Extend make adapt-lit beyond tokens: parse src/elements/*.js, compare each IR
component contract against its <wn-*> element, and emit per-component drift
reports + a machine roll-up (adapters/lit/drift/), with write-once stubs
(adapters/lit/stubs/) for genuinely new components. Never overwrites
hand-authored sources.
- Severity split: actionable drift (prop-missing, attribute-mismatch,
variant-axis-missing, tag-mismatch) gates with exit 3; non-portable + prop-extra
are informational (the IR carries React style/onClick; Lit is richer than the
minimal designbook) and don't gate.
- Current state: 7 ok, 3 actionable drift for human triage — PipelineStrip
(wn-pipeline-strip vs hand-authored wn-pipeline rename), PageHeader (actions is
a slot, not a prop), Sidebar (IR 'current' axis absent on the element).
- _report.json reuses generatedAt/irRef when drift is unchanged (no git churn).
