$\"Discord$

\n\n---\n\n## What you get\n\n- **A branded portal per server** (`/g/{guildId}`) — CAPTCHA → \"Continue with\n Discord\" → done. Each server's logo, colors, name, and copy are its own.\n- **Multi-tenant from one val** — per-server config (role, branding, channels,\n alert tuning, optional Turnstile keys) lives in SQLite, keyed by guild id.\n- **A guarded admin API** (`/admin/guilds`) — add, edit, and remove servers at\n runtime with a bearer token. No redeploy.\n- **One shared Discord app + bot** — a single OAuth app with **one** registered\n `/callback` redirect URI serves unlimited servers (the guild is carried in the\n one-time state nonce, not the URL).\n- **One-time, single-use state nonces** (SQLite) bound to a passed CAPTCHA *and*\n a specific server, so a callback can't be replayed, forged, or cross-wired.\n- **Automatic role grant** via the bot using only the `identify` OAuth scope (the\n shield never sees a password and never reads message content).\n- **Per-server raid alerts** — a Discord webhook ping when an abnormal number of\n *successful* verifications land in a short window, counted and debounced per\n server (the farmed-account pattern Turnstile can't catch).\n- **A dynamic social card per server** (`/g/{guildId}/og.png`) rendered with\n satori + resvg and cached.\n- **Per-server DMZ bootstrap** (`setup.ts`) — the bot creates the `#about`,\n `#rules`, `#verify`, and `#do-not-post` channels (read-only, honeypot open)\n and posts every message into them.\n- **Editable messages** — re-running a post tool updates the existing message in\n place instead of duplicating it (channel + message IDs are kept in blob,\n namespaced per guild).\n- **An audit log** of every attempt (per server), auto-pruned after 7 days.\n\n## How it works\n\n```\nVisitor Portal (this val) Discord\n │ GET /g/{id} ───────────▶ load server config + theme (SQLite)\n │ render CAPTCHA page\n │ solve Turnstile\n │ POST /g/{id}/start ────▶ verify token w/ Cloudflare\n │ mint one-time state nonce bound to {id}\n │ ◀──────────── OAuth URL\n │ authorize (identify) ─────────────────────────────▶ consent screen\n │ GET /callback?code&state ◀──────────────────────── redirect back\n │ burn nonce → recover {id},\n │ exchange code, read user id,\n │ PUT role in {id} ─────────▶ role granted ✅\n │ ◀──────────── \"Verified\" result page\n```\n\nThe `/callback` redirect URI is the **same for every server** — the server is\nrecovered from the `state` nonce, so you register just one redirect URI in the\nDiscord app no matter how many servers you shield.\n\nRoles gate **channel access**. Lock `@everyone` down to a single `#verify`\nchannel and grant the rest to the Verified role — see\n[`HARDENING.md`](./HARDENING.md) for the full lockdown + the limits of this model\n(DMs / member-list visibility).\n\n---\n\n## Files\n\n```\nhttp.ts # HTTP trigger — the multi-tenant router (set as HTTP val)\ncron.ts # Cron trigger — daily cleanup + per-server OG card refresh\nkick-bots.ts # Cron trigger — kick members who self-identified as bots (optional)\nmod.ts # Verification logic + routing (Turnstile, OAuth, role grant, UI)\nadmin.ts # Guarded /admin API to register & manage servers at runtime\nguilds.ts # Per-server config registry (CRUD over the captcha_guilds table)\nschema.ts # Centralized SQLite schema + migrations\nconfig.ts # Env split: shared secrets + per-server config loaders\ntheme.ts # 🎨 Default branding (per-server overrides live in each server's config)\nog.ts # Per-server /og.png social card generator\nstore.ts # Blob-backed store of created channel + posted message IDs (per guild)\nchannels.ts # Creates the DMZ channels (used by setup.ts)\nsetup.ts # Bot creates the DMZ channels AND posts every message, for one server\npost-verify.ts # Bot posts (or updates) the Verify button for one server\npost-rules.ts # ... the rules embed\npost-about.ts # ... the \"About the community\" card\npost-honeypot.ts # ... the honeypot \"do not post\" trap\ndeno.json # Val Town / Deno config\n```\n\n---\n\n## Installation\n\nYou'll need ~15 minutes, one or more Discord servers you administer, and free\nCloudflare + Val Town accounts. **One Discord app + bot is shared across every\nserver you shield.**\n\n### 1. Create ONE Discord application & bot\n\n1. Go to the [Discord Developer Portal](https://discord.com/developers/applications)\n → **New Application**.\n2. **OAuth2** tab → copy the **Client ID** and **Client Secret**.\n3. **Bot** tab → **Add Bot** → **Reset Token** and copy the **Bot Token**.\n - The default (non-privileged) intents are fine — this shield never reads\n message content or the member list.\n4. **Invite the bot to each server** you want to shield, with the `bot` scope and\n these permissions:\n\n | Permission | Why |\n | --- | --- |\n | **Manage Roles** | Grant the Verified role on a successful verification |\n | **View Channel** | See the DMZ channels it posts into |\n | **Send Messages** | Post the verify / rules / about / honeypot messages |\n | **Embed Links** | Those messages are rich embeds |\n\n Quick invite URL (replace `CLIENT_ID`) — the `permissions` integer already\n bundles all four:\n ```\n https://discord.com/oauth2/authorize?client_id=CLIENT_ID&scope=bot&permissions=268454912\n ```\n\n **Want the bot to auto-create the DMZ channels** via `setup.ts`? Also grant\n **Manage Channels** — use `permissions=268454928` instead. If you'll make the\n channels yourself, the shield never needs it.\n\n### 2. Per server: Verified role & IDs\n\nFor **each** server you'll shield:\n\n1. Create a **Verified** role. Copy its ID (enable *Developer Mode* in Discord\n → User Settings → Advanced, then right-click the role → **Copy ID**).\n2. **Important — role hierarchy:** drag the **bot's own role above the Verified\n role** in Server Settings → Roles. A bot can only assign roles *below* its\n highest role.\n3. Right-click the server → **Copy Server ID** (that's the **Guild ID**).\n4. (Recommended) Lock the server down: deny `@everyone` **View Channel**\n everywhere except a single `#verify` channel; grant the real channels to the\n Verified role. See [`HARDENING.md`](./HARDENING.md).\n\nYou'll register these IDs with the admin API in step 6.\n\n### 3. Get a Cloudflare Turnstile keypair (free)\n\n1. Cloudflare Dashboard → **Turnstile** → **Add site**.\n2. Add the domain you'll serve the portal from (your val's domain — e.g.\n `your-val.val.run`, or a custom domain). You can add `localhost` for testing.\n3. Copy the **Site Key** and **Secret Key**.\n\nBecause the Turnstile site key is **domain-bound** and every server shares the\nportal domain, **one keypair covers all your servers**. (A server on its own\ncustom domain can set its own keypair — see the admin API fields.)\n\n### 4. Create the val on Val Town\n\n1. **Remix this template** into your own Val Town project (or create a new\n project and copy these files in).\n2. Set the triggers:\n - **`http.ts`** → make it an **HTTP** val. Note its URL — that's your portal\n base (servers live at `/g/{guildId}`).\n - **`cron.ts`** → make it a **Cron** val on a daily schedule (e.g. `0 6 * * *`).\n3. Add the **shared** environment variables below (Val Town → your project →\n **Environment Variables**). Per-server values are NOT env vars — they go\n through the admin API.\n\n### 5. Configure the OAuth redirect (once)\n\nBack in the Discord Developer Portal → **OAuth2** → **Redirects**, add the single\nshared callback:\n\n```\nhttps:///callback\n```\n\nThis must match exactly, and it's the **only** redirect URI you ever need, for\nany number of servers. (A server on a custom domain that sets its own\n`redirectUriOverride` needs that URI registered too.)\n\n### 6. Register each server (admin API)\n\nWith `ADMIN_SECRET` set (step env table below), register a server by POSTing its\nconfig. Minimum is the guild id + role id; add branding and channels as you like:\n\n```bash\ncurl -X POST https:///admin/guilds \\\n -H \"authorization: Bearer $ADMIN_SECRET\" \\\n -H \"content-type: application/json\" \\\n -d '{\n \"guildId\": \"111111111111111111\",\n \"roleId\": \"222222222222222222\",\n \"serverName\": \"My Community\",\n \"accentColor\": \"#5865F2\",\n \"logoUrl\": \"https://example.com/logo.png\",\n \"portalUrl\": \"https://your-portal-domain/g/111111111111111111\",\n \"alertWebhookUrl\": \"https://discord.com/api/webhooks/...\"\n }'\n```\n\nMembers then verify at `https:///g/111111111111111111`.\nRepeat for each server. See [Managing servers](#managing-servers) for the full\nfield list and the other verbs.\n\n> Set **`portalUrl`** to the server's full portal URL (`.../g/{guildId}`) — the\n> Verify buttons and the OG card image are built from it.\n\n### 7. Set up each server's DMZ & post the messages\n\nThe **DMZ** is the handful of channels an unverified member can see. The tools\nact on **one server at a time** — pass the guild id as the first argument, or set\n`TOOL_GUILD_ID` in the environment before running. You have two ways to set it\nup — pick one.\n\n**Option A — let the bot build it.** Grant the bot **Manage Channels** (step 1),\nthen run **`setup.ts`** with the guild id. It creates a `Welcome` category with\n`#about`, `#rules`, `#verify`, and `#do-not-post` (read-only to `@everyone`,\nhoneypot left open), then posts every message into them. Channel + message IDs\nare saved to blob storage (namespaced per server), so you never copy an ID by\nhand.\n\n**Option B — use your own channels.** Create the channels yourself, set the\nchannel IDs on the server's config (admin API: `verifyChannelId`,\n`rulesChannelId`, `aboutChannelId`, `honeypotChannelId`), and run the post\nscripts individually:\n\n| Script | Posts | Config field |\n| --- | --- | --- |\n| `post-about.ts` | \"About the community\" card (+ Verify button) | `aboutChannelId` |\n| `post-rules.ts` | The rules embed | `rulesChannelId` |\n| `post-verify.ts` | The Verify button | `verifyChannelId` |\n| `post-honeypot.ts` | A \"do not post\" trap that outs spam bots | `honeypotChannelId` |\n\nEither way: **re-running a post script edits its message in place** — it doesn't\npost a duplicate. See [Updating messages](#updating-messages) below. Done — new\nmembers can now read what you're about, see the rules, and verify. 🎉\n\n---\n\n## Environment variables\n\nThese are **shared across all servers** — per-server values live in each\nserver's config row (admin API), not in env.\n\n### Required\n\n| Variable | What it is |\n| --- | --- |\n| `DISCORD_CLIENT_ID` | OAuth2 Client ID of the **one** shared app |\n| `DISCORD_CLIENT_SECRET` | OAuth2 Client Secret |\n| `DISCORD_BOT_TOKEN` | Bot token (the bot is invited to each server) |\n| `ADMIN_SECRET` | Bearer token guarding the `/admin` API. Unset = admin API disabled |\n\n### Optional (shared)\n\n| Variable | Default | What it is |\n| --- | --- | --- |\n| `TURNSTILE_SITE_KEY` | _(none)_ | Default Turnstile site key (a server may override) |\n| `TURNSTILE_SECRET_KEY` | _(none)_ | Default Turnstile secret key (a server may override) |\n| `TOOL_GUILD_ID` | _(none)_ | Which server `setup.ts` / `post-*.ts` act on (or pass as the first CLI arg) |\n\nA server needs Turnstile keys from **either** the shared defaults above **or**\nits own config. With one portal domain, set the shared defaults once and you're\ndone.\n\n### Legacy (upgrading from the single-guild build only)\n\nIf you're upgrading an old single-server deployment, leave its existing env vars\nin place: on first boot the shield **auto-seeds a server config row** from them\n(and migrates the audit log + stored channel/message IDs), so the server keeps\nworking and `/` redirects to its `/g/{guildId}`. These are read once for that\nmigration: `DISCORD_GUILD_ID`, `DISCORD_ROLE_ID`, `VERIFY_SERVER_NAME`,\n`VERIFY_REDIRECT_URI`, `VERIFY_PORTAL_URL`, `VERIFY_ALERT_WEBHOOK`,\n`VERIFY_RAID_THRESHOLD`, `VERIFY_RAID_WINDOW_MIN`, `VERIFY_ALERT_COOLDOWN_MIN`,\nand `DISCORD_*_CHANNEL_ID`. After migrating you can manage everything through the\nadmin API. New installs should ignore these entirely.\n\n---\n\n## Managing servers\n\nAll routes live under `/admin/guilds` and require `Authorization: Bearer\n$ADMIN_SECRET`. If `ADMIN_SECRET` is unset the whole API returns `404`. The\nTurnstile **secret** is never echoed back (responses report only\n`hasTurnstileSecretKey`).\n\n| Method | Route | Does |\n| --- | --- | --- |\n| `GET` | `/admin/guilds` | List all servers |\n| `POST` | `/admin/guilds` | Create a server (`409` if it already exists) |\n| `GET` | `/admin/guilds/{id}` | Fetch one server |\n| `PUT` | `/admin/guilds/{id}` | Create or replace a server |\n| `PATCH` | `/admin/guilds/{id}` | Partial update (only the fields you send) |\n| `DELETE` | `/admin/guilds/{id}` | Remove a server |\n\nIn `PATCH`, a field sent as `null` **clears** that override (falls back to the\ndefault); fields you omit are left unchanged.\n\n### Config fields\n\n`guildId` and `roleId` are required to create a server. Everything else is\noptional; branding fields left unset fall back to `theme.ts`.\n\n| Field | Type | Notes |\n| --- | --- | --- |\n| `guildId` | string | The Discord server ID (numeric) |\n| `roleId` | string | The Verified role ID to grant (numeric) |\n| `botRoleId` | string | Role given (via Onboarding) to self-identified bots; the `kick-bots.ts` cron kicks holders. Unset = off |\n| `serverName` | string | Display name on the portal + embeds |\n| `disabled` | boolean | When true, the portal/callback treat the server as unknown |\n| `brandName` | string | Branding name (defaults to `serverName`, then `theme.ts`) |\n| `logoUrl` | string | Square logo (portal card, OG card, rules thumbnail) |\n| `accentColor` / `accentColorBright` | hex string | Portal + button accents (e.g. `#5865F2`) |\n| `embedColor` | int or `#RRGGBB` | Discord embed stripe color |\n| `ogHeadline` / `ogTagline` | string | Social card copy |\n| `ogFallbackImage` | string | Shown before the cron first renders the card |\n| `rules` | `{name,value}[]` | Rules embed contents (`post-rules.ts`) |\n| `about` | `{tagline,description,highlights}` | About card contents (`post-about.ts`) |\n| `turnstileSiteKey` / `turnstileSecretKey` | string | Override the shared Turnstile keypair |\n| `alertWebhookUrl` | string | Discord webhook for this server's raid alerts |\n| `raidThreshold` | number | Successful verifies in the window that trip an alert (default 15) |\n| `raidWindowMs` | number | Raid look-back window in ms (default 5 min) |\n| `alertCooldownMs` | number | Min gap between alerts in ms (default 15 min) |\n| `verifyChannelId` / `rulesChannelId` / `aboutChannelId` / `honeypotChannelId` | string | DMZ channels for the post tools |\n| `portalUrl` | string | This server's portal base, `.../g/{guildId}` (Verify button + card image) |\n| `redirectUriOverride` | string | Override `/callback` (only for a custom per-server domain) |\n\n```bash\n# Re-skin a server later\ncurl -X PATCH https:///admin/guilds/111111111111111111 \\\n -H \"authorization: Bearer $ADMIN_SECRET\" \\\n -d '{\"accentColor\":\"#43B581\",\"logoUrl\":\"https://example.com/new.png\"}'\n\n# Temporarily pause verification for a server\ncurl -X PATCH https:///admin/guilds/111111111111111111 \\\n -H \"authorization: Bearer $ADMIN_SECRET\" -d '{\"disabled\":true}'\n\n# Remove a server\ncurl -X DELETE https:///admin/guilds/111111111111111111 \\\n -H \"authorization: Bearer $ADMIN_SECRET\"\n```\n\n---\n\n## Make it yours\n\n`theme.ts` holds the **default** branding for every server — edit it and the\nportal page, social card, and Discord embeds re-skin together for any server that\nhasn't set its own overrides:\n\n- **`brand.name`** — fallback community name.\n- **`brand.logoUrl`** — a square logo (swap the placeholder cat for yours).\n- **`brand.accentColor` / `accentColorBright` / `embedColor`** — the accent.\n- **`brand.ogHeadline` / `ogTagline`** — the social card copy.\n- **`rules`** — the default rules `post-rules.ts` posts.\n- **`about`** — the default tagline, description, and highlights.\n\nTo brand an **individual** server differently, set the matching fields on its\nconfig via the admin API (`accentColor`, `logoUrl`, `rules`, `about`, …) — those\noverride the `theme.ts` defaults for that server only. Secrets never live in the\nsource.\n\nTo update what's already posted: change the config (or `theme.ts`) and **re-run\nthe matching post script** for that server — it edits the live message in place.\n\n---\n\n## Updating messages\n\nWhen a post tool posts a message, it saves that message's ID to blob storage\n(`store.ts`), namespaced by guild. Run the same script again (for the same\nserver) and it **edits the existing message** instead of posting a duplicate.\n\nHow a channel is resolved, in priority order:\n\n1. an explicit ID passed in code (`postRulesMessage(config, { channelId })`),\n2. a channel the bot created via `setup.ts` (blob store, per guild),\n3. the channel ID on the server's config (`rulesChannelId`, etc.).\n\nSo the bot-created channels win automatically, and hand-wired config IDs still\nwork as a fallback. The post functions also accept `{ messageId }` to target a\nspecific message, or `{ forceNew: true }` to post a fresh one. If a stored\nmessage was deleted in Discord, the next run notices the `404` and posts a new\none.\n\n> Blob keys used: `captcha_shield_v1_{guildId}_channel_`,\n> `captcha_shield_v1_{guildId}_message_`, and\n> `captcha_shield_v1_{guildId}_category` (one ID per key, so `setup.ts` can post\n> all four messages concurrently), plus `verify_og_png_v1_{guildId}` (the cached\n> social card).\n\n---\n\n## Bot self-identification trap (optional)\n\nA honeypot that catches scripted accounts before they ever reach the portal,\nusing Discord **Onboarding** + the `kick-bots.ts` cron:\n\n1. In **Server Settings → Onboarding**, add a prejoin **question** like *\"Are you\n an automated account or a bot?\"* with two answers:\n - **\"Yes\"** → assign a **\"Self-identified Bot\"** role.\n - **\"No\"** → assign your **Unverified** role (the one that reveals `#verify`).\n2. Register that bot role on the server: set **`botRoleId`** to its ID via the\n admin API.\n3. Set **`kick-bots.ts`** as a second **Cron** val on a frequent schedule (e.g.\n every 15 minutes, `*/15 * * * *`). It sweeps every server with a `botRoleId`\n and **kicks** members still holding that role (a 5-minute grace skips\n brand-new joins so a human who mis-clicked can re-do onboarding).\n\nReal humans read the question and pick \"No\"; naive bots/self-bots that auto-pick\nthrough Onboarding select themselves into the kick list.\n\n> **Extra requirements for this feature only:** the bot needs the\n> **GUILD_MEMBERS** privileged intent (Developer Portal → Bot → *Privileged\n> Gateway Intents*) so it can list members, and the **Kick Members** permission\n> in each server (add bit `0x2` to the invite `permissions`). The rest of the\n> shield never needs either.\n\n---\n\n## Adding more servers\n\nJust register another server with the admin API (`POST /admin/guilds`) — no\nredeploy, no second val. The one deployment serves them all: each server's\nconfig + branding is keyed by guild id in SQLite, the state nonces / audit log /\nraid alerts are scoped per guild, and the single shared bot + OAuth app handles\nevery server through the one `/callback` redirect URI.\n\n---\n\n## Troubleshooting\n\nThe portal turns Discord's API errors into plain-language messages. Common ones:\n\n| Symptom | Cause / fix |\n| --- | --- |\n| Portal says \"This verification link isn't active\" | The guild id in the URL isn't registered, or the server is `disabled`. Register it via the admin API. |\n| \"You're not in the server yet\" | The user must **join** the Discord before verifying (this is an already-members gate). |\n| \"The bot doesn't have permission to grant the role\" | Move the **bot's role above** the Verified role, and ensure it has **Manage Roles**. |\n| \"The verification bot isn't connected to this server\" | Wrong `guildId` on the config, or the bot was never invited to that server. |\n| \"The verified role no longer exists\" | Wrong/deleted `roleId` on the config. |\n| CAPTCHA never lets you continue | No Turnstile keys for that server (set shared `TURNSTILE_*` env or per-server keys), or the portal domain isn't added to the Turnstile site. |\n| Admin API returns `401` | Missing/incorrect `Authorization: Bearer $ADMIN_SECRET`. A `404` on `/admin/*` means `ADMIN_SECRET` isn't set. |\n| OAuth \"redirect URI mismatch\" | The single `/callback` URL in the Developer Portal must match your portal exactly. |\n| `/g/{id}/og.png` shows the fallback image | The cron hasn't generated that server's card yet — run `cron.ts` once manually. |\n\nEvery attempt (success or failure) is recorded in the `captcha_verify_log_v2`\nSQLite table with the `guild_id` and a `detail` column carrying the exact Discord\nstatus/error code, then pruned after 7 days.\n\n---\n\n## Security notes\n\n- OAuth uses the **`identify` scope only** — the shield reads a Discord user ID\n and nothing else.\n- State nonces are **single-use, atomically burned, and bound to one server**;\n concurrent callbacks for the same nonce can't both succeed, they expire after\n 10 minutes, and a nonce minted for one server can't grant a role in another.\n- The admin API compares the bearer token in **constant time** and never echoes\n the Turnstile secret back.\n- Turnstile tokens are verified **server-side** against Cloudflare.\n- This is an **\"already-members\" gate**: it stops unverified users from accessing\n gated channels, but Discord roles don't block DMs or member-list visibility on\n their own. [`HARDENING.md`](./HARDENING.md) covers closing those gaps with\n Membership Screening / lockdown.\n\n---\n\n## License\n\nMIT — do whatever you like.

This doc explains exactly what it does and does not stop, and the options\nfor tightening it. None of this is required to run the shield — it works as-is —\nbut read it before relying on it as your only line of defense.\n\n## What the shield does\n\nA user joins the Discord → solves the CAPTCHA → Discord OAuth → the bot grants\nthe **Verified** role, which *unlocks* channels.\n\n- **Stops:** posting/participating in channels gated behind the Verified role\n (assuming `@everyone` is locked down).\n- **Does NOT stop (the gap):** a member who has *joined but not verified* can\n still (a) appear in / read the **member list** of any channel they can view,\n and (b) **DM** other members they share the server with.\n\nRoles gate *channel access*, not DMs or member-list visibility. Discord has **no\n\"cannot DM\" permission** — DMs are allowed between users who share a server\n(subject to each user's privacy settings + the server DM spam filter).\n\n## What actually restricts a joined user\n\nOnly two things meaningfully limit a joined-but-unverified user:\n\n1. **Membership Screening \"pending\" state** — Discord's native gate. New joins\n are \"pending\" until they complete screening; pending members **cannot DM\n other members or interact**. This is the real lever for the DM/member-list\n vector.\n2. **Hard channel-permission lockdown** — `@everyone` can view only a single\n `#verify` channel, so member-list exposure is limited to who can see that one\n channel. Still does not block DMs.\n\n## Options (with tradeoffs)\n\n### A. Server-config lockdown — do this regardless (little/no code)\n- `@everyone`: deny **View Channel** everywhere except one `#verify` channel;\n strip most perms. Verified role grants View on the real channels.\n- Stack native levers: raise **Verification Level** (Medium/High), enable\n **AutoMod** + **DM spam filter**, enable **Membership Screening** +\n **Onboarding**.\n- Limits member-list exposure; does not by itself stop DMs.\n\n### B. Membership Screening (the real DM blocker)\n- New joins are \"pending\" until they pass screening → can't DM/interact.\n- **Caveat:** native screening completion is \"agree to the rules\" (a client\n gesture a determined bot can automate), so it isn't bot-proof on its own. Pair\n it with the CAPTCHA: screening blocks DMs, the CAPTCHA blocks bots.\n\n### B½. Onboarding bot-trap + kick cron (no gateway needed)\n- In **Server Settings → Onboarding**, add a prejoin **question** — *\"Are you an\n automated account or a bot?\"* Answer **\"Yes\"** → assign a *Self-identified Bot*\n role; answer **\"No\"** → assign your *Unverified* role (which reveals `#verify`).\n- Set the bot role as the server's **`botRoleId`** (admin API), and run\n **`kick-bots.ts`** as a Cron val (e.g. `*/15 * * * *`). It sweeps every server\n with a `botRoleId` and **kicks** holders of that role (a 5-min grace skips\n brand-new joins). Humans pick \"No\"; scripts that auto-advance Onboarding pick\n themselves into the kick list.\n- Unlike option C this needs **no always-on gateway** — it's a periodic REST\n sweep. It does need the **GUILD_MEMBERS** privileged intent (to list members)\n and the **Kick Members** permission. It complements, not replaces, screening:\n it catches the naive-bot pattern, not a careful human-like bot.\n\n### C. Gateway bot for join handling (quarantine + auto-kick)\n- React to `GUILD_MEMBER_ADD`: assign a **Quarantine** role (View denied\n everywhere except `#verify`) and auto-kick if unverified within N minutes.\n- Quarantine limits member-list exposure and the auto-kick shrinks the DM\n window, but does **not** fully block DMs (mutual server).\n- **Cost:** needs a persistent gateway (WebSocket) connection. **Val Town is\n serverless and not suited to an always-on gateway.** You'd need a separate\n always-on host (a small VPS, Fly/Railway, a Cloudflare Durable Object with a\n gateway lib, or a hosted bot framework). The CAPTCHA portal can stay on Val\n Town as the unlock step. Requires the **GUILD_MEMBERS** privileged intent.\n\n### D. Combine (recommended target)\n- Membership Screening / Onboarding holds joiners pending (blocks DMs +\n member-list) and routes them to the CAPTCHA portal; the bot grants Verified\n after CAPTCHA.\n\n## A quick win available now\n\nOn successful verify, also **remove** an \"Unverified\"/\"Quarantine\" role (not just\nadd Verified): add an `unverifiedRoleId` field to the per-server config (a column\nin `captcha_guilds` + the admin API, alongside `roleId`) and a `DELETE\n/guilds/{guild}/members/{user}/roles/{roleId}` call on success in `mod.ts`. Keep\nit per-server, not an env var, so each shielded server can use its own quarantine\nrole. (Auto-*assigning* that role on join still needs a gateway bot or an\nOnboarding default role.)\n",[],[398],"b5e6c93b-b6df-44bc-8dc9-4962479dfbee","AGENTS.md","5747987a-66b3-11f1-bed8-1607ee4eb77e",94,["D",1781305585120],"You are an advanced assistant specialized in generating Val Town code.\n\n---\n\n## This project — Discord CAPTCHA Shield (multi-tenant)\n\nA CAPTCHA + Discord OAuth verification gate. **One deployment shields many\nDiscord servers**, each with its own config and branding. Read `README.md` for\nthe user-facing model; this section is the architecture map for editing the code.\n\n### Shape\n\n- **One shared Discord app + bot** for all servers, in shared env\n (`DISCORD_CLIENT_ID` / `_SECRET` / `DISCORD_BOT_TOKEN`). Per-server values\n (role, branding, channels, alert tuning, optional Turnstile keys) live in the\n `captcha_guilds` SQLite table, **not** env.\n- **Routing** (`mod.ts` `handleVerifyRequest`): per-server pages under\n `/g/{guildId}` (`` = portal, `/start`, `/og.png`); a single shared\n `/callback`; and the guarded `/admin/*` API. The OAuth `state` nonce carries\n the guild id, so **one** registered `/callback` redirect URI serves every\n server — never add per-guild redirect URIs to the OAuth routing.\n- **Config flow**: `config.ts` splits `loadSharedEnv()` (secrets) from\n `loadGuildConfig(guildId)` (merges a `captcha_guilds` row with shared env →\n `VerifyConfig`). Tools use `loadGuildToolConfig()` (no Turnstile requirement).\n `guilds.ts` is the CRUD registry; `admin.ts` is the bearer-guarded HTTP layer\n over it. Branding resolves via `theme.ts` `resolveTheme()` (defaults) layered\n with a guild's overrides (`resolveGuildTheme()`).\n- **Per-guild scoping**: state nonces + audit log carry `guild_id`; raid alerts\n namespace the guild into the alert `kind` (`raid:`); blob keys in\n `store.ts` and the OG card in `og.ts` are keyed by guild id.\n\n### Invariants — don't break these\n\n- **Schema migrations: rename, never ALTER.** Per the SQLite guidance below,\n adding a column means a **new table name** (e.g. `captcha_verify_log_v2`)\n created fresh with the column, plus a one-time data copy where it matters — see\n `schema.ts`. Do not reintroduce `ALTER TABLE`. All table DDL lives in\n `schema.ts` (`ensureSchema()`); `mod.ts`/`guilds.ts` import the table-name\n constants from there.\n- **The shared `/callback` must stay singular.** The guild comes from the state\n nonce (`consumeState` returns it), not the path.\n- **Never echo secrets.** The admin API redacts `turnstileSecretKey` and\n compares `ADMIN_SECRET` in constant time (`admin.ts`).\n- **Legacy upgrades are automatic.** `seedLegacyGuildFromEnv()` (config.ts) runs\n once to seed a `captcha_guilds` row from old single-guild env vars and migrate\n the log + blob IDs. Keep it idempotent.\n\n### Verifying changes\n\nType-check + lint are the local ceiling (the Discord/Turnstile/SQLite paths need\na Val Town deploy): `deno check --allow-import *.ts` and `deno lint *.ts`. The\n`no-import-prefix` lint warnings on `https://esm.town` / `https://esm.sh` imports\nare expected (Val Town requires those URL imports) — ignore them.\n\n---\n\n## Core Guidelines\n\n- Ask clarifying questions when requirements are ambiguous\n- Provide complete, functional solutions rather than skeleton implementations\n- Test your logic against edge cases before presenting the final solution\n- Ensure all code follows Val Town's specific platform requirements\n- If a section of code that you're working on is getting too complex, consider refactoring it into subcomponents\n\n## Code Standards\n\n- Generate code in TypeScript or TSX\n- Add appropriate TypeScript types and interfaces for all data structures\n- Prefer official SDKs or libraries than writing API calls directly\n- Ask the user to supply API or library documentation if you are at all unsure about it\n- **Never bake in secrets into the code** - always use environment variables\n- Include comments explaining complex logic (avoid commenting obvious operations)\n- Follow modern ES6+ conventions and functional programming practices if possible\n\n## Types of triggers\n\n### 1. HTTP Trigger\n\n- Create web APIs and endpoints\n- Handle HTTP requests and responses\n- Example structure:\n\n```ts\nexport default async function (req: Request) {\n return new Response(\"Hello World\");\n}\n```\n\nFiles that are HTTP triggers have http in their name like `foobar.http.tsx`\n\n### 2. Cron Triggers\n\n- Run on a schedule\n- Use cron expressions for timing\n- Example structure:\n\n```ts\nexport default async function () {\n // Scheduled task code\n}\n```\n\nFiles that are Cron triggers have cron in their name like `foobar.cron.tsx`\n\n### 3. Email Triggers\n\n- Process incoming emails\n- Handle email-based workflows\n- Example structure:\n\n```ts\nexport default async function (email: Email) {\n // Process email\n}\n```\n\nFiles that are Email triggers have email in their name like `foobar.email.tsx`\n\n\n## Val Town Standard Libraries\n\nVal Town provides several hosted services and utility functions.\n\n### Blob Storage\n\n```ts\nimport { blob } from \"https://esm.town/v/std/blob\";\nawait blob.setJSON(\"myKey\", { hello: \"world\" });\nlet blobDemo = await blob.getJSON(\"myKey\");\nlet appKeys = await blob.list(\"app_\");\nawait blob.delete(\"myKey\");\n```\n\n### SQLite\n\n```ts\nimport { sqlite } from \"https://esm.town/v/stevekrouse/sqlite\";\nconst TABLE_NAME = 'todo_app_users_2';\n// Create table - do this before usage and change table name when modifying schema\nawait sqlite.execute(`CREATE TABLE IF NOT EXISTS ${TABLE_NAME} (\n id INTEGER PRIMARY KEY AUTOINCREMENT,\n name TEXT NOT NULL\n)`);\n// Query data\nconst result = await sqlite.execute(`SELECT * FROM ${TABLE_NAME} WHERE id = ?`, [1]);\n```\n\nNote: When changing a SQLite table's schema, change the table's name (e.g., add _2 or _3) to create a fresh table.\n\n### OpenAI\n\n```ts\nimport { OpenAI } from \"https://esm.town/v/std/openai\";\nconst openai = new OpenAI();\nconst completion = await openai.chat.completions.create({\n messages: [\n { role: \"user\", content: \"Say hello in a creative way\" },\n ],\n model: \"gpt-4o-mini\",\n max_tokens: 30,\n});\n```\n\n### Email\n\n```ts\nimport { email } from \"https://esm.town/v/std/email\";\n// By default emails the owner of the val\nawait email({ \n subject: \"Hi\", \n text: \"Hi\", \n html: \"

Hi

\"\n});\n```\n\n## Val Town Utility Functions\n\nVal Town provides several utility functions to help with common project tasks.\n\n### Importing Utilities\n\nAlways import utilities with version pins to avoid breaking changes:\n\n```ts\nimport { parseProject, readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n```\n\n### Available Utilities\n\n\n#### **serveFile** - Serve project files with proper content types\n\nFor example, in Hono:\n\n```ts\n// serve all files in frontend/ and shared/\napp.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\napp.get(\"/shared/*\", c => serveFile(c.req.path, import.meta.url));\n```\n\n#### **readFile** - Read files from within the project:\n\n```ts\n// Read a file from the project\nconst fileContent = await readFile(\"/frontend/index.html\", import.meta.url);\n```\n\n#### **listFiles** - List all files in the project\n\n```ts\nconst files = await listFiles(import.meta.url);\n```\n\n#### **parseProject** - Extract information about the current project from import.meta.url\n\nThis is useful for including info for linking back to a val, ie in \"view source\" urls:\n\n```ts\nconst projectVal = parseProject(import.meta.url);\nconsole.log(projectVal.username); // Owner of the project\nconsole.log(projectVal.name); // Project name\nconsole.log(projectVal.version); // Version number\nconsole.log(projectVal.branch); // Branch name\nconsole.log(projectVal.links.self.project); // URL to the project page\n```\n\nHowever, it's *extremely importing* to note that `parseProject` and other Standard Library utilities ONLY RUN ON THE SERVER.\nIf you need access to this data on the client, run it in the server and pass it to the client by splicing it into the HTML page\nor by making an API request for it.\n\n## Val Town Platform Specifics\n\n- **Redirects:** Use `return new Response(null, { status: 302, headers: { Location: \"/place/to/redirect\" }})` instead of `Response.redirect` which is broken\n- **Images:** Avoid external images or base64 images. Use emojis, unicode symbols, or icon fonts/libraries instead\n- **AI Image:** To inline generate an AI image use: `

`\n- **Storage:** DO NOT use the Deno KV module for storage\n- **Browser APIs:** DO NOT use the `alert()`, `prompt()`, or `confirm()` methods\n- **Weather Data:** Use open-meteo for weather data (doesn't require API keys) unless otherwise specified\n- **View Source:** Add a view source link by importing & using `import.meta.url.replace(\"ems.sh\", \"val.town)\"` (or passing this data to the client) and include `target=\"_top\"` attribute\n- **Error Debugging:** Add `` to HTML to capture client-side errors\n- **Error Handling:** Only use try...catch when there's a clear local resolution; Avoid catches that merely log or return 500s. Let errors bubble up with full context\n- **Environment Variables:** Use `Deno.env.get('keyname')` when you need to, but generally prefer APIs that don't require keys\n- **Imports:** Use `https://esm.sh` for npm and Deno dependencies to ensure compatibility on server and browser\n- **Storage Strategy:** Only use backend storage if explicitly required; prefer simple static client-side sites\n- **React Configuration:** When using React libraries, pin versions with `?deps=react@18.2.0,react-dom@18.2.0` and start the file with `/** @jsxImportSource https://esm.sh/react@18.2.0 */`\n- Ensure all React dependencies and sub-dependencies are pinned to the same version\n- **Styling:** Default to using TailwindCSS via `` unless otherwise specified\n\n## Project Structure and Design

utils.ts # Shared types and functions\n```\n\n### Backend (Hono) Best Practices\n\n- Hono is the recommended API framework\n- Main entry point should be `backend/index.ts`\n- **Static asset serving:** Use the utility functions to read and serve project files:\n ```ts\n import { readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n \n // serve all files in frontend/ and shared/\n app.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\n app.get(\"/shared/*\", c => serveFile(c.req.path, import.meta.url));\n \n // For index.html, often you'll want to bootstrap with initial data\n app.get(\"/\", async c => {\n let html = await readFile(\"/frontend/index.html\", import.meta.url);\n \n // Inject data to avoid extra round-trips\n const initialData = await fetchInitialData();\n const dataScript = ``;\n \n html = html.replace(\"\", `${dataScript}`);\n return c.html(html);\n });\n ```\n- Create RESTful API routes for CRUD operations\n- Always include this snippet at the top-level Hono app to re-throwing errors to see full stack traces:\n ```ts\n // Unwrap Hono errors to see original error details\n app.onError((err, c) => {\n throw err;\n });\n ```\n\n### Database Patterns\n- Run migrations on startup or comment out for performance\n- Change table names when modifying schemas rather than altering\n- Export clear query functions with proper TypeScript typing\n\n## Common Gotchas and Solutions\n\n1. **Environment Limitations:** \n - Val Town runs on Deno in a serverless context, not Node.js\n - Code in `shared/` must work in both frontend and backend environments\n - Cannot use `Deno` keyword in shared code\n - Use `https://esm.sh` for imports that work in both environments\n\n2. **SQLite Peculiarities:**\n - Limited support for ALTER TABLE operations\n - Create new tables with updated schemas and copy data when needed\n - Always run table creation before querying\n\n3. **React Configuration:**\n - All React dependencies must be pinned to 18.2.0\n - Always include `@jsxImportSource https://esm.sh/react@18.2.0` at the top of React files\n - Rendering issues often come from mismatched React versions\n\n4. **File Handling:**\n - Val Town only supports text files, not binary\n - Use the provided utilities to read files across branches and forks\n - For files in the project, use `readFile` helpers\n\n5. **API Design:**\n - `fetch` handler is the entry point for HTTP vals\n - Run the Hono app with `export default app.fetch // This is the entry point for HTTP vals`\n\n",[],[406],"889e60c2-2fe0-453d-85e3-b7a422bacfe0",".vtignore","55fdb2ec-66b3-11f1-a5fa-1607ee4eb77e",78,["D",1781305585119],".git\n.vscode\n.cursorrules\n.DS_Store\nnode_modules\nvendor",[],[414],"78e7f1cd-c6b6-40ee-838f-d72c1cb64a99",".gitignore","f2e6812c-668d-11f1-8d84-1607ee4eb77e",37,["D",1781289527671],"#

If you need to build on top of it to correct\n earlier mistakes, a new topic branch is created by forking at\n the tip of the \"master\". This is not strictly necessary, but\n it makes it easier to keep your history simple.\n\n * Whenever you need to test or publish your changes to topic\n branches, merge them into \"next\" branch.\n\nThe script, being an example, hardcodes the publish branch name\nto be \"next\", but it is trivial to make it configurable via\n$GIT_DIR/config mechanism.\n\nWith this workflow, you would want to know:\n\n(1) ... if a topic branch has ever been merged to \"next\". Young\n topic branches can have stupid mistakes you would rather\n clean up before publishing, and things that have not been\n merged into other branches can be easily rebased without\n affecting other people. But once it is published, you would\n not want to rewind it.\n\n(2) ... if a topic branch has been fully merged to \"master\".\n Then you can delete it. More importantly, you should not\n build on top of it -- other people may already want to\n change things related to the topic as patches against your\n \"master\", so if you need further changes, it is better to\n fork the topic (perhaps with the same name) afresh from the\n tip of \"master\".\n\nLet's look at this example:\n\n\t\t o---o---o---o---o---o---o---o---o---o \"next\"\n\t\t / / / /\n\t\t / a---a---b A / /\n\t\t/ / / /\n\t / / c---c---c---c B /\n\t / / / \\ /\n\t / / / b---b C \\ /\n\t / / / / \\ /\n ---o---o---o---o---o---o---o---o---o---o---o \"master\"\n\n\nA, B and C are topic branches.\n\n * A has one fix since it was merged up to \"next\".\n\n * B has finished. It has been fully merged up to \"master\" and \"next\",\n and is ready to be deleted.\n\n * C has not merged to \"next\" at all.\n\nWe would want to allow C to be rebased, refuse A, and encourage\nB to be deleted.\n\nTo compute (1):\n\n\tgit rev-list ^master ^topic next\n\tgit rev-list ^master next\n\n\tif these match, topic has not merged in next at all.\n\nTo compute (2):\n\n\tgit rev-list master..topic\n\n\tif this is empty, it is fully merged to \"master\".\n\nDOC_END\n",[],[437,707,741],"33530d0d-d5c2-4cb8-ae11-d26f4df79d58","pre-push.sample","f377d88e-668d-11f1-9138-1607ee4eb77e",57,["D",1781289528611],"#!/bin/sh\n\n# An example hook script to verify what is about to be pushed.
