 # 0119 — UFCS dot-call on a GENERIC free function: "unresolved '<name>'"
 
+> **RESOLVED — not a bug** (2026-06-11, Agra language ruling, same
+> session). Dot-form UFCS on generic free functions is NOT the language
+> contract: UFCS free-function dot-dispatch is the annotated mechanism
+> (`name :: ufcs target;`, concrete targets), and the FLUENT spelling
+> for free functions is the pipe operator — `xs |> first_of()` desugars
+> at parse time to `first_of(xs)`, which dispatches generics through
+> the normal monomorphization machinery (verified:
+> `context.allocator |> create(Session)` works). specs.md §UFCS
+> corrected (it overstated "works with ... generic functions" for the
+> dot form). No compiler change. MEM Phase 2.2 unblocked — helpers
+> shipped as free functions with the direct + `|>` contract
+> (examples/0838-memory-helpers.sx pins both spellings).
+> Residual corner (not contracted, unfiled): a `ufcs` ALIAS naming a
+> generic target also doesn't dot-dispatch; file separately if ever
+> wanted.

 ## Symptom
 
 `obj.func(args)` where `func` is a generic free function (any `$T` in its
