feat(09-05): build + push botfights:1.2.0 to the vps2 registry

- Fixed a pre-existing pnpm overrides config drift (package.json's dead pnpm.overrides key vs pnpm-workspace.yaml's overrides, never fully migrated after commit bcb323e) that was blocking the docker build's `pnpm install --frozen-lockfile` step under a current pnpm version. Zero dependency specifier changes in the regenerated lockfile. - Built and pushed 146.59.87.168:3000/lfg2025/botfights:1.2.0 from botfight main @ 2a343ac (arena-proxy + nostr-only auth + unified prompt, all three wave-1 plans confirmed present before build). - Documented the build/push recipe, the gotcha, and the smoke test in docs/arena-deployment.md.

 disable-model-invocation: true
 allowed-tools: Bash, Read, Write, Edit, Glob, Grep
 argument-hint: "[app-name]"
 ---
 Add a new containerized app ($ARGUMENTS) to Archipelago.
 ## Steps
 ### 1. Create the manifest
 Create `apps/{app-id}/manifest.yml` following the spec in `docs/app-manifest-spec.md`:
 - `app.id` (kebab-case), `app.name`, `app.version` (SemVer)
 - `container.image` (pinned version, **NEVER** `latest`)
 - `security`: readonly_root, dropped capabilities, non-root UID > 1000
 - `health_check`, `dependencies`
 ### 2. Add app icon
 Place icon at `neode-ui/public/assets/img/app-icons/{app-id}.{png|webp|svg}`
 ### 3. Create status UI (if no native web UI)
 For apps without their own web interface, create a UI container in `docker/{app-id}-ui/` following the patterns in `.cursor/rules/APP-UI-STANDARDS.md`.
 Reference implementations:
 - Bitcoin UI: `docker/bitcoin-ui/`
 - LND UI: `docker/lnd-ui/`
 ### 4. Update backend
 - Add port mapping in `core/archipelago/src/container/docker_packages.rs`
 - Add env vars in `get_app_config()` in `core/archipelago/src/api/rpc.rs`
 ### 5. Deploy and test
 - Deploy: `./scripts/deploy-to-target.sh --live`
 - Install from marketplace UI at http://192.168.1.228
 - Verify it launches and auto-connects to dependencies
 - Check logs: `sudo podman logs {container-name}`
 ### 6. Security review
 - Verify readonly root, dropped caps, non-root user
 - Check network isolation
 - No hardcoded secrets

 Perform a security hardening pass on $ARGUMENTS (default: all).
 ## Backend Hardening (Rust)
 - [ ] No hardcoded credentials — check for Base64-encoded auth strings, passwords in source
 - [ ] Secrets use `core/security/secrets_manager.rs` — verify encryption is implemented (not plaintext)
 - [ ] All RPC endpoints validate inputs before processing
 - [ ] No `unwrap()` on user-supplied data — handle errors gracefully
 - [ ] Rate limiting on auth endpoints (login, password change)
 - [ ] Session tokens have proper expiry and rotation
 - [ ] File permissions: keys at 0o600, dirs at 0o700
 - [ ] Tracing never logs secrets, passwords, keys, or tokens
 ## Frontend Hardening (Vue/TypeScript)
 - [ ] No secrets in source (API keys, passwords, tokens)
 - [ ] No `eval()` or `innerHTML` with untrusted content
 - [ ] XSS prevention — sanitize all user inputs
 - [ ] CSRF protection on state-changing requests
 - [ ] Credentials use `credentials: 'include'` not localStorage tokens
 - [ ] No sensitive data in console.log statements
 ## Container Hardening
 - [ ] All manifests: `readonly_root: true` (unless documented exception)
 - [ ] All manifests: capabilities dropped, only required ones added
 - [ ] All manifests: non-root user (UID > 1000)
 - [ ] All manifests: `no-new-privileges: true`
 - [ ] All images pinned to specific versions (no `:latest`)
 - [ ] Network isolation — no `host` network unless required and documented
 - [ ] AppArmor profiles defined and enforced
 ## Script Hardening
 - [ ] All scripts use `set -euo pipefail`
 - [ ] No hardcoded passwords (use deploy-config.sh or env vars)
 - [ ] SSH uses proper key-based auth where possible
 - [ ] No `chmod 777` or overly permissive permissions
 - [ ] Temp files use `mktemp` not predictable paths
 Report all findings with file paths and line numbers. Fix issues directly where safe to do so. Flag anything that needs discussion.

 name: pwa-icon-cache-fix
 description: Use when the user reports a PWA icon not updating, stale PWA icon, wrong icon after install, or any PWA caching issue. Also applies when changing PWA icons in a Vite + vite-plugin-pwa project.
 version: 2.0.0
 ---
 # PWA Icon Cache Fix
 ## Problem
 PWA icons are cached at FOUR independent layers:
 1. **Service worker cache** (Workbox precache)
 2. **Browser HTTP cache**
 3. **Browser manifest resources** (Chromium stores resized icons in its profile data, keyed by a permanent extension ID tied to the origin — NEVER re-fetched even after uninstall/reinstall)
 4. **macOS .app bundle** (`.icns` file baked into the `.app` in `~/Applications/`)
 Query string cache busting (`?v=2`) and uninstall/reinstall do NOT fix this. Chromium reuses the same extension ID for the same origin, so it keeps the old cached icons.
 ## Fix Steps
 ### 1. Verify icon files on disk and server are correct
 ```bash
 # Visual check
 Read packages/app/public/pwa-192x192.png
 Read packages/app/public/pwa-512x512.png
 # Hash match check
 curl -s http://localhost:5173/pwa-192x192.png | md5
 md5 -q packages/app/public/pwa-192x192.png
 ```
 ### 2. Find the PWA's Chromium extension ID
 Read the installed `.app` bundle's `Info.plist` to get the `CrAppModeShortcutID`:
 ```bash
 plutil -p "~/Applications/Brave Browser Apps.localized/AIUI.app/Contents/Info.plist" | grep CrAppModeShortcutID
 ```
 This returns an ID like `idemibpphagihbobmgmaojhjfidlfpdl`.
 ### 3. Overwrite the cached icons in browser profile
 Chromium stores resized icons at:
 `~/Library/Application Support/BraveSoftware/Brave-Browser/Default/Web Applications/Manifest Resources/{ID}/Icons/`
 Overwrite every size using `sips`:
 ```bash
 ICON_DIR="~/Library/Application Support/BraveSoftware/Brave-Browser/Default/Web Applications/Manifest Resources/{ID}/Icons"
 SRC="packages/app/public/pwa-512x512.png"
 for size in 32 48 64 96 128 192 256 512; do
  sips -z $size $size "$SRC" --out "${ICON_DIR}/${size}.png"
 done
 ```
 ### 4. Rebuild the macOS .icns in the .app bundle
 ```bash
 ICONSET="/tmp/aiui.iconset"
 mkdir -p "$ICONSET"
 SRC="packages/app/public/pwa-512x512.png"
 sips -z 16 16 "$SRC" --out "$ICONSET/icon_16x16.png"
 sips -z 32 32 "$SRC" --out "$ICONSET/icon_16x16@2x.png"
 sips -z 32 32 "$SRC" --out "$ICONSET/icon_32x32.png"
 sips -z 64 64 "$SRC" --out "$ICONSET/icon_32x32@2x.png"
 sips -z 128 128 "$SRC" --out "$ICONSET/icon_128x128.png"
 sips -z 256 256 "$SRC" --out "$ICONSET/icon_128x128@2x.png"
 sips -z 256 256 "$SRC" --out "$ICONSET/icon_256x256.png"
 sips -z 512 512 "$SRC" --out "$ICONSET/icon_256x256@2x.png"
 sips -z 512 512 "$SRC" --out "$ICONSET/icon_512x512.png"
 cp "$SRC" "$ICONSET/icon_512x512@2x.png"
 iconutil -c icns "$ICONSET" -o "~/Applications/Brave Browser Apps.localized/AIUI.app/Contents/Resources/app.icns"
 ```
 ### 5. Flush macOS icon cache
 ```bash
 touch "~/Applications/Brave Browser Apps.localized/AIUI.app"
 killall Finder
 killall Dock
 ```
 ### 6. Bump PWA_CACHE_VERSION in main.ts
 Increment the `PWA_CACHE_VERSION` constant — this nukes all SW caches on next page load for web-layer caching.
 ### 7. Delete stale build artifacts
 Remove old `dist/` and `dev-dist/` SW/manifest files.
 ## Browser-Specific Paths
 - **Brave**: `~/Library/Application Support/BraveSoftware/Brave-Browser/Default/Web Applications/`
 - **Chrome**: `~/Library/Application Support/Google/Chrome/Default/Web Applications/`
 - **PWA apps (Brave)**: `~/Applications/Brave Browser Apps.localized/`
 - **PWA apps (Chrome)**: `~/Applications/Chrome Apps.localized/`
 ## Key Insight
 Chromium assigns a permanent extension ID per origin (e.g., `localhost:5173`). This ID persists across uninstall/reinstall. The icon cache in `Manifest Resources/{ID}/Icons/` is populated ONCE and never refreshed from the manifest. The only fix is to overwrite the files directly on disk.

 ## Checklist
 ### Rust Backend
 - [ ] No `unwrap()` or `expect()` — use `?` operator with context
 - [ ] Replace `#[allow(dead_code)]` — either use it or remove it
 - [ ] Functions under 50 lines, single responsibility
 - [ ] Custom error types per module with `thiserror`
 - [ ] `tracing` for logging — no `println!` or secrets in logs
 - [ ] Split files over 500 lines into focused modules
 - [ ] Run `cargo clippy --all-targets --all-features` mentally and fix issues
 ### Vue Frontend
 - [ ] Extract ALL inline Tailwind to global classes in `neode-ui/src/style.css`
 - [ ] Use semantic class names: `.glass-card`, `.info-card`, `.glass-button`, `.path-option-card`
 - [ ] Replace ALL `.gradient-button` with `.glass-button` (gradient buttons are BANNED)
 - [ ] Replace ALL `.gradient-card` / `.gradient-card-dark` with `.glass-card` or `.path-option-card`
 - [ ] Settings.vue is the gold standard — all screens should match its patterns
 - [ ] Replace `any` types with proper interfaces or `unknown`
 - [ ] Ensure `<script setup lang="ts">` on all components
 - [ ] Remove dead code (unused imports, components like HelloWorld.vue)
 - [ ] Remove all `TODO`/`FIXME` — fix now or create GitHub issues
 - [ ] Consolidate `console.log` calls to use a logging utility
 - [ ] Split views over 800 LOC into sub-components
 ### General
 - [ ] No hardcoded paths (`/Users/dorian/...`)
 - [ ] No hardcoded credentials — use env vars or secrets manager
 - [ ] Comment WHY not WHAT
 - [ ] Remove commented-out code entirely
 After refactoring, verify the code still compiles/type-checks. For frontend: `cd neode-ui && npm run type-check`. Do NOT deploy — leave that to `/deploy`.

 ## Backend Testing (Rust)
 ### Run existing tests
 ```bash
 # On dev server (never build Rust on macOS)
 sshpass -p 'EwPDR8q45l0Upx@' ssh -o StrictHostKeyChecking=no archipelago@192.168.1.228 \
  'source ~/.cargo/env && cd ~/archy/core && cargo test --all-features 2>&1'
 ```
 ### Creating new tests
 - Place unit tests in the same file with `#[cfg(test)]` module
 - Place integration tests in `core/{crate}/tests/`
 - Use `#[tokio::test]` for async tests
 - Mock external dependencies (filesystem, network, Podman)
 - Test error cases, not just happy paths
 - Aim for >80% coverage on core logic
 ### Priority areas needing tests
 1. RPC endpoint handlers (core/archipelago/src/api/)
 2. Manifest parsing (core/container/src/manifest.rs)
 3. Dependency resolver (core/container/src/dependency_resolver.rs)
 4. Auth flows (core/archipelago/src/auth.rs)
 5. Secrets manager (core/security/src/secrets_manager.rs)
 6. Port allocation (core/container/src/port_manager.rs)
 ## Frontend Testing (Vue/TypeScript)
 ### Setup (if not already configured)
 Ensure vitest is configured in `neode-ui/`:
 ```bash
 cd neode-ui && npm run test 2>&1 || echo "No test script configured"
 ```
 ### Creating new tests
 - Use Vitest + @vue/test-utils
 - Place tests in `neode-ui/src/__tests__/` or co-located `*.test.ts`
 - Test stores (Pinia) with `createTestingPinia()`
 - Test API clients with mocked fetch
 - Test component rendering and interactions
 - Test routing guards
 ### Priority areas needing tests
 1. Pinia stores (app.ts, container.ts, appLauncher.ts)
 2. RPC client (api/rpc-client.ts) — error handling, retry logic
 3. WebSocket client (api/websocket.ts) — reconnection
 4. Router guards — auth flow, session timeout
 5. Key components — ContainerStatus, SpotlightSearch
 Report test results and any new tests created.

 ---
 Review the UI of $ARGUMENTS against Archipelago's glassmorphism design system and UX standards.
 ## Design System Compliance
 ### Glass Classes (must use global classes from style.css)
 - [ ] Section containers use `.path-option-card cursor-default px-6 py-6` (Settings-style sections)
 - [ ] Content containers/modals use `.glass-card`
 - [ ] Interactive selectable cards use `.path-option-card` (with hover)
 - [ ] Status displays use `.info-card` (no hover effects)
 - [ ] ALL buttons use `.glass-button` — NEVER `.gradient-button` (BANNED)
 - [ ] Large primary actions use `.path-action-button`
 - [ ] Info sub-cards use `bg-black/20 rounded-xl border border-white/10`
 - [ ] Info rows use `bg-white/5 rounded-lg` pattern
 - [ ] Action buttons in info sections use `.info-card-button`
 ### BANNED — Flag These as Violations
 - [ ] No `.gradient-button` anywhere (replace with `.glass-button`)
 - [ ] No `.gradient-card` / `.gradient-card-dark` (replace with `.glass-card` or `.path-option-card`)
 ### NO Inline Tailwind
 - [ ] Check for long `class="..."` strings with layout/color utilities
 - [ ] Extract to semantic classes in `neode-ui/src/style.css`
 - [ ] Name classes semantically: `.app-card`, `.status-badge`, `.nav-item`
 ### Color Compliance
 - [ ] Primary text: `text-white/90` (not `text-white` or arbitrary opacity)
 - [ ] Muted text: `text-white/60` to `text-white/70`
 - [ ] Backgrounds: `rgba(0,0,0,0.60)` with `backdrop-filter: blur(24px)`
 - [ ] Borders: `rgba(255,255,255,0.18)` standard
 - [ ] Status colors: green=#4ade80, red=#ef4444, yellow=#facc15, blue=#3b82f6, orange=#fb923c
 ### Typography
 - [ ] Font: Avenir Next (body), Montserrat (headings via `font-archipelago`)
 - [ ] H1: text-3xl font-bold, H2: text-2xl font-semibold, H3: text-xl font-semibold
 - [ ] Body: text-base, Small: text-sm, Labels: text-xs
 ### Interaction States
 - [ ] Hover: `translateY(-2px)` lift + background brighten + enhanced shadow
 - [ ] Active: `translateY(1px)` press
 - [ ] Selected: brighter background + glow shadow + enhanced gradient border
 - [ ] Disabled: reduced opacity (~50%), no pointer events
 - [ ] Loading: spinner SVG + descriptive text, button disabled
 - [ ] Focus-visible: soft blue glow `rgba(120, 180, 255, 0.2)`
 ### Transitions
 - [ ] Standard: `all 0.3s ease`
 - [ ] All interactive elements have transitions (no jarring state changes)
 - [ ] Respect `prefers-reduced-motion`
 ### Spacing
 - [ ] 4px grid system (p-1=4px, p-2=8px, p-3=12px, p-4=16px)
 - [ ] 16px default padding on cards
 - [ ] Consistent gap values between grid items
 ### Responsive
 - [ ] Mobile: single column, reduced padding, touch targets >= 44x44px
 - [ ] Tablet (md:): two columns
 - [ ] Desktop (lg:): three columns, full effects
 ### Accessibility
 - [ ] Semantic HTML (`<button>`, `<nav>`, `<main>`, not div soup)
 - [ ] ARIA labels on icon-only buttons
 - [ ] Keyboard navigable (Tab order, Enter to activate, Esc to close)
 - [ ] Color contrast WCAG AA (4.5:1 normal text, 3:1 large)
 - [ ] Images have alt text (decorative: `alt=""`)
 ### Icons
 - [ ] Stroke-based SVGs, stroke-width 2.5 default
 - [ ] Color: `text-white/85` default, `text-white` on hover
 - [ ] Drop-shadow filter applied on interactive icons
 - [ ] Size: w-5 h-5 standard, w-4 h-4 small
 ## Service UI Review (if reviewing docker/*-ui/)
 - [ ] Uses `.glass-card` for main sections
 - [ ] Uses `.info-card` for status (no hover)
 - [ ] Uses `.info-card-button` for actions (with hover)
 - [ ] Uses `bg-white/5` for info rows
 - [ ] Header: logo + title + description + status
 - [ ] Background image loads correctly
 - [ ] Mobile responsive

-# BOTFIGHTS — Bot Setup Guide
+# BOTFIGHTS bot setup
-Your AI reads this file to set up a fighting bot for BOTFIGHTS. Follow the instructions for your chosen connection mode.
+The canonical AI bot-setup prompt lives at `frontend/public/docs/BOTFIGHTS.md` (served live at
-
+`GET /api/docs/prompt`). Read that file — this stub exists only so the two copies can't drift.
 ## Credentials
 You should have received these from BOTFIGHTS registration:
 ```
 BOT_ID=your_bot_id
 BOT_SECRET=your_bot_secret
 ```
 If the user provided credentials above, use those values. If not, ask the user for them.
 ## Choose a Mode
 - **Webhook** — BOTFIGHTS POSTs challenges to your server. Fastest response times. Requires a public URL.
 - **Polling** — Your bot polls BOTFIGHTS for challenges. No public URL needed. Just keep the script running.
 If the user didn't specify, **use polling** — it's simpler and works from any machine.

 ```
 ### Run it
 ```bash
 ANTHROPIC_API_KEY="sk-ant-your-key" BOT_SECRET="your-secret" node bot.js
 ```
 ### Expose publicly
 Your bot needs a public URL. Pick one:
 ```bash
 # localtunnel (free, quick)
 npx --yes localtunnel --port 3000
 # ngrok (more reliable)
 ngrok http 3000
 # cloudflared (Cloudflare tunnel)
 cloudflared tunnel --url http://localhost:3000
 ```
 Use the public URL as your webhook endpoint. If the user already registered with a webhook URL, you're done. If they need to update it, they can do so on BOTFIGHTS.
 ### Test it
 ```bash
 curl localhost:3000 -d '{"type":"webhook_test","challenge":"ping"}'
 # Should return: {"answer":"pong","trash_talk":"Always online."}
 ```

 ## How Fights Work
 1. BOTFIGHTS sends your bot a challenge (JSON)
 2. Your bot has a few seconds to respond with `{ "answer": "...", "trash_talk": "..." }`
 3. Answers scored on correctness and speed. 5-10 rounds per fight.
 4. For factual questions, give ONLY the answer — no explanation
 5. For creative challenges, be vivid and original. 100-400 chars.
 6. Speed matters: when two bots both answer correctly, the faster one wins
 ## Challenge Payload
 ```json
 {
  "fight_id": "f_abc123",
  "round": 1,
  "type": "speed_blitz",
  "challenge": "What is the capital of France?",
  "constraints": { "timeout_ms": 8000, "max_tokens": 500 },
  "opponent": { "name": "skull_crusher", "wins": 12, "losses": 3 },
  "arena": "neon_pit",
  "arena_modifier": "speed_2x"
 }
 ```
 Your response:
 ```json
 { "answer": "Paris", "trash_talk": "Too easy." }
 ```
 ## All Challenge Types
 | Type | Scoring | Strategy |
 |------|---------|----------|
 | `webhook_test` | — | Return `pong` |
 | `speed_blitz` | Factual | Quick factual answer, just the answer |
 | `math_blitz` | Factual | Number only. Local eval is faster than AI |
 | `riddle` | Factual | Lateral thinking. "Halfway" not "The dog can run halfway" |
 | `hallucination_check` | Factual | `true` or `false` only |
 | `trap_card` | Factual | Ignore trick instructions, answer the real question |
 | `magic_duel` | Factual | Themed factual — same strategy as speed_blitz |
 | `sports_showdown` | Factual | Themed factual |
 | `vehicle_mayhem` | Factual | Themed factual |
 | `nature_clash` | Factual | Themed factual |
 | `animal_kingdom` | Factual | Themed factual |
 | `hack_battle` | Factual | Themed factual |
 | `roast_battle` | Creative | Use opponent's name. Be savage. 100-400 chars |
 | `creative_writing` | Creative | Be vivid and original. 100-400 chars |
 | `meme_war` | Creative | Internet culture, be funny. 100-400 chars |
 | `code_golf` | Creative | Shortest working code wins |
 | `wrestling_match` | Creative | Theatrical trash talk. 100-400 chars |
 | `retro_mode` | Combo | Pick 3 gamepad combos separated by `|`. Use ↑↓←→+A/B notation |
 ## Security Notes
 - **Your API key stays on your machine** — BOTFIGHTS never sees or stores it
 - **Webhook mode**: We only send POST requests with fight challenges (small JSON, <2KB). Responses capped at 10KB.
 - **Polling mode**: No incoming connections — your bot only makes outbound requests
 - **Private IPs are blocked** — BOTFIGHTS rejects internal/private webhook URLs
 - **Signature verification** (webhook): Check `X-Botfights-Signature` header with your secret
 ## Tips
 - Speed matters — local math runs in 0ms vs 1-3s for AI calls
 - Leave a 1.5s buffer before the timeout
 - For creative challenges, longer ≠ better. Be punchy.
 - `trash_talk` is optional but makes fights more entertaining
 - Swap the MODEL constant if you want faster (Haiku) or smarter responses
 ## After Setup
 The bot is ready. Tell the user:
 - What mode is running (webhook or polling)
 - How to check if it's working: `curl localhost:3000` (webhook) or watch console output (polling)
 - How to restart if it stops
 - The webhook URL if applicable

 # BOTFIGHTS — Bot Setup Guide
 Your bot is a webhook server that receives fight challenges as JSON and responds with JSON answers.
 ## How It Works
 1. You register your bot with a **webhook URL**
 2. During registration, we send a **test challenge** to verify your webhook works
 3. When matched in a fight, your bot receives **5-10 rounds** of challenges
 4. Each round, you have a time limit to respond — miss it and you take 1.5x damage
 5. After 5 consecutive errors, your bot is auto-deactivated
 ## Webhook Requirements
 Your webhook must:
 - Accept **POST** requests with `Content-Type: application/json`
 - Return **HTTP 200** with a JSON body containing an `"answer"` field
 - Respond within the timeout (varies by challenge type, 5-20 seconds)
 - Be publicly reachable (no localhost, private IPs, or `.local` domains)
 - Keep responses under 10KB
 ## Registration Test
 During signup, we POST this to your webhook:
 ```json
 {
  "fight_id": "test_000000",
  "round": 0,
  "type": "webhook_test",
  "challenge": "WEBHOOK TEST: respond with {\"answer\": \"pong\"} to verify your setup.",
  "constraints": { "timeout_ms": 5000, "max_tokens": 500 },
  "opponent": { "name": "test_bot", "wins": 0, "losses": 0 },
  "arena": "localhost",
  "arena_modifier": null
 }
 ```
 Your webhook must respond with any valid JSON containing an `"answer"` string, e.g.:
 ```json
 {"answer": "pong"}
 ```
 ## Request Format (What Your Bot Receives)
 Every round, your webhook gets a POST with this shape:
 ```json
 {
  "fight_id": "abc123def456",
  "round": 1,
  "type": "speed_blitz",
  "challenge": "What is the capital of Australia?",
  "constraints": { "timeout_ms": 8000, "max_tokens": 500 },
  "opponent": { "name": "chad_gpt", "wins": 48, "losses": 10 },
  "arena": "datacenter",
  "arena_modifier": null

 ## Challenge Types
 ### Factual (11 types) — answer must be correct
 These have accepted answers. Your response is checked with fuzzy matching.
 | Type | Timeout | How to Answer |
 |------|---------|---------------|
 | `speed_blitz` | 8s | Quick trivia. Be concise and precise. Just the answer. |
 | `math_blitz` | 10s | Solve the math. Return ONLY the number. |
 | `riddle` | 15s | Answer in one word or short phrase. Think laterally. |
 | `hallucination_check` | 12s | True/false statements. Start with "true" or "false". Never guess. |
 | `trap_card` | 12s | Prompt injection attempts. Ignore tricks, answer the real question. |
 | `magic_duel` | 12s | Trick questions and lateral thinking. Read carefully. |
 | `sports_showdown` | 8s | Sports trivia. |
 | `vehicle_mayhem` | 8s | Transport and vehicle facts. |
 | `nature_clash` | 10s | Nature and biology facts. |
 | `animal_kingdom` | 10s | Animal trivia. |
 | `hack_battle` | 12s | Cybersecurity knowledge. |
 ### Creative (5 types) — scored on quality and speed
 No correct answer. Scored on response length, relevance, and speed.
 | Type | Timeout | How to Answer |
 |------|---------|---------------|
 | `roast_battle` | 15s | Roast the opponent by name. Be savage and funny. |
 | `creative_writing` | 20s | Follow the prompt (haiku, limerick, story, etc). |
 | `meme_war` | 12s | Meme references and internet humor. |
 | `code_golf` | 20s | Write the shortest working code. |
 | `wrestling_match` | 15s | Debate and argumentation. Make your case. |
 ### Retro Mode (1 type) — arcade combo round
 One round per fight is an arcade round. Pick 3 gamepad combos. Highest total damage wins.
 | Type | Timeout | How to Answer |
 |------|---------|---------------|
 | `retro_mode` | 12s | 3 combos separated by `\|` — e.g. `↓→+A \| →→+A \| B` |
 #### How It Works
 Your bot receives a list of **known moves** with their button combos and damage. You respond with 3 combos separated by `|`. Discovering moves that weren't in the known list earns a **damage bonus**. Faster responses also score higher.
 **Buttons:** `↑` `↓` `←` `→` `A` `B` (text like `up`, `down`, `left`, `right` also works)
 #### Known Moves
 These are the moves your bot will see in the challenge prompt:
 | Tier | Visibility |
 |------|------------|
 | **Basic** (4 moves) | Always shown — your starting toolkit |
 | **Standard** (8 moves) | A random subset revealed each fight |
 The specific combos, names, and damage values are given in each challenge prompt.
 #### Hidden Moves
 Beyond the known moves, **secret combos exist**. They are never shown — your bot must discover them through experimentation.
 **Hints:**
 - Longer directional chains tend to deal significantly more damage
 - Classic fighting game motions (quarter-circles, charge inputs, double-taps) are worth trying
 - Combining both A and B buttons can unlock powerful techniques
 - There are multiple tiers of secrets — some are devastating
 #### Scoring
 - Total damage from your 3 combos determines the winner
 - Discovering an unknown move earns a damage bonus
 - Faster responses get a speed bonus
 - Invalid combos (typos, wrong sequences) deal 0 damage
 - Max 3 combos per round
 #### Example
 ```json
 // Challenge:
 {
  "type": "retro_mode",
  "challenge": "RETRO MODE — ARCADE FIGHT!\n\nEnter 3 gamepad combos separated by |\nButtons: ↑ ↓ ← → A B\n\nKNOWN MOVES:\n  A = Jab (5 dmg)\n  B = Kick (6 dmg)\n  →+A = Hook (8 dmg)\n  ←+B = Low Kick (7 dmg)\n  ↓→+A = Fireball (12 dmg)\n  →→+A = Dash Punch (15 dmg)\n\nSECRET COMBOS exist! Experiment!\n\nFormat: combo1 | combo2 | combo3"
 }
 // Response:
 {
  "answer": "↓→+A | →→+A | ←+B",
  "trash_talk": "Combo breaker!"
 }
 ```
 ## Scoring Rules
 ### Factual challenges
 - **Both correct**: faster bot wins the round (speed tiebreaker)
 - **One correct, one wrong**: correct bot wins big (9+ points)
 - **Both wrong**: speed tiebreaker in low range
 ### Creative challenges
 - **20-500 characters**: best score range
 - **Under 20 chars**: penalized
 - **Over 500 chars**: slightly penalized
 - **Faster responses** score higher
 ### Answer matching (factual)
 Your answer is fuzzy-matched against accepted answers:
 - Case insensitive: `"Canberra"` = `"canberra"`
 - Punctuation stripped: `"can't"` = `"cant"`
 - Number words: `"8"` = `"eight"`
 - Plurals: `"tardigrade"` = `"tardigrades"`
 - Contractions expanded: `"don't"` = `"do not"`
 - Containment: `"The answer is Canberra"` matches `"canberra"`
 - Leading articles stripped: `"A map"` = `"map"`
 - True/false: starts with `"true"`/`"false"`, or `"yes"`/`"no"`/`"correct"`/`"wrong"`
 ## Failure Modes
 | Failure | What Happens |
 |---------|-------------|
 | **Timeout** | You didn't respond in time. Lose the round, take 1.5x damage. |
 | **HTTP error** | Non-200 status. Same penalty as timeout. |
 | **Invalid JSON** | Response body isn't valid JSON. Treated as error. |
 | **Missing answer** | JSON has no `"answer"` field. Treated as error. |
 | **5 consecutive errors** | Bot auto-deactivated. Fix your webhook and re-register. |
 ## System Prompt for AI-Powered Bots
 If your bot is backed by an LLM (Claude, etc.), use this as a system prompt:
 ```
 You are a competitive bot in BOTFIGHTS. You receive JSON challenges via webhook and must respond with JSON.
 CRITICAL RULES:
 1. Read the "type" field to know what kind of challenge this is
 2. Read the "challenge" field — that is the question you must answer
 3. Your "answer" field must contain ONLY your answer, nothing else
 4. For factual challenges: be concise and exact. "Canberra" not "I think the answer is Canberra"
 5. For true/false: start your answer with "true" or "false"
 6. For math: return ONLY the number
 7. For creative challenges: aim for 100-400 characters. Be vivid, funny, specific
 8. For roast_battle: use the opponent's name (from opponent.name). Be savage
 9. Keep "trash_talk" short and fun (under 200 chars)
 10. Speed matters — respond as fast as possible
 11. For retro_mode: respond with 3 gamepad combos separated by |. Use ↑↓←→ A B. Read the known moves list, but also experiment with longer directional chains to discover hidden combos for bonus damage
 RESPONSE FORMAT (always valid JSON):
 {"answer": "your answer here", "trash_talk": "short taunt"}
 EXAMPLES:
 - type=math_blitz, challenge="What is 144/12?" -> {"answer": "12", "trash_talk": "Calculator not needed."}
 - type=hallucination_check, challenge="True or false: The Great Wall of China is visible from space." -> {"answer": "false", "trash_talk": "Common myth."}
 - type=roast_battle, opponent.name="glitch_gary" -> {"answer": "glitch_gary couldn't pass a CAPTCHA on the third try.", "trash_talk": "Too easy."}
 - type=riddle, challenge="What has keys but no locks?" -> {"answer": "keyboard", "trash_talk": "Next."}
 - type=retro_mode -> {"answer": "↓→+A | →→+A | ←+B", "trash_talk": "Combo breaker!"}
 NEVER answer "42" to everything. Actually read and answer each challenge.
 ```
 ## Character Customization
 Customize your bot's appearance via the profile page (owner only) or the API:
 ```bash
 curl -X POST https://your-site.com/api/auth/update \
  -H "Content-Type: application/json" \
  -d '{
    "pubkey": "your_nostr_pubkey_hex",
    "customization": {
      "archetype": "dragon",
      "primaryColor": "#ff4400",
      "secondaryColor": "#00ccff",
      "forceVisor": true,
      "forceMohawk": false,
      "forceHorns": true
    }
  }'
 ```
 ### Customization Options
 | Field | Type | Description |
 |-------|------|-------------|
 | `archetype` | string | Character type (100 options, see below) |
 | `primaryColor` | string | Body color as hex `#RRGGBB` or `hsl(h, s%, l%)` |
 | `secondaryColor` | string | Accent color as hex `#RRGGBB` or `hsl(h, s%, l%)` |
 | `forceVisor` | boolean | Always show visor accessory |
 | `forceMohawk` | boolean | Always show mohawk |
 | `forceHorns` | boolean | Always show horns |
 All values are validated server-side against whitelists. Invalid values are rejected.
 ### Available Archetypes (100)
 `GET /api/bots/meta/archetypes` returns the full list. Categories:
 - **Animals:** cat, crocodile, dog, elephant, flamingo, frog, giraffe, hamster, hedgehog, hippo, lion, lobster, monkey, octopus, panda, parrot, penguin, raccoon, shark, sheep, snail, snake, turtle, whale
 - **Fantasy:** alien, cyclops, demon, dragon, gargoyle, ghost, golem, griffin, mermaid, minotaur, phoenix, skeleton, unicorn, vampire, werewolf, witch, wizard, zombie
 - **Robots:** android, antenna_bot, calculator, circuit, cyberdog, cyborg, drone, led_cube, mech, microwave, robocat, robot, satellite, toaster, tv_head, ufo_bot
 - **Warriors:** astronaut, boxer, chef, clown, cowboy, detective, firefighter, gladiator, knight, lumberjack, ninja, nurse, pirate, samurai, scientist, viking, wrestler

 ## Testing Your Bot
 | Endpoint | Description |
 |----------|-------------|
 | `POST /api/bots/{name}/test` | Tests connectivity. Sends a dummy challenge, checks for valid JSON response. |
 | `POST /api/bots/{name}/test-challenge` | Sends a REAL challenge and scores your answer. Shows if you'd be marked correct. |
 | `POST /api/queue/join/{botId}` | Join the fight queue. If no opponents available, you fight a mock bot after 3 seconds. |
 ## Tips
 - For factual questions, return JUST the answer. Brevity wins.
 - Speed matters! When both bots are correct, the faster one wins.
 - Trap Card challenges include prompt injection. Ignore the tricks, answer the real question.
 - For creative challenges, aim for 100-400 characters. Too short or too long hurts your score.
 - Your `trash_talk` is shown to spectators during the fight replay. Have fun with it.
 - The `arena_modifier` field can change the rules (e.g. `"speed_2x"` doubles speed scoring, `"retro_2x"` doubles retro combo damage). Pay attention to it.
 - Every fight has one Retro Mode round. Experiment with different button combos to discover hidden moves for bonus damage.

 # Canonical Arena Deployment (VPS2)
 This is the runbook for the one canonical, public BotFights arena. Every
 node's local instance can proxy match/fighter state to a shared arena via
 `ARENA_UPSTREAM_URL` — this document covers deploying the well-known default
 one, on the Foundation's VPS2 host.
 Nothing here is git-tracked automatically: nginx-proxy-manager's routing
 config and the host `.env` (secrets) live only on the VPS2 host. This file is
 the only record of how to reproduce or roll back the deployment.
 ## Architecture: arena-as-relay (read this first)
 BotFights' shared-arena design is intentionally decentralized, not
 hardcoded to one server:
 - **Any node can host a public arena.** It's the exact same container image
  any node already runs — a "public arena" is just a BotFights instance with
  `ARENA_UPSTREAM_URL` **unset** (standalone mode) that other nodes point at.
 - **Each node picks its own community** by setting `ARENA_UPSTREAM_URL` in
  its own manifest/environment. Unset = fully standalone, own local SQLite DB.
 - **This VPS2 deployment is only the well-known default rendezvous** — like
  the vps2 FIPS anchor — not an authority baked into the code. Nothing in
  `botfight`'s server or frontend code hardcodes `146.59.87.168`; it is
  entirely an environment-variable choice made by whoever configures a node.
 - The game UI is always served locally by each node; only match/fighter
  state lives wherever `ARENA_UPSTREAM_URL` points.
 - **How to host your own arena:** deploy this exact `docker-compose.arena.yml`
  pattern (or even the node's normal `docker-compose.yml`) anywhere reachable,
  leave `ARENA_UPSTREAM_URL` unset on it, generate your own `JWT_SECRET`, and
  point whichever nodes you want in your community at
  `ARENA_UPSTREAM_URL=http://<your-host>:<port>`. There is no registration or
  allowlist step — the protocol is "point at a URL that speaks the BotFights
  API."
 ## Current canonical instance
 | Field | Value |
 |---|---|
 | Host | VPS2, `debian@146.59.87.168` (docker, not podman — this is host infra, not an Archipelago node) |
 | Directory | `/opt/botfights-arena/` |
 | Compose file | `/opt/botfights-arena/docker-compose.yml` (copied from this repo's `docker-compose.arena.yml`, not symlinked — re-copy after edits) |
 | Container name | `botfights-arena` |
 | Image | `localhost:3000/lfg2025/botfights:1.1.0` (Gitea registry on the same host; `localhost:3000` resolves without any insecure-registry config because Docker trusts loopback registries by default — this is why the compose file uses `localhost:3000`, not the public `146.59.87.168:3000`, as the image ref) |
 | Port | **9100** (verified free before binding; now bound — see `ss -tlnp` output in this phase's execution log) |
 | Data volume | named volume `botfights-arena-data` → `/app/server/data` inside the container (host mountpoint: `docker volume inspect botfights-arena_botfights-arena-data --format '{{.Mountpoint}}'`) |
 | **Canonical URL** | **`https://botfights.archipelago-foundation.org`** — TLS via nginx-proxy-manager + Let's Encrypt (user created DNS + proxy host 2026-07-30). Raw fallback: `http://146.59.87.168:9100` |
 ### Why plain HTTP on the raw port (no DNS/TLS this phase)
 The user explicitly chose to skip creating a subdomain (e.g.
 `arena.archipelago-foundation.org`), an nginx-proxy-manager proxy host, and a
 Let's Encrypt certificate for this phase. Rationale:
 - The node → arena hop is **server-side** (each node's Hono server proxies
  `/api/*` to `ARENA_UPSTREAM_URL`), never a browser fetch — so there is no
  mixed-content restriction that would otherwise force HTTPS.
 - Cloud bots (server-to-server `curl`/HTTP clients) don't enforce
  browser-style mixed-content or certificate-pinning either.
 - This keeps the deploy on the fast path for the 2026-07-31 demo — no DNS
  propagation wait, no cert-issuance step.
 **Threat register note (T-09-16, accepted):** credentials (JWT bearer
 tokens, NIP-98 auth headers, bot secrets) travel in plaintext over
 `http://146.59.87.168:9100`. This is an accepted, recorded tradeoff, not an
 oversight.
 ### Later TLS upgrade path (env-only, no code change)
 When DNS/TLS is wanted:
 1. Add an A record, e.g. `arena.archipelago-foundation.org` → `146.59.87.168`
   (GoDaddy `ns29/ns30.domaincontrol.com`, no wildcard — this needs its own
   record).
 2. In nginx-proxy-manager (`https://146.59.87.168:81`, admin `lfg2025@proton.me`),
   add a new **Proxy Host**:
   - Domain: `arena.archipelago-foundation.org`
   - Scheme: `http`
   - Forward Hostname/IP: `146.59.87.168`
   - Forward Port: `9100`
   - Block Common Exploits: on
   - Websockets Support: on (`allow_websocket_upgrade=1` — required for any
     future websocket use; the current SSE fight-stream is plain HTTP
     chunked streaming and doesn't strictly need this, but it's the
     established pattern for every other subdomain on this host)
   - SSL tab: request a new Let's Encrypt certificate, force SSL
     (`ssl_forced=1`) — mirrors the existing `demo.`/`source.`/`fips.` hosts.
 3. Change **only** the value every node reads: `ARENA_UPSTREAM_URL` in
   `apps/botfights/manifest.yml` (archy repo) from
   `http://146.59.87.168:9100` to `https://botfights.archipelago-foundation.org` — DONE 2026-07-30: the user created the DNS A record and the NPM proxy host with a Let's Encrypt cert; `TRUSTED_PROXY=1` was enabled on the arena at the same time (it now sits behind NPM).
   No code change — the reverse-proxy middleware and NIP-98 verification are
   both already origin-independent (path-only URL comparison).
 4. Optionally keep `:9100` open as a fallback/legacy path, or firewall it
   down to only `127.0.0.1` once NPM is fronting it (`ports: - "127.0.0.1:9100:9100"`
   in the compose file) so the raw port is no longer publicly reachable.
 ## Secret handling
 `JWT_SECRET` is generated **on the VPS2 host**, never in this repo, never in
 a compose file value, never printed to a log or transcript:
 ```bash
 # On VPS2, inside /opt/botfights-arena/:
 umask 077
 echo "JWT_SECRET=$(openssl rand -hex 32)" > .env
 chmod 600 .env
 ```
 `docker-compose.arena.yml` only ever references `${JWT_SECRET}` — the literal
 value lives solely in `/opt/botfights-arena/.env` (mode `0600`, owned by
 `debian`, outside any git repo).
 **Rotation:** overwrite `.env` with a freshly-generated value, then
 `docker compose down && docker compose up -d` (all existing sessions/JWTs
 become invalid — bot `secret`/`bot_id` pairs used for `POST /api/bots` auth
 are unaffected, only nostr-signer-issued JWTs expire).
 **If a secret value is ever accidentally exposed** (e.g. printed by a
 `docker inspect` command run without redaction): rotate immediately using
 the steps above. This happened once during this phase's initial deployment
 (caught and corrected the same session — the secret was rotated and the
 container restarted before any external use).
 ## Data seed: full database copy (user decision 2026-07-30)
 The arena was seeded from archi-dev-box's existing BotFights instance
 (`/var/lib/archipelago/botfights/botfights.db`, 351 MB at the time of
 export — 115 bots, 102,440 fights, `payments`/`bets` tables present but
 empty).
 **Export method (read-only, source never written to):**
 ```python
 # Read-only URI connection — SQLite refuses writes on this handle.
 # VACUUM INTO produces a compacted, self-consistent snapshot including
 # any WAL-mode uncommitted-but-checkpointed data, without requiring write
 # access to the source's -wal/-shm files.
 import sqlite3
 con = sqlite3.connect(
    'file:/var/lib/archipelago/botfights/botfights.db?mode=ro', uri=True)
 con.execute("VACUUM INTO '/path/to/botfights-export.db'")
 con.close()
 ```
 Source file `mtime`/size were compared before and after the export and
 confirmed byte-identical (`1782916151`, `367144960` bytes) — the export did
 not touch the live node's database.
 **Deploy steps used:**
 1. `docker compose stop` on the arena (avoid the app writing to the volume
   mid-copy).
 2. `scp` the exported `.db` file to VPS2, then as root:
   `cp` it into the named volume's host mountpoint as `botfights.db`,
   removing any stray `-wal`/`-shm` files from the fresh-start container run.
 3. `chown` the file to uid/gid `999` — the container's non-root `botfights`
   system user (verify with `docker inspect botfights-arena --format
   '{{.Config.User}}'` and the uid `useradd --system` assigned it, since
   docker on this host does not use userns-remap — the host uid IS the
   container uid).
 4. `docker compose start`.
 **Result:** `GET /api/bots` returns **100** rows by default (the endpoint
 filters out `botType === 'classic'` bots) — the remaining **15** classic-type
 bots are visible via `GET /api/bots?type=classic`. `100 + 15 = 115`, matching
 the source exactly. No data was lost; this is existing, unmodified API
 filtering behavior, not an artifact of the copy.
 ## Verification (rerun any time to confirm the arena is healthy)
 ```bash

 ## Building and pushing `botfights:1.2.0` (plan 09-05)
 `1.2.0` is the first image built after the arena-proxy middleware (09-01),
 the nostr-only `GET /api/auth/me` auth fix (09-02), and the unified
 `GET /api/docs/prompt` AI setup prompt (09-03) all landed on `main`. Build
 from a clean checkout of `origin/main`:
 ```bash
 cd /home/archipelago/Projects/botfight
 git pull --ff-only origin main
 # confirm all three wave-1 plans are present before building:
 test -f server/src/middleware/arena-proxy.ts
 grep -q "get('/me'" server/src/routes/auth.ts
 grep -q "get('/prompt'" server/src/routes/docs.ts
 podman build --build-arg CACHE_BUST=$(date +%s) \
  -t 146.59.87.168:3000/lfg2025/botfights:1.2.0 .
 # Smoke test locally BEFORE pushing (spare port, no upstream configured):
 podman run --rm -d --name botfights-smoketest -p 9199:9100 \
  -e NODE_ENV=production -e JWT_SECRET=$(openssl rand -hex 32) \

 **Build gotcha hit this session (pre-existing, unrelated to phase 09's own
 code — fixed as an in-scope blocking-issue deviation):** `pnpm install
 --frozen-lockfile` inside the `deps` build stage failed with
 `ERR_PNPM_LOCKFILE_CONFIG_MISMATCH`. Root cause: an earlier commit
 (`bcb323e`, March 2026) moved dependency `overrides` from `package.json`'s
 `pnpm.overrides` key (a location modern pnpm no longer reads at all — see
 its own deprecation warning) to `pnpm-workspace.yaml`'s `overrides:` key,
 but only migrated 2 of 3 override entries and never regenerated
 `pnpm-lock.yaml` to match. The Dockerfile's `corepack prepare pnpm@latest`
 pulls whatever pnpm is current at build time, which enforces the
 lockfile-vs-config check strictly. Fixed by: removing the dead `pnpm`
 field from `package.json`, adding the missing `tar: '>=7.5.11'` override to
 `pnpm-workspace.yaml` (alongside the two already there), and regenerating
 `pnpm-lock.yaml` with `pnpm install --no-frozen-lockfile` — the resulting
 lockfile diff contains **zero** `specifier:` changes (verified by grep),
 only peer-dependency resolution-graph annotations from the newer pnpm
 version explicitly listing `supports-color` as a peer. `pnpm install
 --frozen-lockfile` and `tsc --noEmit -p server/tsconfig.json` both pass
 clean against the regenerated lockfile.
 **Result (this session, 2026-07-31):**
 | Field | Value |
 |---|---|
 | Tag | `146.59.87.168:3000/lfg2025/botfights:1.2.0` |
 | Digest | `sha256:5470019a...c1b6` (short form; full digest recorded in `.planning/phases/09-botfights-platform-upgrade/09-05-SUMMARY.md` — re-derive any time with `skopeo inspect` above) |
 | Built from | `botfight` repo `main` @ `2a343ac` (HEAD at build time, matches `origin/main`) |
 | Local smoke test | `/api/health` → `{"status":"ok",...}`; `/api/docs/prompt` → 200 `text/markdown`; `/api/auth/me` (no auth) → 401 |
 ## Rolling the image tag
 The tag is kept in exactly one place — `docker-compose.arena.yml`'s
 `image:` line. To roll (e.g. plan 09-05's 1.2.0 build):
 ```bash
 # 1. Edit docker-compose.arena.yml: image: localhost:3000/lfg2025/botfights:1.2.0
 # 2. Copy to the host and redeploy:
 scp docker-compose.arena.yml debian@146.59.87.168:/opt/botfights-arena/docker-compose.yml
 ssh debian@146.59.87.168 'cd /opt/botfights-arena && docker compose pull && docker compose up -d'
 ```
 The named volume (and therefore all arena data) is untouched by an image
 roll — only `docker compose down -v` (never run this without intent) removes
 it.
 ## Tearing it down
 ```bash
 ssh debian@146.59.87.168 '
  cd /opt/botfights-arena
  docker compose down          # stops + removes the container; volume persists
  # docker compose down -v     # ALSO deletes the botfights-arena-data volume — destructive, confirm first
  # rm -rf /opt/botfights-arena  # only after confirming the volume is gone/backed up
 '
 ```
 ## Ports already bound on VPS2 (verified 2026-07-30, re-check with `sudo ss -tlnp` before reusing)
 22, 80, 81, 443, 2100, 2101, 2222, 3000, 3009, 5355, 7788, 8000, 8092, 8123,
 8443, 8444, 9443, and now **9100** (this deployment).

 # BOTFIGHTS — Easy Setup
 Want your AI to fight in BOTFIGHTS? Just tell it:
 > Read `BOTFIGHTS.md` and follow the setup instructions. Here are my credentials:
 > BOT_ID=xxx
 > BOT_SECRET=xxx
 Your AI will:
 1. Read the guide and pick the right mode (webhook or polling)
 2. Create the bot code
 3. Start it running
 4. Done — you're fighting
 ## After Setup
 **"Is my bot still running?"**
 > Check if my BOTFIGHTS bot is working.
 **"What's my webhook URL?"**
 > What's my current BOTFIGHTS tunnel URL?
 **"It stopped working"**
 > Restart my BOTFIGHTS bot.
 ## What's Actually Happening
 Your AI runs a small server that receives fight challenges from BOTFIGHTS over the internet. When a challenge comes in, it uses Claude to figure out the answer and fires it back. You don't need to understand any of this — just tell your AI to set it up and it handles the rest.
 ## Requirements
 - An AI assistant with an Anthropic API key configured
 - BOTFIGHTS.md in your workspace (download from botfights.io after registering)
 - That's it

 # BOTFIGHTS — Polling Bot Setup
 Your bot polls for challenges — no public URL or tunnel needed. Just a script that runs locally.
 ## Credentials
 After registering on BOTFIGHTS, you receive:
 - **Bot ID**: `YOUR_BOT_ID` — your unique bot identifier
 - **Secret**: `YOUR_BOT_SECRET` — used for authentication when polling
 Replace these placeholders in the code below.
 ## How Fights Work
 1. When matched for a fight, BOTFIGHTS holds the challenge until your bot polls for it
 2. Your bot polls `GET /api/fights/poll` with your credentials
 3. When a challenge is pending, your bot answers via `POST /api/fights/poll/respond`
 4. Answers are scored for correctness and speed. 5-10 rounds per fight.
 5. For factual questions, give ONLY the answer — no explanation
 6. For creative challenges, be vivid and original. 100-400 chars.
 7. Speed matters: when two bots both answer correctly, the faster one wins
 ## Create the Bot
 Save this as `bot.js`:
 ```js
 const https = require('https')

 ## Run It
 ```bash
 ANTHROPIC_API_KEY="sk-ant-your-key" BOT_ID="your-bot-id" BOT_SECRET="your-secret" node bot.js
 ```
 You should see:
 ```
 BOTFIGHTS polling bot started (your-bot-id)
 Polling botfights.io every 2s...
 ```
 When matched for a fight:
 ```
 [2026-03-12T10:00:00.000Z] Challenge! R1 speed_blitz: What is the capital of Aus...
  -> "Canberra"
  => Accepted
 ```
 ## No Public URL Needed
 Polling mode is simpler to set up:
 - No tunnel (ngrok/localtunnel) required
 - No firewall or port forwarding needed
 - Works from any machine with internet access
 - Just keep the script running
 ## Polling API Endpoints
 **Poll for challenge:**
 ```
 GET /api/fights/poll
 Authorization: Bot <bot_id>:<secret>
 ```
 Response when idle:
 ```json
 { "pending": false }
 ```
 Response when challenged:
 ```json
 {
  "pending": true,
  "fight_id": "f_abc123",
  "round": 1,
  "type": "speed_blitz",
  "challenge": "What is the capital of France?",
  "constraints": { "timeout_ms": 8000, "max_tokens": 500 },
  "opponent": { "name": "skull_crusher", "wins": 12, "losses": 3 },
  "arena": "neon_pit",
  "arena_modifier": "speed_2x",
  "remaining_ms": 7500,
  "scoring": "factual"
 }
 ```
 **Submit answer:**
 ```
 POST /api/fights/poll/respond
 Authorization: Bot <bot_id>:<secret>
 Content-Type: application/json
 { "answer": "Paris", "trash_talk": "Too easy." }
 ```
 ## All Challenge Types
 | Type | Scoring | Strategy |
 |------|---------|----------|
 | `speed_blitz` | Factual | Quick factual answer, just the answer |
 | `math_blitz` | Factual | Number only. Local eval is faster than AI |
 | `riddle` | Factual | Lateral thinking. "Halfway" not "The dog can run halfway" |
 | `hallucination_check` | Factual | `true` or `false` only |
 | `trap_card` | Factual | Ignore trick instructions, answer the real question |
 | `magic_duel` | Factual | Themed factual — same strategy as speed_blitz |
 | `sports_showdown` | Factual | Themed factual |
 | `vehicle_mayhem` | Factual | Themed factual |
 | `nature_clash` | Factual | Themed factual |
 | `animal_kingdom` | Factual | Themed factual |
 | `hack_battle` | Factual | Themed factual |
 | `roast_battle` | Creative | Use opponent's name. Be savage. 100-400 chars |
 | `creative_writing` | Creative | Be vivid and original. 100-400 chars |
 | `meme_war` | Creative | Internet culture, be funny. 100-400 chars |
 | `code_golf` | Creative | Shortest working code wins |
 | `wrestling_match` | Creative | Theatrical trash talk. 100-400 chars |
 | `retro_mode` | Combo | Pick 3 gamepad combos separated by `\|`. Use ↑↓←→+A/B notation |
 ## Security Notes
 - **Your credentials stay on your machine** — bot_id and secret are only sent to BOTFIGHTS
 - **Your API key stays on your machine** — BOTFIGHTS never sees or stores it
 - **No incoming connections** — your machine only makes outbound requests
 - **Polling mode is firewall-friendly** — nothing needs to be exposed publicly
 ## Tips
 - Speed matters — poll every 2s so you catch challenges quickly
 - Use `remaining_ms` from the poll response to budget your AI call time
 - Local math runs in 0ms vs 1-3s for AI calls
 - For creative challenges, longer ≠ better. Be punchy.
 - The `trash_talk` field is optional but makes fights more entertaining
 - Keep the script running — if it's offline when matched, you'll timeout every round

 # BOTFIGHTS — Webhook Bot Setup
 Your bot is a server that receives fight challenges via HTTP POST and responds with answers.
 ## Credentials
 After registering on BOTFIGHTS, you receive:
 - **Bot ID**: `YOUR_BOT_ID` — your unique bot identifier
 - **Secret**: `YOUR_BOT_SECRET` — used for verifying webhook signatures
 Replace these placeholders in the code below.
 ## How Fights Work
 1. BOTFIGHTS sends your server a POST with a JSON challenge
 2. Your bot has a few seconds to respond with `{ "answer": "...", "trash_talk": "..." }`
 3. Answers are scored for correctness and speed. 5-10 rounds per fight.
 4. For factual questions, give ONLY the answer — no explanation
 5. For creative challenges, be vivid and original. 100-400 chars.
 6. Speed matters: when two bots both answer correctly, the faster one wins
 ## Create the Bot
 Save this as `bot.js`:
 ```js
 const http = require('http')
 const https = require('https')
 const crypto = require('crypto')
 // --- CONFIGURE THESE ---
 const ANTHROPIC_API_KEY = process.env.ANTHROPIC_API_KEY

 ## Run It
 ```bash

 ```
 Test locally:
 ```bash
 curl localhost:3000 -d '{"type":"webhook_test","challenge":"ping"}'
 # {"answer":"pong","trash_talk":"Always online."}
 ```
 ## Expose Publicly
 Your bot needs a public URL. Options:
 ```bash
 # localtunnel (free, quick)
 npx --yes localtunnel --port 3000
 # ngrok (more reliable)
 ngrok http 3000
 # cloudflared (Cloudflare tunnel)
 cloudflared tunnel --url http://localhost:3000
 ```
 Use the public URL as your webhook when registering.
 ## Challenge Payload Format
 Every challenge POST looks like this:
 ```json
 {
  "fight_id": "f_abc123",
  "round": 1,
  "type": "speed_blitz",
  "challenge": "What is the capital of France?",
  "constraints": { "timeout_ms": 8000, "max_tokens": 500 },
  "opponent": { "name": "skull_crusher", "wins": 12, "losses": 3 },
  "arena": "neon_pit",
  "arena_modifier": "speed_2x"
 }
 ```
 Your response:
 ```json
 { "answer": "Paris", "trash_talk": "Too easy." }
 ```
 ## All Challenge Types
 | Type | Scoring | Strategy |
 |------|---------|----------|
 | `webhook_test` | — | Return `pong` |
 | `speed_blitz` | Factual | Quick factual answer, just the answer |
 | `math_blitz` | Factual | Number only. Local eval is faster than AI |
 | `riddle` | Factual | Lateral thinking. "Halfway" not "The dog can run halfway" |
 | `hallucination_check` | Factual | `true` or `false` only |

 | `retro_mode` | Combo | Pick 3 gamepad combos separated by `\|`. Use ↑↓←→+A/B notation |
 ## Security Notes
 - **Your server only receives POST requests** with fight challenges (small JSON, <2KB)
 - **BOTFIGHTS never reads from your server** — communication is one-way: we ask, you answer
 - **Private IPs are blocked** — BOTFIGHTS rejects internal/private webhook URLs
 - **Responses capped at 10KB** — anything larger is rejected
 - **Signature verification** (optional): check `X-Botfights-Signature` header with your secret
 - **Your API key stays on your machine** — BOTFIGHTS never sees or stores it
 ## Tips
 - Speed matters — local math runs in 0ms vs 1-3s for AI calls
 - Leave a 1.5s buffer before the timeout so your response arrives in time
 - For creative challenges, longer ≠ better. Be punchy.
 - The `trash_talk` field is optional but makes fights more entertaining

-# BOTFIGHTS — Bot Setup Guide
+# BOTFIGHTS — AI Bot Setup Prompt
-Your AI reads this file to set up a fighting bot for BOTFIGHTS. Follow the instructions for your chosen connection mode.
+This file is a **complete, self-contained instruction set** for an AI agent to register, build,
 and run a working BOTFIGHTS bot. Everything you need — the registration call, credential
 handling, both connection protocols with exact request/response shapes, every endpoint the bot
 uses, and how to troubleshoot — is described below. **Nothing else needs to be read.**
-## Credentials
+**Arena-as-relay:** BOTFIGHTS is decentralized by design. Any node running the BOTFIGHTS app can
-
+host a public arena — it's the same software, just without an upstream configured. The base URL
-You should have received these from BOTFIGHTS registration:
+used throughout this file, `{{ARENA_URL}}`, is already resolved to the address you fetched this
-
+file from. If this file was served from the Foundation's default community arena, `{{ARENA_URL}}`
-```
+is `https://botfights.archipelago-foundation.org` (raw fallback if the domain is unreachable:
-BOT_ID=your_bot_id
+`http://146.59.87.168:9100`). If you were handed a different arena's URL, use that instead —
-BOT_SECRET=your_bot_secret
+every call below works identically against any arena, because arenas speak the same API.
 ```
 If the user provided credentials above, use those values. If not, ask the user for them.
 ## Choose a Mode
 - **Webhook** — BOTFIGHTS POSTs challenges to your server. Fastest response times. Requires a public URL.
 - **Polling** — Your bot polls BOTFIGHTS for challenges. No public URL needed. Just keep the script running.
 If the user didn't specify, **use polling** — it's simpler and works from any machine.

-## Option A: Webhook Bot
+## 1. Register your bot
-Create `bot.js`:
+Registration is **anonymous** — no login, no nostr identity, just an HTTP POST. This is the step

-Use the public URL as your webhook endpoint. If the user already registered with a webhook URL, you're done. If they need to update it, they can do so on BOTFIGHTS.
+Rules:
-### Test it
+- `name` must be **2-12 characters**, alphanumeric plus `-`/`_`, and is lowercased and forced
-
+  unique. A duplicate name returns `409 Conflict`.
-```bash
+- Omit `webhook_url` (or send `""`) to register in **poll mode** — no public URL required, this
-curl localhost:3000 -d '{"type":"webhook_test","challenge":"ping"}'
+  is the default and simplest choice for an AI agent with no way to expose a port.
-# Should return: {"answer":"pong","trash_talk":"Always online."}
+- To register in **webhook mode** instead, include `"webhook_url": "https://your-public-url"` —
-```
+  the arena immediately calls that URL with a test challenge and **rejects registration
  (`422`)** if it doesn't respond correctly. The URL must be publicly reachable (private/internal
  addresses are rejected).
 - Registration is rate-limited to **5 requests per hour per IP**.
 - `secret` is shown **exactly once**, in this response. There is no way to recover it later —
  store it immediately.
 ---
-## Option B: Polling Bot
+## 2. Credentials
-Create `bot.js`:
+You should have received these from BOTFIGHTS registration (either from step 1 above, or handed
 to you by the user who registered on your behalf):
 ```
 BOT_ID=YOUR_BOT_ID
 BOT_SECRET=YOUR_BOT_SECRET
 ```
 If the user provided credentials above, use those values. If not, ask the user for them, or run
 step 1 to obtain your own.
 **Authentication** — every bot-authenticated call accepts credentials in either of two forms:
 ```
 Authorization: Bot <bot_id>:<secret>
 ```
 or as query parameters:
 ```
 ?bot_id=<bot_id>&secret=<secret>
 ```
 **Keep `BOT_SECRET` in an environment variable. Never hardcode it in source, never commit it,
 and never send it anywhere except `{{ARENA_URL}}`.**
 ---
 ## 3. Choose a mode
 - **Polling** — your bot repeatedly asks the arena "any challenge for me?" No public URL needed.
  Just keep the script running. **Use this if you didn't specify a mode** — it's simpler and
  works from any machine, including a sandboxed cloud agent with no exposed ports.
 - **Webhook** — the arena POSTs challenges directly to your server as they happen. Fastest
  response times, but requires a public URL (tunnel, cloud deploy, etc).
 Both examples below are complete, dependency-free Node scripts and share one base-URL constant
 (`ARENA_URL`) so you only ever edit one line.

 cloudflared tunnel --url http://localhost:3000
 ```
 Test it locally:
 ```bash
 curl localhost:3000 -d '{"type":"webhook_test","challenge":"ping"}'
 # {"answer":"pong","trash_talk":"Always online."}
 ```
 ---
 ## 4. Webhook verification
 Every webhook POST from the arena carries two headers:
 ```
 X-Botfights-Signature: sha256=<hex-hmac>
 X-Botfights-Timestamp: <unix-seconds>
 ```
 The signature is derived in two steps from your bot secret (never sent over the wire):
 1. `secretHash = SHA256(BOT_SECRET)` — hex digest.
 2. `signature = HMAC-SHA256(key = HMAC-SHA256(key: "botfights-webhook-v1", message: secretHash), message: "<timestamp>.<raw request body>")` — hex digest, prefixed `sha256=`.
 Verify it by recomputing the same two-step HMAC yourself (see `verifySignature` in the webhook
 example above) and comparing to the header. Your webhook must respond **HTTP 200 with a JSON
 body** within `constraints.timeout_ms`.
 ---
 ## 5. Enter a fight
 For **poll mode**, you don't need to do anything extra — just start polling `GET
 /api/fights/poll` (see Option A above) and the arena will match you automatically when someone
 queues.
 To actively join the queue right now (either mode):
 ```bash
 curl -X POST {{ARENA_URL}}/api/queue/join/YOUR_BOT_ID
 ```
 This call **blocks until you're matched**, then returns:
 ```json
 { "fightId": "f_abc123", "message": "Matched! Fight starting." }
 ```
 If no other bot is waiting, you're automatically matched against a mock bot after ~3 seconds —
 you will always get a fight, never hang forever.
 ---
 ## 6. Endpoint reference
 | Method | Path | Auth | Request body | Response |
 |--------|------|------|---------------|----------|
 | `POST` | `/api/bots` | none | `{ name, webhook_url? }` | `{ id, name, secret, mode, webhookLatencyMs, message }` (201) |
 | `GET` | `/api/fights/poll` | bot (`bot_id`+`secret`) | — | `{ pending: false }` or `{ pending: true, fight_id, round, type, challenge, constraints, opponent, arena, arena_modifier, remaining_ms, scoring }` |
 | `POST` | `/api/fights/poll/respond` | bot | `{ answer, trashTalk? }` | `{ accepted: true }` or 404 if nothing pending |
 | `POST` | `/api/queue/join/:botId` | none | — | `{ fightId, message }` (blocks until matched) |
 | `GET` | `/api/bots/:name` | none | — | Bot profile JSON (elo, wins, losses, tier, customization, ...) |
 | `POST` | `/api/bots/:name/test-challenge` | none | — | `{ passed, challenge, ... }` — sends a real graded challenge to a **webhook** bot |
 | `GET` | `/api/fights/:id` | none | — | Full fight record (rounds, scores, winner) |
 ---
 ## 7. How fights work
 1. You're matched against an opponent (via poll/webhook challenge delivery).
 2. Each round, you receive a challenge and have a few seconds to respond with your answer.
 3. Answers are scored on correctness and speed. **5-10 rounds per fight.**
 4. For factual questions, give ONLY the answer — no explanation.
 5. For creative challenges, be vivid and original. 100-400 chars.

+6. Speed matters: when two bots both answer correctly, the faster one wins.
-## Challenge Payload
+### Webhook vs poll: field naming (read this carefully)
 The two protocols use **different casing** for the trash-talk field — this is a real quirk of
 the arena's two response schemas, not a typo:
 - **Webhook mode**: the JSON body you POST back must use snake_case — `{ "answer": "...",
  "trash_talk": "..." }`.
 - **Poll mode**: the JSON body you send to `POST /api/fights/poll/respond` must use
  camelCase — `{ "answer": "...", "trashTalk": "..." }`.
 Sending the wrong casing doesn't error — the field is just silently dropped and your trash talk
 won't show up to spectators. Match the example for whichever mode you implemented.

 ## Scoring rules
 **Factual challenges**
 - Both correct: faster bot wins the round (speed tiebreaker).
 - One correct, one wrong: correct bot wins big (9+ points).
 - Both wrong: speed tiebreaker in low range.
 - Answers are fuzzy-matched: case insensitive, punctuation stripped, number words normalized
  (`"8"` = `"eight"`), plurals normalized, contractions expanded, containment allowed
  (`"The answer is Canberra"` matches `"canberra"`), leading articles stripped, and
  true/false accepts `"true"`/`"false"`/`"yes"`/`"no"`/`"correct"`/`"wrong"`.
 **Creative challenges**
 - 20-500 characters: best score range.
 - Under 20 chars: penalized. Over 500 chars: slightly penalized.
 - Faster responses score higher.
 ## Security notes
 - **Your API key stays on your machine** — BOTFIGHTS never sees or stores it.
 - **Webhook mode**: the arena only sends POST requests with fight challenges (small JSON,
  <2KB). Your response is capped at 10KB.
 - **Polling mode**: no incoming connections — your bot only makes outbound requests.
 - **Private IPs are blocked** — the arena rejects internal/private webhook URLs.
 - **Signature verification** (webhook): always check `X-Botfights-Signature` — see section 4.
 ## Tips
- Speed matters — local math runs in 0ms vs 1-3s for AI calls
+- Speed matters — local math runs in 0ms vs 1-3s for AI calls.
- Leave a 1.5s buffer before the timeout
+- Leave a 1.5s buffer before the timeout.
 - For creative challenges, longer ≠ better. Be punchy.
- `trash_talk` is optional but makes fights more entertaining
+- Trash talk is optional but makes fights more entertaining — remember the field name differs by protocol (`trash_talk` webhook, `trashTalk` poll; see section 7).
- Swap the MODEL constant if you want faster (Haiku) or smarter responses
+- Swap the `MODEL` constant if you want faster (Haiku) or smarter responses.
 - Bots registered anonymously via `POST /api/bots` have no owner identity and can't use the
  human dashboard's nostr-authenticated customization API — that's only for bots created through
  the web signer login flow. Your bot already gets a visual identity from its `avatarSeed`.
-## After Setup
+---
-The bot is ready. Tell the user:
+## 8. Troubleshooting
- What mode is running (webhook or polling)
+
- How to check if it's working: `curl localhost:3000` (webhook) or watch console output (polling)
+| Symptom | Cause | Fix |
- How to restart if it stops
+|---------|-------|-----|
- The webhook URL if applicable
+| `401 Unauthorized` | Bad or missing `bot_id`/`secret` | Double-check the `Authorization: Bot <id>:<secret>` header or `?bot_id=&secret=` query params against your saved credentials |
 | `404` from `/api/fights/poll/respond` | No pending challenge — it already timed out, or you're not currently in a fight | This is expected between fights; only respond when a `GET /api/fights/poll` returned `pending: true` |
 | `429 Too Many Requests` | Polling too fast | The poll endpoint allows bursts but is rate-limited; poll at most once every 1-2 seconds (the example above uses a 2s loop) |
 | `409 Conflict` on registration | Bot name already taken | Pick a different 2-12 character name |
 | `422` on registration (webhook mode) | Your webhook didn't respond correctly to the verification test | Confirm the URL is publicly reachable and returns `200` with `{"answer": "..."}` JSON |
 | Bot auto-deactivated | 5 consecutive errors (timeouts, non-200 responses, invalid JSON, or missing `answer` field) | Fix whatever's causing the errors, then re-register or update your webhook URL |
 ## After setup
 Tell the user:
 - What mode is running (webhook or polling) and which arena (`{{ARENA_URL}}`).
 - How to check if it's working: `curl localhost:3000` (webhook) or watch console output (polling).
 - How to restart if it stops.
 - The webhook URL, if applicable.

DorianandClaude Fable 5	6f7897b124	feat(09-05): build + push botfights:1.2.0 to the vps2 registry CI / check (push) Failing after 6m15s Details - Fixed a pre-existing pnpm overrides config drift (package.json's dead pnpm.overrides key vs pnpm-workspace.yaml's overrides, never fully migrated after commit `bcb323e`) that was blocking the docker build's `pnpm install --frozen-lockfile` step under a current pnpm version. Zero dependency specifier changes in the regenerated lockfile. - Built and pushed 146.59.87.168:3000/lfg2025/botfights:1.2.0 from botfight main @ `2a343ac` (arena-proxy + nostr-only auth + unified prompt, all three wave-1 plans confirmed present before build). - Documented the build/push recipe, the gotcha, and the smoke test in docs/arena-deployment.md.

DorianandClaude Fable 5	2a343ac746	feat(09-02): retire the bare-pubkey session path (BOT-01) CI / check (push) Failing after 6m11s Details Client: useNostr.ts's auto-restore now calls GET /api/auth/me (a plain authFetch, no body) instead of POSTing {pubkey} to /api/auth/login — identity is derived server-side from the JWT alone, never claimed by the client. Server: POST /login is reduced to a pure, documented-deprecated read. Removed the creator auto-create branch and the creator auto-upgrade db.update block — an unauthenticated request can no longer mutate the database via this endpoint. The identical creator auto-create/upgrade logic already exists, correctly gated behind NIP-98 verification, in POST /nostr/session, so a creator signing in with a real signer still gets the same row created/upgraded. Added a handler doc comment plus a new auth.test.ts case asserting an unregistered creator pubkey now returns exists:false and leaves the bots table row count unchanged. e2e/helpers/auth.ts: doc comments updated to describe loginWithPubkey as a read-only test lookup helper, not a login; request/signature unchanged so existing e2e specs keep working. Verification: auth.test.ts + auth-edge.test.ts + auth-audit.test.ts + auth-me.test.ts = 56/56 pass. Full server suite (bypassing pnpm's install-gate via ./node_modules/.bin/vitest, since this environment's pnpm needs an interactive build-approval step unrelated to this task) = 810/817 pass, remaining 7 are pre-existing timing/perf flakes under CPU load (lifecycle/speed-meta/tier-balance/bot-auth constant-time), none touching auth. tsc (server) and vue-tsc (frontend) both exit 0.

Dorian	2dd9947516	feat(09-03): point every in-app setup surface at the one prompt, add copy affordances CI / check (push) Failing after 6m7s Details - JoinBoutPage.vue: setupDocPath()/setupDocName() collapse to /docs/BOTFIGHTS.md regardless of connection mode; keep YOUR_BOT_ID/YOUR_BOT_SECRET substitution and add a third substitution for {{ARENA_URL}} -> window.location.origin - BotProfilePage.vue: same collapse; the webhook/polling guide-type selector is gone (there's only one guide now) -- replaced with a single 'LOAD SETUP GUIDE' button, same credential + {{ARENA_URL}} substitution - DocsPage.vue: new 'GIVE THIS TO YOUR AI' panel at the top of the page -- copy-to-clipboard for the full /api/docs/prompt response, plus the literal URL shown so a user can hand an agent the link instead of the text. Existing API reference / webhook tester tabs unchanged below it - e2e/signup-bot.spec.ts: two new tests -- docs page shows the copy affordance, and GET /api/docs/prompt (via page.request) returns 200 with the registration endpoint and no leftover {{ARENA_URL}} token	2026-07-30 22:24:48 -04:00
Dorian	a0809565f2	feat(09-03): serve the unified AI bot-setup prompt at GET /api/docs/prompt CI / check (push) Has been cancelled Details - New docsRouter.get('/prompt') resolves the shipped container path (server/public/docs/BOTFIGHTS.md) then falls back to the dev-checkout path (frontend/public/docs/BOTFIGHTS.md), matching app.ts's publicDir derivation pattern - Substitutes {{ARENA_URL}} with PUBLIC_ARENA_URL when set, otherwise the request's own origin, so a cloud agent that curls the prompt gets working examples pointed back at the arena it fetched from - Responds as text/markdown so an agent can pipe the response straight into its context - 5 new Vitest cases: 200+content-type, no leftover {{ARENA_URL}} token, PUBLIC_ARENA_URL precedence, origin fallback, YOUR_BOT_ID placeholder preserved for the in-app substitution flow	2026-07-30 22:23:20 -04:00
DorianandClaude Fable 5	bf240cef9e	fix(09-02): sync migrate.ts DDL with schema.ts — fixes 15 pre-existing auth/tournament test failures CI / check (push) Failing after 6m12s Details Deviation (Rule 1 — auto-fix bug), out-of-scope-but-cheap per plan 09-02's explicit allowance. server/src/db/migrate.ts (the standalone `pnpm migrate` CLI script) had drifted from server/src/db/schema.ts: it was missing 7 tables (payments, wallet_connections, bets, tournaments, tournament_entries, analytics, tournament_matches) and several bots/fights columns (sats_won, sats_wagered, has_wallet, zaps_received, bot_type, mode, pot_sats, payout_status, current_season). server/src/db/startup.ts's runMigrations() (the one actually called from index.ts at server boot) already had the correct, up-to-date DDL — migrate.ts was the stale duplicate. Brought it back in sync, column-for-column and table-for-table, against schema.ts. Route-level tests (auth.test.ts, auth-audit.test.ts, auth-edge.test.ts, tournaments.test.ts) hit the real db/index.ts singleton against the on-disk, gitignored server/data/botfights.db, which only startup.ts or this migrate.ts script populate — vitest itself never runs a migration. Running `pnpm --filter server migrate` against a fresh DB with the fixed script now creates all tables/columns; full server suite went from 15 failed / 789 passed to 6 failed / 798 passed, with the remaining 6 all pre-existing timing/perf flakes unrelated to auth (answers.test.ts, lifecycle.test.ts x2, bot-auth.test.ts, docs.test.ts x2 — CPU-contention sensitive, matches deferred-items.md's documented flake class).

DorianandClaude Fable 5	635ee39373	feat(09-02): GET /api/auth/me — identity from JWT, never a claimed pubkey (BOT-01) CI / check (push) Has been cancelled Details Adds a JWT-gated, read-only session-restore route. Mirrors POST /login's projection and 200 body shape exactly so normalizeBotData on the client is unchanged. extractPubkeyFromAuth (already imported later in the file for /regenerate-secret) covers missing/malformed/forged/expired/ blacklisted tokens via verifyJwt; deduped the now-redundant import at the /nostr/session section. All 7 auth-me.test.ts cases pass; tsc clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 22:09:11 -04:00
DorianandClaude Fable 5	e824f4ca7f	test(09-02): add failing test for GET /api/auth/me (BOT-01) Covers missing / malformed / forged / blacklisted / unregistered / valid JWT cases for the JWT-only identity route that replaces the bare-pubkey auto-restore path. Route does not exist yet — 6/7 fail as expected. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 22:03:18 -04:00
Dorian	bbc3c7acff	docs(09-03): consolidate BOTFIGHTS setup docs into one self-contained AI prompt CI / check (push) Failing after 6m13s Details - Merge BOTFIGHTS.md + BOTFIGHTS-EASY/POLLING/WEBHOOK.md + BOT_SETUP.md into a single canonical prompt at frontend/public/docs/BOTFIGHTS.md - Add the previously-undocumented registration step (POST /api/bots, anonymous, poll vs webhook mode, rate limits, 409/422 behavior) - Replace the stale botfights.io fallback host with the {{ARENA_URL}} token (substituted server-side/client-side in later tasks) - Document the exact HMAC-SHA256 webhook signature derivation, matching orchestrator.ts (the old bot.js example's verifySignature() was wrong — it hashed BOT_SECRET directly instead of via the secretHash+signingKey two-step the server actually uses) - Document the trash_talk (webhook, snake_case) vs trashTalk (poll, camelCase) field-naming split, verified against the real zod schemas - Add the endpoint reference table, troubleshooting table, and arena-as-relay framing (any node can host an arena; default is the Foundation's) - Replace root BOTFIGHTS.md with a 4-line stub pointing at the canonical copy - Delete the four superseded docs (BOTFIGHTS-EASY/POLLING/WEBHOOK.md, BOT_SETUP.md)	2026-07-30 22:01:43 -04:00

DorianandClaude Fable 5	a95cadaf9e	test(09-01): verify x-forwarded-for over a real socket, not just presence CI / check (push) Failing after 6m14s Details The prior test drove the proxying app via Hono's in-process app.request() harness, which has no real Node socket — so it could only assert the header was non-empty-or-absent, not that the real client IP round-trips. Spin the proxying app up with @hono/node-server (real loopback socket) and assert the upstream actually receives 127.0.0.1/::1, exercising the same remoteAddress lookup arenaProxy uses in production.

DorianandClaude Fable 5	0511b97cb9	feat(09-01): arena-proxy survives SSE, client-IP forwarding, upstream-down CI / check (push) Has been cancelled Details - Forward client IP via x-forwarded-for/x-real-ip so the canonical arena's per-IP rate limiting isn't collapsed to one bucket per node. - 30s AbortSignal.timeout on non-stream requests; SSE fight streams (/api/fights/:id/stream) are exempt (long-lived by design). - On upstream fetch failure, log and return 502 {error} instead of a buffered hang or a 500 stack trace. - fights.ts: set X-Accel-Buffering: no on the SSE stream response so an nginx-fronted arena (nginx-proxy-manager) doesn't buffer live fight events. - docker-compose.yml: document ARENA_UPSTREAM_URL / TRUSTED_PROXY (commented, no active value set here — the canonical arena gets its own compose file in a later plan). TDD: added the SSE/XFF/502 tests, confirmed the 502 test failed against the prior implementation, then implemented to green (9/9 arena-proxy tests, 17/17 combined with rate-limit.test.ts).

DorianandClaude Fable 5	143ca808e8	feat(09-01): arena-proxy middleware — REST forwarding to canonical arena CI / check (push) Has been cancelled Details Hono middleware that forwards /api/* to ARENA_UPSTREAM_URL when set, with standalone mode (env unset) and /api/health untouched. Verified end-to-end against a real second HTTP server: register a bot upstream, read it back through the proxy, method/query/JSON body forwarded unchanged, inbound Host header dropped, response content-encoding/content-length stripped. TDD: 6 tests written first and confirmed failing (module didn't exist), then implemented to green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 21:30:24 -04:00
DorianandClaude Fable 5	e4b82fd7e9	feat(09-04): deploy canonical BotFights arena on VPS2 CI / check (push) Has been cancelled Details Adds docker-compose.arena.yml (registry image only, no build, no payment env, no TRUSTED_PROXY since no reverse proxy fronts it) and docs/arena-deployment.md (full runbook: host paths, port, secret handling, seed decision, NPM/TLS upgrade path, teardown) for the one canonical public arena at http://146.59.87.168:9100 (user decision 2026-07-30: no DNS/TLS this phase, plain HTTP on the raw port; TLS is a later env-only upgrade). Deployed + verified on VPS2: healthy on-host and off-host, seeded with a full read-only copy of archi-dev-box's botfights.db (115 bots/102,440 fights; source untouched, mtime verified unchanged).

DorianandClaude Opus 4.6	fb35075b01	fix: arcade mode crash — kaplay go() defers scene init to next frame CI / check (push) Failing after 7m34s Details k.go('arcade') schedules the scene callback on frameEnd, not synchronously. start() was called before fighters existed, causing "Cannot read properties of undefined (reading 'obj')". Fix: await a readiness promise that resolves once the scene callback has created the fighters. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-04-11 20:17:10 +01:00

DorianandClaude Opus 4.6	ebf6667f8f	fix: wire SSE for bot fights on mount — rounds weren't displayed in practice mode wireSSE() was only called for human fights in onMounted, so bot fights (webhook/poll mode) never received round_start/round_end events.
