Release v1.6.0

Major feature release bringing technical-debt remediation, service extraction, frontend migration, and staged history loading.

### Added
- Staged history loading with SSE push — history data from Sonarr/Radarr is now fetched in stages; history-update SSE events push incremental results to the dashboard
- Frontend unit tests — added Vitest + jsdom test suite covering client/src/ modules
- Comprehensive tests for staged history loading — backend tests verify background-fetch behaviour, cache TTL handling, and SSE emission
- Integration test coverage — new integration and unit tests for dashboard, emby, sonarr, radarr, and sabnzbd routes

### Changed
- Technical-debt remediation — service extraction — extracted matching and assembly logic from monolithic dashboard.js (~1,360 lines → ~284 lines) into dedicated services: DownloadMatcher.js, DownloadAssembler.js, DownloadBuilder.js, TagMatcher.js, WebhookStatus.js
- Frontend architecture — migrated from monolithic public/app.js to vanilla ES modules under client/src/, bundled by Vite
- History pagination — replaced custom date-based cursor pagination with retriever's built-in pagination (pageSize=100, up to 10 pages / 1,000 records total)
- Status endpoint path — admin status route moved from /api/status/status to /api/status
- Background-fetch safety — poller no longer overwrites cache with empty data when background fetch fails
- SABnzbd progress calculation — progress computed from slot.mb and slot.mbleft / mbmissing
- Speed formatting consistency — updateDownloadCard() now calls formatSpeed() for uniform units
- Status-panel error handling — panel now surfaces error messages instead of blank box

### Fixed
- CSRF token reference errors — fixed ReferenceError bugs in api.js, auth.js, and blocklist handler
- Logout button — fixed undefined variable references
- Missing progress bar for SABnzbd — SABnzbd downloads now render correct progress bar
- Status route 404 — corrected Express router mount
- Status button DOM ID — fixed element-ID mismatch
- Tab selection — fixed to use data-tab attributes
- CSP violations and ignoreAvailable reference error
- Docker client-build stage — removed client/ from .dockerignore
- Unmatched torrent exclusion — torrents not matching Sonarr/Radarr record now correctly omitted
- Blocklist button CSRF — fixed ReferenceError

### Breaking Changes
- Unmatched torrents are no longer displayed — torrents that do not match a Sonarr/Radarr queue or history record are excluded
- Frontend build process changed — monolithic public/app.js source replaced by Vite build from client/src/
- Status API endpoint path changed — admin status endpoint moved from /api/status/status to /api/status

+### 3.3 Download Matching & Assembly Services
+
+#### Overview
+
+The `server/services/` directory contains pure, testable services that transform raw cache data into user-facing download objects. These were extracted from `dashboard.js` during the technical-debt remediation, reducing the route file from ~1,360 lines to ~284 lines.

+```
+
+#### Matching priority
+
+For each download item, the matcher attempts matches in priority order:
+
+1. **Stable ID match** — `downloadId` on SABnzbd slots is compared against Sonarr/Radarr queue/history `downloadId` fields (most reliable).
+2. **Title substring match** — bidirectional, case-insensitive substring check between the download name and the *arr `title` / `sourceTitle`.
+3. **Normalised title match** — dots replaced with spaces to handle release-name vs display-title mismatches.
+
+Unmatched torrents are **not** included in the response (fixed in develop-refactor2).
+
+#### Deduplication
+
+`DownloadBuilder.buildUserDownloads()` deduplicates by `${type}:${title}` so the same download does not appear twice when it is present in both queue and history.

+#### Replay protection improvements

+The replay cache uses an atomic `Set`-based deduplication key (`{eventType}:{instanceName}:{date}`) with a 5-minute TTL. `instanceName` precision was tightened so that events from different *arr instances are never incorrectly flagged as duplicates.

 ### 5.4 Download Matching Pipeline
 
 For each connected user the server:
 
 1. Reads all `poll:*` keys from `MemoryCache`.
 2. Builds `seriesMap`, `moviesMap`, `sonarrTagMap`, and `radarrTagMap` from embedded objects in queue records.
-3. For each SABnzbd/qBittorrent download item, attempts matches in priority order: Sonarr queue → Radarr queue → Sonarr history → Radarr history.
-4. Title matching is a **bidirectional, case-insensitive substring match**: `rTitle.includes(dlTitle) || dlTitle.includes(rTitle)`.
-5. For each match, resolves the series/movie, extracts user tags, checks ownership.
-6. Returns only the requesting user's downloads (or all, if admin with `showAll=true`).
+3. Delegates to `DownloadBuilder.buildUserDownloads(cacheSnapshot, options)`, which orchestrates:
+   - `DownloadMatcher.matchSabSlots()` — matches active SABnzbd queue slots
+   - `DownloadMatcher.matchSabHistory()` — matches recent SABnzbd history slots
+   - `DownloadMatcher.matchTorrents()` — matches qBittorrent torrents
+4. Each matcher attempts matches in priority order:
+   - **Stable ID match** — `downloadId` compared against *arr `downloadId` (most reliable).
+   - **Bidirectional title substring match** — case-insensitive `rTitle.includes(dlTitle) || dlTitle.includes(rTitle)`.
+   - **Normalised title match** — dots replaced with spaces for release-name vs display-title mismatches.
+5. Unmatched torrents are excluded; matched results are deduplicated by `${type}:${title}`.
+6. For each match, `DownloadAssembler` resolves cover art, episodes, import issues, blocklist eligibility, and admin fields.
+7. `TagMatcher` extracts user tags and checks ownership.
+8. Returns only the requesting user's downloads (or all, if admin with `showAll=true`).

Exports `classifySonarrEvent` / `classifyRadarrEvent` (returns `'imported'` | `'failed'` | `'other'`), `invalidateHistoryCache`, and `onHistoryUpdate` / `emitHistoryUpdate` for SSE staging.
+
+**Staged loading** — the fetcher returns up to `INITIAL_PAGE_SIZE` (100) records immediately from the cache or a quick fetch. If fewer than `MAX_TOTAL_RECORDS` (1,000) are present, a background fetch of up to `MAX_PAGES` (10) is triggered automatically. As the background fetch completes, `emitHistoryUpdate()` notifies all registered subscribers, which causes the SSE layer to push a `history-update` frame to every connected browser. The frontend (`client/src/ui/history.js`) listens for these events and re-renders the "Recently Completed" tab incrementally.
 
 **`server/routes/history.js`** (`GET /api/history/recent`) returns recently completed (imported or failed) downloads filtered for the authenticated user. Supports `?days=N` (default `RECENT_COMPLETED_DAYS`, capped at 90) and `?showAll=true` for admins. Results are sorted newest first.

+| `sse.js` | `startSSE()`, `stopSSE()` — EventSource lifecycle and auto-reconnect |
+| `downloads.js` | `renderDownloads()`, `createDownloadCard()`, `updateDownloadCard()` — diff-based DOM; client-logo and tag-badge helpers deduplicated |

-#### Tag badge rendering
+#### CSP compliance
 
-- **Regular user view** — a single accent-coloured badge showing the tag label that matched the current user's username (via `matchedUserTag`).
-- **Admin `showAll` view** — all tags on the download are rendered using `tagBadges[]`: tags with no matching Emby user → amber badge (leftmost); tags matched to a known Emby user → accent badge showing the Emby display name (rightmost).
+All UI modules use CSS class toggling (`.hidden`) instead of inline `style.display` to comply with the strict Content-Security-Policy enforced by Helmet.
+
+#### Download Client Filter
+
+The Active Downloads tab includes a multi-select dropdown filter that allows users to:
+- View all download clients with their type displayed as "Client Name (type)"
+- Select multiple clients to filter the downloads list
+- Use "Select All" / "Deselect All" buttons for bulk operations
+- Persist selection across sessions via localStorage
+
+Related functions in `filters.js`:
+- `initDownloadClientFilter()` — Sets up dropdown toggle, click-outside handler, Select/Deselect All buttons
+- `updateDownloadClientFilter()` — Populates checkbox list with client name + type badges
+- `toggleClientSelection()` — Updates selection array and localStorage
+- `updateSelectedCountDisplay()` — Updates button text to show "All clients" / "1 selected" / "N selected"
+
+Downloads are sorted by client order (matching the configuration order) and filtered by the selected client IDs.

 ---
 
+## [1.6.0] - 2026-05-21
+
+### Added
+
+- **Staged history loading with SSE push** — history data from Sonarr/Radarr is now fetched in stages; `history-update` SSE events push incremental results to the dashboard so the "Recently Completed" tab populates without waiting for the full fetch.
+- **Frontend unit tests** — added Vitest + jsdom test suite covering `client/src/` modules (formatters, storage, state).
+- **Comprehensive tests for staged history loading** — backend tests verify the new background-fetch behaviour, cache TTL handling, and SSE emission.
+- **Integration test coverage** — new integration and unit tests for `dashboard`, `emby`, `sonarr`, `radarr`, and `sabnzbd` routes.
+
+### Changed
+
+- **Technical-debt remediation — service extraction** — extracted matching and assembly logic from the monolithic `dashboard.js` (~1,360 lines → ~284 lines) into dedicated, testable services:
+  - `DownloadMatcher.js` — SABnzbd slot / torrent → *arr record matching
+  - `DownloadAssembler.js` — cover-art, episode, link, blocklist-eligibility helpers
+  - `DownloadBuilder.js` — orchestrator that reads the cache snapshot and builds the final user-facing download list
+  - `TagMatcher.js` — tag extraction, sanitisation, and user-ownership matching
+  - `WebhookStatus.js` — webhook configuration status aggregation
+- **Frontend architecture** — migrated from a monolithic `public/app.js` to vanilla ES modules under `client/src/`, bundled by Vite into `public/app.js`.
+- **History pagination** — replaced custom date-based cursor pagination with the retriever's built-in pagination (`pageSize=100`, up to 10 pages / 1,000 records total). Eliminates the 40-second response-time regression seen with large histories.
+- **Status endpoint path** — admin status route moved from `/api/status/status` to `/api/status` for consistency with the router mount point.
+- **Background-fetch safety** — the poller no longer overwrites the cache with empty data when a background history fetch fails or returns no records.
+- **SABnzbd progress calculation** — progress is now computed from `slot.mb` and `slot.mbleft` / `slot.mbmissing` because the SABnzbd queue API does not expose a `percentage` field.
+- **Speed formatting consistency** — `updateDownloadCard()` now calls `formatSpeed()` so all speed values display with uniform units (B/s, KB/s, MB/s, GB/s).
+- **Status-panel error handling** — the panel now surfaces error messages (e.g. `403` for non-admin users) instead of showing a blank box.
+
+### Fixed
+
+- **CSRF token reference errors** — fixed `ReferenceError` bugs in `api.js`, `auth.js`, and the blocklist handler where `csrfToken` and `currentUser` were accessed as bare variables instead of via the shared `state` object.
+- **Logout button** — fixed undefined variable references in `handleLogoutClick` that prevented the logout flow from completing.
+- **Missing progress bar for SABnzbd** — SABnzbd downloads now render a correct progress bar instead of showing `undefined%`.
+- **Status route 404** — corrected the Express router mount so `GET /api/status` responds instead of returning HTML 404.
+- **Status button DOM ID** — fixed element-ID mismatch (`status-btn` vs `status-toggle`) that prevented the admin status button from toggling the panel.
+- **Tab selection** — fixed tab switching to use `data-tab` attributes after the DOM IDs were removed during the ES-module migration.
+- **CSP violations and `ignoreAvailable` reference error** — resolved frontend CSP compliance issues and a missing-variable error in the history tab.
+- **Docker client-build stage** — removed `client/` from `.dockerignore` so the multi-stage Dockerfile can run the Vite build during image creation.
+- **Unmatched torrent exclusion** — torrents that cannot be matched to a Sonarr/Radarr record are now correctly omitted from the download display.
+- **Blocklist button CSRF** — fixed a `ReferenceError` that occurred when a non-admin user clicked the blocklist button.
+
+### Breaking Changes
+
+- **Unmatched torrents are no longer displayed** — torrents that do not match a Sonarr/Radarr queue or history record are excluded from the dashboard. Users who previously saw direct torrent-client downloads will no longer see them unless the *arr services track the item.
+- **Frontend build process changed** — the monolithic `public/app.js` source file has been replaced by a Vite build from `client/src/`. Any custom deployment scripts that copy or modify `public/app.js` directly must be updated to run `npm run build` (or use the provided Dockerfile, which already does this).
+- **Status API endpoint path changed** — the admin status endpoint moved from `/api/status/status` to `/api/status`. External integrations, monitoring checks, or scripts hitting the old path will receive `404`.
+
+---
+
+## [1.5.5] - 2026-05-20
+
+### Added
+
+- **Download client logos** — Added SVG logos for all supported download clients (SABnzbd, qBittorrent, Transmission, rTorrent, Deluge). Logos appear in the download client filter picker and on download cards.
+- **Download client logo in filter picker** — Multi-select download client filter now displays client logos alongside names for visual identification.
+- **Download client logo in download cards** — Download cards now display the client logo in the bottom-right corner (32×32px). Positioned absolutely within the card.
+- **SABnzbd speed display** — SABnzbd downloads now display the overall queue speed for the currently active download only. Speed is fetched from the client status API and applied to the downloading slot.
+- **Speed formatting** — Speed values are now formatted with appropriate units (B/s, KB/s, MB/s, GB/s) instead of raw bytes.
+
+### Fixed
+
+- **Missing pieces display for SABnzbd** — Removed incorrect "missing x of y" text display for SABnzbd downloads. This information is only relevant for torrent clients (qBittorrent, rTorrent) and is now only shown for those clients.
+- **Logo duplication on page reload** — Fixed download client logos and user tags appearing twice during page load. Updated `updateDownloadCard()` to remove old elements before adding new ones.
+- **Logo positioning** — Fixed download client logos appearing stacked at bottom-right of browser window instead of bottom-right of each card. Added `position: relative` to `.download-card` to provide proper positioning context.
+
+---
+
+## [1.5.4] - 2026-05-19
+
+### Added
+
+- **Multi-select download client filter** — Active Downloads tab now includes a dropdown filter that allows users to select multiple download clients. Shows client name and type (e.g., "Main (qbitt)"). Includes Select All / Deselect All buttons. Selection persists across sessions via localStorage.
+- **Download client ordering** — Downloads are now sorted by client order (matching the configuration order). Downloads from the first configured client appear first.
+- **Client metadata in downloads** — Download objects now include `client`, `instanceId`, and `instanceName` fields for client identification and filtering.
+- **SSE payload extension** — SSE stream now includes `downloadClients` array with all configured clients for UI ordering/filtering.
+- **Automatic migration** — Existing single-select filter selection automatically migrates to new multi-select format on first load.
+
+### Fixed
+
+- **SABnzbd size and speed display** — Fixed SABnzbd downloads showing undefined size and speed values. Now correctly uses `slot.mb` for size calculation and `slot.kbpersec` for per-slot speed from cached data.
+
+---
+
+## [1.5.3] - 2026-05-19
+
+### Fixed
+
+- **Status panel rendering regression** — the status panel was rendering as a small blank box due to an undefined `--background` CSS variable. Added the missing variable to all three themes (light, dark, mono).
+- **Status panel content destruction** — `showDashboard()` was calling `sp.innerHTML = ''` which destroyed the `status-content` div inside the status panel. Removed this destructive line.
+- **Webhooks panel visibility sync** — the webhooks panel was incorrectly visible on app load. Added explicit hiding of `webhooks-section` in `showDashboard()` to keep it in sync with the status panel (both show/hide together via `toggleStatusPanel()`).
+- **Webhooks panel DOM structure** — reverted webhooks-section to be a sibling of status-panel (not nested inside it), preventing innerHTML operations from affecting webhook elements.
+
+---
+
+## [1.5.2] - 2026-05-19
+
+### Fixed
+
+- **Status panel close button CSP compliance** — replaced inline `onclick` handler with `addEventListener` to comply with CSP nonce policy.
+
+---
+
 ## [1.5.1] - 2026-05-19
 
 ### Fixed

+ * Integration tests for server/routes/dashboard.js
+ *
+ * Strategy:
+ *  - createApp({ skipRateLimits: true }) for a real Express instance
+ *  - nock intercepts Emby auth so we can obtain a valid session cookie
+ *  - cache is seeded directly (same technique as history.test.js) so the
+ *    route's cache.get() calls return controlled fixture data without any
+ *    real outbound HTTP to SABnzbd / Sonarr / Radarr / qBittorrent
+ *  - nock is used for outbound axios calls made by the routes themselves
+ *    (cover-art proxy, blocklist-search, status webhook-check)
+ *
+ * Covers:
+ *  GET  /api/dashboard/user-downloads  — auth guard, SAB+Sonarr, SAB+Radarr,
+ *       qBittorrent, showAll (admin), empty cache, on-demand poll trigger,
+ *       paused queue speed, error propagation
+ *  GET  /api/dashboard/status          — admin-only guard, shape check
+ *  GET  /api/dashboard/webhook-metrics — any authenticated user
+ *  GET  /api/dashboard/cover-art       — missing url, non-http scheme, proxy, non-image
+ *  POST /api/dashboard/blocklist-search — admin guard, validation, sonarr+radarr paths

+ * Guard tests for server/services/DownloadBuilder.js
+ *
+ * This test file serves as a regression guard for the deduplicated download-assembly
+ * logic that will be extracted from dashboard.js into the DownloadBuilder service.
+ * The function buildUserDownloads does not exist yet - this test will pass once
+ * the implementation is complete in the next prompt.
+ *
+ * Coverage:
+ * - Happy path with matching downloads
+ * - Empty data scenarios
+ * - Mixed series and movies
+ * - Admin vs regular user permissions
+ * - showAll=true vs showAll=false filtering
+ * - Duplicate prevention (same download matched via multiple sources)
