 # Workflow Implementation Backlog
 
+Execution orchestration, ownership split, and merge order are tracked in [`docs/workflows/WORKERS.md`](/home/hartmut/Documents/Copilot/schaefflerautomat/docs/workflows/WORKERS.md).

 - `E2-T3` Add `GET /api/workflows/node-definitions`.
 - `E2-T4` Provide schema-driven defaults and editor field groups.

 ### Required Node Coverage

 - `E4-T4` Support retry and failure policies. `completed`

+- `E4-T9` Extend runtime, dispatch, and task tests for graph-authoritative still persistence and legacy-safe notify handoff. `completed`
+- `E4-T10` Extend graph-authoritative `output_save` semantics to `export_blend`, including asset persistence and node-result updates without mutating the primary order-line render output. `completed`
+- `E4-T11` Extend graph-authoritative `output_save` semantics to `blender_turntable`, including graph/legacy-safe task argument handling, authoritative persistence, and node-result updates for video outputs. `completed`
 
 ## Epic 5: Editor Parity
 
@@ -87,6 +95,20 @@
 - `E5-T4` Add graph validation in the editor.
 - `E5-T5` Add dry-run and dispatch from the editor.
 - `E5-T6` Add workflow run inspection UI.
+- `E5-T7` Reorganize authoring around family-specific starter graphs and family-safe palettes.
+- Progress: The editor already supports right-click node insertion, searchable family-aware palettes, auto-align, edge deletion, dry-run/dispatch, and run inspection. The current remaining parity slice is authoring polish and validation around the canonical non-legacy still graph, not missing basic editor mechanics.

+## Epic 7: Output-Type Invocation Profiles

+### Tickets
+
+- `E7-T1` Align frontend/backend defaults and allowed values for output-type creation. `completed`
+- `E7-T2` Define explicit workflow family on output types. `completed`
+- `E7-T3` Separate invocation overrides from legacy raw render settings. `completed`
+- `E7-T4` Add artifact-kind contract to output types. `completed`
+- `E7-T5` Validate output-type family/workflow compatibility in backend APIs. `completed`
+- `E7-T6` Redesign admin create/edit flow around workflow invocation instead of legacy renderer flags. `completed`
+- Progress: Output types now persist an explicit workflow family, artifact kind, and invocation override set; backend APIs reject family/artifact mismatches against linked workflows; serializer output exposes a typed invocation profile instead of leaking raw dict payloads.
