Drop classic loldle from 8 → 6 (7-axis grid leaks too much per guess for 8 to feel earned) and emoji from 5 → 4 (3 emojis are usually unmistakable). Add a hidden /<module>_setmax <n> command per loldle module so a chat can override its own round length (1-10). Override stored at config:<subject> in each module's KV; getMaxGuesses() falls back to the default when unset.

Key Data Flows
Command Processing
Telegram update → POST /webhook → grammY secret validation
→ getBot(env) → dispatcher routes /cmd → module handler
→ handler reads/writes KV via db.getJSON/putJSON (or D1 via sql.all/run)
→ ctx.reply() → response to Telegram
Scheduled Job (Cron)
Cloudflare timer fires (e.g., "0 17 * * *")
→ scheduled(event, env, ctx) handler
→ getRegistry(env) → load + init modules
→ dispatchScheduled(event, env, ctx, registry)
→ filter matching crons by event.cron
→ for each: handler reads/writes D1 via sql.all/run (or KV via db)
→ ctx.waitUntil(promise) keeps handler alive
Deploy Pipeline
npm run deploy
→ wrangler deploy (upload to CF, set env vars and bindings)
→ npm run db:migrate (apply any new migrations to D1)
→ scripts/register.js → buildRegistry with stub KV
→ POST setWebhook + POST setMyCommands to Telegram API

Module Documentation
Each module maintains its own README.md with commands, data model, and implementation details. See src/modules/<name>/README.md.
Tests
npm test runs the full vitest suite (run in a few seconds — ~450 tests). Structure: one folder per module under tests/modules/<name>/, shared fakes under tests/fakes/ (fake-kv-namespace, fake-d1, fake-bot, fake-modules, fake-ai). No workerd, no Telegram fixtures — pure-logic unit tests with injected fakes.
