+# 心屿 Xinyu Island (`xinyu-daily`)
+
+English | [简体中文](README.zh-CN.md)
+
+A cozy daily-mood Mini App that plays like a small indie game. A floating island grows as you tell
+its keeper, a cloud named Xiaoyu, more about yourself. Each day you can draw an inspiration card,
+stick a mood sticker, drop small joys into a jar, settle indecision with a slot machine, and hunt
+for 20 hidden secrets guarded by Hengheng, a grumpy crab who calls himself the island bully. If you
+turn on Xiaoyu's companionship, Xiaoyu also writes you a letter every day, chats with you, and keeps
+a notebook of what you asked it to remember.
+
+The app makes no network requests of its own. Xiaoyu's letters and chat stay off until you turn
+them on; only then does the app run Agent turns, which send the related records to the model you
+use in MiniMax Code. The interface is in Chinese.
+
+![Xinyu Island with synthetic data](docs/preview.jpg)
+
+*Preview uses synthetic data.*
+
+## What you can do
+
+- **Today's inspiration card**: answer three light questions, then flip a collectible card with a
+  keyword, an energy score, four small stats, a colour, a number, things that suit today and things
+  to set aside. Your answers, your birthday, and what Xiaoyu knows about you change the card. Rare
+  cards are holographic. Content is generated by rules and is for fun and self-reflection only; it
+  makes no predictions and gives no advice.
+- **Mood stickers and journal**: one sticker per day, a sticker calendar, a 30-day mood curve,
+  streak medals, a card collection album, and a wall of small joys.
+- **Decision crusher**: a slot machine with a pullable lever, and a Book of Answers that gives the
+  same answer to the same question on the same day.
+- **Self-exploration**: twelve "about you" questions that grow the island (flowers, a tree, a
+  house, a lighthouse, a windmill, a rainbow) and change its weather, season, and weekend props;
+  a birthday-flower portrait; an eight-question energy-style quiz.
+- **Xiaoyu's mailbox (optional, uses your model)**: the first tap on the mailbox opens Xiaoyu's
+  invitation, which says what it would read and where that goes; nothing is sent until you accept.
+  Once it is on, Xiaoyu writes one letter a day from your recent moods and notes, small joys,
+  about-you answers, Book of Answers questions, and recent chats, so each letter follows what you
+  have shared lately. You can reply and chat (up to 20 messages a day), say "记住…" to have Xiaoyu
+  note something, review or forget every note in Xiaoyu's notebook, and get a one-line reply under
+  your mood sticker. Read letters stay in a letter box. If you decline, or the model is
+  unavailable, Xiaoyu leaves a rule-generated handwritten note instead.
+- **Care message**: when a mood note or a chat message suggests self-harm, the app shows a fixed
+  message pointing to the national mental-health hotline 12356 (and 110 / 120 for immediate
+  danger). This text is part of the app; it is not generated by the model.
+- **Exploration**: a wake-up opening, region banners, a daily journey checklist, and 20 secrets
+  hidden around the island (poke the cloud, tap the moon, squeeze a cloud, catch a shooting star,
+  and more). Each find makes Hengheng hand over a shell, tracked in a secrets log.
+- Optional synthesized sound effects (Web Audio, no audio files), day/night sky that follows the
+  clock, and `prefers-reduced-motion` support.
+
+## Install
+
+Requires MiniMax Code 3.1.2 or later, because the package declares `agentAccess`; earlier versions
+cannot install it.
+
+Copy this directory, including the hidden `.minimax-plugin/`, into the MiniMax Code plugins
+directory as `xinyu-daily/` (`~/.minimax/plugins/xinyu-daily/` by default; see the root README's
+Install section). Restart MiniMax Code, then open 心屿 from the Mini App entry in the right panel or
+ask the Agent to "打开心屿".
+
+## Tested environment
+
+- MiniMax Code 3.1.1-preview.4651 on macOS, an internal preview build that already ships the 3.1.2
+  Mini App Agent API (`context.agent`). Installed through the Host publish flow, opened in the
+  right panel. Exercised: the opening, Xiaoyu's introduction, the about-you dialogue and island
+  unlocks, daily questions and card flip, mood stickers and the 3-day streak celebration, the joy
+  jar (add and shake), the slot machine, the Book of Answers, the journal, the energy quiz,
+  discovering secrets and the secrets log, light and dark sky, and that the companion setting
+  appears when the Host provides an Agent. No console errors or failed requests.
+- Xiaoyu's companionship was exercised against a mock Agent with the same `run` contract: the
+  invitation (accept, decline, and the offline version when no Agent is available), writing and
+  opening letters, the letter box, chat with typing replies, "记住…" and forgetting notes, mood
+  replies, turning the companion off and on, a failed letter falling back to a note and "请小屿重写",
+  cancelling a turn that starts a tool, timeouts, daily limits, session reuse and replacement, and
+  the care message.
+- Not exercised end to end: Xiaoyu's companionship has not yet been run against a real model on a
+  device. Shooting stars and hot-air balloons appear at random times, the birthday cake only on the
+  user's birthday, and holographic cards only by chance. Sound output was not checked by ear.
+  Narrow layouts and reduced motion were checked by reading the CSS, not on a device.
+- The loopback checks and state recovery were exercised with a Node 22 script: requests with a
+  forged `Host` or a cross-site `Origin` get `403`, a `text/plain` write gets `415`, and no data
+  changes; a truncated, `null`, or array state file is renamed aside and the app starts empty, and
+  fields of the wrong type fall back to defaults; when a disk write fails, the in-memory state
+  stays as it was. The page's own writes, including those without a body, pass these checks in
+  headless Chrome.
+
+## Data & access
+
+- Files: reads its own files under `miniapp/client/`. Writes one file, `xinyu-state.json`, inside
+  the Host-provided `context.dataDir` (atomic write through a temporary file). If that file is
+  corrupt and cannot be read, it is renamed to `xinyu-state.broken-<time>.json` in the same
+  directory and the app starts with empty state. Nothing else.
+- Network: none from the app itself. The page only calls the app's own same-origin routes under
+  `/api/`. The server answers only requests from the local page: `Host` must be `127.0.0.1`,
+  `localhost`, or `[::1]`, and a browser `Origin`, when sent, must be this app's own address;
+  anything else gets `403`. Writes accept only `application/json`.
+- Processes: none.
+- Agent turns: declares `agentAccess: ["session.run"]` with `agentConcurrency: 1`, and runs turns
+  from the Node entry (`context.agent`) only after you turn on 小屿陪伴, in the mailbox invitation or
+  in Settings. It asks the Agent for plain text only, in three cases: today's letter (plus up to
+  eight short notes Xiaoyu keeps about you), a reply in the chat, and one line about today's mood
+  sticker. Each prompt holds the app's instructions plus your records, marked as data: today's
+  date, nickname, streak, days until your birthday (not the date itself), recent moods and notes,
+  small joys, about-you answers, energy style, today's card keyword, recent Book of Answers
+  questions, recent chat lines, the notebook, and the previous letter. Notes you forgot are never
+  sent again. Turns run in one session per day, hidden from your session list.
+- No tools, no approvals: if a turn starts a tool, asks for a permission, or asks a question, the
+  app cancels the turn and never answers `allowOnce`; Xiaoyu falls back to a handwritten note or
+  an apology line. The cancel is sent when the `tool.started` event arrives, so a very fast
+  read-only tool may already have finished by then.
+- Limits: 240 s for a letter, 120 s for a chat reply, 90 s for a mood reply; up to 20 chat
+  messages and 3 mood replies a day; one turn at a time. Agent output is checked for length and
+  format, and stripped of markup, before it is shown.
+- Turning the companion off stops new turns; a reply that was still running is discarded, and a
+  letter that was still being written is replaced by a handwritten note.
+- State stored in `xinyu-state.json`: nickname, birthday, daily mood check-ins and notes, drawn
+  cards and favourites, small joys, Book of Answers history, quiz result, about-you answers,
+  discovered secrets, one-time onboarding flags, and for the companion: the on/off choice, letters
+  (up to 60), chat lines of the last 3 days, Xiaoyu's notes, the list of forgotten notes, and
+  today's session id. The browser's `localStorage` keeps only view preferences (current tab, sky
+  mode, sound on/off, whether the opening has played).
+- Reset: Settings → 清空所有数据 deletes all stored state and cancels running Agent turns.
