+# Export Improvements Phase B — Design
+
+> **Date:** 2026-02-13
+> **Depends on:** Phase A (complete on `feat/export-phase-a`)
+> **Scope:** B1 (Summary Block), B2 (Custom Step Markers), B3 (Detail Levels), B4 (Editable Preview)
+
+---
+
+## Decisions Made
+
+| Question | Decision |
+|----------|----------|
+| B1 summary form vs single editable preview | Single editable preview (B4). No separate structured form for summary fields. |
+| Detail levels | standard/full only. Dropped "summary" level — primary users are engineers, not dispatchers. |
+| Mid-session editable preview | No. TreeNavigationPage keeps quick one-click copy. Editable preview is SessionDetailPage only. |
+
+---
+
+## 1. Schema Changes
+
+Add to `SessionExport` (backend + frontend):
+
+```python
+include_summary: bool = False
+detail_level: Literal["standard", "full"] = "standard"
+```
+
+No database migration needed — these are export-time options only.
+
+---
+
+## 2. Custom Step Differentiation (B2)
+
+Detect custom steps by checking `node_id.startswith("custom-")` in each decision dict.
+
+**Markdown:**
+```markdown
+### Step 5: [CUSTOM] Check Additional Event Logs
+*Custom step added by engineer*
+```
+
+**Text:**
+```
+5. [CUSTOM] Check Additional Event Logs
+```
+
+**HTML:**
+```html
+<span style="background: #7c3aed; color: white; padding: 2px 6px; border-radius: 3px; font-size: 0.75em; margin-right: 6px;">CUSTOM</span>
+```
+
+**PSA:**
+```
+5. [CUSTOM] Check Additional Event Logs -> ...
+```
+
+Pure backend change — all 4 generators in `export_service.py`.
+
+---
+
+## 3. Summary Block (B1)
+
+When `include_summary=True`, insert a Summary section after metadata, before Evidence/Steps.
+
+Auto-populated fields:
+
+| Field | Source |
+|-------|--------|
+| Issue | Tree name + description |
+| Impact | `[Edit in preview]` placeholder |
+| Status | "Resolved" if completed, else "In Progress — paused at step N" |
+| Resolution | `outcome_notes` if available |
+| Next Steps | `next_steps` if available |
+
+Blank/placeholder fields are editable in the preview modal (B4). Format varies by generator (markdown table, text key-value, HTML styled table, PSA `--- SUMMARY ---` section).
+
+The summary block is opt-in (`include_summary=False` default), independent of detail level.
+
+---
+
+## 4. Detail Levels (B3)
+
+Two levels:
+
+- **standard** (default): Current behavior, except command outputs >5 lines are truncated with `*(full output omitted — N lines)*`
+- **full**: No truncation. All command outputs, scratchpad, notes rendered completely.
+
+Implementation: Helper function `_truncate_command_output(output, max_lines=5)` used in all 4 generators when `detail_level="standard"`.
+
+Frontend: Dropdown on SessionDetailPage export controls — "Standard" / "Full Detail".
+
+---
+
+## 5. Editable Preview (B4)
+
+Modify `ExportPreviewModal`:
+
+- Replace read-only `<pre>` with editable `<textarea>`
+- Local state `editedContent` initialized from `content` prop
+- "Copy" copies `editedContent`
+- "Download" downloads `editedContent`
+- "Reset" button restores original content
+- "Include Summary" checkbox re-fetches export with `include_summary=true`
+- Edits are NOT saved back to the session
+
+Only applies to SessionDetailPage. TreeNavigationPage keeps instant "Copy for Ticket" behavior.
+
+---
+
+## Files Affected
+
+**Backend:**
+- `backend/app/schemas/session.py` — Add `include_summary`, `detail_level` to `SessionExport`
+- `backend/app/services/export_service.py` — All 4 generators: custom step markers, summary block, command output truncation
+
+**Frontend:**
+- `frontend/src/types/session.ts` — Add `include_summary`, `detail_level` to `SessionExport`
+- `frontend/src/components/session/ExportPreviewModal.tsx` — Editable textarea, reset, summary toggle
+- `frontend/src/pages/SessionDetailPage.tsx` — Detail level dropdown, pass new options to export calls
+
+**No migration needed.**

+# Export Improvements Phase B — Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add summary block, custom step markers, detail levels (standard/full), and editable preview modal to the export system.
+
+**Architecture:** Backend changes to all 4 export generators (markdown, text, HTML, PSA) + schema additions. Frontend changes to ExportPreviewModal (editable textarea) and SessionDetailPage (detail level dropdown, summary toggle). No migration needed.
+
+**Tech Stack:** Python FastAPI, Pydantic v2, React 19, TypeScript, Tailwind CSS
+
+**Prerequisites:** Phase A frontend must be merged first (branch `feat/export-phase-a`). Task 7 depends on `maxStepIndex` state and `handleCopyForTicket` from Phase A.
+
+---
+
+## Task 1: Add Phase B Fields to Backend Schema
+
+**Files:**
+- Modify: `backend/app/schemas/session.py:84-91`
+
+**Step 1: Add `include_summary` and `detail_level` to `SessionExport`**
+
+```python
+class SessionExport(BaseModel):
+    format: str = Field(default="markdown", pattern="^(text|markdown|html|psa)$")
+    include_timestamps: bool = True
+    include_tree_info: bool = True
+    # Phase A
+    include_outcome_notes: bool = True
+    include_next_steps: bool = True
+    max_step_index: Optional[int] = Field(None, ge=1, description="1-based inclusive step cutoff")
+    # Phase B
+    include_summary: bool = False
+    detail_level: Literal["standard", "full"] = "standard"
+```
+
+Note: `Literal` is already imported at line 2.
+
+**Step 2: Run tests to verify no regressions**
+
+Run: `cd /c/Dev/Projects/patherly/backend && python -m pytest tests/test_psa_export.py tests/test_export_security.py -v`
+Expected: All existing export tests pass (new fields have defaults, so backward-compatible).
+
+**Step 3: Commit**
+
+```bash
+git add backend/app/schemas/session.py
+git commit -m "feat: add include_summary and detail_level to SessionExport schema"
+```
+
+---
+
+## Task 2: Add Frontend Types for Phase B
+
+**Files:**
+- Modify: `frontend/src/types/session.ts:79-86`
+
+**Step 1: Add `include_summary` and `detail_level` to `SessionExport` interface**
+
+```typescript
+export interface SessionExport {
+  format: 'text' | 'markdown' | 'html' | 'psa'
+  include_timestamps?: boolean
+  include_tree_info?: boolean
+  include_outcome_notes?: boolean
+  include_next_steps?: boolean
+  max_step_index?: number
+  include_summary?: boolean
+  detail_level?: 'standard' | 'full'
+}
+```
+
+**Step 2: Build to verify**
+
+Run: `cd /c/Dev/Projects/patherly/frontend && npx tsc --noEmit`
+Expected: No type errors.
+
+**Step 3: Commit**
+
+```bash
+git add frontend/src/types/session.ts
+git commit -m "feat(frontend): add include_summary and detail_level to SessionExport type"
+```
+
+---
+
+## Task 3: Custom Step Markers (B2) in All 4 Generators
+
+**Files:**
+- Modify: `backend/app/services/export_service.py`
+
+This is a pure backend change. Detect custom steps by `node_id.startswith("custom-")` and prefix the step title with `[CUSTOM]`.
+
+**Step 1: Update `generate_markdown_export`** (line 163)
+
+Change:
+```python
+        lines.append(f"### Step {i}: {question}")
+```
+To:
+```python
+        is_custom = decision.get("node_id", "").startswith("custom-")
+        prefix = "[CUSTOM] " if is_custom else ""
+        lines.append(f"### Step {i}: {prefix}{question}")
+        if is_custom:
+            lines.append("*Custom step added by engineer*")
+```
+
+**Step 2: Update `generate_text_export`** (line 250)
+
+Change:
+```python
+        lines.append(f"\n{i}. {question}")
+```
+To:
+```python
+        is_custom = decision.get("node_id", "").startswith("custom-")
+        prefix = "[CUSTOM] " if is_custom else ""
+        lines.append(f"\n{i}. {prefix}{question}")
+```
+
+**Step 3: Update `generate_html_export`** (line 342)
+
+Change:
+```python
+        html_parts.append(f'<h3>Step {i}: {question}</h3>')
+```
+To:
+```python
+        is_custom = decision.get("node_id", "").startswith("custom-")
+        custom_badge = '<span style="background: #7c3aed; color: white; padding: 2px 6px; border-radius: 3px; font-size: 0.75em; margin-right: 6px;">CUSTOM</span>' if is_custom else ''
+        html_parts.append(f'<h3>{custom_badge}Step {i}: {question}</h3>')
+```
+
+**Step 4: Update `generate_psa_export`** (line 413)
+
+Change:
+```python
+            line = f"{i}. {question}"
+```
+To:
+```python
+            is_custom = decision.get("node_id", "").startswith("custom-")
+            prefix = "[CUSTOM] " if is_custom else ""
+            line = f"{i}. {prefix}{question}"
+```
+
+**Step 5: Run tests**
+
+Run: `cd /c/Dev/Projects/patherly/backend && python -m pytest tests/test_psa_export.py tests/test_export_security.py -v`
+Expected: All pass. (Existing tests don't have custom steps, so markers won't appear — no regressions.)
+
+**Step 6: Commit**
+
+```bash
+git add backend/app/services/export_service.py
+git commit -m "feat: add [CUSTOM] markers to custom steps in all 4 export generators"
+```
+
+---
+
+## Task 4: Command Output Truncation + Detail Levels (B3)
+
+**Files:**
+- Modify: `backend/app/services/export_service.py`
+
+**Step 1: Add format-aware `_truncate_command_output` helper** (after `_get_command_output` at line 91)
+
+The truncation suffix must match the output format — markdown uses `*(...)*`, text/PSA use plain `(...)`, HTML uses `<em>...</em>`.
+
+```python
+def _truncate_command_output(output: str, max_lines: int = 5, fmt: str = "text") -> str:
+    """Truncate command output to max_lines for standard detail level.
+
+    Args:
+        fmt: One of "markdown", "text", "html", "psa" — controls suffix formatting.
+    """
+    lines = output.splitlines()
+    if len(lines) <= max_lines:
+        return output
+    truncated = "\n".join(lines[:max_lines])
+    count = len(lines)
+    if fmt == "markdown":
+        suffix = f"*(full output omitted — {count} lines)*"
+    elif fmt == "html":
+        suffix = f"<em>(full output omitted — {count} lines)</em>"
+    else:  # text, psa
+        suffix = f"(full output omitted — {count} lines)"
+    return f"{truncated}\n{suffix}"
+```
+
+**Step 2: Apply truncation in `generate_markdown_export`** (line 168)
+
+After `if command_output := _get_command_output(decision):` add:
+```python
+            if options.detail_level == "standard":
+                command_output = _truncate_command_output(command_output, fmt="markdown")
+```
+
+**Step 3: Apply truncation in `generate_text_export`** (line 255)
+
+After `if command_output := _get_command_output(decision):` add:
+```python
+            if options.detail_level == "standard":
+                command_output = _truncate_command_output(command_output, fmt="text")
+```
+
+**Step 4: Apply truncation in `generate_html_export`** (line 347)
+
+After `if command_output := _get_command_output(decision):` add:
+```python
+            if options.detail_level == "standard":
+                command_output = _truncate_command_output(command_output, fmt="html")
+```
+
+**Step 5: Apply truncation in `generate_psa_export`** (line 421)
+
+After `if command_output := _get_command_output(decision):` add:
+```python
+            if options.detail_level == "standard":
+                command_output = _truncate_command_output(command_output, fmt="psa")
+```
+
+**Step 6: Run tests**
+
+Run: `cd /c/Dev/Projects/patherly/backend && python -m pytest tests/test_psa_export.py tests/test_export_security.py -v`
+Expected: All pass (default `detail_level="standard"` but existing test command outputs are short).
+
+**Step 7: Commit**
+
+```bash
+git add backend/app/services/export_service.py
+git commit -m "feat: add format-aware command output truncation for standard detail level"
+```
+
+---
+
+## Task 5: Summary Block Generation (B1)
+
+**Files:**
+- Modify: `backend/app/services/export_service.py`
+
+Add summary block generation to all 4 generators. The summary is inserted after metadata, before Evidence/Steps. Only rendered when `options.include_summary is True`.
+
+**Design decision — placeholder policy:** Empty fields (no outcome_notes, no next_steps) are left blank (empty string), NOT filled with `[Edit in preview]`. This avoids placeholder text leaking into copied/exported output. The frontend preview textarea is where users add missing info manually.
+
+**Step 1: Add `_build_summary_fields` helper** (after `_get_outcome_label` at line 113)
+
+```python
+def _build_summary_fields(session: Session) -> dict[str, str]:
+    """Build auto-populated summary fields from session data.
+
+    Empty fields are left blank — users fill them in via the editable preview.
+    """
+    tree_name = session.tree_snapshot.get("name", "Troubleshooting Session")
+    tree_desc = session.tree_snapshot.get("description", "")
+    issue = f"{tree_name}: {tree_desc}" if tree_desc else tree_name
+
+    if session.completed_at:
+        status = "Resolved" if getattr(session, "outcome", None) == "resolved" else \
+                 f"Completed — {_get_outcome_label(session) or 'Unknown'}"
+    else:
+        step_count = len(session.decisions) if session.decisions else 0
+        status = f"In Progress — paused at step {step_count}" if step_count else "In Progress"
+
+    _raw_notes = getattr(session, 'outcome_notes', None)
+    resolution = (_raw_notes if isinstance(_raw_notes, str) else '').strip()
+
+    _raw_next = getattr(session, 'next_steps', None)
+    next_steps = (_raw_next if isinstance(_raw_next, str) else '').strip()
+
+    return {
+        "issue": issue,
+        "impact": "",
+        "status": status,
+        "resolution": resolution,
+        "next_steps": next_steps,
+    }
+```
+
+**Step 2: Add `_escape_markdown_table` helper** (right after `_build_summary_fields`)
+
+Pipe characters and newlines in values break markdown table cells:
+
+```python
+def _escape_markdown_table(value: str) -> str:
+    """Escape value for use in a markdown table cell."""
+    return value.replace("|", "\\|").replace("\n", " ")
+```
+
+**Step 3: Add summary block to `generate_markdown_export`**
+
+Insert after the tree_info block (after line 138, before the scratchpad section):
+
+```python
+    if options.include_summary:
+        summary = _build_summary_fields(session)
+        esc = _escape_markdown_table
+        lines.append("## Summary")
+        lines.append("")
+        lines.append("| Field | Details |")
+        lines.append("|-------|---------|")
+        lines.append(f"| Issue | {esc(summary['issue'])} |")
+        lines.append(f"| Impact | {esc(summary['impact'])} |")
+        lines.append(f"| Status | {esc(summary['status'])} |")
+        lines.append(f"| Resolution | {esc(summary['resolution'])} |")
+        lines.append(f"| Next Steps | {esc(summary['next_steps'])} |")
+        lines.append("")
+        lines.append("---")
+        lines.append("")
+```
+
+**Step 4: Add summary block to `generate_text_export`**
+
+Insert after tree_info block (after line 227, before scratchpad section):
+
+```python
+    if options.include_summary:
+        summary = _build_summary_fields(session)
+        lines.append("SUMMARY")
+        lines.append("-" * 20)
+        lines.append(f"Issue: {summary['issue']}")
+        lines.append(f"Impact: {summary['impact']}")
+        lines.append(f"Status: {summary['status']}")
+        lines.append(f"Resolution: {summary['resolution']}")
+        lines.append(f"Next Steps: {summary['next_steps']}")
+        lines.append("")
+```
+
+**Step 5: Add summary block to `generate_html_export`**
+
+Insert after tree_info `</div>` (after line 321, before scratchpad section):
+
+```python
+    if options.include_summary:
+        summary = _build_summary_fields(session)
+        html_parts.append('<h2>Summary</h2>')
+        html_parts.append('<table style="width: 100%; border-collapse: collapse; margin-bottom: 20px;">')
+        for label, value in [("Issue", summary["issue"]), ("Impact", summary["impact"]),
+                             ("Status", summary["status"]), ("Resolution", summary["resolution"]),
+                             ("Next Steps", summary["next_steps"])]:
+            html_parts.append(f'<tr><td style="padding: 6px 12px; border: 1px solid #ddd; font-weight: bold; width: 120px;">{html.escape(label)}</td>')
+            html_parts.append(f'<td style="padding: 6px 12px; border: 1px solid #ddd;">{html.escape(value)}</td></tr>')
+        html_parts.append('</table>')
+```
+
+**Step 6: Add summary block to `generate_psa_export`**
+
+Insert after `lines.append("")` on line 394 (after the header, before PROBLEM section):
+
+```python
+    if options.include_summary:
+        summary = _build_summary_fields(session)
+        lines.append("--- SUMMARY ---")
+        lines.append(f"Issue: {summary['issue']}")
+        lines.append(f"Impact: {summary['impact']}")
+        lines.append(f"Status: {summary['status']}")
+        lines.append(f"Resolution: {summary['resolution']}")
+        lines.append(f"Next Steps: {summary['next_steps']}")
+        lines.append("")
+```
+
+**Step 7: Run tests**
+
+Run: `cd /c/Dev/Projects/patherly/backend && python -m pytest tests/test_psa_export.py tests/test_export_security.py -v`
+Expected: All pass (summary is opt-in, existing tests don't set `include_summary=True`).
+
+**Step 8: Commit**
+
+```bash
+git add backend/app/services/export_service.py
+git commit -m "feat: add summary block generation to all 4 export generators"
+```
+
+---
+
+## Task 6: Editable Preview Modal (B4)
+
+**Files:**
+- Modify: `frontend/src/components/session/ExportPreviewModal.tsx`
+
+**Design decision — edit preservation on summary toggle:** Toggling "Include Summary" re-fetches from the backend, which resets `editedContent`. This is documented and expected — the toast says "Summary updated" so the user understands. Edits are lightweight (engineers tweak a few words), so the cost of re-typing is low vs. the complexity of merging diffs.
+
+**Step 1: Replace read-only preview with editable textarea and add controls**
+
+Rewrite the component:
+
+```tsx
+import { useState, useEffect } from 'react'
+import { Copy, Download, Check, RotateCcw } from 'lucide-react'
+import { Modal } from '@/components/common/Modal'
+import { cn } from '@/lib/utils'
+
+interface ExportPreviewModalProps {
+  isOpen: boolean
+  onClose: () => void
+  content: string
+  filename: string
+  format: 'markdown' | 'text' | 'html' | 'psa'
+  onDownload: (content: string) => void
+  includeSummary?: boolean
+  onToggleSummary?: (include: boolean) => void
+}
+
+export function ExportPreviewModal({
+  isOpen,
+  onClose,
+  content,
+  filename,
+  format,
+  onDownload,
+  includeSummary = false,
+  onToggleSummary,
+}: ExportPreviewModalProps) {
+  const [copied, setCopied] = useState(false)
+  const [editedContent, setEditedContent] = useState(content)
+
+  // Sync editedContent when content prop changes (new fetch / summary toggle)
+  useEffect(() => {
+    setEditedContent(content)
+  }, [content])
+
+  const handleCopy = async () => {
+    try {
+      await navigator.clipboard.writeText(editedContent)
+      setCopied(true)

+            'flex items-center gap-2 rounded-md bg-white px-3 py-2 text-sm font-medium text-black',
+            'hover:bg-white/90 focus:outline-none focus:ring-2 focus:ring-white/20'

+        </button>
+      </div>
+    </Modal>
+  )
+}
+
+export default ExportPreviewModal
+```
+
+Key changes:
+- `<pre>` → `<textarea>` with `editedContent` local state
+- Copy/Download use `editedContent` instead of `content` prop
+- Reset button appears when content is modified
+- `onDownload` signature changes to `(content: string) => void` to receive edited content
+- New optional `includeSummary` + `onToggleSummary` props for summary checkbox
+- `(edited)` indicator when content has been modified
+- Summary toggle re-fetches content, resetting edits (documented behavior — avoids diff-merge complexity)
+
+**Step 2: Build to verify**
+
+Run: `cd /c/Dev/Projects/patherly/frontend && npx tsc --noEmit`
+
+Fix any type errors from the `onDownload` signature change (see Task 7).
+
+**Step 3: Commit**
+
+```bash
+git add frontend/src/components/session/ExportPreviewModal.tsx
+git commit -m "feat(frontend): convert ExportPreviewModal to editable textarea with reset"
+```
+

+
+## Task 7: Wire Up Phase B Controls in SessionDetailPage
+
+**Files:**
+- Modify: `frontend/src/pages/SessionDetailPage.tsx`
+
+**Step 1: Add state for detail level and include summary** (after line 34)
+
+```typescript
+const [detailLevel, setDetailLevel] = useState<'standard' | 'full'>('standard')
+const [includeSummary, setIncludeSummary] = useState(false)
+```
+
+**Step 2: Update `fetchExportContent` to include Phase B options** (line 92-101)
+
+```typescript
+  const fetchExportContent = async () => {
+    if (!session) return null
+    const options: SessionExport = {
+      format: exportFormat,
+      include_timestamps: true,
+      include_tree_info: true,
+      ...(maxStepIndex !== null && { max_step_index: maxStepIndex }),
+      detail_level: detailLevel,
+      include_summary: includeSummary,
+    }
+    return await sessionsApi.export(session.id, options)
+  }
+```
+
+**Step 3: Update `handleCopyForTicket` to include Phase B options** (line 140-145)
+
+```typescript
+      const options: SessionExport = {
+        format: 'psa',
+        include_timestamps: true,
+        include_tree_info: true,
+        ...(maxStepIndex !== null && { max_step_index: maxStepIndex }),
+        detail_level: detailLevel,
+        include_summary: includeSummary,
+      }
+```
+
+**Step 4: Update `handleDownload` to accept content parameter** (line 159)
+
+Change:
+```typescript
+  const handleDownload = () => {
+    if (!exportContent || !session) return
+    const blob = new Blob([exportContent], { type: 'text/plain' })
+```
+To:
+```typescript
+  const handleDownload = (content: string) => {
+    if (!session) return
+    const blob = new Blob([content], { type: 'text/plain' })
+```
+
+**Step 5: Add `onToggleSummary` handler** with error handling
+
+```typescript
+  const handleToggleSummary = async (include: boolean) => {
+    setIncludeSummary(include)
+    if (!session) return
+    const options: SessionExport = {
+      format: exportFormat,
+      include_timestamps: true,
+      include_tree_info: true,
+      ...(maxStepIndex !== null && { max_step_index: maxStepIndex }),
+      detail_level: detailLevel,
+      include_summary: include,
+    }
+    try {
+      const content = await sessionsApi.export(session.id, options)
+      if (content) {
+        setExportContent(content)
+        toast.success(include ? 'Summary added' : 'Summary removed')
+      }
+    } catch (err) {
+      console.error('Failed to re-fetch export:', err)
+      toast.error('Failed to update export')
+      setIncludeSummary(!include)  // Revert checkbox on failure
+    }
+  }
+```
+
+**Step 6: Add detail level dropdown** to the export controls area (after step cutoff dropdown, before copy button — after line 408)
+
+```tsx
+<select
+  value={detailLevel}
+  onChange={(e) => setDetailLevel(e.target.value as 'standard' | 'full')}
+  aria-label="Detail level"
+  className={cn(
+    'rounded-md border border-white/10 bg-black/50 px-3 py-2 text-sm text-white',
+    'focus:border-white/30 focus:outline-none focus:ring-1 focus:ring-white/20'
+  )}
+>
+  <option value="standard">Standard</option>
+  <option value="full">Full Detail</option>
+</select>
+```
+
+**Step 7: Update ExportPreviewModal props** (line 516-523)
+
+```tsx
+<ExportPreviewModal
+  isOpen={showPreview}
+  onClose={() => setShowPreview(false)}
+  content={exportContent || ''}
+  filename={getFilename()}
+  format={exportFormat}
+  onDownload={handleDownload}
+  includeSummary={includeSummary}
+  onToggleSummary={handleToggleSummary}
+/>
+```
+
+**Step 8: Build to verify**
+
+Run: `cd /c/Dev/Projects/patherly/frontend && npx tsc --noEmit`
+Expected: No type errors.
+
+**Step 9: Commit**
+
+```bash
+git add frontend/src/pages/SessionDetailPage.tsx
+git commit -m "feat(frontend): add detail level dropdown and summary toggle to export controls"
+```
+
+---
+
+## Task 8: Backend Tests for Phase B Features
+
+**Files:**
+- Modify: `backend/tests/test_psa_export.py`
+
+Uses existing `_make_session` helper and `_default_options` from `test_psa_export.py`. Also imports additional generators for cross-format tests.
+
+**Step 1: Add imports** at the top of `test_psa_export.py`
+
+```python

+    generate_psa_export, generate_text_export, generate_markdown_export,
+    generate_html_export, _format_duration,

+
+## Task 9: Final Build Verification
+
+**Step 1: Run full backend tests**
+
+Run: `cd /c/Dev/Projects/patherly/backend && python -m pytest --override-ini="addopts=" -v`
+Expected: All tests pass.
+
+**Step 2: Run frontend build**
+
+Run: `cd /c/Dev/Projects/patherly/frontend && npm run build`
+Expected: Build succeeds with no errors.
+
+**Step 3: Verify git status is clean**
+
+```bash
+git status
+git log --oneline feat/export-phase-a --not main | head -20
+```
+
+---
+
+## Frontend Acceptance Checklist (Manual QA)
+
+1. **Editable preview:** Open Preview, edit text, verify Copy/Download use edited content. Click Reset to restore original.
+2. **Summary toggle:** Check "Include Summary" in preview — export re-fetches with summary block (edits reset, toast confirms). Uncheck removes it.
+3. **Summary toggle error:** Disconnect network, toggle summary — checkbox reverts, error toast shown.
+4. **Detail level:** Select "Full Detail", export a session with long command output — no truncation. Switch to "Standard" — output truncated with format-appropriate marker.
+5. **Custom step markers:** Export a session with custom steps — should show `[CUSTOM]` prefix.
+6. **Summary block content:** Summary should auto-populate Issue from tree name, Status from completion state, Resolution from outcome_notes. Empty fields are blank (no placeholder text).
+7. **No placeholder leak:** Enable summary on a session with no outcome_notes — Resolution field should be blank, not show `[Edit in preview]`.
