codegen: emit package directories as C# namespaces instead of static wrapper classes (R-AX phase c; relaxes the lib/lib.spy refusal of #1932)

codegen: `5 as! Color` emits an unchecked (Color)5 for an undefined enum value where python raises ValueError — as!/as? must agree per pair (R-AY sibling of #1892)

bug

#1947

semantic: add an error-sentinel type so a refused expression yields exactly one diagnostic — refusal sites return Unknown, which doubles as the permissive channel (R-AZ, P17 phase 1)

#1946

core: `=` alignment on a string operand is not refused — `format('ab', '05')` prints `000ab`

bug

#1945

core: `format(1.5, '+%')` drops the `+` sign under the `%` type

bug

#1944

· antonsynd opened

on Sep 20, 2026

core: `str.format` has no nested replacement field in the spec position — `"{:{}}".format(x, spec)` reports `Unknown format code '{'`

bug

#1943

· antonsynd opened

on Sep 20, 2026

semantic: a method group in VALUE position still prints a System.Func outside the backtick column — xs.count (Sharpy surface) and s.get_type_code (reverse-mangled)

#1942

· antonsynd opened

on Sep 20, 2026

semantic+codegen: a nested-type chain used as a QUALIFIER is untyped — Outer.Inner.zzz is SPY0908, and the emitter has no carrier for a nested type under a constructed generic

#1941

· antonsynd opened

on Sep 20, 2026

Allowlist issue-state gate blind spots: build_tools/spec_blocks_allowlist.txt (589 rows, zero issue refs) is outside its glob, and C# comment rosters (BUG(#N), N/A tables, KnownRed) are invisible to it

#1939

· antonsynd opened

on Sep 20, 2026

codegen: a struct auto-property with a default value emits a field initializer with no explicit constructor — CS8983 behind SPY0908

#1938

· antonsynd opened

on Sep 20, 2026

codegen: an underscore-prefixed field in a struct is emitted `protected` — CS0666 behind SPY0908

#1937

· antonsynd opened

on Sep 20, 2026

builtins: bool(()) on the zero-arity tuple returns True; python returns False (the object overload swallows the tuple)
