Jeremie Fraeys	a1ce267b86	feat: Implement all worker stub methods with real functionality ... - VerifySnapshot: SHA256 verification using integrity package - EnforceTaskProvenance: Strict and best-effort provenance validation - RunJupyterTask: Full Jupyter service lifecycle (start/stop/remove/restore/list_packages) - RunJob: Job execution using executor.JobRunner - PrewarmNextOnce: Prewarming with queue integration All methods now use new architecture components instead of placeholders	2026-02-17 17:37:56 -05:00
Jeremie Fraeys	4c8c9dfe4b	refactor: Export SelectDependencyManifest for API helpers ... - Renamed selectDependencyManifest to SelectDependencyManifest (exported) - Added re-export in worker package for backward compatibility - Updated internal call in container.go to use exported function - API helpers can now access via worker.SelectDependencyManifest Build status: Compiles successfully	2026-02-17 16:45:59 -05:00
Jeremie Fraeys	a7360869f8	refactor: Implement TaskExecutorAdapter and Worker.runningCount() ... - Created executor/TaskExecutorAdapter implementing lifecycle.TaskExecutor - Properly wires LocalExecutor and ContainerExecutor through adapter - Worker.runningCount() now delegates to runLoop.RunningCount() - Added lifecycle.RunLoop.RunningCount() public method - factory.go creates proper executor chain instead of placeholder Build status: Compiles successfully	2026-02-17 16:15:41 -05:00
Jeremie Fraeys	22f3d66f1d	refactor: Phase 2 - Extract executor implementations ... Created executor package with extracted job execution logic: 1. internal/worker/executor/local.go (104 lines) - LocalExecutor implements JobExecutor interface - Execute() method for local bash script execution - generateScript() helper for creating experiment scripts 2. internal/worker/executor/container.go (229 lines) - ContainerExecutor implements JobExecutor interface - Execute() method for podman container execution - EnvironmentPool interface for image caching - Tracking tool provisioning (MLflow, TensorBoard, Wandb) - Volume and cache setup - selectDependencyManifest() helper 3. internal/worker/executor/runner.go (131 lines) - JobRunner orchestrates execution - ExecutionMode enum (Auto, Local, Container) - Run() method with directory setup and executor selection - finalize() for success/failure handling Key design decisions: - Executors depend on interfaces (ManifestWriter, not Worker) - JobRunner composes both executors - No direct Worker dependencies in executor package - SetupJobDirectories reused from execution package Build status: Compiles successfully	2026-02-17 14:14:04 -05:00
