- engine: Remote gains missing_chunks, put_chunk and put_chunked; upload_chunked streams a big file in 4 MiB chunks, sends only the chunks the server lacks, retries with backoff and reports progress (SyncStatus.transfer); the scan hashes by streaming and skips only files over 1 GiB
- engine: server.devices command and a sync.attachments option (non-Markdown files are skipped when it is off)
- ui-egui: the sync pill opens a bottom sheet on a phone-width window (status, devices, conflicts row, options, Sync now); wider windows keep Settings > Sync
- tests: chunk resume against the real server, 6 driven sheet tests, devices stub tests
Verified with cargo xtask ci (fmt, clippy -D warnings, workspace tests, layers, tree, i18n).
