plm-skill-packages

PRD §3 #3 product-line carve — Wave 6.5 Conv A.

Hosts the 5-agent PLM PDF→BPMN chain + CSV→BPMN generator + BPMN format controller + build registry + 5-agent orchestrator, plus skill manifests (YAML + filesystem) and the 4-state lifecycle FSM aligned verbatim with PRD §8.11.3.

Lifecycle FSM (Decision #167 — PRD §8.11.3 verbatim)

draft ──► released ──► deprecated ──► retired
              │              │
              └──────────────┴──► (terminal)

States are strictly forward-flowing (matching PRD §8.11.3 4-state capability lifecycle). No revivals, no skips. The FSM rejects any non-canonical transition.

Manifest store (Decision #168 — YAML + filesystem)

Manifests live under plm_skill_packages/manifests/*.yaml and load at boot via manifests.load_all(), matching the litellm_config/model_list.yaml catalog-as-truth pattern. No SQL, no admin UI in V1.

Re-export shims

Every monolith path that today references the lifted modules is preserved as a re-export shim — from agents.plm_structural_analyst import ... continues to work. Pattern matches Wave 1 W1.4 services/run_task_tracker.py (canonical decommission template).

Transitional dependency note

The lifted PLM agent + process_generator code keeps its existing from services.X / from models.X / from utils.X / from agents.base_agent imports. These resolve at runtime in the backend process via PYTHONPATH; standalone sibling tests configure conftest.py to extend sys.path. Wave 7 Extraction physically separates the repos and refactors inbound deps to ports/Protocols.

Wave 6.5 lineage

• Wave 6.5 Conv A (this) — plm-skill-packages carve.
• Wave 6.5 Conv B — plm-knowledge carve (PRD §3 #6).
• Wave 6.5 Conv C — closure audit + Wave 7 readiness re-author.
