Key addition: Process.current() class method (like Machine.current())
that auto-creates/retrieves the Process record for the current OS process.
Benefits:
- Uses PPID lookup to find parent Process automatically
- Detects process_type from sys.argv
- Cached with validation (like Machine.current())
- Eliminates need for thread-local context management
Simplified Phase 3 (workers) and Phase 4 (CLI) to just call
Process.current() instead of manual Process creation.
Documents 7-phase refactoring to use machine.Process as the core data
model for all subprocess management:
- Phase 1: Add parent FK and process_type to Process model
- Phase 2: Add lifecycle methods (launch, kill, poll, wait)
- Phase 3: Update hook system to create Process records
- Phase 4-5: Track workers/orchestrator/supervisord as Process
- Phase 6: Create root Process on CLI invocation
- Phase 7: Admin UI with tree visualization
Enables full process hierarchy tracking from CLI → binary execution.
