-# KISS Go Media Player — Implementation Plan
-
-## Overview
-A self-hosted, Kubernetes-deployable web media player written in Go (stdlib `net/http`) with a SQLite backend, vanilla JavaScript PWA frontend, and progressive offline capability. Designed for **KISS** (Keep It Stupidly Simple): minimal dependencies, zero frontend frameworks, fully interface-driven for testability.
-
-**Target test coverage:** >80% using dependency injection, hand-written mocks, and SQLite `:memory:` instances.
-
----
-
-## Architecture
-
-- **Backend:** Go 1.23, `net/http`, stdlib + `modernc.org/sqlite`
-- **Frontend:** Vanilla JS, CSS Custom Properties, HTML5 `<video>`/`<audio>` custom overlay controls
-- **Build:** Mage (`Magefile.go`) with `Build`, `Test`, `Install` targets
-- **Deploy:** Multi-stage `Dockerfile`; K8s `Deployment` + `Service` + two PVCs (`/data`, `/media`)
-- **Storage:** SQLite on `/data`; media library on `/media`; `ffmpeg`/`ffprobe` installed in runtime image

-## Feature Details
-
-### 1. Sets and Scanner
-- **Set** = immediate child directory of `MEDIA_ROOT`.
-- Scanner walks each set **recursively**.
-- `ffprobe` extracts duration, codec, resolution, bitrate.
-- `os.Stat` gets `file_size_bytes`.
-- `ffmpeg` generates thumbnail at ~10s (input-side seek `-ss`).
-- Audio files render as **compact text rows** in UI (no thumbnail for single audio items).
-- Sets display a **cover thumbnail** (`.cover.jpg` in set root) derived from a random video frame inside the set.
-
-### 2. Auth
-- `golang.org/x/crypto/bcrypt` for password hashing.
-- HTTP-only cookie sessions stored in `sessions` table.
-- **Bootstrap**: If `users` is empty, all routes redirect to `/bootstrap.html` until first admin is created.
-
-### 3. Roles
-- `set_permissions.role` = `owner` or `viewer`.
-- **Owner/admin** can upload to that set.
-- Admin sees all sets implicitly.
-
-### 4. Playback
-- Custom `<video>`/`<audio>` overlay with play/pause, seek bar, volume, mute, time, fullscreen toggle.
-- **Fullscreen** (`f` key) uses Fullscreen API on the **wrapper container** so overlay controls (including progress bar) remain visible.
-- **Auto-next**: On playback end, play next item from the current filtered/sorted/shuffled result set.
-
-### 5. Playback Counter
-- Client POSTs `position_seconds` every 3 seconds while playing.
-- Server tracks `delta = new_pos - last_position`, clamped to `[0, 12]`.
-- After cumulative `>= 60` seconds and `counted = false`, increments `media.play_count`.
-
-### 6. Keyboard Navigation
-- `↑↓` or `kj` — navigate media list.
-- `←→` or `hl` — switch sets/pages.
-- `Enter` — open selected media.
-- `p` or `Space` — play/pause/switch to selected.
-- `f` — toggle fullscreen.
-- `Esc` — exit fullscreen or deselect.
-- `r` — toggle shuffle on current filtered result set (lost on refresh).
-- `s` — generate share link for selected media.
-- `/` — trigger universal search input.
-
-### 7. Selection
-- `.selected` class highlights the focused media card.
-- Keyboard focus and mouse click both update selection.
-- Visually distinct from `.playing` (which shows a play indicator).
-
-### 8. Filtering
-- **Query params**: `set_id`, `type`, `search` (filename/substring), `tags` (AND logic, comma-separated), `favorites=true`, `min_duration`, `max_duration` (seconds).
-- **Sort**: `name`, `date`, `duration`, `play_count`, `random`.
-- **Search (`/`)**: Debounced 300ms. Searches filename, rel_path, codec, resolution, tags, notes, sets.
-
-### 9. Upload
-- `POST /api/sets/:id/upload` with `multipart/form-data`.
-- Max file size: **100MB** (`MAX_UPLOAD_SIZE_MB=100`).
-- If filename exists, append `(1)`, `(2)`, etc.
-- After save, immediate `ffprobe` + `ffmpeg` thumbnail + insert into `media`.
-
-### 10. Share Links
-- `POST /api/media/:id/shares` generates a new random token.
-- Default expiration: **7 days** from now.
-- Public routes `/s/:token` and `/s/:token/stream` bypass auth.
-- Each time `s` is pressed, a **new share** is created (old ones remain valid until expiry).
-
-### 11. Soft Delete + GC
-- `DELETE /api/media/:id` sets `deleted_at = NOW()`.
-- Media hidden from normal views; shown in admin trash view.
-- Admin/owner can restore before 7 days.
-- Background goroutine (`time.Ticker`, default every 30 minutes) selects items where `deleted_at < NOW() - 7 days`.
-- Physical file deleted via `os.Remove()`, then **hard DELETE** from DB row.
-
-### 12. Thumbnail Regeneration
-- `POST /api/media/:id/thumbnail` or set cover regeneration.
-- Random offset `rand.Float64() * duration`; `ffmpeg -ss` input-side seek.
-- Overwrites existing file.
-
-### 13. Per-Media Notes
-- Private **per-user** notes via `media_notes` table.
-- UI: notes icon on media detail opens textarea modal.
-- Auto-save or explicit save button.
-
-### 14. Theming + Dark Mode
-- All colors defined in `css/theme.css` using `var(--*)`.
-- No inline styles anywhere.
-- Sun/moon toggle in header swaps `<link>` tag to `light.css`.
-- Zero color literals in component styles.
-
-### 15. PWA
-- `manifest.json` for installable app.
-- Service Worker caches static assets for offline.
-- App works as standalone install on mobile/desktop.
-
----
-
-## Testability Requirements
-
-- **Dependencies injected via constructors** (no package-level vars).
-- **Interfaces at all boundaries**: DB, FS, `ffprobe`, `ffmpeg`, bcrypt, clock, sessions.
-- **Heavy unit tests** with `:memory:` SQLite for repository layer.
-- **Mock-based tests** for service layer using hand-written fakes.
-- **HTTP tests** with `httptest` + mocked services for handlers.
-- **Target:** >80% coverage via `go test ./... -race -coverprofile=cov.out`.
-
----
-
-## Kubernetes Deployment
-
-- **Image**: Multi-stage Dockerfile; final stage based on `alpine` with `apk add ffmpeg`.
-- **Security**: non-root user (`65534:65534`), `runAsNonRoot: true`, `fsGroup: 65534`.
-- **PVCs**: Separate volumes for `/data` (SQLite) and `/media` (library).
-- **Probes**: `/healthz` (liveness, no DB), `/readyz` (readiness, DB ping).
-- **Graceful shutdown**: Handle `SIGTERM`, close DB, finish active requests.
