Render every selected review event, including events without current story membership, and label current grouping without inventing historical assignments. Keep history selection inside the central canvas heading, use shared camera controls, and fit the default scene within the viewport.
Validation: 46 focused tests, synthetic and read-only portable-data Electron checks, Node/Agent/Web typechecks, targeted ESLint, and diff checks passed. All 21 reported events remain represented at wide and narrow widths; no live data writes or model calls.
Release note: Historical story spirals now retain unassigned events. Review history sits inside the canvas column, and camera controls have consistent spacing and framing.
Share review history selection between overview and graph while preserving explicit navigation and stale-response guards. Return attention for the selected review scope and interval, and align spiral events and time with that review.
Normalize radii from message rates, including partial turns, without lifting quiet turns toward peaks. Preserve one continuous helix, uniform time height, round turn sections, and smooth transitions; equal densities retain equal radii. Document current-message and hourly-bucket limitations.
Validation: 51 focused unit tests, 2 production IPC tests, Electron DOM and geometry checks, Node/Agent/Web typecheck, targeted ESLint, and diff checks passed.
Release note: Story graphs now offer synchronized review history selection, and spiral radii reflect recorded message density within the selected review.
Each source version is extracted once for every review scope; events carry spans and projects from their sources, and attention density is counted from messages. After publication, events are assigned to project features and sub-threads (cross-project stories only when enabled), with user rename, merge, remove, move and undo. The story graph gains a lazily loaded Three.js time-spiral view. Includes the 3D concept demo, real-data DeepSeek check scripts and docs.
