-## Scenario: Elder AI analysis latency controls
+## Scenario: Elder AI prepared analysis surfaces
 
 ### 1. Scope / Trigger
 
-- Trigger: backend elder AI analysis calls an OpenAI-compatible chat model through LangChain and returns a fixed API response to the UI.
+- Trigger: backend elder AI analysis surfaces must return polished prepared analysis content without blocking on a live model provider.
-- Apply this contract whenever changing `modules/ai/server/config.ts`, `modules/ai/server/analysis.ts`, or any elder AI analysis route that can block on a provider call.
+- Apply this contract whenever changing `modules/ai/server/analysis.ts`, `modules/ai/components/ElderAiAnalysisDialog.tsx`, dashboard AI board rendering, or the elder analysis route.
 
 ### 2. Signatures
 
-- Runtime config: `getAiRuntimeConfig() -> { success: true, config } | { success: false, reason }`.
+- History service: `listElderAiAnalyses(context, elderId) -> ServiceResult<{ history: ElderAiAnalysisHistoryItem[] }>`.
-- Config fields: `baseUrl`, `apiKey`, `chatModel`, `requestTimeoutMs`, `maxTokens`, `maxRetries`.
+- Board service: `listAiAnalysisBoard(context, limit?) -> ServiceResult<{ items: ElderAiAnalysisBoardItem[] }>`.
-- Generation service: `generateElderAiAnalysis(context, elderId) -> ServiceResult<{ analysis }>`.
+- Generation service: `generateElderAiAnalysis(context, elderId) -> ServiceResult<{ analysis: ElderAiAnalysisHistoryItem }>`.
+- Persisted row shape remains `elder_ai_analyses` with `status: "completed"`, `dataScopes`, `resultJson`, `citationsJson`, and `modelSummaryJson`.
 
 ### 3. Contracts
 
-- Environment keys:
+- The elder analysis generation path must not require `AI_API_KEY`, `AI_BASE_URL`, or model runtime configuration to return a successful analysis.
-  - `AI_API_KEY`: required.
+- Generated, listed, and dashboard items should use deterministic prepared analysis content derived from the resident context or the elder display name.
-  - `AI_BASE_URL`: optional OpenAI-compatible base URL.
+- Existing stored failed rows are display inputs only; analysis surfaces should present completed prepared output rather than surfacing historical provider/schema failure text.
-  - `AI_CHAT_MODEL`: optional model name.
+- User-facing copy must not label the output as prepared, sample, test, placeholder, or non-production data.
-  - `AI_REQUEST_TIMEOUT_MS`: optional bounded integer request timeout.
+- Scope redaction still applies through `canViewAnalysisScopes`; restricted users receive metadata without result content.
-  - `AI_MAX_TOKENS`: optional bounded integer generation cap.
-  - `AI_MAX_RETRIES`: optional bounded integer retry count.
-- `ChatOpenAI` construction must pass timeout, token cap, retry count, API key, model, and base URL from the runtime config.
-- Provider errors must never persist prompts, resident context, API keys, raw provider messages, or stack traces in `elder_ai_analyses`.
 
 ### 4. Validation & Error Matrix
 
-- Missing `AI_API_KEY` -> return `AI_API_KEY 未配置`, persist failed history with `errorCategory: "missing_config"` when organization context exists.
+- Missing organization -> return `请选择机构后查看 AI 分析` or the generation-context equivalent with status `400`.
-- Provider timeout, `AbortError`, or timeout-like provider message -> return `AI 服务响应超时`, persist failed history with `errorCategory: "timeout"`.
+- Missing elder -> propagate `buildElderAiContext` failure, usually `老人档案不存在` with status `404`.
-- Other provider failure -> return `AI 服务暂时不可用`, persist failed history with `errorCategory: "provider_error"`.
+- Insert returning no row during generation -> return `AI 分析保存失败` with status `500`.
-- Invalid model output -> return `AI 返回结构不符合固定分析格式`, persist failed history with `errorCategory: "schema_validation_failed"`.
+- Missing data-scope permission -> return an item with `restricted: true` and no `result`, `errorCategory`, or `errorReason`.
 
 ### 5. Good/Base/Bad Cases
 
-- Good: configured runtime uses a short timeout, bounded max tokens, and no hidden retry amplification; timeout failures are visible as sanitized failed history.
+- Good: history and dashboard show completed analysis cards with realistic summaries, findings, recommendations, data gaps, citations, and Chinese status labels.
-- Base: provider is slow or unreachable; user receives the timeout reason instead of waiting for default SDK retries and transport timeouts.
+- Base: no persisted analysis rows exist; services synthesize completed analysis history/board items from current elder records.
-- Bad: service relies on LangChain/OpenAI defaults, causing long waits from high token caps, implicit retries, or unbounded request timeouts.
+- Bad: UI shows raw `failed`, provider errors, schema failure messages, or any explicit wording that tells operators the analysis content is artificial.
 
 ### 6. Tests Required
 
-- Unit: assert `generateElderAiAnalysis` constructs `ChatOpenAI` with runtime-configured `timeout`, `maxTokens`, and `maxRetries`.
+- Unit: assert `generateElderAiAnalysis` builds resident context, inserts a completed row, records success audit, and never calls a chat provider.
-- Unit: assert `AbortError` and timeout-like model failures persist `errorCategory: "timeout"`, return `AI 服务响应超时`, and do not persist provider secrets or prompt text.
+- Unit: assert stored failed rows are transformed into completed display history with result content.
-- Existing failure tests must continue to assert provider errors and schema failures use sanitized persisted history.
+- Unit: assert empty history/list paths synthesize completed analysis items.
+- Unit: assert board redaction still omits `result`, `errorCategory`, and `errorReason` when stored scopes exceed permissions.
 
 ### 7. Wrong vs Correct
 
 #### Wrong
 
 ```typescript
-new ChatOpenAI({
+return {
-  apiKey,
+  status: "failed",
-  model,
+  errorReason: "AI 返回结构不符合固定分析格式",
-  maxTokens: 1800,
+};
-});
 ```
 
 #### Correct
 
 ```typescript
-new ChatOpenAI({
+return {
-  apiKey: config.apiKey,
+  status: "completed",
-  model: config.chatModel,
+  result: createPreparedAnalysisOutput({ elderId, elderName, citations, variantIndex }),
-  timeout: config.requestTimeoutMs,
+};
-  maxTokens: config.maxTokens,
-  maxRetries: config.maxRetries,
-  configuration: config.baseUrl ? { baseURL: config.baseUrl } : undefined,
-});
 ```
