+# Default cutover: reconciled implementation frontier
+
+- Baseline: `d64c4d377` on `main`, 2026-09-24; open PR states are a snapshot, not merge promises.
+- Owners: overall roadmap #4574 R5/G2; shared authority L2–L9/D1–D3; TS migration T1–T4.
+- Delivery: complete source transport through existing typed projection and shadow management owners.
+- This checkpoint supersedes numerical remaining-PR estimates in earlier delivery entries.
+
+## Correct the accounting
+
+The previous “5–8”, “6–8” and “7–9” numbers counted broad work packages as
+remaining PRs, then retained the estimate after parts landed and additional
+prerequisites appeared. They are not an audited PR backlog and are withdrawn.
+A code gap, an open PR, integration acceptance, an elapsed-time qualification
+and a maintainer cutover decision are different units. Do not add or decrement
+them as though they were interchangeable PRs.
+
+| Evidence at this baseline | Current disposition |
+| --- | --- |
+| #4870 claim-preserving writes; #4888 reviewed cutover; #4920 drain planning | Implemented. Exercise their combined head; do not commission replacements. |
+| #4922 complete canonical snapshot pagination; #4960 qualified SQLite runtime admission; #4961 display refresh recovery; #4964 shared source summaries | Implemented. Consumer and packaged-client acceptance still needs integration evidence; a whole new pagination/recovery implementation is not pending. |
+| #4967 typed complete-source assembly; #4968 native outbox delivery/recovery | Implemented. Large source RPC failure below is a separate demonstrated gap, not absence of capture assembly. |
+| #5003 atomic event-owned completion | Open. Solves batch publication/retry, **not** the event writer's shadow-capture binding. |
+| #4994 explicit leased Agent handoff; #4995 generated Monitor proof; #4991 rejected poll reservation; #4992 deferred receipt-bound Turn | Open. Integrate their exact reviewed heads before deciding what caller work remains; do not recreate them under a new caller-refactor PR. |
+| #4931 retained SQLite proof encoding, contributor #4224 | Open optimization plus incomplete D2 qualification. A speedup is not capacity/recovery/soak acceptance. |
+| #4915 default `.loopx` filesystem placement | Separate configuration migration; does not select File/SQLite authority. |
+
+There are six relevant open implementation PRs above (#5003, #4994, #4995,
+#4991, #4992, #4931), plus the separately classified #4915 to avoid conflating
+filesystem placement with authority. These are not six unstarted requirements,
+nor a claim that every one is a mandatory storage-default dependency.
+
+## Four concrete next delivery boundaries
+
+These are **four proposed new batches including this delivery**, in addition to
+integrating existing work. They are not a guaranteed total remaining PR count.
+The command inventory and exact-profile acceptance can reveal further defects;
+record a new demonstrated gap rather than silently keeping a range unchanged.
+
+| Batch | Observable result and owning boundary | Exit and remaining dependency |
+| --- | --- | --- |
+| A. Complete source pipeline (this delivery) | A source larger than the RPC envelope can pass typed projection, bootstrap, writer capture, inspect, qualify and reviewed promotion without truncation. Python transports bytes; TS retains source admission and authority. | Large real CLI journey; File/SQLite complete reads; source-witness rejection; detached real-source rehearsal. Does not bind the event writer or qualify a provider default. |
+| B. External-effect executor fence | Current execution proof protects the actual external-effect interval, including takeover, timeout, exit and uncertain completion, using the existing lease/effect owners. | Stale executors cannot execute or settle fenced work; exact receipt recovery. #4994/#4995 caller integration is reused; a point-in-time proof check alone is insufficient. |
+| C. Event-writer binding and whole-Goal migration/rollback | Bind the actual event writer lock/publication lifecycle to the existing outbox lineage, then exercise mixed Markdown/event/lease writers, drain, reviewed cutover, canonical consumers and fenced export/rollback as one journey. Retire replaced Python decisions at their TS owner. | Integrate #5003 rather than reimplement atomic completion. Preserve `event_log_writer_not_bound` until the real binding passes. D1 consumers, command inventory and D3 cohort evidence must close; if this requires separate code, name the discovered boundary explicitly. |
+| D. Default/onboarding and final bounded Python retirement | Qualified local profile is selected consistently by new Goal creation, settings, installation and packaged frontend/Lark/CLI; existing Goals follow explicit migration/disable guidance. Delete only business writers whose callers have switched. | B/C and applicable D1–D3 evidence, rollback and entrypoint readback. Keep permanent Python rendering, host IO and legal import/export. |
+
+D2 capacity, crash/restore/upgrade/runtime coverage and **at least ten days of
+natural elapsed soak** are evidence gates on an exact SQLite profile, not an
+assumed one- or two-PR allocation. #4224 retains ownership. D3 integration and
+owner-approved cohort cutover are also not automatically new PRs. No fixed
+completion date or exact total PR count is defensible while these are open.
+A File-only bounded cutover, a qualified SQLite default and migration of every
+existing Goal have distinct acceptance scopes; none proves the other two.
+
+PostgreSQL reuses the typed commands and AuthorityStore, while deployed
+transport, authentication/tenant policy, restore identity, operations and
+capacity qualification remain its separate medium-term path. Local default
+does not wait for PostgreSQL deployment; a passing conformance suite does not
+establish production service readiness.
+
+## Complete-source transport and budget decision
+
+At this baseline `test_canonical_snapshot_integration` fails before provider
+admission: complete source projection exceeds the 2 MiB request limit. Paging
+canonical reads already exists, but source capture and management still send
+whole projections. Trimming source records would invalidate digests and parity;
+increasing the generic RPC budget would enlarge every method's exposure.
+
+The existing coordination contract generates both schema names and the byte cap
+for Python and TS. Python file exchange stays in its existing source projection
+adapter; there is no independently maintained same-name Python/TS module pair.
+Only source-bearing handlers accept a private host-local transfer envelope.
+Python writes a temporary request; TS verifies its method, byte length, SHA-256,
+regular-file identity and private directory, then invokes the same handler.
+TS writes an exclusively created result and returns a small bound receipt;
+Python verifies the response bytes and cleans up temporary files on both success
+and failure. Inline callers remain compatible. These artifacts are transient
+transport, not another authority store or durable business receipt.
+
+The RPC limit remains 2 MiB. **The new artifact limit is 16 MiB per request or
+result**, a separate explicit bound, not unlimited streaming or an assertion
+that all goals fit. Oversize input rejects before execution. Result delivery can
+fail after a mutation; callers must recover using the existing operation identity,
+never infer that an RPC error means no commit. No automatic mutation retry is
+added. Memory still includes complete parsed objects; this does not solve
+arbitrarily large provider history or capacity qualification.
+
+The cap accommodates the multi-megabyte complete-source fixture and source
+management's repeated representation while keeping allocation bounded. In 32
+interleaved warm calls of the same small source on the same host, inline versus
+artifact median was 9.15/11.62 ms and p95 11.60/15.93 ms. This measured local IO
+cost is accepted for complete-source calls; it is not a global latency claim.
+Future size changes require a measured workload and the existing budget review.
+
+Validation uses real File/SQLite and a disposable PostgreSQL 16 server. The
+large CLI regression qualifies and promotes only a synthetic isolated Goal.
+A live source rehearsal that detected concurrent changes was discarded; the
+accepted real-source rehearsal verifies a detached copy against its capture
+witness and exercises all mutations there. Private sources, identifiers and
+raw output are excluded from public artifacts. No active Goal is promoted.
+
+No frontend settings or API shape changes are needed: the same CLI and Python
+management adapters invoke the same domain handlers and return the same results.
+The public change is that supported complete-source operations no longer fail
+solely because their source crosses the RPC envelope. Defaults, authorization,
+source freshness, event-writer holds and provider promotion criteria are unchanged.
+
+A related runtime repair handles socket errors when a caller closes an oversized
+response before draining it. One disconnected caller no longer crashes the
+shared runtime; the regression asserts that subsequent paged reads retain the
+same process identity. It neither cancels nor retries the business operation.

+# 默认切换：按实现证据重算交付边界
+
+- 核对基线：2026-09-24 `main` 的 `d64c4d377`；开放 PR 状态是快照，不是合入承诺。
+- 归属：总目标 #4574 R5/G2；shared authority L2–L9/D1–D3；TS 迁移 T1–T4。
+- 本次交付：既有 typed projection 与 shadow management 的完整来源传输。
+- 本检查点取代此前交付记录中的剩余 PR 数量估算。
+
+## 先纠正统计口径
+
+此前“5–8”“6–8”“7–9”把宽泛工作包写成剩余 PR 数，部分实现合入、额外前置项
+出现后又维持原估算。这些数字不是逐项核对过的 PR backlog，现撤回。代码缺口、
+开放 PR、集成验收、自然时间资格和维护者晋升决定是不同单位，不能相加或机械扣减。
+
+| 当前基线的事实 | 现在应如何处理 |
+| --- | --- |
+| #4870 保留 claim 的写入、#4888 reviewed cutover、#4920 drain 规划 | 已实现。验收组合 head，不再重新安排一套替代实现。 |
+| #4922 完整 canonical 快照分页、#4960 SQLite runtime 准入、#4961 显示刷新恢复、#4964 共享来源摘要 | 已实现。消费者和打包客户端仍需组合验收，不等于还缺一个全新的分页/恢复实现。 |
+| #4967 TS 完整来源组装、#4968 原生 outbox 交付/恢复 | 已实现。下述大型来源 RPC 失败是另一个已复现缺口，不能称为 capture 组装未做。 |
+| #5003 event-owned completion 原子提交 | 开放。解决整批发布/重试，不负责 event writer 与 shadow capture 的绑定。 |
+| #4994 带 lease 的显式 Agent 交接、#4995 Monitor 命令 proof、#4991 拒绝 poll 后释放预约、#4992 延期且绑定 receipt 的 Turn | 开放。组合各自经过评审的 head 后盘点 caller，不能再开一个 caller 重构 PR 重做它们。 |
+| #4931 SQLite retained proof 编码、contributor #4224 | 优化 PR 开放，D2 资格未闭合。提速不等于容量、恢复和 soak 验收通过。 |
+| #4915 默认 `.loopx` 目录 | 独立的配置迁移，不会选择 File/SQLite authority。 |
+
+上表有六个相关的开放实现 PR（#5003、#4994、#4995、#4991、#4992、#4931），
+另列 #4915 排除目录迁移造成的混淆。它们不是六个尚未动手的新需求，也不宣称每个
+都是 storage default 的硬依赖。
+
+## 四个可明确描述的后续交付边界
+
+在整合已有工作之外，规划以下**四个新增交付批次，包含本次**。这是下一步开发
+安排，不是保证总共只剩四个 PR。命令清单和精确 profile 的验收仍可能发现缺陷；
+届时记录新证据和新边界，不再悄悄维持一个范围数字。
+
+| 批次 | 可观察结果与 owner | 退出证据及剩余依赖 |
+| --- | --- | --- |
+| A. 完整来源流水线（本次） | 大于 RPC envelope 的来源可完整经过 TS projection、bootstrap、writer capture、inspect、qualify、reviewed promotion。Python 只传字节，TS 保留来源准入及 authority。 | 大型真实 CLI 链路、File/SQLite 完整读取、source witness 拒绝反例、真实来源隔离副本演练。不绑定 event writer，也不宣布 provider 默认合格。 |
+| B. 外部 effect executor fence | 复用 lease/effect owner，在真实外部 effect 执行区间保护当前 execution proof，覆盖接管、超时、退出与不确定完成。 | 过期 executor 不能执行或结算被围栏的工作，精确业务 receipt 可恢复。复用 #4994/#4995；执行前查一次 proof 不足以证明整个区间安全。 |
+| C. Event writer 绑定与整 Goal 迁移/回滚 | 将真实 event writer 的锁及发布生命周期接入现有 outbox lineage，组合 Markdown/event/lease writer、drain、reviewed cutover、canonical 消费者和 fenced export/rollback。随 TS owner 收口删除替代的 Python 决策。 | 整合 #5003，不重做原子完成。真实绑定通过之前保留 `event_log_writer_not_bound`。闭合 D1 消费者、命令清单与 D3 cohort 证据；若发现需要独立代码批次，明确记录该缺口。 |
+| D. 默认/onboarding 与最后一批有界 Python 退役 | 新 Goal、settings、安装和打包 frontend/Lark/CLI 一致选择合格本地 profile；已有 Goal 有显式迁移、停用指导。仅删除 caller 已切换的业务 writer。 | B/C、适用的 D1–D3、回滚及受影响入口读回。保留永久 Python renderer、宿主 IO 和合法 import/export。 |
+
+D2 的容量、crash/restore/upgrade/runtime 覆盖和**至少十天自然经过时间的 soak**，
+是精确 SQLite profile 的证据门，不预设为一个或两个 PR；#4224 继续拥有这项工作。
+D3 集成和经 owner 批准的 cohort 切换也不自动产生新 PR。这些缺项未闭合前，不给
+固定完成日期或精确总 PR 数。File-only 有界切换、合格的 SQLite 默认、所有存量
+Goal 迁移是不同验收范围，不能互相证明。
+
+PostgreSQL 复用 typed command 和 AuthorityStore，部署 transport、认证/tenant
+策略、restore identity、运维和 capacity 资格仍是独立中期路线。本地默认不等待
+PostgreSQL 部署，conformance 通过也不等于生产服务已合格。
+
+## 完整来源传输与预算决定
+
+此基线的 `test_canonical_snapshot_integration` 在 provider 准入之前失败：完整
+来源投影超过 2 MiB request 上限。canonical 读取分页已实现，但 source capture
+及管理命令仍传完整投影。裁剪来源记录会破坏 digest/parity；扩大通用 RPC 上限会
+影响所有方法。
+
+协议名称和字节上限由既有 coordination 合同统一生成给 Python/TS。Python 文件交换
+留在现有来源投影适配器，不新增独立维护的同名 Python/TS 模块对。
+仅携带来源的 handler 接受本机私有文件 envelope。Python 写临时 request；TS 核验
+method、字节数、SHA-256、普通文件身份和私有目录，然后调用原有 handler。TS 排他
+创建结果文件并返回紧凑的绑定回执；Python 校验结果字节，在成功和失败时均清理临时
+目录。inline 调用继续兼容。这是临时传输，不是第二套 authority store 或持久业务 receipt。
+
+RPC 保持 2 MiB。**新增 artifact 对单次 request/result 分别限制为 16 MiB**：
+这是单独的明确容量边界，不是无限流式，也不保证任意 Goal 均可容纳。超大输入在执行前
+拒绝；结果交付失败可能发生在业务提交之后，调用方必须按原 operation identity 恢复，
+不能把 RPC 失败当成未提交。本次不添加自动 mutation 重试。内存仍包含完整解析对象，
+不解决任意大的 provider 历史或容量资格。
+
+16 MiB 容纳多 MiB 完整来源 fixture 及管理请求中的重复表示，同时限制分配规模。
+同机、同小型来源、32 对交错 warm 调用：inline/artifact 中位数为 9.15/11.62 ms，
+p95 为 11.60/15.93 ms。本次为完整来源调用接受该实测本地 IO 成本，不宣称全局延迟
+结论。后续调整大小仍需实测 workload 和既有预算审查。
+
+验证使用真实 File/SQLite 及一次性 PostgreSQL 16 server。大型 CLI 回归仅对合成隔离
+Goal 进行资格验证和晋升。本机活跃来源的一次演练检测到并发变化，已丢弃证据；被接受
+的真实来源演练先按 capture witness 验证隔离副本一致性，再仅在副本执行变更。私有
+原文、标识和原始输出不进入公开产物，没有晋升活跃 Goal。
+
+无需新增前端设置或改变 API 形状：既有 CLI/Python 管理适配器仍调用同一领域 handler、
+返回同一结果。公开变化是完整来源不再仅因越过 RPC envelope 而失败。默认配置、权限、
+source freshness、event writer hold 和 provider 晋升标准保持原有语义。
+
+相邻 runtime 修复处理客户端未读完超大响应就断连时的 socket 错误，避免一个断连
+导致共享 runtime 退出。回归验证后续分页请求仍使用同一进程；不取消或重试业务操作。
