+## Scenario: Live OCR Sample Stdin Probe
+
+### 1. Scope / Trigger
+
+- Trigger: an authorized real PDF must prove Tencent credentials, network,
+  subtype normalization and required-field behavior without creating an OA
+  invoice or persisting the sample on the execution host.
+- This probe is intentionally one-file and PDF-only. It does not retain the
+  historical manifest, directory scan, image evaluation or legacy VAT-only
+  command modes.
+
+### 2. Signatures
+
+- Command:
+  `node scripts/qa/check-ocr-provider-samples.mjs --alias=SAMPLE-PDF-<SAFE_ALIAS>`.
+- Input: exactly one PDF on stdin, at most `OCR_PDF_MAX_BYTES` (7 MiB).
+- Runtime env: `TENCENT_SECRET_ID`, `TENCENT_SECRET_KEY`, optional
+  `TENCENT_OCR_REGION` and `OCR_TIMEOUT_MS`; provider is fixed to `tencent`.
+- Provider boundary: `runOcrForInvoice({ config, ocrType: "vat",
+  imageBase64, sourceMimeType: "application/pdf" })`.
+- Output: one JSON object containing only `alias`, `provider`, `status`,
+  `transportMode`, `elapsedMs`, safe document category/subtype/count,
+  per-field hit booleans, missing field names and a bounded error code.
+
+### 3. Contracts
+
+- The caller selects one authorized PDF explicitly and streams it through
+  stdin. The probe never accepts a file path, directory, manifest, image or
+  batch list and never writes sample bytes to disk, OA storage or the database.
+- Alias must match `SAMPLE-PDF-[A-Z0-9_-]+`; it replaces the original file name
+  in every output and evidence record.
+- Validate the 7 MiB limit, PDF version header and terminal `%%EOF` before
+  constructing Base64 or invoking Tencent. One process performs at most one
+  provider call.
+- Reuse `RecognizeGeneralInvoice`, `sanitizeOcrResultForPersistence` and the
+  production category-specific required-field rules. The probe must not carry
+  a parallel VAT-only field list.
+- Never output recognized identifiers, dates, amounts, buyer/seller/passenger
+  names, provider messages, raw response or input bytes. Field presence is a
+  boolean; errors are bounded stable codes.
+- A PASS proves the direct provider/normalization path only. It does not prove
+  OA upload, queue, persistence, duplicate detection, binding or reimbursement
+  submission.
+
+### 4. Validation & Error Matrix
+
+- Missing/invalid alias -> `sample_alias_invalid`; no provider call.
+- Empty stdin -> `sample_empty`; no provider call.
+- More than 7 MiB -> `sample_too_large`; stop reading and do not call provider.
+- Invalid header or missing terminal EOF -> `sample_pdf_invalid`; no provider
+  call.
+- Missing credentials or provider mismatch -> `ocr_credentials_missing` /
+  `ocr_provider_invalid`; no business values in output.
+- Supported subtype with missing category-required fields -> `status=HOLD`
+  plus field names only.
+- Tencent failure -> `status=HOLD` plus a bounded SDK error code; omit the
+  provider message and raw error object.
+
+### 5. Good/Base/Bad Cases
+
+- Good: stream one railway electronic ticket using an anonymous alias; receive
+  `electronic_train_ticket`, boolean field hits and no recognized values or
+  persisted sample.
+- Base: stream one supported accommodation invoice and receive a PASS summary
+  for its VAT/full-VAT category.
+- Bad: point the probe at a directory, auto-run every PDF, write a manifest with
+  real paths, accept images, print OCR values or retain the sample remotely.
+
+### 6. Tests Required
+
+- Unit tests inject synthetic provider results for VAT, full VAT and railway
+  categories and assert category-aware required fields.
+- Negative tests assert non-PDF, truncated PDF and oversized input fail before
+  the provider mock is called.
+- Privacy tests seed raw provider and recognizable normalized markers, then
+  assert serialized output contains only booleans and safe metadata.
+- CLI test pipes one synthetic PDF over stdin with credentials absent and
+  asserts one parseable redacted error object with empty stderr.
+- Before deployment run `node --check`, the focused tests, full backend tests,
+  sensitive-content scan, task validation and Trellis governance.
+
+### 7. Wrong vs Correct
+
+#### Wrong
+
+```bash
+PLAYWRIGHT_OCR_LIVE_DIR=<sample-dir> \
+  node scripts/qa/check-ocr-provider-samples.mjs --provider=tencent --json
+```
+
+#### Correct

 8. 正常清理或归档测试业务记录，再允许杨俊提交真实票据。
 
+### 授权样票验证工具边界
+
+- 既有 `check-ocr-provider-samples.mjs` 必须与生产 adapter 使用同一 `RecognizeGeneralInvoice` 入口和按票种必填字段规则，不得继续引用已删除的 VAT-only 导出或把铁路电子客票套入 VAT 五字段门禁。
+- 真实 PDF 从本地受控、Git 忽略的样票目录按匿名别名选择，经 SSH 标准输入直接流入生产 server 容器内存；不得把原件、临时副本或 manifest 写入远端磁盘、OA 附件存储、数据库、仓库或报告。
+- 每个进程只接收一份 PDF，验证文件签名和 7MiB 上限后最多调用一次 `RecognizeGeneralInvoice`。住宿与铁路样票分两次执行，任一失败立即停止，不自动遍历目录中的其他文件。
+- 输出只允许匿名别名、provider、票种、安全传输模式、耗时、字段命中布尔值、缺字段名和稳定错误码；不得输出文件名、原始响应、识别值、人员/企业名称、票号、金额或票面内容。
+- live runner 的代码、合成测试和生产部署先通过，再单独取得两次真实 API 调用批准；工具可用不等于真实样票已验证。

 ## 文档口径
 
 - `docs/员工快速上手.md` 增加一页式差旅报销步骤：火车票和住宿费拆明细，官方 PDF 绑定对应明细，两类费用均附支付截图，金额差异必须说明，提交后进入主管和财务流程。
