@@ -11,7 +11,6 @@ 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).
- **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) (PR 7293).
 - **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.

 - **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).
- **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) (PR 7293).
 - **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.

-`source` is `SessionSource` (`crates/state/src/lib.rs:34-41`) stringified by `session_source_to_str` (`:1909-1917`): `interactive | resume | fork | api | unknown | ci`.
+`source` is `SessionSource` (`crates/telemetry/src/event.rs`), a closed enum declared in the telemetry crate: `interactive | resume | fork | api | unknown | ci | fleet_worker | agent | scripted`.
 `ci` replaces the others whenever `CI` or `GITHUB_ACTIONS` is set to a true
 value, including the Codewhale GitHub Action, so automated runs are never
 counted as people. Only that boolean environment fact is read.

+`fleet_worker`, `agent` and `scripted` separate automated `exec` sessions from
+people. `fleet_worker` is an `exec` that Codewhale's own fleet dispatcher
+started, `agent` is an `exec` started from inside an agent's shell command (only
+the presence of a Codewhale-owned environment variable is read, never its
+value), and `scripted` is an `exec` whose standard input or output is not a
+terminal. When more than one applies the order is `fleet_worker`, `agent`, `ci`,
+`scripted`. Other surfaces are unchanged.
+
+`install_age` is `new_today | under_week | older | null`: a coarse bucket of how
+long this installation has existed. It is computed on your device and only the
+bucket leaves it; the date it comes from is stored only in the local state file
+and never leaves the device. The same UTC day is `new_today`, 1 to 6 days is `under_week`, and 7 or more is `older`. An installation whose state predates this field reports `older`, never `new_today`. `null` means the local state could not be read.

 ## 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.

CodeWhale Bot	d7cadafbab	wip: client schema 6 contract (S6-C)	2026-11-12 20:00:57 -08:00
CodeWhale BotandClaude Sonnet 5.5	f03f69e086	chore(telemetry): collector accepts runtime schema 6 and keeps schemas 1 to 5 Schema 6 (notice 8) carries the exact key sets the client slice will send: model_usage counters gain requests, reasoning_tokens and generation_secs, and model_usage gains a context object of four input-size request counts; the session_start event gains install_age; exec sources gain fleet_worker, agent and scripted; exit_class gains unclean. Each is accepted on v6 only, so a v1 to v5 batch is validated exactly as before and a v4 batch carrying any v6 key or value is still refused. The preUsage shortcut becomes one explicit boolean per version. Rows append: model_usage double12..18 (0 on v4 rows, blob19 tells them apart) and install_age in blob12 of session_start rows. generation_secs is a whole-second session sum rather than milliseconds, so a one-request session does not reveal an exact request duration. PostHog forwarding is untouched, so v6 stays first-party only. report-funnel reads v4 and v6 model usage and excludes fleet_worker, agent and scripted starts as it does ci. A hand-authored crates/telemetry/tests/golden/v6.json is the contract fixture. The doc-welded constants (SCHEMA_VERSION, EVENT_FIELDS, SESSION_SOURCES, EXIT_CLASSES) stay at their v4 values until the client slice updates docs/TELEMETRY.md; the v6 sets are separate constants. Checks: telemetry-ingest npm test 225 passed 0 failed (8 files), tsc --noEmit clean, wrangler dev --local answered 204 to v4.json and v6.json and 400 to a v6 batch with a free-text install_age, wrangler deploy --dry-run ok, cargo fmt --all -- --check ok, scripts/preflight.sh --check OK.

CodeWhale BotandClaude Opus 5.5	622a493078	feat(tui-kit): animated data displays an agent can send as JSON (CW-8202) The vendored terminal kit could move things (MotionStep, MotionPolicy) but had nothing that shows numbers. This adds three displays and a data description of them: - DataSparkline: one row, newest values on the right, with now/min/max in words. DataBars: a titled list of bars in eighth-cell steps that grow with a stagger and glide from previous values. DataTrend: a braille line chart with its range on the axis; it draws in from the left with a body-ink pen and falls back to a sparkline when too small. - Every value is in the words, so colour and ink never carry a fact alone, and ASCII and NoColor profiles keep the rules. Draw-in reads a caller progress from the new MotionStep::drawn, so reduced and still motion paint the end state and the kit still never reads a clock. - DataDisplay is the same vocabulary as serde JSON, borrowing the UI SDK idea (vercel-labs/ui) that a component says what it is and holds as data so an agent reads and writes facts, not pixels. from_json validates at the trust boundary (finite numbers, <=1024 points, <=24 bars, labels <=120 chars, trend rows 3..=16); describe() gives the plain-text facts; DATA_DISPLAY_SCHEMA is the tool schema. - Gallery entries (6), examples/data.rs (live dashboard, --json FILE for an agent-sent display, --text, --svg DIR), CHANGELOG and COMPONENTS rows. Not in this slice: an Engine tool or transcript event that lets the model emit a DataDisplay. README's gallery count (199) and rendered previews are not regenerated for the 6 new entries. Checks (kit crate, standalone target): cargo test --lib 137 passed, 0 failed (13 new in components::chart, incl. rule checks over 9 profiles x 40/80/120 cols and an insta snapshot); cargo test --doc 11 passed; cargo clippy --all-targets -D warnings clean; cargo fmt --check clean. No Engine crate glob-imports the kit or uses the new names; Engine build not run locally, CI covers it on landing. Co-Authored-By: Claude Opus 5.5 <[email protected]>	2026-11-12 18:11:16 -08:00
CodeWhale BotandClaude Opus 5.5	8aa7707d04	fix(web): list MannXo with the post-0.10.3 contributors and drop the duplicate Qwen Code line (CW-8181) `5d7ca06a5a` added @MannXo to RELEASE_CONTRIBUTORS, the website's 0.10.3 credits, but #7293 landed after 0.10.3: docs/CONTRIBUTORS.md lists MannXo in "Unreleased — landed after v0.10.3", and the 0.10.3 "### Contributors" ledger in CHANGELOG.md does not name them. public-copy.test.ts ("keeps current-release website credits in exact changelog parity") then failed, which failed the Lint & Type Check job of web.yml run 43344178264 and skipped the Cloudflare deploy. MannXo moves to UNRELEASED_CONTRIBUTORS beside SamhandsomeLee, matching the contributor doc. The same commit meant to rewrite the Qwen Code changelog line with (#7293) but added a second copy; the old "(PR 7293)" line is removed from CHANGELOG.md and crates/tui/CHANGELOG.md, keeping the (#7293) form the release-note receipt check looks for. Evidence (web/, worktree claude-CW-8181b, on `97c1ad923d`): - public-copy.test.ts: passes (part of 5 files, 109/110; the one failure is ratatui/catalogue "Test timed out in 5000ms" with load average ~60) - npm run check: exit 0 (facts OK, docs PASS, runtime routes 243 PASS, next build 979/979 static pages) - npm test: 1303/1306; the 3 failures are 5 s timeouts in public-installer-contract and ratatui/catalogue that move between runs under that load, in files this change does not touch - scripts/check-contributor-credit.py: "Every contributor in the window is credited on all three surfaces."
