CHANGELOG.md

@@ -7,7 +7,51 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ## [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.
+- **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 a plain-text summary accompanies each chart for the model and other clients. 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.
+- **Paused stream:** A paused stream now shows the thinking it has already received instead of waiting for the next token.
+- **Sign-in notice:** The "Account not loaded" notice now appears once per sign-in in the footer, and Esc dismisses it; it no longer lands in the transcript.
+- **Usage reporting:** Installers now run their closing diagnostic with usage reporting and update checks off and print how to turn usage reporting off. `codewhale doctor` now says a saved opt-out comes from the config file, not the environment, and help and English notices call the feature "usage reporting".
+- **Long tool names:** Tools whose encoded name is longer than the route's limit are now left out with a visible warning instead of failing every request with a 400. The limit is 64 characters on OpenAI and on other OpenAI-compatible providers that document no larger limit, and 128 on Anthropic-style routes, DeepSeek, Ollama, Ollama Cloud, vLLM, SGLang and custom routes. Forcing such a tool gives an error that names the tool and the limit, and a session that already called one on a route with a documented limit (Anthropic, OpenAI, Codex, DeepSeek) is refused with a message saying to switch route or start a new session. A forced tool_choice in any chat form now names the encoded tool, and a tool whose real name looks like an encoded escape can no longer be mistaken for another tool.
+- **Start after a hard kill:** The Engine now also starts after a hard kill when its home was spelled through a symbolic link (for example under /tmp on macOS) or, on macOS and Windows, in a different letter case: a dead owner's record for the deleted data directory is discarded instead of refusing every start.
 - **Context window labels:** the model picker and fleet capability badges now show `1.5M` and `2.1M` for 1,500,000- and 2,100,000-token windows instead of `1.50M` and `2.10M`. Thanks [@Aboysky](https://github.com/Aboysky) (PR 7295).
 - **REPL output limit:** REPL output is now cut to its byte limit, so Chinese, Japanese, Korean or emoji output no longer comes back up to three times longer than the limit, and the cut never splits a character. Thanks [@Aboysky](https://github.com/Aboysky) (PR 7296).
 - **Git status with renamed files:** the Git and Changes views no longer fail with "git status failed" or show a phantom row when a file is renamed on the worktree side (for example a moved file marked with `git add -N`), including when the original name starts with non-ASCII text such as Chinese. Thanks [@luochen211](https://github.com/luochen211) (PR 7310).

 - **Simplified Chinese punctuation and /status:** in the zh-Hans interface, the `/router` setup and test screens, label prompts and usage lines now use full-width punctuation (`：；，（）`) instead of ASCII marks next to Chinese text, and `/status` values start in one column under Chinese labels instead of starting at a different column for each label. Thanks [@luochen211](https://github.com/luochen211) (PR 7314).
 - **Git tool on older git:** the Git tool's `review_scope` action no longer passes `--no-lazy-fetch`, which git older than 2.44 rejects, so it failed on every call there. It sets `GIT_NO_LAZY_FETCH=1` instead, which keeps the same protection on newer git and is ignored by older git.
 - **Plugins from a shell:** `codewhale plugins trust <name>` prints the same capability review as `/plugin trust` with its bundle review token and, in a terminal, asks once. `--review-token <token> --yes` trusts without a prompt while that token still matches the installed content and capabilities; the token ties trust to the exact content, does not show that anyone read the review, and is not the host-service review token. A `--yes` trust is recorded as the command line and grants no host service. Every command the agent runs (shell, persistent terminal, verifier and test runs, the Python kernel, MCP servers it starts) now carries `CODEWHALE_AGENT_PROJECT` with the session's project, while hooks and configured MCP servers do not; with it, a trust or enable is recorded as the agent's, for that project only, even when a prompt is answered through a terminal, and the agent may trust only a plugin it installed from a folder inside the project. `plugins enable`, `disable` and `revoke` work the same way, each with `--json`, and `plugins status` shows who approved. The agent's shell commands that run them go through the session's approval like any other shell command, so a Full Access agent can trust and enable a plugin it wrote; the mark is a label the agent could remove in Full Access. (CW-7891)
-- **Sandbox:** a managed configuration can set `tool_launcher` (Linux) to run every sandboxed tool command as another user, in front of bubblewrap; commands then run inside the sandbox or not at all, masks are computed for that user, `/tmp` is private per command, and `GET /v1/runtime/info` reports `sandbox.kind` and `sandbox.tool_launcher`. Without the key nothing changes. A managed configuration named by `CODEWHALE_MANAGED_CONFIG_PATH` is now applied on every load; a configuration whose provider comes from a plugin no longer loads with the managed file skipped, it fails to load instead.

Without the key nothing changes. A managed configuration named by `CODEWHALE_MANAGED_CONFIG_PATH` or `managed_config_path` is applied on every load, and one that is missing or cannot be read stops the load instead of loading with no managed layer; a blank `CODEWHALE_MANAGED_CONFIG_PATH` is now ignored instead of switching the managed layer off, and a config file's `managed_config_path` can no longer point away from an existing file at the default managed path. Fleet local workers inherit the managed-config variable, and `codewhale serve --mcp` does not expose shell tools when the managed configuration it loads sets `tool_launcher`. A configuration whose provider is declared only by a plugin fails to load under a managed configuration, with an error that says to declare the provider table or pick a built-in provider.
 - **Receipts:** a terminal session's receipt (`/receipts`, `codewhale receipts`) now shows the provider's token counts and the same cost report `/cost` prints, saying "unknown" and why when the route's price is not known, never a guess. A Runtime thread's receipt shows token counts only; its cost line follows in a later release. `codewhale metrics` now counts usage saved in terminal sessions instead of reporting none. Sessions saved by 0.10.2 carry only a combined token total.
 - **ACP server on the official SDK:** The ACP server (`codewhale serve --acp`) now runs on the official Agent Client Protocol SDK. Its messages follow the official v1 types, and it no longer advertises the non-standard `modelSelection` capability or session `models` field. Session list entries carry `createdAt` and `messageCount` under `_meta.codewhale`, terminal sign-in methods are advertised only to clients that enabled terminal authentication, a notification is never answered, a permission request always carries text, and session list and configuration requests are served while a turn runs, response ids are echoed unchanged for every client (the Zed-only string rewrite is gone), and `initialize` without `protocolVersion` is refused with `-32602`.
 - **External agents over ACP:** Codewhale now drives external agents through the official Agent Client Protocol SDK. Request ids on the wire are strings, and an agent's error is treated as a sign-in problem only when it carries the protocol's auth-required code.

+- 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.

Generated protocol and SDK exports keep LF line endings in Windows checkouts.
-- **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”.
+- **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 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.

Only a definite refusal from every resolved address changes the route; remote proxies, `NO_PROXY` matches, credentials and the existing precedence are unchanged. Set `CODEWHALE_LOCAL_PROXY_FALLBACK=0` to keep the old build-time snapshot.

-//! Session tree journal placeholder (issue #5262).

-//! The journal is append-only with an in-memory tree projection:
-//! every non-header entry carries `id` + `parentId`, the active position is
-//! a `leafId`, appending creates a child of the leaf, and branching only
-//! moves the leaf — it never rewrites history. This file lands the entry
-//! shape that #5262's tree operations hang off of; compaction and
-//! branch-summary entry kinds are included as first-class kinds but their
-//! *strategies* are deferred.
-//!
-//! Re-exports the protocol journal as the canonical shape so `protocol` and
-//! `core` agree on the wire. `core` adds the `SessionJournal` wrapper that
-//! owns the `current_leaf_id` column in `state.threads`.
