mesalogo 5dc65457d9 feat: shared supervisor timeline, story assignment and time-spiral view
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.

Memory evidence is current background, not an event in the review interval. Its occurredAt is the actual last update time, not a historical content snapshot. Do not infer when its current content first became true or turn it into a historical event.
Task status is current, not a snapshot at the review end. Use only supplied creation or completion timestamps within the review interval for task events.
Automatic evidence can contain only a portion of a source (locator start/end). Describe only that portion; do not imply the entire source or interval was reviewed. Previous summaries and known entity descriptions are background, not new events.
Use source reference IDs exactly as provided. Entity IDs are local to this output, not identities across runs.
To identify an existing concept, copy its candidateRef from KNOWN ENTITIES. For a new concept omit candidateRef. Never generate database IDs or infer identity from local IDs or labels.
Do not invent source IDs or merge unrelated concepts.`
