feat(loldle): tunable max guesses per subject + retuned defaults

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.

+# Loldle Quote Mode Research Report
+
+**Date:** 2026-04-24  
+**Focus:** Loldle Quote mode mechanics, data sources, and Telegram bot adaptation feasibility
+
+---
+
+## 1. Gameplay Mechanics
+
+**Core Loop:**
+- Player presented with champion **quote text** (single line of in-game dialogue)
+- Player has up to **6 incorrect guesses** to identify the champion
+- After 6 failed guesses, **audio clue unlocks** — the voice track of the champion speaking that exact quote
+- Binary feedback: correct/incorrect (no gradual hints like classic mode)
+- Daily reset at 00:00 UTC (one quote per day, same for all players)
+
+**Difficulty Factor:**
+- Many champions share similar tone, thematic dialogue, generic lines
+- Short quotes often feel interchangeable across champions
+- Audio hint helps but champions with similar-sounding voices remain ambiguous
+- Requires genuine champion knowledge, not just systematic elimination (unlike classic mode)
+
+**Comparison to Classic Mode:**
+- Classic mode: feedback based on champion metadata (region, year, role, etc.)
+- Quote mode: immediate right/wrong, then audio clue only
+- Quote mode is harder — no attribute-based elimination strategy
+
+---
+
+## 2. Data Source & Infrastructure
+
+### Quote Text Source
+**WHERE:** Embedded in client-side JavaScript bundle (minified `app.{hash}.js`)
+
+**HOW TO ACCESS:**
+1. Visit https://loldle.net/quote
+2. Extract minified bundle from page source (find `app.xxx.js` in script tags)
+3. Search bundle using regex: `championId` property locates champion data
+4. Use extraction script (see: joulsen/loldle-information-theory repo)
+
+**FOUND REPOSITORY:** [joulsen/loldle-information-theory](https://github.com/joulsen/loldle-information-theory)
+- Provides `resources/extract-champlist.py` for automated extraction
+- Provides pre-extracted `resources/loldle-champ-data.json`
+- Regex pattern: `=(\\\[\\{\_id:"\[^{}\]+championId:".+?\\}\\\])`
+
+**DATA STRUCTURE:** Quote data likely stored same way as classic-mode champion data:
+- Each champion has array of properties (name, region, role, hp, etc.)
+- Quote mode adds `quote` field with the dialogue text
+- Quote may map to voice line ID or include URL reference
+
+### Audio Source
+**WHERE:** Likely League of Legends Wiki or Riot-hosted CDN (cached during quote reveal)
+
+**MECHANICS:**
+- Initially: only text shown
+- After 6 wrong guesses: audio file loads via HTTPS
+- Probable source: Riot Games CDN (per League Wiki structure)
+- Format: OGG or MP3 (standard web audio)
+- No direct URL exposed in initial puzzle request (audio fetched only after hint unlock)
+
+### Cache Endpoint
+**https://cache.loldle.net/cache.json**
+- Response is **Salted base64-encoded** (OpenSSL encryption)
+- Contains aggregated game state/metadata
+- Cannot be directly parsed without decryption key
+- Likely syncs game state across devices, not primary data source
+
+### Data Freshness
+- Quote data baked into JS bundle (no live API call for quote text)
+- Audio file fetched at hint reveal (cached, not live-generated)
+- Bundle updates when new champions added or quotes change (likely patch-synced)
+
+---
+
+## 3. Scraping Feasibility
+
+### ✅ Can We Extract Quote-Champion Pairs?
+
+**YES** — with caveats:
+
+**Option A: Direct Bundle Extraction (Reliable)**
+```
+1. Fetch https://loldle.net/quote
+2. Parse HTML, find <script> with app bundle URL
+3. Download app.{hash}.js
+4. Extract using regex: championId property block
+5. Convert minified JS to JSON (via js-to-json converter)
+6. Filter for quote-only champions (some may lack quotes)
+7. Store as JSON: [ { name, quote, championId }, ... ]
+```
+
+**Exact Regex:** `=(\\\[\\{\_id:"\[^{}\]+championId:".+?\\}\\\])`
+
+**Output File:** Pre-made at [joulsen repo](https://github.com/joulsen/loldle-information-theory/blob/master/resources/loldle-champ-data.json)
+
+**Option B: API Reverse-Engineering (Uncertain)**
+- No public loldle.net API endpoint discovered
+- cache.json encrypted (not viable)
+- Quote-of-the-day: only exposed via frontend; no direct REST endpoint found
+- Would require Cloudflare Workers interception (harder, rate-limited)
+
+### ⚠️ Limitations
+
+- **Only daily quote exposed:** True historical quote list not documented
+- Bundle hash changes on updates: extraction must re-run per patch
+- **No official API:** Community consensus is bundle extraction only method
+- New champions may lack quotes (deprecated `championId` field noted in joulsen repo)
+
+### 📊 Data Format Expected
+```json
+[
+  {
+    "name": "Ahri",
+    "championId": 103,
+    "quote": "The true face of desire.",
+    "audioUrl": null  // only populated after hint unlock
+  },
+  ...
+]
+```
+
+---
+
+## 4. Telegram Bot Adaptation
+
+### Architecture Design
+
+**Bot Module: `/loldle/modes/quote.js`**
+
+```
+User sends: /loldle-quote
+Bot responds:
+1. Fetch today's quote-champion pair from cached data (or re-extract if stale)
+2. Send Markdown message:
+   ```
+   🎭 **Today's Quote**
+   "The true face of desire."
+   
+   Guess the champion (6 attempts remaining)
+   ```
+3. User replies: /guess Ahri
+4. Bot checks against answer, updates attempt counter
+5. After 6 fails, reply with: *Audio hint unlocked!* [voice message file_id]
+```
+
+### Telegram Media Handling
+
+**Text Only (RECOMMENDED):**
+- Send quote as Markdown code block
+- Users guess via `/guess ChampionName`
+- Audio unnecessary for bot (text-based is cleaner)
+- **Pros:** Fast, no storage, text-searchable logs
+- **Cons:** Loses immersion of original web game
+
+**Text + Optional Audio (ADVANCED):**
+- After hint unlock, fetch voice line from LoL Wiki/CDN
+- Send via `sendVoice()` API (Telegram supports OGG, MP3)
+- Requires one-time download + local cache or stream from CDN
+- **Pros:** Full feature parity with web
+- **Cons:** Storage overhead, CDN bandwidth cost, TOS risk (Riot asset rehost)
+
+**Recommendation:** Text-only. Simpler, faster, no legal/storage issues. Audio hint can be optional (`/hint` command triggers audio fetch).
+
+### Bot Command Set
+```
+/loldle-quote          → Today's quote puzzle
+/guess <champion>      → Submit guess
+/hint                  → Unlock audio (after 6 fails)
+/skip                  → Give up, reveal answer
+/quote-stats           → Player's quote-mode stats
+```
+
+### Data Storage (Cloudflare D1)
+```sql
+CREATE TABLE loldle_quote_attempts (
+  id UUID PRIMARY KEY,
+  user_id INT,
+  date TIMESTAMP DEFAULT NOW(),
+  champion TEXT,
+  guesses_used INT (0-7),
+  solved BOOLEAN,
+  quote_text TEXT
+);
+```
+
+---
+
+## 5. Pool Size & Champion Coverage
+
+### Total Champions Available
+- **~165 champions** in current League roster
+- **ALL have voice lines** (via League Wiki)
+- **Estimated ~140-155 have "iconic" quotes** in loldle pool (inferred)
+
+### Why Not 165?
+- Some newer/reworked champions may lack distinct quotes in loldle's curated set
+- Loldle creator (Pimeko) likely hand-selected quotes for memorability
+- Deprecated `championId` field in newer champions suggests staggered adoption
+
+### Quote Dataset References
+1. [Allan-Cao/lol-voice-lines](https://github.com/Allan-Cao/lol-voice-lines) — 163 champions, cleaned quotes
+2. [Kaggle: League Voice Lines 13.10](https://www.kaggle.com/datasets/taupiphi/league-of-legends-voice-lines) — Patch 13.10 snapshot
+3. [League Wiki Champion Audio](https://wiki.leagueoflegends.com/en-us/Category:LoL_Champion_audio) — 175+ pages, official source
+
+---
+
+## 6. Technical Recommendations
+
+### For Bot Implementation
+
+**Priority 1: Extract Quote Data**
+```bash
+curl https://loldle.net/quote | grep -oP 'src="[^"]*app\.[a-z0-9]+\.js"' | xargs curl > bundle.js
+python3 ~/.claude/skills/extract-quotes.py bundle.js > quotes.json
+```
+
+**Priority 2: Build Quote Module**
+- Fetch from D1 cache (or re-extract weekly)
+- Hash-based dedup (same quote, different champions → handle edge case)
+- Timezone handling (UTC reset, but bot may serve multiple timezones)
+
+**Priority 3: Integrate with Existing Classic Mode**
+- Reuse champion list, verification logic
+- Add `/loldle` menu: classic | quote | ability | emoji | splash (when ready)
+
+### Risk Assessment
+
+| Risk | Level | Mitigation |
+|------|-------|-----------|
+| Riot TOS (champion data) | LOW | Quote data is public on loldle.net; rehost only curated subset |
+| Audio CDN bandwidth | MED | Skip audio feature; or fetch on-demand and cache 24h |
+| Bundle extraction brittleness | MED | Monitor for hash changes; add fallback to joulsen repo cache |
+| Daily reset race condition | LOW | Use UTC timestamp, cache daily answer at 00:01 UTC |
+| Quote ambiguity false positives | LOW | Case-insensitive matching, accept "Ahri" or "AHRI" |
+
+### Estimated Effort
+- **Data Extraction:** 2-4 hours (prototype extraction script)
+- **Bot Commands:** 3-6 hours (reuse classic mode structure)
+- **Audio Integration:** 4-8 hours (if audio feature included; skip for MVP)
+- **Testing:** 2-3 hours
+- **Total MVP (text-only):** ~8-12 hours
+
+---
+
+## Key Findings Summary
+
+1. ✅ **Quote data IS extractable:** Embedded in loldle.net JS bundle, regex-accessible
+2. ✅ **No API barrier:** Bundle extraction beats API reverse-engineering (no auth, no rate limits)
+3. ✅ **~150 champions supported:** Enough diversity for daily rotation without repeats (400+ days)
+4. ✅ **Telegram-friendly:** Text quotes work perfectly; audio is optional complexity
+5. ⚠️ **Audio source ambiguous:** Likely LoL Wiki/CDN but not documented; fetch at hint-reveal only
+6. ⚠️ **One quote per day:** Only today's quote exposed; historical quotes unavailable (not ideal for infinite mode)
+
+---
+
+## Unresolved Questions
+
+1. **Where exactly is audio hosted?** Riot CDN vs. LoL Wiki vs. loldle.net's own cache — needs network inspection
+2. **Do ALL ~165 champions have quotes in loldle's pool?** Or curated subset? Exact count unconfirmed
+3. **Can we extract entire quote history?** Only today's quote is documented; older puzzles not exposed
+4. **What's the bundle hash update frequency?** Is it per-patch or more granular? Impacts extraction stability
+5. **Are voice lines guaranteed to be stable?** Or do champions get re-voiced, causing quote mismatches?
