ob_ai_call is the only input to V2 pricing, and it was dropping the two numbers needed to interpret its own cost column. tokens_reasoning was captured from the provider response but never written to the table, so the cost of thinking mode was invisible once it left the process. Folding it into tokens_out was not an option either -- it is billed at the output rate, and mixing the two hides exactly the difference we now have to watch. rate_tier records which price list applied. Without it a row's cost_cents cannot be rechecked: DeepSeek's peak rate is double off-peak from 2026-08-17, so recomputing an old row at "the current rate" silently produces a different answer than what was actually billed. Migration 0002 adds both columns. tokens_reasoning defaults to 0 rather than NULL so cost aggregates do not collapse to NULL on historical rows; rate_tier stays nullable because rows written before this change genuinely have an unknown tier, and NULL says that more honestly than a guessed 'flat'. The smoke script now asserts both: reasoning tokens must be 0 (a non-zero value means a provider default re-enabled thinking mode behind our backs) and rate_tier must be present. Verified against the real API -- tokens_reasoning=0, rate_tier=off_peak, 3.9s round trip.

能放什么
跨所有域复用、且不含任何业务判断的东西。
不能放什么
- 任何业务规则。「配额够不够」属于
packages/domain/billing， 「任务能不能取消」属于packages/domain/task。放进来就没人能纯单测了。 - 对具体业务域的 import。
shared在依赖层级的底部，反向依赖会立刻形成环。
日志脱敏不是可选项
logging.py 的脱敏是 structlog 处理器，作用于每一条日志，没有 opt-in。
新增敏感字段时加进 SENSITIVE_KEYS，或用 LOG_EXTRA_REDACT_KEYS 环境变量。
NFR-SEC-03 / 架构 §11.2：手机号、UnionID、图片地址、诊断结论、令牌一律脱敏。
新增错误码
在 ErrorCode 加值，同时在 ERROR_META 加 message 和 hint。
测试 test_every_error_code_has_metadata 会强制这一点。
FR-BILL-07：配额相关文案里不能出现价格、购买、会员、升级字样，
test_quota_hint_never_mentions_price_or_purchase 会扫描全部文案。
