Draft CAND-0018 Capability Contract Boundary from a screened AI-chat lead

Browse source 
history/260927-ComplexWebAppUiComponents_chatgpt.txt is a pasted AI-chat
transcript on UI-integration architecture. It fails this repo's primary-source
bar (unauthored, unverifiable broken citation markers), so it is screened as
a leads-only document, not cataloged as a source, and never cited as evidence.

Instead read the two real specs it pointed to: MDN Custom Elements (SRC-0046)
and webpack Module Federation (SRC-0047). Neither defines a semantic UI
capability contract (inputs/events/commands/slots) as a first-class concept;
that gap motivates the new draft hypothesis, distinct from the existing
Independent Feature Boundary (release cadence) and Vertical Feature Slice
(source grouping) candidates.
