 ## Outcome
 
 - Canvas implementation complete: Agents-style navigation/composer/Markdown, 64px identity header, resizable 42/58 workspace, current output preview and historical selection, one persistent editable production card, <=899px compact panel switching. Hidden videos pause; modal Escape does not change split focus; compact creation no longer opens two dialogs.
-- Coordinated integration, normal main push, live temporary-application update and worktree retirement remain pending. Code-navigation chat completed source d287d5ac; its live verification is blocked by Mac lock. Channel-adapter chat still running. Required unlock question is pending; no app mutation has occurred in this task.
+- Coordinated integration, normal main push, live temporary-application update and worktree retirement remain pending. Canvas source2ca6e31; Code-navigation chat completed product source d287d5ac (handoff15848cd). The committed effective Renderer non-project-doc delta from baseline70166d2 was applied through Git three-way merge, preserving Canvas and all current Sidebar/TOOL/SKILL/knowledge-upload fixes; its live verification is blocked by Mac lock. Channel-adapter chat completed source979596f. Its non-project-doc product/test/README delta was also three-way merged cleanly. Combined checks are in progress; no Yuxi files were changed. Required unlock question is pending; no app mutation has occurred in this task.

-- Target: Canvas presentation summary in current-state / ADR-007. Proposal: retain the sole cloud-owned Living Form and generation contract while presenting its only editable card in the works pane, with remembered split/compact tabs and large output preview. Evidence: source changes, 126 focused units, two fixture Electron flows and screenshot QA. Future impact: keep drafts mounted across panel switching and avoid reintroducing fixed 256px result rails. No semantic conflict with authority rules; user approved the presentation change. Canonical updates require serialized integration and are not written by this feature task.
