Recent decisions affecting current work: - Phase 1 starts with state ownership fixes before UI consolidation to eliminate poll-driven draft overwrites first. - This milestone stays brownfield and must preserve working lifecycle, model selection, and chat flows while improving runtime workspace trust. - [Phase 01]: Kept legacy snapshot and saveConfig outputs while adding explicit draft APIs so existing runtime drawer consumers keep compiling during the Phase 1 transition. - [Phase 01]: When a runtime draft is dirty, polling updates only operational live fields and leaves baseline plus draft config untouched. - [Phase 02-lifecycle-command-safety]: Expose active and last lifecycle command data on RuntimeSnapshot so frontend polling can render trustworthy lifecycle feedback without inferring from status alone. - [Phase 02-lifecycle-command-safety]: Centralize duplicate start/stop blocking in runtime state helpers so save, start, and stop flows share the same command-result contract. - [Phase 02-lifecycle-command-safety]: Keep restart-required save enforcement limited to connection_mode, model_path, addr, gpu_layers, and ctx_size to stay aligned with the existing backend runtime boundary. - [Phase 02-lifecycle-command-safety]: Mirror backend lifecycle metadata directly into the frontend RuntimeSnapshot so polling and command responses share one contract. - [Phase 02-lifecycle-command-safety]: Derive applyImpact from saved baseline versus draft config using the backend restart-required field list instead of UI-only heuristics. - [Phase 02-lifecycle-command-safety]: Expose activeLifecycleCommand, lastLifecycleResult, and lifecycleBusy from the manager so status-card and drawer copy can consume explicit state in plan 02-03. - [Phase 02-lifecycle-command-safety]: Use explicit lifecycle result banners instead of overloading last_error so completed and blocked actions remain visible after polling refreshes. - [Phase 02-lifecycle-command-safety]: Render apply guidance in the drawer before the CTA row so users see whether a draft applies immediately, needs restart, or must be saved before apply. - [Phase 02-lifecycle-command-safety]: Keep status-card and drawer props backward-compatible with optional lifecycle fields while Sidebar forwards the new manager contract. - [Phase 03-01]: Reuse existing restart-impact field list and lifecycle labels instead of creating parallel heuristics - [Phase 03-01]: Derive diagnostics from backend-owned snapshot fields (status, ready, process_running, resolved_url, config.*, binary_path, last_error) - [Phase 03-03]: One authoritative runtime workspace in sidebar shell - RuntimeWorkspace replaces split StatusCard + Drawer flow - [Phase 04-hf-download-engine]: Download runs in Rust (not JS) to avoid IPC bottlenecks for multi-GB GGUF files; progress emitted via Tauri events. - [Phase 04-hf-download-engine]: Direct resolve URL `https://huggingface.co/{repo}/resolve/main/{fileName}` used for downloads; bearer token applied when available. - [Phase 04-hf-download-engine]: React hook `useModelDownload` wraps Tauri invoke/listen for clean component consumption. - [Phase 04-hf-download-engine]: `.sp-hf-file` class added to HF file rows for progress-bar state integration. ### Pending Todos None yet. ### Blockers/Concerns - None currently; Phase 4 complete and verified. ### Quick Tasks Completed | # | Description | Date | Commit | Directory | |---|-------------|------|--------|-----------| | 1 | Investigar e corrigir bug de internal error na segunda mensagem do chat | 2026-03-30 | abb9db0 | [1-investigar-e-corrigir-bug-de-internal-er](./quick/1-investigar-e-corrigir-bug-de-internal-er/) | ## Session Continuity Last session: 2026-03-31T00:25:00.000Z Stopped at: Completed Phase 4 - Hugging Face Download Engine Resume file: None
