Description
W&B LEET — Multi-Run Workspace
Quick start
By default, LEET opens the workspace and selects the latest run. Set
startup_modetosingle_run_latestin the config to go straight into single-run view instead. Providing a path always opens single-run view.What's new?
LEET now opens into a workspace view by default — a multi-run experience with three panels:
Press
Enterto drill into a single run,Escto return. The workspace keeps all watchers and heartbeats alive in the background, so returning is instant.New key bindings (workspace)
Spaceselect/deselect run •ppin run •[ / ]toggle sidebars •Tab / Shift+Tabcycle sidebar focus •/filter metrics •Enteropen run •Escback •hhelpArchitecture notes (for reviewers)
## Model hierarchy Model (top-level) owns a Workspace (always alive) and optionally a Run (created on Enter, cleaned up on Esc). Message routing: help overlay → active sub-model → mode transitions. Non-input messages are forwarded to the workspace even while viewing a single run, keeping directory watchers and heartbeats current.Workspace data path
Directory watcher: polls wandb/ for run directories, emits WorkspaceRunDirsMsg.
Per-run readers: each selected run gets its own WandbReader + WatcherManager, keyed by run directory name. Batched records are tagged with WorkspaceChunkedBatchMsg / WorkspaceBatchedRecordsMsg to route to the correct run.
Overview preloader: unselected runs get lightweight preloads (just the RunRecord) for the overview sidebar, capped at maxConcurrentPreloads.
Shared heartbeat: a single HeartbeatManager + channel serves all live workspace runs.
Multi-series metrics grid
The existing MetricsGrid / EpochLineChart now support multiple series per chart. Each run's data is keyed by its .wandb file path. PromoteSeriesToTop ensures the pinned run renders last (on top). Color assignment uses a stable hash of the run path into the active palette.
Run selection & pinning
selectedRuns map[string]bool tracks which runs contribute data to the metrics grid. pinnedRun (at most one) gets visual priority: its series draws on top and its list entry shows ▶. Deselecting the pinned run auto-unpins it.
###Sidebar layout
Both sidebars use AnimationState for smooth expand/collapse. When both sidebars are visible, widths use SidebarWidthRatioBoth (≈ 0.236, derived from φ); when only one is visible, SidebarWidthRatio (≈ 0.382). Focus management: exactly one sidebar receives keyboard input at a time, resolved by resolveSidebarFocus.
