+# Emit docker-container driver opts that route buildkitd's own registry
+# traffic through the host's egress proxy — but only where that proxy
+# exists and answers. Prints nothing otherwise, so hosted runners and the
+# HK pool keep their default direct route.
+#
+# Why this exists (#16039, #16162): the docker-container driver runs
+# buildkitd in a container that inherits NEITHER the runner process's
+# proxy env NOR the host network namespace. On the mainland release hosts
+# the DNS answer for registry-1.docker.io is poisoned, so buildkitd's
+# direct dial times out while resolving the pinned node:22-slim base —
+# before any application build step. The host-level proxies (dockerd
+# systemd override, runner service env) cannot reach it:
+#   env.*        puts the proxy into buildkitd's own process environment,
+#                which its registry resolver reads;
+#   network=host makes 127.0.0.1:7890 inside the container reach the host
+#                proxy instead of the container's own loopback.
+# Both opts are load-bearing; verified on ecs-qwen-hz1-17/18 where the
+# unopted probe fails with `dial tcp <poisoned IP>:443: i/o timeout` and
+# the opted build resolves the pinned digest for both platforms.
+#
+# The decision is fail-closed: a configured-but-broken proxy must not
+# capture buildkitd, and a host without the marker file must not receive
+# opts pointing at a dead port. The probe log goes to stderr so the next
+# broken build has the measurement in its step log (#16218 precedent).

+`check` takes the options of the later phases and prints them into its plan, so the rows describe the run the operator will make. Each value is quoted for the shell, and a control character in one is spelled as the three-digit octal escapes of its bytes inside `$'...'`, so the plan line carries none to the terminal; bash, ksh and zsh read it back as the value, a digit after it included, which a `\x` escape would let ksh read on into, while `/bin/sh` as dash does not read `$'...'`, so such a line is pasted into one of those. `stop` and `install` repeat all rows above `backup-tools`; `backup` repeats the last two.
 
 The `database` row reads the Flyway scripts from both server jars: the manifest's control-plane component, entries named as Flyway names versioned, undo and repeatable scripts under `db/**/` on the jar's classpath. That is `BOOT-INF/classes/db/**/`, and `db/**/` at the root of each nested jar in `BOOT-INF/lib/`, where the server's modules ship it since the server was split into them. Spring Boot stores a nested jar uncompressed, so the reader reads its directory in place; a compressed one, which Spring Boot would not load, is skipped. A script keeps its path as its name wherever it ships, so one moved from the classes into a module is unchanged. A path shipped twice is one script when the copies match; when they differ, which one Flyway gets depends on the class loader, so the jar is unreadable to the row, which names the two places, `BOOT-INF/classes` or the nested jar, that ship them. A local header's extra field, which archivers add for timestamps or alignment and the central directory need not repeat, is skipped before each entry's data. The `V`, `U` and `R` prefixes are case-sensitive and the `.sql` suffix is not, as in Flyway. A short zip reader follows the central directory and inflates the entries with `zlib`, so releases that predate this change are compared as well. Script contents, not the manifests' version strings, decide the row: a changed script fails even when both manifests name version `1`. Flyway runs a changed repeatable script again, so that is a WARN, while a removed one fails validation. With `outOfOrder` off, as the server keeps it, Flyway also refuses a new versioned script whose version does not sort after the newest one the database ran, comparing the versions part by part. A jar in which the reader finds no script is unreadable rather than unchanged, since no server ships without its schema.
 
@@ -123,7 +123,7 @@ Two cases stay with the operator. The jar can fail to resolve the configuration,
 - **Health endpoint:** Spring Boot's rules for the management port (`ManagementPortType`). Unset or equal to the server's port, it shares the server's listener. A negative one turns the HTTP endpoints off. Any other one opens a listener on `management.server.address`, which binds every interface when unset, under `management.server.base-path`, keeping the server's TLS unless `management.server.ssl` replaces it. `management.endpoints.web.base-path` and the `health` path mapping apply either way, and a blank mapping keeps the name `health`, as Spring Boot ignores it.
 - **Harness:** `qwen.managed-agent.harness.base-url`, the URL the control plane dials, and the preflight's verdict on it: whether its harness row takes the value, untrimmed, as the Harness origin, or `skip` with the Harness disabled, where nothing reads it.
 
-Each phase checks the URLs it dials: both probe the health endpoint, and only `verify --tenant` reads the API, and only when its session row would: the auth mode is `open`, and an `--actor` has a trusted actor header to go in. A phase refuses only over those. A port of 0, picked at start, or a negative one leaves no URL to wait on, so the phase refuses until `--server-url` names one. It refuses as well a URL `fetch` refuses to dial, rather than wait out `--timeout` on probes that cannot be sent: a link-local IPv6 address, which keeps a zone no URL can carry; a port the Fetch standard blocks, such as 6000; and, from `--server-url`, a URL other than `http` or `https`, such as `proxy.test:8443`, or one with a user name or password. A `--server-url` with a query or a fragment is refused too, since the `/actuator/health` and API paths are appended to it and would land in either. `start` waits for the Harness at its URL, so it refuses one that is not `http` or `https`: an opaque value such as `proxy.test:8443` names no host to wait on at all. Past that, it refuses a Harness URL the server's Harness connector would refuse, on the server's own verdict, which its configuration reader passes on: the preflight and the connector read the value untrimmed as `java.net.URI` does and take only an `http` or `https` URL with a host and without user information, a query or a fragment, so user information, a query, a fragment, a host with an underscore, an empty user name or a padded value is refused before the Harness restarts, with no rule of the command's own, and the refusal names the reason where it can. With the Harness disabled nothing reads the value, so nothing more is asked of it. Pooled, the preflight skips its harness row before it reads the value, but each pool member's connector checks it by the same rule, and the pool drops a member whose connector refuses it, so it is judged all the same. When the configuration does not resolve there is no verdict, so `start` itself refuses user information, a query or a fragment, which the server refuses wherever it reads the value. A disabled Harness's value may then be refused for nothing, but letting it through could start a pool that accepts no Session. The preflight judges the rest. A refusal prints a URL with its user information as `***`, whether or not the URL parses; of a value that does not parse, everything up to its last `@` shows as `***`, since a password may hold a `/`, `?` or `#`. A probe that is sent and still fails is named: `start`'s timeout and `verify`'s health row say what the endpoint last answered, such as `HTTP 503, status DOWN` or `self-signed certificate`, with each control character in that text shown as `�` and the text cut at 200 code points, so an endpoint can neither move the cursor, split the row nor scroll the report away. A value that is no string is shown as its JSON, or as `[unprintable]` when it is nested too deep to write out. A Session id or an event type counts only as a string: a Session without a string id fails its row with what came back, and an event type that is no string names no outcome, so the turn row fails. A page whose data is not a list, or that has none, fails its row the same way, and so does a Session id a route cannot carry as one segment (empty, `.` or `..`). Only an event marked `terminal: true` ends the turn, and an event's sequence moves the read on only as a whole number or the digits of one, and only forward. The same holds for the text `verify`'s session and turn rows take from the API, the request a failed row names included; and the cut costs no copy of the text, however long the endpoint's answer. A probe of `start`'s that the deadline cuts short, as it cuts the last one to a millisecond, can time out before any endpoint answers, while it connects or while it reads the body, so it does not replace an earlier answer. One whose own 5-second limit runs out before the deadline does, since the endpoint has stopped answering, and so does any other failure, such as a refused connection. `--server-url` still names the control plane, for example behind a proxy, and the health endpoint is then `<url>/actuator/health`; `verify`, which does not reach the Harness, then resolves the configuration only for `--tenant`. When the configuration does not resolve, in the two cases above, the two phases use the URLs `server.env` names, as the command did before, and print a line that says which: a wrong guess then costs a `--timeout`, where refusing would stop an upgrade that the guess serves.

A `--server-url` with a query or a fragment is refused too, since the `/actuator/health` and API paths are appended to it and would land in either, and so is one with an `@` left after the URL parser has read no user information: that can be the rest of a password that starts with digits, as in `https://svc:12/[email protected]`, which the parser reads as host `svc` and port `12`, so dialling it would reach the wrong host and naming it would print the password. Such an `@` cannot be told from one a path holds, so a path with an `@` is refused too, and is written with `%40` instead. The value is judged as given before the paths are appended: `https:`, which `--server-url "https://$HOST"` leaves with `HOST` unset, is no URL, though `https:/actuator/health` parses, as host `actuator`. `check` judges `--server-url` the same way, since its plan repeats the option. `start` waits for the Harness at its URL, so it refuses one that is not `http` or `https`: an opaque value such as `proxy.test:8443` names no host to wait on at all.

With the Harness disabled nothing reads the value, so nothing more is asked of it. Pooled, the preflight skips its harness row before it reads the value, but each pool member's connector checks it by the same rule, and the pool drops a member whose connector refuses it, so it is judged all the same. When the configuration does not resolve there is no verdict, so `start` takes only a plain `http` or `https` URL, a rule of its own and narrower than the server's: a host name as `java.net.URI` reads one, whose last label starts with a letter unless it is the only one, with or without the final dot of a fully qualified name, a dotted-quad IPv4 address or a bracketed IPv6 one, which may end in an IPv4 address as `::ffff:127.0.0.1` does, an optional port, which may be empty, and a path of the characters a URI path holds, a `%` only as the start of an escape such as `%20`, read untrimmed. Of the forms `java.net.URI` reads as a host, it refuses only those the URL parser `fetch` uses reads as another address: a name of one label that parser reads as a number, of digits, as it reads `1234` as `0.0.4.210`, or of `0x` and hex digits, and an octet with a leading zero, which it reads as octal, as `010.0.0.1` is `8.0.0.1`. A name of one label such as `4harness`, which a container may have, is taken. A disabled Harness's value may then be refused for nothing, but letting it through could start a pool that accepts no Session. The preflight judges the rest, such as whether the Harness answers. A refusal or a report row prints a URL with its user information as `***`, whether or not the URL parses, `start`'s three outcomes and `verify`'s health row included: everything up to its last `@` shows as `***`, since a password may hold a `/`, `?` or `#` that ends the authority early, and one that starts with digits then even parses, as a port, with the rest of it in the path, the query or the fragment (`http://svc:2024#Secret@harness:4170`). A probe that is sent and still fails is named: `start`'s timeout and `verify`'s health row say what the endpoint last answered, such as `HTTP 503, status DOWN` or `self-signed certificate`, with each control character in that text shown as `�` and the text cut at 200 code points, so an endpoint can neither move the cursor, split the row nor scroll the report away. A status that is no string is shown as its JSON, or as `[unprintable]` when it is nested too deep to write out, and an empty one as `""`: `0`, `false` and an empty string are statuses too, and onlLine truncated

+`check` 接受后续阶段的选项，并把它们写进打印的计划，因此这些行描述的正是运维将要执行的那次运行。每个取值都按 shell 规则加引号，其中的控制字符按其字节写成 `$'...'` 里的三位八进制转义，因此计划行不会把控制字符带到终端。bash、ksh 和 zsh 能把它读回原值，紧跟其后的数字也不受影响（若用 `\x` 转义，ksh 会把后面的十六进制数字一并读进去）；作为 dash 的 `/bin/sh` 不认识 `$'...'`，因此这样的行要粘贴到前三种 shell 中运行。`stop` 和 `install` 会重复 `backup-tools` 以上的所有行；`backup` 重复最后两行。
 
 `database` 行从两个服务端 jar 中读取 Flyway 脚本：取 manifest 中的控制面组件，读取 jar 的 classpath 上 `db/**/` 下按 Flyway 规则命名的版本化、撤销和可重复脚本，即 `BOOT-INF/classes/db/**/`，以及 `BOOT-INF/lib/` 中每个嵌套 jar 根目录下的 `db/**/`：服务端拆分为多个模块后，脚本随模块的 jar 发布。Spring Boot 以不压缩的方式存放嵌套 jar，因此读取器直接在原位读取它的目录；压缩过的嵌套 jar Spring Boot 不会加载，因此跳过。无论脚本放在哪里，都以路径作为名称，所以从 classes 挪进某个模块的脚本视为没有变化。同一路径出现两次时，内容相同则视为同一个脚本；内容不同时，Flyway 拿到哪一份取决于类加载器，因此这一行视该 jar 为无法读取，并写明两份分别来自哪里（`BOOT-INF/classes` 或哪个嵌套 jar）。打包工具为时间戳或对齐而在 local header 中加入的 extra field（中央目录不一定重复记录）会在读取每个条目的数据前跳过。与 Flyway 一样，`V`、`U`、`R` 前缀区分大小写，`.sql` 后缀不区分。一个简短的 zip 读取器沿中央目录找到条目，再用 `zlib` 解压，因此早于本改动的版本也能比较。决定这一行结果的是脚本内容，而不是 manifest 中的版本字符串：即使两个 manifest 都写版本 `1`，脚本有变化也会报 FAIL。Flyway 会重新执行有变化的可重复脚本，因此这种情况报 WARN；可重复脚本被删除则会导致校验失败。服务端保持 `outOfOrder` 关闭，此时 Flyway 还会拒绝版本号没有排在数据库执行过的最新脚本之后的新版本化脚本，版本按各段逐一比较。读取器在 jar 中一个脚本都没找到时，视为无法读取而不是没有变化，因为没有哪个服务端会不带 schema 发布。

 - **健康端点：** 遵循 Spring Boot 关于 management 端口的规则（`ManagementPortType`）。未设置或与服务端端口相同时，它与服务端共用监听；为负数时关闭 HTTP 端点；其他值则在 `management.server.address` 上打开独立监听（未设置时绑定所有接口），位于 `management.server.base-path` 之下，并沿用服务端的 TLS，除非 `management.server.ssl` 替换它。两种情况下都应用 `management.endpoints.web.base-path` 和 `health` 的路径映射；路径映射为空白时 Spring Boot 会忽略它，仍使用名称 `health`。
 - **Harness：** `qwen.managed-agent.harness.base-url`，即控制面访问它所用的 URL，以及 preflight 对它的判定：其 harness 行是否把这个未经 trim 的取值当作 Harness origin 接受；Harness 被禁用时判定为 `skip`，此时没有任何地方读取这个值。
 
-每个阶段只检查自己会拨号的 URL：两个阶段都会探测健康端点，只有 `verify --tenant` 会读取 API，而且只在其 session 行确实要读时才读：auth mode 为 `open`，且给了 `--actor` 时服务端配置了可信 actor header。阶段只会因这些 URL 拒绝执行。端口为 0（启动时选取）或负数时没有可等待的 URL，因此该阶段会拒绝执行，直到 `--server-url` 指定一个。`fetch` 会拒绝拨号的 URL，同样会被拒绝，而不是在根本发不出去的探测上等满 `--timeout`：保留了 zone 的 IPv6 链路本地地址（URL 无法携带 zone）、Fetch 标准屏蔽的端口（例如 6000），以及 `--server-url` 给出的非 `http`/`https` URL（例如 `proxy.test:8443`）或带用户名、密码的 URL。带 query 或 fragment 的 `--server-url` 同样会被拒绝，因为 `/actuator/health` 和 API 路径是拼接在它后面的，会落进 query 或 fragment 里。`start` 要在 Harness URL 上等待 Harness，因此会拒绝不是 `http` 或 `https` 的取值：`proxy.test:8443` 这样的不透明取值根本没有可等待的主机。除此之外，对于服务端 Harness 连接器不接受的 Harness URL，`start` 会在重启 Harness 之前拒绝，依据的是服务端配置解析器转达的服务端自身判定：preflight 和连接器都按 `java.net.URI` 的方式读取未经 trim 的取值，只接受带主机名、且不带用户信息、query 或 fragment 的 `http` 或 `https` URL，因此带用户信息、query、fragment、带下划线的主机名、空用户名或带首尾空白的取值都会被拒绝，命令本身不另立规则；能说明具体原因时，拒绝提示会写明。Harness 被禁用时没有任何地方读取这个值，因此不再对它提其他要求。启用 pool 时，preflight 的 harness 行在读取该值之前就跳过，但每个 pool 成员的连接器都按同一规则检查它，连接器拒绝的成员会被 pool 丢弃，因此照样要判定。无法解析配置时没有判定，`start` 会自行拒绝带用户信息、query 或 fragment 的取值，因为只要服务端读取这个值就会拒绝它们。这样，被禁用的 Harness 的取值可能被白白拒绝，但若放行，可能启动一个不接收任何 Session 的 pool。其余情况由 preflight 判定。拒绝提示打印 URL 时，无论它能否解析，用户信息都显示为 `***`；对无法解析的取值，最后一个 `@` 之前的内容全部显示为 `***`，因为密码中可能含有 `/`、`?` 或 `#`。探测发出后仍失败时，会说明原因：`start` 的超时提示和 `verify` 的 health 行给出健康端点最后一次的应答，例如 `HTTP 503, status DOWN` 或 `self-signed certificate`；应答文本中的控制字符显示为 `�`，文本在 200 个码点处截断，因此端点既无法移动光标、拆开一行，也无法把报告刷出屏幕。不是字符串的值显示为它的 JSON；嵌套太深无法写出时显示为 `[unprintable]`。Session id 和事件类型只认字符串：Session 没有字符串 id 时，该行判失败并写出实际返回的值；事件类型不是字符串时不代表任何结果，turn 行判失败。页面的 data 不是列表或缺失时，对应的行同样判失败；Session id 无法作为路由中的单独一段时（空串、`.` 或 `..`）也是如此。只有标记为 `terminal: true` 的事件才会结束 turn；事件序号只有是整数或整数的数字串时才推进读取位置，而且只向前推进。`verify` 的 session 和 turn 行中来自 API 的文本同样如此，失败行中写出的请求也不例外；而且无论端点的应答多长，截断都不会复制一份全文。`start` 的探测被截止时间截短时（最后一次只剩 1 毫秒），无论是在连接时还是在读取响应体时，都可能在端点来得及应答之前超时，因此不会覆盖之前的应答。在截止时间之前就用满自身 5 秒上限而超时的探测会覆盖，因为这说明端点已不再应答；其他失败（例如连接被拒）也会覆盖。`--server-url` 仍可指定控制面的地址，例如位于代理之后，此时健康端点为 `<url>/actuator/health`；`verify` 不访问 Harness，这时只为 `--tenant` 解析配置。无法解析配置时（即上文的两种情况），两个阶段与以前一样使用 `server.env` 中给出的 URL，并打印一行说明用了哪些：猜错的代价是等满一次 `--timeout`，而拒绝执行会挡住猜对时本可以完成的升级。
+每个阶段只检查自己会拨号的 URL：两个阶段都会探测健康端点，只有 `verify --tenant` 会读取 API，而且只在其 session 行确实要读时才读：auth mode 为 `open`，且给了 `--actor` 时服务端配置了可信 actor header。阶段只会因这些 URL 拒绝执行。端口为 0（启动时选取）或负数时没有可等待的 URL，因此该阶段会拒绝执行，直到 `--server-url` 指定一个。`fetch` 会拒绝拨号的 URL，同样会被拒绝，而不是在根本发不出去的探测上等满 `--timeout`：保留了 zone 的 IPv6 链路本地地址（URL 无法携带 zone）、Fetch 标准屏蔽的端口（例如 6000），以及 `--server-url` 给出的非 `http`/`https` URL（例如 `proxy.test:8443`）或带用户名、密码的 URL。带 query 或 fragment 的 `--server-url` 同样会被拒绝，因为 `/actuator/health` 和 API 路径是拼接在它后面的，会落进 query 或 fragment 里；URL 解析器读不出用户信息、却仍带有 `@` 的 `--server-url` 也会被拒绝：它可能是以数字开头的密码的剩余部分，例如 `https://svc:12/[email protected]` 会被解析成主机 `svc`、端口 `12`，拨号会连到错误的主机，打印又会泄露密码。这样的 `@` 与路径里的 `@` 无法区分，因此路径带 `@` 的取值同样会被拒绝，应改写为 `%40`。取值在拼接路径之前先按原样判定：`--server-url "https://$HOST"` 在 `HOST` 未设置时留下的 `https:` 不是 URL，尽管 `https:/actuator/health` 能解析成主机 `actuator`。`check` 以同样的方式判定 `--server-url`，因为它打印的计划会重复这个选项。`start` 要在 Harness URL 上等待 Harness，因此会拒绝不是 `http` 或 `https` 的取值：`proxy.test:8443` 这样的不透明取值根本没有可等待的主机。除此之外，对于服务端 Harness 连接器不接受的 Harness URL，`start` 会在重启 Harness 之前拒绝，依据的是服务端配置解析器转达的服务端自身判定：preflight 和连接器都按 `java.net.URI` 的方式读取未经 trim 的取值，只接受带主机名、且不带用户信息、query 或 fragment 的 `http` 或 `https` URL，因此带用户信息、query、fragment、带下划线的主机名、空用户名或带首尾空白的取值都会在重启 Harness 之前被拒绝；只有当取值本身显示出一个服务端同样会给出的原因时，拒绝提示才会写明：用户名或密码、query 或 fragment，或 authority 中的 `@`（`java.net.URI` 在 `//` 之后读取 authority，直到 `/`、`?` 或 `#`）。Harness 被禁用时没有任何地方读取这个值，因此不再对它提其他要求。启用 pool 时，preflight 的 harness 行在读取该值之前就跳过，但每个 pool 成员的连接器都按同一规则检查它，连接器拒绝的成员会被 pool 丢弃，因此照样要判定。无法解析配置时没有判定，`start` 只接受朴素的 `http` 或 `https` URL，这是命令自己的规则，比服务端的更窄：`java.net.URI` 认可的主机名（最后一个 label 以字母开头，只有一个 label 时除外；完整域名末尾的点可有可无）、点分四段的 IPv4 地址，或带方括号的 IPv6 地址（可以像 `::ffff:127.0.0.1` 那样以 IPv4 地址结尾），可选端口（可以为空），以及只含 URI 路径允许字符的路径，其中 `%` 只能作为 `%20` 这类转义的开头，按未经 trim 的原样读取。在 `java.net.URI` 认作主机的写法中，它只拒绝 `fetch` 所用的 URL 解析器会读成别的地址的写法：该解析器读成数字的单个 label，即全为数字（例如 `1234` 读成 `0.0.4.210`）或 `0x` 加十六进制数字；以及带前导零的 IPv4 段，会被读成八进制（例如 `010.0.0.1` 读成 `8.0.0.1`）。`4harness` 这类以数字开头的单 label 名字（容器可能使用）会被接受。这样，被禁用的 Harness 的取值可能被白白拒绝，但若放行，可能启动一个不接收任何 Session 的 pool。其余情况由 preflight 判定，例如 Harness 是否应答。拒绝提示或报告行打印 URL 时，无论它能否解析，用户信息都显示为 `***`，`start` 的三种结果和 `verify` 的 health 行也不例外：最后一个 `@` 之前的内容全部显示为 `***`，因为密码中可能含有 `/`、`?` 或 `#`，使 authority 提前结束；以数字开头的这类密码甚至能解析成功，被读成端口，其余部分落进路径、query 或 fragment（`http://svc:2024#Secret@harness:4170`）。探测发出后仍失败时，会说明原因：`start` 的超时提示和 `verify` 的 health 行给出健康端点最后一次的应答，例如 `HTTP 503, status DOWN` 或 `self-signed certificate`；应答文本中的控制字符显示为 `�`，文本在 200 个码点处截断，因此端点既无法移动光标、拆开一行，也无法把报告刷出屏幕。不是字符串的 status 显示为它Line truncated

+# Web Shell waiting card
+
+[English](2026-11-01-web-shell-waiting-minigame.md) | [简体中文](2026-11-01-web-shell-waiting-minigame.zh-CN.md)
+
+Status: implemented; runtime release verification pending.
+
+## Problem
+
+A streaming prompt can take minutes. The composer only shows a spinner,
+elapsed time, token count, and a rotating loading phrase. Users have nothing
+playful or interactive to do while they wait, and the Web Shell has no waiting
+experience beyond passive status text.
+
+## Current state
+
+`StreamingStatus` renders above the main `ChatEditor` whenever
+`streamingState !== 'idle'` or the daemon reports an active prompt. The Web
+Shell owns the streaming state, transcript messages, token usage, composer
+layout, i18n, theme tokens, and local storage patterns. Split panes and
+side-task panes render their own `ChatPane` composers and keep a compact status
+line.
+
+## Goals
+
+- Add a compact heatmap button at the end of the main composer's streaming
+  status while a prompt is running.
+- Open a waiting card above the status row:
+  - the task's Q&A activity heatmap by default, with hover details and
+    click-to-locate;
+  - an `Activity` / `Usage` switch, where `Usage` shows task token consumption
+    instead of a credits balance;
+  - an optional, configuration-gated game entry on a random cold day.
+- Keep the activity and usage views available without configuration; the game
+  entry stays hidden unless it is explicitly enabled.
+- Keep keyboard input and the composer usable; never hijack typing.
+- Keep the feature local to the browser: no backend, daemon, transcript,
+  telemetry, or model changes.
+
+## Non-goals
+
+- No welcome-page game, leaderboard, multiplayer, or cross-device scores.
+- No game in split panes, side-task panes, or on coarse-pointer devices.
+- No mobile touch controls in this change.
+
+## Proposed solution
+
+`WaitingMinigameButton` renders at the end of the `StreamingStatus` row while a
+prompt is active. Clicking it mounts `WaitingMinigame` above the row:
+
+1. The card opens on `Activity`: a fixed 44-week calendar (44 columns × 7
+   rows). Columns are Monday-to-Sunday weeks and every cell is one local day.
+   The calendar ends with the current week; days after today are empty
+   placeholders. Cell color shows that day's Q&A count, month labels sit below
+   the grid, hovering a cell shows its date and count, and clicking a populated
+   day scrolls the transcript to the first Q&A of that day and highlights the
+   message.
+2. When the game entry is enabled, a white square with a dark gamepad icon
+   appears after five seconds on a randomly chosen cold day. Clicking it starts
+   either horizontal Tetris or Snake at random; there is no picker or switch
+   control. Without the configuration, the gamepad mark and all game controls stay
+   absent and the card remains an activity/usage readout.
+3. The `Usage` tab shows total tokens, input, output, cached, and context
+   used/limit for the task. It replaces the credits view from the reference
+   design.
+4. A `QWEN CODE` pixel intro plays before the game. For Tetris, the letters
+   appear cell by cell, then the blocks fly to the right edge and settle into
+   the random start cluster that the game begins with. For Snake, the letters
+   stay still and the game starts without moving blocks. Both games use the
+   same 44×7 board. Tetris clears columns for 50 points; Snake eats an apple
+   emoji and scores one point per apple. Both pause with Space and close with
+   Escape.
+5. When the prompt ends, the button and card unmount. Best scores and the sound
+   preference stay in `localStorage`.
+6. Inputs, textareas, contenteditable editors, and textboxes keep their
+   keyboard behavior. The card ignores keys targeted at those elements.
+
+The activity and token summaries live in framework-free
+`utils/waitingActivity.ts`; the two games live in `utils/waitingMinigame.ts`
+and `utils/waitingSnake.ts`, so engines can be tested without React, jsdom, or
+timers.
+
+## Design decisions
+
+- **Inline trigger instead of a banner.** A full-width strip competed with the
+  conversation. A single icon at the end of the status line costs no extra row;
+  the card only appears on demand.
+- **Activity first.** The expanded card starts with the task's own daily
+  calendar rather than the game. It gives the card a useful reading state and
+  makes the gamepad mark an intentional, optional game entry.
+- **Activity primary, game opt-in.** The card's product purpose is to surface
+  the task's Q&A activity by time; the game is a waiting-time extra. Keeping
+  the game behind configuration avoids shipping an unexpected interactive
+  surface to every user.
+- **Hover details and jump-to-message.** Each bucket exposes its time range and
+  Q&A count, and a bucket that contains messages becomes a navigation target.
+  The anchor prefers the first user question so the transcript lands at the
+  start of the exchange.
+- **Delayed entry on a cold cell.** Hiding the gamepad mark for five seconds keeps
+  the heatmap useful during the first moments of a turn. Placing it on the
+  coldest day keeps the busiest dates unobstructed.
+- **Fixed daily cells.** Every cell is one calendar day instead of a bucket
+  stretched from the task span. Time semantics stay stable, a short task simply
+  lights up today's cell, and the month axis matches the reference calendar.
+- **Random game instead of a picker.** A single click starts one of the two
+  games; removing the picker and switch keeps the waiting card compact.
+- **Different intros for the two games.** Tetris uses the intro blocks as its
+  starting pile, so the blocks fly to the right edge. Snake has no pile to
+  inherit, so its intro stays still and yields directly to the game.
+- **Tokens instead of credits.** The task already owns token and context data;
+  a credits balance would introduce a second accounting surface.
+- **Flow layout instead of an overlay.** Adding a normal footer child avoids
+  DOM measurement, clipping, and z-index coupling with the editor. The
+  trade-off is a transient transcript resize when opening the card.
+- **Stable card frame.** The header, tab row, body and footer are reserved in
+  every view, and the body keeps the calendar height. Switching between
+  activity, usage, intro and game does not resize the card or move the
+  composer.
+- **Main composer only.** The App composer is the single-session surface.
+  Split and side-task panes are separate `ChatPane` instances and do not
+  render the card.
+- **Coarse pointer hidden.** `isCoarsePointerDevice()` keeps the card out of
+  phones and tablets; a narrow desktop window still gets the compact grid.
+- **Immutable engines.** Each tick returns a new state object. React state
+  updates stay predictable, and render grids can be derived without mutating
+  boards.
+- **Best-effort audio.** A Web Audio context is created inside the start
+  gesture. Missing or blocked audio never blocks a game.
+
+## Constraints
+
+- No new dependencies.
+- No changes to daemon routes, prompts, transcript blocks, or host props.
+- Approval and question overlays render above the composer. The card stays
+  inside the composer footer below them.
+
+## Configuration
+
+The activity and usage views are always available. The game entry is off by
+default and can be enabled with any of:
+
+- `?waitingGames=1` on the Web Shell URL; `?waitingGames=0` forces it off even
+  when a stored or host flag enables it.
+- `localStorage['qwen-code-web-shell-waiting-games'] = '1'`.
+- A host-injected `window.__QWEN_CODE_WAITING_GAMES__ = true`.
+
+The local harness exposes the same switch as `Games: off/on`. Game screenshots
+in this document were captured with the entry enabled.
+
+## Screenshots
+
+The activity, usage and dark-theme screenshots use the local harness sample
+data with the game entry off. The intro and game frames use the Chromium E2E
+(`client/e2e/waiting-minigame.spec.ts`) with the game entry enabled.

+
+## Validation plan
+
+- Activity/token tests: fixed calendar, day grouping, future placeholders,
+  message anchors, usage sums and fallback.
+- Tetris tests: spawn, gravity, movement bounds, rotation kicks, locking,
+  column clears, score, speed floor, game over, pause, render grid, and the
+  prefilled start cluster.
+- Snake tests: spawn, movement, turn queue and reversals, food and score, wall
+  and body collision, pause/restart, render grid, and the slower opening speed.
+- Component tests: closed by default, activity first, day hover details, day
+  click, hidden game entry by default, configured game entry after five
+  seconds, intro timings, Tetris flight and landing, static Snake intro,
+  pause/resume, Escape, tab-hidden pause, trigger state.
+- Configuration tests: default off, storage flag, URL flag and override,
+  host-injected global.
+- App regression suite (`client/App.test.tsx`) for the composer and streaming
+  status.
+- Chromium E2E: trigger → heatmap → hover details → game-off default →
+  configured game entry → QWEN CODE intro → Tetris flight/landing → pause;
+  Snake intro without movement; dark theme and Chinese copy.
+- Local harness: `client/e2e/waiting-minigame-harness.html` with synthetic
+  activity/token data, selectable entry delay, and theme/language switches.
+
+## Acceptance criteria
+
+- The trigger appears only while a prompt is active; the card closes with the
+  turn.
+- The card opens on a fixed 44-week daily calendar, shows day details on
+  hover, and locates a clicked day in the transcript.
+- The gamepad mark appears after five seconds on a cold day when the game entry
+  is configured; both games run in the same 44×7 board.
+- The game entry and game controls are hidden by default and only appear with
+  the configuration enabled.
+- The Tetris intro blocks form the right-side start cluster; the Snake intro
+  does not move its blocks.
+- The game/card does not break composer input and never steals editor keys.
+- Split panes, side-task panes, and coarse-pointer devices do not show the
+  card.
+- `localStorage` keeps the best scores and sound preference.
+
+## Open questions
+
+- Should a later change expose the card on the welcome page or on touch
+  devices with on-screen controls?
+- Should the host be able to disable the card through customization?

+# Web Shell 等待卡片
+
+[English](2026-11-01-web-shell-waiting-minigame.md) | [简体中文](2026-11-01-web-shell-waiting-minigame.zh-CN.md)
+
+状态：已实现；运行时发布验收待完成。
+
+## 问题
+
+一次流式提问可能持续数分钟。输入框上只显示转圈、耗时、token 数和轮换的加载文案，等待期间没有可交互的内容。Web Shell 目前只有被动的等待状态。
+
+## 现状
+
+`StreamingStatus` 在 `streamingState !== 'idle'` 或 daemon 报告存在活动 prompt 时显示在主 `ChatEditor` 上方。Web Shell 已掌握真实流式态、转录消息、Token 用量、输入框布局、i18n、主题 token 和本地存储模式。分屏和侧边任务使用各自的 `ChatPane` 输入框，并保留紧凑状态行。
+
+## 目标
+
+- 提问运行期间，在主输入框的流式状态行末尾显示一个紧凑的热力图按钮。
+- 点击后在状态行上方打开等待卡片：
+  - 默认显示本任务的按天问答活动日历，支持悬停详情和点击定位；
+  - 可在 `热力图` / `消耗` 之间切换，`消耗` 显示本任务 Token，而不是 Credits 余额；
+  - 游戏入口是可配置的可选项，默认不显示。
+- 活动和 Token 视图无需配置即可使用；只有显式开启配置后才展示游戏入口。
+- 保持输入框和键盘可用，绝不抢占用户输入。
+- 功能只发生在浏览器本地：不写后端、daemon、转录、埋点或模型请求。
+
+## 非目标
+
+- 不做欢迎页小游戏、排行榜、多人对战或跨设备分数。
+- 分屏 pane、侧边任务 pane 和粗指针设备不展示卡片。
+- 本次不做手机触控操作。
+
+## 方案
+
+`WaitingMinigameButton` 在 prompt 活动期间渲染于 `StreamingStatus` 状态行末尾。点击后，`WaitingMinigame` 卡片挂载到状态行上方：
+
+1. 卡片默认打开 `热力图`：固定 44 周日历（44 列 × 7 行）。列是周一到周日的自然周，每个方格是一天；日历结束于当前周，今天之后的格子留空。颜色表示当天的问答数量，月份标签在日历下方；悬停方格显示日期和数量，点击有问答的日期会滚动到当天第一条问答并高亮消息。
+2. 配置开启游戏入口后，白底深色游戏手柄图标的方块会在 5 秒后出现在随机一个冷门日期上。点击后随机开始横向俄罗斯方块或贪吃蛇，不提供游戏选择或换游戏。未开启配置时游戏手柄图标和所有游戏控件都不显示，卡片只展示活动和 Token。
+3. `消耗` 页显示本任务总 Token、输入、输出、缓存以及上下文占用/上限，替代参考设计里的 Credits 视图。
+4. 游戏开始前播放 `QWEN CODE` 像素入场。俄罗斯方块会把文字方块飞到右侧，落成随机开局堆；贪吃蛇没有开局堆，文字保持不动后直接进入游戏。两个游戏共用 44×7 棋盘。俄罗斯方块满列 +50；贪吃蛇吃苹果 emoji，每个苹果 +1；两者都支持空格暂停、Esc 关闭。
+5. 回复结束时按钮和卡片一起卸载。最高分和音效偏好保存在 `localStorage`。
+6. 输入框、文本域、contenteditable 编辑器和 textbox 保留原有键盘行为；卡片忽略发往这些元素的按键。
+
+活动与 Token 摘要放在与框架无关的 `utils/waitingActivity.ts`；两个游戏分别放在 `utils/waitingMinigame.ts` 和 `utils/waitingSnake.ts`，引擎测试不依赖 React、jsdom 或计时器。
+
+## 设计决策
+
+- **使用行内按钮而非横幅。** 输入框上方的整条横幅会和对话内容争夺垂直空间；状态行末尾的单个图标按钮不额外占一行，卡片只在需要时出现。
+- **热力图优先。** 展开卡片先展示本任务的按天活动日历，而不是直接开始游戏。它给卡片一个有用的阅读状态，也让游戏手柄图标成为明确的、可选的游戏入口。
+- **活动为主，游戏可配置。** 卡片的产品目的是透出任务按时间的问答热度；游戏只是等待时的附加项。把游戏放在配置后面，避免默认向所有用户暴露一个意外的交互面。
+- **悬停详情与点击定位。** 每个时间桶展示时间范围和问答条数；包含消息的桶可以点击定位。锚点优先选择第一条用户提问，让对话滚动到问答开始的位置。
+- **延迟出现并放在冷门格子。** 游戏手柄图标前 5 秒不出现，让热力图在回合刚开始时保持干净；放在最冷门的日期上可以避免遮挡最活跃的格子。

 - **Detection.** A sweep compares a fresh view — or the slim listing's state for a merged or closed PR — with the PR's watch file and writes the new observation, the updated `ciFired` and any detected transition to it in one atomic write under the PR's lock. An observation is stamped with the time it started, and one that started before the file's `observedAt` is discarded — neither compared nor written — so a slow view can never roll the baseline back. Because the file is the only baseline, observation can stay per workspace while detection and delivery are PR-scoped: a binder whose workspace is unreachable, untrusted or retired this tick holds no copy that could lag behind or detect a transition a second time, and when it becomes reachable again it simply becomes a recipient candidate.
 - **Target.** One recipient per PR across the whole daemon — one per role group with role-aware actions, below — never one per workspace. The recipient is resolved lazily, at delivery time, and only for keys not yet admitted (§5): among the eligible sessions bound to the PR in the workspaces the bindings scan covers (trusted workspaces and the primary), the most recently active one (transcript mtime, refined by the bridge's live activity), the channel's legacy rule, dispatched through that session's owning runtime. On a partial scan the drain keeps, for each session the scan does not list, its row from the last scan that did list it — complete or partial, as the adapter rebuilds its retained bindings from every snapshot — bounded as the adapter's retention is (`MAX_PARTIAL_RETAINED`, oldest dropped first), and drops a retained row once a complete scan omits the session, so a newer binder that is briefly unreachable still competes by recency — the adapter retains unlisted sessions for the same reason, so that a partial answer listing only an older session cannot displace the newer one — and when such a retained session wins, the entry stays pending until it can be reached. This applies within each role group with role-aware actions. A recipient archived or outranked between detection and drain loses nothing: the drain resolves the next one. Archived sessions, channel-owned sessions (`sourceType: 'channel'`) and machine-owned hidden-catalog sessions (`isHiddenCatalogSource`: `agent-host`, `agent`) are never targets, and a workspace that is no longer registered, no longer covered by the scan (untrusted and not primary), or whose runtime generation is retired (`assertGenerationOpen()`) is skipped with a log line, re-resolved immediately before dispatch. Two registered workspaces for one repository, each with a session following the same PR, therefore produce one delivery, not two, with or without a crash in between.
-- **Role-aware actions.** With `sessionPrWatch.actions` set, delivery follows the channel's role-aware mode (#16258) restricted to the four transitions. Keys are `<type>`, `<role>:<type>`, `<role>:default` and `default`, with `<role>` one of `review`, `verify`, `fix`; values are instruction templates, non-empty, trimmed and at most 2,000 code points as in the channel, with the channel's variables (`%repo%`, `%pr%`, `%url%`, `%title%`, `%event%`, `%sender%`, `%role%`): `%repo%` is `owner/repo` as the group winner's bound URL spells it at delivery time, keeping its case as the channel's does, `%pr%` is its number, `%url%` is that URL's origin with `www.` stripped and its port kept, followed by `/<owner/repo>/pull/<number>` (the watch file's key, lowercased and without a port, is not used for display), `%title%` comes from the last view, and `%sender%` is `GitHub`, as for the channel's watch events; `%title%` and `%sender%` are sanitised and capped at 200 code points with a visible marker, as in the channel. Each role group — review, verify, fix and untyped, by the binding's `role` in the sidecar — resolves `<role>:<type>` → `<role>:default` → `<type>` → `default`, untyped bindings resolve only the bare chain, and no match skips that group for the transition. A group is matched when its chain resolves a template; a matched group with no eligible binder on a complete scan is skipped for the transition, and on a partial scan it waits (Scan completeness). Each matched group has its own winner (the most recently active binder with that role), its own admission under the group-suffixed key, and a prompt carrying the rendered instruction in the channel's labelled trusted-instruction block, under the channel's untrusted-data notice that extends to the GitHub-derived values substituted into it; at most four deliveries per transition. Each group's admission records the group in the entry's `served` list and the group-suffixed key in `delivered`, in one write, and a drain skips a served group, so a group is never served twice while another group's winner is still dormant; the entry leaves `pending` once every matched group is served. Without `actions`, delivery is the single winner and the generic prompt. The key and template validation, the chain resolution and the rendering are not reimplemented: PR A moves the channel's own code for them out of `GithubAdapter.ts` into `@qwen-code/channel-base`, with the event vocabulary and the comment-lane class as parameters and the renderer taking the variable values instead of a channel envelope — the channel passes `watch:<type>`, its notification reasons and, for comment events, the `comment` lane (so `<role>:comment` and `comment` still catch them), and derives the values from its envelope as today; the daemon passes the four bare transition types, no lane and the values above, so `fix:ci_failure` is a valid key here and a notification reason such as `mention` is not — and the adapter keeps using it for comment events and, until PR B, for watch events, so `%%` renders a literal `%` and an unknown `%foo%` stays literal exactly as in the channel. `%event%` renders the bare transition type (`ci_failure`); under the alias (§7) a template written for the channel, where it rendered `watch:ci_failure`, therefore renders the bare type.

The move fixes two quirks of the channel's renderer: a `%name%` naming an `Object.prototype` member, such as `%constructor%`, rendered that member instead of staying literal, and only `%title%` and `%sender%` were sanitised. `%event%` renders the bare transition type (`ci_failure`); under the alias (§7) a template written for the channel, where it rendered `watch:ci_failure`, therefore renders the bare type.
 - **Scan completeness.** The sweep calls the scan in-process for its view set and its recipients. On this tree `partial` means something could not be read — a registered workspace with no runtime, a chats directory that cannot be listed, an unreadable sidecar or transcript, a live session list that cannot be fetched — never a page boundary: the scan is one directory listing per workspace (#16241). A workspace the scan cannot enumerate contributes no views and no newly listed recipients this tick — its sessions' retained rows still compete (Target) — and nothing else depends on it, because no watch state lives in its sidecars; `partial` defers every negative decision: deleting a watch file (§2; under partial scans only the 7-day `lastBoundAt` rule applies), skipping a role group for lack of an eligible binder, and dropping a transition because no candidate remains (below) are decided only on a complete scan; on a partial one the entry stays in `pending` for a later drain, within the 16-entry cap and the 7-day age limit (§5). The slim-listing `state` refresh is unaffected.
 - **Archive and restore.** Archiving a session changes nothing in the PR's watch file: the session only leaves the recipient candidates, and its sidecar keeps its top-level `state`, still refreshed. A session restored from the archive rejoins them. If another binder kept the PR watched, the file is current and the restored session receives transitions from then on; if nobody followed the PR, its file was deleted (§2) and the PR initialises silently, so what changed while the session was archived is not replayed into it — the restore is a user action, and the refreshed top-level `state` already shows it in the sidebar. A restore within 7 days of the last binder leaving, while scans stay partial, resumes from the last observation and delivers a transition in the gap once.
 - **Mechanism.** PR A extracts the prompt admission from the route handler into a function the route and the refresh both call — the idempotency ring, the classification and the backfill skip move with it, the skip keyed on the trusted classification instead of on the request's own marker — and the refresh calls it in-process, together with the code behind the resume route. The refresh rides the channel bound relay's classification end to end instead of adding a grant: it passes `context.channelPrompt`, which the bridge turns into `qwen.channel.prompt` only from trusted context and the session child honours only from a trusted private parent, and no PR-binding backfill runs on the injected text. The turn carries every effect that classification has for the bound relay in the same sessions today (`Session.ts`), and accepts them: it skips the loop-detected rejection, records no branch checkpoint (it is not a rewind point), runs with the repeated-tool-failure guard off, does not count as a user submission turn, cannot have its model response cut short by queued or send-now user input, and its Stop hook is not interruptible. The transition key (group-suffixed with role-aware actions) is the `idempotencyKey`, so a retry to the same session within the daemon's lifetime deduplicates into the original admission. No display text is set: like the channel's bound relay today, the injected prompt appears in the session's transcript as sent, untrusted-data notice included, so the session's user sees exactly what the model received (the bridge keeps display texts only for channel-owned sessions). No new marker is introduced, so no strip list changes; a route test pins that a client body carrying `qwen.channel.prompt` without the worker credential gets no classification.
 - **Dormant sessions.** A bound session that is not live is restored through the resume path the channel accessor uses — PR A extracts the restore from the route's `restoreSessionHandler` into a function the route and the refresh share — then delivered to, and the refresh releases the client registration the restore mints once the delivered prompt settles, as the channel accessor does, so a woken session can still close when idle. Restores never run on the tick: the drain starts a dormant recipient's restore and admission without waiting for them (at most four at once; the rest wait for a later drain), the key stays in flight until they settle (§5), and a restore timeout therefore never stretches a tick. `wakeDormant` is on by default so a daemon restart does not strand events in `pending`; with `wakeDormant: false` the transition stays in `pending` and is delivered on the session's next live turn (the drain also runs on resume, through a hook PR A adds to that shared restore), and the 16-per-PR cap and the 7-day age limit (§5) apply with a log line, so nothing vanishes silently. Restore failures are split as the channel splits `BoundSessionGoneError` from `BoundSessionUnavailableError`. Only a permanent outcome — the channel's Gone set: the session record is gone (404), or a 409 `session_archived`, `worktree_session_superseded`, `worktree_marker_missing` or `worktree_reset_interrupted` — excludes the session; the drain then re-resolves the recipient among the remaining binders, within its role group with role-aware actions, and drops the transition with a log line only when a complete scan leaves no candidate. A temporary outcome — the restore timeout, a 503 (session limit, draining), a 429, a 409 `restore_in_progress` or `session_busy`, or `session_writer_conflict` — leaves the entry pending for the same recipient at the next drain. A restore returns `session_writer_conflict` while another daemon holds the session only when the session writer lease is on (`experimental.sessionWriterLease`, off by default for ordinary workspace sessions), and the lease covers daemon and ACP writers only: interactive and headless `qwen` CLI sessions stay outside it. A session another process writes live — a CLI session in a terminal, or a session another daemon over the same runtime base holds without the lease — can therefore be restored by the owner as a second writer, and the event lands in a copy nobody is using; with the lease on, the owner's copy can also fail after admission (`session_transcript_changed`, `session_writer_lost`), which counts as delivery. This is the exposure the channel's bound delivery has today, since it wakes sessions through the same restore path. Fencing interactive writers is out of scope, and operators who run several daemons over one runtime base turn the lease on. An excluded session rejoins the candidates when the owner's own unarchive, restore or re-bind path names it, and in any case after one hour. Nothing is ever published anywhere.
-- **Prompt text.** The channel's bound prompt shape and its hygiene: an event header, the untrusted-event-data notice, PR identity (repo, number, the title from the last view, URL), an `Event:` line and the summary (`ci_failure` names up to five failed checks from the rollup). Every line built from GitHub data — title, check names, branch names, the summary — passes through `sanitizePromptText` from `@qwen-code/channel-base` exactly as `buildBoundSessionPrompt` does (it folds CR/LF/TAB and the other C0/DEL controls and peels start-of-line tags, so a check-run `name:` taken from the PR branch's own workflow YAML cannot open a prompt line outside the `Event:` attribution), and the assembled body keeps the channel's 6,000-code-point cap with its visible truncation marker. The reply stays in the session.

The move also gives the trusted block a fixed label, `[Operator instruction — trusted]`, with the source on a `Source:` line under it: the content of the channel's old label, `[Operator instruction — trusted, from this channel's configuration]`, was 65 characters, one over the 64 that `sanitizePromptText` peels from a start-of-line tag, so an event body that began with a copy of it kept the brackets.

 **PR B** turns the switch on and adds the `sessionPrWatch` setting (§6), and in the same change removes the adapter watch — the watch pass, its task-store branches, the 30-PR cap and the CI re-check intervals — opening a one-minor-release deprecation window. B no longer watches from the watch state file: at the first connect after the upgrade it reads the file once to log how many undelivered entries it still held, then renames it with a `.retired` suffix so the line is logged once, and it retires every persisted `watch:` inbound task privately with a log line, never through the comment lane's public fallback. `connect()` keeps accepting `prWatchEvents` and the `watch:*` keys of `boundSessionActions`, logs exactly one warning naming `sessionPrWatch`, runs no watch pass, and the Web Shell descriptor marks them deprecated. With `sessionPrWatch` unset, the daemon reads them as aliases, per host: each GitHub channel this daemon hosts — loaded with the trust gating channel hosting already applies, so an untrusted workspace's settings never contribute (`packages/cli/src/serve/channel-workspace-grouping.ts` refuses to host its channels) — contributes its `prWatchEvents` as the event set and its `watch:*` actions (`watch:<type>` → `<type>`, `<role>:watch:<type>` → `<role>:<type>`, with `default` and `<role>:default` kept) for PRs on its web host. A channel whose `boundSessionActions` is non-empty stays role-aware under the alias even when none of its keys applies to PR-state events, so a channel that subscribed no role to watch events keeps receiving none. The alias counts as the effective set of the daemon that hosts the channel — one daemon per global qwen dir, the channel service reservation — for the owner claim (§2); if another daemon already owns the watch with an explicit set, that set governs. PRs on other hosts get nothing from the alias, an explicit `sessionPrWatch` wins, and two channels on one host take the union of their events, each type taking its actions — the role-aware mode and keys — from the first channel by name whose `prWatchEvents` includes that type and whose configuration delivers it (no actions, or a chain that resolves a template for it), with a logged conflict; the alias logs once when it takes effect. The alias views use the daemon's `gh`, not the channel's token, so a PR the channel could read but the daemon's `gh` cannot gets nothing from the alias: the daemon logs a warning naming the PR and the error class after two consecutive failed views of it, once per failure streak, and also warns once at startup when an alias is in effect while the refresh timer is not running. An operator whose channel connected with its own token makes the host's `gh` able to read those repositories before upgrading. An operator who turned the watch on in v0.26.7 therefore keeps receiving its transitions across the release that ships B for every PR the daemon's `gh` can view while the daemon that hosts the channel holds the watch (§2) and runs its refresh timer, at the latency of §6 instead of the channel's 60 seconds, with one boundary: before B the daemon kept no watch file, so its first sweep after the upgrade initialises every bound PR silently (§2), and a transition between the channel's last poll and that sweep, or one the channel had not delivered when the upgrade landed — before its next poll, still deferred by backpressure, or dead-lettered — is not delivered; B's one-time log line counts such entries.

 - **检测。** 扫描把新鲜 view——或 merged / closed PR 的 slim 列表状态——与该 PR 的监视文件比较，并在该 PR 的锁下以一次原子写入写入新观察、更新后的 `ciFired` 与检测到的转换。每次观察都带有其开始时间，开始时间早于文件 `observedAt` 的观察直接丢弃——既不比较也不写入——因此慢的 view 绝不会让基线倒退。由于该文件是唯一的基线，观察可以仍按 workspace 进行，而检测与投递以 PR 为范围：本 tick 所在 workspace 不可达、不受信或已退役的绑定者不持有任何可能落后、或会把一个转换检测第二次的副本；它重新可达时只是重新成为收件者候选。
 - **目标。** 整个 daemon 范围内每个 PR 只有一个收件会话——启用下文的角色化动作时每个角色组一个——绝不是每个 workspace 一个。收件者在投递时才惰性决定，且只针对尚未准入的 key（§5）：在绑定扫描覆盖的 workspace（受信 workspace 与 primary）中绑定该 PR 的合格会话里取最近活跃的那个（transcript mtime，再以 bridge 的 live 活动修正），即 channel 的传统规则，经该会话所属的 runtime 派发。扫描不完整时，排空为本次扫描未列出的每个会话保留最近一次列出它的扫描中的行——无论那次扫描完整与否，与适配器从每次快照重建其保留绑定相同——规模与适配器的保留上限相同（`MAX_PARTIAL_RETAINED`，最旧的先丢弃），一次完整扫描不再列出该会话时丢弃其保留行，因此暂时不可达的较新绑定者仍按最近活跃程度参与竞争——适配器出于同样的原因保留未列出的会话，使只列出较旧会话的不完整答案无法取代较新的那个——这样保留下来的会话胜出时，条目留在 pending 直到它可达。启用角色化动作时，这一规则在每个角色组内适用。检测与排空之间被归档或被别的会话超过的收件者不会丢任何东西：排空解析出下一个。归档会话、channel 自有会话（`sourceType: 'channel'`）与机器自有的隐藏目录会话（`isHiddenCatalogSource`：`agent-host`、`agent`）永远不是目标；不再注册、不再被扫描覆盖（不受信且非 primary）或 runtime 代际已退役（`assertGenerationOpen()`）的 workspace 记一行日志跳过，并在派发前立即重新解析。因此同一仓库注册了两个 workspace、各有一个会话跟随同一个 PR 时，无论中间是否崩溃，都只投递一次而非两次。

 - **扫描完整性。** 扫描在进程内被调用，为刷新提供 view 集合与收件者。在当前代码中 `partial` 表示有东西读不到——已注册但没有 runtime 的 workspace、列不出来的 chats 目录、读不了的 sidecar 或 transcript、拿不到的 live 会话列表——绝不是分页边界：扫描是每个 workspace 一次目录列表（#16241）。无法枚举的 workspace 本 tick 不提供 view，也不提供新列出的收件者——其会话的保留行仍参与竞争（目标）——此外再无任何东西依赖它，因为没有监视状态存放在它的 sidecar 中；`partial` 推迟所有否定性的决定：删除监视文件（§2；扫描不完整时只适用 7 天的 `lastBoundAt` 规则）、因没有合格绑定者而跳过某个角色组、因没有剩余候选而丢弃转换（下文）都只在完整扫描时判定；不完整的扫描中条目留在 `pending` 等待之后的排空，受 16 条上限与 7 天年龄上限约束（§5）。slim 列表的 `state` 刷新不受影响。
 - **归档与恢复。** 归档会话不改动该 PR 监视文件中的任何东西：该会话只是离开收件者候选，其 sidecar 保留顶层 `state` 并照常被刷新。从归档恢复的会话重新加入候选。若另有绑定者一直在跟随该 PR，文件是新的，恢复的会话此后收到转换；若无人跟随该 PR，其文件已被删除（§2），该 PR 静默初始化，因此会话归档期间发生的变化不会补投给它——恢复是用户操作，刷新过的顶层 `state` 已经在侧栏显示了这些变化。在最后一个绑定者离开后 7 天内、且扫描一直不完整时的恢复，会从最后一次观察继续，把间隔期内的转换投递一次。
 - **机制。** PR A 把 prompt 准入从路由处理函数中抽成一个路由与刷新共用的函数——幂等环、分类与回填跳过随之迁移，回填跳过改按受信分类判断，而不是按请求自带的标记——刷新在进程内调用它，以及恢复路由背后的代码。刷新全程沿用 channel 绑定中继的分类，而不是新增一种授权：它传入 `context.channelPrompt`，bridge 只从受信 context 把它变成 `qwen.channel.prompt`，会话子进程只在受信的私有父进程下认可它，注入文本也不做 PR 绑定回填。该回合带有这一分类今天在同样的会话中对绑定中继所具有的全部效果（`Session.ts`），并接受它们：跳过循环检测拒绝，不记录分支检查点（它不是 rewind 点），关闭重复工具失败防护，不计为用户提交回合，排队或立即发送的用户输入无法打断其模型响应，其 Stop hook 不可中断。以转换 key（启用角色化动作时加组后缀）作为 `idempotencyKey`，因此 daemon 生命周期内对同一会话的重试会去重到原始准入。不设置显示文本：与 channel 今天的绑定中继一样，注入的 prompt 在会话 transcript 中按原样显示，包括不可信数据提示，因此会话的用户看到的正是模型收到的内容（bridge 只为 channel 自有会话保留显示文本）。不新增任何标记，因此剥离清单无需改动；一个路由测试钉住：不带 worker 凭据、携带 `qwen.channel.prompt` 的客户端请求体得不到分类。
 - **休眠会话。** 已绑定但不在线的会话通过 channel 访问器所用的恢复路径恢复——PR A 把恢复从路由的 `restoreSessionHandler` 中抽成路由与刷新共用的函数——后再投递，并像 channel 访问器那样在投递的 prompt 结束后释放恢复所创建的客户端注册，使被唤醒的会话空闲时仍能关闭。恢复绝不在 tick 上运行：排空启动休眠收件者的恢复与准入后不等待它们（同时最多四个，其余等之后的排空），key 在它们结束前保持在飞（§5），因此恢复超时绝不会拉长 tick。`wakeDormant` 默认开启，这样 daemon 重启不会让事件滞留在 `pending` 中；`wakeDormant: false` 时转换留在 `pending`，在该会话下一次 live 回合投递（排空在恢复时也会运行，经 PR A 在该共用恢复中加入的钩子），每个 PR 16 条的上限与 7 天年龄上限（§5）照常适用并记日志，不会静默消失。恢复失败按 channel 区分 `BoundSessionGoneError` 与 `BoundSessionUnavailableError` 的方式划分。只有永久性结果——即 channel 的 Gone 集合：会话记录已不存在（404），或 409 `session_archived`、`worktree_session_superseded`、`worktree_marker_missing`、`worktree_reset_interrupted`——才排除该会话；排空随即在其余绑定者中重新解析收件者（启用角色化动作时在其角色组内），只有当完整扫描没有留下任何候选时才丢弃该转换并记一行日志。临时性结果——恢复超时、503（会话数上限、draining）、429、409 `restore_in_progress` 或 `session_busy`，或 `session_writer_conflict`——让条目留在 pending，在下一次排空时投给同一收件者。只有在会话写锁开启时（`experimental.sessionWriterLease`，普通 workspace 会话默认关闭），另一个 daemon 持有该会话时恢复才会返回 `session_writer_conflict`，而且该写锁只覆盖 daemon 与 ACP 写入者：交互式与 headless 的 `qwen` CLI 会话不在其内。因此另一个进程正在写入的会话——终端里的 CLI 会话，或共用运行时根目录的另一个 daemon 在未开启写锁时持有的会话——可能被 owner 作为第二个写入者再恢复一份，事件投进一个无人使用的副本；开启写锁时，owner 的副本也可能在准入之后失败（`session_transcript_changed`、`session_writer_lost`），而准入即视为投递。channel 的绑定投递今天也有同样的风险，因为它经同一恢复路径唤醒会话。为交互式写入者加防护不在本设计范围内，在一个运行时根目录上运行多个 daemon 的运维者应开启该写锁。被排除的会话在 owner 自己的取消归档、恢复或重绑路径提到它时重新成为候选，无论如何一小时后也会恢复。任何地方都不会公开发布。

 **PR B** 打开该开关并加入 `sessionPrWatch` 设置（§6），并在同一个改动中移除适配器监视——监视通道、任务存储中的监视分支、30 个 PR 的上限与 CI 复查间隔——开启一个 minor 版本的弃用窗口。B 不再依据监视状态文件做监视：升级后首次连接时读一次该文件，记录其中仍有多少未投递条目，然后给它加上 `.retired` 后缀改名，使这行日志只记一次；并把每个持久化的 `watch:` 入站任务私下退役并记日志，绝不经评论车道的公开回退。`connect()` 继续接受 `prWatchEvents` 与 `boundSessionActions` 的 `watch:*` 键，只记一条点名 `sessionPrWatch` 的告警，不跑监视通道，Web Shell 描述符将其标为已弃用。`sessionPrWatch` 未设置时，daemon 按 host 把它们读作别名：本 daemon 承载的每个 GitHub channel——按 channel 承载已有的信任门控加载，因此不受信 workspace 的设置绝不会参与（`packages/cli/src/serve/channel-workspace-grouping.ts` 拒绝承载其 channel）——为其 web host 上的 PR 提供自己的 `prWatchEvents` 作为事件集合，以及自己的 `watch:*` 动作（`watch:<type>` → `<type>`，`<role>:watch:<type>` → `<role>:<type>`，`default` 与 `<role>:default` 保留）。`boundSessionActions` 非空的 channel 在别名下仍是角色化的，即使它没有任何键适用于 PR 状态事件，因此没有为任何角色订阅监视事件的 channel 仍然收不到它们。在 owner 认领中（§2），别名算作承载该 channel 的 daemon 的生效集合——每个 global qwen dir 只有一个这样的 daemon，即 channel 服务的预留；若另一个带显式集合的 daemon 已持有监视，则以那个集合为准。其它 host 上的 PR 从别名得不到任何东西，显式的 `sessionPrWatch` 优先；同一 host 上的两个 channel 取事件的并集，每种类型的动作——角色化模式与键——取自 `prWatchEvents` 包含该类型、且其配置会投递该类型（没有动作，或有能为它解析出模板的链）的按名字排第一的 channel，并记录冲突；别名生效时记一次日志。别名的 view 使用 daemon 的 `gh`，而不是 channel 的 token，因此 channel 读得到而 daemon 的 `gh` 读不到的 PR 从别名得不到任何东西：daemon 在对它连续两次 view 失败后记一条点名该 PR 与错误类别的告警，每个失败周期一次；别名生效而刷新定时器未运行时，也在启动时告警一次。channel 用自己 token 连接的运维者应在升级前让宿主的 `gh` 能读到这些仓库。因此在 v0.26.7 上开启了监视的运维者跨过 B 所在的版本，在承载该 channel 的 daemon 持有监视（§2）且运行其刷新定时器期间，对 daemon 的 `gh` 能 view 的每个 PR 仍收到这些转换，只是延迟从 channel 的 60 秒变为 §6 所述的延迟；有一个边界：B 之前 daemon 不保存任何监视文件，因此升级后的第一次扫描静默初始化每个绑定 PR（§2），channel 最后一次轮询与这次扫描之间的转换、以及升级落地时 channel 尚未投递的转换——还没到下一次轮询、仍因背压被推迟、或已进死信——都不会投递；B 的那一次日志会统计这类条目。

 3. **One winner per role, fan-out across roles — generalizing base Key decision 4.** The base design rejected broadcast because it "multiplies model cost and produces duplicate GitHub actions." Role differentiation removes the duplicate-action objection (different roles, different surfaces), and one winner per role bounds cost by the role count (≤ 4), not the session count. The generalization is opt-in: with the field absent, the base decision stands verbatim.
 4. **Namespaced closed vocabularies.** `watch:` prefixes resolve the real `state_change` collision between the two lanes; role prefixes partition the map; closed key and role sets turn typos into validation errors instead of silently inert config. Shared exported constants keep UI options, validator, and emit path from drifting.
 5. **The map is a per-role subscription.** No matching key → the role skips the event. Fanning generic prompts to every role would recreate the noise the base design's single winner avoided; subscription-by-key gives operators one surface for both "who hears what" and "what they are told." Absent field → legacy single-winner generic prompt, byte-identical.

 7. **Instruction, not execution.** The rendered template is a prompt turn, not a command runner. The base design's "no channel takeover" decision and the session's approval-mode boundary stand. A hard guarantee needs a deterministic hook mechanism — future work, not smuggled in here.
 8. **Per-(event, target) durability, event-level admission identity.** Local task keys carry the target; admission keys do not (the per-session ring makes fan-out safe without a format change). Pending→fired moves only after all matched targets are claimed, so a crash mid-fan-out re-claims exactly the missing targets. Ordering is per (PR, target): one stuck role never head-of-line-blocks another.
 9. **Public fallback only at zero live targets AND no prior private delivery.** A partially delivered event never also goes public: the durable delivery ring proves a prior acceptance even after every follower disappeared, and current-follower counts alone cannot. A map-skipped role is an operator decision, not an absence — and under a partial scan even the skip is unprovable, so the event defers instead of being consumed. The base design's irreversible-public-reply guard is preserved under fan-out.

With the example configuration and three role-bound sessions on one PR, a head advance delivers exactly one prompt to the review winner and one to the verify winner, each with the correctly rendered operator block (`%pr%`/`%repo%`/`%url%` values, `Role:` line); the fix session receives nothing, and no reply is auto-posted.
 3. A CI failure reaches only the fix role; a new comment reaches only the fix role; a `review_requested` notification reaches only the review role. Resolution order holds at all four levels, and watch events never match bare reason keys nor vice versa (`state_change` both ways).

+# Prompt Context Placement
+
+[English](2026-11-04-prompt-context-placement.md) | [简体中文](2026-11-04-prompt-context-placement.zh-CN.md)
+
+**Status:** Implemented
+
+**Issue:** [#16259](https://github.com/QwenLM/qwen-code/issues/16259)
+
+## Problem
+
+A user submitted one complete 2461-character task with seven numbered steps.
+The model answered "I have not received a specific task yet", and its reasoning
+read "The user only provided a system reminder about available skills ... no
+specific task."
+
+The instruction reached the provider intact. Its position did not survive
+assembly. A fresh turn's user entry is built from independent sources:
+
+1. Per-turn `<system-reminder>` parts, prepended ahead of the prompt (plan mode,
+   arena, output style, workflow mode, one-shot notices, recalled memory).
+2. The user's own parts.
+3. The `<qwen:user-prompt-submit-context>` block carrying hook and Mod context,
+   appended after the prompt.
+4. The memory catalog snapshot, appended after that.
+
+The real instruction therefore sits mid-entry, with injected context on both
+sides. Three independent caps (`MAX_SKILL_LISTING_CHARS = 8000`,
+`MAX_INDEX_CHARS = 25_000` per index with two indexes injected, plus unbounded
+hook context) let the surrounding blocks reach tens of kilobytes, at which point
+a flash-class model reads the envelopes and misses the task.
+
+## Design
+
+Reorder the outgoing request so the user's own text is the last content of the
+pending turn. `LlmChat.getRequestHistoryForRoute()` already produces a
+request-only copy of history; a new `movePromptContextAheadOfUserText()` pass
+runs on that copy, moving the injected run that trails the user's text to just
+ahead of it.
+
+Injected parts are recognized as a wrapped `<system-reminder>`, a whole
+`<qwen:user-prompt-submit-context>` block, or a part marked
+`AUTO_MEMORY_SNAPSHOT_METADATA`. Everything else is the caller's own content and
+keeps its relative order.
+
+Only the contiguous injected run after the caller's LAST own part moves. The
+pass walks back over a contiguous run of own parts, so a reminder the caller
+placed between two of its own parts bounds that run and keeps its position.
+
+Three cases are left untouched:
+
+- Leading `functionResponse` parts. A `tool_result` block must immediately
+  follow the model's `tool_use`; Anthropic-compatible backends reject text ahead
+  of it.
+- A `functionResponse` that is not in the leading run. That position is the
+  caller's own ordering, so the entry is returned unchanged rather than hoisting
+  the tool result to the front.
+- The volatile tail from the first `REATTACH_BOUNDARY_METADATA` marker onward.
+  That is one contiguous region — a marker, then a label and an image per
+  replayed image — and the provider cache passes count it as trailing blocks to
+  place their per-turn breakpoint before it (#11627). Splitting or relocating it
+  would anchor the breakpoint on a block no later request contains.
+
+## Design decisions
+
+**Request-only, not history.** The trailing position of the hook block is
+load-bearing for stored history. `projectUserTranscriptForDisplay()` treats a
+complete final tagged part as pairing evidence for `displayText`, and
+`restoreUserPromptSubmitContextReceipt()` re-stamps only the final part on
+resume. Reordering the stored entry would break the display projection and
+re-deliver already-delivered hook context every turn. Only the request copy
+changes, so the transcript, resume, deduplication, and rewind contracts are
+untouched.
+
+**Every user entry, not just the pending one.** The next request re-sends the
+previous turn's entry from stored history, so reordering only the pending entry
+would make an entry's wire shape depend on its position: request N would send
+`[reminder, hook, catalog, ...prompt]` while request N+1 rebuilds the same entry
+as `[reminder, ...prompt, hook, catalog]`. The shared provider prefix would then
+end at the leading reminder and the injected blocks would be re-prefilled at
+full input price on every turn — the failure mode `REATTACH_BOUNDARY_METADATA`
+exists to prevent (#11627). Applying the same rule to every user entry in the
+request copy keeps each entry's wire shape position-independent, so request N+1
+extends request N's prefix exactly. Stored history is still untouched.
+
+**One pass at the send boundary, not per producer.** Reminders, hook context,
+IDE context and the catalog are injected by different modules on different
+frontends (TUI, headless, ACP, the shared agent loop). Fixing the order at the
+single point where every main-turn request is assembled covers all of them
+without four parallel edits that can drift — with one consumer that bypasses
+that point and must call the pass itself: the compaction side-query's
+`promptCacheSharing` payload is built from `getHistoryShallow(true)` inside
+`chatCompressionService.ts`, so it reorders its own copy, while the cold path
+and the post-compact image restore keep the stored order.
+
+**No budget change.** This addresses position only. The aggregate cap across
+injected blocks, moving the catalog off the user tail entirely, and the CJK
+token undercount in the always-on-context warning remain separate work
+(#16184, #14976).
+
+## Constraints
+
+- A turn whose parts are all tool results, all injected context, or already
+  ordered is returned unchanged.
+- Classification spans the whole entry, which is what bounds the moving run.
+  Only the contiguous injected run after the caller's last own part is
+  relocated, so a caller-authored part shaped like either envelope that ends
+  the entry is treated as injected and moves ahead of the caller's text.
+- Side queries (`getRequestHistoryForRoute` without a pending user turn) are
+  unaffected.
+
+## Validation
+
+- A multi-part prompt with a leading reminder, a trailing hook block and a
+  catalog snapshot is sent as `[reminder, hook, catalog, ...prompt]`, while
+  stored history keeps `[reminder, ...prompt, hook, catalog]`.
+- A tool-result turn keeps its `functionResponse` first and its reattach region
+  (marker, label, image) intact and last.
+- A prompt with no injected parts keeps its original part order.
+- A reminder the caller placed between two of its own parts stays there; only
+  the appended block after the last own part moves.
+- The compaction side-query's cache-sharing payload carries the same reordered
+  entries, so it reuses the prefix the main request just warmed, while the cold
+  path and the post-compact image restore keep the stored order
+  (`packages/core/src/services/chatCompressionService.test.ts`).
+- The helper itself is pinned directly, including the entry whose parts are all
+  tool results, by `packages/core/src/core/prompt-context-order.test.ts`.
+- Existing catalog budget, deduplication, and cache-boundary assertions still
+  hold. Three assertions that pinned the old order were updated: the pending-turn
+  check now asserts the catalog is present and the user text is last; the
+  durable-recovery check now asserts the request holds the same entries and
+  parts as history with the catalog moved ahead of the recovery prompt; and the
+  multi-turn prefix check now compares each request against the previous
+  request. The prefix check could not keep its old form: a reordered pending
+  entry deliberately differs from its stored shape, so request versus stored
+  history is no longer equal. Presence of the injected parts is still guarded,
+  by the two checks above and by the multi-turn test's own snapshot-count
+  assertion, not by the prefix comparison.
+
+`packages/core/src/core/llm-chat.test.ts`: 720 passed.
+
+## Open questions
+
+Whether the catalog belongs in the user entry at all, and what aggregate budget
+and eviction order the per-turn blocks should share, are tracked separately.

+# 提示词上下文的位置

+[English](2026-11-04-prompt-context-placement.md) | [简体中文](2026-11-04-prompt-context-placement.zh-CN.md)
+
+**状态：** 已实现
+
+**Issue：** [#16259](https://github.com/QwenLM/qwen-code/issues/16259)
+
+## 问题
+
+用户提交了一条完整的 2461 字符任务，包含 7 个编号步骤。模型回复"目前还没有收到
+具体任务"，其 thinking 原文是"The user only provided a system reminder about
+available skills ... no specific task."
+
+指令完整送达了服务商，但它的位置在组装过程中没有保住。一次新轮次的 user 条目由
+若干独立来源拼成：
+
+1. 每轮的 `<system-reminder>` 分片，前置在正文之前（plan mode、arena、输出风格、
+   workflow mode、一次性通知、召回的记忆）。
+2. 用户自己的分片。
+3. 承载 hook 与 Mod 上下文的 `<qwen:user-prompt-submit-context>` 块，追加在正文
+   之后。
+4. 记忆目录快照，再追加在其后。
+
+于是真实指令落在条目中段，两侧都是注入上下文。三个各自独立的上限
+（`MAX_SKILL_LISTING_CHARS = 8000`、每个索引 `MAX_INDEX_CHARS = 25_000` 且会注入
+两个索引，加上无上限的 hook 上下文）让包围它的块可以达到几十 KB，此时 flash 级别
+的模型只读到这些信封，漏掉了任务。
+
+## 设计
+
+重排外发请求，让用户自己的正文成为该轮次的最后一段内容。
+`LlmChat.getRequestHistoryForRoute()` 本就产出仅用于请求的历史副本；新增的
+`movePromptContextAheadOfUserText()` 在该副本上运行，把尾随在用户正文之后的注入
+块整体移到正文之前。
+
+注入分片的识别依据是：被 `<system-reminder>` 包裹、是完整的
+`<qwen:user-prompt-submit-context>` 块，或带有 `AUTO_MEMORY_SNAPSHOT_METADATA`
+标记。其余一律视为调用方自己的内容，保持相对顺序。
+
+只搬动位于调用方**最后一个**自有分片之后的连续注入区段。该过程只向前回溯一段
+连续的自有分片，因此调用方放在自己两个分片之间的提醒会成为该区段的边界，保持
+原位。
+
+有三类情况原样保留：
+
+- 前导的 `functionResponse` 分片。`tool_result` 块必须紧跟模型的 `tool_use`；
+  Anthropic 兼容后端会拒绝排在它之前的文本。
+- 不在前导区段内的 `functionResponse`。那个位置属于调用方自己的排序，因此整条
+  条目原样返回，而不是把工具结果提到最前。
+- 从第一个 `REATTACH_BOUNDARY_METADATA` 标记起的易变尾部。它是一个连续区域——
+  一个标记，随后每张回放图片各有一个标签和一张图片——各服务商的缓存处理会把它按
+  尾部块计数，从而把每轮断点放在它之前（#11627）。拆开或搬走它会让断点落在后续
+  请求不再包含的块上。
+
+## 设计决策
+
+**只改请求，不改历史。** hook 块位于尾部这一点对已存历史是有承载作用的。
+`projectUserTranscriptForDisplay()` 把完整的末尾 tagged 分片当作 `displayText`
+的配对证据，`restoreUserPromptSubmitContextReceipt()` 在 resume 时也只对最后一
+个分片重新盖章。重排已存条目会破坏展示投影，并让已投递的 hook 上下文每轮重复
+投递。因此只改请求副本，transcript、resume、去重与 rewind 的契约都不受影响。
+
+**重排作用于每条 user 条目，而不只是待发送的那条。** 下一轮请求会从已存历史里
+重新发送上一轮的条目；只重排待发送条目会让一条条目的线上形状取决于它的位置：
+第 N 轮发出 `[提醒, hook, 目录, ...正文]`，第 N+1 轮却把同一条目重建成
+`[提醒, ...正文, hook, 目录]`。两次请求的公共前缀就只到开头的提醒为止，注入块
+每轮都要按全价重新 prefill——这正是 `REATTACH_BOUNDARY_METADATA` 要防止的失效
+模式（#11627）。对请求副本里每条 user 条目套用同一条规则，条目的线上形状就与
+位置无关，第 N+1 轮请求严格扩展第 N 轮的前缀。已存历史仍然不动。
+
+**在发送边界统一处理，而不是逐个生产者修改。** 提醒、hook 上下文、IDE 上下文和
+目录由不同模块在不同前端（TUI、headless、ACP、共享 agent loop）注入。在每轮主
+请求组装的唯一位置修正顺序，可以一次覆盖全部路径，避免四处并行修改后各自漂移；
+只有一个消费方绕过该位置、必须自己调用这次重排：压缩侧查询的 `promptCacheSharing`
+载荷在 `chatCompressionService.ts` 里由 `getHistoryShallow(true)` 构建，因此它
+重排自己那份副本，而冷路径与压缩后的图片恢复正常仍读取已存顺序。
+
+**不改预算。** 本次只处理位置。跨注入块的总量上限、把目录彻底移出 user 尾部，
+以及 always-on-context 告警对中文 token 的低估，仍是独立工作（#16184、#14976）。
+
+## 约束
+
+- 分片全为工具结果、全为注入上下文，或顺序本已正确的轮次，原样返回。
+- 判定覆盖整条 entry，这正是移动区段能被界定的原因：只有「caller 最后一个自有
+  分片之后」连续的那段注入内容会被前移；因此 caller 自撰、形似两种信封之一、并
+  位于结尾的分片会被当作注入内容，移到 caller 正文之前。
+- 侧查询（调用 `getRequestHistoryForRoute` 时没有待发送 user 轮次）不受影响。
+
+## 验证
+
+- 一条多分片提示词，带前导提醒、尾随 hook 块和目录快照，外发顺序为
+  `[提醒, hook, 目录, ...正文]`，而已存历史仍是 `[提醒, ...正文, hook, 目录]`。
+- 工具结果轮次保持 `functionResponse` 在最前，reattach 区域（标记、标签、图片）
+  完整且位于最后。
+- 没有注入分片的提示词保持原有分片顺序。
+- 调用方放在自己两个分片之间的提醒保持原位；只有最后一个自有分片之后追加的块
+  会移动。
+- 压缩侧查询的 cache-sharing 载荷携带同一份重排后的条目，从而复用主请求刚预热
+  过的前缀，而冷路径与压缩后的图片恢复正常仍读取已存顺序
+  （`packages/core/src/services/chatCompressionService.test.ts`）。
+- 这个辅助函数本身由 `packages/core/src/core/prompt-context-order.test.ts` 直接
+  钉住，包括「分片全为工具结果」的那条条目。
+- 既有的目录预算、去重与缓存边界断言仍然成立。三处固定旧顺序的断言已更新：
+  待发送轮次的检查改为断言目录存在且用户正文在最后；持久化恢复的检查改为断言
+  请求与历史持有相同的条目和分片，只是目录被移到了恢复提示词之前；多轮前缀的
+  检查改为每一轮请求与上一轮请求比较。前缀检查无法保留原来的形式——重排之后
+  待发送条目本就不再等于它的已存形态，所以「请求 vs 已存历史」不再成立。注入
+  分片是否存在仍然有人兜底——由上面两处检查，以及多轮测试自己的快照数量断言，
+  而不是由前缀比较负责。
+
+`packages/core/src/core/llm-chat.test.ts`：720 项通过。
+
+## 待定问题
+
+目录是否应该留在 user 条目内，以及每轮注入块应共享怎样的总量预算与淘汰顺序，
+另行跟踪。

+# Ask User "Ask for details" Side Task
+
+[English](2026-11-06-ask-user-details-side-task.md) | [简体中文](2026-11-06-ask-user-details-side-task.zh-CN.md)
+
+Status: implemented and verified (unit tests, mock-daemon visuals, and a
+real-daemon + real-model E2E round; evidence in `.qwen/e2e-tests/`).
+
+## Problem
+
+When an `ask_user_question` permission is pending, Web Shell hides the main
+composer (`composerHidden`) and the btw shortcut ignores `pendingApproval`.
+The user can only pick an option, type a free-text answer, or Ignore. There is
+no way to ask a follow-up question about the pending question itself — for
+example what an option means, what it changes, or what the risks are — without
+first committing to an answer or discarding the question.
+
+## Current state
+
+- `/btw <question>` runs a lightweight side question (`btwSessionStream`) that
+  does not enter the main conversation context. It is handled only by the main
+  view composer.
+- `/btw side <question>` creates a side task when the daemon advertises
+  `session_side_task` and a workspace session exists (`sideTasksAvailable`):
+  `createSideTask(initialPrompt)` opens a right-panel tab, and
+  `createSideTaskSession` provisions a child session that inherits the parent
+  transcript context. The tab's `initialPrompt` is sent as the child session's
+  first prompt.
+- Files written by a session surface as turn outputs; `.html` files are
+  renderable artifacts and open in the right panel's HTML preview.
+- The pending AskUser panel (`AskUserQuestion`) offers Submit / Ignore /
+  Previous / Next and an "Other" free-text input, but no details action.
+
+## Goals
+
+- Let the user learn the details of a pending question before answering,
+  without answering it, discarding it, or polluting the main conversation.
+- Reuse the existing side-task infrastructure end to end; no daemon changes.
+- The explanation is delivered as a self-contained single-file HTML document
+  written in controlled, unambiguous sentences (ASD-STE100 sentence rules),
+  in the UI language.
+
+## Non-goals
+
+- No details action in split-view panes or inside side-task panes. This matches
+  `/btw side`, which is also main-view-only; a pane-scoped variant would need
+  per-pane parent-session scoping that the side-task panel does not have today.
+- No new daemon routes, capabilities, or settings.
+- No automatic answering: the side task must never submit the pending
+  permission or send a prompt to the main session.
+
+## Proposed solution
+
+1. `AskUserQuestion` accepts an optional `onAskDetails?: () => void`. When
+   provided, the actions row renders an "Ask for details" text button (muted
+   styling, left of Ignore). The button is outside the option radiogroup, so
+   option digit shortcuts and roving-tabindex navigation are unchanged. It is
+   disabled while a submission is in flight.
+2. App wires the callback only for the main-view overlay, gated on
+   `sideTasksAvailable` (same gate as `/btw side`). The callback formats the
+   pending payload with `formatAskUserQuestions(rawInput)` — a language-neutral
+   snapshot of numbered questions with option labels/descriptions — and calls
+   `createSideTask(t('askUser.detailsPrompt', { questions }))`.
+3. The localized prompt template instructs the side task to: read the relevant
+   code and context first; mark unverified claims; explain each question's
+   background and every option's meaning, differences, impact, and risks; give
+   a recommendation with reasons; not answer for the user or change the main
+   session; write a self-contained single-file HTML (inline CSS, no external
+   resources) under `.qwen/tmp/` using ASD-STE100 sentence rules (one idea per
+   sentence, active voice, short sentences, one term per concept, conditions
+   before actions, lists for three or more items, no metaphors or
+   exclamations); keep code, commands, paths, and config keys verbatim; reply
+   with the file path and a one-sentence summary.
+4. The HTML file appears as a turn output in the side-task chat and opens in
+   the existing right-panel HTML preview. The pending question stays pending;
+   the user returns to the main view to answer or Ignore.
+
+## Design decisions
+
+- **Side task, not lightweight btw.** The details conversation may need code
+  reading, file writing, and follow-up turns; a side task is a full child
+  session with inherited context, while `btwSessionStream` is a single-shot
+  answer. The HTML deliverable also requires file tools.
+- **Prefilled prompt, not an empty draft.** The user's intent ("explain this
+  pending question") is known at click time; prefilling removes a typing step
+  and pins the scope. The user can still steer with follow-up prompts.
+- **Prompt-carried style rules.** The side-task model does not share the
+  user's personal memory, so the controlled-language and HTML requirements
+  must be self-contained in the prompt. Only the core sentence rules are
+  included; heavier verification rituals stay out of the product default.
+- **Optional prop, conditional render.** Hosts without a side-task surface
+  (embedded hosts, split panes, daemons without the capability) simply do not
+  pass the callback, and the button does not exist. No disabled-state UI.
+- **UI language for the explanation.** The prompt template is localized
+  (en/zh-CN; ru falls back to en via the existing i18n fallback), so the
+  explanation language follows the UI language rather than the daemon's
+  output-language setting.
+- **One details task per pending question.** The details tab uses a stable id
+  derived from the permission request id (a uuid; tabs are already bucketed
+  per parent session) and is upserted, not appended: repeat clicks focus the
+  existing tab instead of provisioning duplicate child sessions. The
+  question-to-child association is also persisted per parent session
+  (localStorage), so it outlives the tab: closing the details tab and clicking
+  again reopens the same child, and a child reopened from the side-task
+  catalog under its own `side-task:<sessionId>` tab is focused rather than
+  duplicated. Four lifecycle edges are covered: the association is recorded
+  even when the draft tab closes before creation resolves (the parent identity
+  is captured when creation starts, since the server does not cancel it); the
+  reopened tab retains the explanation prompt, and the pane's empty-session
+  guard sends it only while the child has no user prompt yet (media-only
+  messages — image, file, or resource link — count; they submit with empty
+  text), so a prompt interrupted by a close is delivered exactly once and
+  never re-sent; a catalog-reopened tab
+  carries no prompt of its own, so clicking details again supplies the pending
+  prompt on the matched tab before focusing it, letting the same guard deliver
+  it to a still-empty child; and archiving a child invalidates its
+  association, because the daemon's load route rejects
+  archived sessions (409 `session_archived`) — the next click provisions a
+  fresh child instead of attaching an unloadable one. Archive can happen from
+  any surface (the side-task panel, the sidebar session row, the overview
+  panel, the activity catalog) or another browser tab, so the binding is
+  validated at the read site: a click confirms the child is still in the
+  parent's active side-task list and forgets it otherwise, rather than trusting
+  the persisted id. When the open same-id tab is bound to a different child
+  than the validated binding (a tab restored from another browser tab's copy),
+  the upsert replaces it so the pane attaches to the active child instead of
+  keeping an unloadable pane. One entry per parent supersedes the resolved question's
+  association, keeping the store bounded; re-recording a parent moves it to the
+  newest key slot so the oldest-first eviction never drops a live, frequently
+  used parent. The tab id stays short because the pane derives its daemon
+  clientId as `side-task:<parentSessionId>:<tabId>` and the daemon rejects
+  client ids over 128 characters; an App-level test pins that budget with
+  uuid-length inputs through the real derivation. `/btw side` keeps its unique
+  per-invocation draft id.
+- **The child is named from the question.** The explanation prompt leads with
+  the question snapshot, so the pane's generic first-prompt naming (the first
+  200 code points) yields a question-derived title in the tab strip and the
+  side-task catalog, instead of the identical instruction boilerplate for every
+  details task.
+- **The snapshot carries selection semantics.** Multi-select questions are
+  marked `[multiSelect]` so the explanation covers combinable options without
+  relying on the inherited transcript alone.
+- **The actions row wraps.** A fifth button can push the row past narrow
+  viewports, and a flex-end row overflows to the left — invisible to
+  `scrollWidth`. The row wraps, and a 320px multi-question regression test
+  asserts every action button stays inside the panel and stays clickable.
+
+## Constraints and risks
+
+- The side task inherits the parent transcript at creation time; the pending
+  question is part of that context, and the prompt embeds a snapshot as well,
+  so the explanation stays scoped even if the parent transcript is long.
+- `.qwen/tmp/` is the agent's scratch directory (git-ignored in this repo).
+  In workspaces where it is not ignored, the file is still a normal workspace
+  file the user can delete; nothing is committed automatically.
+- The button must not disturb the panel's keyboard contract: it lives in the
+  actions row, is not an option, and does not register digit shortcuts.
+- Side-task creation can fail (daemon error, policy flip). Failure handling is
+  inherited from the existing `/btw side` path (toasts, tab guards); the
+  details action adds no new failure mode.
+
+## Validation plan
+
+- Unit: `formatAskUserQuestions` formatting, trimming, malformed-entry
+  skipping (`askUserPermission.test.ts`).
+- Unit: button hidden without the callback; click invokes the callback without
+  submitting; outside the option group and digit shortcuts; disabled while
+  submitting (`AskUserQuestion.test.tsx`).
+- Unit: App wiring — with `session_side_task`, the pending-question details
+  action creates a side-task tab whose `initialPrompt` contains the question
+  text, the STE100 instruction, and the `.qwen/tmp/` target; no
+  `submitPermission`/`sendPrompt` on the main session; without the capability
+  the callback is not offered (`App.test.tsx`).
+- Visuals: `client/e2e/visuals/ask-user-details.spec.ts` (mock daemon, real
+  Chromium, dark/light, zh-CN UI) — the button renders on the pending panel,
+  clicking it opens the side-task tab, and the question stays pending.
+- E2E: `.qwen/e2e-tests/` — real daemon, pending AskUser, click details,
+  verify side task creation, HTML artifact preview, and that the main question
+  remains pending. Executed 2026-11-06 against a real daemon and model; all
+  steps passed (evidence: `.qwen/e2e-tests/ask-details-e2e-20261106/`).
+
+## Acceptance criteria
+
+- With the side-task capability, a pending AskUser panel shows "Ask for
+  details"; clicking it opens a side task that starts explaining the question
+  without any main-session answer being submitted.
+- Without the capability (or in embedded/split surfaces), the panel is
+  unchanged.

+# Ask User「问细节」侧边任务
+
+[English](2026-11-06-ask-user-details-side-task.md) | [简体中文](2026-11-06-ask-user-details-side-task.zh-CN.md)
+
+状态：已实现并验证（单元测试、mock daemon 视觉验证、真实 daemon + 真实模型
+E2E 轮；证据见 `.qwen/e2e-tests/`）。
+
+## 问题
+
+当 `ask_user_question` 权限待回答时，Web Shell 会隐藏主输入框
+（`composerHidden`），btw 快捷键也会忽略 `pendingApproval` 状态。用户只能选择
+选项、输入自由文本答案或忽略。此时没有任何途径就待答问题本身追问——例如某个
+选项是什么意思、会改动什么、有什么风险——除非先提交一个答案或丢弃这个问题。
+
+## 现状
+
+- `/btw <问题>` 走轻量侧边提问（`btwSessionStream`），不进入主对话上下文。
+  它只由主视图输入框处理。
+- `/btw side <问题>` 在 daemon 声明 `session_side_task` 且存在工作区会话
+  （`sideTasksAvailable`）时创建侧边任务：`createSideTask(initialPrompt)`
+  打开右侧面板 tab，`createSideTaskSession` 创建继承父会话转录上下文的子会话。
+  tab 的 `initialPrompt` 作为子会话的首条提示词发送。
+- 会话写出的文件会作为回合产物展示；`.html` 文件是可渲染产物，可在右侧面板的
+  HTML 预览中打开。
+- 待答 AskUser 面板（`AskUserQuestion`）提供提交 / 忽略 / 上一题 / 下一题与
+  「其他」自由输入，但没有问细节的入口。
+
+## 目标
+
+- 让用户在作答前了解待答问题的细节，且不提交答案、不丢弃问题、不污染主对话。
+- 端到端复用现有侧边任务基础设施；不改 daemon。
+- 解释以自包含单文件 HTML 交付，用受控、无歧义的句式（ASD-STE100 句式规则）
+  写作，语言跟随 UI 语言。
+
+## 非目标
+
+- 不在 split view 面板或侧边任务面板内提供问细节入口。这与 `/btw side` 一致
+  （后者也只在主视图可用）；按面板区分的变体需要侧边任务面板目前不具备的
+  按面板父会话作用域能力。
+- 不新增 daemon 路由、能力声明或设置项。
+- 不自动作答：侧边任务绝不能提交待答权限，也不能向主会话发送提示词。
+
+## 方案
+
+1. `AskUserQuestion` 接受可选 `onAskDetails?: () => void`。提供时在操作行渲染
+   「问细节」文本按钮（弱化样式，位于忽略左侧）。按钮在选项 radiogroup 之外，
+   选项数字快捷键与 roving-tabindex 导航不受影响。提交进行中时按钮禁用。
+2. App 只为主视图 overlay 接线该回调，门控与 `/btw side` 相同
+   （`sideTasksAvailable`）。回调用 `formatAskUserQuestions(rawInput)` 格式化
+   待答载荷——语言中立的编号问题快照，含选项 label/description——然后调用
+   `createSideTask(t('askUser.detailsPrompt', { questions }))`。
+3. 本地化提示词模板要求侧边任务：先阅读相关代码与上下文；未核实的结论要标注；
+   解释每个问题的背景与每个选项的含义、差异、影响与风险；给出建议并说明理由；
+   不替用户作答、不改动主会话；用 ASD-STE100 句式规则（一句一个意思、主动
+   语态、短句、同一概念一个词、条件在动作前、三项以上用列表、不用比喻和感叹号）
+   写出自包含单文件 HTML（内联 CSS、不引用外部资源），保存到 `.qwen/tmp/` 下；
+   代码、命令、路径、配置键名原样保留；完成后回复文件路径和一句话摘要。
+4. HTML 文件作为回合产物出现在侧边任务聊天中，用现有右侧面板 HTML 预览打开。
+   待答问题保持待答；用户回到主视图作答或忽略。
+
+## 设计决策
+
+- **用侧边任务，不用轻量 btw。** 细节对话可能需要读代码、写文件与多轮追问；
+  侧边任务是继承上下文的完整子会话，而 `btwSessionStream` 是单发回答。HTML
+  交付也需要文件工具。
+- **预填提示词，不是空草稿。** 点击时用户意图（「解释这个待答问题」）已知；
+  预填省去一次输入并锁定范围。用户仍可用后续提示词引导。
+- **样式规则写进提示词。** 侧边任务模型不共享用户的个人记忆，受控语言与 HTML
+  要求必须在提示词中自包含。只包含核心句式规则；更重的校验仪式不进入产品
+  默认提示词。
+- **可选 prop，条件渲染。** 没有侧边任务界面的宿主（嵌入式宿主、split 面板、
+  无该能力的 daemon）不传回调，按钮就不存在。不做禁用态 UI。
+- **解释语言跟随 UI 语言。** 提示词模板本地化（en/zh-CN；ru 经现有 i18n 回退
+  机制落到 en），解释语言跟随 UI 语言，而不是 daemon 的输出语言设置。
+- **每个待答问题一个细节任务。** 细节 tab 用权限请求 id（uuid；tab 已按父会话
+  分桶）派生的稳定 id，按 upsert 而非追加：重复点击聚焦已有 tab，不会重复创建
+  子会话。「问题→子会话」关联还按父会话持久化（localStorage），因此比 tab 更
+  长寿：关闭细节 tab 后再点击会重新打开同一子会话；从侧边任务目录以
+  `side-task:<sessionId>` tab 重新打开的子会话会被聚焦而非重复。四个生命周期
+  边界均有覆盖：草稿 tab 在创建 resolve 前关闭时关联仍会记录（父会话身份在创建
+  发起时捕获，服务端不会因关 tab 取消创建）；重开的 tab 保留解释提示词，面板的
+  空会话守卫只在子会话尚无用户提示词时发送（仅图片/文件/资源链接的消息也算——
+  它们以空文本提交），因此被关 tab 打断的提示词恰好送达一次、绝不重发；目录重开
+  的 tab 自身不带提示词，再次点击问细节会先把待发送的提示词补到匹配的 tab 上再聚焦，
+  由同一守卫送达仍然为空的子会话；归档子会话会失效其关联——daemon 的 load
+  路由拒绝归档会话（409 `session_archived`），
+  下次点击会新建子会话而不是附着无法加载的旧会话。归档可能来自任何入口（侧边任务
+  面板、侧栏会话行、概览面板、activity 目录）或另一个浏览器标签，因此绑定在读取侧
+  校验：点击时确认子会话仍在父会话的活跃侧边任务列表中，否则遗忘它，而不是直接信任
+  持久化的 id。当开着的同 id tab 绑定的子会话与校验后的绑定不一致（例如从另一浏览器
+  标签的副本恢复的 tab）时，upsert 会替换它，使面板附着活跃子会话而非保留无法加载的
+  旧面板。每个父会话一条关联，新问题取代已解决问题的关联，存储有界；重记某个
+  父会话会把它移到最新的键槽，使按最旧优先的淘汰不会丢掉仍在频繁使用的父会话。
+  tab id 必须短——
+  面板派生的 daemon clientId 形如 `side-task:<parentSessionId>:<tabId>`，daemon 拒绝超过
+  128 字符的 clientId；App 级测试用 uuid 长度输入经真实派生钉住该预算。
+  `/btw side` 保持每次调用唯一的草稿 id。
+- **子会话以问题命名。** 解释提示词以问题快照开头，因此面板通用的首提示命名（前 200
+  个码点）在 tab 条与侧边任务目录里得到由问题派生的标题，而不是每个细节任务都相同的
+  指令 boilerplate。
+- **快照携带选择语义。** 多选问题标记 `[multiSelect]`，让解释覆盖可组合的
+  选项，而不只依赖继承的转录。
+- **操作行可换行。** 第五个按钮可能把行撑出窄视口，而 flex-end 行的溢出发生
+  在左侧——`scrollWidth` 测不到。操作行改为可换行，并用 320px 双问题回归
+  测试断言每个操作按钮都在面板内且可点击。
+
+## 约束与风险
+
+- 侧边任务在创建时继承父会话转录；待答问题属于该上下文，提示词又内嵌了快照，
+  即使父转录很长，解释也能保持聚焦。
+- `.qwen/tmp/` 是 agent 的临时目录（本仓库 git 忽略）。在未忽略它的工作区里，
+  该文件也只是用户可删除的普通工作区文件；不会自动提交任何内容。
+- 按钮不得破坏面板的键盘契约：它位于操作行，不是选项，不注册数字快捷键。
+- 侧边任务创建可能失败（daemon 错误、策略翻转）。失败处理沿用现有 `/btw side`
+  路径（toast、tab 守卫）；问细节入口不引入新的失败模式。
+
+## 验证计划
+
+- 单元：`formatAskUserQuestions` 的格式化、去空白、跳过畸形条目
+  （`askUserPermission.test.ts`）。
+- 单元：无回调时按钮隐藏；点击触发回调且不提交；按钮在选项组与数字快捷键之外；
+  提交进行中禁用（`AskUserQuestion.test.tsx`）。
+- 单元：App 接线——有 `session_side_task` 时，待答问题的问细节动作创建侧边
+  任务 tab，其 `initialPrompt` 含问题文本、STE100 指令与 `.qwen/tmp/` 目标；
+  主会话无 `submitPermission`/`sendPrompt`；无该能力时不提供回调
+  （`App.test.tsx`）。
+- 视觉：`client/e2e/visuals/ask-user-details.spec.ts`（mock daemon、真实
+  Chromium、dark/light、zh-CN UI）——按钮在待答面板渲染，点击打开侧边任务
+  tab，问题保持待答。
+- E2E：`.qwen/e2e-tests/` —— 真实 daemon、待答 AskUser、点击问细节，
+  验证侧边任务创建、HTML 产物预览，以及主问题保持待答。2026-11-06 已用真实
+  daemon 与模型执行，全部通过（证据：`.qwen/e2e-tests/ask-details-e2e-20261106/`）。
+
+## 验收标准
+
+- 有侧边任务能力时，待答 AskUser 面板显示「问细节」；点击后打开侧边任务并
+  开始解释问题，主会话不提交任何答案。
+- 无该能力（或嵌入式/split 界面）时，面板保持不变。
+- 现有 AskUser 键盘行为（数字、方向键、Enter、Esc、Ctrl+Enter）不变。

+# Reclaim Idle Channel Sessions
+
+[English](channel-session-idle-reclaim.md) | [简体中文](channel-session-idle-reclaim.zh-CN.md)
+
+**Status:** Implemented
+**Date:** 2026-11-07
+**Scope:** `packages/acp-bridge/src/session-control-plane.ts`,
+`packages/web-shell/client/**`
+
+## 1. Problem
+
+A workspace can reach `maxSessionsPerWorkspace` while every live session is
+idle. The daemon then rejects every new session with HTTP 503 and
+`code: "session_limit_exceeded"` until an operator closes sessions manually.
+
+On a long-running daemon this is routine, not exceptional: each GitHub channel
+event creates a route-scoped session, and the channel bridge keeps an SSE event
+pump attached to it. The existing idle reaper refuses to close any session with
+`events.subscriberCount > 0`, so the pump pins the session forever. `qwen-code`
+reached 64/64 this way on 2026-11-07; all 64 sessions were idle channel
+sessions and the user could not create a new one.
+
+## 2. Current Behavior
+
+- `entryIsAutoCloseCandidate` returns false for every session with a live SSE
+  subscriber, regardless of who owns the subscription.
+- The channel bridge starts one event pump per cached session and keeps it open
+  after the turn settles.
+- The reaper therefore never sees a channel session as reaped, and the
+  per-workspace cap is consumed until the daemon restarts.
+- The release dialog already exists (`/release`), but it is only reachable by
+  typing the command and releases one session at a time.
+
+## 3. Goals
+
+- Reclaim an idle channel session even while its channel-owned SSE pump is
+  attached.
+- Never close a session that has local work or that the child reports as held.
+- Preserve the strict SSE-subscriber guard for user-owned sessions.
+- Give the user a visible recovery path when the limit is still reached.
+
+## 4. Non-goals
+
+- LRU eviction at the `maxSessions` boundary. This design does not change
+  admission; a full workspace still returns 503 when no session is reapable.
+- Changing channel route retention or adding per-channel session caps.
+- Releasing sessions while a turn, background task, or pending interaction is
+  active.
+
+## 5. Design
+
+### 5.1 Reaper exception for channel sessions
+
+`entryIsAutoCloseCandidate` gains an internal option:
+
+```ts
+entryIsAutoCloseCandidate(entry, { allowChannelSubscribers: true });
+```
+
+The subscriber guard becomes:
+
+```ts
+if (
+  entry.events.subscriberCount > 0 &&
+  !(opts?.allowChannelSubscribers === true && entry.sourceType === 'channel')
+) {
+  return false;
+}
+```
+
+Only the session reaper passes `allowChannelSubscribers: true`. The
+detach-close path keeps the original guard, so a user-owned session that still
+has another subscriber is not closed by a partial detach.
+
+All other guards remain unchanged:
+
+- `entryCanStartConditionalClose` still rejects active prompts, local work,
+  restores in flight, and incomplete active-work reporting.
+- `childReportsHeldWork` and the child's own conditional-close probe still
+  decide whether the child holds work.
+- The idle TTL still starts from `sessionLastSeenAt`, so a channel session that
+  keeps receiving turns is not reaped.
+
+When the reaper closes a channel session, the channel pump receives the
+terminal event and drops its binding. The next message for that route calls
+`loadOrReplaceSession`, which reloads the transcript or creates a replacement.
+
+### 5.2 Visible recovery path
+
+`dispatchActionError` now carries `session_limit_exceeded` as the notice code
+for a workspace create failure. The Web Shell observes that notice and renders
+a banner above the composer with a "Release idle sessions" button. The button
+opens the existing `ReleaseSessionDialog` for the locked workspace.
+
+The dialog releases through the current session's client when one exists, and
+falls back to the workspace daemon client when it does not. That fallback is
+required because the banner is most useful on the empty new-session screen,
+where no session client has been created yet.
+
+The banner is cleared when the session or workspace changes, or when the user
+dismisses it. This path is a fallback for the remaining 503 cases (for example,
+every slot is held by active work); it does not replace automatic reclamation.
+
+## 6. Rejected Alternatives
+
+| Alternative                                 | Reason not chosen                                                                  |
+| ------------------------------------------- | ---------------------------------------------------------------------------------- |
+| Raise `maxSessions`                         | Delays the failure and increases per-workspace memory.                             |
+| LRU eviction at admission                   | Broader behavior change; still listed as a P1 follow-up in the idle-reaper design. |
+| Channel-side idle TTL                       | Requires a new cross-package bridge close method and per-channel configuration.    |
+| Always ignore SSE subscribers in the reaper | Would close user sessions with an open tab, which is not acceptable.               |
+
+## 7. Risks and Mitigations
+
+| Risk                                                           | Mitigation                                                                         |
+| -------------------------------------------------------------- | ---------------------------------------------------------------------------------- |
+| Channel session closes while waiting for a permission answer   | The child's hold probe refuses the close while work is held.                       |
+| Follow-up message loses conversation context                   | `loadOrReplaceSession` reloads the persisted transcript, or creates a new session. |
+| User-owned session is reaped by the new branch                 | The exception is gated on `sourceType === 'channel'`; control test pins it.        |
+| A user opens a channel session in Web Shell and leaves it idle | The session closes and its transcript stays; reopening reloads it.                 |
+| Reaper closes a channel session mid-turn                       | `entryCanStartConditionalClose` rejects active prompts before the probe.           |
+
+## 8. Validation
+
+- `packages/acp-bridge/src/bridge.test.ts`:
+  - reaps an idle channel session while its channel subscriber is attached;
+  - keeps a non-channel session with an attached subscriber past the TTL.
+- `packages/web-shell/client/daemon/session/httpErrors.test.ts`: classifies
+  `session_limit_exceeded` and rejects unrelated 503 bodies.
+- `packages/web-shell/client/daemon/session/actions.test.ts`: a create failure
+  publishes a `create_session` notice with code `session_limit_exceeded`; a
+  release from the empty new-session screen uses the workspace daemon client.
+- `packages/web-shell/client/components/SessionLimitBanner.test.tsx`: the
+  banner exposes release and dismiss actions.
+- Manual browser run on the built Web Shell against a daemon with
+  `--max-sessions 1`: submit a prompt, confirm the banner, open the release
+  dialog, release the idle session, and create a session successfully.
+
+## 9. Acceptance Criteria
+
+1. A channel session idle past `sessionIdleTimeoutMs` is closed even when its
+   channel event pump is subscribed.
+2. A non-channel session with a live subscriber is not closed by the reaper.
+3. A create rejected by the workspace cap produces a visible release action.
+4. Releasing an idle session frees a slot and the next create succeeds.
+5. Existing reaper tests and web-shell type checks pass.
+
+## 10. Follow-ups
+
+- Implement LRU eviction at the `maxSessions` boundary so a full workspace can
+  reclaim an idle session instead of returning 503 (tracked in
+  `docs/design/session-idle-reaper/README.md` as P1).
+- Consider a per-channel retention policy if channel session volume grows
+  beyond the shared idle TTL.

+# 回收空闲渠道会话
+
+[English](channel-session-idle-reclaim.md) | [简体中文](channel-session-idle-reclaim.zh-CN.md)
+
+**状态：** 已实现
+**日期：** 2026-11-07
+**范围：** `packages/acp-bridge/src/session-control-plane.ts`、
+`packages/web-shell/client/**`
+
+## 1. 问题
+
+一个工作区可能在所有 live 会话都空闲时达到 `maxSessionsPerWorkspace`。此时
+daemon 会对每个新会话返回 HTTP 503 和 `code: "session_limit_exceeded"`，直到
+操作者手动关闭会话。
+
+在长时间运行的 daemon 上这不是异常，而是常态：每个 GitHub 渠道事件都会创建一条
+按 route 隔离的会话，渠道 bridge 会为它保持一个 SSE 事件泵。现有 idle reaper
+拒绝关闭任何 `events.subscriberCount > 0` 的会话，于是这个事件泵会把会话永久钉住。
+2026-11-07 `qwen-code` 就这样达到了 64/64；64 条全是空闲渠道会话，用户无法再创建
+新会话。
+
+## 2. 当前行为
+
+- 对任何带有 live SSE 订阅者的会话，`entryIsAutoCloseCandidate` 都返回 false，
+  不区分订阅者属于谁。
+- 渠道 bridge 为每条缓存会话启动一个事件泵，并在 turn 结束后继续保留。
+- 因此 reaper 永远看不到可回收的渠道会话，每个工作区的名额一直被执行到 daemon
+  重启才释放。
+- 释放对话框能力已经存在（`/release`），但只能通过输入命令打开，而且一次只能
+  释放一条会话。
+
+## 3. 目标
+
+- 即使渠道自己持有的 SSE 事件泵仍挂着，也能回收空闲的渠道会话。
+- 绝不关闭有本地工作、或被 child 报告为持有的会话。
+- 对用户会话保留严格的 SSE 订阅者保护。
+- 当上限仍然被触及时，给用户一个可见的恢复入口。
+
+## 4. 非目标
+
+- 在 `maxSessions` 边界做 LRU 驱逐。本设计不改准入；没有可回收会话时，工作区
+  满仍然返回 503。
+- 修改渠道 route 保留策略，或新增按渠道的会话上限。
+- 在 turn、后台任务或待答交互仍活跃时释放会话。
+
+## 5. 设计
+
+### 5.1 渠道会话的 reaper 例外
+
+`entryIsAutoCloseCandidate` 增加一个内部选项：
+
+```ts
+entryIsAutoCloseCandidate(entry, { allowChannelSubscribers: true });
+```
+
+订阅者保护改为：
+
+```ts
+if (
+  entry.events.subscriberCount > 0 &&
+  !(opts?.allowChannelSubscribers === true && entry.sourceType === 'channel')
+) {
+  return false;
+}
+```
+
+只有会话 reaper 传入 `allowChannelSubscribers: true`。detach 关闭路径保留原
+保护，因此仍有其他订阅者的用户会话不会因为一次部分 detach 被关闭。
+
+其他保护全部不变：
+
+- `entryCanStartConditionalClose` 仍会拒绝活跃 prompt、本地工作、进行中的
+  restore，以及 active-work 上报不完整的 child。
+- `childReportsHeldWork` 和 child 自己的条件关闭探针仍决定 child 是否持有工作。
+- idle TTL 仍从 `sessionLastSeenAt` 起算，因此持续收到 turn 的渠道会话不会被回收。
+

+
+### 5.2 可见的恢复入口

+作为 notice code 带出。Web Shell 观察到该 notice 后，在输入框上方渲染一个横幅，
+提供「释放空闲会话」按钮。按钮会为当前锁定的工作区打开已有的
+`ReleaseSessionDialog`。
+
+对话框在有当前会话客户端时走该客户端释放；没有时回退到工作区 daemon
+客户端。这个回退是必要的：横幅最常出现在空白的新会话页，此时还没有创建任何
+会话客户端。
+
+会话或工作区变化、或用户关闭横幅时，横幅清除。这条路径只作为剩余 503 场景的
+兜底（例如所有名额都被活跃工作占用），不替代自动回收。

+# GitHub Channel: Watch Coverage and Non-Blocking Task Execution
+
+[English](github-channel-watch-coverage-async-tasks.md) | [简体中文](github-channel-watch-coverage-async-tasks.zh-CN.md)
+
+Status: implemented and verified (2026-11-06); see
+`.qwen/e2e-tests/github-channel-watch-coverage-async-tasks.md` for the
+baseline dry-run, the local-build E2E results, and the mutation witnesses.
+
+## Problem statement
+
+The GitHub channel's bound-session delivery (`deliverToBoundSessions` +
+`prWatchEvents`) is unreliable on a daemon with many PR bindings. Two
+independent defects, both observed live on a production daemon running
+0.26.8 with 315 session bindings (242 active watch candidates, ~94 open-PR
+bindings):
+
+1. **Watch starvation.** The PR state watch polls at most
+   `MAX_WATCHED_PRS = 30` bound PRs per pass, selected purely by binding
+   `updatedAt` recency (`GithubAdapter.ts`, `runPrStateWatch`). Every other
+   bound PR is never polled, so `head_change` / `ci_failure` /
+   `merge_conflict` / `state_change` events for it are never detected. The
+   daemon logs `PR watch cap exceeded: watching 30/242 bound PRs` on every
+   poll. Two effects compound:
+   - Open PRs with older bindings are crowded out by newer bindings,
+     including bindings of PRs that are already merged.
+   - A PR whose binding records `merged`/`closed` stays in the active set
+     until the watch itself observes the terminal transition. If the cap
+     excludes it, that observation never happens, so it occupies an active
+     slot forever. The active set grows monotonically with dead PRs.
+2. **Head-of-line blocking.** The poll loop is serial
+   (`PollingChannelBase.runLoop` awaits `pollOnce`). Inside `pollOnce`,
+   both fresh dispatch (`dispatchEnvelope` public branch) and recovery
+   (`recoverInboundTasks`) await `runInboundTask`, whose public path
+   (`handleInbound`) awaits the **entire agent turn** before the reply is
+   published. A single `review_requested` on an unbound PR therefore
+   freezes the whole channel — watch pass, bound deliveries, and every
+   other notification — for the full turn duration (observed: 64 minutes).
+   Bound delivery itself is fast (a prompt POST that does not wait for the
+   turn); only the public path blocks.
+
+## Goals
+
+- Every open bound PR is watched whenever the configured watch budget
+  allows it; terminal-pending PRs drain out of the active set instead of
+  accumulating.
+- The watch budget is operator-configurable within documented rate-limit
+  trade-offs.
+- A long public-path agent turn never blocks the poll loop: watch
+  detection, bound delivery, and intake of new notifications continue
+  while the turn runs.
+- No change to delivery guarantees: at-least-once, durable claims before
+  cursor advance, edge-triggered watch semantics, crash recovery, and
+  backpressure budgets all behave exactly as today.
+
+## Non-goals
+
+- Parallel public turns (concurrency stays 1; ordering is preserved).
+- Changing the notification-cursor contract: recoverable non-backpressure
+  tasks still hold mark-as-read (`hasCursorBlockingTasks`), as today.
+- Raising GitHub rate limits or adding conditional-request caching.
+- Any change to bound-session delivery itself (fan-out, roles, templates).
+
+## Proposed changes
+
+### 1. Watch selection and budget (`packages/channels/github`)
+
+- New channel config field `prWatchLimit`:
+  - Descriptor: `kind: 'number'`, `exclusiveMinimum: 0`, `maximum` and
+    `default` built from the adapter's exported `MAX_PR_WATCH_LIMIT` (500)
+    and `DEFAULT_PR_WATCH_LIMIT` (30) so the form bound and the effective
+    bound cannot drift; the description states the rate arithmetic (~60
+    requests/hour per watched PR at the 60 s default; a 5000/hour PAT
+    budget admits ~80 watched PRs, ~69 open while a terminal backlog
+    drains at the 1.2x fan-out; over budget, every watch pass aborts).
+  - Adapter: a `prWatchLimit` getter clamps like the existing
+    `pollInterval` getter (invalid/unset → 30; fractional → rounded up;
+    above 500 → clamped to 500). Hand-edited settings reach the getter
+    unchecked by the descriptor, so the clamp is load-bearing and tested.
+  - Validation: `validateBoundSessionConfig` rejects `prWatchLimit`
+    without `deliverToBoundSessions: true`, with the sibling wording.
+  - Web Shell: the field is registered in the editor's GitHub label map
+    and bound-session panel, with both locale catalogues translated.
+- `runPrStateWatch` partitions the active set:
+  - **open**: binding state is neither `merged` nor `closed`, and the
+    watch entry has not observed `prState === 'closed'` (a stale-open
+    registry must not let an observed-closed PR hold an open-tier slot);
+  - **terminal-pending**: everything else that still needs its terminal
+    observation.
+    Open PRs take the FULL budget (by `updatedAt` desc). Terminal-pending
+    PRs drain in an ADDITIONAL slice outside it —
+    `min(terminalCount, max(1, ceil(limit * 0.2)))`, plus any leftover
+    open budget. Without the slice, `limit == openCount` would starve the
+    drain forever and the active set would grow with every merge. An
+    IN-budget reservation was tried and removed: it excludes up to
+    `ceil(limit * 0.2)` open bindings while the backlog drains, and an
+    edge event on an excluded binding inside that window is swallowed
+    permanently — the very defect this design fixes. The additional
+    slice costs at most `ceil(limit * 0.2)` extra `pulls.get` per poll
+    during the drain; each drained binding leaves the active set for
+    good, so the fan-out returns to the open budget once the backlog
+    clears.
+- The cap warning keeps the `PR watch cap exceeded` prefix (pinned by
+  tests) and fires whenever the selection cannot cover the whole active
+  set: it reports `watched/active` counts (watched may exceed the open
+  limit while the terminal slice drains), the configured open limit, and
+  the excluded keys (open and terminal-pending alike).
+- Terminal observation stays API-authoritative: no `state_change` is ever
+  synthesized from binding registry data. The registry and the watch
+  entry only decide _priority_, never event content. A genuinely reopened
+  PR gets one leftover-budget observation and returns to the open tier.
+
+### 2. Background public-task runner (`packages/channels/github`)
+
+- A per-channel FIFO runner (concurrency 1) owns public-path
+  `runInboundTask` execution. It follows the existing
+  `retryPendingFinalDeliveries` background-loop pattern: started on
+  demand, retired by generation on `disconnect`/`connect`.
+- `dispatchEnvelope` public branch: claim the task durably (unchanged),
+  run the absence gate synchronously, then enqueue and return `true`.
+  The absence gate (incomplete binding snapshot cannot prove a PR is
+  unbound) must run at dispatch so a deferred event keeps the `false`
+  verdict the comment lane's first-contact body suppression depends on;
+  `runInboundTask` re-checks it for tasks recovery enqueues.
+- Gone-session public fallbacks (bound target vanished, absence
+  authoritative) clear the delivery durably and requeue through the same
+  runner (`requeued` verdict) instead of awaiting `handleInbound` in the
+  poll lane: they are full public turns, and running them inline both
+  head-of-line-blocks the poll and can steer-cancel another public turn
+  on a shared channel session.
+- Bound fan-out branch stays inline: delivery is a fast prompt POST whose
+  verdict (delivered/deferred/retired) the dispatch return value and the
+  cursor gate already depend on.
+- `recoverInboundTasks` skips tasks in the runner's in-flight set BEFORE
+  any branch mutates them (the retarget branch would otherwise re-resolve
+  a backpressure-parked task whose public turn is running — the running
+  transition merges patches, so `backpressure: true` survives — and
+  deliver it bound a second time). A running task with no in-flight entry
+  is a genuine crash and is still recovered and charged. Bound tasks run
+  inline as today; other recoverable tasks are enqueued.
+- An in-flight set (queued + running task ids) prevents double execution
+  when a recovery pass re-scans a queued task. On a same-instance
+  reconnect, the id the orphaned runner is still executing stays in the
+  set (the orphan's `finally` removes it); queued-but-unstarted ids are
+  dropped and re-enqueued by recovery from the durable store.
+- The runner isolates failures: `runInboundTask` already transitions
+  errors to `failed`/backpressure/retirement; an unexpected throw is
+  logged AND journaled as an inbound `failed` row once per task id (the
+  poll loop's per-thread catch no longer sees it), then the runner
+  continues with the next task.
+- `disconnect` retires the runner generation and resolves idle waiters.
+  The winding-down runner's restart hook only fires for the CURRENT
+  generation, so a retired queue is never drained after disconnect; the
+  tasks stay durable for the next connect's recovery. An in-flight turn
+  keeps today's semantics: the worker exits, the daemon session survives.
+- While a thread's in-flight public work held the cursor at poll start,
+  the comment/aggregate lanes skip re-fetching its comments and the
+  direct lane skips re-processing (snapshot, not live: a task claimed
+  during this poll must not suppress the same thread's later lanes, and
+  a crashed task that is not in flight must stay re-dispatchable). The
+  first-contact body feed is NOT gated: it claims once and the runner
+  serializes it behind any running comment turn. A deferral gate was
+  tried and removed — nothing reserves a deferred body, and the
+  end-of-poll cursor commit can mark the thread read once the blocking
+  task settles, after which first contact (`!lastReadAt`) is unreachable
+  and the body is lost permanently.
+
+### Invariants preserved (why this is safe)
+
+- Claims are durable before the dispatch return, so cursor advance never
+  outruns consumption — unchanged.
+- `hasCursorBlockingTasks` still freezes mark-as-read while a public task
+  is recoverable; polls during a long turn re-list the same window and
+  dedupe skips already-claimed events, exactly the state crash recovery
+  already produces today.
+- Public tasks execute serially in claim order (FIFO, concurrency 1), so
+  per-thread reply ordering is unchanged.
+- Watch pending/fired reconciliation, attempt budgets, backpressure
+  horizons, and the publication audit are untouched.
+
+## Files affected
+
+- `packages/channels/github/src/GithubAdapter.ts` — selection, limit
+  getter, runner, dispatch/recovery hand-off, absence gate extraction,
+  gone-session requeue, held-thread fetch skip, disconnect/connect.
+- `packages/channels/github/src/index.ts` — `prWatchLimit` descriptor
+  field built from the exported constants.
+- `packages/channels/github/src/GithubAdapter.test.ts` — new coverage;
+  the `pollOnce` test helpers additionally await runner idle so existing
+  public-path assertions keep their meaning.
+- `packages/web-shell/client/components/channels/ChannelEditorDialog.tsx`
+  and `packages/web-shell/client/i18n.tsx` — field registration and both
+  locale catalogues.
+- Docs: the GitHub channel guide's bound-session section gains the
+  `prWatchLimit` knob and the non-blocking execution note.
+
+## Design decisions and rationale
+
+1. **Open-first priority with an additional terminal slice.** A larger
+   hard cap only postpones starvation and spends rate budget on dead
+   PRs. Priority fixes the ordering defect; the additional slice (20% of
+   the limit, at least one, OUTSIDE the open budget) guarantees the drain
+   progresses even when open PRs fill the limit without excluding a
+   single open binding, and disappears once the backlog clears. The
+   in-budget variant was measured to re-starve the oldest open bindings
+   for the whole drain window (verification fixture: 30 open + 5
+   terminal at limit 30 must still deliver the oldest open PR's head
+   change), so the slice is additive and the worst-case fan-out is
+   bounded at the limit plus `ceil(limit * 0.2)` (1.2x at the default
+   30).
+2. **Configurable limit, default unchanged (30).** Each watched PR costs
+   roughly one `pulls.get` per poll plus conditional Checks fetches —
+   ~60 requests/hour at the 60 s default, so a 5000 req/h PAT budget
+   admits ~80 watched PRs (~69 open while a terminal backlog drains at
+   the 1.2x fan-out). Operators with more open bindings raise
+   `prWatchLimit` (and `pollInterval`) deliberately. The watch pass
+   already fails fast on rate limits, so an over-budget configuration
+   degrades instead of hammering the API; the arithmetic is stated in
+   the descriptor and the guide.
+3. **Concurrency 1 runner, not per-session parallelism.** The defect is
+   liveness, not throughput. Serial execution preserves reply ordering
+   and avoids bridge-level concurrent-prompt hazards documented in
+   `ChannelBase` (steer/chain-and-wait). Every transition into public
+   execution goes through the runner, including gone-session fallbacks.
+4. **No binding-state shortcut for terminal observation.** Synthesizing
+   `state_change` from registry data would break the edge-triggered
+   contract (the registry can lag or lead the API). One real observation
+   per terminal PR is cheap and drains the set permanently. The watch
+   entry may tier a stale-open binding as terminal, never fabricate an
+   event.
+5. **No first-contact body deferral gate.** A deferred body is not
+   reserved by anything: once the blocking task settles, the end-of-poll
+   cursor commit can mark the thread read, and first contact
+   (`!lastReadAt`) becomes unreachable — permanent loss. The runner's
+   FIFO already serializes the body turn behind any running comment
+   turn, which is the property the gate was meant to protect. The
+   synchronous absence gate at dispatch preserves the lane's
+   false-verdict body suppression for backpressure-deferred comments.
+
+## Constraints and risks
+
+- **Test migration surface.** Existing tests assert public outcomes
+  immediately after `await pollOnce()`. Centralizing the runner-idle wait
+  in the test helpers keeps most assertions intact; tests that
+  intentionally observe mid-flight state must opt out explicitly.
+- **Frozen-cursor polling cost.** While a long public turn runs, the
+  window re-lists every poll; the held-thread snapshot skips the
+  redundant per-thread comment fetches and direct-lane reprocessing, so
+  the request volume no longer scales with turn duration. Dispatch
+  dedupe is unchanged.
+- **Runner shutdown.** A turn in flight at `disconnect` is not cancelled
+  by this change (same as today); recovery replays it at next start with
+  the existing attempt budget. The retired generation never restarts
+  the queue, and idle waiters resolve at disconnect.
+
+## Validation plan
+
+- Unit tests (collocated): open-first selection with the incident shape;
+  the additional terminal slice at `limit == openCount` (every open
+  binding keeps its observation while the backlog drains, and the oldest
+  open PR's head change inside the drain window is delivered);
+  stale-open tiering; limit clamping (over-ceiling, zero, non-finite) and
+  descriptor acceptance; validation prerequisite; warning shape; runner
+  hand-off,
+  FIFO order, in-flight dedupe via a mid-turn recovery pass, recovery
+  retarget skip, gone-session requeue, same-instance reconnect,
+  disconnect stop + idle waiters, held-thread fetch skip, failure
+  journaling; cursor gate unchanged while a public task runs.
+- E2E (`.qwen/e2e-tests/github-channel-watch-coverage-async-tasks.md`):
+  real daemon + local GitHub-compatible stub + local model endpoint, per
+  the channel real-scenario harness. Baseline dry-run on the installed
+  release must show both defects; the local build must pass all groups.
+- Mutation witnesses: revert open-first ordering, revert the enqueue
+  hand-off, remove the recovery in-flight skip, remove the additional
+  terminal slice, shrink the open budget by the slice (the removed
+  in-budget reservation), remove the disconnect generation guard — each
+  must turn a dedicated test red.
+
+## Acceptance criteria
+
+- With >30 open bound PRs and default limit, the most recent open PRs
+  are watched within the FULL open budget and terminal-pending PRs drain
+  through the additional slice outside it; with `prWatchLimit` raised to
+  the open count, every open bound PR receives `head_change` delivery.
+- Terminal-pending PRs leave the active set after one observed poll,
+  even when open PRs fill the limit, without excluding any open binding
+  (fixture: 30 open + 5 newer terminal at limit 30 — the oldest open PR
+  is observed and its head change is delivered); the active count in the
+  cap warning shrinks accordingly.
+- While a public review turn runs for minutes, a bound PR's head change
+  is still delivered within one poll interval, new notifications are
+  still claimed, and the held thread's comments are not re-fetched every
+  poll.
+- A first-contact body is never lost to a cursor commit; a deferred
+  (backpressure) comment still suppresses the body for that poll.
+- All existing delivery/recovery/backpressure tests pass (helpers await
+  runner idle); lint, typecheck, and focused unit suites green.
+
+## Open questions
+
+- None blocking. A future enhancement could batch the PR state queries
+  to remove the per-PR fan-out entirely (raised in triage as the
+  preferred long-term shape); it is separate work with its own
+  rate-limit questions and is deliberately deferred.

+# GitHub 渠道：watch 覆盖与非阻塞任务执行
+
+[English](github-channel-watch-coverage-async-tasks.md) | [简体中文](github-channel-watch-coverage-async-tasks.zh-CN.md)
+
+状态：已实现并验证（2026-11-06 提案，2026-11-07 评审修复轮）；基线干跑、
+本地构建 E2E 结果与变异见证见
+`.qwen/e2e-tests/github-channel-watch-coverage-async-tasks.md`。
+
+## 问题陈述
+
+在绑定数量较多的 daemon 上，GitHub 渠道的绑定会话投递
+（`deliverToBoundSessions` + `prWatchEvents`）不可靠。两个相互独立的缺陷，
+均在一台运行 0.26.8 的生产 daemon 上实盘观测到（315 条会话绑定、242 个
+活跃 watch 候选、约 94 条 open PR 绑定）：
+
+1. **watch 饥饿。** PR 状态 watch 每轮至多轮询
+   `MAX_WATCHED_PRS = 30` 个绑定 PR，且纯按绑定 `updatedAt` 新旧选择
+   （`GithubAdapter.ts` 的 `runPrStateWatch`）。其余绑定 PR 永不被轮询，
+   它们的 `head_change` / `ci_failure` / `merge_conflict` / `state_change`
+   事件永不被检测。daemon 每轮日志都警告
+   `PR watch cap exceeded: watching 30/242 bound PRs`。两个效应叠加：
+   - 绑定较早的 open PR 被更新的绑定挤出，其中不少是早已合入的 PR 的绑定。
+   - 绑定里记录为 `merged`/`closed` 的 PR 会一直留在活跃集里，直到 watch
+     亲自观测到终态迁移。若上限把它排除在外，这次观测永远不会发生，
+     于是它永久占据一个活跃名额。活跃集随死 PR 单调增长。
+2. **队头阻塞。** 轮询循环是串行的
+   （`PollingChannelBase.runLoop` await `pollOnce`）。在 `pollOnce` 内部，
+   新派发（`dispatchEnvelope` 公共分支）与恢复（`recoverInboundTasks`）
+   都 await `runInboundTask`，其公共路径（`handleInbound`）会等待
+   **整个 agent turn** 跑完才发布回复。于是一个落在未绑定 PR 上的
+   `review_requested` 就把整个渠道——watch、绑定投递、所有其他通知——
+   冻结整个 turn 时长（实测 64 分钟）。绑定投递本身很快（一次不等 turn
+   的 prompt POST）；只有公共路径阻塞。
+
+## 目标
+
+- 只要配置的 watch 预算允许，每个 open 绑定 PR 都被 watch；终态待观测
+  PR 从活跃集中排出，而不是不断累积。
+- watch 预算可由运维配置，并写明限流权衡。
+- 冗长的公共路径 agent turn 永不阻塞轮询循环：turn 运行期间，watch
+  检测、绑定投递、新通知接收照常进行。
+- 不改变投递保证：至少一次、游标推进前先持久化认领、边沿触发的 watch
+  语义、崩溃恢复、背压预算，全部与今天一致。
+
+## 非目标
+
+- 公共 turn 并行化（并发度保持 1，顺序不变）。
+- 改变通知游标契约：可恢复的非背压任务仍然持有 mark-as-read
+  （`hasCursorBlockingTasks`），与今天一致。
+- 提升 GitHub 限流额度或引入条件请求缓存。
+- 改动绑定会话投递本身（fan-out、角色、模板）。
+
+## 提议的改动
+
+### 1. watch 选择与预算（`packages/channels/github`）
+
+- 新渠道配置字段 `prWatchLimit`：
+  - 描述符：`kind: 'number'`、`exclusiveMinimum: 0`，`maximum` 与
+    `default` 取自适配器导出的 `MAX_PR_WATCH_LIMIT`（500）与
+    `DEFAULT_PR_WATCH_LIMIT`（30），表单边界与生效边界不会漂移；
+    描述写明限流算术（默认 60 秒间隔下每个被 watch 的 PR 约 60 次
+    请求/小时；5000 次/小时的 PAT 预算约容纳 80 个被 watch 的 PR，终态
+    积压按 1.2 倍扇出排出时约 69 个 open；超预算会让每轮 watch 都中止）。
+  - 适配器：`prWatchLimit` getter 沿用现有 `pollInterval` getter 的钳制
+    方式（非法/缺省 → 30；小数 → 向上取整；超过 500 → 钳到 500）。
+    手工编辑的设置文件不经过描述符校验直达 getter，因此钳制是承重
+    设计并有测试。
+  - 校验：`validateBoundSessionConfig` 在缺少
+    `deliverToBoundSessions: true` 时拒绝 `prWatchLimit`，措辞与兄弟
+    字段一致。
+  - Web Shell：该字段登记进编辑器的 GitHub 标签映射与绑定会话面板，
+    两份语言词条均已翻译。
+- `runPrStateWatch` 对活跃集分区：
+  - **open**：绑定状态既非 `merged` 也非 `closed`，且 watch 条目尚未
+    观测到 `prState === 'closed'`（陈旧的 open 注册表不能让已观测关闭
+    的 PR 占据 open 档名额）；
+  - **终态待观测**：其余仍需终态观测的条目。
+    open PR 独占**全部**预算（按 `updatedAt` 降序）。终态待观测 PR 在
+    预算之外的一块**额外**名额中排出——
+    `min(终态数, max(1, ceil(limit * 0.2)))`，外加 open 预算的任何剩余。
+    没有这块名额时，`limit == open 数` 会让排出永远饿死，活跃集随每次
+    合入增长。曾尝试**预算内**预留并移除：它会在积压排出期间排除至多
+    `ceil(limit * 0.2)` 个 open 绑定，窗口内被排除绑定上的边沿事件会被
+    永久吞掉——正是本设计要修的缺陷。额外名额在排出期间每轮至多多花
+    `ceil(limit * 0.2)` 次 `pulls.get`；每个排出的绑定永久离开活跃集，
+    积压清空后扇出即回到 open 预算。
+- 上限警告保留 `PR watch cap exceeded` 前缀（有测试 pin），只要选择覆盖
+  不了整个活跃集就触发：报告 `已watch/活跃` 计数（终态名额排出期间
+  已 watch 数可能超过 open 上限）、配置的 open 上限、以及被排除的键
+  （open 与终态待观测一视同仁）。
+- 终态观测仍以 API 为权威：绝不从绑定注册表数据合成 `state_change`。
+  注册表与 watch 条目只决定**优先级**，从不决定事件内容。真正被重新
+  打开的 PR 会得到一次剩余预算观测并回到 open 档。
+
+### 2. 后台公共任务运行器（`packages/channels/github`）
+
+- 每渠道一个 FIFO 运行器（并发度 1）承接公共路径的 `runInboundTask`
+  执行。沿用现有 `retryPendingFinalDeliveries` 后台循环模式：按需启动，
+  `disconnect`/`connect` 以代次退役。
+- `dispatchEnvelope` 公共分支：持久化认领任务（不变），同步执行缺席
+  闸门，然后入队并返回 `true`。缺席闸门（不完整的绑定快照无法证明 PR
+  无绑定）必须在派发时执行，被延迟的事件才能保持评论车道 first-contact
+  body 抑制所依赖的 `false` 裁决；`runInboundTask` 对恢复入队的任务
+  再检查一次。
+- 绑定会话消失的公共回退（目标消失且缺席已确定为权威）持久化清空
+  delivery 后经同一运行器重新入队（`requeued` 裁决），而不是在轮询车道
+  内 await `handleInbound`：它们是完整的公共 turn，内联执行既会队头
+  阻塞轮询，也可能在共享渠道会话上 steer-cancel 另一个公共 turn。
+- 绑定 fan-out 分支保持内联：投递是一次快速 prompt POST，其裁决
+  （delivered/deferred/retired）是派发返回值与游标闸门已经依赖的输入。
+- `recoverInboundTasks` 在任何分支改动任务**之前**跳过运行器在途集合
+  中的任务（否则重定向分支会重新解析一个公共 turn 正在运行的背压挂起
+  任务——running 转换是合并语义，`backpressure: true` 会保留——并把
+  它第二次绑定投递）。没有在途条目的 running 任务是真正的崩溃，仍然
+  恢复并计次。绑定任务照旧内联执行；其余可恢复任务入队。
+- 在途集合（已入队 + 运行中的任务 id）防止恢复 pass 重扫已入队任务时
+  重复执行。同实例重连时，孤立运行器正在执行的任务 id 保留在集合中
+  （孤立运行器的 `finally` 会移除它）；已入队但未启动的 id 被丢弃，
+  由恢复从持久存储重新入队。
+- 运行器隔离失败：`runInboundTask` 已把错误迁移为
+  `failed`/背压/退役；意外抛出会被记日志**并**按任务 id 各记一次
+  inbound `failed` 事件行（轮询循环的按线程 catch 不再看到它），然后
+  运行器继续下一个任务。
+- `disconnect` 退役运行器代次并释放空闲等待者。收尾运行器的重启钩子
+  只对**当前**代次生效，因此 disconnect 之后绝不会继续排空退役队列；
+  任务保持持久化，等下次 connect 的恢复。在途 turn 保持今天的语义：
+  worker 退出、daemon 会话存活。
+- 当某线程的在途公共工作在轮询开始时已持有游标，评论/聚合车道跳过对
+  它的评论重抓，直接车道跳过重复处理（快照而非实时：本轮认领的任务
+  不能抑制同线程后续车道；不在途的崩溃任务必须仍可重新派发）。
+  first-contact body 投递**不加**闸门：它只认领一次，运行器会把它串行
+  排在任何运行中的评论 turn 之后。曾尝试延迟闸门并移除——没有任何
+  东西为被延迟的 body 占位，一旦阻塞任务落定，轮询末尾的游标提交可能
+  把线程标记已读，此后 first contact（`!lastReadAt`）不可达，body
+  永久丢失。
+
+### 保留的不变量（为什么安全）
+
+- 认领在派发返回前已持久化，游标推进永不超越消费——不变。
+- 公共任务可恢复期间，`hasCursorBlockingTasks` 仍冻结 mark-as-read；
+  长 turn 期间的每轮轮询重列同一窗口，去重跳过已认领事件——这正是今天
+  崩溃恢复已经产生的状态。
+- 公共任务按认领顺序串行执行（FIFO、并发 1），每线程回复顺序不变。
+- watch pending/fired 对账、尝试预算、背压地平线、发布审计均不改动。
+
+## 受影响文件
+
+- `packages/channels/github/src/GithubAdapter.ts` —— 选择逻辑、上限
+  getter、运行器、派发/恢复交接、缺席闸门提取、gone-session 重新入队、
+  持有线程免重抓、disconnect/connect。
+- `packages/channels/github/src/index.ts` —— 由导出常量构建的
+  `prWatchLimit` 描述符字段。
+- `packages/channels/github/src/GithubAdapter.test.ts` —— 新增覆盖；
+  `pollOnce` 测试助手额外等待运行器空闲，使既有公共路径断言含义不变。
+- `packages/web-shell/client/components/channels/ChannelEditorDialog.tsx`
+  与 `packages/web-shell/client/i18n.tsx` —— 字段登记与两份语言词条。
+- 文档：GitHub 渠道指南的绑定会话小节补充 `prWatchLimit` 旋钮与
+  非阻塞执行说明。
+
+## 设计决策与理由
+
+1. **open 优先 + 额外终态名额。** 更大的硬上限只是推迟饥饿，还把限流
+   预算花在死 PR 上。优先级修复排序缺陷；额外名额（上限的 20%，至少
+   一个，在 open 预算**之外**）保证 open 占满上限时排出仍能推进，且不
+   排除任何一个 open 绑定，积压清空后即消失。预算内变体经实测会在整个
+   排出窗口内重新饿死最旧的 open 绑定（验证夹具：limit 30 下 30 open +
+   5 终态，最旧 open PR 的 head 变化仍必须投递），因此名额是加法的，
+   最坏扇出界定为上限加 `ceil(limit * 0.2)`（默认 30 时为 1.2 倍）。
+2. **上限可配置，默认不变（30）。** 每个被 watch 的 PR 每轮约花费一次
+   `pulls.get` 加条件性 Checks 拉取——默认 60 秒间隔下约 60 次请求/小时，
+   5000 次/小时的 PAT 预算约容纳 80 个被 watch 的 PR（终态积压按 1.2 倍
+   扇出排出时约 69 个 open）。绑定更多的运维有意识地调高
+   `prWatchLimit`（与 `pollInterval`）。watch pass 本就在限流时快速失败，
+   超预算配置会降级而不是锤爆 API；算术写明在描述符与指南中。
+3. **并发 1 运行器，而非按会话并行。** 缺陷是活性，不是吞吐。串行执行
+   保住回复顺序，避开 `ChannelBase` 里记载的桥级并发 prompt 风险
+   （steer/chain-and-wait）。所有进入公共执行的转换都经过运行器，包括
+   gone-session 回退。
+4. **终态观测不走绑定状态捷径。** 从注册表数据合成 `state_change` 会
+   破坏边沿触发契约（注册表可能滞后或超前于 API）。每个终态 PR 一次
+   真实观测，成本低且永久排出活跃集。watch 条目可以把陈旧 open 绑定
+   分为终态档，但绝不凭空生成事件。
+5. **不加 first-contact body 延迟闸门。** 被延迟的 body 没有任何占位：
+   阻塞任务一旦落定，轮询末尾的游标提交可能把线程标记已读，first
+   contact（`!lastReadAt`）从此不可达——永久丢失。运行器 FIFO 本就把
+   body turn 串行排在运行中的评论 turn 之后，这正是闸门想保护的性质。
+   派发时的同步缺席闸门保留了车道对背压延迟评论的 false 裁决 body
+   抑制。
+
+## 约束与风险
+
+- **测试迁移面。** 既有测试在 `await pollOnce()` 后立即断言公共结果。
+  把运行器空闲等待集中到测试助手可保住大多数断言；刻意观察在途状态的
+  测试必须显式退出该等待。
+- **冻结游标期的轮询成本。** 长公共 turn 运行期间窗口每轮重列；持有
+  线程快照跳过冗余的按线程评论重抓与直接车道重复处理，请求量不再随
+  turn 时长线性增长。派发去重不变。
+- **运行器关停。** `disconnect` 时不取消在途 turn（与今天一致），恢复
+  机制在下次启动按既有尝试预算重放。退役代次绝不重启队列，空闲等待者
+  在 disconnect 时释放。
+
+## 验证计划
+
+- 单测（同目录）：事故形态的 open 优先选择；`limit == open 数` 时的额外
+  终态名额（积压排出期间每个 open 绑定保住观测，窗口内最旧 open PR 的
+  head 变化仍投递）；陈旧 open 分档；上限钳制（超上限、零、非有限）与
+  描述符接受；校验前置依赖；警告形态；运行器交接、FIFO 顺序、turn 中途
+  恢复 pass 钉住在途去重、恢复重定向跳过、gone-session 重新入队、同实例
+  重连、disconnect 停止 + 空闲等待者、持有线程免重抓、失败记账；公共
+  任务运行期间游标闸门不变。
+- E2E（`.qwen/e2e-tests/github-channel-watch-coverage-async-tasks.md`）：
+  按渠道真场景 harness，用真实 daemon + 本地 GitHub 兼容桩 + 本地模型
+  端点。基线干跑（已安装发行版）必须复现两个缺陷；本地构建必须通过
+  全部组。
+- 变异见证：回退 open 优先排序、回退入队交接、移除恢复在途跳过、移除
+  额外终态名额、把 open 预算缩减该名额（已移除的预算内预留）、移除
+  disconnect 代次守卫——每一项都必须让对应专属测试变红。
+
+## 验收标准
+
+- open 绑定 PR 超过 30 且用默认上限时，最新的 open PR 在**完整** open
+  预算内被 watch，终态待观测 PR 经预算之外的额外名额排出；把
+  `prWatchLimit` 抬到 open 数量后，每个 open 绑定 PR 都能收到
+  `head_change` 投递。
+- 终态待观测 PR 在一次观测轮询后离开活跃集，即使 open PR 占满上限，且
+  不排除任何 open 绑定（夹具：limit 30 下 30 open + 5 个更新的终态——
+  最旧 open PR 被观测、其 head 变化被投递）；上限警告里的活跃数相应
+  下降。
+- 公共评审 turn 运行数分钟期间，绑定 PR 的 head 变化仍在一个轮询间隔
+  内投递，新通知仍被认领，持有线程的评论不再每轮重抓。
+- first-contact body 绝不因游标提交而丢失；被延迟（背压）的评论仍在
+  该轮抑制 body。
+- 既有投递/恢复/背压测试全部通过（助手等待运行器空闲）；lint、
+  typecheck、聚焦单测全绿。
+
+## 开放问题
+
+- 无阻塞项。未来可用批量 PR 状态查询彻底去掉按 PR 扇出（triage 提出的
+  长期优选形态）；那是独立工作，有自己的限流问题，刻意推迟。

+# GitHub Channel Repository Event Filter (Allowlist / Blocklist)
+
+[English](github-repo-filter.md) | [简体中文](github-repo-filter.zh-CN.md)
+
+Status: implemented in this change.
+
+## Problem
+
+The GitHub channel processes notifications from every repository the
+authenticated account can see. The only repository-level control today is
+`groupPolicy: "allowlist"` plus `groups` keys: an operator who wants "everything
+except these noisy repositories" has no way to express it, and an operator who
+wants a simple event filter must understand the access-policy machinery
+(group gates, sender policies, per-repository overrides) to get one.
+
+In the Web Shell editor the repository allowlist lives under "Group Policy →
+Allowlist → Allowed repositories". There is no blocklist, and the access-policy
+framing makes a plain "filter events by repository" task unintuitive.
+
+## Current state
+
+- Inbound events arrive through the notification poll loop in
+  `packages/channels/github/src/GithubAdapter.ts` (`pollOnce`). Each
+  notification's subject URL yields `chatId = owner/repo`; `reasonFilter`
+  already skips notifications there, journals a capped `reason_filter` skip
+  row per poll plus one collapsed count row, and lets the cursor advance.
+- Repository access is gated later, per envelope, by `GroupGate`
+  (`groupPolicy` + `groups`). The editor renders repository rows only for this
+  access path.
+- A second event source, PR state watch (`runPrStateWatch`), serves PRs that a
+  user explicitly bound to a live session. It does not flow through the
+  notification loop.
+- The daemon store (`channel-settings-store.ts`) validates every config key
+  against the plugin descriptor and runs the plugin's synchronous
+  `validateConfig` for cross-field rules. The editor mirrors those rules in
+  `channel-editor-state.ts`; `channel-editor-parity.test.ts` binds the two
+  sides with the plugin's own descriptor.
+
+## Goals
+
+- Filter inbound GitHub events by repository with two explicit modes:
+  allowlist (only listed repositories) and blocklist (all except listed).
+- Make the filter a first-class, self-explanatory pair of fields in the Web
+  Shell editor, with repository-format validation and URL-paste tolerance.
+- Keep the runtime, the save-time validator, and the editor mirror in sync
+  through one shared validation function and a parity table.
+
+## Scope boundaries
+
+- The filter applies to every incoming notification, including notifications
+  about PRs bound to a live session. Only PR state watch events
+  (`runPrStateWatch`) — explicit per-PR subscriptions created by the user in
+  a session — bypass it. The field description states this.
+- `groupPolicy` / `groups` keep their access-control meaning unchanged. The
+  repository filter is an additional intake filter; when both are active the
+  effective set is their intersection.
+- No change to other channels, to `GroupGate`, or to the shared `GroupPolicy`
+  type.
+
+## Proposed solution
+
+### Configuration (GitHub plugin)
+
+Two new flat descriptor fields, placed after `reasonFilter`:
+
+- `repoFilterMode`: enum `off | allowlist | blocklist`, default `off`.
+- `repoFilter`: string-list of `owner/repo` entries.
+
+```json
+{
+  "type": "github",
+  "useLocalGh": true,
+  "groupPolicy": "open",
+  "repoFilterMode": "blocklist",
+  "repoFilter": ["octo/noisy-repo", "octo/archive"]
+}
+```
+
+Flat fields (not one object field) because the Web Shell editor cannot edit
+`object`-kind fields.
+
+### Runtime (`GithubAdapter.ts`)
+
+- `validateRepoFilterConfig(config)` — exported pure function returning a
+  string error or `undefined`. Rules:
+  - `repoFilterMode` absent or `off`: the list is ignored entirely (a stale
+    list never blocks a save or a connect while the filter is off).
+  - `repoFilterMode` set to `allowlist`/`blocklist`: `repoFilter` must be a
+    non-empty array of strings, each matching `^[A-Za-z0-9_.-]+/[A-Za-z0-9_.-]+$`
+    after trim + lowercase. An active allowlist with an empty list would
+    silently drop every event, so it is rejected instead.
+  - Any other mode value is rejected.
+- `normalizeRepoFilter(config, name)` calls the same validator and throws on
+  error; `connect()` stores `{ mode, repos: Set<string> } | null` beside
+  `reasonFilter`.
+- In the poll loop, immediately after `extractFromSubjectUrl` and before
+  `reasonFilter`: allowlist skips repositories not in the set, blocklist skips
+  repositories in the set (case-insensitive). A skipped notification is
+  logged to stderr, emitted as a `repoFilter.skip` debug payload, and
+  journaled as `inbound / skipped / repo_filter` with the same per-poll cap
+  (20 rows) and collapsed count row as `reason_filter`. The cursor advances
+  past filtered notifications exactly as it does for reason-filtered ones.
+- `index.ts` `validateConfig` calls `validateRepoFilterConfig`, so the daemon
+  rejects an invalid combination at save time with the same message the
+  runtime would throw.
+
+### Editor (`web-shell`)
+
+- `channel-editor-state.ts`:
+  - `normalizeRepositoryFilterInput(value, baseUrl)` — splits on commas,
+    trims, strips trailing sentence punctuation a paste can carry, lowercases,
+    shortens GitHub web URLs (`https://github.com/owner/repo`, with optional
+    `.git`, trailing slash, query, fragment, or `/pull/123`-style suffix) to
+    `owner/repo`, deduplicates, joins with `, `. Two gates decide whether a
+    URL is shortened at all. Structurally, only URLs on the channel's own
+    GitHub WEB host qualify: `github.com` plus the web host derived from
+    `baseUrl` for GitHub Enterprise — an `api.`-prefixed baseUrl host
+    contributes only its stripped form, never the raw API host, and paths
+    under the baseUrl's own API prefix (e.g. `/api/v3/`) are excluded, so a
+    pasted REST URL cannot shorten to `repos/octo` or `api/v3`. Any other
+    host — `gist.github.com`, `gitlab.com`, an arbitrary site — passes
+    through unchanged for validation to reject, which closes the "first two
+    segments of any host" class. On a qualified
+    host, a URL whose first path segment is a reserved GitHub area (`orgs`,
+    `apps`, `settings`, `trending`, ...) still passes through unchanged so
+    validation rejects it instead of silently filtering a nonexistent
+    repository. That area list is best-effort by construction — a denylist
+    of GitHub's top-level paths cannot be complete, and a future area can
+    reintroduce the hazard until it is added. A snapshot assertion pins the
+    whole exported set (removing any member fails it), an enumerated test
+    keeps every listed root rejected, and explicit regression pins cover the
+    reported shapes including a capitalized root. Other non-URL entries
+    pass through unchanged so validation can name them.
+  - Validation (github only): when `repoFilterMode` is active, an empty list
+    is `repoFilterRequired`; entries that still fail the repository regex
+    after normalization are `invalidRepoId`. When the mode is `off`, the list
+    is not validated, matching the runtime's ignore-while-off rule and the
+    conditional-field visibility below.
+  - `buildChannelUpsertRequest` normalizes the github `repoFilter` value with
+    the same function before sending.
+  - `initialFieldValue` seeds `repoFilterMode` with `off` for existing
+    instances whose config lacks the key (the generic existing-instance path
+    would otherwise leave the select empty).
+- `ChannelEditorDialog.tsx`: the list field is rendered only while the mode
+  is active (progressive disclosure). Visibility and validation are gated on
+  the same predicate, so a hidden field can never strand a save. The draft
+  keeps the list text while the mode is `off`, so re-enabling restores it.
+- i18n (en + zh): field labels ("Repository Filter" / "Filtered repositories"),
+  mode option labels (Off / Allowlist — only listed repositories / Blocklist —
+  all except listed), descriptions (including the URL-paste note and the
+  bound-PR-watch boundary), placeholder `owner/repo, owner/repo`, and the two
+  validation messages.
+
+### Parity
+
+`channel-editor-parity.test.ts` gains a repo-filter table: the same configs
+feed the editor mirror and `plugin.management.validateConfig`, using the
+plugin's own descriptor (active mode + empty list, malformed entry, valid
+allowlist/blocklist, off + stale list).
+
+## Design decisions and rationale
+
+- **Separate intake filter, not a new `groupPolicy` value.** `GroupPolicy` is
+  shared by every channel and enforced by `GroupGate`; adding `blocklist`
+  there would change access-control semantics across all platforms. An
+  adapter-level filter is GitHub-only, sits where `reasonFilter` already sits,
+  and composes with any group policy.
+- **Explicit `off` mode instead of "empty list means off".** An empty
+  allowlist must not silently mean "block everything" or "filter disabled";
+  the mode makes the intent explicit and lets the runtime reject the
+  ambiguous combination.
+- **Ignore the list while off.** Operators can park a list, switch the filter
+  off, and save unrelated edits without the parked list blocking the save —
+  the same tolerance the store already grants unchanged numeric values.
+- **Normalize URLs in the editor, keep the runtime strict.** Pasting a
+  repository or PR URL is the natural gesture; the editor shortens it on
+  save. `settings.json` hand-edits keep one canonical spelling and get a
+  clear error otherwise.
+- **Notifications filtered, watch events not.** Every notification is
+  filtered, including notifications about bound PRs — they arrive through the
+  same intake. Bound-PR watch is an explicit user subscription with its own
+  durable state machine; filtering it is a separate decision and stays out
+  of this change.
+
+## Files affected

+- `packages/channels/github/src/GithubAdapter.ts`, `index.ts`,
+  `GithubAdapter.test.ts`
+- `packages/web-shell/client/components/channels/channel-editor-state.ts`,

+  filter editor captures)
+- `docs/users/features/channels/github.md`
+- `docs/design/github-repo-filter.md`, `docs/design/github-repo-filter.zh-CN.md`
+
+## Validation plan
+
+- Unit: adapter normalize/validate rules; poll-loop skip behavior for both
+  modes (case-insensitive match, journal cap and collapsed row, cursor
+  advances); editor normalization/validation/save payload; parity table.
+- E2E (`.qwen/e2e-tests/github-repo-filter.md`): save both modes through the
+  daemon API against a local GitHub-compatible stub, observe skipped vs
+  processed notifications and the `repo_filter` journal rows; editor
+  rendering checks.
+
+## Acceptance criteria
+
+- `repoFilterMode: allowlist` processes only listed repositories; `blocklist`
+  processes all except listed; `off`/absent processes everything.
+- An active mode with an empty or malformed list is rejected at save time
+  (daemon and editor) and at connect time (runtime), with matching messages.
+- Filtered notifications are journaled as `repo_filter` skips and do not hold
+  the cursor.
+- The editor shows the repository list only while a mode is active, accepts
+  pasted GitHub URLs, and round-trips stored values unchanged when untouched.
+- Existing channels without the new keys behave exactly as before.

+# GitHub 频道按仓库过滤事件（白名单 / 黑名单）
+
+[English](github-repo-filter.md) | [简体中文](github-repo-filter.zh-CN.md)
+
+状态：已随本次变更实现。
+
+## 问题
+
+GitHub 频道会处理认证账号可见的所有仓库的通知。目前唯一的仓库级控制是
+`groupPolicy: "allowlist"` 加 `groups` 键：想要「除了这些吵闹的仓库以外都处理」
+的管理员无法表达这个意图；想要一个简单事件过滤器的管理员必须先理解访问策略
+机制（群门禁、发言者策略、按仓库覆盖）才能配出来。
+
+在 Web Shell 编辑器里，仓库白名单藏在「Group Policy → Allowlist →
+Allowed repositories」下面。没有黑名单，而且访问策略的框架让「按仓库过滤
+事件」这件简单的事变得不直观。
+
+## 现状
+
+- 入站事件经由 `packages/channels/github/src/GithubAdapter.ts` 的通知轮询循环
+  （`pollOnce`）到达。每条通知的 subject URL 解析出 `chatId = owner/repo`；
+  `reasonFilter` 已经在那里跳过通知、按轮记录有上限的 `reason_filter` 跳过
+  行外加一条折叠计数行，并让游标继续前进。
+- 仓库访问在其后由 `GroupGate`（`groupPolicy` + `groups`）按信封把关。编辑器
+  只为这条访问路径渲染仓库行。
+- 第二个事件源是 PR 状态观察（`runPrStateWatch`），服务于用户在会话里显式
+  绑定到活跃会话的 PR。它不经过通知循环。
+- daemon 存储（`channel-settings-store.ts`）按插件描述符校验每个配置键，并
+  调用插件的同步 `validateConfig` 做跨字段规则。编辑器在
+  `channel-editor-state.ts` 里镜像这些规则；`channel-editor-parity.test.ts`
+  用插件自己的描述符把两侧绑在一起。
+
+## 目标
+
+- 用两种显式模式按仓库过滤入站 GitHub 事件：白名单（只处理列出的仓库）与
+  黑名单（处理列出仓库以外的全部）。
+- 在 Web Shell 编辑器里把过滤器做成一对一等公民、自解释的字段，带仓库格式
+  校验，并容忍粘贴 URL。
+- 通过一个共享校验函数和一张一致性表，让运行时、保存时校验器与编辑器镜像
+  保持同步。
+
+## 范围边界
+
+- 过滤器作用于每一条入站通知，包括绑定到活跃会话的 PR 的通知。只有 PR
+  状态观察事件（`runPrStateWatch`）——用户在会话里显式创建的按 PR 订阅——
+  绕过它。字段描述会写明这一点。
+- `groupPolicy` / `groups` 的访问控制含义不变。仓库过滤器是额外的入站过滤；
+  两者同时生效时，有效集合是它们的交集。
+- 不改其他频道、不改 `GroupGate`、不改共享的 `GroupPolicy` 类型。
+
+## 方案
+
+### 配置（GitHub 插件）
+
+两个新的扁平描述符字段，放在 `reasonFilter` 之后：
+
+- `repoFilterMode`：枚举 `off | allowlist | blocklist`，默认 `off`。
+- `repoFilter`：`owner/repo` 条目的字符串列表。
+
+```json
+{
+  "type": "github",
+  "useLocalGh": true,
+  "groupPolicy": "open",
+  "repoFilterMode": "blocklist",
+  "repoFilter": ["octo/noisy-repo", "octo/archive"]
+}
+```
+
+用扁平字段（而不是一个 object 字段），因为 Web Shell 编辑器无法编辑
+`object` 类字段。
+
+### 运行时（`GithubAdapter.ts`）
+
+- `validateRepoFilterConfig(config)` —— 导出的纯函数，返回字符串错误或
+  `undefined`。规则：
+  - `repoFilterMode` 缺省或 `off`：完全忽略列表（过滤器关闭时，陈旧列表
+    永远不会挡住保存或连接）。
+  - `repoFilterMode` 为 `allowlist`/`blocklist`：`repoFilter` 必须是非空
+    字符串数组，每项 trim + 小写后匹配
+    `^[A-Za-z0-9_.-]+/[A-Za-z0-9_.-]+$`。生效的白名单若列表为空会静默丢掉
+    所有事件，因此直接拒绝。
+  - 其他 mode 取值一律拒绝。
+- `normalizeRepoFilter(config, name)` 调用同一个校验器，出错即抛；
+  `connect()` 在 `reasonFilter` 旁边存入 `{ mode, repos: Set<string> } | null`。
+- 在轮询循环里，紧跟 `extractFromSubjectUrl` 之后、`reasonFilter` 之前：
+  白名单跳过不在集合里的仓库，黑名单跳过在集合里的仓库（大小写不敏感）。
+  被跳过的通知写 stderr、发 `repoFilter.skip` 调试载荷，并按
+  `inbound / skipped / repo_filter` 记入日志，沿用与 `reason_filter` 相同的
+  每轮上限（20 行）与折叠计数行。游标越过被过滤的通知继续前进，与
+  reason 过滤完全一致。
+- `index.ts` 的 `validateConfig` 调用 `validateRepoFilterConfig`，因此
+  daemon 在保存时就以运行时相同的消息拒绝非法组合。
+
+### 编辑器（`web-shell`）
+
+- `channel-editor-state.ts`：
+  - `normalizeRepositoryFilterInput(value, baseUrl)` —— 按逗号拆分、trim、
+    剥掉粘贴可能带上的句尾标点、小写，把 GitHub web URL
+    （`https://github.com/owner/repo`，可带 `.git`、尾斜杠、query、fragment
+    或 `/pull/123` 式后缀）缩短为 `owner/repo`，去重后用 `, ` 连接。是否
+    缩短由两道门决定。结构上，只有频道自己的 GitHub WEB 主机上的 URL 才
+    可缩短：`github.com` 加上由 `baseUrl` 派生的 GitHub Enterprise web
+    主机——带 `api.` 前缀的 baseUrl 主机只贡献去前缀后的形式，绝不加入
+    原始 API 主机；baseUrl 自身 API 前缀（如 `/api/v3/`）下的路径也被
+    排除，因此粘贴 REST URL 不会被缩短成 `repos/octo` 或 `api/v3`。其他
+    任何主机——`gist.github.com`、`gitlab.com`、任意站点——原样透传交给
+    校验拒绝，从结构上关闭「任意主机的头两段路径」这一类隐患。在合格
+    主机上，首段路径是 GitHub 保留区域（`orgs`、`apps`、`settings`、
+    `trending` 等）的 URL 仍原样透传，让校验拒绝它，而不是静默地去过滤
+    一个不存在的仓库。这份区域清单在构造上就是尽力而为——对 GitHub 顶层
+    路径做黑名单不可能穷尽，未来新增的区域在被补进清单之前会重新引入该
+    隐患。快照断言钉住整个导出集合（移除任何成员都会红），枚举测试保证
+    每个已列根路径都被拒绝，显式回归钉覆盖报告所列形态（含大写根路径）。
+    其他非 URL 条目也原样通过，让校验能点名它们。
+  - 校验（仅 github）：`repoFilterMode` 生效时，空列表为
+    `repoFilterRequired`；归一化后仍不匹配仓库正则的条目为
+    `invalidRepoId`。mode 为 `off` 时不校验列表，与运行时的「关闭即忽略」
+    规则及下面的条件可见性一致。
+  - `buildChannelUpsertRequest` 在发送前用同一个函数归一化 github 的
+    `repoFilter` 值。
+  - `initialFieldValue` 为配置里缺键的既有实例把 `repoFilterMode` 种子值
+    设为 `off`（通用的既有实例路径否则会让下拉框为空）。
+- `ChannelEditorDialog.tsx`：列表字段只在 mode 生效时渲染（渐进披露）。
+  可见性与校验挂在同一个谓词上，隐藏字段永远不会卡住保存。mode 为 `off`
+  时草稿保留列表文本，重新启用即恢复。
+- i18n（en + zh）：字段标签（「Repository Filter」/「Filtered
+  repositories」）、mode 选项标签（Off / Allowlist — only listed
+  repositories / Blocklist — all except listed）、描述（含粘贴 URL 说明与
+  PR 绑定观察的边界）、占位符 `owner/repo, owner/repo`，以及两条校验消息。
+
+### 一致性
+
+`channel-editor-parity.test.ts` 增加一张 repo-filter 表：同一组配置喂编辑器
+镜像与 `plugin.management.validateConfig`，使用插件自己的描述符（生效
+mode + 空列表、畸形条目、合法白名单/黑名单、off + 陈旧列表）。
+
+## 设计决策与理由
+
+- **独立的入站过滤器，而不是新的 `groupPolicy` 取值。** `GroupPolicy` 由
+  所有频道共享、由 `GroupGate` 执行；在那里加 `blocklist` 会改变所有平台
+  的访问控制语义。适配器级过滤器只属于 GitHub，放在 `reasonFilter` 已经
+  在的位置，并与任何 group policy 复合。
+- **显式 `off` mode，而不是「空列表即关闭」。** 空白名单不能静默地表示
+  「屏蔽一切」或「过滤关闭」；mode 让意图显式，并让运行时拒绝这个歧义
+  组合。
+- **关闭时忽略列表。** 管理员可以停放一份列表、关掉过滤器、保存不相关的
+  编辑，而不被停放的列表挡住保存——与存储对未变更数值已有的容忍一致。
+- **编辑器归一化 URL，运行时保持严格。** 粘贴仓库或 PR URL 是自然手势；
+  编辑器在保存时缩短它。`settings.json` 手编保持唯一规范拼写，否则得到
+  清晰报错。
+- **通知被过滤，观察事件不被过滤。** 每条通知都被过滤，包括绑定 PR 的
+  通知——它们走同一个入站口。PR 绑定观察是带自己持久状态机的显式用户
+  订阅；要不要过滤它是另一个决策，不在本次变更内。

+# Web Shell optional transport capabilities
+
+[English](web-shell-optional-transport-capabilities.md) | [简体中文](web-shell-optional-transport-capabilities.zh-CN.md)
+
+## Problem and scope
+
+An embedded transport can support streaming prompts without exposing the optional daemon recap or native pending-prompt routes. Automatic recap and queue reconciliation must respect advertised capabilities. When `optimisticUserMessage=false`, the authoritative user echo also arrives after the browser starts sending; using the previous user message as the clock anchor briefly shows the previous turn's duration.
+
+This change corrects browser behavior against existing transport contracts. It does not add daemon routes, authentication mechanisms, or persistent client queues.
+
+## Decisions and constraints
+
+- Register automatic recap only when `session_recap` is advertised.
+- Query native pending prompts only when `session_prompt` is advertised. Without it, hold ordinary queued prompts locally while the session is active, then send them sequentially through the normal streaming action and await completion. Recheck ownership, cancellation and host dispatch policy before dispatch. Do not automatically replay an uncertain submission.
+- Keep mid-turn injection independent from native queue support. An explicit host hold still blocks it; missing native queue support alone does not block an advertised mid-turn capability.
+- Do not pair urgent prompt state with a deferred snapshot from an earlier transcript structure. Pure streaming tail appends retain the deferred path.
+- A browser-owned send records its session ID and local start time until the send settles. Both chat layouts use it before an authoritative user echo arrives. Cleanup removes only the same operation's record, so a stale completion cannot clear a newer owner. This state is not sent to the daemon. Remote restored turns retain their authoritative start time.
+
+Local queue entries remain browser-local and are not guaranteed to survive refresh. A transport lacking native queue support cannot expose other clients' pending native prompts. The native-capability path keeps its existing behavior.
+
+## Validation and acceptance
+
+Reproduce missing-capability calls, native queue dispatch on a streaming-only transport, and a clock anchored one hour in the past before changing production code. Verify positive capability controls, sequential completion, failed-send handling, independent mid-turn support, and restored remote timing. Verify local clock cleanup for completion, cancellation, rejection and replacement ownership. Keep UI structure consistency and streaming-throttle coverage.
+
+Component and protocol-fixture tests must distinguish their evidence from a browser end-to-end run. No live account or provider-specific endpoint is required for these regressions. Before merging, run the affected tests, build/bundle, typecheck and formatting/lint checks. Browser validation of a host integration remains separate from those gates.

+# Web Shell 可选传输能力
+
+[English](web-shell-optional-transport-capabilities.md) | [简体中文](web-shell-optional-transport-capabilities.zh-CN.md)
+
+## 问题与范围
+
+嵌入式传输可以支持流式 Prompt，而不提供可选的 daemon 摘要和原生待处理 Prompt 路由。自动摘要和队列同步必须遵守能力声明。使用 `optimisticUserMessage=false` 时，权威用户回显还会晚于浏览器开始发送；以旧用户消息作为计时起点，会短暂显示上一轮的耗时。
+
+本变更修正浏览器对现有传输契约的处理，不新增 daemon 路由、认证机制或持久化客户端队列。
+
+## 决策与约束
+
+- 仅在声明 `session_recap` 时注册自动摘要。
+- 仅在声明 `session_prompt` 时查询原生待处理 Prompt。缺少该能力时，会话活跃期间将普通排队消息保留在本地，随后通过普通流式动作逐条发送并等待完成。发送前重新检查归属、取消和宿主策略。提交结果不明确时不自动重放。
+- 中途注入与原生排队能力独立。显式宿主 hold 仍然阻止注入；仅缺少原生排队能力不能阻止已声明的中途注入能力。
+- 紧急 Prompt 状态不能配对此前转录结构的延迟快照。纯流式尾部追加仍保留延迟路径。
+- 浏览器发起的 send 在结束前记录其会话 ID 和本地开始时间。两种聊天布局在权威用户回显之前使用该起点。清理仅移除同一次操作的记录，避免旧请求完成后清掉新归属的状态。此状态不发给 daemon。远端恢复中的轮次仍保留权威起点。
+
+本地队列条目仍只存在于浏览器，不能保证刷新后保留。缺少原生排队能力的传输不能展示其他客户端的原生待处理消息。具备原生能力的路径保留既有行为。
+
+## 验证与验收
+
+修改生产源码前，复现缺少能力时仍然调用接口、仅流式传输误走原生队列，以及用户回显前计时起点旧了一小时。验证具备能力的对照、逐条完成、发送失败处理、中途注入独立性和远端恢复计时。验证本地计时在完成、取消、拒绝及归属替换后的清理，保留 UI 结构一致性和流式节流覆盖。
+
+组件及协议夹具测试必须与浏览器端到端验证区分。这些回归不依赖真实账号或特定服务商入口。合入前运行受影响测试、构建及 bundle、类型和格式/lint 检查。宿主集成的浏览器验证仍是独立验收。

Do not use `reasonFilter: ["mention"]` as a replacement for `groups.*.requireMention`: GitHub's `mention` reason is sticky at the thread level, so real new @mentions can arrive later under `comment`, `subscribed`, `author`, or other reasons and would be skipped.

+### Repository event filter
+
+Use `repoFilterMode` together with `repoFilter` to filter incoming notifications by repository:
+
+```json
+{
+  "repoFilterMode": "blocklist",
+  "repoFilter": ["octo/noisy-repo", "octo/archive"]
+}
+```
+
+- `"allowlist"` processes only the listed repositories; `"blocklist"` processes every repository except the listed ones; `"off"` (the default) processes everything.
+- Repository names are matched case-insensitively and must be written as `owner/repo`. An active mode with an empty or malformed list is rejected at save time and at channel start.
+- While the mode is `"off"`, a stored list is ignored, so you can park a list without it affecting the channel.
+- The filter composes with `groupPolicy`: when both restrict repositories, only the intersection is processed. It applies to every incoming notification, including notifications about PRs bound to a live session (`deliverToBoundSessions`); only the PR state watch events (`prWatchEvents`) bypass it.
+- Filtered notifications are journaled as `repo_filter` skips in the Channel event timeline and do not hold the poll cursor. Like `reasonFilter` skips, they are marked read with the window and are not replayed when the filter changes.
+
+In the Web Shell editor, **Repository Filter** offers Off / Allowlist / Blocklist, and the **Filtered Repositories** list appears while a mode is active. You can paste repository or PR URLs there; they are shortened to `owner/repo` on save. Only URLs on the channel's own GitHub host are shortened — `github.com`, or the GitHub Enterprise host derived from the API base URL; URLs on any other host are rejected. On that host, URLs under known non-repository GitHub areas (`orgs/`, `apps/`, `settings/`, `trending/`, and similar) are also rejected instead of shortened. That area list is best-effort: a URL from a GitHub area not on the list can still be shortened, so check the saved `owner/repo` entries after pasting.

 Settings → Channels → GitHub exposes the poll interval under **Connection**, in milliseconds. It is kept between 1 and 86400000 (one day): a larger value is clamped to the ceiling and a smaller positive one is raised to 1, because Node rounds a sub-millisecond timeout to about 1 ms and clamps one above its 32-bit range to 1 ms as well — either would turn the poll loop into a hot loop. Leave it empty for the 60000 ms default. When `groupPolicy` is `"allowlist"`, the **Access control** section also shows one row per allowlisted repository, each with a require-mention control and a speaker control.

 Each phase reads the units, their environment files and the installed release again, and refuses unless the previous phase left them as it expects, so an interrupted upgrade resumes at the phase that failed. `--server-unit` and `--harness-unit` name units other than `qwen-managed-agent-server` and `qwen-hosted-harness`; the command finds the installed release, the environment files and the service account through them.
 
-- `check` changes nothing. It verifies the new distribution against its `SHA256SUMS`, compares both releases (version, the Flyway scripts in the server jars, Java, Node.js and Qwen Code), and reads the Harness Broker settings, the unit templates, operator files in the installed `config/` and the release layout. Its `backup-tools` and `runtime-state` rows tell whether `backup` will run with the options given, so pass `check` the backup options too; the plan it prints repeats them. It prints one row per input and a plan with the manual steps where they fall, and exits 1 on any FAIL. The `database` row fails when the new release changed or removed a script the installed database ran: until the first formal release, a release may rewrite its schema baseline in place, and such a release cannot start on the existing database. It also fails when the release adds a versioned script that does not sort after the newest one the installed database ran, which Flyway refuses to apply.

It prints one row per input and a plan with the manual steps where they fall, and exits 1 on any FAIL. The `database` row fails when the new release changed or removed a script the installed database ran: until the first formal release, a release may rewrite its schema baseline in place, and such a release cannot start on the existing database. It also fails when the release adds a versioned script that does not sort after the newest one the installed database ran, which Flyway refuses to apply.
 - `stop` repeats the checks above `backup-tools` and stops nothing unless they pass. The `backup-tools` and `runtime-state` rows gate only `backup`, so settle them with `check` before `stop`. It stops the control plane, stops the Runtime workers that `KillMode=process` leaves in its cgroup and waits for them (`--timeout`, 60 seconds by default), then stops the Harness. It counts the workers in the cgroup systemd names, in the unified hierarchy or on cgroup v1 in systemd's own, and refuses when it cannot read that cgroup. Once the new release is installed, `stop` skips the checks, so it also stops a control plane that `start` left running. The JVM exits 143 on `SIGTERM`, so a control-plane unit installed without the template's `SuccessExitStatus=143` shows as `failed` after the stop; `stop` says so, and once the template's change is carried over, `systemctl reset-failed` clears the state.
 - `backup --to <new empty directory>` needs both units stopped and no worker left, and refuses once the new release is installed, because its `from.release` would then name the new release. A directory that already exists must be empty and belong to root. It writes `database.sql` with `mysqldump`, passing the unit's `SPRING_DATASOURCE_*` credentials through an option file in a temporary directory outside the backup rather than on the command line; `mysqldump` reads no other option file, so root's `~/.my.cnf` cannot replace them. It writes `runtime-state.tar` of the Runtime state directory, `configuration.tar` of the unit files, their environment files, the Harness credentials file and the `SPRING_CONFIG_ADDITIONAL_LOCATION` files, and `release-config.tar` of the installed `config/` and any of those files that live in the release, recorded by their path in the release. A file that is a symbolic link goes in as the link and as the file it names. Every file is `0600` in a `0700` directory, and `backup.json`, written last, records their checksums, the database the dump is of, and where `install` leaves the previous release. `--mysqldump <path>` names another client, and `--skip-database` skips the dump when the database is backed up another way. A backup that fails, or that `SIGINT`, `SIGTERM` or `SIGHUP` ends, removes what it wrote and the option file. A `SIGKILL` removes nothing; remove the `${TMPDIR:-/tmp}/qwen-managed-agent-upgrade-*` directory it leaves, which holds the credentials.
   - `check` and `backup` take the Runtime state directory from the server's own configuration. They run the new release's server jar as the control-plane unit runs the server: with its account, working directory and environment, and the launcher's default `config/application.yml` when `SPRING_CONFIG_ADDITIONAL_LOCATION` is unset or empty. The jar prepares Spring's environment the way the server does, so every configuration file, import and profile counts, as do `SPRING_APPLICATION_JSON`, system properties from `JAVA_TOOL_OPTIONS` and relaxed names, and a relative directory is resolved in the unit's working directory. It starts nothing and opens no connection. When it cannot resolve the configuration, or the unit passes the launcher arguments, which `systemctl` does not print exactly, `backup` refuses until `--runtime-state <directory>` names the directory the server uses, or `--runtime-state none` says it keeps none. Without a configured directory, as on a deployment without the tool path, `backup` archives no Runtime state and says so.
 - `install --backup <directory>` refuses a backup of another release, a backup file that changed, a backup the control plane has started since, and a backup of another database than the unit's `SPRING_DATASOURCE_URL` names. It copies the release to `<distribution>-releases/<version>`, such as `/opt/qwen-managed-agent-releases/<version>` (`--releases` names another directory; pass the same one to every phase), copies operator files from the installed `config/` with their owner and mode, and points the distribution path at the new release with one rename. The copy's own files, those `SHA256SUMS` lists, are made readable by every account, so the service account can run a release extracted with a restrictive umask. The first run moves the installed directory to `<releases>/<old version>` and puts a link in its place, so the units keep their paths. The previous release stays where it is. An existing `<releases>/<version>`, such as the archive extracted there, is used only when its `SHA256SUMS` is the new distribution's and its files match it, and its listed files are made readable the same way; a copy that fails is removed. A crash between the first run's two renames leaves `<distribution>.upgrade-<suffix>` beside the missing distribution path; every phase then names the `mv -T` that finishes the install. An install killed at another step can leave a partial copy `.<version>.partial-<suffix>` in the releases directory, an `<distribution>.upgrade-<suffix>` link beside the distribution path, or an operator file's `.tmp-<suffix>` copy in the new release's `config/`; the `layout` row lists them, and the next `install` removes them. The suffix is the eight hexadecimal digits `install` generates, so an operator's own `<distribution>.upgrade-backup` is left alone. Run again once the release is installed, as after an interrupted session, `install` says so and points at `start`.
 - `start` refuses before `install`, and while the Harness Broker settings still need step 5 below. It starts the Harness, or restarts one that an earlier `start` left running so that it reads what was fixed since, runs `bin/qwen-managed-agent-server --check` as the service account with the unit's environment, starts the control plane only when that passes, and waits for a healthy actuator (`--timeout`, 300 seconds by default; one probe waits at most 5 seconds). Flyway migrates the schema during this start. A control plane that exits before it is healthy is stopped and reported, even one that systemd's `Restart=on-failure` would bring up when it runs it again: an exit during the start that migrates the schema is worth reading in the journal before `start` runs again. One that is still not healthy at the timeout keeps running; read its journal, then run `verify`, or `stop` and `start` again.
-  - `start` and `verify` find the Harness, the control plane and its health endpoint the same way, so a port or address set where `server.env` does not show it counts: in a configuration file, on the command line or in `SPRING_APPLICATION_JSON`. The Harness is where `qwen.managed-agent.harness.base-url` says. The control plane is where `server.port`, `server.address` and `server.ssl` bind it, with a wildcard address reached on the loopback interface, and the health endpoint follows Spring Boot's management settings: a `management.server.port` of its own moves it to that port, on `management.server.address` and under `management.server.base-path`. `--server-url <url>` names the control plane instead, for example behind a proxy, and the health endpoint is then `<url>/actuator/health`. A phase checks only the URLs it dials: both probe the health endpoint, and `verify --tenant` also reads the API when the auth mode is `open`. A port of 0 or below gives no URL to wait on, so the phase refuses until `--server-url` names one; it also refuses a URL `fetch` refuses to dial: a link-local IPv6 address with its zone, a port the Fetch standard blocks (6000, for one), or a `--server-url` without `http://` or `https://`, with a user name or password, which the refusal prints as `***`, or with a query or a fragment, which the paths appended to it would land in; `start` likewise refuses a Harness URL that is not `http` or `https`, and, while the Harness is enabled, one the server's Harness connector would refuse: anything but an `http` or `https` URL with a host and without credentials, a query or a fragment, as the server reads it with `java.net.URI`, so a host name with an underscore is refused too; when the configuration does not resolve, `start` itself refuses credentials, a query or a fragment and leaves the rest to the preflight. When the health endpoint does not report UP, `start` and `verify` say what it answered last; for a certificate this host does not trust, point `NODE_EXTRA_CA_CERTS` at its CA when you run the command. When the configuration does not resolve, or the unit passes the launcher arguments, they use the URLs `server.env` names and print a line that says so.

When the health endpoint does not report UP, `start` and `verify` say what it answered last; for a certificate this host does not trust, point `NODE_EXTRA_CA_CERTS` at its CA when you run the command. When the configuration does not resolve, or the unit passes the launcher arguments, they use the URLs `server.env` names and print a line that says so.
 - `verify` runs `--check --online` the same way and reads the actuator, waiting up to `--timeout` (300 seconds by default) for its answer. With `--tenant <id>`, it reads the tenant's most recent Session and its Items, before `--turn` creates one; `--turn` creates a Session and waits for one Turn, which calls the model, polling past a `5xx` answer or a dropped connection; when the Session read is skipped, the `turn` row says so. No request outlasts `--timeout`. A request without an actor lists only Sessions outside Workspaces; `--actor <id>` sends one through the header `QWEN_MANAGED_AGENT_TRUSTED_ACTOR_HEADER` names. `verify` reads the auth mode the way `backup` reads the Runtime state directory, and signed authentication skips both reads; read a Session through the ingress instead.
 
 The command starts and stops units only. It never stops ingress, installs Qwen Code, edits environment or unit files, or deletes a release. When `check` warns that a unit template changed, carry the change over to the installed unit and run `systemctl daemon-reload` before `start`.

 - `stop` 重新执行 `backup-tools` 之前的各项检查，检查不通过就什么都不停。`backup-tools` 和 `runtime-state` 两行只约束 `backup`，因此请在 `stop` 之前先用 `check` 让它们通过。它先停止控制面，再停止 `KillMode=process` 留在其 cgroup 中的 Runtime worker 并等待它们退出（`--timeout`，默认 60 秒），最后停止 Harness。它在 systemd 给出的 cgroup 中清点 worker：unified 层级下直接读取，cgroup v1 下读取 systemd 自己的层级；读不到该 cgroup 时拒绝执行。新版本安装之后，`stop` 不再执行这些检查，因此也能停止 `start` 留下仍在运行的控制面。JVM 收到 `SIGTERM` 后以 143 退出，因此没有模板中 `SuccessExitStatus=143` 的已安装控制面 unit 在停止后会显示为 `failed`；`stop` 会说明这一点，把模板的改动同步过去之后，`systemctl reset-failed` 可以清除该状态。
 - `backup --to <新的空目录>` 要求两个 unit 都已停止且没有遗留 worker；新版本安装之后它会拒绝执行，因为这时备份的 `from.release` 会指向新版本。已存在的目录必须为空且属于 root。它用 `mysqldump` 写出 `database.sql`，unit 中的 `SPRING_DATASOURCE_*` 凭据通过备份目录之外某个临时目录里的选项文件传入，而不是放在命令行上；`mysqldump` 不读其他选项文件，root 的 `~/.my.cnf` 因此无法替换这些凭据。它写出 Runtime 状态目录的 `runtime-state.tar`；`configuration.tar`，其中包含 unit 文件、它们的环境文件、Harness 凭据文件和 `SPRING_CONFIG_ADDITIONAL_LOCATION` 指向的文件；以及 `release-config.tar`，其中包含已安装版本的 `config/` 和上述文件中位于版本目录内的部分，按它们在版本目录中的路径记录。符号链接形式的文件既以链接本身归档，也归档它指向的文件。所有文件都是 `0600`，所在目录为 `0700`；最后写入的 `backup.json` 记录各文件的校验和、导出的是哪个数据库，以及 `install` 会把旧版本放在哪里。`--mysqldump <path>` 指定其他客户端；数据库已用其他方式备份时，用 `--skip-database` 跳过导出。备份失败，或被 `SIGINT`、`SIGTERM`、`SIGHUP` 中止时，会删除已写出的内容和选项文件。`SIGKILL` 不会删除任何东西；它留下的 `${TMPDIR:-/tmp}/qwen-managed-agent-upgrade-*` 目录里有凭据，请删除该目录。
   - `check` 和 `backup` 从服务端自己的配置中取得 Runtime 状态目录。它们按控制面 unit 运行服务端的方式运行新版本的服务端 jar：使用该 unit 的账号、工作目录和环境；`SPRING_CONFIG_ADDITIONAL_LOCATION` 未设置或为空时，与 launcher 一样默认使用 `config/application.yml`。该 jar 按服务端的方式准备 Spring 环境，因此所有配置文件、import 和 profile 都会生效，`SPRING_APPLICATION_JSON`、`JAVA_TOOL_OPTIONS` 中的系统属性和 relaxed binding 形式的名称也一样；相对路径的目录按 unit 的工作目录解析。它不启动任何组件，也不建立任何连接。如果无法解析配置，或者 unit 给 launcher 传了参数（`systemctl` 打印的参数无法准确还原），`backup` 会拒绝执行，直到用 `--runtime-state <目录>` 指明服务端实际使用的目录，或用 `--runtime-state none` 说明不保存 Runtime 状态。没有配置状态目录时（例如未开启工具路径的部署），`backup` 不归档 Runtime 状态，并明确说明。
 - `install --backup <目录>` 拒绝其他版本的备份、内容有变化的备份文件、控制面在备份之后又启动过的备份，以及所导出的数据库与 unit 的 `SPRING_DATASOURCE_URL` 不同的备份。它把新版本复制到 `<分发路径>-releases/<version>`，例如 `/opt/qwen-managed-agent-releases/<version>`（用 `--releases` 指定其他目录，并在每个阶段都传同一个），把已安装版本 `config/` 中的运维文件连同属主和权限复制过去，再用一次 rename 把分发路径指向新版本。副本中属于版本自身的文件（即 `SHA256SUMS` 列出的文件）会设为所有账号可读，所以即使解压时用了严格的 umask，服务账号也能运行该版本。第一次运行会把已安装的目录移到 `<releases>/<旧版本>`，并在原位置放一个链接，因此 unit 中的路径不变。旧版本保留在原处。已存在的 `<releases>/<version>`（例如直接解压到那里的发行包）只有在其 `SHA256SUMS` 与新分发产物相同、且文件与之相符时才会被使用，其中列出的文件同样会设为所有账号可读；复制失败时会删除复制出的内容。如果第一次运行在两次 rename 之间崩溃，分发路径会缺失，旁边留下 `<分发路径>.upgrade-<后缀>`；此后每个阶段都会给出完成安装所需的 `mv -T` 命令。在其他步骤被杀掉的 install，可能在版本目录里留下部分副本 `.<version>.partial-<后缀>`，在分发路径旁留下 `<分发路径>.upgrade-<后缀>` 链接，或在新版本的 `config/` 里留下运维文件的 `.tmp-<后缀>` 副本；`layout` 行会列出它们，下一次 `install` 会删除它们。后缀是 `install` 生成的 8 位十六进制数，因此运维自己的 `<分发路径>.upgrade-backup` 之类不会被删除。版本安装完成后再次运行（例如会话中断后），`install` 会说明已经安装并提示运行 `start`。
 - `install` 之前，以及 Harness 的 Broker 配置仍需按下文第 5 步修改时，`start` 会拒绝执行。它先启动 Harness（如果之前某次 `start` 留下了正在运行的 Harness，则重启它，以读入此后修改过的内容），再以服务账号、按 unit 的环境运行 `bin/qwen-managed-agent-server --check`，通过后才启动控制面，并等待 actuator 报告健康（`--timeout`，默认 300 秒；单次探测最多等待 5 秒）。Flyway 在这次启动中迁移 schema。控制面在健康之前退出时会被停止并报告，即使 systemd 的 `Restart=on-failure` 再次运行它就能起来也是如此：迁移 schema 的这次启动中出现了退出，应先查看日志，再重新运行 `start`；超时仍未健康时控制面保持运行，请查看其日志，然后运行 `verify`，或先 `stop` 再重新 `start`。
