+# paracas-daemon
+
+Background job management for the paracas tick data downloader.
+
+## Features
+
+- Job tracking with unique identifiers
+- Persistent state storage
+- Detached daemon process spawning
+- Thread-safe progress tracking
+
+## Types
+
+- `JobId` - Unique identifier for download jobs
+- `JobStatus` - Current status of a job (pending, running, completed, failed)
+- `InstrumentTask` - Download task for a single instrument
+- `DownloadJob` - Complete download job with multiple tasks
+- `StateManager` - Persistent state storage and retrieval
+- `DaemonSpawner` - Spawns detached daemon processes
+- `DaemonProgress` - Thread-safe progress tracking
+
+## Usage
+
+```rust,ignore
+use paracas_daemon::{StateManager, DownloadJob, JobId, JobStatus};
+
+// Create a state manager
+let manager = StateManager::new()?;
+
+// Create a new job
+let job = DownloadJob::new(tasks);
+manager.save_job(&job)?;
+
+// Retrieve job status
+if let Some(job) = manager.get_job(&job.id)? {
+    println!("Job status: {:?}", job.status());
+}

+# paracas-estimate
+
+Download size and time estimation for the paracas tick data downloader.
+
+## Features
+
+- Historical size estimates per instrument category
+- Download time estimation based on data volume
+- Confidence levels for estimates
+
+## Types
+
+- `EstimateDatabase` - Database of historical size estimates per category
+- `CategoryEstimate` - Size estimates for a single category
+- `Estimator` - Computes download estimates for instruments and date ranges
+- `DownloadEstimate` - Estimated download metrics
+- `EstimateConfidence` - Confidence level of the estimate
+
+## Usage
+
+```rust,ignore
+use paracas_estimate::{Estimator, EstimateDatabase};
+use paracas_types::{Category, DateRange};
+
+// Create an estimator with the default database
+let db = EstimateDatabase::default();
+let estimator = Estimator::new(&db);
+
+// Estimate download for a date range
+let range = DateRange::new(start, end)?;
+let estimate = estimator.estimate(Category::Forex, &range);
+
+println!("Estimated size: {} bytes", estimate.size_bytes);
+println!("Confidence: {:?}", estimate.confidence);
