# mplus-routes

Mythic+ route planner for Ascension classic-vanilla dungeons. Static web app
targeted at `mplus.exil.es`. Uses **Keystone.guru** map tiles + enemy data,
courtesy of RaiderIO (verbal permission, see attribution below).

## Stack

- **Maps:** keystone.guru z=4 tile pyramid stitched to 6144×4096 WebP per
  dungeon-floor (~150–600 KB each).
- **Data:** keystone.guru `mapcontext/data/<slug>/<mapping_id>/split_floors.js`
  — enemies (with positions, classification, NPC linkage), enemy packs
  (polygon outlines), enemy patrols (polylines), map icons (skulls, doors,
  comments, gateways), NPC names from companion `en_US.js`.
- **Frontend:** vanilla HTML/CSS/JS, single page, no build step. Pan/zoom
  via CSS transform on the canvas stage; SVG overlay in image-pixel space.
- **Hosting:** static. ~120 MB of WebPs total, committed to the repo. Drop
  behind nginx; no backend.

## Build

```bash
python3 -m venv .venv
.venv/bin/pip install Pillow

.venv/bin/python tools/kg_fetch.py --workers 32 --zoom 4   # fetch tiles + data (~1.3 GB raw)
.venv/bin/python tools/kg_stitch.py --workers 4            # → web/assets/maps/*.webp (~120 MB)
.venv/bin/python tools/kg_build_data.py                    # → web/assets/dungeons.json
```

## Run locally

```bash
cd web && python3 -m http.server 8765   # → http://localhost:8765/
```

## Deployment

Ansible role + playbook for `mplus.exil.es` live in
`/home/sub/repos/sub-net/ansible/roles/mplus_routes` and
`playbooks/setup_mplus_routes.yml`. Targets `exiles01:/srv/www/mplus.exil.es/`
behind the public HAProxy SNI router. The wildcard `*.exil.es` cert covers
TLS automatically.

First-time bring-up:
1. Add `mplus.exil.es` A/AAAA records in NetBox (→ public HAProxy VIPs)
2. Push the Ansible commit, trigger `Ansible_DeployPublicHaproxy`
3. Run `playbooks/setup_mplus_routes.yml` — `web/assets/maps/` ships in the
   repo, no pre-build step needed.

## Coverage

29 classic dungeons in the picker:

| Dungeon | Enemies | Packs | Map icons |
|---|---:|---:|---:|
| Ragefire Chasm | 139 | 9 | 1 |
| The Deadmines | 218 | 26 | 13 |
| Wailing Caverns | 261 | 18 | 8 |
| Shadowfang Keep | 140 | 6 | 5 |
| The Stockade | 94 | 21 | 5 |
| Blackfathom Deeps | 240 | 20 | 21 |
| Gnomeregan | 282 | 44 | 25 |
| Razorfen Kraul | 199 | 39 | 12 |
| Razorfen Downs | 219 | 53 | 12 |
| SM (4 wings) | 69+96+87+79 | 22+25+20+25 | 7+2+4+4 |
| Uldaman | 261 | 33 | 12 |
| Zul'Farrak | 302 | 40 | 6 |
| Maraudon | 548 | 107 | 4 |
| Blackrock Depths | 819 | 169 | 33 |
| Lower Blackrock Spire | 380 | 98 | 17 |
| Upper Blackrock Spire | 207 | 56 | 20 |
| Stratholme | 377 | 77 | 19 |
| Scholomance | 344 | 64 | 14 |
| Dire Maul (3 wings) | 229+300+241 | 58+44+48 | 7+7+10 |
| Naxxramas (40) | 574 | 92 | 2 |
| Molten Core | 241 | 39 | 1 |
| Blackwing Lair | 79 | 15 | 1 |
| Zul'Gurub | 0 | 0 | 0 |
| Sunken Temple | 0 | 0 | 0 |

ZG and Sunken Temple have map tiles but no enemy data — kg's mapping_id
search didn't find populated data for them at time of build. Picker still
lets you draw routes on the map manually.

## Attribution

Map tiles and enemy data derived from
[Keystone.guru](https://keystone.guru/) (RaiderIO, Inc.). Used with
permission from the maintainers for the Ascension community deployment at
`mplus.exil.es`. World of Warcraft trademarks belong to Blizzard
Entertainment; this site is not affiliated with Blizzard.

## Refresh data sources

Both kg's tiles and data update over time. To refresh:
- Re-run the wide mapping-id probe (`tools/` doesn't ship one — easiest is
  to fetch the kg homepage and find current ids, or re-run a probe like the
  one in `data/kg/_summary.json` headers note).
- Update `data/kg_dungeons.json` with new mapping_ids.
- Re-run `kg_fetch.py` → `kg_stitch.py` → `kg_build_data.py`.

## Known gaps

- 2/29 dungeons (Zul'Gurub, Sunken Temple) are present without enemy data.
- Multi-floor dungeons (LBRS 7, BWL 4, Naxx 6, etc.) have all floors mapped
  individually; the floor tabs in the UI let you switch between them.
- No trash-pull authoring beyond kg's data — packs are inherited as-is. For
  custom-routing ("skip this pack, take this one"), use the route+pull tools
  in the toolbar.
