Auth + Production Hardening Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Add username + password + role auth on the web app and close the v1.1.0 production-readiness gaps (gated SSE/QR, robots, container non-root, rate limits) so the bot is safe to expose at wabot.04080616.xyz.

Architecture: Roll-our-own session cookie. bcryptjs for password hashing (pure JS, edge-safe build), Web Crypto's HMAC-SHA256 for cookie signing in the edge-runtime middleware. Two roles (admin / user) on the existing operators table. Defense-in-depth: middleware verifies the cookie on every request, every Server Action also calls requireUser() / requireAdmin(). Existing getSeededOperator() becomes a compat shim that delegates to getCurrentUser() so the 66 existing call sites and ~12 test mocks keep working.

Tech Stack: Next.js 16 App Router + React 19, edge runtime middleware, Drizzle ORM + Postgres, vitest, bcryptjs, Web Crypto.

Task 1: Migration 0010 — username + password_hash on operators

Files:

• Modify: packages/db/src/schema.ts (around the operators table block)

• Generate: packages/db/migrations/0010_<name>.sql

• Modify: packages/db/migrations/meta/_journal.json (drizzle-kit auto-updates)

• Step 1: Edit packages/db/src/schema.ts — add the two columns to operators

Find the existing operators table block (around line 1) and modify so it reads:

export const operators = pgTable(
  "operators",
  {
    id: uuid("id").primaryKey().defaultRandom(),
    username: text("username").notNull(),
    passwordHash: text("password_hash"),
    displayName: text("display_name").notNull(),
    role: text("role").notNull().default("admin"),
    defaultTimezone: text("default_timezone").notNull().default("Asia/Kuala_Lumpur"),
    createdAt: timestamp("created_at", { withTimezone: true }).notNull().defaultNow(),
  },
  (t) => ({
    usernameUnique: uniqueIndex("operators_username_uq").on(sql`lower(${t.username})`),
  }),
);

Add the import at the top of schema.ts if not already present:

import { sql } from "drizzle-orm";

• Step 2: Generate the SQL migration

NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/db generate

Expected: a new file packages/db/migrations/0010_<random_name>.sql containing:

• ALTER TABLE "operators" ADD COLUMN "username" text NOT NULL; — but Drizzle will write it as a single ALTER TABLE ADD COLUMN per column.
• The unique index DDL.

The auto-generated NOT NULL on username will fail on the existing row (it has no value yet). Open the generated .sql file and replace its contents with:

-- Add username + password_hash to operators. Backfill the seed row to
-- 'admin' so the NOT NULL constraint succeeds; password_hash stays
-- nullable so the operator is forced to set one via the CLI before
-- they can sign in.
ALTER TABLE "operators" ADD COLUMN "username" text;--> statement-breakpoint
ALTER TABLE "operators" ADD COLUMN "password_hash" text;--> statement-breakpoint
UPDATE "operators" SET "username" = 'admin' WHERE "username" IS NULL;--> statement-breakpoint
ALTER TABLE "operators" ALTER COLUMN "username" SET NOT NULL;--> statement-breakpoint
CREATE UNIQUE INDEX "operators_username_uq" ON "operators" (lower("username"));

• Step 3: Apply the migration

NO_SUDO=1 ./scripts/db.sh migrate

Expected: Migrations applied.

• Step 4: Run drizzle/db sanity check

NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/db build

Expected: typecheck passes; new columns exposed in the generated dist.

• Step 5: Rebuild apps/web typecheck

NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/web typecheck

Expected: passes (the new optional username/passwordHash props don't break existing code).

• Step 6: Commit

git add packages/db/src/schema.ts packages/db/migrations/0010_*.sql packages/db/migrations/meta
git commit -m "feat(db): add username + password_hash to operators

Migration 0010 widens the existing operators table for username +
password auth. Backfills 'admin' on the seed row so the NOT NULL
constraint succeeds; password_hash stays nullable so the operator is
forced to set one via scripts/set-password.sh before they can sign in.
Adds a unique index on lower(username)."

Task 2: bcryptjs dependency

Files:

• Modify: apps/web/package.json

• Step 1: Add bcryptjs and its types to apps/web

NO_SUDO=1 ./scripts/dev.sh exec pnpm add -F @cmbot/web bcryptjs
NO_SUDO=1 ./scripts/dev.sh exec pnpm add -F @cmbot/web -D @types/bcryptjs

• Step 2: Add bcryptjs to packages/db (CLI scripts run from there)

NO_SUDO=1 ./scripts/dev.sh exec pnpm add -F @cmbot/db bcryptjs
NO_SUDO=1 ./scripts/dev.sh exec pnpm add -F @cmbot/db -D @types/bcryptjs

• Step 3: Verify typecheck

NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/web typecheck

Expected: passes.

• Step 4: Commit

git add apps/web/package.json packages/db/package.json pnpm-lock.yaml
git commit -m "chore: add bcryptjs to web + db packages

Pure-JS bcrypt for password hashing. Avoids the native-build pain
of node-bcrypt in our Alpine Docker images. Login is a rare event
so the perf gap is irrelevant for our scale."

 * object — both are still present on the AuthUser shape, so the
 * swap is mechanical and existing tests that mock @/lib/operator
 * keep working unchanged.

• Step 5: Run all auth helper tests

NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/web test -- --run lib/auth

Expected: PASS, 5 tests.

• Step 6: Run the full web test suite to surface fallout

NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/web test -- --run

Expected: 471 + 5 (auth) + 11 (auth-cookie) + 7 (safe-redirect) = 494, all green. If anything fails because getSeededOperator now throws when there's no session, the offending test should mock cookies + auth — patch by mocking getCurrentUser directly. Most test mocks of @/lib/operator should keep passing because they replace getSeededOperator wholesale.

• Step 7: Commit

git add apps/web/src/lib/auth.ts apps/web/src/lib/auth.test.ts apps/web/src/lib/operator.ts
git commit -m "feat(web): getCurrentUser / requireUser / requireAdmin helpers

Reads the session cookie from next/headers, verifies via auth-cookie,
loads the operators row, returns the shape every existing call site
expects (.id, .defaultTimezone, etc) plus the new .role and
.username. getSeededOperator stays as a thin compat shim that
delegates to getCurrentUser, so the ~12 tests that mock
@/lib/operator keep working without churn."

• Step 5: Run all users tests

NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/web test -- --run actions/users

Expected: PASS, 9 tests.

• Step 6: Commit

git add apps/web/src/actions/users.ts apps/web/src/actions/users.test.ts apps/web/src/app/settings/users
git commit -m "feat(web): user-management surface (admin only)

createUserAction, setUserRoleAction, resetUserPasswordAction,
deleteUserAction — all gated by requireAdmin(). Self-demote and
last-admin guards prevent the operator from accidentally locking
themselves out. /settings/users page lists every operator with
inline Demote/Promote, Reset password, and Delete buttons. 9 unit
tests."

Task 10: robots, layout meta, allowedOrigins, container hardening, rate limits, env example

Files:

• Create: apps/web/src/app/robots.ts

• Modify: apps/web/src/app/layout.tsx (export metadata.robots)

• Modify: apps/web/next.config.ts (allowedOrigins)

• Modify: docker/bot.Dockerfile

• Modify: docker/web.Dockerfile

• Modify: apps/web/src/actions/groups.ts (rate limit sendTestAction)

• Modify: apps/web/src/actions/reminders.ts (rate limits on resume/cancel)

• Create: apps/web/.env.example

• Create: packages/db/src/scripts/set-password.ts

• Create: packages/db/src/scripts/create-user.ts

• Create: scripts/set-password.sh

• Create: scripts/create-user.sh

• Step 1: Create apps/web/src/app/robots.ts

import type { MetadataRoute } from "next";

export default function robots(): MetadataRoute.Robots {
  return { rules: [{ userAgent: "*", disallow: "/" }] };
}

• Step 2: Edit apps/web/src/app/layout.tsx — add metadata.robots

Find the existing export const metadata: Metadata = { ... } block and add:

robots: { index: false, follow: false },

• Step 3: Edit apps/web/next.config.ts — add serverActions.allowedOrigins

Inside the experimental: { serverActions: { ... } } block, add a sibling property:

allowedOrigins: ["wabot.04080616.xyz", "localhost:9000"],

The block becomes:

experimental: {
  typedRoutes: true,
  serverActions: {
    allowedOrigins: ["wabot.04080616.xyz", "localhost:9000"],
    bodySizeLimit: "100mb",
  },
},

• Step 4: Add rate limit to sendTestAction in apps/web/src/actions/groups.ts

Find the sendTestAction function. After the existing await rateLimit("send-test"); call (or, if there isn't one keyed per group, add the per-group limiter after the existing IP one):

const groupRl = await checkRateLimit(`send-test:${groupId}`, { max: 3, windowSec: 60 });
if (groupRl.limited) {
  return { ok: false, error: "Too many tests for this group. Try again later." };
}

Add the checkRateLimit import at the top if missing:

import { checkRateLimit } from "@/lib/rate-limit";

• Step 5: Add rate limits to resumeReminderRunAction and cancelReminderRunAction

In apps/web/src/actions/reminders.ts, at the top of each action body add:

const ip =
  (await headers()).get("x-forwarded-for")?.split(",")[0]?.trim() ?? "unknown";
const rl = await checkRateLimit(`reminder-run:${ip}`, { max: 30, windowSec: 10 });
if (rl.limited) {
  return { ok: false, error: "Too many requests. Try again later." };
}

(headers and checkRateLimit should already be imported in this file; if not, add import { headers } from "next/headers"; and import { checkRateLimit } from "@/lib/rate-limit";.)

• Step 6: Harden docker/bot.Dockerfile

After the RUN npm install -g pnpm@9.12.0 line (or wherever the base layer ends), insert before WORKDIR /app:

RUN addgroup -g 1000 app && \
    adduser -D -u 1000 -G app -s /sbin/nologin app && \
    mkdir -p /data/sessions /data/media /app && \
    chown -R app:app /app /data && \
    chmod 700 /data/sessions
USER app

(The exact final placement is at the end of the runtime stage so dev-mode tsx can still write its .cache files into a writable HOME — set ENV HOME=/tmp if needed.)

• Step 7: Harden docker/web.Dockerfile

Same pattern at the end of the runtime stage:

RUN addgroup -g 1000 app && \
    adduser -D -u 1000 -G app -s /sbin/nologin app && \
    chown -R app:app /app
USER app

• Step 8: Create apps/web/.env.example

# Required
DATABASE_URL=postgres://user:pass@host:5432/dbname

# Auth — sign cookies. 64+ random chars. Generate via scripts/gen_auth_secret.sh.
AUTH_SECRET=replace-me

# Bump to invalidate all live sessions instantly. Leave at 1 normally.
OPERATOR_TOKEN_VERSION=1

# File-storage paths inside the bot container
DATA_DIR=/data
SESSIONS_DIR=/data/sessions
MEDIA_DIR=/data/media

# Bot fan-out tuning (see apps/bot/src/env.ts)
BOT_HEALTH_PORT=8081
BOT_LOG_LEVEL=info
BOT_FIRE_CONCURRENCY=8
BOT_GROUP_CONCURRENCY=3
BOT_MAX_SEND_PER_MINUTE=40

# Web
WEB_PORT=9000

• Step 9: Create packages/db/src/scripts/set-password.ts

import bcrypt from "bcryptjs";
import { sql } from "drizzle-orm";
import { createInterface } from "node:readline/promises";
import { Writable } from "node:stream";
import { createClient } from "../index.js";

async function main() {

  }
  const url = process.env.DATABASE_URL;
  if (!url) {
    console.error("DATABASE_URL not set");
    process.exit(2);
  }
  // Silenced password prompt.
  const muted = new Writable({ write(_chunk, _enc, cb) { cb(); } });
  const rl = createInterface({ input: process.stdin, output: muted, terminal: true });
  process.stdout.write("Password: ");
  const password = await rl.question("");
  rl.close();
  process.stdout.write("\n");
  if (password.length < 10) {
    console.error("Password must be at least 10 characters.");
    process.exit(2);
  }
  const hash = await bcrypt.hash(password, 12);
  const { db, pool } = createClient(url);
  const result = await db.execute(
    sql`UPDATE operators SET password_hash = ${hash} WHERE lower(username) = lower(${username}) RETURNING id`,
  );
  await pool.end();
  if (result.rows.length === 0) {
    console.error(`No user with username ${username}`);
    process.exit(1);
  }
  console.log("Password updated.");
  process.exit(0);
}
main().catch((e) => {
  console.error(e);
  process.exit(1);
});

import { sql } from "drizzle-orm";
import { createInterface } from "node:readline/promises";
import { Writable } from "node:stream";
import { createClient } from "../index.js";

async function main() {

  if (!username || (role !== "admin" && role !== "user")) {
    console.error("Usage: create-user <username> <admin|user>");
    process.exit(2);
  }
  const url = process.env.DATABASE_URL;
  if (!url) {
    console.error("DATABASE_URL not set");
    process.exit(2);

  const { db, pool } = createClient(url);
  await db.execute(

• Step 11: Create the shell wrappers

scripts/set-password.sh:

#!/usr/bin/env bash
set -euo pipefail
NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/db exec tsx src/scripts/set-password.ts "$@"

scripts/create-user.sh:

#!/usr/bin/env bash
set -euo pipefail
NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/db exec tsx src/scripts/create-user.ts "$@"

chmod +x scripts/set-password.sh scripts/create-user.sh

• Step 12: Bootstrap the first admin password

./scripts/set-password.sh admin

(prompt for a password ≥10 chars). Verify success message.

• Step 13: Restart web + bot, smoke-test the gate

NO_SUDO=1 docker compose --env-file .env.development -f docker-compose.base.yml -f docker-compose.dev.yml restart web bot

curl -i -s http://localhost:9000/dashboard | head -5

Expected: HTTP/1.1 307 Temporary Redirect with Location: /login?next=%2Fdashboard.

curl -i -s http://localhost:9000/api/events | head -3

Expected: HTTP/1.1 401.

curl -i -s http://localhost:9000/login | head -3

Expected: HTTP/1.1 200.

• Step 14: Run full suites

NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/web test -- --run
NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/bot test -- --run
NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/shared test -- --run

Expected: all green. Web should now sit around 471 + ~38 new tests = ~509 passing.

• Step 15: Commit the bundled hardening

git add apps/web/src/app/robots.ts apps/web/src/app/layout.tsx apps/web/next.config.ts \
        apps/web/src/actions/groups.ts apps/web/src/actions/reminders.ts \
        apps/web/.env.example \
        packages/db/src/scripts/ scripts/set-password.sh scripts/create-user.sh \
        docker/bot.Dockerfile docker/web.Dockerfile
git commit -m "feat: production hardening — robots, allowedOrigins, container non-root, rate limits, CLI bootstrap

robots.ts + metadata.robots blocks indexing.
serverActions.allowedOrigins gates cross-origin Server Action posts.
Bot + web Dockerfiles add a non-root 'app' user (uid 1000) with
chmod 700 on /data/sessions.
sendTestAction grows a per-group rate limit (3/60s).
resumeReminderRunAction + cancelReminderRunAction get a per-IP
rate limit (30/10s).
.env.example documents every required key.
packages/db/src/scripts/{set-password,create-user}.ts + thin shell
wrappers in scripts/ — first admin sets their password via
./scripts/set-password.sh admin before signing in."

Acceptance check (manual)

After all 10 tasks land:

• Smoke 1. curl -i http://localhost:9000/dashboard → 307 to /login?next=%2Fdashboard. curl -i http://localhost:9000/api/events → 401. curl -i http://localhost:9000/login → 200.

• Smoke 2. Open /login in a browser. Submit empty form → "required" error. Submit wrong password → generic "Invalid username or password" with no leak about which field was wrong.

• Smoke 3. Submit correct credentials → land on /. Reopen browser; cookie persists; refresh → still authenticated.

• Smoke 4. Bump OPERATOR_TOKEN_VERSION from 1 to 2 in .env.development and restart web. Refresh the page → redirected to /login (cookie's v no longer matches). Sign in again with the same password → land on / (new cookie issued at v=2).

• Smoke 5. As admin, visit /settings/users. Add a new user bob with role user. Sign out, sign in as bob, visit /settings/users → 401-equivalent (the page calls requireAdmin and throws).

• Smoke 6. As admin, try to demote yourself → "You can't demote your own account." Try to delete yourself → "You can't delete your own account." Promote bob to admin, then sign out as the original admin and have only one admin left; try to demote that admin from another admin's session → "Can't demote the last admin."

• Smoke 7. Visit /robots.txt directly → returns User-agent: *\nDisallow: /. View page source on /login → <meta name="robots" content="noindex, nofollow"> present.

• Smoke 8. Final test sweep:

  NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/bot test -- --run
  NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/web test -- --run
  NO_SUDO=1 ./scripts/dev.sh exec pnpm --filter @cmbot/shared test -- --run
  

  Expected: all green. ~509 web + 60 bot + 39 shared = ~608 total.
