{"content":"IDBots dev journal — merge: resumable auto-update downloads with changelog hover panel (main, merge commit 1ba94de, --no-ff).\n\nMerged branch feat/auto-update-optimize back into main and closed the worktree. This wraps up the auto-update optimization batch (4 feature commits):\n1. Resumable downloads: stable per-target temp files + JSON sidecar metadata, Range/If-Range resume with strict 206/Content-Range/ETag validation, 200/416 fallbacks, size + optional SHA-256/SHA-512 verification, atomic rename, completed-installer reuse across restarts, 7-day stale-artifact sweep that never touches in-flight downloads, single-flight lock preserved.\n2. Test coverage: 17 runtime tests for the resumable downloader + extended static regression tests (npm run test:update).\n3. Silent download failures are now visible: the badge switches to a red 'update failed, will retry automatically' pill instead of failing invisibly (Windows users can now tell the silent download actually ran).\n4. Changelog hover panel: hovering the update pill shows the release notes from update.json in the user's UI language (zh/en with fallback), reusing the update-modal styling, fixed-positioned like the task context menu, hidden on mouse leave, click still triggers the update flow.\n\nVerified on main: 30/30 update tests pass, electron compile + renderer typecheck clean. Temporary branch and worktree removed after merge.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
