+# Issue priority automation
+
+`Issue Triage Labels` keeps three independent sources of priority:
+
+- `user-priority/P0`–`P3`: the reporter's requested urgency, handled by the existing label script.
+- `ai-priority/P0`–`P3`: an AI suggestion for repair/implementation order based on the reported impact, scope, regressions and workarounds.
+- Maintainer labels such as `P0` or `P3`: human decisions; the AI never modifies them and they take precedence.
+
+AI suggestions are not verified diagnoses, proof that an issue is valid, or release commitments. The model sees only bounded issue title/body text and database/type labels, not source code, comments, linked pages or screenshot contents. It cannot establish actual production-wide impact. Priority fields and user-priority labels are excluded from its input to avoid copying the reporter's selection.
+
+## Rubric
+
+| AI label | Repair / implementation priority |
+| --- | --- |
+| `ai-priority/P0` | Critical security exposure, irreversible persistent data loss/corruption caused by normal DBX operations, or widespread core failure without a viable workaround; concrete evidence and high confidence required. Destructive defects are not downgraded solely because few users or one engine are currently affected, or because backups exist. Immediate maintainer review. |
+| `ai-priority/P1` | Major non-destructive core workflow blocked, significant regression, serious recoverable risk, or a missing capability demonstrably blocking a common core workflow; P0 conditions take precedence. |
+| `ai-priority/P2` | Meaningful functional bug or useful feature with limited impact or a practical workaround. |
+| `ai-priority/P3` | Cosmetic issues, minor convenience, optional polish or narrowly useful low-impact enhancements. |
+| `ai-priority/needs-info` | Insufficient evidence, low confidence or an unsupported critical-priority assessment; not a default P2. |
+
+Bug severity alone is not feature priority: a broadly blocking missing capability may outrank a minor bug. Requested deadlines and urgency do not determine either. The response must cite exact title/body evidence; invalid or invented evidence is rejected. The rationale, confidence, evidence, missing information and model are recorded in the Actions step summary, without posting issue comments.
+
+## Configuration
+
+1. Set the repository Actions secret `ATLASCLOUD_API_KEY`. Never commit credentials.
+2. Optionally set the repository variable `ISSUE_TRIAGE_MODEL`. The default is `deepseek-ai/deepseek-v3.2`.
+3. Deploy the workflow and script on the default branch. Existing `workflow_dispatch` and database-label synchronization behavior is unchanged; no historical-issue backfill is performed.
+
+The integration uses AtlasCloud's `https://api.atlascloud.ai/v1/chat/completions` endpoint, Bearer authentication, non-streaming Chat Completions and JSON mode. The default model ID and JSON-mode capability were checked against `/v1/models` on 2026-09-17. A replacement model must support the same request/response format. See `https://www.atlascloud.ai/docs/zh/models/llm` for the provider's integration documentation.
+
+New and reopened open issues are evaluated, as are title/body edits. This includes changes solely to the user-priority field: that field is still excluded from the model input, but skipping the replacement run could lose an assessment if the preceding workflow was canceled by concurrency. Input is capped to a 500-character title and 14,000 body characters (start and end retained), with up to 1,500 output tokens and a 60-second request timeout. There are no automatic retries. Each eligible event can incur a paid provider call, and bounded public issue text is sent to AtlasCloud.
+
+Maintainers can create and apply `ai-priority/skip` to opt an issue out; existing AI labels are then left untouched. Editing comments alone does not trigger this workflow, so important clarification should also be added to the issue body.
+
+Missing credentials skip AI with a warning. Provider/authentication/timeout/invalid-output failures occur before any label writes and preserve previous classifications. The AI step is non-blocking and does not prevent the existing database/title/user-priority flow from succeeding. Before writing, the script rechecks that the issue remains open, is not opted out and its assessment input has not changed. A new AI label is added before obsolete AI priority labels are removed; a GitHub write failure may require a later eligible event to reconcile them. No other label namespaces, assignees, issue states or comments are modified.
+
+## Validation
+
+```sh
+node --test .github/scripts/ai-issue-priority.test.mjs .github/scripts/label-issue-database.test.mjs
+node --test .github/scripts/*.test.mjs
+```
+
+For a read-only end-to-end check, supply the usual Actions event/token variables and set `DRY_RUN=1`. This still calls AtlasCloud and reads the issue from GitHub, but makes no GitHub writes. Never print the environment or include a real key in fixtures, command arguments or logs.

+Apply these priorities in order, checking the P0 conditions before P1:
+- P0: a specific report of critical security exposure or irreversible persistent data loss/corruption caused
+  by a normal DBX operation, or widespread failure of the entire application's core functionality without
+  a viable workaround. Requires high classification confidence and a critical risk category.
+  Normal save/update/delete operations unexpectedly damaging unrelated stored records are P0, even if only
+  one database engine or a few users are currently known to be affected. Restoring backups or avoiding the
+  unsafe operation does not lower that destructive defect to P1. Concrete steps/observations are required;
+  a bare claim of data loss or a scary keyword is not enough. Not for ordinary feature requests, urgency,
+  cosmetic defects or an isolated connection failure.
+- P1: major NON-DESTRUCTIVE core workflow blocked, significant regression or serious recoverable risk with no practical
+  workaround; also an important missing capability that demonstrably blocks a common core workflow.
+- P2: meaningful functional defect or useful feature with limited impact or a practical workaround;
+  ordinary feature requests belong here only when their problem and benefit are concrete.
+- P3: cosmetic/text issues, minor convenience, optional polish or narrowly useful low-impact enhancements.

+Reported facts are not verified facts. Attribute claims to the report rather than claiming verification.

+# CI job boundaries
+
+Paths in this guide are relative to `.github/`.
+
+`workflows/ci.yml` retains one workflow and one cancellation group. Splitting jobs
+does not change release workflows or branch-protection settings. The existing
+`rust` and `agents` aggregate check names remain; `ci` additionally summarizes all
+selected jobs. None of these gates accepts a failed, cancelled, missing, or
+unexpectedly skipped prerequisite.
+
+## Selection
+
+`scripts/ci-plan.mjs` reads Cargo workspace metadata and the exact event base/head
+diff. Renames include both paths and deleted paths remain visible. Rust package
+selection follows reverse dependencies, including build and test dependencies.
+Connection-type descriptors belong to `dbx-types`; dialect descriptors belong to
+`dbx-sql`. A changed core dependency also selects the standalone DuckDB Agent tests,
+whose development dependency is `dbx-core`.
+
+- Ordinary Rust PRs select foundation, driver, and application test groups from
+  `scripts/ci-config.mjs`. Each group contains several packages, not one runner per
+  crate. At most three Rust test groups run concurrently.
+- Main pushes, shared Cargo manifests/locks, toolchain/config/vendor changes, CI
+  infrastructure changes, an unknown workspace member, or an unavailable diff
+  select the original full-workspace test lane instead of duplicating it with all
+  three groups.
+- Strict clippy still checks the complete workspace and all targets. The existing
+  full/fast feature distinction is retained: fast skips system-font discovery,
+  not the other previously enabled capabilities.
+- Native Agent source changes select the affected native driver and its live
+  cases. Shared Agent inputs conservatively select all existing Agent checks.
+  Windows DuckDB packaging is selected by its own inputs or shared build/lock
+  changes, not every change to its development dependency's source.
+- Existing frontend, package, Windows, JDBC, offline-payload and Nix jobs retain
+  their commands and path filters.
+
+Changes to the planner itself select the broad checks. Missing/invalid planning
+data fails the aggregate gates rather than producing a successful skip.
+
+## Fast checks and Rust feature coverage
+
+`fast-checks` runs formatting and CI/architecture contracts before dependency
+resolution or compilation. It checks generated connection types without rewriting
+them and validates the relevant root and independent Agent Cargo lockfiles with
+full `cargo metadata --locked`; `--no-deps` is intentionally not used for that
+validation.
+
+Cargo may unify features supplied by different workspace consumers. Grouped tests
+therefore explicitly retain the features previously enabled on each package,
+including plugin runtime defaults and the driver's bundled SQLite capability.
+`scripts/ci-rust-coverage.mjs` compares each selected workspace package's enabled
+features with the full-workspace invocation and verifies that the groups cover
+every workspace member exactly once. It fails if a selected package loses a
+feature. An unassigned new workspace member forces the full-workspace lane and
+bypasses only the group-specific audit until it is assigned a group. This does not substitute for
+the full-workspace integration lane, and does not use `--all-features` to combine
+incompatible SQLite backends.
+
+## Agent jobs
+
+| Job | Coverage | Maximum parallelism |
+| --- | --- | --- |
+| `agent-checks` | Existing Python/script tests and Agent source validation | 1 |
+| `agent-java` | Existing Java tests, `shadowJar`, and JAR validation | 1 |
+| `agent-rust` | DuckDB and TDengine tests; TDengine release build | 2 |
+| `agent-go` | Ten existing native Go test/build targets, original race flags, six ZooKeeper cross-build targets | 4 |
+| `agent-integration` | Sixteen existing engine/version/authentication cases | 4 |
+
+Matrix jobs set `fail-fast: false`, so one failure does not conceal results from
+the other selected cases. Live test predicates, readiness checks, time limits,
+credentials for disposable fixtures, and failure cleanup are retained.
+Native, Java and live jobs wait for fast checks and Agent source validation before
+starting expensive builds or containers.
+RocketMQ's existing integration harness starts official server JARs through Maven
+and Java rather than Docker; those matrix entries explicitly retain Java 21.
+
+| Integration scenario | Versions |
+| --- | --- |
+| ZooKeeper | 3.4.14, 3.5.5, 3.7.0, 3.9.5; large-child-list coverage remains on 3.7.0 |
+| ZooKeeper SASL DIGEST-MD5 | 3.7.0 |
+| RocketMQ | 4.9.8, 5.3.1 |
+| TDengine | 2.4.0.14, 2.6.0.34, 3.0.7.1, 3.3.6.13, 3.4.2.2; the last uses `tdengine/tsdb` |
+| Cassandra | 3.11.19, 5.0.6 |
+| RabbitMQ | 3.13, 4.3 |
+
+## Validation
+
+Run these from the repository root:
+
+```sh
+node --test .github/scripts/ci-*.test.mjs
+node .github/scripts/ci-rust-coverage.mjs
+actionlint .github/workflows/ci.yml
+bash -n .github/scripts/ci-agent-go.sh
+bash -n .github/scripts/ci-agent-integration.sh
+```
+
+The shell-command tests replace Docker, compilers, readiness probes and delegated
+integration scripts with recording stubs. They verify all configured cases and
+failure propagation without starting an engine; they are not live database tests.
+Do not run the integration shell script on a developer machine. It targets
+disposable Actions runners; equivalent validation on the designated test server
+must follow that server's isolated-container naming and port policies.
+
+The split aims to isolate failures, return small-check results earlier, and remove
+unrelated work. Rust groups can still repeat dependency compilation across runners;
+compare cold/warm build, link, test and queue time on actual runs before claiming a
+speedup or changing group sizes. Cancelled runs are not successful benchmarks.

 ```

+### macOS Development Signing
+
+Use `make dev`, `make dev-fast`, or `pnpm dev:tauri`. These entry points sign each rebuilt debug executable with a stable, local-only development identity before launching it. The first launch may still ask you to select **Always Allow** for DBX's existing Keychain item; subsequent rebuilds keep the same code identity. Direct `pnpm tauri dev` bypasses this setup.
+
+The first run creates a dedicated signing keychain and a self-signed certificate under `~/Library/Application Support/DBX/development-signing/`. It adds only this keychain to your user search list, without changing the default keychain or system trust settings. The directory is owner-only (`0700`); its files, including the generated password used to unlock this development-only signing keychain, are owner-only (`0600`). No release private key or DBX connection-encryption key is exported or replaced. Keep this local identity across rebuilds; do not commit or share it. An incomplete, corrupt, or expired identity fails explicitly rather than silently rotating or falling back to ad-hoc signing.
+
+The runner is restricted to `debug/dbx`, preserves Cargo feature and application arguments, and does not run for Linux, Windows, or release packaging. Custom `CARGO_TARGET_*_RUNNER` variables must be unset for these macOS development entry points.
+
+Core, desktop and Web storage test fixtures use `dbx_core::persistence::test_storage` (the `test-support` dev-dependency feature). They resolve their own data-directory keys before migration preflight, without accessing the user's Keychain or inheriting `DBX_SECRET_KEY` / `DBX_SECRET_KEY_FILE`. Keep the fixture directory and its key together when testing database copies.
+
+```bash
+node --test scripts/dev-tauri.test.mjs
+DBX_TEST_MACOS_KEYCHAIN=1 node --test scripts/dev-tauri.test.mjs
+```
+
+The opt-in macOS integration test creates and removes a temporary signing keychain. It verifies that an ad-hoc rebuild is denied and that two different builds signed with the same identity can read the same test item with system interaction disabled.

+### macOS 开发签名
+
+请使用 `make dev`、`make dev-fast` 或 `pnpm dev:tauri`。这些入口会在每次重新编译后、启动前，用固定的本地开发身份签名。首次启动仍可能需要对 DBX 原有钥匙串条目选择一次“始终允许”，之后重编译保持相同代码身份。直接执行 `pnpm tauri dev` 会绕过此流程。
+
+首次运行会在 `~/Library/Application Support/DBX/development-signing/` 创建独立签名钥匙串和自签开发证书，仅将该钥匙串加入当前用户的搜索列表，不更改默认钥匙串或系统信任设置。目录权限为 `0700`，文件权限为 `0600`；其中保存的随机密码只用于解锁这个开发签名钥匙串。不使用发布私钥，也不导出或更换已有连接的加密密钥。请保留这套本地身份，不要提交或分享；配置不完整、损坏或证书过期时会明确报错，不会自动换证书或降级为临时签名。
+
+签名 runner 仅接受 `debug/dbx`，保留 Cargo feature 和应用参数，不影响 Linux、Windows 或正式打包。使用这些 macOS 开发入口时，需要取消自定义的 `CARGO_TARGET_*_RUNNER` 环境变量。
+
+Core、桌面端和 Web 的 Storage 测试夹具使用 `dbx_core::persistence::test_storage`（仅由开发依赖启用 `test-support` feature），在迁移预检查前选择测试目录自己的密钥，不访问用户钥匙串，也不继承 `DBX_SECRET_KEY` / `DBX_SECRET_KEY_FILE`。测试数据库复制时，应将夹具目录及其密钥一起保留。
+
+```bash
+node --test scripts/dev-tauri.test.mjs
+DBX_TEST_MACOS_KEYCHAIN=1 node --test scripts/dev-tauri.test.mjs
+```
+
+第二条为 macOS 集成验证：创建并清理临时签名钥匙串，禁止系统交互，证明临时签名重编译会被拒绝，而采用同一稳定身份的两个不同构建仍能读取同一测试条目。

 Open `http://localhost:4224` in your browser. Multi-arch images (amd64 / arm64) are available.

+Connection, plugin, AI, and tunnel credentials are encrypted before they are
+written to `dbx.db`. Desktop builds use the local platform credential store
+(macOS Keychain, Windows Credential Manager, or Linux Secret Service).
+Web/Docker and directly running `dbx-web` use the same managed data-directory
+key by default: `${DBX_DATA_DIR}/.dbx/secret.key`. The key is created only when
+migration starts or the first sensitive value is written, and must be backed up
+together with `dbx.db`. Persisting `/app/data` is therefore sufficient for a
+normal Docker deployment. This key protects the database contents, but cannot
+protect the whole data volume if the volume itself is copied or exposed.
+
+For production deployments, replace the managed key with a Docker/Kubernetes
+Secret by setting `DBX_SECRET_KEY_FILE`, or provide `DBX_SECRET_KEY` through a
+secret manager. Explicit keys take precedence and must never be rotated while
+encrypted data is in use. Without a usable key, business APIs remain blocked
+and the browser displays the data security upgrade screen.
+
+When running the binary directly, set `DBX_DATA_DIR=/var/lib/dbx` to use
+`/var/lib/dbx/.dbx/secret.key` with the same lifecycle and backup rules.
+
+When upgrading from a release that stored credentials in plain text, Desktop
+and Web display a **Data Security Upgrade** wizard before opening the main
+application. Choose **Start upgrade** to create a restricted backup, migrate
+legacy database/JSON credentials, and verify that encrypted values can be
+read. Failures retain the original data and backup; fix the issue shown in
+the wizard and choose **Retry**. The backup path is shown after success.
+Once you have verified your connections, **Delete migration backups** asks
+for confirmation and removes the migration backup directory and the legacy
+JSON `.bak` files created by that migration. Unrelated backup files are kept.
+Users with no legacy data proceed directly after the initial check.
+
+Local CLI and standalone MCP can reuse the existing platform credential
+store on the same device, or read an explicitly configured
+`DBX_SECRET_KEY_FILE`/`DBX_SECRET_KEY`. They do not create keys during the
+startup check or automatically migrate legacy data. A
+`DATA_MIGRATION_REQUIRED` error means that you must first open the same data
+directory in Desktop or Web and complete its upgrade wizard. For headless
+hosts without a platform credential store, configure the persistent key.
+
+Cross-device exports use a separate sync passphrase and never contain the
+local storage key. A direct `dbx.db` copy is not a cross-platform sync method:
+platform keys do not move with the database. Use encrypted export/import so
+the target device stores credentials using its own local key.
+
+For the complete design, migration state machine, implementation map,
+troubleshooting, and test plan, see
+[DBX Data Security Upgrade and Migration](docs/data-security-migration.md).
