+# 006: Intercompany positions, subject review and drill-down evidence (B-44)
+
+Status: accepted (2026-08-19)
+
+## Decision
+
+The intercompany ledger adds one canonical layer above B-43's eligible events:
+
+- **Append-only ledger events.** A canonical `ledger_event` carries an
+  append-only `ledger_event_revisions` chain. A B-43 eligible bank event first
+  becomes a `pending_subject` revision; an administrator confirms the subject
+  into a `confirmed` revision. Corrections are never in-place edits — a
+  reversal or adjustment is a *new* ledger event with its own effective date,
+  and the original event keeps its history so earlier cutoffs are not
+  rewritten.
+- **Manual records as immutable submitted facts.** Companies submit
+  `manual_records`; only an administrator-approved record becomes a confirmed
+  ledger event (`approve_new`) or joins one (`approve_link`). Returned,
+  exception and pending records never affect a balance and never leak to the
+  counterparty. Approved facts change only through `reverse` (a new opposite
+  event) — the original is never edited.
+- **One perspective, fixed mirror.** Subjects are stored from one participating
+  company's perspective (`receivable/payable/other_receivable/other_payable`);
+  the other side is the fixed mirror (应收<->应付, 其他应收<->其他应付), so the
+  two companies can never book conflicting subjects.
+- **Subjects are confirmed, never auto-posted.** Bank summary/purpose text only
+  feeds a deterministic *suggestion* dictionary (`subject-suggest-draft-v1`,
+  not group-approved). Without an approved trade dictionary every bank event
+  stays in subject review until an administrator confirms.
+- **Decimal-only aggregation.** All money is stored as TEXT decimal strings and
+  aggregated with Python `Decimal`. SQLite `SUM`, JavaScript `Number` and
+  Python `float` never touch financial math. Different currencies are
+  aggregated and displayed separately; nothing is converted to a group total.
+- **Conservation is asserted.** For every company pair and currency the two
+  perspectives must mirror exactly (`C_A == -C_B`); a violation raises a
+  calculation exception instead of rendering an unbalanced number.
+- **Unresolved is absolute gross.** Unresolved amounts are summed by absolute
+  value per currency (never netted), broken down by reason
+  (`subject_review`, `unmatched_single`, `manual_pending`), with count and
+  gross amount exposed on every balance response.
+- **B-45 boundary.** Until the B-45 opening balance exists, every response
+  returns `opening.status=unavailable`, `opening.amount=null` and
+  `result.kind=period_net_change`; the UI labels this "期间净变动", never
+  "期末余额".
+
+## Background
+
+B-43 produces `eligible_intercompany_events` as the only bank-event entry
+point. Before B-44 there was no canonical financial event, no statutory
+subject, no manual-record approval, and no server-side balance API. The
+revision-chain design is inherited from `transfer_match_decisions` in
+migration 5 and from the append-only audit posture of the rest of the system.
+
+## Consequences
+
+- **Positive:** balances are deterministic, conservable, auditable and
+  drillable from a group directory down to bank source rows; manual records
+  cannot double count; corrections never mutate evidence; company portals are
+  tenant-scoped on the server.
+- **Negative:** pending bank events and returned/exception manual records are
+  intentionally invisible to counterparties, which can surprise cashiers who
+  expect symmetric disclosure; subject confirmation is manual until a
+  group-approved dictionary exists.
+- **Operational:** migration 6 is forward-only for production once
+  approvals/revisions exist; pre-production it can be rolled back with
+  `--rollback-to 5`. Read aggregation runs against the rebuildable current
+  projection (no day snapshots yet); if B-45 monthly close needs them, immutable
+  monthly snapshots can be added behind the same API contract.
+
+## Files
+
+- `src/bank_importer/ledger_events.py` — event lifecycle, revision chain,
+  bank reconciliation, reversal/adjustment/reopen, projection rebuild.
+- `src/bank_importer/subjects.py` — subject constants/mirror, suggestion
+  dictionary, `confirm_subject`.
+- `src/bank_importer/manual_records.py` — submission, approval
+  (new/link), return/exception/reverse, candidate hints, idempotency.
+- `src/bank_importer/positions.py` — Decimal aggregation, directories, pairs,
+  events, evidence visibility, unresolved buckets, keyset pagination.
+- `server.py` — `/api/admin/intercompany/*` and `/api/company/intercompany/*`
+  plus `/api/admin/subject-reviews` and `/api/admin/manual-records`.
+- `db.py` migration 6 — `manual_records`, `manual_record_decisions`,
+  `ledger_events`, `ledger_event_revisions`, current-pointer projections,
+  source claim tables, `ledger_subject_suggestions`, `eligible_position_events`.
+- Tests: `test_ledger_events.py`, `test_manual_records.py`,
+  `test_positions.py`, `test_positions_api.py`, extended
+  `test_persistence.py`.

+- 已实现规范转账事件和双边流水匹配。匹配决定保留历史，无法自动判断的记录进入人工审核；同公司调拨、外部流水和未锁定的单边记录不进入已确认的公司间往来。
+- 已有登录页、总账端和公司端页面，最近一次合并完成了登录页视觉改版。

+# 项目需求
+
+## 这个系统做什么
+
+这是河南金牛实业集团有限公司内部各公司之间的资金往来管理系统。它把各公司的银行流水集中起来，识别同一笔公司间转账的两边记录，形成可以一路查回原始银行流水的往来结果。
+
+系统有两个独立入口：
+
+- 总账管理端：管理公司、公司账号、银行账户、导入记录、异常和公司间转账匹配。
+- 公司出纳端：只处理本公司的账户登记、流水上传、工作表确认和本公司相关异常。
+
+## 必须做到的业务规则
+
+- 银行原始文件和原始流水是证据，导入后不能直接修改或删除；修正必须通过可追溯的审核决定、冲销或调整完成。
+- 一笔公司间转账的收、付两边只能算作一个经济事件，不能因为有两条银行流水就重复计算。
+- 同一家公司不同银行账户之间调拨，不计入公司间往来。
+- 账号、金额、方向、日期和余额等可核对信息优先于户名；信息不完整或有歧义时进入异常审核，不能猜。
+- 已确认金额和待确认金额必须分开；所有余额都要说明统计截止日期和未决金额。
+- 公司用户只能查看、上传和导出本公司的数据。这个限制由服务端执行，页面上“看不见”不等于有权限限制。
+- 起算日前的流水必须保留，但不参与期内计算；期初余额、流水覆盖断档、无业务校准、月结和调整都要留痕。
+
+## 当前技术边界
+
+项目使用 Python 标准库服务、SQLite 数据库和浏览器页面。银行模板支持 `.xls` 与 `.xlsx`，按表头识别而非依赖固定行列。金额使用精确十进制，真实运行数据放在 `data/`，不进入代码仓库。
+
+系统目前仍是测试环境项目，不能当作已完成生产部署：正式上线前仍需补齐核算、期初与断档、月结、备份、监控和 HTTPS 等能力。

+Bank source rows and approved manual records are immutable evidence. This
+module turns them into one canonical ledger event each through ``reconcile_*``
+functions and an append-only revision chain. Corrections are never in-place
+edits: a reversal or adjustment is a new ledger event with its own effective
+date, and the original event keeps its history so no earlier cutoff is
+rewritten. Current revisions and source claims are rebuildable projections.
+
+Only B-43 ``eligible_intercompany_events`` feeds bank facts here; same-company
