The crate the browser epic hangs off: Command (the wire format), ViewState, RenderCache/CellDisplay/Snapshot, and reduce_view. It depends on improvise-core and serde and nothing else -- no IO, no command layer, no terminal -- and improvise-command now depends on it. ViewState, ViewCursor, ViewFrame, AppMode, Panel, MinibufferConfig, MinibufColor, HELP_PAGE_COUNT and the key types move here. Everything that moved is re-exported from ui::app and command::key, so no existing path changed. The three tickets before this one are what made the move mechanical: h0b evicted the unportable fields, a2x added the derives, 8uz took the cursor out of the shared View. Command's client->server half is not invented. It is exactly the set of EffectKind::ViewOnly effects whose target is the portable slice -- h0b had already sorted the portable state from the host-local, so the enumeration was done. Effects touching the wizard, staged drill edits, storage or the layout cache are absent by construction. The other half carries projections: already-formatted display values and their labels. One thing had to be added rather than moved. reduce_view runs on a client that holds no Workbook, and ViewState::cursors is keyed by view name, so ViewState needs its own active_view. That makes two copies of "which view is active"; App::switch_to_view and App::install_workbook are the only writers, and the_two_active_view_names_never_diverge guards it. The 8uz characterization test caught the desync the moment it appeared, because it was calling workbook.switch_view directly. Whether the two are *allowed* to diverge -- two clients on different views -- is improvise-g0f, deliberately left open. It changes the shape of improvise-cqq, and nothing here forecloses either answer. reduce_view has 12 tests including a determinism check: folding the same stream twice gives the same state, which is what stops the server's mirror drifting from the client it mirrors. Every Command round-trips through JSON. The crate is in the CI wasm job.
