+; specs/compiler/zig_open_slice.t27 -- an OPEN-ENDED slice `a[lo..]` lowers to a Zig slice, not an index.
+; --
+; The defect (#8200, also #6250). The parser marks `a[lo..]` as a slice with no end child
+; (`slice_open`), but the gen-zig emitter only knew the bounded form and fell through to plain
+; indexing: `a[2..]` came out as `a[2]`, one element. A typed local then failed to compile, and a
+; byte row handed to `std.debug.print("{s}", .{row[0..]})` reached Zig as `.{ row[0] }`, which zig 0.16
+; refuses with "invalid format string 's' for type 'u8'". Found while streaming raw RGB frames from
+; specs/t27f/reel_particles.t27 (#10308), whose workaround was to pass the whole array.
+; --
+; The rule. `a[lo..]` keeps its range and runs to the end; `a[lo..hi]` keeps both bounds.
