fix(config): show the telemetry setting default as on, matching the runtime

The settings schema declared telemetry default false while the resolver (telemetry_consent_from_env) treats an unset value as on, so the settings API reported default false for a default-on policy. Landed in Engine push 18 (CW-7875) with the CHANGELOG line the review wrote (CW-7987 REVIEW.md finding 2; the packet's line was not used). This is the committed part only: CW-7987 stays open for the active-version readback and the ingest bundle rebuilt from the frozen candidate. Review: farm runs 20261112T110021Z-gtelrev-config-37102e (codewhale-config, 21 run, 21 passed, 823 skipped) and 20261112T110024Z-gtelrev-telem-751b20 (codewhale-telemetry, 53 run, 53 passed).

 - **Token gate**: All runtime API calls carry `CODEWHALE_RUNTIME_TOKEN`
 - **Chat allowlist**: Only chats/users listed in `WECOM_CHAT_ALLOWLIST` can interact. First-pairing mode (`WECOM_ALLOW_UNLISTED=true`) is meant for onboarding only
 - **Approval required**: Tool calls from WeCom sessions must be approved — either via explicit `/allow <id>` commands or natural-language keywords (`允许`, `yes`, `ok`, etc.)

 ## [Unreleased]

- **Removed (crate API):** the unwired `codewhale-hooks` dispatcher and its stdout, JSONL and Unix-socket sinks; `codewhale-core`'s `session`, `journal` and `ids` modules and the `hooks` argument of `Runtime::new`; `codewhale-runtime::resource_telemetry`; ten unreferenced public functions; and the duplicate `codewhale-agent` crate. `hook_sinks.unix_socket_path` still parses and is ignored. CLI, TUI and app-server behavior is unchanged.
- **First-run setup:** installer downloads retry up to three times and remove partial files after a failed attempt. Folder trust uses 1 to trust, 2 to continue untrusted, and 3 or Esc to quit; letters do nothing. Provider pickers consistently say "needs key", and the unconfigured custom placeholder says "needs endpoint" while configured-route errors remain visible.
- **Quota-window reset text:** a rate-limited turn now gives the reset time in plain words such as "19h29m" instead of Rust debug output like `Some(70168s)`, and leaves the reset clause out when the provider gives no reset time. An OpenCode Go message points at that provider's own key with `codewhale auth set --provider opencode-go`, without repeating a hint the message already carries. (CW-8209)
- **Usage-reporting collector:** accepts runtime schema 6 alongside existing versions and keeps schema 6 reports first-party only.
-
- **Source-build toolchain:** Rust 1.100.0 is pinned consistently across local source builds, CI, Docker, Dev Containers and CNB recipes. The minimum supported Rust version remains 1.89.
- **Terminal input recovery:** retains a wake event from a replaced reader, suppresses retired events observed during a child-terminal handoff, and closes only the handoff window owned by that scope.
-
- **Plugin index hooks:** hooks with the same name and event now have distinct row IDs, so clients can keep every configured hook visible.
- **Extension service approvals:** plugin service acts use the session permission gate and retain their approved or refused act records when a tool call fails. Closing a call seals its broker-act record so a late approval cannot authorize an unrecorded act. Ordinary nested-call receipts may still show an in-flight outcome when cancellation ends the call early.
- **Delayed-message workspaces and shell stdin approvals:** `send_later` `schedule` now keeps its workspace inside the session's reachable paths instead of accepting an arbitrary directory, and `send_later` approval prompts show the requested workspace; session shell grants now match exact inputs when `stdin` (`stdin`, `input`, `data`) is supplied instead of reusing a command-only grant across different `stdin`.
-
- **Installers no longer say Computer Use comes bundled:** the macOS install script and the install guide no longer print or state that Computer Use ships with the binary or needs Node.js 20. Computer Use is released separately and stays off until you turn it on.
- **Charts in the transcript:** the model can now show numbers as a small chart with the new read-only `show_data` tool: a one-row sparkline, up to 24 labelled bars, or a multi-row trend. The TUI paints it in the transcript with the terminal kit, including after a session is restored, and every value is also in words, so the model and other clients get the same facts as text. Input the chart cannot show honestly (a non-finite number, more than 1024 points or 24 bars, a label over 120 characters) is refused with the limit it broke.

Input the chart cannot show honestly (a non-finite number, more than 1024 points or 24 bars, a label over 120 characters) is refused with the limit it broke.
- **Terminal widgets:** narrow action hints wrap, scrollbars reach the final row, progress bars show fractional cells, focused tabs and panels are clearer, and the shared terminal kit supports measured ocean themes and reduced-motion-aware water drift.
-
 - **Renaming sessions with Chinese titles:** the session picker no longer rejects a Chinese, Japanese, Korean or emoji title of more than about 33 characters as "Title must be 1–100 characters". It now counts characters, as the message says and as `/rename` and the Runtime API already did, so any title up to 100 characters is accepted. Thanks [@luochen211](https://github.com/luochen211) (PR 7322).
 - **Non-ASCII file names:** `/diff`, the `@git` and `@diff` mentions and the Runtime API workspace diff now show paths with Chinese, emoji and other non-ASCII characters as written instead of as quoted octal escapes, and the turn context no longer lists the workspace root as an empty "Active paths" entry. Thanks [@luochen211](https://github.com/luochen211) (PR 7317).
 - **Session names after a crash, and keep-forever snapshot retention:** a session name saved right after a crash that cut off the previous session-index line is no longer lost, because the new entry now starts on its own line; and a very large `[snapshots] max_age_days` (such as `9223372036854775807` for "keep forever") no longer wraps around and deletes every undo snapshot at session start. Thanks [@luochen211](https://github.com/luochen211) (PR 7316).
 - **Blank environment variables:** exporting a variable empty (for example `CODEWHALE_MODEL=` from a compose `${VAR:-}` template) no longer hides its legacy alias. `DEEPSEEK_MODEL`, `DEEPSEEK_BASE_URL`, `KIMI_BASE_URL`, `DEEPSEEK_FORCE_HTTP1`, `DEEPSEEK_STREAM_OPEN_TIMEOUT_SECS` and the other provider alias variables now apply as they do when the primary is unset. Thanks [@luochen211](https://github.com/luochen211) (PR 7315).
- **MCP and language servers that send requests mid-call:** a tool call no longer fails with "neither a result nor an error" when an MCP server sends a `ping` or other request that reuses the call's id while the call is running, and a language server's `workspace/configuration` or similar request no longer ends a pending LSP request. Codewhale now answers `ping`, answers other server requests with "Method not found" (it never advertised them), keeps waiting for the real reply, and a refused answer over Streamable HTTP no longer drops the connection to legacy SSE. Thanks [@luochen211](https://github.com/luochen211) (PR 7319).
- **Qwen Code as an external agent:** Codewhale now finds an installed Qwen Code CLI (`qwen`, 0.6.1 or newer) and can run it as a session over ACP with `qwen --acp`. `GET /v1/agents/external` lists it, an older install is reported as needing `npm i -g @qwen-code/qwen-code@latest`, and sign-in stays inside Qwen Code (`/auth`). Thanks [@MannXo](https://github.com/MannXo) (#7293).

Thanks [@MannXo](https://github.com/MannXo) (PR 7293).
 - **Telemetry setting default:** the settings schema API reports telemetry's default as on, matching what Codewhale does when you have not chosen.
 - **Auto routing abstention:** when the decision model marks a tier, effort or shadow answer `abstained: true`, Auto no longer acts on it, even with `min_confidence = 0`: an abstained tier takes the local fallback, an abstained effort keeps the tier and drops only the effort, and the routing receipt lists the abstained questions.
 - **Plugin index (Runtime API):** a new `GET /v1/apps/plugin-index` route lists plugins, skills, connectors, hooks and hand-written commands with kind, source and state, and `/v1/commands` rows say which plugin (`plugin_id`) added a command and whether a command came from the project (`workspace_sourced`) (CW-8092).
 - **Model commands and routing:** `codewhale model list` now lists every custom endpoint you have configured, under its own name. `codewhale model resolve` no longer refuses a model on a custom endpoint, router or local server whose model list has not been fetched yet; once a list is fetched, a model missing from it is still refused. Automatic routing marks a context window as verified only when the route itself supplies it, and no longer reports a guessed output limit.
 - **ACP:** when a plugin tool asks the core to run a tool that needs approval, the editor now gets a `session/request_permission` on the plugin tool's call that names the nested tool and its input; before, the prompt ended with an internal error (CW-8050).
- **Website maintainer and cron secrets:** the manual cron trigger is rate limited, admin sign-in and the cron secret require a 32 to 512 character secret with at least 8 distinct characters that is not a repeated pattern, and changing the maintainer token signs out existing admin sessions.
- **Chat bridges thread ownership:** Chat bridges now list and resume only the threads the chat itself created: `/threads` shows owned threads, `/resume` refuses any other thread id with one fixed message, and `/new` always starts a new thread. In an existing thread map each chat keeps only the thread it is bound to, so threads it created earlier and left are no longer listed or resumable; a thread that several chats already pointed at is usable from none of them (send `/new`). Review `thread-map.json` after upgrading.
- **Skill and plugin installs:** skill and plugin installs now enforce the uncompressed size cap on the whole decompressed archive, and reject archive entries with names longer than 4096 bytes.
-
 - **README and contributor credit:** the repository front page now opens the way the website does: the line "The model can be anyone's. The agent should be yours.", one sentence on what Codewhale is, the install command and one picture, with reference detail moved into the linked guides; the 18 translated READMEs follow the same structure and say they are machine-drafted. The contributor wall and the website now count the same 433 people (407 GitHub accounts and the commit authors whose email is not linked to an account), where the website had counted accounts only. `DEPENDENCY_SECURITY.md` moved into `docs/dependency-maintenance.md`, and `.github/SUPPORT.md` says where to ask for help.
 - **Website Plugins page:** The website's Plugins page now describes what the released version does, and a labelled section says what 0.10.3 adds: one Plugins place, Standard and Creator mode, and the Permissions control.
- **Website `/app` captures:** the `/app` page's desktop build screenshots (`conversation.webp`, `approval.webp`, `model-picker.webp`) and their alt and caption text have been refreshed from the current 0.10.3 desktop UI.
- **First-time guide on the website:** a new docs page, "Use Codewhale for the first time" (`/docs/first-time`, English and Simplified Chinese), walks someone who has never used a terminal through opening one, installing, choosing the folder Codewhale works in and when that choice matters, opening a terminal in a folder from Finder or File Explorer, connecting a model, a first task, and stopping, undoing and quitting. The install page gains a short "New to the terminal?" block for macOS and Windows that links to it, and `llms.txt` carries the same steps.
 - **Plugin docs and plugin-creator:** Docs now say everything you add is a plugin. The bundled plugin-creator skill no longer tells an agent never to trust or enable a plugin (in Full Access it may, for one it wrote and installed from its project), points code and screen plugins at cordis-plugin-development, and an untouched copy from 0.10.2 now upgrades. The Chinese extension and Runtime API docs now say editor ACP sessions get plugin tools and configured MCP servers.
 - **Model thinking:** New installs show model thinking by default: it streams live in the transcript and collapses under a "Thought for …" header when the answer starts. Existing installs keep their saved setting; turn it on under Model reasoning in chat in /config.
 - **Footer clock:** The footer clock and phase now say "thinking", matching the transcript.

 ### Fixed

- Child processes now inherit only the standard locale variables (`LC_ALL`, `LC_CTYPE` and the other locale categories, plus `LC_TERMINAL` and `LC_TERMINAL_VERSION`) and a listed set of `DOTNET_` host, SDK and runtime settings. Other `DOTNET_` variables, including application configuration keys, are no longer passed to child processes or MCP servers.
 - **Starting after a hard kill:** the Engine now starts when its process was killed and its data directory was then deleted. A socket owner record whose process is dead and whose data directory, the one this start selected, no longer exists is discarded instead of failing every start with "Failed to resolve ... tasks/runtime". A home reached through a symbolic link, such as one under macOS /tmp, is not covered yet.
 - The install guide's note for a first message that gets no answer now describes v0.10.2: connect a model with `/provider`, and restart if messages stay saved for later after you connect. It described v0.10.0's key screen. The Chinese guide carries the same correction.
 - Project activity on the site now comes from a server-side snapshot with a freshness record, the browser no longer calls GitHub, and count sentences use the right plural form in every language.

 - **Windows uninstall removes the receipt and update leftovers.** The installer's uninstaller also deletes `.codewhale-install.sha256` and `codewhale.old-*`/`codew.old-*` left by a self-update, so `bin` can be removed. Refs #7091.
 - **Windows `/undo` matches recorded file paths regardless of case.** A write recorded under a different drive-letter or directory case, or a `\\?\` prefix, is no longer dropped from the restore plan. Refs #6970.
 - **Windows: Fleet and metrics read live files again.** Replaying a Fleet ledger and reading audit or receipt records no longer fail with a sharing violation while their writer is still open; the same regular-file, link and identity checks apply. Plugin enablement now says which snapshot check refused (stage root, content identity or final check) instead of one generic message. Generated protocol and SDK exports keep LF line endings in Windows checkouts.
- **Sessions in one folder no longer leave each other's sub-agents read-only or private:** a second session works beside another one, stale or suspended included, the older sub-agent store upgrades right away, and a store that cannot be opened is retried on the next sub-agent change instead of needing a restart. While another Codewhale session, a suspended one included, is open in a folder the desktop app or `serve` was asked to work in (other than the folder it started in), that Runtime still refuses sub-agents that would edit the folder directly; isolated worktrees are unaffected. A sub-agent store that cannot be opened shows its refusal once instead of repeating cleanup warnings on every sidebar refresh. Restart any session started with Codewhale 0.10.2 or older: once the folder upgrades it can no longer save sub-agent state (Refs #7232).
+- **A held coordination lock no longer makes a new session read-only.** When another session owns the delegated-agent store, the new session starts on private state and says so, instead of refusing every sub-agent with “Failed to clean up sub-agents”.
 - **A dev server can outlive the turn in an interactive session.** `persist:true` now works in the TUI and desktop when the thread has Full Access; restricted postures and Fleet/sub-agents still refuse it.
 - **`codewhale exec --add-dir <path>`** (repeatable) and `addDirs` on `POST /v1/threads` let the file tools read and write a sibling directory, a second checkout or a shared scratch root without turning on Full Access.
 - **Unsettled usage is persisted in production, not only in tests.** The interactive sink now records a legacy usage receipt when a provider response has no settlement, so children and turns stop reporting settlement failure.

 - **A local proxy that stops mid-session no longer strands the session (#7231):** the model, catalog, search, vision, finance, MCP-registry, profile and remote-control clients watch a loopback proxy port and go direct while it refuses connections, then resume proxying when it returns.

Set `CODEWHALE_LOCAL_PROXY_FALLBACK=0` to keep the old build-time snapshot.
 - **Proxy diagnostic privacy ([#7233](https://github.com/codewhale-hq/codewhale/issues/7233)):** malformed MCP proxy warnings omit configured values; local-proxy log labels mask userinfo and omit URL paths, queries and fragments.

CodeWhale BotandClaude Sonnet 5.5	4c46ba7f4d	test(engine): expire the dropped-dispatch deadline only after the client call is entered (CW-8127) The dropped-dispatch test gave the nested call a real 100 ms deadline. On a slow runner that deadline could expire before bind_dispatch settled the unknown-usage record, so the biased wall-clock select won with zero records (left: 0, right: 1). Give the call a 600 s deadline, wait until the fixture client is entered (the record is settled before the client is called), then pause tokio time and advance 601 s so the deadline always fires after dispatch. The wait selects on entered against the dispatch with a panic if the dispatch ends first, inside a 10 s real-time timeout, so a regression that stops the dispatch before the client fails at once instead of hanging. Every assertion is unchanged. Product code is unchanged. nextest stress 40/40 passed, 6 tests per iteration, target test 40/40 (farm run 20261112T113538Z-cw8127r1-new-33edc8); the old test under the same stress failed 1 of 20 at left: 0 (farm run 20261112T104528Z-cw8127-old-7569e0). clippy -p codewhale-engine --all-targets --all-features -D warnings clean (farm run 20261112T113538Z-cw8127r1-clippy-373b1e); cargo fmt --check and scripts/preflight.sh --check OK.

CodeWhale BotandClaude Sonnet 5.5	6bbdf3de40	feat(app-server): one read route lists every plugin kind (CW-8049 PL-02) GET /v1/apps/plugin-index projects the plugin registry, the built-in switch catalog, skills, connectors, hooks and hand-written commands into one list with kind, source and state. Each item embeds the row its owner's route returns by calling that owner's handler, so a field an owner adds appears here without a second edit; an owner that fails is named under unavailable and the rest still list. A plugin item carries the names of the skills, connectors, hooks, commands and profiles it adds, and those are not listed again as items. Replaces nothing; the owners keep their routes. A user command row now says which plugin added it (UserCommand.plugin, CommandCatalogEntry.plugin, filled from the registry's plugin authority), so a plugin's markdown command is not shown as hand-written. The wiring in runtime_api.rs (mod line, route line, that field) and the command_catalog and tui hunks are separable from plugin_index.rs.

CodeWhale BotandClaude Fable 5.2	d0214e50c1	refactor(catalog): one model listing for both commands, and the inventory stops judging windows by name With the readings proved equal on one captured catalog, the second copies go: - `route_preferences::list_models` no longer assembles its own roster (catalog rows, saved default, sort, dedup). It calls `provider_lake::listed_models_for_route`, the same function `models` prints. - The routing inventory no longer asks the bundled catalog whether a model name has a context window to decide if a number is verified. The resolved route's own source decides; a route that does not resolve is unverified. Farm (Linux x86_64), this commit: catalog_parity 1 test run: 1 passed; config and engine lib tests filtered `catalog model pricing cost_status route`: 1316 passed, 0 failed; clippy -D warnings for config and engine (all targets, all features) and for cli and app-server (all targets): clean.

CodeWhale BotandClaude Fable 5.2	57a2044d58	fix(catalog): both model commands, the Runtime API, routing and cost read one captured catalog the same way The new check loads one captured Models.dev catalog (the bundled seed, sha256 7c48830c…d256) and an id-only Anthropic roster into a sealed home, then reads three routes through `model list` / `model resolve`, `models`, `GET /v1/providers/{id}/models`, the routing inventory and the cost envelope: the official Anthropic route, a custom endpoint serving a same-named model, and the Z.ai plan endpoint. It prints every reading and fails on any disagreement. On the previous source it found three: - `model list` skipped a custom endpoint unless its table was literally named `custom`. It now lists every configured custom route under the route's own name. - `model resolve` refused a custom endpoint's saved model ("no registered model") because the legacy registry was asked about an endpoint that owns its own roster. The registry is no longer consulted for those routes; the route resolver and a fetched roster still decide. - The routing inventory gave a custom endpoint the context window and output limit of a same-named model and marked the window verified. It now takes the window, its source and the output limit from the resolved route, so a borrowed number is marked unverified and an unpublished output limit stays unknown. `provider_lake::listed_models_for_route` is the list body of `models` moved out unchanged so the check can read it. One spelling difference is left and reported, not asserted: the inventory normalises a listed `glm-5.1` to `GLM-5.1`. One disagreement is also named, not hidden: a custom endpoint has no published window, so routing still reports 200,000 for a saved model whose name matches a known one (the router's long-context tag reads it), marked unverified, while the Runtime API reports unknown. The check records the Runtime reading as unknown and allows exactly that pair as a known difference; any other window disagreement fails. The check also pins the charge side: a custom endpoint gets no charge (`UnknownBillingBasis`); the Z.ai plan route gets no charge (`NotMoneyMetered`) even for a model that has a list rate, and both surfaces show that same list rate; an id-only first-party model with no price row reads unknown on both surfaces and produces no charge. Farm (Linux x86_64): config, engine and app-server lib tests filtered `catalog_parity catalog model pricing cost_status route`: 1444 passed, 0 failed; clippy -D warnings for config, engine, cli and app-server (all targets, all features): clean.

CodeWhale BotandClaude Sonnet 5.5	c33d911e74	fix(acp): a plugin tool's nested approval reaches the editor as a permission request that names the nested tool (CW-8050) When a plugin tool asks the core to run a tool that needs approval, the ACP projection resolves the nested execution id to the admitted plugin call and shows the request on it. The request is built from the approval.required payload (nested tool name, input, summary) so title, kind and rawInput show what is being approved, and it carries no status so the running plugin call is not reset to pending. The gates test and journey test live in acp_journey and assert the second request names write and carries nested.txt.
