# MediaShelf

A self-hosted web app for figuring out which of the thousands of files in a Plex library
are actually worth keeping.

MediaShelf scans a Plex Media Server over its HTTP API and pulls watch history from
Tautulli, builds a local snapshot of every movie and TV season, and joins together facts
that are never shown side by side — date added, size on disk, file path, owning library,
watch count, last watched, and *how much of it anyone actually finished* — into a
sortable, filterable, chartable grid with a tunable **reclaim score** that ranks deletion
candidates.

## Status

**v1 is report-only.** MediaShelf does not delete, move, or modify anything. It produces
a ranked list, saved rule sets, and CSV export. Deletion is designed for in the roadmap
but deliberately not built, so the scanner and the scoring model can be trusted before
anything destructive is wired up.

Nothing is implemented yet — this repository holds the design plus the read-only tools
used to validate it. The design has been checked against the live servers: 65.7 TB across
24 libraries, 2,930 movies and 2,807 TV seasons, 87,640 logged plays from 60 users, and
27.4 TB never played. See `docs/design.md` §2.1.

## What it does

- Full-library ingest from Plex, no agent on the Plex host, no filesystem mounts
- Movies at item level, TV rolled up to **season** level
- Watch data from **Tautulli**, so plays by *every* account are counted and a play that
  was abandoned after five minutes is distinguished from one that was finished — Plex's
  own history reports those identically. Falls back to Plex session history if Tautulli
  is unavailable, and says so rather than degrading silently
- Sort and filter on every metric; charts for size by library, additions over time,
  finished vs. abandoned vs. never-opened by size, and size vs. last-watched
- A weighted reclaim score with live sliders, and grace rules so it never recommends
  something you added last week
- Named, re-runnable saved views — *"unwatched, older than 2 years, over 10 GB"*,
  *"two people started it and nobody finished it"*
- CSV export of any view

## Planned stack

Python + Flask, SQLite (WAL), vanilla JS front-end, single container deployed as a
Portainer stack behind Nginx Proxy Manager.

## Roadmap

- **v2** — two-stage quarantine-then-purge deletion, with authentication, a path
  allowlist, and an audit log
- **v3** — Emby and Jellyfin support behind the existing `MediaProvider` abstraction

## Validating the design first

Plex and Tautulli are both LAN-only, so `tools/probe.py` exists to check this design
against real data from inside the network. It is **read-only** — GET requests only,
nothing is modified — and has no dependencies beyond the standard library.

```bash
export PLEX_BASE_URL=http://192.168.1.10:32400
export PLEX_TOKEN=...
export TAUTULLI_BASE_URL=http://192.168.1.100:8181
export TAUTULLI_API_KEY=...

python3 tools/probe.py                        # library shapes, sizes, coverage horizon
python3 tools/probe.py --dump inventory.json  # plus a full item inventory
python3 tools/reclaim_preview.py              # the actual reclaim numbers
```

`reclaim_preview.py` joins Plex sizes to Tautulli plays the way the application will, and
reports never-played bytes per library — split into the *confident* pool (added while
Tautulli was watching, never played) and the *uncertain* pool (predates Tautulli, might
have been watched). It also prints the largest never-played TV seasons and the
watcher-count distribution used to calibrate the score.

It reports Tautulli's coverage horizon, the finished/abandoned/never-opened split across
real plays, library shapes and sizes, path roots, multi-version items, and whether
Tautulli is actually watching the Plex server you think it is. Credentials are redacted
from all output including error messages, so the result is safe to paste anywhere.
