  Line / column errors :active, d2, after d1, 4d
  section Export
  SVG plan : d3, 2026-11-08, 2d
  Non-blank PNG check : d4, after d3, 3d
→ gantt: 2 sections / 4 tasks; CJK title, done/active statuses, after dependencies and 3d durations are preserved; SVG contains section, task and task-date groups.

Limits and failure handling

excludes/includes/todayMarker are recorded but not drawn; no real calendar, workday or critical-path computation. The fixed examples use readable 2026-11 dates and do not represent a completed test run.

FAQ

Are incomplete tasks rejected?

Yes: MALFORMED_TASK points just after the colon; a missing colon returns MISSING_TASK_SEPARATOR.

Are dates mapped to a real timeline?

No. This run records the raw date/duration text and draws deterministic task bars; it is not real Mermaid timeline layout.
