ci: read main's sccache on every run, write it only from main

The sccache install step now runs on every event in ci.yml and
ci-test-suite.yml, and each Enable sccache step sets
SCCACHE_GHA_RW_MODE to READ_WRITE only on refs/heads/main and READ_ONLY
everywhere else (sccache docs/GHA.md; the action installs the latest
release, v0.19.0). Pull request and branch-dispatch runs, which now run
the full sharded suite, get main's compiler cache hits without writing
the refs/pull/N entries that once pushed the repo past its 10 GiB cache
cap. rust-cache save-if stays main-only and the Windows RUSTC_WRAPPER
guard from MAIN-GREEN is unchanged.

release-workflows.test.js now checks, per file, that every sccache
enable carries the off-main read-only switch and that no sccache install
is gated on main; both checks were confirmed to fail on a mutated copy.

Windows test legs keep debug 0: no test asserts on backtrace content
(only RUST_BACKTRACE pass-through lists and compile-time
Location::caller, which debug info does not affect).

Checks: node .github/scripts/release-workflows.test.js passed (211
paths, 11 wrapper cases x 12 steps, 15 hermetic checks, workflow
contracts); actionlint 1.7.12 with the repo's CI args (-ignore SC2129
-ignore SC2221 -ignore SC2222) clean on all workflows;
scripts/test_ci_migration_wiring.py 19 tests OK.

First drafted by a duplicate agent run in this worktree; reviewed and
tightened here.

CHANGELOG.md

@@ -11,11 +11,9 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **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).
 - **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.
-- **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.

crates/tui/CHANGELOG.md

@@ -11,11 +11,9 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **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).
 - **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.
-- **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.

 `/mode plan`. `operate` and its spellings still parse, as Work, and say that
 Operate was retired, so an older setting or script never errors.
 
-The picker has two groups. **Conversation mode** lists the modes the Engine
-offers, Standard mode and Creator mode, each with a one-line description; a
-mode that cannot be used yet is listed, disabled, with its reason. **Permissions**
-holds Work and Plan, still on `1` and `2`; the conversation modes have no
-number keys. A conversation's mode is chosen before its first message and is
-fixed after it: `/mode creator` or the picker's first group changes a blank
-conversation in place, and after the first message the picker shows the group
-as locked and `/mode creator` is refused with a note to start a new
-conversation. `/new` starts a Standard conversation, `/new creator` starts a
-Creator mode conversation (`--force` still combines). Resume, `/load`, `/fork`
-and `/clear` keep the conversation's saved mode, and the mode name appears in the
-footer when it is not Standard. A mode never changes a permission: Creator
-mode in Plan is still Plan. `codewhale` and `codewhale exec` take
-`--conversation-mode <MODE>` to start a new session in a mode; with `--resume`,
-`--session-id` or `--continue` it must match the session's saved mode, or the
-run exits with code 2 before any model call.
-
 - **Plan**: design-first prompting. The stable primitive names remain familiar, but the runtime centrally refuses file mutation and shell execution. Read-only inspection and policy-allowed research, including deferred Web search/fetch, remain available. When a Plan turn successfully finishes a nonempty response, including a prose-only plan, the TUI asks how to continue: Work (Ask), Work (Accept Edits), Work (Auto-Review), or keep planning. Work sends the exact approved response as a normal follow-up and preserves that turn's existing To-dos, or adds one pending plan item without replacing unrelated work.
 - **Work** (internally `agent`): ordinary multi-step execution. The first-turn toolbox includes `read`, `write`, `edit`, `file_search`, `grep_files`, `bash`, `agent`, `todo_write`, `present`, and `load_skill`, plus `create_goal`, `get_goal`, `update_goal`, and `task_shell_wait` so goal and background-shell controls are available without discovery. The agent calls `create_goal` when a request is a durable objective; the host never infers a goal from wording, and the contract must not tell the model otherwise. Approval, sandbox, repository law, and managed policy decide what may execute.
 - **Operate is retired.** It was Work with an orchestration contract, and that contract now lives in every session's constitution: make a goal of a durable request, keep the plan visible, fan independent work out to parallel sub-agents, and have an independent reviewer try to refute a non-trivial change. A saved `default_mode = "operate"` loads as Work and says so once; a Runtime API request with `mode: "operate"` runs as `agent` with the default posture (Accept Edits) and logs one notice per process, never an error. Agents forked from an older Operate conversation do not inherit its contract. Multi-agent work stays on `agent`, `workflow` and `/fleet` in every mode.

 ## Unreleased — 0.2.0
 
-- Add data displays: `DataSparkline`, `DataBars` and `DataTrend` (a braille
-  line chart). The words carry every value; the ink draws in from a caller
-  progress (`MotionStep::drawn`) and is at its end state under reduced or
-  still motion. Bars glide from their previous values.
-- Add `DataDisplay`, the same displays as JSON an agent can send:
-  `DataDisplay::from_json` validates it (finite numbers, at most 1024 points
-  or 24 bars, labels up to 120 characters), `describe` says the same facts as
-  plain text, and `DATA_DISPLAY_SCHEMA` is its tool schema. Try
-  `cargo run --example data`.
-
 - Reexport the shared avatar contract from Codewhale Protocol. Rendering and
   artwork stay in this library. Protocol 0.10.3 registry proof must precede
   this package publication.
