Subject: [PATCH 01/18] auto-claude: subtask-1-1 - Extend Finding with
 explanation, fileAge, storageCategory

Add AtlasStorageCategory enum with fine-grained categories (systemCache,
appCache, developerArtifact, browserData, logFile, downloadArtifact,
mailAttachment, oldBackup). Add FileAgeInfo struct for file age metadata.
Add FindingAggregate struct for risk-level summary aggregation. Extend
Finding struct with optional explanation, fileAge, and storageCategory fields.

Subject: [PATCH 03/18] auto-claude: subtask-1-2 - Create
 AtlasFindingExplanations module with explanation generation logic
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add AtlasFindingExplanations enum with three public API functions:
- explanation(for:category:risk:fileAge:) generates human-readable cleanup explanations
- ageDescriptor(from:) converts FileAgeInfo to descriptors like "not used in 6 months"
- localizedExplanation(for:language:) returns explanations in the correct language

Define 24 explanation templates (8 StorageCategory × 3 RiskLevel) with full
zh-Hans and en localization strings including storage category names, file age
descriptors, and combined explanation format strings.

Subject: [PATCH 04/18] auto-claude: subtask-2-1 - Create cmd/analyze/risk.go
 with RiskLevel type, StorageCategory type, and classification functions

Add RiskLevel (safe/review/advanced) and StorageCategory (systemCache, appCache,
developerArtifact, browserData, logFile, downloadArtifact, mailAttachment, oldBackup)
types with riskLevelForPath(), categoryForPath(), and explanationKeyFor() functions.

Subject: [PATCH 05/18] auto-claude: subtask-2-2 - Extend jsonEntry with
 risk/category/timestamp fields

Add RiskLevel, StorageCategory, LastAccessed, CreatedDate, and
ExplanationKey fields to jsonEntry in cmd/analyze/json.go. Update
performScanForJSON() to populate these using existing risk/category
helpers and file system timestamps.

Add CreatedDate field to dirEntry in main.go alongside LastAccess.
Add getCreationTimeFromInfo() helper in scanner.go following the
pattern of getLastAccessTimeFromInfo(). Populate CreatedDate for
symlinks and regular files in scanPathConcurrent().

New JSON fields use omitempty for backward compatibility.

Subject: [PATCH 06/18] auto-claude: subtask-3-1 - Update MoleSmartCleanAdapter
 to parse enriched TSV

Extend MoleSmartCleanAdapter to handle enriched TSV output with optional
risk level, storage category, and file age columns (columns 4-7). Add
storageCategory() classification function for fallback path-based category
assignment. Add enrichFindingsWithFileAge() for file age extraction via
FileManager attributes. Populate explanation, fileAge, and storageCategory
fields on all Finding objects using AtlasFindingExplanations.

Subject: [PATCH 07/18] auto-claude: subtask-3-2 - Add FindingAggregate
 calculation extension

Add Array<Finding> extension with aggregatesByRisk() that computes
FindingAggregate summaries grouped by RiskLevel (safe/review/advanced)
with total bytes and count, and groupedByStorageCategory() that
returns [String: [Finding]] grouped by AtlasStorageCategory.

Subject: [PATCH 08/18] auto-claude: subtask-4-1 - Create AggregateSummaryCard
 with risk-level space breakdown

Add AggregateSummaryCard.swift that displays total reclaimable space
grouped by risk level (safe/review/advanced) with a visual proportion
bar, per-level byte counts, finding counts, and summary text. Follows
AtlasHeroCard pattern for card styling with AtlasTone system. Includes
EN and zh-Hans localization keys for all new strings.

Subject: [PATCH 09/18] auto-claude: subtask-4-2 - Create FindingRowView with
 enhanced finding row component

Introduces FindingRowView.swift in AtlasFeaturesSmartClean, an enhanced row
component for displaying individual scan findings. Shows title, detail, size,
risk badge (AtlasStatusChip with tone), file age indicator (relative date),
storage category tag, and collapsible human-readable explanation text.

Subject: [PATCH 10/18] auto-claude: subtask-4-3 - Update SmartCleanFeatureView
 to integrate all new components

- Add AggregateSummaryCard above risk sections to show total reclaimable space breakdown
- Replace inline AtlasDetailRow finding rows with FindingRowView components
- Add category sub-grouping within each risk section using AtlasSectionDisclosure
- Wire up FindingAggregate calculation via AggregateSummaryCard from findings array
- Preserve existing scan/preview/execute flow unchanged

- Explanation templates per storage category (8 categories)
- File age labels (lastAccessed, created, notUsedIn)
- Aggregate summary labels (title, safelyCleanable, needsReview, requiresAdvanced)
- Category display names (8 storage categories)

Subject: [PATCH 14/18] auto-claude: subtask-6-2 - Add Go tests for risk
 categorization and enriched JSON output

Add comprehensive table-driven tests for:
- riskLevelForPath(): safe/review/advanced risk classification
- categoryForPath(): all 9 storage categories
- explanationKeyFor(): every category+risk combination
- JSON entry serialization with new fields and backward compatibility
- isDeveloperArtifactName() helper

Subject: [PATCH 15/18] auto-claude: subtask-6-3 - Add Swift tests for
 MoleSmartCleanAdapter changes

Add 17 new tests covering enriched TSV parsing, file age extraction,
fallback parsing, storage category classification, and FindingAggregate
computation. All 19 tests pass (2 existing + 17 new).

Subject: [PATCH 18/18] fix: Align Go explanationKeyFor with actual
 localization keys

The Go explanationKeyFor function was generating keys with the format
"smartclean.explanation.<category>.<risk>", but the actual localization
keys in both en.lproj and zh-Hans.lproj use "explanation.<category>.<risk>"
format (matching the Swift-side AtlasFindingExplanations convention).

This fixes the Go JSON API output to produce correct localization keys
that actually exist in the localization files.
