facett-gantt — crate card

Reverse-engineered (from source — verify, don't trust the name)

• One-line pitch: A pure-egui Gantt chart facet: dependency-linked task bars with progress over a time axis.
• Does: Draws Tasks as one-row bars over a time axis with dependency arrows (blocks/depends-on, via Task::dep) and a progress fill; computes and can highlight the critical_path(). Derives naturally from a case's stage/task DAG + dates for planning an ärende's handläggning or a project. Gantt follows the facett Facet contract (title/ui/state_json); ui() returns the selected task. Deterministic (host-supplied "today").
• Key deps: egui, chrono, serde/serde_json. Optional facett feature.
• Shape: lib, ~313 LOC single lib.rs (Task, Gantt; includes a critical-path computation).
• Observed role in the workspace: Standalone widget, no in-repo consumer yet. Built in ordning; destined for facett.

• Primary consumer(s):
• Why it exists (vs the obvious alternative):
• Hard constraint (airgap / no-C-deps / no-FFI / pure-Rust / etc.):
• Release cadence & independence (rides a parent? own repo someday?):
• Status (production / prototype / experimental / stubbed):
• Must-NOT-change invariant:
• Biggest known gap or TODO:
• Anything a newcomer would get wrong about it:
