A free function's $o comptime value param binds via lowerComptimeCall → bindComptimeValueParams. The generic-struct-instance method path (b.pick(.b)) took a different dispatch route: genericInstanceMethod → ensureGenericInstanceMethodLowered emitted a plain call to the monomorphized FuncId, never checking hasComptimeParams — so the method's $o was never bound and lowered to 'unresolved o'. Fix: when the selected generic-instance method declares comptime params, route through the new lowerComptimeGenericInstanceMethod, which composes the two mechanisms — installs the struct instance's type_bindings (so T / *Box(T) resolve), pre-binds the receiver self as a normal pointer-param alloca (so self.field reads work in the inlined body), then routes the remaining ($) params through lowerComptimeCallArgsSkip(skip_params=1). That reuses bindComptimeValueParams, so comptimeIntNamed / comptimeValueRefNamed resolve the value param inside the method body, identically to the free-function path. lowerComptimeCall is refactored into lowerComptimeCallArgs(Skip) cores parameterized over the effective arg-node slice + a leading skip count; the original free-call entry point is unchanged behaviorally. Loud-diagnostic behavior preserved: a non-constant / unknown-variant arg still emits the value-param diagnostic, never a silent default. Int value params ($n: i64) remain unbound — a pre-existing limitation shared with free functions, orthogonal to this fix. Locks examples/0642 (enum + tagged-union comptime value params on a generic-struct method, incl. self.field read and comptimeIntNamed via a type-position [o]i64).
