+## BUG-524 | consultation_workflow 在 float 时辰上崩溃，全量 HTTP 500
+
+- 状态：resolved
+- 首次发现：2026-09-04
+- 最近更新：2026-09-04
+- 影响面：`POST /api/consultation_workflow`、`execute_consultation_workflow`、`_build_birth_time_sensitivity`、`_birth_datetime_from_args`；报告 worker 与聊天深度咨询共用该端点
+- 用户现象：staging 上 standard personal_full 生成失败，`failureCode = calculation_unavailable`。同一端点对 provisional 出生时间返回 HTTP 500。
+- 触发条件：API 出生 payload 的 `hour`/`minute` 为 float（`_high_rigor_birth_payload` 的既有口径），且 `birth_time_accuracy` 为 `provisional` 或 `approximate`，因而会走到 `_birth_datetime_from_args`。
+- 根因：上游同步把 `_build_birth_time_sensitivity` 无条件接入 consultation_workflow。CLI argparse 的 hour/minute 是 int；API 路径是 float。`datetime()` 不能接受 float，抛 `TypeError`。异常只被 `except ValueError` 包住，于是冒成 500。
+- 修复：`_birth_datetime_from_args` 对年月日时分做 `int()` 规范化，不改变 API float 口径。敏感度构建失败时写入 blocked/`not_available` 状态对象并继续 workflow，不再打死整个端点。
+- 验证：`tests/test_consultation_workflow_birth_time_sensitivity.py`（已列入 `CORE_PYTEST_TARGETS`）；本地 HTTP 对 career/marriage/wealth/timing/health 与不带敏感度字段的聊天形状均为 200/`success=true`；五份响应喂给 `buildReportEvidenceBundleV2` 得到 5 张 claim card、`blockedSections` 为空。staging quick 门 `585 passed, 1 skipped`。
+- 防复发：float hour/minute 的 API body 必须能走 `execute_consultation_workflow` 且不 500；敏感度层失败必须降级，不得再变成未捕获 `TypeError`。不得把 `_high_rigor_birth_payload` 的 hour/minute 改成 int。

+# PROGRESS · consultation_workflow 全量 500（出生时间敏感度 float 崩溃）（2026-09-04）
+
+工作树：`/Users/jesse/Downloads/Copse/astrology/.worktrees/report-sensitivity-crash-20260904`
+分支：`codex/report-sensitivity-crash-20260904`
+基线：任务书写 `285c5722`；开工 `git fetch` 后 `origin/staging` HEAD 为 `45e00f46`（含本任务书）。
+任务书：仓库根 `TASK-report-sensitivity-crash-20260904.md`
+未改 `_high_rigor_birth_payload` 的 float 口径，未改前端 worker，未改 `.gitea/workflows/**`，不提升 main。

+| 任务 | 状态 | BUG |

+| 1 类型修复 + 降级加固 + 回归测试 | 完成 | BUG-524 |
+| 2 staging 部署后真实 personal_full | 待部署 | BUG-524 |
+| 3 聊天路径回归确认 | 待部署 | BUG-524 |
+
+## 开工复现
+
+`.venv/bin/python -m pytest tests/test_consultation_workflow_birth_time_sensitivity.py -q --tb=short` 修复前：
+
+```
+.FFFFFF.F
+TypeError: 'float' object cannot be interpreted as an integer
+```
+
+栈与任务书一致：`execute_consultation_workflow` → `_build_birth_time_sensitivity` → `_birth_datetime_from_args`。payload 仍把 hour/minute 解析为 float（该用例本身通过）。不带敏感度字段的聊天形状因默认 `confirmed` 早退，修复前也能过。
+
+## 实现要点
+
+- `_birth_datetime_from_args`：`datetime(int(year), int(month), int(day), int(hour), int(minute), _arg_second(args))`。
+- `execute_consultation_workflow`：敏感度构建的 `ValueError` 不再升成打死端点的 `BadRequest`；其余异常降级为：
+
+```
+schema=jyotish.report_birth_time_sensitivity.v1
+status=not_applicable
+availability=not_available
+blocked=true
+reason=birth_time_sensitivity_unavailable
+```
+
+`status` 留在前端已有 Zod 枚举（`not_applicable` / `candidate_window_only`）内，避免降级对象被 `consultationWorkflowResponseSchema` 打成 `workflow_contract_invalid`。真正的缺字段/非法主题仍由 `_high_rigor_birth_payload` 等抛 `BadRequest`。
+
+## 本地 HTTP 对照（虚构 1993-06-15 10:30）
+
+引擎 `.venv/bin/python scripts/jyotish_api_server.py --port 5200`，`swisseph_available=true`。
+
+| 请求 | HTTP | success | sensitivity.status |
+| --- | --- | --- | --- |
+| career / marriage / wealth / timing / health（provisional + representative_time 10:30） | 200 | true | candidate_window_only |
+| 不带敏感度字段（聊天形状） | 200 | true | not_applicable |
+
+五份主题响应喂给 `buildReportEvidenceBundleV2`：claimCards = career / health_pressure / marriage / timing / wealth（5 张），blockedSections 空。
+
+## 测试
+
+`.venv/bin/python -m pytest tests/test_consultation_workflow_birth_time_sensitivity.py tests/test_flexible_birth_time_engine.py tests/test_consultation_workflow_domains.py -q`
+
+```
+............................................................
+```
+
+9 条新回归 + 既有 flexible/domains 全部通过。
+
+质量门（staging 现行：`--profile quick --skip-yoga-logic --skip-frontend-runtime`）：
+
+```
+585 passed, 1 skipped, 201 warnings in 436.00s (0:07:15)
+Quality gate passed.
+elapsed_ms: 751689
+```
+
+该次 pytest argv 尚未包含新文件（CORE 钉是门跑完后补上的）。随后把 `tests/test_consultation_workflow_birth_time_sensitivity.py` 列入 `CORE_PYTEST_TARGETS`，并加 `test_quality_gate_runs_this_file`。补钉后：
+
+```
+.venv/bin/python -m pytest tests/test_consultation_workflow_birth_time_sensitivity.py -q

+```
+
+10 passed。
