Shkarko CodeWhale 0.8.43

Fixed
- grep_files now respects the cancellation token. Long-running file searches cancel promptly instead of running to completion after the user aborts (#1839). Thanks @LING71671.
- npm installer stream-pause race condition fixed. The install script now pauses HTTP response streams immediately, preventing early data loss that caused "Invalid checksum manifest line" errors (#1860). Thanks @jeoor.
- Ctrl+Z restores the last cleared composer draft. Pressing Ctrl+Z in an empty composer recovers the text that was last cleared with Ctrl+U or Ctrl+S, matching the muscle memory users expect from other editors (#1911). Thanks @LING71671.
- Clipboard works on non-wlroots Wayland compositors. The Linux clipboard path now tries wl-copy before arboard, fixing silent copy failures on niri, River, cosmic-comp, and GNOME mutter (#1938). Thanks @ousamabenyounes.
Added
- Goal mode ships as a persistent objective surface. Orthogonal to Plan / Agent / YOLO execution modes. Use /goal <objective> to set a goal, /goal done to mark it complete. Goal status appears in the Work sidebar with elapsed time. Alt+G toggles Goal mode; /mode goal or /mode 4 activates it from the command line (#1976).
- Post-turn receipts cite evidence for every completed turn. When a turn finishes, a receipt line shows in the transcript tail with a summary of tool calls, file changes, and evidence that supports the agent's claims. Tool evidence is collected per-turn and flushed on new dispatch.
- Stall reason classification. When a turn has been running for more than 30 seconds, the footer now appends a classified reason: "waiting for model", "tools executing", "sub-agents working", "compacting context", or "waiting — no recent activity".
- Decision card widget for structured user input. When Brother Whale needs a choice, it surfaces a bordered card with numbered options, keyboard navigation (1-9 / j/k / arrows), and Enter/Esc to confirm or cancel.
- Tasks sidebar now shows fuller turn IDs and supports copy-to-clipboard. Turn ID prefixes are widened from 12 to 16 characters for disambiguation, background job status is presented as "X running, Y completed" instead of ambiguous "X active (Y running)", and y / Y yank affordances copy the current turn ID or full status line to the system clipboard (#1975).
Changed
- Contributor count and acknowledgement surfaces refreshed. The website fallback contributor count now reflects 98 live GitHub contributors (up from the stale 91). All three README translations (English, 中文，日本語) now include 30+ previously unlisted contributors whose PRs were merged since April 2026.
- README and web surface rebrand refinements. Crate descriptions, npm package text, and website copy now consistently position CodeWhale as open-model-first and provider-spanning, with DeepSeek V4 as the first-class path.
- New contributor names added to README acknowledgements. Thanks to @Apeiron0w0, @aqilaziz, @ChaceLyee2101, @ComeFromTheMars, @CrepuscularIRIS, @dst1213, @eltociear, @fuleinist, @greyfreedom, @h3c-hexin, @heloanc, @hxy91819, @J3y0r, @JiarenWang, @jinpengxuan, @KhalidAlnujaidi, @laoye2020, @lbcheng888, @linzhiqin2003, @Liu-Vince, @lixiasky-back, @pengyou200902, @punkcanyang, @Rene-Kuhm, @SamhandsomeLee, @sockerch, @sternelee, @Wenjunyun123, @whtis, and @wuwuzhijing for the translations, typo fixes, docs polish, and small UX improvements that landed across the 0.8.42 → 0.8.43 cycle.
Security
- Thinking blocks can be collapsed/expanded via keyboard. Space on an empty composer toggles the focused thinking cell between collapsed and expanded, complementing the existing mouse right-click context menu (#1972).
- Sub-agent completion events no longer delayed to the next turn. The turn loop now drains late-arriving sub-agent completions at the final checkpoint before breaking, so child-agent sentinels surface immediately instead of appearing in the following turn (#1961).
- codewhale doctor now referenced correctly in SSE timeout errors. The error message shown when SSE streams fail to connect now points users to codewhale doctor (not the legacy deepseek doctor).
