docs: record superseded transcript collapse PR

 | #2736 sub-agent model inheritance | Locally harvested with explicit-override and provider-shaping tests. | Tool-agent routing now inherits the parent runtime model instead of hard-coding `deepseek-v4-flash`, while explicit DeepSeek-style tool-agent overrides still win. The `reasoning_effort = off` fast lane is covered by strict OpenAI-like provider request-shaping tests. Credit @h3c-hexin; comment/close the original after the integration branch is public. |
 | #2737 configured `skills_dir` discovery | Locally harvested with explicit-config precedence. | The system prompt now unions workspace-discovered skills and configured `skills_dir` skills instead of treating the configured directory as a fallback. Explicit configured skills are inserted before global defaults so they are not lost behind a large global skill library. Credit @h3c-hexin; comment/close the original after the integration branch is public. |
 | #2738 dense tool-call transcript collapse | Locally harvested with expansion, cache-key, and safety fixes. | Successful read/search/list-style tool runs collapse by default once they cross the density threshold; failures, running cells, shell/exec, patch/write/edit/delete, diff preview, plan update, and review cells stay visible. Users can expand a group with Enter/Space/mouse and can set `tool_collapse = "compact" | "expanded" | "calm"`. Credit @idling11 and issue #2692; comment/close the original after the integration branch is public. |
+| #2740 dense tool-run collapse follow-up | Superseded by the local #2738 harvest. | The PR carries the same #2692 product direction but its reviewed head still depended on folded-thinking state before collapse could render and omitted MCP status/name handling. The local #2738 harvest already covers common-case collapse, MCP success/tool-name grouping, expansion/cell-map behavior, and `tool_collapse` modes with focused transcript-collapse tests. Credit @idling11; comment/close after the integration branch is public. |
 | #2734 sidebar detail popovers | Locally harvested as the mouse-hover slice for #2694. | Work/Tasks/Agents hover metadata now stores row hitboxes, compact display text, and full source text so truncated checklist items, task/turn ids, and sub-agent ids/progress expand into a bordered wrapping popover. The harvest fixes reviewer risks from the PR by treating row metadata as authoritative, sizing by display width instead of bytes, and keeping source text untruncated. `cargo test -p codewhale-tui --bin codewhale-tui --locked sidebar_hover -- --nocapture`, `... work_hover_text_preserves_full_checklist_item ...`, and `... subagent_hover_text_preserves_full_agent_id_and_progress ...` passed. Credit @idling11; keep #2694 open for keyboard access, richer Work/Tasks/Agents metadata, redaction expansion, and clipping/snapshot coverage. |
 | #2532 pending-input delivery-mode labels | Locally re-harvested for #2054. | Pending-input preview rows now label steer-pending, rejected-steer, and queued-follow-up delivery modes, and wrapped continuation rows align under the label. `cargo test -p codewhale-tui --bin codewhale-tui --locked pending_input_preview -- --nocapture` passed. Credit @cyq1017; #2054 remains open for cancel/edit-mode affordance clarity. |
 | #2029 sub-agent checkpoint continuation | Locally implemented as the live-timeout recovery slice. | Sub-agents now persist `SubAgentCheckpoint` metadata through state, results, projections, and transcript handles. The runner checkpoints local messages before API calls and after model/tool cycles; per-step API timeout marks the child interrupted with `continuable=true`; `agent_eval { continue: true }` resumes only live checkpointed interrupted children. Reload preserves checkpoint metadata, but cold-restart continuation is intentionally not claimed because the child task/input channel is not rehydrated yet. `cargo test -p codewhale-tui --bin codewhale-tui --locked subagent -- --nocapture`, `cargo fmt --all -- --check`, `git diff --check`, and `cargo clippy -p codewhale-tui --locked -- -D warnings` passed. Credit @qiyuanlicn for the recovery report; keep #2029 open only if cold-restart continuation or broader checkpoint UX remains required. |
