+# Agent Note: Case-insensitive path round-trips in test expectations

+## Problem
+
+[`packages/session/session-persistence-jsonl/tests/jsonl.spec.ts`](../../../../packages/session/session-persistence-jsonl/tests/jsonl.spec.ts) proves that a relative `root` is resolved before a session is located. It handed the plugin `relative(process.cwd(), absoluteRoot)` and built its expectation from `resolve(absoluteRoot)` — two different starting points for the same directory.
+
+On a case-insensitive filesystem those starting points can disagree on spelling. `path.relative()` on Windows compares case-insensitively and returns a path with the shared prefix removed, so the casing of that prefix is gone; `path.resolve()` then rebuilds it from `process.cwd()`. When the prefix `tmpdir()` and `process.cwd()` share is spelled with different casing in each, the plugin's resolved root carries the `cwd` spelling while the expectation carries the `tmpdir()` spelling, and `toEqual` compares two strings that name the same file.
+
+A host reaches that state when `tmpdir()` and `process.cwd()` share a path prefix but spell it differently — for example when `TMP` is mapped into the runner work tree under one spelling while the workspace path uses another. Sharing the tree is not enough on its own: if both spell the prefix alike, the round-trip returns the same string. The case fails there and passes everywhere else, which reads as a flake rather than as a fixed disagreement between two spellings.
+
+## Decision
+
+The expectation resolves the same relative root the plugin receives. Both sides pass through one `resolve(cwd, relative)` call, so the case-insensitive round-trip cannot place two spellings on the two sides of the comparison.
+
+This is a test-only change. The platform treats both spellings as the same file, so storage behaviour does not depend on which spelling `resolve()` produces. The string itself stays observable: hook payloads carry it as `transcript_path` and the shell contributor exports it as `DSH_SESSION_JSONL`, so a consumer that compares those strings can still see the difference. Composition fixtures such as [`apps/cli/tests/profiles/headless/tests/fixtures/cli.cordis.yml`](../../../../apps/cli/tests/profiles/headless/tests/fixtures/cli.cordis.yml) set a relative session root — but the plugin resolves whatever it receives before use, so a relative root reaches disk as one spelling rather than two.
+
+The case still asserts what it names: with the plugin's `resolve(config.root)` reduced to `config.root`, so a relative root is no longer resolved, the case fails.
+
+The neighbouring decision about constructing paths with the host `node:path` API lives in [cross-platform test fixtures](2026-07-22-cross-platform-test-fixtures.md); this note covers a different mechanism, the `relative()`/`resolve()` round-trip under a case-insensitive filesystem.
+
+## Alternatives considered
+
+**Compare the two paths case-insensitively.** This keeps the assertion green on the affected runners but accepts a real configuration disagreement as normal, and it would spread to every future path assertion rather than staying in the one case that round-trips through `relative()`.
+
+**Re-register the runners so `workFolder` matches the directory casing.** That repairs the underlying inconsistency, but `.runner` also carries the agent identity, pool, and server URLs, so hand-editing it risks a registration mismatch, and the test would remain fragile for any other host whose temp directory and working directory disagree on casing.
+
+**Normalize through `realpath()` in the expectation.** `realpath()` returns the on-disk casing, which is the `cwd` spelling here, so the case would pass; it also resolves symlinks, which changes what the assertion covers on hosts where the temp directory is a link.
+
+## Consequences
+
+The relative-root case now depends on `resolve()` alone rather than on the two spellings agreeing, so it passes on hosts whose temp directory and working directory disagree on casing. The underlying runner registration is untouched: a `workFolder` whose spelling differs from the directory on disk stays that way, so any future assertion that compares a `tmpdir()`-derived absolute path against a `cwd`-derived one will meet the same disagreement.
+
+The changed case passes, and the whole `session-persistence-jsonl` suite passes at 242 cases. The mechanism was reproduced away from Windows with `path.win32`: `relative()` on two differently-cased spellings of one directory returns a prefix-free relative path, `resolve()` rebuilds it from the `cwd` spelling, and the two absolute strings differ; with both sides spelled alike the same code matches. The regression check above — removing `resolve()` from the plugin — turns the case red while the fixture root and the working directory share a drive letter. Across drives `relative()` returns an absolute path, so both spellings already agree and the check cannot go red; the fixture roots come from `tmpdir()`, so the check only goes red where that path and the working directory share a drive.

+# Agent Note: 测试期望值里的大小写不敏感路径往返
+
+Status: implemented

+
+## 问题
+
+[`packages/session/session-persistence-jsonl/tests/jsonl.spec.ts`](../../../../packages/session/session-persistence-jsonl/tests/jsonl.spec.ts) 有一条用例验证「定位 session 之前会先解析相对 `root`」。它传给插件的是 `relative(process.cwd(), absoluteRoot)`，而期望值由 `resolve(absoluteRoot)` 算出——同一个目录、两个不同的起点。
+
+在大小写不敏感的文件系统上，这两个起点的拼写可能不一致。Windows 的 `path.relative()` 按大小写不敏感比较，返回的是去掉公共前缀之后的相对路径，前缀的大小写信息随之丢失；随后 `path.resolve()` 用 `process.cwd()` 重新拼出前缀。当 `tmpdir()` 与 `process.cwd()` 共有的那段前缀在两者中拼写大小写不同时，插件解析出的 root 带的是 `cwd` 那种拼写，而期望值带的是 `tmpdir()` 那种拼写，于是 `toEqual` 比较的是指向同一个文件的两个字符串。
+
+当 `tmpdir()` 与 `process.cwd()` 共享一段路径前缀、但两者对它的拼写不同时，主机就处在这个状态——例如把 `TMP` 以一种拼写映射进 runner 工作树、而 workspace 路径用另一种拼写。仅仅落在同一目录树内并不够：若两者的前缀拼写相同，往返会得到同一个字符串。该用例只在那里失败、别处都通过，看起来像 flake，实际是两种拼写之间一个固定的分歧。
+
+## 决定
+
+期望值改为解析「插件实际收到的那个相对 root」。两侧都经过同一次 `resolve(cwd, relative)`，大小写不敏感的往返就不可能把两种拼写分别放到比较的两边。
+
+这是只改测试的变更。平台把两种拼写视为同一个文件，所以存储行为不依赖 `resolve()` 产出哪种拼写。字符串本身仍可被观察到：hook 载荷以 `transcript_path` 携带它，shell 贡献者以 `DSH_SESSION_JSONL` 导出它，因此比较这些字符串的消费方仍能看出差异。组合 fixture（测试前置数据）如 [`apps/cli/tests/profiles/headless/tests/fixtures/cli.cordis.yml`](../../../../apps/cli/tests/profiles/headless/tests/fixtures/cli.cordis.yml) 就设置了相对的会话 root——但插件会先解析收到的值再使用，因此相对 root 落盘时只有一种拼写而非两种。
+
+该用例仍然在验证它声称的东西：把插件的 `resolve(config.root)` 降级成 `config.root`（即不再解析相对 root）后，用例转红。
+
+关于「用宿主的 `node:path` API 构造路径」这一相邻决策，归属的 note 是[跨平台测试前置数据](2026-07-22-cross-platform-test-fixtures.zh.md)；本 note 讲的是另一个机制——大小写不敏感文件系统上 `relative()`/`resolve()` 的往返。
+
+## 考虑过的替代方案
+
+**按大小写不敏感的方式比较两个路径。** 这能让受影响的 runner 上变绿，但等于把一个真实的配置分歧当成正常状态接受；而且这种写法会扩散到之后每一条路径断言，而不是留在唯一经由 `relative()` 往返的这一条里。
+
+**重新注册 runner，让 `workFolder` 与目录大小写一致。** 这修的是底层的不一致，但 `.runner` 里同时存着 runner 的注册身份、pool 与 server URL，手工编辑有造成注册失配的风险；而且只要有别的宿主机的临时目录与工作目录大小写不一致，这条用例仍然是脆的。
+
+**在期望值里用 `realpath()` 归一化。** `realpath()` 返回磁盘上的真实大小写，在这里就是 `cwd` 那种拼写，用例会通过；但它同时会解析符号链接，在临时目录本身是链接的宿主机上会改变该断言覆盖的内容。
+
+## 后果
+
+相对 root 那条用例现在只依赖 `resolve()` 本身，不再依赖两种拼写是否一致，因此在临时目录与工作目录大小写不一致的宿主机上也能通过。runner 注册本身未被改动：注册拼写与磁盘目录名不一致的状态会保持下去，所以今后任何拿 `tmpdir()` 派生的绝对路径去和 `cwd` 派生路径比较的断言，都会遇到同一个分歧。
+
+改动后的用例通过，`session-persistence-jsonl` 整套 242 条用例通过。机制在非 Windows 环境用 `path.win32` 复现过：对同一目录的两种不同大小写拼写调用 `relative()` 会得到不含前缀的相对路径，`resolve()` 用 `cwd` 那种拼写重建，两个绝对字符串因此不同；把两侧拼写改成一致后，同一段代码即匹配。上面那条回归检查——把插件的 `resolve()` 去掉——在 fixture（测试前置数据）根与工作目录同盘符时会让用例转红。跨盘符时 `relative()` 返回绝对路径，两种拼写本就相同，该检查无法转红；本文件的 fixture 根来自 `tmpdir()`，所以只有该路径与工作目录同盘时该检查才会转红。

+
+[Parallel pre-push gates](2026-07-06-parallel-pre-push-gates.md) owns the bounded gate scheduler in `scripts/run-gates.ts`; this note adds one scheduling option to that scheduler.
+
+## Problem
+
+The gate scheduler in `scripts/run-gates.ts` runs every independent gate in an aggregate to completion and reports `run-gates: N passed, M failed`. A gate failure does not stop the remaining gates; only gates whose `needs` dependency failed are skipped. On an aggregate that is already red, the remaining gates keep consuming runner time and produce evidence that cannot change the verdict. The largest single cost is the instrumented coverage run in the `ci-coverage` aggregate, which has taken about 27 minutes; in `ci-consumers`, the Node compatibility smoke runs independently of the build, so it keeps running after a build failure that already settles the verdict.
+
+GitHub Actions provides no native cross-job cancellation: `fail-fast` applies only inside a matrix, and the `all checks passed` aggregate settles only after every needed job finishes, so it cannot cancel siblings early. The only in-repository lever is the gate scheduler itself.
+
+## Decision
+
+`run-gates.ts` accepts a fail-fast scheduling option. When enabled, the first blocking gate failure (a gate whose `allowFailure` is not true) aborts the aggregate: the shared `AbortSignal` terminates every running gate's process tree, and every not-yet-run gate is recorded as `skipped` with the error `aborted by fail-fast: <label> failed` (or `aborted by fail-fast: host interruption` when the host signal aborted the run). The exit status remains 1, including when a killed child traps the signal and exits zero: such a result carries the abort mark and is recorded `skipped`, never passed. A gate that settled before the abort took effect keeps its real result, so the summary stays truthful about what produced evidence.
+
+Termination covers the whole tree, not just the direct pnpm wrapper: POSIX signals the detached child's process group (`kill(-pid, SIGTERM)`, escalating unconditionally to `SIGKILL` after 5 seconds) and additionally signals every transitive descendant read from the process table, so the detached leaves of a nested run-gates (the `check:node-compat` and `check:ci:lint:contracts-ready` gates inside `ci-consumers`) are killed without relying on the inner scheduler's own escalation. The descendant list is primed at spawn and refreshed every 5 seconds while the child runs, each tick merging the fresh enumeration into the live-filtered cache (the enumeration is asynchronous — a slow WMI/CIM call is bounded by its own 10-second timeout and never blocks the gate's output draining or exit handling; an enumeration still in flight when the gate settles is cancelled rather than left holding stdio handles, and a snapshot that settles after the child exited is still merged, because the child may be gone while a grandchild keeps `close` pending — exactly when the abort needs the list) so a descendant reparented by an exited intermediate stays tracked across ticks; at abort the fresh enumeration is merged into the same list, then re-signalled on the escalation, because the group kill reaps the direct child and reparents its detached descendants, making them unreachable by parent id afterwards; settlement waits until the group and the captured descendants are gone. On the abort path only, a bounded pipe-drain timer force-closes the stdio streams 10 seconds after the abort, so a descendant holding the write ends (uninterruptible I/O included) cannot keep `close` pending to the job timeout; ordinary runs keep waiting rather than report passed over a live leak. Windows runs `taskkill /PID <pid> /T /F` immediately, because a taskkill without `/F` does not terminate console processes, which is what gate commands are; the same process-table enumeration as POSIX supplies a descendant list there, and each captured descendant is also taskkilled, because a `taskkill /T` rooted at a pid that already exited finds nothing. Windows never reparents, so an exited root's descendants keep it as their parent and remain reachable through the table; the same sampler cadence as POSIX keeps the cache crossing a vanished intermediate's table record (the enumeration is bounded by a 10-second PowerShell timeout so a hung WMI/CIM call cannot stall the abort path). Without this, Windows has no signal forwarding and a wrapper-only kill would orphan the script tree on the shared self-hosted pool. Children are detached into their own POSIX process group only when fail-fast is enabled; ordinary runs keep them in the host group so terminal Ctrl+C still reaches them. Host `SIGINT`/`SIGTERM` on a fail-fast run is forwarded to the abort path, so an interrupted or runner-cancelled run drains and kills its gate trees instead of orphaning them.
+
+The option is enabled through `DSH_GATE_FAIL_FAST` (accepted values: `1` or unset; anything else fails loud through the existing `flagEnabled` contract) on every run-gates aggregate job in `ci.yml`: the three blocking Linux jobs (`node-24` static, `node-24-coverage`, `node-24-consumers`), the Node compatibility matrix (`node-compat`), and the two native Windows lanes that drive aggregates (`windows-build`, `windows-coverage`). `scripts/ci-workflow.spec.ts` pins the flag on those jobs and pins its absence on `windows-observational`, so removing it fails the CI gate.
+
+The `windows-observational` lane stays complete: it is `continue-on-error` by design and exists to collect as much Windows-native evidence per run as possible, so the first failure must not truncate the rest. The `windows` Wine lane and `windows-native-tests` run a single script or Vitest command rather than a run-gates aggregate, so the scheduler option does not apply to them. The master serial standby lanes (`serial-linux-selfhosted`, `serial-windows`) and the manual runner benchmarks do not set the flag: they are completeness drills that must execute the full aggregate to prove pool readiness.
+
+## Consequences
+
+A red pull-request run ends sooner. The largest saving is in `ci-coverage`: a failing exempt-heavy gate aborts the multi-minute instrumented coverage gate instead of letting it run out.
+
+The trade-off is diagnostic: one push returns only the first blocking failure instead of the full failure set, so resolving several independent failures may take more push-fix rounds. Killed gates are recorded as `skipped` with the fail-fast error, so the summary line `N passed, M failed, K skipped` remains truthful about what produced evidence and what did not. A gate that ignores `SIGTERM` is force-killed after the 5-second grace. A tree that survives both signals holds the aggregate only while its direct child's stdio stays open; once `close` fires, the group-liveness poll gives up after 8 seconds and the run settles with a loud `gate tree not quiescent` warning instead of reporting a clean tree.
+
+## Alternatives considered
+
+**Cross-job cancellation watchdog.** A job that polls sibling conclusions and calls the run-cancel API would stop all lanes on the first failure. It is not native, adds a polling dependency and token surface, and discards the parallel evidence other jobs have already produced. Rejected; fail-fast at the scheduler is orthogonal to the job topology and carries none of that.
+
+**Consolidating the three Linux jobs into one check.** A single job could fail fast natively, but it would lose the independent runner allocation whose queue-delay overlap is documented in the [independent CI consumer build](2026-07-30-independent-ci-consumer-build.md) note, and it would make the coverage long tail the tail of the whole job. Rejected; fail-fast applies within the existing job split instead.
+
+**Signaling only the direct child.** The first implementation sent `SIGTERM` to the pnpm wrapper and relied on pnpm forwarding it to the script child. A probe confirmed the forwarding on POSIX. Rejected: Windows has no signal forwarding, and a wrapper-only kill orphans the script tree on the shared self-hosted pool; the tree termination above covers both platforms.

+# Agent Note: 门禁运行器快速失败
+
+Status: implemented
+
+[English](2026-08-27-gate-runner-fail-fast.md) | 中文
+
+[并行推送前门禁](2026-07-06-parallel-pre-push-gates.zh.md)拥有 `scripts/run-gates.ts` 中有界的门禁调度器；本笔记为该调度器新增一个调度选项。
+
+## 问题
+
+`scripts/run-gates.ts` 中的门禁调度器会把一个聚合流程里的每个独立门禁都跑完，然后报告 `run-gates: N passed, M failed`。某个门禁失败并不会停止其余门禁；只有 `needs` 依赖失败的门禁会被跳过。当聚合流程已经确定失败时，剩余门禁仍在消耗运行器时间，产出的证据也无法改变结论。最大的单项成本是 `ci-coverage` 聚合流程里的插桩覆盖率运行，实测约 27 分钟；在 `ci-consumers` 中，Node 兼容性冒烟检查与构建相互独立，因此它会在构建失败、结论已定的情况下继续运行。
+
+GitHub Actions 不提供原生的跨作业取消：`fail-fast` 只作用于矩阵内部，而 `all checks passed` 聚合流程要等所有必需作业结束后才落定，因此它无法提前取消兄弟作业。仓库内唯一可用的杠杆就是门禁调度器本身。
+
+## 决策
+
+`run-gates.ts` 接受一个快速失败调度选项。启用后，首个阻塞性门禁失败（`allowFailure` 不为 true 的门禁）即中止整个聚合流程：共享的 `AbortSignal` 终止每个运行中门禁的整个进程树，所有尚未运行的门禁记录为 `skipped`，错误信息为 `aborted by fail-fast: <label> failed`（当宿主信号中止运行时为 `aborted by fail-fast: host interruption`）。退出状态保持为 1——即使被终止的子进程捕获信号并以 0 退出，这类结果也带有中止标记、记为 `skipped`，绝不记为通过。在中止生效前已结算的门禁保留其真实结果，因此汇总行仍如实反映哪些门禁产出了证据。
+
+终止覆盖整棵进程树，而不只是直接的 pnpm 包装进程：POSIX 向分离子进程所在的进程组发信号（`kill(-pid, SIGTERM)`，5 秒后无条件升级为 `SIGKILL`），并额外按进程表逐个信号所有传递性后代——嵌套 run-gates（`ci-consumers` 里的 `check:node-compat` 与 `check:ci:lint:contracts-ready` 门禁）分离出去的叶子进程因此不依赖内层调度器自己的升级也能被杀掉。后代列表在 spawn 时预填、随后在子进程运行期间每 5 秒刷新（枚举是异步的——慢的 WMI/CIM 调用以自身 10 秒超时封顶，绝不会阻塞门禁的输出排空或退出处理；门禁结算时仍在途的枚举会被取消，而不是留着持有 stdio 句柄；子进程退出后才结算的快照仍会被合并，因为子进程可能已消失而孙进程仍持有 `close` 未触发——这正是中止需要该列表的时刻），每个采样 tick 把新枚举结果并入存活过滤后的缓存，被已退出中间进程 reparent 的后代因此跨 tick 仍被跟踪；中止时把新枚举结果并入同一列表，随后在升级时再次信号：组杀会重收直接子进程并 reparent 其分离后代，之后按父 id 不可达，因此结算要等进程组与已捕获后代都消失。仅在中止路径上，有界 pipe-drain 定时器会在中止后 10 秒强制关闭 stdio 流，因此持有写端的后代进程（包括不可中断 I/O）无法让 `close` 一直挂到作业超时；普通运行保持等待，而不是在有存活泄漏时报告通过。Windows 立即运行 `taskkill /PID <pid> /T /F`，因为不带 `/F` 的 taskkill 无法终止控制台进程，而门禁命令正是控制台进程；与 POSIX 相同的进程表枚举在 Windows 上也提供后代列表，每个捕获的后代同样被 taskkill——因为以已退出 pid 为根执行 `taskkill /T` 找不到任何东西，而 Windows 从不 reparent，已退出根的子孙仍以它为父、通过进程表可达；与 POSIX 相同的采样节奏让缓存跨过已消失中间进程的进程表记录（枚举以 10 秒 PowerShell 超时封顶，挂起的 WMI/CIM 调用不会拖住中止路径）。没有这一步，Windows 上不存在信号转发，只杀包装进程会在共享自托管池上留下孤儿脚本树。只有在启用快速失败时，子进程才会分离到自己的 POSIX 进程组；普通运行保持子进程在宿主进程组内，终端 Ctrl+C 仍能送达它们。快速失败运行上的宿主 `SIGINT`/`SIGTERM` 会转发到中止路径，因此被中断或被运行器取消的运行会排干并杀死自己的门禁进程树，而不是留下孤儿。
+
+该选项通过 `DSH_GATE_FAIL_FAST` 开启（可接受值：`1` 或未设置；其它值通过既有的 `flagEnabled` 契约响亮失败），作用于 `ci.yml` 中所有由 run-gates 驱动的聚合作业：三个阻塞性 Linux 作业（`node-24` 静态、`node-24-coverage`、`node-24-consumers`）、Node 兼容性矩阵（`node-compat`）以及两个驱动聚合流程的原生 Windows 车道（`windows-build`、`windows-coverage`）。`scripts/ci-workflow.spec.ts` 固定了这些作业上的该标志，并固定 `windows-observational` 上不存在该标志，移除它会令 CI 门禁失败。
+
+`windows-observational` 车道保持完整执行：它按设计是 `continue-on-error`，存在的意义是每次运行尽量收集 Windows 原生证据，因此首个失败不应截断其余部分。`windows` Wine 车道和 `windows-native-tests` 运行的是单个脚本或 Vitest 命令，不是 run-gates 聚合流程，因此调度选项不适用于它们。master 串行备用车道（`serial-linux-selfhosted`、`serial-windows`）和手动运行器基准测试不设置该标志：它们是完整性演练，必须执行完整聚合流程以证明池的可用性。
+
+## 结果
+
+红色拉取请求运行会更早结束。最大节省在 `ci-coverage`：失败的豁免重型门禁会中止多分钟的插桩覆盖率门禁，而不是让它跑完。
+
+代价在诊断侧：一次推送只返回第一条阻塞性失败，而不是完整失败集，因此解决多个独立失败可能需要更多次推送-修复往返。被终止的门禁记录为带快速失败错误的 `skipped`，因此 `N passed, M failed, K skipped` 汇总行仍然如实反映哪些门禁产出了证据、哪些没有。忽略 `SIGTERM` 的门禁会在 5 秒宽限期后被强制终止。同时扛过两种信号仍存活的进程树，只有在直接子进程的 stdio 保持打开时才会拖住聚合流程；一旦 `close` 触发，进程组存活轮询在 8 秒后放弃，运行以响亮的 `gate tree not quiescent` 警告结算，而不是报告一棵干净的树。
+
+## 备选方案
+
+**跨作业取消看门狗。** 一个轮询兄弟作业结论并调用运行取消 API 的作业可以在首个失败时停止所有车道。它不是原生能力，会增加轮询依赖和令牌暴露面，并丢弃其它作业已并行产出的证据。已拒绝；调度器层面的快速失败与作业拓扑正交，不带来上述任何负担。
+
+**把三个 Linux 作业合并成一个检查。** 单个作业可以原生快速失败，但会失去独立的运行器分配——其排队延迟重叠的收益记录在[独立 CI 消费方构建](2026-07-30-independent-ci-consumer-build.zh.md)笔记中——并且会让覆盖率长尾成为整个作业的尾部。已拒绝；快速失败在既有作业拆分内生效即可。
+
+**只向直接子进程发信号。** 第一版实现向 pnpm 包装进程发送 `SIGTERM`，依赖 pnpm 把它转发给脚本子进程。探针确认了 POSIX 上的转发。已拒绝：Windows 没有信号转发，只杀包装进程会在共享自托管池上留下孤儿脚本树；上述整树终止覆盖两个平台。

 An empty or whitespace-only `$DSH_HOME` is treated as unset; otherwise `resolve('')` would silently place the home at the current working directory. The harness keeps all user data under one root; there is no XDG config/data/cache split. `dshHomePath(...segments)` joins deployment-owned children onto that root, and `dsh-app-boot` exposes it to Loader `!!js` config expressions before mounting entries, so shipped compositions derive `sessions` and `storages` without copying the resolver. `dshHomeDisplay()` names a resolved root symbolically for user-facing paths — `~/.dsh` for the default home, `$DSH_HOME` for any configured home — so the user-global `AGENTS.md` label never leaks an absolute machine path.

 Scope is deliberately narrow: this fixes the REGISTRATION-ORDER race, not plugin behavior. A `system-prompt/assemble` listener may still add, remove, or rearrange tools — same as it may edit sections after their sort — and owns the determinism of what it emits; the waterfall contract already demands deterministic listeners (the reconstructability invariant would catch a listener that diverges between build and replay).

One schemastery footnote is load-bearing: a schemastery array defaults to `[]`, but an omitted `toolOrder` must stay ABSENT (= lexicographic) rather than become an explicitly-configured empty list (invalid — it lacks the rest entry), so every schema on the chain forces the default to `undefined`.

-`agent-spine-demo` accepts an optional `goals` composition object containing the goal-domain and model-tool owner configs. Omission or `false` leaves the stack unmounted. This explicit opt-in is important for headless one-shot callers: their result API settles one correlated physical turn and must not silently become a long-running logical goal operation.
+`dsh-base` mounts the goal domain and model-tool owners as explicit rows, while the standalone `sdk-minimal` tree omits the complete stack. This explicit composition choice is important for SDK one-shot callers: their result API settles one correlated physical turn and must not silently become a long-running logical goal operation.
 
 The TUI app bundle makes the opposite product choice. It defaults `goals` to the owner defaults and mounts the goal domain, model tools, same-session driver, command registry, and this producer; `goals: false` removes the stack coherently. The Web bundle keeps the goal domain and driver on the host for remote access, disables the host command producer, and mounts the producer in the `standard`, `code`, and `cordis` agent presets; `minimal` omits both the command and model goal tools. A preset switch does not mutate host-owned goal state, and the Web GoalBar retains direct edit, pause, resume, and clear controls. The [ACP automation app](../simplification/2026-07-23-acp-automation-only-protocol.md) also defaults the goal domain and model tools but deliberately omits command services. The Python SDK runtime closure ships this producer, commands, and the goal stack so an external `cordis.yml` can compose the same command.

 TUI 应用包作出相反的产品选择。它默认让 `goals` 使用所有者默认值，并挂载目标领域、模型工具、同会话驱动器、命令注册表与本生产方；`goals: false` 会一致地移除整个栈。Web 组合包把 goal 领域与驱动器保留在 host 中以供远程访问，停用 host 命令生产方，并在 `standard`、`code` 与 `cordis` agent preset 中挂载该生产方；`minimal` 会同时省略命令与模型 goal 工具。切换 preset 不会改变 host 所拥有的 goal 状态，Web GoalBar 仍保留直接 edit、pause、resume 与 clear 控制。[ACP（Agent Client Protocol）自动化应用](../simplification/2026-07-23-acp-automation-only-protocol.zh.md)也默认挂载目标领域与模型工具，但有意省略命令服务。Python SDK 运行时闭包交付本生产方、命令与目标栈，使外部 `cordis.yml` 能组合相同命令。

Shipped profile trees do not mount it by default because terminal-multiplexer context is surface-specific; a composition that needs it adds its row explicitly.
 
 **Pull on the first step of each turn, not a tmux push.** The plugin prepends an `agent/pre-step` listener and acts only when `step === 1`. A pull model needs no background process, no hook installation in the user's tmux, and no teardown; it re-reads current state each turn so a moved, renamed, or re-laid-out pane is picked up naturally. Gating on the first step makes the reading per-turn: a location is stable within a turn, and re-querying every step would add cost without new information. A pane moved mid-turn is reflected on the next turn, which is the accepted tradeoff for the simpler design.

 `@deepseek-ai/dsh-tool-str-replace-editor` independently consumes `ctx.fs` and registers `str_replace_editor` with `view`, `create`, `str_replace`, and `insert`. It provides numbered text views, filtered two-level directory listings, unique literal replacement, canonical insertion boundaries, and bounded output. Paths are absolute; file views preserve content tabs so copied text remains valid literal replacement input; mutations preserve tabs outside the requested edit; and the public schema and failures use only `old_str`. Command-specific fields accept `null` placeholders: execution treats them as omitted when the selected command does not use them, preserves required-field checks, treats `view_range: null` as a full view, and rejects `str_replace.new_str: null` so only omission requests deletion. The plugin can compose with persistent Bash, one-shot Bash, sandboxed Bash, or no shell.
 
-`dsh-system-prompt` accepts `includeHarnessIdentity: false`, while `dsh-agent-spine-demo` forwards that setting and accepts `toolBash: false`. A deployment can therefore own an exact persona and replace the spine's native Bash without duplicate prompt or tool registrations. Existing defaults remain unchanged.
+`dsh-system-prompt` accepts `includeHarnessIdentity: false`, and profile compositions own that row together with their selected shell-tool rows. `sdk-minimal` sets the value to `false` and mounts only its platform-selected persistent shell, so a deployment can own an exact persona without duplicate prompt or tool registrations. Existing defaults remain unchanged.
 
 Both plugins are included in the Python runtime closure. The persistent Bash closure also includes the PTY service/local backend and the sandbox services required by that backend. Because `node-pty` executes a native `spawn-helper` on macOS, each packaged macOS runtime executable ships with a `-spawn-helper` sibling; Linux uses `forkpty` directly. A pinned `node-pty` patch checks `DSH_NODE_PTY_SPAWN_HELPER` first, so it remains a true override for a current external consumer that supplies a non-sibling helper. When the override is unset, the patch resolves the packaged executable sibling if present and otherwise preserves upstream lookup in ordinary Node runs. The macOS builders fail before publication when the helper is absent or not executable.

 One-shot `session/request_permission` remains. It is a machine policy channel for bridge-owned agents, not a human approval UI: the answerer accepts only an exact agent object in the bridge's live session map, delegates foreign or call-less requests, and maps failed RPCs to the fail-closed unavailable outcome. The client chooses allow once, reject once, or cancel, and the bridge never turns that response into a durable grant.

+# Agent Note: Remove the agent-spine demo package
+
+Status: implemented

+English | [中文](2026-08-26-remove-agent-spine-demo.zh.md)
+
+## Problem
+
+`@deepseek-ai/dsh-agent-spine-demo` was named and located as an example but exposed a public composition plugin with a large merged configuration. Its only shipped consumer was `dsh-sdk-minimal`, where one plugin row hid the mandatory agent runtime from a bundle whose purpose is a complete explicit tree. Every other consumer was a test. The package also duplicated composition policy already owned by `dsh-base` without providing a capability that could evolve independently.
+
+## Decision
+
+The package, its public configuration, and the `packages/examples` group are deleted without an alias. `dsh-sdk-minimal` now declares timer, LLM, session, title, system-prompt, tools, agent, retry, local jobs, invariant registry and companions, and agent-loop rows directly in its patch. It still omits workspace instructions, skills, model-facing job tools, goals, subagents, settings, and the other `dsh-base` features.
+
+Profile integration tests load the shipped profile and bundle patches through `loadProfile`, then pass the production patches and narrow test `*.patch.yml` files to the same root `cordis:include` used by application boot. Test patches cover a mock provider or model, isolated persistence, and the plugin under test without recreating the mandatory agent tree. SDK server unit tests that do not exercise profile integration mount `dsh-agent-loop-testkit` and `dsh-agent-loop` locally.
+
+## Verification
+
+The `sdk-minimal` bundle test checks its exact row inventory and owner configurations, and the built CLI test checks the emitted profile tree. Real-Loader fixtures exercise the shipped bundle layers with test overlays, while SDK server tests exercise the package-local testkit composition. Configuration, package, invariant, generated-document, build, hygiene, and snapshot gates verify that no live product or test imports the deleted package.
+
+## Alternatives considered
+
+**Replace the package with `dsh-base`.** Rejected because `dsh-base` is the full product foundation, while `sdk-minimal` deliberately omits its settings, credentials, workspace context, skill, goal, compaction, telemetry, subagent, and broad tool rows. Replacing the package with base would change the profile instead of removing indirection.
+
+**Rename and move the public composition package.** Rejected because no two shipped products share that composition. A renamed package would preserve the merged configuration forwarding and hide the row owners from profile patches.
+
+**Keep a private mandatory-runtime composition for tests.** Rejected because a private TypeScript tree still duplicates production composition policy and can drift from the shipped profile. Test overlays remain explicit without owning the rows they do not change.
+
+## Consequences
+
+The pre-release package import and its merged configuration are removed. `sdk-minimal` becomes longer but every mounted feature is individually visible and patchable. `dsh-base` remains the full product composition and cannot substitute for the smaller tree. Profile integration tests now change when the shipped base or mode bundle changes, so their Loader and recorded-session coverage reflects the production tree instead of a parallel test composition.

+# Agent Note: 删除 agent-spine demo 包
+
+Status: implemented
+
+[English](2026-08-26-remove-agent-spine-demo.md) | 中文
+
+## 问题
+
+`@deepseek-ai/dsh-agent-spine-demo` 的名称与位置将它描述为示例，但它实际暴露了带大型合并配置的公开组合插件。其唯一交付消费方是 `dsh-sdk-minimal`，其中一个插件配置行隐藏了必需的 agent（智能体）运行时，而该组合包的目的本是提供完整、显式的配置树。其他消费方全部是测试。该包还重复了已归 `dsh-base` 所有的组合策略，却没有提供可独立演进的能力。
+
+## 决策
+
+删除该包、其公开配置与 `packages/examples` 分组，不保留别名。`dsh-sdk-minimal` 现在直接在 patch 中声明 timer、LLM（大语言模型）、会话、标题、系统提示词、工具、agent、重试、本地后台任务、不变量注册表与配套入口，以及 agent loop（智能体循环）配置行。它仍然省略工作区指令、skill（技能）、面向模型的后台任务工具、goal、subagent、settings 与 `dsh-base` 的其他功能。
+
+Profile 集成测试通过 `loadProfile` 加载已交付 profile 与组合包 patch，再把生产 patch 和窄测试 `*.patch.yml` 文件交给应用启动使用的同一个根 `cordis:include`。测试 patch 覆盖模拟提供方或模型、隔离持久化和被测插件，不会重新创建必需 agent 配置树。不覆盖 profile 集成的 SDK server 单元测试在本地挂载 `dsh-agent-loop-testkit` 与 `dsh-agent-loop`。
+
+## 验证
+
+`sdk-minimal` 组合包测试检查其精确配置行清单与所有方配置，构建后的 CLI 测试检查输出的 profile 配置树。真实 Loader fixture 以测试 overlay 覆盖已交付组合包层，SDK server 测试则覆盖包内 testkit 组合。配置、包、不变量、生成文档、构建、hygiene 与快照门禁验证没有现行产品或测试导入已删除包。
+
+## 考虑过的替代方案
+
+**用 `dsh-base` 替换该包。** 拒绝，因为 `dsh-base` 是完整产品基础，而 `sdk-minimal` 刻意省略其 settings、凭据、工作区上下文、skill、goal、压缩、遥测、subagent 与广泛工具配置行。用 base 替换会改变 profile，而不是移除间接层。
+
+**重命名并移动公开组合包。** 拒绝，因为没有两个交付产品共享该组合。重命名后的包仍会保留合并配置转发，并在 profile patch 中隐藏配置行所有方。
+
+**为测试保留私有的必需运行时组合。** 拒绝，因为私有 TypeScript 配置树仍然会重复生产组合策略，并可能偏离已交付 profile。测试 overlay 可以保持显式，同时不拥有其未修改的配置行。
+
+## 后果
+
+预发布包导入与合并配置被删除。`sdk-minimal` 变得更长，但每个挂载功能都单独可见、可 patch。`dsh-base` 仍是完整产品组合，不能替代更小的配置树。已交付 base 或模式组合包发生变化时，profile 集成测试现在也会随之变化，因此其 Loader 与 recorded-session 覆盖反映生产配置树，而非平行的测试组合。

 本文介绍 DeepSeek Harness 整体架构，它是 **DeepSeek Code** 的底层基座。微内核设计讨论中确立了核心设计准则：**一切皆插件**。内核刻意做得极精简，仅包含少量抽象服务，外加一个实体循环插件 `dsh-agent-loop`。所有产品功能均基于本文定义的扩展接口开发为独立插件，无需改动主循环逻辑。
 
-> Dependency rule: extension plugins depend on interfaces, never on `dsh-agent-loop` (the loop is swappable); the sanctioned exception is the composition bundle `dsh-agent-spine-demo`, whose job is assembling the concrete spine.
+> Dependency rule: extension plugins depend on interfaces, never on `dsh-agent-loop` (the loop is swappable); composition bundles such as `dsh-base` and `dsh-sdk-minimal` may assemble the concrete loop.
 
-依赖约束规范：各类扩展插件仅依赖抽象接口，严禁直接依赖 `dsh-agent-loop`（该主循环支持替换实现）；唯一允许的特例是组合包 `dsh-agent-spine-demo`，它的职责是组装整套实体主干。

 ## Summary
 
-The context group provides plugins that add model-visible context to each request without defining any tool: workspace instruction files become guidance, `@file` mentions offer path completion, other sessions can be referenced as bounded snapshots, and the model can see the current time and the agent's tmux location. All of them are opt-in except `agent-instructions`, which ships enabled in the default `dsh-agent-spine-demo` bundle and can be disabled through bundle config. Context is durable: injected instructions and references enter session history as user-role messages, so they persist, replay, and compact like other conversation content. This page maps the group; each package README owns the per-package contract.

 ## Summary
 
-`dsh-agent-instructions` loads `AGENTS.md`-compatible workspace instruction files into model context: the user-global file and the project chain reach the first request as one durable baseline, and successful `read`, `write`, or `edit` calls bring newly relevant nested files, changes, and removals into later requests. It ships enabled in the default `dsh-agent-spine-demo` bundle and can be disabled through bundle config. Everything is bounded by a byte budget: broader files are omitted before the most specific file is truncated, and an empty chain contributes nothing. There is no file watcher — external edits become visible on the next successful filesystem touch or when a resumed session reconciles its baseline.

-`dsh-agent-instructions` 将兼容 `AGENTS.md` 的工作区指令文件加载到模型上下文：用户全局文件与项目指令链作为一条持久基线进入第一次请求，成功的 `read`、`write` 或 `edit` 调用会把新出现的嵌套文件、变更与移除带入后续请求。它随默认 `dsh-agent-spine-demo` 组合包发布并默认启用，可通过组合包配置禁用。一切内容都受字节预算约束：较宽泛的文件先被省略，最具体的文件最后被截断，空指令链不产生任何内容。没有文件 watcher——外部编辑会在下一次成功的文件系统 touch 时，或恢复后的会话对账其基线时变得可见。

 ## Summary
 
-The core group provides the product API spine of the DeepSeek Harness: an append-only session log, system-prompt assembly, a tool registry, the `Agent` handle, and the concrete loop that drives them. Every composition boots these packages, and plugins and consumers build against their stable contracts. A turn flows through all of them — the loop claims a prompt, opens a turn on the session log, assembles the request through system-prompt, streams the model response, dispatches tool calls through the registry, and appends every model-visible fact back to the log. Choose this group when you build an agent or extend one; the runnable default composition is [`examples/agent-spine-demo`](../examples/agent-spine-demo/README.md).

-## Summary
-
-The examples group provides the reusable agent spine for tests and custom deployments that need a concrete composition without assembling it by hand. Its `-demo` npm suffix marks it as support infrastructure rather than a product interface. ACP, SDK, and one-shot applications launch through the `acp`, `sdk` or `sdk-minimal`, and `headless` profiles. This group contains no application entrypoint.

-`dsh-agent-spine-demo` gives you a working agent in one plugin: mount it, add an LLM adapter and an executor, and you can run a full agent conversation — in-memory sessions with automatic titles, a system prompt with your persona and workspace instructions, tools for bash, skills, and background jobs, and a loop that runs turns with retries. You configure it in user terms: persona, tool order, workspace-context budget, which agents to pre-create, optional persisted goals, and background-job limits. It ships no UI, executor, or persistence backend, and it adds no prompts or tool schemas of its own — the model sees only what your configuration produces. Use it when you are building a headless, ACP, or JSON-RPC agent and want the common agent machinery without building it yourself. Read this package for what you get out of the box and what you must supply.

-## Use this package
-
-Use this bundle when you are building an agent without a UI and want the common machinery handled for you: sessions, prompts, tools, and the turn loop. The common path is explicit — mount the bundle with a workspace-context budget, add an LLM adapter and a bash executor as sibling plugins, and provide `agents` when your entry point pre-creates them. When everything is configured, your agent accepts a prompt and returns a completed answer while the process keeps its session in memory.
-
-### What the bundle includes
-
-Out of the box you get: in-memory sessions with automatic fallback titles; a system prompt assembled from your persona, the Harness identity, and optional workspace instructions; model-facing tools for bash, local skills, and background jobs; optional persisted goals the agent can create and track; and a loop that runs turns with provider-routed retries. Add a session-persistence provider when sessions must survive process exit. The full plugin list lives in the implementation section below.
-
-### What stays outside the bundle
-
-These pieces are yours to supply; the bundle leaves them out so each entry point can pick its own:
-
-- **The LLM adapter** — you add the provider that calls a model; pick `llm-deepseek`, `llm-pi-ai`, or `llm-replay`.
-- **Model-backed session-title providers** — you get deterministic fallback titles out of the box; add at most one model-based titling provider if you want smarter titles.
-- **The bash executor** — the bundle provides the bash tool; you add the executor that runs commands (`bash-local` or a sandboxed implementation).
-- **Non-local skill providers** — local skills load out of the box; add providers for embedded or remote catalogs if you need them.
-- **The entry point and per-app infrastructure** — headless, ACP, and JSON-RPC apps own transport and output choices; you pick the one that fits your deployment.
-
-### Minimal configuration
-
-The smallest working setup mounts the bundle with a workspace-context budget, plus an LLM adapter and an executor:
-
-```yaml
-- name: '@deepseek-ai/dsh-agent-spine-demo'
-  config:
-    workspaceContext:
-      maxBytes: 4096
-- name: '@deepseek-ai/dsh-llm-deepseek'   # concrete adapter for ctx.llm
-- name: '@deepseek-ai/dsh-bash-local'     # executor for ctx.shell
-```
-
-`workspaceContext` is the one required field: give it a byte budget so workspace files load into the agent's context, or set `false` for hermetic prompts. `agents` defaults to none, so pass the agents you want running — or omit it when your entry point creates them on demand (the ACP app does this). You know the setup works when the agent answers a first prompt and its session is saved.
-
-| Field | Default | What it configures |
-|---|---|---|
-| `agents` | `[]` | which agents your entry point pre-creates; omit to create them on demand |
-| `maxParallelToolCalls` | agent-loop default | how many tool calls may run at once; `1` is serial |
-| `includeHarnessIdentity` | `true` | whether the system prompt names the DeepSeek Harness identity |
-| `includeRuntimeContext` | `true` | whether the agent's history includes dynamic runtime-context snapshots |
-| `persona` | `''` | the deployment persona text in the system prompt |
-| `toolOrder` | lexicographic | the order the model sees tools in |
-| `tools` | `{ mode: 'native' }` | how tools reach the model: native schemas, PTC mode, or both |
-| `dshHome` | `$DSH_HOME` or `~/.dsh` | the harness home used for the bash environment and local skill folders |
-| `sessionTitle` | example limits | fallback title limits: 5 words, 40 fallback bytes, 80 accepted bytes |
-| `workspaceContext` | required | byte budget for loading workspace files into context, or `false` |
-| `skills` | enabled | whether local skills load and the skill tool is available |
-| `toolBash` | mounted | the bash tool; set `false` when another plugin owns `bash` |
-| `jobs` | owner default | how many background jobs each owner may run at once |
-| `toolJobs` | mounted | the background-job control tools; `false` keeps jobs without the tools |
-| `invariants` | owner default | developer setting: which package checks run and which packages are filtered |
-| `goals` | unmounted | optional persisted goals the agent can create and track across turns |
-
-The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-agent-spine-demo) is the exhaustive source for every accepted field and its source declaration.
-
-### Request retry and billing
-
-Provider requests are retried automatically: if a call fails, the agent tries again in a new numbered step. Retries can cost you — each attempt may be billed, and `always` mode retries without limit — so usage accounting stays at your entry point. The retry itself does not clutter the conversation; you see the successful result.

-<details>
-<summary>Implementation internals — click to expand</summary>
-
-This section explains how the bundle composes the spine and points at the code that realizes it; the observable behavior is fully covered in [Use this package](#use-this-package).
-
-### Composition model
-
-`apply(ctx, config)` mounts each child plugin under the bundle fiber and forwards every config field to the child that owns it. Cordis pends each fiber on its `inject` declarations until the services it needs exist, so load order is irrelevant to correctness; the listing below mirrors dependency layering for readability. `pickSpineConfig()` copies only the bundle-owned fields from an app config, so entry-point settings never leak into the spine; conflicting `dshHome` values fail during composition because local skills and the managed bash environment must share one harness home. The retry policy keeps retry status, provider errors, and failed partial chunks outside model history, and it reconstructs a retried request with its prior prefix intact so provider caches stay reusable.
-

-
-### Why a code bundle, not a shared YAML include
-
-A YAML include can deduplicate config but cannot own a bin or provide entry-point defaults; the ACP app package makes protocol-pure stdout wiring the default, though a leaf can still add an unsafe logger. Bundle children register services in the root isolate-keyed store, so injected leaf siblings see them without load-order coupling.
-
-### Invariant companions
-
-The bundle mounts the invariant registry and its four package companions (`session`, `agent`, `scope`, `agent-loop`). `invariants.enabled: false` or package filters suppress the checks but do not remove the service or companion registrations; Session's always-on validation and freezing are separate. The package's own companion ([`src/invariant.ts`](src/invariant.ts)) installs no runtime invariant because this composition package owns no independent event stream or mutable data.
-
-### Source map
-
-| File | Role |
-|---|---|
-| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, `pickSpineConfig()`, `apply()` mounting every child |
-| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; composition wiring is covered by tests) |

-
-<a id="model-experience"></a>
-## Model Experience
-
-Indirectly, through the model-facing child plugins the bundle mounts — `dsh-system-prompt`, `dsh-tools`, `dsh-tool-skill`, `dsh-tool-bash`, `dsh-tool-jobs`, and `dsh-llm-retry`, plus `dsh-tool-goal` and the goal-round driver's prompts when `goals` is enabled; the bundle adds no model-bound wrapper content of its own.
-
-#### KV Cache effect
-
-The bundle adds no request-prefix content of its own; provider cache reuse depends on the mounted consumers' contributions, and `dsh-llm-retry` reconstructs a retried request with its prior prefix intact.
-
-## Known Limitations and Deferred Work
-
-<a id="known-limitations-and-deferred-work"></a>
-
-
-These limits define when the bundle is a poor fit or needs special operational care. They are current package constraints, not a comparison with other composition approaches or a task backlog.
-
-- **Most of the spine set is fixed in code** — `apply()` always mounts the core services; config can omit bundled goals, skills, bash, and task-control tools, but swapping the loop or dropping another spine member means composing a different bundle.
-- **The invariant service and companions remain fixed members** — `invariants.enabled: false` or package filters suppress checks but do not remove the service or companion registrations; Session's always-on validation and freezing are separate.
-- **Retry can duplicate provider billing** — each provider attempt may incur billing, and `always` mode has no attempt limit; usage accounting stays with the entry point.

-<summary>Working context for maintainers — click to expand</summary>
-
-This Dev Note is working context for maintainers; it is explicitly non-authoritative — shipped behavior, limits, and accepted rationale live in the sections above and the package code.
-
-The fallback title limits (5 words, 40 fallback bytes, 80 accepted-title bytes) are an overridable example policy owned by this bundle rather than by `dsh-session-title`; an entry point that needs different bounds passes its own `sessionTitle` config. The `workspaceContext` field is required (not defaulted) because it changes model-visible input; keep that requirement if the field is ever re-shaped.

-## 概述
-
-`dsh-agent-spine-demo` 用一个插件给你一个可工作的 agent（智能体）：挂载它、添加 LLM（大语言模型）适配器与执行器，即可运行完整的 agent 对话——带自动标题的内存会话、包含你的 persona 与工作区指令的系统提示词、bash、skill 与后台任务工具，以及带自动重试的运行轮次循环。你可以用用户术语配置它：persona、工具顺序、工作区上下文预算、预创建哪些 agent、可选持久目标与后台任务上限。它不附带 UI、执行器或持久化后端，且不添加任何自己的提示词或工具 schema——模型只看到你的配置产生的内容。当你构建无头、ACP（Agent Client Protocol）或 JSON-RPC agent、希望复用通用 agent 机制而不必自己搭建时使用它。阅读本包可了解开箱即得的内容，以及需要你自行提供的内容。

-## 使用本包
-
-当你在构建不带 UI 的 agent、希望会话、提示词、工具与轮次循环这些通用机制由本包代劳时使用此组合包。常用路径是显式的——用工作区上下文预算挂载组合包，把 LLM 适配器与 bash 执行器作为同级插件添加，并在入口预创建 agent 时提供 `agents`。配置完成后，你的 agent 就能接受提示词并返回完成的答案，当前进程会把该会话保留在内存中。
-
-### 组合包包含的内容
-
-开箱即得：带自动后备标题的内存会话；由你的 persona、Harness 身份与可选工作区指令组装的系统提示词；bash、本地 skill 与后台任务等面向模型的工具；agent 可以创建与跟踪的可选持久目标；以及带提供方路由重试、运行轮次的循环。会话需要在进程退出后继续存在时，请添加会话持久化提供方。完整插件清单见下方实现章节。
-
-### 留在组合包外的内容
-
-以下部分需要你自行提供；组合包把它们留在外部，让每个入口都能自行选择：
-
-- **LLM 适配器**——你需要添加调用模型的提供方；可选择 `llm-deepseek`、`llm-pi-ai` 或 `llm-replay`。
-- **基于模型的会话标题提供方**——开箱即用确定性后备标题；若想要更智能的标题，可以恰好添加一个基于模型的标题提供方。
-- **bash 执行器**——组合包提供 bash 工具；你需要添加实际运行命令的执行器（`bash-local` 或沙箱化实现）。
-- **非本地 skill 提供方**——本地 skill 开箱即用；需要嵌入式或远程目录时，可以添加相应提供方。
-- **入口与各应用基础设施**——无头、ACP 与 JSON-RPC 应用负责传输与输出选择；请选择适合你部署的那一个。
-
-### 最小配置
-
-最小可用配置是：用工作区上下文预算挂载组合包，再加上 LLM 适配器与执行器：
-
-```yaml
-- name: '@deepseek-ai/dsh-agent-spine-demo'
-  config:
-    workspaceContext:
-      maxBytes: 4096
-- name: '@deepseek-ai/dsh-llm-deepseek'   # concrete adapter for ctx.llm
-- name: '@deepseek-ai/dsh-bash-local'     # executor for ctx.shell
-```
-
-`workspaceContext` 是唯一必填字段：给它一个字节预算，工作区文件就会加载进 agent 上下文；设 `false` 则得到隔离提示词。`agents` 默认为空，因此请传入你想运行的 agent——或者当你的入口按需创建 agent 时省略它（ACP 应用就是这样）。当 agent 回答第一个提示词且会话被保存时，说明配置成功。
-
-| 字段 | 默认值 | 配置内容 |
-|---|---|---|
-| `agents` | `[]` | 你的入口预创建的 agent；按需创建时省略 |
-| `maxParallelToolCalls` | agent loop 默认值 | 同时运行的工具调用数；`1` 表示串行 |
-| `includeHarnessIdentity` | `true` | 系统提示词是否点名 DeepSeek Harness 身份 |
-| `includeRuntimeContext` | `true` | agent 历史是否包含动态运行时上下文快照 |
-| `persona` | `''` | 系统提示词中的部署 persona 文本 |
-| `toolOrder` | 字典序 | 模型看到工具的顺序 |
-| `tools` | `{ mode: 'native' }` | 工具如何到达模型：native schema、PTC mode 或两者 |
-| `dshHome` | `$DSH_HOME` 或 `~/.dsh` | bash 环境与本地 skill 目录使用的 harness 主目录 |
-| `sessionTitle` | 示例限制 | 后备标题限制：5 个词、40 个后备字节、80 个可接受字节 |
-| `workspaceContext` | 必填 | 加载工作区文件进上下文的字节预算，或 `false` |
-| `skills` | 启用 | 是否加载本地 skill 并提供 skill 工具 |
-| `toolBash` | 挂载 | bash 工具；当其他插件拥有 `bash` 时设 `false` |
-| `jobs` | 拥有者默认值 | 每个 owner 可同时运行的后台任务数 |
-| `toolJobs` | 挂载 | 后台任务控制工具；`false` 保留任务但不提供工具 |
-| `invariants` | 拥有者默认值 | 开发者设置：运行哪些包检查、过滤哪些包 |
-| `goals` | 不挂载 | agent 可创建并跨轮次跟踪的可选持久目标 |
-
-生成的[配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-agent-spine-demo)是每个受支持字段及其源声明的穷尽式真源。
-
-### 请求重试与计费
-
-提供方请求会自动重试：调用失败时，agent 会在新的编号步骤中重试。重试可能产生费用——每次尝试都可能计费，`always` 模式没有尝试次数上限——因此用量核算留在你的入口。重试本身不会弄乱对话；你看到的是成功的结果。

-
-本节解释组合包如何组装主干，并指出实现它的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
-
-### 组合模型
-
-`apply(ctx, config)` 把每个子插件挂载到组合包 fiber 下，并把每个配置字段转发给拥有它的子插件。Cordis 会按 `inject` 声明挂起每个 fiber，直到其所需服务存在为止，因此加载顺序不影响正确性；下方的清单只是按依赖分层排列，便于阅读。`pickSpineConfig()` 只从应用配置中复制组合包拥有的字段，因此入口设置绝不会泄漏进主干；`dshHome` 值冲突会在组合时失败，因为本地 skill 与受管 bash 环境必须共享同一个 harness 主目录。重试策略让重试状态、提供方错误与失败的部分分片不进入模型历史，并重建保留先前前缀的重试请求，使提供方缓存保持可复用。

-
-### 为何用代码组合包，而非共享 YAML include
-
-YAML include 可以去重配置，却无法拥有 bin 或提供入口默认值；ACP 应用包默认接出协议纯净的 stdout 接线，但叶节点仍可添加不安全的 logger。组合包子节点把服务注册到根 isolate-keyed store，因此叶节点的同级插件无需依赖加载顺序即可通过注入看到它们。
-
-### 不变式配套插件
-
-组合包挂载不变式注册表及其四个包配套插件（`session`、`agent`、`scope`、`agent-loop`）。`invariants.enabled: false` 或包筛选器会抑制检查，但不会移除服务或配套插件注册；Session 始终启用的校验与冻结是另一套机制。本包自己的配套插件（[`src/invariant.ts`](src/invariant.ts)）不安装任何运行时不变式，因为这个组合包不拥有独立事件流或可变数据。

-<a id="model-experience"></a>
-## 模型体验
-
-模型体验由组合包挂载的面向模型子插件间接提供——`dsh-system-prompt`、`dsh-tools`、`dsh-tool-skill`、`dsh-tool-bash`、`dsh-tool-jobs` 与 `dsh-llm-retry`，启用 `goals` 时还包括 `dsh-tool-goal` 与目标轮次驱动器的提示词；组合包自身不添加任何面向模型的包装内容。
-
-#### KV Cache 影响
-
-组合包自身不添加请求前缀内容；提供方缓存复用取决于所挂载消费方的贡献，`dsh-llm-retry` 重建重试请求时会保留其先前前缀。
-
-## 已知限制与延期工作
-
-<a id="known-limitations-and-deferred-work"></a>
-
-
-这些限制说明组合包何时不合适，或何时需要特别的运维注意。它们是当前包约束，不是与其他组合方式的对比，也不是任务积压。
-
-- **大部分主干集合固定在代码中**：`apply()` 始终挂载核心服务；配置可以省略组合包内的目标、skill、bash 与任务控制工具，但要替换循环或删除其他主干成员，就必须组合另一个组合包。
-- **不变式服务与配套插件仍是固定成员**：`invariants.enabled: false` 或包筛选器会抑制检查，但不会移除服务或配套插件注册；Session 始终启用的校验与冻结是另一套机制。
-- **重试可能重复产生提供方计费**：每次提供方尝试都可能产生计费，`always` 模式没有尝试次数上限；用量核算由入口负责。

-
-后备标题限制（5 个词、40 个后备字节、80 个可接受标题字节）是本组合包拥有、可覆盖的示例策略，而非 `dsh-session-title` 所有；需要不同上限的入口应传入自己的 `sessionTitle` 配置。`workspaceContext` 字段为必填（不设默认值），因为它改变模型可见输入；若该字段日后改型，请保留这一要求。

 ### When to use it
 
-Use the registry for compositions that want live diagnostics. The standard agent composition in [`agent-spine-demo`](../../../packages/examples/agent-spine-demo/README.md) already mounts it with the four core stateful companions — `dsh-session`, `dsh-agent`, `dsh-scope`, and `dsh-agent-loop`. Custom compositions mount the registry and add companions for any other loaded package whose contracts they want checked. Loading the registry alone installs no checks: it ships no product checks of its own, so a composition that never mounts a companion observes no diagnostic behavior.

+### Testing a shipped profile
+
+Profile integration drivers use the repository-only `tests/fixtures/production-profile.ts` helper. It loads the named shipped profile and its bundle patches through `loadProfile`, reconciles the profile's module fallback, and passes the bundle patches followed by the test's `*.patch.yml` files to the root `cordis:include` mounted by `boot`. Those patches should contain only the test provider or model, isolated persistence paths, and subject-specific changes. Package-level unit tests that need an agent loop without profile integration mount `dsh-agent-loop-testkit` locally instead.
+
 ### Driving a fixture turn
 
 `runFixtureTurn(ctx, options)` drives one task through exactly one configured root agent: it waits for the task to reach the durable inbox, forwards canonical events to your observer, flushes the session, and returns the final assistant text plus accumulated usage. Example-local drivers keep configuration, rendering, and assertion ownership.

Subject: [PATCH 09/16] fix(ci): windows coverage runs zero-build like the
 linux lane

The windows-coverage job built the workspace before running the same
ci-coverage gates as Linux, but the instrumented corpus resolves
workspace imports to src through the tsconfig paths map and never
consumes lib/; the two lib-consuming suites (webworker-packer
image-loadable, session-persistence-sqlite built-package) self-skip on
unbuilt checkouts, exactly how the Linux lane already runs them. Remove
the build step so both lanes behave identically, and pin the zero-build
invariant in ci-workflow.spec.ts (red before this change, green after).

Agent Notes updated in place: corrected the build-wait rationale and the
wrong attribution of the packer assertions to the instrumented suite.

 `windows-build` and `windows-native-tests` are dependencies of `all checks passed`; their workspace-build and targeted native-process results are blocking. `windows-coverage` remains an ordinary job but is absent from aggregate `needs`, so its 100%-per-file result stays red and visible without delaying the required verdict. `windows-observational` is also absent from aggregate `needs` and uses `continue-on-error` because Linux owns the blocking static, documentation, package, and built-artifact verdicts.
 
-`windows-coverage` completes a workspace build before [in-job partitioned coverage](2026-08-18-in-job-partitioned-coverage.md) starts four single-worker instrumented shards beside a two-worker exempt-heavy gate. Both coverage gates set Vitest's default per-test and polling budgets to 30 seconds. `windows-observational` owns its own workspace build and production-site validation, starts the independent static gates together, and caps `publint` at eight workers. Its built-bin smoke starts only after every other observational gate settles; the smoke's `needs` edge still requires a successful build, while its `after` edges preserve the diagnostic after another gate fails. This keeps bounded real-application startup measurements from competing with tool-catalog, NodeNext, package, and documentation processes. The SQLite busy-journal pacing fixture injects two busy results followed by success under the normal busy budget and observes each inter-attempt delay, keeping schema-setup scheduling outside its timing assertion. The script-only translation-pairing merge suite runs in the exempt-heavy gate because it imports only `scripts/` sources and child processes; V8 instrumentation contributes no threshold coverage there but magnifies Git-process latency. Lefthook concurrency fixtures retain their outcomes with 30-second case budgets and a 10-second process-ready probe, while the installer allows five seconds for a preempted lock owner to publish its record after exclusive creation. Directory-picker composition gives its debounced config write an explicit 15-second poll budget; workspace-context composition fixtures use a test-owned signal without an unrelated one-second deadline. The LSP sources and the ACL-sandbox sources remain in the Windows denominator: stub-based failure-path suites carry every in-process ACL-sandbox file to 100%, and only the runner entry stays excluded — it executes exclusively as a spawned child outside the instrumented run, its behavior pinned end-to-end by the runner suite.

-The 16-core allocation is the measured capacity point for this inventory. Six-worker coverage trials produced complete passes in 6 minutes 27 seconds and 7 minutes 50 seconds, while exact-head trials with four, three, and two concurrent workers inside one instrumented Vitest process exposed unreliable fixtures and worker exits. Separate single-worker child processes retain process isolation. Historical sixteen-shard samples reduced instrumented coverage to 112.66–122.01 seconds. The pull-request coverage job schedules four instrumented children plus two exempt workers after the build, while the self-hosted complete reference runs its unsharded coverage gates serially with one worker. A six-partition pull-request profile creates enough process and type-aware lint contention to violate bounded test deadlines. Sixteen instrumented shards plus two exempt workers would exceed a 16-core allocation before system overhead. A 32-core comparison reduced aggregate gate time by only 1.47 seconds and still triggered the CJS-lexer fatal inside a fork worker, so additional cores did not provide a reliable wall-clock improvement.

 The first native run exposed two failures hidden by the compatibility lane. Documentation projection tests derived an image basename by splitting only on `/`; they now use Node's platform basename. Chokidar consumers received `%TEMP%` through the `C:\\Users\\RUNNER~1` 8.3 alias while libuv returned the long directory name, tripping its Windows event-path assertion. Shared settings and credentials watchers, plus Cordis module and exact-config HMR, now canonicalize the existing native watch base or deepest existing ancestor before opening the watcher and preserve a missing suffix, while file access and diagnostics retain the configured path.

The native jobs duplicate setup across the build, coverage, and observational workspaces and repeat builds in the build and observational ones, but they lower each job's process count and expose path, watcher, lifecycle, and fixture defects hidden by the compatibility lane.
 
 Maintainers must preserve two intentional execution topologies: the Wine snapshot uses Linux installation plus a hoisted layout to reach win32 binaries, while the native jobs use separate immutable workspaces on the organization-owned 16-core Windows runner. A failure unique to either topology must be classified against that boundary rather than weakened or silently skipped.

Local coverage stays simple unless a caller explicitly chooses the partitioned package script and supplies a valid count greater than one.
 
 Future tuning starts from completed runs at one fixed configuration. Slow progress alone never raises partition count or outer concurrency, because repeated restarts would erase the only evidence needed to choose a stable setting.

Subject: [PATCH 10/16] fix(ci): harden the zero-build coverage assertion and
 list all skip suites

Strengthen the ci-workflow.spec.ts guard to match any 'pnpm run build'
spelling (corepack prefix, multi-line run blocks) instead of one exact
string, and complete the lib-consuming self-skip inventory with the
webworker-runtime transform-corpus import sweep alongside the packer
image assertions and the built-package check. Update the ci.yml comment
and the partitioned-coverage note (both languages) to match, and drop the
stale 'post-build' phase wording and the native-Windows build-wait
rationale from the coverage-exempt comment.

 zero-build coverage

Both coverage lanes now run before any build, so the post-build
uninstrumented gate wording applies only to the serial-windows complete
reference; preview builds still exercise the suite against real
artifacts.

@@ -21,16 +21,16 @@ Key durable, contested choices:
 
 - **The canonical durable log persists every `SessionEvent` losslessly, including `assistant/chunk`.** JSONL storage may encode a consecutive delta run as one packed row, but logical readers reconstruct the exact event boundaries, sequence numbers, and timestamps. `deriveMessages()` skips chunks, and a chunk-filtered rollout (Codex's `policy.rs`) is tempting — but `seq = log.length` and validation of `events[i].seq === i` require a *contiguous* logical log; filtering chunks out would leave holes and break both the contract and resume. A chunk-filtered projection is possible later as a derived view with its own renumbering, but it is NOT the canonical log.
 - **Append-only; a crashed turn is closed, never truncated.** Flushed events are never rewritten. The [semantic checkpoint policy](../bug-fix/2026-07-21-semantic-session-checkpoints.md) drains the request before model dispatch, a recorded top-level call before tool dispatch, and the complete response/result batch after a step; the loop drains the final turn boundary. Because one interrupted turn may contain substantial valid work, cold inspection preserves its contiguous, parseable events and adds risk-classified error results for unanswered assistant calls, a missing `step/end`, and `turn/end` with `{ kind: 'interrupted' }` to the in-memory logical view. `prepare` or `load` commits those closers before returning a recoverable view; the synthetic results keep resumed provider transcripts valid. Only an incomplete final record is discarded during committed repair; a parse error or sequence gap at or before the last real `turn/end` is corruption and makes the session unloadable.
-- **File backend canonical, DB backend a proven drop-in.** `SessionEvent` maps 1:1 onto a row `(session_id, seq, type, time, data)` — `append` is INSERT (in a transaction asserting the contiguous-seq contract), and reads use SELECT … ORDER BY seq. `dsh-session-persistence-sqlite` is exactly this: a `SessionPersistence` subclass with no interface change (opencode runs this exact shape on SQLite/WAL), and it passes the same `runPersistenceContract` suite as the JSONL backend — so the contract holds both backends to identical semantics (lazy materialization, logical interrupted-turn closure, single committed repair, contiguous-seq), expressed once over file bytes and once over rows. Its database carries a dedicated application id and monotonic schema version. A pristine file creates all tables and stamps both header values in one transaction; an unversioned file with any user-defined schema object or application identity, a foreign current-version identity, and every non-current version reject before journal-mode mutation.
-- **Metadata is out-of-log.** Format version, cwd, and lineage are storage concerns, not replayable conversation state, so they live in a `SessionHeader` owned by `dsh-session` and attached to a `Session` via a new readonly `session.header` — never in `SessionEventMap`, never reaching `deriveMessages()`. `createdAt` is non-negative safe-integer Unix epoch milliseconds: live creation and persistence registration reject fractional values, JSONL validates the decoded header, and SQLite stores it in a strict `INTEGER` column. The alternative (a merge-extensible `session/meta` event as log line 0) was rejected: an in-log event would ride along with a seeded/forked session for free, but metadata is not replayable state, so the explicit out-of-log header boundary is the cleaner cost. (The header was originally split into an immutable `SessionHeader` plus a mutable `SessionSummary` whose union was `SessionMeta`; the mutable summary was later removed as dead state — see [Drop the mutable session summary](../simplification/2026-06-19-drop-mutable-session-summary.md).)
+- **The file backend is canonical while the service remains extensible.** `dsh-session-persistence-jsonl` is the sole first-party provider and passes `runPersistenceContract`; the abstract service and coordinator remain available to out-of-tree providers. The [JSONL-only persistence decision](../simplification/2026-08-30-jsonl-only-session-persistence.md) owns removal of the first-party database provider and its deliberate compatibility cut.

 - **`ctx.agents.create()` and `ctx.agents.resume()` are async factories; resume additionally crosses the persistence boundary.** `ctx.agents.resume({ resumeSessionId })` obtains the exact unpublished Session through `ctx.sessionPersistence.prepare()`, publishes it under the persisted id, and continues its projections. The [Session preparation decision](2026-08-05-session-preparation.md) owns reuse between history inspection and resume. The agent-loop does NOT hard-inject `sessionPersistence` (that would pend non-persistent demos forever); `resume` rejects with a clear error when it is absent.
 
 ## Alternatives considered
 
-Each key choice above records its rejected alternative where the choice is stated: a **chunk-filtered canonical log** (Codex's `policy.rs` shape) — breaks the contiguous-seq contract; **truncating a crashed turn** — silently destroys a long autonomous run's real work; an **in-log `session/meta` event as line 0** — metadata is not replayable state; **finite fractional `createdAt` values** — have no producer and diverge from integer Unix-millisecond storage and query columns; **adopting a non-pristine unversioned SQLite file** — can overwrite unrelated objects or identity; **hard-injecting `sessionPersistence` into the loop** — would pend non-persistent demos forever.

-Format versioning: the header carries a `version`; cold reads reject any non-current version. The pre-release session format stays pinned at `SESSION_FORMAT_VERSION = 0` and carries no broad compatibility promise, while the coordinator may own an explicit narrow import upgrade when persisted user data requires it ([pre-identity message recovery](../bug-fix/2026-07-28-load-pre-identity-session-messages.md)). Append-only + flush is robust to partial trailing writes (tolerated during cold preparation) but not to fsync-less power loss mid-line; a DB/WAL backend is the stronger option there.

 ## Consequences
 
-Two new packages and the metadata contract in `dsh-session` (`session.header`, the `create(id?, options?)` signature). Bought: durable resume/fork, a read/replay path, crash tolerance, and host-side session access over the existing event-sourced log, with the backend swappable behind one interface. The reusable `runPersistenceContract` suite holds every backend to the same append-only, contiguous-seq, lazy-materialization, logical-recovery, integer-metadata, and serializability semantics. Persisting the full logical log also settles event fidelity: every `assistant/chunk` survives exactly even when JSONL packs several into one storage row. SQLite initialization either commits its complete owned schema and header identity or leaves no partial schema to strand on the next open.

 - **规范的持久日志无损保留每个 `SessionEvent`，包括 `assistant/chunk`。** JSONL 存储可以将一段连续的增量事件编码为一条打包行，但逻辑读取方会重建精确的事件边界、序号与时间戳。`deriveMessages()` 跳过分片，而过滤分片的方案（Codex 的 `policy.rs`）很有吸引力，但 `seq = log.length` 以及 `events[i].seq === i` 验证要求*连续*的逻辑日志；过滤掉分片会留下空洞，同时破坏约定和恢复功能。基于分片过滤的投影可以作为派生视图在后续实现（带有自己的重新编号），但它不是规范日志。

 ## Problem
 
-`dsh-session-persistence-jsonl` and `dsh-session-persistence-sqlite` intentionally prove the same `SessionPersistence` contract over different storage media, but their write-path orchestration was duplicated: per-session state, `session/created` adoption, backend-specific prefix reads, write-behind control, per-id operation serialization, HMR seeding, and dispose drains. The pure seed-prefix collision and serializability guards had already moved into the Service Definition package; the remaining orchestration was still correctness-heavy and received the same fixes twice. Only the storage primitives (write bytes vs. INSERT rows) differed.
+The JSONL provider needs correctness-heavy write orchestration around its storage primitives: per-Session state, `session/created` adoption, prefix reads, write-behind control, per-id operation serialization, HMR seeding, and dispose drains. Keeping that lifecycle in the Service Definition prevents an out-of-tree provider from copying it. The removed first-party database provider demonstrated the duplication cost; the [JSONL-only persistence decision](../simplification/2026-08-30-jsonl-only-session-persistence.md) owns its removal.
 
 ## Decision
 
-Extract a backend-agnostic `PersistenceCoordinator` into `dsh-session-persistence`. The coordinator owns the orchestration once; each first-party backend composes one (`new PersistenceCoordinator(ctx, this)`), implements a small `PersistenceBackend` hook interface, and delegates its stateful public methods (`create`/`append`/`prepare`/`load`/`inspect`/`readFrom`) to it. Backend-owned metadata and revision listing bypass the coordinator.

Backend-owned metadata and revision listing bypass the coordinator.
 
 Composition, not inheritance. The coordinator is a concrete class the backend holds, not a base class the backend extends. The risk that a coordinator makes unusual backends fight an inheritance hierarchy is avoided: a backend exposes only the hooks and cannot reach the coordinator's private orchestration state. A third-party backend MAY still implement the abstract service directly without the coordinator, including immutable logical inspection and the default preparation fallback through `load`.

 Five required members plus optional empty-materialization and lifecycle hooks form the only boundary between the coordinator and storage:
 
 - `name` — backend label for the dispose-failure `AggregateError`.
-- `loadStored(id)` — read one stored prefix by id across every storage scope (every JSONL project directory; SQLite's id is globally unique). Preparation, logical load/inspection, physical suffix reads, live adoption, and the create-collision probe share this lookup. The coordinator asserts the returned id and rejects a stored/live cwd mismatch before repair or state publication.

The coordinator asserts the returned id and rejects a stored/live cwd mismatch before repair or state publication.
 - `appendBatch(meta, events, isMaterialized)` — durably append a contiguous batch, lazily materializing the session ATOMICALLY when not yet materialized. Ordinary creation therefore cannot leave an abandoned materialized-but-empty session.
 - `materializeHeader?(meta)` — explicitly persist a header-only session for `SessionPersistence.ensureMaterialized(session)`. This is reserved for a lifecycle frontend that treats an empty session itself as a resumable durable resource; [standard ACP automation controls](../feature/2026-08-22-standard-acp-automation-controls.md) are the first consumer. Backends that support that lifecycle implement the hook; lazy creation remains the default.
-- `commitRepair(meta, tornMarker, closers)` — make a crash repair durable: truncate the torn tail (iff `tornMarker !== undefined`) and append `closers`. **NOT required to be atomic** — JSONL legitimately truncates-then-appends in two fsync'd steps, SQLite does DELETE+INSERT in one transaction. Used by `prepare`/`load` (truncate + synthetic closers) and live-adoption (truncate only, `closers = []`).

+- `close?()` — optional lifecycle teardown for a provider with owned resources; JSONL omits it. The dispose effect awaits it after the quiescence drain so a close failure never masks a drain error.
 
 ### The opaque torn marker
 
-The single design choice that keeps the seam clean: the crash-repair "where is the torn tail" token is OPAQUE to the coordinator. The coordinator computes the synthetic closers (it owns `interruptedTurnClosers` from `dsh-session`), but it only ever tests `tornMarker !== undefined` and passes the value straight back to `commitRepair` — it never inspects it. Each backend picks its own marker type: JSONL carries the byte offset to truncate to plus any complete events decoded from an incomplete final frame, while SQLite carries the seq to delete from. The coordinator therefore knows neither byte lengths nor frame recovery state.

 ## Testing
 
-The shared `runPersistenceContract` (public-API contract) runs for every backend and proves that `inspect` balances an interrupted logical view without changing storage or revisions before `prepare` or `load` commits recovery. `runCoordinatorContract` (`tests/coordinator-contract.ts`) covers adoption, HMR, collision, session and backend disposal drains, and crash-tail repair through an in-memory reference, JSONL, and SQLite. `persistence.spec.ts`, `preparations.spec.ts`, and `write-behind.spec.ts` cover preparation reuse and reservation, bounded prepared-state eviction, fixed-window follow-up batches, live-controller cleanup, same-id chain-tail races, failed-batch retry, and close ordering. The per-backend specs retain storage mechanics only. A through-coordinator torn-tail repair test per real backend keeps the opaque-marker branch covered because the contract crash case produces synthetic closers without a torn marker.

 - **A base class the backends extend** — rejected for composition: a backend exposes only the hooks, cannot reach the coordinator's private orchestration state, and a third-party backend may still implement the abstract service directly without the coordinator at all.
-- **A wider hook API** — each candidate hook folds away: there is no scope-specific live lookup because `loadStored` plus the coordinator's cwd check preserves the collision boundary, no storage-locator generic because validated JSONL metadata reproduces its path while SQLite is already id-bound, no separate `materialize` hook because the first batch must commit atomically with materialization, no separate create-collision probe because it is `loadStored(id) !== undefined`, and no coordinator pass-through for `list()` because listing needs none of the orchestration.

 ## Consequences
 
-The coordinator adds one indirection, an opaque torn marker, detached session-retirement tasks, and bounded prepared Session state, but centralizes correctness-heavy orchestration previously duplicated by every backend. Session disposal remains an observe-only event, so the session owner does not await persistence retirement; the coordinator contains failures, preserves pending events in the live controller, and makes backend teardown the quiescence boundary. Its hook surface stays narrow: identity, adoption, collision checks, preparation, and immutable inspection reuse `loadStored`; materialization stays atomic inside `appendBatch`; and listing bypasses the coordinator. Read models use `inspect` rather than `load`, so observing a persisted open turn does not commit interruption closers; the [Session preparation decision](2026-08-05-session-preparation.md) owns reuse, reservation, and publication. New backends implement storage primitives rather than copy the bounded write lifecycle.

 ## 问题
 
-`dsh-session-persistence-jsonl` 与 `dsh-session-persistence-sqlite` 有意在不同存储介质上证明同一份 `SessionPersistence` 约定，但它们重复实现了写入路径编排：每会话状态、`session/created` 接管、后端特定的前缀读取、write-behind（延迟写入）控制、按 id 串行执行操作、HMR（热模块替换）种子注入与 dispose（资源释放）排空。纯粹的种子前缀碰撞检查与可序列化守卫已迁入 Service Definition 包；剩余的编排仍然对正确性要求很高，且同样的修复被应用了两次。唯一的差异在于存储原语（写字节 vs. INSERT 行）。
+JSONL provider 需要在其存储原语周围执行对正确性要求很高的写入编排：逐 Session 状态、`session/created` 接管、前缀读取、write-behind 控制、按 id 串行执行、HMR 种子注入与 dispose 排空。把该生命周期放在 Service Definition 中，可以避免仓库外 provider 重复实现。已删除的 first-party 数据库 provider 证明了这种重复成本；其删除由 [JSONL-only 持久化决策](../simplification/2026-08-30-jsonl-only-session-persistence.zh.md)负责。
 
 ## 决策
 
-将一个后端无关的 `PersistenceCoordinator` 提取到 `dsh-session-persistence` 中。协调器统一拥有编排逻辑；每个第一方后端组合一个协调器实例（`new PersistenceCoordinator(ctx, this)`），实现一个小型 `PersistenceBackend` 钩子接口，并将其有状态的公开方法（`create`/`append`/`prepare`/`load`/`inspect`/`readFrom`）委托给协调器。由后端拥有的元数据与修订版本列举会绕过协调器。

 组合，而非继承。协调器是后端持有的具体类，不是后端继承的基类。协调器让非常规后端与继承层级作斗争的风险由此规避：后端只暴露钩子，无法触及协调器的私有编排状态。第三方后端仍然可以完全不使用协调器、直接实现抽象服务，包括不可变逻辑检查，以及通过 `load` 实现的默认准备回退。

 五个必需成员加可选的空会话实体化与生命周期钩子，构成协调器与存储之间唯一的边界：
 
 - `name`——后端标签，用于 dispose 失败时的 `AggregateError`。
-- `loadStored(id)`——按 id 跨所有存储范围读取一个已存储前缀（JSONL 的所有项目目录；SQLite 的 id 全局唯一）。准备、逻辑加载/检查、物理后缀读取、存活会话接管与创建碰撞探测共用此查找。协调器会断言返回的 id，并在修复或发布状态之前拒绝已存储记录与存活会话的 cwd 不匹配。

 - `appendBatch(meta, events, isMaterialized)`——持久追加一个连续批次，在尚未物化时原子地惰性物化会话。因此，普通创建不会留下被放弃的已物化空会话。
 - `materializeHeader?(meta)`——为 `SessionPersistence.ensureMaterialized(session)` 显式持久化仅含 header 的会话。它只供把空会话本身视为可恢复持久资源的生命周期前端使用；[标准 ACP 自动化控制](../feature/2026-08-22-standard-acp-automation-controls.zh.md)是第一个 consumer。支持该生命周期的后端实现此钩子；惰性创建仍是默认行为。
-- `commitRepair(meta, tornMarker, closers)`——使崩溃修复持久化：截断损坏的尾部（当且仅当 `tornMarker !== undefined`）并追加 `closers`。**不要求原子性**——JSONL 合理地分两步 fsync（先截断再追加），SQLite 在一个事务中完成 DELETE+INSERT。用于 `prepare`/`load`（截断 + 合成收尾事件）和存活会话接管（仅截断，`closers = []`）。

 ### 不透明的 torn marker
 
-保持 seam 整洁的唯一设计选择：崩溃修复中「损坏尾部在哪里」的 token 对协调器是不透明的。协调器计算合成收尾事件（它拥有来自 `dsh-session` 的 `interruptedTurnClosers`），但它只测试 `tornMarker !== undefined` 并将值原样传回 `commitRepair`——从不检视其内容。每个后端选择自己的 marker 类型：JSONL 携带要截断到的字节偏移，以及从不完整最终帧中解码出的任何完整事件；SQLite 则携带要从其开始删除的 seq。协调器因此既不了解字节长度，也不了解帧恢复状态。

 ## 测试
 
-共享的 `runPersistenceContract`（公开 API 约定）为每个后端运行，并证明 `inspect` 会配平被中断的逻辑视图但不改变存储或修订版本，随后由 `prepare` 或 `load` 提交恢复。`runCoordinatorContract`（`tests/coordinator-contract.ts`）通过内存参考实现、JSONL 与 SQLite 覆盖接管、HMR、碰撞、会话与后端 dispose 排空和崩溃尾部修复。`persistence.spec.ts`、`preparations.spec.ts` 与 `write-behind.spec.ts` 覆盖准备复用与预留、有界准备状态淘汰、固定窗口后续批次、存活控制器清理、同 id 链尾竞态、失败批次重试与关闭顺序。各后端自身的测试规格只保留存储机制。每个真实后端都有一个经由协调器的崩溃尾部修复测试，以覆盖不透明 marker 分支，因为约定中的崩溃用例会产生合成收尾事件，却不会产生 torn marker。

 ## 曾考虑的替代方案
 
 - **后端继承的基类**——否决，改用组合：后端只暴露钩子，无法触及协调器的私有编排状态，且第三方后端仍可完全不使用协调器、直接实现抽象服务。
-- **更宽的钩子 API**——每个候选钩子都被折叠掉：没有限定存储范围的存活会话查找，因为 `loadStored` 加上协调器的 cwd 检查即可维持碰撞边界；没有存储定位器泛型，因为经验证的 JSONL 元数据可还原其路径，而 SQLite 已按 id 绑定；没有单独的 `materialize` 钩子，因为首批事件必须与物化原子提交；没有单独的创建碰撞探测，因为它就是 `loadStored(id) !== undefined`；`list()` 也不经由协调器透传，因为列举不需要任何编排。

 ## 后果
 
-协调器增加了一层间接、一个不透明的 torn marker、脱离会话生命周期的退役任务，以及有界的已准备 Session 状态，但将此前每个后端重复的、对正确性要求很高的编排逻辑集中到一处。会话 dispose 仍是仅观察事件，因此会话所有者不会等待持久化退役；协调器会收容失败、在存活控制器中保留待处理事件，并以后端 teardown 为完全停稳边界。其钩子面保持窄小：标识校验、接管、碰撞检查、准备与不可变检查共用 `loadStored`；物化保持在 `appendBatch` 内原子完成；列举绕过协调器。读模型使用 `inspect` 而非 `load`，因此观察已持久化但仍开放的轮次时不会提交中断收尾事件；复用、预留与发布由 [Session 准备阶段决策](2026-08-05-session-preparation.zh.md)定义。新后端只需实现存储原语，而无需复制有界写入生命周期。

It is spent on first use, matching the workspace picker beside it. What a running session runs is then a read-only label in its header: a control there would promise a switch the host refuses outright.

The settled three-rung ladder later reuses this cache opportunistically, read-only, as its second rung — no write-back, no orchestration, skipped when absent.

 ## Problem
 
-Streaming responses can emit many `assistant/chunk` events in a short interval. The persistence coordinator previously scheduled a backend append as soon as an idle queue received one event. Events arriving while that append was active shared a follow-up batch, but a fast backend could still produce many small durable appends. Each JSONL append creates and syncs a Zstandard frame or raw suffix, while each SQLite append opens and commits a transaction and increments the session revision.

 Repository fixtures make the logical volume concrete. Decoding the current packed rows in [`goal-multi-turn-actions`](../../../../snapshots/web/goal-multi-turn-actions/session.jsonl) yields 2,098 events: 2,017 chunks (96.1%). Their unpacked JSONL lines occupy 332,647 of 379,225 event bytes (87.7%), while chunk packing reduces the committed file to 89,176 bytes and 182 storage rows, including 23 packed chunk rows. [`permission-policy-context`](../../../../snapshots/web/permission-policy-context/session.jsonl) yields 813 events: 746 chunks (91.8%) and 118,935 of 184,821 unpacked event bytes (64.4%); its packed file is 84,917 bytes and 123 storage rows, including 14 packed rows. These are tracked deterministic fixtures, not a production workload distribution, but they demonstrate why deleting chunks would reduce logical volume and why the existing packed-row layout already removes much of their JSON envelope cost.
 
-SQLite stores one row per logical event, so those same logical logs would retain 2,098 and 813 event rows respectively; batching does not change those counts. JSONL writes one Zstandard frame and fsync per durable append batch, while SQLite performs one transaction and one session-revision increment per batch. Runtime files do not record former append boundaries, so fixture row counts cannot honestly be presented as fsync or transaction counts.
+JSONL writes one Zstandard frame and fsync per durable append batch. Runtime files do not record former append boundaries, so fixture row counts cannot honestly be presented as fsync counts.
 
 The scheduling bound is deterministic. With an immediately resolving sink, the former immediate controller could issue one append for each event arriving after the previous append completed. A controller test admits 20 events 10 ms apart: the 200 ms fixed window hands all 20 to one append. This is a 20-to-1 reduction for that cadence, not a universal ratio. Sparse events, mandatory flushes, slow prior writes, and different arrival rates produce different batch sizes.
 
 ## Decision
 
-The first-party JSONL and SQLite plugins expose `writeBatchMaxDelayMs`, a positive integer no greater than Node's timer limit. Its default is `200`. Each plugin resolves the value at load and passes it to `PersistenceCoordinator`; the coordinator remains the single owner of batching behavior.

 Each live Session receives a package-private `SessionWriteBehind`. When its pending queue changes from empty to non-empty, the controller starts one fixed window. Later events join that batch without resetting the deadline: this is bounded coalescing, not debounce. When the deadline expires, the controller hands the complete pending prefix to the existing per-id serialization and `appendBatch` path. At most one write for a Session is active. Events admitted during that write form a new pending prefix with their own fixed deadline; if that deadline expires before the active write completes, the new prefix starts immediately after it.

 ## Consequences
 
 High-frequency event bursts normally produce fewer durable append operations while preserving the exact logical event count. The reduction depends on arrival rate and backend latency: a burst inside one 200 ms window becomes one batch, while mandatory flushes and sparse events can still produce small batches.
 
-This decision does not cap pending event count or bytes behind a slow backend, and it does not reduce SQLite rows or the decoded logical log. A demonstrated memory bound or logical-retention policy would require its own failure and replay contract rather than another hidden timer rule.

 An admitted event can remain only in memory during the configured window, and then while scheduling or backend work is outstanding. Deployments choose a smaller value for a narrower ordinary loss window or a larger value for stronger batching. Explicit durability boundaries remain unchanged and bypass the wait.

-SQLite 每个逻辑事件存储一行，因此同样的逻辑日志会分别保留 2,098 和 813 个事件行；批处理不会改变这些数量。JSONL 每个持久化追加批次会写入一个 Zstandard 帧并执行一次 fsync，SQLite 每个批次会执行一次事务并递增一次会话修订版本。运行时文件不记录原有追加边界，因此不能把 fixture 的存储行数当作 fsync 或事务次数。
+JSONL 每个持久化追加批次会写入一个 Zstandard 帧并执行一次 fsync。运行时文件不记录原有追加边界，因此不能把 fixture 的存储行数当作 fsync 次数。
 
 调度上界是确定的。当写入端会立即完成每次操作时，原来的即时控制器可能对每个在前一次追加完成后到达的事件分别发起一次追加。一个控制器测试以 10 ms 的间隔接纳 20 个事件：200 ms 固定窗口会把全部 20 个事件交给一次追加。对于这种到达节奏，追加次数从 20 次降至 1 次，但这不是普遍比例。稀疏事件、强制 flush、较慢的前序写入和不同到达速率都会产生不同的批次大小。
 
 ## 决策
 
-第一方 JSONL 与 SQLite 插件公开 `writeBatchMaxDelayMs`，其值必须是一个不超过 Node 计时器上限的正整数，默认值为 `200`。每个插件都会在加载时解析该值，再传给 `PersistenceCoordinator`；批处理行为仍只由协调器负责。

 每个活跃的会话都有一个包私有 `SessionWriteBehind`。当其待处理队列从空变为非空时，控制器会启动一个固定窗口。后续事件加入该批次但不会重置截止时间：这属于有界合并，而不是防抖。截止时间到达后，控制器会把完整的待处理前缀交给现有的按 id 串行化机制，并沿 `appendBatch` 路径写入。同一会话同时最多有一个活跃写入。该写入期间接纳的事件会形成新的待处理前缀，并拥有自己的固定截止时间；如果该截止时间在活跃写入完成前到期，新前缀会在前一次写入完成后立即开始写入。

 `session/flush` 会取消剩余等待，并充当共享的完全停稳屏障。它会在完成前等待活跃写入尝试，并排空屏障运行期间接纳的每个事件。会话退役与后端 dispose（资源释放）共用该屏障，因此生命周期 teardown 绝不会等待批处理计时器。检查点策略仍会在模型请求与顶层工具副作用之前设置强制屏障。
 
-每个事件仍会按原有顺序和形态持久化。控制器会在接纳时复制每个事件；任何 `assistant/chunk`、`seq`、`time`、surface 元数据或存储记录都不会被删除或重写。因此，JSONL 可以在一个追加帧中编码更多事件，SQLite 可以在一个事务中插入更多事件行，而无需改变任一种磁盘格式或 schema 版本。

 后台追加失败后，控制器会把完整批次恢复到所有较新的待处理事件之前，报告一次该失败，并暂停自动重试。随后新接纳的第一个事件会开启新的固定窗口；显式 flush、退役或 dispose 会立即重试，如果故障再次发生，则会向调用方暴露该故障。这可以避免计时器驱动的失败循环，同时保留现有可恢复的 flush 边界。

 ## 后果
 
 高频事件突发通常会减少持久化追加操作，同时保持逻辑事件数量完全不变。减少幅度取决于事件到达速率和后端延迟：位于同一 200 ms 窗口内的突发事件会成为一个批次，而强制 flush 与稀疏事件仍可能产生小批次。
 
-本决策不会限制因后端缓慢而积压的待处理事件数量或字节数，也不会减少 SQLite 行数或解码后的逻辑日志。若要建立经过验证的内存上界或逻辑保留策略，就必须为其另行定义失败与回放约定，而不是再引入一条隐式计时器规则。

 接纳后的事件在配置窗口内可能只存在于内存中，此后在等待调度或后端工作完成期间也可能如此。部署可以选择较小的值以缩短普通丢失窗口，也可以选择较大的值以加强批处理。显式持久性边界保持不变，并会绕过等待。

An external informational event carrying the marker remains reloadable, while an unknown required event refuses resume. The unknown-type guard is read-side only: `appendCore` keeps rejecting retired legacy shapes but does not vocabulary-check new types, because an append-time refusal would stall a live session's durability mid-flight, which costs more than a loud refusal at the log's next load. The JSONL backend additionally refuses a foreign version from the raw header line before validating this format version's header shape or decoding any event row, so a structurally different future format still reports the upgrade direction instead of "corrupt"; SQLite gates whole-file structure through its own `SCHEMA_VERSION` pragma first.

The original 105-session corpus showed that JSONL level-19 compression made full writes and forks more than twice as slow. The earlier SQLite page-size experiment predated shared-dictionary row compression and showed negligible savings, so it did not establish the best page size for the current row distribution.

 ### Storage encoding stays physical and independently decodable
 
-JSONL stores strictly increasing `sourceEventSeqs` as mixed scalar values and inclusive ranges; other orders remain verbatim. SQLite stores the same arrays as tagged zigzag-delta or `(start, count)` varints, choosing the smaller encoding. Both readers restore the original `number[]` before exposing an event.
-
-SQLite uses an internal integer `sessions.id` and keeps the public session id once in `sessions.session_key`, so event rows and their primary key do not repeat a text identifier. Each `events.data` value remains independently decodable: the writer tries level-3 Zstandard with the packaged 64 KiB raw-content dictionary and retains SQLite text when compression is not smaller. The dictionary bytes are part of schema 20 and a test pins their SHA-256 digest; replacing them requires another schema-version bump.
+JSONL stores strictly increasing `sourceEventSeqs` as mixed scalar values and inclusive ranges; other orders remain verbatim. Reading restores the original `number[]` before exposing an event.
 
 ### JSONL uses the standard Zstandard level
 
 The JSONL writer keeps one checksummed Zstandard frame per durable append batch but uses the compressor's standard level. Lossless `sourceEventSeqs` range encoding remains active. Frames stay independently decodable for suffix reads and torn-tail recovery; only the expensive level-19 search is removed.
 
-### New SQLite databases use 64 KiB pages
-
-The SQLite provider sets `page_size=65536` before initializing a pristine schema-20 database. An established schema-20 database retains its current page size because SQLite ignores the pragma after allocation.

-The page size is part of schema 20's fixed physical layout and is applied through the package's closed SQL resources like the other fixed SQLite pragmas.

In the paired run, full write, full read, and suffix read change by -0.5%, -0.4%, and -3.8%; fork changes by -14.8%. The space gain therefore comes from better large-row page utilization rather than a smaller index or omitted data, without a measured latency regression.
-
 ## Alternatives considered
 
 **Keep JSONL level 19.** Rejected. On the expanded corpus it saves another 12.1% relative to default-level frames but increases full-write time by 67.0% and fork time by 129.8%, while complete and suffix reads differ by less than 1%. Default-level frames plus provenance ranges retain a 14.1% size reduction relative to master without a material latency regression.
 
 **Compress one whole JSONL log as a single frame.** Rejected. It improves cross-batch compression but makes suffix reads decompress from the start and removes batch-local torn-tail recovery.
 
-**Keep 4 KiB SQLite pages.** Rejected for pristine databases. The current compressed-row distribution retains 9.26% more bytes because large compressed records leave more unusable space across 4 KiB B-tree pages. Existing databases keep their page size to avoid a historical rewrite.
-
-**Remove ROWID from `events`.** Rejected. The composite primary key becomes the table B-tree key and repeats through internal pages; the 105-session comparison produced a larger database than ordinary ROWID tables.
-
 **Deduplicate event content.** Rejected. Message restatements and tool arguments can be reconstructed only under assumptions that compaction, retries, and pruning may invalidate. Physical compression preserves every event without adding reconstruction semantics.
 
-**Use per-session SQLite files or DuckDB.** Rejected for the hot store. Per-session files lose cross-session queries, while DuckDB's OLAP write model fits cold batch analysis rather than durable append batches and low-latency suffix reads.
-
 ## Consequences
 
-JSONL keeps the low-cost provenance optimization without the level-19 write and fork penalty. SQLite exchanges approximately 5–26% more time across the measured operations for a 46.8% retained-size reduction; its full write remains materially faster than JSONL, and its suffix read remains much faster. Its complete read and fork are slightly slower than default-level JSONL on this expanded corpus.
-
-New SQLite databases use 64 KiB WAL frames and cache pages. Small databases may reserve more bytes for sparsely populated schema and metadata pages, while the measured multi-session workload gains substantially better `events` page utilization. Schema 20 rejects every other schema version rather than migrating it.

 ## 考虑过的替代方案
 
 **保留 JSONL level 19。** 不予采用。在扩展语料上，它相对默认级别 frame 可再减少 12.1%，却让完整写入增加 67.0%、fork 增加 129.8%，而完整读取与后缀读取的差异都不足 1%。默认级别 frame 配合来源区间后，相对 master 仍能缩小 14.1%，且没有实质性延迟退化。
 
 **把整份 JSONL 日志压成单个 frame。** 不予采用。该方案可改善跨批次压缩，但后缀读取必须从头解压，也会失去按批次恢复撕裂尾部的能力。
 
-**新建 SQLite 数据库继续使用 4 KiB page。** 不予采用。当前压缩行分布会在 4 KiB B-tree page 之间留下更多不可用空间，使保留字节增加 9.26%。已有数据库保留其 page size，避免改写历史数据。
-
-**从 `events` 移除 ROWID。** 不予采用。复合主键会成为表 B-tree 键并在内部 page 中重复；105 会话对比所得数据库大于使用普通 ROWID 的表。
-
 **对事件内容去重。** 不予采用。消息复述与工具参数只能在依赖重建假设时删除，而 compaction、重试和修剪可能让这些假设失效。物理压缩保留每个事件，不增加重建语义。
 
-**使用逐会话 SQLite 文件或 DuckDB。** 不用于热存储。逐会话文件会失去跨会话查询，DuckDB 的 OLAP 写入模型则更适合冷批量分析，而不是持久 append 批次与低延迟后缀读取。
-
 ## 后果
 
-JSONL 保留低成本来源优化，同时避开 level-19 的写入与 fork 代价。SQLite 以实测各项操作约 5–26% 的额外耗时换取 46.8% 的保留体积缩减；其完整写入仍明显快于 JSONL，后缀读取也仍快得多。在这份扩展语料上，完整读取与 fork 略慢于默认级别 JSONL。
-
-新建 SQLite 数据库使用 64 KiB WAL frame 与 cache page。小型数据库可能为稀疏的 schema 与元数据 page 预留更多字节，而实测的多会话工作负载显著改善了 `events` page 利用率。Schema 20 会拒绝其他所有 schema 版本，而不是迁移它们。

-JSONL lookup selects a physical log from the requested session id across project directories, while the parsed `SessionHeader` supplies the metadata used by later repair and append operations. Without binding those two facts, a log selected for session A can declare session B's id or cwd and redirect a repair or later append to B's path. The project scan also needs a defined result when the same encoded id exists in more than one project directory.

 ## Problem
 
-The identified immutable message change replaced four durable event payloads with complete message values. Existing v0 JSONL and SQLite sessions still held the immediately preceding shapes: direct `content`/`source` on user and steering events, `content`/`provenance` on assistant events, and `callId`/`content`/`isError` on tool results. Their headers still matched `SESSION_FORMAT_VERSION`, but current-shape validation rejected them before resume could construct a live `Session`.

 Selector rows fold nothing but titles, and everything else a row shows comes from metadata:
 
 - Titles come from the projection system: `session-title` already registers a `title` unit, so a live row reads the registry snapshot, a persisted row reads the durable checkpoint row (`sessionProjectionCache.cachedSnapshot`, one file read per session), and only a row without a usable checkpoint pays a `coldSnapshot` — checkpoint plus a `readFrom` tail, written back so the next scan is zero-I/O. Cold reads are bounded by the TUI `resumeScanConcurrency` config. A composition without the cache falls back to one bounded `readTitleSnapshots` batch over the logs; either path isolates a per-row failure into the disabled "Unreadable session" fallback.
-- The activity timestamp never reads a log: a live session uses its last in-memory event time; a persisted session stats the artifact named by the optional `sessionPersistence.locate()` (mtime), falling back to the header's creation time when the backend locates no per-session artifact (SQLite) or the stat fails. Any append moves the mtime, so a mere pickup boundary now floats a browsed session up — accepted as the price of a metadata-only timestamp.

 The selector overlay opens synchronously when `/resume` dispatches, before the scan settles: an `undefined` candidate set renders a "Loading sessions…" placeholder, the picker owns terminal input from its first frame, Enter reports that sessions are still loading, and Escape cancels. Closing the overlay aborts the scan through the `AbortSignal` the query methods accept; a signal-ignoring backend's late settlement is dropped by a staleness check. The finished scan swaps rows in through `setCandidates` (clearing a stale still-loading error) without replacing the overlay; a queued activation behind a closing predecessor receives an already-scanned set at construction; one catch spans listing, titles, and mtimes, so any scan failure closes the overlay and reports a notice rather than stranding the loading placeholder.

 A keyless full-loop integration drives the real agent loop, JSONL persistence, tool-bash, and bash-local on the first turn. The child prints `DSH_HOME`, `DSH_SHELL`, session id, JSONL target, and an inherited stale sentinel; the test verifies current values, absence of the stale variable, pre-flush file absence, and the eventual persisted header. Snapshot coverage pins the generic bash description in the recorded request header. No with-key test is required because the contract is deterministic local execution rather than model choice.

+- Titles survive JSONL persistence, replay, and fork inheritance without a separate mutable record.
 - Web title delivery stays incremental and log-backed without a title index or persisted-list scan; cold list rows improve after attach.
 - A fallback appears immediately. Each fresh Web session adds one first-prompt auxiliary call; other compositions choose whether better titles justify model cost and whether later prompts should retitle a session.
 - Auxiliary request records and late accepted titles consume event seqs without consuming turn numbers, so persistence exposes both attempted dispatches and accepted updates even though model history and KV-cache identity do not change.

 Everything else — including a form this UI version does not present, a form absent from the source, and a `catalog` whose entries are unusable — renders the **opaque** body: the model-facing text with its real line breaks, then the remaining source data as fields. Opaque is the documented default; the contract assigns these unsupported cases to it. A resumed, forked, or foreign log must render whether or not its producer is mounted here, which is also why the classification lives in the durable source rather than in a client-side table keyed by producer.

The archive name is `dsh-session-<sanitized-id>.zip` and archive paths sanitize ids before they can shape entries.

 `session/new` explicitly asks persistence to materialize the live session header without inventing a session event, so even an empty session can be closed, listed, and resumed. Other frontends retain the persistence seam's lazy default and leave abandoned empty sessions unmaterialized. `session/resume` rejects active ids and non-top-level or unknown persisted ids, verifies the requested canonical `cwd` before Agent composition, restores the durable session without replaying it to the client, and mounts the MCP declarations supplied by that request. `session/close` leaves the durable log available for a later process.
 
-Persistence deliberately treats `create(meta)` as a live registration: JSONL creates no artifact and SQLite creates no row until the first event append. That default removes abandoned empty sessions, but ACP cannot inherit it because `session/new` publishes a session identity before any prompt and the process may stop after the success response without receiving `session/close`. The bridge materializes only after Agent and MCP composition succeeds and before returning `session/new`; failed composition remains residue-free, while every returned id survives restart.

 Those source features clear on the 22.x line at **22.18**, but the installed Pi adapter dependency raises the advertised LTS floor. `@deepseek-ai/dsh-llm-pi-ai` depends on `@earendil-works/pi-ai@0.79.3`, whose package declares `engines.node >=22.19.0`, so the LTS floor is **22.19**. The 24.x branch remains `>=24.0.0`. The disjoint range excludes Node 23 entirely: Node 23.0–23.5 still has at least one flagged source feature, and the 23 line is non-LTS/EOL, so advertising `>=23.6` would add a dead release line and a CI leg no deployment should use.

Its built-bin smoke starts only after every other observational gate settles; the smoke's `needs` edge still requires a successful build, while its `after` edges preserve the diagnostic after another gate fails. This keeps bounded real-application startup measurements from competing with tool-catalog, NodeNext, package, and documentation processes. The SQLite busy-journal pacing fixture injects two busy results followed by success under the normal busy budget and observes each inter-attempt delay, keeping schema-setup scheduling outside its timing assertion.

 The 16-core allocation is the measured capacity point for this inventory. Six-worker coverage trials produced complete passes in 6 minutes 27 seconds and 7 minutes 50 seconds, while exact-head trials with four, three, and two concurrent workers inside one instrumented Vitest process exposed unreliable fixtures and worker exits. Separate single-worker child processes retain process isolation. Historical sixteen-shard samples reduced instrumented coverage to 112.66–122.01 seconds. The pull-request coverage job schedules four instrumented children plus two exempt workers after the build, while the self-hosted complete reference runs its unsharded coverage gates serially with one worker. A six-partition pull-request profile creates enough process and type-aware lint contention to violate bounded test deadlines. Sixteen instrumented shards plus two exempt workers would exceed a 16-core allocation before system overhead. A 32-core comparison reduced aggregate gate time by only 1.47 seconds and still triggered the CJS-lexer fatal inside a fork worker, so additional cores did not provide a reliable wall-clock improvement.
 
 The first native run exposed two failures hidden by the compatibility lane. Documentation projection tests derived an image basename by splitting only on `/`; they now use Node's platform basename. Chokidar consumers received `%TEMP%` through the `C:\\Users\\RUNNER~1` 8.3 alias while libuv returned the long directory name, tripping its Windows event-path assertion. Shared settings and credentials watchers, plus Cordis module and exact-config HMR, now canonicalize the existing native watch base or deepest existing ancestor before opening the watcher and preserve a missing suffix, while file access and diagnostics retain the configured path. Module HMR attaches listeners and awaits the main watcher's ready event before plugin startup settles, so an immediate post-boot edit cannot race the initial scan. HMR acceptance derives expected identities through the same asynchronous native realpath operation, avoiding a synchronous Windows spelling that can retain the 8.3 alias.
 
-Portable filesystem fixtures derive paths with `node:path`, compare native realpath identities, preserve file URLs at Node launcher boundaries, normalize only API-owned separators or line endings, and use filenames legal on every host. POSIX-only signal, mode-bit, unreadability, and writer-lock cases are platform-gated; portable failure contracts instead assert structured error codes, rollback, last-good state, atomic replacement, and absence of temporary residue through conflicts available on every host. Credentials permission validation uses an invalid-path fixture whose pre-lookup `ERR_INVALID_ARG_VALUE` is non-absence on every host, rather than depending on whether a file ancestor produces `ENOTDIR` or `ENOENT`. Worker-death fixtures drive real termination from the host after observing their protocol preconditions instead of calling `process.exit()` inside a nested Windows Worker; this preserves the worker-exit contract without exposing the enclosing Vitest fork to Node's process-wide native exit assertion. Stress and integration workloads keep their original assertions and receive explicit bounded time budgets where Windows instrumentation or process teardown can exceed Vitest's default ceiling. The randomized SQLite differential property retains all 100 seeded runs and uses a 120-second Windows budget because simultaneous native jobs can contend for the shared runner host; POSIX keeps the 60-second budget.

 Native watchers use `canonicalizeWatchPath()` to realpath the deepest existing ancestor, prove it is an enumerable directory when a suffix is missing, and restore that suffix. This prevents Windows 8.3 aliases from being mixed with long-form libuv events and preserves `ENOTDIR` for a regular-file ancestor on every host. Settings, credentials, skill roots, and Cordis HMR retain configured paths for discovery and diagnostics; module HMR uses the canonical spelling for Node's load-cache identity, attaches listeners, and awaits its main watcher before plugin startup settles, so an immediate post-boot edit cannot race the initial scan. A skill root that is itself a symbolic link remains unexpanded when `watchFollowSymlinks: false`, allowing Chokidar to enforce that boundary.

 ## Decision
 
-Delete the mutable session summary entirely. `SessionSummary` and the `SessionMeta` name are removed; the metadata a backend stores and returns is just `SessionHeader`. `SessionPersistence.update()` is removed from the abstract service and every backend. JSONL loses the whole sidecar machinery (`writeSidecar`/`readSidecar`/`touchSummary`/`removeSidecars`/`sidecarPath` and the load/list overlays); SQLite drops the `updated_at`/`title`/`first_prompt` columns and the per-append `updated_at` bump, and its `SCHEMA_VERSION` goes `1 → 2`.
+Delete the mutable session summary entirely. `SessionSummary` and the `SessionMeta` name are absent; the metadata a backend stores and returns is just `SessionHeader`. `SessionPersistence.update()` is absent from the abstract service. The shipped JSONL provider has no summary sidecar machinery (`writeSidecar`/`readSidecar`/`touchSummary`/`removeSidecars`/`sidecarPath` or load/list overlays), and an out-of-tree provider implements the same summary-free service contract.
 
 Anything the summary was meant to provide is **derivable from the append-only log** when a consumer actually needs it (`firstPrompt` = first `user/message`; recency = the last event's `time` or the file mtime) or already lives in the immutable header (`createdAt`, `cwd`). The one thing *not* derivable — a user-*edited* title — had no implementation and is pure YAGNI; it can return as its own log event or header field if a real feature ever needs it.
 
-The removal narrows a public service contract and an on-disk format across two backends; the summary was a deliberate forward-looking design, not an accident; and `SessionHeader` now stands where the original Agent Note described `SessionMeta`, which is why the summary vanished. It also unblocks the [shared persistence write coordinator](../architecture/2026-06-18-shared-persistence-write-coordinator.md): with no mutable summary, the coordinator's hook interface needs no `updateSummary` hook and the JSONL-sidecar-vs-SQLite-column durability divergence disappears, so the two backends' write paths converge.
+The removal narrows the public service contract and JSONL on-disk format; the summary was a deliberate forward-looking design, not an accident; and `SessionHeader` stands where the original Agent Note described `SessionMeta`, which is why the summary vanished. It also simplifies the [shared persistence write coordinator](../architecture/2026-06-18-shared-persistence-write-coordinator.md): with no mutable summary, the coordinator needs no `updateSummary` hook, and an out-of-tree provider can reuse the same summary-free orchestration.
 
 ## No migration
 
-This is unreleased software (see [root AGENTS.md](../../../../AGENTS.md) § "Pre-release stance: foundation over blast radius"), so there are no on-disk databases or logs to preserve. SQLite does not migrate a v1 database: the `openDatabase` guard now rejects any non-current on-disk `user_version` (`onDisk !== 0 && onDisk !== SCHEMA_VERSION`) — older *or* newer — so a stale v1 DB is cleanly rejected rather than half-read against the new column set. A fresh database stamps the current version; that is the only path that needs to work.
+The shipped JSONL provider has no mutable summary format or migration path: it reads and writes only `SessionHeader` plus the append-only log. The repository has no first-party SQLite Session provider. The [JSONL-only persistence decision](2026-08-30-jsonl-only-session-persistence.md) owns the compatibility cut for databases written by the removed provider and directs operators to export them with an older build before upgrading.

 ## 决策
 
-彻底删除可变的会话摘要。`SessionSummary` 与 `SessionMeta` 这个名称一并移除；后端存储和返回的元数据仅为 `SessionHeader`。`SessionPersistence.update()` 从抽象服务和所有后端中移除。JSONL 去掉整套伴随文件机制（`writeSidecar`/`readSidecar`/`touchSummary`/`removeSidecars`/`sidecarPath` 以及 load/list 的覆盖逻辑）；SQLite 去掉 `updated_at`/`title`/`first_prompt` 列以及每次追加时的 `updated_at` 更新，其 `SCHEMA_VERSION` 从 `1 → 2`。
+彻底删除可变的会话摘要。`SessionSummary` 与 `SessionMeta` 这个名称均不存在；后端存储和返回的元数据仅为 `SessionHeader`。抽象服务不包含 `SessionPersistence.update()`。交付的 JSONL provider 不包含摘要伴随文件机制（`writeSidecar`/`readSidecar`/`touchSummary`/`removeSidecars`/`sidecarPath` 或 load/list 覆盖逻辑），仓库外 provider 实现相同的无摘要服务约定。
 
 摘要原本要提供的一切，在消费方真正需要时都**可从仅追加日志中派生**（`firstPrompt` = 第一条 `user/message`；近期度 = 最后一个事件的 `time` 或文件 mtime），或者已经存在于不可变 header 中（`createdAt`、`cwd`）。唯一*不可*派生的是用户*手动编辑*的标题，但它从未实现，纯属 YAGNI；如果未来真有功能需要，它可以作为独立的日志事件或 header 字段回归。
 
-这次移除同时收窄两个后端的公开服务约定和磁盘格式；摘要是有意为未来设计的结果，而非意外；如今原 Agent Note 描述 `SessionMeta` 之处已是 `SessionHeader`，这就是摘要消失的原因。它还为[共享持久化写入协调器](../architecture/2026-06-18-shared-persistence-write-coordinator.zh.md)扫清障碍：不再有可变摘要后，协调器的钩子接口不需要 `updateSummary` 钩子，JSONL 伴随文件与 SQLite 列之间的持久性分歧也随之消失，使两个后端的写入路径趋于一致。

 ## 无需迁移
 
-这是未发布的软件（见[根 AGENTS.md](../../../../AGENTS.md)「Pre-release stance: foundation over blast radius」一节），因此没有需要保留的磁盘数据库或日志。SQLite 不迁移 v1 数据库：`openDatabase` 守卫现在拒绝任何非当前版本的磁盘 `user_version`（`onDisk !== 0 && onDisk !== SCHEMA_VERSION`），无论版本更旧*还是*更高，因此陈旧的 v1 数据库会被干净地拒绝，而不会按新的列集合进行不完整读取。新建数据库写入当前版本号；这是唯一需要正常工作的路径。
+交付的 JSONL provider 不存在可变摘要格式或迁移路径：它只读写 `SessionHeader` 与仅追加日志。仓库不包含 first-party SQLite Session provider。[JSONL-only 持久化决策](2026-08-30-jsonl-only-session-persistence.zh.md)负责删除 provider 写入的数据库的兼容性切断，并要求 operator 在升级前先用旧 build 导出数据。

+# Agent Note: JSONL-only first-party Session persistence
+
+Status: implemented
+
+English | [中文](2026-08-30-jsonl-only-session-persistence.zh.md)
+
+## Problem
+
+The product ships and exercises JSONL as its authoritative Session store, while the optional SQLite Session-persistence provider duplicates the same logical service over a second physical format. Every Session contract, event-envelope change, recovery rule, package graph, platform lane, and format transition therefore carries a second implementation and test matrix even though shipped profiles do not select it. Released Session-format migration also needs an exact per-Session source artifact that can be archived before replacement; the single-database provider would require a separate publication design without serving a current deployment.
+
+The SQLite full-text Session-query provider is not an alternative authoritative store. It observes persistence through `ctx.sessionPersistence` and maintains a separate disposable derived index. The generic SQLite domain-KV provider is also independent of Session logs.
+
+## Decision
+
+`@deepseek-ai/dsh-session-persistence-jsonl` is the sole first-party implementation of `ctx.sessionPersistence`. The abstract Service Definition and `PersistenceCoordinator` remain backend-neutral so an out-of-tree provider can implement the same service, but the repository owns and tests one authoritative physical Session format.
+
+The `@deepseek-ai/dsh-session-persistence-sqlite` package, its schema resources, backend-specific tests, configuration surface, and Windows differential lane are absent. Cross-package persistence tests use the real JSONL provider or an owner-local fake. `@deepseek-ai/dsh-session-query-sqlite` remains the optional FTS5 query provider over a separate rebuildable database, and `@deepseek-ai/dsh-storage-sqlite` remains the generic domain-KV provider.
+
+Existing databases written by the removed provider are not opened or migrated by the current build. An operator who needs their contents must use a build that still contains that provider and export the logical Session before upgrading.
+
+## Alternatives considered
+
+- **Keep SQLite as an opt-in differential backend.** Rejected because an unselected production provider still multiplies every durable-format, lifecycle, platform, and migration obligation; contract fakes and the JSONL provider cover the shared service without retaining a second authoritative format.
+- **Keep a read-only SQLite import package.** Rejected because it would preserve the package graph and schema maintenance without a demonstrated deployment need. A recovery tool can be designed later if real retained databases require one.
+- **Use the Session-query SQLite database as persistence.** Rejected because that database is a disposable projection with independent ownership, schema, and rebuild semantics; treating it as authority would merge two unrelated storage roles.
+
+## Consequences
+
+Session persistence has one first-party physical format and one first-party durability path. The migration stack can archive and atomically replace one per-Session JSONL artifact without implementing a parallel database transaction protocol. SQLite search remains available and its integration tests now prove that it observes JSONL rather than sharing an authoritative database.
+
+Removing the provider is a deliberate compatibility cut for its opt-in database files. The change reduces implementation and CI surface but also removes the stronger database/WAL storage option; a future provider needs a current owner, deployment need, complete shared-contract evidence, and its own format-transition policy.

+# Agent Note: JSONL-only first-party Session persistence
+
+Status: implemented
+
+[English](2026-08-30-jsonl-only-session-persistence.md) | 中文
+
+## Problem
+
+产品交付并实际使用 JSONL 作为权威 Session store，而可选的 SQLite Session persistence provider 用第二种物理格式重复实现同一逻辑服务。因此，每项 Session 约定、event envelope 变更、恢复规则、package graph、平台测试与格式迁移都要承担第二套实现和测试矩阵，即使交付 profile 并不选择它。已发布 Session 格式的迁移还需要一份可在替换前归档的精确逐 Session 源产物；单数据库 provider 需要另一套发布设计，却没有服务当前部署。
+
+SQLite 全文 Session-query provider 不是另一种权威 store。它通过 `ctx.sessionPersistence` 观察持久化，并维护独立、可丢弃的派生索引。通用 SQLite domain-KV provider 也与 Session 日志无关。
+
+## Decision
+
+`@deepseek-ai/dsh-session-persistence-jsonl` 是 `ctx.sessionPersistence` 唯一的 first-party 实现。抽象 Service Definition 与 `PersistenceCoordinator` 保持后端无关，使仓库外 provider 仍可实现同一服务，但仓库只拥有并测试一种权威 Session 物理格式。
+
+仓库不再包含 `@deepseek-ai/dsh-session-persistence-sqlite` package、其 schema resource、后端专用测试、配置接口与 Windows differential lane。跨 package 持久化测试使用真实 JSONL provider 或 owner-local fake。`@deepseek-ai/dsh-session-query-sqlite` 继续作为可选 FTS5 query provider 使用独立、可重建的数据库，`@deepseek-ai/dsh-storage-sqlite` 继续作为通用 domain-KV provider。
+
+当前 build 不打开或迁移已删除 provider 写出的现有数据库。需要其中内容的 operator 必须先使用仍包含该 provider 的 build 导出逻辑 Session，再执行升级。
+
+## Alternatives considered
+
+- **保留 SQLite 作为可选 differential backend。** 拒绝，因为未被选择的生产 provider 仍会成倍增加每项 durable format、lifecycle、平台与迁移义务；contract fake 与 JSONL provider 已能覆盖共享服务，无需保留第二种权威格式。
+- **保留只读 SQLite import package。** 拒绝，因为在没有实际部署需要时，它仍会保留 package graph 与 schema 维护成本。若真实保留数据库需要恢复，未来可单独设计 recovery tool。
+- **把 Session-query SQLite 数据库作为 persistence。** 拒绝，因为该数据库是拥有独立 ownership、schema 与重建语义的可丢弃 projection；把它当作权威来源会合并两种无关的存储职责。
+
+## Consequences
+
+Session persistence 只有一种 first-party 物理格式和一条 first-party durability path。迁移 stack 可以归档并原子替换逐 Session JSONL 产物，而无需实现并行的数据库 transaction protocol。SQLite search 保持可用，其 integration test 现在证明它观察 JSONL，而不是共享权威数据库。
+
+删除 provider 是针对其可选数据库文件的明确 compatibility cut。该变更缩小实现与 CI surface，但也移除更强的 database/WAL 存储选项；未来 provider 需要当前 owner、部署需求、完整 shared-contract evidence，以及自身的 format-transition policy。

 ## Alternatives considered
 
 - **Derive the boundary heuristically in `llm-replay`** (the seeded prefix is contiguous parent events ending at the last `turn/end` before the child's first `user/message`). Rejected: a brittle heuristic in the test harness that re-derives a fact the producer already knows. Persisting the boundary at its source (the fork backend) is the "explicit > implicit at package boundaries" rule applied across the persistence boundary — the reader of a child fixture never has to reconstruct where the inheritance ended.
-- **Pin the format version instead of bumping** (the `SESSION_FORMAT_VERSION = 0` "unstable" stance the event log uses). Rejected for the SQLite *table* layout: `SCHEMA_VERSION` is the monotonic bump-and-reject knob (a small enumerable set of revisions worth telling apart), distinct from the event-vocabulary `version`. Adding a column is precisely the breaking table change it versions, so it bumps.
 
 ## Consequences

 The pattern is **compile-time only**. The types vanish at runtime: there is no schema object to validate an incoming value against, parse untrusted input with, or enumerate at runtime. The [session-persistence contract](../../implemented/architecture/2026-06-14-session-persistence.md) exposes two consequences:
 
-1. **Persistence treats `event.data` as opaque JSON.** The JSONL/SQLite backends `JSON.stringify`/`JSON.parse` each event verbatim; the only runtime guard is `isJsonValue` (round-trip serializability — rejects BigInt, functions, cycles, non-finite numbers, …), NOT structural validation. A corrupted-but-still-JSON event datum (wrong field types, missing fields) round-trips silently and is only caught later, if at all, by a consumer's `switch`.

 This raises whether the event vocabulary should move to **Zod** or another runtime-schema library so durable and plugin boundaries have runtime schemas rather than erased types.

The backend interface is therefore designed as **medium owner + data-shape facets**: a session log is an append-only stream, a different shape from KV — forcing them into one set of primitives would deform both, so facets split them (`kv` this phase, `log` at migration) while sharing the medium and its lifecycle.

 Store the latest human-prompt time where a listing already reads — the Session index — so `summarizeCold()` can serve it without opening the log or depending on a cache checkpoint.

That makes it a new `PersistenceBackend` contract element rather than backend-local bookkeeping, with the same event predicate as the attached projection: `user/message` whose `source.kind` is `user`.
 
-The two shipped backends have opposite constraints, and the proposal is deliberately asymmetric about them:
-
-- **SQLite** gets a column on `sessions`, written in the same transaction as `appendBatch`, at the cost of a monotonic `SCHEMA_VERSION` bump.
-- **JSONL cannot host a mutable header field.** The header is line 1, written once during materialization, and the log is opened for append forever after; `jsonl.spec.ts` pins that committed bytes are never rewritten. A per-append header field would violate an asserted durability invariant, not merely complicate the writer. A per-session sidecar file is the shape to compare against leaving JSONL approximate.

 A `Session` is an **append-only log** of typed `SessionEvent`s — the single source of truth. The LLM message history is *derived* from the log (`deriveMessages()`), not stored separately. Every entry carries a monotonic `seq`, a `time`, and a `type`-discriminated `data` payload; surface variants may also list cited earlier events in `sourceEventSeqs` and carry a `surfaceOp`.

-A backend refuses a log it cannot faithfully interpret with `SessionFormatUnsupportedError`, distinct from `SessionPersistenceCorruptionError` because nothing is damaged. A header `version` ahead of `SESSION_FORMAT_VERSION` names the direction ("written by a newer harness — upgrade the harness to open it"); one behind it states that this build ships no upgrade path. After legacy-shape normalization, an event type outside this build's generated vocabulary (`KNOWN_SESSION_EVENT_TYPES`, emitted by `gen-persistence-catalog`) refuses the same way unless the event's envelope carries `ignorable: true` — silently skipping an unrecognized required event could change how the rest of the log must be read. The message appends the raw log path when the backend keeps one artifact per session, so the refused text stays reachable. The JSONL backend refuses a foreign version straight from the raw header line, before validating this format version's header shape or decoding any event row — a structurally different future format still reports the upgrade direction, never "corrupt"; SQLite gates whole-file structure through its own `SCHEMA_VERSION` pragma first. Design rationale and the deferred upgrader chain live in the [session-log-version-mechanism note](../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md).

 ## Summary
 
-The session group makes an agent's conversation durable and reusable outside the live loop: the persistence seam stores the event log and restores it on resume, the checkpoint policy keeps requests, tool side effects, and completed steps durable before the next action, projections serve whole log-derived values to client carriers, titles name each session from its content, and telemetry reports session activity outbound. Pick a persistence backend first — JSONL is the shipped default, SQLite an opt-in single-database backend — then add the checkpoint policy and any projection, title, or telemetry packages the deployment needs. This page maps the group; every package README owns its contract, and `session-query/` is a sibling group whose read/tool surface consumes persistence independently.

-## Summary
-
-`dsh-session-persistence-sqlite` keeps every session's durable history in a single SQLite database: sessions survive restarts, and the deployment's whole history becomes one queryable file you can back up, inspect with SQL, and analyze — instead of one artifact per session. Choosing it changes nothing for the agent loop, the model, or replay, because it serves the same logical `SessionEvent` stream as the JSONL backend; packing, compression, and recovery are storage-internal details. Choose it when a single queryable database fits the deployment; no shipped composition enables it by default. It is a pre-release provider: it rejects database files it does not own instead of migrating them, and its synchronous Node SQLite driver blocks the JavaScript thread during reads and writes. Setup, sizing, and migration guidance come first; the implementation internals live in a collapsible developer section below.

-## Use this package
-
-Mount this provider when a composition needs durable sessions backed by SQLite and accepts a process-local, synchronous database driver. The common path is explicit: load the session service, mount the provider, and give it a database path.
-
-### When to choose it
-
-Choose this backend when a local deployment benefits from one queryable database instead of many per-session files. Choose the JSONL backend when consumers need a per-session artifact: this provider returns `undefined` from `locate(meta)`, supports no raw artifacts, and exposes no per-session file. Account for synchronous SQLite and compression work before adopting it for a high-concurrency service.
-
-### Disk footprint and performance
-
-The packed layout exchanges some SQLite-local latency for a smaller queryable database. The available 501-session comparison measures schema 19 rather than schema 20; that layout used 233.18 MB against the SQLite comparison baseline's 438.31 MB and compressed JSONL's 148.15 MB. Full writes were about 2.3× faster than JSONL and suffix reads remained much faster; complete reads and forks were slightly slower than JSONL. The [persistence latency and page-size decision](../../../.agents/notes/implemented/architecture/2026-08-25-persistence-latency-and-page-size.md) owns the method, complete metrics, and accepted trade-offs.
-
-The disk cost buys a structured, queryable view of session history: external tooling can analyze `sessions` and `events` with SQL, decoding physical rows the way this provider does — the groundwork for features such as built-in full-text search.
-
-### Minimal configuration
-
-Load the session service first, then mount the provider with a database path. Use an absolute path when the location must not depend on the process working directory; relative paths resolve from that directory. `:memory:` is valid for an in-process database whose contents disappear with the process.
-
-```yaml
-- name: '@deepseek-ai/dsh-session'
-- name: '@deepseek-ai/dsh-session-persistence-sqlite'
-  config:
-    path: /absolute/path/to/sessions.db
-```
-
-| Field | Default | Meaning |
-|---|---|---|
-| `path` | required | SQLite database path, or `:memory:` |
-| `journalMode` | `wal` | Durable journal mode: `wal`, `delete`, `truncate`, or `persist` |
-| `busyTimeoutMs` | `5,000` | Maximum synchronous wait for another connection's lock |
-| `preparedSessionCacheSize` | `5` | Cold session preparations retained for resume reuse |
-| `writeBatchMaxDelayMs` | `200` | Fixed live-event coalescing window, in milliseconds |
-
-The generated [configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-session-persistence-sqlite) is the exhaustive source for every accepted field and its JSDoc.
-
-### Migrating existing JSONL sessions
-
-There is no built-in migration tool: the JSONL and SQLite stores are separate, and nothing copies sessions between them. Because both backends implement the same logical contract, you can carry a session over with the persistence API — read on the JSONL side, write on the SQLite side. One backend serves `ctx.sessionPersistence` per composition, so run the two halves as separate runs or processes:
-
-```text
-// Export — run against the JSONL composition, per session id:
-const { meta, events } = await ctx.sessionPersistence.load(id)
-
-// Import — run against the SQLite composition, per exported session:
-await ctx.sessionPersistence.create(meta)
-await ctx.sessionPersistence.append(id, events)
-```
-
-`list()` enumerates the materialized sessions to export. The exported events keep contiguous `seq` values starting at 0, so `append` accepts them as one ordered batch into a fresh session; `load` also commits any needed cold repair on the source first, so the exported log is balanced. Treat the migration as a one-time cutover: verify that the imported sessions load, then switch the composition to the SQLite provider. Continuing to write through the old JSONL root afterwards would let the two stores diverge.
-
-### Startup and safe operation
-
-A fresh database initializes directly at schema version 20 with 64 KiB pages. Existing files are never retuned: databases with any other version, a foreign application identity, an unversioned non-pristine schema, or unexpected schema objects are rejected before any data is exposed or changed. This pre-release provider ships no migration. Every statement and fixed pragma comes from packaged `.sql` resources in `resources/sql/`, and runtime values are bound as SQLite parameters, so package code never assembles query text.
-
-Each connection disables SQLite trusted schemas and memory-mapped I/O, verifies the requested journal mode, and pins `synchronous=FULL` so a resolved append remains durable across an OS crash or power loss. On POSIX, the database parent directory and file must belong to the current user, the parent must not be group/world-writable, and the file must grant no group or world permissions; Windows additionally rejects symbolic links and non-regular files, while ACL restriction stays the deployment's job. Path and ownership failures reject plugin initialization; Node's SQLite driver loads lazily on the first persistence operation. Ordinary `create` stays lazy until the first append, while `ensureMaterialized` writes a session metadata row with no event rows.

-## Understand the implementation
-
-<details>
-<summary>Implementation internals — click to expand</summary>
-
-This section explains the design decisions behind the provider and points at the code that realizes them; the observable behavior is fully covered in [Use this package](#use-this-package).
-
-### Design philosophy
-
-The provider is built on one separation and three commitments:
-
-- **Logical contract, physical format.** Callers always read and write ordinary `SessionEvent[]`; how rows are packed, stored, and compressed is private to this package.
-- **The schema owns the format.** Schema 20 is a frozen physical contract: a database at another version, with a foreign identity, or with unexpected schema objects is rejected, never migrated. Changing the schema, row codec, page size, or dictionary bytes requires a new schema version.
-- **Durability is the default.** Appends run in immediate transactions with `synchronous=FULL`, and a resolved `append()` means the batch is durable. Normal appends are insert-only: earlier event rows are never rewritten.
-- **Efficiency within strict bounds.** Packing and compression keep the database small, but every limit is a hard format bound — at most 1,024 events and 1 MiB of payload per packed row.
-
-The packed-row foundation lives in the [SQLite physical chunk-row decision](../../../.agents/notes/implemented/architecture/2026-08-18-sqlite-physical-chunk-row-compression.md); the current compression, key, and page-size choices live in the [persistence latency and page-size decision](../../../.agents/notes/implemented/architecture/2026-08-25-persistence-latency-and-page-size.md).
-
-### Source map
-
-| File | Role |
-|---|---|
-| [`src/index.ts`](src/index.ts) | Plugin entry: `Config` schema, service registration, coordinator wiring |
-| [`src/store.ts`](src/store.ts) | Storage primitives: transactional append, reads, repair, path and ownership validation |
-| [`src/schema.ts`](src/schema.ts) | Schema ownership: version gate, connection hardening, row decoding |
-| [`src/codec.ts`](src/codec.ts) | Packing: which `assistant/chunk` runs become packed rows, size bounds |
-| [`src/compression.ts`](src/compression.ts) | Physical encoding: dictionary compression, sequence lists, row scan and decode |
-| [`src/sql.ts`](src/sql.ts) + [`resources/sql/`](resources/sql/) | Every SQL statement as a packaged, closed-name resource |
-| [`src/invariant.ts`](src/invariant.ts) | Invariant companion (no runtime invariant; packing is observable only by database round-trip) |
-
-### Database schema
-
-A fresh database contains three strict tables, defined in [`resources/sql/schema.sql`](resources/sql/schema.sql):
-
-| Table | Purpose |
-|---|---|
-| `persistence_state` | One-row store identity |
-| `sessions` | One row per session: header fields plus a monotonic revision |
-| `events` | Physical event rows: one logical event, or one packed run |
-
-The exact columns live in [`resources/sql/schema.sql`](resources/sql/schema.sql). `sessions.id` is an internal integer key while `sessions.session_key` retains the public session id. `events.data` holds text or an independently decodable Zstandard blob; compression uses the schema-owned shared dictionary only when the result is smaller. `events.source_event_seqs` uses tagged delta or run encoding. `events.ignorable` is `0` for a packed chunk run, `1` for a scalar logical event carrying `ignorable: true`, and `NULL` for every other scalar event, so a scalar event whose type matches a physical chunk tag remains unambiguous. Packed rows reuse the `seq` of their first logical event, so under the composite `(session_id, seq)` primary key physical order is logical order.
-
-### Write path
-
-Each append takes an immediate transaction, re-validates schema ownership, checks the stored tail so a stale writer cannot extend the log, packs only the new batch, inserts its rows, bumps the session revision once, and commits. The coordinator coalesces live events for the configured window, so high-frequency streams produce larger packed runs while physical writes stay proportional to newly durable batches.
-
-### Read and recovery
-
-A full read locates the last valid `turn/end` in a reverse pass, then decodes each physical row into its logical events in forward order, rejecting gaps or malformed rows in the committed prefix. A malformed final row is treated as a torn tail: a mutating load may delete it under the write lock and close the log with synthetic closers. Suffix reads (`readFrom`) examine only the physical span that may contain the requested sequence, so they never parse unrelated earlier rows.

-
-<a id="model-experience"></a>
-## Model Experience
-
-### Resumed conversation history
-
-#### What the model sees
-
-Nothing specific to SQLite. Resume restores the same logical events and derived messages as the JSONL backend; physical packed tags never reach prompts, tools, replay, or live `session/event` delivery.
-
-#### Token effect
-
-Zero live-request tokens. Resume pays only for the retained logical history and the current request envelope.
-
-#### KV Cache effect
-
-Physical packing does not mutate request prefixes. Provider cache reuse depends on the reconstructed history, current envelope, and model route exactly as with other persistence backends.
-
-## Known Limitations and Deferred Work
-
-<a id="known-limitations-and-deferred-work"></a>
-
-
-These limits define when the provider is a poor fit or needs special operational care. They are current package constraints, not a general SQLite comparison or a task backlog.
-
-- **Pre-release design with no migration** — schema 20 is an interim SQLite-only design; neither schema stability nor migration support is guaranteed.
-- **Packing depends on batch boundaries** — a compatible run split by the write-behind window or an explicit flush stays split across physical rows; this avoids rewriting prior rows at the cost of a timing-dependent packing ratio.
-- **Synchronous SQLite and compression** — Node's SQLite driver and Zstandard calls block the JavaScript thread.
-- **Busy waits block the event loop** — SQLite waits inside synchronous calls; a competing writer can stall the thread for up to the configured `busyTimeoutMs`.
-- **External SQL readers must decode physical rows** — a packed `events.type` (`text-chunks`, `reasoning-chunks`, `tool-call-chunks`) is not a logical event type; supported consumers read through this provider.
-- **No deletion or historical compaction** — normal appends are insert-only and nothing removes old rows.

-## 概述
-
-`dsh-session-persistence-sqlite` 是 `SessionPersistence` 服务的可选存储后端：它不按会话各留一个文件，而是把所有会话的持久事件日志统一保存在同一个 SQLite 数据库中。它与 JSONL 后端提供完全相同的逻辑 `SessionEvent` 流，因此选择它不会改变 agent loop、模型或回放的任何行为——打包、压缩与恢复都是存储内部细节。仅当单一可查询数据库适合你的部署时才选择它；任何已发布的组合都不会默认启用它。这是预发布提供方：它拒绝而非迁移不属于自己的数据库文件，而且其同步 Node SQLite 驱动会在读写时阻塞 JavaScript 线程。设置、容量评估与迁移指引在前；实现内部细节放在下方可折叠的开发者章节中。

-## 使用本包
-
-当组合需要由 SQLite 支撑的持久会话、且可以接受进程本地的同步数据库驱动时，挂载此提供方。常用路径是显式的：加载会话服务、挂载提供方，然后给出数据库路径。
-
-### 何时选择
-
-当本地部署受益于一个可查询数据库、而非每会话一个独立文件时，选择此后端。当消费方需要按会话产物时，请选择 JSONL 后端：本提供方的 `locate(meta)` 返回 `undefined`，不支持原始产物，也不暴露任何单会话文件。高并发服务在采用前还应考虑同步 SQLite 与压缩工作。
-
-### 磁盘占用与性能
-
-打包布局以部分 SQLite 本地延迟换取更小的可查询数据库。现有的 501 会话对比测量的是 schema 19，而不是 schema 20；该布局占用 233.18 MB，SQLite 对比基线占用 438.31 MB，压缩 JSONL 占用 148.15 MB。全量写入约比 JSONL 快 2.3 倍，后缀读取也仍快得多；完整读取与 fork 则略慢于 JSONL。方法、完整指标与取舍由[持久化延迟与 page size 决策](../../../.agents/notes/implemented/architecture/2026-08-25-persistence-latency-and-page-size.zh.md)记录。
-
-磁盘成本换来的是结构化、可查询的会话历史视图：外部工具可以用 SQL 分析 `sessions` 与 `events`，按本提供方的方式解码物理行——这是内置全文搜索等功能的天然基础。
-
-### 最小配置
-
-先加载会话服务，再用数据库路径挂载提供方。除非位置允许依赖进程工作目录（相对路径从该目录解析），否则请使用绝对路径。`:memory:` 可用于进程内数据库，其内容随进程消失。

-
-### 迁移现有 JSONL 会话
-
-没有内置迁移工具：JSONL 与 SQLite 是两个独立存储，没有任何机制在两者之间复制会话。由于两个后端实现相同的逻辑约定，你可以直接用持久化 API 迁移会话——在 JSONL 侧读取，在 SQLite 侧写入。每个组合只有一个后端服务于 `ctx.sessionPersistence`，因此两步请分两次运行或分两个进程执行：
-
-```text
-// Export — run against the JSONL composition, per session id:
-const { meta, events } = await ctx.sessionPersistence.load(id)
-
-// Import — run against the SQLite composition, per exported session:
-await ctx.sessionPersistence.create(meta)
-await ctx.sessionPersistence.append(id, events)
-```
-
-用 `list()` 枚举已物化的会话。导出的事件 `seq` 从 0 开始连续，因此 `append` 可以一次性按序写入新会话；`load` 会先在源端提交所需的冷修复，导出的日志因此是平衡的。请把迁移当作一次性切换：确认导入的会话可以加载后，再把组合切换到 SQLite 提供方；之后继续写旧 JSONL 根目录会让两个存储分叉。
-
-### 启动与安全运行
-
-全新数据库直接初始化为 schema 版本 20，并使用 64 KiB page。已有文件不会被重新调参：任何其他版本、外来应用标识、无版本的非全新 schema 或意外 schema 对象，都会在任何数据暴露或变更之前被拒绝。本预发布提供方不提供迁移。每条语句和固定 pragma 都来自 `resources/sql/` 下打包的 `.sql` 资源，运行时的值以 SQLite 参数绑定，包代码从不拼装查询文本。
-
-每个连接都会禁用 SQLite trusted schema 与内存映射 I/O、验证所请求的 journal mode，并固定 `synchronous=FULL`，保证成功返回的追加在操作系统崩溃或断电后依然持久。在 POSIX 上，数据库父目录和文件必须属于当前用户，父目录不得允许组或其他用户写入，文件也不得授予任何组或其他用户权限；Windows 还会拒绝符号链接和非普通文件，ACL 限制则由部署方负责。路径与所有权失败会拒绝插件初始化；Node 的 SQLite 驱动在首次持久化操作时才延迟加载。普通 `create` 会保持惰性直到首次 append，而 `ensureMaterialized` 会写入一条没有事件行的会话元数据记录。

-## 理解实现
-
-<details>
-<summary>实现细节——点击展开</summary>
-
-本节解释提供方背后的设计决策，并指出实现它们的代码位置；可观察行为已在[使用本包](#use-this-package)中完整说明。
-
-### 设计理念
-
-本提供方建立在一个分离与三项承诺之上：
-
-- **逻辑约定，物理格式。** 调用方始终读写普通的 `SessionEvent[]`；行如何打包、存储与压缩是本包私有的存储行为。
-- **schema 拥有格式。** Schema 20 是冻结的物理约定：任何其他版本、外来标识或意外 schema 对象的数据库都会被拒绝，绝不迁移。改变 schema、行 codec、page size 或字典字节都需要新的 schema 版本。
-- **持久性是默认值。** 追加在立即事务中以 `synchronous=FULL` 提交，成功返回的 `append()` 意味着该批次已持久。普通追加仅插入：更早的事件行永远不会被重写。
-- **在严格边界内追求效率。** 打包与压缩让数据库保持小巧，但每个上限都是硬性格式边界——每个打包行至多表示 1,024 个事件、1 MiB 载荷。
-
-打包行基础由 [SQLite 物理分片行决策](../../../.agents/notes/implemented/architecture/2026-08-18-sqlite-physical-chunk-row-compression.zh.md)记录；当前压缩、键和 page-size 选择由[持久化延迟与 page size 决策](../../../.agents/notes/implemented/architecture/2026-08-25-persistence-latency-and-page-size.zh.md)记录。
-
-### 源码地图
-
-| 文件 | 职责 |
-|---|---|
-| [`src/index.ts`](src/index.ts) | 插件入口：`Config` schema、服务注册、协调器接线 |
-| [`src/store.ts`](src/store.ts) | 存储原语：事务追加、读取、修复、路径与所有权验证 |
-| [`src/schema.ts`](src/schema.ts) | schema 归属：版本门禁、连接加固、行解码 |
-| [`src/codec.ts`](src/codec.ts) | 打包：哪些 `assistant/chunk` 连续段成为打包行、大小上限 |
-| [`src/compression.ts`](src/compression.ts) | 物理编码：字典压缩、序列列表、行扫描与解码 |
-| [`src/sql.ts`](src/sql.ts) + [`resources/sql/`](resources/sql/) | 所有 SQL 语句均为打包的闭名资源 |
-| [`src/invariant.ts`](src/invariant.ts) | 不变式伴生插件（无运行时不变式；打包只能通过数据库往返观察） |
-
-### 数据库 schema
-
-全新数据库包含三张 STRICT 表，定义于 [`resources/sql/schema.sql`](resources/sql/schema.sql)：
-
-| 表 | 用途 |
-|---|---|
-| `persistence_state` | 单行存储标识 |
-| `sessions` | 每个会话一行：头部字段加单调递增的 revision |
-| `events` | 物理事件行：一个逻辑事件，或一个打包连续段 |
-
-确切的列定义见 [`resources/sql/schema.sql`](resources/sql/schema.sql)。`sessions.id` 是内部整数键，`sessions.session_key` 保留公开会话 id。`events.data` 存放文本或可独立解码的 Zstandard blob；仅在结果更小时才使用 schema 自有的共享字典压缩。`events.source_event_seqs` 使用带 tag 的 delta 或 run 编码。打包分片连续段的 `events.ignorable` 为 `0`，带 `ignorable: true` 的标量逻辑事件为 `1`，其余标量事件为 `NULL`，因此类型与物理分片标签同名的标量事件仍然明确。打包行沿用其首个逻辑事件的 `seq`，因此在复合主键 `(session_id, seq)` 下，物理顺序就是逻辑顺序。
-
-### 写入路径
-
-每次追加都会开启立即事务、重新验证 schema 归属、检查已存尾部以防止陈旧写入方扩展日志、只打包新批次、插入对应行、递增一次会话 revision，然后提交。协调器按配置窗口聚合实时事件，因此高频流会产生更大的打包行，而物理写入量始终与新持久批次成正比。
-
-### 读取与恢复
-
-完整读取先反向定位最后一个有效 `turn/end`，再按正向顺序把每个物理行解码为其逻辑事件，并拒绝已提交前缀中的缺口或格式错误行。格式错误的最后一行被视为撕裂尾部：执行恢复的加载可以在写锁下删除它，并用合成闭合事件关闭日志。后缀读取（`readFrom`）只检查可能包含目标序列的物理跨度，因此永远不会解析无关的更早行。

-- [会话包映射](../README.zh.md)——相邻的持久化、投影、标题与遥测包。
-- [生成配置目录](../../../docs/config-catalog.zh.md#deepseek-aidsh-session-persistence-sqlite)——每个受支持配置字段及其源声明。
-- [SQLite 物理分片行决策](../../../.agents/notes/implemented/architecture/2026-08-18-sqlite-physical-chunk-row-compression.zh.md)——打包布局背后的理由、备选方案与测量。

-## 模型体验
-
-### 恢复的对话历史
-
-#### 模型看到什么
-
-没有 SQLite 专有内容。恢复会还原与 JSONL 后端相同的逻辑事件和派生消息；物理打包标签永远不会进入提示词、工具、回放或实时 `session/event` 投递。
-
-#### Token 影响
-
-实时请求 token 为零。恢复只为保留的逻辑历史和当前请求信封消耗 token。
-
-#### KV Cache 影响
-
-物理打包不会改变请求前缀。提供方缓存复用取决于重建历史、当前信封与模型路由，与其他持久化后端完全相同。
-
-## 已知限制与延期工作
-
-<a id="known-limitations-and-deferred-work"></a>
-
-
-这些限制说明本提供方何时不合适，或何时需要特别的运维注意。它们是当前包约束，不是通用 SQLite 对比或任务积压。
-
-- **预发布设计，无迁移**——schema 20 是临时的 SQLite 专用设计；不保证 schema 稳定性或迁移支持。
-- **打包依赖批次边界**——被写后窗口或显式 flush 拆开的兼容连续段仍分属不同物理行；这避免了重写先前行，代价是打包比例依赖时序。
-- **同步 SQLite 与压缩**——Node 的 SQLite 驱动与 Zstandard 调用会阻塞 JavaScript 线程。
-- **忙等待阻塞事件循环**——SQLite 在同步调用内部等待；竞争写入方最长可让线程停顿配置的 `busyTimeoutMs`。
-- **外部 SQL 读取方必须解码物理行**——打包的 `events.type`（`text-chunks`、`reasoning-chunks`、`tool-call-chunks`）不是逻辑事件类型；受支持的消费方通过本提供方读取。
-- **没有删除或历史压缩**——普通追加仅插入，没有任何机制移除旧行。

 ## Summary
 
-`dsh-session-persistence` stores a session's event log durably, reloads it on resume, and lists stored sessions through one backend-neutral service (`ctx.sessionPersistence`) that every persistence backend implements. The persisted unit is the existing `SessionEvent` log — there is no parallel stored message type — and non-replayable metadata (format version, working directory, lineage, seed boundary) travels separately as `SessionHeader`. Backends own their storage, the service owns the semantics: append-only logs, contiguous sequence numbers, crash recovery that preserves an interrupted turn instead of truncating it, and durable writes that resolve only after the batch is safe. Pick a backend (`session-persistence-jsonl` for per-session files, `session-persistence-sqlite` for one database), mount it, and sessions persist and resume without the loop or the model knowing which backend is underneath.

 ### Choosing a backend
 
-The seam ships two interchangeable backends. Choose [JSONL](../session-persistence-jsonl/README.md) when each session should live in its own on-disk artifact: it stores one append-only `.jsonl.zstd` log per session and returns an absolute artifact path from `locate(meta)`. Choose [SQLite](../session-persistence-sqlite/README.md) when one queryable database fits the deployment: it keeps every session's log in a single database with packed physical rows and returns no per-session artifact. A third-party backend may implement the service directly; the [backend contract](#understand-the-implementation) below is what it must honor.

 ## 概述
 
-`dsh-session-persistence` 通过每个持久化后端都实现的一个后端无关服务（`ctx.sessionPersistence`）持久存储会话的事件日志、在恢复时重新加载并列出已存储会话。持久化单元就是现有 `SessionEvent` 日志——不存在另一套并行的存储消息类型——不可回放的元数据（格式版本、工作目录、血缘、种子边界）作为 `SessionHeader` 单独传输。后端拥有自己的存储，服务拥有语义：仅追加日志、连续序列号、保留中断轮次而非截断的崩溃恢复，以及只在批次安全后才返回的持久写入。选一个后端（按会话存储文件的 `session-persistence-jsonl`，或单库的 `session-persistence-sqlite`），挂载它，会话就会持久化并在恢复时还原，loop 与模型无需知道下面是哪个后端。

 PR 2573

Bring in master through cf6750b10 (including the gate-runner fail-fast
change) and drop the stale fixture reference in the
case-insensitive-path-round-trips note: PR 2573 linked a fixture that PR
3128 had already removed, so every pull request's markdown-links gate
failed on master's own note. The claim stands without naming the deleted
file; verify-md-links now resolves all 2199 files locally.

-## Problem
-
-[`packages/session/session-persistence-jsonl/tests/jsonl.spec.ts`](../../../../packages/session/session-persistence-jsonl/tests/jsonl.spec.ts) proves that a relative `root` is resolved before a session is located. It handed the plugin `relative(process.cwd(), absoluteRoot)` and built its expectation from `resolve(absoluteRoot)` — two different starting points for the same directory.
-
-On a case-insensitive filesystem those starting points can disagree on spelling. `path.relative()` on Windows compares case-insensitively and returns a path with the shared prefix removed, so the casing of that prefix is gone; `path.resolve()` then rebuilds it from `process.cwd()`. When the prefix `tmpdir()` and `process.cwd()` share is spelled with different casing in each, the plugin's resolved root carries the `cwd` spelling while the expectation carries the `tmpdir()` spelling, and `toEqual` compares two strings that name the same file.
-
-A host reaches that state when `tmpdir()` and `process.cwd()` share a path prefix but spell it differently — for example when `TMP` is mapped into the runner work tree under one spelling while the workspace path uses another. Sharing the tree is not enough on its own: if both spell the prefix alike, the round-trip returns the same string. The case fails there and passes everywhere else, which reads as a flake rather than as a fixed disagreement between two spellings.
-
-## Decision
-
-The expectation resolves the same relative root the plugin receives. Both sides pass through one `resolve(cwd, relative)` call, so the case-insensitive round-trip cannot place two spellings on the two sides of the comparison.
-
-This is a test-only change. The platform treats both spellings as the same file, so storage behaviour does not depend on which spelling `resolve()` produces. The string itself stays observable: hook payloads carry it as `transcript_path` and the shell contributor exports it as `DSH_SESSION_JSONL`, so a consumer that compares those strings can still see the difference. Composition fixtures such as [`apps/cli/tests/profiles/headless/tests/fixtures/cli.cordis.yml`](../../../../apps/cli/tests/profiles/headless/tests/fixtures/cli.cordis.yml) set a relative session root — but the plugin resolves whatever it receives before use, so a relative root reaches disk as one spelling rather than two.
-
-The case still asserts what it names: with the plugin's `resolve(config.root)` reduced to `config.root`, so a relative root is no longer resolved, the case fails.
-
-The neighbouring decision about constructing paths with the host `node:path` API lives in [cross-platform test fixtures](2026-07-22-cross-platform-test-fixtures.md); this note covers a different mechanism, the `relative()`/`resolve()` round-trip under a case-insensitive filesystem.
-
-## Alternatives considered
-
-**Compare the two paths case-insensitively.** This keeps the assertion green on the affected runners but accepts a real configuration disagreement as normal, and it would spread to every future path assertion rather than staying in the one case that round-trips through `relative()`.
-
-**Re-register the runners so `workFolder` matches the directory casing.** That repairs the underlying inconsistency, but `.runner` also carries the agent identity, pool, and server URLs, so hand-editing it risks a registration mismatch, and the test would remain fragile for any other host whose temp directory and working directory disagree on casing.
-
-**Normalize through `realpath()` in the expectation.** `realpath()` returns the on-disk casing, which is the `cwd` spelling here, so the case would pass; it also resolves symlinks, which changes what the assertion covers on hosts where the temp directory is a link.
-
-## Consequences
-
-The relative-root case now depends on `resolve()` alone rather than on the two spellings agreeing, so it passes on hosts whose temp directory and working directory disagree on casing. The underlying runner registration is untouched: a `workFolder` whose spelling differs from the directory on disk stays that way, so any future assertion that compares a `tmpdir()`-derived absolute path against a `cwd`-derived one will meet the same disagreement.
-
-The changed case passes, and the whole `session-persistence-jsonl` suite passes at 242 cases. The mechanism was reproduced away from Windows with `path.win32`: `relative()` on two differently-cased spellings of one directory returns a prefix-free relative path, `resolve()` rebuilds it from the `cwd` spelling, and the two absolute strings differ; with both sides spelled alike the same code matches. The regression check above — removing `resolve()` from the plugin — turns the case red while the fixture root and the working directory share a drive letter. Across drives `relative()` returns an absolute path, so both spellings already agree and the check cannot go red; the fixture roots come from `tmpdir()`, so the check only goes red where that path and the working directory share a drive.

-# Agent Note: 测试期望值里的大小写不敏感路径往返

-## 问题
-
-[`packages/session/session-persistence-jsonl/tests/jsonl.spec.ts`](../../../../packages/session/session-persistence-jsonl/tests/jsonl.spec.ts) 有一条用例验证「定位 session 之前会先解析相对 `root`」。它传给插件的是 `relative(process.cwd(), absoluteRoot)`，而期望值由 `resolve(absoluteRoot)` 算出——同一个目录、两个不同的起点。
-
-在大小写不敏感的文件系统上，这两个起点的拼写可能不一致。Windows 的 `path.relative()` 按大小写不敏感比较，返回的是去掉公共前缀之后的相对路径，前缀的大小写信息随之丢失；随后 `path.resolve()` 用 `process.cwd()` 重新拼出前缀。当 `tmpdir()` 与 `process.cwd()` 共有的那段前缀在两者中拼写大小写不同时，插件解析出的 root 带的是 `cwd` 那种拼写，而期望值带的是 `tmpdir()` 那种拼写，于是 `toEqual` 比较的是指向同一个文件的两个字符串。
-
-当 `tmpdir()` 与 `process.cwd()` 共享一段路径前缀、但两者对它的拼写不同时，主机就处在这个状态——例如把 `TMP` 以一种拼写映射进 runner 工作树、而 workspace 路径用另一种拼写。仅仅落在同一目录树内并不够：若两者的前缀拼写相同，往返会得到同一个字符串。该用例只在那里失败、别处都通过，看起来像 flake，实际是两种拼写之间一个固定的分歧。
-
-## 决定
-
-期望值改为解析「插件实际收到的那个相对 root」。两侧都经过同一次 `resolve(cwd, relative)`，大小写不敏感的往返就不可能把两种拼写分别放到比较的两边。
-
-这是只改测试的变更。平台把两种拼写视为同一个文件，所以存储行为不依赖 `resolve()` 产出哪种拼写。字符串本身仍可被观察到：hook 载荷以 `transcript_path` 携带它，shell 贡献者以 `DSH_SESSION_JSONL` 导出它，因此比较这些字符串的消费方仍能看出差异。组合 fixture（测试前置数据）如 [`apps/cli/tests/profiles/headless/tests/fixtures/cli.cordis.yml`](../../../../apps/cli/tests/profiles/headless/tests/fixtures/cli.cordis.yml) 就设置了相对的会话 root——但插件会先解析收到的值再使用，因此相对 root 落盘时只有一种拼写而非两种。
-
-该用例仍然在验证它声称的东西：把插件的 `resolve(config.root)` 降级成 `config.root`（即不再解析相对 root）后，用例转红。
-
-关于「用宿主的 `node:path` API 构造路径」这一相邻决策，归属的 note 是[跨平台测试前置数据](2026-07-22-cross-platform-test-fixtures.zh.md)；本 note 讲的是另一个机制——大小写不敏感文件系统上 `relative()`/`resolve()` 的往返。
-
-## 考虑过的替代方案
-
-**按大小写不敏感的方式比较两个路径。** 这能让受影响的 runner 上变绿，但等于把一个真实的配置分歧当成正常状态接受；而且这种写法会扩散到之后每一条路径断言，而不是留在唯一经由 `relative()` 往返的这一条里。

-**重新注册 runner，让 `workFolder` 与目录大小写一致。** 这修的是底层的不一致，但 `.runner` 里同时存着 runner 的注册身份、pool 与 server URL，手工编辑有造成注册失配的风险；而且只要有别的宿主机的临时目录与工作目录大小写不一致，这条用例仍然是脆的。
-
-**在期望值里用 `realpath()` 归一化。** `realpath()` 返回磁盘上的真实大小写，在这里就是 `cwd` 那种拼写，用例会通过；但它同时会解析符号链接，在临时目录本身是链接的宿主机上会改变该断言覆盖的内容。
-
-## 后果
-
-相对 root 那条用例现在只依赖 `resolve()` 本身，不再依赖两种拼写是否一致，因此在临时目录与工作目录大小写不一致的宿主机上也能通过。runner 注册本身未被改动：注册拼写与磁盘目录名不一致的状态会保持下去，所以今后任何拿 `tmpdir()` 派生的绝对路径去和 `cwd` 派生路径比较的断言，都会遇到同一个分歧。
-
-改动后的用例通过，`session-persistence-jsonl` 整套 242 条用例通过。机制在非 Windows 环境用 `path.win32` 复现过：对同一目录的两种不同大小写拼写调用 `relative()` 会得到不含前缀的相对路径，`resolve()` 用 `cwd` 那种拼写重建，两个绝对字符串因此不同；把两侧拼写改成一致后，同一段代码即匹配。上面那条回归检查——把插件的 `resolve()` 去掉——在 fixture（测试前置数据）根与工作目录同盘符时会让用例转红。跨盘符时 `relative()` 返回绝对路径，两种拼写本就相同，该检查无法转红；本文件的 fixture 根来自 `tmpdir()`，所以只有该路径与工作目录同盘时该检查才会转红。

 A trigger/menu/pick pipeline with zero knowledge of "commands":
 
 - The service holds only the source registry (`InputTriggerSource{trigger: '/'|'@', name, order?, candidates, onPick, matchSpace?, matchEnter?}`; (trigger,name) unique; the optional `order` sorts the roster — lower first, default 0, ties keep registration order — and that sorted roster is both group order and polling order) and `sessionOf(sctx)`. Implementing a match hook IS the declaration of participation in space/enter adjudication; the pipeline polls in roster order, the first non-undefined answer wins, and no claimant means the default sink. matchSpace is synchronous (space fires mid-keystroke; hot cache only); matchEnter is asynchronous (it may await the source's own warmup, and a warmup failure rejects).
-- The controller holds the single authoritative hit (span included; retained for Space after the menu closes), the per-session menu store, the candidate-fetch generation, keyboard arbitration (combobox mode: focus stays in the composer surface, ↑↓/Enter/Escape are intercepted and all pass the IME composition guard, with the single exception Shift+Enter unconditionally going first), and pick orchestration (outcome → self-dispatched bail events). `toggleSource(name, syntheticHit)` is the chrome-launch path: it seeds only that registered source over the caller's composer selection and publishes `launcher = name` until close; ordinary typed tracking clears the launcher and restores the full trigger roster. Both paths render the same MenuView and execute the same `onPick` chain. A `dismiss()` verb backs MenuView's injected `onDismiss` (a pointer down outside both the menu and the surrounding composer card closes the menu; MenuView also localizes group titles through the `slash.menu` locale namespace and clamps its height to the viewport space above the composer via ui-primitives' `useAnchoredMaxHeight`); at each session scope's birth it runs `warm(projection)` once over the source roster — within that scope the projection holds only the stable sessionId, with no published/capability transitions; the scope disposer tears down the controller.
