docs: add ADR-0035 on structural vs value-dependent Any conflicts#296
Merged
Conversation
Record the rule that Any.Uri() and AnyString jointly establish: an illegal
constraint combination is made unrepresentable at compile time through a
typed progression when the illegality is structural (a mailto has no port),
and is left to the run-time ConflictingAnyConstraintException /
AnyGenerationException path when it depends on a generated value
(Numeric().StartingWith("ORD-") versus the valid "123").
Capture the decision, its rationale, the three rejected alternatives
(all-flat, all-typed, analyzer-over-flat) and the consequences in English
(canonical) with the French translation alongside, and add it to the index.

Summary
Record, as ADR-0035, the design rule that the
Anysurface enforces constraint conflicts at two different points depending on the nature of the error: a structural (category) conflict is made unrepresentable at compile time through a typed progression, while a value-dependent conflict stays on the run-time exception path.Any.Uri()(PR #295) is the rule's first typed-progression application; the existingAnyStringsurface is its run-time counterpart. This records a decision that was established but not yet written down.Type of change
