+# Feedback Form — Design Document
+
+> **Date:** 2026-02-18
+> **Revised:** 2026-02-18 — added DB persistence, feedback type helper text, confirmation email, future TODO notes
+
+## Overview
+
+A feedback form page where logged-in users can submit bug reports, feature requests, and general feedback. Submissions are persisted to a `feedback` database table and emailed to a configurable address via the existing Resend infrastructure. A confirmation email is sent back to the submitter.
+
+## Feedback Types
+
+| Type | Helper Text |
+|------|-------------|
+| Bug Report | Something is broken or not working as expected |
+| Feature Request | An idea for something new you'd like to see |
+| Usability Issue | Something works but is confusing or hard to use |
+| Documentation | Feedback on help docs, tooltips, or in-app guidance |
+| General Feedback | Anything else — thoughts, impressions, suggestions |
+
+## Email Format
+
+### Admin Notification Email
+
+**Subject:**
+```
+[ResolutionFlow Feedback] Bug Report — 2026-02-18 — ACC-7X3K
+```
+
+Where `ACC-7X3K` is the user's account display code.
+
+**Body:**
+```
+Feedback Type: Bug Report
+Submitted By: engineer@example.com
+Account: Contoso IT Services (ACC-7X3K)
+Date: February 18, 2026
+
+---
+
+User's written feedback text goes here...
+```
+
+Reply-to is set to the submitter's email for direct replies.
+
+### Confirmation Email (to submitter)
+
+**Subject:** `Thanks for your feedback — ResolutionFlow`
+
+**Body:** Brief thank you, echoes back the feedback type and a preview of their message (first ~100 chars). Dark-themed HTML matching existing email templates.
+
+Fire-and-forget: if this email fails, it's logged but doesn't affect the user's submission response.
+
+## Database
+
+### `feedback` table
+
+| Column | Type | Notes |
+|--------|------|-------|
+| `id` | UUID | PK |
+| `account_id` | UUID | FK to `accounts`, nullable, SET NULL on delete |
+| `user_id` | UUID | FK to `users`, SET NULL on delete |
+| `email` | String(255) | The reply-to email submitted |
+| `feedback_type` | String(50) | Enum value |
+| `message` | Text | Full feedback text |
+| `created_at` | DateTime(tz) | Timestamp |
+
+Indexes on `account_id`, `user_id`, `created_at`.
+
+No admin view or API read endpoints — queryable directly in the DB when needed.
+
+**Important:** DB write happens *before* email sending. Email failure does NOT prevent the feedback from being saved.
+
+## Frontend
+
+### Page
+
+`FeedbackPage.tsx` — form page inside the app shell.
+
+### Access Points
+
+- Sidebar nav item (icon + "Feedback" label) — visible to all roles
+- Link card on `AccountSettingsPage`
+
+### Route
+
+`/feedback` — top-level app shell route (not nested under `/account`).
+
+### Form Fields
+
+| Field | Details |
+|-------|---------|
+| Email | Auto-filled from logged-in user, editable |
+| Feedback Type | Custom dropdown with description text per option |
+| Message | Textarea, required, min 10 chars |
+| Submit | `bg-gradient-brand`, disabled while submitting |
+
+### UX Flow
+
+1. Form loads with email pre-filled
+2. User opens feedback type dropdown — sees label + helper description for each option
+3. User selects type, writes message, submits
+4. Button shows loading state during submission
+5. On success: success message with confirmation email note, form resets
+6. On error: inline error, form stays populated for retry
+
+### Styling
+
+Standard page layout — `container mx-auto`, `bg-card border border-border rounded-xl` form card, `max-w-2xl` width.
+
+### API Client
+
+`feedbackApi.submit()` in a new `api/feedback.ts` module.
+
+## Backend
+
+### Endpoint
+
+`POST /feedback` in `endpoints/feedback.py`
+
+### Schema
+
+`FeedbackSubmission` in `schemas/feedback.py`:
+- `email: EmailStr` — validated as email
+- `feedback_type: FeedbackType` — enum-validated against the 5 types
+- `message: str` — min 10 chars, max 5000 chars
+
+### Auth
+
+Requires `get_current_active_user`. Account display code pulled from user's account relationship server-side.
+
+### Config
+
+`FEEDBACK_EMAIL: Optional[str] = None` in `config.py`. Endpoint returns 503 if not configured.
+
+### Email Service
+
+Two new static methods on `EmailService`:
+- `send_feedback_email()` — admin notification with reply-to
+- `send_feedback_confirmation_email()` — thank-you to submitter (fire-and-forget)
+
+Both use existing Resend client and dark-themed HTML matching existing email templates.
+
+### Rate Limiting
+
+One submission per minute per user.
+
+## Future Consideration
+
+**Post-session contextual feedback prompt** — do NOT build now. TODO comments in `FeedbackPage.tsx` and `endpoints/feedback.py` serve as breadcrumbs. Concept: after completing a troubleshooting session, show a subtle inline prompt that opens a lightweight version of the feedback form pre-tagged with tree/session context. The feedback infrastructure (DB table, email service, API endpoint) built here should be directly reusable.
+
+## Not Included (YAGNI)
+
+- No admin view for feedback
+- No file attachments
+- No public (unauthenticated) access
