feat: implement research-grade maintainability phases 1,3,4,7
...
Phase 1: Event Sourcing
- Add TaskEvent types (queued, started, completed, failed, etc.)
- Create EventStore with Redis Streams (append-only)
- Support event querying by task ID and time range
Phase 3: Diagnosable Failures
- Enhance TaskExecutionError with Context map, Timestamp, Recoverable flag
- Update container.go to populate error context (image, GPU, duration)
- Add WithContext helper for building error context
- Create cmd/errors CLI for querying task errors
Phase 4: Testable Security
- Add security fields to PodmanConfig (Privileged, Network, ReadOnlyMounts)
- Create ValidateSecurityPolicy() with ErrSecurityViolation
- Add security contract tests (privileged rejection, host network rejection)
- Tests serve as executable security documentation
Phase 7: Reproducible Builds
- Add BuildHash and BuildTime ldflags to Makefile
- Create verify-build target for reproducibility testing
- Add -version and -verify flags to api-server
All tests pass:
- go test ./internal/errtypes/...
- go test ./internal/container/... -run Security
- go test ./internal/queue/...
- go build ./cmd/api-server/...

refactor(cli): reduce code duplication in WebSocket client
...
Add MessageBuilder struct and validation helpers to reduce duplication:
- MessageBuilder: Helper for constructing binary WebSocket messages
- writeOpcode, writeBytes, writeU8/16/32/64
- writeStringU8, writeStringU16 for length-prefixed strings
- Validation helpers: validateApiKeyHash, validateCommitId, validateJobName
- getStream(): Extracted common stream check pattern
Refactored 4 representative send methods to use new helpers:
- sendValidateRequestCommit, sendListJupyterPackages
- sendCancelJob, sendStatusRequest
Consolidated disconnect/close: close() now calls disconnect()
Updated response handlers to use packet.deinit():
- receiveAndHandleResponse
- receiveAndHandleDatasetResponse
Reduces ~100 lines of boilerplate duplication.

refactor(dependency-hygiene): Fix Redis leak, simplify TUI wrapper, clean go.mod
...
Phase 1: Fix Redis Schema Leak
- Create internal/storage/dataset.go with DatasetStore abstraction
- Remove all direct Redis calls from cmd/data_manager/data_sync.go
- data_manager now uses DatasetStore for transfer tracking and metadata
Phase 2: Simplify TUI Services

- Eliminate 60% of wrapper boilerplate (203 -> ~100 lines)
- Keep only TUI-specific methods (EnqueueTask, GetJobStatus, experiment methods)
Phase 5: Clean go.mod Dependencies
- Remove duplicate go-redis/redis/v8 dependency
- Migrate internal/storage/migrate.go to redis/go-redis/v9
- Separate test-only deps (miniredis, testify) into own block
Results:
- Zero direct Redis calls in cmd/
- 60% fewer lines in TUI services
- Cleaner dependency structure

BREAKING CHANGE: Legacy worker files removed, Worker struct simplified
Changes:
1. worker.go - Simplified to 8 fields using composed dependencies:
- runLoop, runner, metrics, health (from new packages)
- Removed: server, queue, running, datasetCache, ctx, cancel, etc.
2. factory.go - Updated NewWorker to use new structure
- Uses lifecycle.NewRunLoop
- Integrates jupyter.Manager properly
3. Removed legacy files:
- execution.go (1,016 lines)
- data_integrity.go (929 lines)
- runloop.go (555 lines)
- jupyter_task.go (144 lines)
- simplified.go (demonstration no longer needed)
4. Fixed references to use new packages:
- hash_selector.go -> integrity.DirOverallSHA256Hex
- snapshot_store.go -> integrity.NormalizeSHA256ChecksumHex
- metrics.go - Removed resource-dependent metrics temporarily
5. Added RecordQueueLatency to metrics.Metrics for lifecycle.MetricsRecorder
Worker struct: 27 fields -> 8 fields (70% reduction)

refactor: Phase 5 - Simplified Worker demonstration
...
Created simplified.go demonstrating target architecture:
internal/worker/simplified.go (109 lines)
- SimplifiedWorker struct with 6 fields vs original 27 fields
- Uses composed dependencies from previous phases:
- lifecycle.RunLoop for task lifecycle management
- executor.JobRunner for job execution
- lifecycle.HealthMonitor for health tracking
- lifecycle.MetricsRecorder for metrics
Key improvements demonstrated:
- Dependency injection via SimplifiedWorkerConfig
- Clear separation of concerns
- No direct resource access (queue, metrics, etc.)
- Each component implements a defined interface
- Easy to test with mock implementations
Note: This is a demonstration of the target architecture.
The original Worker struct remains for backward compatibility.
Migration would happen incrementally in future PRs.

- RunLoopConfig for run loop configuration
- RunLoop type with core orchestration logic
- MetricsRecorder and Logger interfaces for dependencies
- Start(), Stop() methods for loop control
- executeTask() method for task lifecycle management
2. internal/worker/lifecycle/health.go (52 lines)
- HealthMonitor type for health tracking
- RecordHeartbeat(), IsHealthy(), MarkUnhealthy() methods
- Heartbeater interface for heartbeat operations
- HeartbeatLoop() function for background heartbeats
Note: These are interface/type foundations for Phase 5.
The actual Worker struct methods remain in runloop.go until

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

refactor: Phase 1 - Extract worker interfaces
...
Created interfaces package to break tight coupling:
1. internal/worker/interfaces/executor.go (30 lines)
- JobExecutor interface for job execution
- ExecutionEnv struct for execution context
- ExecutionResult struct for results
2. internal/worker/interfaces/tracker.go (20 lines)
- ProgressTracker interface for execution stages
- StageStart, StageComplete, StageFailed methods
- JobComplete for final status
3. internal/worker/interfaces/manifest.go (18 lines)
- ManifestWriter interface for manifest operations
- Upsert method for update/create
- BuildInitial method for creating new manifests
These interfaces will enable:
- Dependency injection in future phases
- Mocking for unit tests
- Clean separation between orchestration and execution

refactor: Phase 4 deferred - Extract GPU utilities and execution helpers
...
Extracted from execution.go to focused packages:
1. internal/worker/gpu.go (60 lines)
- gpuVisibleDevicesString() - GPU device string formatting
- filterExistingDevicePaths() - Device path filtering
- gpuVisibleEnvVarName() - GPU env var selection
- Reuses GPUType constants from gpu_detector.go
2. internal/worker/execution/setup.go (108 lines)
- SetupJobDirectories() - Job directory creation
- CopyDir() - Directory tree copying
- copyFile() - Single file copy helper
3. internal/worker/execution/snapshot.go (52 lines)
- StageSnapshot() - Snapshot staging for jobs
- StageSnapshotFromPath() - Snapshot staging from path
Updated execution.go:
- Removed 64 lines of GPU utilities (now in gpu.go)
- Reduced from 1,082 to ~1,018 lines
- Still contains main execution flow (runJob, executeJob, etc.)

refactor: Migrate all test imports from api to api/ws package
...
Updated 6 test files to use proper api/ws package imports:
1. tests/e2e/websocket_e2e_test.go
- api.NewWSHandler → ws.NewHandler
2. tests/e2e/wss_reverse_proxy_e2e_test.go
- api.NewWSHandler → ws.NewHandler
3. tests/integration/ws_handler_integration_test.go
- api.NewWSHandler → wspkg.NewHandler
- api.Opcode* → wspkg.Opcode*
4. tests/integration/websocket_queue_integration_test.go
- api.NewWSHandler → wspkg.NewHandler
- api.Opcode* → wspkg.Opcode*
5. tests/unit/api/ws_test.go
- api.NewWSHandler → wspkg.NewHandler
- api.Opcode* → wspkg.Opcode*
6. tests/unit/api/ws_jobs_args_test.go
- api.Opcode* → wspkg.Opcode*
Removed api/ws_compat.go shim as all tests now use proper imports.

fix: Add proper WebSocket compatibility shim for test imports
...
Updated api/ws_compat.go to properly delegate to api/ws package:
- NewWSHandler returns http.Handler interface (not interface{})
- All Opcode* constants re-exported from ws package
- Maintains backward compatibility for existing tests
This allows gradual migration of tests to use api/ws directly without
breaking the build. Tests can be updated incrementally.
