Verified pair

The 1.0 Beta generation pair — minor releases within it stay compatible.

A new generation starts the specification’s migration timetable; historic releases are archived, and installed copies keep running — no remote revocation.

Source boundary

.lucc is logic, .lucu is description — enforced by both CLIs, one way only.

Luca Code owns general-purpose logic in .lucc; Luca UI owns declarative descriptions in .lucu. Extensions never change meaning across the boundary. The dependency is one-way — luca-ui depends on luca-code by relative path and reuses only its public library. Luca Code never depends on Luca UI; its suite, behavior, and user files are untouched by UI work.

What 1.0 stable still needs

Validation and stabilization of this Beta only — no new feature milestones.

Defect fixes plus the design record for the explicitly open items (full component inventory, timing, theme tokens, resource formats, adapters — routes are locked out).

Do not publish this build as stable and do not label it 1.0. The version reads 1.0 Beta everywhere until the stabilization milestone completes.
