TRACK-012: Bulk Import Review Workflow Completion

Related Tracks	TRACK-001 (Bulk Import), TRACK-011 (Quality Scoring)
Implementation Plan	bulk-import-fixes-implementation-plan.md

1. Goal

Complete the review workflow APIs and frontend enhancements to enable batch-scale moderation workflows, quality-tier based filtering, and configurable auto-approval rules.

2. Problem Statement

Current implementation has:

• ✅ Per-import review (individual approve/reject)
• ✅ Batch-level approve-all/reject-all
• ❌ Missing bulk-review API endpoint
• ❌ Missing auto-approve queue API endpoint
• ❌ Hardcoded auto-approval rules (not configurable)
• ❌ No batch filter in review queue (frontend)
• ❌ No quality tier filtering (frontend)

Impact:

• Cannot efficiently review large batches (1,200+ entries)
• Auto-approval cannot use quality tiers
• Reviewers cannot filter by batch or quality tier

3. Implementation Plan

3.1 Backend: Bulk Review API

File: modules/backend/api/src/main/kotlin/com/sangita/grantha/backend/api/routes/ImportRoutes.kt

New Endpoint:

/**
 * POST /v1/admin/imports/bulk-review
 * 
 * Review multiple imports in a single request.
 * 
 * Request body:
 * {
 *   "importIds": ["uuid1", "uuid2", ...],
 *   "action": "APPROVE" | "REJECT",
 *   "overrides": { ... }  // Optional entity overrides
 * }
 */
post("/bulk-review") {
    val request = call.receive<BulkReviewRequest>()
    
    val results = request.importIds.map { importId ->
        try {
            when (request.action) {
                "APPROVE" -> {
                    importService.reviewImport(
                        importId = importId,
                        request = ImportReviewRequest(
                            action = ImportReviewAction.APPROVE,
                            overrides = request.overrides
                        )
                    )
                    BulkReviewResult(importId, "APPROVED", null)
                }
                "REJECT" -> {
                    importService.reviewImport(
                        importId = importId,
                        request = ImportReviewRequest(
                            action = ImportReviewAction.REJECT,
                            reason = request.reason
                        )
                    )
                    BulkReviewResult(importId, "REJECTED", null)
                }
                else -> BulkReviewResult(importId, "ERROR", "Invalid action")
            }
        } catch (e: Exception) {
            BulkReviewResult(importId, "ERROR", e.message)
        }
    }
    
    call.respond(mapOf(
        "total" to results.size,
        "succeeded" to results.count { it.status != "ERROR" },
        "failed" to results.count { it.status == "ERROR" },
        "results" to results
    ))
}

3.2 Backend: Auto-Approve Queue API

File: modules/backend/api/src/main/kotlin/com/sangita/grantha/backend/api/routes/ImportRoutes.kt

New Endpoint:

/**
 * GET /v1/admin/imports/auto-approve-queue
 * 
 * Returns imports that meet auto-approval criteria.
 * 
 * Query parameters:
 * - batchId: Filter by batch (optional)
 * - qualityTier: Filter by quality tier (EXCELLENT, GOOD, FAIR, POOR) (optional)
 * - confidenceMin: Minimum confidence score (0.0-1.0) (optional)
 * - limit: Max results (default: 100)
 * - offset: Pagination offset (default: 0)
 */
get("/auto-approve-queue") {
    val batchId = call.request.queryParameters["batchId"]?.let { Uuid.parse(it) }
    val qualityTier = call.request.queryParameters["qualityTier"]
    val confidenceMin = call.request.queryParameters["confidenceMin"]?.toDoubleOrNull()
    val limit = call.request.queryParameters["limit"]?.toIntOrNull() ?: 100
    val offset = call.request.queryParameters["offset"]?.toIntOrNull() ?: 0
    
    val queue = importService.getAutoApproveQueue(
        batchId = batchId,
        qualityTier = qualityTier,
        confidenceMin = confidenceMin,
        limit = limit,
        offset = offset
    )
    
    call.respond(queue)
}

    batchId: Uuid? = null,
    qualityTier: String? = null,
    confidenceMin: Double? = null,

3.4 Frontend: Batch Filter in Review Queue

File: modules/frontend/sangita-admin-web/src/pages/ReviewQueue.tsx

Changes:

// Add batch filter dropdown
const [selectedBatchId, setSelectedBatchId] = useState<string | null>(null);
const [batches, setBatches] = useState<ImportBatch[]>([]);

useEffect(() => {
    // Load batches for filter dropdown
    api.bulkImport.listBatches({ limit: 100 }).then(setBatches);
}, []);

// Update API call to include batchId filter
const loadImports = async () => {
    const params: any = { status: 'PENDING' };
    if (selectedBatchId) {
        params.batchId = selectedBatchId;
    }
    const data = await api.imports.listImports(params);
    setImports(data);
};

// Add filter UI
<div className="mb-4">
    <label className="block text-sm font-medium mb-2">Filter by Batch:</label>
    <select
        value={selectedBatchId || ''}
        onChange={(e) => setSelectedBatchId(e.target.value || null)}
        className="border rounded px-3 py-2"
    >
        <option value="">All Batches</option>
        {batches.map(batch => (
            <option key={batch.id} value={batch.id}>
                {batch.sourceManifest} ({batch.status})
            </option>
        ))}
    </select>
</div>

3.5 Frontend: Quality Tier Filtering

File: modules/frontend/sangita-admin-web/src/pages/ReviewQueue.tsx

Changes:

const [selectedQualityTier, setSelectedQualityTier] = useState<string | null>(null);

const qualityTiers = ['EXCELLENT', 'GOOD', 'FAIR', 'POOR'];

// Add quality tier filter UI
<div className="mb-4">
    <label className="block text-sm font-medium mb-2">Filter by Quality Tier:</label>
    <select
        value={selectedQualityTier || ''}
        onChange={(e) => setSelectedQualityTier(e.target.value || null)}
        className="border rounded px-3 py-2"
    >
        <option value="">All Tiers</option>

            <option key={tier} value={tier}>{tier}</option>
        ))}
    </select>
</div>

// Update API call
const loadImports = async () => {
    const params: any = { status: 'PENDING' };
    if (selectedBatchId) params.batchId = selectedBatchId;
    if (selectedQualityTier) params.qualityTier = selectedQualityTier;
    const data = await api.imports.listImports(params);
    setImports(data);
};

3.6 Frontend: Auto-Approve Queue View

File: modules/frontend/sangita-admin-web/src/pages/AutoApproveQueue.tsx (new)

Implementation:

export const AutoApproveQueue: React.FC = () => {
    const [imports, setImports] = useState<ImportedKrithi[]>([]);
    const [selectedBatchId, setSelectedBatchId] = useState<string | null>(null);
    
    const loadQueue = async () => {
        const params: any = {};
        if (selectedBatchId) params.batchId = selectedBatchId;
        const data = await api.imports.getAutoApproveQueue(params);
        setImports(data);
    };
    
    const handleBulkApprove = async () => {
        const importIds = imports.map(i => i.id);
        await api.imports.bulkReview({
            importIds,
            action: 'APPROVE'
        });
        await loadQueue();
    };
    
    return (
        <div>
            <h1>Auto-Approve Queue</h1>
            <button onClick={handleBulkApprove}>
                Approve All ({imports.length})
            </button>
            {/* Import list with quality scores */}
        </div>
    );
};
