 # Pigway Frame Flow

-Pigway Frame Flow is a lightweight self-hosted platform for programmable smart-frame automation.
+[简体中文](README.zh-CN.md) | English

-独立运行的智能画框服务：中英文 Web UI、深浅色模式、设备驱动抽象、KoKonna 全部已公开接口、图片处理、模板、SQLite 调度与播放列表、临时覆盖恢复和 REST API。
+Pigway Frame Flow is a lightweight, self-hosted platform for programmable smart-frame automation. It runs independently on a NAS or server, with its own Web UI, image library, rendering, scheduler and REST API. KoKonna is a supported device integration; external applications do not need its credentials or SDK.

-KoKonna is a supported device integration and is not affiliated with this project unless otherwise stated.
+### Installation

-## Quick Start / 快速开始
+Deploy with Docker Compose. The current default configuration and verified platform are AMD64:

-```sh
-python3 -m venv .venv
-.venv/bin/python -m pip install -r requirements.lock
-.venv/bin/python scripts/run_local.py
-```
-
-Open http://127.0.0.1:18787. The local demo creates a private `.env` with a random
-FRAME_FLOW_TOKEN. Read that token locally in an editor and enter it on the login
-screen. Do not paste a KoKonna API Key into Web UI. Demo always forces mock mode
-and disables real writes. It leaves data persistent in ./data and ./config.
-
-网页使用账号密码登录。通过 `python scripts/create-account.py --username YOUR_NAME` 创建账号，再启动服务；密码不会写入代码或明文配置。勾选记住登录可保持 30 天，设置页面可修改密码或退出。
-
-## Architecture / 架构
-
-```
-providers → templates / renderers → generated image
-                                  ↓
-Web UI / external REST → DisplayService → FrameDeviceDriver → KokonnaDriver
-Scheduler / Playlist ─────────────┘
-                   SQLite: operations / history / jobs / overrides / assets
-```
-
-Package: pigway_frame_flow. Device composition is in core/registry.py;
-vendor-specific code is in drivers/kokonna. One process, one worker, no Redis,
-message broker, OpenClaw, Home Assistant or external application dependency.
-
-## Configuration / 配置
-
-Copy `.env.example` to `.env`, set a strong FRAME_FLOW_TOKEN, chmod 600 .env.
- KOKONNA_MOCK=true: independent persistent demo, no cloud calls.
- KOKONNA_WRITE_ENABLED=false: live write protection, mandatory before verification.
- KOKONNA_API_KEY: device key, never stored in DB or returned to Web UI.
- *_FILE: optional Docker Secret equivalent.
- WEB_BIND/WEB_PORT: Compose host bind and port. Internal app binds container network.
- CORS_ALLOWED_ORIGINS: exact comma-separated origins; default empty.
- IMAGE_URL_ALLOWED_HOSTS: exact public HTTPS hosts; default disabled. Redirects denied.
- TZ=Asia/Shanghai; DATA_DIR=/data; CONFIG_DIR=/config.
-
-For multiple devices copy deploy/devices.yml.example into config/devices.yml,
-reference a separate environment key per device. Jobs bind a device_id. Layout
-currently targets 1200 × 1600; incompatible geometry is refused before writes.
-
-## Docker
-
-```sh
+```bash
 cp .env.example .env
-# Configure a token; keep API key empty, mock true, writes false.
+# Set a strong FRAME_FLOW_TOKEN; keep mock=true and writes=false initially.
+chmod 600 .env
 mkdir -p data/images data/generated data/cache config
 sudo chown -R 10333:10333 data config
 ./scripts/build-verify.sh
+# Create the browser administrator account; enter its password interactively.
+docker compose run --rm --no-deps -e PYTHONPATH=/app \
+  -v "$PWD/scripts:/bootstrap:ro" --entrypoint python pigway-frame-flow \
+  /bootstrap/create-account.py --username admin --config-dir /config
 docker compose up -d
-python3 scripts/smoke-test.py
 ```

-Image pigway-frame-flow:latest, service/container pigway-frame-flow, AMD64,
-Python 3.14.5, pinned runtime dependencies, CJK fonts, non-root UID/GID 10333,
-read-only root filesystem, writable /data and /config, no capabilities, no host
-network, no Docker socket. Restart unless-stopped. JSON-file logs capped 10m × 3.
-Healthcheck uses service /health, not cloud availability. No second log database.
+Open `http://127.0.0.1:18787` and sign in with the account you created. The browser uses an HttpOnly session cookie; it does not require an API token. Remembered sessions last 30 days. Change the password or sign out in Settings. `FRAME_FLOW_TOKEN` authenticates external API clients and is separate from the KoKonna API key.

-## Synology NAS
+The published interface defaults to loopback. For LAN access, explicitly set `WEB_BIND` to your NAS LAN address and choose an available `WEB_PORT`. See [Synology deployment](docs/NAS.md), [build mirrors and caching](docs/BUILDING.md), and [Gitea deployment/rollback](docs/deployment/GITEA_CD.md). No firewall, router or reverse-proxy settings are changed automatically.

-Target `/volume2/docker/pigway-frame-flow/`. See [NAS deployment](docs/NAS.md).
-Set WEB_BIND to the NAS LAN IP to restrict the published interface, or explicitly
-0.0.0.0 when desired. Port 18787 must be free. No router/firewall/reverse proxy
-rules are modified. Source and persistent volumes stay in this project directory.
-No artificial logs directory is required. Compose creates its own bridge network.
+For a local mock demo, use Python 3.14:

-## KoKonna Setup / 真实设备
+```bash
+python3.14 -m venv .venv
+.venv/bin/python -m pip install -r requirements.lock
+.venv/bin/python scripts/create-account.py --username admin
+.venv/bin/python scripts/run_local.py
+```

-First deploy Mock and verify persistence. Then set KOKONNA_MOCK=false and fill
-KOKONNA_API_KEY through private environment/secret. Keep writes false. /ready checks
-configuration/DB/worker/token without a cloud call. Query device and images metadata;
-compare model, geometry, timezone, heartbeat, battery, imageId, coverId, sync.
-If different, stop and report. **Do not enable writes or perform the single test
-until the owner explicitly authorizes it.** Test design: [REAL_DEVICE_TEST.md](docs/REAL_DEVICE_TEST.md).
+The demo forces mock mode and disables device writes. Data and configuration remain in `data/` and `config/` across restarts.

-## Security
+### Features and boundaries

-Protected /api/v1 capabilities accept an administrator account session, or external
-Frame Flow Bearer auth with scope checks.
-SQLite stores token hashes. Device keys live only in env/secret and runtime memory.
-Browser login uses SQLite accounts with salted scrypt password hashes and revocable,
-HttpOnly/SameSite=Strict cookies (30 days when remembered, 12 hours otherwise).
-Mutations require a session CSRF header. Logout and password changes revoke sessions.
-Passwords and browser sessions are never stored in localStorage. Bootstrap hashes
-in private `config/accounts.json` seed new accounts only; restarting does not undo
-a password change. Five failed logins per source IP cause a five-minute lockout.
-The browser needs no API Token. Bearer authentication remains compatible for
-external clients; the KoKonna key is never used for account login.
-The LAN deployment uses HTTP; use an explicitly configured HTTPS endpoint if
-transport encryption is needed. No reverse proxy or firewall is changed automatically.
+- Chinese and English Web UI, light/dark themes, account login, device dashboard and image previews.
+- Local staging and KoKonna cloud gallery, uploads, image switching, stars, source/task filters and batch actions.
+- Aspect-ratio-preserving contain/cover/smart conversion, color/grayscale profiles and orientation selection for photo sources.
+- Seven templates: Daily Dashboard, Weather, Calendar, Quote, Photo + Text, Daily Poetry and System Alert.
+- Layout Studio for collages/posters with 1–12 images; optional OpenAI-compatible layout planning and source-driven automatic collages.
+- Device-bound schedules, ordered/random playlists, temporary priority overrides, restore and persistent operation history.
+- Read-only NAS folders, Synology Photos person filtering, WebDAV and optional cloud-drive connectors. Each source has its own configuration and authorization.
+- Optional weather, calendar, monitoring, AI, MQTT and webhook integrations. Provider configuration is required; an unconnected provider is not a working connection.

-## API
+Templates **render images**, including text-only templates. Choose a template, edit its data, generate a preview, then display it. Preview generation and saving template settings do not update the frame. Photo + Text and Daily Dashboard can include a selected local photo; other templates do not automatically choose one. Scheduled template jobs render afresh on each run. See [photo sources](docs/PHOTO_SOURCES.md), [automatic collages](docs/AUTOMATIC_COLLAGE.md) and [integration setup/limits](docs/EXTENSIONS.md).

-OpenAPI 3.x at /openapi.json; Swagger at /docs; stable /api/v1. Display/render/upload
-return 202 + operation_id. Poll /api/v1/operations/{id}; completion requires matching
-image ID and cloud synced flag. Idempotency-Key retained seven days. X-Request-ID
-traces history. UNKNOWN writes block later mutations; read-only reconciliation
-and explicit admin acknowledgement release the block, never replay a write.
-The older /api/display route is retained and deprecated (same v1 payload).
-See [external integration contract](docs/integrations/TICKTAR.md).
+Real weather uses the configured provider/location and is refreshed when rendered; it does not update an already displayed image by itself. Official KoKonna widgets are separate from Frame Flow templates and require optional vendor-account authorization. API-key access remains independent.

-## Scheduler / Playback
+### Device integration and API

-Cron (5 fields), daily, weekdays, weekends, date and temporary tasks; Shanghai time.
-Use source {"type":"restore"} for explicit restore jobs. Unique job/slot and persistent
-idempotency prevent duplicate dispatch. Overdue tasks >5 minutes are skipped rather
-than unexpectedly overwriting artwork after downtime. State persists across restart.
-Overrides use priority then recency; lower priorities wait without uploading.
-If another app changes the frame, expired overrides do not overwrite its artwork.
-Frame Flow playlists support ordered/random cloud image IDs and >=5-minute intervals;
-only one enabled playlist per device. They pause for overrides/unknown writes.
-Native cloud slideshow mode/interval are readable; membership/editing are unavailable
-in the official API. Avoid having native and Frame Flow playback compete.
+```text
+Providers → Templates / Renderers → Generated image
+Web UI / Scheduler / REST API → DisplayService → FrameDeviceDriver → KoKonna
+                                      ↓
+                     SQLite: jobs, operations, history, overrides, assets
+```

-## Templates / 图片
+Configure the device key privately through `.env` or a secret file. Start with `KOKONNA_MOCK=true` and `KOKONNA_WRITE_ENABLED=false`; after mock verification, connect read-only before explicitly enabling writes. Multi-device definitions use `config/devices.yml` and device-specific key references. Vendor code stays in `drivers/kokonna`; other applications use the same service API as the Web UI.

-Seven JSON layout templates: daily-dashboard, weather, calendar, quote, photo-text,
-daily-poetry and system-alert, with color and grayscale profiles. Every template
-renders an image, including templates that contain only text.
+The public API is `/api/v1`, with OpenAPI at `/openapi.json` and Swagger UI at `/docs`. Display/render/upload operations return HTTP 202 and an operation ID; poll `/api/v1/operations/{id}` for the outcome. `Idempotency-Key` prevents duplicate dispatch, and `X-Request-ID` links requests to history. An uncertain write blocks subsequent mutations until read-only reconciliation or explicit administrator acknowledgement; it is never automatically replayed.

-使用流程：选择模板 → 编辑数据 → 生成预览 → 显示到画框。生成预览只创建本地图片；
-保存默认数据只保存配置，两者都不会更新设备。自动化模板任务每次运行重新生成图片。
+Ticktar integration is optional. Frame Flow has no runtime dependency on Ticktar and never accesses its database. See the [external integration contract](docs/integrations/TICKTAR.md).

- **照片与文字 / Photo + Text**：标题、中央照片区域、下方正文；与照片数据源任务的底部水印布局不同。
- **家庭早报 / Daily Dashboard**：日期、天气、事项、一句话与所选照片区域。
- **天气 / Weather**：当前天气与三天预报；天气 JSON 留空时使用配置的 Provider。
- **日历、每日诗词、一句话、系统告警**：将相应信息排版为图片，不自动选择图库照片。
+### Storage and security

-Photos use a local asset ID (`photo_id`); without a selected photo, a placeholder
-is rendered. Configure Open-Meteo and location coordinates in **Settings → Weather
-source** for real weather. Forecasts are fetched on demand and cached for ten minutes;
-unavailable/stale data is labeled explicitly. Weather remains static on the frame
-until the next render and display, so use an Automation job for regular updates.
-Official KoKonna widgets are a separate integration, not these local templates.
-No unreliable lunar date is fabricated.
-Contain preserves composition with margins; cover crops centrally; smart is an
-edge-saliency heuristic. Always inspect preview; face-aware guarantees are not claimed.
-Cloud uploads activate immediately, so gallery-only means **local staging**.
+Docker persists `/data/frameflow.db`, images/generated/cache under `/data`, and private configuration/session files under `/config`. It runs as UID/GID 10333 with a read-only root filesystem, its own bridge network, `unless-stopped` restart policy and bounded stdout/stderr logs. No privileged mode, host network or Docker socket is required.

-## Development / Testing
+Passwords are hashed; browser mutations require CSRF protection. API keys and provider credentials stay server-side and must never enter Git or logs. CORS is disabled unless origins are explicitly configured. `/health` checks the service; `/ready` checks local dependencies without making cloud availability a restart trigger. See [public repository privacy](docs/PUBLICATION.md), [LICENSE](LICENSE) and [NOTICE](NOTICE.md).

-Tests mock every cloud request; no real-device writes. scripts/ui-smoke.cjs runs an
-isolated headless browser and checks settings.mock before acting. CI builds AMD64,
-validates Compose, starts a container, checks health/ready and restarts for persistence.
+Tests mock cloud/device calls. CI also verifies an isolated Docker build, readiness, smoke tests, restart and cleanup. External fork PRs do not execute on the production-capable NAS runner.

-## Known Limitations / 已知边界
+Cloud synchronization does not prove the physical pixels refreshed. KoKonna cloud uploads activate immediately, so upload-only uses local staging. Native slideshow membership editing is unavailable; avoid running native and Frame Flow playback simultaneously. Smart cropping is a saliency heuristic, not guaranteed face detection. The service uses one worker and is not designed for multiple replicas. Browser OAuth, AI daily-art scheduling, additional calendar recurrence features and more device drivers remain roadmap items.

-Cloud acknowledgements do not prove physical display pixels. Model fields may be
-omitted and are explicitly marked configured. No native slideshow membership API,
-no cloud upload-only API, no automatic retries after uncertain writes. Opt-in local retention protects manual uploads, stars and active references; its quota is a cleanup target, not a hard disk limit. Rendering assets are local, limited
-to 25M pixels/20 MiB. This release uses a single worker and is not multi-replica.
-Gallery reads have no pagination because upstream documents none. Web UI hides
-secrets and lazy-loads thumbnails; generating a first thumbnail fetches one original.
-Scoped client provisioning and bounded signed webhook delivery are available in Connections. Docker build/NAS
-status is recorded honestly in docs/ACCEPTANCE.md.
-
-## Roadmap
-
-Browser OAuth login, AI daily-art scheduling, custom ICS timezones/EXRULE and additional hardware-specific adapters remain pending. MQTT, bounded recurrence, token refresh, transition events and single-image AI generation are optional capabilities. See [optional capabilities and exact limits](docs/EXTENSIONS.md).
-
-## Layout Studio and optional integrations
-
-Bilingual Layout Studio imports 1–12 images, edits bounded regions and renders a collage or poster. Optional OpenAI-compatible AI plans receive text and dimensions only. Connections configures provider credentials, calendars/state, retention, client scopes and webhooks. Photo Sources includes NAS, WebDAV, Google Drive, AliPan and Baidu readers. Authorization is separate from implementation; unconnected providers return explicit errors. See [setup and limitations](docs/EXTENSIONS.md).
-
-## Template editing
-
-Templates provide bilingual form fields, event lists, local photo selection, advanced
-JSON, color/grayscale previews, persistent defaults and reset to built-in defaults.
-Changing content invalidates the previous preview. Weather uses the labeled Mock
-provider until a real provider is configured. Live display controls stay disabled
-until real writes are separately approved.
-
-Browser smoke tests use a disposable Mock account via FRAME_FLOW_TEST_USERNAME
-and FRAME_FLOW_TEST_PASSWORD; never run the mutation smoke suite against live devices.
-
-## Current content and completed page workflows
-
-Dashboard displays the actual current image and recorded content source. Frame Flow
-stores immutable template/data/profile snapshots when it renders an asset and maps
-successful upload results to the device/image ID. The current-content endpoint
-matches the live device image ID; vendor images with no recorded source remain
-explicitly unknown. Switching externally never makes the previous template appear
-as the current one. Restore also restores the matching content provenance.
-
-Templates can load the current recorded template or continue editing a generated
-local image. They support direct photo import and protected image downloads.
-Gallery provides search, sorting, dimensions and downloads. Display confirmation
-supports duration, priority and restoration. History includes operation details.
-Automation offers content pickers, template profiles, previews and manual execution;
-playlists offer gallery image checkboxes. Real writes remain blocked by the server
-regardless of the UI controls.
-
-Settings persists weather coordinates/provider and image URL host allowlists in
-SQLite. Open-Meteo provides current model weather and a three-day forecast, cached
-for ten minutes on demand. Network failures show unavailable/stale data and use a
-two-minute backoff, without replacing it with fictitious live data. Default remains
-Mock until configured in Settings. Open-Meteo attribution is included in the UI and
-weather/dashboard renders. Image URL import is HTTPS-only with explicit hostnames,
-public-address validation and pinned DNS; redirects and private addresses are blocked.
-
-Additional v1 endpoints: `/devices/{id}/current-content`, `/assets/{id}/source`,
-`/providers/weather`, `/settings/weather`, `/settings/image-url`, `/jobs/{id}`,
-`/jobs/{id}/preview`, `/jobs/{id}/run` (all under `/api/v1`). Existing contracts remain
-compatible; new endpoints are included in generated OpenAPI and contract tests.
-
-## Daily Poetry / 每日诗词
-
-The daily-poetry template includes 20 public-domain classical Chinese poems, selected deterministically by Shanghai date, or manually. Create a daily job from its editor; new poetry jobs are paused by default until you enable them. Custom title, author and verses are editable. This is an independent Frame Flow content provider, not the KoKonna mini-program subscription. Official public API does not expose mini-program subscription/template settings.
-
-每日诗词支持按上海日期选诗、手选 20 首古典诗词、自定义文本以及每日任务。模板显示操作使用统一上传/显示服务；真实写入须开启 KOKONNA_WRITE_ENABLED，结果未知不会自动重试。官方小程序原有每日诗词订阅不能通过当前公开 API 查询或修改。
-
-
-### 官方账号连接 / Official account connection
-
-在 Templates → 官方小组件中，由管理员输入 KoKonna 官方账号和密码，查询账号下
-的设备后手动关联当前 Frame Flow 设备。此流程不绑定或解绑云端设备，也不改变
-图片或订阅。现有 API Key 接入继续负责设备、图库和显示能力。
-
-密码不保存；会话与关联信息保存在 `/config/official-{device_id}.secret`，权限 0600。
-容器重启可恢复连接。会话过期需要重新登录；断开连接会清除本地会话，不撤销
-官方服务器上的其他登录。局域网访问沿用现有部署方式。
-
-Official account connection is admin-only and separate from API Key access.
-Login, device discovery, local association and disconnect are available through
-`/api/v1/devices/{device_id}/official/connection`. Passwords are never persisted;
-server-side sessions are stored as restricted secret files. No official widget
-mutation or other extra RPC write is enabled by connecting.
-
-### Photo sources / 照片数据源
-
-Gallery supports read-only NAS folders and HTTPS WebDAV sources, random photo
-preview, and device-bound scheduled random photos. Source definitions are persisted
-in SQLite. See [setup and limits](docs/PHOTO_SOURCES.md).
-NAS 本地目录需要显式只读挂载；网盘先支持通用 WebDAV，也可使用同步到 NAS 的目录。
-
-### Build networking and cache
-
-The Dockerfile retains the pinned Python base, locked Python dependencies,
-`fonts-noto-cjk`, Debian repository signature checks, and offline artifact
-SHA256 verification. Both production and CI use `scripts/build-verify.sh`,
-which enables BuildKit and retains `docker compose build --pull`.
-
-APT mirror hosts are configurable through `DEBIAN_MIRROR` and
-`DEBIAN_SECURITY_MIRROR` (hosts only, without scheme or path). Defaults are
-`deb.debian.org`; HTTPS is used for both Debian and security repositories.
-For mainland-China NAS builds, use the shared profile:
-
-```sh
-. ./deploy/build-cn.env
-./scripts/build-verify.sh
-```
-
-CI loads this same profile, using Tsinghua TUNA for both repositories unless
-Gitea repository variables `DEBIAN_MIRROR` / `DEBIAN_SECURITY_MIRROR` override
-it. Production may also set the two hosts directly in `.env` when calling the
-build script without the profile. An alternate mainland mirror is
-`mirrors.ustc.edu.cn`; availability and throughput depend on the Runner network.
-No fallback disables signature verification or removes packages.
-
-Layer order stays: pinned base → APT/font dependencies → `requirements.lock`
-→ pip dependencies → application/vendor source → build metadata.
-A source-only change therefore reuses the APT and pip layers, provided the
-same builder, base digest, mirror arguments, and optional offline artifacts
-are used. Changing the lockfile rebuilds pip and later layers, not APT.
-Changing the mirror or APT instructions rebuilds APT and later layers.
-
-Previously an APT layer miss redownloaded indexes/packages, and pip used
-`--no-cache-dir`. Now locked BuildKit mounts retain APT indexes, downloaded
-`.deb` files, and pip downloads/wheels outside the final image. Debian's
-`docker-clean` hook is disabled so it cannot discard cached packages.
-Re-executed APT steps still run `apt-get update` and validate repository
-signatures; cached packages and pip artifacts can avoid repeat large downloads.
-The initial build after this Dockerfile change will miss dependency layers;
-subsequent builds benefit. No measured speedup is claimed before CI completes.
-
-Caches belong to the Docker builder, not the ephemeral CI workspace. Keep the
-NAS Runner's builder storage across jobs; removing the builder, pruning caches,
-or using a fresh Docker daemon loses the benefit. Cache mounts are disposable:
-an empty cache still builds correctly. `--pull` remains enabled; a pinned base
-digest check alone does not invalidate dependency layers. To deliberately
-refresh installed APT versions, use `docker compose build --pull --no-cache`.
-
-### CI with a host Docker socket
-
-Run `python scripts/ci-compose-verify.py` after loading the build mirror profile.
-The script derives a temporary Compose document from production settings, with
-an absolute client-side build context, a UUID project name, a unique CI image
-tag, and project-scoped `data` / `config` named volumes. It removes production
-bind mounts, the fixed container name, host ports, and the production `.env`
-reference. A fresh test token, mock driver, and disabled device writes are
-explicitly configured. Docker initializes empty named volumes from the image's
-owned `/data` and `/config` directories; the service remains UID/GID 10333.
-
-Build contexts are sent by the Docker client, so the job workspace can remain
-inside the job container. Runtime storage is managed by the daemon; no matching
-NAS host `/workspace` directory is needed. HTTP readiness and the unmodified
-nine-endpoint smoke script run inside the service with `compose exec -T`.
-Restart is followed by another readiness check and the same smoke test.
-
-A `finally` block removes the test containers, network, volumes, and unique
-image tag on success or failure. The workflow records the private temporary
-Compose path in `GITHUB_ENV` and repeats cleanup in an `always()` step, covering
-normal cancellation/interruption. Failed cleanup retains the manifest so the
-fallback can retry. Abrupt host/daemon loss or a forcibly terminated entire job
-can prevent both cleanup paths; no CI script can guarantee cleanup in that case.
-No global prune or production resource removal is performed. Keep builder
-caches: only the run-specific image tag is removed.
-
-### CI Job pip indexes versus Docker build indexes
-
-The Job bootstrap runs `python scripts/ci-install.py` before Ruff/mypy/tests.
-It needs only the Python standard library, so it runs before PyYAML or tooling
-is installed. `CI_PIP_INDEX_URL` and `CI_PIP_FALLBACK_INDEX_URL` are optional
-Gitea repository variables. Defaults are the TUNA HTTPS PyPI simple endpoint
-and official `https://pypi.org/simple`. Each is attempted separately; the
-fallback repeats the unchanged editable `.[test]` installation, including
-PEP 517 build isolation and `setuptools>=75`. No simultaneous extra index is
-used, no build dependency is removed, and both failures fail CI.
-
-Logs show inherited index/config/proxy hosts and the selected index host for
-each attempt, with URL credentials and query strings removed. Bootstrap
-disables inherited pip config files via `PIP_CONFIG_FILE=/dev/null`, explicitly
-sets the selected index, and clears no-index/extra-index/find-links, insecure
-trusted-host, and no-build-isolation environment settings. Constraints, TLS
-certificate environment settings, and proxy settings remain in effect.
-
-These `CI_PIP_*` settings apply only to the Job's pip install. They are not
-passed into Docker build arguments or persisted into the production image.
-The Dockerfile keeps its own cached/offline dependency installation and logs
-the Docker pip index host for online installs. Debian mirror variables affect
-APT only and are loaded later in the Docker verification step.
-
-If dependency installation fails, the always() cleanup step still executes.
-It skips the Python/PyYAML cleanup script when no CI Compose manifest exists,
-as no Docker verification resources have been created at that point.

+# Pigway Frame Flow
+
+简体中文 | [English](README.md)
+
+轻量、自托管的智能画框自动化平台，可独立运行在 NAS 或服务器上，提供自己的 Web 界面、图库、图片渲染、调度器和 REST API。KoKonna 是支持的设备集成之一；外部应用无需持有它的凭据或引入其 SDK。
+
+### 安装
+
+使用 Docker Compose 部署。当前默认配置与已验证平台为 AMD64：
+
+```bash
+cp .env.example .env
+# 设置强 FRAME_FLOW_TOKEN；首次保持 mock=true、writes=false。
+chmod 600 .env
+mkdir -p data/images data/generated data/cache config
+sudo chown -R 10333:10333 data config
+./scripts/build-verify.sh
+# 创建网页管理员账号，密码通过交互输入。
+docker compose run --rm --no-deps -e PYTHONPATH=/app \
+  -v "$PWD/scripts:/bootstrap:ro" --entrypoint python pigway-frame-flow \
+  /bootstrap/create-account.py --username admin --config-dir /config
+docker compose up -d
+```
+
+打开 `http://127.0.0.1:18787`，使用刚创建的账号登录。网页使用 HttpOnly 会话 Cookie，无需输入 API Token；勾选记住登录后会话有效期为 30 天，可在设置中修改密码或退出。`FRAME_FLOW_TOKEN` 用于外部 API 客户端鉴权，与 KoKonna API Key 分开。
+
+默认端口只绑定本机回环地址。需要局域网访问时，显式将 `WEB_BIND` 设置为 NAS 的局域网地址，并通过 `WEB_PORT` 选择空闲端口。参见[群晖部署](docs/NAS.md)、[构建镜像源与缓存](docs/BUILDING.md)和 [Gitea 部署与回滚](docs/deployment/GITEA_CD.md)。不会自动修改防火墙、路由器或反向代理。
+
+使用 Python 3.14 运行本地 Mock 演示：
+
+```bash
+python3.14 -m venv .venv
+.venv/bin/python -m pip install -r requirements.lock
+.venv/bin/python scripts/create-account.py --username admin
+.venv/bin/python scripts/run_local.py
+```
+
+演示强制使用 Mock，并关闭设备写入。数据与配置保存在 `data/`、`config/`，重启后保留。
+
+### 功能与边界
+
+- 中英文 Web 界面、深浅色主题、账号登录、设备面板与图片预览。
+- 本地暂存和 KoKonna 云端图库，上传、切换、星标、来源/任务筛选及批量操作。
+- 保持比例的 contain/cover/smart 图片转换，彩色/灰度模式与照片数据源的横竖方向选择。
+- 七种模板：家庭早报、天气、日历、一句话、照片与文字、每日诗词、系统告警。
+- 拼图工作室支持 1–12 张图片的拼图与海报；可选 OpenAI 兼容接口排版，以及从数据源自动选图拼接。
+- 绑定设备的定时任务、顺序/随机播放列表、带优先级的临时覆盖、恢复与持久化操作历史。
+- 只读 NAS 文件夹、Synology Photos 人物筛选、WebDAV 和可选网盘连接器；每个数据源独立配置、独立授权。
+- 可选天气、日历、监控、AI、MQTT 与 Webhook 集成。需要配置对应 Provider；尚未授权的数据源不会被当作已连接。
+
+模板会**生成图片**，纯文字模板也是如此。使用顺序是：选择模板 → 编辑内容 → 生成预览 → 显示到画框。生成预览和保存模板设置都不会更新画框。“照片与文字”和“家庭早报”可以包含指定的本地照片，其他模板不会自动选图；定时模板任务每次运行会重新渲染。参见[照片数据源](docs/PHOTO_SOURCES.md)、[自动拼图](docs/AUTOMATIC_COLLAGE.md)和[集成配置及限制](docs/EXTENSIONS.md)。
+
+天气使用配置的服务和地点，在渲染时更新，不会自行刷新已显示的图片。KoKonna 官方小组件与 Frame Flow 模板是两项独立能力；使用官方小组件需要额外授权厂商账号，API Key 接入仍可单独使用。
+
+### 设备集成与 API
+
+```text
+Provider → 模板 / Renderer → 生成图片
+Web UI / Scheduler / REST API → DisplayService → FrameDeviceDriver → KoKonna
+                                      ↓
+                       SQLite：任务、操作、历史、覆盖状态、图片
+```
+
+设备 Key 通过私有 `.env` 或 Secret 文件配置。首次保持 `KOKONNA_MOCK=true`、`KOKONNA_WRITE_ENABLED=false`，Mock 验证后先只读连接，再明确开启写入。多设备使用 `config/devices.yml` 配置，每台设备引用自己的 Key。厂商代码位于 `drivers/kokonna`；Web 界面与外部程序使用相同业务服务。
+
+正式 API 为 `/api/v1`，OpenAPI 位于 `/openapi.json`，Swagger 位于 `/docs`。显示、渲染、上传返回 HTTP 202 和操作 ID，通过 `/api/v1/operations/{id}` 查询结果。`Idempotency-Key` 防止重复派发，`X-Request-ID` 串联请求与历史。写入结果不确定时会阻止后续修改，必须只读核对或由管理员明确确认，不会自动重放写请求。
+
+Ticktar 集成为可选项，Frame Flow 不依赖 Ticktar 启动，也不访问其数据库。参见[外部集成契约](docs/integrations/TICKTAR.md)。
+
+### 存储与安全
+
+Docker 持久化 `/data/frameflow.db`、`/data` 下的图片/生成文件/缓存，以及 `/config` 下的私有配置和会话文件。容器以 UID/GID 10333 运行，根文件系统只读，使用独立桥接网络、`unless-stopped` 重启策略和有大小限制的标准输出日志；不需要 privileged、host network 或 Docker socket。
+
+账号密码保存为哈希，网页修改操作有 CSRF 校验。API Key 和 Provider 凭据仅留在服务端，不得提交 Git 或写入日志。CORS 默认不开启，需明确配置来源。`/health` 检查服务自身，`/ready` 检查本地依赖，不以云端可用性触发重启。参见[公开仓库隐私](docs/PUBLICATION.md)、[LICENSE](LICENSE) 和 [NOTICE](NOTICE.md)。
+
+KoKonna 是支持的设备集成。本项目与 KoKonna 无隶属关系，也不代表其官方认可。
+
+### 开发与已知限制
+
+```bash
+.venv/bin/python -m pip install -e '.[test]'
+.venv/bin/python -m ruff check pigway_frame_flow tests scripts
+.venv/bin/python -m ruff format --check pigway_frame_flow tests scripts
+.venv/bin/python -m mypy pigway_frame_flow
+.venv/bin/python -m pytest -q
+.venv/bin/python -m pip_audit -r requirements.lock --no-deps --disable-pip
+```
+
+测试使用 Mock 云端/设备调用；CI 还验证隔离的 Docker 构建、就绪检查、smoke test、重启与清理。外部 Fork PR 不会在可访问生产环境的 NAS Runner 上执行。
+
+云端同步不等于已确认物理屏幕刷新。KoKonna 云端上传会立即切换，因此“仅上传”使用本地暂存。官方接口不支持编辑原生轮播成员，应避免原生轮播与 Frame Flow 播放同时运行。smart 裁切采用显著性启发式，不保证识别人脸。当前服务使用单 Worker，不面向多副本部署。浏览器 OAuth、AI 每日艺术调度、更多日历重复规则及设备驱动仍属于后续计划。

+
+在「拼图」选择照片来源与数量（1–12），填写可选标题或排版要求，点击
+「随机选图并生成预览」。默认使用启用的数据源；没有数据源时使用本地上传照片。
+AI 只接收图片尺寸、内部资产 ID 和排版文字，不发送照片。

+layout instructions are sent to AI. AI configuration/errors are explicit; uncheck
+AI for deterministic grid layout. Preview never changes the frame. Canvas
+orientation follows the target device. Manual layout is under Advanced.
+
+「创建自动化任务」保存来源和数量，而不是固定图片列表。任务初始暂停，
+请在自动化中编辑执行时间后启用。每次运行重新随机选图，但不同运行之间可能重复；
+单次不重复选同一照片。照片不足时失败，不重复图片凑数。
+NAS 来源继续使用人物、方向与质量筛选；一次最多检查数量的五倍候选图片。

+定时拼图沿用云库每任务保留最近一张成功图的策略，下一张确认成功前不删除上一张。

+Create automation stores the source/count, initially paused. Edit its schedule
+and enable it. Each execution selects new candidates; repeats across executions
+are possible. Too few usable photos fails before upload. Existing unknown-write,
+restoration and cloud-retention safeguards apply.
+
+## Public API
+
+`POST /api/v1/render` accepts this additive content type, returning HTTP 202 and
+an operation ID. `POST /api/v1/display` uses the same content inside its existing

+  "use_ai": true,
+  "prompt": "Feature one photo with smaller supporting photos",
+  "profile": "color"
+}
+```
+
+`source_id: null` chooses local uploaded assets (generated and cache images are
+excluded). AI configuration is shared with existing Layout Studio. No new API key
+or vendor dependency is introduced. The OpenAPI contract test records the new
+content schema while keeping all existing schema fields unchanged.

+# Build networking, cache and CI
+
+### Build networking and cache
+
+The Dockerfile retains the pinned Python base, locked Python dependencies,
+`fonts-noto-cjk`, Debian repository signature checks, and offline artifact
+SHA256 verification. Production uses `scripts/build-verify.sh`; CI uses `scripts/ci-compose-verify.py`.
+Both build the same Dockerfile with BuildKit and retain `docker compose build --pull`.
+
+APT mirror hosts are configurable through `DEBIAN_MIRROR` and
+`DEBIAN_SECURITY_MIRROR` (hosts only, without scheme or path). Defaults are
+`deb.debian.org`; HTTPS is used for both Debian and security repositories.
+For mainland-China NAS builds, use the shared profile:
+
+```sh
+. ./deploy/build-cn.env
+./scripts/build-verify.sh
+```
+
+CI loads this same profile, using Tsinghua TUNA for both repositories unless
+Gitea repository variables `DEBIAN_MIRROR` / `DEBIAN_SECURITY_MIRROR` override
+it. Production may also set the two hosts directly in `.env` when calling the
+build script without the profile. An alternate mainland mirror is
+`mirrors.ustc.edu.cn`; availability and throughput depend on the Runner network.
+No fallback disables signature verification or removes packages.
+
+Layer order stays: pinned base → APT/font dependencies → `requirements.lock`
+→ pip dependencies → application/vendor source → build metadata.
+A source-only change therefore reuses the APT and pip layers, provided the
+same builder, base digest, mirror arguments, and optional offline artifacts
+are used. Changing the lockfile rebuilds pip and later layers, not APT.
+Changing the mirror or APT instructions rebuilds APT and later layers.
+
+Previously an APT layer miss redownloaded indexes/packages, and pip used
+`--no-cache-dir`. Now locked BuildKit mounts retain APT indexes, downloaded
+`.deb` files, and pip downloads/wheels outside the final image. Debian's
+`docker-clean` hook is disabled so it cannot discard cached packages.
+Re-executed APT steps still run `apt-get update` and validate repository
+signatures; cached packages and pip artifacts can avoid repeat large downloads.
+The initial build after this Dockerfile change will miss dependency layers;
+subsequent builds benefit. No measured speedup is claimed before CI completes.
+
+Caches belong to the Docker builder, not the ephemeral CI workspace. Keep the
+NAS Runner's builder storage across jobs; removing the builder, pruning caches,
+or using a fresh Docker daemon loses the benefit. Cache mounts are disposable:
+an empty cache still builds correctly. `--pull` remains enabled; a pinned base
+digest check alone does not invalidate dependency layers. To deliberately
+refresh installed APT versions, use `docker compose build --pull --no-cache`.
+
+### CI with a host Docker socket
+
+Run `python scripts/ci-compose-verify.py` after loading the build mirror profile.
+The script derives a temporary Compose document from production settings, with
+an absolute client-side build context, a UUID project name, a unique CI image
+tag, and project-scoped `data` / `config` named volumes. It removes production
+bind mounts, the fixed container name, host ports, and the production `.env`
+reference. A fresh test token, mock driver, and disabled device writes are
+explicitly configured. Docker initializes empty named volumes from the image's
+owned `/data` and `/config` directories; the service remains UID/GID 10333.
+
+Build contexts are sent by the Docker client, so the job workspace can remain
+inside the job container. Runtime storage is managed by the daemon; no matching
+NAS host `/workspace` directory is needed. HTTP readiness and the unmodified
+nine-endpoint smoke script run inside the service with `compose exec -T`.
+Restart is followed by another readiness check and the same smoke test.
+
+A `finally` block removes the test containers, network, volumes, and unique
+image tag on success or failure. The workflow records the private temporary
+Compose path in `GITHUB_ENV` and repeats cleanup in an `always()` step, covering
+normal cancellation/interruption. Failed cleanup retains the manifest so the
+fallback can retry. Abrupt host/daemon loss or a forcibly terminated entire job
+can prevent both cleanup paths; no CI script can guarantee cleanup in that case.
+No global prune or production resource removal is performed. Keep builder
+caches: only the run-specific image tag is removed.
+
+### CI Job pip indexes versus Docker build indexes
+
+The Job bootstrap runs `python scripts/ci-install.py` before Ruff/mypy/tests.
+It needs only the Python standard library, so it runs before PyYAML or tooling
+is installed. `CI_PIP_INDEX_URL` and `CI_PIP_FALLBACK_INDEX_URL` are optional
+Gitea repository variables. Defaults are the TUNA HTTPS PyPI simple endpoint
+and official `https://pypi.org/simple`. Each is attempted separately; the
+fallback repeats the unchanged editable `.[test]` installation, including
+PEP 517 build isolation and `setuptools>=75`. No simultaneous extra index is
+used, no build dependency is removed, and both failures fail CI.
+
+Logs show inherited index/config/proxy hosts and the selected index host for
+each attempt, with URL credentials and query strings removed. Bootstrap
+disables inherited pip config files via `PIP_CONFIG_FILE=/dev/null`, explicitly
+sets the selected index, and clears no-index/extra-index/find-links, insecure

+# KoKonna 错误、重试与阻塞处理
+
+核对日期：2026-10-16。依据：[KoKonna OpenAPI 官方文档](https://kokonna.art/pages/openapi)、[Requests 异常定义](https://requests.readthedocs.io/en/latest/_modules/requests/exceptions/)。本页区分厂商契约与 Frame Flow 的本地策略；没有文档保证的行为不作为自动重发依据。
+
+## 官方接口契约
+
+- 设备 API Key 使用 Bearer 鉴权；单设备每分钟上限 20 次，请求超限返回 429。
+- 上传成功返回新图片 ID 和计数，并立即激活新图；接口不提供幂等键或上传状态查询契约。
+- 删除可能改变当前图片。切换与删除都不能视为天然可重放。
+- 404 可表示方法不存在；图片下载时也可表示目标图片不存在。
+- 500 既可能是通用服务故障，也可能明确表示设备密钥无效、图片不存在或图片 ID 参数错误。实现只匹配官方明确列出的签名，其他 500 不猜测是否产生副作用。
+- 上传请求体上限 50 MB；本服务原图限制仍为 20 MiB，并保留像素上限和 base64 检查。
+- 官方文档未承诺服务处理时长、超时后的取消、事务回滚或 Retry-After 返回；不能靠等待固定时间证明写入没有执行。
+- Requests 将连接建立超时定义为可安全重试；读取超时不提供相同保证。一般连接异常也不能推定请求未发送。
+
+## 已落实的本地策略
+
+| 结果 | 处理 | 自动重试 | 设备阻塞 |
+| --- | --- | --- | --- |
+| 未配置密钥 | CONFIG_REQUIRED | 无 | 无 |
+| 明确的设备密钥无效 | CONFIG_REQUIRED，保存固定错误分类 | 无 | 无 |
+| 明确的图片不存在 | NOT_FOUND | 无 | 无 |
+| 明确的图片 ID 参数错误 | INVALID_REQUEST | 无 | 无 |
+| 明确的方法不存在 | UNSUPPORTED_CAPABILITY | 无 | 无 |
+| 其他 HTTP 4xx 拒绝 | 保存状态码，结束失败 | 除 429 外无 | 无 |
+| 本地请求预算耗尽 | 等待预算窗口 | 同一请求最多 3 次尝试 | 不创建 UNKNOWN |
+| HTTP 429 | RATE_LIMITED，尊重服务端冷却时间 | 最多 3 次尝试 | 耗尽后失败，不创建 UNKNOWN |
+| ConnectTimeout | 确定请求未发送 | 读写均最多 3 次尝试 | 耗尽后失败，不创建 UNKNOWN |
+| 只读查询的临时网络错误、通用 5xx、无效 JSON | CLOUD_UNAVAILABLE | 最多 3 次尝试 | 不创建 UNKNOWN |
+| TLS 异常 | 保存固定分类 | 无 | 写请求仍保守标为 UNKNOWN |
+| 写请求读取超时、一般连接异常、通用 5xx | 无法确定写入结果 | 不重发，只读核对 | UNKNOWN，保留保护 |
+| 写请求无效响应或无有效上传 ID | 无法确认成功 | 不重发，只读核对 | UNKNOWN，保留保护 |
+
+“最多 3 次”包含首次请求，重试发生在同一传输请求内，不重新渲染、不重新执行整个操作。普通退避为 1、2 秒；每次实际请求都计入本地 18 次/分钟预算。429 优先使用 Retry-After 秒数或 HTTP 日期；缺失/无效时按 60 秒。单次等待不超过 60 秒，超过此值保留冷却并结束当前尝试，不提前请求。没有无限循环，也不在重启后重放不确定的写入。
+
+操作错误的 details 保存 attempts、retryable、write_outcome，以及 transport_error / http_status / failure_kind 等固定分类。不会保存异常原文、完整下载 URL、带密钥的厂商消息或响应正文。是否重试由结果类别决定，不能仅依据 HTTP 500。
+
+## 未知写入的核对与升级
+
+上传前记录资产、哈希、字节数、名称、上传前图库和时间。响应丢失后只读查找并校验唯一候选；图片相同且设备已同步才能记为成功。已证明上传、但设备持续停留原图时，沿用两次稳定观察的失败关闭规则。
+
+没有候选、候选不唯一、内容不符、设备未同步、查询失败或缺少历史证据，都有独立恢复原因。图库没有目标图片不等于厂商保证从未接受请求，因此不自动把它改为失败或重传。
+
+`GET /api/v1/operations/{operation_id}` 的 `recovery` 返回：
+
+- `state`：checking / manual_review / resolved。
+- `reason`：gallery_match_missing、gallery_match_ambiguous、content_mismatch、waiting_device_sync、target_mismatch、read_unavailable、reconciliation_error、missing_upload_evidence 或 manual_reconciliation_required。
+- `first_checked_at`、`last_checked_at`、`checks`、`requires_manual_review`。
+
+只读核对每条操作至多每分钟一次。操作持续未知超过 sync_timeout + 300 秒（默认约 15 分钟）时，持久化一次 `operation.blocked` 事件和 `MANUAL_REVIEW_REQUIRED` 历史记录；服务重启、重复检查或原因改变均不会重复升级同一条未解决操作。既有检查继续运行，不自动取消设备保护。
+
+管理员可在 Webhooks 中订阅 `operation.blocked`；未配置订阅不会自动向外发送通知。事件和 API 记录始终保留，但它们不能替代已配置的通知渠道。单个任务失败、单条未知操作的元数据异常均不应中断其他任务处理。
+
+## 人工处理
+
+1. 根据 operation_id 查看原始错误、恢复原因、当前设备和图库；不点击重新执行来猜测结果。
+2. 调用现有 reconcile 接口并传 `acknowledge=false` 进行核对。
+3. 无法证明成功、但管理员确认可以结束旧操作时，传 `acknowledge=true`：结束为失败，保留原始目标、上传意图和此前错误，记录观察到的图片与人工处理历史。该接口不会重发设备写入。
+4. 有目标一致且同步完成的证据才记为成功。处理后恢复原计划，错过的任务不补发。
+
+仍可能因厂商无法给出明确写入结果而需要人工处理；本策略解决错误误判、可安全重试的暂时失败和长期阻塞缺乏解释的问题，不承诺网络故障时所有设备任务都能自动成功。

+The Mock-only `scripts/ui-layout-audit.cjs` checks all 11 navigation pages,
+local/cloud gallery layouts and six modal states plus expanded manual collage at 1440, 768 and 390 CSS pixels,
+in Chinese/English and light/dark themes. It checks page horizontal overflow and
+at least 8 pixels between visible input/select/textarea/button rectangles, and
+44-pixel control heights on mobile.
+Closed details, background content behind dialogs and hidden fields are excluded.
+Photos authentication is intercepted with fixture credentials; no NAS login or
+frame write occurs. Populated task/history fixtures remain in disposable Mock data.
+
+This audit found and corrected missing upload preview spacing, nested task field
+spacing, small mobile action gaps and inconsistent dynamically inserted form
+spacing. NAS source forms now hide irrelevant cloud credential fields. Native
+drive forms expose their credential field and hide local-only quality controls.
+
+Synology Photos has a dedicated connection card on the Photo Sources page, with
+status, an explanation of affected automation and a direct NAS sign-in dialog.
+Folder settings and person selection remain separate. Credentials are not saved;
+the existing protected session API is used. Successful login does not run a job
+or change frame content. Passwords are cleared from the dialog before submission.

+The workflow uses explicit `https://github.com/actions/...` URLs so Gitea's
+configured default Actions host cannot redirect downloads to the project owner's
+server. Forks download Actions through their own Runner/network; no public action
+mirror is served by this project. The former Tea auxiliary repository is private
+and is no longer required by current workflows.

-`UPSTREAM.json` records provenance. Upstream tag SHAs were checked using the official
-GitHub API; each cached subtree hash was compared to the upstream commit tree.
-No application secrets are stored in this public upstream-source cache; its own
-Actions are disabled. Intentional action updates must repeat tree verification
-and change the workflow pin. All validation steps remain unchanged.
+Keep the Runner's action cache and Python toolcache persistent. For Gitea Runner
+versions supporting `cache.offline_mode`, use a private Runner configuration:

-Python toolcache misses may still require setup-python to download Python from
-its upstream release source. This removes Action source download dependence,
-not every possible external download. No Runner or NAS network configuration is changed.
+```yaml
+runner:
+  file: /data/.runner
+cache:
+  offline_mode: true
+```
+
+In the Runner's own Compose service (not the application), set `HOME=/data` and
+`CONFIG_FILE=/data/config.yaml`, with `/data` already persisted. Before recreating
+an idle Runner, back up its configuration and copy the existing action cache from
+`/root/.cache/act` to `/data/.cache/act`. Preserve registration, labels, image,
+mounts and networks; do not interrupt active jobs or recreate other services.
+Verify cached actions against the pinned upstream commit and tree before reuse.
+This is administrator configuration, not a public workflow dependency.
+
+Offline reuse avoids refreshing cached actions from GitHub on each job. Moving
+tags/branches may remain at the cached version; this workflow deliberately pins
+immutable SHAs. A new action URL or commit requires an initial download or verified
+administrator prewarming; an old mirror subtree is not automatically equivalent
+to an upstream Git repository. Do not prune Runner caches between jobs. Python
+toolcache misses still download Python from its upstream release source. Network
+failures remain failures, never reasons to skip validation or silently fall back
+to the owner's Tea server.
+
+Administrators needing a mainland-specific download route can configure their
+own Runner/network cache privately. Such settings must not introduce public
+workflow references to a personal mirror. This change does not modify NAS VPN,
+proxy, firewall or other applications. All validation and deploy gates remain.

+
+### Production image retention
+
+Production uses `pigway-frame-flow:latest`. Builds first create a unique release
+image, then tag it as latest before activation. The old image is pinned during
+an update so a failed deployment can restore it. Only after the new version
+passes verification are old release/rollback images and duplicate tags removed.
+After successful deployment, only the current production image remains; there
