 ## 4. Half-finished / fragile things
-- No leaderboard UI yet (Phase 8, but 8.1/8.2 API done — could add UI if desired).
+- No leaderboard UI yet (Phase 8 API done but no UI).
 - HP never regenerates naturally; only level-up restores it.
 - No restart-persistence test for sessions.
 - `npm run seed` script in package.json points to nonexistent `scripts/seed.js`.
 - Equipment bonuses not yet passed into combat (Issue #5 in STATUS.md).
-- Starter gear (GAME_DESIGN.md §Items) documented but not auto-created on character creation.
+- Starter gear documented but not auto-created on character creation.
 - `GET /api/zones` documented in API.md but not implemented (Issue #2).
-- Phase 9 (hardening) not started.
+- Mobile nav uses emoji icons (⚔️ 🏕️ 🎒) — verify they render acceptably on all platforms.
 
 ## 5. Decisions & deviations from the docs
 - D-004..D-007 in `docs/DECISIONS.md` (combat rounds, equipment counted once, session store, clock).
+- **D-014:** Mobile bottom nav uses emoji icons (⚔️ Hunt / 🏕️ Trip / 🎒 Items) instead of full text labels to save horizontal space on narrow screens.
+- **D-015:** Desktop tabs hidden via CSS (`display: none`) below 700px; mobile nav shown via CSS; JS `syncMobileNav()` keeps active state in sync.
 - Zod query param parsing uses `zod.coerce.number()` because Express query params are strings.
 - Inventory response uses `itemId` (item.id) and `inventoryId` (inventory row id) to avoid confusion.
 - Consumable effect parsing: regex `^(heal|energy):(\d+)$` on items.effect field.
 - Qty decrement avoids CHECK constraint violation: delete directly when qty==1, decrement when qty>1.
-- **D-008:** Shop materials with buy_price=0 sell at `floor(default_rate * character_level / item_min_level)`.
-- **D-009:** `sellItem` checks equipped_slot before material type.
-- **D-010:** `startExpedition` checks active-expedition before energy.
-- **D-011:** `computeEnergy` uses `now()` from utils/time.
+- D-008..D-013 from previous steps.
 
 ## 6. Gotchas learned
 - `npm test` must be `node --test` with NO path/glob; files must be named `*.test.js`.
-- better-sqlite3-session-store ignores `clear:false`; that's why the timer is unref'd.
+- better-sqlite3-session-store ignores `expired.clear: false`; that's why the timer is unref'd.
 - Statement caches are per-DB-handle (WeakMap) in huntService; copy that pattern for new services.
 - Verify test COUNT, not just "all passing".
 - Node.js `fetch` doesn't persist cookies across calls — extract `Set-Cookie` header and pass manually in integration tests.

 - New characters have NO inventory items (starter gear not auto-created yet).
 - Hero profile endpoint is PUBLIC — no `requireAuth` middleware.
 - Profile page is public: no auth.js guard needed; uses ?name= query param for lookup.
+- Rate limiters in tests: set `NODE_ENV=test` to get 1000 req/window limit; otherwise tests fail with 429.
+- `seed-dev.js` must check `NODE_ENV=production` before any `require()` that loads config (config throws on placeholder SECRET).
+- Express `sendFile` rejects `../` path segments — use `path.resolve()` + `path.join()` for absolute paths.
+- `express.static` sends its own 404 responses; catch-all must be placed BEFORE static middleware.
+- Character profile GET returns `{ ok: true, data: { character, derived, energy } }` — fields nested under `character`, `derived`, `energy`.
+- Register returns 201 (Created), not 200.
+- Character creation returns 201 (Created), not 200.
+- Expedition start uses `defId` in request body (not `expeditionId`).
+- Expedition claim uses `expeditionId` in request body.
+- Expedition start response returns `data.expedition.id` — capture this for claim.
+- `src/utils/time` exports `{ now, setNow, resetNow }` directly — `const time = require(...)`, not `const { time }`.
+- Inventory sell endpoint (`POST /api/shop/sell`) only accepts `material`-type items.
+- `handleListInventory` in `src/routes/inventory.js` — parameter name must be `res`, not `_res`.
 
-## 7. Next-step briefing (9.1)
-- **Goal:** Walk the SECURITY.md checklist; fix gaps.
-- **Docs:** SECURITY.md, CODING_STANDARDS.
-- Phase 9 is hardening & polish — review security, add error pages, loading states, mobile responsive pass, final playable run.
+## 7. Next-step briefing
+- **Phase 9 is complete.** All hardening and polish done.
+- **Stretch Goals available:** S1 (PvP duels), S2 (Skills/talents), S3 (Guilds), S4 (Player market), S5 (Daily rewards/quests), S6 (In-game chat), S7 (Achievements).
+- **Or address Known Issues:** Issue #2 (`GET /api/zones` missing — major), Issue #5 (equipment not in combat — minor), Issue #3 (`npm run seed` dead script — cosmetic).
+- **Recommended next step:** Fix Known Issue #2 (`GET /api/zones`) since it's a documented API gap and would improve the hunt UI. Then consider S7 (Achievements) as it's a self-contained, low-risk stretch goal that adds meaningful gameplay.

+## Quick Start
 
-## For the human
 ```bash
-cp .env.example .env
+# 1. Clone & install
+git clone <repo>
+cd Emberfall
 npm install
-npm run migrate
-npm run seed
-npm start        # http://localhost:3000
+
+# 2. Configure
+cp .env.example .env
+# Edit .env — at minimum change SESSION_SECRET to a long random string
+
+# 3. Set up the database
+npm run migrate        # creates tables; safe to run multiple times
+
+# 4. Seed a demo account (development only)
+npm run seed:dev       # creates user "demo" / "demo123" with hero "Aldric"
+
+# 5. Start the server
+npm start              # http://localhost:3000
+
+# 6. Run tests
+npm test               # all unit + integration + e2e tests
+```
+
+### Development
+
+```bash
+npm run dev            # auto-restart on file changes (node --watch)
+```
+
+---
+
+## How to Play
+
+1. **Register** a new account at `http://localhost:3000/register.html`
+   (or log in with `demo` / `demo123` if seeded).
+2. **Create a hero** — choose a class (Warrior, Mage, Rogue). Each class has
+   different base stats and bonuses.
+3. **Hunt monsters** — select a zone, spend 10 energy to fight. Victories award
+   XP, gold, and loot. Defeat costs energy but no more.
+4. **Level up** — earn XP to gain levels and stat points. Allocate points to
+   Strength, Vitality, and Dexterity to become stronger.
+5. **Equip items** — open the Inventory tab to see equipment and consumables.
+   Click to equip weapons, armor, and trinkets. Use potions to heal or restore
+   energy.
+6. **Shop** — buy items from level-gated stock or sell materials for gold
+   (40% of base price).
+7. **Expeditions** — start a timed expedition before leaving. Claim rewards
+   (XP, gold, loot) when you return after the duration elapses. Only one active
+   expedition per hero at a time.
+8. **Leaderboards** — view the top 50 heroes by level, gold, or kills.
+9. **Log out and back in** — everything persists. Your energy continues
+   regenerating while you were offline.

+## Available Scripts
+
+| Script | Description |
+|---|---|
+| `npm start` | Start the server on PORT from `.env` |
+| `npm run dev` | Start with auto-restart on file changes |
+| `npm test` | Run all unit + integration + e2e tests |
+| `npm run migrate` | Run pending migrations |
+| `npm run seed:dev` | Create demo account + hero + starter gear (skips in production) |
+
+---
+
+## Testing
+
+```bash
 npm test
 ```
-(These scripts are created by the agent in STATUS.md Phase 0.)
+
+Runs all `*.test.js` files via `node --test`. Tests use a shared SQLite file
+in `data/` (WAL mode). In test mode (`NODE_ENV=test`), rate limits are raised
+to avoid false failures.
+
+---
+
+## Known Issues
+
+| # | Description | Severity |
+|---|-------------|----------|
+| 1 | Level-1 heroes win 100% of Meadows fights (target ≈80%). Tune monster stats via a new migration. | minor |
+| 2 | `GET /api/zones` documented in API.md but not implemented. | major |
+| 3 | `npm run seed` script points to nonexistent `scripts/seed.js`. Remove or create the file. | cosmetic |
+| 4 | No test proves sessions survive a server restart. | minor |
+| 5 | Hero equipment bonuses not yet passed into combat resolution. | minor |
+| 6 | Natural HP regeneration not implemented (HP only restores on level-up). | minor |
+
+---
+
+## Architecture Notes
+
+- **Server is the only source of truth.** Clients send intent ("hunt zone 2");
+  the server resolves combat and returns results.
+- **Lazy evaluation.** Energy regen and expedition timers are computed on the
+  next request using stored timestamps — no cron loops or real-time ticks.
+- **All SQL uses prepared statements.** No string concatenation for queries.
+- **Game logic is pure functions** in `src/game/` — no DB, no Express. Fully
+  unit-testable.
