+# 手工观察主时钟接入候选
+
+2026-09-14，未发布，完整Goal不关闭。不是生产手工影子回放验收。
+
+## 本阶段已实现
+
+- BacktestEngine可显式绑定严格v2手工观察输入。原始回报时刻驱动账本；同一时刻按真实观察序号逐笔原子应用，回调能看到100、200而不是第一笔就看到两笔总量。
+- 默认盘前、开盘、盘中、收盘/结算及当日晚到回报纳入处理；跨会话观察先于下一会话公司行为，不生成行情行；结束后仍未覆盖的观察明确失败，不截断成成功。
+- 手工成交写独立来源及应用明细，不冒充模拟策略FillEvent。账户变化不计作出入金；手续费只扣一次，最终费用来源/时间仍单独保留。
+- 股数及现金改变后通知策略，真实买卖日期更新持有保护和卖后禁买证据；券商模拟器的当日卖后禁买规则同样接收手工卖出，不把手工绕过自动条件理解为抹掉真实成交历史。
+- 分钟时钟不必依赖策略订阅或同一时刻市场报价，手工价格也不会伪造为市场行情。已有挂单/待执行目标冲突仍明确拒绝，不替用户撤单或重建目标。
+- 流式数量、原始观察明细及换手率纳入手工应用；纯无成交的来源不会改变自然策略时钟。
+
+## 已复现并修正的问题
+
+旧默认OpenAuction回调在09:31，接着却可能执行09:30日内步骤。手工09:27观察会由此先进入09:31再倒退到09:30。已把默认开盘阶段放在09:25，并保留显式调度时间。
+
+盘前08:50/09:10规则原来在同一状态上顺序计算，不能正确看到夹在两者之间的08:55回报。现按实际到期时间交错处理回报、调度、资金等指令和撤改控制；盘前阶段若跨越开盘阶段，明确报告冲突，不把晚时点状态带回早时点。
+
+## 当前验证
+
+Core872通过（9项原ignore不计通过），交易工作区619普通测试通过；不是实际券商行情验收。此前默认阶段样例最终600股、现金3991、权益9991、出入金0，原四个基础用例保留。
+
+本轮新增8项回归，不重复把基础样例当新验收：
+
+- OpenAuction 09:20/09:26、AfterTrading 15:15/16:00、Settlement 16:10与09:22/15:30/16:05手工观察交错。原候选09:20提前读到100股，16:00/16:10仍只读到100股；修复后依次为0/100/100/200/300股。
+- 盘后16:00的100股与结算16:10的200股显式指令，下一交易日各执行一次、共300股，信号日价格10不冒充执行日价格12。lag0/lag1保留原信号日、意图创建日和实际成交日；测试还抓到立即成交记录曾被统一注释为新信号日，已按批次原始日期记录。
+- 多个完整目标在进入待执行队列时就只保留最新一份；次日新的0%完整目标不会先执行旧买入。显式股数指令不作为完整目标覆盖。
+- 结束日期的两笔显式意图没有生成委托/成交，完整原指令留在terminalAudit；完整目标只留最新一份。NaN/Inf不能在JSON中被悄悄变成null。
+- 存在真实行情/风控但没有新因子选股快照的下一交易日，仍执行已有指令，不等到后日再运行。声明盘后阶段的策略使用完整市场日历，外部指标可用同一`backtest_execution_dates_with_rules`对齐；当前Runner的Platform策略只暴露OpenAuction/OnDay/Minute，不宣称已支持配置盘后阶段。
+- 显式开盘调度越过已配置执行窗口被拒绝；盘后GTC撤单立即作为控制执行，不变成次日新委托。
+
+盘后处理使用正常账本/报价/风控入口，不创建模拟外部Fill，不越过结束日期。旧DAY订单仍按到期失效，下一日处理的是尚未提交的策略意图，并非延长旧订单有效期。无新信号的报价时钟复用有序迭代器，不复制整日Tick列表。
+
+结果协议和API/Runner的候选接入见fidc-backtest-service/docs/manual-execution-run-contract-20260914.md。当前正常记录/费用原始精度不改；所有新代码尚未发布，影子调用仍没有解除四类纯比例拒绝门禁。
+
+## 必须继续
+
+1. 本轮已覆盖上述显式阶段与跨日用例；仍需补完整混合时钟矩阵，特别是显式开盘晚于盘中报价/ETF开盘、无新信号日同时有ETF待执行目标、公司行为和跨日保护组合。不得修改market_open已有09:31语义或把这些未验组合静默跳过以让测试通过。
+2. 完成影子调度调用、所需历史证券范围、来源权限/归属、实际HTTP和Linux验收；不以独立输入/结果单测冒充端到端。
+3. 结果委托/成交分页接口与统一UI仍须合并展示外部手工来源，保留未知组件和完整原始ID，不把仅落库视为呈现已完成。
+4. 核对GT正式总费用来源、整仓关键日志严格持久化及完整参数矩阵后再配套发布。
+
+本轮未重启生产或发送委托。同期其他维护已将Backtest发布为Engine665653c/Service501f6d0；这不包含本文件所述主时钟候选。交易仍166998d/v2026.9.14.6，Source d5/PID1700096冻结与研究暂停不改。

+## 2026-09-14 运行级仓位配置补充
+
+v3 手工输入独立携带审计仓位/权重时间线与旧日级前缀，不覆盖原策略或股票池。仅已成交证券产生独立行情需求；补充范围不会成为选股候选。恢复跟随回到原规则，未来事件不能被伪称为截止时刻前已观察事实。Core 878 项本机通过，尚未部署；PG、期间隔离、权限与剩余联合验收见 `../../fidc-trading-platform/docs/shadow-manual-input-20260914.md`。本节不替代前述时钟证据，也不宣称全部矩阵完成。

+- 游标按真实观察时间和已持久化事件序号前进，重入同一时点不会重复入账，时间倒退或越过证据截止时间会失败。
+- 资金、持仓及游标在一次advance中原子变更。资金不足、T+1、生命周期冲突或活动影子订单冲突不借股、不借款、不取消原订单，也不留下半笔状态。
+- 人工交易不是出入金，不更改现金流中性单位或初始资金；原始买卖账本入口继续使用原有计算，仅抽出可传固定金额的内部函数。

+
+Live整仓的历史审计原来只有confirmation_hash，执行ID在另一个开始事件中；当前候选已将服务端生成的execution_id和所选account_id写入同一仓位审计详情，并校验非空ID和账户范围。旧历史仍只能依据原始审计/事件做唯一关联，不能猜测或重写。

+# Exact Series Column Storage
+
+## Status
+
+The subsequent business-main merge includes the separately published 81acc54
+clock/callback fixes and 5e11f3d manual-replay foundation. The combined version
+passed 857 core, 448 runner and 119 API tests, six long reference replays and
+three additional strategy replays;
+see `/Users/boris/WorkSpace/fidc-backtest-service/docs/arrow-factor-scratch-rejection-20260914.md`.
+The scratch candidate from that experiment was removed. Series storage is
+now published to Backtest only in the combined 665653c/501f6d0 release below;
+existing measurements retain their original versions.
+
+The original twelve real long replays preserve their independent
+business baselines and reduce peak RSS by about 9.5%. Construction latency is
+mixed, including a reversed pair where the control is faster. This is accepted
+as evidence of a smaller working set, not as a proved general speedup or closure
+of the main performance objective. Original results are retained unchanged.
+
+The Source implementation remains d5b682c6d09704ff23d725a8dd8b155db3eb6967.
+Research/signal work remains paused. The initial experiments ran while e81bf47/c98
+was published; later business work published e81bf47/81acc54. This performance
+task did not restart Source, trading or another user's process. The original
+clock counterexample was resolved by that business work; complete manual-replay
+integration remains open and is not proved by these performance tests.
+
+## Separate DayOpen Correction
+
+Code inspection found that PriceField::DayOpen selected the Open prefix sums,
+although direct history access returned day_open. For day_open values 10/12
+and open values 20/24, that path computes 22 instead of the expected 11.
+The correction adds its own day-open prefix and a regression checking both
+fields plus empty/insufficient windows. No price field is substituted.
+
+This correction was built and tested independently before the storage change:
+806 core unit/integration tests, 448 runner tests and 119 API tests passed.
+The resulting control runner is
+8859459f54389f12af1ab7d4e36802c01aff63fb10fbb679243ccdd54d013e2d.
+It also preserves the real rotation baseline. Both subsequent A/B variants
+include the fix, so corrected calculation semantics are not counted as speedup.
+
+## Storage Design
+
+SymbolPriceSeries previously allocated separate vectors for last/bid/ask,
+their prefix, timestamps, trading phases and three quote-volume fields, even
+when actual data repeated or exactly matched the existing close series.
+
+- ReferenceMatchedValues aliases the existing column only after every consumed
+  value matches by f64::to_bits. A mismatch materializes the exact preceding
+  values and continues as an owned vector. No missing/invalid price is replaced
+  by close; signed zero and NaN payload differences prevent sharing.
+- RepeatedValues retains the actual first value and logical length. It avoids
+  expanding equal values, including nonzero volumes and Some strings. The
+  first difference materializes the exact prior values. None is distinct from
+  an empty string; no value is inferred from the backtest frequency.
+- Intraday updates materialize only changed columns. Cloned views retain their
+  original values and immutable daily base. Last-price prefix sums use the same
+  accumulation order and actual values as before. History cutoffs are unchanged.
+
+There is no new dependency, unsafe code, strategy-specific branch, disk schema,
+source-data rewrite or account/result sharing. Construction and data validation
+remain in the existing paths. The overlay comment now accurately states that
+quote fields affect Last history while daily OHLC remains unchanged.
+
+The full candidate passes 813 core unit/integration tests (9 ignored), 448 runner
+tests (9 ignored) and 119 API tests (5 ignored). New tests cover exact bit
+identity, distinct zero/NaN values, repeated nonzero/string values, mutation
+isolation, unknown dates, full snapshot equality and history-date cutoffs.
+These tests do not prove the separately known same-day execution-clock issue.
+
+## Real A/B
+
+All cases execute 2021-08-23 through 2025-11-17 with their unchanged frozen
+strategy/runtime/bundle and 10,000,000 initial cash. This is not five complete
+execution years. Every run is a new process with private result artifacts and
+the same verified shared inputs: 9,257 files / 12,596,608,049 bytes. No original
+input changed and no Arrow/bin input was newly created. Hashing is outside the
+runner timer; no result is reused. Source/OS caches are not cold.

+The final rotation pair deliberately ran candidate before control. Rotation
+RSS medians are 7,138,628 versus 6,457,728 KiB, about 665 MiB / 9.5% lower.
+Other strategy pairs save about 670-673 MiB. These are measured process peaks,
+not estimates obtained by adding cgroup limits or counting mmap as private RAM.
+
+Construction medians are 1.901 versus 1.853 seconds for rotation. The first pair
+has a larger reduction, but other samples and the reversed pair do not support
+a universal 16% construction or total-latency claim. Source validation waits and
+independent phase variation remain in the full evidence. A read-only host sample
+showed load near 49 and thermal readings 53/58/69 C; it does not prove the cause
+of timing variation. No host policy or another user's workload was changed.
+
+All six canonical sections and result-store SHA match the appropriate existing
+baselines: 21,393 / 29,776 / 31,862 / 51,300 fills. Result and request evidence,
+physical manifests and all 3,506 fact blocks were verified. No earlier failed
+or successful receipt was rewritten. Complete receipts remain on 177; only the
+compact verified summary is stored here to avoid duplicating input inventories.
+
+## Remaining Work
+
+Do not publish this as the main performance fix. Next, target the remaining
+daily snapshot/factor construction and direct typed-column reuse, avoiding
+new per-access branches or post-hoc compression passes. Cold-query acceptance,
+real minute-mode acceptance remain outstanding for this storage change. The
+combined version subsequently passed daily HTTP publication below. The original
+clock issue was fixed by subsequent business
+work, not this experiment. Signal lifecycle, financial PIT and UI factor conditions
+remain outside this completed storage experiment.

+## Combined Release
+
+Engine 665653c / service 501f6d0 passed 860 core, 448 runner and 119 API tests,
+six additional independent-process replays and nine post-publication HTTP runs.
+Complete canonical/store results remain equal to each strategy's own baseline.
+An adjacent original/new rotation pair measures 15.279/14.579 seconds and
+6,923,640/6,369,900 KiB peak RSS, but the default-window HTTP means are essentially
+unchanged (13.646/13.740 seconds). Reduced memory and conditional cross-window
+reuse are not promoted to a universal latency improvement.
+
+The official Backtest-only publication preserves Source d5, paused research,
+trading services and execution permissions. Its active build root
+/srv/fidc/canonical/build/factor-reserve-20260913 must not be overwritten or
+reused. Shared DataSet acceptance proves input reuse while distinct strategies
+execute independently; no results are cached. Identities and original receipts:
