# v0.10.0
 
-This release starts the backup-integrity series with manifest checksums.
+Ports and adapters refactor. No user-visible changes.
 
 ## Highlights
 
-- Add opt-in `--checksum sha256` to store SHA-256 checksums in manifests.
-- Support checksums in both JSONL and SQLite manifests.
-- Add SQLite migration support for the new checksum column.
-- Keep checksum collection disabled by default with `--checksum none`.
+- Extract manifest types, registry, and conversion logic into `internal/manifest/types`.
+- Extract SQLite adapter into `internal/manifest/sqlite` with its own store, adapter, and log writer.
+- Extract JSONL adapter into `internal/manifest/jsonl` with its own store and adapter.
+- Isolate `modernc.org/sqlite` import to the SQLite adapter package only.
+- Replace central `Open`/`ParseFormat`/`OpenLogWriter` with adapter-backed registry.
+- Adapter-agnostic manifest conversion via `ConvertManifest`.
+- SQLite log writer selection moved from central code into `SQLiteAdapter`.
+- CLI uses `manifest.Default` registry; no direct references to concrete JSONL or SQLite types.
+- `MemoryAdapter` available for in-memory manifest tests.
+- 100% statement coverage across all 6 packages.
+- No behavior changes.
 
 ## Assets
 
 - `photoscli`: Apple Silicon macOS binary (`darwin/arm64`).
-- `photoscli-0.9.0-macos-arm64.zip`: Apple Silicon binary plus README, USERGUIDE, and CHANGELOG.
+- `photoscli-0.10.0-macos-arm64.zip`: Apple Silicon binary plus README, USERGUIDE, and CHANGELOG.
 - `USERGUIDE.md`: standalone user guide.
 
 Intel Macs are not currently a supported release target.

@@ -830,6 +830,42 @@ Store SHA-256 checksums in the manifest when exporting:
 
 Checksums are opt-in and stored in JSONL or SQLite manifests. The default is `--checksum none`.
 
+Deep-verify checksum-backed manifests:
+
+```bash
+./bin/photoscli verify --out ./PhotosBackup --deep
+```
+
+`--deep` recomputes SHA-256 only for manifest entries that already have checksum metadata.
+
+Repair missing manifest metadata from files already present on disk:
+
+```bash
+./bin/photoscli manifest repair --out ./PhotosBackup --checksum sha256 --dry-run
+./bin/photoscli manifest repair --out ./PhotosBackup --checksum sha256
+```
+
+Repair fills missing size/checksum metadata and skips missing, zero-byte, or unreadable files.
+
+Preview and remove files not referenced by the manifest:
+
+```bash
+./bin/photoscli cleanup --out ./PhotosBackup --dry-run
+./bin/photoscli cleanup --out ./PhotosBackup
+```
+
+Cleanup preserves manifest/log/failure files, `.photoscli`, and sidecars next to manifest-referenced media.
+
+Run read-only diagnostics:
+
+```bash
+./bin/photoscli doctor
+./bin/photoscli doctor --out ./PhotosBackup
+./bin/photoscli doctor --out ./PhotosBackup --json
+```
+
+Doctor checks Photos access and, when `--out` is provided, backup directory status, manifest entries, and failure count.
+
 ## Safe Operating Practices
 
 - Run `--dry-run` before the first large backup.
