@@ -43,6 +43,41 @@ Keep the game server bound to `127.0.0.1`. Set `TRUST_PROXY=1` only when the
 server can be reached solely through your local reverse proxy. This lets account
 limits use the visitor's public IP instead of the proxy's address.
 
+## Separate auth server
+
+The auth routes can run as their own Node process. This is useful when you want
+`auth.phenomrom.com` to stay available while the game server is being rebuilt or
+changed.
+
+On the TrueNAS host, run the auth process against the same project data folder:
+
+```sh
+npm ci
+npm run db:init
+AUTH_HOST=127.0.0.1 AUTH_PORT=4174 TRUST_PROXY=1 COOKIE_SECURE=1 AUTH_CORS_ORIGINS=https://phenomrom.com npm run auth:start
+```
+
+Point `auth.phenomrom.com` at that process through HTTPS:
+
+```caddyfile
+auth.phenomrom.com {
+  reverse_proxy 127.0.0.1:4174
+}
+```
+
+Build the web or mobile app with the auth base URL set separately from the game
+API:
+
+```sh
+VITE_AUTH_API_BASE_URL=https://auth.phenomrom.com npm run build
+```
+
+For a Capacitor wrapper, set `window.CAPACITOR_AUTH_API_BASE_URL` to
+`https://auth.phenomrom.com` the same way `window.CAPACITOR_API_BASE_URL` is set.
+The app stores the returned bearer token locally and sends it with later API
+requests, so auth works across subdomains and inside the mobile WebView. Existing
+same-origin cookie sessions still work when auth is served by the game server.

 ## Account limits
 
 Registration permits one account per public IP by default. Login and API rate

+# Gearing System
+
+## Goal
+
+Gearing should move from boss-specific multi-item drop tables to one clear currency loop:
+
+1. Kill bosses.
+2. Earn boss coins.
+3. Craft gear with those coins.
+4. Upgrade that boss gear into the next item-level tier with higher-rarity coins.
+
+This keeps boss loot readable, removes low-percentage frustration, and makes every boss kill progress a targeted gear goal.
+
+## Coin Tiers
+
+Coins are component items. Each coin is tied to a boss source and an item-level tier.
+
+| Item Level | Display Color | Rarity Key | Example |
+| --- | --- | --- | --- |
+| 5 | White | common | Bulldrome Coin |
+| 10 | Green | uncommon | Green Bulldrome Coin |
+| 15 | Blue | rare | Blue Bulldrome Coin |
+| 20 | Purple | epic | Purple Bulldrome Coin |
+| 25 | Orange | legendary | Orange Bulldrome Coin |
+
+Implementation note: the current TypeScript rarity union supports `common`, `uncommon`, `rare`, and `epic`. Orange needs a new rarity key, recommended as `legendary`, plus UI color styling.
+
+## Boss Loot
+
+Each boss has one loot roll.
+
+For now, each successful boss loot roll awards 1 to 3 coins:
+
+| Roll Result | Coins Awarded |
+| --- | --- |
+| Low roll | 1 coin |
+| Normal roll | 2 coins |
+| High roll | 3 coins |
+
+Recommended weighting:
+
+| Coins | Chance |
+| --- | --- |
+| 1 | 50% |
+| 2 | 35% |
+| 3 | 15% |
+
+The coin source comes from the defeated boss. Bulldrome drops Bulldrome coins, Rathian drops Rathian coins, and so on.
+
+The coin tier comes from content difficulty or roguelike depth:
+
+| Source | Coin Tier |
+| --- | --- |
+| Item level 5 content | White level 5 coins |
+| Item level 10 content | Green level 10 coins |
+| Item level 15 content | Blue level 15 coins |
+| Item level 20 content | Purple level 20 coins |
+| Item level 25 content | Orange level 25 coins |
+
+## Crafting Costs
+
+Gear is crafted with boss coins from the same boss and item-level tier.
+
+| Gear Item Level | Cost |
+| --- | --- |
+| 5 | 5 white boss coins |
+| 10 | 10 green boss coins |
+| 15 | 15 blue boss coins |
+| 20 | 20 purple boss coins |
+| 25 | 25 orange boss coins |
+
+Example:
+
+- Bulldrome item-level 5 helmet costs 5 white Bulldrome coins.
+- Bulldrome item-level 10 helmet costs 10 green Bulldrome coins.
+- Rathian item-level 20 gloves cost 20 purple Rathian coins.
+
+## Gear Upgrades
+
+Crafting can create gear directly, but upgrades should become the preferred long-term path.
+
+Upgrade rule:
+
+- Existing boss gear upgrades into the next item-level version of the same boss gear.
+- Upgrade cost uses coins from the next tier.
+- Required coin quantity equals the target item level.
+
+Examples:
+
+| Upgrade | Cost |
+| --- | --- |
+| Bulldrome item level 5 gear -> Bulldrome item level 10 gear | 10 green Bulldrome coins |
+| Bulldrome item level 10 gear -> Bulldrome item level 15 gear | 15 blue Bulldrome coins |
+| Bulldrome item level 15 gear -> Bulldrome item level 20 gear | 20 purple Bulldrome coins |
+| Bulldrome item level 20 gear -> Bulldrome item level 25 gear | 25 orange Bulldrome coins |
+
+Upgrade should consume the old item and award the upgraded item. This avoids duplicate clutter and keeps equipment identity clear.
+
+## Roguelike Loot
+
+Roguelike bosses should award coins when defeated, using the same 1 to 3 coin roll.
+
+Roguelike coin tier should scale by wave band:
+
+| Waves | Coin Tier |
+| --- | --- |
+| 1-4 | Level 5 white coins |
+| 5-9 | Level 10 green coins |
+| 10-14 | Level 15 blue coins |
+| 15-19 | Level 20 purple coins |
+| 20+ | Level 25 orange coins |
+
+Boss identity can be handled two ways:
+
+1. Boss-based coins: use the actual boss template selected for that roguelike boss.
+2. Roguelike coins: use a generic roguelike coin per tier.
+
+Recommended first pass: boss-based coins. It reuses the same crafting economy as dungeons and makes roguelike runs feel connected to the main gear chase.
+
+## Roguelike Checkpoints
+
+Checkpoints should unlock every 5 waves.
+
+| Highest Cleared Wave | Future Start Wave |
+| --- | --- |
+| 0-4 | 1 |
+| 5-9 | 5 |
+| 10-14 | 10 |
+| 15-19 | 15 |
+| 20+ | Highest unlocked 5-wave checkpoint |
+
+Checkpoint rule:
+
+- Unlock a checkpoint after clearing its boss band.
+- Starting from a checkpoint begins at that wave band with matching coin tier.
+- Runs should still record leaderboard progress from the selected start wave so full runs and checkpoint runs can be ranked separately later.
+
+Current implementation note: the roguelike screen always starts at stage 1 and only awards XP per boss. Checkpoints need saved character progress and a start-wave selector.
+
+## Current Code Fit
+
+The existing system already has most of the required foundation:
+
+- `items.slot = 'component'` can represent coins.
+- `character_inventory.quantity` already stacks components.
+- `crafting_recipes` and `crafting_recipe_components` already support coin costs.
+- `encounter_loot_rolls` and `encounter_loot_roll_items` already persist retry-safe loot awards.
+- `completeRoguelike` is already called after each roguelike boss kill for XP, so coin awards can attach to that same flow.
+
+Needed changes:
+
+- Replace current 4-component boss drop tables with one boss coin per boss per tier.
+- Change boss loot roll count from multiple chance slots to one 1-3 coin roll.
+- Add orange/legendary rarity support.
+- Add upgrade recipes or a dedicated upgrade endpoint.
+- Add roguelike boss coin awards.
+- Add roguelike checkpoint persistence and start-wave selection.
+- Export updated offline starter data after seed changes.
+
+## Suggestions
+
+Use guaranteed coin drops for now. One to three coins per boss gives steady progress and makes craft timing easy to understand.
+
+Keep coins boss-specific, not slot-specific. Slot-specific components add complexity without much decision value.
+
+Use upgrade-first UI. Show the next upgrade for equipped gear before showing the full crafting catalog.
+
+Keep direct crafting and upgrading at the same coin cost for the target tier. Direct crafting helps new slots catch up; upgrading preserves boss gear identity.
+
+Add a pity floor only if needed later. If boss kills always award coins, the system already has deterministic progress.
+
+Use one orange rarity key: `legendary`. Avoid storing display color names as rarity values; colors can change without data migration.
