+# Flow-to-Library Step Sync Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** When a flow is published, extract its steps (procedure_steps from procedural/maintenance flows; action/solution nodes from troubleshooting flows) and upsert them into the `step_library` table, keeping them in sync on subsequent publishes, and showing a "From Flow" read-only indicator in the library browser.
+
+**Architecture:** New migration adds 4 columns to `step_library` + a unique constraint on `(source_tree_id, source_node_id)`. A new `backend/app/core/step_sync.py` module handles all extraction and upsert logic. The `update_tree` endpoint calls `sync_steps_from_tree()` after a successful publish. Frontend adds `is_flow_synced` + `source_tree_name` to the Step type, a read-only lock in `StepCard`, and a "Library Visibility" select in `StepEditor`.
+
+**Tech Stack:** Python FastAPI, SQLAlchemy 2.0 async, PostgreSQL JSONB, Alembic, React 19 + TypeScript + Tailwind CSS.
+
+---
+
+## Codebase Context
+
+- **Publish endpoint:** `backend/app/api/endpoints/trees.py:546` — `update_tree()`. Publish validation at line 587. Version increment at line 639. Step sync should be inserted after line 641 (after version increment, before tag replacement at line 643).
+- **Step library model:** `backend/app/models/step_library.py` — `StepLibrary` table, 20 cols. No `source_tree_id` yet.
+- **Step schemas:** `backend/app/schemas/step_library.py` — `StepContent` (lines 15–19), `StepLibraryResponse` (lines 45–64). No `is_flow_synced` yet.
+- **Frontend Step type:** `frontend/src/types/step.ts:15` — `Step` interface. No `is_flow_synced` yet.
+- **StepCard:** `frontend/src/components/step-library/StepCard.tsx` — ownership check via `isOwn = step.created_by === currentUserId`.
+- **StepEditor More Options:** `frontend/src/components/procedural-editor/StepEditor.tsx:138` — `{showMore &&
}` block inside the More Options section.
+- **Fixtures:** `client`, `test_db`, `test_user`, `auth_headers`, `test_tree`, `test_admin`, `admin_auth_headers` from `backend/tests/conftest.py`.
+- **Next migration:** base off `e65b9f8fd458_add_feedback_table.py`.
+- **Test runner:** `cd backend && backend/venv/bin/python -m pytest tests/test_step_sync.py -v --override-ini="addopts="`
+
+---
+
+### Task 1: Database migration — add sync columns to `step_library`
+
+**Files:**
+- Create: `backend/alembic/versions/030_add_step_library_sync_fields.py`
+
+**Step 1: Create the migration file manually (do NOT use autogenerate)**
+
+```bash
+cd /home/michaelchihlas/dev/patherly/backend
+alembic revision -m "add_step_library_sync_fields"
+```
+
+This creates a new file in `backend/alembic/versions/`. Open it and replace the `upgrade()` and `downgrade()` bodies with:
+
+```python
+def upgrade() -> None:
+ op.add_column('step_library', sa.Column('source_tree_id', sa.UUID(), nullable=True))
+ op.add_column('step_library', sa.Column('source_node_id', sa.String(255), nullable=True))
+ op.add_column('step_library', sa.Column('is_flow_synced', sa.Boolean(), nullable=False, server_default='false'))
+ op.add_column('step_library', sa.Column('last_synced_at', sa.DateTime(timezone=True), nullable=True))
+ op.create_foreign_key(
+ 'fk_step_library_source_tree',
+ 'step_library', 'trees',
+ ['source_tree_id'], ['id'],
+ ondelete='SET NULL'
+ )
+ op.create_unique_constraint(
+ 'uq_step_library_source_node',
+ 'step_library',
+ ['source_tree_id', 'source_node_id']
+ )
+ op.create_index('ix_step_library_source_tree_id', 'step_library', ['source_tree_id'])
+
+def downgrade() -> None:
+ op.drop_index('ix_step_library_source_tree_id', 'step_library')
+ op.drop_constraint('uq_step_library_source_node', 'step_library', type_='unique')
+ op.drop_constraint('fk_step_library_source_tree', 'step_library', type_='foreignkey')
+ op.drop_column('step_library', 'last_synced_at')
+ op.drop_column('step_library', 'is_flow_synced')
+ op.drop_column('step_library', 'source_node_id')
+ op.drop_column('step_library', 'source_tree_id')
+```
+
+**Step 2: Run the migration**
+
+```bash
+cd /home/michaelchihlas/dev/patherly/backend
+alembic upgrade head
+```
+
+Expected: `Running upgrade ... -> , add_step_library_sync_fields`
+
+**Step 3: Verify the columns exist**
+
+```bash
+docker exec -it patherly_postgres psql -U postgres -d patherly -c "\d step_library" | grep -E "source_|is_flow|last_sync"
+```
+
+Expected: 4 new columns listed.
+
+**Step 4: Commit**
+
+```bash
+cd /home/michaelchihlas/dev/patherly
+git add backend/alembic/versions/
+git commit -m "feat: add sync tracking columns to step_library
+
+Co-Authored-By: Claude Sonnet 4.6 "
+```
+
+---
+
+### Task 2: Update `StepLibrary` model with new columns
+
+**Files:**
+- Modify: `backend/app/models/step_library.py`
+
+**Step 1: Read the file to find the exact insertion point**
+
+Read `backend/app/models/step_library.py` — find the `is_active` column (last column before relationships). Add the 4 new columns after `is_active`:
+
+```python
+# Sync tracking (flow-sourced steps)
+source_tree_id: Mapped[Optional[uuid_pkg.UUID]] = mapped_column(
+ UUID(as_uuid=True),
+ ForeignKey('trees.id', ondelete='SET NULL'),
+ nullable=True,
+ index=True
+)
+source_node_id: Mapped[Optional[str]] = mapped_column(String(255), nullable=True)
+is_flow_synced: Mapped[bool] = mapped_column(Boolean, nullable=False, default=False)
+last_synced_at: Mapped[Optional[datetime]] = mapped_column(DateTime(timezone=True), nullable=True)
+```
+
+**Step 2: Add the `source_tree` relationship**
+
+In the relationships section of `StepLibrary`, add after the existing `account` relationship:
+
+```python
+source_tree: Mapped[Optional["Tree"]] = relationship(
+ "Tree",
+ foreign_keys=[source_tree_id],
+ lazy="select"
+)
+```
+
+**Step 3: Verify imports**
+
+The file already imports `Optional`, `UUID`, `Boolean`, `String`, `DateTime`, `ForeignKey`, `relationship`. Confirm `mapped_column` and `Mapped` are imported. No new imports should be needed.
+
+**Step 4: Run the backend to check for import errors**
+
+```bash
+cd /home/michaelchihlas/dev/patherly/backend
+backend/venv/bin/python -c "from app.models.step_library import StepLibrary; print('OK')"
+```
+
+Expected: `OK`
+
+**Step 5: Commit**
+
+```bash
+cd /home/michaelchihlas/dev/patherly
+git add backend/app/models/step_library.py
+git commit -m "feat: add sync columns and source_tree relationship to StepLibrary model
+
+Co-Authored-By: Claude Sonnet 4.6 "
+```
+
+---
+
+### Task 3: Update schemas and add `group_label` to `StepContent`
+
+**Files:**
+- Modify: `backend/app/schemas/step_library.py`
+
+**Step 1: Add `group_label` to `StepContent`**
+
+Find `StepContent` (lines 15–19) and add `group_label`:
+
+```python
+class StepContent(BaseModel):
+ instructions: str = Field(..., min_length=1)
+ help_text: Optional[str] = None
+ commands: Optional[list[StepCommand]] = None
+ group_label: Optional[str] = None # Section header this step belongs to (for flow-synced steps)
+```
+
+**Step 2: Add `is_flow_synced` and `source_tree_name` to `StepLibraryResponse`**
+
+Find `StepLibraryResponse` (lines 45–64) and add two fields at the end:
+
+```python
+ is_flow_synced: bool = False
+ source_tree_name: Optional[str] = None
+```
+
+**Step 3: Verify import — `Optional` is already imported from typing**
+
+Read the top of the file to confirm. No new imports needed.
+
+**Step 4: Verify Python import**
+
+```bash
+cd /home/michaelchihlas/dev/patherly/backend
+backend/venv/bin/python -c "from app.schemas.step_library import StepLibraryResponse, StepContent; print('OK')"
+```
+
+Expected: `OK`
+
+**Step 5: Commit**
+
+```bash
+cd /home/michaelchihlas/dev/patherly
+git add backend/app/schemas/step_library.py
+git commit -m "feat: add group_label to StepContent, is_flow_synced to StepLibraryResponse
+
+Co-Authored-By: Claude Sonnet 4.6 "
+```
+
+---
+
+### Task 4: Update step list endpoint to return `is_flow_synced` and `source_tree_name`
+
+**Files:**
+- Modify: `backend/app/api/endpoints/steps.py`
+
+The list endpoint currently returns `StepLibraryResponse` objects built from ORM instances. We need to populate `is_flow_synced` and `source_tree_name`.
+
+**Step 1: Read `backend/app/api/endpoints/steps.py` lines 58–139**
+
+Find where the list query is executed and where response objects are built. Look for the SELECT statement and how it maps to `StepLibraryResponse`.
+
+**Step 2: Add `source_tree_name` to the list query via a join**
+
+The list query will need to LEFT JOIN trees to get the name. Find the existing query and add:
+
+```python
+from app.models.tree import Tree as TreeModel
+
+# In the list query, add a join:
+query = (
+ select(
+ StepLibrary,
+ TreeModel.name.label('source_tree_name')
+ )
+ .outerjoin(TreeModel, StepLibrary.source_tree_id == TreeModel.id)
+ # ... existing filters ...
+)
+```
+
+Then when building the response, pass `source_tree_name` from the joined result.
+
+**Important:** Read the existing query structure carefully before modifying — match whatever pattern (scalar results, row mapping, etc.) is already used.
+
+**Step 3: Also update the single-step GET endpoint** (lines 221–265) to include `source_tree_name` in the same way.
+
+**Step 4: Verify Python import**
+
+```bash
+cd /home/michaelchihlas/dev/patherly/backend
+backend/venv/bin/python -c "from app.api.endpoints.steps import router; print('OK')"
+```
+
+Expected: `OK`
+
+**Step 5: Commit**
+
+```bash
+cd /home/michaelchihlas/dev/patherly
+git add backend/app/api/endpoints/steps.py
+git commit -m "feat: include is_flow_synced and source_tree_name in step list/detail responses
+
+Co-Authored-By: Claude Sonnet 4.6 "
+```

+
+### Task 6: Wire sync into the publish endpoint
+
+**Files:**
+- Modify: `backend/app/api/endpoints/trees.py`
+
+**Step 1: Read lines 583–650 of the file to confirm exact positions**
+
+Confirm line numbers for:
+- The `if "status" in update_data and update_data["status"] == 'published':` block
+- The version increment at `tree.version += 1`
+- The tag replacement block that follows
+
+**Step 2: Add the import at the top of the file**
+
+Near the other core imports (grep for `from app.core`), add:
+
+```python
+from app.core.step_sync import sync_steps_from_tree, deactivate_synced_steps_for_tree
+```
+
+**Step 3: Insert sync call after version increment**
+
+After `tree.version += 1` (line ~641) and before the tag replacement block, add:
+
+```python
+ # Sync steps to library when publishing
+ if update_data.get("status") == 'published' or tree.status == 'published':
+ final_structure = update_data.get("tree_structure", tree.tree_structure)
+ final_type = update_data.get("tree_type", tree.tree_type)
+ await sync_steps_from_tree(
+ db=db,
+ tree_id=tree.id,
+ tree_type=final_type,
+ tree_structure=final_structure,
+ author_id=tree.author_id,
+ account_id=tree.account_id,
+ is_public=update_data.get("is_public", tree.is_public),
+ )
+```
+
+**Step 4: Add deactivation on tree delete**
+
+Find the delete tree endpoint (search for `@router.delete`). After confirming the tree is being deleted, add before commit:
+
+```python
+await deactivate_synced_steps_for_tree(db, tree_id)
+```
+
+**Step 5: Verify Python import**
+
+```bash
+cd /home/michaelchihlas/dev/patherly/backend
+backend/venv/bin/python -c "from app.api.endpoints.trees import router; print('OK')"
+```
+
+Expected: `OK`
+
+**Step 6: Write integration test**
+
+Add to `backend/tests/test_step_sync.py` a new class:
+
+```python
+class TestSyncOnPublish:
+ """Integration tests — sync triggered by publishing a tree."""
+
+ @pytest.mark.asyncio

+ assert synced[0]["title"] == "Updated title"
+```
+
+**Step 7: Run integration tests**
+
+```bash
+cd /home/michaelchihlas/dev/patherly/backend
+backend/venv/bin/python -m pytest tests/test_step_sync.py -v --override-ini="addopts="
+```
+
+Expected: All tests pass.
+
+**Step 8: Commit**

+
+### Task 7: Frontend — update Step types
+
+**Files:**
+- Modify: `frontend/src/types/step.ts`
+
+**Step 1: Read the file to find `Step` and `StepListItem` interfaces**
+
+**Step 2: Add `is_flow_synced` and `source_tree_name` to `Step` (after `is_verified`)**
+
+```typescript
+ is_flow_synced: boolean
+ source_tree_name: string | null
+```
+
+**Step 3: Add same fields to `StepListItem`**
+
+`StepListItem` is the subset used in list views — add there too:
+
+```typescript
+ is_flow_synced: boolean
+ source_tree_name: string | null
+```
+
+**Step 4: Verify build**
+
+```bash
+cd /home/michaelchihlas/dev/patherly/frontend && npm run build 2>&1 | tail -10
+```
+
+Expected: Clean build.
+
+**Step 5: Commit**
+
+```bash
+cd /home/michaelchihlas/dev/patherly
+git add frontend/src/types/step.ts
+git commit -m "feat: add is_flow_synced and source_tree_name to Step types
+
+Co-Authored-By: Claude Sonnet 4.6 "
+```
+
+---
+
+### Task 8: Frontend — read-only indicator in `StepCard`
+
+**Files:**
+- Modify: `frontend/src/components/step-library/StepCard.tsx`
+
+**Step 1: Read the full `StepCard.tsx` to understand current structure**
+
+Find where the Edit button is rendered (look for `onEdit` prop usage and the edit button JSX).
+
+**Step 2: Add `Lock` to Lucide imports**
+
+```tsx
+import { ..., Lock } from 'lucide-react'
+```
+
+**Step 3: Replace the edit button condition**
+
+Currently the edit button likely shows when `isOwn` is true. Change it so that for flow-synced steps, the edit button is replaced by a lock icon with a tooltip:
+
+```tsx
+{isOwn && (
+ step.is_flow_synced ? (
+
+
+
+ ) : (
+ onEdit && (
+
+ )
+ )
+)}
+```
+
+**Step 4: Add "From Flow" badge**
+
+In the badges/chips area of the card (near where `is_featured` or `is_verified` badges are shown), add:
+
+```tsx
+{step.is_flow_synced && (
+
+ From Flow
+
+)}
+```
+
+**Step 5: Verify build**
+
+```bash
+cd /home/michaelchihlas/dev/patherly/frontend && npm run build 2>&1 | tail -10
+```
+
+Expected: Clean build.
+
+**Step 6: Commit**
+
+```bash
+cd /home/michaelchihlas/dev/patherly
+git add frontend/src/components/step-library/StepCard.tsx
+git commit -m "feat: show From Flow badge and lock icon on flow-synced StepCard
+
+Co-Authored-By: Claude Sonnet 4.6 "
+```
+
+---
+
+### Task 9: Frontend — source flow link in `StepDetailModal`
+
+**Files:**
+- Modify: `frontend/src/components/step-library/StepDetailModal.tsx`
+
+**Step 1: Read `StepDetailModal.tsx` to find where step metadata is displayed**
+
+Look for where `author_name`, `usage_count`, `category_name` are rendered in the detail panel.
+
+**Step 2: Add source flow attribution**
+
+In the metadata section, add after the author line:
+
+```tsx
+{step.is_flow_synced && step.source_tree_name && (
+
+
+ Sourced from {step.source_tree_name}
+
+)}
+```
+
+Add `GitBranch` to Lucide imports if not already present.
+
+**Step 3: Verify build**
+
+```bash
+cd /home/michaelchihlas/dev/patherly/frontend && npm run build 2>&1 | tail -10
+```
+
+Expected: Clean build.
+
+**Step 4: Commit**
+
+```bash
+cd /home/michaelchihlas/dev/patherly
+git add frontend/src/components/step-library/StepDetailModal.tsx
+git commit -m "feat: show source flow name in StepDetailModal for synced steps
+
+Co-Authored-By: Claude Sonnet 4.6 "
+```
+
+---
+
+### Task 10: Frontend — Library Visibility select in `StepEditor`
+
+**Files:**
+- Modify: `frontend/src/components/procedural-editor/StepEditor.tsx`
+- Modify: `frontend/src/types/tree.ts` (add `library_visibility` to `ProceduralStep`)
+
+**Step 1: Add `library_visibility` to `ProceduralStep` in `frontend/src/types/tree.ts`**
+
+Find `ProceduralStep` (line ~106) and add after `reference_url?`:
+
+```typescript
+ library_visibility?: 'team' | 'public'
+```
+
+**Step 2: Read `StepEditor.tsx` lines 130–200 to find the More Options block**
+
+The `{showMore &&
}` block starts around line 150. Find the last field inside it.
+
+**Step 3: Add Library Visibility select inside the More Options block**
+
+At the end of the `showMore` content block, before the closing `
`, add:
+
+```tsx
+{/* Library Visibility — only for procedure_step nodes */}
+{step.type === 'procedure_step' && (
+
+
+
+
+ Controls visibility in the step library. Defaults to the flow's own visibility setting.
+
+
+)}
+```
+
+**Step 4: Verify build**
+
+```bash
+cd /home/michaelchihlas/dev/patherly/frontend && npm run build 2>&1 | tail -10
+```
+
+Expected: Clean build.
+
+**Step 5: Commit**
+
+```bash
+cd /home/michaelchihlas/dev/patherly
+git add frontend/src/types/tree.ts frontend/src/components/procedural-editor/StepEditor.tsx
+git commit -m "feat: add Library Visibility select to procedural StepEditor
+
+Co-Authored-By: Claude Sonnet 4.6 "
+```
+

+
+## Manual Verification Checklist
+
+1. **Publish sync:** Create a procedural flow with 2+ steps and a section header → publish → open Step Library → synced steps appear with "From Flow" badge, correct section in group_label
+2. **Republish update:** Edit a step title in a published flow → republish → Step Library shows updated title (not a duplicate)
+3. **Visibility inherit:** Public flow → synced steps have `visibility: 'public'`. Team flow → `visibility: 'team'`
+4. **Per-step override:** Set Library Visibility to "Team only" on a step in a public flow → publish → that step appears as `team` in library while others are `public`
+5. **Read-only in library:** Synced step shows lock icon instead of edit button, tooltip reads "Managed by source flow"
+6. **Source flow name:** Click a synced step → detail panel shows "Sourced from: [Flow Name]"
+7. **Fork works:** Click "Save to Library" on a synced step → creates a personal copy with `is_flow_synced: false`, editable normally
+8. **Troubleshooting sync:** Publish a troubleshooting flow → action and solution nodes appear in library (decision nodes do not)
