# Changelog, Roadmap & Feedback Design Spec

**Date:** 2026-03-30
**Status:** Approved

---

## Overview

Add a public `/changelog` page with three tabs (What's New, What's Next, Give Feedback), auth-gated upvoting on roadmap items, a shared feedback form available as a standalone page and a modal triggered from the nav/footer, and an admin view for reviewing submissions.

---

## Goals

- Publicly share release notes (changelog) and upcoming work (roadmap)
- Let authenticated users upvote roadmap items to signal priority
- Collect structured user feedback (bug / feature / general) with optional email
- Store feedback in Spring Boot DB, reviewable in the admin panel
- Add "Send Feedback" entry point to TopNav and homepage footer

---

## Routes

| Route | Description |
|---|---|
| `/changelog` | Three-tab page: What's New / What's Next / Give Feedback |
| `/feedback` | Standalone feedback page — full-width `FeedbackForm` |
| `/admin/feedback` | Admin table of feedback submissions |

Tab state on `/changelog` is driven by URL hash (`#whats-new`, `#whats-next`, `#give-feedback`) so tabs are deep-linkable. When no hash is present, the default active tab is **What's New**. The "Don't see what you need? Give us feedback →" nudge on the roadmap tab links to `#give-feedback`.

### Middleware

`/changelog` and `/feedback` are public routes — no authentication required. Both must be added to `isPublicPath()` in `middleware.ts` so they remain accessible when `LAUNCH_ONLY_ROOT=true`. The Next.js proxy routes `/api/feedback` (POST) and `/api/roadmap/votes` (GET) require no auth and will pass through middleware as-is since they are not prefixed with `/api/admin` or matched by `isProtectedLaunchPath()`. This is intentional and requires no middleware change for those API routes.

## Sanity Schema (two new document types)

### `changelogEntry`

| Field | Type | Notes |
|---|---|---|
| `title` | string | Display title of the release |
| `version` | string | e.g. `v0.4` |
| `publishedAt` | datetime | Controls ordering and display date |
| `tags` | array of string | Values: `feature`, `fix`, `improvement` |
| `body` | Portable Text | Rich text body |

### `roadmapItem`

| Field | Type | Notes |
|---|---|---|
| `title` | string | Short item title |
| `description` | text | Plain-text description |
| `status` | string enum | `planned` \| `in-progress` \| `shipped` |
| `order` | number | Manual sort order within each status group |

Both use the existing Sanity project (`zal102rv`, dataset `production`). GROQ query strings are added to `lib/sanity.ts` alongside the existing `postsQuery`. The RSC page **must call `sanityFetch()` from `lib/sanityFetch.ts`** to execute those queries — not `client.fetch()` from the Sanity client directly. This is the same pattern used by the guides page and is required for correct behaviour in Docker/server environments where CDN DNS resolution fails.

Pages use `export const revalidate = 60` ISR, consistent with guides.

The Sanity `_id` of each `roadmapItem` serves as the foreign key in Spring Boot's votes table — no additional ID field required. Sanity `_id` values are stable UUIDs.

### GROQ Query Filters

- `changelogEntriesQuery`: filter `_type == "changelogEntry" && publishedAt <= now()`, order by `publishedAt desc`
- `roadmapItemsQuery`: filter `_type == "roadmapItem" && status != "shipped"`, order by `order asc` within each status group. **Shipped items are excluded from the roadmap query** — when an item ships, the author changes its status to `shipped` in Sanity and creates a corresponding `changelogEntry`. The roadmap tab never displays shipped items.

## Spring Boot Backend

### New Tables

**`feedback`**

| Column | Type | Notes |
|---|---|---|
| `id` | UUID, PK | |
| `category` | enum | `BUG`, `FEATURE_REQUEST`, `GENERAL` |
| `message` | text | Max 1000 chars, enforced at API level |
| `email` | varchar, nullable | Optional follow-up email |
| `ip_address` | varchar | Captured server-side for spam visibility |
| `user_agent` | varchar | Captured server-side for spam visibility |
| `reviewed` | boolean, default false | Admin marks reviewed |
| `created_at` | timestamp | |

Rate limiting on `POST /api/v1/feedback` is deferred — IP and user agent capture provides enough visibility for manual spam review at this scale.

**`roadmap_votes`**

| Column | Type | Notes |
|---|---|---|
| `user_id` | UUID, FK → users | Part of composite PK |
| `sanity_item_id` | varchar | Part of composite PK; Sanity `_id` of the roadmap item |
| `created_at` | timestamp | |
| | PRIMARY KEY(user_id, sanity_item_id) | Composite PK — enforces one vote per user per item |

### New API Endpoints (Spring Boot)

| Method | Path | Auth | Notes |
|---|---|---|---|
| `POST` | `/api/v1/feedback` | None | Creates feedback record; captures IP + user agent server-side |
| `GET` | `/api/v1/roadmap/votes?ids=...` | Optional | Returns vote counts + current user's voted state for a list of Sanity IDs. For unauthenticated callers, returns vote counts with `voted: false` for all items — never 401. |
| `POST` | `/api/v1/roadmap/{sanityId}/vote` | Required | Toggles vote on/off; returns new count and voted state |

### Next.js Proxy Routes

All three endpoints are proxied via `app/api/` — client code never calls Spring Boot directly, consistent with the existing proxy pattern.

| Next.js route | Proxies to |
|---|---|
| `POST /api/feedback` | `POST /api/v1/feedback` |
| `GET /api/roadmap/votes` | `GET /api/v1/roadmap/votes` |
| `POST /api/roadmap/[sanityId]/vote` | `POST /api/v1/roadmap/:id/vote` |

The Next.js proxy for `POST /api/feedback` captures `x-forwarded-for` and `user-agent` from the incoming request headers and forwards them to Spring Boot — the client form never sends these values.

## Frontend Components

### New Files

| File | Type | Responsibility |
|---|---|---|
| `app/(app)/changelog/page.tsx` | RSC | Fetches Sanity changelog + roadmap data via `sanityFetch`, renders tab shell + passes data as props |
| `components/ChangelogTabs.tsx` | `"use client"` | Hash-based tab switcher (default: `#whats-new`), renders all three tab panels |
| `components/RoadmapItem.tsx` | `"use client"` | Single roadmap item with optimistic upvote toggle |
| `components/FeedbackForm.tsx` | `"use client"` | Shared form (category + message + email), posts to `/api/feedback` |
| `components/FeedbackModal.tsx` | `"use client"` | Backdrop + dialog wrapper around `FeedbackForm` |
| `app/(app)/feedback/page.tsx` | RSC | Standalone page rendering `FeedbackForm` full-width |
| `app/admin/feedback/page.tsx` | RSC | Admin table of submissions, sortable + filterable |
| `app/api/feedback/route.ts` | API route | Proxy to Spring Boot; forwards IP + user-agent headers |
| `app/api/roadmap/votes/route.ts` | API route | Proxy to Spring Boot |
| `app/api/roadmap/[sanityId]/vote/route.ts` | API route | Proxy to Spring Boot |

### Modified Files

| File | Change |
|---|---|
| `lib/sanity.ts` | Add `changelogEntriesQuery` and `roadmapItemsQuery` |
| `middleware.ts` | Add `/changelog` and `/feedback` to `isPublicPath()` |
| `components/TopNav.tsx` | Add "Send Feedback" ghost button; modal open state is local to `TopNav` via `useState` |
| `app/page.tsx` | Add "Send Feedback" link to the homepage's inline footer (homepage-only; this is intentional — TopNav covers all other pages) |

### FeedbackModal State

`FeedbackModal` open/close state is managed locally in `TopNav` with `useState`. No global context or portal is required — the modal renders inside `TopNav`'s JSX and is positioned fixed via CSS. This is sufficient given "Send Feedback" is the only trigger point in the nav.

## UI Design

### `/changelog` Page Header

```
BATTL BUILDERS            (small caps label)
Updates                   (h1)
What we've shipped and what's coming next.   (subhead)

[ What's New ] [ What's Next ] [ Give Feedback ]   (tab bar, amber underline on active)
```

### What's New Tab

Two-column entry layout: left column is version + date (120px fixed), right column is tags + title + body. Entries separated by bottom border, ordered newest first.

Tag values rendered as small pill badges:
- `feature` → amber
- `fix` → green
- `improvement` → blue

### What's Next Tab

Items grouped under "In Progress" and "Planned" headings. Shipped items are never shown here (filtered out in the GROQ query). Each item is a card with:
- **Left:** upvote button (chevron up + count) — bordered pill, amber when voted
- **Center:** title + description
- **Right:** status badge (In Progress = amber, Planned = muted)

Unauthenticated users clicking upvote are prompted to sign in (toast). Voted state is toggled optimistically — rolls back on error.

Footer nudge: *"Don't see what you need? Give us feedback →"* links to `#give-feedback`.

### Give Feedback Tab & `/feedback` Page

Full-width form:
- Category + email in a two-column row
- Message textarea (full width, 1000 char limit with counter)
- Submit button bottom-right, privacy note bottom-left

### Feedback Modal

Triggered by "Send Feedback" in TopNav and homepage inline footer. Same fields as the tab form. Full-width submit button inside the modal.

---

## Admin View (`/admin/feedback`)

Table with columns: Date, Category, Message (truncated to 120 characters), Email, Reviewed. Sortable by date. Filterable by category (Bug / Feature / General) and reviewed status. Follows existing admin page patterns.

---

## Feedback Form Fields

| Field | Required | Validation |
|---|---|---|
| Category | Yes | One of: Bug report, Feature request, General feedback |
| Message | Yes | 1–1000 characters |
| Email | No | Valid email format if provided |

`ip_address` and `user_agent` are captured server-side in the Next.js proxy route — never sent from the client form.

---

## SEO Metadata

Both `/changelog` and `/feedback` export a `metadata` object following the existing page pattern:

- `/changelog`: `title: "What's New — Battl Builders"`, relevant description
- `/feedback`: `title: "Send Feedback — Battl Builders"`, relevant description

---

## Out of Scope

- Email notifications when feedback is submitted (separate task)
- Sorting roadmap items by vote count (manual `order` field only for now)
- Public display of vote counts on the changelog tab
- Sanity Studio schema deployment (handled separately via Sanity CLI)
- Spring Boot entity/migration code (lives in `ballistic-builder-spring` repo, tracked separately)
- Rate limiting on the feedback endpoint (deferred; IP capture provides visibility at current scale)
